STARTING AND STOPPING MECHANISM FOR LOOMS.

To all whom it may concern:

Be it known that I, ALoNZo E. RHOADES, a citizen of the United States, residing at Hopedale, county of Worcester, and State of Massachusetts, have invented an Improvement in Starting and Stop )ing Mechanism for Looms, of which the fo lowing description, in connection with the accompanying drawing, is a specification, like numerals on the drawing representing like parts.

The apparatus forming the subject matter of United States Patent No. 867,934, granted to Ambler, October 8, 1907, provides mechanism for throwing on or off the power, in a loom, the construction and arrangement being such that not only is the shipper easily moved from running to stopping position but the opposite movement, viz: to running position, can be effected by the expenditure of very little force or strength.

In practice, even on a broad loom, the weaver can with one finger move the shipper to running osition, but this very desirable and valuab e characteristic opens the way to accidental shipper movement as easily as when such movement is designed, and it will be apparent that should the weaver unwittingly move the shipper to running position while working about the loom serious injury might result' My resent invention relates more particular y to loom starting and stopping mechanism of the type referred to wherein the shipper movement is so easily efiected, and it has for its main object the improvement of such mechanism whereby the shipper is locked automatically in stopping position, so that it cannot be thereafter moved to running position until unlocked.

The unlocking is effected manually, either immediately adjacent the shipper or at a point distant therefrom, and another obj eet of my invention is the production of an instrumentality whereby the weaver may move the shipper to running position from such distant point, the actuation of said instrumentality operating first to unlock the ship er.

T e patent referred to provides means for starting the loom from different )oints at the front of the loom, a very usefu feature,

articularly on broad looms, and I do not broadly claim such means herein, but I have arrangedfor the stopping of the loom through Specification of Letters Patent.

Application filed. July 7, 1908.

Serial No. 442,339.

the same instrumentality and for the unlocking of the shipper, as before mentioned.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a left hand side elevation of a sufficient portion of the starting and stopping mechanism of the Ambler patent to be understood, with one embodiment of my present invention applied thereto, the ship per being shown in stopping position and locked; Fig. 2 is a front elevation of such devices, with the breast-beam and shipperoperating member or rod broken out to save space, and the greater part of the controller adjacent the shipper is also broken off; Fig. 3 is a detail similar to Fig. 1 but showing the shipper in running position, the controller being omitted to avoid confusion.

Referring to the drawings the loom-side 1, breast-beam 2, the shipper comprising a long upper member 39, shorter lower member L1, connected by a'hub 42 fulcrumed on the stud 43 extended from a bracket 43 the link il connecting the lower member 41 of the shipper with the devices to throw the power on or oil, the stops +13, 40 on the bracket 43 the brake-governing link 59 pivotally connected at 60, Fig. l, to an ear (31. extended from the controller (32 fulcrumed near its lower end on the stud 45% along side the shipper and having below the fulcrum stud 43 an extension 64 provided with a lateral too 65, shown in dotted lines llig. 1, extended back of the shipper member ll and cooperating with an adjustable stop 66 on said member; the rod 71 mounted in bearings, as 72, on the breast-beam and having a rigidly attached and depei'iding hooked arm 73, and the car 74: on the shipper member 39, provided with a lateral pin 7 a with which the arm 73 is ad apted to cooperate, may be and a n all substantially as in the Ambler patent referred to.

W hen the controller 2 is thrown forward, or to the right, Fig. l, the link 59 causes the brake to be released, as in said patent, and when the controller is thrown into the position shown in Fig. 1 the toe (i5 acts against the stop 66 to move the shipper to stop )ing position while the operation of the lin 59 causes the brake to be set.

Herein l have shown a latch 23 fulerumed at 4 on the longer member 39 of the shipper,

andiforming one member of a shipper locking means, the tail 5 of the latch extending rearward and having pivotally connected with 1t the lower end of an upturned rod 6 extended slidably through a hole in the bottom of the tubular handle 7 of the shipper, as shown in Fig. 1. Y

A head or finger-piece 8 on the upper end of the plunger or rod 6 projects above the open top of the handle and is acted upon by a coiled spring 9 within the handle, said spring acting under normal conditions to maintain the latch in operative position, with its tail against a stop 10, see dotted lines Fig. 1, on the side of the shipper.

By pressure of the thumb or finger on the finger-piece 8 the rod 6 is depressed, lifting the latch on its pivot into inoperative position, as will be obvious.

A rearwardly extended stop-arm 11 has its hub 12, Fig. 2, loosely mounted on the.

latch 3 clicks over the stop 13 and snaps into cooperation therewith, as shown in Figs. 1

and 2, locking the shipper in stopping positlon so that it cannot be moved therefrom until either the latch or the stop is moved into inoperative position.

The Weaver can unlock the shipper by pressing down the finger-piece 8, as described, thereby lifting the latch above the stop 13 so that the shipper can be moved forward to running position, the handle 7 being grasped. to effect such movement.

When the shipper is locked any accidental forward push or pressure upon it is resisted by the locking means, so that the loom cannot be started unwittingly, and it will be seen that the unlocking if effected by means adjacent the shipper does not change the position of the stop 13.

YVhile the stop-arm 11 is loose on. the rod 71 the pressure exerted thereon by the latch,

should the shipper be pressed forward, acts in a line through the axis of the rod 71, so that no turning tendency is imparted to the sto -arm. Said rod 71 has fast upon it a col ar 14, Fig. 2, adjacent the hub 12 of the stop-arm, and a spring 15 coiled about the rod is attached at one end to the hub and at its other end to the collar, the winding of the spring being such that when the rod is turned in the direction of arrow 16, Fig. 3, the spring will tighten and turn the stop-arm 11 to depress the stop- 13 out of the path of the latch 3.

A lug 17 on the collar extends behind a projection 18 on the hub 12, to positively return the stop-arm to operative position when the rod 71 is returned to normal position.

Supposing the parts are in stopping position, Fig. 1, then if the rod 71 is turned in the direction of arrow 16 the shipper-locking means will be rendered inoperative, as described, and the hooked arm 7 3 will engage the pin and will thereby move the shipper forward into running position, Fig. 3, against the lug 19, the yielding connection between the rod and the stop-arm permitting the full angular movement of the rod after the stop 13 engages the top of the breast beam. When the rod 71 is released the'arms 73 and 11 return to the position shown in 1.

Viewing Fig. 3, it will be seen that a lateral lug 19 on the arm 73 bears against the front edge of the upper member 39 of the shipper, and if new the rod 71 is turned oppositely to arrow 16, said lug 19 will act upon the shipper to throw it rearward into stopping position, the latch 3 clicking over the stop 13 during such movement of the shipper. While the movement of the rod 71 to move the shipper to stopping position slightly elevates the stop 13 temporarily it is not suflicient to prevent the riding of the latch thereover, and the latch operatively engages the stop to lock the shipper in stoppmg os1t1on.

1 will now describe the means for manually actuating the rod to move the shipper into running or stopping position.

Referring to Fig. 2 said rod has iixed upon it at a point distant from the shipper, for instance at or near the right hand side of the loom, a collar 20, secured by a set-screw 21 and provided with a short depending extension or actuating handle 22. When the weaver wishes to stop the loom when he is at a distance from the shipper or the controller 62, he presses the handle 22 toward the breast-beam, thereby turning the rod 71 oppositely to the arrow 16, and the lug 19 acts upon the shipper and moves it to stopping position, as has been described, the locking means operating automatically to retain the shipper in stopping position. The collar 20 has a lateral lug 23 which extends into a segmental recess 24 in the adjacent end of the hub 25 of a depending handle 26 loosely mounted on the rod between the bearing 72 and the collar 20, the handle 26 being preferably longer than the handle 22. 1f the loom is at rest and the weaver wishes to start it other than by direct grasp of the shipper he pulls the handle 26 forward and upward, until the lower end. of the recess 24 engages the lug 23, further lifting movement of the handle 26 then acting through said lug and the collar 20 to turn the rod 71 in the direction of arrow 16 and moving the arm 73 forward. Said arm acts against the pin 75 and moves the shipper forward to running position, Fig. 3, and the stop cc acts upon the toe to correspondingly swing the controller 62 and effect release of the brake.

The lost-motion connection between the handle 26 and the rod 71 is similar to the connection in the Ambler patent, obviating any tendency to apply undue force in operating the rod.

The handles 22 and 26 may be termed stopping and starting handles or actuators, respectively, and both can be actuated at a point distant from the shipper, a matter of great convenience in broad looms.

My invention is not restricted. to the precise construction and arrangement herein shown and described, as the same may be varied or modified in different particulars by those skilled in the art without departing from the spirit and scope of my invention as set forth in the appended claims.
