SPECIFICATION forming' part of Letters Patent No. 400, 502, dated April 2, 1889.

Application filed October 9, 1888. Serial No. 287,609. (No model.)

.To a/ZZ whom t may concern:

Be it known that` we, SAMUEL SMITH, of Lawrence, in the county of Essex, State of Massachusetts, and RICHARD GILI'., of Methuen, in the county of Essex, State of Massachusetts, have invented a certain ,new and useful Improveinent in Spinning-Spindles, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation of our improved spindle, the rails being shown in transverse Vertical section; and Fig. 2, a vertical section of the same, the spindle proper and certain other parts being shown in side elevation.

Like letters and ligures of reference indicate corresponding parts in the different iigures of the drawings.

Our invention relates to that cl-ass of spindles which are provided with fliers and designed principally for worsted-spinning; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a more effective and otherwise desirable device of this character than is now in ordinary use.

The nature and operation of the improve- Inent will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the stationary or bolster rail, B the lifting-rail, and C the spindle proper, these parts being all of the hereinafter set forth.

`A step,D,having its lower end threaded, as shown at m, is secured in the rail B by anut, E, the upper end of said step being provided with a socket for the reception of the lower end of the spindle C, and exteriorly screwthreaded to receive-an oil-cup, F, and checknut G, said cup being provided with a screwthreaded hole in its bottom for the reception of the upper portion of the step.

A bracket, H, projects from the step' D, and fitted to slide in a hole in said bracket there is a rod, I, pro vided with a nut, 45, at its outer 4end and with a head, 47, at its inner-end, said head having a horizontally-aman ged notch or groove, 50, in its face, which is V-shaped in cross-section and provided with a friction-pad adapted to engage a fixed collet, J, on the spindle C, the periphery of said colletbeing reversely V-shaped in cross-section and adapted to iit the V-shaped groove in the head 47.

A coiled spring, K, is disposed on the rod I between its head 47 and the bracket H, said spring acting expansivel)` to force the head against the collet .I lon the spindle C, thereby retarding the movement of the spindle in accordance` with the pressure of the spring, the object of the nut 45 being to overcome the action of the spring, and thereby regulate the movements of the spindle as desired. A bolster, L, has its lower end, 65, secured in the stationary rail A by a set-screw, 75, said bolster being bored vertically to receive the spindle C and provided with a recess, 85, for receiving therwhirl N. The upper portion of the spindle-hole in the bolster L is counterbored or enlarged to receive a vertically-arranged sleeve, O, through which said spindle also passes, and to which the whirl N is secured within the recess 85.`

Secured to the upper end of the sleeve O, above the bolster L, there is a disk, P, and mounted-on said disk there is a thin metallic cylinder, Q, having a ring, 14, secured thereto near its top.

Two vertically-arranged Hier-arms, R, one

Crescent-shaped slots 54 are formed at in` tervals in the lower portion of the cylinder Q,

through which the oil may-pass should any gather in said cylinder. The slots also permit the passage of air through the cylinder, and tend to cause a uniform current of air around the bobbin as the cylinder is revolved,

IOO

which current tends to lay the iibers of the yarn more evenly and subserve to equalize the currents of air in the cylinder as it is revolved, and thus lay the fibers of the yarn to better advantage than when they are not employed.

The slots 5l may be made in any equivalent shape to perform the same function, although we deem the crescent-shaped openings preferable, as we have found that, for some reason which we do not fully understand, they accomplish better results than openings of a dierent shape.

A pad or ring, 6i, composed of felt or other similar absorbent material, is disposed in the cup F, said. cup being designed to contain the oil for lubricating` the spindle in the step D, and the ring to prevent the oil from being thrown from the cup by the centrifugal action of the spindle, and also to absorb the oil and deliver it gradually to the spindle, thus enabling less oil to be used than when the ring is not employed. The cup F and pad 64: also enable friction to be applied to the spindle independently of the friction device mounted in the bracket II in case said bracket should at any time become broken or the rod I be removed, the same being accomplished by turning the cup upward until its pad 64 presses with the requisite force 011 the collet J, and securing it in that position by the check-nut G, said nut not being required in most instances. Both ot the friction devices may also be readily used in conjunction by so constructing the head of the rod I and the cup F that said head and the pad in the cup may both be brought to bear on the collet .I at the same time.

It will be understood that one of the flierarms R is not a working-flier, and is employed merely to counterbalance the other. The

working-nier may, however, be counterbalancedin anyothersuitable manner, if desired.

Having thus explained our invention,what we claim is- `l. The lifting-rail B, the spindle-step D, se- -cured to said rail by the nut/E and exteriorly screw-threaded at its upper end, the oil-cup F, having a screw-threaded hole at its bottom and mounted on the step D, and the felt ring G4, disposed in said cup, in combination with the spindle C, resting in said step and provided with the collet J, whereby friction may be exerted on the spindle by turning said cup upward to bring said ring in contact with the collet and the movements of the spindle thereby regulated, substantially as set forth.

2. The lifting-rail B, the step D, secured in said rail and provided with the bracket Il, the upper portion of said step' bein g exteriorly screw-threaded, the oil-cup F, having a screwthreaded hole in its bottom and mounted on said step, the pad or ring G4, disposed in said cup, and the rod I, iitted to slide in said bracket and provided with the nut 45,spring K, and head 47, in combination with the spindle C, provided with the collet J, substantially as described.

3. The cylinder Q, provided with an opening or openings through its side, in combination with thedisk P, sleeve U, whirl N, spindle C, and Hier-arm R, substantially as described.

4. The cylinder Q, provided with one or more crescent-shaped or curved openings, as 54, in combination with the disk P, sleeve 0, whirl N, spindle C, and Hier-arm R, substantially as described.
