At the-end G of upper portion offrame-workal'e' located twohohhins, II, one, each-side of the centra-l -linc of the =mael|ine-,'sa id bohhins I'D-being suspended on horizontal spindles and containing the yarns-fi'om which harness is to he made. 'lhesie yarns are passed from the. bobbins ll down through rings arranged playircelyon vertical guide-rods, J, and from thence through fixed guide-eyes K to and-through eye's L in up per end of angular arm M. This arm M is attached to a transverse horizontal shaft. Y. and it carries the forked lever g for holding the beddle-eye deposited on stationary needle. From the' arm 1): the yarns are continued toward the end 0 of frame-work A. down'aronnd a grooved mlley P, into and along the groove Q of aneedle, t,-to the end 'S of same, passing out therefrom, the one yarn through an eye, a, on one side of the needle, and the other yarn from a similar eye, to, directly opposite on the other side of needle, and thence to the rig-ban ds, to which their ends are fastened, said rig-bands being extended along the length of the frame-work A from bobbins U topostsW as will be hereinafter described.- The needle It is made stationary, and is arranged along the length. of the machine, extending from about the loca-tionof the guide-pulley P to and below the shaftN of angular arm M, and beyond said arm toward the end of the machine where heddle-yarn bobbins H are located. W, the twister'of the machine. This twister is located in the machine at one side of the stationary needle R, and is, at the end of shaft X, in nearly the same horizontal plane as the needle but at right angles thereto, turning in suitable bearings of frame-work A. Y, a pinion-wheel,"

secured to twister-spindle X. Vith-pinion Y a gear-wheel, Z, interlocks, carrying on its shaft Afa pinion-wheel, B interlocking with a vertical toothed racked bar, 0 This rack-bar embraces the horizontal transverse shaft E,'by which I shaft and the arm 1) of frame-work B said rackbar is guided in its movementup and down, produced in the one case by the rex'olution of the cam E fixed to said primary shaft E, and in the other bythe spiral spring F This arrangement of mechanism, it is obvious, imparts a reciproeating rotary movement to the twister-shaft X. G a vertical shaft arranged just beyond needle It, with its axis in same vertical plane as the center line of needle B; This shaft G2 terminates below the plane of the needle R, turning in bearings of the frame-work 13. Its upper end is fork-shaped, and each tine has a similar arm, I), the two being parallel and projecting horizontally. The arms I; in their width and distance apart are equal to the full size of the. heddle-eye to be made. This construction of shaft G just above described, is particularlyshown by Fig. 6, plate 4. The said shaftG at its lower end has a monk-arm, I-I, connected through a stud with a --Blotted slide, I. This slide 1* moves in suitable guides of the frame-work B,and by a cam, J, of primary shaft F and spiral spring K, it is operated from time to time, imparting a reciprocating rotary movement to the shaft. This shaft G, with its armsl), constitutes what was previ-,

ously termed in this description the heddlc-eye former, and for convenience will be hereinafter so denominated. T, extension to slide 1 through which it bears on cam J to be operated thereby, as described; Ir", a fork-shaped bar, shown in detailsinl ig. 7, plate .4. This bar is arranged in a correspondimgplane to the needle, just-beyond the heddleeye former G, so that when 0 1-.

era-ted it will pass between the uprightarms of heddlc-eye former. The extremcendsf of tines For mov-" to bar U are made as shown in Fig. 7. ing bar U to and fro between the arms of the heddle-eye former (it being suitably guided) the upper end of a vertieallever, M, is hung to it, which, extending below, is confined to the peripheryof a cam, N, on primary shaft F, made of suitable shape to-move the said bar U forward, and to allow it, bythe action of spiral spring 0', to be drawn back to its original place. This slide-bar L is the pusher, heretofore so called in this (lGSUllDt-lOIL- P l, fork-shaped levers, two

in number, and constructed with a hook, c, at

the end of their tines. These levers l are located one upon each side of the needle, and at their lower ends are hung to levers QF, pivoted by their end It to the frame-work at S, and by their end '1. are connected with the lower end of vertical pii m'en-rodliU that at their upper ends are pivoted to levers in turn pivoted to the frame-work at W. The levers V carry friction-- bowls bearing on cams X of the shaft Y, and actuating the lovers V. This shaft Y receives motion from the primary shaft F, to which in each case they are connected by bevel-gear wheels Z. The shafts'Y; iuaddition to their connection with the fork-levers P, above described, are also connected thereto through crank-arms A and short pitmen-rods B The said vertical levers P are what in thenature of this invention were called carriers for carrying the heddle-yarns to the rig-bands, and hereinafter will'be so designated for convenience of reference. 0 represents two fingers, arranged one on each side of the stationary needle 1t, betweeuthe tines of yarn-carriers P below the stationarypeedle-R, terminating at their lower end with horizontal arms D", projecting the one toward and beyond the other, and at-such endshung to a vertical piece, E. This piece E is arranged to slide up:

and down in the frame-work of the machine, and to be actuated by a cam, M on shaft E. F, studs of the yarn-carriers P, to act on the fingers 0 to open them from the needle, as will be hereafter described. G arms, two in number, one at each rig-band, and outside thereof. These arms Gr are located. transversely of the machine, and directly opposite each other. Their inner ends are hook-shaped, and by the outer ends of each they are fastenedto short horizontal longitudinal shafts l1, having arms 1? .arra-n ged to bear upon the cam-edges J of the cylinders K, said cylinders turning within upright brackets L at the top of frame-work. These cylinders are driven as will be hereinafter described. The arms G? are for the purpose of receivin g the yarns from the yam-carriers P, and to hold them while the knitting-needles are operating, as will be presently described. For convenience of description they will be designated as the heddle-yarn holders. M are barbed knitting-needles of the ordinary construction, one at and along the outside of each rig-band. Ilhese needles M are socnred to a common horizontal cross-head, N

suitably guided, Q? and P arms on rockshaft .into position.

A. N, and thearm 'P bears ona cam, Q, of the primaryshaft E, causing a movement of the cross-head N in the one direction, and a spring,

It, a movement in the opposite direction. Theknitting-needles M move throughguide and supportingeeyes of fixed horizontal armsS". Against the outerend of these-guide-arms S presser-rollers U of arms V bear, conforming the-rig-bands thereto. The arms V are secured to brackets L by' adjustable connect-ions. The end J of needle-support and guides S acts to knock ofl the stitches from the needles and spring-arms J J to press the needle-barbs down in the grooves of --the needles when it is required to slip the loop oii' said needles.

The cylinders K hereinbefore referred to are hollow. from end to end, and the rig-bandsfrom their bobbins are passed through them to the pins V. Said cylinders are arranged to rotate through gear-wheels W X and X connecting them,with" shaft Y, geared with the primary shaft F, as herein before described, The cylinders each carry a bobbin, Y having yarn wound upon it. These yarns are conducted through the cylinders K to and through a guide-eye, Z fixed to the cylinders K thence to therig-bands, to which they are fastened at the same point as the heddle-yarns.

'from the driving-shaft D through the series of gear-wheels F arranged along and upon one side of the machine,

.The fork-lever and retainerg for heddle-eye, as before stated, is carried by the angular arm M, to which, at itsend 13?, it .is jointed. This fork-lever g is also connected to one end of a link, OF, hung: loosely by its other end upon a transverse horizontal shaft, 1), below. the shaft N. the shaft D 'bein'g arranged to turn in suitable bearings of the frame-work. To the shaft N is secured a lever, B, projecting downward into position to be acted upon by a cam, F, of the primary shaft E. By this cam F the shaft)? is moved in one'direction, while by a spiral spring, G9, connected to the lever E it is moved in op-' posite directions. 'The movement of the fork-- is upward, and out of position about the heddle-eye on neelever g, by the operation of the cam dle, and by the spiral spring (i downward and 3y the link U the movement of ibrkcd-lever g in,and out of position with respect to the hcddleeye on needle It is more direct and straight, obviating all possibility of abrasion of the hcddlc-yarns. The forked-lever g, in addition to holding the heddle-eye, at the same time i also holds the needle It from lateral play, releasing-the needle, however, \\'l i.cn-itriscs, ,so as to -illlow the harness, as made, to pass along the h-i'igf-Ti of some.

' in addition to thchold on the needle R by-thc The arm 0 is connected to the cross-head.

forked-lever g, as above, described, a presser-foot, H is arranged, also for the same purpose. This presser-foot Hiis' formed so as to embrace the the sides of the needle R, and is fastened to the shaft 1)", hereinbefore referred to. This shaft D is provided with a fixed lever-arm, I, extended to bear upon a cam, J, of the primary shaft E. By this-cam J said resser-foot is operated in the one direction, and by a spiral spring, K connected with lever. I, in the other direction. The plane of action of the -presser-foot H is just back of that of the heddle-eye holder and it holds the needle R from lateral play when the said fork-lever g is released. The two, however, itis obvious, are "to operate the one after the other in such manner as not to interfere-with the progress of the harness through the machine by the feed of the carriage A. With the carriage A moved to a position near the main frame B, the rig-band-c'ords drawn off their bobbins. U under guide-pulleys G and thence to posts V, as described, weights H bein g suspended to keep the rig-bands at a tension, the heddle-yarns drawn and extended to the rigbands, and there fastened, as previously set forth, the yarn from lapper-bobbins properly drawn and fastened to the rig bands, the operation of the within-described machine, power being applied to the driving-shaft I), is as follows: The yarn from one eye of the needle is seized by the twister WV on such side, carrying it downward completely around the horizontalprojectiu g arms b of heddleeye former G said former having been previously turned to bring said arms to,

point in the proper direction therefor. The heddle-eye former is, then turned back, bringing its arms b in line with the stationary needle R, the twister turning back to allow the yarn to pass off of it, where, the former remaining stationary, the heddle-yarn wound around its arms I) is then pushed by the pins L from said arms onto the needle R, and along its length beyond its eyes, drawing, as a consequence, the. yarns leading from such eyes along with it. The fork-lever g is now moved down, bringing its tines outside of but against the looped yarn or heddle-eye about the needle, holding it there, while on each side of the needle R the yarns stretching from ends of looped yarn to needle-eyes are taken by the vertical fingers C", pulled out from the needle toward the rig-band, and deposited on'the hook ends of the carriers P, by which the two yarns are then carried to and beyond the rig-bands and deposited upon the yarn-holders Gr, there arranged for the knitting-needles to take hold of them. VVit-h the heddleyarns thus held, and the yarn from each of the lapper-cylinders through their continuous rotary movement lapped or wound around the barbed needles and the rigband cords, theheddle-yarns are taken by the needles in their forward movement the yarnholders then dropping away from theyarn, when the needles move baclnvard and close againstthe prcssers in the usual manner pf @tting, completing thus the last of the several stagesof. the operations of the machine. The movements thus described take place for each and every hed dle-(. -yeinadein the machine, and during the same the carria e or cross-head A is slowl carried or fed forward, so as to take the heddleeye as formed sufficiently forward for another hcd-dleeye to be made. v

In the operation of. the several devices which act dircctlynpon the lm-rness-yan1s, as above described, the gearing or other means employed between a continuous moving driving-shaft must be arranged, and constructed to impart the motions necessary and at the proper time or times.

The particular movement of the several parts isas follows The twister is reciprocating rotary, moving sufiiciently around in the one direction to secure the disposition of the heddle-yarn seized by it upon the heddle-eye former, and then back to allow the yarn to pass oif of it and to again take a heddle-ya-rn and twist'itaround the former tor the next heddle-eye. The former G is reciprocating rotary, but only through a portion of a circle-aquarter bein g surficient'its plane of rotation and that of the twister being at right angles to each other, and the needle. R being disposed as described. The heddle-eye retainer or lever g is intermittent rocking, moving down into and up out of the position stated, its movement downward occurring just after the deposit of heddle'eye on stationary needle 1%. by, pusher L and its movement upward releasing the heddleeye just after the stitching of the heddle-yarns to the rig-bands is completed. pusher is rectilinear intermittent. The vertical fingers (J and hcddle-yarn carriers 1 have each both an upward movementand a movement toward the rig'bands. The movement of the fingers 0 toward the rig-bands is only for a portion of the distance, while that of the yarn-carriers P? is for the entire distance and beyond the rigbands, and they operate together as follows: The fingers first move, being acted on through their common holder E" by cam M to shaft E, and are raised, passing through the cone-aves m of needles R, between needle and heddle-yarns' stretched along it. In Fig. 4, plate 4, they are shown intheir highest positionyand then the yarn-carriers 1, they each moving both upward and toward and beyond the rig-bands, eauseat the same time a partial outward movement of the fingers G from the 'i'ieedle.

duced by the cam X and crank-arm B of shaft Yoperatin g conjointly through the arrangement of parts hereinbci'ore described, as disposed between said cam X and crank-arm 1 The outward movement of the fingers U" is produced by the impingement of the studs F of yarn-carriers against the angular arm 1) of such fingers, swinging necessarily such fingers outward, the yarncarriers on'one side of the needle swinging out the finger on the other or opposite side. By the continued movement toward the rig-bands of the. yarn-carriers their studs F escape or pass by the ends of finger-arms l), allmving the fingers to be thrown back to their position against thence dle by the action of bent springs a properly ap- The heddle eye The upward and outward movements of the yarn-carriers are proplied therefor, while, at the same time, from their weight and that of their common carrier or slide E, they drop into position to be a-gain raised.

1 u I l a" Betore the fingers have reached the hunt of their outward movement the hook ends of yarn-car riers have reached a position, both as to height and distance from needle, to take on their hooks the yarns drawn out from needle by the fingers,

and before such fingers fiy-backto the needle.

The yarn-carriers continue to carry the yarns to the rig-bands, as before described, depositing them on the yarn-holders G there arranged, the yarn-carriers having a downward movement for so depositing their yarns on the holders.

The movement of the yarnholders is vertical rocking, and their upward movement occurs in time to take the yarns from the yarn-carriers,

drawing them up partially around the outside of rig-bands and knittin g-needles, where, remaining stationary, the lmitting-needles then are moved toward the delivery end 0 of the machine, seizing the yarns looped on said yarn-holders, which then. lower, releasing the heddle-yarns for the knitting mechanism to complete the fastening to the rig-bands.

The movement of the forked lever g for holding heddle-eye in shape on, stationary. needle, whilethc yarn-carriers are conveying the heddleyarn to the rig-bands, is vertical rocking. p The concavities m of the needle 1% allow the, fingers 0 when raised as described, to pass more freely between the heddle-yarns and needle. By

the groove of the needle 1% the heddle-yarnspassing to the heddle-eye are removed from rubbing against the heddle-eyes, being fed along. the nee-. dle to the delivery end of the machine.

Having thus described my invention, 1 shall state my claim as follows:

1'. The combinat'on, with the twister W, of the means, substantially as described, for operating the same, as and for, the purpose specified.

2. The combination of the yarn-holders G with the yarucarriers P and barbed needles M, substantially as and for the purposes described.

3. The combination of the lappercylinders K ha ing guide-eyes, as described, with the yarnholders G" and needles M substantially as and for the purpose specified. I

4; The combination, with the needle-guide and support S of the presser-Wheels U when an ranged and operating as and for the purpose dc scribed. v

5. The combination, with the devices for formin g heddle-eyes, substantially -as described, of the devices for knitting the l'leddle-yarns to the rig-bands, substantially as and for the purpose described.

The above specification of my improvements in machines for making loom-harness signed by me this 3th day of March, 1871.
