WILLIAM EARL, JR., on NAsHUA,

PATENT OFFICE.

NEW HAMPSHIRE, ASSIGNEE OF THOMAS PYE.

IMPROVEMENT IN SPINNING-MACHINES.

Specilication forming part of Letters Patent No. 46,386, dated February 14, 1865; Reissue No. 2,351, dated September 4, 1866.

To all whom it may concern:

Be it known that THOMAS PYE, of the town of New Hartford, in the county of Oneida and State of New York, did, on the 14th day ot' February, A. D. 1865, obtain of and from the United States of America certain Letters Patent for and upon certain new anduseful im-i provements in spinning machinery of woolen-f manufactories, and bearing the title of Improvements in Spinnin g-ll/iachines,77 which Letters Patent have been duly assigned to VIL-` LIAM EARL, Jr., by which assignment the said WILLIAM EARL, Jr., has become, and is, the true and lawful owner and holder of the entire interest in said invention, improvements, and patents 5 and I, the said WILLIAM EARL, J r., assignee of said patent, do hereby declare that the following is a full, clear, and exact description of the said invention and improvements, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which said drawings make a part of this specification.

Like letters represent and refer to like or corresponding parts.

Figure 1 is a perspective view of a spinningjack and the stationary machinery with which it is usually connected, with the said invention and improvements attached. The jack is represented at that point in its operation where it is drawn out farthest from the stationary machinery, and when the twist of the thread is completed and the jack is ready to be run up for the purpose of windin g the thread upon the bobbins. Fig. 2 is a rear view of the said stationary machinery shown in Fig. l, and shows the manner of the operation of the said invention in changing the belt from the tight to the loose pulley, as hereinafter described. Fig. 3 is a view of the slide-bolt, with the spiral spring by which it is actuated, and moving in the bolt-stock 5 also, the shoe or latch operated by the drop-lever attached to the bottom of the jack and connected with the follower and guide-wire, as hereinafter described and set forth. Fig. 4 represents a metal frame attached to the carriage of the jack, at the end of which frame is a friction-roller in the act of operating the crooked lever connected with the belt-shifter by means of the angular lever, as hereinafter set forth. Fig. 5 represents the said angular lever connected at one end by a chain with the slide bolt and spring above mentioned; also the crooked lever, which is operated by said friction-rol ler, and the oblique lever connected with and moving the beltshifter, as hereinafter described.`

The nature of the said invention consists in moving the belt-shifter of a spinning-machine by the ordinary operation of the machine, at the moment when the jack is drawn out to the utmost extent and when the thread is completely twisted and the jack is about to be returned, in such a manner that the drivin g-belt is thrown partially on the tight pulley, thereby materially assisting the operator in running up the jack and making a tight bobbin.

lt also consists in moving the said beltshifter by the ordinary operation of the machine at the moment when the jack is nearly run up and at the proper point for piecing up the threads, and just before the thread is completely wound up, in such a manner that the driving-belt is thrown entirely off the tight pulley and upon the loose pulley, thereby preventing the abrasion of `the belt upon the tight pulley while the jack is stationary.

It also consists in the employment of the various mechanical devices herein described, arranged, combined, and operated substantially in the manner and for the purposes hereinafter described and set forth.

Having thus described the nature of the said invention and improvements, and torenable others skilled in the art to whichjthe same relates to Inake and use the said invention, I will here proceed to describe the construction and opera-tion thereof', which is as follows, to wit:

A, Figs. 1, et, and 5, is acrooked lever with an oblique surface, V, moving on its center u, and attached at its lower end to the angular lever D, Figs. l and 5.

B, Fig. 5, is an oblique lever moving on its center j, with its lower end resting against the end of the angular lever D, and connected at its upper end with the belt-shifter C, Figs. l, 2, and 5. j y D, Figs. l and 5, is an angular lever moving on its center a, and connected by the chain E with the sliding bolt F, Figs. l, 3, and 3', moving in the bolt-stock Gr, Figs. 3 and 3',

bin, in the manner and by the means substantially as herein described and set forth.

2. rIhe moving of the said belt-shifter C by the ordinary operation of the machine at the moment when the jack is nearly run up to the required or desired point or place for the piecin g-up of the thread, and just before it is fully Wound upon the bobbins, in such manner that the said belt is thrown Wholly o' from the tight pulley aforesaid, and upon the said loose pulley, in the manner and by the means substantially as herein described and set forth.

3. The employment of the crooked lever A, the oblique lever B, and the angular lever D, as arranged and combined, and then the Whole in combination with the aforesaid belt-shifter C, in the manner and for the purposes substantially as herein described and set forth.

4. The employment of the chain E, arranged and combined with the angular lever D and the slide-bolt F, in the manner and for the purposes substantially as herein described and set forth.

5. The combination of the slide-bolt F with the coil or spiral spring H, the bolt-stock G,

and the shoe b, and with the drop or sliding bard, each being arranged and combined in the manner andfor the purposes substantially as herein specified, described, and set forth.

6. The drop or sliding bar d, and the Wire or cord e, connected and combined with the' Faller W, and with the shoe b b', in the manner substantially as and for the purposes herein described and set forth.

7. The employment of the lever A, having an oblique arm, c, in combination with the lever u, and with the carriage of the jack aforesaid, by means of the arm or frame L, containing the friction-roller M, each being arranged and operated in the manner substantially as and for the purposes herein specified, described, and set forth.

In testimony whereof` I have, on this 2d day of November, A. D. 1865, hereunto set my hand.

WM. EARL, J R.
