RUDOLPH H. APELT, OF ROXBURY, MASSACHUSETTS.
BALL-BE Application filed February 25,
1'0 all w/mm it may concern.-
Be it known that I, RUDOLPH H. APELT, a citizen of the United States, residing at Roxbury, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Ball-Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to ball bearings adapted for use in connection with the trolleysheaves of electric railroads; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a vertical longitudinal section through a trolley-sheave provided with a ball-bearing according to this invention. Fig. 2 is a side view of the trolleysheave, showing the ball-bearing in cross-section.
A is a trolley-sheave adapted to be pressed against the line-wire of an electric railroad.
B is an outer bush, which is secured in the central portion of the trolley-sheave and provided with ball-races b and 0 at its end portions. An oil-hole Z) is also preferably provided in this bush.
D and E are two inner sleeves or bushes arranged inside the outer bush B. The sleeve D has a ball-race (Z arranged opposite the ballraoe b, and the sleeve E has a ball-race 0 arranged opposite the said ball -race 0. The sleeves D and E have flanges F and G at their opposite ends, respectively, and these flanges or disks close the ends of the outer bush B. One of the said sleeves has an externally-screwthreaded projection It, which engages with an internally-screw-threaded recess 2' in the other sleeve, so that by revolving one of the sleeves relative to the other the positions of the ballraces can be adjusted. Each said sleeve has a central hole provided with a series of longitudinal grooves, serrations, or corrugations y'. J is a supporting-shaft. This shaft is secured Specification of Letters Patent.

in the forked head K of the trolley-pole in any approved manner. The shaft J is provided with projections K', which engage with the serrations of the two said sleeves and prevent one sleeve from being revolved with respect to the other said sleeve.
In order to form the shaft J with the requisite projections, it may be made square in cross-section,as shown,or it may be triangular, hexagonal, or any other cross-section which will enable it to engage with the serrations of the sleeves.
H indicates the antifrietion-balls, which are arranged between the opposed ball-races. The ball-races can be adjusted with great nieety as they become worn by removing the shaft J and revolving one sleeve with respect to the other.
\Vhat I claim is 1. In a ball-bcaring, the combination, with an outer bush provided with ball-races at its end portions, of two inner sleeves provided with ball-races at their outer end portions and screw-threaded portions at their adjacent ends which engage with each other, said sleeves having also central holes provided with serrations, balls arranged between the opposed ballraces of the said sleeves and the said bush, and a shaft which engages with the said serrated holes of the sleeves.
2. In a ball-bearing, the combination, with a revoluble bush provided with ball-races at its end portions, of two sleeves provided with ball-races and screw-threaded portions which couple their adjacent ends, said sleeves having also central holes provided with serrations, balls arranged between the said opposed ballraces, and a stationary supporting-shaft which engages with the serrations of the said holes.
In testimony whereof I have affixed my signature in the presence of two witnesses.
RUDOLPH H. APELT.
