Application filed March 5, i887.

' description, reference being hadto the accompanying drawings, forming part of this speciiication. i

This invention relates to what is ordinarily I known as a self-acting spinning-mule.

I haveillustrated 'my'inventio'n in conj unction with sufticient portionsof the well-known Mason mule to readily enable any one skilled in this class of spinning machinery to-fully understand the cooperation of my improvements and the objects thereof. v

' The operations of the spinning-mule comprise three sets of motions, as followsi first, running out the catriagaturning the drawrollers, and rotating thesspindles for spinning the yarn; second, backing OH or unwinding the yarn from the spindle-heads to the cops and depressing the front fuller; third, running in the carriageand windingon the previously drawnaud twisted yarn. The dofting of the cops from the spindles isusually performed while the carriage is at the outward limit of its travel, or after the carriage has been run in a little distance. v This time is selected be-.

cause the front faller has then depressed the yarn toward-the base of thecop, so that after dotting the broken end of yarn can be secured to the spindle at a point where the base of the next-formed cop is to begin; In doffing it'is customary, after the machine has stopped, to

manipulate the machine by. hand in order to.

turn the spindles forward and backward'to wind on a little by hand and to gain sufficient slack to tie the yarn ends to the spindles, and moving Lethe machine by hand in order" to slightlyoperate the spindles has become such" a necessity thatin doffing oneor two operators are required to pull upon the driving-belt to effect the desired result on the spindles. During the period of the operation of the wind-0n motion and the simultaneous running-in motion in the form of mule wherein a top sliding rack'having but two motions is used as a Serial No. 229,853. (No model.)

One object of 'myinvention is to prevent the wind-clutch from clutching and/to maintain the clutch (open during dofifing,,whereby the 'toturn the spindles, it will only berequired ate of "the spindles and the clutch-pinion, since the parts stand disconnected at that point;

clutch open, an adjustable stop-arm fixed on justable block for the spring to takeagainst. Injorder that my invention may be fully the best formof my invention so far devised I by me, which form may be variously modi;

chine-frame, back-oft" arm, and section-rod being broken off and the back-oil wheel being in broken lines. Fig. 2 represents a top plan view of the parts shown in Fig. 1. Fig. 3 represents an enlarged detached view of portions of the back-oil rod and the wind-clutch lever, together with my spring-acted wind-clutch dog and adjustable block for the spring. Fig. 4 represents a side elevation of a Mason mulehead having my improvement attached thereto.

In the said drawings like numbers of reference designate corresponding parts throughout.

Referring to the drawings, the number 8 designates the machine framing of the mulehead for supporting the various mechanisms situated therein. The sector rod 9 is connected to the sector 32, which is actuated by the connecting-rod 33 in the usual manner,and the sector-rod rocks the sector 32 and back-off rocker 10, which is pivoted to the frame, and to the lower end of which the back-off rod 11 is loosely attached, while the other end of the hack'olf rod is pivoted to the lower end of the back-off arm 12, (shown partly in full and broken lines,) and which is-loosel y mounted on the wind-shaft 13, journaled across the ma-. chine-frame. j

Upon the wind'shaft is keyed the backbfi' gear 14, (shown in broken lines,) and the windclutch 15 is also mounted .on the shaft 13, and consists of the wind-clutch pinion 17,which is not fixed to the shaft, and the part 16, which is secured by a longitudinal feather on the shaft, and which is adapted to slide on the shaft and to always turn therewith. When the wind-clutch is open, the pinion 17 runs idle or loose,and when the clutch is closed the pinion obviously runs fast with the windshaft. 1 1

The immediate connections, which lie intermediate of the back-off rod 11 for operating the wind-clutch to clutch and unclutch, consist in a wind-clutch spring-fork, 18, which is fixed to the stand 19, which is secured upon the ma chine-frame and supports the rock-shaft 20, to one end of which is keyed the clutch-arm 21 for bearing upon the back of the spring-fork 18, which tends normally to keep the windclntch open, as shown. To the base of the rockshaft is made fast the wind-clutch lever 22. WVhen the lever 22 is moved toward the left, the rock-shaft will be rocked and will cause the clutcharm to bear upon the clutch-fork, and thereby close the clutch, which, upon the releasing of the lever, will be opened by virtue of the spring tension of the spring-fork. In the old form of machine the moving of the wind-clutch lever to close the wind-clutch is effected by means of an adjustable wind-clutch dog mounted on the back-off rod 11, and which is made fast thereon when acting. The top sliding rack, 23, is shown in portion and lies constantly in mesh with the wind-pinion 17.

The above'described parts are old and their respective functions are well known, and the following description will be easily understood.

The drawings show the several parts of the machine in a position while the back-ofl' motion is being performed by virtue of the sectorrod 9'being moved inwardly indirectly by the connecting-rod 33, thereby rocking the backofi' rocker 10 and drawing outwardly the backoff rod 11, which serves to throw down the up per end of the back-ofl arm 12, provided with a pawl, (not shown,) which pawl takes into the teeth of the back-off gear 14 only during thisdownward motion of the back-off arm and acts to turn the back-off gear throughout the downward movement of said arm. The motion is transmitted from the back-off gear 14 to the spindles by means of an idle-gear, 34, meshing with a gear fixed upon the frictionclutch shaft 35, and as the, friction-clutch 36 carries the spindle band or rope and is closed during the back-off the spindles are backed oil" or reversed through these means. At the completion of the back-oif the wind-clutch dog 27, fixed on the back-off rod 11, is so adjusted as to push upon the wind-clutch lever 22, and thereby indirectly close the wind-clutch 15. At this time the lower rack is run inwardly, and as this moves the top rack in, the pinion 17 being now fast relative to the wind-shaft and the connected back-oil gear, this movement of the top rack obviously rotates the spindles through the intermediate apparatus before alluded to, and winds on the yarn which has been previously drawn and spun.

As beforestated, the doffing of the cops is usuallyperformed when the carriage has moved in slightly from the outward limit of traverse, and under this condition of the carriage the wind-clutch is necessarily closed and the entire apparatus between the spindles and the running-in pulley is all connected when the machine is stopped for dotting, so that to turn the spindles slightly by hand all of the aforesaid apparatus must be moved, and this I deem a great defect.

It is the chief object of myinvention to overcome this defect by holding the wind-clutch open during dofling, thereby disconnecting the apparatus at this point. This resultI accomplish by means of using a stop which may be moved in or out of engagement with the immediate connections for operating the windclutch, which, when the stop is interposed, is prevented from closing. I have here shown the stop as being used to affect directly the operation of the rook-shaft 20. The stop itself consists of amovable member, 24, pivoted to the machine-frame and adapted to be thrown into engagement with the adjustable stop-arm 25, which is mounted on the rock-shaft and turns therewith, and is provided with a set-- screw, 26, for holding the stop-arm in adjusted position. The stop 24 is provided at the pivoted end with the spaced lugs 30, which act in conjunction with the fixed pin 31 on the machine-frame to limit the throw of the stop in an evident manner. Just before the machine is stopped for doffingI throw the stop 24 over' into the dotted-line position of Fig. 1, so as to lie in the path of the stop-arm 25 when the 5' wind-clutchlever is moved by thebaek-off,

rod to close thewind-clutch and obviously stop the rock-shaft and the connected clutch arm from moving sufficiently to close the windclutch, therebyleavi'n g it unclutched andhold- :0 ing it so while dofling, so that when the spindles have to be turned by hand only the apparatus between thesame and the spindleband, and also the closed friction-"clutch, its shaft and gear, and the idle-gear and back-off gear and the windshafthave to' be moved,

thus avoiding the labor of moving all the heavier apparatus intermediate of the wind-shaft and'the running-inpulley before referred to.

The employment of the character of'stop-I 2c show for holding the wind-clutch open requires a yielding mechanism to be used at a place near by in order to prevent breaking or'rupturing the machinery immediately connected with thewind-clutch, This need I supply by the use of a yielding wind-clutch dog, 27, sliding on the back-off rod 11, in place of the heretofore rigid dog. This sliding dog is'free on therod, and is engaged by a spiral spring, 28, coiled about the rod and abutting against the adjustable block 29,..which is designed to be adjusted in order to regulate the time when the compression of the spring will be sufficient to push the wind-clutch lever to close the windclutch in the ordinary manner while the cops are-being built. It is evident that when the stop 24 is putin. play for dofiing the backoff rod will operate, as usual, to push the dog against the wind-clutch lever and close the clutch; but the, stop will hold the lever rig- 4o idly 'and the spring 28 will be compressed to compensate for the stoppage of the dog, and

thus prevent the lever or other adjacent parts from being broken. c

It is to be observed that my yielding wind- I clutch dog willperform the requisite function i of closing the wind-clutch while the machine is running and forming the cops, and is adjustable by virtue of its spring and block to regulate precisely the time for closing the wind-clutch for the wind-on. My invention permits of the yarn being easily wound upon the cops by hand to the required extent in dotting, and thisis an important advantage, since thereby the likely destruction of the cop- 5 5' nose is renderedless'liable than heretofore.

. I desire to be understood as not being con; fined to the exact construction I have here shown of my invention, since there are many ways in which astop can be arranged to co- 6c operate with the immediate connections for operating the wind-clutch for the purpose of preventing the closing of the wind-clutch, as

described.

Having thus'described my inv ention;I claim I as new and desire to secure by Letters Patent- 1. In a spinning-mule, the combination, as

hereinbefore set forth, with a wind-clutch and Q I a shaft therefor, and mechanism, substantially as, described, for clutching and unclut'ching the wind-clutch, of a movable stop acting to 7Q prevent the wind-clutch from clutching, where;
