STOP- MOTION-FOR LOOMS.

SPECIFICATION forming part of Letters Patent No, 352,340, dated November 9, 1886.

Application filed June 26, 1885. Serial No. 169,823. (No model.)

To all whom it may concern.-

Be it known that we, BENJAMIN F. MEYER, of the city and county of Camden, State ofNew Jersey, and MAGNUS KOHLER, of the city and 5 county ofPhiladelphia, State of Pennsylvania,

both citizens of the United States, have invented a new and useful Improvement in Stop- Motions for Looms, which improvement is fully set forth in the following specification 1 and accompanying drawings, in which I Figure 1 represents a front view of a portion of a loom embodying our invention. Fig. 2 represents a side elevation of a portion thereof. Fig. 3 represents a portion of Fig. 2, the parts 1 thereof being in different positions. Fig. 4 represents a horizontal section in line a: m, Fig. 1. Fig. 5 represents a detached view of the parts which raise the grid-plate of the loom.

Similar letters of reference indicate corresponding parts infthe several figures.

Our invention consists of means for automatically stopping a box-motion loom in the event of the failure of a shuttle to enter its box, as will be hereinafter set forth.

Referring to the drawings, A represents the frame ofa loom, and B the lay thereof, which is operated by the crank-shaft O and connecting-rods 0*, as usual.

D represents a grid plate, which, located at 0 the top of the lay, is mounted on a rock-shaft,

D", having connected with it an arm, E, the rock-shaft being mounted in bearings on the rear of the lay.

To the side of the lay is pivoted a dog, F,

r 5 which is of an angular form, and has a hook or nose at the lower end of its vertical limb. To the upper or horizontal limb of said dog is pivoted a rising-and-falling bar, G, which rises i'rom said limb, and has its upper end below 0 the plate ,D. To the bar G is pivoted an angular or L-shaped piece, H, which is pivoted by a link or a strap, J, to the lower end of the arm E. v

To the side of thelay is pivoted a feeler, K, which in the present case is formed of front and rear parts, both connected with a rockshaft which is mounted on the lay. The front part carries a pivoted nose, L, having a contact-face composed of two surfaces, as L L as shown, and the rear or heel end overhangs the horizontal limb of the angular piece H, said feeler receiving rising and falling motions by means of a double-inclined piece, 'M, and spring N, said piece M being secured to the frame of the loom, and so located below the feeler that as the lay advances the nose Lrides upon theinclined rear side of the same, thereby raising the forward end of the feeler K. On the return motion the nose, being free to swing in the opposite direction, rides freely over the double incline, the spring N being connected with it and the lay of the loom 'for lowering the front end of the feeler, and consequently elevating the heel thereof. The descending motion of the front end of the feelerislimited 6 I by a stop, K, projecting upward on said feeler, and which abuts against ashoulder on the adjacent part of the lay.

P represents a rising-and-falling bar having a nose, Q, at its upper end, the same being adapted to be engaged by the nose or hook of the dog F when the bar P is at its highest position, said bar having at its lower end a pin, P, which is guided in avertic al slot, P, in the side of the lay of the loom.

To the lower end of the bar is pivoted a rod,

R, which rises therefrom and has its upper end pivoted to a curved or bent lever, S, whichis pivoted tothe frame of the loom, and has its outer and upper limb, which extends verti 8o cally, formed with two stops or lugs, S, which embrace opposite sides of the shipper-leverT of the loom.

When the loom is in motion, the plate D is raised in theusual way by a cam, O, on the 8 rotary shaft 0, operating an arm, 0 pivoted to the frame, the front end of said arm being in contact with and bearing against a lever, 0 secured to a rock-shaft, 0 mounted on the I lay, and having a limb, C, carryinga projection, 0, adapted to strike the grid and elevate the same. The plate D is held up until the shuttle reaches its box, after which said plate D drops and returns to its normal position, which is somewhat elevated, it being there sus- 9 5 tained by the weft thread or yarn when pres cut, as shown in Fig. 2, it.being noticed that the rising of the grid-plate occurs when the shuttle is to be thrown. The feeler K oscillates during the motions of the lay, the nose 10o L, on the forward motion of the lay, being held rigid against the feeler, owing to the shoulder L of the nose resting against said feeler, and yielding on the return motion. Vhen the plate D falls, after being raised by the cam O and connecting devices,and rests on a weft-thread, as shown in Fig. 2, the horizontal limb of the piece H is turned back by the armE and link J. Should, however, the shuttle fail to enter its box, it will project from the latter and remain under the plate, causing the latter to remain elevated and the piece H to be held in its advanced position, (shown in Fig. 3,) so that when the feeler rises on the inclined piece M its heel is depressed against the lower limb of said piece H, thus lowering said piece, whereby the dog Fis moved, so that its nose leaves the nose of the sliding bar P, and as the latter is no longer controlled by the dog it drops, and with it the rod It, the same being assisted by a spring, R, connected with the said rod and the frame of theloom. This moves the lever S, whereby the shipper-lever T is thrown out of its usual notch, and the shipper lever spring then shifts the lever, whereby the power-belt is'also shifted, the ef feet of which is the immediate stoppage of the loom. As soon as the defect is remedied the shipper-lever is returned by hand to its notch, thus starting the loom, and as the lever enters its notch it' strikes the left hand nose S, thus operating the lever S, raising the rod R, and consequently the bar P, the dog F then engaging with the nose of said bar P, this operation being preceded by advancing the lay sufficientlyt-o allow the nose L to clear the highest point of the inclined piece M, whereby the piece H is releasedoftheholding power of the heel of the feeler, so that the bar G may be raised and the dog Frestored to its normal position, the parts thus being reset, after which the operation of the several parts is similar to that hereinbefore set forth.

Should the yarn or thread break, the plate D, previously resting thereon, drops on the bar G and lowers the same, the effect of which is the operation of the dog F andrelease of the bar P, and consequent stoppage of the loom, similar to that accomplished by the failure of the shuttle to pass into its box at the proper time.

In resetting the shipping-lever, the right hand lug or stop S on the lever S strikes the shipping-lever, and thus limits the elevation of the rear arm of said levers and prevents an abrupt and extensive upward motion being imparted to the bar P.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A lay, in combination with the feeler K, pivotally secured to said lay, the nose L, piv otally secured to said feeler, the double-inclined piece M, the grid-plate D, the rockshaft D, having bearings in the rear of the lay, means, substantially as described, for imparting a rising-and-falling motionto said grid-plate D, the bar G, the arm E, connected to the rock-shaft D the angular piece H, the link J, pivotally connecting said arm E and angular piece H, the pawl F, the shippinglever T, and mechanism, substantially as described, intermediate of said pawl F and said shipper T, whereby said shipping-lever is shifted, all substantially as described. I
