SPINDLE AND BEARING.
SPECIFICATION forming part of Letters Patent No. 601,846, dated April 5, 1898.
Application filed October 24, 1896. Renewed November 13, 1897. Serial No. 658,437. (No model.)
To all whom it may concern.-
Be it known that I, WALLACE I. STIMPsoN, of Milford, 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 and numerals on the drawings representing like parts.
This invention relates to that class of spinning-spindles wherein the spindle-step is made adjustable relatively to the bolster, into the tapering bore of which the tapering pintle of the spindle enters, the adj ustability securing a uniform fit between the pintle and the bolster in order to insure steadiness of rotation and equaldistribution of wear of the parts.
In this invention Ihave provided a simple,
and effective lock to prevent relative rotation of the bolster and step, the lock being easily released when the bolster and step are therein,having a tapering bore to fit the taper ing pintle S of the spindle S, the attaching nut B for the bolster-case, the packing P, and the oiling device for the spindle are and may be of usual construction.
The bolster I), provided with the usual fibrous packingP, is threaded at its lower end at b, Fig. 1, to engage the threaded stem or' shank o of the step c, rotation of the bolster relatively to the step regulating the fit of the pintle of the spindle in the bolster.
I have provided a simple lock between and to prevent relative rotation of the bolster and step, attached to one and adapted to detachably engage the other, and said lock is herein shown as a small and preferably flat springfinger 5, attached by a rivet 5 to a longitudinal notch in the step c, the free end of the I finger being adapted to enter one of a series of longitudinal grooves or depressions b on the exterior of the ,bolster.
The normal tension of the spring-finger s maintains it in engagement with the bolster and prevents rotation of the step relatively thereto, while adjustment can be readily effected by raising the free end of the spring from its retaining notch or groove and rotating the parts 5 and o to the desired extent, the finger slipping into anothernotch as soon as released.
To facilitate unlocking, the free end of the V spring-finger 8 may be slightly bent outwardly,
as at s, if desired.
Obviously it would be a mere reversal of parts and no departure from the spirit and scope of my invention to permanently attach the locking-finger s to the bolster and provide the step with a series of retaining grooves or notches b as in Fig.4. 1 A projection or lug b on the exterior of the bolster is adapted to enter agroove 10in the case B to prevent the bolster from turning in its ease.
Having fully described my invention, what I claim, and desire to secure by Letters Patout, is-
1. A bolster-case, a bolster held from rotation-therein and havinga tapering bore, a spindle having a tapering pintle to enter said bore, a step adjustably connected with the bolster by a screw-thread, and a spring loek-' ing-finger, on the step adapted to engage the bolster and prevent rotation of the step relatively thereto, said finger having its free end bent out to facilitate unlocking, substantially as described.
2. A bolster-case, a bolster held from rotation therein and having a series of longitudinal notches at its lower end, a spindle to enter the bolster with a tapering fit, a step adj ustably connected with the'bolster by a screwthread, and a yielding locking-finger secured to the step and adapted to enter one of the notches in the bolster, substantially as described.
name to this specification in the presence of two subscribing Witnesses.
