GEORGE CROWTHER, OFPHILADELPHIA, PENNSYLVANIA. VLam Patent .Na 61,723, ma February 5, 1867.

IMPI!OlddlllllA IN SPINNING MULS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORG-E Cnow'rnsn, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in'Spinning Mules; and I do hereby declare that thefollowing is a full and exact descriptionl thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. l

The nature of my invention and improvement mainly consists in giving an automatic inward motion to the carriage by means of belts and pulleys combined with the rimlshaft, and Winding the' yarnon the bobbins or spindles at the same time ;v it also consists in a new construction and arrangement of the backcatch for stopping the shifter and holding it securely during the time it should remain on the loosepulley 6, on the driving-'shaft C.

I am aware that there are modes of giving'au automatic inward motion to lthe carriage, but' they are of a complicated nature and liable to get ont of order,`while mine is simple and not easily deranged. With its use a man can operate a much larger mule than ordinarily. In the accompanying drawings* Figure 1 represents a plan or top view of the improved mule.

Figure 2 is a front elevation of the same.

Figure 3 is a side view of ditto.

Figure 4 is a face view of the pulley 1 1 in connection and detached from the rim-shaft.

Figure 5 is a face view of the back-catch.

Figure 6 is a side view' of the lever N.

A is the standing frame, which hasrall the parts in connection therewith of an ordinary mule. But as these parts are Well known to'those skilled in the art to which my improvement appertains, I will only describe such parts as Vare connected with the improvement. Y 'B is the carriage, similarly constructedandarranged in relation to the standing frame A, as thefcarriage of an ordinary mule.- C is the rim-shaft, on which I place thepulley I, which has4 aiilat part, 1', connected therewith by means ofthe sleeve D, that turns freely on the driving-shaft C. This pulley is shown detached in iig. 4. A loose pulley, 2, is placed on said sleeve before fastening the part 1 to the sleeve. The said pulley 2jh`as a groove for the reception of the belt-G, anda. hat part, a, to receive the driving belt C at which time thesad belt also comes over the at-partl of pulley 1. There are' pulleys, 3 and 4, on the shaft E, the former being fast on the shaft and the latter 'turning loosely thereon. Pulley 3 is connected with pulley 1 by means of the cross-belt F, to revolve the shaft E, and 'give the inward motion to the carriage, said shaft being connected with the drawing-cord e by' means of the pulley 3 on the end of the shaft. The loose pulley 4 has two grooves in its face, one for `the reception of theopen` belt G, which also connects with pulley 2, the other receives the cross-belt. I, which makes a further connection with pulley 5, on the twistshaft J, to wind the yarn on thebobbins or spindles, the intermediate parts between the shaft and the spindles being constructed and arranged in the usual manner. For holding `tbe shifter K in place when the driving-belt C is on the loosev pulley 6, I construct the back-catch L, with the shoulder', as seen in iig. 5. The said backe catch is `jointed at its rear end to the upper end of the vertical rod M, the lower end of which is jointed to the short end of the horizontal lever N, whose fulcrum-pin c is held by lugs on the under side of theI cross-bar 0,

to which the standard P of `the shifter is secured. Near the 'front end of' the lever N there is a lug, d, underV which the adjustable rod Q, which projects from thc carriage,` passes in the .back motionvot` the latter, to raise the shoulder of the back-catch above the shifter handle in the outward motion of the saine., When the said rodA has passed the lng the forward end of the lever N falls., 'which action raises the'vertical rod M, and causes' the front end of the back-catch to descend and catch over the handle of the shifter and hold'it in place wliile the carriageshould remain out. And when thcoperator has started the carriage inwards, and the 'rod Q, which projects therefrom, passes under the lug or projection d, of the lever N, and raises the front end of t the lever, the rear end thereof in its downward motion, by causing the rod M to descend, operates the back-catch L, and disengages the shoulder b from the shifter, and th'e latter is then instantaneously operated by the spring R, acting through its nsuaLconncction and the driving-bclt C is broughtover'the iat faces 1 and a, of the pulleys 1 and 2, which, acting` through the belts 'and' pulleys above-described, revolve the shafts E and J, and give an inward motion to the carriage, and wind the yarn on the bobbins or spindles, atrthe same time thc shaft E, being connected with the carriage as above described, and the shaft J, operating the spindle by means of the usual intermediates. During this operation,.in' consequence of the usual connection of the twist-shai'td' with the driving-shaft, for the purpose of revolving the former shaft, to givev motion to the spindles to spin the yarn, thelatter shaft is also partially revolved, but this is obviated by a blank in the toothed Wheelf on the end of Athe shaft.

Having thus fully described my improvement in spinning mules, whatv I claim therein as new, and desire t0 secure by Letters Patent, is-Q I v 1. The combination of the loose pulleys 1 and 2, constructed and applied as desoribed, with the driving-shaft C, for giving the inward motion to the carriage, and winding the yarn'on the spindles, the said pulleys acting through the pulleys 3 and 3', the band FA, and cord e, for giving an inward motion to thecarriage, and the pulleys 4, V5, 7, 8, and 9, and bands G, I, R, and S, or their equivalents, for .operating the spindles, as above set forth.

2. `The combination of pulley 1 with pulley 3 by means of' the cross-belt F, `for operating the shaft E, substantially as described and for the purpose specified.

3. The oombination of pulley'2 with pulley 5, on sha-ft J, by means of the intermediate double pulley 4, and belts and I, for operating said shaft, substantiallyin the manner-.described and for the purpose specified.

4. Constructing the back-catch Lwith the shoulderv b, and combining with said catch the verticatrod M, lever N, and rod Q, or its equivalent, the said parts being arranged for joint .opel-ation, substantially'as described and for the purpose set forth.

:ln-testimony that the above is my invention I have hereunto set my hand andvaixed my seal this 5th day of July, 1866. p

GEORGE GROWTHER. [1...
