WATER-BACK GAS COOKING-STOVE.

SPECIFICATION forming part of Letters Patent No. 449,179, dated March 31, 1891,

Application filed May '7, 1890. Serial No.350,888- (N model.)

To all whom it may concern.-

Be it known that I, HENRY R-UPPEL, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Water-Back Gas Cooking Stoves; and I do hereby declare that the following is a full, clear, and complete description thereof.

My invention relates to a gas or vapor cooking-stove so constructed that cold water from a tank is carried through pipes around the several burners of said stove and back into the tank heated, said stove being so constructed and arranged that the heating of the water will not interfere with cooking over one or all of the burners at the same time.

That the invention may be seen and fully understood by others, reference may be had to the following specification and annexed drawings, forming part thereof, in which- Figure 1 is a plan view of one of the front burners with a section of the water-pipe in position, and Fig. 2 is a side view of same.

Fig. 3 is a plan view of one of the burners without the pipe. Fig. 4 is avertical section of one of the burners without the water pipe, showing the spreader in the center thereof. Fig. 5 is a reduced plan view of four burners of a gas cooking-stove with water-heaters and connecting-pipes. Fig. 6 represents a section of the stove and tank in perspective. Figs. 7 and 8 are detail drawings of parts used and hereinafter fully explained.

Like letters of reference designate like parts in the drawings and specification.

Circumscribing each burneris a hollow pipe A, Figs. 1,.2, and 5, preferably of circular ring form, the depression a, Figs. 3 and 4,

forming a bed for said hollow rings. On the outer side of the burner, outside said depression a, is a series of holes for jets b passing entirely around said burner. On the inside of the burner and extending all the way 5 around is another series of holes for jets c.

A cross-piece cl, Fig. 4, is secured on the illside of the burner, into which is threaded the spreader 13, Figs. 1, 3, 4, and 5.

As shown in Fig. 5, the tubular rings A are connected with each other by the pipes e, f, and 9, so that cold water coming from the tank through the pipe 7L will pass around the first burner on both sides, as shown by arrows, and then proceed through the pipe 6, around both sides of the second burner into the pipe f, around the third burner into pipe g, from thence around the fourth burner and out the pipe t' heated. The spreader can be adjusted so as to be level with, below, or above the top of the tubular ring A, the air coming through the open space in the center of the burner and coming in contact with the spreader forces the gas from the jets 0 against the inner side of the tubular ring A.

The two sets of jets b and c are separated from each other by the tubular rings A. Therefore to facilitate the lighting of the burners four grooves j" and 7a is, Fig. 3, are cut from the holes 1) to the holes 0, said grooves being perforated, as shown in Fig. 3. When the outer jets b are lighted, the flame is communicated to the inner holes 0 by means of these grooves jj 7.; 71).

Bolted to the induction-pipe C at its mouth is an air-inlet D, Figs. 1 and 2. are detail views of said air-inlet, which is constructed as follows:

The part shown in Fig. 8 is rigidly attached to the induction-pipe by means of the bolts Z and m, Fig. 2, and is of the shape shown in the drawings, having one or more slits or openings (three being preferable) therein, and a hole in the center, through which the gas enters the induction-pipe. A sleeve of similar shape (shown in Fig. 7) fits loosely on the part 8 5 shown in Fig. 8. The sleeve has slits or openings n n n therein corresponding with the openings 0 0' 0 of Fig.8. It willbe seen that the amount of air can be regulated by turning the sleeve E, Fig. 7. The air-inlet being curved, as shown in the drawings, causes the air entering the slits in said inlet to enter in an angular direction. The three currents coming together and combining with the gas 'directlyinfrontof the induction-holes thereby causes a strong current through the several induction-pipes to the different burners. A nut G, Figs. 1 and 2, may be tightened against the end of the sleeve E, thereby holding said sleeve in position when rightly adjusted.

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

Figs. 7 and S 7 I 1. In combination, a burner having an inner and an outer row of jets and formed with a seat between said jets, and a water-pipe resting upon said burneron the seat between the jets, substantially as described.

2. In combination, a burner having an in ner and an outer row of jets, a central spreader acting upon the inner row of jets for deflecting the same outward, and a water-pipe extending about the burner and in position to be struck by the deflected flame from the inner jets and the flame from the outer row of jets, substantially as described.

- 3. In combination with a burner having a depression a with jets on each side of the same, the water-pipe resting in said depression against the burner, substantially as described.

4. In combination with a burner having an inner and an outer row of jets, the water-pipe extending between the jets, the said burner having grooves extending beneath the waterpipes from the inner to the outer row of jets, said grooves having perforations substantially as described.

In testimony whereof I afflx my signature in presence of two Witnesses.

HENRY RUPPEL.
