Specification forming part of Letters Patent No. 42.330, dated April l2, 1864.

To all whom if may concern,.- f i Be it known that I, HIRAM H. Gorla, a resident of Lonsdalevillage, of the town of Gumberland,in the county of Providence and State otlthode Island, have made a new and useful Invention having reference to Mules for Spinning; and I do hereby declare the same to be fully described in the following` specilication and represented in the accompanying drawings, of which- Figure l is a top view, Fig. 2 a longitudin alsection, and Fig. 3 an end elevation, of the said'invention, its purpose being to eii'ect the requisite changes in theoperationot several pltrts or" the mule at the termination of each movement of the mule-carriage on itslailway.

I have not represented the whole of a mule in the accompanying drawings, but only those parts thereof to which my invention is specially applicable.

In the drawings, A denotes that portion ot` the mule-frame which serves to support my invention, there being a cam shaft, B, sus tained in boxes t a, upheld by this portion A, and arranged therein, as shown in the drawings. This shaft is the usual camshaft of the self-acting mule, and carries certain cams, (l D, suitably formed to eft'ectfthe movements of the levers E, F, Gr, H, and I. The lever E is for the purpose ot' moving what is termed the ,roller-clutch77 ot the mule. The lever F is fur the purpose'ot' 4shifting the driving-belt of the mule. The lever Gis for operating the scroll clutch, by which the mechanism for running the carriage in is put in operation. The lever His for operating the back-oft' friction,7l` or the mechanism by whichA the rotary motions of the spindles are reversed. The lever I serves to putin operation the mechanism by which the carriage is run out. With these levers, their cams, and shafts, I have c'mibined my invention, which may be described as follows: On the cam-shaft B is a gear, L, which engages with a curved rack, M, projected upward from a lever, N, which is arranged within the frame A, in manner as shown in Figs. l and 2, the said lever being supported on a horizontal fulerum or pin, c, on which it can play in a vertical plane. To the rear extremity of the leverN a weight, O, is suspended. The said lever has also two arms, P Q, projecting down from it, and arranged as seen in Fig. 2, one ot' the said armsviz., Q-being provided with a friction-roller, (l, arranged on a pin projecting from the inner side of the arm. There is another such roller, e, suitably appliedpto a projectiomf, extending from the rear arm of the .lever N. This roller e operates with a weighted rocker-lever, R, shaped and arranged as shown in Figs.l and 2, and playing or being supported on a pin or t'ulerum, g. This lever lt has two projections, It t', which are formed and extended fromit,as shown in Fig. 2; and, furthermore, the lower arm ot' the lever is a weight, made so heavy as to ovcrbalance the rest of thel,h lever and its projections 7L t'. A

S is the center head of the mule carriage or carriages. This center head and its carriages are supported by wheels running on railways,

in the usual manner. Furthermore, an arm T, projects from the center head, as shown in Fig. 2, and serves to aeton the roller d, and serves to trip or pull down the front arm of the lever N while the center head may be runnin in.

T', Fig. l, "s a spring-catch, which is fastened to the frame A, and operates with a stud, k, extending from the rear side of the lever F. For throwing this spring-catch out of action with the said stud 7s, thereis an arm or finger,V U, which projects from the cam shaft B and over the catch, as shown in Fig. l. A long;l rod or latch, V, is jointed to the lever G, extends under the shaft B, and has a. catch on` its outer end to catch on a catch-plate, l, arranged as shown in Fig. 2. There is a spring, m, a, or o, to each of the levers F G I, suchspring being for the purpose of moving theA said lever in a direction contrary to that which it receives from its cam.

W (see Figs. 2 and 3) is the shaft which serves to support and operate the mechanism or portions thereof not only by which the carriage is reversed, but by which the back-oft' ot the spindles is effected. The lever H has its fulcrum at its foot, in order that the lever may swing both toward and away from the frame A. At the upper end of the said lever H is a plate, X, through which there is a slot, m', arranged at an obtuse angle with the lever, and serving to support a pin, u, which slides freely up and down in the slot and extends into the groove ot the cam D, there being a l friction-roller on that part of the pin which projects into the groove. The object ot' the slotted plate X and its movable stud is to prevent the lever H from being moved by the cam D when the carriage arrives at the beam or completes itsinward movement. The camshaft, instead of' making an entire revolution, as it does in ordinary mules, has, by my invention, a reciprocating rotary motion, and therefore there must be some means of preventing the lever H from being moved by the cam D, When the carriage completes its inward movement. The inclined slot enables the stud to rise in the groove of the cam, and counter-acts the movementof it which thecam would make. During the outward movement ot' the carriage a pin, x, (or its equivalent,) projecting from the center head will be car'- ried into contact with the part t' of the rockerlever-R, and will so move the rocker-lever vfrom the roller e as to enable the weight O to depress the longer arm of' the lever N, and thereby cause the curved rack, by its action on the pinion or gear L, to put the cam-shaft B in rotation in one direction. During the return movement of the carriage the arm or dagger T will be so moved against the upper part of the periphery ot' the roller d as to depress' the shorter arm of the lever N, and of course elevate the longer arm of such lever, which will be caught and held up by the rockerlever, which will be moved back by the gravitating power of its weighted lower arm. This latter movement of the lever N will cause the curvedrack, by its action on the gear, to rotate the cam-shaft in an opposite direction. The upward movement of the shorter arm ot' the lever N causes the elevation and unlatching of the latch V from its catch-plate, on which it will have been previously -latched by the lever G. The unlatehing of the latch V enables the spring ot' the lever G to move the said lever. While the carriage may be running in, the nger U will be turned down, so as.v to unlatch the catch T from the stud k, thereby setting the lever F free. When the carriage ofthe mule has been run out, the carriage friction apparatus and the rollerclutch are thrown out of action, and the driving beltis moved from the driving-out77 to the driving-in7 pulley. The back-ofi friction apparatus is also put in operation, and causes the spindles to reverse their movements. The carriageis novi7 prepared to be runin, which will be effected by throwing out of action the backoft friction apparatus and by throwing the scroll-clutch into action. On the arrival of the carriage at the beam the scroll-clutch is to be thrown out of action, the carriage friction apparatus and the roller-clutch being again thrown into action, and the driving-belt being shipped to the driving out pulley. These sanne operations are continued for each stretch of the mule-carriage. Heretot'ore these effects have been produced by a long lever, a spiral spring, a contact-pulley, a leather frictionpulley, a boot,7 a lever- `ipring, an elbow, a rubber spring, a stud, and a pitman or dagger,77 they causing the cam-shaft B to make an entire revolution during each stretch ot' the carriage-that is, while the carriage may be running out and in.. f

In carrying out my invention I have dispensed with all of these mechanical contrivances, except the long lever and the dagger or arm, they being used as shown at N and T in Fig. 2, and I employ the gear L, rack M, the weight O, the spring-catch T' and its stud k, the latch V, the ringer U, and the slotted `inclined plate X and its movable stud or pin'u,v all of which are arranged and applied as here#` inbefore specified, the cam-shaft B having im-` parted-to it, as hereinbefore stated, reciprocating instead of continuous rotary motions.

The advantages of my invention, 'compara-- tively speakin g, are, the attainment of less err--L pense of mechanism, certainty of action, andr little or no noise, better winding of the cops, less liability of breakage of the mule-head, less repairs, and a greater production of yarn under like velocities of the spindle.

I claim as my invention- The combination of the lever N, dagger or` arm T, gear L, rack M, Weight O, spring'- catch T', with itsstud k, the ylatch V, the linger U, the slotted inclined plate X, and its movable stud or pin u, the Whole being applied to the cam-shaft and the levers as hereinbefore described, and so as to operate subf stantially as specified.
