rics, of which the following is a specification.

The object of this invention is to provide a loom for weaving tubular fabrics which may be employed for hose, tubing, tires, belting, or other purposes, and particularly to provide a mechanism for weaving a fabric consisting of a plurality of tubes concentrically arranged or included one within the other. To this end a flat or lane warp is operated to form a number of plies twice the number of tubes to be woven. For example, if two tubes are to be woven, one inside the other, the warp is operated to form four plies. This is done by employing eight harnesses and operating the Same as hereinafter described. A shuttle is provided for each tube to be woven. Thus in the example above taken two shuttles and mechanisms for operating the same are provided. A shuttle-box is provided at each side of each reed-space. These parts' are so arranged in the example chosen for illustration that one shuttle will pass in one direction through the u per one of the intermediate plies and the ot er Shuttle will pass through the upper or--outside ply. The first shuttle will return through the lower one of the intermediate plies, and

'the second shuttle will return through the bottom or outside ply. By this arrangement two tubes will be woven one inside the other.

Suitable binder-warps are-introduced and may be woven into the fabric in a number of ways. If some of the binder-warps are used to bind the two upper plies together and the remainder of the binder-warps to bind the two lower plies together, the resulting product of two tubes, one inside the other, will bev bound together, but the inner tube will be left in open condition. This operation is emloyed when it is desired to weave a hollow abric, such as hose, tubing, or tires. If the binder-warps are operated to bind all the plies together, two collapsed tubes, one inside the other, will be produced, and the tubes Will be bound together to retain their flat or collapsed position and relation to each other. This is a product well .adapted for belting. The loom has been arranged in multiplethat is to say, to form al loom which will weave a plurality of products-the shuttleboxes and mechanisms being combined, so i that the intermediate shuttle-boxes can be used in connection with the fabric woven at each side thereof, whereby there will have to be a number of shuttle-boxes exceeding the number of roducts by only one. Wlth a loom thus esigned to weave two products there need'only be three shuttle-boxes. With a loom designed to weave three fabrics there need only be four shuttle-boxes. With a loom designed to weave four fabrics there need only be five shuttle-boxes, &c. The shuttles are preferably actuated by positive motion.

The invention further consists of improved details and mechanisms for operating the parts.

A loom embodying this invention is illustrated in the accompanying five sheets of drawings, in which- Figure 1 is a front elevation ofpart of a' loom constructed toeinbody the invention.

Fig. 2 is a side elevation thereof. Fig. 3 is `an elevationv takenfrom the opposite side relatively to Fig. 2. Figs. 4 an 5 are front elevations, on an enlarged scale, illustrating the shuttle-box mechanism. Fig. 6 is a cross'- sectional view through one of the shuttle-box mechanisms. Fig. 7 is a detail of the gearing and connections for actuating the shuttles. j

Figs. 8 to 15, inclusive, are diagrams illustrating the operation of the shuttles. Fig. 16is a diagrammatic representation of the. operation of weaving. Figs. 17 and-18 are diagrammatic views of a tubular product, Fig. 17 representing the outer tube partly cut away to s ow the inner tube and Flg; 18 re resenting the fabric partly open to show t e IOO which power is applied and which has a Hywheel and the usual hand-wheels and a clutch operated by a handle 21 so that the loom can be thrown intoand out of operation inthe slide guides, there usual way. A pinion 22 on the drivingshaft 2() meshes with'a large gear 23 on the crank-shaft 24, which crank-shaft has a plurality of crank-arms 25, vwhich connect Iby pitrnen Q6-to links' 27, pivoted at one end to the framework and at the other end to links 28, which are connected to the lay-frame 2'9,

ivoted on the usual shaft290 whereby the i ay will be vihrated back anV forth on its pivot-shaft.

'Suitable harness-frames 30 are arra ed to being a set ol tvi'fo frames for each ply of the fabric land two frames for the binder-warps. These harnessfra'me's are arranged to carry theusu'al heddles. In the articular illustration shown there 'are ten arnesses, two harnesses for ,each 'or the four plies or the fabric and two harnesses for the binder-warpls, Ithe binder- 'War'ps bein .operated by the 'arness-frames nearest thefront of the loom.

The 'war'ps 'are drawn from any suitable source and are led into the loom around rolls 3l, 32, and 33 and around a whip-roll 34. This whip-roll 34 isvmounted in brackets 35,

ivoted concentrically with the roll 33. The brackets 35 are connected b links 36 tothe links 27, which form part '0 the mechanism for operating the lay. The ends 'oi the links 36 are slotted, as shown, and engage pins secured to the brackets v85. The. arrangement is such that as the lay beats up from the position shown in 3 to the position shown in F 2 to beat the filling into pla-oe the whi rol 34 will be moved back to tight-en t e war so that the fabric will be tight while being eaten 'up and the tension will be relaxed during She ding. The lander wapaI are drawn fromv an' suitable source and are carried around t e roll 37 to their frames; From the-heddles the warps pass through the usual reedsSS, carried by the lav.

nected to o erate the harness-frames which control the Ebinder-'wa s, s o that by substituting diiferent cams t l e binder-war'ps may be laid in the fabric in different Ways.

Each fabric after it is Woven passes out over any suitable uiding device 45 to a takeup device 46, Whic may be of the usual conl front of the machineare of split or removable form and are construction and which it is not necessary to describe in detail in this case.

Arranged at each side of each reed-space are shuttle-boxes, which will now be described.

Vertical guides 47 are formed or secured to the lay-frame 29, and fitted to slide on the .same are the shuttle-boxes 481,'each of which in the construction shown has two shuttlecompartments. The upper position of the shuttle-boxes on the guides may beV determined by stop-screws 49. The shuttles are designated by 50. Each shuttle 50 as shown in Fig- 6, has a rack 5l at the back thereof 'and each 'shuttle is provided with the usual 'appurtenances wherebya c'o can bel carried by the same and the filling ed out throu' h any of the usual outlet devices 53A. On t e front end of the shaft 40,' as shown in Fig. l is a ca'mf54 for operating the shuttle-boxes. Engagingthis cam is a roller 55, mounted on the end of a pivote'd lever 56, which is 'connected by a link 57 to a sliding bar 58. Rocking levers 59 are pivote'd at 60 and are `con- 'nected to be operated from the slide-bar 58. The ends of these rocking levers ,are connect- 'ed by links 61 to 'the shuttle-boxes. The rocking lever 59 at the left-hand en'd of the machine is ractically only a half-lever and is connected to but `one shuttle-box. These connections are arranged so that the shuttlehoxes are operated relatively oppositely on each side of `each reed-space-that s to say, the shuttle-box at one side thereof moves down as the shuttle-boxat the other side there'oi` moves u and vice versa.

. inthe particu ar loom illustrated the rela'- tion between the spiral gears and spiral pinions is eight toene, so that the shaft 4c turns on'ce foreach eight beats of the loom, and the cam S4 is designed so that the shuttle-boxes chan 'e positions relatively to each other at e'a'h eat of the loom. l

The mechanism for operating the` shuttles will now be described.

On the shaft 43 is .a mutilated ve'ar 62, which has four toothed sections. 'Iivo pinions 63, having teeth properl designed, are journaled in the framing, an each carries a crank 64. The cranks 64 are connected by links 65 to a lever 66, pivoted on a lever 6 7, which extends down from a ivot on the framing. The operation of this mechanism is such as to swing the lever 67y by a two-step movementr to` the right or to lthe left, with a dwell between each of these movements and a dwell at each of lits extreme positions- IOO IIO

that is to say, for example, -the upper pinion will iirst turn one hundred and eighty deees to. swing the lever 67 to the right. here will, then be a short dwell. The lower pinion will turn one hundred and eighty degrees and swing the lever 67 still farther to he right. There will then be a short dwell.

The upper pinion will turn one hundred and There will t to its intermediate position.

Then the lower pinthen be a short dwell.

' ion will turn one hundred and eighty degrees and will swing the lever 67 to its extreme left-hand osition. There will then be a short dwel completing the cycle. The lower end of the lever 67 is connecte by a universally-jointed link to a rack 69,

which is fitted to slide in bearings 70, carried by the pivoted shaft 290 of the'lay-frame. This rack engages a pinion 71, mounted on a short shaft which carries a gear 72, which meshes with a pinion 73, secured on a vertical shaft 74, journaled in bearings carried by the la g v 5h long rack 75 is itted to slide in the la under the shuttle-boxes. The vertical sha t 74 carries a pinion 76, engaging the long rack 75. Journaled in the lay so as to come at each side of each shuttle-box are shafts 77.. Each of these shafts 77 has a pinion 78, .which meshes with the long rack 75, and each of these shafts has a pinion 79 at its upper end. These pinions 79 constitute the shuttle-driving means.

The construction is the same for each of the shuttle-boxes, except that at the righthand side of the left-hand shuttle-box the vertical shaft 74 extends up and carries the right-hand shuttle-driving pinion 79. These shuttle-driving pinions 79 are arranged in position so that when the shuttle-box is in its lowest position, as shown in Fig. 4, the up er shuttle in that box will be operated an so that when the shuttle-box is in its raised position, as shown in' Fig. 5, the lower shuttle in that box will be operated. The ,pinions are operated by the gearing before described so that one shuttle and then the other shuttle will be movedfrom one box over to the other and then one shuttle and then'the other shuttle will be moved back. A

The intermediate shuttle box-that is, each shuttle-box between an adjacent set of harnesses-is designed so that it is used ,for the shuttles of the `fabric at each side thereof.

When the shuttle-box is lowered, the upper shuttle will be brought into mesh with the shuttle-driving pinion and the lower shuttle will be moved out of mesh, and when a shuttle-box is raised the lower shuttle will be brought into'mesh with the shuttle-driving pinion 'and the upper shuttle moved out of mesh. v

The operation is shown in the fifth sheet of drawings 'in connection with a four-ply or double. tubular fabric and in connection with the weaving. of two ie'ces of fabric. Calling the shuttles for the eft-hand fabric A and B and the shuttles for the right-hand fabric C and D, the operation is as follows, starting with the parts in the position shown in Fig. 8: Atthe first movement shuttles A and D pass to the right to the position shown in Fig. 9.

`8 and completing the cycle.

Y and was not devised by me.

The shuttle-boxes then change as shown in Fig. 10. The shuttles B and C then pass to the right, as shown in Fig. 11. y boxes then change as shown in Fig. 12. y The shuttles A and D then pass to the left, as shown in Fig. 13. The shuttle-boxes then chan e as shown in Fig. 14.v The shuttles B and then pass to the left, as shown in Fig. 15. The shuttle-boxes then change, bringing the parts back to the position shown in Fig. It will be seen that the shuttle B follows the shuttle A both to the right and to the left and that the shuttle I) similarly follows the shuttle C. By this operation the shuttles will properly pass through the warp, the lay beating up just after each movement of the shuttles. Now considering the fabric woven by the shuttles A and B, the warp is operated to form four plies a, b, c, and d. Shuttle A will pass over throu h the top one of the intermediate plies a.

AShutt e B will pass over through the upper or outside t. lShuttle Awill pass back through the lower one of the intermediate plies c and the shuttle'B'will pass back through the lowest or outside ply d. This, in connection with Y the harness-motion and the beating up ofthe fabric .by the la ,will weave two tubes T and T,-one inside the other, a'sshown in Fig. 17. By using cams 44 to operate the harness- 'frames of the binder-warps so that the binder-warps will tie the plies a and b together andso that another part of the binderwarps will tie the plies yc and d together the two tubes will bebound to each other and a double hollow fabric will be woven, suitable for hose, tubing, or tires, as shown in Figs. 17 and 18. If cams are used to cause the The shuttle-4 binder-warps to ytie the four plies together,l l

the product will be a four-ply fabric consistin of two tubes, one inside the other, the two tu es being collapsed' and bound together to form a product suitable for belting. In Fig. 19 I have shown an arrangement of binderwarps in which part of the binder-warps will tie the plies a, b, and c together, while the other part of the binder-warps will tie the plies 1b, c, and d together-that is to say, in the fabric illustrated in Fig. 19 the binderwarps do not extend completely through the fabric, one set of b inder-warps extending part way through from one face of the fabric and the other set of binder-warps extending art way through from the other face of the falliric. This form of fabric has been found in practice to be lparticularly well adapted for use as belting; ut although I have herein illustrated and described this form of fabric for thepurpose of clearly explaining the character of products which can be made on a loom constructed according to this invention it is to be understood that this particular form of fabric forms no part of my present invention It is of course within my invention to divide the warp into a greater number of plies application of such shuttle'- oxes to any parfor weaving more ythan two tubes' inside of each other, and of course the loom may be designed to weave as many fabrics abreast as is t ou ht desirable, depending upon the width o product produced.

The arranvement of shuttle-boxes and various combinations referred to in the claims nia be used in many other forms of looms, an l have not intended to limit the scope of the claims coverin the same to the ticular classof loom:

The detailsand arrangements' herein described may be greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.
