0W6 550111! Paz 'adiso Patented Dec. 2, 1930 UNITED STATES 'PeTE FRANK rAaAnIso, or PHILADELPHIA, rENnsY Lv Anm i snon-s'rrrcnnn' ATTACHMENT Application filed May 29, 1922. Serial no. 281,438.

My invention relates to machines for sewmg soles to the uppers of shoes and more particularly to an attachment for such machines.

In reso-ling shoes, the sole is tacked to the upper, trimmed to shape, provided with a furrow, stitched to the upper with the outer parts of the stitcheslying in the furrow, and the furrow closed so that the stitches are embedded in the leather.

The object of this invention is to provide an attachment for shoe stitchers which will open a furrow ahead of the needle and close it afterthe stitches are made, thus combining three operations into one.

The attachment comprising the invention consists of a guide member, a knife and a furrow closing member so positioned on a support that, when the same is attached to a shoe sewing machine, the knife will be positioned ahead of and the furrow closing member in the rear of the stitching mechanism. The furrow closing means may be in the nature of a roller. The guide member may be detachably connected with the supporting member and may be yieldably adjustable relative thereto. The knife may also be mounted for adjustment vertically and angularly to the support.

In the drawings:

Figure 1 is a front view of a fragment of a conventional shoe stitcher upon which my invention has been installed, and V Figure 2 a fragmentary cross-section, taken on line 22 of Figure 1, showing the relation of the furrow opening knife and the needle of the stitcher.

Figure 3 is an enlarged top plan view of the attachment.

Figure 4 a front View thereof, and

Figure 5 a side View, looking from the left of Figure 4.

In Figure 1, I have shown one of my improved attachments installed upon a shoe stitcher, such as are manufactured by the Landis Machine Company,of St. Louis, Mo., only a fragment of which has been shown as these machines are well known. In Figures 3, 4, an d5, I have shown in detail an attachment for this type of stitcher but theiinven tion may be readily adapted to other types. I

Referring first to Figures 3, 4, and 5, the attaching member 10 has a body part 11 which conforms in shape and size to a presserfoot or guide which forms apart of the stitcher. A knife 12, secured to the front end of the attaching member by a screw 13 extending through a slot 14 in the knife, is preferably held against rotation by being disposed between shoulders 15 and 16 formed on the front end of the attaching member;

slot 14 allowing vertical adjustment of the knife. An arm or extension 17 is secured to or formed integral with body part 11 and provided at its outer end with a shaft 18 carrying a presser roll 19 whose function is to close the furrow formed by the lmife.

The attachment is preferably provided with an adjustable shoe guide and this may be accomplished by forming a notch 20 in arm 17 and mounting therein an offset part 21 of a guide 22. The guide may be moved toward the knife by means of a screw 23 and moved in the opposite direction by means of springs 24 disposed in recesses 25 and 26 formed, respectively, in offset part 21 and arm 17.

Attaching member 10 is provided w th holes 27 and 28 matching the holes occupied by the screws which hold the presser-foot on the stitcher so that the presser-foot may be removed and the attachment bolted in its place. In using the attachment, knife 12 is adjusted to make the required depth of furrow, screw 23 turned so that the knife will cut the furrow the correct distance from the edge of the sole of the shoe to be stitched, the stitcher put in operation, and the shoe passed therethrough with the edge of its sole pressed against guide 22. Knife 12 will cut .a furrow in the sole, needle 29 will stitch the sole to the upper with the outer part of the stitches lying in the furrow, and roll 19 will close the furrow over the stitches thus formed.

The attachment as hereinbefore described is to be considered as illustrative of my invention and it is to be understood that various changes, modifications and adaptations thereof may be made within the scope of the iii.

invention as hereinbefore disclosed and hereinafter claimed.

I claim:

In a machine for stitching soles to shoes, means for embedding the stitching in the sole including an attaching member, a knife mounted thereon, a shoe guide mounted on the attaching member and having recesses, springs in the recesses abutting the attaching member, and a screw for moving the guide against the action of the springs.

In testimony whereof I have signed my name to this specification.

FRANK PARADISO.
