Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed March 4, 1910. Serial No. 547,262.

To all whom it may concern:

Be it known that I, JOHN D. KARLE, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Embroidering Attachments for Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawlngs.

This invention relates to spring-actuated attachments adapted to be easily attached to or detached from the needle-bar of a sewing machine, and has for its object to improve that class of devices commonly termed embroidering attachments.

The present construction, like the earlier devices, is controlled to release its pressure on the material as the needle is withdrawn therefrom, thus permitting the material to be manually shifted bet-ween the successive stitch formations.

Owing to the simple character of the device herein described, only that portion of the stitch-forming mechanism to which the attachment is applied has been illustrated.

Referring to the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a view in elevation of the needle-carrying bar provided with the improvement, the cloth-presser being shown in the position which it occupies when the needle is out of the fabric; Fig. 2 is a like View, showing the cloth-presser raised in opposition to the resiliency of its actuating spring, as when the needle is in the fabric and the cloth-presser is in contact with the upper surface of said fabric; and Fig. 3 is a perspective view of the attachment detached from the needle-bar.

1 represents the needle-bar, 2 the needle, 3 the needle set screw, 4 the thread leader, 5 the thread leader screw, 6 the attachment bracket, 7 the cloth-presser standard provided with the presser-foot 8 and stop pin 9, 10 the cloth-presser spring, .and 11 the needle opening in the foot 8.

Referring more particularly to Fig. 3, the bracket6 is constructed of an integral piece of comparatively thin sheet steel, the circular portions 12 and 13 of which serve to clamp said bracket on the needle-bar, as shown in Figs. 1 and 2, the notch 14:, in connection with the needle set screw 3, acting to hold the attachment against vertical movement on the needle-bar and so that the successive stitch formations may be conveniently inspected.

The closed, central, vertical portion of the bracket 6 comprises a guide bearing 15 for the cloth-presser standard 7, said bearing be ing provided at .its upper end with a notch 16 which coacts with the pin 9 to prevent said standard from being withdrawn from said guide bearing. 17 represents a spring step formed on the standard 7 upon which the lower end of the spring 10 rests.

The construction of the bracket 6 forms an important element in effecting the stability of the device and provides convenient means for attaching it to and detaching it from the needle-bar; and the formation of the guide bearing as herein disclosed makes an extension of the curved portions 12 and 13 of the metal forming said bearing, enabling said curved portions to be expanded sufficiently to position the bracket upon the needle-bar without interfering with any of the parts carried by said bar or said bracket.

In removing the bracket 6 the operator first turns it in a direction to release the notch 14 from engagement with the needle set screw, and then moves the attachment vertically on the bar to a position above said set screw, which permits the removal of the bracket.

In the operation of the device, the down ward movement of the needle-bar, suflicient to cause the point of the needle to enter the fabric, carries the presser-foot down upon the fabric where it remains untilt-he needle again leaves the fabric, when the pin 9 arrests the spring-controlled movements of the standard 7, and the further upward movement of the needle-bar carries the presserfoot off from the fabric, leaving the latter free to be movedoby the operator.

I claim- In an embroidering attachment for sewing machines, a needle-carrying bar provided with a needle set-screw, a sheet metal bracket comprising yielding portions for attaching it to said needle-carrying bar, one of said portions being provided with a notch for engagement with said needle set-screw to hold said bracket against vertical movement on said needle-bar, a guide bearing formed integrally with said bracket, a standard In testimony ivher'e'o f, I have signed my mounted to move vertically in said bearing name to this specification, in the presence of and provided with a resser-foot, a stoptwo subscribing WitnessesQ pin located in the opposite end of said JOHN D. KARLE. standard, and a spring for resiliently holditnesses: ing said standard and presser-foot against ABBIE M. DONIHU,

vertical movement. THOMAS CAMPBELL.
