QUILTING-FRAME FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 396,328, dated January 15, 1889.

Application filed September 26, 1887- Serial No. 250,737. (No model.)

To all whom it 71mg concern..-

Be itknown that I, HENRY T. DAVIS, of the city, county, and State of New York, have invented certain a new and useful Improvement in Sewing-\Iachine Quilting Attachments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which Figure I is a perspective view of the improvement, showing the same attached to a sewing-machine. Figs. II and III are perspective views of the end bars of the frame. Fig. IV is a detail perspective view showing the opposite ends of the central cloth-roller. Figs. V and VI are views, partly in section, showing winding-rolls in different positions. Fig. VII is a detail perspective view showing the opposite ends of the winding-roller. Figs. VIII and IX are detail longitudinal sections showing the locking ends of the lining-roller in its different positions. Fig. X is a side view of the inserted ferrule. Fig. XI is a detail longitudinal section of one end of a winding-roller. Fig. XII is a detail perspective view showing the rail-joint and inelin ed jointbar. Fig. XIII is a detail side view of the rail-joint with the sewing-machine table in vertical section. Fig. XIV is a detail perspective view showing the tcnter-h ook. Fig. XV is a detail perspective view of a part of one of the strips of cloth by which the quilt is connected to the winding-rollers. Fig. XVI is a perspective viewof one of the gudgeon-sockets, and Fig. XVII is a similar view of another of the gudgeon-sockets of the winding-rollers. Fig. XVIII is a perspective view of the legbracket. Fig. XIX is a detail view of the top of one of the legs.

A part of a sewing-machine table is shown at 1, and the head of a sewing-machine at 2.

The sewing-machine forms no part of my invention, although the invention is to be used with a sewing-machine.

3 4 is a rail composed of two parts (3 and 4) in line with each other, and connected together by means of an inclined bearing-bar, 5, which is constructed to rest on the top of the sewinganachine table 1. The part 3 of the rail is secured to the bearing-bar by screws 6, or by other means, and by means of the clamping-bolt 7. The end of the part4 of the rail is connected to the bearing-bar by a screw-bolt, 8, and by the clamping-bolt 7 at that end of the bar 5.

9 are clamps which engage beneath the edge of the table 1, and which are pressed against the same by the bolts 7, so as to hold the bar and rail 3 4 firmly in position upon the table.

One or both ends of the rail 3 4 are provided with additional support by means of legs 10, which have at the upper ends screweyes or equivalent means of attachment to a bracket, 11, which is made fast to the rail. The means of connection I show between the rail and the legs consists of slots in the bracket, through. which are passed the ring of the screw-eye 12, and after this is done the screw-eye is turned one-fourth around, so that the ring is transverse to the slot and so bears against the top of the bracket, while the upper end of the leg 10 bears against the bottom of the bracket. The bracket is so formed that the legs cross each other, and their ends are so separated as to form a broad base of support. (See Fig. I.)

13 is the central fixed rail of the frame, which is firmly fixed at its ends in the end bars, 14 and 15, of the frame.

The means of attachment which I show 0011- sists of mortise 16, cast in each end bar and filled by a tenon at each end of the rail 13.

The end bar, 14, has three slots, 17, 18, and 19, open at the top and forming bearings for the gudgeons and 21 at the ends of the

rollers

22, 23, and 24, upon which the material is coiled. These gudgeons turn freely in the

bearings

17, 18, and 19, while at the other ends the rollers carry means for locking them, so as to prevent their rotation, and thus the material between the rollers is kept sufficiently tight. The locking end of the roller 22 has a square or otherwise non-eircular gudgeon or pin, 25, which fits a notch, 26, of the same shape when this end of the roller is in its normal (or lower) position, so that the roller cannot turn. The notch 26 has at top an enlargement, 27 in which the pin turns freely. Thus when this end of the roller is raised it can be turned to unwind the cloth from it or to wind up the cloth upon it.

The roller is shown square in its body; but I do not confine myself to this shape. It has a number of headed or plain pins, 28, to which is attached a strip of cloth, 2?),having buttonholes or eyes 30, to engage on the pins 28. This cloth is for the attachment of the edge of the quilt-lining 31, which is made fast to the opposite edge of the cloth strip to the eyes 30 by means of a row of stitches. After the lining has been made fast to the strip 29 and the strip has been made fast to the roller, the lining is coiled upon the roller, leaving uncoiled only enough to reach the next roller, 23. Another piece of cloth, 29, is made fast to the opposite edge of the lining-sheet, and at the same time one edge of the covering-cloth 32 is made fast to the latter strip 29. This latter strip should be wide enough (say eight inches) to reach the roller when the strip is made fast to the pins 28 upon the roller 24. The opposite edge of the cloth 32 is attached to another cloth strip, 29, made to engage on the pins or buttons 28 of the central roller, lVhen placing the work upon the frame, the lining is coiled on the roller 22, as aforesaid, and the covering-cloth 32 is coiled upon the roller 23. The open edges of the lining and coveringcloth are now at the central roller, 23, and fast to the cloth strip 29, which is fast to the roller 24. The frame being put in position, if not in place already, with its bearing-wheel 33 resting in the groove 3% of the rail 3 4, a line, 35, of cotton bats is laid on the lining, and, by unlocking the rollers and winding a part of the cloth strip 29 on the roller 24, the edges of the lining 31 and covering-cloth 32 are carried to the needle of the sewing-machine. The rollers are then locked in position, and one corner of the quilt being brought beneath the needle, a row of stitches is run across the quilt. Then the rollers are again unlocked, and the quilt being moved the distance for the next row of stitches, and the frame drawn back, another row of stitches is made after the rollers have been again locked in position.

The manner of locking the roller 22 in position has been already described. I will now describe the device for locking the

rollers

23 and 24 in position, the means being similar in the two instances.

The gudgeon 35 of each of these rollers enters a bearing-socket, 36, in the end bar, 15, said socket being surrounded by a circle of pin-holes, 37, into any one of which may be made to enter a pin, 38, which is placed a little distance from the gudgeon and parallel with it. This device is shown very clearly in Figs. II, IV, V, and VI. In Fig. II is shown the series of holes 37, in Fig. IV the pin 38, in Fig. V the pin is shown engaged in one of the holes, and in Fig. VI the pin is shown disengaged, so that the roller may be turned. The rollers 23 and 24: are made so as to have sufiieient end-play to allow the engagement or disengagement of the pin 38. p

In order to prevent the splitting of the ends of the rollers in which the gudgeons 20 and 21 are placed, I force into these ends of the rollers ferrules 39, whose outer edges, 40, are preferably flanged over, so as to strengthen them at this part and to assist, by the entrance of the flange into the wood, in. holding the ferrules in place. (See Figs. VI, VII, IX, and X.)

The inclination of the inclined bearing-bar 5 is such as to increase the ease with which the frame passes beneath the needle when making the row of stitches. It will be seen that the part 4 of the bar may be removed from the part 3 and the block 5 by the loosening of only two bolts, and then the parts may be folded together.

41 is a tenter-hook, which is supported 011 a rod, i2, extending from one to the other of the gudgeons 21. The hooked end 42 engages in the material of the quilt, as seen in Fig. I, to prevent it being drawn endwise on the frame under the action of the feed mechanism.

It will be seen that the eye of the hook will slide freely on the rod 42 as the quilt is rolled up on the roller 24:, and thus will present no impediment to this operation.

I claim as my invention The combination, with the bearing-rail composed of sections 3 4, of the wedge-shaped bearing-bar, the bolt 8, passing through one section of said rail and the bar, the screws 6, passing through the bar and into the other section of rail, clamps 9, secured to the ends of said bar, and the bolts 7, passing through the bar and rail and said clamps, as set forth.

HENRY T. DAVIS.
