Application October 3, 1932. Serial No. 635,962

9 Claims.

This invention relates to a ring clincher which is particularly applicable for ringing hogs, applying clamping wires or rings to fences or other similar purposes wherever it is desired to clinch a wire ring into place.

The principal object of the invention is to provide a portable and manually operated clincher with a magazine for carrying a plurality of unclinched rings from which the rings may be fed into clinching position automatically as used.

Another feature of the invention resides in the adjustability of the magazine to accommodate rings of varying size within certain limits.

Still a further feature of the invention resides 16 in the relative movement between the clinching ends of the clincher and the magazine whereby the magazine will be retracted relative thereto as the ring is clinched so as to be positioned out of the way during the clinching action.

20 The full nature of the invention will be more clearly understood by the accompanying drawing and the following description and claims:

Fig. 1 is a plan view of the clincher showing the ,magazine containing a plurality of unclinched rings. Fig. 2 is a plan view of the reverse side showing the clincher. Fig. 3 is the same as Fig. 1 showing the device in clinching position. Fig. 4 is a section taken on the line 4-4 of Fig. 1.

In the drawing there is shown a portable hand 0 operated clincher of the usual type which is somewhat in the form of a pair of pliers having oppositely disposed jaws 10 and 10a provided with outwardly extending corresponding handles 11 and ,lla, said jaws and handles cries-crossing and having a pivotal connection through the medium of a bolt 12 provided with a head 13.

Slidably supported upon the clincher, there is a magazine 14 having side walls 15 with inwardly extending forward portions 16 to conform with the general shape of the unclinched rings 17. Said walls are of a height to accommodate a number of unclinched rings as illustrated in Fig. 4.

A rear wall 18 is provided with upwardly extending fingers 19 extending to substantially the height of the side walls 16, said rear wall having rearwardly extending supports 20 provided with longitudinal slots 21 through which the adjusting screws 22 extend. Through the medium or 0 the slots and adjusting screws, the rear wall is slidable backward and forward to adjust it to varying sizes of rings.

Extending transversely of the magazine between the side walls and so as to bear on top of the rings, there is a follower bar 23 mounted on the free end of the spring arm 24 which is firmly anchored at its opposite end by the screw 25. The follower bar, through the spring tension of the spring arm 24, continuously bears against the top unclinched ring.

The Jaws 10 and 10a are provided with a curved recess 26 for receiving the lowermost unclinched ring when the device is in the position shown in Figs. 1 and 2. When it is moved to unclinching position, as shown in Fig. 3, the side walls of the recesses 26 in which the unclinched ring is seated force the free ends of the ring together to clinch them.

For obtaining further adjustment of the clinching action, particularly in respect to varying sized rings, the clincher is provided with 1on-- gitudinal slots 27 and 28, through which the pin 5a extends for permitting the opening and closing movement, one of said longitudinal slots having adjustable set screws 29 and 30 extending 15 into the opposite ends thereof for limiting the sliding movement of the pin 25a Within the slots.

In operation, the magazine is filled with a plurality of unclinched rings as illustrated in Fig. 4. When the clincher is open, as shown in 60 Figs. 1 and 2, the spring tension exerted on the upper ring by the follower bar 23 forces the lowermost ring into the position between the walls of the recesses 26. When the clincher is moved to the position shown in Fig. 3, the walls 86 compress the ring, bringing the free ends together in clinched position. Upon opening the clincher, the clinched ring is released and the follower bar forces the next lowermost unclinched ring into position.

Thus, the rings are fed automatically from the magazine into clinching position as the clincher is opened. By means or" the set screws 22, the rear wall 18 of the magazine may be adjusted back and forth to accommodate various sized rings within limits, and the set screws 29 and 30 may be adjusted to vary the throw or the opening and closing movement of the clincher to accommodate the clinching action to the various sized rings.

As illustrated in Figs. 1 and 3, it will be noted that the position of the magazine in respect to the clinching ends of the clincher is retracted so that the magazine will be out of the Way of 105 the clinching action when the ring is being applied. This is permitted by the sliding action of the bolt 12 in the elongated slot of the magazine 14. It is very important that this relative movement take place, otherwise the magazine would to said bar and the other end to said magazine prising a pair of clinching jaws, a magazine bar and the other end to said magazine for exinterfere with the object to which the ring is applied during the clinching action.

The invention claimed is:

1. A portable hand operated ring clincher comprising a pair of clinching jaws, a magazine in fixed relative position mounted thereon for receiving a plurality of unclinched rings and supporting them in position to be fed into said clinching jaws, rigid side walls formed on said magazine, a slidably adjustable rear wall mounted thereon for accommodating said magazine to rings of varying sizes, and means for automatically feeding said rings into clinching position.

2. A portable hand operated ring clincher comprising a pair of clinching jaws, a magazine mounted thereon for receiving a plurality of unclinched rings and supporting them in position to be fed into said clinching jaws, rigid sidewalls formed on said magazine in fixed relative position, a slidably adjustable rear wall mounted thereon for accommodating said magazine to rings of varying sizes, and a spring pressed follower bar adapted to engage said rings for automatically feeding them into clinching position.

3. A portable hand operated ring clincher coinprising a pair of clinching jaws, a magazine mounted thereon for receiving a plurality of unclinched rings and supporting them in position to be fed into said clinching jaws, rigid side walls formed on said magazine, a slidably adjustable rear wall mounted thereon for accommodating said magazine to rings of varying sizes, a cross bar extending between the rigid side walls to bear upon the uppermost ring contained in said magazine, and a spring arm having one end secured for exerting pressure upon said rings for forcing the lowermost ring into said jaws to be clinched thereby.

4.
