QUILTING ATTACH M ENT FOR SEWING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 289,395, dated December 4, 1883. Application filed March 21,1883. (No model.) I

To all whom it may concern.-

Be it known that I, HENRY T. DAVIS, the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Quilting-Framesfor Sewing- Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to those quilting attachments for sewing-machines which are provided with a frame having suitable wheels running on atrack mounted on a suitable support, and extending at the side onto the machine-table.

My improvement consists in certain details of construction hereinafter described, and pointed out in the claims.

Figure 1 is a perspective view of the frame in use. Fig. 2 is an enlargedperspective view of an end portion of the frame. Figs. 3 and 4 are respectively a detail elevation and a section showing a supporting-wheel upon the rail. Fig. 5 is a detail perspective view of part of the track-rail and clamp connecting it to the sewing-machine table; and Fig. 6 is a side view of the clamp, with the table in section.

A is the table of a sewing-machine, and B the fixed arm carrying the needle-bar.

O is a straight rail, that is laid upon the table and secured thereto by clamps D, that engage beneaththe table and are tightened by screws E. The screwE is adjustable along the rail by means of series of holes 0 0", into any of which the screw may be inserted, so as to accommodate the clamp to tables of various widths.

As a modification, the clamp may be made adjustable upon the rail, when only one hole of the series 0 would berequired. ,The ends of the rail are supported upon hinged legs F, that may be folded up to the bottom of the rail when the frame is packed away. The rail has a track-strip, G, upon which run grooved wheels H, that are attached to the longitudinal central rail, I, of the frame upon which the quilt J is stretched.

K K are the end bars of the frame, said bars being fixed transversely to the ends of i the rail I.

L L are the rollers upon which the quilt is rolled. These rollers have journal-bearing in the bars K, one end, L, of each roller turning in a closed socket, and the other end,

Z, in an open socket, K, allowing the removal of the end of the roller transversely.

M M are ratchet-wheels upon the end of each roller, with pawls N N to engage the ratchet-wheels and tation of the rollers.

O is a stretcher-bar fitting at one end in I bracing-lips and bearing against the side of 70 bar K. The weights 1? are for the purpose of holding down the side of the frame which rests upon the table A, the weights being made removable from side to side for that purpose. I

The frame is shown made of wood; but I do not confine myself to this material, for the rolls and bars as well as the rod and rollers may be made of gas-pipe or-metal in other" for1n,0r of wood.

The operation is as follows The quilt is rolled upon the rollers L in the manner shown when it is desired to run lines of stitches parallel with the edges. WVhen stitching obliquely to the edges, the quilt is rolled upon 85 the rollers, accordingly the lines of stitches always being parallel to the rollers. After one-half the quilt (more or less) has been stitched, the quilt is rolled upon the rollers L in the opposite directions, changed accordingly, andtheframe is removed from the track-rail O and turned half around, so as to bring the other one of the rollers L beneath the arm B, and the quilting is completed from the other side.

I claim herein as new and of my invention- 1. An adjustable weight, I, in combina tion with a quilting attachment having guiderail and its supports, and adapted to be su-p- IOO ported at one side on the ble.
