TECHNICAL FIELD & BACKGROUND ART
[0001] The present invention relates to a record book or pad of the type having record sheets
and removable sheets in overlying relationship and which are disposed alternately
to provide pairs each with one record sheet underlying one removable sheet. Such books
or pads are known, for example as discussed in our G.B. Patent Specification 2,214,131B
in which image transfer means is provided between the record sheet and removable sheet
in each pair so that a marking applied by pressure to a removable sheet is reproduced
on the underlying record sheet with which it is paired. A so-marked removable sheet
may then be removed from the book or pad for presentation as required while a record
of the marking is maintained on the record sheet of the book or pad.
[0002] A popular and commercially successful form of image transfer means provided between
a removable sheet and record sheet in a pair results in direct image transfer of a
marking between the two sheets (that is without the necessity of interposing conventional
carbon copy paper between the pair of sheets). Such form of direct image transfer
means is well known in the art and generally one or both of the directly opposing
faces of the record sheet and removable sheet in a pair are formed or treated so that
they respond to the pressure of marking on the removable sheet to reproduce a copy
of the marking on the record sheet. For example, one or both of the aforementioned
opposed faces of the sheets may have minute ink capsules which burst in response to
the pressure of marking to reproduce the marking on the record sheet or the aforementioned
opposed faces may have chemically reactive coatings that inter-react in response to
the pressure of marking to produce a copy of the marking on the record sheet. Examples
of sheets which incorporate direct image transfer means having ink capsules are sold
under the Trade Mark NCR and examples of sheets having reactive coatings are marketed
under the Trade Name Idem by Wiggins Teape Carbonless Papers Limited and under the
Trade Name Signal by Carrs Papers Limited; many other sheets are known which incorporate
direct image transfer means such as those provided by Mead Products Inc., and Waterlow
Petty.
[0003] With record books or pads of the kind discussed having sets of removable sheets and
record sheets disposed in pairs with direct image transfer means between the sheets
of each pair it is advisable during use to interpose a barrier sheet between the record
sheet of the uppermost pair of sheets and the removable sheet of the immediately underlying
pair. The purpose of the barrier sheet is to alleviate the pressure of marking the
removable sheet above the barrier sheet from being transmitted to cause a reproduction
of the marking on a record sheet beneath the barrier sheet. As a consequence a user
of the record book or pad frequently has to reposition the barrier sheet between successive
pairs of sheets with the inconvenience of ensuring that the barrier sheet is correctly
placed between appropriate record and removable sheets of adjacent pairs. It is an
object of the present invention to provide a record book or pad of the kind generally
discussed and by which the aforementioned inconvenience may be alleviated.
STATEMENT OF INVENTION & ADVANTAGES
[0004] According to the present invention there is provided a record book or pad comprising
record sheets and removable sheets in overlying relationship, the sheets being disposed
alternately to provide pairs with a removable sheet overlying a record sheet in each
pair; each record sheet having a longitudinally extending spine part adjacent to a
spine edge of the book or pad; binding means engaging said spine parts to maintain
the record sheets in book or pad form; direct image transfer means for each pair of
sheets whereby a marking applied by pressure to each removable sheet directly forms
a copy of that marking on the underlying record sheet paired therewith; and wherein
the record sheet and removable sheet of each pair have longitudinally extending leaf
edge parts spaced laterally from the spine edge and said leaf edge parts of the sheets
in a pair are retained together by means which facilitates the sheets in a pair to
be turned about the binding means from said leaf edge parts in unified manner and
permits the removable sheet or a portion thereof to be readily removable from the
record sheet with which it is paired.
[0005] By the record book or pad of the present invention the removable sheet and record
sheet in each pair are retained together at longitudinally extending leaf edge parts
of those sheets from which leaf edge parts they can be turned together as a pair of
sheets, in a similar manner to a single page, about the binding means. By this arrangement,
it is a simple matter to insert a barrier sheet, such as a plastics sheet or card
successively between the pairs of sheets and the possibility is alleviated of inadvertently
inserting the barrier sheet between the removable and record sheets of a pair. Furthermore,
the retention between the leaf edge parts in a pair of sheets is arranged so that
the removable sheet is readily removable, for example by peeling or tearing, from
the record sheet in its pair whereby following the application of a marking to the
removable sheet, that sheet may be removed from the record book or pad and presented
or displayed as required while a copy of the marking is retained on the record sheet
within the book or pad.
[0006] The direct image transfer means for directly forming a copy of a marking applied
to a removable sheet on the record sheet paired therewith may be of a kind well known
in the art such as the previously mentioned examples of ink capsules on either or
both of the directly opposed faces of the sheets in a pair and which capsules burst
in response to the marking pressure or by reactive coatings on the directly opposed
faces of the sheets in a pair which inter-react in response to marking pressure to
provide the copy on the record sheet.
[0007] Generally the record book or pad will be of rectangular configuration in which the
spine edge forms one side edge (which may be a top or bottom edge) of the book or
pad and the leaf edge parts of the record sheets and removable sheets are located
at a leaf edge of the book or pad that is parallel with the spine edge and forms the
opposite side edge of the book or pad.
[0008] In one form of construction the removable sheet and record sheet of a pair may, in
effect, be continuous one with the other and folded in the region of the respective
leaf edge parts into the required overlying relationship for the removable sheet to
be readily removable from the record sheet with which it is paired by tearing along
the region of the fold. To facilitate this latter tearing, a longitudinally extending
line of weakness may be provided at the leaf edge part of the removable sheet, conveniently
along a line of the fold.
[0009] In another form of construction the leaf edge parts of the record sheet and removable
sheet in a pair may be retained together by adhesive and the removable sheet of that
pair provided with a line of weakness which permits a portion of that removable sheet
to be removed from its leaf edge part which remains adhesively secured to the record
sheet with which it is paired.
[0010] In a still further form of construction the leaf edge parts of the record sheet and
removable sheet in a pair may be retained together by a low tack adhesive carried
by the removable sheet. The use of low tack adhesive is well known for paper stationery
products such as message or memo pads of the type sold under the Trade Mark "NOTE
STIX" or the Trade Mark "POST IT" notes where the adhesive provides relatively low
adhesion characteristics which permit repeated adhesive contact and removability of
a sheet from a receptive surface (which may be, for example, of paper, wood, metal
and plastics) and which, upon removal, substantially none of the low tack adhesive
is deposited on the receptive surface. By use of such low tack adhesive to retain
the leaf edge parts of the record sheet and removable sheet in a pair together it
will be apparent that the removable sheet or a portion thereof (which will typically
bear a manuscript note of a telephone message) when peeled or removed from the book
or pad and carrying the low tack adhesive can temporarily be attached by its low tack
adhesive to a receptive surface where it may be prominently displayed. Where the removable
sheet carries a low tack adhesive the record sheet may carry a release agent with
which the low tack adhesive of the removable sheet contacts to retain the leaf edge
parts of the sheets in a pair together whilst the release agent facilitates removal
of the low tack adhesive on the removable sheet from the record sheet.
[0011] The binding means for the record sheets preferably permits the sheets which are bound
together to be turned from their overlying relationship in the book or pad and substantially
through 360° into back-to-back relationship. This has the advantage of maintaining
the book or pad in a compact condition while successively presenting new removable
sheets for use. The binding means is preferably in the form of a ring or spiral binding.
[0012] The binding means may engage solely the record sheets in the pairs of sheets in which
case the number of sheets at the spine edge of the book or pad may be half the number
of sheets presented by the pairs of sheets.
[0013] Alternatively, the removable sheet of a pair may have a filler sheet portion by which
that removable sheet extends to provide a spine part adjacent to the spine edge of
the book or pad and the binding means may engage the filler sheet portions to retain
those portions in the book or pad whilst the removable sheet or a portion thereof
is readily removable from the filler sheet portion with which it is associated. With
this arrangement the number of sheets provided at the spine edge of the book or pad
and with which the binding means engages can correspond with the number of record
and removable sheets so that the stack of sheets in the book or pad present a uniform
thickness from the spine edge to the leaf edge parts. The filler sheet portion may
be in the form of a strip separate from the removable sheet with which it is associated
or alternatively the removable sheet and filler sheet portion with which it is associated
may be connected together through a longitudinally extending line of weakness which
permits the removable sheet (or a portion thereof) to be torn easily from the filler
sheet portion so that the latter remains as a stub on the binding means in the book
or pad.
[0014] The previously mentioned barrier sheet will usually be made available with the book
or pad and is preferably incorporated in the book or pad to be capable of being interposed
selectively between two adjacent overlying pairs of record and removable sheets to
alleviate marks applied by pressure to a removable sheet above the barrier sheet from
being reproduced on a record sheet beneath the barrier sheet. Preferably the barrier
sheet is formed as part of a cover for the book or pad which is adjustable to be inserted
between two adjacent overlying pairs of record and removable sheets in a direction
normal to the longitudinally extending leaf edge parts.
[0015] The removable sheet of a pair may be sub-divided by divisions (which will usually
extend perpendicularly relative to the spine edge) into at least two planar sheet
portions (typically four of five sheet portions in a telephone message book), each
of which sheet portion is removable independently from the record sheet with which
that removable sheet is paired. Usually the sheet portions of a removable sheet will
be paired with a single record sheet which is common for those sheet portions.
[0016] The record book or pad may, in use, be intended to have the bound spine edge at the
top, bottom or a side edge of the book or pad, the position of the spine edge in use
usually being determined by the orientation of text which will often be printed on
the removable sheet (possibly with corresponding printing on the record sheet). For
example, text may be printed on the removable sheet so that when such text is read
in conventional manner, the bound spine edge is on the righthand side of the book
or pad, this may be particularly convenient for lefthanded users to ensure that the
binding means is clear of the writing hand.

DETAILED DESCRIPTION OF DRAWINGS
[0018] The record books or pads illustrated are typically used for issuing memoranda or
taking notes of telephone messages and each comprises a stack of overlying paper sheets
which consist of alternately disposed removable sheets 1 and record sheets 2. The
sheets are formed in pairs, each of which has a removable sheet 1 overlying a record
sheet 2. The sheets 1 and 2 are rectangular so that a stack of several pairs of the
sheets in overlying relationship will provide the book or pad with a generally rectangular
profile. Usually the pairs of sheets in a book or pad will be of identical form. A
longitudinally extending spine part 3 of each record sheet 2 is provided with apertures
4 by which the record sheets in a stack of the sheet pairs are bound in book or pad
form by binding rings 5 located at a spine edge 6 of the book or pad to extend through
the holes 4.
[0019] The removable sheet 1 and record sheet 2 have longitudinally extending leaf edge
parts 10 and 11 respectively which are parallel with the spine edge 6 and spaced laterally
therefrom. The leaf edge parts 10 and 11 of a pair of sheets coincide and present
a leaf edge 7 to the book or pad when the pairs are stacked and retained by the binding
rings 5. As will be seen from Figures 1 to 4, each removable sheet 1 has a width or
lateral extent from the longitudinally extending leaf edge 7 which is less than the
width or lateral extent of the record sheet 2 from that edge 7. In each case the leaf
edge parts 10 and 11 of the sheets 1 and 2 in a pair are retained together 50 that
a pair of sheets can be turned from the leaf edge 7 in unified manner, effectively
as a single page, about the binding rings 5. The binding rings 5 (or an equivalent
spiral binding) is preferred so that the pairs of sheets in the book or pad can be
turned successively through 360° about the rings 5 into back-to-back relationship.
[0020] The removable sheet 1 and record sheet 2 in a pair have faces 1A and 2A respectively
which directly oppose each other in overlying relationship and either or both of these
faces is provided with direct image transfer means by which a marking applied by pressure
on to the upper exposed face of a removable sheet 1 may be reproduced on the underlying
face 2A of the record sheet with which that removable sheet is paired. In Figure 1
this is indicated by marking the word "MESSAGE" on the removable sheet 1. The direct
image transfer means can be of a kind well known in the art such as those previously
discussed herein where the faces 1A and 2A may contain minute ink capsules which burst
in response to the marking pressure to provide the reproduction on the face 2A or
where the faces 1A and 2A have reactive coatings which inter-react under the marking
pressure to provide the copy on the face 2A.
[0021] In the embodiment of Figures 1 and 2 the leaf edge parts 10 and 11 are retained together
by a longitudinally extending line of permanent adhesive 20. Provided in the removable
sheet 1 is a line of weakness formed by a longitudinally extending array of perforations
21 which extend parallel with and adjacent to the adhesive line 20. With this arrangement
and following use of a pair of sheets 1 and 2 to reproduce a mark or message applied
to the removable sheet 1 on the record sheet 2, a portion 1' of the removable sheet
can be torn along the line of perforations 21 and removed from the record sheet 2
with which it is paired. The portion 1' of the removable sheet can thus be presented
as required while a record of the marking is retained on the sheet 2.
[0022] In Figure 2, and purely for convenience of illustration, the record book or pad is
formed with three pairs of sheets shown in Figure 1 but in practice many more such
pairs are likely to be provided. During use of the book or pad a barrier sheet 25
(usually of relatively thick card or plastics) will be inserted between the two adjacent
uppermost pairs of sheets in the stack. The purpose of the barrier sheet 25 is to
prevent the pressure applied during marking of the uppermost removable sheet 1 in
the stack from being transmitted to a record sheet 2 which is located beneath the
barrier sheet so that unwanted copies of the marking are not inadvertently reproduced.
Following use of the top pair of sheets in the arrangement shown in Figure 2 and removal
of the sheet portion 1', the record sheet 2 of the top pair can be turned through
360° on the rings 5 (carrying with it the leaf edge part 10 of the removable sheet
with which it was paired) into back-to-back relationship with the bottom sheet. The
barrier sheet 25 can now be repositioned to be interposed between the adjacent record
and removable sheets of the successive two adjacent pairs of sheets. By having the
sheets 1 and 2 in a pair retained together at their leaf edge parts it will be apparent
that the succesive pairs of sheets can be easily separated from each other at the
leaf edge 7 for selectively positioning of the barrier sheet 5 in a direction through
the leaf edge of the book or pad - this alleviates the possibility of inadvertently
inserting the barrier sheet 25 between the record sheet and removable sheet of a pair.
[0023] In the embodiment shown in Figure 3 the leaf edge parts 10 and 11 of the removable
and record sheets in a pair are retained together by a longitudinally extending line
of low tack adhesive 30 carried by the face 1A of the removable sheet. Following use
of a pair of sheets to reproduce a marking on the record sheet from marking applied
by pressure to the overlying removable sheet, the removable sheet 1 is pulled or peeled
as a whole from the record sheet 2 with which it is paired carrying with it the strip
of low tack adhesive 30 by which that removable sheet can temporarily be adhered to
a receptive surface. Low tack adhesive and its characteristics are well known in the
art of stationery materials as previously discussed herein and as such further discussion
is considered superfluous. However, it will be usual for the leaf edge part 11 on
the face 2A of the record sheet to be provided with a release agent (such as a silicon
coating) with which the low tack adhesive contacts to facilitate removal of the removable
sheet from the record sheet when required.
[0024] In Figure 3 a barrier sheet 25A is provided (to serve a similar purpose as the barrier
sheet 25 in Figure 2) which is formed as part of a cover or jacket 25B for the front
and back of the book or pad. The cover 25B is adjustable for its barrier sheet part
25A to be repositioned selectively and successively between the pairs of sheets in
the stack by inserting the barrier sheet in a lateral direction through the leaf edge
of the book or pad. When the book or pad is not required for use, the barrier sheet
part 25A may be positioned to overlie the uppermost removable sheet 1 in the stack
of pairs to provide a protective front cover. A similar cover 25B may be provided
for the other embodiments discussed herein.
[0025] In the embodiment of Figure 4 the removable sheet 1 and record sheet 2 of a pair
are formed from a single sheet of paper which is folded along a line 40 into the overlying
relationship required of the sheets in that pair, the fold line 40 being effected
between the leaf edge parts 10 and 11 of the respective sheets 1 and 2. The aforementioned
single sheet may also be provided with a longitudinally extending line of weakness
in the form of an array of perforations 40A presented at the leaf edge of the book
or pad along the fold line 40 between the leaf edge parts 10 and 11 of the sheets
in the pair. With this arrangement it will be appreciated that following use of the
sheets in a pair to reproduce a marking on the record sheet 2 applied by pressure
on the removable sheet 1, the removable sheet 1 may be torn from the book or pad along
the weakness formed by the fold line 40 (or more conveniently along the line of perforations
40 which may be provided); furthermore the pair of sheets may be turned on the ring
binding from the leaf edge 7 in unified manner to facilitate location of a barrier
sheet as previously discussed. By forming the removable sheet and record sheet in
a pair by folding a single sheet, the direct image transfer means applied to either
or both the faces 1A and 2A of those sheets may conveniently be applied to one face
of the single sheet.
[0026] If required the removable sheet 1 can carry a region of low tack adhesive on its
face 1A remote from its leaf edge part 10 to facilitate temporary adherance of that
sheet to a receptive surface when removed from the record book or pad; such a region
of low tack adhesive is indicated as a strip 50 in Figure 4 along the edge of the
sheet 1 remote from and parallel to its leaf edge part 10 - similarly located strips
50 may be provided on the removable sheets 1 in Figures 1 to 3 and 5. The strips 50,
if provided, conveniently serve to stabilise the position of the removable sheet 1
on the record sheet 2 of its pair during the application of a marking to the removable
sheet.
[0027] It will be seen from Figure 2 that the pairs of sheets in the book or pad are bound
by the rings 5 solely through the spine edge parts 3 of the record sheets so that
the number of sheets engaged by the rings is half that of the number of sheets in
the pairs in the book or pad. This will also apply to the arrangement shown in Figures
3 and 4 and may be inconvenient for binding purposes. To alleviate this the previously
described books or pads may be modified as shown in Figure 5 in which the removable
sheet 1 is effectively extended to fully overlie the record sheet 2 with which it
is paired and to be incorporated in the binder rings 5. For this purpose each removable
sheet is provided with a coplanar spine edge part in the form of a filler sheet or
strip 45 having holes 46 through which the binding rings 5 are received. The filler
strip 45 may be separate from its associated removable sheet 1. Alternatively the
removable sheet 1 may be attached to the filler stip 45 through a line of weakness
such as a longitudinally extending array of alternately disposed long slits 47 and
short tags 48 which permit the removable sheet 1 to be readily torn from the strip
45 prior to that removable sheet 1 being ripped or removed from the record sheet with
which it is paired. By providing each removable sheet with a filler strip 45 it will
be realised that the number of sheets with which the binding engages corresponds to
the number of sheets presented by the pairs in the record book or pad.
[0028] In Figure 1 the removable sheet 1 is subdivided by a laterally extending line of
weakness 55 into separable portions of that sheet so that each portion may be individually
removed from the book or pad following use by tearing along the line of weakness 55.
Such sub-division is optional and may be applied to the other embodiments discussed
herein. Typically record books for telephone messages will have the removable sheet
1 sub-divided into four or five separable portions by longitudinally spaced and parallel
lines of weakness 55.
[0029] Usually the removable sheet 1 will have a printed text convenient for the guidance
of users in applying a message thereto (it will also be usual for the record sheet
2 to have a corresponding printed text) and this text will normally determine the
orientation of the book or pad in use, for example whether the spine edge 6 is at
the top, the bottom or a side edge of the book or pad. In Figure 1 the "MESSAGE" is
shown applied with the spine edge at the lefthand edge of the book or pad (as is usually
convenient for righthanded users) but it will be appreciated that with appropriately
orientated text on the removable sheet 1 the spine edge 6 may be intended to be on
the righthand edge of the book or pad as convenient for lefthanded users to alleviate
the possibility of the binding rings 5 interfering with the writing hand.
