To oil whom it may monsoon:

Be it known that il, @Tio lit'ieominm,' o citizen of the United States, i'eoiding :it Detroit, county ot iiinjyne, finti. gtnte ot" ii/iichigon, have invented eoi'tnin new ond nseltui iinproyeinente in iiioteii-ieateis, [ot which the following is ai specification,

My invention .Pointes to in'iproemento in water hee-,ters and inoie poiticnimiy to onto-- matic means foi* opening e. fit-ive in n Vgee pipe iending to the hornet?, of tho heotei Whenever Water is drown from the pipeo heated hy such burners anni tot closing ottici valve when the Water ceases to he ihiiiifn..

fi further ohjeot oit' my invention is to provide such o construction in the devine that the Weight' lever provided to automatic ally close the gas and weitet' uviiivesi may he so afijusted as to move in :i ifei'tioni piane whatever may be the position oit the temoining ortion of the device.

'iiihen the faucet 5i is opened 'Waiter Wilt tion7 through the pont 529' from the cyiiilfiei" if and thenoe through the Coil 3 and the pipe 2 time ion relieving the pressure on one side off the piston valve 16, it being evident that Water cannot ow through the small perforation 27 as rapidly as it can through the relatively large port 29. The f pressure being now unbalanced on the pispiston Valve -16 the gas valve ll is opened as indicated by dotted lines. Gas will flow to the burners and be immediately ignited by the pilotl light, and the Water as it flows throughwthecoil 3 will be heated by 'said burner. On closing the faucet the Weight 23 which has been 1n a raisedposition during the flow of Water Will drop and close the water and -gas valves automatically, the revision for adjusting said4 Weigl1ton the ever 22 being necessary .to render the device operative with varying Water pressures.

Various slight changes might be made in the general form and arrangement of parts described Without departing from my in venton, and hence I do not restrict myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall Within the spirit andscope of the appended claim. A

H'ving described my invention what I claim as new and desire to secure by Letters Patent is:

In a device of the class described, a cylinder having awater inlet at one end and a large and a small portin the Walls thereof, a 1piston valve adapted to operate in said cy inder having a longitudinal perforation therein smaller than said small port, a head in said cylinder through which a piston rod y provided on said piston valve projects, said @elses small port being located nearer the cylinder head than said large port and adapted to be uncovered by said piston valve when the large port is covered thereby, said large port being uncovered by said piston valve when said small port is covered thereby, said cylinder head being at the end of said cylinder opposite said` Water inlet, a conduit leading from said ports through a water heater to a faucet, a gas chamber having a gas inlet and outlet and a valve seat therein, a gas Valve adapted to seat on said valve. seat and provided with a stem projecting through the side of said chamber, said stem and said piston rod being in axial alinement and sccurely connected together, a yoke adj ustably secured to said cylinder and said chamber having two perforated lugs in which a lever is fulcrum'ed, an adjustable weight on said lever, said lever and Weight being connected with said stem and adapted to automatically seat said gas valve, and a pipe leading from said gas chamber to a pilot light provided in said heater, said gas outlet consisting of a pipe leading from said chamber to the burner of said heater, the admission of gas into said last-named pipe being controlled by said gas valve, and said pilot light being arranged to ignite the gas when supplied to the burner by said lastna1ncd pipe, and said piston valve being adapted lo uncover said large port by water pressure against the resistance of said weighted lever when said faucet is opened, substantially as described.

In testimonyrwhereof .l have signed my name to this specification in the presence of two subscribing` Witnesses.
