IMPROVMJENT SPINDLE-STEP IR SPINNING-NAMES.

To all whom; tt may concern: Y

Be it known that I, EznK1nn'Br.AKn,'of Chcopee Falls, in the county of Hampden, and Commonwealth of Massachusetts, have invented a new and improved Spindle-Step; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ol' the same, reference being had to the accompanying `drawings, making a part of this specification, and to the letters and gures of reference marked thereon, in which Figure 1 is an elevation of said spindle-step, having the foot of a spindle set therein, and the whole shown as set in the rail of an ordinary spinning-frame;

Figure 2 is a vertical sectional view, the plane of transverse section being indicated by the line Z Z in Figure 3 is an elevation of the cap, which forms the step itself, the cover being removed, and the whole being taken out of the rail, in which it rests when in use;

Figure 4 is a vertical axial section through the line z z, fig. 3; and

rigore 5 is afvemeariial sentieri tnrssgnt'nemp, f

which rests uponv the upper part of. the step, and closely encircles the spindle.

All the aforesaid drawings are full size, and repre-Y sent the step, rail, and spindle, of the size actually employed in manuihctuling-operations.

My invention is designed to be employed upon ringspinning frames, and mayalso be employed in mulespinning. p

The high rate of speed at which cotton-spindles are drivenfrom three to five thousandv revolutions per minute-makes it absolutely necessary that the foot of the vertical spindle, and the socket or step in which it turns as a bearing, should be constantly and thoroughly lubricated and the great friction developed in a dry step, under the high speed, very speedily wears the step so as to render it.useless.

The steps in common use, for the most part, require oiling daily, or at intervals of a very few days, and at the expense of much oil and labor, and of the frequent stoppage of the spinning-machinery, while my invention is designed to be run for several months with a single oiling, such oiling being readily and expeditiously performed.

It has also been estimated that the waste of oil by and by loss from oil thrown out of the step, amounts to about five-sixths of the whole amount of oil applied, leaving but a single sixth to be utilized ln overcoming the friction of the step and spindle, nearly all of which waste is prevented by the operation of my invention, an important gain, not only in an economical point of view, butin point of cleanliness, and also in lessening the liability l to lires from oilsoaked lioors.

A csp is also added to the spindle-step, not to prevent the escupe of oil, which is otherwise provided for, but to keep the cotton-waste, dust, and other foreign matter from getting into the step.

frequent oihugs,

Irim, al a?, which serves :the socket, which opens into This cup, and the upper part of the step, I so shape,

relatively to one another, that the former alwayes ht tightly upon the latter, and always drops into the right position upon the step.

he'cap, therefore, is not supported upon the spindles-nd revolved with it, as iu many covered spindle- I steps, but the stem of the spindlepasses down through a cylindrical opening in the top of the cap, which opening is made just large enough'to allow the spindle- Y stem to turn within it.

The construction of my invention is as follows:

S represents a portion of the rail of a spinning-frame, inwhich is the usual cylindrical opening, H, to receive a spindle-step, ranged in a line along the rail, and held in place by set-screws s. f

1n the ordinary spindle-steps, without a collar at the upper end, such set-screws are necessary to prevent the step from dropping through the rail, but `are not absolutely necessary with steps such as shown in the drawings.

The step itself, A, dricai portion, b, of

is composed of a straight cyliuthe usual diameter of ordinary stepsand aneenlarged portion,- a/,tlaeoutside of -whie is slightly tapering or coni l, so as to make a close lit with the cap, which shuts-down over it.

The enlargement of but serves a more important purpose in aiording room within the step for a capacious oil-chamber, above the top of the rail, and extending up the spindle vhigher rises, thus affording a V than vthe whole step generally much longer socket than usual ber for the foot of the spindle.

The space which the enlarged portion a occupies above the rail is not useful for any other purpose, and

beneath the oil-chamis not occupied at all when the ordiuarysteps are used with their tops risingljust out of the rail.

A thin rim, j' f, projecting inward, eucircls the spindle, so as to close the top of the cup when the spindle is in place, and prevents the yoil from spurting upward when the spindle is dropped into its seat alter.

doing.

The upper side of the rim is made slightly concave or dishing, so that any oil which may follow up on the spindle when in moton, will be guided back into the oil-chamber when the spindle is still.

The angular bottom, e, of the socket is of the ordinary form, and at the usual depth below the top of the rail; f

Above this is the straight cylindrical portion, E', of the roomy oil-chamber E, the shape of which is plainly shown in gs. 2 and 4.

It will be observed that by carrying up the step above' the rail, so as to bring the whole oil-chamber above the top of the rail, the straight passage E' can be much elongated, thus aording a much longer bearing, and keeping the spindle more accurately in its proper vertical position. i The spindle is of the ordinary form, having the conicalV foot e' fitting th'e angular' seat e, the straight cylinthe upper part of A forms a' to support the step in the rail,

there being many of these steps arl drical portion B' nearly lilling the part E of the socket,

and a swell at the upper part of the oil-chamber, ending in the full-sized spindle-stem B, above the swell.

It is desirable that the upper edge 'i i ofthe swelled part shall fall a little below the lim f f, so that the oil will be deflected from the annular space between the rim ff and the spindle B. The inner sides of thc cap O are made slightly flaring, so as to correspond with the taper of the sides a* a2 of the step; and a circular opening, c, is made in the top of C, which is closely fitted by the stem B of the spindle. I l y If the conical form of the outside of the enlarged part-a of the step, and the inner side of the cap C, have the same axis as the step A, then the cap will always settle down evenly upon a, and the opening c, in-the top of the cap will be in correct position to receive the vertical spindle B, without binding or crowding it, and make nearly an air-tight joint about the top of A.

The step A and the cap 0 may be made of .brass, iron, or other metal, which will withstand the r wear of `the foot of the spindle.

- The operation of my invention is' as follows:

The step being set in its socket in the rail, and the spindle standing within it, the cap C is lifted off from the step, and the spindle raised a fraction of an inch, say one-fourth, so as to bring the smaller part, B', of the spindle above the rimf f. There will then be space to insert the nose of an oil-can between the spindle B and the rim f f, and ll or nearly lill the empty space in E E' ande with oil. The spindle can then beI dropped back into its seat, and the cap O replaced upon A. A slight pressure will make the liaring cap fit very tightly upon A, while the rounded form ofthe outside of O allows nb waste or threads to catch'and wind up around the cap.

At the very high speed at which such spindles revolve, as before specilied, the centrifugal force repels the oil from the spindle, and piles it up against the sides of the oil-chamber E, the rim f f preventing it from running upward ont of the chamber. When the spindle is stopped, the oil will run back about the spindle, penetrating down into the foot e and straight part E' of the step.

By comparative tests, vit 1s estimated that the supchambers of limited capacity, and made withoutv any enlargement of the step, and below the top of the mil,
