AUTOMATIC STOVE-DAMPIER.
SPECIFICATION forming part of Letters PatentNo. 737,086, dated August 25, 1903,
' Application filed Augu stl8,1902. are: Nu. 119,991. (Noruoclel-l T aZZ whom it may concern:
, Be it known that I, THOMAS BENJAMIN DEN- TON, a citizen of the United States, and a resident of Sebree, .county of Webster, and State ofKentucky, have invented certain new and useful Improvements in Automatic Stove- Dampers, of which the. following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar characters of reference indicate corresponding parts.
This invention relates to automatic stovedampers, the object thereof being to'provide a device of this character which is so constructed as to automatically close under a high pressure of heated air and which will also automatically open when the pressure of heated air is reduced by reason of a lowered condition of the fire, thus providing an efficient means for equalizing the temperature of the stove, whereby a considerable saving of fuel is effected.
The invention will be hereinafter fully described, andspecifically set forth in the annexed claims.
In the accompanying drawings, forming part of this specification, Figure 1 is a vertical sectional elevation of a part of a stove having my improved damper connected therewith and shown in normal open position; and Fig. 2 is a sectional elevation taken on the line a: as of Fig. 1, showing thedamper closed.
In the practice of my invention I provide a damper A, embodying a metallic plate having the tapered lower edgeo, to form an anti-.
- rod A, which is extendedfrom the damper A. The said rod A is provided with a screw-.
threaded part a, which engages a counterbalan ce-weight O. This weigh-t is adjustable on the rod A for the purpose of gaging the device, so that the damper canbe set to close in a certaintime by a predetermined condition of heat in the stove.
' In the operation and use of the invention the weight C is set on the red A in such position that the damper A is balanced in normal. open position,- as shown in Fig. 1 of the drawings. The plate B, closing up the space between the plates B, the front of the lower edge a of the damper-plate A and the wall of the flue 1 will cause the products of combustion and hot air coming from the flue instead of partly passiu g under the said dam per-plate to nearly all impinge on the front thereof, pass over its upper edge and from thence into thepipe. This condition of the damper is maintained until the products of cor'nbustion and heated air passing from the fire-box through thefiue 1 attain sufficient pressure to close the damper up against the plates B, as shown by Fig. 2 of the drawings, whereby the draft is cut off and the pressure keeps the damper closed until the fire is allowed to go down to a certain extent. Then when pressure is decreased by'alowered condition of the fire the damper will again assume its balanced open position, whereupon the, closing operation may be repeated. By this means the heat of the stove is maintained in an equalized condition and a considerable saving of fuel is effected, the highly-heated air .being contained within the stove and not allowed to escape through the pipe.
. I do not confine myself to the specific details of construction as herein shown and described, as it is obvious that under the scope of my invention I am entitled to the necessarystructural variations required by stoves of various characters. Y
Having now describedmy invention, what Iclaim as new, and desire to secure by Letters Patent, is-- I 1. Ina stove-damper, the combination with the flue 1,-the plates B thereon and'notched as specified, and a damper-plate Working in said notches, of the plate B, closing the space between the lower edge of said damper-plate, the plates B, and the wall of said fine, and
preventing hot air and products of combustion, coming from said flue, from passing under said damper-plate.
2. In astove-dainper, the combination with the flue 1, the plates B, thereon and notched as specified, and a damper-plate Working in said notches, of'the plate B, having notch 12', and closing the space between the loweredge of said damper-plate, said plates B, and the wall of said flue, and preventing hot air and the products of combustion coming from said
