FURNACE OR HEATER.

SPEGIFIGATION forming paart of Letters Patent N0. 616,844, dated. December 27, 1898.

Applicaoion filed August 26, 1898. Serial N0. 689,605. (N model.)

T0 all whom z't mag concern:

Beit known thao I, CHARLES D. HOWARD, a citizen of the United States, residing ab Symeuse, in the eounty 0f Onondaga and State of New York, have invented ceroain new and useful Improvements in Furnaees or Heaters and I do hereby decleue the following 110 be a f all, clear, and exaet description of the invention, such aus will enable others skilled in tzhe art to whieh it appertains t0 make ancl use the same.

M'y invention relates 130 that dass 0f beating-furnaoes in which eibher hot air or bot water, 01 both, may be employed as the heata-.

ing medium; and in consists generally in the construcon and novel armngemenn and combllll0ll of the various pambs, as Will be hereinafter more fullydescribecl, and pointed 01111 in the claims. 1

The primary object of the inventiou is to produee a furnace 01 he ater which Will furnish a maximun1 amount 013 heat for the expenditme 0f a minimurn amount 0f fueL Anoher object of the invention is 110 so 0011- struet the furnace 01 heaber filmt it; may be readily adapted for hot-air 01 hot-water beating 01 a combination 0f both hol; air and hol; waner.

These and other objeets may be attained by means of the device illustrated in the aecompanying clrawings, in .which- Figure 1 represents a longitudinal vertaical section 0f my improved furnace; Fig. 2, a transverse verticalseetion of Ehe sztme, and Fig. 3 a horizontal secion on line 3 3 0f Fig. 1 With the grate rernoved.

Referring t0 the several views, the numeral lindicates the fire-pofu, whieh is provided with a, suitable graute and shaking attaehments. Below the fire-pot, suitably arranged and supported, is a removable ash-pit 2, open ab 'lS freut end to correspond. with the opening in the front Wall 3 of thefurnace or heater, so as to provide f0r the ready removal of the ashes.

Surrounding and supporting the fire -pot and ash-pit is a shell 4, approxirnately oval in eross-section, having a corrugated 01' fluted peripheral surface for the purpose of inereasing its heat-giving capaeity. The rear end of the shell is prefembly convex ancl is provided with 3 smokeexit 5, while the freut encl is open and is seourely a-ttaehed byits end 001- rugation to the front Wall of the furnace 01 heafner, as shown ab a, Figs. 1 and 3. The outer side Walls 01: the fire-pot are formed with vertical ribs 6, which fit snugly against the inner convex portions of the corruga ted surfaee of the Shell 4, and as the sides of the ash-pit conform 130 the eurvature of said inner conv6x portions of the eorrugated surface continuous flues 7 are formed between Ehe inner side walls of the sl1ell and nhe outer side Walls of t-he fire-pot and ash-pit, the diameter 0f the upper portion 01": said flues being increased by the ribs 6 0f the fire-pot, through which flues the products 0f combusoion pass Clown through flues 7 beneatl1 'ohe ash-pit and laben up into tshe chamber 8, whioh is formed. between the inner rear Wall 0f said she1l and tl1e oute1 rear Walls of the fire-box and ashpit, and thence 130 the exit 5, as shown in Fig. 1.

The nu meral 9 indicates the base 0f Ehe furnace 01 heater, in which base tl1e front: Wall 3 is tightly and seeurely seaced and from which tl1e rear end of the Shell 4 is rigidly supported by a brace 10, T-shaped in erosssection. The shell 4, With its contained firep ot and ash-pit, is inclosed by an air and Walter t-ight double-wall casing 11, whieh is tightly seated in the Oase 9 and attached at ibs fron 130 the fronta Wall of the furnaee o1 heater. The rear end of the easing is provicled with an opening 12 opposite Lhe exit1 5 0f the shell 4, through Which projects a 001- lar 13, secured 130 said shell and surrounding said exit. 'lhe space between 'he casing and shell forms a chamber 14, which may be either f0r hot air 01' hob walzen WVhen employecl as a hot-air chamber, the casing is provided with a proper exit, as shown ab 14 Fig. 1. If hob water is to be the heating medium, the easing is provided with lshe usual connections, to whicl1 the supply and reourn pipes are counected.

The front Wall 3 is provided with the usual clmft-regulating doors 13 and 14' and fuelfeeding door 15, and nhe fire*pot is provided -With a damper 16, which when open gives a l1eater, just above the g1ate, is a reetangularsheped concluit 17, having an opening in its bottom closed by e check-damper 18, which is operatecl by e rooker-arm 19. The eonduit- 17 is open et boch ends and receives eir from the ash-pit. 'lo eheek combustion, the damper 18 is opened, and to inorease oombustion the dampe1 is closed. It Will be apparent that this ooncluit also serves es a clust-fiue when the grate is being shaken, es loy open- :ing the demper the arising dust Will be earried into seid concluit, and thus be prevented from ooming out into the room 01 apartment.

The operation of my improved furnace 01 heater Will be reaclily understyood from the foregoing clescription, it only being necessary to stete thet the ei1* 01 weiser in ehamber 14 is quiokly heated to a high temperature by reason of the pecnlierly construetecl and erranged shell, whieh holds the produots 0f oombustion while they are being direete down th1ough the fiues 7, under 1;he ash-pit, and on1; into the chamber 8 to 1:he sxnokesteok.

In providing a heeting 1nedium of hol; ai1 and hob water the fire-pot may be made 1101- 10W and provided with suitable eonnections for ettachrnent 150 a sonrce of supply encl with radiator supply and 1eturn conneotions.

Various modifications o'f my invention 1nay be. maclesuch for instance, es construeting the Shell in two parts and bolting then1 130- gethe1, es shown in Fig. 2withont departing from its spirit or sacrifioing the prineiple thereof.

Having thus fully desoribed my invention, what I claim, and clesire to seonre by Letters Patent, is

l. In a furnaoe 01 heater, the oombinauion with the freut thereof, of a Shell heving a 001- rugated peripheral surface ancl e plain back, a fire-pot and ash-pib supported within the shell and so erranged that oontinuous hob-eh flnes are formed vertieally along the sicles of the firepot ancl ash-pit, substantially es specifiecl.
