Specification of Letters Patent. Patented June 27, 1922,

Application fi1ed'J une '27, 1921. Serial 1\To.480,64 1.

T 0 all whomit may concern.

Be it known that I, JOSEPH M. LnviNsoN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Stapling Devices for Shoes, Etc, of which the'following is a specification.

My invention relates to a staple settlng tool, and has for its object the provision of a relatively simple and easily operated device that may be effectively used for forcing staples through relatively thin sheets of material, such as leather, paper, wood veneer, or the like. and clinching the ends of said staples beneath the body or layers of material.

lVith the foregoing and other objects 1n view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevational view of a staple setting tool of my improved construction.

Fig. 2 is a top plan view of the tool.

Fig. 3 is an elevational view looking against the reverse side of the tool.

Fig. 4 is an enlarged vertical section taken approximately on the line 414 of Fig. 1.

Fig- 5 is an enlarged detail section taken approximately on the line 5-5 of Fig. 2.

Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention, 1010 designate the handles of the device, the forward portions thereof being crossed and pivotally connected by a pin or screw 11. From the point where said handles are pivotally connected they are extended forward to form elongated curved jaws 12 and 13. and the forward end portions of said jaws are extended inwardlv toward each other. The end portion of the lower jaw 12 is provided with a flat face 14 that performs the functions of an anvil against which the pointed ends of he staple engage when said ends are clinched on the under side of the material through which the staple is driven.

Pivotally mounted on pin or rivet 11 is the inner end of a curved arm 15 that lies immediately against the rear side of curved jaw 15. and the forward end of said curved arm terminates in a horizontally disposed block 16 that is positioned directly above the anvil face 140i jaw 12. Formedthrough block 16 is a vertically disposed aperture 17 that is adapted to receive the staple to be driven, and the forward end of upper jaw 13 terminates in a depending head or finger 18 that serves as a hammer, in as much as it bears directly on top of the staple when the same is driven downwardly through the material interposed between anvil surface 14 and the under side of block 16.

Formed through the central portion of curved arm 15 is a short slot 19, and passing therethrough is a pin or screw 20 that is seated in the central portion of jaw 13. Extending laterally from the forward portion of curved arm 15 is a U-shaped bracket 21 upon which rests the lower end of an expansive coil spring 21, the upper end thereof bearing against the under side of the forward portion of jaw 13.

In the operation of my improved staple setting tool, the handles 10 are manipulated so as to swing jaws 12 and 13 apart, and the staple that is to be driven is now inserted into aperture or recess 17 until the upper end of said staple bears against the under side of hammer 18. The ends of the jaws 12 and 13 are now brought together to clamp the interposed work or pieces of material in which the staple is to be driven, and by pressure of the handles 10 toward each other, the hammer 18 on the forward end of jaw 13 will force the staple downwardly through opening or recess 17 through the interposed material, and as the pointed ends of the legs of the staple bear against the anvil face 14 on the end of jaw 12, said pointed ends will be turnedand clinched against the under side of the interposed material The expansive action of spring 21 tends to move the hammer head 18 upwardly out of the aperture or recess 17 and the movement of the arms 13 and 15 away from each other is limited by the pin 20 that occupies slot 19.

It will be noted'that the jaws 12 and 13 have considerable length and that the intermediate portions are spaced 2. substantial distance apart. This construction enables a relatively large piece of work to be accommodated between the jaws, and also permits staples to be set in material a substantial distance away from its edge.

A staple setting tool of my improved tool is comparatively simple, may be easily and cheaply produced, and is very effective in performing its intended functions.

It will he understood that minor changes in size, form and construction of the-various parts of my improved stapling device may bemade and substituted forthose herein shown anddeselibed without departing from the spirit of myinvention,the scope of the other jaw and having an offset free end provided with an aperture, a bracket formed on the arm, an expansible spring arranged between the bracket and second mentioned aw, and a finger of a w dth re- "duced witlrrespect to "the width of the second mentioned jaw, said finger being iformed on the free end of the latter and slidable in the aperture, said aperture being of such" a Width as to slidablyreceive' and sustain a staple in. proper abutting relation with respect to the finger during the entire movement of the staple andfinger toward the anvil. i .v

Inte'stimony whereof I have signed my name to this specification.

i JOSEPH M. LEVINSON.
