To all whom it may concern,-

Be it known that I, GEORGE JOHN STE7 VENS, of London, England, but now temporarily residirig in the city, county, and State of New York, have invented a certain new and useful Improvement in Guides for Sewing- Machine Attachments; and I do hereby declare the following to be a full, clear, and exact specification of the same.

The object of my invention is to construct a simple, inexpensive, and efficient guide for sewing-machine attachments, and more particularly that class of such attachments as are adapted to blindstitch or fell, serge or overcast, and overseam; to make such a guide readily adjustable, so that cloths of varying thicknesses may be readily stitched, and to guide both the fold of the cloth and the lower single layer of cloth when blindstitching or felling. I accomplish this object by the construction, arrangement, and operation of parts hereinafter described, the particular features of novelty which constitute my invention being pointed out in the claim at the end of this specification.

In the drawings which form a part of this specification, and in which similar letters of reference refer to similar parts wherever they occur, Figure 1 is a side elevation showing a blindstitching attachment with my improved guide applied thereto in position on the head of a sewing-machine. Fig. 2 is a front elevational view of the parts shown in Fig. 1. In this view I show a piece of cloth properly folded under the presser-foot and guided to the needle to be stitched. Fig. 3 is a plan view showing a portion of the top plate of an attachment with my guide in place thereon. Fig. 4c is a side elevation of the parts shown in Fig. 3. Fig. 5 is a side elevation of the ide by itself looking at the inner side 0 the same, and Fig. 6 is a plan view of a plain presser-foot adapted for use with the guide.

My improved guide is especially adapted for use with a blindstitching attachment such as is shown in my application, Serial No. 77,088, in which a pusher pushes the cloth away from the needle at every alternate stitch, producing a zigzag row of'stitching, and in the use of which it is desirable to so guide the cloth to the needle that the needle will be prevented from passing entirely through the fold of the cloth from side to side, but will enter and pass out of the cloth on the same side thereof, producing a true blindstitching, as is fully described in the. said ap lication,

To tl fe front edge of the attachment Ai 6., the side nearest to the operator-I secure a plate B. This plate B is provided with two slots 6 I) and is held. against the side of the attachment A by two screws 6 6 which pass through the slots b b and engage in screwthreaded holes in the side of the attachment A, the said plate B being free to move transversely along the edge of the attachment A, being held against displacement by the heads of the screws b 6 The plate B is also formed with two upwardly-extending lugs B B A screw O, having a milled head, passes through the lug B and engages with the head (i of the guide D, which is provided with a screw-threaded aperture for the purose. The guide D consists of the plate hav ing the head. 01 at one end and a downwardlyextending flange of at the other end, the flange (i being so constructed and arranged that it passes down by the side of the attachment A next to the needle E and extends from a point nearly in line with the pusher A to a short distance beyond the front side of the attachment A. By turning the screw O by its milled head the guide-plate and its flange 61 may be moved upwardly and down wardly away from or toward the base-plate of the sewing-machine.

To the end of the attachment A opposite the needle E, I secure an upwardly-extending plate F, the upper portion of which is bifurcated, forming jaws ff. The lug B of the plate B is provided with a block B having a central screw-threaded aperture 6 An adjusting-screw G, provided with a milled head and having a circumferential groove or channel g in its head, passes between the jaws f f of the plate F, the j aws f f having a bearing in the groove or channel 9 and engages in the screw-threaded aperture 1). As this adjusting-screw G is held by the jaws ff and is turned the one way or the other by its milled head it carries the block B and conse quently the plate B, and the guide D and its flange (Z toward or away from the needle E, and in this manner adjustment may be made for sewing any thickness of material.

Instead of the resser-foot ordinarily used for the machine for plain sewing I employ a resser-foot such as shown in Fig. 6 having a recess X in its side next and opposite the needle E in order to receive the bulge of the cloth when the pusher A is extended and pushes the edge of the cloth away from the needle.

In carrying my invention into operation the attachment is secured to the work-plate of the machine in the usual manner by a setscrew. The cloth to be stitched is then'fold ed as shown in Figs. 1 and 2that is to say, a hem is first turned up and then the body of the cloth is carried back over the hem, leav ing the single layer of the cloth under the fold and projecting slightly beyond the fold.

'The cloth thus -folded is inserted under the resser-foot H with the fold against the side of the flange d of the guide D and the single layer under the said flange (1 which may be slightly raised from the work-plate of the machine for this purpose by turning the screw 0. The position of the flange d with respect to the needle E is determined by the thickness of the material to be stitched, it being necessary to so guide the cloth to the needle that the latter cannot pass entirely through the cloth in the fold from side to. side, but will enter and pass out of the same side, splitting or passing approximately 30 through the middle of the material forming the said fold. As hereinafter stated, my improved guide may be adjusted as desired with relation to the needle and to the presser-foot by simply turning the adjusting-screw G the one way or the other, so that the materials of any thickness and almost of any degree of thinness may be blindstitched.

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

In combination a base-plate, a horlzontally-adjustable plate held against one edge GEORGE JOHN STEVENS.
