AiTTOIViATIC CONTROLLING AND INDICATING- DEVICE.
Application filed April 3,
To all whom it may concern Be it known that we, JOHN J. SARSFIELD and ANTHONY WAYNE DAILY, citizens of the United States, residing at Peoria, in the 5 county of Peoria. and State of Illinois, have invented certain new and useful Improvements in Automatic Controlling and Indieating Devices, of which the following is a specification.
Our invention relates to improvements in automatic devices which may be used for regulating temperatures, as an alarm or indicator to indicate that a certain predetermined temperature has been reached and as a controlling device of general utility and adaptability.
An object of this invention is the provisionof a member which is adapted to be subjected tov a fluid pressure and which is adapted to operate or control theoperatwn of mechanism as the pressure varies.
Another object of dur invention is the provision of a hollow 'member having one end closed and adapted to contain a fluid,
part of the member being adapted to be moved when a change in the pressure of the fluid occurs to operate or actuate a mech anism.
A further object 01" our invention is the provision of such a device which includes as one of the essential elements, a hollow curved arm or member, the varying pressure of the air or gas within said hollow tube or member causing it to move due to its tendency to straighten under the increase of pressure and thereby actuating an alarm,
-malring a suitable indication, or regulating the temperature by controlling valves or other means.
A further object of our invention is the provision of such a device which 18 simple in construction, being composed of. few parts and efiicient in operat on, being susceptible to minute changes in temperature and pressure and being capable of accurate adjustment to meet the various conditions arising in operation.
.To the accomplishment of the foregoing and such other objects as may hereinafter appear, our invention consists in the construction, combination and arrangement of parts hereinafter described and then sought to be defined in the appended claims, referenee being had to the accompanying draw- 5 ings forming a part hereof and which illustrate several embodiments of our invention,

system; Fig. 2 is a vertical section on line can 22 of Fig. 1; Fig 3 is a side elevation,
parts being shown in section of a device constructed according to our invention to serve as a means for indicating and making an audible alarm when a certain point of temperature is reached. Fig. L is a crosssection on line 4-4 of Figs. 1 and 3. Fig. 5 is a fragmental perspective View of the connection between the link 16 and the shaft 18.
Throughout the drawings like and corresponding parts are indicatedby the same reference characters.
@ur invention is founded upon the principle that a curved hollow tube filled with air or other gas will tend to assume a straight position when the pressure of air or gas within is increased over that without, and that it will tend to assume its normal. curved condition when the pressure of the air or gas is correspondingly decreased. We make use of this principle broadly by providing a curved arm. or member, hollow and adapted to contain air or gas, said arm or member being formed of a suitable resilient mate- ,rial so as to permit the desired movement ,1" thereof due to the varying amount of pressure of the air or gas within. In the embodiments of our invention illustrated, the
- free end of this arm or member forms part of the connection for operating the con trolling OI regulating mechanism or is used as a means for releasing or actuating the alarm device.-
Specifically describing our invention, attention is first called to the construction illustrated in Figs. 1 and 2, wherein we provide a casing'or body portion 1, having the inlet and outldt'nipples 2, which are adapted to be connected in a heating system. The casing or body portion is in the form of a curved cylinder and is divided into two parts by means of the removable supporting plate or disk 3, which is adjustably and detachably secured in position by means of threaded engagement of its edges t with the internal threads 5 of the casing. This supporting disk or plate carries all of the'opeu ating mechanism and the valves operated thereby. It has formed thereon the central supporting standard or bracket 6, having the slot 7 therethrough in which is pivotally mounted the equalizing bar or lever 8 to the ends of which are pivotally connected the valve stems 9 of the oppositely arranged valves 10, for which'seats 11 are provided in opposite sides of said supporting plate or disk 3. This provides a particular form of balanced valve adapted for use in devices of this character.
These valves are designed to be operated according to the temperature in the system and in the device and the means for operating the valves includes the curved arm or member 12 which is hollow and substantially elliptical in cross-section, being formed preferably of brass or some other suitable resilient material. The end 13 thereof is closed and proitided with an eye 14 in which is pivotally mounted the right angled extension 15 of link 16, the latter being connected to the lower portion of the depending arm or extension 17 of the pivotal shaft or bar 18 to which the equalizing bar or lever 8 is secured by means of set screw 19. The support 20 for the hollow curved arm or member 12 is :ast orformed on said supporting disk or plate and is removable therewith. This hollow arm or member is adapted to contain ether, alcohol, or any other readily volatilized liquid so that as the heat in said chamber or casing increases the liquid will be gasified increasing the pressure insaid hollow curved arm or member. It is obvious that when the temperature increases above a predetermined point that the increase in ber 12 thereby permitting the tube to return to its normal curved condition, lifting the valves off of their seats and permitting the passage of the heating fluid into the circuit. This condition is maintained until the temperature is raised to or above a predetermined point, when the valves will be closed as previously described.
This disclosure has been particularly to means for regulating and controlling heating systems, but as our device is of general utility we disclose in Fig. 3 a construction adapted to serve as an alarm for heated bearings or hot-boxes, the construction illustrated being particularly adapted for bearings of turbine engines and the like. This construction includes the hollow curved tube, arm or member-25 terminating at one end in the solid portion or extremity 26 and at its other end in the attaching nipple 27. The receptacle or reservoir 28 is adapted to be connected to the nipple. This construction is similar to that described in Fig. 1, but the adaptation is substantially different in that it is used to release the alarm mechanism to give notice when the temperature of the hearing has exceeded a predetermined point. The alarm device includes the ordinary spring motor 29, adapted to reciprocate the clapper 30 of the sounding bell or alarm 31, the stop or abutment arm 32 being adapted to bear against the solid extremity 26 of the hollow arm or rod 25 and being connected to the oscillatory shaft 33 of the clapper member 30. The device. is normally in the condition shown in the drawings, but when the temperature of the bearing exceeds a predetermined point the receptacle 28 and its contents, a readily volatile liquid, being subjected to that heat, the liquid gasifies, producing a pressure in the curved hollow arm or member thereby tending to straighten the same, which action moves the end ofthe arm or member thereby releasing the stop or abutment member 32 so that the spring motor actuates the oscillatory shaft 33 and sounds the alarm on the bell 31, so that the attendant is notified and can take the necessary precautionary measures. When the temperature declines below the predetermined point the device resumes its normal position until actuated again, as described.
It is obvious from this disclosure and description that the device may be adapted to various other uses, and that it is to be considered that our invention involves broadly the idea and principle herein stated and should only be limited to the structure defined in the claims.
What we claim is 1.-In a device of the character described, and; in combination, a body or casing having an inlet and an outlet, a supporting plate or disk detachably and adjustably mounted therein to separate said body or easing into two compartments, said inlet communicating with one compartment and the outlet with the other compartment, openings through said supporting plate or disk, valves controlling said openings, a hollow arm or member mounted ,on said supporting plate or disk and having one end closed and operatively connected to said valves, said arm or member being adapted to contain a fluid the pressure of which varies according to variations in temperature,'said hollow arm or member being adapted to move due to variations in the pressure of said fluid and thereby to actuate said valves to control the passage from said inlet to said outlet.
2. A device of the character described including in combination, a body or casing of cylindrical shape having an inlet and an outlet, said cylindrical ,casing having internal inseam screw threads and a supporting plate or disk detachably and adjustably mounted therein by means of said internal threads to separate said body or easing into two compartments, said inlet communicating with one compartment and the outlet with the pther compartment, a cap for said casing, said supporting plate or disk having a plurality of openings therethrough, one of said openings having a seat on the inlet side of said plate or disk and the other opening having a seat on the outlet side of said plate or disk, said plate or disk having a supporting member bifurcated at its outer end, a lever pivotally mounted in said bifurcation, valves for said seats having stems pivotally connected to said lever, the pivotal mounting for saidlever including a shaft or bar having a depending arm or extension, a curved hollow resilient arm or member mounted on said supporting plate or disk and havin one end closed, said closed end having a lin connection with said depending arm or extension, said hollow arm or member containing a fluid, the pressure of which varies according to variations in temperature, said hollow arm or member being adapted to move due I to the variations in the pressure of said fluid, and thereby actuate said valves to control the passages between said inlet and said outlet.
In testimony whereof we aflix our signatures, in presence of two witnesses.
