United States Patent HOG RINGER William Ray Van Zante, 'Otley, Iowa Application May 4, 1954, Serial No. 427,424

Claims. (Cl. 1-187) This invention relates to a hog ringer, and more specifically is concerned with a hand tool for automatically applying conventional clips of the type formed from bendable metallic wire and initially having a substantially U-shape and being bendable to a closed looped condition when applied.

An object of this invention is to provide a hog ringer having a pair of movable and pivotal jaws for engaging successive single wire clips for deforming the U-shaped clips into a substantially looped clip thereby clinching the clip as desired.

Yet another object of this invention is to provide a hog ringer having a manually movable handle for providing the force necessary to clinch the hog ring and also provided with means for automatically feeding a single clip into the hog ringer and automatically returning the hog ringer to an initial position for repeat performance of the clinching operation.

A still further object of this invention is to provide a hog ringer which is simple in construction, easy to use, efficient in operation, Well adapted for its intended purposes and relatively inexpensive to manufacture.

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 side elevational view of the hog ringer of the present invention;

Figure 2 is a top plan view of the construction of Figure 1;

Figure 3 is a vertical section taken substantially along a plane through the longitudinal center line of the construction for showing the internal arrangement of the pair of operating jaws and the actuation means therefor;

Figure 4 is a detailed perspective showing the jaw synchronizing means and the means for separating adjacent clips;

Figure 5 is a sectional view similar to Figure 3 showing the details of construction with the handle moved to the clinching position and the relative position of the jaws and hog ring clips; and

Figure 6 is a top plan view of a plurality of the hog rings which may be secured together for insertion in the hog ring supply magazine thereby eliminating the tedious process of loading the magazine.

Referring now specifically to the drawings, it will be seen that the numeral 10 generally designates the hog ringer of the present invention and includes a generally elongated flattened tubular hollow casing 12 having a depending stationary handle 14 at one end thereof and having a U-shaped Opening 16 at the other end thereof for permitting discharge of the clinched hog rings or wire clips.

Referring now specifically to Figures 3 and 5, it will be seen that a movable handle 18 is pivotally mounted 2 ,756,427 Patented July 31, 1955 ice on a suitable pivot pin 20 and the handle 18 projects through an opening 22 in the underside of the casing 12 and the inner end of the handle 18 is provided with a curved portion generally indicated by the numeral 24. The lower end of the handle 18 terminates substantially even with the handle member 14 and is shaped substantially in the nature of a hand grip 26. A screw threaded stop member 28 is threadedly engaged with a nut 30 secured to the forward edge of the tubular handle 14 for engaging the rear of the pivotal handle 18 when the handle 18 is moved toward the stationary handle 14 for operation of the hog ringer 10, as described hereinafter.

It will be seen that the outer or forward end of the casing 12 adjacent the opening 16 is provided with a pair of inwardly converging upper and lower walls 32 and a pair of jaw members 34 engage the wall 32 for sliding movement thereon and the jaw members 34 are pivotally secured to a generally A-shaped connecting link 36. The jaws 34 are connected to a circular member 38 on each corner of the A-shaped link 36 by a substantially curved portion 40 at the rear end of each of the jaws 34. The other end of the A-shaped link 36 is connected to the curved portion 24 of the handle 18 by the use of a suitable circular member 42. It will be seen that the movement of the handle 18 is transferred to the A-shaped link 36 and then to the jaw 34 wherein the jaws 34 move forwardly and toward each other due to the convergence of the walls 32 which slidably engage the jaws 34. The inner surface of each of the jaws 34 is provided with a U-shaped recessed area 44 for receiving a T-shaped portion 46 of a synchronizing link 48 which has a rear end 50 engageable with the A-shaped link 36. The synchronizing member 48 is provided with a right angularly extending lug 52 on one side thereof for projecting through an elongated slot 54 in one side of the casing 12 and a tension coil spring 56 is secured to the lug 52 at one end and to an upstanding lug 58 on the casing 12 at its other end for urging the jaws 34 and the A-shaped link 36 to a retracted position. An offset wedge member 60 is provided on the synchronizing member 48 in opposing relation to the lug 52 for separating a single U- shaped wire clip 62 from the next adjacent wire clip which it is secured to by suitable adhesive or other means for a purpose described hereinafter.

Referring now specifically to Figures 1 and 2, it will be seen that a supply magazine 64 is provided to one side of the casing 12 adjacent the forward end thereof and is in communication with the interior of the casing 12 substantially just in front of the jaw members 34. The magazine 64 is generally oval shaped and includes a pair of inner members 66 which form a tubular member substantially the shape of the inner area of the U-shaped clip 62. An elongated longitudinal slot 68 is provided in the upper and lower longitudinal edges of the magazine 64 and right angularly extending slots 70 are in communication with the elongated slots 68 at their outer ends for a purpose described hereinafter. An arm 72 of generally U-shaped construction is pivotally secured to lugs 74 at the upper edge and lower edge of the casing 12 and a single arm 76 is pivotally secured to the bight portion of the U-shaped arm 72 by a suitable pivot pin 78. A torsion spring 80 is positioned around the pivot pin 78 and has one end engaging the bight portion of the arm 72 and the other end hooked over the arm 76 substantially as illustrated by the numeral 82. The outer end of the spring biased arm 76 is generally U-shape as indicated by the numeral 84 and includes a handle member 86 for grasping with a finger and'overcotningthe tension of the spring 80 wherein the inturned end portion 88 of the U-shaped arm may be moved in the slot 68 in the magazine 64. It will be seen that the inturned end portions 88 may be moved into the laterally extending slots 7% thereby permitting the insertion of a plurality of U-shaped wire clips as illustrated by the numeral 90 that are formed in assembled relation and secured together by suitable adhesive or other means thereby permitting the insertion of a group of wire clips 90 with a single outward movement of the inturned end portions 88, and the arm 76. Itwill 'be seen that the spring 80 continuously urges the wire clip 90 toward the casing 12 for engagement by the jaws 34 and clinching as illustrated in Figure 5.

In operation, the handle 86 is pulled outwardly thereby moving the inturned end portions 88 of the arms 84 into the laterally extending slot 70 thereby permitting the magazine 64 to be filled with a plurality of secured together U-shaped wire clips, such as hog rings, and theinturned end portions 88 are then moved back into the longitudinal slots 68 thereby urging thewire clips 90 toward the interior of the casing 12. The innermost of the wire. clips fill as indicated by the numeral 62 is positioned between the clip engaging seat 92 on each of the jaws 34 with the open portion of the clip 62 facing the opening 16 in the outer end of the-casing 12. The movable handle 18 is then pivoted about pivot pin 20 thereby urging the A- shaped link 36 forwardly together with the jaw members 34, which slide forwardly along the upper and lower walls 32 of the 'casing 12 wherein the walls 32 force the jaws inwardly into gripping engagement with the U-shaped clip, 62 thereby clinching the clip 62 substantially as illustrated in Figure 5. \The jaws 34 slide along the walls 32 and also pivot about the circular members 38 on the end of the link 36. The transverse member 46 on the synchronizing member 48 guide and limit the pivotal movement of the jaws 34 since the transverse member 46 is loosely positioned in recesses 44 which permits relative movement of the jaws caused by arcuate movement of point 42 thereby synchronizing their action and assuring accurate clinching of the clip 62. The action of the tension spring $6 returns the jaws 38 and the A-shaped link 36 as well as the handle 18 to the original retracted position for a repeat operation. The sharpened actuating said jaws, and interconnecting means provided member 69 inserts itself between the innermost clip 62 V and the next adjacent clip thereto thereby separating the inner clip 62 for clinching. Obviously, the device may be constructed of any readily obtainable materials and except for reloading the magazine occasionally, the device is completely automatic and of relatively simple construction.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, 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 shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims. a
