COTTON-SPINNINGMULEL SPECIFICATION forming part of; Letters Patent No. 483,391, dated September :27. 1892. t Application filed May 2, 1892. Serial No. 431,508. (No model.)

To all whom it 12mg concern.-

Be it known that I, CHARLES A. DAM, of

Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Cotton-Spinning Mules, of which the following is aspeoitication.

My invention has relation to windingmechanisms for cotton-spinning mules in which a clutch-boxis employed in lieu of a click-wheel for setting the winding motion in operation. .It is the object of my improvement to provide means which can be relied upon with certainty to maintain a stationary position out of action of the sliding clutch part during the outward run of the carriage, the process of backingoilt, and the mowement of the coppingrail, and which the moment the follower is locked will act to force the sliding clutch part into contact with the ppposite clutch part, so that the winding mechanism may be set in motiontheinstant the follower becomeslocked and be kept in operation until winding is eiiected as close as may be to the beam and the follower is unlocked. It is also the object of my invention to simplify the means-for operating the clutch-box and render the same more readyof adjustmont and repair than heretofore.

To these ends my invention consists of the clutch-box comprising the fixed and the slid.- ing parts, means connecting the fixed part with band-cylinder, a bell-crank lever one arm of which is engaged with the sliding part to operate the same, the end of the other arm being provided with a swivel or pivoted latch adapted to be moved to a limited extent without efiecting a movement of said lever; and connections between the said swivel and follower-leg, all as will be more fully described and claimed hereinafter. 1

Reference is to be had to the annexed drawings, and to the letters marked thereon, forming a part of this specification, the same lettors designating the same parts or features, as the case may be, wherever they occur.

In the drawings, Figure 1 is a sectional side elevation of so much of a mule-carriage as it is necessary to show in order to illustrate my invention. Fig. 2 is a top plan view of the essential features thereof, shown in connection with co-operating parts, the sliding clutch part being represented as in engagement with In the drawings, a designates the sliding part, and b the fined part, of the clutch-box, arranged on the shaft 0, upon which thereis a gear d, which'meshes with the gear e, connected with the winding-drum f.

g designates the square, and it other parts, of the frame of the mule-carriage.

i designates the follower-leg, provided'on its lower end with the oifset-bloek j, which is adapted to'catch over the bowl or rollerk when the follower is depressed and the winding mo: tion is in operation and to be moved oiffromsaid bowl when the follower is raised and out of operation.

The parts thus tar described, as alsothe means for operating and controlling the operations of the follower-leg and its connections,

form no part of my present invention and need not be more particularly described herein.

Z is an arm or bell-crank lever pivoted upon the square and having the end of one arm provided with a pivoted traveler m, arranged to move in a groove n of the hub of the sliding clutch part a of the clutch-box. The end of the other arm of thelever Zis provided with a swivel or pivoted latch 0, so constructed and arranged as to have a limited movement upon its pivot independent of the arm with which it is connected, as will be clearly understood by an inspection of Figs. 2 and 3.

p is a rod provided at each end with an eye, one end being connected to the swivel or latch 0 and the other end to a pin q, to which one end of a bar 0" is pivoted, the other end of said bar being connected in a similar manner with the follower-leg. With this means it will be seen that if the parts are, as they will be, as shown in Fig. 3 during the outward run of the carriage they will so remain until the backing off and movement of the copping-rail occurs,

the sliding clutch part of the clutch-box being held positively out of engagement with the fi'xed part. During the backing-olf movement and movement of the capping-rail the swivel or latch 0 will be moved from the position in which it is shown in Fig. 3 to that in which it 1s represented in 2; but the arm as" lever ZWlll not he moved until the backing 05 is efiected and the follower is locked. The instant the latter occurs, however, the arm Z will be moved to the position represented in Fig. 2, the clutch will be thrown into engagement, and the wiiiding=1notien set in operation.

By my invention I enahie the mule to wind closer to the beam during the inward run of.

- without moving the lever would fall within the scope of my invention. Having thus described the nature of my" invention and explained a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its employment, I declare that what I claim is- I. The shaft 0 and the clutch-box thereon,

tsaeoi comprising the fixed and sliding clutch parts, in combination with the lever Z, one arnlof which is engaged with the sliding clutch part, the end of the other arm being provided. with a. swivel or latch adapted to have a. limited movement independent of the lever, the follower-leg, and means connecting the followerleg with the swivel or latch, as set forth.

. 2. The combination,with the shaft 0, of the clutch-box comprising the fixed and sliding parts, means connecting the fixed parts with the band-cylinder, a bell-crank lever,'one arm of which is engaged with the sliding part to operate the same, the end of the other arm being provided with a swivel adapted to be moved to a limited extent Without affecting the movement of the lever, and connections between-the said swivel and 'follower-leg, as set forth.

In testimony whereof I have signed my name to this-specification, in the presence of two subscribing witnesses, this 23d day of April, A. I). 1 892.
