SPINDLE AND BEARING THEREFOR.

SPECIFICATION forming part of Letters Patent No. 269,438, dated December 19, 1832. Application filed May 13, 1882. (No model.) i

To all whom it may concer-n v Be it known that we, GEORGE B. MoGEAoK- EN and SAMUEL HAMEn, of Wi11imantic,in the county of Windham and State of Connecticut, have invented a new and useful Improvement in Spindles and Bearings Therefor, of which the following is a full, clear, and exact description.

Our invention relates to that class of spindies in which the bobbin is held steady at the top by a short spindle and turned by a whirl placed on a central stud and it consists in the construction, arrangement, and combination of the parts of the spindle, whereby the bobbin is made to run easy, steady, and true, the bearings properly oiled without the oil retarding the motion of the spindle or soiling the bobbin,

Vthe oil used over and over again, and the supply of oil in the reservoir not agitated by the motion of the spindle, and also whereby the p parts ofthe spindle may be easily taken apart for cleaning and the`wearing parts replaced with ease and small expense, all as hereinafter described.

Reference is to be had to the accompanying drawings, forming part of this specification, in

which similar letters of reference indicate corresponding parts in all the figures.

Figure l is an elevation of our new and improved spindle and a portion of the rail with the bobbin removed. Fig. 2 is an elevation of the bobbin. Fig. 3 is a central vertical section, part in elevation, ot'our invention. Fig.

4 is an elevation of the bushing in which the.

short spindle B is held. Fig. 5 is an inverted plan ot' the lower end ofthe said bushing, showing the perforations therein. Fig. 6 is an elevation ot' the bushing D, forming the upper bearing of the sleeve E. Fig. 7 is a cross-sectional view'of the bushing D, showing the grooves therein. Fig. 8 is a partial sectional elevation of said sleeve E; and Fig. 9 is an ele` vation of the tube placed'in the lower oil-cup,

` F, for preventing agitation ofthe oil in the cup from the rapid revolution of the downward extension ofthe whirl G of the spindle.

A represents the iron base of the spindle, which is cast so as to form the oil-reservoi r F, in which the oil for lubricating the lower bearings of the spindle is placed. rlhe bottom of this reservoir is formed with the annular depression or channel f." for the retention of any sediment or gritty deposits that may be in the oil, and the base A is adapted to be secured to the rail Hin the ordinary manner.

Firlnly screwed into the base A is the stud C, which is made small enough to be slightly elastic, but not so elastic that it will be liable to be deflected by the pull ot' the band which turns whirl G. The object of making this stud slender is to so condition the spindle that it will adjust itself to any unequal distribution oftheload, the same as a packed bolster will do.

The sleeve E is placed upon the stud C and turns with the whirl Gr, and surrounding the sleeve and the stud is the short tube J, which ervoir. The lower edge of the tube J is by preference formed with the notches jj, through which the oil passes from the main body ofthe reservoir to and in cont-act with the sleeve and stud. lower end the bushing A', which tits and turns upon the stud C and forms the lower bearing for the sleeve, and formed upon or secured to the outside ofthe sleeve are the collars b and b', the latter being' at the upper end of the sleeve, as shown. AThese collars tit snugly the interior -of the hollow and slightly-tapered upward extension d of the whirl Gr, so that the sleeve E is made fast to the whirl, and is thus caused to turn with it. The lower end of the bushing A ot' the sleeve E rests upon the bottom-ofthe oil-reservoir F, and is beveled od', as shown at i t', for reducingthe friction and to facilitate the inflow of oil from the reservoir to its bearings upon the stud C. The bushing D is titted snugly into the sleeve E a suitable distance above the bushing A', and vforms the upper bearing for the sleeve E. '.lhis bushing D is formed with the oil passages or gutters e e upon its outside, as shown clearly in Fig.7. When the spindle is in use the rapid revolution of the sleeve E will cause the oil to be drawn up between the stud C and the inner Wall of the sleeve from the bushing A', and

Tile sleeve E has secured init at its TOC to Work between the stud C and the inner the sleeve E above the bushing D, and above the collarl b', where quite a quantity will be maintained, which w.ill always insure the thorough lubrication of the bearing 'between the bushing D and the stud C.

Above the bushing D the sleeve Eis by preference formed upon the inside, with the spiral groove or thread c, which will tend to carry or force the oil back through the gutters e c ot' the' bushing D and down to the reservoir F, so that .the oil will be used over and over again.

The stud G may, if found necessary, be formed with a spiral groove or thread for assisting the oil to rise from the reservoir for lubricating the bushing D. By thisl means it will be seen that it will be impossible for the oil to clog up the oil-passa ges, so as to materially interfere with perfect lubrication, as the gutters in the bushing D, in connection with the spiral grooves in the sleeve E, furnish several sources of supply, allot' which are not likely to get clogged at the same time. The upper end oi' the stud C isheaded, as shown atti", which is `centrally socketed, as shown at f' in Fig. 3, and inthis socket the lower end of the short spindle B takes its bearing.

To the upper end of the stud G is secured the shellK, the lower end of which forms a stop for the upper end of the sleeve E to strike against when dofng. In the upper end of the shell K is screwed the bushing L, which is formed with the downward extension L', which incloses the greater part ot the short spindle B, as shown in Fig. 3. ,At the lower end of the downward extension Ll ofthe bushingisformed the collar l, extending across the space o, between the shell K and the outside of the extension L', which forms an oil-reservoir for holding the supply of oil for lubricating the upper bearings of the spindle, and this reservoir o communicates with the lower oil-reservoir p through the perforations g g, made through the collar l of the extension L'.

The reservoirs 0 and p are lilled with oil through the passage h and side passages, t" i', made in the upper end of the short spindle B, and the vertical passages e' e', made in'the bushingL. (Shownin Fig. 3.) The downward extension L' forms a tube, through which' the oil is drawn by the .rapid revolution of the spindle from thelowcr oil-reservoirp up to the bearingof the short spindle B in the bushing L. This raising of the oilmay be aided, if desired,by forming a spiral groove or thread in the inside oi' the downward extension L. The collar l fits the shell K and prevents the oil in the reservoir o from being agitated by the revolution of the spindle. Reservoirs o and p are practically one, both being kept full of oil, the collar Zserving to check the violent motion ot' the oil, which might otherwise be driven up away from the step j' by the centrifugal force of collar m on the spindle B. The oil,at`ter passing up th`e spindle B and sleeve L' for oiling the spindle, passes into the passages e e" in the bushing back to the reservoirs o and p, to be used over again. The hole t in the upper end of the bushing L serves for a vent, and as a place to insert a tool to serve as a lever or wrench for unscrewing the bushing. t' is a similar hole or passage through the lower end ot' the shell K and through the stud C for receiving a tool for unscrewing the stud from the casting A.

The upward extension d ofthe whirl G is, as above mentioned, made slightly tapering or conical, so that the bobbin N will t tightly upon it. The upper end of the bobbin ts upon the upper end of the short spindle B, by which it is steadied, and the short spindle revolves with the bobbin. By this means it will be seen that the weight of metal that revolves with the bobbin is reduced to the minimum, thus requiring less power to revolve the spindie, and obvating, to a great extent, the vibration which the spindle would otherwise have. The passage h through the short spindle B, while serving for an oil-duct, also materially lightens the spindle without impairing its strength.

Upon the lower end of the short spindle is driven the collar m, which prevents the spindle from being raised out of its step in the head f when dofiug. In filling, through the passage h of the short spindle, the reservoirs 0 and p with oil, shouldv the oil happen to overow through the holes t, it will pass down the outside of the shell K, into the upper end of the upward extension d of the whirl, and from thence, through the gutters e in the bushing D, down inside of thc sleeve E into the lower reservoir F, and not in any manner soil the bobbin.

By this construction and method of oiling it will be seen that the oiling is positive and sure, that the reservoirs will hold enough oil to run a long time without refilling, and that the reservoirs are so arranged that the motion of the spindle will not be retarded by the supply of the oil in the reservoir, nor the supply agitated by the motion of the spindle. 1t will also be seen that, the bobbin being held only at top and bottom, and the weight of metal revolving therewith being.very small, the spindle will run very light, steady, and true; that the size of the bearings does not exceed the usual size ot the best spindles; that the side pull ot' the baud is done away with. and that in case of wear the bushings A', D, and L can be readily and easily replaced at a small cost and very little delay, and the spindle can also be easily taken apart for cleaning and repairs.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
