. 8 Claims. 1

This application-is a 'continuation in-part of my application Serial No. 493,069, filed July 1, 1943.

The present invention relates to an improved stock handling apparatus especially adaptedfor handling calves, although the same may be employed for use with other livestock. It is a general obj ect of the present invention to provide an improved stock handling apparatus by means of which a calf or other animal may be firmly secured and supported in a convenient position for the performance of the various operations customarily performed upon livestock, such as branding, inoculating, castrating, de-horning and the like, the animal being supported out of contact with the ground whereby danger. of infection is reduced and the convenience of the operators is promoted, while at the same time the number of men required to perform the various operations is reduced due to the'fact that theanimal is secured in position by mechanical means.

A further object is the provision of a stock handling device of the characterdescribed in which, by a single-operation, the'animal is securely clamped against a swinging table while the latter is in generally vertical position and, as the pressure upon the animal becomes suflicient to secure it in place, continued effort applied to the securing means results intilting the table into operative position, the securing vor clamping means being at the same time automatically held in position inrespect to the table.

A further object is the provision of a device of the character described comprising generally a supporting base, a swingable table mounted thereon, and a clamp'member spaced from but pivotally mounted-on or adjacent the-lower edge of the swingable table by means of hinges which are adjustable in length, whereby'the spacing of the clamp member from the table may be varied to accommodate animals of differentsizes, and whereby, likewise, the spacing of-the' clamp member from the table may be varied at its respective ends, so that at the centering end of'the device the clamp member maybe spaced further from the table than at the opposite end whereby a funnel-like effectis achieved.

A further object isthe provision of a device of the characterdescribed-in which means are provided for engaging the back of an animal :toprevent the latter from jumping or moving upwardly in the device before being securely clamped therein, saidback engaging-means being adjustable-in, height for the accommodation-of animals of different sizes.

A further object is the provisionof a device of the character described comprising an animal supporting platform secured to and swingable with the table, said: platform being in horizontal position when the table is in generally vertical position as when an animal first enters the device, the clamp member being so pivoted relative to the table that as the animal is clamped against the table its feet are removed from the supportfrag-platform whereby the animal is prevented from exerting effort againstthe platform and is thus more firmly secured between the clamp member and the table.

A- further object is the provision of a device of the character described in which the clamp them-- her is of lesser dimensions longitudinally than the swingable table whereby, when the deviceis tilted into operating position, the head of an animal clamped therein is freely accessible from above for de-horning, or other operations.

A further object is the provision of a device of the character described in which the clamp mem ber -is provided with a swingable portion, normally lying substantially in the plane of the clamp member but which maybe lifted after the device is tilted into operative position for'the purpose of exposing the rearward portion of the animals body to permit the performance thereon of such operations as are desirable.

'Other and further objects, features and advantages will be apparent from the description which follows, read in connection with the accompany-'- ing drawings in which Figure 1 is a perspective view of the stock handling device;

Figure 2 is a top plan view of the device of Figure 1;

Figure 3 is a side elevation of the device of Figures 1 and 2;

Figure 4 is a vertical section on line '4-4'of Figure'3;

Figure 5 is a'partial side elevatiomseen from the side opposite that seen in Figure 3;

Figure 6 isa horizontal section'on line'6-6 of Figure 5;

Figure '7 is a horizontal section'on line 1-1 of Figure 3; and 1 Figure 8 is a perspective view of a neck holding bar employed with the device of Figures 1 to 7.

In order tofacilitate an understanding of the invention, reference is made to the embodiment thereof shown in the accompanying drawings, and detailed descriptive language is employed; It will nevertheless be understood that no limitation of the'invention is thereby intendedtand 3 that various changes and alterations are contemplated such as would ordinarily occur to one skilled in the art to which the invention relates.

Referring now to Figures 1 and 2 it will be seen that the device comprises a generally rectangular base consisting of transverse members I and II and longitudinal members I2 and I3, which may be conveniently formed of tubing connected by welding or other suitable means but may be of any suitable material and construction. Preferably the base structure is supported above the ground by pads I4 welded thereto, and each of the transverse members II] and I I is provided with an aperture I5, IE to receive anchoring devices such as spikes whereby the structure may be secured in place. Transverse member I0 is provided with a generally vertical post or support member I! and transverse member II is provided with a similar support member I8, the vertical supports being preferably secured to the transverse members by welding. Transverse member II is provided with a second support member |9 permanently secured thereto and which inclines outwardly opposite to the inclination of the support I8 (forming a V-like opening therebetween. Transverse member ID is similarly provided with a detachable support member 20, which may be threaded into a boss 2| formed on the .transverse member I I), and which likewise forms with the support I I a V-like opening therebetween. For reasons hereinafter explained, the support may be dispensed with in certain circumstances.

' Referring now to Figure 4 is will be seen that the base structure comprises, further, a longitudinal member 22 extending between the supports l1 and I8, vertical members 23 rising from either transverse member I 9, II and longitudinal member 24 extending between the vertical members 23. Each vertical member 23 is connected at its upper end with the adjacent support member I7, I8 by a horizontal transverse member 25. The longitudinal member 24 is provided, centrally, with a projection 26 which serves as one portion of a latching device as hereinafter described.

The support member I8 is provided near its upper end with an eye 21 while the support I1 is provided near its upper end with an outwardly and upwardly extending projection 28 forming with the support I I a U-shaped socket, such socket and the eye 21 being adapted, respectively, to receive

trunnions

29 and 30 by which a tilting table 3| is supported upon the members I1 and I8. For purposes of transport the table and associated mechanism may be easily and quickly removed from the base structure, and the two parts handled separately.

The table 3| comprises a framework preferably constructed of tubular material and consisting of

horizontal members

32, 33 and 34 connected by vertical members 35 to 42, inclusive (Figure 5). Said framework is preferably provided on its inner surface with a cover 43 Off sheet metal except for the portion 44 which is left open. Horizontal members 45 extend across the open portion 44 of the table 3| and provide stop means for the back engaging member to be later described. An animal supporting platform'46 is rigidly secured to the lower edge of the table 3| and extends laterally therefrom in a plane parallel to the ground when the table 3| is in its generally vertical position.

For cooperation with the tiltable table 3| a clamping member 50, which comprises vertical members 5|, 52 and 53 connected by

horizontal members

54, 55, 5B and 51, is hingedly secured to and supported upon the lowermost horizontal member 32 of the table 3|. As best seen in Figure 7, the hinges 58 are rigidly secured to the horizontal member 51 of the clamp, and are pivoted upon the horizontal member 32 of the table. The hinges 58 are adjustable in length, being constructed in two parts connected by bolts 59, one or both of the parts being provided with a plurality of apertures to receive said bolts. In this manner, the spacing of .the clamp from the table may be varied to accommodate larger or smaller animals. Further, as illustrated in Figure 7, the clamp may be spaced further from the table at the entering end of the device than at the opposite end, thereby creating a funnel-like eiTect whereby the animal becomes jammed in the device as it moves forwardly therein.

A gate 60 may be employed if desired, the gate being mounted in any suitable manner upon the support 20 and being adapted to be secured-by means of a loop 6| to the support I! when in closed position.- However, it has been found that when the spacing of the clamp from the table is adjusted as illustrated in Figure 7. so that the animal becomes jammed between the clamp and table as it progresses forwardly therebetween, the gate 68 may be dispensed with and .the support 20 may be detached from the device and temporarily discarded.

The lower portion of the clamp 58 is preferably provided onits inner surface with a covering 82 of sheet metal which serves to prevent the animal from attempting egress between the several frame members. At the entering end of the device, the clamp 50 is provided with a swingable flap portion 63, pivoted at 64 upon vertical members 5| and 52, respectively, which flap portion likewise serves as a screen while the animal is entering the device, but may be raised after the device is tilted to operative position for the purpose of performing any desired operations upon the rearward portion of the animal. The lower edge of the flap portion 63 is provided with a stop member 66 which abuts against the adjacent verticals 5| and 52. a

A back engaging device 61, comprising a longitudinal member 68 and

transverse members

69, 18, II and I2, is adjustably mounted upon the vertical members 5|, 52 and 53 of the clamp 5|! by means of bolted clips I3, and serves to prevent an animal entering the device from jumping up wardly and becoming displaced as the clamp is tightened upon him. In order to prevent the transverse members of the back engaging device from being bent upwardly by the animal, they are arranged to project through the space between the horizontal members 45 of the table, which thus serve as stops for the upward movement of the back engaging device caused by contact with the animal. When the back engaging device is in its highest position the top horizontal member 34 of the table serves as such stop means.

The clamp 50 is adapted to be moved toward the table 3| by me'ans'of a rack bar I4 which is provided with a handle 15 (Figure 4) for this purpose; The teeth of the rack bar cooperate with a latch I6 (Figure 6) which is pressed against the bar by means of a spring II retained in a barrel 18 secured to the top of the table 3|, the rack bar extending through a suitable aperture formed in the barrel I8. The latch I6 may be retracted by means of a lever I9 which is connected to the latch by means of a link 80.

The central vertical member 3'! of the table 3| is provided with aspring latch device 81. for

engagement with the projection "26 (Figure 4) when the table is tiltedto operative position, thus holding the table in such position, in which i and the animal. held thereon are in substantially horizontalposition. resting upon the horizontal member 24. The latch-8i maybe retracted by means of the-handle 82.

At times it is des rableto employ means for holding the animals neck tightly against the tableSI, and for-this purpose the neckholdingxbar 83 of Figure 8 isprovided. apertures being formed. in. the table for cooperation with the bar'83.

From'the foregoing description it is believed that-the operation of the device will be readily understood, The-device is :placed with-its. enter ving end'adiacent the exit end of a corral chute.

from which the animals may be driven one by" one into the entering end of vthe'devicc. As an animal enters the device and standsupon the platform it an operator grasps the handle IS-and pulls theclamp Wtoward'the table 3!. The device is so balanced and proportioned that as the 1 pressure upon the-animal becomes sufficient to secure him firmly'between the clamp and table, the table is'tilted until it is-substantially horizontal when it is latched in position by the spring latch :8! as just described. Meanwhile, the relationbetween the clamp and the table'is main tained by cooperation between therack bar"! and thelatchlfi. .As the clamp is pulledtoward the table, and duelto the fact that the hinges 58 are pivoted on or adjacent the lower edge of the table, the lower edgeof the clamp rises above ,the platform 46, thus lifting the animal slightly so that its feet are no longer in contact with the platform, and thus serves to completely immobilize the animal.

If desired, the end 85 of the neck bar-83mm be inserted in one ofthe apertures 84 of the table and the. neck of the. animal clamped byiexertins pressure upon the free end of the necklbar, the rockers 86, welded to the bar 83, serving as stop members to prevent the bar from penetrating too far through the aperture 84 and also serving as rocking pivots or bearings for the bar, the surface of the table adjacent the aperture 84 serving as a fulcrum. The offset portion 81 of the bar fits over the animals neck.

As will be readily appreciated the head of the animal is entirely accessible from above, for dehorning, or branding, or the like, while the rearward portion of the animal is accessible by lifting the flap 63, for inoculation, castration, or other operations.

When all desired operations have been performed, an operator simultaneously releases the

latches

16 and 8|, by means of the

handles

19 and 82, respectively, whereupon the table reverts to vertical position and the clamp 50 is retracted, freeing the animal to move forwardly out of the device.
