CONVERTIBLE BUILT-INvI-IOT-AIR FURNACE.
Application filed January 25, 1924. Serial No. 688,474.
This invention relates to furnaces of the type where the actual combustion takes place in or near the room to be heated. While the furnace is illustrated as being near the room to be heated and such is the preferred loca tion sight must not be lost of the fact that due to the more perfect circulation obtained, one or several:roomssomewhat removed from the location of the furnace may be heated by the device with perfect satisfaction. The primary object of the present invention con- .si-sts in-the provision of a convertible builtin hot air furnace which can be used as an open grate or by the addition of a one-piece front can be used as anordinary hot air furnace. :Other objects of the present invention relatelto the specific \details of construction and various combinations of the parts of the furnace as called for in the claims.
In the drawings,-
Fig. 1 is :a front elevation of a structure wherein the of a furnace.
Fig. 2 is a front elevation with the structure converted into an open grate.
Fig. 3 is a view similar to Fig. 2 but showing the device in use as a :grate.
Fig. 4 is a horizontal section through the air passage in the heating chamber.
Fig. 5 is a vertical section through the g. 6 is an elevation of the s lotteddamper control disk. 7
The furnace as will be seen from Figs. 1 and :2 does not differ materially in general appearance from well. known types, having a cast .metal sectional front, the upper section 10 of which is removably secured to the furnace frame 11 by any desired quick detachable means such for example as the looking pins 12. The usual hinged fuel door 13 is centrally positioned on the furnace front preferably just below the hot blast draft 1 1 which leads to a hot blast pipe .15. ofthe usual and well known type having for its purpose the delivery of the air over the fire which is built on the grate v16. f
Just below the removable upper section front 10 there is a permanent front section 'or bottom draft plate having'at either side I bottom drafts 17 and in the center a slot 18 for access to the handle 19 of the grate cleaner :20. A pair of ash drop doors 21 is parts are assembled in the form provided beneath the grate, these doors controlling the passageway to anash pit 22, the clean-out door 23 of which is preferably to the rear as shown, there being a solid wall 24 between the ash pit and the rotatable dampers 25 which cont-r01 the passage of air through the pipes .27 and 28, these pipes leading the cold air around the fire box to the heating chamber 30. The dampers 25 are located at the lower end of pipes 27 as shown in Fig. 2.
In the drawings, 1 have illustrated the pipes 27 and 28 as being at the back and sides of the combustion chamber, but I may omit either the side pipes or the back pi e under certain circumstances. The side pipes are numbered 28. in the drawings, and the back pipe 27, which is preferably a large casting may extend over the entire back of the combustion chamber in which case it will have plurality ofrounded inwardly directed projections 32 to increase the heated area of the air passage. The side pipes'28 are placed one on either side of the combustion chamber and each discharges against a small central vertical baffle 33 in the center .of the heating chamber 30. The horizontal floor 34: preferably is open at its back or rear as at 35 so that the cold air led up through the pipes 28 must move downwardly at the rear of the heating chamber 30 passing through the opening 35 and into the portion 37 leading at the front to the vertical hot air passage 88 which in turn merges into the diagonal passageway 39 and the tortuous passageway 40 formed by the baffles 41 on alternate walls of the flue 42. The passageway 38 is integral with the walls of heating chamber 30 whereas the passageways 39 and 40 as well as the horizontal passageway l i are formed of the bricks of the chimney and consequently are well insulated by any of the compounds in general use. The wall radiator 45 maybe of the usual type and is preferably rather highup in the room as this is found to give the best diftusion of the warm air.
The dampers 25 which consist of ported plates adapted to be rotated with respect to one another to open or close the ports, are controlled from the panel 51 by means of the handle 52 which carries a sprocket wheel .53
over which runs a chain 54: passing through pipes 55 to the sprocket wheel 56 on the right hand damper 25 and by a second sprocket chain 58 to the sprocket wheel of the left hand damper 25. On the opposite side of the furnace front is a panel 60 similar to the panel 51, for the sake of symmetry the handle 61 of which is secured to the front of the water pan box or chamber 63, allowing access to the water. pan 64: which is preferably arranged so as to project somewhat into the passageways 28.
The damper 7 0 is hinged as at 71 and carries a bail 72 which is engaged by the slot 78 of the disk or operating plate 74: carried by the rod 75 which also carries the operating handle 76 preferably placed just below the mantel 77. As will be seen from Fig. 6 the slot 7 3 in the damper operating plate is in the form of a spiral so that very close adjustment of the damper 70 may be had. The grate front 7 8 is deta'chably secured to the frame in the same manner as the furnace front.
What I claim is:
