' A. J. WILLIAMS, Or UTIOA. NEW YORK- -Y Specification forming part ot" Letters Patent No. 6.701, dated September 11, 1849.

.To all whom. it may concern y v Be it known that I, ABIJAH J WILLIAMS, of the city of Utica, in zhe county of Oneida and State of New York, have invented a new and. useful Machine for Making Wire Heddles for vWeavers"Harness, whichis described as follows, reference being had to the annexed drawings ofthe same, making part of this specification. v Figure l is a perspective view ofthe 1nachine arran gedfor operation, showin g the right end and left side and top, the hooked receiving and discharging rod being'arranged preparatory to receiving the wire. Fig. 2 is a perspective view of the apparatus for folding, drawing, 'und twisting the wire into heddles and discharging the same when iinish'ed, detached frein the machine. Fig. 3 is avertical longitudinal section of two hollow twistingcylinders for twistingthe wires into heddles drawn full sige, as used in the modiiied form of the machine. Fig. et is a view of one-half of the same. Fig. 5 is aperspective view ofthe second drivin g-whecl, l, on the main shaft, with cogged segments on its sides, detached from 4the machine. 6 is a perspective view of the first driving-wheel, G, on the main shaft, with acogged segment on its periphery. Fig. 7 is aperspec'tive view of the modified form of the machine for twisting the wire into hcddles, being a pair of pinchers, a grooved cylinder and thimble, and propelling cog-v wheel. Fig. S is another modified form of machine for twisting the wire into heddles, being a cog-wheel and sliding tooth, which may be used instead ofthe vibrating teeth represented in Figs. Saud l0, the tooth sliding toward the center. Fig. 9 is au end view of the slid-.

in g thimble, showin g the transverse pin therein for operating the tooth when the spring is not used, as in Fig. 3. Fig. l() is a section showing the cylinder, teeth, springs, and cog-wheel detached from the frame. Figll is a view of thesliding thmble detached in like manner.v

ment consists Ain a certain new and useful combination and arrangement of mechanical devices by which a continuous-piece ofwire'is cut off from .the skein of wireo'n the reel as it is fed into the machine between rollers and seized by a hook at the middle of its length and doubled, or folded, while being drawn into the cylinders, where it is held tirinly'by pinchers and vibrating-teeth passing between thevr strands while the cylinders are made to revolve and twist the wires and form the heddles, and then cause the pinchcrs-,to open, withdraw the vibrating teeth, and discharge the heddles in a finished state, as representedl inFig. 14. The frame to contain and support the mechanism required to perform the .above-named operations should be made of suitable'size, strength, and material to containI and support the several parts hereinafter described. fil-wo revolving cylinders, a ai,ffo'r forming theheddles, are arranged upon the top of this frame,

',having their axes in a right line and parallel with the 'top ofthe frame, and turni'iig in suit able bearings or boxes, d. These cylinders-are made of any suitable metal and otany required diameter, length, and caliber for the reception of the drawing and discharging rod B, which is to move back and 'forth therein while drawing the wire and discharging the heddle. Each cylinder contains two grooves, cgtor the reccption ofthe vibra-tin g teeth t. One ofthe grooves extends from the left end of the cylinder as far as two-thirds its length, or according to the length of the` tooth to be placed therein, as seen in Fig. 10. The other groove (which is on the opposite side of the cylinder) extends from the right end town/ril the left end the same distance, and is made 'inthe same manner. Each groove is made ofthe required depth to receive the teeth. The portion of the groove through which the point of the tooth passes is made to extend from the -periphery tothe bore for the purpose of allowing the point of the tooth (when depressed by the thimble) to-pass between the strands of the wire. The-vibrating tooth, after being. placed in the groove, is hung by4 a pin,f, at oneend, connecting-it to the cylinder. A spring, g, Figs. VIQ-and 41 3, for throwing the tooth out from the heddle, lwhen iinished, is placed in the groove, and may be attached by one of its ends to the cylinder, or

internal diameter of the sliding thimble is equal tothe external diameter of the cylinder. The periphery is recessed or out through, asseen at u, to give room for the inclined plane t of the tooth next the cog-wheel to move outward from the centerv the required distance. A?

circular channel; or groove, A2, is formed on the outer surface ot' thethimblejto receive a fork, I, attached to a sliding rod, L, by which it (with theI thimble) is moved back and out from ,the cylinder; or the-tooth may -be forced between the wires and from them bythe sliding movement or action of the thimble by forming an inclined plane on the upper and under ed'es of the tooth, as vseen in Fig. 3, against which the thimblev acts vasv-it is moved to the right andto the left, Vthe inner surface of the thiiable acting against the outer inclined surihee ot' the, tooth a-nd a transverse pim-p2, il, ia.; the thimhle acting against the inner aeiined surface, the inclined portion ot the tooth passing betweenthe inner surface ot the thimbleand the said'l pin p2.

attached to the frame and bearing against the under side of the hinged guideQ. and held suitable gearing for giving it the required rol tary motion to twist the wire, as seen in Figs. v1, 2, 12.

'The second twisting-cylindei, with its viother appendages, being made in the same manner as'the cylinder and its appendages just described, it is also attached to the' sliding rod L in the samemanner by a fork, Z.

This sliding rod moves back and forth in corresponding opeuin gs in the standards or boxes supporting the cylinders. Itis operated by a combination of levers, m n, 'and a rod, u', aetuated by two pins, G G2, Figs. l and 13, projecting-from the face' ot' the wheel G, that strikes against a triangular block, M, fastened to one of the aforesaid levers-namely, that which is lettered m.'

One ot' these pinchcrs is arranged 'between the cylinders c a to hold the wires during the twisting operation to form the in its .required position by 'al1-od, s, attached to one'otpthe arms ot the said right-angled j lever and leading thence to a vibrating lever, g 0, which lever U is held in its required position bythe eircnlarpart ot the ram-wheel brating teeth, springs, sliding thimbles, and] middle eye of the iieddle through which the warp passes. The other pair of pinchers is arranged at the end of the cylinder at which the wire first enters for the purpose of helrlin g 'the two ends of the wire iirmly during the 5 l. The wire, being` eut ott' from the skein, is then dropped '(b)r the descent oi the hinged guide4 Q) onto the'hook ot' the feeding- A,and discharging rod B.A This is eii'ectcd by the rghtangled lever p* turning on its l'ulcrunx, caused by a notch, l, in the cam-wheel ll?, into whicha pin, g, projecting' from the lever t). enters as the said wheel l) revolves. A spring, q', or weight attached to the hinged guide Q, causes its'grooved edge containing thc-wire to drop and deliver the wire onto the hook B2. The Wire, having been dropped into the hook on the end of the feeding and discharging rod B, is next doubled together at the middle by being drawn into. the bores of thev This is done by eonnecttwisting-cyiinslers. ing the rod l; to a sliding rack, l), by aconmeeting-yoke, D', which causes the-rack and rod B to move simultaneously. The rack is drawn back, and with it the rod and wire, by means of a. cog-wheeh'E, thatrniatchcsfinto the ra el: l). This cog-wheel is fixedon a horizontal. shaft, "i, von. which there is apin'ion, F, operated by the cogged segment-wheelfG on the main shaft b.

connecting-rod x2, and pin 4 in wheel l. A drum, y, is placed on the axle or shaft lr of the cog-wheel E, which winds up a cord, z, as the vrack is drawn backf, to which cord a weighted lever or spring, S2, is attachedi'or throwing the discharging-rod into the cylinders, and thus throwin g outthe finished heddle.

cylinders, and the rack secured by the catch w, the thimbles A are then moved to the left, in the manner before described, by the coni bined action of thelslidinzg` rod L, levers on n, and connecting-rod n', actuated "y the pins G Gzin the wheel G, which forces the teeth between the strands of wire, as aforesaid. The pinchers K are closed upon the wire before the .twisting` commences. and after the wire is drawn into "thefcylinders a andthe feeding rollerscomme'nce to brii'lg' forwardthewire for another heddle, the hinged guide Q. bei ng previously raised to receive it. operation then commences, which is effected by meansvof-thesegnientwheel I on the main shaft I) turninga bevel-pinion, Ilz, on the shaft H,'on whichthere" is a cogavheel, H3, into which gears a cog-wheel, j, on one' of the cyln inders and an intermediate pinion, 2, into die beingsnliiciently twisted, the teeth 't and pinchers K are disengaged from the same in The rack is held back by a sp1-in catch, a', attached to the standard ir which `the rackslides, and actuated by a lever, w',

I do not claim making heddles of pieces of wire doubled around pins and twisted by machinery, as this has been heretolbre'patented; but

What I do claim as my invention, and desire to secure by Letters llatent, is

The before-described mode of making wire heddles from. a Kskein orhank of Wire by power machinery, by cutting' the wire as it is fed into the machine into suitablelengths to form, when doubled, the required heddles, and to drop said wires separately ontoA a horizontal reciprocating feeding' and discharging-hook! rod," by which each wire is 'doubled into two1 strands and drawn into the center of two revolving cylinders turning in contraryl directions, wherein the strands are held bypinchers and vibrating teeth forced between them until they are twisted into the form of therequired heddle, when the heddl-e is discharged from the cylinders by the reci procatory movement of the hook-rod, the movements ofthe several parts of the machine te. effect the aforesaid object being produced by av combination and arrangement ,of mechanism similar to that `herein described and represented, er any other which may be substantiallythe saine, and by which-analogous results are produced.`

In testimony whereof I have hereunto signed y.
