UNITED STATES PATENT oEEIoE.
ARTHUR E. COUPAL, OF SOUTH BOSTON, MASSACHUSETTS, ASSIGNOR T0 BUFFALO SHOE 00., OF BUFFALO, NEW YORK, A CORPORATION OF WEST VIRGINIA.
To all whom it may concern:
Be it known that I, Aarnna E. COUPAL, a citizen of the United States, residing at South Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Staples, of which the following is a specification.
This invention relates to improvements in staples and particularly to those adapted for use in the manufacture of boots or shoes to fasten a welt or rand to an insole or an outer sole to an inner sole or to a welt. In work of this character, it is often desirable that the staple should be placed very close to the edge of the sole and yet it should not pro'ect to said edge, otherwise it would inter ere with the trimming thereof. It is also desirable that in clenchin the staple in a soft material, like leather, t at the ends should turn inwardly from the edge of the sole in order to obtain a firmer hold therein and to prevent the breaking out of the leather between said staple and the edge of said sole. and again in making a water )roof shoe it is necessary that the staples be p aced close together in order to prevent water from leaking through the cracks, and to do this the legs of said staples must be so clenched that they will not interfere with the legs of the staples adjacent thereto.
The object of the invention is, therefore, to provide a staple which may be manufactured at a minimum cost in very few operations and being so formed in its manufacture that, when driven against a fiat anvil, the extremities of the legs thereof are bent toward each other and laterally thereof on one side of a plane passing longitudinally through the body 0 said staple, thereby producing a staple which is adapted to meet the above requirements.
The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claim thereof.
Referring to the drawings: Figure 1 is an elevation of a staple embodying my invention. Fig. 2 is an elevation of the same as viewed from the right of Fig. 1. Fig. 3 is a section taken on line 3--3 of Fig. 1. Fig. 4 is an elevation of the staple as it would a pear after the clenching of the same. 1 5 is a plan view of a portion of a shoe 501% having several staples clenched therein. Fig. 6 is a detail section taken on Specification of Letters Patent.
Application filed November 15, 1911.
Patented Sept. 24, 1912.
Serial No. 860,362.
line 6-6 of Fig. Fig, 7 is a perspective view of the sta le embodying my invention.
Like numerals refer to like arts throughout the several views of the rawings.
In the drawings, 8 is a staple having legs 9 and 10 formed thereon and provided with faces 11 and 12 substantially parallel to each other and oblique to a plane passing longitudinally through the body of said staple and containing the median axle line of the wire constituting the legs of said staple, said faces being located upon the Same side of said plane and terminating at one side of said plane. Upon the legs 9 and 10 in addition to the faces 11 and 12 are surfaces 13 and 14 oppositely disposed on the outer edges of said le s adjacent to their extremities and inclined toward each other and toward a longitudinal plane extending laterally of said first mentioned lon itudinal plane.
(i ne of the particular advantages secured by the construction hereinbefore described is that in the manufacture of said staple but few operations are required to form the same, the wire which forms the blanks being preferably severed from a continuous piece of wire by a cutter which in one operation cuts dlagonally across said wire formin the oblique face 11 and the oppositely inclined surfaces 13 and 14. The next operation is to form the other oblique face 12 which is accomplished in a single operation by bending the blank, the final operation being to bend the blank to form the legs 9 and 10 which completes said staples and leaves it in a condition to be driven llltD the work.
As an example of the many uses to which said staple ma be put, I have illustrated in Figs. 5 and 6 t 0 same driven into the toe of a boot. The staple 8 is driven along suit able guides and into the sole 15 and welt. 16 with the oblique faces 11 and 12 toward the edge of said sole, until the faces 11 and 12 cooperating with the surfaces 13 and 14 engage a flat face 17 of an anvil 18, whereupon the extremities of the legs 9 and 10 are forced inwardly away from the edge of said sole and toward each other. The positions of said extremities with relation to each other permit the staples to be laced as close together around the toe of a ot as on the si es thereof without the le of one of said staples interfering with t ose of adjacent sta les and also permitting said staples to be p aced very near to the edge of said sole and still securing a firm hold therein.
It will be noted that with a staple of the character hereinbefore described no recesses are required in the anvil to turn the extrem-- ities in the proper directions as the beveled faces thereon are ada ted to govern this, thus making said sta-p e better adapted for use in boots or shoes, for, where a recess has to be em loyed the surface of the leather bearing tiereagainst is apt to be roughed up or injured owing to the yielding surface thereof being pressed into said recess.
Having thus described myinvention,what I claim and dmire by Letters Patent to secure is:
As an article of manufacture, a staple with two legs having parallel faces adjacent to the extremities of said legs, oblique to a plane passing longitudinally throu h the body of said sta 1e, and containing t 1c median axial line 0 the wire constituting the legs of said staple, said faces terminating at one and the same side of said plane, said legs also having outer oppositely disposed surfaces inclined toward a longitudinal plane extending laterally of said first mentioned longitudinal plane, whereby when said staple is driven against a. flat anvil the extremities of said le 5 are caused to turn toward each other and aterally of and on the same side of said longitudinal plane.
In testimony whereof I have hereunto set my hand in presence of two subscribing witmesses.
