DEVICE FOR REMOVING PRESSURE FROM ROLLS F SPINNING-FRAMES, &c.
SPECIFICATION forming part of Letters Patent No. 329,975, dated November 10, 1885.
Application filed December 22, 1884. Serial No. 150,942. (No model.)
To all whom it may concern.-
Be it known that I, EDW. W. THOMAS, of Lowell, county of Middlesex, State of Massachusetts, have invented an Improvement in Devices for Removing Pressure from Rolls of Spinning-Frames, &c., of which the following description, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.
This invention has for its object to lift the weights from the top rolls when desired. To do this I have provided the machine at each side with a rock-shaft having arms or fingers adapted to lift the weighted levers of the roller-stands, and I have connected with the said rock-shafts mechanism whereby they may be moved when desired, the said mechanism being under the control of a hand-lever.
Figure 1 is a side elevation of a spinningmachine embodying my invention, the upper part of the frame and the rollers being in section in the line 00 :0, Fig. 2. Fig. 2 is a top or plan view of asufficient portion of a spinningmachine of usual construction to illustrate my improvements. Fig. 3 is a top view of one of the arms or fingers detached, and Fig. 4 a section thereof in the line 00 m.
The frame-work a, roller-stand b, rolls 0 d, saddles e e, stirrup f, levers g, rod h, weight 1', stirrup-serew m, roller-beam n, and main shaftpare all old and asinspinning-machines now commonlyin use.
In accordance with my invention I have mounted on this common frame two rockshafts, A, and to the said shafts I have attached lifting arms or fingers B by means of set-screws 0, so that the same may be adjusted thereon in desired position. The arms B at their outer ends are provided with openings 2 for the passage of the rods 71, the crosspieces 3 at the ends of the arms extending under the levers 9, so as to act against and lift the said levers and their attached weights when the rock-shafts are turned by mechanism to be described, such lifting of the levers removing the customary pressure from the saddles of the top rolls. The rockshafts A A at their ends are provided, as shown, with arms D, connected therewith by set-screws 4. These arms D are joined loosely by pivot-pin 5 with the link E, connected by pin 6 with the arm 7 of a hub, F, mounted loosely on the usual end box supporting the shaftp, the lat ter serving merely as a fulcrum for the hub. A hand-lever, G, is connected with an arm, 8, of the hub F. Movement of the hand-lever G from its usual position, Fig. 1, in the direction of the arrow 10 depresses the ends of the arms D D and turns the rock-shafts to elevate the fingers B and lift the levers My invention is applicable not only to that class of spinning-machines known as ringspinning frames, but also to roving-frames, wherein top rollers are used which are held down by saddles, stirrups, and levers.
I claim- 1. The rock-shaft provided with fingers,and means, substantially as described,whereby the rock-shaft and link may be moved, combined with the roller-stands, rolls therein, saddles, links,and levers g, and means to support the same, with its attached weights, substantially as described.
2. The two sets of roller-stands, rolls therein, saddles, stirrups, weighted levers g, and two rock-shafts, A, provided with fingers B, combined with the arms D D, link E, and means whereby the latter may be moved to lift the levers g at each side of the frame, sub stantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
EDWARD WV. THOMAS.

GEORGE H. BENSON, JOHN R. ROARKE.
