ALBERT F. TRAGESER, OF NEW YORK, N. Y.

WATER-HEATER.

SPECIFCATION forming part of Letters Patent No. 584,276, dated June 8, 1897. Application filed October 20, 1896. vSerial No. 609,443. (No model.)

To all whom, it may concern:

Beit known that I, ALBERT FERDINAND TRAGESER, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Tater-Heaters, of which the following is a specification.

My invention consists of a water-heater designed to be operated by the ordinary domestic servant to furnish a continuous supply of hot water as long as may be desired and to be used and disused at a moments notice. It is primarily designed for-domestic use in flats and the like, or wherever permanent water-heating devicessuch as the water-back and the hot-water boiler ofthe ordinary cooking-range-are either permanently or for any reason temporarily unavailable. While devices for this purpose are already known, they are complex, cumbersome, and expensive and -not very efficient, considering their bulk, rst cost, and cost of operation. My device, on the contrary, is, comparatively speaking, small, simple, cheap to make and cheap to use, and very efficient.

In experimental practice my device, when measuring but twentypne inches long by seven inches wide by twelve inches high on the outside, has raised continuously one and one-half gallons of water perminute from O up to 14()o Fahrenheit.

My device has the further superiority that it absolutely drains itself when disused, so that no stagnant water remains therein.

In the drawings forming part of this specification, Figure l represents a top plan view. Fig. lfL is a fragmentary top view showing the handle of the main gas-valve. Fig. 2 represents a side elevation, partly in section, on the line 2 2 of Fig. l. Fig. 3 is an elevation of the inlet end of my device. Fig. 4 is an elevation of the opposite end. Figs. 5 and 6 are plan views of the shelves within my device over which the water flows while being heated.

In the drawings, A represents an outer casing for ornamental purposes, inclosing most of the operative parts of my device.

B is the shell of my water-heater, provided with an exit C at top for the escape of air and spent gas.

heating in the direction indicated by the ary rows. These shelves have the form shown in Figs. 5 and 6, the bottom shelf next the source of heat having the form. of Fig. 6, the next above that having the form of Fig. 5, the third that of Fig. 6, only shortened and not perforated at S, and so on alternately throughout the series, no matter how many shelves may be employed. These shelves are preferably embossed on their upper surface with slightly-raised projections E E, which may be of any form which will tend to cause the downflowing sheet of water to diffuse itself more evenly over the surface of the shelf. The lower shelf and those of similar form in the series are cut away on the sides, as shown at F in Fig. 6, the object being to provide a spacebetween the edge of the shelf and the wall of the inner shell B for the circulation of the heat. The other shelves in the series, being each alternate shelf, are provided with a central longitudinal opening G for the same purpose. The edges of these shelves, as well as of the various openings therein aforesaid, are turned upward, so as to confine the iiowing water upon the shelves except at the discharge ends.

The casing A and shell B of my waterheater, together with the shelves D and their openings F and G, are oblong in plan, as shown in Figs. l, 5, and 6, and are thusreadily made of the required capacity to insure heating a sufficient quantity of water in an apparatus of given height and width occupying the least possible space, while a free and effective circulation of the hot air is provided for through and around the successive shelves transversely as well as longitudinally back and forth beneath the successive shelves, so as to fully utilize the combustion of gas and render the fiow of heated air unobstructed and uniform.

H is the water-supply pipe, which terminates within the interior of my device in the rectangular double-armed or T-shaped pipe I. (Best shown in dotted lines in Fig. l.) The pipe I is provided with a number of small holes upon its under side for the escape of the water received from the supply-pipe.

IOO

acti'iating-handle of the gas-valve M.

J in Fig. 2 is a curved trough placed parallel with and a slight distance from the pipe I to serve the purposes of a baffle-plate, so that the small streams of Water which issue with force from the pipe I may impinge upon the baille-plate J and be broken up. The baffle-plate J is provided with openings of its own,through which the water impin gin g upon it may escape gently onto the upper shelf and be as evenly diffused thereon as possible.

The water-supply pipe I-I is provided with a horizontal spigot-valve K, actuated by the long arm L. This arm L is so locked into the wheel-shaped actuating-handle of the gasvalve M by means of a notch m, Fig. l",`in

said handle that the gas-valve Cannot be opened and the gas admitted. to the heatingburner Without Iirst raising the arm L and thus openin g the water-valve K and starting a flow of water through the device, the object being to render it impossible to injure the `device by applying the heat while the device is dry.

N is the gas-supply pipe, provided with'a subsidiary pipe O, terminating in a small P is the air-mixer, attached to the heatingburner Q. The burner Q is placed lin the position shown in Fig. 2. It is provided on its upper surface with a number of saw-slits or other oriiices for 'the escape of the gas.

S, Figs. 2, 4, and 6, is the hot-water discharge.

The inner shell and the Vshelves of my water-heater may be made of sheet-copper or any other suitable material. The outer shell A, being merely for ornamental purposes, may be made according to taste.

My device is operated as follows: The arm L, Fig. 2, is raised, so as 'to disengage the This starts the water, which escapes from the pipe I onto the baflie-plate J, and thence flows 'in a thin sheet over the inclined surface of the upper shelf toward its lower end. Thence 'it escapes, as indicated by the arrows, from shelf to shelf until it finally makes its escape at the hot-water exit S at the bottom of the device. As soon as the gas-valve is freed,by raising vthe arm L of the Water-valve or it may be previously, gas is admitted to the subsidiary gas-pipe O and its burner is lighted. The main gas-valve M is then 'opened and the gas sent into the heating-burner Q through the air-mixer P to insure perfect and smokeless combustion. As the mixed air and gas escapes from the heating-burner Q through the oriiices -R R the gas is ignited by the subsidiary burner attached to the pipe O, and the device is in operation and will act continuously until stopped. Vhen the device has served its purpose for the time beingthe main gas-valve M is closed, which extinguishes the heating-burner. The arm L from t'he water-valve is then brought downward and locked into the actuating-handle of the main gas-valve, which shuts off the supply of water. Lastly, if not before, the gas is shut off from the subsidiary pipe O and 'the device is at rest until `next required. As soon as the water is turned off the shelves D drain themselveslsuceessively, so that -they may be and are dried by the retained heat. l

Having thus described my invention and its mode of operation, what I cl-aim `as new, and desire to patent, is-

1. In -a water-heater, the combination with a shell having an air-exit at top, means for introducing running water at the top of said shell and a heat-generator at its `bottom, of a water-exposin g and sel'f-drainingshelf above said heat-generatorprovided ori-'top with iiowd-i'ffusing projection-s, substantially as Ahereinbe'i'ore specified.

2. The combination, i'n a water-heater `oblong i-n plan, of a water-supply pipe at top, terminating at one end of the heater in la T- shaped pipe the cross-piece of which is pe-rforated at bottom, a lperforated baffle-plate beneath said cross-piece, `a Vseries lof waterexposing shelves, a shell within which `said shelves are supported one below another, a heat-generator beneath the lowest shelf, a-nd a hot-water discharge at bottom, substantially as herein'before speciiied. p

Signed at'the city of New York,inthe-county of New York and State of New York,this '1st day of October, A. D. 1896.

ALBERT F. TRAGESER.
