UPSETTING-TOOL FOR EYELETS.

Specification of Letters Patent.

Patented Dec. 29, 1914.

Application filed June 16, 1914. Serial No. 845,357.

To all whom it may concern:

Be it known that I, GEORGE M. WILLIAMS, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented new and useful Improvements in Upsetting-Tools for Eyelets, of which the following is a specification.

This invention relates to a tool the purpose of which is to facilitate the upsetting of eyelets, particularly when such eyelets are used for attaching together metal reinforcing bands, such as used on packing cases or boxes.

A principal object of the invention is to produce a tool for this purpose which can be readily applied between the box and superposed straps which are to be attached together, and which is adapted to upset the eyelet when driven down through co-incident openings in the superposed straps.

A further object of the invention is to provide improved means for disengaging the attached parts or straps from each other after the eyelet has been upset. In the present instance, the device includes an upwardly projecting stud which facilitates the upsetting of the eyelet, and the means for disengaging the device operates to disengage the eye from the stud referred to.

7 Further objects of the invention will appear more clearly hereinafter.

In the drawing, which fully illustrates the preferred embodiment of my invention,

Figure 1 is a plan of the tool showing a portion of a reinforcing strap the .ends of which are to be connected by means of the tool. Fig. 2 is a longitudinal section through the tool, taken on the line 2-2 of Fig. 1, and showing a portion of a corner of the box, and also showing the superposed straps with the eyelet in position to be struck by a hammer to upset the eyelet. This View illustrates a hammer head about to strike the eyelet. Fig. 3 is a view similar to Fig. 2, but showing only a portion of the tool and indicating the disengaging shoe in the act of disengaging attached straps from the eyelet upsetting means. Fig. i is a side elevation with parts in section, showing the manner in which the eyelets connect the superposed ends of the reinforcing straps, and this view also shows the portion of the box to which the strap is attached. Fig. 5 is a perspecti e Showing the end of a box or packing case having the reinforcing metal strap, the ends of which are represented as attached together through the instrumentality of this tool. Fig. 6 is a side eltfliittlOIl showing a modified form of the too Referring more particularly to the parts, in its preferred form the tool comprises a base member or blade 10 which is in the form of an elongated plate, preferably having a forward beveled edge 11. On the side of this blade I provide means adapted to aline with co-incident openings 12 in the superposed strap ends, or straps 13 and 14. This upsetting means is preferably formed of a small anvil 15 which may be of circular form and set in a socket 16 in the upper face of the blade. This anvil is preferably of circular form and preferably presents a stud 17 which projects upwardly from its disk-shaped body, and at the base of this stud the anvil is preferably provided with a circumferential recess or groove 18. By reason of the beveled edge 11, this blade or face member 10 is readily inserted between the wall 19 of the boX 20 and the reinforcing strap, the ends of which are to be attached by an eye 21. In this way, the tool is inserted so that the stud 17 alines with and projects upwardly into the alining opening, the eyelet 21 is then applied, as indicated in Fig. 2, with the lower end of its sleeve 22 resting in the groove 18, and the eyelet is then forced downwardly or driven downwardly by means of a hammer 23, or other means.

If desired, in order to facilitate the upsetting of the lower end of the sleeve of the eyelet, I also provide the sleeve with a plurality of longitudinal cuts or incisions 24:. As the eyelet is forced downwardly, the groove 18 upsets or crimps outwardly the lower end of the sleeve so that it forms the lower end of said sleeve into a flange or clamped head 25, see Fig. 4, said head coming against the under face of the lower strap 1 1. After upsetting the eyelet in this way, the tool may be removed by slightly raising the straps and the eyelet until the stud is disengaged from the eyelet. The tool may then be withdrawn.

Preferably, I provide means which may constitute an attachment for freeing the tool to permit its withdrawal, for this purpose, I prefer to provide a disengaging shoe 26 preferably in the form of a flat plate having pin and slot connections 27 with the blade, said pin and slot connections including the screw 28 lying in the slot 29 and retaining the shoe on the side of the blade. The forward end of this shoe is preferably formed into two forks 30 which preferably have forwardly beveled edges 31 adapted to slide under the attached straps and leave the same so as to disengage the eyelet from the stud. In order to guide the shoe 26 most effectively, I prefer to place the pins 27 out of line with each other.

Any suitable means is provided for fore ing the shoe under the straps. In Fig. 6 I illustrate a simple form of the invention, in which a disengaging shoe 32 is formed with an outwardly extending handle or finger 33 which may be grasped in the hand so as to shove the shoe in or out, or this finger 33 may be struck with a hammer a light blow and then similarly struck a light blow so as to drive it out again.

Again, in the preferred form of the tool, I provide means for enabling the disengaging shoe 26 to be moved in and out by actuating a handle 34 which is preferably pivotally attached at 35 on an extension 36 extending laterally from the blade. This handle 34 may be connected in any suitable manner such as by a link 37 with the rear end of the shoe, and if desired, a spring 38 may be provided at the pivot point 35, which tends to hold the spring in a withdrawn position,

said spring preferably comprising a coil 39 wound around a pivot pin 35 and having an arm 40 pivoted in the extension 36, and a second arm 41 the end of which is thrust against the forward edge 42 of the handle or lever 34.

The blade 10 is preferably formed with an integral. handle 43 opposite the handle 34. Evidently, by pressing the, handle 34 toward the handle 43 the shoe will be forced forwardly on the plate, and when the pressure is released, the spring will return the shoe and handle to their normal position.

After the eyelet 21 has been upset, the strap ends or straps 13 and 14 may be secured to the box by suitable fasteningdevices such as nails 44, which may be driven in, as indicated in Fig. 4.

lVhen the disengaging shoe is forced forwardly, evidently the forks 30 move past the eyelets 21 and on opposite sides of the same so as to operate effectively in disengaging the eye from the stud.

Although I have described the stud 17 as being formed on a separate piece or anvil 15, evidently, if desired, the blade could have its stud formed as an individual part thereof.

It is understood that the embodiment of the invention described above is only one of the many, embodiments or forms the invention may take, and I do not wish to be limited in the practice of my invention, nor in my claims, to the particular embodiment set forth. i
