JESSIE PIERPOINT, OF YONKERS, NEW YORK.

BALL-BEARING RAIL.

Application led October 8, 1921.

To all 'whom t may concern Be it known that I, Jnssin PrnnroiN'r, a citizen of the United States, residing at Yonkers, in the county of lllestcliester, State of New York, have invented certain new and useful Improvements in Ball-Bearing Rails; 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.

rThis invention relates to new and useful improvements in railway appliances and particularly to attachments for railway rails.

One object of the invention is to provide an antifriction means for the rails of a l curve againstl which the wheels of a train are adapted to bear to relieve the wheels and rails of wear and strain, the attachment being so constructed and arranged that it may be readily applied to the rails now in use without any modifications to the rails, or displacements thereof.

Another object is tov provide a device of this character which is simple in construction, is readily applicable to the ordinary railway curves, and which can be manufactured at a comparatively low cost.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

1n the drawing:

Figure 1 is a top plan view of a railway curve showing the invention applied thereto.

Figure 2 is a side elevation of the same.

Figure 3 is an enlarged vertical transverse sectional view on the line 8 3 of Figure 1. Referring particularly to the accompanying drawing, there are shown the inner and outer rails 10 and 11, of the curve of a railway, in connection with which the present invention is adapted for use. Each of the raiis includes the tread 12, web 13, and base flanges 14. The rails 10 and 11 are secured to the usual ties 15.

Disposed on the end portions of the ties, outwardly of the outer rail 10, is a curved rail 16, including a base flange 17, a vertical web 18, and an upper outwardly extending portion 19. The lower end of the web has formed thereon thev downwardly and in- Speccaton of Letters Patent.

Serial No. 506,335.

wardly extending lugs 20 which engage beneath the base of the rail 10, while the base of the rail 16 rests on the upper faces of the tie ends. The web 18, of the rail 16 is disposed in close proximity to the web of the rail 10, as clearly seen in the section Figure 3, with the upper face thereof disposed beneath the tread of the rail 10. The inner portion of the member 19 is formed with a longitudinally extendin@r groove or race 21 in which are located t e series of bearing balls 2Q, the groove and balls being located above the tread face of the rail 1() to be engaged bythe side face of the car wheel 23, as the car rounds the curve. Between the member 19 and the base 17, are formed the bracing webs 27 which support the member 19 against the outward and downward' pressure of the wheels against the balls and the member 19. The rail 16 is secured to the ties by means of the spikes 25, which extend through the entire length of the curved portion of the rail 10. The

upper and lower walls of the groove or race 21 extend inwardly beyond the centers of the balls 22 whereby the balls areI secured within the groove, while being permitted to rotate freely therein, as the wheel engages therewith.

The peculiar construction and arrange ment of the rail 16, with respect to the rail 10 and the ties 15, effectively prevent movement of the rail 16 in any direction, while rendering it unnecessary to modify the construction of the rail 10.'

1V hat is claimed is:

An attachment for a railway curve comprising a curved rail having a base flange formed with downwardly inclined lugs, a vertical web, and a longitudinally grooved upper portion, and bearing balls disposed in the grooved portion, the said grooved portion being formed to lie above the tread portion of a railway rail and to have its lower portion underlie the said tread portion, with bracing webs extending between the base flange and the upper grooved portion.

In testimony whereof, I aix my signature, in the presence of two witnesses.

JESSIE PIERPOINT.
