11 Claims. 1

My present invention relates to hog ringers of the general type disclosed in the application of Sylvester P, Callaway, Serial No. 31,153, filed June 4, 1948, now Patent #2,466,928, issued March 3, 1949, and comprises various improvements on the structure disclosed in said application. Among the objects of this invention are the provision of a hog ringer of the general type indicated which will to a greater extent be automatic in its operation than the machine of the application referred to above; the provision of a machine of the type indicated which will, when placed against the nose of a hog, automatically apply a ring to the hogs nose and then open up to release a ring and permit the hog to move away freely from the position occupied by him when the ring is being applied; the provision of a ringer of the type indicated having means for adjusting the size thereof to fit rings of difierent sizes; and such further objects, advantages, and capabilities as will hereafter appear and as are inherent in the construction disclosed herein. My invention further resides in the combination, construction, and arrangement of parts illustrated in the accompanying drawings and, while I have shown therein what is now regarded as the preferred embodiment. of this invention, together with a modification thereof, I desire the same to be understood as illustrative only and not to be interpreted in a limiting sense.

In the drawings annexed hereto and forming. a part hereof:

Fig. 7 is a. perspective view of the ring feeder,

Shown in elevation in Fig". 5;

Fig. 8 is a side elevation of the operative mechanism of a modified form of construction in which the rings are fed manually and individ ually to the ring-closing jaws;

Fig. 9 is a front elevation of the structure shown in Fig. 8, and

Fig. 10 is a fragmentary side elevation of the rear portion of the mechanism shown in Fig. 8, the same being shown in a partially perspective position.

As shown in Figs. 1, 2, and 3, a housing I I, which contains the mechanism, has a handle ['2 at one end and a finger opening 13 defining the handle. An opening i l extends along an edge of the housing H for the passage of the cocking handle l5. The handle is connected to a lug It by a pivot ll.

A pair of pivot posts 3! is mounted in the housing H in the forward part thereof. Each post '31 has pivoted thereon a bifurcated member 51.

which members are held in adjusted position by a left and right hand thumb screw 54 which is threaded into the connecting web 56 of each of said members iii.

A pair of ring-holding jaws. 38 is pivoted, individually, on pivot posts 37. A pair of operating levers 35 is also pivoted, individually, on posts 31. Levers 35 have forward ends 52 which are engageable in channels in jaws 38 for moving the jaws together. The rearward ends of the levers 36 are connected, individually, to toggle arms I9, 29 which are interconnected by pivot 5'8. Pivot i8 is movable in longitudinal guide slot I la in the housing 6 Pivot 18 carries a roller 2! and a spring connector 33 mounted thereon. Springs 3 engage connector and are anchored on pins 35 near the forward end of the housing. The pivot i8 is engageable by the cocking handle 55 upon rearward movement of the latter, whereby to move the pivot i8 rearwardly.

A hook 22,. engageable with the pivot I E! in rearward position thereof, is mounted on post 23 for rotation, and. is biased into hooked position by spring 24 anchored on pin E la carried by boss 25 in the housing ll. An arm 25 is fixed for movement with hook 22. A pin 23 is mounted in the housing for engaging arm and thereby limiting movement of hook 22 into hooked position. An operating rod 27. is pivoted to arm 25 and has a s eeve 3! secured at its forward end. A rod 29 is held in adjusted position in sleeve 3! by set screw 38. The rod 29 has its tor -yard end bent laterally to a position between the ringholding jaws 38.

In operation, when rod 29' is moved rearwardly by the septum of an animal, the hook 22 releases the pivot |8 for motion by the springs 34. The toggle then moves the jaws 38 together until pivot I8 is between the pivotal connections of arms l9 and 20 and the levers 38. Continued motion of pivot l8 in the slot Ila moves the forward ends 52 of the levers 38 apart. This provides immediate release of the ring after closure. The device may then be recocked by rearward motion of the arm |5.

One arm of each bifurcated member 51 is extended forwardly and carries an angular guide 42 for a ring magazine. The guides 42 are facing and the distance between them may be adjusted by thumb screw 54 for carrying various sized rings. As shown in Figs. 5 and '7, a spring follower is employed which comprises a frame 5| having three parallel arms. A follower bar 50 is slidable n the three arms and is biased toward the free ends of the arms by the spring 49 which is secured at its ends to bar 59 at its center and to the free end of the center arm. The spring follower may be held in position between the guides 42 as by hooks illustrated in Fig.

To load the magazine, rings are placed between the guides 42. The spring follower is then hooked in position with the follower bar 59 pressing against the rings. The jaws 38, in normal position, close the lower ends of the guides 42 and prevent passage of rings. The facing surfaces of jaws 38 are provided with channels 39 for the reception of rings from the guides 42. The jaws 38 on the sides of the channels 39 away from the guides 42 are provided with extensions 48 to stop rings in the plane of channels 39 when received from the guides 42. The channels 39 are curved toward each other at their forward ends to provide stops 4| to hold a ring in position 32 ready for application.

The following mechanism is provided for opening the jaws 38 and formoving rings in the channels 39 forwardly. A rectangular frame, which comprises the bars 44 and crossbar H, is slidably mounted in the housing on pin 14 which is received in slot in crossbar 1|. The frame is biased to forward position b the tension spring 12 which is connected to the crossbar 1i and to the pivot 23. The forward ends of bars 44 are connected to extensions 56 on the jaws 38 by pivots 45. Rearward motion of the frame opens the jaws 38, thereby to allow passage of one ring onto extensions 48.

A link 62 is connected at one end to handle 15 by pivot 8|. The link 62 is connected at its other end to one end of the link 84 by the pivot 53. The link 64 is connected at its other end to a boss 58, integral with the housing H by the pivot 65. An arm 59 is mounted on the post 23 for free rotation thereon. The free end of the arm 59 has connected thereto a tension spring 67 which, in turn, is connected to the pivot 65. In normal position, the spring 61 will bias the arm 59 to a position between the post 23 and the pivot 65. From this position, the arm 59 may be moved in either direction. The pivot 83 is extended to the plane of the arm 59 whereby to engage the arm 59 and move it in either direction. An adjustable abutment 79 is mounted in the crossbar ll for engagement by the arm 59. Rearward movement of the handle l5 moves the pivot 83 rearwardly and, in turn, the arm 59 which, by engaging the abutment, moves the frame rearwardly until the pivot 53 slips past the end of the arm 59. The spring 12 then moves the frame to forward position.

The rod 58 is connected at its rear end to the arm 59 by the pivot 69. The forward end of the rod 58 is turned laterally to a point between the jaws 38 and terminates in a ring-engaging head 49 which is grooved in its front face to receive a ring.

In operation, the rod 29, as shown in Fig. 3, is engaged with the septum of an animal,whereby to move the rod 23 to the rear. This unhooks the toggle and pivots the arms 35 under action of the springs 34. The jaws 39 are closed by the levers 36 and close ring 32 on the septum. Completion of spring operation of the toggle releases the jaws 38, whereb the animal is immediately released.

The handle I5 is then moved rearwardly and engages the pivot l8 and moves it rearwardly, as above described, to cocked position. At the end of this rearward movement, the pivot 53 moves the frame to the rear and opens the jaws 38. Simultaneously, the rod 58 is moved to the rear. With the jaws open and the head 48 to the rear, another ring drops into the jaws. The handle i5 is then moved forward. The pivot 53 then moves the rod 58 forwardly, whereby the ring is moved forwardly. Upon completion of the forward motion of the handle i5, the arm 59 is freed from engagement with the pivot 63. Therefore, the arm 59 returns to normal position. The ringer is then again in loaded operating position.

In the form of Figs. 8 to 10, the upper lever and upper jaw 77 are constructed to move as a unit, although structurally, they may be separate. The lower lever 36 is formed of spaced apart laminae, between which there is mounted a stop 8| for reciprocation. The lower jaw Ila extends in both directions from its pivot 31, with the rear arm thereof between the laminae of the lever 35. The stop 8| has a shoulder on its forward side for engaging the rear end of the jaw Ila for moving the jaw to closed position. To operate the stop Bl, an extension 19 is provided on the toggle arm 28 which supports a pivoted guide 85. A rod 82 has a knob on one end, extends through the guide 85, and is pivoted to the stop 8|. Springs 83 and 84 are positioned on the rod 82 on Opposite sides of the guide 85. The spring 73 engages both the jaws l! and the jaw 11a to bias the latter toward the former.

This described structure is for use without the magazine and associated parts. With the parts in released position, as shown in Fig. 10, a ring is placed in operating position between the jaws. In this position, the jaw Ila is pivoted away from the shoulder Ma. The handle [5 is moved to the rear. The shoulder 8|a moves out so that it passes the end of the jaw Ha. Further motion of the handle [5 turns the extension 19 and moves the stop 3| forwardly. When the levers 35 come together, the stop 8| will snap to engaging position over the end of the jaw Ila. Upon release of the hook 22, the toggle will move the levers 3S and, therefore, move the jaws Ti and 7101. together. Upon completion of the movement of the toggle past dead center with the strain released, the spring 83 will move the stop 8| free of the jaw Ha. The animal can then unsnap the ring from the jaws.

It is of course understood that the specific description of structure set forth above may be departed from without departing from the spirit of this invention as disclosed in the foregoing specification and as defined by the appended claims.
