UNITED STATES PATENT OEEIcE.
WILLIAM T. CARROLL, OF VOROESTER, ASSIGNOR TO GEORGE DRAPER 85 SONS, OF I-IOPEDALE, MASSACHUSETTS.
SPINDLE-BOLSTER.
SPECIFICATION forming part of Letters Patent No. 327,135, dated September 29, 1885.
Application filed April 27, 1885.
T0 @ZZ whom it may concern:
Be it known that I, WILLIAM T. CARROLL, of the city and county of Worcester, State of Massachusetts, have invented an Improvement in Spindle-Holsters, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
In that class of spindle and bearings where` in the bolster and foot-step are both located below or one within the whirl, the bolster has depended for its main lateral support upon a metal sleeve erected upon or forming part of a hub or base held in the step-rail and chanbered to contain oil and constitute an oilwel To prevent the injurious gyration of spindles when running at high speed, the bolster between its external surface and the interior of the said sleeve has been surrounded by an elastic or yielding jacket or packing usually composed of brous material, but sometimes of oil alone, such jacket or packing permitting the bolster to yield freely in any direction laterally when the spindle is iinding its true center of rotation.
In my experiments, to avoid the employment of aloose bolster, and consequently of' special means to restrain its rotation with the spindle, and also to obviate the use of an elastic or yielding packing of the class referred to, which has frequently to be renewed, and also tolighten the weight of metal in spinning, I have discovered that a bolster supported externally above the rail and at a point within a sleeve-whirl by a non-metallic bolsterholder does not need to have the bolster inclosed or surrounded by an elastic packing,
(No model.)
The spindle A, with its attached sleevetion.
The hub or base C, inserted in a socket of 5 5 the rail I3, and there confined, has a head or enlarged part,wl1ich forms part of the oil-Well and receives a foot-step, a.
Extended above the hub or base C and connected therewith is a non metallic bolster- 6o holder, d, made as a tube, in the upper end of which is fitted the metal bolster e, in which the pintle of the spindle enters, the lower end thereof resting upon the foot-step a, the nonmetallic bolster-holder entering the sleevewhirl, and being extended therein preferably up to or above theline of the band-pull on the whirl. Among the non-metallic substances which I have found to answer well for the bolster-holder are wood,celluloid,and vulcanized 7o ber. Instead of these materials I may use any other well-known non-metallic substances having substantially the same degree of elasticity and possessing the quality o1' not being injuriously affected by oil.
I have embodied my invention practically in several different forms- 21s, for instance, the hub or base C shown in Fig. l maybe a nonmetallie substance-such as wood or vulcan` ized fiberMand if the non-metallic substance 8o employed is the same as that of which the bolster-holder is composed, then the said bolster-holder and hub or base may be made integral, as in Figs. 2 and 3.
rI he lower end of the hub or base may be screw-threaded and be held in the rail by the usual nut,g, or ne acted upon directly by a set-e` screw, f, asin Fig. 2; or, if desired, the said end may be placed in a sleeve, 7L, slotted at one side from end to end, as at the left of Fig. 9o 3, the latter serving asa clamp,whieh may be contracted by means of a set-serew,f.
I desire it to be understood that the hub or base C shown in Fig. 1 may be of metal.
rlhe non-metallic bolster-holder d, extended above the hub or base, possesses an amount of elasticity sufficient to yield to the requirements of a rapidly-rotating spindle, thus deadening its vibration due to an unbalanced load.
The non-metallic bolster-holder shown in roo Fig. l is made as a tube having a close fit at its lower end,bctwcen the hub or base and the foot-step; but in Figs. 2 and 3 the said holder d is integral with the hub or base.
In the drawings, the bolster e is a lit in the non-metallic bolsterholder,and the lower end of the bolster rests on the foot-step; but this is not a necessity, for the weight of the bolster may be supported by the colla-r at its upper end resting,` on the top of the bolster-holder.
I am aware that abolsterhas been supported in a yielding manner by indiztrubber placed in a step, as in United States Patent No. 82,049, September 8, 1868, for a centrifugal machine, and I do not claim such asnpport. In my invention the bolster-holder-the nonmetztllic member or element-is extended above the hub or base and in its upper part holds the bolster.
