PRESSER-FOOT Application filed July 30,

To all whom it may concern:

Be it known that I, F RANOIS S. Jones, a citizen of the United States, residing at lVest New Brighton, Staten Island, in the county of Richmond and State of New York, have invented new and useful Improvements in Presser-Foot Attachments, of which the following is a specification.

This invention relates to a device for at ta'chment to the presser-foot of a sewing machine and has for its primary object the provision of a means for guiding the presser foot 'in a plane parallel to the marginal edge of the work, whereby, the stitching is evenly spaced from said marginal edge.

Another object of the invention is the provision of a device which is detachably connected with a presser-foot so that the same may be readily removed and another substituted therefor when it is desired to change the distance between the marginal edge of the work and the stitching.

A further object of the invention is to provide a device which is yieldable in order to adapt itself to various thicknesses of materials.

A still further object of the invention is to provide a device of the type mentioned which is stamped from a single piece of material thereby rendering the same simple in construction, cheap of manufactureand highly efficient for the purpose intended.

With these and other objects in view, the invention resides in the certain novel construction, combination and arrangement of parts, the essential features of which are hereinafter fully described in the specification, are particularly pointed out in the claim, and are illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a presserfoot with my invention applied thereto.

Figure 2 is a transverse sectional view on V the line 22 of Figure 1.

Figure 3 is a horizontal sectional View on the line 3-3 of Figure 1.

Figure 4 is a detail sectional view on the line 44 of Figure 1.

Figure 5 is a perspective view of my invention per see.

It is my aim to produce a device which will permit accurate and uniform stitching by means of a sewing machine, especially by beginners of this particular work while PATENT OFFICE. j

operating at a high rate of speed. Also the invention reduces the amount of eye-strain usually required in stitching, for the reason that the operator is not compelled to constantly keep his eyes on the work, butmay feed the work through the machine by feellng.

Referring more particularly to the drawing, the-reference numeral 10 designates a resser-foot of the usual well-known construction for use in connection with single needle sewing machines. The resser-foot includes a shank 11, and a pair of spaced toes 12and 13 in the form of furcations. The toei 12 is shorter than the toe 13, and it is to this toe that a portionof my device is attached. 1

My device is shown at 14 in itsentirety and the same is shown as stamped from a single piece of flat material, coiled at one end to provide a horizontal portion 15 having formed thereon a finger 16 for insertion in a slot 17 provided in the front wall of the shank 11. The free end of the material is bent downward to form a hook 18 for co-action with a lug 19 extending outwardly from the side of the shank 11. The structure so far described serves as an attaching means for connecting the device to the Presser-foot. The other end of thedevice is adapted to co-act with the small toe 12 of the presser-foot as clearly shown in Figures 1 to 3 of the drawing. This endof the material is provided with a pair of downwardly bent walls 20 and 21, the wall 20 being slightly greater than the height of the presser-foot 10, and adapted to straddle the toe 12 so as to dispose the wall 20 in close contact with the inside of the toe and within the space between the toes 12 and 13. The

the edge 23. It will be seen that when the device is attached in the manner described, the guide wall 20 is permitted vertical movement against the tension of the coiled portion of the material so as to adapt itself to materials of various thicknesses. This feature being clearly shown in Figure 2 of the drawing. The thickness of the wall 20 acts as a gage for spacing thestitching 25 from theedge 23. In other words when it is desired to space the stitching further, away from the side edge, it'w'ould be'necessaryto substitute a devlce whose'wall 20 was of a lesser thickness so as to dispose the needle slot 26 further away from the edge 23,

and if a smaller space between the stitching and the edge is desired, it would be necessary to substitute a device whose wall 20 Was of greater-thickness so as to dispose the needle has been" clearly set forth and a further description of the same is not deemed neces-' sary.- It will be understood thatibyg'uiding the presser-foot in a line parallel to the marginal edgeof a piece'ofwork, an accurate and neat job of stitching. will be produ'ceeh and the necessity of constantly straining the eyes with an endeavor to make sure that the stitching is ten made uniformly P V straight is dispensed wit.

While I have shown and described what is deemed the best embodiment-of myinven- '7 f tion I wish it to be understood that changes,

alterations and modifications asv come within the see e of the appended claim may be resorte to. when desired.

An attachment for a presser foot of a sewing machine including a longitudinally curved resilient strip, a laterally extending base carried thereby at one'end and adapted to be 'receivedin-"a slot provided in the shank of the presser foot, rounded forwardly projecting guides carriedby the opposite ends of the strip and adap'tedto slide along the; longitudinaliedge of the work .bein
