SPINDLE AND BEARING THEREFOR.

SPECIFICATION forming part of Letters Patent No. 247,522, dated September 27, 1881.

l Application filed November 17, 1879.

To all whom it may concern Beit known that I, JAMES C. STANLEY, of New Hartford, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Spindles and Bearings Therefor, of which the following isa specification. My invention relates to spindles and bearings therefor, and particularly to that class of bearings in which both the step and bolster are connected with a reservoir from which oi is supplied. f

The object of my invention is to provide means whereby a spindle shall be regularly and continuously supplied with oil withoutat any time having much more delivered to it than is required for perfect lubrication. I attain this object by the mechanism illustrated in the 4 accompanying drawings, in which- Figure l is an elevation, partly in section, of a reservoir-spindle and adjacent parts ofmy improved construction. Fig. 2 is a modification of the sleeve shown in Fig. 1. Fig. 3 is a sectional view, with the spindle removed, of the sleeve and case seen in Fig. 1.

A is the spindle, having the whirl B, which has upon its lower edge the ange b, which has upon its outer edge the downward project-inglip, c. c2 is a lip attached to the whirl nearer the axis of the spindle, thus forming an inverted annular cup, d, whose edges overlap the lip e, which extends upward from the case D. This case has formed upon its top by the lip e the cup e', annular in form, theinner rim of which is formed, when the parts arein poi sition, by the bolster-sleeve d3, which extends above the case D, the outer rim .by the lip e, and the bottom by the top end of the case and the top of the iiange on the bolster sleeve. This cup receives all the voil overiiowing the bolster-bearing, as hereinafter described, and prevents waste.

H is a sleeve,comprising the bolster and the step, h being the bolster or part of the sleeve upon which the spindle bears near the whirl, beginning at the point marked w and extending upward, and being the step in which the lower bearing of the spindle moves.

The sleeve H and case D are so formed that between them will bean oil-chamber, n, which is filled with any suitable fibrous material, to filter the oil permitted to enter it or to limit the capacity of the inducts, hereinafter described. Around the upper end of the sleeve is formed a ange, j, to retain it concentric with the case D in an aperture in which it is placed, which aperture is for the greater part of the depth ofthe case made of considerable greater diameter than the sleeve, and at its extreme lower end only of such diameter as will permit of the introduction of the sleeve. There will, therefore, when the sleeve is inserted in the case, be formed an annular chamber, n, extending from the bottom of the iiangej to the-point where the larger aperture terminates, the bottom of the chamber being the internallyprojecting flange or collar j'onthe case, which comes into contact with the sleeve. The case may, however, be bored through the diameter of the chamber and the sleeve formed with flanges on both ends, as shown in Fig. 2, if it be so desired.

In the flanges or collars jj are formed ducts d4, through which the oil enters the chamber n, it being forced in through the bottom duct by the gravity ofthe oil in the reservoir and through the top one by its own gravity from the cup ef. Through the sleeve H are formed inducts of such capacity that the oil cannot pass through them in much greater quantity than is required for perfect lubrication, and also of such capacity that any such slight excess' of oil which may so pass tothe spindle will be much less than its capacity to carry it out over the top of the bolster by capillary and centrifugal force. These inducts may have their capacity limited by having their diameter made very small, as shown by the induct on in Fig. 2, or by having their orifices covered with some material which retards the entrance ofthe oil, as shown at m in Fig. 1. Besides these inducts, additional ones," m2, placed near the bottom of the upper bearing of the spindle and above thelsurface ofthe oil in the chamber n, may be made, to which ductsthe oil is conveyed by the capillary attraction of the brous materialjr, placed in the chamber n, and by the draft of the spindle drawn n through them. These ducts being formed near the lower part of the bearing, the latter will be completely and perfectly oiled by the upward vcapillary force of the spindle and bolster without any expenditure ofthe power which drives the spindle, whilefat the same time the orifices being IOO above the level ofthe oil in the chamber n and supplied as above described, will have delivered to them so limited a quantity of oil that the requirements ofperfect lubrication demand nearly all that will be so furnished, and there will be but little to be carried up and discharged over the top of the bolster.

The capacity ofthe inducts m and m2, when used either together or separately, is so limited that the spindle will carry any oil which passes through them not needed for the lubricationof the step and bolster up out of the sleeve, so that the spindle will be surrounded by air from its bolster to its step in the space marked a.

Upon the outside of the case D is formed a thread, by which it is screwed into the chamber o, formed in the rail R for an oil-reservoir. From the cup c there are carried down ducts d2, which terminate below the thread formed upon the case, so that oil may flow from the cup c either through the ducts d4, already described, into the chamber n, or through the ducts d2, last described, into the oil-reservoir 0. The oil, therefore, which is carried up by the capillary and rotary action of the spindle and discharged over the top of the bolster will run back either into the reservoir or into the case containing the filtering material th rough its appropriate ducts d* d?.

Upon the `top of the case D is formed the lian ge d3, made concentric with the bolster h, and of a slightly greater circumference than the flange b upon the whirl. Upon the flange d3 a collar, s, is fitted, which has an inwardlyprojecting ange, t, upon its upper edge, which overlaps the ila-nge I) on the whirl.

When the spindle is in position and the collar passed down over it to its place and made fast upon the flange d3, either by a set-screw, bayonet-joint, or in any other equivalent manner, the spindle cannot be lifted from its step.

The reservoir o is made to connect with the adjacent reservoirs for adjacent spindles by means ofthe passage p, which is connected at a convenient place with an oil-cup, through which oil may be supplied to all the reservoirs, whether the spindles are at rest or in motion.

Then the spindle is in operative position and oil has been once supplied to it, as well as to the reservoir o, and the spindle put in operation, the first effect of the rotation of the saine is, by reason of its tapering form, to carry ont over the top of the sleeve all the oil contained therein between the step and the bolster, after which the spindle will be in contact with the bolster and step, and not in frictional contact with the sleeve or with a column of oil between the bolster and the step; and as no oil can obtain entrance to the step at the bottom of the sleeve, and the quantity which can pass through the inducts is very small, the spindle will rotate in air between its upper and lower bearing-points-a result not heretofore obtained in any reservoir oilin g spindle having its step and bolster connected.

As air is a much thinner fluid than oil, it is manifest that a great saving in power is made by bringing it in contact with the spindle instead of oil upon that part ot' it, and as the oil is supplied near the point through the induct m2, which is covered by the brous material in the chamber noutside the rotation of the spindle, and in such quantity that little or none from the inflow at this duct is ordinarily carried up and discharged over the top of the bolster, it is manifest that much less power is required to drive the spindle than when the oil must be elevated to the bolster andis continually passing over its top, only to run down and again make the circuit. Itis also evident from the arrangementof parts as shown thatno oil can be wasted by being thrown ofi' the spindle, and that it is difficult, if not entirely impossible, for dust or dirt to come in contact with the oil in use.

The duct m being arranged to discharge its oil into the space in the sleeve between the bolster and step, the oil will not come in contact with the spindle until, after flowing down the interior of the sleeve, it comes in contact with the spindle at the step, and the amount' supplied to the step will be so little in excess of the actual requirements for lubrication that there will be but little to be carried upward by the rotary action of the spindle. The spindle, therefore, will be perfectly oiled without being in frietional contact with' either metal or oil between the step and the bolster, and will not be compelled to sustain a column of oil reaching from its lower to its upper bearing to 1ubrieate the latter, while the oil which overflows the bolster is free to return again to the bearing surfaces without coming in contact with the air in the mill-room. It will also be observed that I have provided a method of keeping the spindle in place which is at once neat and perfect, while the part used to accomplish this purpose is entirely below the band, and, besides, being thus out of the way of the band, serves as an additional protection from dirt to the oil-cup of the spindle-case. It will also be observed that by this construction I am enabled to make my spindle smaller and lighter below its bolster-bearing without impairing its lubrication or strength, and that by so lightening it 1 am enabled to produce a spindle which will require less power when in operation.
