T @ZZ 1.072.072?, it may concern.:

Be it known that I, CHARLES E. PARKS, a

. citizen of the United States, and a resident of 'Watertowin in the county of Jefferson, and in the State of lVisconsin,have invented certain new and useful Improvements in Looms for leaving Slat-and-Vire Fabrics; and I do hereby declare that-the following; is a full, clear, and exact description thereof.

My invention consists in certain peculiarities of construction and combination of parts, to be hereinafter described with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a front elevation of my loom, having portions thereof broken away and in section for the purpose of better illustration; Fig. 2, a top plan view partly in horizontal section; Fig. 3, a section on line 3 3 of Fig. l; Figs. l and 5, detail sections respectively taken on lines 4 4 and 5 5 of Fig. 3; Fig. 6, a detail plan view of a gripping device employed in said loom; Fig. 7,a detail View illustrating the crossing of Wires that form the warp of the fabric produced by the aforesaid loom; Fig. 8, a detail plan view, partly in section, on line S 8 of Fig. 9, illustrating, an automatic feed mechanism for the slats that form the filling of said fabric; Fig. 9, a section on line 9 9 of the preceding ligure; Fig. 10, a detail end View of the slat-feed; Fig. 11, a section on line 11 1l of Fig. 10, and Fig. 12 a detail elevation of a portion of the slat receiver and carrier.

Referring by letter to the drawings, A represents supports for the frame B of the loom, and the upper and lower sides of this frame are slotted, as shown at l), to receive the ends c of the inner side C of a slat carrier. Plates d, arranged at certain intervals t0 leave interstices c, connect the inner and outer sides C D of the carrier, and secured to these sides of said carrier are blocks f, in register with the plates and at the same intervals apart, the opposing faces of these blocks being cut away on a bevel, so as to present less surface to slats fed into the receiver and carrier through an opening gin the upper side of the loom-frame. The ends c of the inner side C of the receiver and carrier are connected by pitmen E with cranks h on a shaft F, that has its'bearings t' on the upper and lower sides of the loom-frame, said shaft being provided,

with a bevel gear-wheelj, in mesh with a pinion 7s on another shaft G, arranged in bearings m on a brace-beam H and rear end of the loom-frame.

Loosely arranged on the shaft G is a driving-pulley I, having its hub provided with one section n of a clutch, the other section 0 of this clutch being splined on said shaft and suitably connected to a slide-rod J, the latter being joined to a lever K, as best illustrated in dotted lines in Fig. 1, wherebythe latter clutch-section may be thrown in and out of engagement with the one on the driving-pulley to start and stop the operation of the loom. l The lower side of the loom-frame is recessed opposite the opening g in the upper side thereof to receive the socket end p of a plate L, and when a slat is fed to the receiver and carrier it drops into the socket and is thus properly positioned prior to the forward travel ot' said receiver and carrier, the socket portion of the plate being curved, as shown in Fig. 1, to permit of the slat having an easy rise out of said socket when the aforesaid receiver and carrier is actuated.

Connected to cross-braces M of the loomframe are spring-fingers N, arranged to come on opposite sides of the fabric produced by the loom, and the rear ends of the lingers are preferably serrated, so as to obtain a better grip on each slat that is beat up in the shed formed by the warp-wires as the operation of weaving the fabric takes places. Hereinafter the fingers N will be termed grippers, and attention is called to the fact that the serrations thereon are so arranged as to resist rearward movement of the fabric without interfering with the forward movement ofl the,

Sule.

Journaled in forward extensions q q of the y loom-frame receives a reel Q, that turns there with, and the forward extension q of the upper side of said loom-frame is hinged, so as to be laid back in order that the reel may'be slipped on and off said shaft.

Jonrnaled in the upper and lower sides of the loom-frame, in rear of the slat receiver and carrier, are parallel shafts R R', provided with crosser or spreader arms r, as best illustrated in Fig. 4.-. These shafts are connected by gear-wheels s s', and the shaft R is provided with another gear-wheel t, that meshes with a pinion u on the shaft F, above described. A pulley S is fast on the spreadershaft R', and a belt T connects this pulley with the one P on the reel-shaft O, as shown in full and dotted lines in Fig. 3.

In rear of the crosser-shafts the upper and lower sides of the loom-frame are provided with brackets U, set at au angle to a horizontal line and provided with bearings for grooved rollers V V', this construction and arrangement of parts serving as a means to cause the warp-wires of the fabric to draw evenly from spools W, loosely arranged on spindles X, that project from a wall Y at the rear of the loom-frame. Each spool-spindle has an ontturned tiange n at its inner end for impingement against the adjacent head of a spool, and the outer end of each spindle is squared to receive a collar w, that is held against the other spool-head by means of a spiral spring at, adjustable as to tension on the stem of a screw y, that has its bearing in said squared end of the spindle. By the means just described the spools are tensioned by their frictional contact with the flanges n and collars w on the spindles, whereby the wire on said spools is not unwound any faster than is necessary.

Arranged in front of the cross-braces M is a pressure-roller Z, that bears against the fabric and guides the same to the reel, the position of this pressure-roller being such that the draw of said fabric is always from the same center, regardless ot the amount accumulated on said reel.

In practice the warp-wires are carried from the spools XV around in grooves in the rollers V V', then between the crosser-shafts R R', then through the interstices e of the slat-carrier, then under the pressure-roller Z, and finally fastened to the reel Q. The number of the warp-wires may be Varied at will, and the distance apart of these wires is regulated by their position with relation to the grooves in the rollers V V. By the rotation of the shafts R R the crosser-arms 9' thereon act against the wires in such a manner that while some are raised the remainder are lowered at regular intervals to form the shed for a slat, the latter being placed in the receiver and carrier, as above described. rlhe receiver and carrier being thrown forward by the crankand-pitman mechanism above described, the slat is thus placed in the shed formed by the action of the crossers against the warp-wires and forced between the grippers N, after which said receiver and carrieris returned to its normal position. rlhe operation of weaving being continued, the wires are drawn off their spools by the action of the crossers, and as each slat is carried forward the fabric is forced on toward the reel Q and the belt T is just tight enough on the pulleys I S .as to cause said reel to partially rotate whenever there is slack in said fabric; otherwise this belt will slip on said pulleys.

In connection with the weaving mechanism above specified I may employ an automatic slat-feed, the one preferred being illustrated by Figs. S to 12,inclusive, and hereinafter described.

A feed-box A extends laterally from the upper side of the loom-frame adjacent to the opening g therein, and the outer end of this box is supported by a brace B', the latter being illustrated by full and dotted lines in Fig. 9. Extending up from the loom-frame parallel to the opening g therein is a wall C at a right angle to the rear wall of the feed-box A', and guards D connect the wall C with' the front wall of said feed-box, as best illustrated in Fig. S. The front wall of the feedbox is provided with horizontal slots b and horizontal guides c', the latter being arranged in pairs adjacent to the slots. Loosely arranged between each pair of the guides is a sliding block d', detachably retained in its working position by means of a screw c', passed through the adjacent slot b', and a washer f, arranged on the screw to bear against the inner side of the adjacent wall of the feed-box. Each of the blocks CZ has a hinged section cl2, provided with a finger g', that extends through the adjacent slot b' in the feed-box to bear against a bunch of slats arranged in said box to be successively fed to the reciprocating receiver and carrier above described, this construction and arrangement of parts being clearly illustrated in Figs. S and l0. A flexible device 71. is made fast to the upper one of the blocks d and runs over a pulley t" on the lower guide for the same, thence down over another pulley j', mounted on the lower one of said blocks, and then over still another pulley 7c', arranged on the lower guide for the latter block to connect with the weight E', as illustrated in Fig. 10.

The upper end of the inner side C of the slat receiver and carrier is vertically extended, as best illustrated in Fig. 12, and provided with right-angled brackets m, to which I attach spring-fingers fn, the latter passing the open inner end of the feed-box A as said slat receiver and carrieris reciprocated and being of such length as to come inside the guards D', as best illustrated in Fig. 8.

In practice the sections (Z2 of the sliding blocks d are swung back. on their hinges to bring the fingers g out of the feed-box, a bunch of slats placed in the latter, and said blocks run outward to raise the weight E', after which said hinged sections are swung back to bring their fingers in rear of said bunch of slats. The power of the weight E tends to run the blocks d forward toward the loom-frame, and thus the innermost slat iu the feed-box is held against the guards D in the path of the spring-fingers n on the extended upper end of the inner side of the IIO the bunch having been automatically fed to the receiver and carrier, as above described, the descent of the weight E causes said bunch f to move forward, and thus another slat is brought against the guards D', this operation being repeated as often as there are slats remaining in the feed-box.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
