SLAT-AND-WIRE-FABRIC LOOM.

SPECIFICATION forming part of Letters Patent N o. 517,058, dated March 27, 1894;

Application filed May Z4. 1893.

To all whom it may concern..- i

Be it known that we, CHARLES E. PARKS and LOBEGOTT MOLLART, citizens of the United States, and residents of Watertown, in the county of Jeerson, and in the State of Wisconsin, have invented lcertain newand useful Improvements in Looms for Weaving Slat-and-Wire Fabrics; and we do hereby de- Clare that the following\is a full, clear and exact description thereof.

Our invention has for its object to simplify and cheapen the production of slat-and-wire fabrics; and it consists in certain peculiarities of construction and combination of parts hereinafter described with reference to the accompanying drawings and subsequently claimed.

In the drawings: Figure l represents our loom in horizontal section taken on line l-l lof Fig. 4; Fig. 2, a detail horizontal section illustrating a wire-guide at the free end of a*- warp-spreader; Fig. 9, a plan view of a slatguide, and Fig, l0, a detail plan view with parts broken away illustratinga slat-feeding mechanism.

The frame of our loom comprises a topplate A and a base B joined by vertical rods arranged at suitable intervals. The top-plate A has a hinged extension A provided at its free end with'a bearing for a journalb at the upper end of a longitudinally slotted roller C, and adjustable on this roller is a disk D or other suitable supporting device for the slat and wire fabric wound on said roller in the manner hereinafter specified. The lower end of the roller is stepped upon the upper side of a pulley E loose on a stud c that is screwed into a right angle depending'portion B of the base B and a collar d on this lower end of said roller is provided with lateral Serial No. 475.323. (No model.)

by a belt F that runs on another pulleyG-fast to a vertical shaft H having its bearings on .the loom-frame, the tension of the belt being regulated by a suitable tightener. rI`he tightener herein shown comprisesy rollers g and h, loose on studs projecting from a horizontal yoke I centrally secured to. a vertical rod .I that has bearings on the loom-frame, and fast on the upper end of this rod are arms t' andj, the former serving as a hand-lever, and the other as a support for a pivotal detent lo which latter engages a rack m on the topplate of said loom-frame to hold said tightener in the position to which it may be adjusted. The tension on the belt is such that it will slip on the pulley E when the fabric wound on the roller C is tight, the wind of said fabric being necessarily intermittent.

Fast on the shaft H above specified is a disk K having its upper side providedwith a peculiar form of cam-groo ve as best illustrated in'Fig 2, anda bevel-gear wheel L also fast on said shaft meshes with a corresponding pinion M upon a horizontal shaft N that has its bearings on the higher portion B of the loom-frame base and is provided with tight and loose pulleys for a drive-belt. A spurwheel O also fast on the shaftN meshes with a corresponding pinion P on a counter-shaft Q having suitable bearings on the loom'base and provided with a pulley R for aver-tical belt S that runs through a slot in saidlo'ombase against an anti-friction roller Ty and drives another pulley U on another horizontal shaft -V arranged in bearings depending from aA yoke W fast to the under side of the topplate A of the loom-frame. The shaft V carries a feed-roller X provided with a frictioncollar 'n for impingement against another feed-roller Y having a shank p arranged to turn in a yoke Z that has a pivot-connection q with the under side of the top-plate A of the loom-,frame and a -lug r that engages a transverse slot s in said top-plate. By means of a spiral-spring t engaging lugs on the pivotal yoke Z and a depending flange of the top-plate the feed roller Y is 'kept normally in contact with the friction-disk on the other parallel feed-roller X as best illustrated by Fig. 10.

IOO

Bolted or otherwise suitably secured to the yokes W and Z beneath the same are parallel plates u one of which has an end thereof provided with a lateral extension u overlapping the other, although it would be no departure from our invention to substitute a single plate having a suitable slot therein. In either case we provide a guide that prevents slats, fed down between the adjacent rollers, from de viating out of the path of beaters hereinafterspecified. A

A lateral extension A2 of the plate A is provided with a stud w that engages a base-disk C and a drum D', the later being in frictional contact with the disk and provided with a series of peripheral passages at regular intervals, these passages being for the reception of slats that successively come into register with an` opening in said plate and drop down between the feed-rollers above specified. The feed-rollers being normally in frictional contact and under rotation, a slat caught between the same'is quickly run down and one of these rollers has the yielding arrangement above specified to compensate for inequalities or varying thickness in slats.

At intervals ou the periphery of the drum, corresponding to the passages therein, are lugs y whereby we virtually provide a ratchet that is engaged by a spring-controlled pawl z pivotally connected to a spring-controlled arm E pivoted to the top-plate of the loom-frame. This pivot-arm has its free-end in the path of a cam b on the vertical shaft H above specified and thus an intermittent rotary motion is imparted to the drum to bring the slat passages therein into successive register with the feed-opening in the top-plate of the loomframe. The upper end of the shaft I-I is provided with a crank F and this crank is linked to the upper end of a vertical rod G on which we arrange a series of beater-arms H preferably heldin place by set-screws and consequently adjustable as to position. The rod G is fast in cross-heads I loose on guides J secured to lateral projections c on the top and base-plates of the loom-frame, and the lower end of said rod is linked to a wrist d on the pulley G fast to the shaft H, this wrist being positioned in line with the outer end of the crank F on said shaft.

An arm K fast on the rod G has a lug e' in engagement with a cam-groove in a horizontal plate L suspended from the higher portion of the loom-base, the contour of this cam-groove being two straight parallel paths f" and g the latter one of which has curved extremities joining the other. Pivotal springcontrolled gates h and t" are arranged at the junctures of the paths embodied in the camgroove, and these gates yield in one direction to the travel of the lug e on the arm K thereby permitting said lug to divert from one to the other of said paths at certain intervals, hence when the cross-heads travel in one direction, the beater arms are dropped from their working position to clear a slat fed to the warp, but on the reverse travel of said crosshead said beater-arms are exerted against the (for the time being) last slat in the fabric.

Fast on one of the brace-rods of the loomframe at suitable intervals are slotted plates M that serve as slat and fabric guides, these guides being provided with spring metal wings j that bear against said fabric and tension the same against the action of the beater-arms. Fast to other brace-rods of the loom-frame are supports N in the form of plates for wire-spools O these supports being provided with suitable openings for engagement with spindles P that engage suitable bearings on the top-plate and base of said loom-frame.

Shafts Q and R', parallel to each other and the shaft H, have their bearings in the loomframe and connect with each other bya toothgear as shown inFig. 3. Adj ustably secured to these shafts Q and R', are spreaders S and T', having flanged rear ends provided with eyes for the passage of wire drawn from the spools. Each spreader is provided with a series of parallel sheaves 7c' on fixed bearings, a spring-hung sheave m', forward of the former sheaves on a plane outward therefrom and still another sheave fn havinga fixed bearing forward of the one that is spring-hung. The wirefrom aspool is passed th rough the eye at the rear end of a relative spreader and then in and out against the several sheaves in the manner best illustrated in Fig. l, after which it is carried through a guide p in the form of a perforated pin drove into an opening in the grooved forward end of said spreader, this guide and grooved spreader-end being shown in detail by Fig. S.

In practice the forward ends of the wires are secured to a substitute for the roller C until enough of the fabric has been woven to permit of its engagement with the slot in said roller when positioned as shown inFig. 4, this engagement being clearly illustrated in Fig. 1. A roller U is arranged intermediate of the roller C and gnidep1ates M in such position as to prevent strain on these plates as said fabric is wound on said roller, the draw of the fabric being always from the same center. The spreaders S', T are rocked at certain intervals by their respective shafts to cross the wires and thereby establish a shed for each slat. As herein shown the spreaders are so arranged that adjacent to the edges of the fabric the wires are double and cross eachother on opposite sides of each slat while the intermediate wires are single and cross from one side of a slat to the opposite side of a succeeding slat.

The necessary rock of the spreader-shafts Q and R', is governed by the time-mechanism consisting of the cam-grooved disk K and a crank V on the former shaft having a pivotal shoe lr engaging'the groove in said disk, this rock taking place each timeaslat is beat up in its shed, and just prior to the instant the beater arms begin their movement out of IOO IIO

working position. The cam-groove is necessarily of such contour that after a rock of( the spreaders they will remain stationary While a slat is being fed into the warp and beat up to place, and as shown in Fig. 2, said carngroove is virtually two concentric half-circles joined by two segments of equal radius struck from different centers eccentric to that of the half-circles and crossing each other in line with the latter center. As a result of `this cam-contour the crank V is only actuated when the eccentric segments travel against the pivotal shoe fr', and remains stationary when this shoe is in either of the concentric half-circles.

Adjustable on the forward end of the counter-shaft Q is a bevel pinion W adapted to be brought into mesh with ,a corresponding gear-wheel X fast on an arbor Y that has its bearings on the loom-frame and carries' an adjustable saw Z, the latter being brought int-o use when it is necessary or desirable to v split a web of fabric coincident with its production. When this splitting operation takes place We prefer to arrangev spreaders and wires in such a manner that the latter are double and cross each other on opposite sides of the slats adjacent to the inner edge of each strip of fabric.
