Abstract
ABSTRACT OF THE DISCLOSURE
An animal control mechanism in an animal passageway such as a race comprises a control member rotatably mounted about an elevated horizontal axis between the sides of the passageway. The control member has a number of limbs and is uni-directionally rotatable to bring a limb down behind an animal passing underneath and thereby prevent its return along the passageway.

This invention relates to animal handliny equipment, and has as an object to provide a mechanism to assist in controlling animals passing along a pa~sageway.
According to one broad aspect, the invention relates to an animal control mechanism for controlling the movement of animals through a passageway, compr:ising a control member rotatable about a horizontal axis extending transversely between the sides of the passageway at a height to allow the animal to pass under the axis, the control member comprising a plurality of limbs extending from the axis so that on xotation of the control member successive limbs pass through a depending position in the path of animal~ passing along the passageway, means for restricting the rotation so that an animal can pass the control mechanism in one direction on rotation of the !~
control member but be prevented from ret~ning by ~he Ij;
obstruction of a depending limb of the member, each limb of the cojntrol member having a pair of side frames which are divergent in the direction of advance of the limb so that the side frames of a depending limb wedge onto the rump of an animal and thereby centrally locate it.
The control member may be adapted or unidirectional rotation by means of a pawl and ratchet device. This device may be releasable to allow rotation in either direction should the occasion arise.
The mechanism preferably includes means for manually rotating the control member. This may for example comprise a cranked handle, a lever or a wheel.

Fig, 3 shows a cross-sectional plan view on the line III-III of Fig.-2, Fig. 4 shows a perspective view of a third ~orm of control member, and Fig. 5 shows a diagrammatic plan view of the control member of Fig. 4 in use.
Referring to Fig. 1 of the drawings; the cattle handling unit comprises a parallel-sided race made up ~rom hurdles 10 interconnected through an intermediate arch member 12. At the end of the race is arranged a crush gate 14 for trapping the,neck of an animal in the race.
An animal control mechanism is provided in the end part of the race, at a distance from the crush gate which roughly coincides with the rear end of an animal whose head , ' ' is through the crush gate. The mechanism has a control member 15 comprising a pair o~ opposite limbs 18 of tubular steel frame construction and a central axle 20 by means of which it is rotatably mounted to bars 22 clamped to the top rails of the two hurdles forming that part o~ the race. The positions of the bars 22 can be adjusted along the hurdles, and the height can be varied by clamping them onto lower bars of the hurdles. A pawl 24 on one of the bars 22 co-operates with a ratchet 26 on the axle 20 to allow rotation of the ' control member only in one direction (as indicated by the arrow 'A'). Rotation can be effected manually by means of a ,,~ ~
wheel 28 which can be mounted directly on the end of the axle ' 20, but, in the embodiment shown, is rotatably mounted alongside the axle 20 and connected therewith by a chain 29 trained around sprockets 31j33 on the axle 20 and the wheel 28 respectively, to effect a reduction gearing in the .. , .. . ,. ............... , j .

transmission between the ~heel and control member. The pawl can be lifted, if desired, by means of a handle 21.
In operation, the animals are driven down the race, and when the first animal reaches the control mechanism an operator rotates the wheel 28 to bring the limbs 18 to -the horizontal position thus allowing the animal to pass under the axle to~ards the crush gate. As the animal passes, the operator rotates the handle further, bringing a limb 18 down behind the animal, thus preventing any rearward movement by the animal. ~en the animal has been dealt with and released from the crush gate, the wheel 28 is rotated and the next animal allowed through. If desired at any time, ths pa~l 24 can be lifted to allow the wheel to be rotated in the other direction.
As an additional and desirable feature, a~ shown in Fig. 1, a freely rotatable transverse roller 30 may be -provided at the end of each limb 18, rather than a fixed transverse bar. l!~en the animal walks under the horizontal ~ ;

animal. Furthermore, Fig. 1 shows how the transverse bar at each end of the control member may be adjustably mounted to the side frames of the control member so as to be movable towards and away from the axle 20 to vary the effective length of each limb. Rods 19 at each end of the transverse member are slidable in tubular side frame members 17. The rods have a number of apertures which can be selectively en~aged by pins 15 or the like removably extending through apertures in the side frame members.

of ~ig. 1. The side frames incorporate additional frame elements to assist in locating against the rump o~ the animal being controlled. Each :limb of the contro~ member has a pair of forwardly projecting frame elements 40 and a pair of rea~ardly projecting frame elements 42. The frame elements 40 are slightly divergent and the frame elements 42 are appreciably convergent, as is clearly seen in Fig. 3.
The depending limb of the control member can thus locate better against the rump 44 of an animal, and can accommodate animals of different sizes. This can be further facilitated by making the side frame members pivotable about the longitudinal axis of the frame member 17. The amount of pivot1ng can be limited to about 10 or 15 , and allows the side frames to adjust automatically to the different ~izes and shapes of rump which occur in, for example, cows.
The animal's rump becomes lightly wedged between the side frames, and is then more securely located.
Figs. 4 and 5 show an alternative form of control member, having essentially the same functional ~eatures as the control member of ~igs. 2 and 3. A pair of parallel generally rectangular side frames 46 each have a central longitudinal frame member 48 between which extend the central axle 20 and the rotatable transverse end members 30. The transverse members ~0 are joined to their respective frame member~ 48 through rod~ 19, as in the previous embodiments~ so that they can be adjusted. The side frames 46 are mounted to the frame members 48 by rotatable collars 50 so as to be pivo-table over a limited range of movement to locate against the rump 44 of the animal, as shown in Fig. 5. Fig. 5 also :

shows -that -the side frames 46 need not be planar, but can be angled about the central frame rnernbers 43 to provide a better fit against the rump of -the animal, The mechanism of the present invention can be mounted in the entrance or exit or both of animal handling crates or animal weighing crates to control the entry and/or exit of animals. Instead of a pawl and ratchet, the control member could be locked by ~ her means, for example a removable pin inserted in a sl~t in a fixed part of the struc-ture so as to engage the control member and either prevent or limit i-ts rotation~
