6 Claims.

This invention relates to work guide for sewing machines. It is particularly directed to an adjustable guide adapted to be attached to the work plate or" a sewing machine to guide bands, ribbons or other work during the sewing operation, when making tucks and for the like purposes.

In making tucks, the material is folded and stitched longitudinally close to the fold. Difiiculty has been found in guiding the folded material so that the stitching can be made close to the fold. An object of the present invention is therefore to provide a guide of the character described having improved means for guiding the folded material in such a manner as to permit stitching very close to the folded edge thereof, whereby to facilitate the making of tucks in the material.

A further object of this invention is to provide a guide of the character described which is adjustable for bands of various widths.

Another object of the present invention is to provide a guide of tile character described, formed with an upwardly extending fin or proiec'tion adapted to engage one edge of the material to be sewed, said fin or projection being so constructed that it may be received within the slot of the lpresser foot, said guide being adjustable on the work plate of the sewing machine to also permit engagement of said fin or projection with an outer sideof the presser foot or beneath the upturned toe portion of the :presser foot.

Still .anotherobject of this invention is to proide a guide of the characterdescribed having an adjustable work engaging member which may be fixed to the guide in various adjusted positions to accommodate bands or work of different width, said guide being so constructed that the adjustable member may be moved out of the way when not in use, the guide furthermore being formed with a fixed work engaging member to be used for guiding work of predetermined width, when the adjustable guide is not in use.

Yet another object of this invention is to provide a guide of the character described, which may be attached to the work plate in various adjusted positions.

A still further object of this invention is to provide a strong and durable guide of the character described, which shall ,be relatively inexpensive to manufacture, easy to assemble, adjust and manipulate, and yet practical and efficientto a high degree in use.

Other objects of this invention will in part-be obvious and in part"hcreinafterpointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement 0f parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 2 is a front elevational view of the structure shown in Fig. 1;

Fig. 3 is a cross-sectional view taken on line 33 of Fig. 1;

Fig. l is a partial top plan view taken below the presser foot and illustrating the method of guiding the material along the guide fin during the sewing operation;

Fig. 5 is a cross-sectional view taken on line 5-5 1 Fig. l; and

Fig. 6 is a cross-sectional view taken on line 5-45 of Fig. 1.

Referring now in detail to the drawing, H1 designates the work plate of a sewing machine, and H designates a presser foot of usual construction used therewith, while numeral 12 designates an improved work guide l2 embodying the invention.

The work plate ii] is formed with a pair of parallel, longitudinal slots or openings l4 and 1-5, in which are located the oscillating feeders Ma and l5a respectively.

As shown in the drawing, slot H3 is longer than slot 55. The work plate is also formed with an opening H, aligned with slot is and located in front thereof. Said slot H has an offset portion is extending toward slot l4 and through which the needle 2i] passes during the sewing operation.

The presser foot H is formed with a longitudinal slot 22 and has portions 23 and 2.4 on opposite sides pfs'aid slot. Portion 23 is in alignment with thejeed member Ma, whereas presser foot portion 2A is in alignment with the feed member 15a. As shown in the drawing, the needle 2d passes .through theslot 22 in the presser foot. The front ends of the toes'of presser foot portions 2-3, .24 are inclined upwardly and forwardly.

The work plate .I ii, the presser foot-l I, the feeds Ma and la and the needle 20 as described above are of usual and well known construction.

The guide l2 embodying the invention comprises a member 30 generally in a direction inclined rearwardly and to the right relative to front edge of the work plate 10, as shown in Fig. I. Said member 30 comprises a fiat, L-shaped portion 3| lying on the work plate It), and having a longitudinal portion 31a and a portion 3lb extending forwardly from the right end of portion am. Extending from portion 3") is an integral, horizontal guide rail arm 32 offset upwardly from said fiat portion 3|, and connected to said portion 3 lb, by a shoulder 33. Arm 3 2 is parallel to portion 3la and spaced therefrom by slot 4 and extends therebeyond to the left. i

Portion 3| has at the rear of its left end, an edge or shoulder 35, perpendicular to the front edge of work plate i9 and adapted to contact one side of the presser foot H. Said portion 3la is furthermore formed with a portion 35 disposed forwardly of shoulder 35 and extending beyond said shoulder. Extending upwardly from said portion 35, is a fin or fixed guide stop or projection 3'! parallel to said shoulder 35.

The projection 31 thus likewise extends in a direction at right angles to the front edge of the work plate l0, and is adapted to be received within slot 22 to contact the inner edge of presser foot portion 24. Thus, the distance between the projection 31 and shoulder 35 is substantially equivalent to the width of the presser foot portion 24. Projection 31 has an upwardly and forwardly inclined upper edge 31a of substantially the same inclination as the toe portions of the presser foot, for the purpose hereinafter appearing.

Arm 32 is also fiat and disposed in a horizontal plane somewhat above the plane of the top surface ofthe work plate Ill. The outer end of arm 3lis bent upwardly and backwardly, as at 4|, to form a fixed guide stop 42 when guiding a work of a predetermined width, which width is equivalent to a distance between the projection 31 and the stop 42, in a direction parallel to the front edge of the work plate.

slidably mounted on arm 32 is a movable and adjustable guide stop 45. The guide stop 45 has a sleeve 46 slidably receiving the arm 32. On arm sleeve 46 is an adjustable screw 41 to fix said adjustable stop in any desired adjustable position. Extending from sleeve 45 is an upwardly turned guide member 48, parallel to the projection 3?. scale 55 which is calibrated to give the normal width of the work guided between the projection 31 and the adjustable guide stop 45.

It will be noted that the work is engaged at one edge by the projection 31 and at the other edge by the guide stop 45. The guides for the opposite edges of the work are thus not aligned with each other, so that the work is guided at different longitudinal points at opposite edges thereof, thus facilitating guiding of the material during the sewing operation.

If it is desired not to use the adjustable guide 45, screw 41 may be loosened and member 45 then moved to the dotted line position shown in Fig. 1, within slot 40, so as to be out of the way.

The work plate I0 is formed with a pair of tapped holes 56 and 51, either one of which can receive a screw 58 with a wide head. Portion 3| of member 30 is formed with a pair of parallel, longitudinaI slots 59, 60. The screw passes through one of the slots and is screwed into one Arm 32 may be marked with a of said tapped openings. Upon turning the screw, the head thereof will press the guide plate firmly against the work plate I!) to hold it against movement.

It will be noted that the guide member [2 can be adjusted, by loosening the screw 58, to bring the projection 31 either within the slot 22 as shown in full lines in Fig. 1, or against the outer side of the presser foot as shown in dotted lines in Fig. 1, or beneath the toe of the presser foot, as is also shown in dotted lines in said Fig. 1,

or to other positions.

When the projection 31 is within the slot 32, the work may be stitched very close to its edge, since there is very little distance between the plane of the projection 31 and a plane parallel thereto and passing through the needle 20. Thus, with a guide embodying the invention, tucks may be made by folding a piece of material longitudinally and then stitching the folded piece with the folded edge contacting the projection 31 during the stitching operation, thus making a line of stitching close to the fold. When the material is unfolded, a fine tuck will be produced. The improved guide member l2 may be used for guiding ribbons, hat bands, or any other similar work during the stitching operation. If desired, the guide 3'! alone may be used.

It will now be understood that the positions of the guides for the opposite edges of the work maybe adjusted relative to the line of stitching.

If desired, the turned back portion 42, 4| may be omitted.

The advantages of constructing the guide to lie at an inclination to the presser foot is that the rail arm projecting forwardly and to the left, is out of the way of the presser foot. Furthermore, th projection 31 may be easily adjusted by moving the guide about the attached screw 58. Thus, the projection 31 may be moved forwardly of the presser foot so as to be out of the way of said foot. Such adjustment would not be readiy accomplished if the guide were at right angles to the presser foot. Furthermore with such construction, the projection 31 can be placed close to the needle so as to aid in producing a fine tuck.

-In making bands for the crowns of uniform caps, such as policemen or firemen caps, or the like, itis necessary to make a tuck above the lower edge of the band. Heretofore, it was necessaryto mark a line on the band where the tuck was to be made in order to have the tuck at a particular height above the lower edge of the band. With the improved guide herein disclosed, it is possible to make such a tuck without necessity for marking the band before the stitching operation. The reason is that the improved guide can be adjusted to the desired width of the band and-the guide will then guide the band through the sewing operation so as not to vary the line of stitching relative to the edges of the band.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
