I

My invontion relates to n warp atop p10- tion for looms, and Ysrticuiarly to improvemonta in mechanico warp atop motions of the shown and doacnbed m U. S. Lettoza otent No. 6%,718, dated January 8 3.2261. In a warp sto motion shown on in aid pom film is s cm iocnio on-tim boiiom shaft, which o ooratoa, @iarougia as con love: and miormmiinio conto o vibmior, mid viiaroior, to como moiion tiioi'oto, nnri to m some in ior tho oogo @ovaoza silo inroads.

riii, onri ndop o gage the dagger 20, on the forward movement of the lay, when said dagger is lowered on the breaking of a warp threud,'to stop the loom in the usual way.

' he stud 16 on the upper end of the lever 13, in its inoperative position is centrally locatedwithrelation to a stu not shown, on the frame 9,.on which stud is pivotallv mounted the hub'15' of the lever 15, which lever is an angle or elbow lever; The lever 13 has on one edges. fiat surface or projcction 13'7', against which bears the engaging end of a positioning device 24, which as a straight face or engaging surface, and

is carried on a slide rod 25, movable -in suit- .able ears or projections 15" on one arm of the lever 15. The end of the lever 15 carries a stud 96, which carries a block 27 which adjustably receives the upper end oi a connector or rod 28; the lowerend of said connector 28 has a boss 28' thereon, which is pivotally connected to astud 29 on a collar 30, which is adjustsbly secured by a set screw 31 on one end of a rod or bar 32.

- The rod 32 is in this instance bent inwardly at its other end, and is threaded on said end. The bent end of the rod 32 extends loos-sly through a'hole in the lower end of the carn'leveras, and also through a hole in the cam lever foot portion 88, which in this instance is made separate from the cam lever as. The foot portion 83 has in this instance an extension thereon, which fits into a recess in'the lower end of the cam lever 34, m Fig. 2. Nuts 89 on thethreaded end of the rod 82, one on the outsidsof the cam lever 84, and the other on the inside of the shoe' portion 83, see Fi 2, smures the foot ortion 36 to the end 0 the cum lever 34, on also secures the rod 82 to the cam lever 84 and the footportioh 38. The foot portion 88 of the cam lever 34 travels upon thepcrighe of, and is o ich secured on t e bottom s sft fifi.

The com lever 34 has its hub 34 pivotally mounted on a stud 87 on a stand 88,1u'id through a stud 89, adjustehloin a slot 84" m the lever 84, is adjuetably conuemd with an extension 40' on the filling fork lever 40, which has its hub pivotally mounted on the stud 87. The upper end of the filling fork lever 40 extends within the filling fork slide l1, which carries the filling fork 42, and is adapted to move said slide to operate the ship ing mechanism in the usual way.

All of the above mentioned parts, except the arm 32 connected with the connector 28, and the foot portion 33 on the ,cam lever as,

are of the usual and well known construction, and as shown and described in the Patent, No, 665,713, above referred to.

The advantages of my improvements will be readily appreciated by those skilled in the art.

From the cam 35 on the bottom shaft 36, \vhiclnopcrates the cam lever oi the filling stop motion, through the cam 32 connected to the foot portion 33 on the cam lever 34, and the connector 28, a vibrating movement is communicated to the vibrator, and the other parts of the warp stop motion are 0 ernted in the some manner as described in said Patent, No. 665,713, and the additional cam on the cum shaft, and the intermediate connections to the connector 28 are done away with.

It will be understood that the details oi construction of my improvements may es varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Potent is In a loom, the combination with a. driven cam, a cam lever, and a so arate toot portion thereon, traveling on he periphery 03" said cam, and s, filling fork slide operated by said cam lever, of s. warp stop motion, and connections from said warp stop motion to said cam lever, said connections-neonaprising a connector, connected at one end to the warp stop motion, and at its other end ivotally connected to a collar, and said col-' or, fast on a rod or bar, and said rod or ban-bent at its attached end, ssid end being threaded and extending through an opening in the cam lever and in the foot portion oi said cam lever, and bolts for securing-said rod or bar and the foot portion to said cam lever.
