FIREPLACE AIR HEATER Filed Jan. 9. 1930 5 Shets-Sheet 3 gave/M501 was mp: M S. Quzrzlz'verz wot/M0430 Patented Nov. 25, 19 30 ,UNITED "STATES- MATTHEW' s. ,oUINmvEn, oELLos ANGELEsc-Amronnm FIREPLACE AI'E. HEATER Application filed January 9, 1330.. Serial No. 419,617.
The invention relates to improvements in 1 fireplace air heaters and -it-aims to provide a new and lmproved construction, 1n which effectlve provision 1s made for the heating and Q circulation of air,'so that the heater not only radiates heat from the fire and the hot metal, but produces added efficiency by means of circulated hot air currents.
With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.
Fig. 1 is a front elevation partly in vertical 1 section.
Figs. 2 and 3 are vertical sectional views on lines 22 and 3-3 respectively of Fig. 1.
Figs. i and 5 are horlzontal sectional views substantially on lines 4-41 and 55 respectively of Fig. 1.
Fig. 6 is a fragmentary front elevation partly in section, showing a modification.
The form of construction illustrated in Figs. 1 to 5 will first be described, and it may be explained that while in both forms of construction shown, I have illustrated most p arts as if cast in a single body, it is to be understood that the structure may be formed from separate sections bolted or otherwise secured together, and that some of said sections may be of heavy material such as cast iron or steel,
whileothers may be of lighter constructions, formed either totally or partially from comparatively thin sheet metal. Such variations are merely mechanical and are nottherefore illustrated.
- The numerals 8 denote two hollow verti cal front posts each having a horizontal partition 9 near'its lower end, cool air inlets 10 and a cool air outlet 11 below said partition, and a hot air inlet 12 and'hot air outlets 13 above said partition, the outlets 13 being above the inlet 12. The inlets 10 and outlets 13 are preferably disguised by appropriate gratings or the like which may be effectively worked in with the designs of the posts.
Extending between and'secured to the lower portions of the posts 8, is a horizontal c001 air-receiving flue 14 having forwardly turned ends 15 communicating with the cool turned ends 15.
,entersthrough the inlets 10, passes through "the cool airoutlets 11 into the front fine 1 air outlets 11 of said posts. Behind thisfiue 14, isa hollow back wall 16 whose upper port1on may beturned forwardly as at l7, if desired; Two'vertical end walls 18 are secured at their rear portions to the rear wall 16, said '55 end walls being hollow and in communication with said rear wall, 16, including its portion 117. The upper front portions of the walls 18 are preferably reduced in height as.
indicated at 19, are secured to the posts 8 and to communicate with the hot air inlets 12 of said pests. 'Tlie lower portions of these walls 18,
at the front endsof the latter, aresuitably securedto the flue 1 1 atthejunctures of the,
forwardly =15 main portion of ,this flue with its A front to-reari-flue 20telxtends from. the
lower central portionof the frontflue 14 to the lower centralportion of the rear wall 16 and communicates with said flue 14: and wall 516. Also extending between the. flue 14 and wall 16, is a grate 21of any desired construct-ion, .saidflue andwall being provided with appropriate ledges 22 upon whichthe grate rests. TBy preference, this grateis positioned above the flue 20.
' Either a solid fuel fire maybe built upon .the grate .21, or a liquid or gaseous fuel burner may be placed upon said grate with appropriate l-ie'at-conducting material gextend- "'80 ing from the burner to the grate portions 14,
16 and .18.".Consequentl these parts become highly heated to effect heating and'circulation of air. Cool air from the room is heated within the latter, then passesrearwardly through theflue 20' and is further heated in the latter The warm air from flue 12 0 is received in the back wall. 16 and from this wall travels into the end walls 18, being thus heated to high temperature. The-hot air enters the upper portions of the posts 8 through the hot airinlets 12, and discharges through theoutlets 13 into the room. By ta-king'the relatively cool air into the lower portion of the structure and discharging the hot air from its upper portion, a continual and desirable circulation of air is effected in the mom; Moreove attained, by
no cool air inlets. Instead, the front or any desired portion of the flue 14, is provided with appropriate inlets 10 for the cool air. Otherwise, the construction may be considered the same as that above described.
It will be seen from the foregoing that novel provision has been. made for carrying out the objects of the invention. The various details disclosed may be followed if desired, but within the scope of the invention as claimed, variations may be made.
I claim 1. A fireplace air heater comprising two hollow vertical front posts each having a relatively low hot air inlet and a comparatively high hot air outlet, a front horizontal cool air receiving flue extending from one of said posts to the other, a hollow rear wall behind'said front flue, a front-to-rear flue extending between and communicating with said front flue and said rear wall, two hollow end walls secured to and communicating with said rear wall,'the front portions of said end walls being secured to said posts and communicating with said hot air inlets thereof, and a grate extending between the lower portions of said back wall and said front flue. V
2. A fireplace air heater comprising two hollow vertical front posts, each of said posts having a horizontal partition near its lower end, a cool air inlet and a cool air outlet below said partition, a hot air inlet above the partition and a hot air outlet above said hot air inlet; a front cool air receiving flue extending horizontally between said posts and communicating with the cool air outlets thereof, a hollow rear wall behind said front flue, a front-to-rear flue extending between and. communicating with said front flue and said rear wall, two hollow end walls secured to and communicating with said rear wall, the front portions of said end walls being secured .to said posts and communicating with said hot air inlets thereof, and a grate extending between the lower portions of said back wall and said front flue.
3. A fireplace air heater comprising two hollow vertical front posts, each of said posts having a horizontal partition near its lower end, a cool air inlet and a cool air outlet below said partition, a hotair inlet above the partition and a hot air outlet above said hot air inlet, a front horizontal cool air flue having forwardly turnedends secured to said posts and communicating with said cool air outlets thereof, a hollow back wall behind said front flue, a front-to-rear flue extending from said front flue to said rear wall and communicating with both thereof, hollow end walls whose rear portions communicate with said rear wall, the front ends of said end walls being reduced in width and communicating at their upper corner portions with said hot air inlets of said posts, the lower front portions of said end walls being secured to said front horizontal flue at the junctures of its body and end portio'ns, and a grate extending between said front flue and the lower portion of said rear wall.
In testimony whereof I have hereunto affixed my signature.
