Bernard E Mil/ner' 55 INVENTOR.

BY 2mm 44 26 4 WWa flM Patented Apr. 4, 1950 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to new and useful improvements and structural refinements in devices for applying rings to the noses of hogs or similar animals, and the principal object of the invention is to provide a ringer whereby this operation may be performed conveniently and with expedience.

In particular, the instant invention is an improvement on the device which constitutes the subject matter of United States Patent No. 1,879,270, granted on September 27, 1932 to William A. Ingalsbe.

To a substantial extent, the instant invention resembles the device in the above identified patent, but one of the improvements resides in the provision of novel means for equalizing the movement of the actuating handles of the implement so as to centralize the ring blank magazine with respect to the blank closing and applying jaws.

Another feature of the invention resides in structural improvements in the blank magazine itself, whereby the latter is adapted to accommodate blanks of different sizes.

Important advantages of the invention lie in its simplicity of construction, convenience of operation, and in its adaptability to economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure l is a top plan View of the invention, the blank magazine being shown in cross section;

Figure 10 is a perspective View of a lining shell 2 which is usable in association with the follower shown in Figure 9.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of a hog ringer designated generally by the reference character 20, the same being in many respects similar to the ringer disclosed in U. S. Patent No. 1,879,270

and embodying in its construction a pair of members 22, 24 providing at one end thereof a pair of coacting jaws 26, 28, respectively, while the remaining ends of the members constitute a pair of coacting handles 30, 32, respectively, as will be clearly apparent.

The intermediate portions of the members 22, 24 are connected together in a plier fashion by means of a pivot pin 34, the latter being provided at one end thereof with a substantially circular, flat head 36 and with an integral guide block 38, the head 36 being rotatable in a suitable recess 40 with which the member 22 is formed, while the block 38 is provided with a transverse bore 42 extending at right angles to the axis of the pin 34, as will be clearly apparent from Figure 4.

The remaining end portion of the pin 34 is screw threaded and carries a washer 44, a spacer 46 and a nut 48, whereby the pivot pin is retained in position and the members 22, 24 are pivotally held together. A suitable spring 50 has a coiled intermediate portion thereof positioned on the spacer 46, the end portions of this spring being I suitably anchored to the members 22, 24 and matters being so arranged that the spring 50 urges the jaws 26, 28 and the handles 30, 32 to their separated or open positions.

If desired, the member 22 may be provided with a pair of spaced, arcuate extensions 52 which freely straddle the member 24 and are equipped at their outer ends with a suitable set screw 54 for adjustably limiting the opening of the handles and jaws. Similarly, a further set screw 56 may be provided in the member 22 to adjustably limit the closing of the handles and jaws, as will be clearly understood.

The intermediate portions of the members 22, 24 may also be equipped with lateral protuberances '58, 60 respectively, these functioning as finger stops, so to speak, for preventing the fingers of the user from coming too close to the working mechanism of the ringer and sustaining possible injury. 1

A swingable loop 62 may be attached pivotally 3 to the handle 30 and adapted to engage a catch 64 provided on the handle 32, whereby the handles and jaws may be retained in their closed positions when the device is not in use. However, when the device is used, the loop 62 may be simply swung out of the way, so to speak, into a notch 66 formed in the handle 30, as indicated by the phantom lines 68 in Figure 1.

A vertically elongated magazine assembly 10, adapted to receive and dispense the ring blanks I2, is mounted above the jaws 26, 28, this being accomplished in the following manner:

The magazine assembly 10 includes in its construction a vertically elongated holder 14, the lower end of which is rigidly secured to a mounting flange 16 which, in turn, is provided with a central opening I8 to rotatably receive the aforementioned block 38 which projects above the flange 16, as is best shown in Figure 4. The flange 16 is also formed with a plurality of arouate slots 80 which are disposed concentrically with respect to the opening I8 and accommodate a set of screws 82 employed for adjustably securing the flange 16 (and the holder 14) to the head 36 of the pivot pin 34. Inasmuch as the pin 34 is freely rotatable with respect to the members 22, 24, and inasmuch as the magazine holder 14 is secured by the bolts 82 to the head 36 of the pin 34, it will be apparent that the magazine I may be swung from one side to the other as indicated at 84 in Figure 1, notwithstanding the presence or absence of movement of the jaws 26, 28.

A guiding bar or rod 86 is freely slidable in the aforementioned bore 42 of the block 38, one end of this bar being provided with a fork 88 to which are pivotally connected two equalizing links 90, 92 by means of a common pivot screw 94. These links are, in turn, pivoted as at 96, 98 to the respective members 22, 24, and it will be noted that by virtue of this linkage, together with the slidable disposition of the guide 86 in the bore 42, an equalizing effect will be obtained which will assure that the magazine I0 is always centralized with respect to the jaws 26, 28 when the handles 30, 32 are actuated. In this manner, assurance is bad that the blanks I2 discharged by gravity from the magazine are correctly and accurately deposited in the coacting recesses I00, I02

provided for this purpose in the jaws 26, 28 respectively, and if necessary, a proper preadjustment may be made by simply loosenin the aforementioned screws 82 and presetting the position of the holder flange I6 on the pivot pin head 36, as will be clearly apparent.

Inasmuch as the magazine 10 is intended to receive ring blanks which are separably held together in stacks or columns by shellac, adhesive, or the like, means may be provided for separating the lowermost blank in the stack when such a blank drops into position in the recesses I00, I02 of the jaws 26, 28. These means may simply assume a form of two separating blades I04, I06 respectively, attached to the respective jaws 26, 28 by suitable screws I08 (see Figure 1), the blades I04, I06 being provided with beveled separating edges H0, H2 respectively, whereby the lowermost blank (indicated at H4 in Figure 4) is separated from the stack when the jaws 26, 28 are brought together and the blank therein is closed and applied to the nose of the animal.

Referrin now to the construction of the magazine assembly 10, the same includes the aforementioned holder 14 in which is slidably receiv- 4 able a blank receptacle I I6 having an open lower end and a closed upper end H8. The front wall I of the receptacle H6 is provided with a spring clip I 22, while a further spring clip I24 is secured to the top wall H8 of the receptacle, as will be clearly apparent.

These two spring clips I 22, I24 are releasably engageable with outwardly angulated detents I 26, I28 respectively, the detents I26, I28 being provided at the upper edge of the holder I4, whereby the receptacle I I6, after being inserted in the holder, is prevented from being withdrawn upwardly, as will be clearly apparent.

An L-shaped stop I30 may be provided on the front wall I20 of the receptacle I I6, this stop being engageable with the upper edge of the holder 14 and thereby preventing the receptacle from sliding too far down into the holder.

The lower end portions of the holder 14 and of the receptacle I I6 are formed with aligned recesses I32, I34 respectively, which facilitate the application of the entire device to the nose of the animal, indicated at I36 in Figure 4. In other words, the recesses I32, I34 provide sunlcient clearance for the nose of the animal to be placed between the jaws 26, 28 while a ring is being applied.

A blank follower I 38, configurated as is best shown in Figure 9, is slidable vertically in the receptacle II6, this follower having a top wall I40 to which is secured one end of a compression spring I42 by means of suitable clips or clamps I44. The remaining end of the spring I 42 engages the inner surface of the top wall I I8 of the receptacle II6, whereby the follower I38 urges the blanks I2 downwardly toward the jaws 26, 28. A liner shell I46, best illustrated in the accompanyin Figure 10, is removably positionable on the follower I 38, being retained in position thereon by inturned flanges I48 and a bendable tongue I50 with which the respective upper and lower edges of the shell I46 are equipped.

Matters are so arranged that the outside dimensions of the follower I38 are substantially equal to the inside dimensions of the linin shell I 46, while the outside dimensions of the latter are substantially equal to the inside dimensions of the receptacle II6. Moreover, the inside dimensions of the receptacle II6 are substantially equal to the outside dimensions of the blanks 12, so that by employing the follower I38 together with the linin shell I46, the magazine 10 is adapted to accommodate relatively large blanks.

On the other hand, if relatively small blanks are to be used in the magazine, the receptacle H6 is removed from the holder 14 and the follower I38, together with the shell I46, are with drawn from the receptacle, whereupon the shell I46 is removed from the follower and an insert I52, configurated substantially as shown in Figure 8, is placed in the receptacle H6. The follower I38, without the shell I46, may then be slid into the insert I52 in the receptacle H6, and the latter installed in the holder 74. Matters are so arranged that the outside dimensions of the relatively small blanks and of the follower I38 are substantially equal to the inside dimensions of the insert I52, while the outside dimensions of the insert I 52 are substantially equal to the inside dimensions of the receptacle II6. In this manner, the magazine may be quickly and easily converted for use in association with relatively small blanks, this being achieved by selective and independent use of the lining shell I 46 and insert I52, substantially as described.

It is to be noted that the front wall I20 of the receptacle H6 is provided with an opening I55 to receive the spring clip I22 when the receptacle is withdrawn from the holder I14, this being arranged in such manner that the spring clip I22 may retain the spring pressed follower I38 in the upper ortion of the receptacle while the latter is being loaded with blanks. Needless to say, after the loaded receptacle is installed in the holder I4 and the clip I22 engaged with the detent I26, the spring I42 will urge the follower I38 against the column of blanks, as has been already explained.

Finally, an additional spring clip I58 may be provided on the receptacle H6 at the upper edge of the recess or opening I34, the clip I58 extending into the receptacle and preventing excessive downward travel of the spring pressed follower I38 when the supply of blanks in the receptacle is exhausted. Needless to say, the clip I58 may be swung outwardly to facilitate removal of the follower I38 from the receptacle H6, and it should be also understood that the blanks I2 are of a substantially U-shaped configuration, so that the inwardly extending portion of the spring I58, being disposed between the open ends of the blanks, does not interfere with the downward passage of the blanks through the magazine.

It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosures and accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:

1. In a hog ringer, the combination of a pair of members provided at one end with a pair of coacting jaws, a pivot pin connecting said members together, a blank magazine disposed above said jaws and provided with a mounting flange attached to said pin, means for adjusting the attachment of said flange to the pin, and means for equalizing the movement of said members so as to centralize said magazine with respect to said jaws, said means including a pair of links each pivoted to one of said members and operatively connected to said pivot pin.
