SPlNDLE-BEARING.
SPECIFICATION forming part of Letters Patent No. 605,703, dated June 14, 1898, Application filed May 22, 1897. Serial No. 637,707. (N0 model.)
To all whom it may concern:
Be it known that I, GEORGE O. DRAPER, of Hopedale, in the county of Worcester and State of Massachusetts, have invented an Improvement in Spindle-Bearings, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. 1 I
This invention is intended as an improvement upon the spindle -support shown in United States Patent No. 507,355, heretofore granted to me, and dated October 24, 1893. In that patent I show a bolster tapered internally to fit the taper -of the spindle, and said bolster is supported at its lower end by a spring; but in practice it has been found that the bolster so supported is apt to rise on or with relation to the spindle and fit the same too tightly. To obviate this difficulty, I have provided the upper end of the supportingcase with an adjustable threaded collar which when screwed into the said supporting-case may have its lower end adjusted to just the proper position to arrest the upper end of the bolster acted upon by the spring with relation to the step on which the lower end of the spindle rests that the fit between the tapered interior of thebolster and the tapered e'Xterior of the spindle will be just a proper running fit.
Figure l of the drawings represents a spindle with a bolster and step in section, the same embodying my invention; and Fig. 2 shows the threaded collar detached.
The spindle a, having a sleeve-whirl a, the bolster-rail b, the bolster therein secured to the rail by a suitable nut, as 6 the step c, and its spring 0 are and may be all substantially as in saidpatent.
The pintle or lower end a of the spindle is shown as tapering, and this tapered lower end is surrounded by a bolster d, which is bored tapering to fit the taper of the pintle, and the lower end of the said bolster, open for the passage through it of the lower end of the spindle to rest on the step, is acted upon by the springc, the said'spring pressing upwardly upon the bolster andcrowding it at all times against the tapering pintle of the spindle.
It is necessary to secure the best results in running a spindle of this class that the bolster should fit the taper of the spindle with vbolster acted upon by the spring. of this collar, therefore, and the provision gained.
a good running fit; but this fit between the bolster and the pintle of the spindle cannot be maintained properly by the spring alone ster a collar 6, it being threaded exteriorly. 'The lower end of this collar rests against the upper end of the bolster, and by rotating this collar its position may be changed vertically, thereby changing vertically the position of the By means made for its adjustment it is possible to insure exactly the fit between the tapered interior of the bolster and the tapered exterior of the pintle of the spindle, and great steadiness of operation and efficiency of the spindle is The said collar and spring also 00- act to adjustably regulate the freedom with which the bolster may move laterally, as the end friction must be overcome before such movement is possible.
Having fully described my invention, what -I claim, and desire to secure by Letters Patent, is
A bolster-case provided at its upper end with ascrew-thread; a bolster placed in said case and provided with a tapering bore; a spindle having a tapered pintle to enter the tapering bore of said bolster; a step for the lower end of said spindle, and a spring interposed between said step and the open lower end of said bolster, combined with an adj ustable collar engaging the screw-thread at the upper end of said bolster-case, said collar cooperating with the said bolster to determine its ascent in the bolster-case under the action of said spring, and thereby regulate the fit between the tapered surface of the bolster and the tapered pintle of the spindle substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
GEORGE O. DRAPER.
