' UNITED STATES' PATENT OFFICE f FIREPLACE 'HEATER l David H. Lamar, Fairmont, W. Va. Application January 139-, 1943, Serial No. 472,881
l1 claim. (01.126-121) My invention relates to fireplaces vand has among its objects and advantages the provision ef an improved heater designed to circulate air ythrough the re bed and deliver the heated air to the room, this air being .collected before it is ject into the room. AA bracket 48 is. attached to the frame 26,-,which bracket is provided with an opening 50 through which the pipe 46 is proi -jected for support.
heated from a' point close to the floor line beneath the grate of the fireplace. In the accompanying drawing:
Figure 1 is la face View of aconventional ireplace showing my invention applied thereto. Figure 2 is a verticalsectional view. p Figure 3 is a plan view of the grate and the greater part of my heater.
Figure 4 is a perspective view of the heater,
Figure 5 is an enlarged sectional view of a part of the heater showing a mount therefor.
In the embodiment of the inventionseiected for illustration, I make use of a conventional replace I0 within which I mount a grate, I2.
vThis grate comprises a frame I4 provided with grate bars IB. The two end bars I8 of the frame I4 extend upwardly considerable distances and are providedzwith anges 20 having hooks 22 engageable over pins 24 attached to a metal face frame 26 of the fireplace.
Horizontal grille bars 28 are two bars I8. All the bars at their forward ends and attached to the I6 extend upwardly are attached tothe lowermost grille bar 28. Vertical brace bars 30 are attached to and extend between the respective bars 28. All the bars are cast or welded into a unitary structure. l n
Two-rings 30 are attached to the bars .I8 and some of the bars I6 to support an air circulating heater 32. This heater comprises an inverted U-shaped pipe 34 provided with a iiange 3B on each of its two legs 38. The legs 38 fitv in the rings 30 and the anges 36 rest on the rings to support the open ends of the legs 38 vso'rne distance above the ash pit iioor 40 to collect cold air beneath the grate structure.
A vertical tube 42'communicates with the pipe 34 and connects with an elbow 44 to which is connected a short pieceof pipe 4B bent `to prorather than passing into by the grate, and
vcause warm air to circulate upwardly through the pipes 42 and 46 and into the room. vThe pipe legs 38 collect cold air underneath the grate structure and close to the floor surface, which air is returned in a heated condition to the room theiiue. Such a construction increases the room heating efliciency of the replace.
Without further elaboration, the foregoing will so fully explain my invention, thatothers may, by applying current knowledge, readily adapt the same for use under various conditions of service.` v
I claim: v
A heater for a iireplace having a grate there- `in, comprising an air circulation and heating conduit system having two spaced vertical sections supported by and passing through and beneath the grate near the ends thereof to admit cold air thereto from below the grate, and partially heat the same, a horizontally disposed conf j duit section connecting the spaced rvertical sections at their tops and extending through and above the grate in proximity with the hot fuel therein to heat the cold air .entering the spaced vertical sections, a verticalI conduitconnected with the horizontal conduit at a mid point between' its ends, and extending within the heated areaof the fireplace `and a forwardly and upwardly angled conduit section attached to the verticalsection for discharging hot air to a room, said spaced vertical sections having supporting iianges engaging supporting rings carried the forwardly and upwardly angled section supported by a bracket carried by the replace to mount the heater therein.
