JAMES E. GILLESPIE, OF WARWVIOK, NEW YORK, ASSIGNOR TO THE FABRIC FIRE HOSE COMPANY, OF SAME PLACE.

CIRCULAR LOOM.

SPECIFICATION forming part of Letters Patent No. 361,758, dated April 26, 1887.

Application filed August 12, less. Serial No. 69,199. (No model.)

New York, have invented a new and useful Improvement in Circular Looms, of which the following is a specification.

My invention relates more particularly to looms for weaving multiple-fabric hose composed of two plies, the wefts of which run in opposite spiral directions through the warps, such hose being the subject of my Letters Pat ent No. 268,366, dated November 28, 1882; but certain features of the invention may be embodied in looms for weaving two-ply circular fabrics of other kinds.

The invention consists in certain combinations of circularshuttle-raceways, shuttles running thereon, and mechanism for driving said shuttles, and in certain combinations of shut: tles, shuttle driving mechanism, raceways, warp-shedding mechanism, and warp guiderings, all substantially as hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a vertical section of a loom embodying my invention adapted for weaving the two-ply fabric hose,which is the subject of the Letters Patent hereinabove referred to.

Fig.2 represents ahorizontal section on the dotted line as :r, Fig. 1, certain parts being removed. Fig. 3 represents a detail View, looking from the center of the loom outward, of a pair of shuttles,with their raceways and driv- 1ng mechanism; and Fig. 4 represents an elevation of part of the mechanism for operating the heddles. Fig. 5 is a plan view of part of the shuttle mechanism corresponding with Fig. 1, adapted for driving the upper shuttles I will first proceed to describe the shuttles and their raceways and driving mechanism.

B designates the upper shuttles and B the lower shuttles. One upper and one lower shuttle constitute a pair, and the loom may be provided with a single pair of shuttles; but for rapid work I prefer to employ two pairs of shuttles, as here shown. The two upper shuttles constitute what I term a set of shuttles, and the two lower shuttles another set; but each set,iustead of two shuttles, might com prise three or more shuttles, if desired.

As here shown, each shuttle B B is made in the form of a triangular frame, in which is journaled the weft-bobbin B; but the shuttles may be of any other suitable form.

The shuttleraceways are here represented as formed by three tiers or series of grooved rollers, there being an upper series, O, a middle series, 0, and a lower series, 0 all of which are adapted to turn freely on. journals or studs fixed in the upright bars or slats A, and the shuttles each have grooves a, which engage with the innermost flanges of the said grooved rollers, as best shown in Fig. 1.

The upper set of shuttles, B, are arranged between and in engagement with the tiers or sets of guide-rollers O G, and the lower shuttles, B, are arranged between and in engage ment with the two tiers or sets of guide-rollers 0 G The shuttles are therefore supported both at the top and bottom, and hence their inner ends are kept in the same horizontal plane, as the shuttles move and cannot drop down. D designates a piece of hose in the process of weaving, and E designates a central tube or hollow post, through which the completed hose may be delivered. ,The takeup might, however, be upward instead of downward.

F designates a tubular shaft surrounding the tube or post E, and having at its lower end a bevel-wheel, F.

G designates a horizontal counter drivingshaft provided with fast and loose pulleys, G G, over which a driving-belt may be passed, and also carrying a bevel-wheel, G which engages with the wheel F, and through it r0- tates the tubular shaft F. The counter-shaft G also carries a bevel-wheel, G, at its outer IOO end, which engages with a bevel-pinion, H, I

and through said pinion operates a vertical shaft, H, on which the pinion H is secured, as best shown in Fig. 2.

At the upper end of the tubular shaft F is a cross-bar or plate, I, which is rotated with the shaft, and the form of which is shown in Fig. 2. ,Upon each end of the plate or bar I, at its upper side, is pivoted a small roller, 1), which fits between two corresponding rollers, c, pivoted to each of the lower shuttles, B, as seen in Fig. 3. The rollers 0 on each shuttle rest upon and straddle the roller 2) on the plate or bar I, and as the said plate or bar turns or rotates in a horizontal plane the lower shuttles are carried with it. I

The rollers b 0, arranged as shown, for imparting motion to the shuttles from the rotary plate or bar I, are desirable, because they provide for giving a positive motion to the shuttles, and the warp-threads will pass between the rollers, or the rollers will pass over the warp-threads as the shuttles are moved.

The upper shuttles, B, are each provided with a pair of rollers, c, in their upper sides, and above the upper tier of guide-rollers (3 is a horizontal toothed ring, J, which has a circumferential'rib fitting in a groove, (Z, in the upper plate or ring, A, as shown. By this rib and groove the ring J is supported and maintained in a horizontal plane and allowed to rotate freely.

Depending from the ring J are hangers or brackets e, which carry rollers b, which fit be tween the rollers c on the upper shuttles, and when the ring is rotated it carries the upper set of shuttles, B, with it in the same manner that the plate or bar I carries the lower shuttles, B.

Above the ring J, in a fixed hearing, A*, provided in the plate A, there is arranged a horizontal shaft, K, which receives a rotary motion from the vertical shaft H, through bevel-wlfeels ff, and which has at its inner end a bevel-piniomf which engages with and drives the toothed ring J, as shown in Figs.

1, 5, and 6.

It may be understood that both the upper and lower shuttles derive their circular motion around their respective raceways from the one shaft G, and that the upper shuttles may move either in the opposite direction to or in the same direction as the lower ones, according to the gearing of the shaft H. If the bevel-wheel f engages with that, f, on that side of the shaft Hnearest to the ring J, as shown in Figs. 1 and 5, the upper shuttles will move in the opposite direction to the lower ones; but if the bevel -wheel f engages with that, f, on the side of the shaft H farthest from the ring J, the direction of the motion of the upper shuttles and the lower ones will be projecting from the shaft in opposite directions. There are four shafts N, one for oper-. ating each group of heddles.

Surrounding the loom are three stationary guide-rings, O O 0 for the warps. The upper ring, 0, guides the warps which are interwoven with the wefts carried by the upper shuttles, B, to form the inner ply of the hose, and the lower ring, 0, guides the warps which are interwoven with the wefts carried by the lower shuttles, B, to form the outer ply of the hose. The middle or intermediate ring, 0 guides the warps which are woven into and incorporated with the two plies for securing them together. The warps from the upper and lower guide-rings, O 0', pass through and are controlled by the heddles in the first and third frames, L L and thence pass through the slots between the bars A. The warps from the middle or intermediate ring, 0, pass through the heddles of the second and fourth frames, L L and thence also pass between the slats or bars A and these warps are incorporated with and woven into both plies of the hose; hence it is necessary that the second and fourth heddle-frames, L L, of each group should have. a greater length of movement than the frames LL", and to secure this the rods g 9 for operating said frames L L, are connected to the plates or bars M at a greater distance from the shafts N than the rods y g, which operate the first and third heddleframes, L L

Upon each of the shafts N is secured a pinion, h, through which it may be turned, and

near the bottom of the loom are two horizontal bars or rods, P, which cross each other at right angles and each of which is offset to one side, as shown in Fig. 2, so as to pass the shaft F.

To the ends of the bars P are secured racks t, which engage with and rest upon the pinions h, and which are sunken or recessed, so that they will remain in engagement with the pinions h, and as the bars P are reciprocated the shafts N, which are diametrically opposite each other in the loom, will be turned one-half a revolution alternately in opposite directions, and will thus simultaneously shift the groups of heddles which are diametrically opposite each other.

One of the rack-bars, P, is slightly bent or offset upward, so that it may pass over the other bar, as shown in Fig. 1. v

Upon each bar P are journaled two rollers, j; and Q designates a single cam on the shaft F,which operates upon the rollers j and serves to impart the proper reciprocating motions to the bars P. The form of the cam Q is shown in Fig. 2.

A loom having my improvementsapplied may be used for weaving a single-ply hose,

when one set of warps are omitted, in which case the shuttles belonging to that set of warps may be allowed to remain in their raceways, and will run therein in the same way as they do in weaving, but without producing any effeet on the warp which is in the loom and which is woven with the wefts from the other set of shuttles.

What I claim as my invention, and desire to secureby Letters Patent, is-

1. The combination of two complete circular raceways, co-operating shuttles, one or more on each of said raceways, and mechanism,substantially as described, for imparting continuous motion to all the shuttles simultaneously, each on its own raceway, substantially as and for the purpose herein set forth.

2. The combination, with two complete circular raceways, of co-operating shuttles, one

or more on each of said raceways, and mechanism, substantially as described, for imparting continuous motion to the shuttles on the two raceways simultaneously in opposite directions, substantially as and for the purpose herein set forth.

'3. The combination, with two complete circular raceways, of cooperating shuttles, one or more on each of said raceways, mechanism, substantially as described, for imparting continuous motion to the shuttles about the two raceways, and shedding mechanism common to the shuttles on both raceways, all substantially as herein described, for the purpose of weaving a two-ply circular fabric.
