BMW, Bryon, @hio Application ems ll, new, Serial No. access to E (cl. res-41c) Tl'lis lglvention relates to worm sir furnaces but more particularly to furnaces which employ mechanical heating devices such as oil burners for generating the heat and an object is to pro time a new and improved furnace of this chor ecter which can be inexpensively manufactured, may be readily assembled, is compact in arrange ment and emciently heats s comparatively large volume of air. ‘ Anotherobject is to produces. warm air fur hoce in which the blower and heating device ore arranged in superposed relation laterally of the radiator in a neat and compact manner at one end portion of the furnace, such that the air is forced. by the blower into the-lower end of the radletcr who. is heated during its upward trevel. platform it, and directly therebenesth on oil burner it. The blower it, which preferably consists of a squirrel‘ cage type fen driven by on electric motor it, draws in cold air through an opening ill in the top'of the shell or we I 5 it through ?lters lit ‘of glass wool or‘other suit~ ' able material and forces the stream oi’ sir into’ e. downwardly rclisposec conduit it which is lusts» posed to the partition ll. ‘ The conduit it is some into two sections by means oi’ a, partition member 2t which extends from one side of the conduit to the other see.

The shell is divir'leti into two vcompostmerits by means of o-tertlcolly dis posed partition M. In one compartment are dis WHERE; ‘ ' ‘ Connected to the projecting lower portions of Eli - the tubes 2t and Joined to each set of three tubes pos'eslthe combustion chamber and radiator til I‘ on that mule is s de?ector or-loeme plate ?t which audio the other compartment‘ are disposed o curves outwsrcily sod downwardly. the lower oor~ blower lt which is‘ ‘on o horiwcntsl tlorl thereof below suhstcwtlelly worsllel to the M 2 2,109,876 adjacent side wall of the shell I0 and being spaced a slight distance therefrom. This de?ects the major. portion of the air into the tubes to but allows some of the air to‘ pass outside of the tubes and belieated by contact with the side walls 21 and associated parts. _The heated air passes up’wardly within the shell ill and through an opening 32 from which may radiate the ducts leading to the various rooms in the building. In this manner, a simple‘ and comparatively inex pensive structure is produced but one which eih- ‘ ciently imparts heat to a very large volume of air introduced to the rear compartment of the shell. As shown in Figure 5, the tubes 29 on each side are spaced from each other and the outer tubes are spmed from the adjacentwells El. This enables the products of combustion inside the radiator to pass upwardly within the combustion chamber C between the tubes and to contact with each side of the tubes over the major portion thereof. Extending reerwardly from the upper end of the combustion chamber housing is a pipe ill which may lead to the ususl smoke stack, providing an exhaust passage for the products of combustion. The arrows on Fig. 5 show the travel oi the gases within the upper portion of the combustion chamber and indicate how the heating oi’ the tubes is accomplished. To insure. that the heated gases or products of 38 combustion do not pass directly to the smoke to clean out that pocket, the baffle plate 3; may be inclined upwardly and rearwardly and thus be removed-access being had thereto through the clean-out opening 39. It is to be understood that numerous changes in details of construction, arrangement and op eration may be effected without departing from the spirit of the invention especially as de?ned in the appended claims. 10 What i claim is: l. A warm air furnace comprising a. shell, a. partition dividing said shell into inner and outer portions, a combustion housing within the inner portion of said shell, means providing a conduit leading from the upper to the lower portion oi’ said shell for admitting cold air, a platform di viding said outer portion of said shell adjacent the conduit into upper and lower compartments, a blower ‘in the upper compartment on said plat form for forcing air into said conduit, an oil 26 burner in the lower compartment, and means pro viding an opening for the oil burner nozzle through said conduit. 2. A warm air furnace comprising a shell, a partition dividing said shell into two chambers, a fuel burning device and a‘ blower disposed in one chamber and arranged in vertically spaced relation one above the other, a cold air duct Jun teposed to said partition and leading downwardly from said blower to the lower portion of the sec pipe 3i, but to cause the some to more nearly ond chamber, a. radiator in said second chamber, follow the path indicated by the arrows on Fig. 5 -_ and means in said duct for dividing the air stream so that the gases pass around the major area and also affording connection of said fuel burn of the individual dues or tubes 23, a bailie plate ing device with the interior of said radiator. 3. Awcrm air furnace, as claimed in claim 1, 35 ~ 33, substantially triangular in shape fits in be tween the rearxnost pair of tubes es. ’ The basic wherein the opening providing means is disposed ‘ plate 33 has its lower end resting against a brack at M and isprovlded with a combined handle and reinforcing piece it on its under side. The in the conduit in such manner as to separate 40 upper end oi.’ the baille 3% bears against a bar til which is spaced a short distance beneath the top -wall of the radiator. Since the ba?le 33 is di-» rectly in front oi‘the smoke pipe 3i and comrs the space between the rearmost pair of tubes 25, 45 the gases and other products of combustion must pass upwardly over the battle plate 23 or in rear oi the upper portions of the tubes 1'5 as will read iiy be apparent. ‘ As best shown in Fig. '7, the space on each side of the *lower end or the plate 93, adjacent the lower end thereof, is closed in any suitable man; nor by s ?ller piece 31 leaving a relatively small opening 38 at each end so that soot and the like will drop through the opening 58 into the com 55 bustion chamber. In use, the chamber, divided by the baille plate 33 and the rear wail of the radiator it, may receive soot, etc. and in order the air passing therethrough into a plurality of streams. ‘ 4. A warm air furnace, as claimed in claim 1, 40 wherein the opening through the cold air conduit is bounded by inclined sides so ‘disposed as to divide the air into two streams. ' 5. A warm air furnace comprising a. shell, a partition dividing said shell into two chambers, a fuel burning device and a blower disposed in one chamber and arranged in vertically spaced ‘ relation one above the other, a platform for supporting said blower, a radiator in said second chamber. a cold air duct juxtaposed to said par 50 tition and leading from said blower to the lower end of said radiator, and means in said duct providing an opening to said radiator and sealed from the interior of said duct to enable a portion of said fuel burning device to extend into said 55 radiator. / V DALE R.
