SOLOMON KAMELGAR. OF PATERSON, NEW JERSEY.

sfror MOTION non Looms;

Application filed July 9, 1921.

To all whoml it may conce/ML:

Be it known that L SOLOMON Klinsmann,

ing means operates to more another shuttle.

into the same; for example, see my patent No. 1,358,21. Such mechanisms are usually constructed with a dagger to actuate stopping mechanism and whose position tor that purpose is determined by 'feeling devices, as protector rods, one for the box or boxes at each end ot the hatten; and heretofore this dagger was adapted to actuate the stopping mechanism on the Yforward stroke olf the hatten. In the case ot a box loom there is a condition which may arise in which the mechaiiiism would tail to prevent a smash; this condition arises out ot the fact that the changing o'l the lliores in a box loom takes place when the hatten is forward and will arise thus, it'or example: whenever the weaver, a'iter a stopping ot the loom, places a shuttle in a box which at the time ot starting is not alinedwith the hatten but becomes aimed therewith when, the batten hein forward, the changing oit the boxes talles place. The improved mechanism is cluuacterized by the employment ot a dagger which actuales the stopping mechanism on the l'iaclrstroke oi the batten-that is, at a point so thu: delayed in the cyclo oit the bat-r vteus movement from the time ot one pick to that oi the next that it will take care ot a smash-piroducing disposition of the shuttles under any conditiom including that explained above.

In the drawings,

Fig. l is a plan showing the hatten structure, the hreast-beain-including part oli the loom `lira-ine and my mechanism, the hatten structure being more or less back;

Fig, Q is a vertical sectional View of what is shown in Fig. l and showing also the crankshaft and pitman, the hatten structure being approximately fully 'forward and the dagger Z being in the normal or depressed posit-ion so that as the hatten reciprocates its hook i will play under the lever 2;

Serial No. 483,434.

l Fig. l is a vertical sectional View ot what is shown in Fig. l on a. larger scale, the hatten structure just starting to recede and the dagger Z being raised by the falling of theblock m` so that its hook Z is now in position to catch and pull on lever 2 and so act therethrough and` through crank l to turn the rock-shalt j" l'or stopping the loom and shifting cam-hump 71, to dowmrardly proj eating position; Y u

Fig. lf is a 'front elevation oli certain parts at the moment lwhen the downwardly projecting cam-hump 7;. acts to depre. the dagger l (as the hatten structure continues receding) clear of lever 2 and reset it and block m; and

Fig, is a plan of the parts shown in Fig. -flf in the positions they occupy in that ligure.

The loom trame as; breast-beam Y), hatten c; single shuttle-box cl; vertical series of shuttle-boxes e moved up and down in the usual way by any known means; the binder c Yfor each ot the shuttle boxes; lthe knockoil' shaft journaled under the breast-beam and the handle. thereon; the plate YFormed with a vertical. dovetailed groove y' and having a depending arm 7c; the block m slidablc in said groove and normally held down gravity and a spring n and having a depending stem m and a orossout or horizontal groove o; and the alined detecting or protector rods p journaled iin brackets f] on the hatten and each having at. its inner end a crank r engaged in groove 0 ot the block and held therein by a spring 1J' coiled about the rod and secured at its respective ends to a collar u on the rod andto the. bracket (j, the outer end ol the protectorl rod `adjoining` the series ot boxes having an Aarm o which bears aga-inst the sluittle-binders e of those boxes and the outer end ot the other protector rod having a crank w wliiich bears upon the forwardly projecting arm ot a lever :c bearing against the binder e for the single bo); Z are or may all be the same as in my said patent.

The element g in the present case is a cam .'liXed on the knock-ott shaft't 7 in such relation that when the shaft has been rocked to stop 4the loom the hump or toe 7L on the cam projects downwardly.

The dagger Z, piroted to arm 7i: and haying stem fm. piyotally connected to its rear end, has a forward laterally deflected hook and an upstanding depresser arm l which plays back and i'orth with the hatten in vertical plane of and under the cani g. fiala! hooi:7 when the hatten moves back and Yforth, normally plays under and clear oit one enti ot a leve r Q tuloruniecl in a bracket 2i on the breast-livin, the other end oi'n said lever being` back of a depending Granit l on "the linool't-oit sha'iit j?
