SEWING-"MACHINE ATTACHMENT.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed July 25, 1905. Serial No. 271,138.

To all whom, it 71 1/04 concern.-

Be it known that I, PEYTON RoBB, a citizen of the United States, residing at Walcott, in the county of Greene and State of Arkansas, have invented new and useful Improvements in Sewing-Machine Attachments, of which the following is a specification.

My invention has relation to new and useful improvements in sewing-machine attachments which are used in conjunction with the head of a sewing-machine and quilting-frame.

The object of my invention is the production of a device of this class that may be conveniently and readily attached to the head of a sewing-machine and a quilting-frame and with the assistance of said head and frame stitch a quilt or other covering in an eflicient and expedient manner.

WVith these ends in view my invention consists in the novel construction, combination, and arrangement of parts, as is hereinafter set out in the specification and claims hereuntoattached.

In the accompanying drawings, in which like parts are designated by like characters throughout the several views, Figure 1 is'a perspective view of my invention as applied. Fig. 2 is alongitudinal vertical sectional View of my invention out on the line X X of Fig. 3, the dotted lines representing a band which passes around the crank and pinion wheels of my invention and the band-wheels of the head of a sewing-machine. Fig. 3 is a top plan view of my invention. Fig. 4: is a front end View of my invention.

My invention is described as follows:

The numeral 1 represents trestle or other benches to support my invention. I

2 represents the frame of my invention, said frame consisting of two opposite longitudinal beams 3 and cross-beams 1. Secured to said cross-beams 4 midway between said longitudinal beams 3 is a longitudinal beam 5, provided with a longitudinal groove in which is secured a rack-bar 6. Slidably mounted on said longitudinal beams 3 are two oppositelydisposed beams 7 and 7 secured together by means of cross-beams 8. The lower ends of said beams 7 and 7 are constructed in such a manner as to provide outer flat portions and downwardly-extending flanges 9. When in position, the said beams 7 and 7 are slidably mounted on said longitudinal beams 3 of said frame, so that the outer fiat portions thereof rest on the upper faces of said beams, which beams constitute the track, the said downwardly-extending flanges 9 coming in contact with the inner faces of said beams 3, and thereby preventing any lateral movement of said beams 7 and 7. -Secured to and extending downwardly from said cross-beams 8 is a beam 10, provided with two perforations 11 and 11'. Journaled in the said perforation 11 of said beam 10 is one end of an axle 12, the opposite end of which axle is journaled in a perforation in said beam 7 and is rigidly secured to the central part of a crank-wheel 13, provided with a crank-handle 13. Bigidly secured to a pinion 1 1, located near the rear portion of said beam 7, is an axle 15, said axle being journaled in a perforation in said beam 7 and the perforation 11 of said beam 10, said axle having extending eccentrically from its inner end a pivot 16. Pivoted to said pivot 16 at its upper end and extending downwardly therefrom is a push-lever 17 the extreme lower end of which terminates in a chisel-shaped portion 17 which engages the said rack-bar 6 when my invention is in operation.

The operation of my invention is as follows: Iset the frame of my invention on said benches 1 and mount the said beams 7 and 7 on said longitudinal beams 3, as described. I then place the head 18 of a sewing-machine on said cross-beams 8, place one side of a quiltingframe 19 under the arm 20 of said head 18 and pass said band 18 around the crank and pinion Wheels 13 and 14, respectively, of my invention andthe band-wheel 18 of said sewingmachine head 18. I then turn the crank-wheel 13 by means of the crank-handle 13, also causing said pinion-wheel and band'wheel to rotate, said pinion-wheel14 by means of the said axle 15 and eccentric-pivot 16 causing said push-lever to engage the teeth of said rackbar 6 and propel said beams 7 and 7 along said longitudinal beams 3 of said frame 1 and carry with them said sewing-machine head, which stitches the quilt or other covering. It will be obvious that the seams may be stitched any desired distance apart by setting the quartergage of the sewing-machine head. After stitching one line I move my invention toward the quilt or other covering until the quartergage comes directly over the seam and raise the push-lever 17 and slide the two oppositelydisposed beams 7 and 7 back to the opposite end of the frame and proceed as before. When the quilt or other covering is stitched as far as the arm of the machine-head will allow, the quilt is rolled on the near side beams IIO of the quilting-frame, and when desired the other side of the quilt may be put under the arm of the sewing-machine head.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A sewing-machine attachment, consisting of a frame 2, consisting of two opposite longitudinal beams 3 and cross-beams 1; a longitudinal beam 5, provided with a longitudinal groove, secured to said cross-beams 1, midway between said longitudinal beams 3; a rack-bar 6, secured in'the said longitudinal groove of said longitudinal beam 5; two oppositely-disposed beams 7 and 7, secured together by cross-beams S, said beams provided with two perforations 11 and 11; an axle 12, journaled at its inner end in said perforation 11, of said beam 10, its opposite end journaled in a perforation in said beam 7 a crank-wheel 13, provided with a crank-handle 13, said wheel being rigidly secured at its central part to the last-mentioned end of said axlel2; an axle 15, journaled at its inner end in the perforation 11', of said beam 10, its opposite end journaled in a perforation in said beam 7; a pinion 14, secured at its central part to the said axle 15; a pivot 16, extending eccentrically from the inner end of said axle, and a pushlever17, pivoted to said pivot 16 at its upper end, the extreme lower end of said lever terminatingin a chisel-shaped portion 17, which engages in said rack-bar 6, substantially as shown and described and for the purposes set forth.
