PILE-WIFE RETAINER FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 788,031, dated September 1, 1903.

Application filed June 25,1903. Serial No. 163,065. (No model.)

T0 LZZ whom, t may concern:

Be it known that I, HARRY HARDwteK, a citizen of the United States,residingiu Philadelphia, Pennsylvania, have invented certain Improvements in Pile-'Wire Retainers for Looms, of which the following is a specification.

My invention consists of cert-ain improvements in the pile-wire retainer for looms shown in my previous Letters Patent No. 529,615 and dated November 20, 1894, the object of my present invention being to so mount the retainer th'at inspection of the woven fabric or access thereto will not be obstructed by the support for the retainer.

In the accompanying drawings, Figure 1 represents suiieient of a loom to illustrate the application of my improved form of pilewire retainer thereto, and Figs. 2, 3, and 4E are similar views illustrating other embodiments of the invention.

The pile-wire retainer forming the subject of my before-mentioned Letters Patent consisted ot' a series of hooked ngers projecting inwardly from a bar mounted above the breast-beam of the loom,.said hooked fingers being so disposed as to engage the last-inserted pile-wire of the series and maintain the same in the upright position against the pull of the pile-warp threads thereupon, thereby preventing the deflection or bending downward of any portion of said wire, and thus insuring the formation of the desired upstanding row of pile-loops across the fabric. The presence of the supporting bar above the fabric was, however, objectionable in some cases, because it interfered with a complete view of the fabric in `its passage from the beating-up point t'o and over the breast-beam and also prevented free access to all parts of this portion of the fabric. In order to overcome this objection, therefore, I have now devised a plan of supporting the retainers which without interfering in any way with the performance of their intended functions leaves the woven fabric as free for inspection or access as that of an ordinary loom,

In the drawings, 1 represents the breastbeam of the loom, and 2 ing lay with its reed 3.

` In the construction shown in Fig. 1 each of the pile-wire retainers 4 (of which as many may be employed as the necessities of the case suggest) is supported upon the under side of the breast-beam and extends thence to a point which is in the rear of the lay when the latter is fully retracted, at which point the retainer is curved upwardly to a position adjacent to the top of the reed and is then 6o carried forwardly through one of the spaces of the reed, terminating finally at the beating-up point, so as to properly engage with thelast-inserted pile-wire 5 and maintain the same in the upright position, each successively-inserted pile-wire acting upon the under face of the hooked retainer, so as to lift the same, and the hook, owing to the resiliency of the retainer, then snapping back of the pile wire when the latter reaches the 7o beating-up point. ABy thus mounting the hooked retainer the same has a longer shank than the retainer vset forth in my former patent. Hence the resiliency of the retainer as regards vertical movement is increased, added resiliency being due to the curve of the shank. This vertical resilience, however, detracts in no material measure from the longitudinal rigidity of the retainer, which enables it to resist the strain upon the pile- 8o wire, tending to turn the same from the upright position.

In that embodimentof my invention shown in Fig. 1 the shank of the retainer is carried beneath the shuttle-race of the lay; but in the construction shown in Fig. 2 the shank of the retainer is bent upwardly and passes through a slot or recess in the shuttle-race before being curved upwardly at the back of the reed, all that is necessary in this case 9o being to insure suiicient space between the part of the swing- 5o upper and lower members of the retainer to permit of the passage of the shuttle through the open shed of warps.

In that embodiment of my invention shown in Fig. 3 the shank of the retainer is mounted upon a bar 6 in the rear of the heddles or harness and passes thence forwardly between adjoining Wires, threads, or bars of said heddles or harness and through one of the spaces of the reed, terminating, as before, at the beating-up point, so as to engage with the last-inserted pile-Wire 5.

In each of the constructions shown in Figs. l, 2, and 3 that portion of the retainer which passes through the reed serves to prevent lateral deflection of the retainer in the same manner as the projecting end of the retainer shown in my former patent. This, however, is not absolutely essential to the proper carrying out of my invention, and in Fig. et I have shown a construction in which a retainer mounted at the rear of the loom passes over the top of the reed and is bent down in front of the same at the beating-up point, so as to engage the pile-Wire.

Having thus described my invention, I

claim and desire to secure by Letters Patent- l. The combination of the lay and its reed with a pile-Wire retainer having a portion for engaging the last-inserted pile-Wire, said retainer passing to the rearf-of the reed, and a support for said retainer, substantially as specified.

2. The combination of the lay and its reed with a pile-Wire retainer having a portion for engaging the last-inserted pile-Wire, and a support for said retainer, said retainer passing through the reed, substantially as specilied.

3. The combination of the lay and its reed with a pilewire retainer mounted upon a support below the Woven web, said retainer extending from its support to the rear of the lay and being thence carried forwardly through one of the spaces of the reed and terminating in a wire-engaging portion at the beating-up point of the loom, substantially as specified.

1l. The combination of the lay, having a slotted sh Little-race and a reed,With a pile-Wire retainer mounted upon a support beneath the Woven web, extending thence through the slot in the shuttle-race to the rear of the reed, thence forwardly through one of the spaces of the reed and terminating in a Wire-engaging portion at the beating-up point of the loom, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

HARRY HARD WICK.
