IMPROVEMENT IN SPINNING-MACHINES.

Specification forming part of Letters Patent N0. 44.283, dated September 20, 1864.

.To all whom, it may concern.-

Be it known that I, E. U. CLEVELAND, of \Vorcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Spinning lliachinery and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figures l and 2 represent an elevation of a section of. a spinning-jack which contains my improvements, the line of section being the red line x, Fig. 3, the carriage being the part designated by the Fig. 2. Fig. 3 represents a sectional elevation of the back part of the jack as seen from the front of the machine, containing the posts and the arch which holds the clock, the line of section being the red line y in Fig. 2. Figs. et and 5 are views of detailed parts. Fig. 7 is an elevation of a part of the carriage, showing one of the tin drums which .give motion to the spindles, and the shaft and hand-wheel by which the tin drums are set in motion; and Fig. 6 is a sectional view of one of the bearings of said shaft and hand-wheel. Fig. 8 is a perspective view of that part ofthe jack which contains the clock and the mechanism by which it is operated, and also ot' a section ot` the carriage.

Similar letters of reference indicate corresponding parts.

My invention consists in certain improvements in the construction ofjaeks, whereby I am enabled to place the clock for indicating the amount ot' work done and its mechanism within the frame of the jack, and also in the construction of the mechanism for causing the clock to indicate the work of the jack, and in the manner of operating said mechanism, and also in the manner ofconstructin g and adjusting the bearings of the shaft which drives the shaft of the tin cylinders.

Figs. l and 2 represent the framing of'an ordnary jack, and A A are the center' and righthand rails on which the carriage BG runs in and out, the other rail being excluded by the section.

C2 represents the upright posts and arch which in my improvements are substituted for the ordinary posts and their girt, and for the additional 'trame and case, sometimes called the clock-post,77 intended to hold the clock and its actuating mechanism. The arch and posts C2 are in myimprovements made hollow, so as to contain the mechanism they are to sustain. The right-hand post()2 is left open on its outer or right-hand side, but the other post is to be closed by a removable cover, C3. The inner face of the arch is also covered by a door, which is represented in place in Fig. l and removed in Figs. 3 and S. The cavity of the arch communicates with that of the post. as shown, so that they are continuations of each other. The clock is placed beneath the crown ofthe arch, and an arbor passing through its center is armed with a toothed wheel, which takes into a worm on a horizontal shaft, K, which is xed in proper bearings beneath the dial of the clock. A ratchetwheel, K, is secured to the lefthand end ot the horizontal shaft K', and its return or backward rotationis prevented bythe springdetent I. The ratchet-wheel is rotated in one direction by means of a pawl, h, which is sc cured in two bearings, through which it movi s vertically upward, being held in its normal position by a pin or dog, .10, on its shank resting onthe lower bearing. A spring about its shank rests ou or is secured to the pin, and its upper end bears against the upper of the two bearings, the office of the 'sprin g being to return the pawl to its normal position. The pawl his in line over, but not in contact with, the top of a vertical lifter, C, whose shape is shown in Figs. 1,3, 4, 5, and S, and which extends below the line of the shaft A2, so that it may be conveniently operated by the devices I use for lifting it. Near its upper end it carries a horizontal arm, a3, which carries a loose toothed wheel, d,whosefaceis perforated by an annular row ot' holes near its circumference, which are to receive pins f, whose enlarged heads are clamped between the toothed wheel and a clamp or washer, g, which is secured upon the end of the arm I have shown two pins in holes about on opposite sides of the wheel, so that when the wheel L rotates its rotation will continue during onehalf a revolution before one of its pins comes against the plate e. The back plate of the post C2 is slotted to make room for the arm a and the plate e, the latter being of irregular form and the greater part of itbeing contained within the post. The vertical lifter O rests upon the back rail of the frame A when at rest. A curved toe, c', projects from the lifter C through the front of the post G2 at about the level of the carriage BG, by means of which the lifter is raised oft' the rail when the friction-roll or arm c ofthe carriage strikes against the. toe. An arm, D', projects from the lifter at its lower end, passing through a slot in the back of the post C2 and resting in one arm of a double crank, af, which is secured to an adjustable bracket, 1, secured to an arm extending from the post. The other arm of the crank takes hold of the belt-shipper ct'.-

A2 is the main shaft, with its driving and fast-and-loose pulleys supported upon brackets fast to the posts. The upper part of the lifter U is enlarged, as shown in Figs. 4, 5, and 8, so that it may be formed with a shoulder, c', which shall rest at certain times upon the central raised part of the plate c. Thisplate e is loose in the post C2, being fitted so that its ends shall slide freely through the sides of the post C2, and permit its highest part, c, which s at right angles with the arms e2, to slide beneath the shoulder of the lifter. A spring, j,'attached to the inside of the cover C, bears constan tl y against the face of the plate e, as shown in Fig. 5, forcing it against the lifter and under its shoulder c' and holding it there. Vhen the friction roll or arm c comes.

in contact with the toe c' on its under side, the lifter C rises easily until the compression of the coiled spring around the pawl h becomes so great as to partially check the momentum ot' the carriage in its .backward movement, thereby preventing a shock to the jack-carriage when brought against the stops or bunter-s7 previous to a return movement, or a draw, so called.

Upon the front of the back rail of the frame is an ad j ustable bracket, r', which carries a double crank, 02, whose outer arm,0', extends toward the carriage B6, so as to be struck by its arm or friction-roll o when running in. This crank is by this means caused to rock, thereby moving the slide F of the box E' te the right, by means of the pin n' of the slide resting in a slot in the. vertical arm of the crank o2. The box E' is supported between the posts G2, and carries brackets, which furnish bearings for a shaft, a, back of the frame. This shaft. is driven by a belt running from pulley AG over its pulley q. It has a bevelgear, p, secured on it in such a position as to be at certain times engaged with the bevelpinion p' on the cross-shaft 8, which latter reaches from the rail V of the frame over the box E, its bearin g at its outer end being fast to the slide F in an adjustable box, so that this end of the shaft will move with the slide without cramping the bearing. The shaft 8 carries a worm, o, at about the center of its length, and a bevel-gear, l0, on its inner end, the latter engaging with the bevel-gear 11 on the shaft l2. The shaft l2 extends the whole length of the j ack and drives the parallel shalt l5 by a train of gearing shown in Fin. 1. The

drawing-rolls 14 are supported upon these shafts and are rotated by them by frictional contact. ,The shaft 12 also drives the shaft which carries the roping spool-drums 4 by gearing on the outside ofthe framing; but as these parts are not changed by my improvements, I have not shown them in full. An upright arm, H, borne by a bracket secured to the box E', carries a toothed wheel, I, perforated and armed with two pins and a clamp or washer, J2, in all respects like those which are xed to the arm ai above mentioned. When the worm o on the shaft 8 engages with it, it will rotate until one of its pins strikes the spring-stop J', and thereby releases the slide F, and allows it to move back to its normal position to theleft,carrying with itthe shaft 8, and thus disengaging the worm o from the toothed wheel I, and the bevel-wheel p' from. the bevel-gearp. The slide F is locked in its position, when moved to the right by the crank o2, by a pin within the box E', which is secured to the arm J', and which is constantly pressed against a notched projection from the slide by a spring secured to the outer side of the box. A spiral spring fastened to the slide within the box draws it constantly to the left.

The operation of these parts (such of them as are contained within the box E' not being shown) is as follows: The pressure ofthe fric tion roll or arm o throws the slide to the right, when it is locked in that position by tl e pin on the inner end of the arm J', which is thus thrown outto an advanced position under the pin-wheel I. This movement of the slide causes the bevel-gears p' and p to engage, as well as the worm o and wheel I, and the toothed pin-wheel I I is thereby caused to revolve until one of its pins strikes aga-inst the arm J', thereby pushing it inward and unlocking it from the slide F, when the spiral spring (not shown) on the bottom of the slide draws it to the left, thereby disengaging the bevel-gears p' and p and the worm o and wheel I I. The rotation of the shaft 8 is for the purpose of giving the required rotation to the draw-rollers lying upon shafts l2 and l5, to enable them at the proper time to draw off a supply of roping from the roping-spools. The left end of the shaft n carries a worm, S, which engages the toothed pin-wheel d whenever it is carried to its highest position by the upward movement of the lifter C, the operation being as follows: Vhen the carriage has about completed its running-in motion, its arm c strikes the toe c' and carries up the lifter C to the position shown in Figs. 4 and 5, where it is locked by the sliding piece c, which is then thrown beneath its shoulder c' by the pressure of the spring j. This movement of the lifter also changes the belt by means of the crank a and shipper a'. The lifter carries the toothed wheel al up until it engages with the worm S, which sets it in motion. The 'upward movement of the lifter C drives the pawl h against the ratchet-wheel K and rotates it the distance of one tooth, thereby advancing the index or moving the dial according as one or the other is connected to the spur-wheel which enga-ges with the Worm on shaft K. The toothed wheel d rotates until one of its pins, striking against the edge of the loose plate c, overcomes the pressure of the spring j and slides the plate from beneath the shoulder of the lifter O, which then falls by gravity and the force of the spiral spring on pawl h to its lowest position.

The tin cylinders AO, which drive the spindles, reqpire frequent adjustment backward or forward to admit of new bands and to conipensate for expansion or contraction in the flexible bands. This could never be done in jacks as they are now usually constructed without making the gears which connected their shaft to the. shaft of the hand-wheel to bind. I have invented a method of obviating this difliculty, as follows: H is a journalbox, which is fastened to each end of the frame of the carriage at W,so that it can be moved about it as a fulcrum. A slot, W', is cut across the box to allow the passage of a bindingscrew, whereby the box is fixed in any position desired. A bracket, J, is fixed to the frame alongside of the journal-box, through which an adjusting screw, K2, works to bear against the inner edge of the box. The gearwhecls E of the drum or Vtin-cylinder shaft meshes with the gear E of the hand-wheel shaft B2, as seen in Fig. 7, and both these shafts are supported in boxes springing from a curved adjustable bracket, B5. (Seen in Fig. 7.) These shafts are so secured within their boxes that they have no endwise motion therein, and it follows that when the bracket which supports the boxes is adjusted in any direction the shafts will be maintained in their relative positions so that their gears cannot bind. W hen the shaft B', which carries the tin cylindeis, is moved toward or away from the spindle-rail, the shaft B2 will have an endwise movement to the same extent. To allow of this endwise movement of the shaft B2, I have constructed the upper bearing for said shaft in the following manner: A ball, 1, slipped upon the shaft and free to move thereon, rests in a socket in a bracket or bearing, B3, whose upper half is removable, and when in position covers the shaft for the greater portion of its length.

Instead of the ball-and-socket joint I propose to substitute another form of bearing for this end of the hand-Wheel shaft, to accomplish the same result-to wit, a close or quill box with trnnnions, as shown in Fig. 9, the quill resting upon the trunnions and yielding freely to any change of position required of the hand-wheel shaft. The quill is to beheld in place by a cap, the saine as in the case of the ball-joint. NVe now construct this part of our invention in the way last described.

I claim as new and desire to secure by Letters Patent- 1. Inclosing the lifter C and the clock and their appurtenances within the arch and one of the posts of the frame substantiallyY as described.

2. rlhe locking-slide c, constructed and operated substantially as shown, for locking the lifter G.

3. The lifter C, for operating the clock, constructed and operated substantially as shown.

4t. Adjusting the relative positions of the hand-wheel shaft and the tin-cylinder shaft in the manner substantially as described.

5. rlhe combination of the bearing of the hand-wheel shaft with the means employed for adjusting the inner end of the shaft, substantially as described.
