T. DAVIS, QUILTING FRAME FOR SEWING MACHINES.

Patented June 2, 1891.

UNITED STATES PATENT OFFICE.

HENRY T. DAVIS, OF NEIV YORK, N. Y.

QUILTING-FRAME FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 453,179, dated June 2, 1891.

Application filed August 12, 1890. Serial No. 361,806. (No model.)

- panying drawings, forming partof this specification.

My present invention relates to certain improvements on the attachment shown and described in Letters Patent No. 396,328, issued to me January 15, 1889.

My present invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a perspective View illustrative of my invention. Fig. II is an enlarged perspective view of one of the end pieces of the frame. Fig. III is a detail perspective view showing one end of one of the side rollers. Fig. IV is a detail side view of same, the end piece being shown in section. Fig. V is an enlarged perspective view of the opposite end piece to that shown in Fig. II. Fig. VI is an end view of the supporting-rail. Fig. VII is a detail perspective view of same.

Referring to the drawings, 1 represents part of the table and arm of a sewing-machine.

2 represents a rail, upon which the quiltsupporting frame is placed and moves. The frame consists of end pieces 3 4, side rollers 5, and a central roller 6. The face-cloth of the quilt is wound upon the roller 6, the lining on one of the rollers 5, and the two when stitched together upon the other roller 5, as in my patent referred to. The rollers are journaled in the end pieces 3 4, which are tied together by a strip 9, which travels on the rail 2. The end piece iis practically the same as the corresponding end piece of my patent mentioned, except the journal-openings are closed instead of open. The end piece 3 differs from the corresponding end piece of said patent in that it has ratchetteeth 10 formed around the journal-openings of the rollers, as shown in Fig. II. The rollers are connected to the end piece 4, as

in said patent; but they are connected to the.

end piece 3 by journal-screws 11,which pass through the openings 12 and enter the ends of the rollers, as shown in Figs. III and IV.

13 represents spring plates or strips of metal secured to the rollers, and which are bent'down across the ends of the rollers and inwardly at their lower ends, as shown at Figs. III and IV. The screws 11 pass through these plates to strengthen and guide them. The normal position of the plates is that shown clearly in Fig. IV, in which position they engage the teeth 10 and hold the rollers from turning backward. The ends lat of the plates are provided with perforations 15, adapted to engage pins 16, projecting from the rollers, so that when it is desired to hold the plates out of engagement with the teeth 10 it is only necessary to spring their free ends inwardly until the perforations are en'- gaged by the pins 16, and the plates will be held out of engagement with the teeth until they are forced out of engagement with the pins 16, thus adding materially to the convenience with which the frame can be used.

17 represents the supporting-legs of the rail 2. Instead of connecting these to the rail by the use of blocks 11,as in my said patent, I employ screw-eyes 18, made fast to the rail, and which enter the screw-eyes 20 in the upper ends of the legs. This forms a convenient and cheap manner of connecting the legs to the rail and dispenses with the use of the blocks referred to.

I claim as my invention- 1. In a quilting attachment, the combination of the rollers having pins projecting therefrom and end pieces in which the rollers are journaled, one of said ends having ratchet-teeth, and said rollers having springplates for engaging said ratchet-teeth and perforated at their free ends to fit over pins in the rollers, substantially as and for the purpose set forth.

2. In a quilting attachment, in combination with the rollers and end pieces, in which the rollers are journaled, one of said end pieces having ratchet-teeth, the spring-plates secured to said rollers and bent across the ends of the rollers and inwardly at the free ends, and journal-screws fitting in the ends of the rollers and passing through said plates, substantially as set forth.
