SPECIFICATION forming'part of Letters Patent No.'4=26,4r73, dated April 29, 1890.

Application filed January 28, 1886. Serial No. 190,040. (No model.)

To aZZ whom it may concern.-

Be it known that I, BAsIL SAN-ER, a citizen of the United States, residing at Paterson, Passaic county, State of New Jersey, have invented a new and useful Improvement in Machines for Making Loom-Harness, of which the following is a specification, reference be ing had to the accompanyin drawings, forming a part thereof. a

A represents a machine for making loomharness, having the usual supporting-frame A, on and to which frame are arranged and secured various devices, which will be here inafter explained and claimed.

Figure 1 of the drawings shows one side of the machine in elevation. Fig. 2 shows in elevation the opposite side of the machine, (certain parts of the machine.) Fig. 3 is a plan of the machine, certain parts being omitted. Fig. 4: is a front elevation of the same, the

rods (0 and a hereinafter described, being shown in section. Fig. 5 is a rear elevation of the same, in which figure the bobbins and shaft are partly removed. Figs. 6 to 12, inclusive, show the effects produced by the de vices in their different movements when forming the harness. Fig. 13 is a detail view of a portion of one combination of devices.

Fig. 14 is a detached View of the sliding gear 0* and a portion of the supporting-shaft thereof, hereinafter described. Figs. 15 and 16 are detached views of cams on shaft a Figs. 17 and 18 are views of cams on shaft Z) to operate the swinging needles. Figs. 19 and 20 are views of inside cams on shaft 1'). Fig. 21 is a longitudinal section through the shut tle; and Fig. 22 is a cross-section through the same, the shuttle-carrier, and the adjacent eo-operating parts.

In suitable bearings arranged in the lower part of the frame A is jonrnaled a transverse driving-shaft 61-, having on one end of the same fast and loose pulleys a a On the opposite end of the said shaft is fixed a gear-wheel a and near the middle of its length said shaft has fixed thereon a bevel gear wheel a )Vheel 0. gears with a like wheel a, that is integral with a worm a, the said wheel a and worm a being j ournaled on a stud n' secured in the frame A. \Vorm a engages a worm-wheel a on one end of a shaft to journaled in braeket bearings a a and carrying a cam h, a double cam a, bevel gear-wheel a and a crank-arm a. The stud a" on the said crank-arm has eonn ected thereto one end of a link a, (see Fig. 4,).the opposite end of which is connected to a pawl-arm a, pivoted upon a stud e secured in a depending. portion of frame A, said arm carrying a pawl a and a spring a, which act against the pawl to press it into engagement with the teeth of a ratchet-wheel a, mounted upon the stud (L23. A retaining-pawl a provided on pin a holds ratchet-wheel (5 from back movement.

Connected with the ratchet-wheel a is'a wheel n gearing with a pinion a fixed ona rod a, journaled at one end in frame A and at the other in plate (Z On each side of .rod o is a guide-rod a each secured at one end to frame A and at the other to the plate a. On the rods a a is placed a bar or frame a having in the midd[e of the same. a split nut to engage with the threaded portion of the rod c4 Near the ends of frame or bar a are pins f to which are attached the ends On one end of a transversely arranged.

shaft Z) (see Fig. 4) is a bevel gear-wheel b, meshing with wheel a on shaft a Said shaft 6 has mounted thereon the cams D 11 e, and c. y

()n the front bottom plate B, secured to the frame, are placed hollow standards 1) I), (see Fig. 4,) in which are received the depending stems Zr of slotted horizontal sleeves 12' 13 Passing through the said sleeves are rods 12 5 (see Figs. 1 and 2,) the inner or left-hand ends of which in Fig. 1 (right-hand ends in Fig. 2) carry fingers b Z7 and the outer or right-hand ends of which in Fig. 1 (left-hand ends in Fig. 2) are slotted. Across the slot in each rod extends a pin, which is received in a slot at the upper end of a vertical lever o or D Levers Z) b are fulcrumed on pins b secured in curved brackets b, se

curedto plate B, and are connected at their lower ends to slides b arranged in guides Z1 upon the plate B and carrying projections b ,.which,if desired, may be slotted as shown in Fig. 2, and adjustably held to the slides by screws 17, said projections being disposed in position to be engaged by the projections of the cams 19 .0 on the shaft 1).

On plate B, nearthe middle of the machine, is a lug e, to which are pivoted levers e 6 extending in opposite directions toward the sides of the machine, said levers beingformed with projections, as shown, adapted to be engaged by the cams e 6 upon shaft 1) to depress the same, and being pressed upward by the spring S beneath the same.

On the free ends of the levers ee are pivoted the swinging needles e e. Needle e is connected by a rod 6 to a lever e, which is arranged to engage the part kg of the cam (L15 on shaft a, and a spring 6 connected at one end to the machine-frame and at the other to the needle 6 serves to move the latter in opposition to the cam. Needle e is connected by a rod 6 to the lever 6 which is acted upon by the part h of cam (L15 and moved in opposition to the cam by spring 6 attached at one end to the needle and at the otherto the machine-frame.

The two parts It 71 composing cam a are shown, respectively, in Figs. 15 and 16.

The vertical transverse plate a is secured to the machine-frame in an inclined or oblique position and is formed with two sets of slots,

each set comprising three slots 1., 2, and 3. The slots 3 and 2 respectively. serve for the reception and guidance of the shuttle-holders c and shuttle-operating slide-frames c 0 Each shuttle holder 0 (see Fig. 22) has a lug 9 fitting in the slot 3 of one of the sets of slots, and a retaining-plate 8 is fastened to the said lug back of the plate 0. The front portion of the holder is bifurcated (see Fig. 4) and has arranged above the divided parts, on which theshuttle rests, a curved cover or guard 0 caused by a spring 0 to bear upon the top of the shuttle 0 to hold the latter in position.

Each slide-frame c or c is provided with a lug 19, fitting one of the slots 2, and a retaining-plate 18 at the back of the plate 0,

. and carries two pointed slides or pins 12, provided with pins or studs upon which are mounted the rollers 0 0 which latter move in the slot 1. The pointed ends of the slides or pins 12 12 engage with the shuttle-holders to cause the latter to move with slide-frames c 0 and slots 1 1 are curved, as shown, to provide for the disengagement and re-engagement of the slides or pins successively with the shuttle-holders as the latter'pass into the slots of the disk hereinafter described, and subsequently above and below the cords or rig-bands J, in the manner hereinafter described.

\ To the slide-frames c c are attached racks c5 0 one of which is shown in full lines in Fig. 5, these racks engaging the gear-wheel c on opposite sides of the center of the wheel. 'Said gear-wheel 0 is placed loosely upon aspindle 0 and the sleeve or hub of said wheel carries a pinion 0", (see Fig. 3,) engaged by a gear-segment (2 Figs. 2 and 13, which is fast to a pinion d", engaged by a sector (Z pivoted at (Z and having connected thereto by the pin (1 the strap d of the eccentric 01 which eccentric is secured at the side of a wheel 61 having oppositely-placed teeth, as shown,and arms d, curved on their outer sides to fitthe plain portion of the wheel 61 Wheel 01 has "opposite toothed segments 5 5", for engagement with the toothed portions of wheel d After engagement of one of the toothed segments 5 5 with the latter wheel the concave surface of one of. the arms d, comingin contact with the smooth circumference of wheel (1 looks wheel d from further movement until in the rotation of wheel (Z the other segment thereon strikes the said arm d and rotates wheel (Z far enough to provide for the engagement of such segment with the teeth of wheel d when the segment acts to impart a partial rotation to wheel d and its attached eccentric' After each partial rotation of wheel (1 and eccentric (Z occasioned by the engagement of one of the segment-arms 5 5 with one of the toothed portions of wheel (Z the concave face of the other one of the arms (Z comes in contact with a plain portion of the circumference of wheel (:1 and locks the wheel (Z and eccentric 61 against further rotation until the nextarm 5 or 5 strikesthe arm d and communicates movement thereto. WVheel d is mounted on one end of a shaft 5, the .opposite end of which carries a gear-wheel d in engagement with a pinion d at the side of and fast to a larger pinion d which gears with a wheel (Z mounted on a stud fixed to the machine-frame and made fast. to the segment gear-wheel (Z and bevel-gear (Z which latter gears with the bevel gear-wheel at on the shaft a.

On spindle c is a sleeve 0, caused to turn therewith by a spline 'v, and carrying awheel c iadapted to be engaged when in proper position upon the spindle e by the segmentgear (Z Around the sleeve. is a groove 0 into which enter pins on the sleeve-shifter d, which is pivoted at d to a bracket on the frame and has one end forked, as shown in Fig. 2, and receives between the branches thereof the wheel (1 Upon the sides of the latter are lugs r, adapted to strike the branches of the forked end of shifter d, and

the weight-cords f From the spools f f the cords f f are led forward through the guides f f and the slots 3 3 in the plate and are attached to the pins f f Guides f f are hung by rodsh h from opposite ends of lever h, centrally pivoted at it upon the machine-frame, and having attached to it, near one extremity, one end of spring h, the other end of which is attached to the frame. The lever 7i is connected by rod 71 to lever h, pivoted at h to the frame and carrying the roller 7L5, which is acted upon guide f in Fig.5.

by cam 72 on shaft a to depress lever 71 and move lever h aboutits fulcrum, so as to raise one guide f andlower the other. Lever 7L7, pivoted upon lever 71 is connected by-rod h to arm 71*, which is pivoted at the lower end to the frame and connected at its upper end to the left-hand guide f in Fig. 5. Arm h is pivoted at its lower end at h, and at its upper end is connected with the right-hand By the alternate engagement of cam h with levers 7L7 h the guides f f are alternately caused to move inwardly slightly toward the middle of the machine.

Spindle e at its rearward end is provided with a worm 0 which engages and drives a worm-wheel 0 carrying a pin 0 adapted as the wheel rotates to engage lever 0 which, when released, is caused by spring 0 to fly against the bell c The twines or threads H H, from which the heddles are formed, are wound on bobbins o, mounted 011 the shuttles e 0 From the bobbins thes'aid twines or threads pass through eyes at the ends of spiral springs' o 0 which serve to keep the twines or threads under proper tension and to take up any slackthat may occur therein.

The operation of the parts in forming heddles is as follows, reference being had to Figs. 6 to 12: The twines H H being tied to the cords in rig-bands f f and'the shuttles standing in positions intermediate the cords f y, and the former a on the end of spindle 0 the gear d", actuated from shaft (4 through the gearingdescribed, in its rotation carries one of its gear-segments into engagement with one of the toothed portions of pinion (1 the endof the said gear-segment first coming in contact with the arm d, resting against the plain portion of the. circumference of Wheel cl, and thereby moving wheel c1 and the at tached eccentric (Z until a toothed portion of wheel (I is engaged by the segment, when the wheel is turned until the other arm (i is brought into contact with the plain portion of wheel (1 at the opposite side of the gearsegment, again locking the wheel d and eccentric from movement. The semi-rotation thereby imparted to the wheel and eccentric causes sector d to be moved to one side, occasioning, through the pinions (Z segment d, and wheels 0 0 a movement of the racks c c and connected slide-frames and shuttles inward toward the middle of the machine. The disk 0 at the end of the spindle 0 carries the circular plate 0 set in an opening in the plate 0, and having slots formed therein coinciding with the slots 3 3 in theplate 0. (See Fig. at.) Then the racks andslide-s are moved inward, as described, the holders 0 are carried into the slots in the plate 0 the bolts or pins 12 12 being disengaged fromthe said holders 0 by bends in the slots 1 1 at points adjacent to the plate 0 said bends acting upon rollers c c as the said frames move to draw the bolts or pins out of the holders and leave the latter free to move with the plate 0 hile the holders are supported by the said plate 0 a complete revolution is imparted to the spindle c and" plate through a lug r on wheel d acting upon shifter d to move the sleeve 0 endwise into position for wheel 0 to be engaged by the gear-segment on wheel (Z after which a reverse movement is imparted to said sleeve by another lug on wheel 61 to carry it out of position for engagement by the said gear-segment. By this rotation of plate 0 the cords H H are caused to wraparound the former-pin n and interlock, as shown in Fig. 6. The slots in plate 0 having been brought in line with those of plate 0 again, the bolts or pins 2 2 again engage with the holders c 0 as the slide-frames and racks move outward and the shuttles are carried out to'their intermediate positions, as in'Fig. 6. Needle e is now operated from the part 71 0f cam a 'iso as to cause the same to engage the twine from the right-hand shuttle and move outwardly therewith in the manner illustrated in Fig. 6. Next aprojection on the cam g on shaft 'b'engages lug 1' and raises sleeve b so as to cause finger Z2 to engage that portion of twine H which extends from cord f to the former a, and a projection on cam b engaging projection b" on slide b rocks lever'b moving the rod 11 and attached finger 19 so as to carry such portion to the opposite side thereof, as indicated in Fig. 7 at the right-hand side! Sleeve 19 and finger b now fall, releasing the loop of twine H, which as it moves to return to the original position catches upon the point of the shuttle and rides over the shuttle, thereby interlocking the two portions of the twine in the manner indicated in Fig. 8. The slide 19 rod 12 and lever D are returned to their original outward position by a spring 0. At the time twine H is moved into the position shown in Fig. 7 the cam h acts throughlever h link 72 lever h, and guide f to move the cord f inward somewhat, asindicated in Fig. 7, to prevent strain on said cord Hr The projection of cam 7L having passed the roller on lever 71", the weighted cord applied to the spool f acts to tighten cord f and move the same and slide f outward to their first position. This outward movement of cord f draws the loops of twine H over the shuttle and into the position shown in Fig. 8; Cam

e acts at this time to depress lever e and needle e to disengage the upper end of the latter from twine H, and the springs o 0 in the shuttle take up the slack in twine H. Needle 6 having been permitted to rise again outside the half-knot formed in twine H, as shown in Fig. 9, is drawn toward the middle of the machine by the spring 6 moving the half-knot inward next to the former n. By a repetition of the same operations a second half-knot is formed and carried inward to the former 'n, as indicated inFigs. and 11. Next cam h acts through lever h, rod h 1ever h, and rod h to raise slightly the guide f and cord f. The slide-frame is then moved outwardly, said cord f passing between the shuttle-holder and the slide-frame as these latter pass the cord, the pins or bolts, 2 2 being successively disengaged from the holder to-permit the passage. Spring h now acts to depress guide f and the cord f and the slide-frame and shuttle-holder move inward to their intermediate position, the shuttle-holder passing over the cord f in this movement. Needle 6 having been caused to rise into engagement with twine H and draw a loop of the same inward, as shown in Fig. 11, the finger b is actuated to engage the portion of said twine extending from the knot at the former to the cord f and place such portion in position, as shown in Fig. 11, to pass over the shuttle. Next a half-knot is formed by a repetition of operations, already described, and the needle (2 is actuated to force the said half-knot outward against the cord f (See Fig. 12.) In Figs. 6, 7, 8, 9, and 10 the shuttle and other parts at the left-hand side of the machine are inactive; but Fig. 11 shows that while the parts on the right-hand side are being operated to form the half-knot, whereby the heddle is connected with the right-hand cord f the parts on the left-hand side are similarly operated to form the half-knot, whereby the heddle is connected with the left-hand cord f At the bottom of Fig. 12 is shown a completely-formed heddle. The rotation of rod (1, moves bar at along the rods a and serves to feed along the cords f as the heddles are formed thereon. I 1

The wheel pin 0 lever 0 spring 0 and bell or gong 0 serve toannounce the completion of any given number of heddles.
