LAY FOR LOOMS.

Application filed December 12, 1927. Serial No. 239,327.

This invention relates to improvements in loom lays and it is the general object of 1 the invention to provide an improved stron but light backstay more particularly for sil 5 or towel looms.

It is customary in silk looms to mount the reed in a pivoted framewhich may swing relatively to the lay so that should a shuttle be caught in a shed the reed may yield rather than force the shuttle forwardly to break out a number of warp threads. A frame should be stiff enough to hold the reed straight but as silk looms are run at a rather high" rate of speed it is desirable also that the backstay should be as light as possible.

The lower end of the reed is ordinarily received by a, groove or slot cut in the backstay, the reed cap being moved downwardly to hold the reed tightly in position. It is a further object of my present invention to provide an improved stiff but light backstay formed in part of an angle iron one of the sides of which helps to define the slot which receives the reed. 4

7 With these and other objects in view which will appear as the description proceeds, my invention resides in the combination and an rangement of parts hereinafter described. and set forth in the claims.

In the accompanying drawings wherein one form of my invention is shown,

Fig. 1 shows one end of'the lay together with the reed and the means for mounting the same, certain parts being in section,

Fig. 2 is a vertical section on line 2-2 of Fig. 1, and

Fig. 3 is a of Fig. 1.

Referring to the drawings the lay 10 is mounted on swords one of which is indicated at 11 and has secured thereto a lay end 12 having an upwardly extending projection 13. The projection has a lug 14 in which is secured a pin 15 to project into a corresponding lug 16 formed on bracket 17. The bracket supports the hand rail 18 by means of a bolt 19 extending through vertical and horizontal slots 20 and 21, respectively, formed in the hand rail and bracket, respectively. The hand rail is provided with a slot 22 which receives the upper edge 23 with the reed B. As shown more particularly in Figs. 1 and 3the bracket 17 has ahorizontally extending wing 24 which extends horizontal section on line 33 behind and is receivedby a notch 25 in the wooden part 26 of the backstay. Bolts 27 extend through the wing 24 and wooden part 26 to hold these parts together. As shown particularly in Fig. 2 the wooden portion 26 is provided with a longitudinal groove 28 on the upper right hand edge. This part of the construction isusual and except'for the formation of thegroove 28 forms no part of my present invention.

As heretofore constructed the lower edge 29 of the reed has'been confined in a slot formed entirely by the wooden part 26 of the backstay, but in certain instances this has been found to be of insutlicient strength and in carrying my invention into efiect I provide a strengthened construction employing an angle iron 40 substantially of the form shown in section in Fig. 2. The angle iron has a horizontal portion 41 which extends under the wooden portion 26 of the backstay and has also a vertical portion 42 through which the bolts 27 extend as shown in the drawings. The upper portion of the vertical section 42 projects above the bottom 43 of thenotch 28 and substantially parallel to the vertical wall 44 of said notch, defining with the latter a slot which receives the lower edge 29 of the reed. By this construction the bolts'27 which heretofore have served the purpose merely of holding the wooden part of the backstay to the wing 24 now serves the additional function of holding one side of the angle iron in fixed position to define a slot for the reed. I find that a backstay made according to the form set forth herein is very strong and is not subject to twisting, the angle section 40 serv ing not only to brace the backstay but also to keep the reed straight, a very important consideration in the weaving of anyof the finer fabrics. The description given has been in connection with one side of the lay, but it is to be understood that both ends of the lay will be made in substantially the same manner and that the angle iron 40 will. extend across the 100111. Bolts 45 may pass through the wood'26 and the vertical wall 42 to secure these parts together.

From the foregoing it will be seen that I have provided a backstay for a loom lay lllh the reed is located. The angle iron not only stifiens'the backstay but also assists in keeping the reed straight.

Having thus described my invention it Will be seen that changes and modifications may be made therein bythose skilled in the art Without departing from the spirit and scope of the invention and I do not Wish to be limited to the details herein disclosed,-

but What I claim is:

1,111 a lay for a loom having a reed, a

backstay movablerelatively to the lay and having a groovetherein, an angle ir'on'se cured to the baokstay and having a verticalportion along the front edge of the back stay, the vertical portion of said angleiron cooperatingwith the groove in thebacki stay to define a slot ivhich'r'eceives the lower "end of the'reed.

2; In a loom lay havingareed', abra'cket pivotally connected to the lay, a backstay, an angle iron secured to the baokst-ay and extending parallel thereto, and means extending through the bracket, backstay and defining With the notch a'slot, and a reed the lower portion of which'is received in said slot, a portion of said reedhavi'ng direct engagement with the angle iron.

I In test mony whereof I have hereunto EPPA H. RYON.
