WATER-H EATER.

SPECIFICATION forming part of Letters Patent N 0. 554,371, dated February 1 1, 1896.

- Application filed May 31,1895. $erial No. 551,126. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN O. NOBLE, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in ater-Heaters, of which the following is a specification.

This invention pertains to improvements in that class of water-heating devices known as instantaneous water heaters, in which class of devices a stream of water flows through the apparatus no faster than it can be heated by means of a gas-burner.

My invention will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a perspective vertical section of an instantaneous water-heater exemplifying myimprovements; and Fig. 2, a vertical section on a reduced scale,the base being omitted.

The plane of section in the two views is identical, and Fig. 2 is presented to make clearer certain angles of slope liable to aberration in a perspective view.

In the drawings, 1 indicates a rectangular box-like metallic casing or shell; 2, a removable cover thereon; 3, a base-tank in which the shell sets; 4, an inwall to the base-tank, forming an open center to the tank surrounded by a channel-shaped tank portion; 5, this channel-shaped tank open at the top and extending entirely around the tank, the foot of theshell setting in this tank; 6, a shelf near the top of the shell extending from side to side of the shell and from the rear wall toward but not to the front wall, this shelf being watertight and sloping upwardly from rear to front; 7, a second similar lower shelf; 8, a third similar still lower shelf; 9, a similar shelf between shelves 6 and '7 but projecting and sloping in the opposite directionthat is to say, with its crest toward the rear wall of the shell; 10, a lower shelf corresponding with shelf 9 and disposed between shelves '7 and 8; 11, reticulated or perforated aprons extending from the crests of the shelves downwardly to or near tothe shelf immediately below, these aprons projecting outwardly at their bases so as to produce a facial batter; 12, the lowermost one of these aprons, its lower edge extending over a portion of the channel-shaped tank in the base of the structure; 13, a water-leg formed around the lower portion of the shell where the shell sets into the base, this water-leg surrounding shelf 8 14, a gas-burner disposed within the central opening of the base and having any usual or suitable form; 15, louver-work below apron 12; 16, inlet-pipe from any suitable source to deliver water within the shell upon shelf 6; 17, outlet-pipe from base-tank 5, and 18 a hopper-shaped funnel above shelf 6, having a small discharge-opening.

Normally water stands upon the sloping shelves and in the water-leg, as indicated in Fig. 2, and water also stands in the base-tank to the height of the outlet-pipe 17. When the device is not in use the inlet 16 will be closed. To use the apparatus the gas will be lighted, the hot products from the burner then passing upwardly through the louverwork. and in a zigzag course through the aprons and between the shelves, resulting in the heating of the water which stands on the shelves and also the water in the water-leg, and also the metal of the interior parts of the structure. When the apparatus is thus heated the inlet-pipe is to be opened gently.

NVater then flows to the top shelf, the overflow therefrom going to the first apron and then down to the second shelf, and so on till it reaches the tank out of which it flows by the outlet-pipe. The inflow is to be so regulated that the water will pass through the apparatus no faster than it will be heated. The water flowing through the apparatus virtually trickles through the general ascending column of hot products from the burner, the aprons causing a practically perfect presentation of water in small masses to the hot gases. The louver-work 15 carries drip from below apron 12 into the tank. The water earliest drawn from the apparatus may be at full heat, for When cold water is admitted it simply displaces water previously on the shelves and heated. There will be some circulation and ebullition in the water-leg, the hotter water rising therefrom and overflowing from the shelf into the tank.

In some cases it may be desirable to reheat water which has passed through the apparatus, in which case top 2 is to be removed and the Water is to be poured into hopper 18, as by means of a cup, and the small-discharge-opening in hopper 18 will prevent the flooding of the apparatus, the hopper 18 forming an. emergency-reservoir to hold and discharge one pouring while another cupful is being collected from outlet 17.

I claim as my invention 1. In a water-heater, the combination, substantially as set forth, of a shell, an inner water-leg wall in the base thereof, a sloping shelf joining said Wall and forming a roof to the chamber surrounded by the water-leg, a series of sloping shelves in the shell above said water-leg,'all said sloping shelves being water-tight at three edges and open at their crests, a gas-burner within said chamber, and an inlet and outlet for water.

2. In a water-heater, the combination, substantiallyas set forth, of a shell, a vertical series of shelves therein and attached watertight to three walls thereof and sloping upwardly toward their free edges and having their free edges presenting oppositely in alternation, a heater, as a gas-burner, below the lowermost shelf, a water-inlet over the topmost shelf, and a water-outlet below the lowermost shelf.

3. In a water-heater, the combination, substantially as set forth, of a shell, a vertical series of shelves therein sloping upwardly toward their free edges and with their free edges presenting oppositely in alternation, reticulated or perforated aprons projecting downwardly and outwardly from the free edges of the shelves, a heating device, as a gas-burner, below the lowermost shelf, awater-inlet above the topmost shelf, and a water-outlet below the lowermost shelf.
