IMPROVEMENT IN LIOOMS FOR CIRCULAR WEAVING.

Specification forming part of Letters Patent No. 72,362, dated December 17, 1867.

To all whom it may concern:

Be it known that I, JOHN BUsER, of the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Loom-s for Weaving Cylindrical Articles; and I do hereby declare the following to be a full, clear, and exact description of the said inventionreference being had to the annexed drawing, making partof this specification, whereinf Figure l is a plan of the machine, with th guide-roller over which the cord passes removed. Fig. 2 is an elevation, the frame being removed at the line .r a'. Fig. 3 is a sectional plan at the line fr fc. Fig. 4 is a similar plan at the line y y and Fig. 5 is a sectional plan below the line y y', Fig. 2.

Similar marks of reference denote the same parts.

The object of my invention is to weave a covering for shade-cord, or toA weave any character of circular covering or cylindrical articles, and said invention consists in a series of warp-movers standing radially, in combination with a shuttle revolving around the article being formed. I also make use of a peculiar stop-motion that prevents a further movement of the parts when'either a warp-thread or the shuttle-thread breaks. l Y

In thedrawing, a a are the frames of the machine, of suitable size and character. b is a table, upon which the warp-spools c c are placed, and kept from turning too freely by .,a cord, l and spring 2, acting on the grooved pulleys of the spools, or in any other convenient manner. 3 3 are guide-wires, between which the threads from the warp-spools c pass to the friction-rollers d d, kept together by a spring, 24, and the friction regulates the tension of the warps. I cover one or both of the rollers d with felt or other elastic material, so as to give a better hold upon each of the warp-threads. The warps pass below the guide roller or drum d', and up through eyes at the ends of arms e e. These arms are hinged at their lower ends 4 to the bed-block al, and stand radially around a center shaft, j', running upward and outward. The threads, drawing in toward the weavingpoint 6, hold these larms c up; but in case of any warp being loose its arm moves sufficiently to take up the slack. If thread breaks, its arm @falls and strikes upon one of the levers g, projectin g from the shaft g or g2, giving the same a partial rotation. 7 is a lever on the shaft g?, acting upon a lever, 8, on the shaft g1, so as to communicate motion from one to the other. From the shaft g1 a link, 9, connects with a latch, l1., upon the clutch-lever h', so that when either of the shafts g1 or g2 is turned the latch h. is raised so as to be acted upon by a piu, 10, projecting down from the under side of the cam l, and press back the latch t', that holds up the clutch-lever h', and allow its spring ll to draw down the outer end of said lever, and lift the coupling or clutch k from connection with the pinion l1, and thereby stop the rotation of the machine if a thread breaks. The pinion Z1 isto be driven by the pinion l2 on the shaft 12,. or in any desired manner. The clutch-lever h has a projecting handle, by means of which it may be raised to connect the power, and held up by the latch i. The bed a2 is provided with forked bearings around its ed ges for the warp-movinglevers m m. Each of these is provided with a curved warp-mover, n, with an eye at its inner end. These levers m m are connected across by wires 13, so that motion only has to be given to one of the 1evers in each pair. The warp-threads pass from the eyeson e e through the eyes on n up to the point of weaving, 6, and the warp-movers n being changed each passage of the shuttle, the weaving is performed of the usual character, the shuttle or shuttles being driven around in a circular raceway in the bed o', as hereafter set forth, and, passing between the warps, de-

posit the weft-thread, and the bed o is slotted radially to allow for the play of the warps.

The levers m are moved at the proper time by the cams Z and Z4 acting upon rollers at the ends of arms p p, swinging upon fulcrum-studs 15, and connected by links 16 to the said levers m.

'I he shaft f extends up to the gear q, that drives the gears q1 and shafts 17, which have their journals in the beds a2 and 0.', and carry at their upper ends gears g3, (shown by dotted lines in Fig. 1,)whivch act upon teeth in the base of the shuttle-frame o, to propel the same around in its circular raceway in'o, the gears g3 all traveling in the same direction, and being placed so that one gear takes the teeth on the shuttle-base before the previous gear ceases to act on the same. Where a cord is covered, the said cord is supplied from a reel, r, with a spring-friction, and the same passes up through a tube, 1^', in the center of the bed 0 thence to the point of weaving, 6. The shuttle-frames taper toward the same point, and the wefttliread is led oif through a hole at the apex.

The bobbin s in the shuttle-frame o has a spring-friction, s', applied thereto, and the weft-thread leads behind the spring-bow axis 18 and in front of the spring-bow 19, so that when the weft-thread is in place the springbow 19 is inside the shuttleframe o; but if said thread runs out or breaks, a little spring coiled inside the frame o turns the bow 19 out, and in the revolution of the shuttle this bow 19 eomesinto contact with a lever, t, on a fulerum, 20, and the other end of the lever t presses a bar, t1, aside, so that it is no longer supported by a'notch in its side, taking the plate 21, and falls. The bar t1 has an arm, t2,

that, coming` into contact with one of the levers g, moves that and the shafts g1 and g2, and causes the disconnection of the clutch h and the stopping of the machine.

The material as it is woven is drawn away by the barrels u and e, acted upon by the worin-pinion e and wheel u', to the barrel a, and the material is coiled on a spool or reel, w, set in a swinging` frame, lw', and driven by a belt, 23. A spring, x, added to the weight of the spool w and frame, causes sufcient friction of the belt 23 to turn the spool w as the woven article is supplied to it.

This machine may be fitted to weave with any desired number of warps by multiplying the parts.

What I claim, and desire to secure by Letters Patent, is

1. A series of warp-movers acting radially and moved by the mechanism shown, in combination with a shuttle revolved between the warp-threads by the gearing, arranged and operating as set forth. p

2. The arms e, in combination with the shafts gl g2 and disengaging mechanism for stopping the machine it' a warp-thread breaks, substantially as set forth.

3. The bow 19, applied in the shuttles, in combination with the disen gaging mechanism, substantially as set forth.

In witness whereof I have hereunto set my signature this 6th day of May, A. D. 1867.

JOHN BUSER.
