GUIDE FOR A SEWING MACHINE Filed Dec. 12, 1958 INVENTOR. EDMOND W. LOISELLE ATTORNEYS United States Patent 3,954,367 GE FOR A SEWING MAC Edmond W. Loiselle, Diamond Hill Road, Cumberland, RI. Filed Dec. 12, 1958, Ser. No. 779,996 8 Claims. (Cl. 112152) This invention relates to a guide for a sewing machine particularly designed for use in guiding the rope-like braid cord from which rugs are made by sewing the cord in spiral or pseudo-spiral formation.

Heretofore in the sewing of rugs of the type above indicated at the beginning of the formation of the rug where the turn of the rope-like material is partially bent through substantially 180, the sewing has sometimes missed the rope formation as it is fed in or caught the same only on the very edge.

One of the objects of this invention is to provide a guide which will enable the operator to force the rope-like material even at the sharp turns into such a position that the sewing will extend substantially inwardly from the edge of the rug and get a good grip to hold the material in the position desired.

Another object of the invention is to provide a guide which although performing this advantageous object may be retracted, so that as the rug is finished the guide may be pulled out of place to enable the sewing to be more advantageously accomplished.

Another object of the invention is to provide a guide which may be adjusted to accommodate different diameters of roping which go to form the rug.

Another object of the invention is to provide a guide which may be easily disassembled for cleaning purposes.

Another object of the invention is to provide a guide which will prevent the finished portion of the work from riding up away from the plate which guides it in the vicinity of the sewing operation.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

in the accompanying drawings:

FIGURE 1 is a top plan view of a fragmental portion of a sewing machine illustrating a rug which has been partially formed and of the guiding of the rope-like form which goes to make the rug in my attachment.

FIGURE 2 is a sectional view on substantially line 22 of FIGURE 1 with the work omitted.

FIGURE 3 is an exploded perspective view of portions of the guide shown as separated to bring out the different parts thereof.

FIGURE 4 is a sectional view on substantially line 4-4 of FIGURE 1 showing the resilient means for holding the plate in one position.

FIGURE 5 is a plan view of a portion of a rug.

In proceeding with this invention, I modify the throat plate of a sewing machine by providing a guiding slot or recess therein, and I further provide a plate which rests upon the surface surrounding the throat plate with a thin fin-like portion upstanding from the plate and extending beyond an edge of the guide plate and over the throat plate and in position so that a tongue from this fin will enter the recess of the throat plate for guiding the guide plate in its movement. And I also provide an adjustable fin on this guide plate for varying the distance between fins and for supporting the work at the point of sewing in a firm position. This plate is further guided by slots and shouldered screws.

With reference to the drawings, designates a throat plate of the sewing machine which is set into a surrounding supporting surface 11 of the sewing machine so as to be substantially parallel or flush with the surface. It is 3,54,3h7 Patented Sept. 18, 1962 held in this surface by screws 12. The presser foot of the sewing machine designated generally 13 is reciprocatingly mounted on the plunger 14 and the needles 15 and 15' of the machine passes through the bifurcated portions 16 of this foot.

Upon this supporting surface 11, I have provided a guide plate designated generally 17 which is a generally fiat sheet metal plate with a projecting portion 18 or which might be thought of having a cutaway portion 19 when viewed in plan. From the edge of this projecting portion 18, there extends upwardly a work pressing fin 20 which projects beyond the edge 21 of this portion 18 and is provided with a tongue 22 which extends downwardly and enters a slot 23 in the throat plate 10. This slot 23 extends in the direction of feed of the work and enables the plate 17 to be guided by this tongue and slot arrangement in this direction of feed. However, for further guiding the plate, it is slotted as at 24 and 25 through which slots there extends

shouldered screws

25 and 27 with these shoulders in engagement with the edges of the slot and serving to space the screws 26 from the table into which they are threaded so as to further guide the plate for reciprocating movement on the supporting surface 11.

A second fin 36* is bent upwardly from a second smaller plate 31 along its edge and is flared backwardly as at 32 and 33 and is located in spaced relationship but generally parallel to the fin 20. This fin 39 may be moved toward and from the fin 26 by means of an upstanding threaded block 35 and a screw 36 which has threaded engagement with the block and has a collar 37 which is slotted as at 38, the slot of which rests in a closely fitting recess 39 in the yoke 40 extending upwardly from the plate 17, thus holding the screw against axial movement. A handle 41 serves to rotate the screw 36 to cause move ment of the plate 31 and its fin 3t and a spring 42 serves to tension the same and hold it in adjusted position. A slot 43 is provided in the plate and a shouldered screw 44 passes through this plate into the lower plate so as to guide the same. In order to retain the plate 17 in the forward position, I have deflected the plate as at 45' to provide a recess 45 in the under surface of the plate as shown in FIGURE 4 and positioned a ball 46 behind which there is spring 47 in a recess in the stock 48 which forms a surface 11 so that when the plate is pushed forwardly or upwardly as shown in FIGURE 1 with the fin 20 extending in between the bifurcated foot, the plate will be held in this position.

A lip 55 is formed on the fin 20 beneath which the work extends and which prevents the work from raising away from the supporting surface 11.

In operation of this guide it is necessary to withdraw the plate 17 from a position in which the forward end of the fin 20 extends into the bifurcated foot in order that the braid may be pushed in beneath the foot. ln the showing in FIGURE 5 with the plate retracted, the forward end of the fin 20 is positioned in substantially the bight of the material indicated at 50 and then the braid is pushed forwardly and will be held in its forward position by the ball 46 and sewing will continue as shown down the junction between the bight of material around the turn as shown at 51. Then as the material is nearing its end, the plate will again be retracted and will allow the finishing end to be sewn to the convolution which has been already coiled in position. This movement of the plate to move the fin 20 into an operating position thus affords a versatility of operation which is very advantageous. The plate may be moved from its held position by merely pulling outwardly on the plate or downwardly as shown in FIGURE 1 when the pull will release the plate permitting it to be moved to its outer position. During this operation the lip 55 will prevent the work from riding up too high along the fin 20. If the prevent the work from being crowded to the left as seen in FIG. 1 and thus would prevent the stitch from being out of desired position, or if the braid is of lesser diameter, it will prevent the braid from being moved to the right as seen in FIG. 1 to prevent the stitch from being out of position to the other side.
