WEFT STOP-MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent N 0. 393,935, datei December 4, 1888.

Application filed October 3, 1887.

To all whom it' may concern.;

' Be it known that we, VILLIAM TAYLOR and CHRISTIAN G. SAALFRANK, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements vin lVeft Stop-Motions for Looms, of which the followingl is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to mechanism for stopping the running of a loom upon the failure of the proper supply of the weft or lling in the loom, whether the failure be due to thel'n'eaking of the weft or the depletion of the same from the shuttle.

The object of our invention is to provide an efficient and neat stop-motion mechanism which will promptly effect the stopping of the loom upon the absence of the weft from its proper position as the lay beats up.

To the aforesaid purpose our invention consists in the novel and peculiar arrangement and constructionof the several parts of the mechanism, all as hereinafter fully described.

In the accompanying'drawings, illustrating our invention, Figure 1 is a plan view of our improved stopmotion, part of which is mounted on the lay of the loom and part on the breast-beam, the latter part being indicated in broken lines. Fig. 2 is an enlarged detail view of a portion of the stop-motion shown in side view; and Fig. 3 is a view of the parts shown in Fig. 2, the view being taken at right angles thereto. Fig. 4 is a plan view of the parts shown in Fig. 2. Fig. 5 is a side view of another form of cam used in the mechanism, together with the other adjacent parts.

In the said drawings like numbers of reference designate corresponding parts throughout. A i

Referring to the drawings, the number 6 designates the lay of the loom, and the broken lines 7 indicate the breast-beam. The swinging locking-dog 8 is provided with the bearings 9, which are journaled in the bracket l0, secured on the bed-plate 11. The detectorfork 12 is secured by means of the screw 13 to the locking-dog, the under face, 14, of which ings.

is formed inclined, and over this inclined face slides the cam 15, which serves to elevate the dog and raise the detector-fork into its highest position, so that the fork may clear the shuttle when passing thereunder. The detector-fork is disposed transversely of the lay` in which is formed the slot 33, which the fork may fall into in order to lower the dog sufficiently to look the cam 15, as hereinafter described. The cam 15 is pivoted at 1G to the 6,0 bed-plate 11, and is provided with the segmental slot 17, which works over the stud 18, fixed to the bed-plate.

The cam l5 is provided with a p'rojection or shoulder, 19, which is engaged by the locking-dog S, when the latter is permitted to fall into low position, through the absence of the weft and its consequent failure to vhold the attached detector-fork elevated, as shown in Figs. 2 and 3. In this position the dogSlocks 7o the cam 15 against moving in one direction.

The stop-motion rod 20 is hinged to the cam 15 by the bolt 21, and the other end of the rod .is passed loosely through the bracket 22, formed with slot 23, which is shown in broken lines. 'The extreme end of this rod is formed with an enlargement, 24, to prevent the rod Jfrom being withdrawn from the slot. The spring 25 is placed about the rod, and one end thereof abuts against the adjustable stop 26, 8o secured on the rod, while the other end of the spring bears against the slide or washer 27, which engages with one face of the bracket .Y

The shipper-bar 28 is Inounted in the hangers 29, which are fastened upon the under face of the breast-beam 7, and the bar is capable of being reciprocated endwise in its bear- One end of the shipper-bar engages the shipper-lever 30, (shown in cross-section in.

1,) and 31 is an adjustable stop, mounted 9o on the bar and designed to be engaged by the foot 24 of the rod 20 and pushed thereby sufficiently far to ship the driving-belt (not shown) in order to stop the loom, whenever the absence of the weft 32 (shown in Fig. 1) allows 95 the detector-fork to lower the dog S, so as to lock the cam 15, which then being fixed will push the rod 20 through the slot in the bracket 22, in an obvious Inanner, into engagement with the stop 31 as the lay moves forward. Ioo

1o which is moved by the motion oi' the lay because ot' the resistance ottered to the rod :20 by the spring 25. The dog thus escaping the projection on the eam, it eannotI lock the cam, so that the rod 2t) is not moved far enough to I5 engage the shipper-bar; but when the wet't 32 and adapted to engage the weft, the eam for is broken or is not in proper position the dog loeks the cam, and the beating up of the lay pushes the rod 2t) into engagement with the shipper-rod and stops the loom as above de- 2o scribed.

The bed-plate ll is to be fastened at a suitable place along the lay and upon the V["ace thereof opposite the breast-beam, as shown in Fig. l.

Having thus described our invention, we elaim as new and desire to seeure by Letters Patent-- a projection tor engaging the dog,whereby the lattermay lock the cam, a shipper-bar, and a stop-mot ion rod hinged by one end to the said eam t'or operating the latter and engaging by the other end the shipper-bar, and a fixed slotted braeket through the slot ot' which the other end ot' the said rod takes, the rod being provided with a spring to resist the motion imparted to the rod by the movement ot' the lay, substantially as and tor the purpose herein described.

ft. The eombination, as hereinbefore set forth, with the lay t'ormed with a slot; to reeeive the detector-t'ork, olf a swinginglookingdog and the detector-t'ork mounted thereon raising the dog and provided with a projection or shoulder by meansot' whieh the dog l may lock the cam, a shipper-rod provided with a stop, a stop-motion rod hinged by one end to the eam and (aigaging bythe other end the stop on the shipper-bar, a slotted bracket i tixed to a stationary pal't ot' the loom, and the end ot' the stop-motion rod loosely passing' through the slot ot' the bracket, a slide or washer working on the rod and abutting against the bracket, a stop tixed to the rod,

l. The eombilmtion, as hereinbefore set forth, with a swinging locking-dog and a dei 3o teetor-fork mounted thereon, ol a eam t'or elevating` the fork to its highest position, the said eam provided with means for engaging the loeking-dog when the fork detects the absence of the weft, lthe shippenbar, and the stop-motion rod provided with a spring and intermediate the said bar, and cam, whereby i ted braeket 22 t'or reeeiving the end ot' the the shipper-bar may be moved by the rod upon the loekingot' the cam by the loelzing-dog, substantially as and t'or the purpose herein deseribed.

2. The Combination, as hert'linbetore set forth, with the lay, ot' the swinging loekingdog and the deteetor-tork mounted thereon, a Cam for moving the dog so as to elevate the fork into its highest position and provided with a projeetion for engaging' the dog, whereby the dog may loek the cam, a shipper-bar for etli'eeting the shipping ot` the belt, and a stop-motion rod hinged to and operating the eam and engaging the shipper-bar when the cam is locked by the dog, and a spring mounted on said rod to resist the motion imparted to the rod by the movement of the lay, substantially as and forthepnrposeherein described.

3. The combination, as liereiiibetore set t'ortl1,with the lay, ot' the swinging locking'- dog and the detector-fork mounted thereon,

a eam for raising the dog and provided with and a spring intermediate the stop and the slide on the rod, substantially as and t'or the purpose herein deseribed.
