SPECIFICATION forming part of Letters Patent No. 453,717, dated June 9, 1891.

Application filed November 7, 1890. Serial No. 370,613. (No model.)

To all whom, it may concern:

130 it known that I, GEORGE F. HUTCHINS, a citizen of the United States, residing at Worcoster, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Lay-Motions for Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the draw to ings making a part of this specification, will enable others skilled inthe art to which my invention belongs to make and use the same. My invention relates to looms, and more particularly to the lay-motion of a loom.

The object of my invention is to make a loom in which the lay shall have a substantially horizontal motioninstead of a circular motion ordinarily given to the lay of-a loom. My invention consists in certain novel fea- 2o tures of construction and operation of the lay 3o beam, all as ordinarily constructed.

of a loom, as will be hereinafter fully described.

Referring to the drawings, Figure 1 is a sectional side elevation of portions of a loom with my improvements applied thereto, and Fig. 2 is a partial front elevation looking in the direction of arrow a, Fig. 1.

In the accompanying drawings, 1 is the loom side, 2 theorank-shaft, and 3 the breast- On the stud 4-011 the loom side is supported a wheel or sheave 5, which turns loosely thereon. Onv

said sheave rests the shoe 6, secured to the under side of the lay '7. From the pin 8, in the rear part of the shoe 6, extends the connecting-rod 9 to the crank 10 on the shaft 2. An arm 11 is rigidly secured to a stand 12 on the rear side of. the lay 7. The opposite end of the arm ll is pivoted to the swinging arm 4 13, which is pivoted at its lower end on a stir 14, secured to the loom side.

The purpose of the arm 11, connected with the swinging arm 13 and rigidly attached to tli'e lay 7, is to steady thev lay (which simply rests on the sheave 5) and retain it in its upright position as the lay carrying the reed (not shown) heats up the filling. The length of the arm 11 (rigidly attached at one end to the lay) is such that the tilting motion given to the lay by the arm 11 and swinging arm be understood that there is a series of sheaves 6 'J 5, on which the lay 7 is supported by the shoes 6. The lay-7 is moved back and forth by the cranli 10 through the connecting-rod 9, and is retained in its uprightposition by the arm d1,\connected with the swinging arm 0,

13. When the lay 7 is in its extreme forward position, (see dotted lines, Fig. 1,) the....arm U of the shoe 6 is under the roll 16, and the shoe 6, secured to the under side of the lay, is

held firmly between the roll 16 and the sheave 5, thus holding the lay firmly at the. forward extremity of its stroke.

It will be understood that the details of construction of my improvements may 'be varied somewhat from what is shown, it de sired.

Having thus described my invention, what I claim as new, and desireto secure byLetters Patent, is-
