T 0 all whom it Tit/Ly con/eerie.-

Be it known that 1, CHARLES E. LOMBARD, a citizen of the United States, residing at East Wilton, in the county of Franklin and State of Maine, have invented certain new and useful Improvements in Spinning and Twisting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use same, reference being had to l the accompanying drawings, and to the letl ters and figures of reference marked thereon, which form a part of this specification. l

This invention relates to new and useful l improvements in apparatus for spinning and twisting yarn, and comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described and then specifically defined I in the appended claims.

I illustrate my invention in the accompanying drawings in which:- v

Figure 1 is a side elevation of my twisting and spinning apparatus. Fig. 2 is a vertical 1 sectional view through the bobbin and rotatable shafts. Fig. 3 is a detail view of a camactuated adjusting screw, and Fig. 4 is an edge view of the construction shown in Fig. 3.

Reference now being had to the details of the drawings by letter, A designates a frame having standards A in which a shaft B is journaled in suitable bearings having a bobbin 0 fixed to rotate therewith.

D designates rollers between which the yarn D is fed, said rollers being operated by any suitable power mechanism.

Loosely mounted upon the shaft B are the grooved pulleys E which are connected together by means of the rods E. Fixed to one end of a rod E is a hook F over which the strands of yarn to be twisted are adapted to pass. Corresponding ends of the rods E are fixed to a ring G mounted loosely upon the shaft.

H designates a graduated pulley which is fixed to the shaft B, and I designates a hollow shaft loosely journaled upon the shaft B and to which the pulleys E are fixed.

K designates a shell which is swiveled to the shaft I and is held in position by means of the collars K, one upon either side thereof and which are fixed to the shaft 1.

N designates a shaft mounted in bearings N upon said frame and has an angle lever O fixed thereto, one arm of which is pivotally connected to a link ference of said cam.

Q which in turn is pivoted to the shell K by means of a pm Q. The other arm of the angle lever is pivotally connected to a plunger P by means of a pivot pin P, said plunger having a longitudinally slotted portion P to the lower end of which is pivotally connected a nut J having a threaded aperture therein to receive the screw J. The upper end of said screw has swiveled thereto a collar J held in place by means of a nut J 1t designates a shaft having a heartshaped i cam it fixed thereto, said shaft it being mounted in suitable bearings and driven by any suitable power. R (.lesignatcs a pivoted standard carrying a pivot pin R at its upper end to which the cam-actuated lever it is pivotally connected. Said lever it has pivotally mounted thereon an anti-friction wheel it adapted to travel upon the circum- The other end of the lever R is forked and carries pivotal screws 1', one in each arm of the fork, which screws 1' are mounted in apertures in the shell J S designates a ratchet wheel which is mounted upon the screw J and is adapted, as an intermittent movement is imparted to said Wheel, to cause the screw to move in one direction or the other amordingly as the wheel is moved in one direction or the other.

Pivotally mounted upon a pin T carried by the standard T is an angle lever T, one end of which is pivotally connected to a pawl T'" adapted to ride upon the teeth of the ratchet wheel S. The other arm of the lever 's pivotally connected to the lever it by means of the link T. A spring \V is fixed at its lower end and its upper end is fastened to the lever R and is provided for the purpose of returning the lever it to its normal position after having been raised by the plunger.

The under surface of the gear wheel S has teeth S projecting therefrom which are in mesh with a pinion wheel S mounted upon a stub shaft, and S is a handle fixed to said stub shaft whereby the pinion wheel S may be rotated and return the screw to its lowest position after having been raised to its highest position.

The operation of my apparatus is as fol lows. The rollers D being operated by any source of power, are caused to feed the strands of yarn toward the bobbin, and the rotary movement of the pulleys E, which are driven by belted connections with a driving shaft, will cause the strands of yarn to be twisted and cam-actuated means for imparting an in the same longitudinally, as set forth.

by the hook F rotating rapidly with said pulleys and the rotary movement of the shaft i which is driven by the pulley H which is also connected to any suitable driving shaft, will 8 cause the twisted yarn to wind upon the bobbin. In order to cause the twisted yarn to wind uniformly upon the bobbin, the pulleys E to which the hook F is fastened l are given a slight intermittent longitudinal l movement through the medium of the cam driven mechanism which causes, at each revolution of the cam, the lever R to tilt, the plunger to be raised, the shaft N rocked and x the angle lever fixed thereto to impart a slight movement to the shell K. After the lever R has been raised to its highest limit and a further rotary movement of the cam R, the lever B will be drawn down by means of the spring WV, to its normal position. It will thus be noted that by the continuous rotary movement of the cam carrying shaft, the screw will be gradually fed upward and the hook moved toward the free end of the bobbin. As the twisting apparatus rotates at a higher rate of speed than the bobbin, it will be noted that the strands of yarn will be thoroughly twisted before being wound upon the bobbin.

What I claim is 1. A twisting and spinning apparatus comprising a rotatable shaft, a bobbin fixed thereto, a hollow shaft mounted to move longitudinally upon said bobbin carrying shaft, a shell swive ed to said hollow shaft, a flier,

intermittent longitudinal movement to said flier, as set forth.

2. A twisting and spinning apparatus comprising a rotatable shaft, a bobbin fixed hereto, a hollow shaft mounted to move longitudinally upon said bobbin carrying shaft, a shell swiveled to said hollow shaft, a flier, a rock shaft, an angle lever fixed to said rock shaft, pivotal connections between one arm of said lever and said shell, a longitudinally movable screw, a nut mounted upon said screw, pivotal connections between said nut and angle lever, and cam-actuated mechanism for rotating said screw and mov- 3. A twisting and spinning apparatus com prising a rotatable shaft, a bobbin fixed thereto, a hollow shaft mounted to move longitudinally upon said bobbin carrying shaft, a shell swiveled to said hollow shaft, a flier, a rock shaft, an angle lever fixed to said rock shaft, pivotal connections between one arm of said lever and said shell, a longitudinally movable screw, a nut mounted upon said screw, a plunger pivotally connected to 1 said angle lever and also to said nut, camactuated means for moving said plunger, and mechanism for imparting an intermittent movement to said screw, as set forth.
