WARPING AND BEAMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 266,331, dated October 24, 1882. Application filed January 7, 1882. (l\*o model.)

To all whom it may concern Be it known that I, JAMES WALMSLEY, of Hopedale, county of WVorcester, State of Massachusetts, have invented an Improvement in Warping and Beaming Machines, of which the following description, in connection with the accompanying drawings, is a specification.

This invention is an improvement on the apparatus represented in my English Patent No. 3,779, dated November 20, 1873. In that patent the drop-wires, formed of flat metal wires, in practice about one-eighth of an inch wide, were bent over upon themselves in the direction of their thickness to form hooks, which resulted in making the hooked parts of the drop-wires wider than the drop-wire carriers, the hooks being so wide that the drop-wires could not be arranged compactly for use in beaming all sizes or numbers of yarns. The drop-wires and carriers as herein constructed and combined occupy equal spaces. The carriers hold the drop-wires, and the latter, of sheet metal, have their eyes formed by curving the carriers over in front in the direction of the width of the shank and lower part of the drop-wire below the carriers, so that the space in thickness occupied by the drop-wire does not exceed that occupied by the drop-wire carrier. With the drop-wire and carrier as herein combined it is possible to place a greater number of yarns on a warp-beam of a given length than could be done with drop-wires and carriers such as shown in my said patent, for as the hooks of the drop-wires are not thicker than their bodies or shanks, and it is possible to place a greater number of drop-wires in the same space, the thickness of the bodies of the drop-wires, and not the thickness of the hooks, determines the space to be occupied by each drop-wire. The drop-wire in my said patent had a shoulder where the hook and body parts of the wire joined, which necessitated frequent cleansing to keep it free from flyings, so that the drop-wire could operate as freely as desirable; but in this my present invention I have avoided the formation of such a shoulder and the consequent accumulation of flyings thereon, and the drop-wire is free to fall as soon as the yarn breaks. In my patent referred to all drop-wires unsupported by yarn were lifted automatically by a bar having inclines and operated upon at its ends by means of arms on an upright shaft of the beltshifting mechanism; but in this my present invention I have simplified the construction of the mechanism for so lifting the drop-wires, and have devised instead a vertically-movin g lifting-bar actuated by a weighted treadle, the weight being effective to operate the treadle and elevate the lifting-bar while the machine is being stopped to mend a broken yarn.

Figure 1 represents a front elevation of a warping and beaming machine embodying my invention; Fig. 2, a partial view of the lefthand end of the machine; Fig. 3, a partial vertical section on the dotted lineman, Fig. 1; Fig. 4, a detail referring to the driving-pulley; Fig. 5, an enlarged detail of the drop-Wire, its carrier, and the expanding springs which hold and space the said carriers and their dropwires. Fig. 6 is a cross-section on the line 9 y of Fig. 5; and Fig. 7 is a modification, to be referred to.

The frame-work A, of suitable shape to sustain the working parts, has bearings for the main driven shaft A, upon which is fixed the winding cylinder'or drum A upon which rests the warp-beam B, of usual construction. This shaft A, as herein shown, has splined upon it the hub to of the male part of a friction-clutch pulley, made as a cone, adapted to enter the female part a of the said friction-pulley, it being loose on the said shaft. The shaft A has at its opposite end a grooved cam, 0, which imparts two complete vibrations to the feelermoving lever l) at each rotation of the winding-drum A The yarn y to be wound upon the warp-beanr is passed between the drop-wire carriers 0, thence through the eyes at the upper ends, of the drop-wires 0 the shanks or bodies of which are held loosely by and guided in the guides c of the drop-wire carriers.

In operation the drop-wires, so long as the yarn is unbroken, will occupy the position Fig. 3, and as in dotted-line position,Fig. 5; but as soon as a yarn break the drop-wire held by it will drop into the full-line position, Fig. 5.

The legs ot'the drop-wire carrier are inserted betwten the coils of the usual expanding springs d (I, which in practice will be operated in any usual way-as, for instance, in Patent No. 221,799.

My improved drop-wires are stamped or cut from sheet metal, preferably from sheet-steel, by means of suitable dies, leaving them in the shape shown most elearlyin Fig. 5, the hooks thereof extending forward in the direction of the width of the drop-wires, and being of substantially the same thickness as the shanks or bodies of the drop'wires, a small open space, 2, beingleft forthe ready introduction of the yarn under the hooks. This construction of the drop-wire, it being very thin, enables me to insurea very compact arrangementofdrop-wires and get the greatest possible number in the least amount ofspace, which is a matter oivery considerableimportance to manufacturers. A yarn having been broken, the drop-wire will fall, as shown in full lines, Fig. 5, thus placing its lower end in line with the feeler e, which is composed of a long bar mounted upon arms 0 of a rod, 0 having another arm, 0 provided with a pivoted catch, K, substantially such as shown in my said patent. The rod (1 has at its other end an arm, 0, provided with a weight, 3, the normal tendency of the weight being to turn the feelertoward the carrier-box at, in front of which slide the drop-wires. 'lheieeler-aetuating lever 12, at each movement in thedirection of the arrow 5, Fig. 2, pushes against the catch K and rocks the rod 0 in its bearings, moving the feeler aback from the front of the box 4, and as the said lever Z) is moved in the opposite direction the weight 3 is made effcetive to turn the rod 0 so as to move the t'eeler toward the box 4 and strike the lower ends of any of the dropwires which may have been permitted to fall by reason of a broken yarn. Should a drop-wire have fallen, the forward movement of the fceler will be arrested by its contact with the said drop-wire, and the rod 0 will be prevented from turning farther in the direction of the arrow 6, and consequently the catch K, connected with the arm a of rod 0 (the catch then resting on a shoulder at the up per end of lever b, which lever at that time is being moy'cd in a direction opposite the arrow 5 in Fig. 2,) will drop from the said shoulder upon a pin, 8, projecting from the knocking-off lever g, having at one side of it a lag, 12,which is then engaged with the lower side of a notched plate, 71 secured to the frame-work.

This lug is kept pressed against the under side of the said plate by the weighted lever i and by gravity. \Vhen the catch K drops from the shoulder of the lever Z) upon the pin 8, as described, after the i'eeler has been stopped by the drop-wire, thefront edge of the lever b, at its next movement in the direction of the arrow 5,will strike the catch K, then lying between its front edge and the righthand side (see Fig. 2) of the knocking-off lever, and will push the knocking-011 lever far enough to the left to disengage its lug 12 from the notched plate, when the weighted lever 'i will immediately lift the knocking-olf lever and permitthe shaft Z, with which the said weighted lever is connected, to turn. This shaft 1 has connected with it two arms, Z P, the outer ends of which are made to carry a foot-board, l, thus making a treadle. The shaft I has upon it a pin, m, which enters a slot, 13, ot' a lever, m pivoted at 111-. This lever m is i'orkcd at one end to enter a groove in the hub a of the male part of the friction or clutch pulley device, and as it is moved in one or the other direction about its pivot or fulcrum 14 will separate or close the pulley parts to drive orleave the shaft-A at rest. This lever m has upon itastiti'spring, m, suitably held at one en d, and receiving against its other end the pin m, referred to, so that the said pin, acting on the spring to move the lever in a direction to engage the clutch or friction parts of the said pulley, will press them together and hold them together with a force depending upon the stiifness 0f the sprin This contrivance enables me to always secure a close iit, notwithstanding the wear of the parts, which fit would not be possible if the pin or acted directly against the lever m The lifting-bar 1;,which acts upon the lower end of and lifts any drop-wires which hzwe fallen by reason of broken yarns, is carried by rods f, jointed to the arms 1* of the treadle contrivance referred to. As the shaft 1 is turned to unelutch the friction-pulleys and stop the machine, the rods 12 are lifted, thus elevating the lifting-bar, as described, the end of the iit'tingbar being guided in suitable slots of the side frames.

The rod 0 is braced or supported at its center by the brace 0", having two hubs (see Fig. i) to embrace the said rod and the rod B,whieh supports the arms B, that hold the usual warpbeam, B.

The heads ot'the warp-beam have been omitted from the drawings to avoid confusion.

The yarn-supporting roller 13 is common to other beaming-machines.

Instead of attaching the guides c to the drop-wire carriers, they may, it is obvious, be attached to the guide and slide up and down on the carriers, as shown in Fig. 6.

I am aware of the drop-wire shown in United Patent No. 213,608; but such drop-wire diili'ers materially from the one shown by me. The

drop-wire shown in the said patent has its hooked part formed by bending the material over in the direction of its thickness instead of its width, as shown and claimed by me, and the patented drop-wire cannot be arranged as compactly as required, and as especially pro vided for by this my invention. The patented drop-wire is twisted upon itself above the carrier, which is not the case in my invention.

I claim-- 1. The straight drop-wirc having the hook at its end extendcdin thedirection of the width of the body of the drop wire below the drop wire carrier, combined with the drop-Wire carrier, with which the drop-wire is loosely connected,\vhereby the hook of the drop-wire and the carrier are enabled to occupy substantially the same extent of space in the direction of the thickness of the carrier, substantially as set forth.

2. The box 4: and its drop-Wire carriers and connected drop-wires, and the shaft 1, and its arms I? and means to move them, combined with the lifting-bar for the drop-wires, and rod 12 to elevate the lifting-bar vertically and lift the drop-wires, all substantially as described.

3. The fast and loose parts of the friction or clutch pulley and the lever m and its spring 15 Z, and means to operate said shaft, substantially as described.

In testimony whereofl have signed my name 20 to this specification in the presence of two subscribing witnesses.
