MILTON HAIN, OF WERNERSVILLE, PENNSYLVANIA.
TIME DAMPER MECHANISM FOR FURNACES.
SPECIFICATION forming part of Letters Patent No. 632,939, datedSeptember12, 1899.
Application filed June '7, 1899.
tion with the accompanying drawing, which shows my improved apparatus applied to an ordinary form of heater.
A represents the body of a heater, B the fire-door, and G the ash-pit door, the latter being provided with an arm 0 which is connected bya cord or chain c to one end of an ordinary lever c, which is pivoted to a fixed point 0 and the opposite end of which is provided with a weight a, tending to normally open the door 0.
My apparatus comprises a cord or chain .g, one end of which is connected to the fire-door B and the other to a weight h, which is adapted to normally close said door, the chain 9 being passed over guide-pulleys f and c, mountedin a frame d, fixed to the front of the furnace, as shown. This weight it also pulls upon a branch cord or chain g, which passes over suitably-located pulleys i 'i and connects at its end 9 with a pivoted lever j, the free end of which is engaged when in the set position indicated in the drawing by a trigger-pin Serial No. 719,727. (No model.)
Another branch 9 of the weighted chain or cord connects with one end of the weighted lever c. A spring q is preferably employed in connection with this lever c, as shown, to prevent a jarring stop of themoving parts.
In fixing the fire for'the night, for instance, the lever j is locked by the trigger-pin 70, as indicated, thus raising the weighted end of the ash-pit door 0 may be closed and the fire door B opened. The clock mechanism is then ger-pin kv from its engagement with the 'lever j at a certain time, the result of which release is that the weight it will drop, thus directly closing the door B and slacking the chain or cord g so as to permit the weighted end of the lever c to drop, thereby opening the ashpit doo'r, thus applying full draft to the fire. What I claim is The combination with a stove or furnace of the weighted lever 0 connected with the ashpit ,door, 'the weighted main cord g passing overa series of guide-pulleys and having one branch 9 connected with the weighted end with thevfire-door, a spring q having a cord connection to said weighted lever and adapted to control the fall of the connected ashpit door, a trigger connected to the opposite. end of said main cord, and a clock mechanism arranged to release .said trigger, all substantially as set forth.
