WELT-GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of. Letters Iatent No. 510,655, dated December 12, 1 893.

Application filed April '7 1893. fierial No. 469,481. (No model.)

To all whom it mag concern.-

Be itknown that I, LEWIS D. STINOHFIELD,

of Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements inWelt-Guid es for Shoe-Sewing Machines, of which the fol lowing is a Specification.

My invention relates to weltguides for shoe sewing machines, and the object of my lnvention is to provide a shoe sewing machine with a guide capable of properly presenting to the action of the awl and needle an imitation cork-sole welt as well as the usual Welt, and supporting these welts firmly against any lateral motion or creeping out of their proper path of movement.

To this end my invention consists in the construction and combination of parts as hereinafter described and claimed.

In the drawings,which accompany and form part of this specification: Figure l is a perspective view of the guide. Fig. 2 is a front elevation of the guide. Fig. 3 is a side elevation, showing the two welts in section. Fig. 4 is a section on line 4-4 of Fig. 2. Fig. 5 is a perspective view of the guide from the rear side. Fig. 6 is a perspective view of the guide from the rear side, showing the two welts passing through the guide, and the needle in broken lines. Figs. 7, 8 and 9 are details of difierent parts of the guide.

The'same letters and numerals of reference indicate the same parts in all the figures.

A indicates the main casting, by means of which the guide is attached to the head of a shoe sewing machine, and parts of which cooperate 'with other parts attached thereto and hereinafter described, in forming the guide- Way for the ordinary welt, and another guideway for the imitation cork-sole welt. This casting has a toe-piece a, extending laterally therefrom, or in a direction at a right angle to the path of the curved needle, said toe-piece having a transverse recess a in its base, for the passage of the needle; and a groove 60?, extending from said recess along the upwardly-inclined base of the toe-piece. The casting has also arearward extension a to the base of which is secured one end of acurved plate b, the other end of which extends under the groove d and is secured to the front side of the'toe-piece. The said plate also comprises a concave-convex portion 1), extending between the portions a and a of the casting, and having a'n'otch b forming, with'the notch or, an opening for the needle to pass through, as best illustrated in Fig. 6. The space thus formed between the base of the casting,the eoncavo-convex portionb of theplate b, the under portion of said plate b and the groove a guides the welt Z, one edge of which enters said groove and. is held pressed against the bottom of said groove by a spring tongue or presser b This presser, as shown more clearly in Figs. 4 and 5, is flattened, and has a shank b, which is clamped between the base of the extension a and a'block or clip 19 screwed thereto. By loosening the screwfastening of the block, the shank of the presser may be adjusted and secured again in different positions, in order to accommodate different Widths of welts'between said presser and the groove a The extreme end of the toe-piece is provided with a shoulder a to support the edge of the well: laterally outhe side of the recess a opposite the end of the groove a To the under side of the plate 6, under the extension a is secured the shank of a gage c,'said shank having elongated holes 0' for the attaching-screws 0 whereby said gage may be adj ustably secured in position. Said gage has an elongated shoulder 0 coming against the front'si-de of the plate b, and a lug c under the bottom of said plate and serving to sustain the same. The gage extend s beyond the shoulder 0 as at 0 and'at one end is provided with a triangular-shaped frame 0 whose base is the shoulder 0 The imitation cork-sole Welt 2, which I hereinafter term, for the sake of brevity, the supplemental welt, is shown in the drawings. as

consisting of a strip of leather, bent around a triangular filling; it therefore becomes triangular in cross-section. In the use of the guide in sewing, this triangular-shaped Welt passes through the triangular frame 0 and thethick edge of the welt rests against the shoulders of the gage. g

To hold the supplemental welt against the front of the plate band the shoulder 0 and also permit the use of welts of different thickness, I secure to one edge of the casting A a tongue or finger (Z, preferably of thin spring steel, the lower end being bent or curved, as at d, to extend over the frontof the toe-piece a, andbeing free to spring. Thelateral portion d of the spring-tongue has a flange (1 to take over the upper edge of the welt. Said tongue may be adjusted as to tension by means of asorew d projecting from the main casting and extending through a slot in the tongue, and a nut (Z on said screw. By this means the tongue may be adjusted to different welts.

It will be seen that, with my improved guide, the two welts will be firmly held in position to be stitched together and to the shoe, and the guide is adjustable to welts of different sizes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A welt-guide for shoe sewing machines, comprising in its construction a body-portion having a lateral and a rearward extension, a curved plate fastened to the rearward extension and extending between the same and the lateral extension and forming with said lateral extension a guide-Way for a welt, a gage fastened beneath said curved plate and hav-v ing a shoulder at the front portion, and a resilient tongue fastened to the front side of the body-portion and constructed to hold a sup plemental welt against the front of the guide and against the shoulder of the gage.

2. A welt-guide for shoe sewing machines, comprising in its construction a body-portion having alateral and a rearward extension, said lateral extension having a groove in the under side; a curved plate fastened to the rearward extension and extending between the same and the lateral extension and forming a guide-way for a Welt; an adjustable spring-gage in said guide-Way; a gage fastened beneath said curved plate and having a shoulder bearing against the front portion of the latter, and a triangular frame; and a resilient tongue fastened to the body-portion, and constructed to hold a supplemental welt against the front of the guide and against the shoulder of the last-named gage.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, this th day of March, A. D. 1893.
