SPINDLE AND BEARING.
SPECIFICATION forming part of Letters Patent No. 609,759, dated August 23, 1898.
' Application filed December 18, 1897. Serial No. 662,366. (No model.)
To all whom t may concern,.-
Be it known that I, GEORGE O. DRAPER, of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Spindles and Bearings, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention relates to that class of spin' ning-spindles wherein the tapering pintle of the spindle enters a correspondingly-tapered bolster located in the bolster-case and it has for its object the production'of means for securing the propert of the pintle in the bolster in a simple and eiiicient manner, the bolster being adjusted vertically until the proper fit is attained. p
In my present invention the bolster is sustained within the bolster-case by a support on and relative to which the bolster is vertically adjustable, the bolster having a frictional engagement with and being adapted to slide longitudinally in the support.
Figure l is a vertical section of a spindlebearing with one embodiment of my invention applied thereto. Fig. 2 is a perspective view of the bolster-support. Figs. 3 and 4 are sectional and perspective views of a modified form of support; and Fig. 5 is yet another modification of myinvention, to be described.`
The spindle A, having a tapering lower end or pintle and provided with a sleeve-whirl A2, the bolster-case B, having a threaded shank B2, and the nut B3, to clamp the case to the rail O, may be and are of usual or well` known construction.
A step or end bearing D for the spindle is shown in Fig. l as resting on the bottom of the closed lower end of the bolster-case and lling the same.
The bolster BX may be of any suitable construction, and it is shown as sustained by a support F, shown as a sleeve split longitudinally at f, Fig. 2, and resting on the step D, the lower end of the bolster being telescopically connected with and held by frictiony in the support. In order to adjust the bolster,
it is pushed more or less into the support and held frictionally thereby in adjusted vertical position.
I have omitted any packing for the bolster, and the same `may be of any suitable or wellknown character.
In Figs. 3 and A l have shown the support EX as closed at its lower end and slotted longitudinally at f to attain the desired expansibility, the spindle-step D inthis instance resting on the bottom of the support, the adjustment and support of the bolster being effected as before.
, Still another modification is shown in Fig. 5, the cup-like support F being made nonexpansible and adapted to receive the lower end of the bolster B5, the latter being reduced in thickness at b and slotted, as at b5, to make a tight frictional fit in the support. The reduced end of the bolster does not touch the pintle of the spindle to obviate any pinching of the latter in adjusting the bolster.
In any case the adjustment of the bolster to secure the proper iit of the pintle therein is readily and quickly eected, and the construction is simple, cheap, and durable.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-
l. A bolster-case, a bolster, a concentric support telescopically connected with and frictionally engaging the bolster and on which support said bolster is vertically adjustable, and a spindle -step unconnected withV the bolster. Y
2. The combination with a bolsteigof a split, sleeve-like support in frictional engagement with the lower end of and to adjustably sustain the bolster at any desired height relative to said support.
3. A spindle having a tapered bearing portion, a bolster therefor, a split bolster-support lengaging with a sliding fit the lower end of the bolster, to adjustably support the bolster, and a spindle-step below the engaging portion of the bolster and its support.
4. A spindle having a tapered bearing por-V GEORGE O. DRAPER.
