Description
i@ Eg JAMES A. WIX, 0F GOLDVILLE, SOUTH CAROLINA.
v Loon :ROCK-SHAFT BEARING.
Application filed May 25,
To all whom t may concern.'
Be it known that I, JAMES A. 1Winx, a citizen of the United States, residing at Goldville, in the county of Laurens and State of South Carolina, have invented certain new and useful Improvements in a Loom Rock- Shaft Bearing; 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.
This invention relates to looms and more particularly to the bearing of the rock shaft whereby the same may be maintained in level position and provision had for taking up wear.
rlhe bearing is designed chiefly for looms having short rock shafts and prevents unequal wea-r and the tendency to bind as the weight of the lay is carried between two bearings. e
Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.
`While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.
Referring to the accompanying drawings forming a part of the specification,
Figure l is a front view of a rock shaft bearing embodying the invention and designed particularly for the Crompton and Knowles forty inch loom.
Figure 2 is a top plan view of the bearing, and
Figure 3 is an end view thereof.
The bearings will be provided in right and left, one for each side of the loom. It will thus be understood that one bearing is the counterpart of the other except for the relative relation of the partsmade necessary 'to adapt a pair of bearings for opposite sides of the loom. Each of the bearings comprises two boxes l and 2 which are spaced apart and disposed in longitudinal alignment. An arm or standard 3 projects from off the bearings as l and rovides means whereby the bearing as a w ole is adapted Specification of Letters Patent.

to be attached to the frame of the loom. For this purpose the arm and standard 3 is provided with longitudinal slots et and of standing projections as indicated more clearly in Figure 3 whereby to engage corresponding depressions of the frame thereby to insure a substantially and rigid connection, A substantially U-shaped frame 5 connects the inner or opposing ends of the boxes l and 2. The several parts l, 2, 3 and 5 are preferably of integral formation and constitute elements of a single casting. The openings 6 in the boxes l and 2 provided for reception of the rock shaft 7 are elongated vertically. A follow block 8 is located in the lower portion of the opening 6 of each of the boxes l and 2 and is vertically adjustable by means of set screws 9 threaded in openings formed in the bottom or lower portion of each of the boxes. The rock shaft 7 rests upon the follow block 8 and obtains a snug fit between such hollow block and the upper walls of the openings 6. These boxes l and 2 are maintained in alignment by reason of the substantial connection 5. The rock shaft 7 as is well known carries the weight of the lay and the sword, the latter being secured to the rock shaft in any preferred way. As aA result the lower portion of the bearing is subjected to wear which in the present instance will 'be adjusted to compensate for such wear by means of the set screws 9. It will thus be understood that the rock shaft may be maintained in level position and the working part associated therewith preserved in the predetermined position whereby the eficiency of the loom is maintained and replacement of worn parts obviated. The sword (not shown) is adapted to be attached to the rock shaft 7 intermediate the boxes l and 2 thereby equalizing the weight on the bearing as will readily be appreciated. The bottom portion of each of the boxes is made heavy to provide a substantial and durable bearing for the set screws 9, the latter being held in the adj usted position by means of binding nuts 10 mounted thereon.
Having thus described the invention, what I claim is A loom rock shaft bearing comprising a pair of boxes having elongated and vertically disposed openings, blocks adjustable in said openings and engaging and forcing a rock shaft against the upper Walls of the openings7 a horizontally disposed U-shaped frame connecting the boxes, and a vertical arm formed on one of the boxes and adapted to he secured to the frame of a loom7 said arm having projections and slots. and.Y the latter adapted to receive projections on the loomv
