IMPROVEMENT IN MACHINES FOR MAKING HYDRAULIC AND OTHER HOSE PIPESl Specification forming part of Letters Patent No. 173,6 l6, dated February 15, 1876 application filed October 25, 1875.

. To all whom'z't may concern Be itknown that I, JAMES E. GILLESPIE, of Boston, in the, county of Suffolk and State of Massachusetts, have invented an Improvemerit in Machines for'Manufacturin g Hydraulic and other Hose Pipe, of which 'thefollowing is a specification:

This invention relates to a mechanism for manufacturing india-rubber-lined hose for hydraulie and other purposes, and is an improvement on Patent No.163,925, June 1, 1875, granted to me. -,In such machine the warp-carriers have pivoted inclined feet adapted to fit grooves in a rotating surface or plate, and the feet cross each other .as the carriers are moved by the action of the plate to form sheds in the warp for the passage of the weft-threads that pass through guides projecting from the rotating plate and adapted to lay their threads as wefts between the warps. 1

. In this present invention like carriers and feet are employed, and they operate in the grooves in the plate in the same way, but the struction of the plate forms one feature of this in ven tion;

The invention also consists in a tension device supported on the carrier and adapted to bite and hold the warp-thread until-released V by the carrier-weight; also, in mechanism to fold a piece or strip of india-rubber, or its equivalent, about a mandrel, into which steam maybe introduced,'lapping one edgeof the strip over the other, the lapping being in the direction of the length of the tube, and in connection with such an apparatus I employ A, a mechanism for weaving a fibrous covering over the india-rubber, to be formed'as hereinafter set forth.

Figure I'is a side elevation of a machine embodying, this invention. Fig. 2 is a top viewof 'the warp-carrier-operating grooved plate; Fig. 8, a carrier detached and enlarged; Figs. at and 5, views of the warp-tension device; Eigs. 6 and -7, th e weft-tension; and Fig.

8, a detail of the mandrel, over which the tube is formed.

In this invention the frame of the loom is of of the hollow shaft is secured a hub, I), having projecting therefrom a rest-plate, 11 on a level with the top plate a, and provided with holes 0, for attachment of the forked warp-carrier guides 0 each guide being held by a screw passing therethrough and into the holes 0. In Fig. 2 is shown in dotted lines one pair of these guides. These guides receive the heads 0 of the warp-carriers, one shown detached in Fig, 3, and the pivoted feet (1 project into grooves d 61 formed in the warp-carrier-actuating plate 6, arranged at top of a sleeve 0, provided with a gear, 6 and fitted about and so as to turn on the hollow shaftc the plate 1 6 deriving motion from the gear fon the main shaft f, operated in any suitable way.v This plate 0 carries the weft-guides f the pivoted feet (1 rest in the grooves d (1 and,as the plate rotates, the warp-carriers are crossed from one guide, a, to its opposite guide and across the groove between the ends of the carrier guides, in which the weft-guides travel, all in the manner described in the patent referred to, to which reference is made, the warp and weft threads passing over the cup 9, also used in such patent, and provided with a pipe, supplied with liquid or plastic indiarubher, or its equivalent, or suitable water-proofing or cementing material, to be forced through the pipe 9- into the cupg, and against and between the india-rubber lining g and outer woven covering h. In this instance the cup 9 is separate from the mandrel. 7L about which the india-rubber lining is formed, and the fibrous covering is woven, and it is supported by the standard h -and the pipe 9 the latter passing out through the bottom of the shaft (0. (see Fig. 1,) and receiving its india-rubber solution from a proper source. The mandrel h is connected by means of a projection, i, with the hub b and stands above and substantially in a line withthe opening in the hollowshaft c while attached to another portion of'such hub by a projection, 1 is a longitudinally slotted folding guide, i, and the india-rubber lining led into the lower end of the hollow shaft of is folded about the mandrel h by means of the guide 1', surrouiuling, but not touching, the mandrel.

This rubber lining is shown in section-lines in Fig. 2, with-the mandrel within and the guide outside of it, the edges of the in'dia rubher being lapped one over the other. A press er-roller,.j, on an adjustable arm, j, controlled by a screw 'i presses the lapped edges of the india-rubber together, such edges having been previously wet or moistened, preferably with benzine or equivalent, or with suitable cement, to cause the edges to unite firmly and form a water-proof sea-n1 or lap.

I may heat the inner sideof the mandrel or the guide by passing steam or water through a pipe, as at k.

I intend to apply benzine, or a preparatio thereof, or other softening material, to the .edges of the india-rubber, during the process of folding, by means of a brush, or through a or water-pipek is led, and inside the chamber a is placed a pipe, 10 open at top, and into and from the open top of which, -and within the india-rubber lining, may be blown chalk or its equivalent, the same-being allowed'to drop and cover or coat the inner side or surface of the lining material, to prevent it from sticking to the mandrel. After the lining is folded or made into a tube the covering h is woven thereon, and a quantity of liquid india-rubber,

or an india-rubber or cementing compound of any well-.known kind, or such as used when securing rubber within fibrous tubes, being expressed from an annular opening in the top of the cup 9, between the liningg and covering h, the preparation forced between the lining and cover being preferably such a preparation of india-rubber as will vulcanize and cause a firm and close adhesion and union of the covering'and lining.

Referring to Fig. 2, the plate 0 is designed to rotate in the direction of the arrow there on; and it will be noticed that the ends I of the crescent-shaped or dividing ledges l are sharper than the edges 1 and pieces m in, forming the walls of the groovesd d are undercut, as shown in dotted lines, Fig. 2, and between the ends I l are placed adjustable pieces m with friction-rollers n.

I When the part 0 of apivoted foot of a warpcarrier is to pass from either of the positions a of either groove to either position 01 or to was re cross the points where the two grooves inter sect, then one of the small anti-friction rollers a, or a projection on m meets the forward portion of the pivoted foot at one side, and throws it quickly to the side of the end l farthest from it, the enlarged or thickened end l of the crescentshaped ledge 'l acting at the same time on the opposite side of the foot, back of its pivotal point, throwing the free end of the foot quickly away,'or so that it passes into the cut-away or recessed parts of the walls of the pieces m or W, thereby rendering the crossing of the feet from one part of the groove to another part more rapid and certain, thereby preventing the carriers from dwelling so long as to become caught when passing from an outer to an inner carrierguide, and crossing the usual circular groove or path w, in which the weft-guides move.

With this-construction the carriages are changed more rapidly than usual, and the loom may be run faster. Each warp-thread passes from a spool, 0 through a hole in a guide, 0 on which (and free to slide) is a carrierweight, 19, provided with a roller, 12. A tension-lever, p", is pivoted to the guide 0 and a spring, q, acting on the adjusting screw or device q bears the shoulder g (see Fig. 4) of the lever 19 with the desired force against the warp-thread which passes between the guide 0 and shoulder The warp, after passing through the hole in guide 0, is passed between the shoul ,der q -and the guide, then over and in the grooved portion 1' of the lever 21 about the roller 12 over the roller 4" to the weavingpoint. The weight 19 takes up and holds the slack warp; but when the slack is used up the weight is raised, and strikes the end of the lever, rocks it, and releases the warp from the action of the lever, and, after the formation of enough slack warp, the weight descends, releasing the lever and the spring q, then moves the lever to bite the thread.

A detail of the weft-tension is shown in Fig. 6. Each weft-thread passes from a spool,

s, over and about a tension device composed.

of a truncated cone, 8 with a connected hub, 8 The weft is wound from the larger to the smaller end of the cone so as to gradually crowd the coil down the cone, yet not to permit thestrands to overrun each other.

About the hub is placed ayielding com-' pensating strap, t, preferably of light metal, one end being fixedand' the other being passed through a slot or opening in a standard, t

whereit is provided with a spring, t one endname V e hereto the hub, the spring willyield and-allow the tensiondevice or wheel toturn, and the strap being then loosened will allow the 7 wheel and hub to move.

This device is applicable for use as'a ten sion for the thread in a se\ving{n1achi11e, In-

- (see dotted lines,) I may make the grooves or paths more or less irregular or cam-shaped, and the crossings may take place at any desired intervals, the free ends of the inclined. pivoted feet being adapted to be swung by the projections and ends. 1 of pieces 1 or equivalent pieces of other than crescent-shape between the grooves, the free ends of the pivoted feet passing intothc spaces cut away in the side walls of the grooves;

It is evident the angle formed by the grooves at theircrossings maybe, under this arrangement, more or less sharp.

ltwi'll be understood that at thecrossing points of the grooves, as herein shown and described, the grooves'do not in curvature accord with the curve of the pivoted feet, and the spaces formed bycutting away the walls of the grooves permit-the ends of the feet to move therein.

1. The warp carrier-actuating plate, its projections 01., pieces at W, and ends '1 PM different sizes, in combination with the warpcarriers and the inclined pivoted feet to operate the carriers quickly, substantially as described.

' 2. The combination, withthe warp'oarrier, of an adjustable thread-holding or nipping device, and a weight to operate the threadholder, substantially as described.

3. A guide and mandrel to form and fold a lining of india-rubber, and warp and weft' carriers adapted to weave a tubular covering about the lining, in combination with a cup to deliver a rubber or other cement on the outside of the folded lining.

4. The cup and steam-heated mandrel, sep

arated therefrom, butwithin the cup, in combination with a pipe'for'discharging chalk or equivalent within the folded lining, substan- ,,tially asand for the purpose described.

5. A guide and mandrel adapted to fold .a

strip of india rubber into tubular form, in.

combination with a cup to contain liquid rubber to be expressed or applied to the outside of the folded rubber tube, substantially asdescrib'ed.'

6. The mandreland folding guide adapted to fold and lap' the edges of a strip of indiarubber, to form a' tube in combination with warp and weft carriers and mechanism adapted .to operate them, to weave a tubular covering on the folded and lappedtube, substantially as described.

7. The carriers and inclined pivoted feet connected at one end with the carriers, in com-' bination with a grooved plate having the side walls of the grooves cut ,away below the top surface of the plate, to receive the free ends of feet thrown into such open spaces, when the curvature of the grooves does not accord in curvature with the foot.
