COOKING-RANGE.

Specification of Letters Patent No. 7,946, dated February 25, 1851 To all whom, it may concern ton, in the county of Suffolk and State of Massachusetts, have invented certain new in Cooking;

and useful Improvement Ranges; and I do hereby declare that the same are fully described and represented in i the followlng specification and accompanymg drawings, letters, figures, and references 3 thereof.

In the said a front elevation of my improved cooking range.

chamber. Fig. 10, is a top view of the connecting piece or plate by'which the water back is connected with the hot air plate, or plate which constitutes the top plate of the hot air flue. Fig. 11, is a top view of the said top plate of thesaid hot air flue.

i 12, is a front edge view of the said top plate.

F 13, is a rear edge view or elevation of the connectingpiece. Fig. 1 1 is a top view of the boiler plate, or that plate of the range which is situated directly over and parallel to the aforesaid top plate of the said hot air flue. Fig. 15 is a side elevation of the cast iron fire place frame. Fig. 16 a back elevation of the oven flue frame.

In the said drawings A represents the furnace or fire place of which E is the grate and C the ash pit, D the hot wateuback placed directly in the rear of and formlng in part the boundary of the fire place, Directly in. rear of the hot water back, is a hot air chamber E, into which the cold air isto be admitted inany convenient manner, and out of which it is to be conducted by a flue space F extending directly under the plate.

G with which the hot water back is to be connected by the. connecting piece- H to be drawing Figure 1 represents j hereinafter described. The top or upper Be it known that I, Mosns POND, of Bosmentioned. From the top surface of said connecting piece, three or any other suitable number of plates 6%, e,f, are made to extend horizontally, and to lap or rest upon the top surface of the plate G. From the under surface of the upper part of the said connecting piece, two or any other suitable number of projections 6 j, are made to extend under the plate G, the said lates or projections 6 7, being arranged before described, as projecting from the top surface of the connecting piece. Similar projections g, 72,, extend from the. upper surface of the plate G. There is also between those a similar one 2'. extended from the lower surface of saidjplate and between them on its top surface. The several projections of the top surface of the plate G where said plate is carried up against the connecting while the projection from the under side of 1 the plate G underlaps the connecting piece, the said projections of said connecting piece and plate being made so to interlock with each other as to overlap or underlap the joint or line of contact between the connectingpiece and the plate G so as to closely break or cover the said joint. 1

By inspectionof the drawings of the hot water back it will be perceived that ithas two pipes Z, m,entering one endof it, the said pipes being usually cast in one piece with the water back. i 1

Now as it is often desirable in setting up a range to be able to change or reverse the water back or to so arrange it that the pipes will pass out of it in a direction either to the right or to the left, or from one or the other endof it, I have provided the water back. with theconnecting plate and connections by which it may bereversed orturned I place.

around end for end at pleasure as circumstances may require. It might be thought that the plate Gr could be cast with an inclined fianch to rest against the beveled part of the water back and to lock under the projections of such beveled part, and thus entirely dispense with the connecting piece, and interlocking projections of it and the plate G, but were this the case, it will readily be seen that in order to remove a water back at any time for the purpose of substituting another should the first be injured by the fire, or crack by passing of the water therein, a very common occurrence, it will become necessary to move it downward and backward, and that this would involve the necessity of not only cutting away the brick work directly under it or on what it rests, as well as that in rear of its ends or against which they rest; the cutting away of such brickwork is not only extremely diflicult to be effected, but necessarily occasions a great waste of time and labor,

both in the cutting away and reparation of it.

With my improved connecting piece no depression of the water back is necessary in order to remove 1t, nor 1S necessary any cutting away or destruction of the brick work on which its bottom part rests. It may be removed forwards and horizontally and so as to carry with it the connecting piece or separate it from the plate G. Again should we dispense with the connecting piece and cast overlapping and underlapping projections on one side only of the water back, such as are cast on the connecting piece, it will be readily seen that we can only use the said water back in one direction, that is to say; that it would not be reversible as above stated. Consequently from the above it will be seen that the connesting piece becomes essential as far as convenience and a saving of labor time and expense is concerned.

In the drawing I I represents the oven as placed above and 011 the right of the fire In Fig. 14 it will be seen that the plate K which constitutes the top plate of the cast iron fire place frame I I, is made not only with a large recess Z along one edge of it, but also another and similar recess 112, along its opposite edge, each of said recesses being formed by two projections or flanches 92,0, made to extend vertically from the top surface of the plate, and par allel to one another, and at a distance apart equal to the thickness of the oven side flue plate M', the bottom of which is to be placed and made to rest on either of the said recesses according to the position in which the oven is placed, either on the right or left of the fire place. If the oven is placed on the right of the fire place, the flue plate M is so disposed on the left of the oven; if on the contrary the oven be placed on the left of the fire place, the flue plate M must be disposed on the right of the oven it being attached in any convenient manner to the oven supporting and flue frame Q. EX- tending down from both sides of the plate of the fire place frame, are two flue plates 79, 9, through the rear part of each of which a flue opening or passage 1 is made. Thus it will be seen that the fire place frame is provided with two flue openings, the object of the same being to enable the oven to be arranged on either side of or to the right hand or left of the fire place as circumstances may require.

Besides this should it be desirable, it will be seen that such applications of two recesses and two flue opening plates admit of two ovens being used in connection with the fire place, one of the said ovens being placed on the right hand of it, while the other is arranged on the left of it.

I now propose to describe the arrangement of fines by which the smoke and heat are made to circulate around the oven. After passing from thefire place and through the openings of the fire place frame, the smoke enters the flue space R situated directly under the left part of the oven, thence it passes forward and circulates around the front end of a partition plate S placed directly under the oven, thence passes backward through a flue T situated under and against the oven, and into a vertical flue U which is carried upward againstone half of the rear end of the oven, thence into a horizontal flue V carried over the surface of the oven and to the front thereof thence into another horizontal flue W, which extends rearward over the oven and from the front to the back part thereof, thence through the damper opening X and thence into the discharge pipe or chimney. Out of the flue which carries the heat around the oven, radiating spaces Y, Z, are carried in such manner as to allow the heat to circulate from the fines against the upright sides of the oven, as well as against that portion of the back of the oven, against which the flues are not .carried or against which they do not directly act, it being usually customary to leave a very narrow space between the brick work and the back plate of the oven. This space however forms no part of my invention.

The top plate of the oven frame I make with two openings X, A, which lead respectively out of the fines W, V. A cover B is fitted to one of these openings while a sliding damper C is adapted to the other. Both openings are to be made of the same size, and so that either the cover or the damper may be applied or fitted'to either of them as the case may require, each being provided with a set of parallel guides D D or E E to guide the movements of the damper when applied to it. When the oven is placed on the right side of the fire place,

the damper is applied to the opening X,

- sheet iron, and has its bottom platestiifened by a fixed plate E of cast iron, placed underneath it and riveted to it, this plate does not extend quiteto the front edge of the bot-tom plate of the oven, but is made to terminate a short distance therefrom and so as to allow the said bottom plate, when-the oven is in place to rest on the bottom of the opening of the frame or plate F.

In order tomove the oven it becomes necessary to raise it upward a little before it can be drawn out of the frame by which it issupported, so inorder to admit of its beingraised up. The partition which divides the flue V from the flue W, has a sliding plate Gr aflixed to it, by means of such contrivances as will not only hold it against the positions, but admit of its being raised or lowered or allowed to slide freely up or down, and to drop by its own weight and rest upon the top of the oven, so as to make a close joint when the oven is in place. On raising up the oven in order to remove it, the plate (G) will readily rise upward with it and admitof its being removed. It also permits the oven to be readily inserted in a place and by dropping down upon the oven 40 prevents the smoke from passing from over flue V under the partition and into the other flue W. The regular flue passages around the oven are carriedin contact with the bottom part thereof, one half or a portion of the back part thereof, and the top thereof, they in no respect are intended to lead the smoke and volatile products of com bust-ion against the sides of the oven, such side'of the oven being heated by the heat that passes from underneath the oven and into the fines or spaces which are made directly against the said sides of the oven.

What I claim as my invention is 1. The improvements by which the hotwater back is connected with the plate G and by means of which said hot water back may be either readily removed at any time, or applied in such manner that the directions ofits water pipes may be disposed so as to accommodate the bath boiler into which they are usually led, on whatever side of the range the said bath boiler may be placed. The said improvements consisting first, in the connecting piece H and the attachments of it and the hot Water back, the whole being made to. operate together, substantially in the manner as above set forth. Second, in asecond set of attachments (fixed on the opposite face of the water back) in combination with the. first set thereof, as described. i

2. I also claim the peculiar arrangement of fiues which lead the smoke and volatile ward and over and against the top of the oven and conveys it to the chimney or discharge fiue. Not meaning to include in such arrangement the radiating chamber or space Y, Z, hereinafter mentioned.

3. And I also claim the two recesses Z, m, and two flue plates, 12, 9, applied to the plate K in combination with the two valve openings X, A, thin damper and .cam plate as applied to the top plate of the oven frame and used under an. arrangement of oven flues substantially as described, the same a1- lowing of 'the adaptation of the oven to either-side of the fire place, or the use of two such ovens and their frames, in connection with the fire place, all essentially as hereinbefore stated.

4. I also claim the improvement by which the oven can be raised and readily removed, and by which the smoke is prevented from passing underneaththe partition which separates the flues. on top of theoven the same consisting in the sliding or gravitating plate G, aifixed to the partition and made to operate substantially in the manner as specified.

In testimony whereof I have hereunto set my signature,this twenty-thirdday of. September, A. D. 1850. y
