UNITED STATES PATENT OEEICEa GEORGE A. DRAPER, OF IIOFEDALE, MASSACHUSETTS, ASSIGNOR TO THE DRAPER COMPANY, OF SAME PLACE AND PORTLAND, MAINE.

LAY FOR LOlVlS.

SPECIFICATION forming part of Letters Patent No. 621,750, dated March 21, 1899. I' Application filed April 4, 1898. Serial No. 676.304. (No model.)

. T all whom it may con/cern:

Be it known that I, GEORGE A. DRAPEE, of Hopedale, county of Worcester, and State of Massachusetts, have invented an Improve- Without undue weight and having a continuous integral shuttle-raceway.

Other features of my invention will be hereinafter described, and particularly pointed4 out in the claims.

Figure l is a front elevation of a layembodying my invention. Fig. 2 is an enlarged transverse section thereof on the line Fig.

l; and Fig. 3 is a like view on the line 0c',

Fig. 1.

rThe body of the 'lay comprises a casting having a longitudinal depending web a, extending from end to end, and a horizontal forwardly-,extended flange c at the top of the web, forming a continuous shuttle-raceway, said flange having a transverse depression c2 at the point Vwhere lthe filling-fork grating bx is attached. The surface of the flange is suit.

ably milled to present a smooth path for the shuttle.

At the ends of the lay front and back plates 'are bolted to the flange to form the shuttleboxes B B', the flange being longitudinally slotted at ax, Fig. 3, for the picker-sticks P P.

Non-metallic wear members h at one end and h at the other end of the lay are bolted thereto beneath the flange and at the sides of the picker-stick slots to prevent the wear of the sticks by contact with the metal of the lay, said wear members being preferably made of wood.

Between the lay-swordsA the lay is shaped in section as shown at Fig. 2, an auxiliary web as, offset lfrom the main web a and conneoted thereto by a liange c4, being joined to the under side of the flange a', forming a trough-like seat back of and below the race- Way. In this seat are mounted two clamp members c c', the former shown as held be` tween the lianges a and c4 and abutting against the rearface of the auxiliary web a?, while the latter restson the flange d4, extended backwardly beyond the main web c at c5. -Theclamp member c has a seat c2 along its front upper corner for the bottom bar R of the reed RX, and the back upper corner of the member o is beveled at c3, on which the warp-threads in the lower plane of the shed rest.

Clamping bolts c extend through the clamp members o c' below the reed-bar and project through the auxiliary web a3, the threaded ends of ythe bolts having suitable nuts c5 thereon by which the member o is drawn tightly against the fixed member c to clamp the reed-bar R.

Suitable bearing-brackets d are bolted to the web a for the usual binder and protector rod dx, the lay herein shown having back binders.

This lay is adapted to be used in looms provided with filling-changing mechanism operated by or through a bunter on the lay, and I have shown the lay as having as an integral part thereof a bunterf, extending upward and forward from the front of the lay, near one end thereof.

Having fully described Imy invention, what I claim, and desire to secure by Letters Patent, is-L v l. A cast-metal lay having a longitudinal, horizontal flange forming a continuousrace'- way for the shuttle, a depending web, and an integral bunter extended forwardly from the web and flange, `substantially as described.

, 2. A cast-metal lay having a main longitu dinal depending web extended from one end to the other end, an integral lateral liange at the top thereof, forming a continuous shuttle-raceway and longitudinally slotted at the ends for the picker-sticks,-an auxiliary web offset from the main web, and a flange connecting them, forming a trough-like seat back of and below the raceway, combined with longitudinal non metallic wear members attached to the lay below the slots, substantially as described.

3. A cast=metal lay having a longitudinal depending web extended from one to the other end, a horizontal, forwardly-extended iiange Ico integral with the web and forming a continuous shuttle 1aceway, a second horizontal flange, and means mounted on Said flange to clamp the lower reed-bar to the lay, substantially as described.

4. A cast-metal lay having an integral, continuous shuttle-raceway longitudinally'slotted at its ends, and a projecting bunter forming an integral part of thelay, substantially as described.

5. A castdnetal lay having a longitudinal depending web extended from one to the other end, a horizontal, forwardly-extended flange integral with the web and forming a continuous shuttle-raoeway, a second flange, and a web connecting said ilanges,fo11ning a troughlike scat at the rear of and below the raceway, clamping members mounted therein to engage the lower reed-bar, and means to adjust said clamping members, substantially as described.

6. A cast-1netal lay having a longitudinal depending web and two connected horizontal'
