UNITED STATES PATENT OFFICE HOG RINGER Clarence L. Austin, Morrison, 111.

Application April 27, 1949, Serial No. 89,828 Claims. (01. 128-332) This invention relates to an improved hog ringer and in particular it relates to a hog ringer having a magazine for the accommodation of a plurality of hog ring blanks.

The principal object of the invention is to provide an improved hog ringer having a magazine between the handles from which a series of hog ring blanks of the so-called Hill pattern may be fed into ring forming position.

Another object of the invention is to provide a hog ringer having improved crimping members which successively cam a ring blank forwardly and downwardly from the plane of the series of ring blanks into a snout-gripping'position, and then form the ring.

A further object of the invention is to provide a hog ringer which may be adjusted to accommodate rings of several different sizes, rings of the Hill pattern normally being furnished in three sizes.

The invention is illustrated in a preferred embodiment in the accompanying drawings, in which- Fig. 1 is a perspective view of the improved hog ringer in position to insert a ring in a hogs snout; Fig. 2 is a bottom plan view of the ringer with its jaws in open position; Fig. 3 is a side elevation similar to Fig. 2; Fig. 4 is a top plan view of the ringer with its jaws in closed position with a fully formed ring in the jaws; Fig. 5 is a bottom n plan view similar to Fig. 4. with the magazine follower plate removed to better illustrate the construction of the ringer; Fig. 6 is a section taken as indicated at line 6-5 of Fig. 4; Fig. '7 is a fragmentary plan view of the inner surface of the magazine follower plate; Fig. 8 is a section taken as indicated on the line 88 of Fig. 3; Fig. 9 is a section similar to Fig. 8 with the crimping members in intermediate position and a ring therein in snout-gripping position; and Fig. ,10 is a section taken as indicated on the line I 0-10 of Fig. 6, showing a fully formed ring in the crimping members.

The hog ringer has a frame containing a magazine to receive a series of hog ring blanks, and a pair of cross-levers is pivotally mounted on the frame with its handles flanking the frame.

with cooperating cam faces which first slide a ring blank downwardly and forwardly into snoutgripping position and then form the ring as the A. follower on the frame is urged forwardly by a A 29, respectively, are a pair of links 30 and 3| handles of the cross-levers are moved together to close the jaws. A cross-head on the frame may have its forward travel adjustably limited and is linked to the cross-levers so as to adjustably limit the opening movement of the jaws, which may thus accommodate ring blanks of several sizes, and a spring urges said cross-head toward its forward position thus tending to keep'the jaws in their adjusted open position.

Referring to the drawings in'greater detail, a frame indicated generally at l l is formed of a channel member so as to have a back [2, and side walls l3 and M which have their lower edge portions turned in, as seen in Figs. 8 to 10. As best seen in Figs. 5, 6 and 9, a guide member I5 is welded to the inside of the hollow, channel-like frame I l at l5a, and extends to the open forward .end thereof. The guide member I5 has a channel-like cross-section generally concentric with that of the frame I I so as to provide a magazine for a series of ring blanks I6. The ring blanks are of the well known Hill pattern, and are preferably held together by a plastic or lacquer coating for easy loading of the magazine. I

A pair of cross-levers l1 and I8 are pivotally mounted on the frame II by means of a rivet IS, the handles and 2| of the cross-levers flank the frame and the jaws 22 and 23 thereof extend forwardly across the open end of the magazine. The jaws 22 and 23 are provided with flanges 24 and 25 which act as stop members for the ring blanks l6. Immediately to the rear of the stops 24 and 25 are crimping cams 26 and 21 (best seen in Figs. 8 and 9) which are positioned to flank the forward ring blank 16a of the series of ring blanks in the magazine. As best seen in Fig. 6 the jaws 22 and 23 and the crimping cams 26 and 21 slant forwardly and downwardly and, as shown in Fig. 8, the crimping cams have long outwardly flaring upper surfaces 26a and 21a, and short inwardly directed lower surfaces 26b and 211). As the jaws close, the shoulders of the forward ring blank Ilia are first gripped between the surfaces 26a. and 21a which slide the ring blank downwardly and forwardly to a snout gripping position (see Fig. 9), at which point the ring blank shoulders are gripped by the lower surfaces 262) and 21b of the crimping cams, and as the .closing of the jaws continues the blank l6a is closed to form a completed ring, as seen in Fig. 10. Pivoted to the cross-levers I1 and I8 at 28 and which have their inner ends pivotally secured to across-head by means of a rivet 33 which extends through a guide slot 34 in the back I2 of the frame I The rear portion of the guide slot 34 is broadened to form shoulders 35.

As best seen in Figs. l to 6, the cross-head 32 includes a main plate 36 which lies above the back l2 of the frame and is provided with a longitudinal slot 360.; and an adjustment plate 3'! which lies beneath the back I2 and has a threaded abutment shoulder 38 projecting through the broad rear portion of the guide slot 34 to contact the main plate 35. A thumb screw 39 extends through the slot 350. and screws into the abutment shoulder 38 to hold the cross-head together. The bottom surface of the main plate and the top of the abutment shoulder are preferably laterally scored to provide good frictional engagement when the thumb screw 39 is tightened. It will be observed that the abutment shoulder 38 engages the shoulders 35 of the guide slot 34 to limit the forward travel of the cros head, and that by moving the adjustment plate 3'! with respect to the main plate 35 the extreme forward motion of the cross-head 32 may be adjusted. By reason of the links 30 and 3|, this in turn adjustably limits the extreme opening of the jaws 22 and 23, so as to accommodate them to ring blanks of several sizes. A U-shaped spring receiver 48 at the rear of the main plate 35 has an arm extending beneath the back it of the frame H, and a tension return spring 4: which extends from said arm to an aperture at the rear of the guide member |5 urges the crosshead 32 to its forward position and the jaws to their open position. Preferably, the adjustment plate 3! is provided with an indicator 42 which projects through the forward part of the guide slot 33 and may be aligned with suitable marks on the main plate 35 to indicate the proper adjusted position for ring blanks of any given size.

A magazine follower 43 has upright sides 44 and 45 and is of appropriate dimensions to slide in the slot formed by the side walls l3 and M of the main frame and the concentric side walls of the guide member l5. The upright sides 44 and 45 of the follower have their forward ends crimped at 46 and 41 to engage the series of ring blanks Hi, and a tension spring 48 is stretched between a hook 49 at the rear of the follower 43 and an aperture in the guide member I5. Thus the spring 48 urges the follower 43 forwardly so as to feed the series of ring blanks l5 successively into position abutting against the stops 24 and 25 of the jaws, and between the crimping-cams 26 and 27. A stop lug so On the inner surface of the follower engages with a lug 5| on the guide member l5 to limit forward motion of the follower; and to facilitate loading the magazine the rear edge portion of the guide member |5 is bent downwardly to form a lip 52 to engage the lug 5i? and retain the follower in a retracted position. The follower makes a loose fit with the slot in which it rides so as to permit the lug 55 to be freed from the lip 52, thus allowing the follower to slide forward after the series of ring blanks I6 is fed into the magazine from between the jaws 22' and 23.

In loading the ringer, the thumb screw 39 is first'loosened and the indicator 42 located in registry with the appropriate mark onthe main plate 36 of the cross-head to adjust the extreme span of the jaws for the particular size of ring blank which is to be used. The thumb screw 35 may then be tightened to lock the cross-head in its adjusted position, and a series of ring blanks l6 may be fed into the magazine between the jaws 22 and 23. As pointed out above, this loading operation is facilitated if the magazine follower 43 is first drawn rearwardly until the lug 59 engages the lip 52 to hold the follower in its retracted position. When the magazine is loaded with a series of ring blanks, the lug 5!) may then be released from the lip 52 and the follower permitted to slide forward to engage the rear ring blank IS in the series and hold the front ring blank |6a against the stops 24 and 25 of the jaws.

The animal to be ringed may be held in any convenient fashion and, as seen in Fig. 1, the ringer may be brought to the necessary position for inserting a ring into the hogs snout. It will be noted that the manipulation of the ringer is very easy because of the fact that the handles 20 and 2| of the cross-levers flank the frame II, and thus are substantially perpendicular to the plane of a ring blank [5, so that the ringer may be brought toward the snout from the side. This is in contrast to the prior art hog ringers in which the handles are substantially parallel to the plane of a ring blank held in the jaws so that it is necessary to approach the hogs snout from above in order to have the ring blank in proper position for ringing. The manipulation of the improved'ringer is far simpler for this reason, and it is easier for the operator to see that he is placing the ring properly in the cartilaginous portion of the snout.

As previously described, as the handles 20 and 2| of the cross-levers are compressed, the front ring blank Hia first is cammed downwardly and forwardly so that its ends project beyond the lower margins of the jaws and are clear of the succeeding ring blank. During the last portion of the closing motion the ring is formed by the crimping cams 25 and 21 and its tips close in a cartilaginous portion of the hogs snout.

When a ringing operation has been completed, the handles may be released, and the tension spring 4|, acting through the cross-head 32, will return the cross levers and H! to their extreme open position. The spring-loaded magazine follower 43 then advances the next succeeding ring blank |6 between the crimping cams 26 and 2'1 and the ringer is ready for another ringing operation.

The foregoing detailed description is given for clearness of understanding only, and no unneces-. sary limitation should be understood therefrom, for some modifications will be obvious to those skilled in the art.
