Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed March 31,1905. Serial No. 253,125.

To all whom it may concern.-

Be it known that I, J OHN S. JACOBS, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Embroidery Attachments for Sewing-Machines, of which the following is a specification. 1

This invention embodies a simple attaching device adapted to be appliedto sewingmachines for embroidering purposes.

The invention .is substituted for the usual presser-foot provided upon the machine and includes a spring presser-foot arranged to bear lightly against the material being embroidered and permitting of moving the material in any direction, so as,,to properly work the design which is being embroidered.

The attachment is very durable and is adapted to be secured to the standard of the machine which carries the needle-bar, the construction ofthe attachment admitting of securing the same to the various forms of machine parts at present most commonly used.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which Figure 1. is a perspective view showing the invention applied. Fig. 2 is a side elevation of the attachment comprising the invention. Fig. 3 is a front elevation. Fig. 4 is a top plan view.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Describing specifically .the attachment which constitutes this invention, the numeral 1 indicates a bar, one end portion of which is bent to form a sprin 2 and thence extended in an approximate y horizontal direction from the spring 2 to form an arm 3. The outer extremity of the arm 3 is bent downwardly and formed into a loop 4, constituting a pressenfoot, through which the needle 5 of the machine is adapted to operate. The extremity of the arm 3 adjacent the loop 4 forms a spring-finger 6, which is normally in contact with a side of the arm 3 and which makes the attachment self threading in a manner which will be obvious. The peculiar construction of the foot 4 is such as to prevent hanging or frazzling of the silk which is being embroidered into the material or cloth being operated up on. The bar 1 and the arm 3 are arranged approximately in parallel re lation one above the other, and the outer extremity of the bar 1 is coiled. to form a loop 7, through which the needle 5 passes also, the loop 7 being disposed approximately in vertical alinement with the foot 1.

The attachment is preferably made of a single length of material, such as spring-wire, and is projected laterally from the loop portion 7 to form an extension 8, bent at its outer end to form a spring 9, and thence extended from the spring 9 to form a spring-engaging member 10. The engaging member 10 is bent or deflected between its ends to form a seat 11, arranged to receive a boss 12, which usually extends from the needle-bar 13 of the machine and through which passes the screw 14, which holds the needle 5 in place. The seat 11 when engagedwith the part 12 affords an interlocking connection between the attachment and the portion of the machine to which it is applied, which firmly holds the attachment in place, the needle 5 operating through the loop portion 7 and the foot 4. The extremity of the spring-engaging member 10 opposite that at which the spring is formed extends laterally and is bent to form a finger-piece 15, by which the member 10 may be readily manipulated in engaging the same with the part 12 or disengaging the same to facilitate removal of the attachment.

It will be understood that in applying the attachment the presser-foot ordinarily employed upon the machine is previously removed and it is not necessary to change the bottom tension, and the top tension must be sufficiently loose to prevent the upper thread from jerking the bottom thread. through the cloth which is being embroidered. In embroidering, the ordinary hoop-holder is preferably used to hold the cloth beneath the needle and enables the operator to shift the cloth in all directions in the embroidering operation and vary the length of the stitches as necessary. The spring 2 exerts sufficient pressure 011 the foot 4 to prevent the cloth from slipping while the shuttle performs its function in making the stitch, and the loop portion 7 of the bar 1, through which the needle 5 passes, is preferably made of several coils in order to increase its strength and to prevent the same from getting out of shape. The formation of the device is also such that the same may be readily applied to any style of needle-bar.

The needle-bar 13 rests upon the loop portion 7 of the attachment, and the bar 1 is deflected upwardly adjacent the base of the portion 7, this being essential in order that the presser-foot 4 may be prevented from slipping forward and breaking the needle 5.

Having thus described the invention, what is claimed as new is 1. An embroidery attachment comprising a length of Wire bent to form the loop portion 7 adapted to receive the needle of a sewing-machine, said wire being extended from the loop portion 7 and formed into the spring 2, and thence extended from the spring 2 to form the approximately horizontal arm 3, the outer end portion of said arm being bent downwardly and thence outwardly to form the horizontal loop 4 constituting a presserfoot, the extremity of the arm 3 adjacent the loop 1 being bent upwardly from the loop alongside the arm 3 and terminating at a side of the arm, in contact therewith, some distance above the loop 4, and means for securing the attachment to a machine.

2. As a new article of manufacture, an embroidery attachment for sewing machines consisting of a single length of wire 1 having an end portion formed into the loop portion 7 for the insertion of the needle extended laterally from said loop portion to form the extension 8 having the outer end thereof bent to form the spring 9 and extended back toward the loop portion to form the spring-engaging member 10 deflected between its ends to form the seat 11 and having its extremity projected laterally to form the finger-piece 15, the wire 1 being extended from the loop portion 7 and formed into the spring 2, and thence extended from the spring 2 to form the approximately horizontal arm 3 having its outer end bent downwardly and extended to form the horizontal loop 4 constituting a pressenfoot, the extremity of the arm 3 adjacent the loop 4 being bent upwardly therefrom and terminated at a side of the arm 3.

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