LENG-SELVA GE MOTION.

SPECIFICATION forming part of Letters Patent N o. 691,204., dated January 14, A1902.

Application ilerl August 20, 190I To all 'whom t zit/ty concern;

Be it known that I, HORACE H. SUTCLIFFE, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Leno-Selvage Motions, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an attachment for looms upon which more than one width of cloth is woven at the same time.

The object of the invention is to produce leno-selvages. l

My invention relates to that class oi' such attachments in which the threads to form this selvage are passed through the eyes of the carries the frame for said needles the warpthreads upon the outside of the inner edges of the two pieces of cloth that are woven together pass. The needles are connected to a frame which is so supported as by appropriate connections to be given a lateral movement in either direction, so as to lie on one or the other side of said warp-threads, and a vertical movement to form a stitch with said warp-threads, the needles being moved alternately on each side of said warp-threads.

My invention consists in certain improvements which make the operation of said devices more certain and prevent the disarrangement of the mechanism and enable the device to be of simple and cheap construction, all of which will be apparent from the embodiment of my invention illustrated in the drawings and hereinafter described.

In the drawings, Figure l is a perspective view of the device in operation. Fig. 2 is a side elevation of the device. Fig. 3 is a section on line 3 3 of Fig. 2. Fig. 4 is a plan view of the finished fabric. Fig. 5 is a partial side elevation of Fig. l. Fig. 6 is a perspective view of a modified form of embodiment of my invention. Fig. 7 is a section on line 7 7, Fig. 6.

A is a frame having the upper end a and the oriced lower end b. Between these two ends extend the bars c, having grooves at o' on their inner surfaces, and the central rod or bar d, out of alineinent with the bars c.

. Serial No. 72.656. (No model.)

B B are needles, having the eyes Z22 b2 and the curved or bent tails b' ZJ. The needles are secured together, at a portion thereof between the eyes and th e tails of the needles, by the plate l). The width of the plate D is less than that of 'the orifice iu the end b of the frame A, so that said plate D, with. the needles B B', may readily slide vertically in said orificed end band move laterally slightly in either direction. The curved tails Z9' b project beyond the end of frame A, so that they are prevented from entering the oriiice. The needles above the plate are guided in their vertical and lateral movements by the groove c' on the inner surface of the bars c. The frame A is secured at the upper end to a fixed part F of the loom, as shown in Figs. l and 5. The tails b b' of the needles B B have the oriiices e, from which cords E E lead to the jacquard or shafts of the loom. The threads F to form the selvagge-stitches are passed through the eyes b2 b2 of the needles B B'. The warp-threads H upon the outside of the inner edge of the two pieces of cloth that are woven together pass between the bars c. The cords F. E' are lifted alternately; but the alternation may be after each pick of the loom or after two or more picks. The lifting of the cordE will lift the needles B -B and move the needles to the left, as shown in Fig. 2, while the movement of cord E will lift the needles and move the needles to the right. In the construction speciiically illustrated I have shown the cords E and E operated alternately at each pick, and the resultant weave formed is that shown in Fig. 4.

i The cord E or E is moved so as to tilt the needles B B', and then as t-he shed is formed the needles are lifted with the upper warpthreads Hand to one side orthe other of said threads. After the shuttle has passed through the shed and the pick has been formed the tension upon the cord E or E is released and by gravity the needles will descend to the original position. On the next lift of the needles the opposite cord to that oi' the previous lift will be operated upon, resulting iu bringing the needles to the side of the warp H opposite to that of the previous lift, this resulting in the weave of Fig. 4.

In Figs.v6 and 7 I have shown a slightlymodified form of embodiment of my inven- IOO tion, in which the frame A is formed with a groove or oriice b4 from top to bottom and provided With slots M, through which the Warp-threads H pass. In this construction the free ends of the needles are guided in their vertical and lateral movement by the walls of the upper portion of frame A.

With my improved construction the device is of extreme simplicity. The needles are protected and guided in all their movements, and the device is thereby enabled to operate with certainty.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-

l. The combination, with a grooved frame, of needles,a plate connecting said needles and of width less than the width of said groove, said plate `being adapted to move vertically and laterally in said grooved frame.

2. The combination,with a grooved frameL of needles, a plate connecting said needles and of width less than the Width of said groove, said plate being adapted to move vertically and laterally in the grooved frame and guides adapted to directly limit and guide the free ends of said needles in their lateral and vertical movement.

8. The combination, with a grooved frame, of needles, aplate connecting said needles and of Width less than the Width of said groove, said plate being adapted to move vertically and laterally in the grooved frame andl guides adapted to directly limit and guide the free ends of said needles in their lateral and vertical movement, the inner faces of said guides being rounded.

4. The combination, with agrooved frame, of needles, aplate connecting said needles and of Width less than the width ot' said groove, said plate being adapted to move vertically and laterally in the grooved frame, the tails of said needles being bent beyond the lower part of the said frame.

5. The combination, With a grooved frame, of needles, a plate connecting said needles and of Width less than the width of said groove, said plate being adapted to move vertically and laterally in the grooved frame and guides adapted to limit and guide thefree ends of said needles in theirlateral and vertical movement, the tails of said needles being bent beyond the lower part of the said frame.

6. The combination, With a grooved frame, of needles, a plate connecting said needles and of width less than the width of said groove, said plate being adapted to move vertically and laterally in the grooved frame and guides A adapted to limit and guide the free ends of said needles in their lateral and vertical movement, the inner faces of said guides being` rounded, the tails of said needles being bent beyond the lower part of the said frame.

7. In a device of the character described, in combination with the needles connected together at one end, and means to move said needles vertically and laterally, of guides in line of movement of the vertical and lateral movement of and coacting with the free ends of the needles.

8. In a device ofthe character described, in combination with the needles, connected together at one end, and means to move said needles vertically and laterally, of guides in line of movement of the vertical and lateral movement of the free ends of said needles, the surface of said guides coacting with said needles being rounded.

9. In a device of the character described in combination with a tubular frame, of needles movable vertically and laterally in said tubillar frame,the wall limiting the lateral movement of said needles and guiding the needles in their vertical movement.

In testimony of which invention I have hereunto' set my hand, at Philadelphia, on this 7th day of August, 1901.
