WATER-HEATER.

Specification of Letters Patent.

Application filed February 24, 1915. Serial No. 10,291.

To all whom it may concern Be it known that I, CHARLES E. REED, a citizen of the United States, residing at Bartow, in the county of Polk and State of Florida, have invented certain new and useful Improvements in Water-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill'enable'others skilled in the art to which it appertains to make and use thesame.

This invention relates to water heaters, and more especially to those including a stand boiler within a casing; and the ob ect of the same is to provide means for heating the Water in such a boiler by a fluid fuel burner which is bodily insertible in or removablefrom the lower portion of the easing or jacket, which latter therefore becomes a flue carrying the products of combustion upward around the boiler. to an outlet.

A further object of the invention is to improve the means for supporting the heater so that as a unit it may be bodily withdrawn for cleaning, repairing or filling its tank.

A still further object of the invention is to improve the structure of the stand on which the device is mounted. I

The following specification setsforth the preferred manner of carrying out my invention, reference being had to the accompanying drawings wherein Figure 1 is a central vertical sectional view of this heater complete. Fig. 2 is a perspective detail of the shelf and slide on an enlarged scale. Fig. 3 is a similar enlarged sectional detail of the stand, and Fig. 4 a. still further enlarged detail showing the manner of connecting the jacket with the stand.

The stand boiler B illustrated in the drawing is that now in general use and by preference I employ one measuring 36 inches in length and about 10 inches in diameter, and the inlet and outlet pipes I and p O are those usually employed. It is quite possible that the inlet pipe, instead of taking its water from the house s stem direct, may have taken it from the 0011 within the furnace or the water-back within the range, and if: either case the Water flowing in at the point I will be warm'or hot if there is fire in the furnace or range. If such is the mannor in which the boiler is connected up, then my improved water heater finds its greatest But ordinarily this device is employed where Patented @0111. 12, 1915..

there is no furnace, and cold water is admitted at I and heated by the means described below, so that Warm or hot'water is drawn out at O and carried to-the point of use. Besides inlet and outlet pipes, there is a mld-length pipe M leading from a point at about the center of the height of the boiler to a point E where it enters its lower end, and this pipe may have its own faucet F. This supplemental pipe is also often'employed where the boiler is connected with the furnace, and I lay no claim ofnovelty thereto.

Coming now to the details ofthe present invention, I inclosethe boiler B within an upright cylindrical jacket 1 which surrounds it and is connected with it by brackets 2 or any suitable devices holding the walls of these elements slightly spaced so as to produce an annular flue or jacket space around the boiler, and the upper end of the casing or jacket extends above the top of the boiler and'is shaped into an outlet 3 from which the products of combustion may escape in any suitable manner. The lower end of the jacket depends to a considerable-distance beneath the bottom of the boiler, has an opening 4 in its front side, and rests at its lower edge upon a 'stand best seen in Figs. 3 and 4. This stand comprises a ring 5 pierced with abo'ut three holes 6 and with two diametrically opposite eyes 7. Into said holes are screwed the upper ends of/legs 8 which are preferably of pipe having rather lon threads for purposes of adjustment, an lock nuts 9 upon the threads as best seen in Fig. 1. The lower end of each leg may have a foot 10 secured by a screw 11 or. otherwise to the floor. Riveted within the jacket at points quartering to its front 0 ening 4 are two L-armed brackets 12 w ich stand above the eyes 7 and small bolts 13 The heating unit of itself may be anywhich will operate successfully in conjunc- 'tion with the boiler and its jacket, but preferably it will employ a burner 20 for fluid fuel. While said fuel might be gas led to the burner through a pipe or hose so that the user could employ natural or artificial gas if desired, in many sections of the country the fluid fuel will be oil and the burner must be of a type which will vaporize and burn such oil. In other sections of the country the fuel willbe kerosene which is always readily obtainable and cheap, and I will illustrate and describe the heater as of this type. From the burner 20 leads a pipe 21 to a casing 22, here shown as having legs 23 rising from a sheet metal slide 24, and within said casing is rotatably mounted a tank 25 having a knob or handle 26 on one end of its axis so that the tank can be turned and the liquid will flow into the casing 22, and thence along pipe 21 to the burner 20. Secured to and rising from the slide at a point about midway between the tank and burner is an upright sheet-metal shield 27 pierced with a,hole 28 for the passage of the pipe 21, and this shield is of a size and shape td close the opening-4 when the slide stands in such position that the burner is centered within the lower end of the jacket. The midlength or system of pipes M I now preferably provide with a coil 29 disposed beneath the boiler. and directly above the burner, and therefore the flames rising from the burner heat this coil and the water within it, then heat the bottom of the boiler, and finally flow upward through the jacket space and heat the sides of the boiler. It'. will hardly be necessary to amplify the illustration to show that the pipe 21 might be a hose connected directly with the natural or artificial gas system if the dwelling be so provided, but even in that event I would have the slide movable as will be next described.

Extending through the bottom of the opening 4- in the jacket and over the ring 5 to its rear. side as indicated in dotted lines in Fig. 3 is a sheetmetal shelf 30having its side edges beaded or turned upward and inward into guides 31 as best seen in Fig. 2. This shelf is as wide as the opening 4 but of less width than the internal diameter of the jacket, and its length is such that it extends through the opening and beyond the jacket about as far on the outside as it does on the inside. The sheet-metal slide 24 has its side edges turned downward and then outward into flanges 32 which are adapted to slide under the guides 31, and the front end of the slide is curled downward into a'handle 33. All of the parts are of course of metal.

With the above construction and after the device'has been set up, we may assume that the part stand as seen in Fig. 1. The operator now grasps the handle 33 and draws thelslide outward on shelf 30 so that the shield 27 comes out of the opening 4 and the burner 20 follows it through said opening, at least to a position where it can be lighted. If the supply be a rotary tank as shown at 25, it is controlled by means of the knob 26. If the fuel is gas led through a flexible pipe 21, it will be controlled by the usual cock. In any event the fuel is permitted to flow to the burner and a match is applied, and then the entire heater is moved by shoving the slide 24 inward so that its flanges 32 move under the guides 31, and its burner.

20 comes to rest directly beneath the coil 29 at the time that its shield 27 closes the opening 4 inthe jacket 1. Air is now admitted through the ring 5 of the stand on either side of the shelf to supply combustion to the burner, and the flames rising therefrom heat the coil and the boiler as above explained. By actual tests from a working machine I have found that I can raise the temperature of the water thirty degrees in thirty minutes, and the operating cost with kerosene at fifteen cents a gallon is about one and one half cents an hour. Manifestly the cost would difler with other kinds of fuel, or it would be much less if the heater were employed to raise the temperature of water which was already warm when it was fed in at the point I. In other words, it often occures that the heating system connected with the furnace or range is not such as will more than warm the water in the stand boiler, and for laundry and other purposes a supplemental heater is desirable unless one'be willing to considerably increase the heat in the regular system. As above stated, this device can be used when there isno fire in the house, or it could be installed Where the boiler has no connection with the furnace or range. At P in Fig. 1 is shown a peep hole through the acket 1, which may well be covered with mica held within a removable frame or otherwise, and through the same the flame can be seen at any time.
