Filed Get. 29, 1963, S81. No. 319,805 2 Claims. ((11. I12--152) This invention relates to an attachment for eswing machines, which attachment is useful in sewing one or more pieces of decorative material, as lace, insertion, edging, for example, to or over a base or principal material.

An object of the invention is the provision of a device, of the character mentioned, which may be adapted to sewing decorative material of different widths, at different sewing positions relative to the principal material, and also adapted to regulate the distance between rows of stitching and the distance of such rows from the edges of the decorative material.

Another object is to provide one device of the character mentioned which will do the work of many devices as heretofore made.

The drawings illustrate one embodiment of the invention, and in these:

FIGURE 1 is a plan View of the device;

FIGURE 2 is a bottom plan of the major portion of FIG. 1, as said portion appears after turning 180 degrees;

FIGURE 3 is a view of the main part of FIG. 1 turned forwardly through 90 degrees, most of the finger guides and fasteners therefor being removed for clearness;

FIGURE 4 is a side view of a goods guide;

FIGURE 5 is a plan view of an adjustable bar carrying the goods guide;

FIGURE 6 is a plan view of a bar for adjustably securing the frame of the attachment indirectly to the foot bar of the sewing machine;

FIG. 7 is a view of FIG. 6 from the right;

FIGURES 8 and 9 are respectively side and edge views of a connector for adjustably securing the goods guide bar of FIG. 5 to the frame of the device;

FIGURE 10 is a plan view of one of the movable finger guides which are held in the frame of the device;

FIGURE 11 is a side view of FIG. 10 from the right;

FIGURE 12 is a section on line 1212 of FIG. 1;

FIGURE 13 is a plan view of one of the several similar screws which fasten the finger guides in selected positions in the frame of the device;

FIGURES 14 and 15 are respectively plan and headend views of a screw which tightens the bar of FIG. 5 to a connector secured to the right hand end of the main portion of the device; and

FIGURES 16 and 17 are respectively plan and headend views of a screw used for adjustably securing the bar of FIG. 6 to the left end of the frame of the device and also for securing the goods guide to the right hand end of said frame.

Referring to the drawings for a detailed description, the numeral 20 indicates the frame of the device. The frame comprises an upper part 21, and a lower part 22 secured at its ends by screws 23 (FIG. 2) to the upper part. Between the contacting ends, the said parts are spaced, as indicated in at 24 (FIG. 3). The upper part 21 has an elongate vertical slot 25 (FIG. 1) between its ends, which slot extends through said upper part. The upper part of said slot is wider than the lower part, to provide a ledge 27 around the slot.

A plurality of similar, elongate guide fingers 31 (FIGS. 1, 2, 10, 11 and 12) pass horizontally through space 24, being slightly thinner than the space, and extend from a line a little in front of the frame 20 to somewhat beyond the back thereof. FIGURES l0 and 11 show the finger guides 39 as having a boss 31 extending from one face Patented Aug. 3, I965 thereof, and as having a hole 33 extending through the boss and transversely through the finger from face to face, the defining parts of the hole being threaded (FIG. 12). The finger guides being in the space 24, the bosses 31 extend upwardly into the lower and narrower part of the longitudinal slot 25 of the upper part 21 of the frame, the upper surfaces of the bosses then being coplanar with the upper surface of the ledge 27. The finger guides are slidable in the spacing 24 lengthwise thereof to selected positions and are fixed in such positions by thumb screws 35 (FIG. 13) which extend above the frame. The screws 35 each have a head 35A, a reduced portion 35B adjoining the head, and a threaded end portion 350. The threaded portion of each screw engages the threads (FIG. 12) in a guide 3t) and in the boss 31, and the lower or inner end surfaces of the reduced portions 35B tighten against the ledge 27 to hold the guide in place. i

The guides are separated to the width of the decorative material to be sewed onto the base material, and one or more strips of the former material are each run between a pair of guides, being pulled forward by and with the base material. The decorative material varies in width. For the wider material, some of the fingers may removed if necessary.

The frame 20 is adjustably secured to the sewing machine, so as to be moved to the right or left relative to the needles, and is also adjustable to change its distance in front of the needles, as required by different materials, in which position it functions, and is further adjustable in a swivel movement, by which swivel movement it may be tilted by raising or lowering the rear ends of the fingers to give a clear View for inspection of the quality of the sewing as the machine is running. The means for providing the mentioned adjustabilities are as follows. A screw 49 (FIGS. 16 and 17) engages the threads in a recess 39 (FIG. 3) formed in the left end (FIG. 1) of the frame 20, and is adapted to tighten to the frame an L-shaped bar 41 (FIGS. 1, 6 and 7). The bar 41 comprises a portion 41A which is parallel to the frame, and a portion 418 at right angles thereto. The portion .113 (FIG. 7) widens at its forward end to allow an elongate slot 44, through which slot the screw 4%) extends, the head of the screw bearing against the adjacent material when tightened. The portion 41A of the bar 4-1 is adjustably held in a clamp 47 so that it may be moved to the right or left, thereby moving the whole device in the same direction, whereby the finger guides may be properly placed relative to the needles. The clamp 47 is secured to the foot bar 48 of the machine by means of thumb screw 49.

The device includes a goods guide (FIGS. 1 and 4) which limits the right hand edge of the goods as it runs through the machine. This guide is screwed onto one end of a bar 56 (FIGS. 1 and 5) which is adjustably fixed in a clamping connector 58 (FIGS. 8 and 9), so that it may be moved to the right or left, according to the position desired for the edge of the goods. The guide 55 has a straight edge (FIG. 4) which rests on the machine, and the bar 56 has its outer end portion 56A bent at an angle to the main portion to provide a thumb piece for adjusting the bar. The clamping connector 58 (FIGS. 1, 8 and 9) has an elongate aperture 64} at one end so that it is adjustably secured to the right hand end of frame 26 (FIG. 1) by a screw 61, which is similar to screw 40 (FIG. 16), screw 61 passing through aperture of connector 58 and into the threaded recess 59 (FIG. 3) in the right end of the frame. The other end of the clamping connector 53 is split (FIG. 8) to provide opposing parts which are drawn towards each other by a screw 63 (FIGS. 1, 14 and 15) which passes through threaded aperture 65 and its aligned aperture 67 of said parts. The two parts formed by the split have opposed semi-circular notches 53 (FIG. 8) to form a round aperture which t V 35 r r receives the bar 56. By the construction described, the goods guide may be raised relativeito the other parts of the device when necessary, and may be moved to the right or left, and also allows the frame to be placed, and left in, a tilted position while the goods guide proper rests on the goods. Further, the elongate slot 69 allows the guide to be moved towards and away fromthe frame.
