SPECIFICATION forming part of Letters Patent No. 764,290, dated July 5, 1904.

Application filed October 16, 1901. Serial No. 78,791. (No model.)

To all whom it may concern:

Beit known that I, AZEL C. HOUG-H, residing at South Butler, in the county of Wayne and State'of New York, have invented certain new and useful Improvements in a Loom for Weaving Slat Blinds,- of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a loom for producing woven fabric for curtains, shades, screens, &c., which is formed of splints or slats of wood or other analogous material held to gether by heavy warpthreads interwoven therewith. Although looms have been designed intended iforsuch purposes, they. have not proved practical, nor have they come into commercial use, and fabrics of this class have generally been woven by handa slow, tedious, and expensive process. p

The object of-my invention is to provide an eflicient and practical machine which shall-be capable of producing such fabric in i a substantially automatic manner; and to this end my invention consists of the various features of construction, combinationsrof elements, and arrangement of parts, as will be clearly understood from the description hereinafter, taken in connection withthe accompanying drawings, and the novel features of which will be.pointed out in the claims at the end of this specification.

My invention is useful in Weaving any fabric the filling or weft of which is composed sition.

of substantially 'stifl' material, as slats, cane, or straw, in contradistinction from fabric the filling of which is of textile material proper,

In the accompanying drawings, Figure 1 is; a front elevation of my loom, portions being broken away, but enough being shown to give a clear general idea thereof. Fig. 2 is a side elevation. Fig. 3 is a vertical section, on an enlarged scale, on the line IV IV of Fig. 1, certain parts being omitted. Fig. 4: is a sec: tional detail of the upper end of parts shown in Fig. 3, showing the g'uide-lingei'sgancl the presser-finger thereof in a difi'erentipos Fig. 5 is a detail in end elevation, with the driving-shaft shown in section; showing the means by which the presser-fin ger shaft is actuated from the main drivingshaft. section, showing a cam on the prcsser-linger shaft which operates one of the guide-iinger shafts through an arm thereof, also showing the connection between the two parallel guidefinger shafts, through which such shafts act in unison. Fig. 7 is an enlarged side elevation of the shuttle shown in position on the raceway, one side of the raceway being broken away in order to show said shuttle. Fig. 8 is a bottom plan view of the same. Fig. 9 is an end elevation of the same. Fig. 10 is a detail showing the means.for operating the twister-heads. Fig. 11 is a bottom plan view' of plates attached to the lower side of the raceway which provide a track on which the shuttle runs. Fig. 12 is a sectional detail showing means for putting tension upon the warp-threads at-the point where they enter the upper end of the hollow twister-head arbor. Fig. 13 is a side elevation of the tensionguide.

Throughout the several views similar reference characters refer to similar parts.

My invention comprises generally means for feeding splints or slats into the shed of a loom, means for supplying warp threads or cords to form such shed and for twisting such warp-threads about each successive splint, means for beating up or forcing into proper position each successive splint as it is supplied by the shuttle, means for holding in alinement the splints as they are acted upon by the beatingup means, so as to prevent buckling, and various other subsidiary instrumentalities, as will be fully set forth hereinafter.

Referring to the drawings, the framework of the loom is composed of standards A A, cross-pieces a Z) c a, and various other supporting and stay pieces, as shown. It will i be. understood that the long pliable splints or strips which form the filling or weft of the fabric are supplied-to the loom by a shuttle which is thrown alternately from one end to the other of the raceway, preferably by springactuated pivoted levers or picker-sticks, a fresh splint being supplied to the shuttle at ;each end of the loom before it begins its move- Fig. 6 is an enlarged detail, partly in Leo ment along the raceway. Accordingly the shuttle and its operation will first be described in detail. It may be said in passing, however, that picker-sticks comprising levers 1 1, having at their upper ends yokes 2, adapted to encircle a projecting end of the shuttle, may be used to throw said shuttle from one end of the raceway to the other, such levers being pivoted at their lower ends at 3 3 to the lower cross-piece (Z. Spiral springs 44:, connected at one end to clips 5 5 on the pickersticks and at the other end to suitable abutments 6 6, tend to throw these picker-sticks forward normally in the position shown at the left-hand side of Fig. 1. When thrown back against the force of its spring, the pickerstick is adapted to be caught and held by a suitable latch, being thus detained until released through the agency of any suitable mechanism. Mechanism adapted to force back the picker-sticks against the resiliency of their springs must also be provided. A driving-shaft 7, supplied with power by a pulley and belt 8 or in any other desired way, is provided for the purpose of operating the picker-stick mechanism and various parts hereinafter described. This driving shaft has bearings in the lower ends of standards A.

The shuttle comprises a main frame-piece 7 O, which is preferably of wood for the sake of lightness and which has on its lower sides shoes 71, preferably of hardened steel, which are adapted to run upon tracks formed by the side pieces 72 of the lower plate of the raceway, (designated in a general way by 13,) which projects beneath the bars 73, which form the side walls of the raceway. The ends of the shuttle, as shown, comprise projections 74, which extend through the picker-stick loop, and the shuttle carries friction :rollers 75, against which the picker-sticks act. construction, however, is optional. The lower face of the shuttle carries spring jaws, retainers, or clips, into which asplint is adapted to be forced, as. shown at 7 6, wherein it is held by the spring-pressure in the passage of the shuttle through the raceway and until it is released therefrom, because of the projecting lower corner of the splint striking one.

of the lugs 77, which stands in its path, said lugs being located near the ends of the raceway. Each jaw of the shuttle is formed by a rigid abutment 78 and a member 79, which is spring-pressed toward the abutment. As shown, these spring pressed members are formed by the ends of a flexible steel strip fastened at 81 in the center of the shuttle and having such a curvature that their own elasticity will hold them normally against the fixed abutments 78. The ends of each of the jaw members 78 and 7 9are shaped so as to provide a funnel-shaped mouth for convenience of theoperator in inserting a splint.

the shuttle arrives at one end of the raceway, a'spl nt is inserted between the jaw at that twister-heads carry them all in unison. .upper end of the hollow arbor 90 is screwend of the shuttle by an operator just before the shuttle is thrown back by the operation of the picker-stick. A knob 82 may be formed on the top of the shuttle, so that the operator may grasp the knob in one hand to hold the shuttle firmly against the pickerstick and prevent rebounding while inserting the splint with the other hand. It will be seen that the holding-jaws on the shuttle are located in different vertical planes out of alinement with each other, and the lugs by which the splints are to be discharged are likewise out of alinement, as shown in Fig. 8. The precise position of these jaws and lugs is not essential. The cross-pieces 83, which carry the lugs 77, are positioned at any desired points along the raceway according to the length of the splints to be used and the width of the fabric'to be woven, so that the splints will be discharged at each end at the proper point; but the lugs recessed or grooved, as at 84:, so that in one positionthat is, the position at right angles to the racewaythe twister-head and the warpthreads will be located within such recesses and out of the way of the shuttle in its passage through the raceway. The precise form of these grooves is not essential; but they should be struck on a circle of large enough .diameter to provide free movement of the warp-threads as they are carried around by the twister-heads. the warp-threads and for interweaving them @about the splints will now. be described.

Such a i The means for supplying Spools 85 are supported in series on crosspieces 86, supported by brackets 87, carried by'the cross-pieces a, a suflicient number of spools being provided to supply each twister- ,head with the required number of warpthreads. Stays 88 and the standards A may carry rods 89, over which the warp passes. The twister-heads themselves are best shown .in Figs. 3 and 4 and comprise each a hollow threaded, as shown in Fig. 12, and an elongated guide 94 is adapted to screw down there- 'upon, which guide carries the screw-threaded A disk-shaped head 96, adjacent the.

pin 95. upper end of the arbor 90, is provided witha suitable sleeve which loosely encircles .the.

The.

v. ment is such as will beapparent from an in lower terminal of the pin 95, and said head is adapted to be forced down bya spiral spring 97 encircling the pin between the head and a nut 98 threaded tothe pin. The force of this spring can be adjusted by the nut 98. Two

warp-threads pass into the upper end of this arbor, one from a spool on each side'of the guide to prevent tangling, and tension is here put upon them, asindicated, in order that the feed thereof may be even and regular. then pass down through the hollow arbor through the eyes in the ends of the cross-head and down to the point where in the rotation of the twister-head they are woven around the splints, as clearly indicated in Figs. 3 and 4.

Oneof the hollow twister-hcad arbors carries a sleeve .99, fastened thereto by a setscrew or otherwise, as shown in Fig. 1. At

thelower end of this sleeve is the gear 93,

which forms one of the line of meshing gears across the loom by which the twister-heads are rotatedin unison. Above gear 93 upon andattached to-the same shaft 100 as is 93 is gear 101. Gear 101 is driven by segmental gear 102, which is formed upon one end of an arm pivoted at '103 on a stud supported by a bracket, (indicated by dotted lines in Fig. 10.) At the other end of this arm is pivoted a connecting-rod 104, the'other end of which is pivoted to crank-pin 105 upon a gear 106, This which has four dwells or stops thereon. gearis supported upon a stud projecting from the framework and is driven by a mutilated gear 107,:having teeth for a part only of its periphery. The construction and arrangespection ofFig. 10, that upon each revolution of thegear 107 the gear106 will be revolved through a quarter of its circumference and then stopped. The gear 107 is on the upper endof vertical shaft 108, journaled at it /t, Fig. 2, and carrying at its lower end a bevel-gear 109, which is driven by a bevel-gear 110 on the endof the driving-shaft 7 For the sake of clearness of illu'strationthe lower bearing It is not deemed necessary to show the bell in connection herewith; but it will be under stood that such construction will be advantageous when it is desired to feed a certain number of splints to the machine and then change tosplints of another color, as in weavingpatternswherein the color of the splints is to be changed at predetermined intervals.

At what I term the operating point that 3 is, the point where a fresh splint has just been supplied and the warp-threads are being twist- 1 ed therearoundI provide means for insuring an efficient action of the loom whereby a firmly-woven smooth fabric will be produced as follows: Three shafts itl 777/6Xi36l1d across the machine, being supported at their ends in suitable bearings in brackets 132, projecting from the standards A, which brackets also serve as supports for the ends of the raceway B. The two shafts Z: Z are in a position such that the fabric is fed down between them, and

they carry at such intervals as may be desired 7 parts 133, which I term guide-fingers, the shape of which is clearly shown in Fig. 1 as bored to encircle their shafts and having projecting fingers in the shape of a two-pronged fork. The third shaft m carries what I term presser-fingers, which alternate with the guide-fingers before mentioned and consist, as shown in Figs. 3 and 4,of a part a, adapted to be rigidly connected to the shaft m, and

"a second part 0, pivoted at q to said first-mentioned part and held to move therewith by a spring 19, which presses on the upper face of said pivoted part and is adjustably held thereto by nut 10 upon the end of a bolt 4, which passes through both parts. The end of part 0 is forked, so that it may pass upon each side of the warp-thread 1n operation, as is shown 5 in Fig. 4, which is a section taken through the center of the presser-fingers. The end of on the main shaft, which at every revoiution of the shaft strikes a friction-roller 136 on the arm 137, projecting from the lever 138,

; pivoted to the framework, and which is connected by link 139 to arm 140 on shaft 141, arm 142 projecting from which has pivoted thereto a hooked rod 143, to whichis connected a sprocket-chain 144, which passes over shaft m carries a sprocket 134, which is partially rotated to rock said shaft from a cam sprocket 134, and at the other end of which is a s piralrspring 145, fastened to afixcd abutment on the standard A. Thus by the force of the spring 145 the shaft m. isheld normally in the position shown in Fig. 3, whichis the inoperative position; but at each revolution i of the driving-shaft through the connections described the cam 135 rocks said shaft and 1 throws it forward, so that the presser-fingers rest upon andforce down the splint which has been last fed to the loom, thus beating up the splint and forcing it into the proper position relative to the part of the fabric already woven. As shown in Fig. 6, a cam 146 upon shaft on engages an arm 147, rigid with shaft Z. The two shafts k Z are connected together by a pin 148 upon an arm'projecting from one shaft, which is located within a recess or fork 149 of an arm projecting from the other: A spring 150, F ig; 2, connected to an arm 151 on the "other side of the shaft lt'fholds this shaft and the connected shaft Z normally in position, such that the guide-fingers carried thereby are in the position shown in Fig. 3. In this position said guide-fingers are open and a splint dropped from the shuttle will fall between the guide-fingers approximately adjacent the splint below it. Then during the revolution of shaft m, which is actuated from the driving-shaft at the proper time, the cam 146 on said shaft will first throw up the arm 147, (shown in Fig. 6,) and the guide-fingers will be thrown together to press or grip the splint loosely between them. It will of course be understood that when it is said that the guidefingers grip the splint to hold it under pressure it is only meant sufficient pressure to preserve its alinement and prevent it from buckling under the action of the presser-fingers. Such buckling will occur owing to the pliable nature of the splints unless they are supported in this way. However, the pressure of the guide-fingers must not be such as to interfere with the beating-up action now. to be described. Then upon a continued movement of the shaft m the presser-fingers 0 will be thrown down to force the splints into position, as already described, while the guide-fingers will prevent the long pliable splints from buckling beneath the force of the presser-fingers, supplying temporarily a stiffening to the splints, which is necessary in order that they may be beaten up into proper position.

From this description of parts and of the operation of various of these parts the general operation of the loom will be readily understood; but such operation will be briefly retraced.

Assuming that the parts stand as shown in Fig. 1 and that the revolution of the drivingshaft causes the right-hand latch to release the corresponding picker-stick, such picker-stick being free will be thrown by its spring, and the shuttle carrying a splint with which it has been supplied by an attendant will be shot or driven through the raceway B until it stops at the opposite end thereof. During the time when the shuttle is at rest and being supplied with fresh splints at either end of the machine the connections described will actuate the twister-heads so that the warp-threads which during the passage of the shuttle have been resting out of the way in the recesses of the raceway and of its bottom plan will now be carried around by the twister-heads to weave the warp-threads about the splint last fed. 1n the construction as described and shown in detail in Fig. 10 the operation of the mechanism will be to carry each twister-head half way around, then a rest, then half-way around farther, another rest, then half-way back and a rest, half-way back and another rest. The

effect of this motion will be to wind the warpthreads about the splints with an interlocking twist, as will be seen upon inspection of Fig. 4, although it will be obvious that the twister-heads might be simply rotated halfway around and then half-way back, whereby the warp-threads will be simply woven in and out between thesplints, but straight up and down without any interlocking or twisting of the threads themselves. Immediately after the splint is fed into position and while this twisting is going on the guide and presser fingers are actuated through the described mechanism to force the splint into the desired position and to hold it there Without buckling or getting out of alinement. As soon as the cam 135 has passed the. roller 136 the guide-fingers open out and the presserfingers are thrown back. At the same time the twister-heads have come to rest, so that the warp-threads are located out of the way of the shuttle. The raceway is then clear. The picker-stick on the right is then thrown back and the picker-stick on the left then released to throw the shuttle forward for supplying another splint, and the cycle is repeated. Suitable means may be provided for antomatically taking up the fabric as it is completed.

The various advantages which result from the use of constructions such asvI have described in weaving fabrics of this class will be apparent. It should be especially noted, however, that owing to the light pliable nature of the splints, because of which they tend to float in the air, it is advantageous to provide some means for carrying them in the shuttle and for taking them from the shuttle which shall be positive and shall not depend purely upon the force of gravity acting upon the splint when it is released from the jaws of a shuttle or carrier. My construction, wherein the splints are carried on the lower face of the shuttle and are released therefrom through the splint striking a fixed lug projecting into its path, provides a positive means for knocking out the splint at any desired point, and the splints from this point will fall directly in the shed of the warp in the desired position. Immediately after the splintis fed into position and while this twisting is going on the guide and presser fingers are actuated through the described mechanism to force the splint into the desired position and to hold it there without buckling or getting out of alinement. As soon as the cam 135 has passed the roller 136 the guide-fingers open out and the presserfingers are thrown back. At the same time the twister-heads have come to rest, so that the warp-threads are located out of the way of the shuttle, the raceway is then clear, the picker-finger on the left is then thrown back and the picker-finger on the right then released to throw the shuttle forward for supplying another splint, and the cycle is repeated. The operation by which the fabric as it is completed is automatically taken up by means of feed-rolls and the means by which a supple mental manual feed may be used as desired are suiiiciently clear from the description already given. 7

The various'advantages which result from the use of constructions such as I have de scribed in weaving fabrics of this class will be apparent." It should be especially noted, however, that owing to the light pliable nature of v the splints, because of which they tend to float in the air, it isadvantageous to provide some means for carrymg them in the shuttle and for taking them from the shuttle whlch shall be positive and shall not depend purely upon the force of gravity acting upon the splint when it is released from the jaws of a shuttle or carrier. My construction, wherein the splints are carried on. the lower face of the shuttle and are released therefrom through the splint striking a fixed lug projecting into its path, provides a positive means for knocking out the splint at any desired point, and the splints from this point will fall directly in the shed of the warp in the desired. position. It should also be noted that my construction of clutch is such that it" the loom is reversed the rod 40 will simply back away from pin 4-1 without reversing the clutch. It will be seen that the construction is such that it is impossible for an operator to do anything to the loom which will interrupt the cycle of opera tions through which the various parts pass,

but that whenever the loom is stopped it will always be in position to be started up with all the parts continuing the operation from the point at which they stopped. This prevents injury and breaking down which might otherwise occur in a loom a complete cycle oi' which depends upon the harmonious interworking of different parts.
