IMPROVEMENT IN ELECTRICAL TEMPERATURE-REGULATORS.

Specification forming part of Letters Patent No. 152,031, dated June 16, 1874; application filed March 27, 1874.

To alt whom it may concern: l

Be it known that I, WILLIAM U. BAKER, of the city and State of New York, have invented an Improvement in Temperature-Regulators for Buildings, &c., of which the following is a specication:

The object of this invention is to regulate the admission of atmosphere, in aheated condition or at ordinary. ntegmpemture, in to an apartment, according to thel temperature of that apartment, so that whenthe temperature of the apartment is less than a txeddegree.

warmed air will be admitted, but when it is higher than that degreetherwalllllivir will be Shut Off: all@ 6h01.,eiltlllQDllQQa/illfdlh'lfy temperature, will be admittefljntp the ii. and pass to the apartment in place of the heated air. Y. \l-fw\ This improvement is especially adapted to use with steam heating coils or radiators, but there will not be danger from ire with furnaces, because the heat will be shut oft' at the furnace, andthere will not be heat confined iu the air-pipe, as usual when a register is closed at the room.

Iuthe drawing, Figure 1 is an elevation of portions of a building with my improvements applied to regulating the introduction or" atmosphere in connection with a steam-coil, and Fig. 2 is a plan ofthe circuit-closing thermostat.

- The floors a b representportions of any building in which this apparatus is applied. The case d is made to contain a steam or hot-water coil, radiator, or a heater of any desired character, and the air passes into 'this case through the trunk e, which preferably receives a supply of atmospheric air from outside the building. The truuk for ue leads the heated atmosphere from the steam-coil to the room or apartment to be heated. The trunk or flue g unites with the flue f, and at the junction a damper, h, is placed that should be balanced so as to swing easily, and either close the warm-air flue fand open the cold-air lue g,

or vice versa. a crank-arm and connection to the armaturelever i of the electro-magnet 7c. The thermostat l is, by preference, made of a coil composed ot' two flat strips, one ot' steel and the other of brass or similar metals, and the inner end ot' the coil is connected with the arbor of the hand fm, and upon the dial are figures denoting degrees .of temperature, so located that when the atmosphere of the apartment has attained the temperature designated the coil shall have expanded and its end moved sufficiently to close the circuit from the battery through the point o, andthereby energize the electro-magnets 7o and move the damper h, closing the warm-air tlue and opening the coolair iiue g. y

'Vhen the temperature has descended sufficient to cause the moving end of the thermostat to leave the circuit-point o, t-he circuit from the battery through the electro-magnet will be broken and the armature-lever t' liberated, so that the damper returns to the normal position, and opens the warm-air lue and closes the cold-air flue.

1,' however, do not confine myself to this particular construction of thermostat.

By this means the temperature of an apartment or building is regulated automatically, and, by the peculiar construction of the thermostat, the point at which the admission of hot air is shut oi' can be determined with great facility by simply moving the hand to the corresponding number on the dial..

I claim as my invention- The combination of a thermostat circuitcloser and an electro-magnet with a damper and heated and cold air pipes, substantially as and for the purposes set forth.

Signed by me this 23d day of March, A. l). 1874.
