SEWING-MACHINE ATTACHMENT.

Specification of Letters Patent.

Patented Jan. 27,1914.

Application filed June 4.1913. Serial No. 771.725.

To (ZZZ 1072 am it may concern Be it known that I, MINOR E. TYNES, a citizen of the United States, residing at Gloster. in the county of Amite and State of Mississippi, have invented a new and useful Sewing-Machine Attachment, of which the following is a specification.

The device forming the subject matter of this application is an attachment adapted to be applied to the needle bar of a sewing machine, to facilitate the operation of embroidering material upon the work table of the machine.

tlne oliiject of the present invention is to provide a device of this type which will str tch the material taut.

Another object of the invention is to provide novel means for operatively assembling the structure with the needle of a sewing machine and with the needle bar of the machine.

it within the scope of the invention to improve generally and to enhance the utility of. devices of that type to which the present invention appertains.

\Yith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing :Figure 1 shows one form of the invention in perspective, applied to the needle bar of a sewing machine: Fig. "2 is a side elevation of the attaclmient shown in Fig. 1: Fig. 3 is a top plan of the attachment shown in Fig. '3: Fig. lis a perspective showing a slight modification in the invention.

The embroidery attachment constituting the subject matter of this application is fashioned from a single strip of material. one end of which. indicated at 1, is up turned, to prevent the said end from catching in the material. The free end of the strip is bent upon itself to form a lOUP-i beshaped primary head 2. This head 2, ing resilient. serves to stretch the material laterally. and to hold the same taut. One end of the primary head 2 is bent upon itself as indicated at 3, to form a loopshaped secondary head l which extends within the contour of the prin'iary head 2. "he secondary head 4 serves to hold the material down while the same is being stretched by the primary head 2, and the stretching operation, to a greater or less extent, is enhanced by the action of the head l, this head, like the head 2, being resilient. One side of the secondary head 4, indicated at 5, is prolonged to form an extension (3 which projects toward the operator. The extension 6 gives resiliency to the structure and permits the heads 2 and l to engage properly with the material. The end of the extension (3 is formed into a helical spring 7. The spring T adds to the resiliency of the structure and serves to aid the extension (3 in causing the heads and 4: to en gage upon the material which is being embroider d. One convolution of the helical spring 7 extended to form an upwardly inclined arm 8. The rear extremity of the arm 8 is bent upon itself to form a helix which constitutes an eye 9 adapted to receive the needle 10 of the sewing machine. The upper terminal convolution of the helix or eye 9 is prolonged laterally as indicated at ll, and the laterally extended portion 11 terminates in a helical spring 12. The terminal convolution of the spring 12 is extended to form a curved finger let, the free end of which is adapted to receive the lug 15 of the needle bar 1.6 of the machine, in which. ordinarily, the needle holding set screw 17 is located. The curved finger let is offset. as indicated at 18, so as to engage over the lug 15. The spring 12 adds to the resiliency of the finger l-l and serves to maintain the same engaged with the lug 15.

In Fig. t, wherein a modified form of the invention has been shown, the parts above described are referred to by the reference characters previously employed. the sufiix (1 being added in Fig. i. In Fig. 4. the heads 2 and, 4e are of bluntly pointed form, whereas in Fig. 3, the corresponding elements are of approximately rectangular outline. The laterally extended portion 11 in l -l projects in an opposite direction to the corresponding portion ll of Fig. 3, and as a consequence, when the attachment shown in Fig. is assembled with a needle bar of a sewing machine. the heads 2 and 4;, instead of projecting away from the operator as shown in Fig. .1, project toward the operator.

The structures hereinbefore described are so constructed that the threading operation is not interfered with. The work is at all times fully visible, and, as hereinbefore set forth, the heads 2 and 2 effect a lateral stretching of the material, so that the same is at all times taut. In addition to the fore going advantages, it is to be observed that the inclined arm 8 in Figs. 1, 2 and 3, serves to prevent the finger of the operator from being thrust beneath, the needle 10.

Having thus described the invention, What is claimed is An embroidery attachment for a sewing machine, fashioned from a single strip of metal, one end of which is free and is bent upon itself to form a loop shaped primary head, one end of the primary head being bent to form a secondary loop shaped head,

the secondary head extending within the contour of the primary head, one side of the secondary head being fashioned into an upwardly extended arm, the arm supporting needle receiving means and being provided with means for engaging the needle bar of a sewing machine, the secondary head cooperating with the primary head to increase the bearing area and serving also to position the arm in approximate alinement with the longitudinal center of the primary head.

In testimony that I claim the foregoing as my own, I have hereto afiiXed my signature in the presence of two witnesses,

MINOR EUGENE TYNES. lVitnesses:

JAMES G. ANDERs, J. L. ROGILLIO.
