Qriginal application filed December 17, 1921, Serial No. 523,140. Divided and this application led January 15, 1923.
This invention relates to improvements in looms and is a division from my former application, Serial No. 523,140, filed Deccmber 17, 1921.
The primary object of the invention is to provide a double loom in Iwhich the lays move in opposite directions and are connected together and mounted in such a manner as to balance one another, thereby to effect a -considerable saving in the amount of power required to operate the loom as compared with the operation of two single looms or a double loom having two similarly moving lays.
A further object of the invention is to provide a loom of simple, durable construc-4 tion, containing fewer parts and occupying smaller space as compared with ordinary looms of the same production capacity.
Another object is to providein a loomof this character an improved and simplified method of mounting. picker sticks. i
A still further object is tof provide for long picker sticks, thereby to-reduce the arcuate movement of the tips thereof and also to obtain a high speed of movement without increasing the movement of the picker staffs beyond that in general use.
In accordance with this invention there is provided a rigid frame comprising a pair of parallel lays connected at-their ends by swords, which swords are pivotally mounted intermediate their ends on the loom frame. A single crank shaft connected by pitman rods to the corresponding 'ends ofthe two swords will serve to oscillate the swords about their pivotal points and cause the two 'lays to beat in .oppositedirections TheV single crank shaft is provided with a single driving and controlling means.l The picker Sticks are mounted on the lay frame s o as to move with the lays in the well known manner, the sticks pertaining to one lay being anchored or secured to the other lay and extending across the frame, thereby to obtain the maximum possible length ofstick and assist in reducing the arcuate movement of the end thereof.
In the drawings which illustrate they invention;
Fig. 1 is an end .elevation of a loom constructed according to this invention, only those parts necessary to an understanding of the invention being shown.
Serial No. 612,810;
wise extending from end to end of-the loom and supported, preferablyvrotatably, in bearings 15 on the ends of, the, loom. A pair of double-ended swords 16 are mounted intermediate their ends on the shaft 14 and are each connected at one end to the crank f shaft by apitman rod 17. The'swords are preferably iXedly mounted o-n the shaft 14 so thatv when oscillated'by the pitmen they will impart oscillatory movement to the shaft for the purpose of operating other parts of the loom, such as take up mecha nism, (not shown). It willbe understood,
however, that the shaft 14 may be iXedlyV mounted in the end frames-and the swords rotatable thereon.` A pair of lay beams 18V disposed preferably vparallel `with one another and with lthe shaft 14 are rigidly con-k nected to corresponding` ends of the swords so as to form with the swords a rigid rectangular frame. VEach' lay 'beam is of any usual or suitable construction and carries reeds 1,9, and at the ends thereof shuttle boxes 2O and otherfusual or necessary app'urtenances.V Preferably the lay beams are disposed equidistantly on opposite sides of the shaft 14 but thisjis not essential.
In the ordinary loom in which the lay beats in av substantially horizontal direction the shuttle runs on the lay beam and the reedl is disposed in a substantially vertical plane at theback of the beam, the Warp passing in a substantially horizontal plane through the reed. For various reasons it is preferred in the present construction to pass the warps in substantially vertical directions and to so mount the swords and lays that the beatI is in substantially vertical direction. This necessitates the location of the reeds in substantially horizontal planes so that the shuttles run on the reeds rather than on the beams. With this disposition and movement of the lays the swords are inclined first one direction to the horizontal and then in the opposite direction, as will be readily seen from Figure l. n account of' this oscillation to produce the lay movement it is necessary to dispose the reeds. at an angle to the longitudinal axes of the swords, so that when the sword is at its maximum inclination in either direction the reed that is lowermost will not be inclined away from the centre of the loom but will be at least horizontal or,y preferably, inclined slightly downward.' toward the centre of the loom in order that. there may be no tendency for a shuttle to slide oil" the side of the reed and break the warp.. A Slight inolinat-on ofthe reedsA downwardlytoward the centre ofthe loom when their lowermost position so as to cause the Shuttles to hug the lay beams, is the referred disposition. The outer surfaces of t 'ie lay beams are naturally normal tothe planes of the reeds they carry and the lays can therefore be said to be inclined inwardly to converge toward a line above theloom. The angular rela tion of the reeds and the inclination of the lay beams to the longitudinal axes of the swords will be clearly seen in Figure l. lt will be ulld'erstood,` however, that while the substantially horizontal disposition of the lay traine i'el p1:eferred,I that the u ivention is not thus limited'. but that the. frame may be disposed, to locate the lays one. above the other so as to beat in siibstantially horizontal planes.
Eaehlay carries at. the baek ot its shuttle boxesr a braeket which serves asa guide for the picker stick operating i'n` that, shuttle box and serves also'for the anchorage of the picker stek operating in the Corresponding box of the other V rlhe picker sticks, designated 22t extendl V1C-roes the. Cent-re of lay 'oscillation'making it possible to employ a tous, Stick Without positioning, the. laye so tar apart as to make the machine. of' un'oommeroial Size., This disposition ot the. picker. Sticks therefore enables the laps to be brought. So @lose together toma te a very Compact machine. The Sticks are anchored to the brackets in any suitable or usual manner and provided. with. the, usual rotting. Shoes 23 bearing on the braekets and; serving to reduce;v or eliminate arcuate move mento'f the stick ends in order that the pickersQt thereon may travel in the straight line of the shuttle boites, In a double loom the distance between the lays will usually be such that it is possible to employ longery sticks, than in anordinary loom,s thus pro.- viding for greater travel and velocity of the pickers without increasing the movement of l the picker stalls.I rlhis question of picker travel and speed is, however, largely a matter of' the'position of the lug straps 25. on the picker sticks and the positioning of the picker staffs andthe design of' the cams,
but it is. well to note that the design of the lay frame enables these advantages of picker movement to be attained.
The picker sticks receive motion through the lugl straps 25, from picker stads 2G disposed vertically one on each side of the shaft le. and pivotally supported at their lower ends on brackets 27 carried by the end frames. ln Figure 2, while the bracket and picker staffs have been shown at only one end of the loom, it will be understood that the arrangement is duplicated at the opposite end. The, picker staffs receive motion from roller cams 28 mounted on a shaft 29 operatively connected with the driving train of the crank shaft and disposed beneath the shaft lll. At either end of the loom there are two vertically disposed picker staffs, one for each of the picker sticks, disposed at opposite sides of the axis of lay frame oscillation and operated by a single roller cam 28. This, location of the picker staffs close to the axis of lay oscillation enables the lug straps to be connected to the picker sticks at points. where the oscillatory movement is very little.l and thereby reduces the side draft on the picker sticks to a negligible amount.
ln the double vertical loom illustrated the harness, motion, designated 3.0, is disposed preferably below the'lays, as indicated in Figure l,whic h figure also indicates the position of the warp beams 3l, whip rolls 32 sand rolls 33' and cloth rolls 34 and the warp. 35 relative to the lays.
From the foregoing description it will be observed that there is provided to operate in a single machine a balanced lay frame embodying two oppositely movable lays and swords common 'to both lays, the whole forming a rigid framework oscillatable about a line intermediate the lays, and which framework carries the picker sticks anchored on the opposite side of the centre of oscillation from the lays to which they pertain. ln addition to reducing the number of parts this arrangement provides for a perfect bal ancing ofthe lays, so that a considerable` economy of power may be. effected as compared' with two single looms having in com` bination a capacity equal to the present double loom. The arrangement of the picker sticks has the advantage additional toy those alreadyl enumerated, thatvv the lug straps may be connected' to the 'sticks at points close to. the centre, of oscillation where the relative lateral movement of the. picker sticks and picker staffs will be very little, thereby greatly reducing the side draft on the picker sticks as compared with ordinary looms.
