HERBERT H..HAM, OF BOSTON, MASSACHUSETTS.
BALL-BEARING.
SPECIFICATION forming part of Letters Patent No. 548340, dated October 22, 1895.
Application filedApril 19, 1895. $eria1 No. 546,292. (No model.)
To aZZ whom it may concern:
Be it known that I, HERBERT H. HAM, of Boston, in the county of Suifolk and State of Massachusetts, have invented certain new and useful Improvements in Ball-Bearings described in the specification, clearly illustrated in the drawings, and particularly pointed out in the claim.
Reference is to be had to the accompanying sheet of drawings, forming a part of this specification, in which like characters indicate like parts wherever they occur,
In the drawings, Figure 1 isa vertical sectional view of a spindle constructed in accordance with my invention. Fig. 2 is a similar view showing a modified form of my invention. Fig. 3 is a cross-section on the line 3 3 of Fig. 2, looking in the direction of the arrow.
As the bolster-rail and bolster-case form no part of my invention, I have not illustrated them in the drawings, but only the bolster itself, the whirl, and the spindle.
It is the main object of my invention to reduce the friction between the whirl, by which the spindle is driven and carried, and the bolster, which serves as a support for the spindle and whirl. To this end I form two 'iall-bearing surfaces in the whirl and complemental ballbearing surfaces upon the bolster and a detachable cap or plate connected to one end of the bolster, the whirl being maintained upon the bolster and maintained in its proper position by said cap or plate. By providing the bolster and whirl with two ball-bearings the parts are steadied. Furthermore, by means of this construction and arrangement the power required for running a series of spindles is greatly diminishes The bolster a is provided with the aperture to. in which is mounted the spindle with the usual screw-threads ed, by which it or is provided at its lower part may be united with the bolster-case. (Not shown.) The spindle is connected to and driven by the whirl b by means of the sleeve (1, fast upon the spindle, the sleeve (1 resting upon the whirl when in position and being provided with slots f, in which pins 5 0n the whirl project when the parts are assembled, any movement of the whirl thus being communicated to the spindle. Near its upper portion the bolster is formed with the flange d provided with the groove a near its periphery. An inclined bearing a connects this flange with the main part of the bolster and is suitably formed to serve as a part of one of two ball-bearings. The bolster terminates in a screw-threaded portion a".
The whirl b is provided on itsinterior with suitable grooves or depressions b, constructed to form each a part of the two ball-bearings, the said grooves being separated by a flange 5 as shown, in order to separate the two,
bearings and maintain the two sets of balls in their proper position. In these grooves 12' are arranged balls 19 that bear against the whirl and also the bearing a of the bolster, and a similar bearing cl, formed on the plate 61 screw-threaded, as at 61 to engage the screw-threads a From the foregoing it will be seen that there are two sets of ball-bearings, in each of which is arranged aset of balls separated by a flange b In assembling the parts the balls are placed in position, as shown, and the plate (1 arranged upon the bolster to retain the whirl in place and form a part of the upper hearing, as shown.
Instead of the construction shown in Fig. I, I may form the bolster in two parts x m. By this means the ball-bearin g Whirl and part ac of the bolster can be sold as separate articles and manipulated without disturbing the balls.
I claim- In combination, a bolster comprising a flange and a screw-thread portion a, said ange being formed with a ball bearing part o. surface, 03 a whirl mounted upon said bolster, and formed with two interior ball bearing depressions b, separated by a flange,

for the purpose set forth. A. D. HARRISON,
In testimony whereof I have signed my ROLLIN ABELL.
