ANTIFREEZING-HYDRANT.

Specification of Letters Patent.

Patented June 25, 1918.

Application led December 20, 1917. Serial No. 208,101.

To all `whom zt may concern Be it known that I, MICHEL STANIsLAUs YAssUKovircH, a subject of Russia, residin at New York, in the county of New Yorc and State of New York, have invented certain new and useful Improvements in Antifreezing-Hydrants; 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.

The present invention relates to improvements in anti-freezing hydrants, in which provision is made for draining the water from the water delivery stock when the valve which controls the passage of the water from the water service pipe, or main, to said stock is closed.

The present invention aims primarily to drain ofi' the water at a low point in the system by a simple and automatically operating device, and to incidentally remove to a separate stock provided for the purpose, the valve-actuating mechanism which was heretofore located in the water delivery stock where it interfered with the free passage of the water, and caused a material reduction in the available pressure at the surface.

In the accompanying drawings forming a part of this application` and in which similar reference symbols indicate corresponding parts in the several views:

Figure 1 is a vertical sectional view of'V an anti-freezing hydrant with associated parts partly shown in elevation, and constructed in accordance with my present invention.

Fig. 2 is an enlarged fragmentary sec-` tional view of the water valve and draining device.

Fig. 3 is a vertical sectional view with parts shown in elevation, showing the draining device applied to a different type of valve and illustrating a different form of plug.

Fig. 4 is an enlarged fragmentary sectional view of the valve and draining device shown in Fig. 3; and

Fig. 5 is an enlarged plan view of the plate for holding the drain pipe.

Referring more particularly to the drawings, 1 designates the usual water delivery stock which may be connected to the upstanding plug 2, as appears in Fig. 1, or

to the sunken plug 3, shown in Fig. 3; and 4 represents the connection or elbow usually employed to place the stock 1 in communication with the service or water supply main 5.

In accordance with the present invention the water valve 6 and its operating mechanism 7 are removed from the water delivery stock 1, and are placed respectively 1n a valve casing 8 included at a convenient point in the service or main 5, and in a separat-c stock 9 near to or remote from the water delivery stock 1, as conditions render advantageous. Access may be had to the valve operating mechanism 7 through the cover plate 10 at the surface.

The effect of the new locations given the water valve 6 and its operating mechanism 7 is to leave the stock 1 free from obstacles to the passage of the water in great volume and at high pressure, and furthermore allows of lacing the water valve G at a lower location than was heretofore possible; which allows the water from the stock 1 and connection or elbow 4, to drain completely therefrom through an opening 11 which I provide for this purpose in the lower part of the water valve 6. When the valve 6 is finally closed this opening 11 will remain just above the lower part 12 of the valve seat, and will afford free egress to all of the water remaining in the stock 1- and elbow 4.

Figs. 1 and 2 show the application of the invention to a hollow cone valve 6; while in Figs. 3 and 4 the invention is shown applied to a double-disk expanding gate valve 13.

Referring now first to Figs. 1 and 2, the draining device is represented in the form of a conduit or pipe 14, which is attached to and moves with the valve 6, passing through a stuffing box 15 provided at the bottom of a depression 16 in the valve calsing 8. One means of connecting the drain pipe 14 with the valve 6 consists in boring and threading the lower end of said valve, as is illustrated at 17 in Fig. 2, and in placing therein two spaced and perforated disks 18 and 19 which loosely imprison therebetween a third disk 20 fixed in any desired manner to the upper end of drain pipe 14.

A plug 21 is employed to close the lower end of the pipe 14, and a perforation or eduction port 22 is made therein at a suitabi@ elevations a.. ma; t.,

trough 23 whichA Hconveysit-away fromvthe valve casing. v Referring in pipe 14 vis held'A to movel with the lvalve 13 by' a plate24, which is provided,

gated 'slots 25 and'26 at itsvends.; .Screws 27` and 28 engage throughr said slots k25` and 26 and are threaded into the disks-.of y l waterto thel- 'sur the valvel. This lconstructionallows .the disks of the valve 13 to lexpand vand con.

which the valve may be opened to the rei with, the' perforation or eduction tract in the'usualmanner, and atthe .sanney time provides a convenient .means for car-,-

rying the drain 'pipe 14.

The operation of the invention the same in either formof the constructionsde-k. scribed, and may be briefly described as;

follows The water valve is normally closed, as

shown in Fig. 3, in which position it entirely cuts oli' the supply of water to the stockl 1 and plug above. When waterv is desired the cover 1Q of the stock 9 is irst removed and a proper implement engaged with vthe valve operating mechanism 7, by

quired degree. As the water valve is raised it draws/the drain pipe 14 upwardly thereort 22 being finally carried within the stu ng box 1.5, where it will be masked and the discharge of the watertherethrough prevented.-

However, when the `water valve is opened to a small degree only, for instance as shown in Fig. 1, the perforation' -22 will remain unmasked andy will' permit the escape of a' small quantity of water that mayl seek itsl way through the opening 11 in. said valve. This amount of water willrbe'vsm'all, but it will exert 'a cleansin n terior of the valve and rain vpipe 14.

When the supply of wateris discontinued by the closing of the valve v6,-all fof. thek waste water in the stock 1' and elbow 4 may pass through the drain opening 11` into the hollow interior of the valve body and .thence may flow directly 'downward Vthrough thev pipe 14 and out through the eduction port 22.-?.

It will be apparentv to all those skilled V`in, the art that althoughI have described the invention'in connection with gate valves forv hydrants, the improved device is ,applicablev to ,other valves and .other systems.

It is obvious vthat the details of construction vand arrangement of` parts may be varied without departing from the spirit of my invention, ai'idtherefore Iv do not .wish

tobe limited to such features except'as may f be required by the claims. j v 'l d Iclaim; l l
