LEASE-ROD.

SPECIFICATION forming part of Letters Patent NO. 624,658, dated May 9, 1899. Application filed January 26, 1899. Serial No. 703,413. (No model.)

T0 at whom it may concern:

Be it known that I, HAROLD KELLY, a citizen of the United States, residing at Biddeford, in the county of York and State of Maine, have invented certain new and useful Improvements in Lease-Rods; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in lease-rods, and the same is illustrated in the accompanying drawings, in which Figure 1 is a perspective View of so much of a loom as is necessary to show the application of my improved rods thereto. Figs. 2 and 4.- are an elevation and cross-section, respectively, of a lease-rod. Figs. 3 and 5 are an elevation and cross-section, respectively, of a difierent form or shape of lease-rod. Fig. 6 is a sectional view of the adjustable rod-holder, and Fig. 7 is an end View of the holder.

Same letters of reference refer to like parts.

The warp-threads when they leave the beam are frequently stuck together by reason of the sizing or interlocking of fibers or knots in the thread, and when separated by the usual lease-rod threads are in consequence often broken, causing much delay and imperfection in the Woven goods.

The object of my invention is to obviate these difficulties.

In said drawings, A represents the frame of a loom; B, the beam; 0, the whip-roll, and D the warp.

My invention relates particularly to that one of the lease-rods nearest the beam.

It consists in a rotatable rod.

It further consists in means for imparting a rotary motion to said rod.

It further consists in means adapted to render the rod quickly and easily mounted in and dismounted from its sup orts.

To these ends I secure to either side of the -frame upright standards E, with suitable horizontal bearings F at the top. Mounted in said horizontal bearings are shafts G, having on the ends thereof socketed'holders H, adapted to receive and support the ends of the rod. Said rod may be rotated in any convenient manneras, for example, by a belt I, passing over a pulley J on shaft G and a pulley K on shaft L.

It is important that the rod may be quickly and easily inserted and removed from the warp. I therefore make one of the support ing-shafts capable of longitudinal movement sufficient to releasethe end of the rod from the socket in the holder. This construction I have illustrated in Figs. land '7. I The shaft upper and lower threads on the-rod passes through a longer or shorter dimension of the rod. The rod may therefore be of any shape in cross-section except circular. The shapes shown in Figs. 3 and 4 are examples in which the longer and shorter dimensions are marked. It will be evident that the cross-sectional shape of the rod may be indefinitely varied without departing from the spirit of my invention. The supports which carry the rotatable holders canbe adjusted vertically by moving the standards up or down in tubular brackets S, secured to the sides of the frame, and may be held in any desired position by set-screws T, thus increasing or diminishing the tension on the warp. It will also be evident that the manner of supporting the rod and the means for imparting a rotary motion to the rod may be varied at will Without departing from the spirit of my invention, the leading feature of which is the rotation of the rod next the beam, said rod having unequal diameters.

The operation of my improved lease-rod is as follows: The warp-threads constantly un- I the whip-roll. side, and likewise the tension,

thereby more gradually separating the threads and rendering them less liable to be broken.

Having thus described my invention and its use, I claim .1, In a loom, a lease-rod, means for supporting said rod independently of the warp threads and means for imparting a rotary motion to said rod.

2. In a loom, rotatable holders, a lease-rod mounted therein, one holder being held yieldingly against longitudinal movement and means for rotating said rod.

3. In a loom, rotatable holders, a lease-rod supported therein, means for rotating'said holders and rod, said rod having diameters of varying length.
