CHARLES I-I. GRUB, OF PORTAGE, WISCONSIN.

SUBMEFIGED HEATER.

Specification of Letters Patent.

Patented NOV'. 14, 1905.

Application iiled July 20,1905. Serial No, 270,565. i

To all whom it may concern:

Be it known that I, CHARLES I-I. GRUB, a citizen of the United States, residing at Portage, in the county of Columbia and State of Wisconsin, have invented new and useful Improvements in Submerged Heaters, of which the following is a specification.

My invention has reference to submerged heaters-. e.,'heaters designed to be used in tanks for supplying stock with water with a view of preventing the water from freezing; and it contemplates the provision of a submerged heater which is at once simple and inexpensive in construction, economical in the use of fuel, and highly efficient in preventing the formation of ice in a tank even when the weather is extremely cold.

The invention will be fully understood from the following description and claims when taken in connection with the accompanying drawings, forming part of this specification, in which- Figure l is a longitudinal vertical section of the submerged heater constituting the present and preferred embodiment of my invention. Fig. 2 is a transverse section taken in the plane indicated by the line 2 2 of Fig. l looking-toward the right. Fig. 3 is a horizontal section taken in the plane indicated by the line 3 3 of Fig. l looking downwardly. Fig. 4 is a plan view illustrating the heater in combination with a receptacle for holding hot water and the tank for supplying stock with water, the heater being arranged in the hotwater receptacle, which in turn is disposed in' the tank. Fig. 5 is a longitudinal vertical section taken in the plane indicated by the line 5 5 of-Fig. 4, and Fig. 6 is a transverse section taken in the plane indicated by the line 6 6 of Fig. 4.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which- A is the body of my novel heater, which is preferably oblong in shape and is made of metal suitable to the purpose. The said body is provided in its top with an opening designed for the introduction of fuel and normally closed by a hinged and vertically-swinging door a and is also provided with a smoke-pipe Z), extending upwardly from its top adjacent to one of its ends. In the door a, adjacent to the swinging end thereof, is an opening c, controlled by a horlzontally-swinglng cover Z and designed for a purpose presently set forth.

B is a iire holder or box disposed in the lower' portion of the body A. The said fire holder or box is preferably formed by a bottom which may be the bottom wall 'of the body A or a wall e, perforated, as shown, or imperforate, supported above the bottom of the body, the end walls of the body, and water-tubes C, communicating with the exterior of the body and designed for the circulation of water in close proximity to the lire with a View of accelerating the heating of the water. rlhe said tubes C constitute the side walls of the fire holder or box and by protecting the side walls of the body A against the high heat materially prolong the usefulness of the heater as a whole. In the preferred embodiment of my invention illustrated the tubes C are arranged longitudinally and one above the other at opposite sides of the fire holder or box, have their ends extended through the opposite end walls of the body A, so as to conduct water through the body, and are inclined in the direction of their length, this latter in order to enable the water to follow its natural tendency of rising when heated and in that way assure the maintenance of a suiiicient circulation of the water in a tank with a view of preventing freezing' of such water. It will also be noted that the fire holder or box constructed in the manner shown and described is of the same length as the body, and hence admits of long sticks of wood being laid lengthwise in the heater, as is desirable.

D is a draft-tube which is iixed in the body A in position to register with and receive air from the opening c in the door a and extends downwardly between the pairs of tubes C and communicates at its lower end with the space below the bottom wall e of the iire holder or box B, so as to supply to said holder or box suiiicient air to support comb'ustion. In virtue of the location of the said tube D-rL e., its arrangement between the pairs of tubes C and in one end of the lire holder or box-the air passing through the said tube is highly heated precedent to being discharged into the lire holder or box, and in this way combustion of the fuel in the heater is promoted.

E is a wall fixed in the body A above the tubes C and at the end of said body remote from the draft-tube D. The said wall E is provided with an opening f for the upward passage of smoke and other products of combustion and is preferably retained in position through the medium of bail shaped hangers F, connected to and depending from the top wall of the body A. The said bailshaped hangers and the connection of the same to the wall E and the top of the body A are in no way liable to be affected by the heat, and hence it follows that the said hangers contribute materially to the durability of the heater as a whole.

Gr is a vertically-swinging' door hingedto the wall E and designed when in its normal position to prevent smoke and products of combustion from passing above the wall E except by way of the openingf therein. H is a cable, preferably a chain, connecting the door Gr and the door a, so that when the latter door is opened for the introduction of fuel the door G will also be opened, and M is an imperforate deflector-wall fixed in the body A above the wall E. By virtue of the arrangement just described it will be observed that the heated gases and other products of combustion must in passing from the fire holder or box B to the smoke-pipe take through the opening f in the wall E and around the deflector-wall M. In other words, the heated gases and other products of combustion after passing through the opening f are conducted horizontally first toward the left and then toward the right in the upper portion-of the body A, and from this it follows that practically all of the heat value of the said gases and other products of combustion will be utilized in heating the upper portion of the body A and the water surrounding the same before the gases and other products of combustion pass out of the heater through the smoke-pipe b.

My novel submerged heater is designed to be used in the manner common to submerged heaters-that is to say, it is adapted to be placed in a tank of water with the top of its body above the surface of the water. I prefer, however, to employ the said heater in combination with the hot-water receptacle P andthe tank R for supplying stock with water, as shown in Figs. 4 to 6.l

The receptacle P, which is preferably of sheet metal, is arranged in the tank R adjacent to one end of the latter and is of such a size that the heater occupies about one-half of its width and extends from a point adjacent to one of its end walls to a point adjacent to its opposite end wall, as shown. Said receptacle P is provided with a hinged cover S for covering its portion at one side of the heater, and it is also provided with a cock T, extending through one of its end walls and designed when open to connect its lower portion and the interior of the tank R, and a cock U, extending through its opposite end wall and designed'when open to connect its upper portion and the interior of the tank.

By reference to Figs. 4 to 6 it will be observed that with the heater in operation water will circulate from the interior of the tank through the cock T into the receptacle P. lVhile in the said receptacle P vthe water will pass through the tubes C of the heater and by reason of such passage and its confinement in proximity to the heater will be quickly heated. From the receptacle P the water will pass through the cock U back into the interior of the tank R.

By reason of the water circulating from the interior of the tank R through the receptacle P, the heater and the said receptacle P, and back into the interior of the tank it will be observed that freezing of the water in the tank will be prevented even when the ternperature is very low. It will also be observed that the water in the receptacle P is at all times warm and may be readily dipped therefrom when the cover S is raised. It will further be observed that by closing both cocks T and U the water thereby confined in the receptacle P may be quickly heated to adapt it for making swill in real cold weather.

It will be gathered from the foregoing that while the receptacle P materially increases the efficiency of the heater it adds but little to the cost of installing the same.
