HOG HOLDERS Filed April 12, 19-54 INVENTOR WILLIAM H. DOOLEY ATTORNEY United States Patent HOG HOLDERS William H. Dooley, Perry, Mo., assignor to H. C. Reynolds, Perry, Mo.

Application April 12, 1954, Serial No. 422,570 4 Claims. Cl. 119-153 My invention relates to hog holders and holders for any kind of animal and by means of which ananimal may be caught and held for the purpose of vaccination or other treatment.

An object of my invention is to provide an improved type of holder wherein the disadvantages of other holders likely to fail has been avoided. More particularly to provide a noose-type of holder that will not jam in its operation.

Other and further objects of my invention will appear from the specification to follow and from an examination of the accompanying drawings, in which: Fig. 1 shows in section the complete hog holder, Fig. 2 shows an enlarged view of the locking mechanism in greater detail, Fig. 3 shows an enlarged sectional end view in perspective of the pivot block along lines 3-3 of Fig. 1 and Fig. 4 shows the pivot block and end-plate in greater detail.

My present invention is an improvement in the conventional type of hog holder now finding wide use by farmers and veterinarians and which consists as shown in Fig. 1, of an elongated metal tube 1, having an end plate 5 secured to the lower end thereof, which end plate 5 has pivoted on one side thereof a cable securing pivot-block 4. End plate 5 and pivot-block 4 constitute the two parts of a hinge. A metal draw-rod 2 extends into tube 1, one end of draw-rod 2 having handle 2a, the other end of the draw-rod having one end of a cable 3 attached thereto and the other end of said cable being secured in the pivot-block 4. In catching and holding an animal the draw-rod 2 is pulled outward from the tube thereby reducing the size of the noose in cable 3 which noose would normally encircle a part of the animal.

Some of the older types of hog holders consist merely of a draw-rod 2 working within a metal tube 1, the end of the cable being secured by welding or otherwise to the tube 1, however the improved types of holders make use of a hinge or pivot for securing the end of the cable and thus avoiding breakage of the cable occasioned by frequent and severe bending at that point. The improved type of holders now finding wide use also make use of a catch, an improvement on which is represented by the reference numeral 6 in Fig. 1 showing my invention and which will be described in more detail later. Heretofore in the art, when one desires to secure the end of the cable in the pivot block 4, it has been by drilling a hole in the pivot-block 4 and securing the end of the cable in the hole by means of sweating in with solder, this being necessary due to the fact that welding the cable to the pivot-block will, because of the heat involved, remove all of the strength of the cable at this point.

It has been found that the use of a round draw-rod permits the cable to be twisted and many times this takes place just at the time the holder is ready to be used. In the excitement that usually accompanies the catching and holding of animals the user can not always pay attention to the precise manner in which he might grasp and pull on the draw-rod to avoid twisting of the cable at the "ice noose. I have avoided this twisting by making use of a rod having a cross-section other than round, reference numeral 2 in Fig. 2 showing it to be square. Means are then provided to prevent the rod from turning within the tube and it is shown in Fig. 2 how this may be accomplished by means of a guide shaped similar to the crosssection of the rod, the guide shown being a square hole in extension 6a of locking mechanism 6.

In the usual type of holder finding wide use the end of the cable 3 is swetted into the pivot-block 4 as previously mentioned. I find that instead of entering the pivotblock 4 at the end thereof, it is preferable to enter the pivot-block 4 with the end of the cable on one side of the pivot-block 4 rather than at the end. In so doing it is possible for the terminated end of the cable to line up exactly with the open end of the metal tube 2while if the end of the cable is secured to the end of the pivotblock 4 instead, there will be a sharp bend of the cable when it is completely drawn all the way into the tube, and this bend will occur at the weakest part of the cable, namely where it joins the pivot-block 4. I also find it desirable to allow the end of the cable to rotate within the pivot-block 4 and this is shown more particularly in Fig. 3. Here it will be observed that the pivot-block 4 is shown in section, the section line being at the securing hole. The hole is slightly larger than the size of the cable being used and axial movement of the cable through the hole is restricted by stops 10 and 11 shown as washers which have been swetted on the cable at the places where the cable emerges from the pivot-block 4. These stops 10 and 11 constitute a bearing for cable 3 on both sides of pivot-block 4.

Cable 3 is usually made of highly resilient or tempered strands of wire which are twisted tightly. The cable will normally seek to return to the same position it was in before it was flexed, the flexing in our case being when the noose is lightened or loosened. It is important to permit this normal movement of the cable 3 to avoid kinks and twists in the cable, particularly at the noose portion.

We will now examine the catch or locking mechanism 6 in more detail. Fig. 2 shows a piece of flat metal which is bent at an angle greater than degrees constituting an extension 6a. It will be observed that extension 6a has a square hole through which the square crosssectioned rod 2 passes. The size of this hole in extension 6a is made larger than the width of rod 2 so that when the plane of extension 6a is perpendicular to the axis of rod 2 the rod will slide easily through the hole. It will be observed that the main elongated portion of the flat metal piece has a hole 7a through the same and through which a pin 7 extends. Pin 7 is fastened to tube 1 and serves as a pivot into which the elongated piece is secured from appreciable movement in any particular direction although the elongated piece is free to rock up and down. The hole in extension 6a is small enough to prevent the assembly 8 from separating from pin 7. It is clear that side movement or appreciable rotation around the axis of pin 7 is prevented because the draw-rod 2 can only move to the inside surfaces of tube 1.

Fig. 4 shows a preferred way to secure the end-plate 5 and pivot-block 4 in pivotal relation. The pivot-block 4 is normally provided with a hole 4:: extending on either side in one direction into which the bearing in end-plate 5 takes place. In a plane perpendicular to that of hole 4a I provide another hole 9 into which the end of the cable is secured. End-plate 5 has two lips shown as 5a and 5b shown as open in Fig. 4 and in closed position in Fig. l.

Lips

5a and 5b are pressed into hole 4a and constitute in the assembled device a satisfactory pivot. Hole 50 is for mounting the end-plate 5 on the tube 1.
