DELIVERY EQUIPMENT FOR COWS

Description

[0001] This invention is a tool which is used for calving. In difficult deliveries the animal must be helped. This is done by attaching ropes to the front or hind hooves of the calf and assisting the cow during the contractions by pulling on the calf up to a force of 180 N. This obviously takes more than one person. Therefore, delivery equipment has been brought into the trade to make things easier. This generally consists of a long tube on which there is a sliding lever mechanism. On one end of the tube there is a horizontal support which is placed on the cow's rump below the vulva. Such a structure is described in the German Patent 1 133 076. Its advantage is that one person has enough strength to operate it which means that difficult deliveries can now be done by one person. Its disadvantage, however, is that the horizontal support placed against the rump of the animal below the vulva is not very secure and only permits downwards traction (from a standing cow). When it is used for pulling upwards, which is necessary for example in a breech birth, the support slips downwards towards the udder. This also happens with very difficult deliveries and ones where the cow is lying but not stretched out. This means somebody has to hold the support in place while a second person operates the lever. The object of this invention is to produce delivery equipment of this type without the disadvantages mentioned above. In the delivery device described here the simple horizontal support is replaced by a curved tube which is placed against the animal and forms a complete, or almost complete, circle. The circle runs below the vulva of the animal, along the ischium to above the back of the animal's back. This makes slipping to the left or right up or down impossible. The support has two hinges attached to a forked end. The other end of the fork leads into a lever mechanism of the usual type so that this part can be moved up or down without the support moving. This allows traction to be placed on the calf both upwards and downward. The above object is achieved by means of a calving device as defined in the single Claim.

Claims

Calving device, comprising a support (4) which is mounted on a tube or pole along which a lever mechanism (3) slides, characterised in that the support (5) is curved and hingedly attached to a forked member (6) permitting an upward or a downward traction of the said pole or tube which is mounted on the forked member (6) and the said curved support (5) is shaped in such a way that, in use, it encompasses the whole of the rear end of the animal so that it remains firmly anchored on the animal's rear during traction in any of the above mentioned directions.

Ansprüche

Geburtshilfegerät, bestehend aus einer Stütze (4), die auf ein Rohr oder eine Stange montiert ist, an der sich ein Zugteil (3) entlang bewegt, wobei die Besonderheit darin liegt, dass die Stütze (5) gekrümmt und durch Gelenke mit einen gegabelten Geräteteil (6) verbunden ist, dass Zugbewegungen nach unten und nach oben des besagten Rohres oder der Stange ermöglicht, das oder die auf das gegabelte Geräteteil (6) montiert ist, und die besagte gekrümmte Stütze (5) ist so geformt, dass sie bei der Benutzung die Hinterhand des Tieres umfasst, so dass sie während des Ziehens in jede der oben erwähten Richtungen sicher und fest auf der Hinterhand des Tieres bleibt.

Revendications

Véleuse comprenant un support (4) monté sur un tube ou une perche muni d'un mécanisme à levier (3) coulissant, caractérisée par un support courbé (5) rattaché par des charnières à une partie fourchue (6) permettant d'exercer des tractions aussi bien vers le haut que vers le bas le long du tube ou de la perche. Le support courbé (5) est formé de façon à entourer toute la partie postérieure de l'animal durant l'opération et d'y rester fermement ancré afin de permettre d'exercer les tractions dans les directions mentionnées plus haut.
