EDGE-GUIDE ATTACHMEN '1 F03, SEVJING-IVIACHINES.

Specification of Letters Patent.

Application filed April 2'7, 193.6.

To all whom it may concern:

Be it known that I, ARTHUR W. DUDLEY, a citizen of the United States, residing at Marlboro, in the county of Middlesex and tate of Massachusetts, have invented cer tain new and useful Improvements in Edge- Guide Attachments for Sewingdslachines; and do hereby declare the following to he a full, clear and exact description of the inventi 11 such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an edge guide attachment for sewing machines which are used in the fitting room of a shoe making establishment, in the operation of top stitching of shoes and the primary object of the invention is to provide an attachment specified which is constructed so that it will be simple and easy for the operator to keep on the edge on the top of the upper of the shoe and thereby get an even regular line of stitching insuring good and uniform work.

Another object of this invention is to provide an attachmeit or guide as specified which can be instantly thrown out of an operative position the will of the operator, should shoe being worked upon require a bar or r oforcement of any kind on the strap and which when thrown into an inoperative position will permit of a clearance of practically two and one-half inches so that it will not in any way bother the operator of the machine A further object of this invention is to provide a guide as specified which is constructed for allowing the needle to run as close to the edge of the top of the shoe as the operator may desire.

ll ith the foregoing and other objects in riew this invention consists in such novel features of construction, combination and arrangement of parts will he hereinafter more fully described, illustrated in the companying drawing and claimed.

In describing the invention in detail reference will he had to the accompanying drawing wherein like characters designate like Patented Apr. 2a, 1917.

Serial NO. 93,947.

It i g. 2 is an end view of the guide.

Fig. 3 is a top plan View of the guide showing the same swung into an inoperative position, and

Fig. l is a cross section through the guide.

Referring more particularly to the drawing, 1 designates the base or attaching plate of the guide which is provided with a slot 2 and a groove 3 which extends inwardly from one end of the plate and is adapted for receiving a boss 4: which projects downwardly from the under surface of the pivoted supporting block 5. The supporting block 5 is pivotally supported by a pin 6 which is attached to and projects'upwardly from the uppersurface of the attaching plate 1. The block 5 is mounted upon the pin 6 for vertical movement "ith respect thereto, and a spiral spring 7 is coiled about the pin and engages the upper surface of an arm 8 which is mounted upon the upper surface of the block 5 and the under surface of a washer 9 which washer is mounted upon the pin 6 and is held in place by means of a cotter pin or the like 10. The spring 7 tends to force the under surface of the block 5 in engagement with the upper surface of the attaching plate 1. at all times and it also forces the block downwardly so that the boss 4 will be seated in the groo e 3, when the attachment is in .an operative position for preventing accidental rotary movement of the block and the structure carried thereby.

A cam 1]. is pivotally connected to the lolock 5 as shown at 12 and it has a thumb piece 13 formed thereon, by means of which the cam is rocked. The cam 11 is provided with a rounded shoulder 14 which engages the upper surface of the attaching plate 1 so that when the thumb handle or rest 13 is moved downwardly, the rounded shoulder 14 will ride upon the upper surface of the plate 1 and force the block 5 upwardly out of engagement with the upper surface of the plate 1 so as to permit the block to he swung into a transversely extending position as illustrated in Fig. 3 of the drawing. A pin 15 is carried by the attaching plate 1 and it limits the pivotal movement of the block 5.

The arm 8 is provided with an opening 17 formed therein, which opening receives the rolled end 18 of a guide arm 19. A pin 20 extends through the rolled end 18 and through the plate 8 for pivotally connecting the guide arm 19 to the guide arm 8. The arm 19 is provided with a slot 21 formed therein which receives a guide pin 22 carried by the arm 8 adjacent to its outer end. A set or thumb screw 23 is threadably carried by the guide arm 19 and its under or inner end engages the upper surface of the guide arm 8 for holding the arm 19 in various adjusted pivotal positions with respect to the arm 8. A spiral spring 24c is coiled about the thumb screw 23 and engages the upper surface of the guide arm. I

A spring or resilient wire 25 has one end attached to the upper surface of the arm 8 by means ofa screw 26 and its other end extending transversely across and engaging the ppper surface of the arm 19 as shown at 2 The outer end of the guide arm 19 is bent downwardly as shown at 28, and further as shown at 29 to provide a portion 30 which extends substantially at right angles to the surface of the plate 1 and also the arm 8. The outer surface of the transversely extending portion 80 is provided with a groove 31, which forms a guide for the needle of the sewing machine when the guide is adjusted so that the article being sewed will be stitched very close to its edge.

The edge guide is adjustably attached to the table A of a sewing machine by means of thumb screws B which extend through the slot 2 and the angled end 30 of the guiding arm 19 is positioned so that the edge of the article being sewed will engage the outer surface of the angled end 30, thereby maintaining a uniform distance between the edge of the article being sewed and the needle C of the sewing machine. The distancebetween the end 30 and the needle C may be varied as desired by loosening the thumb screws B and sliding the attaching plate 1 either toward or away from the needle C as desired.

Then it is necessary to sew inwardly from the edge of the article being worked upon, the cam 11 is rocked through the medium of the thumb piece 13 and the block 5 is rotated or swung about on the pin 6 for positioning the guiding arm 19 and the plate 8 at right angles to their normal operative positions.

From the foregoing description taken in connection with the accompanying drawing, the advantages of construction and of the method of operation of the improved edge guide attachment for sewing machines will be readily apparent to those skilled in the art to which this invention appertains, and while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions'provided such alterations are comprehended within the scope of what is claimed.
