HENRY S. WIKEL, OF YORK, PENNSYLVANIA.

SHOE-SEWING-MACHIN E ATTACHMENT.

Application filed February 13, 1915.

To all whom it may concern:

Be it known that I, HENRY S. WIKEL, a citizen of the United States, residing at York, in the county of York and State of ennsylvania, have invented new and useful Improvements in Shoe-Sewing-Machine Attachments, of which the following is a specification.

The invention relates to shoe sewing machine attachments, and more especially to gage attachments for that class or type of shoe sewing machines known as outsole stitchers.

The primary object of the invention. is the provision of a gage attachment wherein the sole is guided in its movement over the stitching table, and the upper oftheshoe protected during the movement of'the said sole, so as to prevent the possibility 'ofthe threads during the stitching operation from penetrating the upper of the shoe, the sole guide and the upper guard for the shoe being operated for the proper adjustment thereof independently of the awl adjuster.

Another object of the invention istheprovision of a gage attachment of this character whereinthe upper guard forthe shoe is so mounted with relation to the stitching table of the shoe sewing, machine that the said guard will be disposed in juxtaposition to the table to protect the shoe upper during the stitching of the sole to the welt while the stitching machine is in operation, the sole guide being mounted so as to be adjusted simultaneously with the upper guard, thereby enabling the successful stitching operation at various distances from the edge of the sole, and at the same time protecting the shoe upper from the awl while the machine is active.

A further object of the invention is the provision of a gage attachment of this character wherein the sole guide and the shoe upper guard are simultaneously adjusted, the adjustmentthereof being eflected in a novel manner and without any inconvenience to the operator of the machine. a

A still further object oftheinvention is the provision of a gage attachment of this character wherein the adjustment of the sole guide and also the shoeupper guard canbe had independently of the adjustment of the awl, the means employed for the adjustment of the guide and guard being manually operated and is located vin convenient reach of Specification of Letters Patent.

the operator of the machine without any interference with the adjustment of the awl.

A still further object of the invention is the provision of a gage attachment wherein the slide for supporting the sole guide and the shoe upper guard can be locked or set in adjusted position. I

A still further object of the invention is the provision of a gage attachment of this character which is extremely simple in construction, reliable, eflicient, and readily and easily operated, and also one which can be manufactured at a minimum cost.

Other objects will be in part obvious and part hereinafter pointed out.

The invention accordingly consists in the feature of construction, combination of elements, and arrangement of parts which will be exemplified in the following construction, and the scope of the application of which will be indicated in the appended claim.

In the drawings: Figure 1 is a fragmentary front elevation of a stitching machine showing the attachment constructed in accordance with the invention applied. Fig. 2 is a fragmentary top plan view of the stitching machine with the gage attachment thereon. Fig. 3 is a fragmentary vertical sectional view through the attachment. Fig. Ais a perspective view of the slide supporting the sole guides and the shoe upper guard, showing the relative position of the latter with the stitching table of the sewing machine. Fig. 5 is a perspective view of the sole guide detached. Fig. 6 is a top plan view of the attachment, showing a modified form of operating sector. Fig. 7 is a perspective view of the adjusting hand lever with the supplemental handle mounted thereon.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates the guide box, which is a part of the framework of the machine, and in which is fitted to move longitudinally the feed slide B, it having at its inner end an upright O which receives a fixed stud D upon which is mounted loosely the usual awl segment E, to whichfis attached the awl F, the said awl segment E being operated in the usual wellknown manner. The feed slide B is adjusted through the medium of the awl adjusting lever G, which has connection therewith as usual. Carried by the framework formed I which clamps the sole of a shoe intermittently to the support or table H at intervals when the awl F is penetrating the shoe sole,

during the stitching operation of the sewing machine, the stitching mechanism being of the ordinary well-known construction and is operated automatically in the usual manner. Detachably mounted on the guide box A beneath the work support or table H is the gage attachment hereinafter fully described.

The gage attachmentcomprises a base or bed plate 10 which is detachably secured to the guide box A so that the outer longer edge of the said plate 10 will be extended a slight distance beyond the forward or front edge of the framework, the said plate 10 being secured to the guide box A in any suitable manner, and on its upper face near the, end thereof beneath the support or table H is formed with a transverse guide rib 11 for the connection of an adjustable slide 12, the same being formed with a groove 13 correspondingly shaped to the rib 11 for receiv ing the same, and this slide is adapted to move transversely of the plate 10, and has threaded therein at its outer side set screws 14 which work against a binding strip 15 arranged within the groove 13 to frictionally engage one side of the rib 11 so as to v secure the slide in adjusted position. The

slide 12 is formed with a post upon which is mounted the shoe upper and sole guide hereinafter fully described.

Mounted on the post 16 at the front thereof is a shoe upper guard comprising a resilient plate 18 which is bent at one edge to form a flange 19 while the free upper edge of the said plate 18 is bent and outwardly flared, as at 21, to conform identically with the contour of the work support or table H, while the flange extends partially around the narrow end thereof, the resiliency of the plate 18 sustaining the portion 21 at all times in contact with the support or table so that when the sole traverses the same the upper of the shoe will be shielded by the plate 18 from the awl, as well as the needle of the stitching mechanism of the machine so that it will be impossible for the upper to ride onto or beneath the support or table during the stitching operation. The flange .19 for a portion of its length abuts the post 16 when the plate 18 is detachably secured thereto so as to prevent any displacement of the plate 18 when the machine is in use, it being understood of course that the plate may be detachably fastened to the post in any suitable manner.

The sole guide comprises a shank or stem 22 formed with a curved guide finger 23 which overlies the support or table H and occasion require.

against which abuts the edge of the sole of the shoe when moving over the support or table, the said finger 23 being extended from one end of the shank and is formed with an offset 24 so that the guide end of the finger will properly overlie the support or table, while the opposite end of the shank or stem 22 is formed with a lip 25 which extends within a channel or groove 26 formed in the seat 17 inthe post 16 to prevent outward dis placement. of the sole guide whenfastened to the post. The shank or stem 22 has integral therewith a right, angular wing27 provided with bayonet or substantially L- shaped slots 28 for receivingset screws 29 mounted in the post 16, it being obvious that by the employment of the said slots 28 the sole guide can be lifted for the quick detachment thereof from the post .16 on loosening the set screws 29, thus obviating the necessity of removing the set screws from the post. Ifurthermore, the slots 28, when cooperating with the set screws 29 permit vertical' adjustment of the soleguide should the Formed on the post 16 or secured thereto isa toothed rack 30 with which meshes a pinion or gear 31 rotatably mounted on a stud 32 rising from the plate 10, and meshing with this pinion or gear 31 is the segmental toothed rack end 33 of a hand operable adjusting lever 34, which is swingingly connected to the plate 10 throughthe medium of the pivot 35 fixed therein. The pinion or gear 31 interposed between the rack 30 and the lever 34 can be dispensed with if desired, and in this instance the rack end 33 ofthe said lever 34 will mesh with the rack 30. With or without the use of the gear or pinion 31, on manipulating the lever 34 the slide 12 can be shifted for the adjustment of the sole guide and the shoe upper guard simultaneously with each other relative to the work support or table H, thereby effectually positioning the sole upon the said support or table for the stitching thereof to the welt duringthe working of the machine. When the sole guide is adjusted a variance can be had in the location of the stitches relative to the edge of the sole and the upper of the shoe so as to gage the extent of the welt. It is of course understood that when the slide 12 is adjusted the set screws l4are loosened to permit free movement thereof should there exist undue binding of the slide on the rib) 11, the set screws being de signed for adjustment so as to operate on the strip 15 to take up any lost motion of the late the lever 3a in the usual manner, the handle 36 when fitted in the lever 34: depends therefrom in convenient reach of the operator of the machine.

In Fig. 6 there is shown a modification of the invention, wherein in lieu of the lever 34: is substituted a short lever 37 formed with a segmental shaped toothed rack end 38 adapted to mesh with the pinion or gear 31, while the opposite end 39 thereof is tapered to serve as a pointer which moves over an indicator face 40 on the plate 10, and in this face at intervals are holes 41 for receiving adjusting pins 42 to lock the lever 37 in adjusted position, the said lever being supported for swinging movement on a pivot 43 mounted in the plate 10, and rising from the said lever 37 is a T-shaped handle 44 which permits the convenient swinging of the lever on removing the pins 42 from the holes 41 in the indicator face 40 for the adjustment of the slide 12 for a purpose hereinbefore set forth. i

From the foregoing description, taken in connection with the accompanying drawe ings, the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is A gage attachment for sole stitching machines comprising a slide adapted for adjustment beneath the work support of the machine, a post rising from the slide and having a seat,a sole guide mounted in the seat in the post and having a guide finger extended above the work support, a wing formed on the sole guide and having L- shaped slots, set screws mounted in the post and received by the slots in the wing for the detachable mounting of the sole guide on said post, and a resilient shoe upper guard detachably secured to the post and having its portion next to the work support correspondingly shaped thereto.

In testimony whereof I afiix my signature in presence of two witnesses.

HENRY S. WIKEL.
