Description

o To all whom-'it may-concern: l

Be it known that I, GEORGE ROTH, of the city and GEORGE Horner Nui-2v YOREN. YQ, AssIeNon` Tor HEINEMANN r yANDlsiLesruviANN,or SAME PLACE. i

Letters Patent No, 95,145, 'dated September 21, 1869.

` The Schedule referred to` in these Letters Patent and making part of :he same,

State of New York, have invented, made, and applied `to use, anew and useful Improvement in Looms for Bulliou-Fringes; and I do hereby declare the following to he a full, cleat-,and exact description of the said i n 'vention,`reference `being had to the annexed drawing,

making part of this speccation, whereinf' Figure l is a side View of the loom, with the lay `near the extreme backward movement; l FigureZ is a plan of l `the loom below the line a: x, ab" f yFigure?, is a rear viewl of the stop-motion forthe bullion-hook; and l Figure 4 isa section `of the lay and slide, and an elevation ofthe stop-motion for the hook.

Similar-marks'of reference denote the same parts. This invention is devised for weaving and twisting bullion-fringe. Looms havebefore been made to effect this, buttheyare more complicatedl and liable to get out oforder. p, i

My loom is shown as made to Weave one piece of fringe, but by multiplying the number of twistingl uhooks andtheir actuating-gears, theloom may be made to weave several pieces of inge at the same time, `similarly to the'weaving of tapes. The weaving of "theheadof the 'fringe is similar to that of any ordinary weaving. The cord to be twisted to'iform the bullion is drawn in by a hook that isrevolved` after the shed is changed, and then i stopped by peculiar" mechanism, and thebullionuu-- hooked by a finger actuated by a bent lever.

In twisting the'bulliomthe twist-is `liahleto extend up into Athewoven head, and'mar its flat appearance.

" `This hasheretofore been 'prevented by Wires that ale liable to become Vmisplaced orinjure the fabric.

`I introduce in the reed and heddles three ormore i heavy threads or finecords, which, beingwoven'with the head, at the edge thereof, preventthe twist extending up into the woven ornamental heads, and after the `fringe is complete these threads are cut and pulled In the drawing l I a represents the frame of theloom. j

b, the lay, hung 4toswing from above, and moved`by the cranks c l and connecting-rods c` d' from the main shaftle, or in. any other convenient manner.

e. is the gearingthat is employed to actuate the heddlesf through anfupper rock-shaft; and' at f is the gearing `forming 'the takelnp motion to the rollei g,

upon which the-fringe is wound. y is the breast-beam, and 2, the sustaining-loop o 5 l roller, around which the fringe passesto the roller g.

"Iheseparts, heretofore described, being of knownl construction, and forming no part ot' my invention, re#

quire `nofurther description.r

The cord that forms .the bullion, passes from ,the spool h, to which a friction-detention isapplied, and is led through the eye 7c that is formed in a wire that is projected upward to a` spring, 3, and passes down to `the treadle' It that is operated by the earn l, so as yto raise the bullion-cord as the hook c' is moved endwise through the shed, and then the eye k descendsto lay the said cord upon the shank ofthe hook, so that the hook takes said cord, and draws it `through the shed/by an end vmovement given to the same, and then the'hook i is revolved to twist the bullion, and asthe lay and hook swing back, the bullion comes over the linger r, the hook is stopped with the point upward, and the fingerr` lifts the bullion oil said hook.

The means for giving these motions will next be described. l f

The rail of the lay b carries the slide-bar m,`upon which are mounted the bearings 5 for the shank'of the hook l,and'the partsthat actuate it.

This slide-bar m is moved endwise at the proper time by the lever n, links 6 and 7, lever p, and cam q, on the main shaft e, and the level' a is provided with a movable fulcrurn, 8, so that the end movement given to the slide m and hook 'i can be varied, andconsequently the length ofthe bullion of the fringe increased or lessened.

Upon the slide m is a standard', t, that is guided by a bar, i), on the swords of the lay.

The shaft s that' communicates a revolving motion to the hook i, through the wheel 10 and pinion 11, is

by apawl and ratchet, 12, the barrel c, to which a cord i` or band, 13, is applied, the same being wound around the barrel, and attached near the middle 'of the cord,

and one end passes oii to the spring 14, and the other `to the lever fw,- and from the other end of this lever w is a' connection,`15, to the lever w', which) receives motionat the proper" time from the cam 16, which is so shaped as to act upon the lever fw', press that down,

- swing the lever w, draw the cord 13, and rotate the barrel c, Wheel al, pinion 17, shaft s, gear 10, pinion 11, and hook c', twisting the .bullion at the time the shed has changed, and the loop of .bullion-cord been.' vbeaten up by the lay b and reed 18.

The. ratchet and pawl 12 allow the barrel to be tilrnedlback by the spring 14 without rotating the other parts, and I remark that the fulcruln ofthe lever w is movable, so as to increase or lessen the motion of the cord 13, and the consequent twist-ing of the bullion more or less, according to its length or character.

'It is necessary that the hook'i bestopped with the hook upward, so that th'e finger' 1' may lift the bullion oo the saine. To do this, I provide stops 20 on the anni' am ,1' n

Shaft s, adjacent to the pinion 17, the parts being so proportioned that when either one -of these stops 20 comes against the end of the pawl o, the hook t will be uppermost.

This pawl o is on a plate, 21, that has a stop to hold up the pawl 0, the two swinging on the same centre.

Behind the standard t is a bent lever, 22, on a fulerum, 23, and having a hinged dog, 24. A

As the slide/m is moved along, the dog 24 comes into contact with the pin 25 on the lay, andinoves the lever 22, so as to depress-the back end of the plate 21, and lift the pawl o, and retain it out of contact with the stops 20, and from the lever 22 a cord, 28, passes to the vlever w, so that simultaneously with the iinal revolution of the hook i, bythe movement of the lever w, the lever 22 is raised, so as to drop the pawl o, and arrest the movement of the parts, so that the hook 'i remains with its point uppermost.

The mode of actuating the fingern now `alone remains to be described.

rlhis finger fr projects from the horizontal arm of a bent lever, 29, and the vertical arm is connected with the vertical arm of a similar lever, 30, and from the horizontal arm of this lever 30 alink, 3l, connects to the lever 32, at the end of which is a tumbler-latch,

33, that is turned down by a projection, 34, on the lay b, as the same moves to beat up, but as the lay b goes back, this projection 34 takes this tumbler-latch 33, and the lever 32 is thereby depressed, and the parts moved to raise the nger fr, and unhook the bullion from the hook t.

The warps forming the head of the fringe are to be of silk, or other suitable material, and those on the side from which the bullion projects are to be heavy threads or cords, for the purpose aforesaid.

\Vhat I claim, and desire to secure Patent, is-

1. The hook i, mounted upon the lay 71 and slide fm., in combination with the mechanism, substantially by Letters specified, for revolving said hook, and stopping the' same in position for the bullion to be nnhooked, substantially as set forth.

2. The nger fr, mounted upon the bent lever 29, and actuated by the movement ofthe lay, substantially as set forth.

1n witness whereof', I have hereunto set my signature, this 2d day of August, 1869.

GEORGE ROTH.
