WILLIAM MCMIOHAEL, OF l/VOONSOCKE'I, RHODE ISLAND, ASSIGNOR TO THE IVOONSOOKET MACHINE AND PRESS COMPANY, OF SAME PLACE.

LOOSE-REED MOTION FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 533,314, dated January 29, 1 895.

Application iiled March 30,1894.

To @ZZ whom it may concern:

Beit known that I, WILLIAM MoMIoHAEL, of Woonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in `Loose-Reed Motions for Looms, of which the following is a specification.

This invention has relation to socalled loose-reed motions for looms, that is, contrivances whereby,.in case of alodgment of a shuttle in the shed, or other similar happening, the reed will be allowed to yield or swing back, preventing a smash It is the object of my invention to provide improvements in this class of devices which will simplify their construction and render them certain in their operation.

Theinvention consists of theimprovements which I will now proceed to describe in detail and point out in the appended claims.

Reference is to be had to the drawings hereto annexed and forminga part of this specification, as also the letters of reference marked on the drawings, the same letters designating the same parts or features, as the case may be, wherever they occur.

Of the drawings-Figure lis a sectional end view of the breast-beam, lay and reed of a loom equipped with my improvements, the reed being in normal position. Fig. 2 is a similar view, omitting the breast-beam, and some of its connections, and showing the reed as unlocked, the lay having moved forward. Fig. 3 is a top or plan View of a part of what is shown in Fig. l, the lay being moved forward. Fig. I is a front view, partially in section, of the part of the lay shown in Fig. 3, the section being taken on the line 4 4. of the last-mentioned figure. Fig. 5 is a perspective view of one of the reed locking plates. Fig. 6 is a front view `of one of the locking plates and its guides, showing the locked position of the plate, the bolt being represented in section.

In the drawings-a designates the breastbeam, b, is the lay, and c, is the reed of a loom.

The upper bar, d, of the reed is pivotally or hingedly connected with its support so that it may be sw ung on the said bar, say from the position in which it isshown in Fig. 1, to that Serial No. 505,697. (No model.)

in which it is represented in Fig. 2, the position in Fig. l being the normal and that in Fig. Zthe unlocked or released and swungback position.

e is the holding-bar between which and the lay proper the lower bar d of the reed is held when the latter is in normal position.

The holding bar is supported so that it may be locked in place and rigidly held to maintain the reed in normal position when the latter acts to beat up the weft, and yet be released so as to be moved back and release the lower bar of the reed to permit it to swing backward.

The holding-bar is kept in normal position by means of a spring or springs,f, free ends of which bear lightly thereagainst with suficient force to maintain it in place when unlocked, the springs at their opposite ends being secured to some convenient part of the frame-work of the machine;` and also by a spring-pressed rod or rods connected with the breast-beam, and through the medium of suitable eontrivances with the locking means of the holding-bar.

In all instances when the lay is back the holding-bar will be unlocked, though yet maintained in normal position by the springs, f, which bear against it, the bar is unlocked and the reed free to swing against the yielding resistance of the springsfduringtherst part of the forward movementof the lay; but as thev lay advances still farther to beat up the weft, the holdin g-bar will be rigidly locked in place by the action of the spring-pressed rod upon the locking devices. This arrangement is provided in order that in case a shuttle becomes lodged in the shed the reed may bereleased and allowed to swing back as the V lay starts forward and the reed comes in contact with the shuttle,and so avoid asmash^.

Referring to the drawings, g, is the beforementioned spring-pressed rod, the inner end of which is pivot-ally connected with an ear,

h, on one of the locking plates t'. (See Fig. 4.) 95

The latter is adapted to slide and be guided in a plate, j, connected to the forward face or side of the lay, b. The rod, g, at its outer end is arranged to move in a block or piece, k, swiveled in a bracket, Z, connected to the IOO under side of the breast-beam, a. Between the block, k, and a collar, fm, fixed on the said rod, g, there is interposed a spring, at.

There are a plurality of locking-plates, t,

on the front face of the lay, and said lockingplates are connected by links o attached to the ears, p, as shown, so that when one plate is moved the balance must -be moved in unison therewith. Each'locking-plate,1l, is provided with an elongated slot, q, through which passes a bolt, r, the forward part of the backward end of which is connected with the holding-bar, e. The forward end of-the bolt, fr, is provided with a nut or head, s, and one part of the slot, q, is widened so as to permit the head of the bolt to pass therethrough, while the other part of the slot is narrower, so that while the bolt may move-longitudinally therein the head thereof cannot pass through it.

The lay is counter-sunk, as at t, so as to permit the head of the bolt, 1, to pass into the said counter-sink, in case of necessity.

In the operation of the invention, when the shed is unobstructed, the lay will move backward and forward with its usual functions, and with the parts in the position in which they are represented in Fig. l, but should a shuttle become lodged in the shed, as the reed is moved forward, it will be resisted, and the head, s, of the bolt, r, being in the widened part of the slot, q, the said bolt and holdingbar will be moved back against the stress of the spring,f, as shown in Fig. '2, the head, s,

of the bolt passing into the counter-sink, t,

and the reed swinging back from normal position. When there is no obstruction in the shed, when the lay moves forward, the inner end ofthe rod, g, by reason of it moving in the path of a circle, will move the lockingplates, 1', so that the shank of the bolt, r, will enter the narrow portion of the slot, q, as shown in Fig. 6, and so prevent the head of the bolt from moving through the same, and in this Way lock the parts and hold the reed rigidly in place. When the shank of the bolt moves into the narrow part of the slot, q, the rod, g, will still be allowed to yield longitudinally against the force of the spring, fn. In

this way a very efficient loose-reed motion is 5 provided and one that is at all times certain in its operation.

Having thus explained thenature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made, or all ofthe modes of its use, it is declared that what-is claimed isl. In a loose-reed motion for looms, in combination, a pivoted reed, la lay, a holding-bar mounted upon said lay, a spring arranged to act upon said bar, a breast beam, a springpressed rod connected therewith, and means joining said rod with said holding-bar.

2. In a loose-reed motion for looms, in combination, a pivoted reed, a lay, a holding-bar, springs for engaging said bar, bolts connecting said bar with sliding plates upon opposite sides of said lay, a breast beam, and a springpressed rod connecting said plates with said breast beam.

3. In a loose-reed motion for looms, in combination, a pivoted reed, a lay, a movable holding-har mounted thereon, springs for engaging said bar, sliding plates uponthe front of said vments on opposite ends for engaging the plates, a breast beam, and a spring-pressed rod connecting said beam and plates.

In testimony whereof I have signed my name to this specilication, in the presence of Atwo subscribing witnesses, this 27th day of March, A. D.l1894.

WILLIAM MOMIGI-IAEL.
