WATER CUT-OFF.

Specication of Letters Patent.

Patented July 15, 1913.

Application filed May 7, 191.2. Serial No. 695,702.

To all 'whom t may concern Be it known that I, WILLIAM H. DANIEL, citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful lm rovements in Water Cut-0tfs, of which the ollowing is a specification.

This invention relates to cut-oit devices for automatically cutting oft' the flow of water when the temperature decreases to the freezing point and thus preventing the freezing of water in the supply pipes, and has for one of its objects to provide a device of this character of improved construction and increased eiiiciency and utility.

Another object of the invention is to pro vide a simply constructed device which may be applied without material structural changes to water systems of various kinds, and which will not interfere with the iiow of the water under no-rmal conditions, but which will automatically cut otf the water, and likewise provide for the drainage of the water which remains Ain the supply pipes in event of the temperature falling below the freezing point.

With these and other objects in view, the invention consists in certain novel features of construction as hereafter shown and described, and then specifically pointed out in the claims.

The improved apparatus may be applied to water conduct-ors of various forms and sizes, but is designed more particularly for use in connection with the ordinary water supply of residences, but it will be understood that the improved apparatus may be employed without material structural change to water supply pipes of any character, and it is not desired therefore to limit the invention in any manner in this respect.

For the purpose of illustration the improved device is shown applied to an ordinary water supply for a residence, and includes a conventional sink spigot.

In the drawings employed for illustrating the preferable embodiment of the invention: Figure l is a sectional elevation of the improved device in operative position with the parts arranged to permit water to iow therethrough; Fig. 2 is an enlarged sectional detail of the cut-oif valve; Fig. 3 is a plan view of valve as shown in Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The water supply pipe is represented at l0, and a conventional sink spigot at 11. Connected Q between the pipe 10 and the spigot 11, 1s a valve casing preferably similar to a globe valve and representedas a whole at 12, and provided with an internal valve seat 13 having a downward-ly opening valve 14 operating in connection therewith. Depending from the casing 12, is an internally threaded boss 15 having a threaded plug 16 engaging therein and formed hollow to receive a spring 17 which bears against the valve 14 and normally retains the same in closed position when the pressure for opening it is removed therefrom. Rising from the casing 12, is an externally threaded sleeve 18 through which a rod- 19 operates and engages the wing portion 20 of the valve 14. The rod 19 is provided with a longitudinal bore 21 having a lateral vent 22 communicating therewith, while the wing portion 2O of the valve is provided with a longitudinal bore 43 in constant vertical alinement with the bore 21 and provided with a lateral branch 43 leading through one of the wings 20, and opening into the discharge side of the valve casing 12.

It will be noted by reference to Fig. 1 that when the rod 19 is in its downward position, the lateral branch 22 will be closed by the packing cap 36 of the casing l2, the Cbject to be hereafter explained.

The casing 12 is likewise provided with bosses 23 in which spaced rods 24 are threaded, and thus stand vertically and in parallel relations to the rod 19. At their upper portions the rods 24 are threaded and provided with an adjustable transverse head member 25 held in position thereon by clamp nuts 26, while an intermediate transverse member 27 engages the threaded portions of the rods and is held in position by clamp nuts 28. The two members 25-27 are thus spaced' apart a considerable distance. At its upper end the rod 19'is provided with a transverse head 29 having a disk 30 of soft metal such as copper in its upper face. The member 25 is provided with a threaded aperture through which a screw or clamping member 31 operates and provided with a wing nut 32 to enable it to be readily rotated. At its lower end the screw 31 is provided with a swiveled' foot release the rod 19 and permit the spring 17 to automatically close the valve 14 and shut oil' the further flow of water. The movement of the spring and valve 14 will elevate the rod 19 and expose the vent 22 abo-ve the packing rap 3G of the projection 1S and thus prevent the creation of a vacuum and per- Ymit the surplus water to drain oli' through rthe vent passage formed by the hores 4t- -1t321 and Q2.' By this simple means it will be obvious that so long as the water remains at a temperature above freezing. the cartridge 35 will remain intact and hold the valve 14- in open position and permit the water to llow, but in event of the falling of the ten'iperature below the freezing point, the cartridge by freezing, and bursting, will release the valve and permit the spring. to close it.

The faucet 1l is provided with a depending hollow boss 37 and provided with an upwardly opening valve seat 38 to receive a small valve 39 which is held water-tight by the pressure of the water in the faucet below the valve 45 of the same. The valve 39 is relatively light and is held closed by the ordinary water pressure but when the cartridge 35 is fractured by the frost and the flow of water automatically cut off by the action of the valve 14, the pressure of water upon the valve 39 will also be reduced so that the outside air pressure will elevate the valve 39 and thus provide a vent to permit the water between the valve 45 of the faucet and the valve 14 to drain 011i" through the vent passage and be thus prevented from freezing in the pipes and faucet section of pipe. The valve 39 is thus inoperative so long as the apparatus is operating under normal conditions, but will be automatically released and become Aeffective to assist in draining the faucet pipe leading thereto when the water supply is cut off, as above noted. y

All of the parts will preferably be of brass or like non-corrosive metal, and may be of any required size or capacity to adapt it to water conductors of various sizes and under various pressures.

Having thus described the invention, what is claimed as new is: t
