UNITED STATES BEST AVAILABLE COPY PATENT OFFICE.
HENRY DEYMANN, OF TOLEDO, OHIO.
SPECmCA'HON forming part of Letters Patent No. 373.969, dated November 29, 1887.
Application filed March it, 1881'. Serial No. 231,160. (80 model.)
To all whom it may concern:
Be it known that I, HEsaY DEYMANN, of Toledo, in the county of Lucas and State of Ohio,have invented a new and Improved Ther- 5 niostat, of which the following is a full, clear,
and exact description.
My invention relates to an improved thermostat, and has for its object to provide an instrument capable of use wherever instruments of that class are applicable, and wherein the construction will be simple and inexpensive.
The invention consists of the combination of parts, including their construction, substantially as hereinafter described, and pointed out i in the claim.
Reference is to be had to the accompanying drawing, forming a part of this specification in which the figure illustrates a side elevation, partially sectional, of the improved thermostat applied to control the supply of gas to a burner.
In carrying out the object of the invention, stand-pipes A A are provided, united by one or a series of horizontal tubes, B, the said stand-pipes and tubes being supported vertically by any approved means.
The stand-pipe A is provided at its upper end with an inzegral air-chamber, B, having a suitable screw-cap, I. A small tube, 0, is made to extend through the said standpipe A up into the air-chamber near the top thereof, the said tube 0 being projected through the bottom of the standpipe and connected with a diaphragm, D.
The diaphragm D is constructed, preferably,
with a metal body, d,having an integral apertnred projection at one side adapted to receive' the tube from the stand-pipe A. The top of the body is covered by a strip, E, of rubber, leather, or other elastic substance, held thereto 0 by a ring, d.
To illustrate the operation of the thermostat a gas-burner, E, adapted for use with a heater, is connected therewith. The burner E is supported above the diaphragm, which burner is provided with an interior valve, e. The valve is adapted to be closed by a needle, e, supported upon the top of the diaphragm D by circular disk e, integral with the lower end of said needle. At the top of the stand-pipe A a capped aperture is provided, through which aperture o nsi lfliquiqLis poured until the horizontal tubes B and standpipes have been filled. When the alcohol expands by reason of the high temperature, it crowds the air from the air-chamber into the 5 air-tube C, the pressure is communicated from said tube to the diaphragm, inflating the same correspondingly, the diaphragm by expansion raises the needle resting upon it, causing the said needle to close the valve e, and when the temperature falls a reverse action takes place, and the needle thereupon drops down to its normal position.
Whenrubber is employed for the d iaphragm illighmiliai li li? 93 "9" F fiilf. 5/ the alco h9l in the air-chamber to cit otf communication between the said alcohol and the diaph'i'ifgi'n and prevent volatilization thereof.
I do not confine myself to the arrangement of the tubes and stand-pipes shown, as the pipes may be formed into a rack, a coil, or a single pipe onlymay be employed running alongthe base-board of a room.
Having thus fully described my invention, what I claim as new, and desire to secure by 7 5 Letters Patent, is-
In a thermostat, the stand-pipes connected together by intermediate tubes, one of said pipes having an air-chamber at its upper end, in combination with a tube extending into the 8c latter stand-pipe and into the upper part of said air-chamber, and connecting with a diaphragm upon which is supported a rod orstem, the upper end of which fits into the flame-pas sage of the burner, substantially as and for the 8 5 purpose set forth.
