Description

ing a heat of great intensity.

the fire-pot to the interior of the stack is regulated. An upright arm 16, formed by turning at a right angle the end ofthe wire.VV

constituting the pintle of the hinge, has one end cf a forwardly extending rod 17 pivotally connected thereto, and a hook or bill 18l formed at the front end of said rod is adapted to be directed iuto one of a Aplurality of spaced holes 19, provided in an outwardly directed flange Q0 carried by the cover 6, for maintaining the damper in adjusted position. y

For preventing lthe flame resulting from combustion of the gas within the stacky from dropping back to the surface ot the oil within the reservoir 4, a circular netting or screen 2l of wire is preferably employed, the same being removably seated upon the top of the conduit 8. Said screen has one or more openings, as 28, provided therein adjacentto its periphery to permit of the pas- Sage therethrough of flame from the fireot 3i p Mounted at a'suitable point in the cover 2 over the reservoir is an upwardly tapered filling tube 23 which projects outward through an opening 24 provided in the cover G. By removal of a covering or c ap 25 provided for'said tube, thereservoir may be readily filled, or the fuel replenished without disturbing any of the heater parts and 'without the necessity of extinguishing the fire. The lateral edges of the cover 6 are downwardly inclined and terminate in hooks 2G-which lare adapted to be sprunginto Aclasping engagement with the lateral edges or beads 27 of the receptacle 1, as shown in Fig. 4.

In practice, the oil within the lire-pot is ignited, and the flame and heat resulting from the combustion are directed orwar between the covers 2 and 6 and into the stack 7, sis/indicated lby arrows in Fig. 3, passing through the annular passage surrounding the conduit 8 and through the opening 28 in thev screen Q1. ln passing Vthrough the restricted passage between the covers 2. and (i much heat is absorbed by the cover 2 and is thereby communicated to the oil inthe reservoir et, resulting in a rapid vaporization of said oil. The-,vapor or gas thus generated in the reservoir is conducted upward through the conduit 8 and netting Qlrto the stack, wherein it meets the flame from the re-pot and is consumed, produc- As the gas passes through said conduit it becomes mixed with air admitted through the pipe 14. By adjustment of the damper l5 the combustion and amount of heat generated may be readily controlled, the rapidity of' combustion being dependent upon the volume of air admitted past said damper. To extinguish the, fire in the fire-pot, said damper is completely closed.

'the heaters are prepared for shipment.
