COOKING-RANGE.

SPECIFICATION forming part of Letters Patent No. 429,546, dated J une 3, 1890. Application led August 3, 1889. Serial No. 319,624' (No model.) Patented in England November 29, 1887, No. 16,432.

To all whom it may concern.-

Be it known that I, THOMAS ROGERS, a subjectof the Queen of Great Britain, residing at 27 The Triangle, Bournemouth, in the county of Hants, England, have invented new and useful Improvements in Cooking-Ranges, (for which I have obtained a patent in Great Brit ain, No. 16,432, dated November 29, 1887,) of which the following is a specification.

This invention has for its objects to provide an improved cooking-range wherein the heat from the fire is utilized to the best advantage for heating the ovens and the boiler, to provide a novel construction of parts whereby a range of va given size can be heated with a comparatively small quantity of fuel, and to provide novel means for heating the air that supports combustion and produce a range that practically consumes the smoke.

The objects of my invention I vaccomplish by the features of construction and combination or arrangement of parts hereinafter described, and speciically set forth in the claims, reference being made to the accompanying drawings, in which- Figure 1 is a front elevation of a range elnbodying my invention. Fig. 2 is a sectional view of the same taken on the lineocx, Fig. 1. Fig. 3 is a sectional view taken on the line 'y y, Fig. 2. Fig. 4 is a vertical sectional view taken through the fire-box. Fig. 5 is a sectional view taken on the line e z, Fig. 1; and Fig. 6 is a detail view of one ofthe dampers for the ascending rear dues.

In order to enable those skilled'in the art to make anduse my invention,l lwill now describe the same in detail, referring to the drawings, Where- The numeral 1 indicates the framing of the range, and 2 the 'top plate, having` removable rings 3, as usual, for pots, kettles, and the like.

The fire-box 4, having opening and closing doors 5 and 6, is located between the two opposite or side oven-chambers 7 and 8, which are furnished, respectively, with adjustable shelves 9 and 10; and 12 indicates the ashbox. v

In the base of the range,between the ovenchamber and beneath the ash-box, is arranged a series of horizontalbaile-plates 13, provided with alternating end openings or passages,

and in the front wall of the range, beneath the lower lbaffle-plate, is placed a register or slide-door 14, of suitable construction to control the admission of the air to support combustion. The battle-plates are supported at each side edge bya vertical partition-plate 15, such partitioirplates being so arranged, respectively, as to provide an ascending flue 16 at the inner side of the oven-chamber 7 andan ascending due 17 atthe innerside of the ovenchamber 8, said dues opening at their lower ends, respectively, into horizontal rectilinear chambers 18 and 19, located between the base- Vplate ot' the range and the bottom walls of the oven-chambers. Thevertical detlecting-plates 20 and 21 are placed, respectively, in the chambers 18 and 19, their upper edges joining the bott-om walls of t-he oven-chambers and their lower edges joining the base-plate ofthe range. These deflecting-partitions are arranged diagonally and converge toward cach other from the rear vascending dues 22 and 23 toward the front wall of the range. The ascending dues 22 and 23 rise from the base of the range at the extreme'back thereof, one passing directly behind the rear wall of the oven-chamber 7 and the other behind the rear wall of the oven-chamber 8.

The dampers 24 and 25 are respectively pivoted in the rear ascending tluesbelowthe top plate 2, and are furnished with cut-away or recessed rear edges to avoid accumulation of soot thereupon, and the dampers are provided With cranks, to which are connected pull-rods 26 for swinging the dainpers so as to open or close the upward passage of the products of combustion through the rear ascending fines.

A diving side Hue 27 extends between the outer side wall of the oven-chamber 8 and the adjacent side wall of the range, and a similar diving side flue 28 extends between the outer side wall of the oven-chamber 7 and the adjacent side wall ot' the range, said diving-dues communicating respectively at their lower ends with the rectilinear chambers located beneath the oven-chambers. The upper ends of the diving-fines communicate by lateral passages with the top of the central fire-box, such passages or tlues passing, respectively, over the ovens and also over the side Water-legs 29 of a boiler 30, which at its IOO rear is suspended or hangs down to form the back of the lire-box.

The tire-box is bounded at each side and at its rear by the inner walls of the boiler, so that the lat-ter is eifectually heated, and between the outer legs 2) and the inner side walls of the oven-chambers are provided, rcspectively, the inner diving-fines 3l and 32, that permit the downward passage of some products of combustion between the waterlegs and oven-chambers.

In the rectilinear chambers in the base of the range are respectively arranged air-heating chambers and 311-, which are connected at one point with the external atmosphere by means of openings 35 and 36 in the frontwall of the range and at another point with the lower portion ot the oven-chambers, as at 37 and 38, the object being to heat the air that enters the oven-chambers. The air-heating chambers are cach composed of a series of communicating pipes or tubes, made so that the air must take a circuitous path, as indicated by the arrows 5. The top portions of the oven-chambers are provided with air-es cape orifices controlled by slide or other dainpers 39, over which are iixed hoods 40, which project over the iiues 27 and 28, the object being to deiieet the escaping hot air and vapor down into said diving side iues 27 and 28, as indicated by arrows 6. The air to support combustion enters the register or door 14, and in it: circuitous passage around the bathe-plates, as indicated by arrows 1, such air becomes highly heated by the heat radiated from the side plates l5, and in this condition such air rises between the gratebars to the lire, the object being to enable the range to consume the smoke. A flue 4:1,

ubeneath the boiler 30, conducts some heat thereunder to the chimney 42. The products of combustion rising' from the re pass laterally over the water-legs 29, some pass ing down the diving-lines 3l and 32, as indicated by the arrows 3, and some crossing over the oven-chambers and passing down the diving side tlues 27 and 2S, as indicated by arrows 2. The products of combustion pass from the diving side flues into the rectilinear base-chambers 1S and 19, and bythe partition-plates are deflected and thereby caused to pass over and heat the entire bottom walls of the oven-chambers, from whence the products enter the ascending rear iiues 22 and 23 and heat the oven-walls. The passage of the products of combustion, as explained, can be controlled by the dampers 24. and 25, as will be obvious. The products of combustion in the rectilinear base-eha1nbers heat the air in the hot- air chambers 33 and 34, so that such air in the latter enters the oven in a hot condition and passes out at the top, as indicated bythe arrows 6. While the ovens are being used the fire-box doors '5 6 are closed and the air to support combustion enters by the register or door le and orifices 43 and 44, formed, respectively, in the top of the ash-box and the framing of the range, the course et' the air entering the said orifices being indicated by the arrows 4. It the dampers 2t and 25 are open and the damper 45 of the chimney 42 is closed, the products of combustion take the course indicated by the arrows 2 to the chimney, while it' the dampers 2t and 25 be closed and the chimney-damper 45 be `opened the products ot' combustion pass by flue Lil under the boiler direct to the chimney, as indicated by the arrows 5t. It it is desired to provide a slowlyburning fire, the register or door li is closed and the air to support combustion enters solely by the orifices 43 and at.
