GUIDE FOR SEWING-MACHINES.

Specification of Letters'Patent.

Application filed August 25, 1909.

Patented Get. at, 1910.

Serial No. 514,556.

To all whom it may concern:

Be it known that I, ABRAHAM L. RiclioL- sow, citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful lmprove-n'ients in Guides for Sewing-Machines, of which the following is a specification.

This invention comprehends certain new and useful improvements in attachments for sewing machines, and the invention has for its object a particularly convenient and eliicient guide that is designed to be carried by the presser foot and is adjustable relative thereto in order to guide the stitching and regulate the width of hems, tucks, or the like, the device being susceptible of being quickly applied to the presser foot or detached therefrom as desired.

A further object of the invention is a guide bar which is slidable transversely relative to a shoe which is adapted to be fitted frictionally on the toe of the presser foot, the guide bar being provided at one end with a gage for guiding the sewing and the shoe being capable of being reversibly fitted to the toe, whereby to support the on one side of the presser foot or the other according as occasion demands.

lVith these and other objects in view that will more fully appear as the description proceeds, the invention consists in certain constructions and arrai'igements of the parts that I shall hereinafter fully describe and then point out the novel features in the appended claims.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying drawing, in which:

Figure 1 is a perspective View of a sewing machine guide attachment constructed in accordance with my invention, and, Fig. 2 is a view of the parts detached.

Uoi'rresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

The invention consists essentially of a hollow shoe which is of flattened tubular form and is adapted to be titted frictionally on the toe of a presser foot of the conventional type. The shoe is preferably constructed of sheet metal and comprises a bottom plate 1,

upturned substantially parallel side plates 2, and a top plate 3. The end portions of the top plate are out free from the side plates and are turned perpendicularly upwardly to form opposed transverse lips Between these lips the top plate carries an upstanding threaded stem or post 5 on the extremity of which works a thumb nut 6. The stem 5 projects upwardly through a longitudinal slot 7 formed in a guide bar 8 which disposed transversely with respect to the shoe and is slidable across the top plate between the lips 4, the lips abutting the side edges of the guide bar to hold the same against any turning movement about the stem, as a pivot. At one end the guide bar is formed with a depending gage flange 9 which is disposed in the direction of the length of the shoe and is preferably extended terminally beyond the opposite side edges of the guide bar, as indicated at 10, the gage flange serving to guide the stitching and regulate the width of hems, tucks, or the like. For convenience the guide bar is graduated, as shown, so as to admit of the gage being supported at different known distances according to the requisite width of the hem, the guide bar being retained in such adjusted position by tightening the thumb nut 6 thereagainst.

Attention is particularly directed to the fact that the shoe is open at both ends, so that it may he slipped off of the presser foot and replaced thereon in reversed position to support the gage on the opposite side of the presser foot when occasion requires, this reversible feature rendering the device very handy. As the toes of presser feet are usually upturned to some extent. it will be observed that the gage flange will be supported in rearwardly inclined relation to the needle plate, so that one of the extended portions 10 will depend in close proximity to the cloth or other material without the liability of the gage catching in and possibly snagging the cloth as it passes over the needle plate. By extending the end portions of the gage beyond both side edges of the guide bar, the gage is maintained in operative relation to the needle plate when the shoe is fitted on the presser foot in the reverse position.

From the foregoing description, in connection with the accompanying drawing, it will be apparent that I have provided an improved guide attachment which admits of the sewing operation being more accurately and expeditiously accomplished. The guide possesses to a marked degree the characteristics of simplicity, and durability, and consists of comparatively few parts and is therefore not likely to get out of order. Furthermore, the device is susceptible of being easily and cheaply manufactured so as to be placed on the market at a price not too great to prevent its general adoption.

Having thus described the invention what is claimed as new is:

l. A guide attachmentfor sewing machines comprising ahollow shoe adapted to be fitted 011 the toe of the presser foot and consisting of a top, bottom, and sides, the top being provided with upstanding transverse lips, a threaded stem upstanding from the top between the lips, a guide bar slidable transversely across the top between the lips, the guide bar being formed with a longitudinal slot through which the stem projects,

a thumb nut working on the stem to bind the guide bar in dn'i erent ad usted pose;

tions, and a gage carried at one end of the guide bar.

2. The combination with a presser foot having an inclined toe, of a guide attachment including a hollow shoe removably fitted to the toe, a guide bar carried by and adjustably connected to the shoe and pro jecting laterally at one end on one side of the toe, and a gage provided at said end of the guide bar and having its end portions projecting beyond the side edges thereof, the gage being similarly inclined to the toe with one or its projecting ends depending in operative relation to the needle plate, the shoe being adapted to be fitted to the toe in reverse position to support the gage on the other side of the presser foot with the other projecting end of the gage in operative relation to the needle plate.

In testimony whereof I affix my signature in presence of two witnesses. 7
