DAMPER REGULATOR.

To all whom it may concern.-

'Be it known that I, DOCTOR FRANKLIN MORGAN, a citizen of the United States, re.

siding at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Damper-Regulators, of which the following, when taken in connection with the drawings accompanying and forming a part'hereof, is a full and complete. description, sufiicient to enable those skilled in the art to which-it pertains to understand, make, and use the same.

The object of this invention is to obtain an apparatus by means of which a determined variation in temperature of a confinedbody of air will produce movement of a'piston or connecting rod, and thereby perform desired work, while at the same time means are provided sojthat if any considerable quantity of such air escapes from the confining vessel when the temperature thereofis raised and the pressure :thereof is above atmospheric pressure additional air will be automatically supplied to such vessel when the same is at atmospheric temperature, thereby insuring continuous and uniform operation of the apparatus. i

A further object of this invention is to obtain an apparatus ofwhich the operation will be uniform.

Figure 1 of the drawings referred to as forming a part of this specification illustrates an apparatus embodying this invention in vertical sectional view with an elevation of the front of a heating apparatusand with a plied to such cylinder when required while the cylinder and contents are in a cooled condition.

A is a cylinder closed at the upper end by the head a and at the lower end by a movable wall in base B. Base B consists of the parts I) b. C is a diaphragm forming a movable wall secured in place between such parts I) b.

Parts I) b are respectively provided with apertures therein. Such aperture in part b Specification of Letters Patent. Application fi led April 27,1905. Serial 1%. 257,749.-

which water or other liquid.(lettered F) may flow from cylinder A into the space between l) b of the'head Band phragm C. v v

F is a lever pivotally mounted on fulcrum f. I v

G is a connection'between leverF and the under side of diaphragm C.

in contact with 'dia g is a pin in connection G, against the under 1 sideof which the lever F is held by weight H. Weight H is adjustable on the lever F.

I is a pipe connected, by means ofpipe J, to 5 the steam-supply of the heating system in which'this apparatusis placed, and K is a steam-discharge pipe connected to the lower end of pipe I.

L is an ordinary venting-valve attached to pipe Kby pipe Z and permitting air to flow therethrough from pipe K, while preventing water of condensation or steam to any con-. siderabl'e amount flowing therethrough M is the discharge-pipeofventing-valve L.

' Whenthe apparatus embodying this invention 1s attached to a steam-heatingdevice wherein an exhaust-pump is used, the

of such pump, while in other vacuum steamhe ating systems such pipe mmay be connected to the aireduction pipe.

N is aclosed cup arranged to hold merpipe M may be attached to -,the exhaust side cury or other liquid, and O is apipe establishing communication between the cup N and the interior of cylinder A. y

P is a vertical pipe communicating with the cup atit's lower endand open into the cup Q at its upper end. Cup Q is open to the atmosphere. a a

R is a flexible cord attached .to lever F at one end and extending from thence over the pulleys S Sand attached at its other end to damper T of the steam-generator U, as at t.

The apparatus is shown in the drawin s with the air which constitutes the expansib e member operating the device and which is contained in cylinder A expanded so that the damper is closed. At such time the expansion of the air forces the liquid E against diaphragm C and also forces the mercury containedin cup N into pipe P until a sufficient uantity of such mercury is in such pipe P (as to balance the pressure in cylinder A. If

the pressure in cylinder A is suflicient, all the mercury in cup N may be contained in pipe P and cup Q, and any additional pressure in cylinder A will force some of the heated air therein underneath the mercury in pipe P, whereupon such air will rise through the mercury and escape to the atmosphere.

When the contents of the cylinder A are cooled and the pressure in such cylinder thereby reduced, mercury in pipe P will flow into cup N therefrom, and in case any heated air from the'cylinder hasescaped through ipe P, as above described, additionalair will W into the cylinder A to replenish such cylinder. I

The air constituting the expansible member ofthis apparatus in cylinder A is warmed by steam or water of condensation flowing through pipe I. In case air is contained in pipe 1 when steam or water of condensation enterssuch pipe through pipe J such air will flow into pipe I through venting-valve L and into pipe M.- The venting-valve L is supplied to prevent the trapping of air in pipe I, as might occur if the end of pipe K were closed by water of condensation.

Liquid Eis used to prevent the heated air -.of cylinder A coming .in' contact with diaphragm C.

In the operation of this apparatus steam in pipe I heats the air in-cylinder A. When the heated air forming the expansible member in .cylinder A cools, as by the cooling of the contents of pipe I and the radiation of heat from cylinder A, such air contracts, the pressure thereof on liquid E is thereby lessened, and theweight H on lever F will turn such lever on fulcrum f to raise connection G and diaphragm C and also to raise damper T of steam-generator U.

.= The pipe P is of suflicient height to hold a column of liquid requiring a pressure to sustain it equal to the pressure desired in cylinderA when the air therein is heated. Hence when water is substituted for mercury V as the liquid'therein (as it may be) the pipe P must be at least, say, thirteen and six-tenths times as long as it is when mercury is used, and cup N must be proportionately large.

- Havingthus described. my invention, what I claim as new, and desire to secure by Let- .terfs Patent, is

L 1; A=receptacle provided with a movable wall, means to automatically limit pressure of heated an in the receptacle, and to automatlcally replenish, when the an 111 the receptacle is cooled, air forced from the receptacle when heated, means to raise the temperature of the air in the receptacle to above climatic temperature, a damper, a fulcrumed lever, a connection between the lever and the damper and a connection between the lever and the movable wall and nieans to vary the pressure of the connection against such movable wall.

2. A receptacle provided with a movable wall, means to limit pressure of heated air in the receptacle, and to automatically replenish, when the air in the receptacle is cooled, air forced from the receptacle when heated, a pipe to convey heating fluid, such pipe extending through the wall of. tho'casing thereinto and therefrom and means to vent such pipe of the air contained therein, a fulcrumed lever, a connection between the lever and the movable wall, and means to vary the pressure of such connection against the movable wall.

3. The combination of a two part base, each part provided with a hole therethrough, with a diaphragm secured between the parts, a cylinder closed at its upper end attached. to the upper one of the parts, such cylinder arranged to hold liquid and air, a pipe for heat ing fluid extending through the side wall of the cylinder into and out thereof above the liquid therein to control the temperature of the air contained in such cylinder, a seal, and a communicating way between the seal and the interior of the cylinder.

4. The combination of a two part base, each part provided with a hole thercthrough, with a diaphragm secured between the parts,

a cylinder closed at its upper end attached to the upper one of the parts, such cylinder arranged to hold liquid and air, and a pipe for heating fluid extending to and. connected with the cylinder above the liquid. therein. to control the temperature of the air contained in such cylinder.
