IMPROVEMENT IN COOKING RANGl-IS,`

To ALL WHoM 1T MAY ooNonRN;

Be it known that I, MAURICE C. H L'LL, of the-city and State oi'rNew York, have invented, made, and applied to use, a certain new and useful Improvement in Cooking'vRanges; and I do hereby declare the follow` ing to be a full, clear, and exact descriptionv of the saidinpention, reference being had to the annexed drawings, making pgn-t of this specification, wherein--- -i Figure 1 is vertical longitudinal-section. i i l Figures 2 and 3 are vertical transverse sections vat the lines and g/ y, respectively.

Figure 4 is a sectional plan at the line e e; and

Figure 5 is a sectional ,plan at the line 'w 'un Similar marks of reference denote the same parts.

The object ot' my invention is to obtain a range having an elevated oven that will also heat a current of air circulating through the range, and around the fre-pot and ash-pit, and thence passing through an air tube to heat any chamber or rooin. In VLetters Patent granted to me November 14, 1865, a cooking range is shown having a hot-air space around the fire-pot, but with this rangethere is not. an elevated oven. My said invention relates to a range or stove having an elevated oven, and consists in descending smoke iiues in themain portion of the range for heating a space through which the atmosphere circulates and is heated, in combination with ascending ilues and an elevated oven. And I also arrange the fines so that the heat may act more `uniformly upon ,the elevated oven. By this construction I amable to employ the range partially or wholly for heatingthe room or rooms, for cooking, or for baking.

In the drawing, a a are the side plates,b the back plate, c the front plate of a range or cooking stove, that may be set in brick-work or not, as desired; d is the grate in the fire-pot e f is the ashipit; ,q the water-back,

to which water is supplied as usual. by pipes, so as to heat the water in an adjacent 'boiler'. The upper portion of the re-pot c is formed as a groove, 1aronnd below the water-back g, opening to holes through the front `plate c ofthe range, and notches or openings are provided at the inner edges of this groove, so that the 'air passing in may enter the ireat or near its surface, and promote a more perfect combustion of the gases evolved from the fuel. The top plate 7L of the range is formed with the usual openings for receiving cooking utensils, and the plate L, that is at theV level of the top of the fire-prot, extends to the descending plates c c, so that the products of conibustion pass down the ilues'z 1', (between 7c and an) thence into the iiue I, below the .plate Z1, and up the iiue pipes m m, as indicated by the red arrows, to the flues n '11, communicating with the elevated oven;

` or, if a direct draught is required, it may be obtained by drawing the dampers n* nl inthe division between the top plate t and plate h1. The supply of atmosphere to be heated passes in through an openingat b1 4in the back plate c, into .the space c2, thence passes forward and in contact with the casing of the ash-pit and beneath the plate cl, thence rises through the opening left between the edge of cl and the front plate c, (see iig. 4,) into the space c3, and returns towards the backof the range in contact with the tire-pot, and rises to the iiues o and o to the box containing the elevated even or ovens. p is the case of the elevated ovens g q, there being spaces i all around the `ovens q, between them and the ease p. The hot-air iiues 01 open into a space, r, between the ovens q g, and the air 4passes also at the back of them, (see igs. 3 and 5 g) the plates i" and r2 being provided, separate the hot-air and smoke spaces. s s are the pipes for heated air leading to the room above. Theblue arrows indicate thc direction of the heated air. The smoke ilues 1t may be fitted with dampers, 8, and said iiue n opens into the spaces sl below the ovens g, and the products of combustion pass oit through the fines 4; at the sides,nnd 5 nt the top of the ovens, and thence by the pipe 6 to the chimney. I provide a slide or damper, t, through which steam and fumes from the cooking are allowed to pass to the pipe tl, and so escape to the chimney. I provide a flue, u, and damper, allowing the dust that may be in the air of the ash-pit, when the tire is raked, to pass to the tue Z, and not come out into the room. The ii'ues m m might be placed centrally of the range and the hot-air iiues ol, and smoke tlues 11 n be transposed in their position if desired, and eachi descending Huez' may be separated by vertical partitions, or bc formed of several descending fines or pipes either at the' sides or back of the range. I introduce a shallow vessel, 9, for water, behind the dues n and Q,

and provide a vapor-tube, 1.0, opening into the air space 1*, and a movable cap, Il, to allow the vessel to be illed with facility. The vapors mingle with the air and lnoisten it.

What I claim, and desire to secure by Letters Patent, is

1. The descending flue or fines z' z','in combination with the nir-heating spa-ces ci and c, and flues fm, passing to an elevated oven, substantially a-s specified. v v

2. I claim the arrangement of the lues z'z', Z, and m, for the products of combustin, in combinationr with the air-heating spaces c2 and c3, :ind-cir fines 0 ol, as and for the purposes specified.

3. `I claim ythe arrangement of the nir fines r s, and smokeflnes s, 4, and 5, in combination with the elevated oven q, substantially as specified.

4. I claim the escape-damper t, and pipe t, for the fumes from cooking, in combination with the elevatedl oven g, as set forth. l v

5. I claim the water vessel 9, fitted es specified in combination with the air spaces n 'n and ol, and elevated oven range, as set forth. l Y

6. I claim a. recess or groove between the water-beck and fire-pot, with openings to supply air to the re, as and for the purposes specified.

In' Witness whereof I llave hereunto set my sig-nature this seventeenth day of December, A. D. 1:866.
