Application filed September 4, 1926. 'serial No. 183,782.
This invention relates to improvements in rangement of parts hereinafter described and jacquard indicators for looms and it is the set forth in the claims. 1 principal object of the invention to provide In the accompanying drawings wherein I improved means for preventing a misindicahave shown a convenient embodiment of my 5 tion from the jacquard should the loom be invention,

The lever so cludes a pair of hooks pivotally connected to 18 is connected to box rod 19 for the boxes 20. an oscillatable positioning lever. ".llhese The vibrator levers 11 will beraised orlowl. hooks are arranged to beengaged by a regucred according to which of the bones 209is'to larly moving knife which moves in a fixed become active. The matter thus far described path and as shown in said application. no:pro-' is a well-known form of box ntiotion; I vision is made to alter the relative positions The jacquard indicator mechanism of the hooks and knife edge. It is a further mounted on a frame 21 and has pivoted therein object of my invention to provide for changto an actuator lever 22 provided with a knife ing the position of the hooks relatively to the or lifter 23 and is connected by means of rod actuator therefor, preferably by making the 524i tofa cainlever 25. The latter is actuated by lugs which cooperate with the jacquard cona cam 26 secured to the crank shaft 27 ofthe trolled lever movable and adjustable as to loom so that for each pick of the loom the position. i knife or lifter 28 will be raised and lowered.
With these and other objects in view which The, frameQl has a forwardly extending will appear as the description proceeds, my arm 28 on which is pivoted as at 29 a series of invention resides in the combination and ar three-armed positioning levers 30,. The op thereto as at 55 a depending arm 56 provided corresponding; lever 50 positely extending arms of each lever are connected to upwardly extendmghooks 31 and the intermediate arm 32 is proportioned,
to be received by one or another of two cam notches 33 formed in a vibrator controlling lever 34. There is one lever 34 for eaehof the three-armed levers 30 each of said levers 34 being pivoted as at 35 to the frameQl and beingconnected at the'other end thereof to a. vibrator lifter rod 36 the lower end of which is connected as at 3'? to one or another of the" position as shown in 2 in full lines andbeing able to move to its lower position when the levers 30 are moved to the dotted line position indicated in said figure.
The hooks 31 are proportioned to be operable one at a time withthe knife edge or lifter 23 so that by selecting which of the hooks shall be raised it is possible to rock corre sponding levers 30 and therefore the vibrators 11 either to raise or'lower the latter and thus alter the position of the active box.
Thematter described as being mounted on frame 21 and the associated 1331118111213 be substantially the same as that shown in patent telly-on No. 1,554,297. The .mechanism shown in said patent to Ryon is not definite enough in its action in that the controllers for the hooks may stop at an intermediate position so that the knife 23 moves upwardly both heel-ts will be indicated thereby, a condition which of course will produce a break. lnan eifort to overcome this defect I provide a lever for each pair of hooks 31, saidlover being pivoted on a stud 51 secured to the frame 21 and having projecting laterally from the lower end thereoftln'ee sJaced lugs 52 between which extend the upper ends of the hooks 31.
Each of'said levers 50 is connected by means of upper and lower cords 53 and 54:, respec tively, to the'jacquard mechanism indicated at .T in Fig. 11 said mechanism acting to pullon but one cord at a time so that the 3 ill be rocked either to the right or left.
Each lever 50 has pivotally connected.
with a knife edge 57 andthere is interposed between each arm 56 and its lever a compression spring'58 servingto push the knife edge 57 away from the lever 50. A laterally provjecting arm 59 on the frame 21. is provided with a plurality of slots 60 as indicated in Fig. 4- and each of said slots receives a stud 1 61 having a knife edge 62. Eachstud has a reduced slabbed portion 63 to fit in theasso ciated slot 60 to prevent rotation thereof and each stud isfurther provided with a screw 64 by means of which it may be held tightly in dotted lines the corres h n t l 1 e l attcr position on the arm 59 and also zuljuslicd VH1? tically in the slot 60..
In operation the jacquard mechanism will pull upon one or another of the cords 53 or so that the levers 50 will be rocked either to the right or to the l aboiiit the stud 51. lWhen lever 50 moves '1 the posit on indicated in full lines in l. 2 to that shown in ndino' arm 56 will i moved downwardly so that the knife edge 5'? Wlll slide over the upper inclined face of the lug 61 and pass knife edge {32 of the lugs. Th pressure of spring 58 will thereafter serve to continue the movement of the level-'50 even though the cord should not receive its full .mov nent due to the stoppage of the loom. at an intermediate position or for any other reason. Adjustment of the posinions of the lever 50 may be obtained by varv ing the vertical position. of the lug 61, the
ra'isingof the lrgs carrying the'armfilr upwardly and therefore causing a slight right hand movement. of the levers 50 so that the hoollsfil may be positioned with respect'to the knife 23.
From the foregoing it will be seenthat I have provided simpleandready means for I I i tion of-the levers 50 and alrin proper action between the co e e .ges, the lugs 61be1ng free from the ob ection previously noted with reg ard to I the plnn'gers heretofore vusedand the whole arrangement occupying less space than that required in the structure setforth in my copending application. i p
