United States Patent Office 3,292,590 Patented Dec. 20, 1966 3,292,590 SHEEP HOLDING DEVICE James L. Powell, Elder-ado, Tex. (Box 7, Fort McKavett, Tex. 76841) Filed Dec. 22, 1964, Ser. No. 420,298 2 Claims. (Cl. 119-103) This invention generally relates to new and useful improvements in holding devices particularly although not necessarily for sheep and has for its primary object to provide, in a manner as hereinafter set forth, novel means for gently but firmly securing the animal in a position and at an elevation to facilitate marking said animal or performing surgery thereon.

Another highly important object of the present invention is to provide a sheep holding device of the aforementioned character which embodies unique means for releasing the animal and returning it to the ground.

Still another important object is to provide an improved holding device of the character described which will accommodate several animals simultaneously thus greatly speeding up the work when a large number of animals are to be treated.

Other objects are to provide asheep, etc. holding device of the character set forth which is comparatively simple in construction, strong, durable, compact, of light weight, portable and which may be manufactured at low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a view in front elevation of a sheep holding device constructed in accordance with the present invention;

FIGURE 2 is a view in side elevation thereof;

FIGURE 3 is a vertical sectional view through the device, showing said device in use; and

FIGURE 4 is a perspective view of one of the trays or cradles.

Referring now to the drawing in detail, it will be seen that the embodiment of the present invention which has been illustrated comprises a supporting frame or table of suitable tubular metal which is designated generally by reference numeral 6. The frame 6, which also may be of any desired dimensions, is elongated and said frame, in the embodiment shown, includes a pair of front legs 8 and a pair of relatively long, upwardly and forwardly inclined rear legs 10. A horizontal front brace 12 extends between intermediate portions of the legs 8. A substantially similar brace 14 extends between intermediate portions of the rear legs 10. Side or end braces 16 connect the front and

rear legs

8 and 10. The braces 16 are adjacent to but spaced below the upper ends of the

legs

8 and 10. Forwardly and downwardly inclined top braces 18 extend between the upper ends of the

legs

8 and 10. Then, a top brace or bar 20 extends between the upper ends of the rear legs 10.

Extending between the upper portions of the front legs 8 of the frame 6 is a rod or shaft 22. Substantially trough-shaped trays or cradles 14 are mounted for vertical swinging movement on the shaft 22. Each cradle 24 includes a trough which is open at both ends and which includes a bottom 26 and side walls 28. The front end of the bottom 26 is recessed, as indicated at 30.

The side walls 28 comprise outturned segmental flanges 32. Depending arms 34 are afiixed to the forward end portion of the cradle 24 at right angles thereto. The arms 34 are affixed to the side walls 28. Aflixed to the lower ends of the arms 34 is a tube or sleeve 36 which is journaled for rotation on the shaft 22.

Each cradle 24 is provided with a spring biased clamp 38 for securing a sheep or other animal, as indicated at 40, in said cradle. As shown, the animal 40 is placed on its back in the cradle 24. The clamp 38 includes an elongated generally U-sha-pcd frame 42 which engages the animal longitudinally and is straddled by the upstanding front and hind legs of said animal. The legs 44 of the generally U-shaped frame 42 include downwardly right angularly bent end portions 46 having afiixed to their ends a tubular bearing or sleeve 48. The sleeve 48 is journaled for rotation on a rod or shaft 50 which extends between intermediate portions of the arms 34 of the cradle 24. Openings 52 in the arms 34 receive the end portions of the rod or shaft 50.

A downwardly extending arm 54 is afiixed to the sleeve 36. As shown to advantage in FIGURE 3 of the drawing, the arm 54 is adapted to abut the brace 12 of the frame structure 6. Aflixed to the sleeve 50 is a downwardly and forwardly extending lever 56. A coil spring 58 is connected to the arm 54 and the lever 56 for yieldingly urging the frame 42 toward clamping position. A yoke or the like 68 is mounted transversely on the forward portion of the frame 42. A pull rod 70 is pivotally connected to the yoke 68 for swinging the frame 42 upwardly against the action of the spring 58,

It will be noted that in the embodiment which has been.

illustrated three of the cradles 24 with the clamps 38 have been shown on the frame structure 6. The free end portions of the cradles 24 normally rest by gravity on the top brace 20 of the frame structure. Reference numeral 72 designates instruments supporting shelves which are removably mounted on the ends of the frame structure 8.

It is thought that the use or operation of the device will be readily apparent from a consideration of the foregoing. Briefly, with the clamp 38 in raised or open position, the animal is placed on its back in the cradle 24 with its head uppermost, as shown. In this connection it will be observed that the construction and arrangement is such that the trough-shaped cradle 24 is forwardly and upwardly inclined. Under the influence of the spring 58, the elongated, generally U-shaped frame 42 of the clamp 38 is engaged longitudinally with the animal between its front and hind legs for firmly holding said animal in the cradle in a position to facilitate the work to be done. It also Will be noted that the clamp 38 is swingable independently of the cradle 24. When the work has been completed the cradle 24 is swung upwardly, rearwardly and then downwardly on the frame structure 6 for lowering the animal to the ground in a substantially upright position from which it may leave the holder without difficulty. Of course, the supporting frame or stand 6 may be of a size to accommodate any desired number of the cradles 24.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:
