A. CLAUS. shedding Mechanism for Looms.
`UNITED STATES PATENT OFFICE.,-
ADOLPH CLAUS, OF LOWELL, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO JOSEPH S. LUDLAM, OF SAME PLACE.
SHEDDING MECHANISM FOR LOOMS.
SPECIFICATION forming part of Letters Patent No. 243,361, dated June 28, 1881.
` Application tiled January 8, 1881. (No model.)
To 'all whom it may concern Be it known that I, ADOLPH CLAUS, of Lowell, county ot' Middlesex, State of Massachusetts, have invented a new and useful Improvementin SheddingMechanisms forLooms, of which the following description, in connection with the accompanying' drawings, is a specification.
This invention relates to that class of shedding mechanisms for looms known among weavers as dolobies,7 and is an improvement on United StatesPatent No. 217,589, July 15, 1879, to which reference may be had. The devices or parts in this application common to the said patent are designated by like letters herein. In that patent the hooked jacks are raised and lowered, to place them in contact with thelifters, through the intervention of rods provided each with two collars, the said rods being eX- tended through guide-bars, which direct their movement, cach rod being extended through horizontal slots in two of the said jacks on one connector, a single tnger on a pattern-chain operating a single rod, the latter by its two collars controlling the rising and falling motions of the two jacks, through which it is extended.
In the loom referred to, when the hookedj acks and their pivoted connectors have to be removed, as is frequently necessary, on account of the breaking of a jack or bending of parts, the cross-bars above the said hooked jacks have tirst to be removed, and also the rod controlling them, before the jacks can be taken from the loom, this requiring very considerable time. It has been my object to so improve the said loom that the jacks may be instantly removed whenever desired, and so that each jack of the upper andlowerseries may be operated directly by its own finger.
Figure 1 represents, in side elevation, the devices employedin the patented loom referred to for operating the lifters and pattern. Fig. 2 is a sectional detail, showing the heddle-levers, notched jacks, and my improved devices for raising and lowering them at the proper times,in order that they maybe engaged by one of the lifters. Fi g. 3 is a right-hand end view of Fig. l, partly in section, the pattern-chain, heddle-levers, and jacks shown in Fig. 2 being added. Fig. 4 represents one of my ringer-connecting rods attached to the iingers, but removed from the machine; and Fig. 5 is a side view ot' one of the said rods. I
A pinion, j5, supposed to be at the end of the usual crank-shaft of the loom, engages the pinion k, having a crank-pin, o5, joined by the rod p5 with an arm of Vone of the levers rf on shaft m, the said levers having links co5 a5, connected with the litters 85 t5, adaptedrto slide in the slots x5 as the said levers T5 are vibrated, the said lifters engaging the notched jacks d or c6, according to which one ofthe said jacks is lowered into a position to be caught by the said litters.
The heddle-levers x4 are joined, as usual, by cords w, with the upper portions of the harnessframes. (Not shown.) These heddle-levers x4 have slotted bearing portions 17, to receive the fulcrunrpins lt, located at the centers of the jack-connectors f6, to the lower and upper ends of which thejacks d6 c are pivoted.
The shaft, upon which is secured the gear 7c5, before referred to, has atits otherend the bevelgear l5, which engages the bevel-gear m5 on a short vertical shaft, having at its top a wormgear, a5, which engages a worm-to0thed pinion, e5, fully described iu the said patent, it being placed upon the shaft c5, (see Fig. 3,) fully described in the said patent, the said gear being instrumental in giving motion to the pattern chain or surface d5, composed of bars 26 and suitable pins thereon. The notched jacks in the said patent are slotted for the passage through them of the rods, on which are placed the projections or washers which lift the said jacks. A cross-bar of the said patent, directly above the jacksd, (see Fig. 8 of the drawings pertainingthereto,)prevents the saidjacksfrom being lifted from the upper ends of the rods 116 therein shown 5 and to remove the said jacks it becomes necessaryto rst take away the said cross-bar and then remove a similar cross-bar from above the lower series of jacks, c6, after which the jacks d6 may be turned upward from theends of the said rods bG; but the rods cannot be removed until the front side or cap part (not therein shown as removable) is removed from the guide, (shown in section as located below the hooked jacks di) in which the rods b6 slide vertically, and then thehooked jacks IOG and their connectorf and rod may be freely removed from the loom.
In this myimproved loom thejacks are lifted by a series of weighted Yfingers, a7 bl, pivoted at a bg, each inger having a toe, am or Z212, at its inner end to bear against the curved under side ot and keep the jacks c6 d elevated out of range of the lifters S5 and t5, which are moved simultaneously in opposite directions. The jacks are lifted whenever a finger, al, is permitted to fall into its lowermost position (see Fig. 2) by the absence trom under it of a pin of the pattern-chain d5. The outer ends of these weighted fingers a7 117 are joined by adjustable wire links c7 e8, each one having near its center aloop, o8, which may be pinched or closed more or less, as may be desired, to provide for Wear of the parts and to insure accurate adjustment and position with relation to each other and the pattern-chain of the iin gers a7 bl.
In this my improved loom the jacks 0G d6 are not slotted, and are consequently made much thinner and stronger than were they slotted, and, besides being more cheaply made, are less liable to be broken or injured in use.
When for any purpose it is desired to remove from the loom a connector, f6,and its attached jacks d5 c, it is only necessary to lift the pivots of the connectors from the slotted portions 17 ofthe heddle-levers nvt-and elevate them out of the machine, the hookedjacks d6 being free to readily pass underneath the cross-bar dl above them.
Some ofthe parts shown in the drawings being not of myinvention, and being fully shown in the patents hereinbefore referred to, I have deemed it unnecessary to fully describe their operation, notwithstanding Ihave placed upon or near them letters of reference common tothe said patent.
By the employment of the fingers al bl, one for each jack, and connecting the outer ends of the fm gers by means of theadjustin g devices orwires ci, I am enabled to move the said fingers in unison together in the same direction, and consequently with them the hookedjacks c6 d6, thus enabling me to do away with the rods b6 and their washers 15 and 16, (shown in the said patent,) and also avoid the making of slots in the said jacks, which, in my opinion, weaken the said jacks.
I claim- 1. The heddle-levers x4, the series of connectors f6 and their attached hooked jacks c6 d6, litters 85 t5, and means to move the said lifters, combined with the two independent series of fingers al b?, one finger for each jack, the wires or connectors c" between the said fingers, the pattern chain or surface, and means to move it, substantially as and for the purpose described.
2. The two series of weighted lingers al b", their connecting-rods c7, provided with loops o8, the pattern-cylinder, and means to move it and actuate the said iingersin unison, combined with the hooked jacks operated upon directly by the said lingers, the connectors between the hooked jacks, the lifters, and means to reciprocate them to engage anyot' thejacks which may be permitted to fall Within their range of movement, substantially as and for the purpose described.
ln testimon)v whereof I have signed my name to this specitication in the presence of two sub scribing witnesses.
ADOLPH CLAUS.
