SPINNING FRAIVIE.

SPECIFICATION forming part of Letters Patent No. 621,255, dated March 14, 1899.

Application filed Gotober 19, 1898- Serial No. 693N75- (No modeh) To all whom it may concern.-

Be it known that I, GEORGE W. KNIGHT, of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Spinning-Frames, of which the fol-' lowing description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of simple and effective looking or retaining means for holding in place the capbars of a spinning-frame, whereby they may be readily and quickly removed or replaced without the use of tools.

Figure l is a top or plan view of a portion of a spinning-frame, partly broken out and showing only one section of top rolls with my inventionapplied to the apparatus. Fig. 2 is an enlarged transverse sectional view of the frame on the line m 00, Fig. 1, looking toward the left; and Fig. 3 is an enlarged rear elevation showing my invention in position to permit removal of a cap-bar.

The lower rolls R, supported in frames A, carried by the usual stands A one of which is shown in Fig. 2, and the upper rolls R, arranged in sections and having their journals mounted in arms 0 of the cap-bars C, may be and are of usual or welleknown construction in this class of apparatus.

The cap-bars O are herein shown as removable and cut away at adjacent ends, as at 0, (best shown in Fig. 3,) to receive the bearings a, formed at the rear upper ends of the frames A, the ends of the bars when in operative position abutting against said bearings.

Axial sockets or recesses 0 in the ends of the cap-bars are in alinement when said bars are in position and are entered by asliding retaining bolt or keeper d, mounted in the bearing a, the latter having a transverse slot a, to be traversed by a stud-like handle 01 of the bolt or keeper.

The keeper is longer than the bearing a and when midway in the latter projects beyond its sides into the sockets 0 of two adjacent cap-bars, as shown in Fig. 1, retaining them in place.

A locking-slot a intersects the slot at, and in order to retain the keeper, and consequently the cap-bars, in operative position the actuating-handle d of the keeper is thrown down into this locking-slot, as in dotted lines, Figs. 2 and 3. I

By unlocking the keeper and sliding it in one or the other direction one of the cap-bars O with which it cooperates will be released, and when both keepers of any given cap-bar are withdrawn from engagement therewith the bar can be at once lifted from the frame.

The keepers serve as fulcra for the cap-bars when in operative position and provide firm supports therefor.

By the construction herein set forth the use of tools to detach or apply'a cap-bar is entirely obviated.

Having fully described myinvention, what I claim, and desire to secure by Letters Pat'- ent, is

1. In a spinning-frame, a plurality of re movable cap-bars, a fixed bearing interposed between the ends of two adjacent cap-bars, a sliding keeper carried by and longer than the width of the bearing, to cooperate when in mid-position with both cap-bars and provide retaining-fulcra therefor, longitudinal movement of the keeper withdrawing it from and releasing one or other of the cap-bars, and locking means to retain the keeper in midposition.

2. In a spinning-frame, a plurality of removable cap-bars provided with longitudinal sockets at their ends, a fixed bearing interposed between the ends of two adjacent capbars, a sliding keeper carried by the bearing and adapted to cooperate with the cap-bars, or be withdrawn from one or the other to release them, and a locking device to hold the keeper in cooperative engagement with both bars.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE W. KNIGHT.
