IINITED STATES ROBERT WILDE, OF PHILADELPHIA, PENNSYLVANIA.'

IMPROVEMENT IN SPINNING-MULES.

Specification forming part of Letters Patent No. 56,133, dated July 3, 1866.

To all 'whom it may concern:

Be it known that I, ROBERT WILBE, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Spinning-Mules; and I do hereby 'declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure lis a side elevation, and Fig. 2 an end elevation, of a spinning-mule head, showing I my said improvement applied thereto, Fig. 3

being a plan View of the detached sliding rod or bar, in connection with the weight, pulley, and the levers which immediately operate to connect and disconnect the gear-wheels of the mule-head, like letters of reference indicating the same parts when in the different figures.

The object of my improvement is to produce and apply an apparatus which will be more efticient, as well as more simple and less costly in construction, and also more durable in use, for putting the roll and scroll wheels of a spinning-mule in and out of gear during the movements of the carriage; and the nature of my said invention consists in the employment of a weight, or its equivalent, in connection with a sliding rod and levers on the mule-head and operating studs or projections on the carriage, constructed and operating substantially as hereinafter described. v

In the drawings, A B is the frame of th mule-head; C, a representation of one of the positions of the carriage; D, the weight; E, the sliding rod; F, its operating-lever; Gr, its sustaining-lever; H, the gear-detaching lever, and I and J the two operating-studs'on the end of the usual carriage. y

The sliding rod E is attached to the side of the mule-head frameAB, and has two mortises or slots, e' e', in which its sustaining-lever G and its operating-lever F, respectively, work, the notched end g of the former sustaining or holdin g the sliding rod E, both in its advanced and retracted positionsl alternately, an d the lever F, passing through the slide E and extend-f ing downward, serves as a means ofadvancing the said slide E, and also of elevatin g the retracting-weight D. The opposite end of the slideE passes loosely through a boss, l, on the lower end of the usual scroll-wheel lever l', and has a head, e2, on its extreme end, whereby the said lever l is caused to lift the usual scrollwheel 2 into gear with its pinion above, when the slide E is retracted by the weight D,which is suspended by a cord over the pulley d', as will hereinafter be described. Also, on the said slide E there is fixed a boss, e3, which has a short arm extending upward, and servin'g to catch against the horizontal arm a of the cranklever n2, which supports the upper end of the beveled roll-wheel o, and thus throws the latter into gear as the said slide E-is retracted by the weight D, as will hereinafter be explained.

The gear-detachin g lever H has one end, h',

pivoted to the frame A B, while its other end is left free to be moved up and down in a guide, h2, also attached to the frame. Fixed to and projecting downward from the said lever H are two curved rigid arms, h3 h4, of such lengths and forms that, as the end c of the carriage C passes, the stud J on the latter will rst strike and pass Linder the arm h3, and thus elevate the lever H sufciently to release the arm a, which is held back against the pressure'of its spring n by means of the stop h5 on the said lever H, and thus throw the roll-wheel o out o t' gear, and immediately afterward the said stud J strikes against and passes under the arm h4, elevates the said lever H sufficiently farther to detach the scroll-wheel lever Z from its contact with a small angular stop, hf", on the said lever, which latter then rests, by the said stop, on the boss l, while at the same time the scroll-wheel Z2, which is supported by the said lever l', falls out of gear. (See the dotted lines in Figs. l and 2.)

The operation of this apparatus in throwing the roll-wheel o and the scroll-wheel L2 out of gear by the advancing or outgoing motion of the carriage G having now been fully described, it remains to describe its operation in throwing the said Wheels again into gear. This is effected by the returning oringoing motion of the same carriage, when its stud I, coming in contact with the retaining-lever G, moves the latter backward far enough to disengage its notch g from its slot in the slide E, and thus permits the weight D to draw back the said slide E, and consequently, by means of its two bosses, e2 e3, to force the two respective wheels Z2 and o into gear, as seen in the drawings.

It will be seen that this apparatus is less complicated than the old one, that it is less liable to derangement by use, and that it is much lighter in weight, more durable, and costs less for construction and application, While it is equally if not more reliable and ei'- eient for the purpose.

I do not desire to confine myself in its construction to the use of the weight D for retract ing the slide E, and thus bringing the Wheels l2 and o into gear, as it will be obvious that a strong spring will answer as an equivalentfor the same purpose,althongh I prefer the use of the Weight, as set forth; but,
