LOOM.

SPECIFICATION forming part of Letters Patent No. 640,706, dated anuary 2, 1900. Application filed February 2'7, 1899. Serial No. 706,956. N mo l-l To all whom, it may concern:

Be it known that we, GUSTAV SOHAEFER and FRIEDRICH HINKEL, of Clinton, county of Worcester, State of Massachusetts, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings,is a specification, like letters and figures on the drawings representing like parts.

In looms as now commonly constructed it is customary to stop the loom automatically whenever the shuttle is not present, as it should be, in the shuttle-box.

Herein we have provided a loom with means whereby whenever the shuttle is absent from the box in which it should be at either end of the lay the loom will be stopped, and so, also, should two boxes occupying a position at the level of the race of the opposite ends of the lay each have a shuttle then the loom will be automatically stopped.

In accordance with our invention we combine with the lay having shuttle-boxes at its opposite ends and carrying a hunter having two acting portions two binder-shafts, each having at one end a binder-finger to act on a binder of a shuttle-box and at its other end a projection, the projection of one shaft entering a hole at one end of the bunter-rest, while the projection of the other binder-shaft enters a slot in the said hunter-rest, the hunterrest being shown as convexed at its top. With the use of these devices the loom may be stopped whenever a shuttle is absent from the box in which it should lie at either end of the lay, and so, also, should two boxes occupying a position at the level of the race of the lay at opposite ends thereof have a shuttle.

Figure l, in partial section, shows a sufficient part of a loom with our improvements added to enable our invention to be understood. Fig. 2 shows the dagger-rest detached.

Fig. 2 shows the double-acting bunter detached and enlarged. Fig. 3 is a partial front elevation of a loom with our improvements added, the drawing showing chiefly parts of the lay, usual shuttle-boxes, and parts carried by the lay, together with one corner of the loom-frame and part of the breast-beam, the breast-beam and lay being broken out to save space on the drawings; and Fig. et'is a top or plan view of the parts shown in Fig. 3, it representing, however, more of the breastbeam.

The loom-frame A, its breast-beam A, the shipper-holding plate A extended from the loom side and having a slot'a provided with a side notch in which may be held the shipper-handle B,'the knock-off lever B, pivoted at B at the under side of the breast-beam, the cam --shaft B having an attached toothed gear B, which meshes with a smaller gear B fast on the crank orlay shaft 13 united with l the lay O by connecting-rods O, the lay-shaft C the shifting shuttle-boxes C at one side of the loom, each shuttle-box having a suitable binder a, acted upon by a spring a to normally press the binder toward the shuttle in a cell of the shuttle-box, and the binder b at the opposite end of the lay, pivoted at b, the guide-plate 11*, forming part of the shuttlebox, at the right-hand end of the lay, and the shuttle b are and may be all as common in usual looms.

We have provided the lay at its under side with suitable ears or boxes 2 3 4 5. boxes 2 3 contain a binder-shaft 61, having at one end a binder-finger d,whichis normally kept pressed against the free end of the binder b by a suitable spring 01 surrounding said shaft and connected at one end to a collar thereon, the opposite end of the spring contacting with the ear 2 or other part of the lay.

to a collar 6 fast on said shaft, while the other end contacts with some fixed part of the lay. These two shafts are connected by a daggerrest f, the shape of which is best shown in Fig. 2. This link is pivotally mounted at one end upon the projection 6 while at its other end it has a slot 8, which is entered by the projection (i a suitable cotter-pin being passed The through a hole in said projection to retain the link upon said projection.

The lay has attached to it a casting or block g, having a pivot or stud g, upon which is mounted a double-acting hunter composed of an arm 9 having projecting, as herein shown, from its under side a hook 9 said arm and hook being best shown in Fig. 2. The bunter is acted upon near its pivot by a spring g which normally serves to depress the acting front end of the hunter.

To the under side of the breast-beam We have attached astand h, having a depending apron 7t, slotted at 71 said slot receiving in it an adjustable stud h upon which is mounted a lever h having adjustably connected at its ing, stud 72 lower end and extended therefrom a stud h The upper end of this lever hstands normally close to and bears against the end 10 of the knock-01f lever b, and the head 10 of the said knock-01f lever is notched, as best shown in Fig 1, where the same is shown by looking at the loom from the left of the dotted line :c, Figs. 2 and 3. Viewing Fig. 1,'it will be seen that there is a space between the grooved edge of the knock-off lever and the project- When the shuttle is in its proper position I in one of the shuttle-boxes opposite the level of the race of the lay, whichever box the shuttle is in will cause the binder of the box having the shuttle to turn the rock-shaft d or e and depress the projection d or c such depression of either one of said projections singly lowering the dagger-rest f, so that the double-acting binder moves backward and forward in the space between the end 10 of the knock-0E lever and the projection if, and consequently the knock-elf lever is not moved. Should, however, the shuttle be absent from either box, then the spring (2 or e acting upon the shafts d or 6, will turn the binderiinger d or e inwardly, moving the binder b or a into the shuttle-box, such movement causing whichever projection d or e is moved to lift the dagger-rest f, so that it, acting by its projection f against the under side of the hunter, will lift the same, so that in case a shuttle be absent from both boxes the end 12 of the upper part of the hunter will meet the end 10 of the knock-oh? lever and turn it to release the shipper-handle from its usual notch in the holding-plate a Should the shuttle-boxes opposite the level of the race of the lay at each end of the reed have a shuttle in them, then in suchcase there is a fault and the binders of both of said boxes, held out by the shuttles in them, will act to turn the binder-fingers outwardly, lowering both the projections d and c which move downwardly the rest f, permitting the spring 9 acting with the gravity of the hunter, to lower the hunter so that its hooked part 9! in the back stroke of the lay will catch the projection k turn the lever h in the direction of the arrow just below it, Fig. l, causing the upper end of said lever to meet the end 10 of the knock-off lever, and release the shipper-handle from the loom. In this way it will be understood that the lay will be stopped automatically whenever a shuttle is absent from the box in which it should appear, and also whenever two shuttles are presented in opposite boxes where under ordinary circu instances there should be but one shuttle, and it is especially this last action of stopping the loom when there is a shuttle in opposite boxes at the end of the lay that we believe our invention to be essentially new and novel and, never before known.

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

1. A lay having shuttle-boxes at opposite ends thereof and provided with a bu nter, two binder-shafts carried by the lay, each having at its outer end a binder-finger to act on a binder of a shuttle-box, and at its inner end a projection, and a hunter-rest having one end pivoted to one of said projections and the other end joined to the other projection by a pin-and-slot connection, combined with a shipper-handle and means adapted to be acted upon by said bunter in either of its extreme positions to dislodge the shipper-handle and stop the loom whenever a shuttle is absent from either box in which it should be present, and whenever two boxes at the level of the race each have a shuttle, said bunter occupying a third position intermediate its extreme positions whenever the shuttles are in their correct boxes.

2. A lay having a shuttle-box at opposite ends thereof and provided with a hunter having two acting positions; two binder-shafts carried by the lay, each having at its outer end a binder-finger. to act on a binder of a shuttle-box, and at its inner end a projection, and a hunter-rest having at one end a hole and at its opposite end a slot, and provided centrally with a rest on which the hunter is supported, one of said projections entering the hole and the other the slot in the ends of the hunter-rest; combined with a shipper-handle and means adapted to be acted upon by said hunter in either of its extreme positions to dislodge the shipper-handle and stop the loom whenever a shuttle is absent from both boxes at opposite sides of the lay, and whenever both boxes at opposite sides of the lay on a level with the race each contain a shuttle, said hunter occupyinga third position intermediate its extreme positions whenevera shut tle is in one of the boxes at the level of the race, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses. 1
