BENJAMIN Gr. RAND, OF NORTH. TONAWANDA, NEW YORK, ASSIGNOR TO THE BAND COMPANY, OF NORTH TONAWANDA, NEW YORK, A CORPORATION OF NEW YORK.

WIRE-STITCHING MACHINE.

Patented June 10, 1919.

Application filed August 28, 1916. Serial No. 117,212.

To all whom it may concern:

Be it known that I, BENJAMIN G. RAND, a citizen of the United States, residing at North Tonawanda, in the county of Niagara and State of New York, have invented new and useful Improvements in Wire-Stitching Machines, of which the following is a specification.

This invention relates to improvements in stapling or stitching machines, and particularly to means for guiding or gaging the articles to be stitched.

It is the object of this invention to provide means on the work-supporting table which will cause the stitching mechanism of the machine to produce stitches obliquely to the edge of the article, as such stitches can be inserted with greater facility and neatness than stitches parallel with the edge of an article. Parallel stitches require the use of closely-arranged parallel guides over which the articles to be stitched must lap, preventing them from lying flat on the table and producing inferior work.

A further object is to produce a simple and eflicient device of this character which can be readily applied to and removed from the stitching machines now on the market.

In the accompanying drawings:

Figure 1 is a fragmentary vertical section of a stitching machine, embodying my improvements. Fig. 2 is an enlarged fragmentary top plan view of the table of the machine to which my device is applied.

Similar characters of reference indicate corresponding parts throughout the several views.

The stitching or fastening mechanism forms no part of my present invention and may be of any suitable or well known con struction, such for instance as shown and described in Letters Patent of the United States No. 662,184, issued November 20, 1900 to T. A. Briggs and T. Barrett. In the drawings, only such parts are shown as are related to the improved guide.

1 indicates the fixed horizontal arm or gooseneck of the stitcher having suitable bearings in which the driving shaft 2 is journaled. Arranged at the front end of this arm is the wire supply spool 3 which is loosely mounted on a spindle 4 secured to said arm. From thisspool the wire passes to a suitable cutter mechanism, not shown, which severs the wire to the desired length to form the stitches or staple-blanks. Each staple blank is guided onto ananvil bar 5 which SllClGS'lll a curved grooved 6 arranged in a vertically-movable presser 7. A vertically movable bending bar 8 is arranged in front of the presser 7 and moves in a vertical guide bar 9. Upon the downward movement of this bending bar the legs of thestaples or stitches are formed after which they are clenched by the customary clenching jaws, not shown. The legs of the staple enter the usual slots o-r throats 10 located below the staple forming and driving devices.

Arranged adjacent to the mechanism previously described, is a horizontal table 11 which supports the articles to be stitched. A guide or gage plate 12, preferably in the form of an isosceles triangle, is secured to the top of this table by screws 13 or other appropriate means, so that the opposite sides thereof converge toward the stitching mechanism. This gage plate is located centrally on the table 11 with its apex in line with the center line of the stitching mechanism, so that its side edges are symmetrically disposed with reference to the latter. 'As shown in the drawings, the wide end of the plate overhangs the table a suitable distance to present an extensive bearing surface at its opposite edges to the articles to be stitched, while the apex of the plate is definitely positioned in front of the stitching parts of the machine, so as not to interfere therewith and to permit the article being stitched to be properly located relatively to said parts.

To limit the forward movement of the article to be stitched and properly position it preparatory to that operation, a front gage or stop 14, preferably in the form of a flat spring, is fastened to the rear portion of the table 11 with its upper edge projecting normally above the surface of the table, as shown in Fig. 1. This gage is arranged in the opening 15 in the table which is necessary for the vertical movement of the presser bar 7 and associated parts of the stitcher. The gage, being made of a flat strip of metal, is resilient enough to yield to the descending presser bar during the stitching operation and to return to its norin al position after that operation. The gage is preferably so located that the stitches in the articles will be close to their edges, al-

though the gage may be made adjustable, if desired to place thestitches at a greater or less distance from the edges.

The article illustrated in the drawings, by

havin way of example, is an index card 18 at its lower edge a pocket or holder adapted to receive an index or memorandum slip, not shown, and formed by a folded strip 19 of celluloid stitched to the card.

In the use of a machine equipped with the improvement, the indexcard is placed fiat on the table with its folded edge against &one 1 of the side gages formed by thesideedges of the guide 12 the stop 14, as shown by full lines in Fig. 2. While the card is in this position, the machine is operated to form one or -more stitches 20 therein. iThe other end of the card is then likewise stitched by reversing it end for end and placing it against the opposite edge of the guide, as shown by dotted lines in Fig. 2.

of the index card or other article, which converge toward its upper end;

By the use of this improved guide the presenting the articles to the stitching mechanism. Moreover, the-guide is small and Copies of thispatent may be obtained for five cents each,-

I claim as my invention: V 1'. Ina-stitching machine, the combination with fastening mechanism and a table for supporting the articles to be fastened of a triangular guide mounted on said table with its apex ,facinglthexfa-stening mechanism, the lateral forwardly-converging edges of said guide forming side'gagessymmetrically dis posed-with referenceto the fastening mechanis1n,-and the portions of said *table on opposite sidesfof said guide being unobstructed to allow the article to lie flat thereon and againstthe side ed-gesof the guide.

2. In a stitching 'machine, the combination with fastening mechanism and a table-for supportingthe articles to be fastened, of a front gage-arranged adjacent to the surface of said table and located'on the front side of the fastening mechanisimand a triangular guide -mountedon said table with its apex facing said-fastening mechanism and separated therefrom, leaving between 'the guide and the fastening mechanism an unobstructed space for the corner of the article to be fastened, the forwardly-converging edgesof the guide b'eingsyinmetri'cally disposed with relation to the "fastening'mechamsm'.
