Application September 16, 1946, Serial No. 697,219

1 Claim. 1

My invention refers to a hot air compartment heating system wherein a fuel stoker is employed.

The primary object of my invention is to provide, in conjunction with a stoker fan, means for supplying a forced feed of air to lazy distributing flues of a system wherein certain of said fiues fail to supply the proper amount of heat due to their position or length.

A further object of my invention is to provide pipe controlled means communicating with an air delivery duct and the stoker fan air pipe whereby a forced feed air is directed to one or more of the heater flues.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

The drawing illustrates a side elevation of a heating system embodying the features of my invention with parts broken away and in section to more clearly illustrate structural features.

Referring by characters to the drawings, l indicates a hot air furnace provided with a stoker equipment 22 of any standard type. The stoker is provided with the usual worm drive 3 for delivering fuel from the stoker hopper to the burner portion thereof. The stoker is also provided with the usual motor driven fan 4 having a stoker air pipe 5 connecting the fan and the burner proper.

The dome of the furnace is provided with the usual series of hot air distributing flues 66 which fiues communicate with various rooms of a dwelling or compartment, indicated by the numeral A.

An intake air duct 1 also communicates with the compartment and the bottom portion of the furnace all of which mechanism is of standard type.

My improved construction embodies an air suction pipe 8 having an upwardly inclined mouth 8' in communication with the intake duct 1 and the opposite end of this pipe is directly connected to the central portion of the fan casing 4'.

One or more of what might be termed defective or lazy fines, is connected by a comparatively restricted feed pipe 9, which pipe communicates with the stoker air pipe 5 and one of the hot air fiues 6.

The forced feed pipe 9 is also provided with a branch pipe 9', of which pipe communicates diin the pipe 6, the valve 10 will be moved to open a direct passage of air from the stoker air pipe 5 to said flue, whereby a portion of the air drawn by the fan from the duct 1 will be discharged directly into the lazy flue to create a forced feed of hot air from the mouth of the flue 6 to the compartment under which conditions the defective flue is remedied. In instances where none of the fiues are lazy the flow of air from the forced feed pipe 9 may be directed into the dome of the furnace, whereby all fiues will receive the maximum amount of hot air delivered to the dome of the furnace by the auxiliary forced air draft.

It is understood, in some instances I may, without departing from the spirit of my invention, employ the suction pipe mechanism without combining it with the air supply pipe 9, or visa versa.

I claim:

In a hot air compartment heating system having a furnace including an air intake duct communicating with the bottom of the furnace, hot air compartment fines of difierent lengths communicating with the furnace dome, a fuel stoker associated with the furnace fire pot having a fan, an air supply pipe communicating with the fan and fire pot of the furnace; the combination of an air forced feed for certain of the hot air compartment flues, comprising a restricted forced feed air pipe connecting the stoker air supply pipe and one or more of the lazy compartment flues adjacent the furnace dome, a branch pipe connecting the restricted forced feed pipe and furnace dome and a valve in said forced feed pipe for selectively directing air from the restricted forced feed pipe to the dome or to a lazy hot air flue, whereby an auxiliary current of hot air is discharged from the lazy pipe flue mouth.
