LAY rFon Looms.

Be itknown that'L-WILLIAM WATTin, .a citizen of' the United States, residing at VVorcesten inthe county of l/Vorcester and metal barforming the top and the front of State of Massachusetts, have invented certain new and `useful Improvements in Lays for Looms, ,ofrwhichr the following is a speci-l lcation. f, f Y

My inventionfrelatesto the lay of a loom, and particularlyfto ala of the type shown and described in my S, Letters Patent,

No. 7s9,943.- y

The objectfof myvinvention is to improve yupon the construction of ythe lay shown and described ink said patent, kand to rovide a lay of increased strength and rigidity, and particularly adapted'for heavy looms, as duck looms.y i i.

In my improved construction, l combine with'the wood beam of the lay, and the angle the lay, a Tk sha ed metal bar, locatedat the rear of the lay lbeam, `and extending on the lower surfaceoi the lay beam at the rear part thereof, rand also on ythe back of the lay beam, and also forming ashelfor support for a bar preferablyoi:l woodgat the rear of the lay, upon which' is supported alongitudinally extending metal bar forming a back stay for the lower part 0f the reed. l

I have only showninthe drawing a detached partfof the lay of a loom embodying my improvements, lsu'rlicient'to enable those skilled in the art to' understand the construction and operation thereof; 1 :i .y

kReferring tothe 'drawingFigu're 1 is a plan view of a layembodyingmy improvements,`looking"in the direction of arrow a,

' Fig. 2, and showing at ythe left some parts not shown in Fig. 2, which "parts are partially vbroken away to show the parts otherwise concealed. Fig. 2 is a front view of the parts shown at the right in Fig. 1, looking in the direction of arrow @same figure. Fig. 3 is a section, online 3,3, Fig. l, looking in the direction of arrow '6,same ligure, and Show- .ing Some parts broken 'awayin Fig. 1.

In the accompanying drawing, 1 is the lay Sword, having the horizontally extending plate 1 on its upper end which forms a support for the several parts of the lay beam. 1 is the horn of the lay, to which, and to the front up er f art of the lay, is secured the yflaring s utt e `box ymouth 2, having at its Specification of Letters Patent. yApplicationirledillarch'1.2, 1908.

lower part rearward projections 2 for the connector to the crank shaft, not shown.

Supported upon the shelf or extension 1 of the lay sword 1 of the loom, and extending in the direction of the length` of the lay, is in this instance a wood beam 3. Extending upon the front and u er side of the wood ar 1, or angle Shape in cross section, and forming the upper surface or race-way 4 ofthe lay, and also the front side of the lay.

out, as shown at 3 in Fig. 3, for the bottom of the reed 5.

Extending upon the front vertical edge of the cut out portion 3". is preferably a thin metal strip 6, secured to the beam 3. The lower rear part of the beam 3 is cut out to receive one side or liange 7 on the horizontally extending T shaped rigid/metal bar 7;

said side 7 forms the lower rear surface of the lay beam, see Fig. 3. The vertically extending portion 7 of theT shaped metal bar 7 extends upon the rear of the beam 3 and forms the rear side thereof. The other side or flange 7 of theT shaped metal bar 7 extends rearwardly from the lay beam, and forms a support or shelflor a bar 3, preferablymade or wood. Upontheupperside oi' the bar 8 and of the vertically extending part 7 of theT shaped metal bar 7 extends a bar 9,

preferably made of metal, and recessed upon its under Side, as shown at 9, Fig. 3, to receive the hooked end 10 on a horizontally extending bolt 10, which extends through a hole in the beam 3 and the front side of the angle metal bar/1, and is drawn up to secure the bar 9, by a nut 11. The bar 9 forms the back stay for the lower part ofthe reed 5, and is readily attached after the other parts of the lay are assembled, by means of the hooked end bolts 10, and` drawn toward the front of the lay, to hold the lower part of the reed 5, by screwing up the nuts l10n the bolts 10.

The metal angle shaped bar 4 is secured upon the beam 3 and to theT shaped metal bar 7, preferablyby a series of bolts 12, which extend through holes in the beam 3, and have their headed ends 12 upon the back side of the vertically extending part 7 of the T shaped metal bar 7, and a nut 13 secured upon their outer threaded ends.

Vertically extending bolts 14, with their The upper rear surface' of the beam 3 is preferably recessed or cutl heads countersunlr in the horizontally extending a rtl of the angle metal bar 4, and passing t rough holes in the beam 3, and having nuts 15 on their lower ends, secure in this instance the horizontally extending flange 7 of theT shaped metal bar 7 to the beam 3.

Vertically extending bolts 16, see Fig. 1, having their heads 16 extending in recesses in the rear upper part of the beam 3, and passing through openings in said part and in the side or iiange 7 of theT shaped metal bar 7, with nuts 17 on their ends, see Fig. 3, secure theT shaped metal bar to the rear part of the beam 3.

The bar 8 is preferably secured to the rear part of the beam 3 by screws 18, which extend through openings in said bar 8, and in the vertically extending part 7 of the T shaped metal bar 7, and into the rear part of the beam 3, see Fig. l.

From the above description in connection with the drawing, the advantages of my improvements in lay beam will be readily appreciated by those skilled in the art.

I provide the wood core or center of the lay beam, in case a wood beam center is used, with a metal top and front, extending the full length of the lay beam, and I also provide ythe rear part of the beam 3 with ametal bottom and rear side, and in addition provide a shelf or support for a bar at the rear of the lay beam, upon which is supported the detachable back stay bar for the lower part of the reed.

It will be understood that the details of construction of my improvements may be varied if desired.

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

1. A lay beam for a loom, comprising a wood beam, a rigid angle-shaped metal bar on the top and front of said beam, and a rigid T-shaped metal bar on the bottom and rear of said beam, and means for securing said bars to said wood beam.

2. A lay beam for a loom, comprising a rigid angleshaped metal bar forming the top and front of said beam, and a T-shaped metal bar forming the bottom and rear of said beam, and also forming a shelf or suport at the rear o f said beam, and means for olding said bars in position.

3. In a lay beam of a loom, the combination with a wood beam, of two independent rigid metal bars, one of angle shape forming the top and front, and the other of T shape forming the bottom and rear of the lay forming the bottom and rear of the lay beam,

and the T shaped bar forming also a shelf and support for a longitudinally extending bar at the rear of the lay beam and means for holding said metal bars in position and securing them together, and a longitudinally extending bar at the rear of the lay beam forming the back stay for the lower part of the reed, and means for supporting and detachablyseeuring said back stay bar.

5. In a lay beam of a loom, the combination with a wood beam, of two independent rigid metal bars, one of angle shape, and the other of T-shape, the angle-shaped bar forming the top and front of the lay, and the T- shaped bar extending on the bottom and rear of said wood beam, and forming a shelf and support for a wood bar at the rear of the lay, and said bar, and a metal bar at the rear of the lay over said wood bar, and forming the back stay of the lower part of the reed, and means for detachably securing said back stay bar.

6. In a lay beam of a loom, the combination with a wood beam, of two independent rigid metal bars, one of angle-shape on the top and front of said wood beam, and the other of T-shape on the bottom and rear of said wood beam, and said T-shaped bar forming also a support for a bar at the rear of the lay beam, and means for securing said metal bars in position.

7. In a lay beam of a loom, the combination with a wood beam, of two independent rigid metal bars, one of angle-,shape on the top and front 'of said wood beam, and the other of T-shape on the bottom and rear of said wood beam, and the T-shaped bar forming also a support for a bar at the rear of the lay beam, and said bar, and means for securing said metal bars in position, and a longitudinally extending bar at the rear of said wood beam, forming the back stay for the lower part of the reed, and means for supporting and detaohably securing said back stay bar.
