UNITED S AT-Es PATENT OFFICE.
JAMES E. GILLESPIE, or ISOSTON, MASSACHUSETTS.
IMPROVEMENT INHVDR AULIC HOSE.
Specification forming part of Letters Patent No. 1 73,615, dated February 15, 1876; application filed I November 4, 1875.
To all whom it may concern:
Be it known that 1, JAMES E. GILLESPIE, of Boston, in the county of Suffolk and State of. Massachusetts, have 1nvented an Improved Hose for hydraulic and other purposes, of which the following is a specification:
This invention relates to hose for hydraulic and other purposes; and consists of a three-ply hose, woven, substantially as hereafter described, whereby, when the outer ply or set of warps and outer row of wefts are worn away, the second and third wefts, and the inner set of warps formed by them, will remain serviceable.
Figure 1 represents an end view of this improved hose in cross-section, showing the warp and weft; Fig. 2, an enlarged longitudinal section of the tube, and the other figures indicate details of the weaving process.
This tubular fabric is woven on a circular loom provided with bars or carriers, one for each warp-thread, the warp-thread carriers being selected by a pattern-surface, andoperated to form sheds by cams, and the wefts (three) are carried by three shuttles working in a circular race.
In thedrawings, the warps are represented by figures and the weft by letters.
The inner set of warps are numbered 1 2, and the outer set 3 4, and the inner weft c, the intermediate or binder b, and the outer weft a.
In Fig. 3, suppose the points a b c to represent'weft laid and properly woven, then a shed is-formed by lifting warps 1,3, and 4, and weft c is inserted; then, for the next shed, (see Fig. 4,) lower warp 4 to position occupied by warp 2, and insert weft b,- for next shed (see Fig. 5) lower warp l, and insert weft a, then lift warps 2 and 4. (see Fig. 6) and insert weft c, then lower warp '3 (see Fig.7) and insert weft b, then lower warp 2 (see Fig. 8) and insert weft a, then raise again warps 1, 3, and 4, (see Fig. 9,) as in Fig. 3, and insert weft a, repeating the operation. 7
In Fig. 2, the longitudinal section, it will be noticed that warps 1 and 2 appear only on the inside of the fabric, and warps 3 and 4 on the outside.
Q The wefts a are always in sheds formed between warps 3 and 4.,andwefts 0 between sheds formed in warps l and 2, and the number of intermediate wefts b correspond in number with the wefts c or a, and each weft b holds together, alternately, warps 2 3' and If the outside warps 3 4 should be worn away or broken, and the filling or weft a with it, the warps l 2 and wefts b .0 would yet form an entire fabric;
In all thick woven material heretofore woven, so far as I am aware, the binder warps come to the outside as well as the inside, and ifthe outer warps are worn away the integrity of the fabric is destroyed.
This tubular fabric, made by shedding the warps in "a circular loom in the order de. scribed, makes a superior fabric, one possessing great strength and solidity, and especially adapted to withstand great strain, and all the warps being of substantially the same length are subjected to equal strain, which is very important.
By this invention tubular fabrics are formed in layers, one about the other,.each independent layer havingits warps locked with warps of its adjacent layer, by wefts lying between the wefts proper of each independent layer, every warp being locked by. an intermediate weft.
More than three-ply could be woven on the same principle without departing from this invention.
The set of warps 2, and one or more of the the outer, warp and filling may be worn away 4 and not disturb the inner sets of warps and fillings, as set forth.
2. A hose or tubular fabric of two or more name to this specification in the presence of ply, wherein the outer ply is composed of two subscribing witnesses. warps and weft of wire, and the inner ply of e fibrous warps and weft, the wire of the outer JAMES E. GILLESPIE.
ply not extending to the inner face of the Witnesses: hose, as and for the purpose set forth. G. W. GREGORY,
In testimony whereof I have signed my B. KIDDER.
