WATER-H EATER.

Specification of Letters Patent.

Patented Feb. 12, 1907.

To all whom, it may concern.-

Be it known that I, HERBERT S. HUM- PHREY, a citizen of the United States, residing at the city of Kalamazoo, county of Kala mazoo, State of Michigan, have invented certain new and useful Iniproveni ents in Wat er- Heaters, of which the following is a specification.

This invention relates to improvements in waterheaters.

It relates particularly to the class of waterheaters known as instantaneous, such as is shown and described in Letters Patent of Alfred H. Humphrey, No. 704,043, dated July 8, 1902, and it is an improvement thereon and in some respects a modification thereof.

The objects of this invention are, first, to provide an iniproved water-heater which is sirr ple and compact in structure, of large capacity, and economical to use second, to provide an improved water-heater to which the water is so delivered and distributed as to be brought into such contact with the heated air or gases arising form the burners as to quickly absorb the heat therefrom.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined, and pointed out in the claims. I

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a detail vertical sectional view of my improved water-heater, the burners and the gas and water pipes being shown in full lines. Fig. 2 is an enlarged detail vertical sectional view of the sprinkler-head, taken on line 2 2 of Fig. 3. Fig. 3 is a crosssectional view taken on line 3 3 of Fig. 2. Fig. 4 is a plan view of the upper end ofthe tube G.

In the drawings similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, I provide an outer casing A; which is preferably cylindrical in form. This casing rests upon a suitable base A, which is preferably provided with a bracket at one side, as a, by which it may be secured to the wall or to any other suitable support. It may of course be arranged to rest upon its own case. The casingAis provided with a flue a at the top for the escape of the gases of combustion. In the lower part of the cesingA suitable burners, as B, are arranged. These burners are connected by the pipe B to a suitable gassupply. It is evident that other means night be err ployed for delivering heated air or gases to the base of the casing, although I prefer to arrange the gas-burners therein as shown in the drawings.

Arranged above the burners B is an open- I ended conical tube G. This tube is corrugated at its upper end, as is clearly illustrated in the drawings. The base of the tube G is adapted to fit the walls of the easing A and is secured thereto, thereby forming a water-receptacle for the heated water between it and the walls of the casing. A delivery-faucet, as H, is provided for this receptacle. An inverted conical or funnelshaped plate F, having a central opening through which the upper end of the tube G is arranged, is provided. The periphery of this plate also fits the walls of the casing and is secured thereto. The corrugations in the upper endof the tube G form passages for the water from the plate F to the outside of the cone. Awater-delivery pipe C is arranged centrally in the casing through the tube G. This pipe is provided with a spraymg-head C at its upper end. The water-delivery pipe C is provided with a stop-cock or valve C. Above the upper open end of the tube G is a deflector-plate E. This deflector-plate E prevents the water from above entering the tube G and also spreads out the heated air or gases delivered from the upper end of the tube G. The plate E is preferably supported on the water-delivery pipe 0. Above this deflector-plate E are perforated baffle-plates D, one of which is arranged above the spraying-head C and the other below it. These perforated baffle-plates are conical in form, and the lower one is arranged in an inverted position, and the upper one rests thereon. They extend completely across the casing A, forming partitions therein, as clearly appears from the drawings. The spraying-head C consists of a frame 0, which is mounted on the upper end of the water-delivery pipe. Pivotally mounted on this frame is a spraying-wheel c, which is shaped somewhat like an inverted cup. The fans or blades of this wheel are formed by slitting and deflecting portions thereof. The force of the water revolves this wheel, and the water is evenly distributed thereby to the baflieplates.

In operation the gas and 'the water are preferably turned on simultaneously. The water is delivered by the sprinkler-head C to the under side of the upper baffle-plate and to the upper side of the lower baffleplate. The sprinkler-head C is preferably arranged in the apex of the upper bafiieplate, so that the greater portion of the water is delivered to the under side thereof and flows or drips therefrom to the lower baffleplate. These baffle-plates are conical in form, so that the tendency of the water is to flow down the same and in doing so seal or partially seal the perforations, therein. The heated air and gases or combustion pass up through the cone G and impinge against the under side of the deflector-plate E, by which they are spread, so that they are quite evenly delivered to the under side of the lower baffle-plate, through the perforations of which they pass, breaking through the films of water, over the perforations, coming thereby in close contact therewith, so that the water readily takes up the heat therefrom. The

heated air and gases pass on through the space between the baffle-plates in which water is being delivered by the spraying-head C and through the perforations in the upper baffle plate and are carried off by the flue a. The

water and the heated air or gas are thus brought so thoroughly into contact that the water practically absorbs all the heat thereof. The water passing down to the deflector-plate E, which has become heated, absorbs more heat. The water is delivered by the deflector-plate E to the plate F, by which it is delivered into the tube G. This tube or cone G is also heated, so that by the time the water reaches the base of the tube it is thoroughly heated.

By thus arranging the parts I am enabled to utilize a maximum of heat units generated by the burner. The heater is very compact and simple and economical to produce and is of very large capacity. The parts are so arranged that they are very durable, and the structure is not liable to get out of repair or become clogged by use.

I. have illustrated my improved waterheater in the form preferred by me on account of its simplicity and durability and economy in use, although I am aware that the structural details may be varied without departing from my invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is
