There is herein disclosed adaptation of my in vention, ini'oneof its many-forms, to both a single I shuttle loom and a multipleshuttle loom. The adaptation to' a single shuttl'e loom' is illustrated in Figs. 1-4, inclusive, and this 'fo'rm will bedescribed first.

Y r v V The' binder body is r ecessed as at -16 toreceive the elementfifi whizih is slidablymounted therein for movement longitudinally and laterally-of the lay 'iand -shuttlem flie element 15 may Joe -preventedifrom idropping out of the-recess "16 by any suitablwmearissuch as metalplates -lfi and 18' secured respectively to the upper and-lower surfaces eof the bi'nde'r b'o'dyas' by wood screws 19. The upper plates 1:7 am b'e'nt "downwardly; at 20, and the lower plates:are bent upwardly at 21, into recesses in the element 1 5; Flat- metal plates 22 and 23 may bese'cured to theelement 15 by screws 24,- wvhich ipla'tesacoop'e'rate with the first mentioned .plateS-lib shol'd'ath'e element in the recess 1 6. FA coiledispninge ZSJmay' he positioned -i'n a recess in the binder body to engage a lug 26 on the element 15 and yieldingly urge the latter toward the right hand end of the recess. This spring is intended merely to prevent vibration of the element 15 and may be omitted.
The plates 22 and 23, which are parallel, are inclined at an acute angle to the longitudinal axis of the binder body and constitute cam surfaces. Cooperating cam surfaces, similarly inclined, are formed on the binder body as at 27 and 28.
The incoming shuttle engages the element 15 (or lining thereon) and moves the element bodily longitudinally of the shuttle box. The cam S111: faces mentioned serve to also move the element inwardly toward the shuttle to pinch and thereby check the latter. The angle of the cam surfaces may be varied, as may the resistance of finger 12. Depending on these and other factors, the checking action of the element 15 may take place almost entirely after it has been moved to the outer end of the recess 16 or may take. place while the element is being so moved. In eitherevent, actuation of the element by the shuttle serves to increase the effective thickness offthe binder and, therefore, to increase the effectiveness of the checking action. I
It will be apparent that whenttheshuttlefirst starts to move out of the shuttle box on the next pick the element 15 will move-longitudinally and outwardly, i. e. rearwardly, of the shuttle box and thereby release the binder pressure on the shuttle. Whether thisrelease is only partial or is substantially complete is determined by the length and angle of the cam surfaces'and the adjustment of the finger 12, which may bevaried: as desired. Y
The foregoing construction-serves to veryefilcaciously check the shuttle withoutv unduly wearing the same and, atthe same. time, imposes much less than the usual resistance'to the picking of the shuttle outv of the box. .As'a matteroffact, I have been enabled, by this construction, toaccomplish all of the checking action in the shuttle box and thus dispense with the usual check straps or other expensive and troublesome checking devices, I
The adaptation of my invention'to ashifting. shuttle box loom, as embodiedinthe construction shown in Figs. and 6, will now be described. Such a loom employs alternately active (and alternately inactive) shuttles. The lay 30 carries inner and outerv box guides 31 and 32 between which a shuttle box 33 is mounted for vertical reciprocation. The shuttle box is provided with a plurality ofshuttle-receiving cells, as 34 and 35,
and is shifted up and down by a lifting rod 36, to align one andthen the other of the cells with the race plate of the lay. A sliding picker 37, mounted on picker rod 38, is actuated by a connection 39 and picker stick 40. The picker projects into. the shuttle box and will engage the point of the shuttle 41 in whichever cell is aligned with the race plate.
The incoming shuttle is received in the shuttle box approximately to the position shown in both Figs. 5 and 6. Thereafter the picker is disengaged from the shuttle in the usual manner and the shuttle box is shifted up or down, as the case may be, before another. shuttle is picked. The box guide 32 is provided with a rearwardly projecting portion 42 on which areformed inclined shuttle positioning surfaces 43, and 44. As. the shuttle box moves up or down the tip of the shuttle which is being movedfromactive to inactive position engages one or..the other. ofthe surfaces auxiliary.
43, 44 and the shuttle is thereby cammed longitudinally of the shuttle box to a predetermined position wherein the tip of the shuttle can just contact a vertical guide surface 45.
The positioning of the shuttle longitudinally of the shuttle box in the manner indicated is done for several purposes. Among these may be mentioned the necessity of having the shuttle occupy the same position each time for proper cooperation with a feeler (not shown) and the necessity of having the shuttle positioned away from the end of the picker when the shuttle is shifted to or. past the picker by the shifting of the shuttle box. Such positioning means, and the other parts of the shuttle box thus far described, are old and well known in the art. The protection mechanism, of which finger 46 is a recognized part, is likewise old and well known.
Each cell of the shuttle box is provided with a binder. The upper binder 47 and the lower binder 48 are pivoted at their left hand ends, as at 49, and each binder is provided with a movable shuttle checking and releasing element 50. Outward movement of the binder may be limited by a pin 51.
The binders 47 and 48, including the elements 50 are herein shown as beingidentical with the binder shown in Figs. 1-4 inclusiveQexcept that the binders 4'7 and 48 are reversed so as to fit in thefront of the shuttle box. Consequently, further detailed description of these binders should be unnecessary.
The shuttle checking mechanism of my invention, when applied to a shifting shuttle box loom, is possessed of the same advantages as when applied to a single shuttle loom and is possessed of one further very important advantage over prior art constructions, as. follows: H
In prionconstructions the binder pressure on the shuttle being moved from active to inactive position imposed considerable resistance tothe longitudinal positioning of the shuttle by guides 43, 44 or their. equivalent and such resistance caused rapid wear or mutilation of the guides and the shuttle tips. My invention, on the other hand, provides means for releasing or lessening, the binder pressure on the shuttle simultaneously with the positioning of the same. There is, therefore, in my construction, much less resistance to longitudinal movement of the shuttle by the positioning means with a resultant substantial lessening of the mutilation of guidesrand shuttles. 1
It will be understood that numerous changes may be made in the constructions herein disclosed-the true scope of my invention being defined in the appended claims. 7
