able others skilled in the art to which it ap-v pertains to make and use the same. This invention relates to improvements in ball flush valves, andhas for one of its objccts the provision of a device of this char- 1 acter which can be'readily reversed upon the valve stem when one portion thereof has become worn.

Another object, of 'this invention isthe provision of aper'forated tube having means at each end for securing it in the ball and either of said means adapted to have the valve stem secured thereto, While the unused means will permit air to enter the tube and thence into the ball.

A further object of this invention is the provision of a ball fiushva'lve of the above stated character, which will be simple, durable and ellicient, and which may be manufactured and sold at a comparatively low cost.

l Vith these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as Will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference will be had to the following description and accompanying drawing, in which:

Figure l is a side elevation of a ball flush valve constructed'in accordance with my invention,

Fig. 2 is a vertical sectional view of the same,

Fig. 3 is an enlarged fragmentary vertical sectional view, illustrating the modified manner of securing the tube in the collars.

Referring in detail to the drawing, the numeral 1 indicates as an entirety a ball flush valve consisting of a spherical body 2 of hollow formation, preferably constructed Patented Dec. 3, 1918.

The collars 5 are provided With bores 7, the outer ends of which are internally screw threaded for connection with the screw threaded end of a valve stem 9 of the ordinary construction. a tube l0, hav- 111g openings 11, is shrunk in the inner ends of the bores 7 before the collars 5 are inserted in the'enlarged portions 4, so that when the body 2 is formed, the tube '10 extends centrally therethrough, so that air may enter the interior of the body from the bottom thereof. Instead of shrinking the tube in the collars, the tube V for cooperation with screw threads, as shown in Fig. 3, if desired.

From the foregoing description, taken in connection with the accompanying drawing, it will be noted that th applied to either of the collars, so that the body can be reversed when one portion thereof becomes worn from use on a valve seat.
