UNITED STATES FELIX J. McG-UANE, OF CHICAGO, ILLINOIS.

WATER HEATER.

Application filed July 8,

This invention relates to a water heater for furnaces.

The object of the invention is to provide a heater of this character which is adapted to be removably mounted in a furnace and which is adjustable to be positioned in the hottest part of the fire without interfering with firing since it can be easily withdrawn for this purpose.

Another object is to provide a heater of this character which is controllable for varying the amount and the intensity of the heat of the water heated thereby.

Another object is to provide a Water heater of this character which may be easily replaced at any time with minimum trouble and expense should it become clogged with lime or sediment deposited by the water.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a side elevation of a furnace with this improved heater shown applied, parts being broken out of the furnace to show the location of the heater within it; and

Figure 2 is a detail rearelevation of the heater shown in operative position.

In the embodiment illustrated, the heater constituting this invention comprises a hollow casting 1 here shown rectangular in form and which is designed to be inserted in the fire box of a furnace shown at F. This hollow casting 1 has a horizontal partition 2 extending longitudinally thereof from its rear toward its front end and terminating short of said front end to afford communication between the space at the top and at the bottom of the partition as is shown clearly in Figure 1.

The upper chamber 3 is connected by a flexible rubber hose 10 to the upper portion of a hot water tank T while the lower compartment a is connected by a similar hose 11 with the lower end of said tank. A suitable handle is provided at the rear end of the casting so that the casting may be conveniently thrust into the fire box of the boiler or furnace or withdrawn therefrom according to the amount of hot water desired and the position in which it is desired to locate the heater.

A suitable slot is provided in the fire box of the furnace through which the casting may be inserted.

The casting being flexibly connected with the hot water tank T by a flow and return pipe shown at 11 and respectively, said casting being free to slide in and out through the slot in the furnace, it will be seen that any degree of heating capacity may be obtained by adjusting the position of the cast ing to any point desired.

When a large quantity of hot water is desired or hot water is Wanted quickly the casting is pushed all the way into the fire box while for a moderate amount it is pulled say half way out, or if the tank is too hot and the water starts to boil it may be pulled all the way out. I

This removable heater overcomes the ob jection of a permanently set coil in that it can be positioned in the hottest part of the fire box and will not interfere with firing as it can be easily Withdrawn before starting the fire and thus be entirely out of the way.

The pipes leading to the upper'and lower ends respectively of the tank T are equipped with gate valves 12 and 13 having couplin for connection of the hose 10 and 11. Should the heater become clogged with lime or sediment deposited by the water it may be easily removed and replaced by another by simply Serial No. 42,256.

unscrewing the hose 10 and 11 from the valve carried pipes which lead to, the tank, it of course being understood that the- valves 12 and 13 are first closed. After-the new heater,

has been substituted the valves are again opened and the device is ready for use. This change can be made in a few minutes by any inexperienced person thus avoiding the necessity of expensive plumbing work in addition to making the change at the time desired.

I claim In a device of the class described, a furnace having an opening, a. water heater prothat the heater may he slid by means of the 1 jetting into the furnace through the openhandle entirely out of the opening and free mg: the heater having a free, slidable, from the furnace, and he slid for adjustment metal-to-metal-contast mounting in the opento vary the amount that the heater projects 5 ing, the heater having flexible water-supply into the furnace.

connections, the heater being provided at its In testimony that I claim the foregoing 1i outer end with a hand-grip, the cross secas .my own, I have hereto eflixed my slgnationai contour of the heater bearing such reture. lation to the size and shape of the opening FELIX J. MCGUANE.
