ELIJAH HALL, OF ROCHESTER, NEWv YORK.
POWER-LOOM.
Specification of Letters Patent No.
To all 'whom 25 may concern Be it known that I, ELIJAH HALL, of the city of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Power- Looms; and I do hereby declare that the following is a full, clear, and exact descrip` tion of the same, reference being had to the annexed dra-wings, forming part of this specification, in which- Figure l, is a vertical section of a power loom in a plane parallel with the warp. Fig. 2, is another vertical section transversely to the warp showing a back view of the lay, reed and their appendages. Fig. 8, shows one of the bolts for securing the reed detached from the loom.
Similar letters of reference indicate corresponding parts in the several figures.
This invention consists in certain means by which the reed is secured rigidly in the lay at the time of beating up the filling and also during the whole time that should be occupied by the flight of the shuttle, but from the time when the shuttle should have entered the shuttle box till the lay has nearly arrived at the end of its forward movement is liberated to such an extent that it will be caused to liberate itself entirely and swing back if the shuttle should be obstructed in, or fail to pass entirely through the warp, and will thereby prevent injury to t-he cloth which would otherwise occur.
To enable others skilled in the art to make and use my invention, I will proceed t0 describe its construction and operation.
A, is the lay which is driven in the usual manner by cranks O, and connecting rods B, B.
D, is the reed which is hung by its top rail a, in the lay cap o, in such a way that if the lower rail a', were free it might swing back. The lower rail a', of the reed fits in a suitable recess in the back of the lay and is held there by means of a baro, which is connected by two arms d, d, with a small shaft e, fitted to suitable bearings under the lay. This shaft has a spiral spring f, applied to it, in such amanner as to hold the bar c, up against the back of the lower rail of the reed with suflicient firmness to keep the reed steady in its place when it is not beating up the filling or the shuttle is not passing in front of it, but as to allow the reed to swing back, and force back the bar c, in case of the shuttle being arrested in the 14,237, dated February 12, 1856.
warp and struck up by the reed. When this occurs the lower rail of the reed pushes back the bar 0, and passes it, and after it has passed, the bar c, is thrown forward by the spring, leaving the reed hanging quite free behind it, so that as t-he lay continues to beat up no injury will be done before the weaver has time to throw the loom out of gear.
The devices thus far described are substantially like devices which are described in the specification of Letters Patent granted to me Sept. 14th, 1850, and are only described here to explain my new invent-ion, the object of which is to lock the reed securely in the lay during the flight of the shuttle and at the time the filling is beaten up but to partly liberate it from the time the lay arrives at such a point in its forward motion that the shuttle can be caught between the reed and the beaten up filling at which time the shuttle should have entered the box t-ill just before the forward movement of the lay terminates so that it may swing back in case of the shutt-le failing -to enter the box at the proper time. This is effected by means of two upright sliding bolts g, g, working in st-aples it, t, and i, t', secured to the back of the lay and of its swords y', j. One of these bolts is shown detached, see Fig. 3. The bolts are connected at their lower ends by pivots p, p, light rods la, 7c, and pivots g, g, to the connecting rods O, C, at some distance behind the point n, of attachment to the lay. These rods 7c, 7c, run upward in an oblique direction from the bolts to the connecting rods Ci, C. The vibrating movement of the connecting rods produced by the driving cranks, imparts through the rods le, 7c, an upward and downward movement to the bolts causing them to commence rising just before the lay commences to recede, and commence falling just before the lay commences to advance, the effect of which is that the bar c, is rigidly secured or locked by the upper ends of the bolts during the entire movement of the lay except from that point in its advance when t-he reed arrives near enough to the filling point t-o be obstructed by the shuttle being left in the warp, till its forward movement has nearly terminated, during which interval t-he upper ends of the bolts are drawn below the bar c, and the reed is unlocked, but just before the forward movement of the lay terminates the points of the bolts are raised high enough to catch the bar 0. This movement of the bolt is illustrated in F ig. l, where the lay is shown in two posit-ions, the position represented in red outline being when the lay has just reached the point in its movement where the shuttle should have passed into its box, and the bolt just having been drawn below the bottom of the bar 0, and the position shown in black outline being, when the lay has beaten up and the points of the bolts have just risen high enough to catch and secure the reed. The bolts continue rising as the lay recedes until just as its receding movement is about to terminate when they commence their downward movement which continues till the lay has nearly finished its forward movement.
This method of liberating and securing the reed is a substitute for the protector, which I consider to be the greatest obstacle to thevery rapid operation of the power loom, and this possesses the advantage over the protector of allowing the loom to be driven at speed which is unlimited except by the operation of other parts.
Vhat I claim as my invention, and desire to secure by Letters Patent, is-
Locking and unlocking the reed by means of sliding bolts g, g, applied to the back of the lay behind the reed, and operated by connections with the connecting rods B, B, by which the lay is driven, substantially as herein described.
