DlSTANT-TEMPERATURE INDICATOR.
SPECIFICATION forming part of Letters Patent N0. 375,208, dated December 2OI 1887.
l Application filed July 2l, i857. Serial No. 244,859. (No model.)
.To @ZZ whom it may concern:
Be it known that I, CHAnLEs G. SHORT, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Temperatiue-Indicators; and I do hereby declare that the following is a full, clear, and exact de scription thereof.
My invention relates to devices for indicating the temperature of apartments; and it consists in inducing a current of air from a distant point to come in contact with an inclosed but visible thermometer, as will be hereinafter described with reference to the accompanying drawings, and subsequently claimed.
In the drawings, Figure l represents a device employed in carrying out my invention, said device being applied to aschool-house or other building; Fig. 2, a vertical transverse section,shoWing the upper end of a conductor that forms a part of the device; Fig. 3, a horizontal section of the conductor; Fig. 4, a horizontal section taken on line 4. 4, Fig. 1; Fig. 5, a modilication.
Referring by letter to the drawings, A represents a box that has one or more transparent sides, a, said box being ordinarily located in the basement of a building, as shown in Fig. l, so as to be readily accessible to the janitor or engineer, and constructed in such a manner or of such material as to be non-conducting. The box A,as shown,is divided into compartments b, each of which corresponds with an upper room, B, of the building; but a separate box may be employed for each room,or two or more compartment-boxes may be utilized, the num- .ber of boxes being immaterial.
In each compartment b of the box A is secured a thermometer, C, the latter' being so ar ranged that its lface may be readily seen through at least one transparent side of said box.
Connected to each compartment b of the box A, and extending therefrom up into one of the rooms B of the building, is a conductor, D, that preferably consists of an outer pipe, c, inner pipe, d, and suitable packing, c, interposed between said pipes, as best illustrated by Figs. 2 and 3. The object of the outer pipe, c, and packing e, forming component parts of the 5o conductor above described, is to insulate the inner pipe, d, from external air, and while I prefer to use saidouter pipe and packing, the same may be omitted and said inner pipe covered by or made entirely of asbestos or other good .non conducting material. The inner pipe, d, of the conductor is preferably provided with a funnel-shaped mouth,f, and over this mouth I arrangeashield, E, of wire-gauze or other analogous material.
Fitted in the bottom ef each compartment b of the box A isa branch pipe, F, that connects with a main pipe, G, the latter being designed to connect with a furnace, chimney, or other source of draft. In carryingout myinventiou, by the employment of a device such as I have just described air from the upper rooms of a building is drawn by suction down the con ductors l) in to the compartments b of the'box A and out through the pipes F Gto the point of discharge. The current-s of air thus established pass over thethermometer C in the boxcompartments, and consequently each thermometer is caused to indicate the temperature in the room corresponding to the compartment in which said thermometer may be located.
In Fig. 5 I show a section of tubing provided with atransparency,a,and having athermometer, O, inclosed therein. Communicating with this section of tubing is a conductor, l), and draft-pipe F, the general operation of this latter form of device for carrying out my invention being substantially the same as the one previously7 described.
By the employment of a device or devices such as I have shown and described the degree of heatin each room of a building can be indicated at one point readily accessible to the j anitor or engineer,and as thelatter does not have to leave his post to ascertain the temperature of the different rooms the heating apparatus can be quickly regulated to give more or less heat in any particular room or rooms.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is;-
l. A device for indicating the temperature of apartments,that comprises an air-passage insulated from external air and having its ends, respectively, communicating with an apartment and a source of draft, and a thermometer ICO inclosed but visiblein the air-passage at apoint remote from said apartment, substantially as set forth.
2. A device for indicating the temperature of apartments,that comprises a transparent receptacle, a thermometer located in the receptacle, a tubular conductor insulated from external air and arranged to connect said receptacle with a distant apartment, and a pipe leading from this receptacle to a source of draft,where by a current of the air in the apartment is isolated and caused to come in contact with the thermometer at a point remote from said apartment, substantially as set forth.
3. A device for indicating the temperature of apartments,that comprises a receptacle having one or more transparent sides,a thermometer located in the receptacle, a tubular conductor insulated from external air and arranged to connect said receptacle with a distant apartment, and a pipe leading from this receptacle to a source of draft, whereby a current of the air in the apartment is isolated and caused to come in contact with the thermometer at a point remote from said apartment, substantially as set forth.
4. A device for indicating the temperature of apartments,that comprises a receptacle having one or more transparent sides and divided into two or more compartments, a thermometer located in each compartment, a series of suitable conductors, each leading from an apartment'to acompartment ofthe receptacle,a main pipe leading to a source of draft, and a series of branch pipes connecting said compartments and main pipe, substantially as set forth.
5. A device for indicating the temperature of apartments, that comprises a receptacle having one or more transparent sides, a thermometer located in the receptacle, a conductor leading from an apartment to said receptacle and consisting of an inner and outer pipe separated by a suitable packing, and an outlet-pipe leading from the receptacle to a source of draft, substantially as set forth.
6. A device for indicating the temperature of apartments, that comprises a receptacle having one or more transparent sides,a thermometer located in the receptacle, a suitable conductor leading from an apartment to said receptacle, a shield of Wire-gauze or analogous material arranged to cover the mouth of the conductor, and a pipe leading from the receptacle to a source of draft, substantially as set forth. Y

In testimony that I claim the foregoingl have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
