SPECIFICATION forming part of Letters Patent No. 377,426, dated -February 7, 1888.-

Application filed April l, 1887. SerialNo. 233,283. (No model.)

To .all whom tn/tay concern.-

Beit k uown that I, JAMES ALBERT FARMER, of South New Market, in the county of Rockingham and State of New Hampshire, haveinvented certainv new and useful ,Improvements in Spinning-Spindles and Supports Therefor;

and I do hereby declare that the following is ar Q full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon,which form a partof this specification.

My invention relates to a special construction,which will lfully-appear from the description and claims. I

In the drawings, Figure yl is an elevation of the spindle and its supporting devices complete,with the bobbin in place on the spindle; Fig. 2, a vertical sectioniof the same, showing the spindle in elevation.

The supporting-case A, which by its construction serves also as a bolster, having top and bottom bearings for the spindle B, ismade as follows: k

Vithin a tubular bore, c, of substantially uniform diameter, made in this supporting-case A, but not extending clear through its lower end, is secured at its bottom a bottom bearing, d, made of composition metal of the kind usually employed for spindle-bearings in spinning-machines, to receive the tip 'of the spindle and serve as its step-bearing, and within the same bore at its top is iixedly secured a tubular top bearing, e-say of about an inch in lengthmade of composition metal,and adapted to snugly receive and support the spindle at y that point, while permitting its Yfree revolution by means of its whirl f. This top bearing, e, projects above the bore c, and has around such projecting end an annular oil space or chamber, g, between the part e and an upward projection, h, on the supporting-case, this part h having at its top an annular rim, t', as shown.

The shoulderj,which may rest on the rail of the spinning-machine, has a shallow groove, k, on its upper face, and from this groove one or more small oil ducts or passages, Z, incliney downward and lead into the annular ,space or chamber g. Other oil passages or ducts, m,

bearing, e, thus carrying the oil into direct l are made through the composition tube or top I contact with the spindle and the inner surface f of this bearing, and allowing it in any desired quantity to pass into or to vfill thelarge oilchamber -n between the two bearings d and-'6,

and also to lubricate the step-bearing d. The

whirl f is made with a cavity, o, on its under side to receive the rim t', and a small screw, p, k

in the ring p of this cavity serves to fasten the spindle down into its step, but yet leave the same free to revolve,-this screw projecting be` p neath the rim. `This rimtis of such height relatively to the depth of the cavityo that when the spindle is in place in its stepbear ing d the top of the rim does not come in contact with the bottom ofthe cavity; vhence needless friction from any such cause is avoided.

I prefer to put a nut, q, on the step, 'as

shown, for the purpose of fastening thesup- 7.0 n Vporting-case into the frame, so as to permit of its being adapted for and secured to railsof different sizes or thickness.

ser-ves to adapt the supporting-case A to rails of differentthicknesses.

The turning of Y this nut in either direction, as may/be needed,

, t will now be seen that even when the spin- *y dle is in place or is running, oil can be pouredl Y,

into the groove k, and which, passing through the ducts Z,will first enter'the annular chamber or space g, and thence, by the ducts m, enter be-.

tween the fixed top bearing, e, and the spin, dle, and thence iiow ydown into the spacious chamber n, and thence to the cavity vo in the step-bearing d. fr

It'willalso be seen that a plentiful supply of oil can be poured in, which will last a long time, as there is no chance of leakage vor escape at the bottom of the case, because such bottom is integral and has n o joint and no outlet, and that the centrifugal action cannot throw Y out or waste the oil at the top, because any such 'tendency would merely carry the oil throughl the ducts m into'the annular space g, the boty tom of which is lower than the annular groove la. It will also be seen that the screw p holds the spindle in its proper relation t'o the step f and its bearings yand. prevents any accidental rising or displacementof the spindle, whileit permits its ready removal at any time.

The upper bearing, e, being welded or permanently fixed to the supporting-oase, cannot shift its position, and therefore cannot in anywise affect or alter the true vertical alignment and proper working of the spindle if the supporting-case itself be placed correctly. Thev advantages of employing composition metal for this upper bearing, as well as for the lower bearing, will be readily understood by those versed in the art.

My combined bearing performs the duty both of a step and of a bolster, avoiding the disadvantages of having them separate, and also affording a cheap and ecient construction.

The spindle below its whirl'has a very gentledownward taper, so that when any wear takes place at its bearings, if the spindle in consequence lowers a trifle, this wear is automatically adjusted or compensated for.

I claim- 1. The supporting case described, having the xed tubular top bearing, e, as described, the rimmed portion h i, the annular chamber g betweenthe parts e and h, the groove k, ducts l and m, oil chamber n, and the stepbearing d, all substantially as set forth.

2. In combination with the supporting-case A, having the top and bottom bearings, e d, chamber g, rim h t', groove k, ductsl m, and oil-chamber, as set forth, the spindle provided With the whirl and screw p, as and for the purposes set forth.

3. The case A, having its lower and closed end made integral with the body of the case and its top and bottom bearings, e d, inserted therein from the top, and provided with chambers g n, rim h t', ductsZ m, and groove 7c, all as and for the purposes set forth.

JAMES ALBERT FARMER.
