HENRY A. OWEN, OF VHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THE WHITIN MACHINE WORKS, INCORPORATED, OF SAME PLACE.

TRAVERS-E-MOTION FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 637,019, dated November 14, 1899.

Application led May 18, 1899. Serial No. 717,297. (No model.)

To all whom it may concern,.-

Be it known that I, HENRY A. OWEN, of Whitinsville, in the county of Worcester and State of Massachusetts, have invented a new Y and useful Improvement in Traverse-Motions for Spinning-Machines;- and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

In spinning-machines the roving in its passage from the spools to the drawing-rolls is controlled by a trumpet mounted on a rod lto which reciprocating motion is imparted,

whereby the roving is guided in its passage through the drawing-rolls to continuously Lrolls, while it wasV distributed over a greater length of the rolls, caused the rolls to wear at the extreme ends, as the traverse always stopped at the same place, and the vdwell caused by the natural reverse motion made this Wear more at these places.

The object of this invention is to impart an ever-changing reciprocation to the traverserod and prevent the dwell of the reciprocation at the extreme ends of the traverse and the consequent greater wear ofthe rolls, particu# larly the top rolls, at the ends of the reciprocation.l

The invention consists in the peculiar and novel construction of the traverse motion whereby the reciprocation of the traverserods and the trumpet, and thereby the path of the roving through the drawing-rolls, is continuously changed and the ordinary defect of the dwell of the traverse at the extreme end of the throw of the cam is corrected.

Figure lis a transverse sectional view showing the drawing-rolls and top rolls and the mechanism for reciprocating the roving traverse-rod operated from the back drawing-roll. Fig. 2 is a side view of my improved traverse- In traverse-motions of this construcmotion. Fig. 3 is a sectional view on the line A A of Fig. 2. Fig. 4 is a sectional View on the line B B of Fig. 2. Eig. 5 is a diagram illustrating the path of the roving controlled by the reciprocation of the trumpets on the traverse-rod.

Similar letters of reference indicate corre spending parts in all the figures.

In the drawings, A A indicate the drawingrolls; A', the back roll; B B B, the top rolls; C, the traverse-rod, and C C the trumpets on the traverserod; A2, a worm on the back roll A; A3, a bracket secured to the front beam or other convenient stationary part of the spinning-machine; A4, a slotted arm eX- tending upward from the bracket A2, and A5 another slotted arm extending vertically from the bracket A3. The arms A4 and A5 are preferably made integral with the bracket A3. In the slot of the arm A4 the stud D is adjustably secured, and on this stud is pivotally supported a bell-crank lever, the arm D of which forms the support of the stud D2, on which the worm-wheel D3 and the cam D4 are journaled, as is shown in Fig. 3. The stud D may be adjusted in the slot ot" the arm A4, so

as to bring the worm-wheel in proper mesh with the worm A2 on the back roll A. The frame D5 is secured to the traverse-rod C and is provided with the pins D6 D6 on the opposite sides of the cam .D4. The distance between the two pins D6 D6 and the shape of the cam D4 are designed to insure contact of the cam with the pins during the whole of the revolution of the cam. The frame D5 is preferably provided with the slot D7, through which the end of the stud D2 extends. A spring-pin may be inserted in the end of the stud D2, as is shown in Figs. 1 and 2. The arm D8 of the bell-crank lever supports the stud D2, on which the gearDwis journaled. The gear D10 meshes with the worm-wheel Da and is provided with either a greater or less number of teeth than the worm-wheel D2. The gear D10 is provided on its outer side with the eccentric-disk D11, which extends into the upper end of the arm D12, the lower end of said arm being secured in the slotted arm A5 of the bracket A2. p

When my improved traverse-motion is secured to a spinning-machine, the worm on the IOO back roll imparts rotary motion to the wormwheel D3 and to the cam D4. The cam, acting on the pins D6 D0, im parts reciprocating motion to the traverse roving-rod and the trumpets. The worm-wheel D3 transmits its motion to the gear D10, and the eccentric D11, rotating within the arm D12, pivotally secured at its lower end to the slotted arm A5 of the bracket A3, imparts a rocking motion to the bell-crank lever forming the supports for the worm-wheel D3, the cam D4 on one arm and the gear D10 on the other arm, wherebyat each revolution of the gear D10 the bell-crank lever, the gears, and the cam supported by the bell-crank lever are made to oscillate.

In the drawings the gear D10 is shown provided with one more tooth than the wormwheel D3. If the number of teeth in these two gears were equal, the oscillation of the bell-crank lever, the cam, and the gears would continue to be equal. As, however, the num- 'ber of teeth in the gear D10 is designed to be either greater or less than the number of the teethin the worm-wheel D3, the oscillation of the bell-crank lever and the cam is continually changing in its extent and the path of the roving controlled by the trumpets C' C continually changed in its traverse and its passage through the drawing-rolls.

In the diagram shown in Fig. 5 the lines E E indicate the normal traverse of one of the trumpets on the roving-rod produced by the rotation of the cam, and the lines F F indicate the extreme limit of the traverse of one of the trumpets produced by the oscillation of the bell-crank lever and the cam carried by the same, the difference between the lines E E and F F being the traverse produced by the eccentric D11 in excess over that of the cam D1.

In my improved stop-motion we have, first, the reciprocation incident to the action of the cam on the frame secured to the rovingrod; second, the oscillation of the bell-crank lever caused by the eccentric D11, and, third, the Variations of this reciprocation caused by the difference in the number of the teeth of the gear D10 and the worm-wheel D3, whereby the roving controlled by the trumpets is made i to pass between the drawing-rolls and top rolls to continually-changing points, and the wear on the drawing-rolls and top rolls is reduced to a minimum.

I-Iaving thus 'described my invention, I claim as new and desire to secure byLetters Patent- 1. In a traverse-motion for spinning-machines, the combination with the back roll, a worm on the back roll, the traverse-rod and a frame secured to the traverse-rod, of a worm- Wheel engaging with the Worm on the back roll, a cam connected with and rotating with the worm-wheel, projections on the frame secured to the traverse-rod acting on the cam, andv a bell-crank lever one arm of which supports the journal-bearing of the Worm-wheel and cam, the other arm supporting the journal, of a gear in mesh with the worm-wheel, an eccentric on the gear connected with the worin-Wheel and an arm surrounding the eccentric and connected with a fixed part of the machine; whereby reciprocating motion is imparted to the traverse-rod by the cam and oscillating motion to the cam, as described.

2. In a traverse-motion for spinning-machines, the combination with the back roll, a worm on the back roll, the traverse-rod and the frame secu red to the traverse-rod adapted to be operated by a cam, of the bracket A3, the slotted arms A4 and A5 on the bracket, a bell-crank lever supported on the arm A4, the worm-wheel D3 and cam D4 supported on the arm D of the bell-crank lever, the gear D10, the eccentric D11 projecting from the gear D10 and the arm D12 inclosing the eccentric D11, the lower end of the arm D12 secured to the arm A5 of the bracket; whereby the normal reciprocation imparted by the cam D4 is increased by the oscillation of the cam and varied by the changing position of the rotating eccentric D11, as described.

In witness whereof I have hereunto set my hand.

HENRY A. OWEN.
