HOT-AIR FURNACE.
'srncIFIoATIoN forming part of Letters Patent No. 650,300, dated. May 22, 1900.
Application filed November 23, 1899. Serial No. 738,085. (No model.)
To a whom it may concern.-
Be it known that I, SOLOMON S. CARVALHO, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented new and useful Improvements in Pure Hot-Air Heaters or Furnaces, of which the following is a specification.
This invention consists in certain novel features of construction set forth in the followin g specification and claims and illustrated in the annexed drawings, in which-=- Figure 1 is a sectional elevation of the heater. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a section along mm, Fig. 1. Fig. 4 shows a modification.
The furnace comprises a shell (1. This shell being raised or supported on legs and having an open bottom, air can readily enter for feedin g the flames, and after said air is heated and reheated by the flames in the shell it imparts said heat to the air chamber or chambers hereinafter referred to. The device is shown of rectangular form, Fig. 2, but can of course be made of any suitable shape and material. An inlet or cold-air pipe is shown at 1 passing through the shell and leading into an airchamber 2 of enlarged capacity or cross-section as compared with inlet, 1. Chamber 2 communicates at 2 with chamber 4, which latter communicates at 4: with chamber or drum 5. From chamber 5 lead pipes 5, which conduct the hot air to the rooms or parts of the house to be warmed. The chambers are in the shell a, and heat is supplied directly to the chambers by flames or burners 3, 6, and 7. The chambers 2 and 4 being spaced or separated from the shell the heat generated by the burners or heat-supplies passes about the exterior of these chambers. Such chambers being separated from or closed airtight against the interior space of the shell the products of combustion in shell a'cannot enter the chambers.
The outlet or chimney 11 for the products of combustion is of smaller capacity than the open bottom ofshell a.
The flames or burners can be supplied with example, oil-could be used. The burners are shown suppliedby pipe 8, having the several branches for the series of burners 3, 6, and 7. Each series can thus be turned on or off and the heat supply thus graded or regulated. Each burner of a series is also shown with its individual stop-cock, so that one or more burners of a series can be opened or shut, as required. The branch pipes for series 6 and 7 are shown extending through chamber parts 2 and 4:; but said pipes can be led about the outside of these chambers, if preferred.
To prevent the flames from burning through a chamber-bottom a plate or chamber-bottom protector 9 can be employed. This pro tector 9 is shown slidable into the brackets or flanges 10 and can be readily removed or replaced. A protector can be applied to one or more of the chambers, as required.
The air-tight heating- chambers 2, 4, and 5 having the flames applied directly thereto there is created an induced draft by which air is violently drawn from inlet 1 into such chambers, the heat from said flames also warming the air in the chambers. After the air has been finally conducted to chamber 5 it is used for warming purposes.
The shell (1, can have a door allowing access to the interior of the shell or to the burners and chamber-walls.
By providing outlet 11 with a damper the draft through said outlet can be regulated as required, thereby regulating the superheating of the chambers in shell a.
Each outlet-pipe 5, as seen in Fig. 4, can have a heating-box 5 of enlarged capacity as compared with this outlet 5. Ashell a about and spaced from the box 5 has a heat-supply 3 for the box 5". The pipe 11 carries the products of combustion from shell c. The shell of has an open bottom of larger area than outlet 11, and the box 5 is closed against the interior of shell (1', so that products of combustion cannot enter from the burner 3 into the box 5". The individual heat-supplies 3 for each box 5 can be used simultaneously with the heat-supplies in shell a, or either the heat-supply in shell a or in shell a can be used by itself.
What I claim as new, and desire to secure by Letters Patent, is-
1. A heater or furnace comprising a single outer shell having an inlet or open bottom, the mouth or opening of such bottom being pacity as compared withthe inlet, and a heatsupply applied directly to the chambers, said chambers being spaced or separated from the 1 shell and closed againstthe interior space of said shell, andoutlets 5 from said vacuum chambers, each outlet havinga heating-box 5" of enlarged capacity as compared with the outlet, with an individual heat-supply for each heat-box, and ashell a about and spaced from said heating-box and having an open bottom and contracted outlet 11', said heating-box 5 beingclosed against the interior of the shella substan tially as and for the pu rpose described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing {witnesses S'OLOMON 8. OARV ALHO.
