To all whom it may conce-rn:

a itknown that I, Cuirr J. BAL-rimani, aA citizen o f the- United States, and resident of Sh Louis,- Missourl, have invented certain new' andaiseful Improvements in Thermo- Static Begulators, of which the following is a -.spec1 ficat 1on containing a full, clear, and egact description, reference being had to the accom' anying 4drawings, forming a part am@ i inventionl relates toa thermostatic ator, and consists of means which op fera/.te automatically to maintain Water or ,othervluid at a uniform temperature by controlling the Supply of heat to said Water or aan.

' 'traction of the airin the chamber due to the changes in temperature of the fluid passing through yand said diaphragm operating a suitable invention further consistsin a double livalled air chamber, 1n one end of which is arranged a diaphragm which is elevated and lowered as a result' of the expansion and conthe doublewalls of Isaid chamber,

mechanical device, such as adamper or valve, the heating mechanism.

, To the above purposes, my invention con sist-sin .certain novel '.features of construction andai-rangement of parts,l which will .be hereinafter more/fully set "forth, pointed out in the claims, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a hot Water tank with my .improved thermostatic regulator attached thereto, and being shown in vertical section; Fig. 2 is a plan View of the regulatpr; Figiis a plan view of the regulator,.with the adjustable ring which carries an 'operating lever removed therefrom. l

Referring by numerals to the accompany# ing 'drawings :-1 designates al hot water tank, 2 the steam pipe leading thereinto,

which provides means for heating the water in said tank, and in which steam pipe is located abalaneed valve 3.

4 designates a double Walled conical chambedr, andA leading into the lower end thereof 'the pipe 1G performs the function from the upper end of the tank 1 is a pipe 5, in which i located a valve 6. Leading from theupper end of the chamber l is a pipe 7, in which is located a valve S, and said pipe T connects with a service pipe 9. Connecting 5 with` the service pipe 9 is a pipe 10, in which is .located a valve 11, which pipe of a by-pass when v 4Specificatie.n of Letters IlaartentT Application iled October 1,

"the thermostatic regulator is out of use, and.

the valves and Sare closed.

`Rigidly fixed in any suitable manner on top of the chamber t a cap 11, and held betiveen the edge thereof and the top of the. conical chamber .L1 is a flexible diaphragm 12, of rubber, or analogous material, and located o n top ofsaid diaphragm is a sleeve 13, which operates through an opening 11iy formed in the center of the cap 11. The arrangement of the diaphragm 12 on top of the chamber 4 .creates an air-tight compartment Within said chamber below said dla-l phragm. -l

IArranged for rotation on top of the cap 11. is a ring 15, and fixed in one side thereof isa bracket 16, in .which fulcrumed a horizontally disposed lever "17. This lever ex- `tends across the top of the cap 11, and its outer end is provided 'with an adjustable weight 1S. A pin 19 is adjustably seated in the ring 15 -opposite the bracket 16 and. serves as a rest for the outer end of the leverl 17 \vhen'the same occupies a horizontal position, and located in the sleeve 13 is a pin 20, .the 'upper end of which is bifurcated and engages the lever 17 between the fulcrum point and the weighted end thereof. The end of the lever 16 opposite. the Weighted end 'is connected in any suitable manner to the stein oi the balanced valve Z.

When my improved regulator is in use, the steam discharging from the pipe 2 heats `Water in the tank 1, and the water thus heated passes through the pipe 5, between the double walls of the chamber 4, through 9. When the temperature of the Water rises above the normal degree, the air o n thev interior of the air tight chamber L1 will be the pipe 7, and out through the service pipe expanded by said heat, and, as a result, the' diaphragm 12 will be elevated. This action elevates the sleeve 13 and pin 20, in turn elevating the Weighted .end ofthe lever 17, swinging the same .upon its fulcrurn, and thus operating the balanced valve 3` to cut off, or partiall 1' cut off, t-he passage of steam through thepipe 2, which heats the Water. As the steam to the tank 1 is thus out off or reduced, the temperature in said tank will naturally fall, until the proper degree of temperature is reached, and thus a practically stationary temperature is maintained as long as the' regulatqr is in use. Should inoperative for any for' should it vbe desired to di with the-'use thereof,'the `valves .6 and'8 are closed,`and the-hot water Twill discharge frOmQthepipe thrugh the :by-pass 'pipe 10 direct to thev service pipe. 9.
