BALL BEARING.

SPECIFICATION forming part of Letters Patent No. 696,777, dated April 1, 1902.

Application filed January 22, 1901. Serial No. 44,288. (No model.)

T0 on whom it may concern:

Be it known thatI, BALDWIN D. WARD, a citizen of the United States, residing at Millport, in the county of Chemung and State of New York,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 appertaius to make and use the same.

This invention relates to ball-bearings; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is alongitudinal section through the bearing. Fig. 2 is a cross-section through the bearing.

A is a shaft, and B is a sleeve secured on the shaft by a set-screw a. When the setscrew is slack, the sleeve can he slid longitudinally. The end portions of the sleeve are provided with ball-races b, and O are balls which run in the said races.

D is a cylindrical casing arranged concentric with the shaft A and forming an oilchamber cl around it. The casing D is provided with a base-plate d for securing it in position.

E represents cylinders provided with screwthreaded portions 6 at one end and plain cylindrical guide portions e at the other'end of smaller diameter than the portions 6. The portions 6 engage freely with the screwthreaded portions in the ends of the casin g D, and the guide portions e slide and revolve oil-tight in the oil-chamber of the cylindrical casing, between the screw-threaded portions at its ends. The cylinders E have internal inclined surfaces for bearing against the balls 0. The position of each cylinder is adjusted by revolving it, and it is then locked by a set-screw f, which engages with the casing and bears against its plain portion e. The

parts 6 keep the chamber d oil-tight and permit the cylinders to be revolved to adjust them without the exercise of great force. In

a shaft-bearing the screw-threaded portions c cannot be made oil-tight unless they are the plug G. Oil is inserted in the casing by removing the screw g, and g is a hole in the lower part of the casing provided with a plug or other means for closing it. The waste oil is let out of the hole 9 when the said plug is removed.

\Vhat I claim is- In a shaft-bearing, the combination, with a cylindrical casing having internally-screwthreaded end portions, an oil-chamber at its middle part, and a base-flange upon one side; of adjustable cylinders having screw-threaded portions at one end which engage freely with the screw-threaded portions of the cas ing, plain cylindrical guide portions at the other end which work oil-tight in the said oilchamber of the casing, and internal inclined bearing-surfaces, locking devices for securing the said cylinders in the casing, a shaft provided with a sleeve having ball-races at its end portions and arranged in the oil-chamber of the casing between the inclined bearing-surfaces, and balls arranged between the said inclined bearing-surfaces and ball-races, substantially asset forth.

In testimony whereof I affix my signature in presence of two witnesses.

BALD'WIN D. \VARD.
