The upper cover 6 is pivotally mounted and the lower damper is closed. This condition so that the cover 6 is normally open, and insures of. the dampers checks the draft through the room From the above description it will be seen that I Y have provided a. simple and efifective damper regulating device for automatically controlling the temperature of rooms. The device is positive and noiseless in operation, having few parts so mounted that they will not get out of order.

'The device can be readily and conveniently installed on any furnace in a short time without material alteration of the furnace.

The foregoing disclosure is to be'regardecl as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed ineluding-many modifications without departing fromthe general scope'herein indicated and denoted'in the appended claims.

Having thus described my invention what I claim as. new and. desire to secure by Letters Patent, is: v

1. In an automatic damper controlling device, a'casing having a cover pivotally mounted off centerthereon, a boxmounted on the underside of the casing, 'anda solenoid mounted in the box, a core'slidably positioned in the solenoid, and'resilient means connecting the core to the cover.

2. In an automatic damper controlling device,

a casing having a cover pivotally mounted 01f center thereon, a box mounted on the underside of l able easy cleaning of the solenoid.

. 3. In an automatic damper controlling device,

a casing having a cover pivotally mounted off center thereon, a solenoid mounted on the casing, a core slidably mounted in thesolenoid, and spring means connecting the core to the cover, said-cover being maintained normally in a predetermined position by gravity. 4. In an automaticdamper controlling device,

a' casing having a cover pivotally mounted off center thereon, a box mountedon the underside of the casing, and a solenoid mounted in the box, a core slidably positioned in the solenoid, and

means connecting the core to the cover at all times.

5.'In an automatic damper controlling device, a casing'h'aving a cover pivotally'mounted off center thereon, a box mounted on the underside of the casing, and a solenoid mounted in the box, a core slidably'positioned in the solenoid, and means connecting the .core to the cover at all times, said box having an opening in its bottom to enable easy cleaning of the solenoid.
