QUILTING-FRAME FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 334,646, dated January 19, 1886.

Application filed January 27, 1885. Serial No. 154,126.

To all whom it may concern.-

Be it known that I, HENRY T. DAVIS, a citizen of the United States, residing at New York,

in the county and State of New York, haveinvented certain new and useful Improvements in QuiltingFrames for Sewing-Machines, of which the following is a specification.

My invention relates to means for winding the different parts or pieces of the quilt (before they are united and stitched together) on separate contiguous bars or rollers, and has for its object the independent regulation of the feed of the cover and the lining of the quilt by the pressure of one coil of material upon the other coil, as will be hereinafter described.

My'invention consists in certain details of construction, hereinafter specifically referred to, and pointed out in the claims.

Referring to the accompanying drawings, which form apart of this specification,Figure 1 represents a perspective view of my quiltingframe embodying my new improvements. Fig. 2 represents an end elevation of one of the end bars of the frame. Fig. 3 is a similar view of the opposite end bar.

A represents the ordinary roller or feedingbar which I have shown in former applications and patents of the United States, and which I have employed to wind the cover, the lining, and the intermediate bats before the stitching operation. In this instance the construction and arrangement are substantially the same; but I use this roller only for winding the lining and supplement it with a second roller, B, which I arrange in the same vertical plane as A, as shown in Fig. 1, and on this second or supplemental bar I wind the cover of the quilt to be sewed. These rollers are journaled in lugs I and B arranged, respectively, on the end pieces, J and 0. They are provided with cog-wheels A and B, which gear with each other or intermesh for the purpose of equalizing the feed of the cover andthe lining. A locking-pawl,b, is arranged upon the end piece, 0, and by locking one of the cog-wheels will stop the rotation of both rollers. The lug Iis constructed as shown in Fig. 3, and the rollers are adapted to be set into the bearings provided therein, and to drop into the open-end lug, B as shown in Fig. 2. I provide a tension-bar, D, having bearing in the vertical slots of the lugs D and H of the end pieces, 0

(No model.)

and J respectively. This bar is vertically adjustable in these slots, and is provided with a screw, d, by which it is adapted to be set in any desired position, according to the thickness of the quilt being made.

Upon the inner ends of the pieces 0 and J, I construct the segmental lugs E and G, and from one to the other extend the final winding-bar for the completed quilt. This bar is shown at E, Fig. 1. It is also desirable to make this bar vertically adjustable, and consequently I provide bearings at different heights on the lugs, as aforesaid. In these different bearings the winding-bar is adapted to findseats. One end of the bar is adapted to be set in the openings of the lug Gr, while the other will drop into the corresponding opening of the lug E. A ratchet-wheel, F, is arranged upon the end of the winding-bar, and a pawl,f, holds it in check or locks it when desired. The cog-wheels A B and the ratchet-wheel F are provided with ears or thumbpieces for turning the rollers or bars when desired.

The operation of the machine is as follows: The lining of the quilt to be manufactured is first wound upon the roller A and the cover to the same on roller 13. The latter roller may then be temporarily removed from its bearings and laid over upon the machine-table. The batting or filling is then laid upon the lining aforesaid, when the roller B is replaced, and the stitching may commence. XVhcnever it is desired to place in more batting, the latter part of the above operation may be repeated. The tension-bar D may be adjusted, if desired, and the Winding-bar E raised as the amount of goods accumulates upon it.

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

1. In a quilting-frame for sewing-machines, the combination of the end pieces, the main winding-bar journaled within the same, and the supplemental winding-bar arranged directly above, contiguous to, and in the same vertical plane as the main winding-bar, substantially as shown, and for the purposes set forth.

2. Ina quilting-frame for sewing-machines, the combination of the end winding and unwinding rollers and the end pieces of the frame with the tension-bar arranged above the quilt, the lugs upon the frame provided with the vertical slots, and means, substantially as described, for locking the tension-bar at any desired height relatively to the bed-plate of the machine.

3. In aquilting-fraine for sewingunachines, the combination of the end pieces provided with the upwardly-extending lugs adapted for the reception of the tension-bar and feed-rollers with said bar and rollers, as set forth.

4. In a quilting-frame for sewinganachines, the combination of the bed-plate of the sewingmachine, the end pieces, the adjust-able winding-bar adapted forthe reception of the goods when sewed, means for adjusting the windingbar, and the feed-rollers, substantially as set forth.

the purposes set forth, with the feed-rollers, the tension-bar, and the final winding-bar, as

' described.
