ALLEN GARDINER INGALLS, OF LAPRAIRIE, QUEBEC, CANADA.

FURNACE.

To all whom it may concern.'

Be it known that I, ALLEN Gannixnn xoaLLs, a subject of the King of Great Britain, residing at the town of Laprairie, in the county of Laprairie, in the lrovince of Quebec, in the Bominion of Canada, have invented certain new and useful improvements in Furnaces, of which the following is a specification.

rilhis invention relates to improvements in furnaces, as described in the present specification and illustrated by the accompanying drawings that form part of the same.

rlie invention consists essentially of the novel construct-ion and arrangement of parts, whereby7 the circulating water is heated between outer and inner shells and the fire supported on a close tire pau at the bottom of said inner shell.

The objects of the invention to apply a simple and known forni of tire box to a hot water heat-ing apparatus, to simplify and thus lessen the cost of hot water furnaces, and to devise a type of furnace in which sure combustion is assured and consequently economy in the consumption of fuel effected.

ln the drawings, Figure l is a perspective view of the furnace complete. Fig. 2 is a vertical section of the furnace. Fig. 3 is a perspective view of the inner casing showing the fire box and tine. l? ig. i is a cross sectional view through the line rfa-B, in Fig. 2. Fig. 5 is a sectional detail of a portion of the furnace casing showing the feed opening and door in its open position.

Referring to the drawings, L is a base of inrerted pan shape having the pipe openings l and c through the top thereof to the rear of the portion l5, the latter forming the bed of the tire box or otherwise a close fire pan, the expression said close tire pan 7 conveying the meaning of a fuel support without draft openings therethrough. e and f are openings through the side wall of said base. ttl are bolt holes through the top of said base in proximity to said side wall.

'f/ is the inner shell of the furnace, the front wall 7i. of which forms the front wall of the tire box j, while the rear and side wall 1'. of said fire box is formed by an extension rearwardlyY from said front wall 7L joining the reverberatory flue 1 toward the top end of said tire box j, the said .everberatory flue con- Speecaton of Letters Patent.

i latter registering with the opening c in the main base a. The reverberatory tine le continues upwardly and extends along over and forms the top of the fire box the egress opening Z from said tine being through the upper end of the front wall 71, of said inner shell. m is the feed opening to said fire box through said front wall 7i immediately below the opening Z. n is an opening at the lower end of said wall 7i. forming the damper opening and also an opening for the removal of the ashes in the lower end of the tire box. The walls /z and i, as also the lower end of the reverberatory tine, rest on the said base o and preferably in construction form part therewith, the said walls lz, and e' terminating at the edge of an opening 22 corresponding in size to the lire pan it, though it must be understood that this base can be completely closed in and form a lire pan in itself in place of building the tire on the main base u. u are bolt holes adjacent to the edge of the base o and registering with bolt holes -tt through the main base o on which the said base o is supported. t the upper end of the said reverberatory Hue .7.; and at the beginning of that portion thereof, where the said flue 7a extends 'over the tire box. a suitable opening therefrom leads to the pipe "n closed by the cap ll. yze is an opening into said tlue at the top end of said tire box j, a seat a; being formed around the said opening to. The bases a and o are securely bolted together through the bolt holes 4:6 and n, as explained hereinafter, so that the tire box is thus made complete with the exception of the necessary doors and dampers, the passage for the hot gases being over the top of the wall yz'y into said reverberatory flue L' and ou through said flue over the top of said tire box out through the opening Z into the chimney 13. y is a pipe extending through the opening o in the wall of the main base a under the tire box and leading to the open` ings r] and fr, the said pipe being for the purpose of inserting a cleaning instrument for clearing out the lower end of said flue. is a cap closing the outer end of said pipe y. Q is the outer shelll preferably domeof the link 2st and to the lug 22.

-rounding the saine.

shaped and havii'ig the vertical reii'iforeing ribs S terminating at their lower ends in the flange 4. 4B are bolt holes through the said flange et registering with the bolt holes elo, the said flange el of the outer shell 2 resting on the base 0 of the said inner shell, and the three, that is to say, the outer shell 2 through its flange t, the base o and the main base t being securely fixed together by the bolts 5 extending' through said bolt holes.

It has already been stated that the main base and the base 0 are secured together by bolts, but it must be understood that in this construction the three parts are all secured by bolts.

The outer shell 2 has an opening' at the front thereof corresponding to the shape of the front wall It of the inner casing and sur- G isa panel closing the front opening to said outer shell and securing said outer shell and said inner shell together by means of the bolts T extending through said panel (i into and through the wall /t of the said inner shell. The panel 6 has openings corresponding to the openings in the wall L, the opening 12 registering with the flue opening Z, the pipe 13 extending therefrom, and the opening 14 registering with the feed opening m. Again said outer shell has an opening' 9 through which the pipe 11 from the inner shell extends, the gland 1() being formed around the junction of the said pipe o and the said outer shell.

15 is a door frame extending inwardly through the feed openings 1a and m and having the sides 17 receding from their lower ends, said walls forming the inwardly projecting shoulders 18 beyond the inner face of the wall L. rl`he base 16 of the door frame 15 slants downwardly and is secured to the panel G by means of the bolts 2O inserted through the i'iange 19, the latter extending downwardly from said door frame base. 21 is a door hinged to the outer edge of the base 1G of said door frame and having the lug 22 projecting from its outer surface and an orifice 23. 2st is a link pivotally secured to the lug 25 projecting outwardly from the flange 1S). 26 is a rod curved at its lower end and pivotally secured at the lower end 27 is the door handle having its shank 28 extending inwardly therefrom through the said orifice 23.

2S) is a cam tixedly secured to the inner end of the shank 28.

30 is a plate forming a damper hinged to the outwardly projecting part 31 of the iiange 32, the latter extending upwardly from the door frame 15 and the said plate or damper 30 resting in its lower position on the shoulders 18 forming part of the door frame.

The door in its open position rests on the rod 26, the link 24 turning to its lower positon'.- Un the closing of the door 21 the link rises to its upper position beneath the base 16 and a curved portion of the rod 26 extends around the hinge of the door. On the action of closing the door, the handle 27 is turned in order to lock it to its closed position and as the said handle is turned, the cam 29 engages the lower face of the plate or damper 30 and raises said plate or damper 30 into engagement with the seat fr, thus closing the opening w.

33 is a door frame of somewhat similar construction to the door frame 15 with the exception that the base 3% preferably extends in a straight line outwardly from the interior inner surface of the lire box and is supported by the pieces 35. The sides of said door frame are joined at the top Vby the piece 3T, from which the iiange 38 extends upwardly and is secured to the panel 6.

39 is a door hinged at the outer edge of the top piece 37 and having a suitable handle 40 attached to the lower edge so that the said door may be raised for the purpose of ncreasing the dra-ft and removing ashes from the tire pan.

Il1 is a pipe extending through the opening in the side wall of the base and suitably elbowed and connected to the pipe t at its inner end and at its outer end to a suitable water supply, the pipe t leading under said base to an opening s into the water chamber formed between said inner and l outer shell and surrounding said lire box and iue.

50 is an outlet opening from the outer shell 2. 42 is a pipe leading from said outlet opening to the heating pipes.

The use of this device will be readily understood from the description of the part-s, as the water entering through the inlet opening' s lls the space between the inner and outer shells, and then circulates throughout said space and the heating pipes.

This invention is the adaptation of an old form of heater to a hot water heating furnace construction and though in some parts of the country, said old form of heater is largely used and appreciated, its application to a modern method of heating houses and buildings has not been made hitherto. InA this form of heater, i'ire is built on, what may be termed, the ground, though this may be more clearly explained by saying that it is built on a close fire pan a bottom to the fire box without draft openings therethrough. The fire box in itself is preferably in av form of tube, in which fuel is fed on top of the fire burning in the bottom of said box and the ashes simply removed from the fire box itself at a lower door.

In this form of furnace there is quite a hea-ting surface and this heating surface is added to by the reverberatory flue, though the said rei-'erberatory Hue is not actually necessary to the invention, though it is preferably included in the construction.
