Specification of Letters Patent.

Patented Sept. 9, 1913.

T 0 (ZZZ whom it may concern Be it known that'I, ROBERT SOHREY, a. citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented for controlling the movement-of the reed and locking the reed j against accidental movement. 7

A further object is to improve upon the construction disclosed in Patent No. 1,040,778 granted to me' October 8, 1912.

. With these and other objects in view, the invention consists in certain novel features .of construction and combinations and arrangements of parts as will be more fully hereinafter "described and pointed out in the claims. V

In theaccompanying drawings: Figure 1 is a vertical section with all parts of the loom removed except such as are necessary to illustrate my inven Fig. 2 is a fragmentary view in. plan showing the lay in one extreme position. Fig. 3 is a fragmentary view in section on an enlarged scale showing one position of the reed on the forward beat of the lay. Fig. 4 is a similar view showing the other extreme position of the reed on the forward beat of the lay, and

Fig. 5 is a fragmentary rear elevation of the lower bar of the reed.

1 represents the frame of a loom such as commonly employed. in the -weaving of towels, wherein the loom utilizes the well known terry motion.

2 represents the ordinary vibrators, 3 the ordinary pivoted lay having parallel trans verse bars 4 and 5 between which reed 6 is located, and 7 is the ordinary transverse supporting, bar at the forward end of frame 1.

As above stated, this invention is an improvement upon the construction illustrated in my prior patent in which I provide on the inner face of the bar or batten 7, a guide 8 secured by bolts 9 and nuts 10. This guide 8 is adapted to receive two blocks 11 which are of the peculiar shape shown in Figs. 3 and 4. That is to say, that they shaft 26 supported in brackets 27.

have a rectangular portion 12 which fits in the guide 9 and is locked in the guide against movement except longitudinally of the guide. The main portions 13 of said blocks project above the guide and lie in the path of movement of pivoted fingers 14 which are pivotally connected to the lower bar 23 of reed 6. Thislower bar 23 of reed 6 is movable on the lower bar 5 of the lay, and is held in its normal forward position by curved fingers 25 secured to a transverse The shaft 26 has a crank arm 28 which is connected by a coiled spring 29 with the lay, so that an elastic forward pressure is alwcpys had upon the lower bar 23 of the ree The blocks 11 are connected by a rod 15 which compels them to move together. A coiled spring 16 is connected at one end to one of the blocks 11, and at its other end to a fixed pin 17 which normally holds the blocks 11 out of the path of movement of fingers 14. The other block 11 is connected to a cable 18 or other suitable flexible connecting device which is passed around pulleys 19, 20, and 21, and at its free end is provided with a link 22 to engage over one of the vibrators 2, so that the motion of the vibrator will cause the blocks 11 to be movedlongitudinally of batten 7 andinto the path of movement of the fingers 14.

The fingers 14 are pivotally connected to plates 30 recessed in the back of bar 23, and said fingers project through slots 31 in said bar 23, and at their free ends are provided with beveled surfaces 32 adapted to be engaged by the blocks 11 and caused to elevate. The lower face of eachrfinger 14 adjacent its free end is provided with a shoulder 33 which normally lies in front of bar 5 to securely lock the reed against accidental rearward movement.

Before the fingers 14 can be moved rearwardly, it is necessary to first elevate them, and this is accomplished by the engagement of the beveled surface 32 with the blocks 11. Hence, when the blocks 11 are moved into position to be engaged by the fingers 14, the first operation will be to elevate the free ends of the fingers 14, so that the shoulders 33 are out of engagement with the front face of bar 5. A continued movement of the lay toward the blocks brings shoulders 34 on the fingers into contact with the blocks described without departing from my in vention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the sp rit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

V 1. The combination with the lay of a loom, a reed on said lay, fingers pivotally 0on nected to the reed and having shoulders thereon normally engaging the lay andholding the reed against independent movement, said fingers at their extreme outer ends having beveled lower faces, and movable blocks adapted to be engaged by said beveled faces to life the fingers out of locked position and cause the reed to be moved rearwardly.

2. The combination with a lay of aloom anda reed thereon, of fingers pivota-lly secured to the reed and adapted to'lock the reed against movement, and means for moving the fingers out of locked position and moving the reed through the medium of said fingers, substantially as described.

3; The combination with the lay of a loom, and a reed thereon, of fingers pivotally connected to the reed, and normally engaging the lay to hold the reed against rearward movement, and means adapted to be moved into position to be. engaged by the fingers to first move the fingers out oflocked engagement with the lay and then move the reed on the lay,substantially as described.

4. The combination with the lay of a loom, and a reed mounted thereon, said reed having a lower bar movable transversely on a fixed bar of the lay and having slots therein, of fingers positioned in the slots in the reed bar and pivotally connected at one end to said bar, shoulders on said fingers adapted to engage a ainst the outer face of the lay bar and hold the reed bar againstrearward movement, and means'for first elevating the fingersout of flocked engagement with the lay bar and then moving the. reed rear wardly, substantially as described.

5. The "combination with the lay of a 100m, and are'ed. mountedthereon, said I'GGCl'hZhV'. ing a lower bar movable transverselyoni a fixed bar of the lay andhaving slots therein, of fingers positioned inthe slots in the reed bar and pivotally connected at one end to said. bar, shoulders on said fingers adapted to engage against the outer face of "the lay bar and'holdthe reed bar against rearward 1novemenhsaid fingers at their extreme outer ends having beveled lower faces, and shoulders at the inner ends of said beveled faces, 7

and movable blocks adapted to be engaged by said beveled faces to. first lift the pivoted fingers out of lockedengagementwith the lay, and then engaged by said last-mentioned shoulders to move 'the"reed -rear;

u rdly, substantially as described. 6. The combination withthe lay of aloom, a reed on said lay, fingers pivotally connected to the reed and having shoulders thereon normally engaging the layand holding the reed against independent movement, said fingers at theirlextremeouter ends having beveled lower/faces, said fingers having shoulders at the inner ends of the beveled faces, andmovableblocks adapted to be en gaged by said beveled faces to lift the fingers out of locked position and then engaged by the last-mentioned shoulders to move the reed rearwardly, substantially as described.

In testimony whereof I have'signed my name to this specification in the presence oftwo subscribing witnesses.
