IMPROVEMENT IN HAND-SPINNING MACHINE.

TO ALL IT MAY CONCERN:

Be it known that 1, JAMES M. HART, of Des Moines, in the county of Polk, and State of Iowa, have invented a new and improved Hand-Spinning Machine; and I do'hereby declare that -the following is a full, clear, and exact description thereof,-which will enable othersskilled in the art to make and use the same, reference'heing had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a plan or top View of my improved hand-spinning machine.

Figure 2 is a front elevation of the same.

Figure 3 is an end view, with part of the framing broken out to show the interior parts.

Similar letters of reference indicate like parts.

This invention relates to a new and useful improvement in the construction of a machine for spinning wool or cotton yarns or threads, the object of which is to spin by hand a number of threads at a time instead of a single thread, as with the common domestic spinning-wheel. It consists in an arrangement of driving-pulleys or drums, worked by a crank connected by a self-acting clutch with feeding-rolls which are so arranged and operated as to move to and from a setof spindles for the purpose of supplying the fibre to be spun, and allowing the thread to be wound upon the spindle, the operationbeing similar in principle to that of the mule in spinning with machinery actuated by steam or other power. The machine is simple and easily managed, and for domestic use will be much more useful than the common spinningavheel, as one person can do much more work with it in the same time. p

A represents a strong square orrectangular frame, for supporting the machinery. On one side of the frame is a set of spindles, a a, arrangedin the ordinary manner on a cop-rail, B, stepped at the foot in a side rail, 0, and connected by bands, I; b, with driving-pulleys or drums, M M, made fast on a horizontal shaft, e, upon one end of which shaft is a crank, D. On the top of the frame A is placed a sliding carriage, E, which travels in grooves made on the inside of the two opposite toprails F F, and upon this sliding carriage E are mounted two horizontalfeed-rolls d d, placed one over the other. The top feed-roll 01 carries a pin-ion, c, on the end of a short shaft projecting through one side of the travelling carriage E, which pinion works in a flat,

straight rack, e, that is supported-on spiral springs g g lengthwise on one of the top rails F, and held in place by guide-pins h 7!. at the ends. Between the drums or driving-pulleys M M, a ratchet-clutch, G, is set upon the crank-shaft c to connect with one of the drums, and rotate when the shaft is turned in one direction, and wind up a band, 7:,upon a reel forming a part of the clutch, and thus operate the travelling carriage E, to which it is attached, as hereinafter explained. Connected with the clutch G is a shifting-bar or lever, H, fig. 3, for throwing it in and out of gear. The lever H is made fast, in or near its middle, to the top of a centre post, H, which works the clutch G when it turns by means of an arm, H the end of which arm moves in a grooved wheel, m, on the outside of the clutch, and thus shifts it back and forth on the shaft 0 to throw it in and out of gear. The lever- H is also made curved, or in the form of a bow, as shown in fig. 1, so that the ends projecting inward shall come in contact with a fixed pendent piece, I, attached to the travelling carriage E, when it approaches the limit-of its movement in both directions, by which means the lever His operated to throw the clutch G in and out of gear at theright moment in the operation of spinning. i

In the operation of this machine for spinning, when the carriage E is placed forward on the side next the spindles a a, and the clutch G is in gear with the drum M, by turning the crank D and revolving the drums M M, motion will be given to the spindles, and.at the same time the carriage E will travel away from the spindles, being drawn by the band It as it is wound upon the reel on the clutch G. So soon as the carriage E begins its movement away from the spindles a a, the pinion e engages in the rack e, and turns the upper feed roll 11 as the carriage travels back, until it reaches its opposite limit, when the pendant I strikes the lever H, and throws the clutch G out'of gear. The'carriage E then runs forward to the front again by means of a weight attached to a cord, as indicated in red, fig. 3. When the carriage E moves back from the spindles, the foodroll at turns, as stated, and, operating by friction on the lower food-roll d, the wool, or other material to be spun, is delivered by the rolls to form the yarn as they rotate and recede with the carriage from the spindles which twist it. The rack e is in gear with the pinion e, and the rolls d d revolve only when the carriage E moves away from the spindles. The rackis held down, so that the pinion cannot engage in it when the carriage moves forward towards the spindles, by means of a pivoted pendent, s, on the side of the carriage E, which then catches against a pin, n, and hangs vertically, so as to bear upon the top of the rack, and depresses it against the spiral springs gg, but the rack rises the moment the carriage moves away from the spindles, as then the pendent s is thrown up against another pin, n, and the rack rises by the action of the springs gg, thus engaging the pinion e in the rack. Back of the spindles a a is a rod or bar, 1) 10, extending across the frame A on a level with the ends of the spindles and the line of junction of the rolls d d, for supporting the threads as they are spun; and suspended to an axis, q q, in front of the spindles, is a vibrating r od, 1'7, also extending across the frame and between the supporting rod 1) p and the spindles, for the purpose of depressing the threads-and winding them on the cops, while the carriage E is returning to the front of the machine.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The arrangement of the clutch G, driving pulley or drum M, shifting-lever H, pendent piece I, the band K, and the carriage E, operating substantially as and for the purpose herein described.

2. The spring rack e and pinion e, in combination with the feed-rolls d d, the carriage E, the clutch G. and the shifting-lever H, arranged and operating substantially as and for the purposes herein described.
