Newbold, Cedar Rapids, Iowa Application September 18, 1943, Serial No. 502,995 3 Claims. (01. 119—-98) 1 This invention relates to a trap for catching and holding hogs for ringing, castrating or other purposes to which it may be adapted. It is the object of my invention to provide a de vice of simple and inexpensive construction that 2 at 33 by a twin turnbuckle arrangement 34 that permits adjustments of the master holding mem bers H—l2. The pedal 15 is held in any posi tion desired by a ratchet member 35 held against bolt 36 by spring 31 and. released by handle 38. The‘master holding members ll-IZ are re will catch and hold a hog without injury and with turned to open position by withdrawing springs minimum effort of the operator. 30 attached at 39 and 40. As a precaution against Another object of my invention is to provide a damage to rope 14 by the hog’s hoofs as it proceeds device that will permit the hog to pass freely 10 through the trap after being released a protect through the trap after being released. ing bar it! is engaged to the right master holding Other and further features and objects of the member l2 at 42 and passes freely through left invention will be more apparent to those skilled holding bar II at opening 43. _ in the art upon a consideration of the accompany Referring now again to Figure 3, the operating ing drawing and following speci?cation, wherein is disclosed a single exemplary embodiment of the 15 rope I3 is placed through the turnbuckle 34 and knotted at the correct distance from each end. invention, with the understanding, however, that One end is placed over pulley 29, through large such changes may be made therein as fall within opening in right member I2 at 44 and engaged the scope of the appended claims, without de to left member H at 45. The other end of rope I3 parting from the spirit of the invention. is placed over pulley 28 thence downward over Figure l is a front view of my device in open 20 pulley 2? then through member l2 at 46 and en position and showing the foot operating pedal in gaged to left member I I at 41. Rope I4’ is placed through the other turn buckle at 34 and likewise knotted at the proper distance from each end. One end is placed over 25 pulley 29, then through member l2 at M ‘thence eral. Figure 3 is a cutaway View, showing the operat around pulley 26 and engaged to member I2 at ing mechanism and illustrating in particular; the 4B. The other end of rope H5 is placed over pulley location of the pulleys. 28 thence downward over pulley 21, through mem Figure 4 is a side View of the right holding ber l2 at 46, around pulley 25 and engaged to 30 member showing the upper and lower positions of member l2 at 49. the openings through which the operating ropes I have referred to l3 and 14 as operating ropes pass. and preferably use this type of connection, how Referring now to the drawing a preferred em ever, it is understood that cables, chains, or other bodiment of my invention includes a frame indi place for downward movement. , Figure 2 is a front view showing the device in closed position and the frame members in gen may be used. cated generally at H], trapping members |I--l2, 35 means In use, as the hog’s head enters the space be cooperating ropes I3—lli, and pedal E5. tween the holding members, the operator pushes The frame If! is composed of two horizontal down on the pedal 15 which causes members parallel lower members ll, two horizontal parallel i l—l 2 to move toward and against the hog’s neck upper members 18, diagonal upright converging at equal speed and pressure. As the desired tight side members 19, perpendicular upright members 40 ness is obtained, the ratchet arm member 35 holds 2!! and horizontal braces 2!.

The trapping element consists generally of two To release the hog, the operator again pushes. master members I l-l2 movable horizontally be tween parallel upper and lower frame members 45 down on pedal l5 and grasps handle 38. This re leases ratchet arm 35 from holding bolt 36 caus I'l--l8, suspending blocks 23 and ascension stops ing springs 39 to return members H-—l2 to open 24. The holding members H——i2 are shaped to properly fit the hog’s neck and are operated by the action of ropes |3—l4 placed over pulleys 25, 26, 21, 28, 29, withdrawing springs 30 and coop erating pedal l5. The pedal 15 is engaged to the lower frame member I‘! by a hinge 3| and ex tends through a guide formed by an auxiliary position, permitting the hog to pass through with out injury. The trap may be attached to a chute and be come an integral part of it or it may be placed in a door or runway, whichever is desired. 60 H I claim as my invention: 1. In a hog trap, the combination of a pair of diagonal frame member 32.
