SEWING-MACHINE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 524,739, dated August 21, 1894.

Application filed March 3,1894. Serial No. 502.266. (No model.)

To @ZZ whom it mayconcerm Be it known that I, WINEIELD S. SOULE, a citizen of the UnitedStates, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Sewing-Machine Attachments, of which the following is a specification.

This is a device for enabling a sewing ma` chine to stitch top facings on boots and shoes.

The nature of the invention is fully described below, and illustrated in the accompanying drawings, in which- Figure 1 is an end elevation of a portion of a sewing machine provided with my improved attachment. Fig. 2 is a front elevation of the same, a portion of the band or top facing being represented as broken out. Fig. 3 is an enlarged perspective view showing the guide piece in position, and in operation upon a top facing or band on the inside of a gaiter boot. Fig. 4 is a detail in vertical section, a portion of the strip or bar N being represented as broken out. Fig. 5 is a plan of the work plate. Fig. 6 is a detail in plan of the adjustable loopeye between the reel and the guide piece. Fig. 7 is a detached view of the sliding guide plate between the two leaves of the guide piece.

Similar letters of reference indicate corresponding parts.

a represents the work-plate, b the head of the machine, b the arm, c the presser bar, d the presser foot, and e the needle.

A represents a band or top facing which is to be stitched as at A to the portion A of the boot by the aid of my attachment. This band or top facing A is wound upon a reel which consists of the circular shell B provided with the sides or rim B and supported by the head b, and the circular spider or disk C of size to fit into said shell, as shown in Figs. l and 2. This shell and spider or disk are hung upon a spindle D threaded on its outer end at D (Fig. 2) which end projects sufficiently beyond the spider C to allow a spiral spring f to be held against the hub G of the spider by means of the nut g, thus causing the spider to be pressed against the edges of lthe coil produced by the band A inside the reel. A set-screw g can be provided to enter the hub of the spider and set against the shaft D.

As the band A leaves the reel, it passes between the rolls E supported in the frame E which is sustained by the reel, and a suitable register h records the number of yards passing from the reel. After the band A has passed between the rolls, it passes down through a guide or loop-eye, which consists of a bracket F extending from the head b or foot of the reel and provided at its end with a grooved way F. See Figs. 2 and 6. Extending from this grooved way is a bent guidewire F", and a bent wire H of substantially the shape shown has its outer end adapted to overlap the outer end of the wire F, while its inner end I-I is broadened and provided with a slot H, such broadened portion lying in and being adapted to slide in the groove in the part F. By means of a set-screw Z, the wire H is moved back and forth so as to produce, in connection with the wire F,aloopeye adjustable t0 different widths of bands A.

From the loop-eye, the band A extends down into the guide-piece, shown in Figs. l, 2, 3, and 4. This is formed on a curve, as shown, and consists of two parallel or concentric walls, K J, joined at their inner ends by a connecting wall. In other words, the guidepiece is a plate bent back upon itself horizontally, but leaving a space between its two portions, and then bent on a curve vertically. The lower portion of the part K of this guidepiece is adj ustably secured by a screw m to a plate L, which is provided with a slot L. This plate extends horizontally from the foot d across the path of the band A. This band or facing A extends through the guide-piece onto the work-plate a beneath the plate L, and is held against the inner edge of the guidepiece,z`. e., against the curved wall which connects the parts J K--by a curved guidestrip or bar N within the guide-piece J K, said guiding-strip N being adjustable horizontally, so as to be moved against the edge of the band, by means of the screw I) which screws into the strip N and has its shoulder P bearing against the edges of the part J next a horizontal slot J therein. (Figs. 2 and 4.) In order to lengthen the adj ustability of the strip N, the part J (and the slot J is extended at J', as shown in Figs. 2 and 3. An index R (Figs. 2 and 7) extends from the strip or bar N through the slot J to a scale R on the outer surface of the part J of the guide- IOO ' A with relation to the Work-plate and guideplate.

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

l. In combination, the vertically curved guide-piece consisting of the two parallel or concentric Walls K J joined at their inner ends by a connecting Wall, the correspondingly curved guide-strip N adjustable horizontally within said guide-piece, said guide-strip being provided with the screw P and said guidepiece being provided with the slot J, the horizontal extensions J made integral with the guide-piece, and the gage-plate S provided Withl the upturned lip S adjustably secured to the work-plate, said strip N being provided With an index R and said curved guide-piece being provided with a scale, substantially as set forth.

2. The guide, consisting essentially of the bracket F provided With the grooved Way F', the bent Wire F, bent overlapping Wire H provided With the slotted thickened end H for moving in the grooved Way, and the screw Z, substantially as set forth.

WINFIELD S. SOULE.
