UNITED STATES PATENT UFFTQE.

HAROLD J. LUMLEY, OF BUFFALO, NEW YORK.

. HOT-WATER HEATER.

Application filed October 15, 1918.

To all whom it may concern:

Be it known that I, HAROLD J. LUMLEY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in HotWater Heaters, of which the following is a specification.

This invention relates to hot water heaters.

The object of the invention is to provide a water heater for use in connection with a burner of an ordinary gas cook stove so con structed that it will not interfere with the normal use of the burner thereby adapting the burner to perform the double function of a cooker and a heater.

Another object is to provide a heater of this character equipped with an improved flame spreader constructed to deflect the flame both on to the heater coil and on to a vessel containing material to be cooked.

With the foregoing and other objects in 7 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 invention 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 partly in section of a stove and boiler equipped with this improved heater, and

Fig. 2 is a top plan view of the heater coil with the pipes which connect it to the boiler broken off for convenience in illustration.

In the embodiment illustrated a water tank or boiler B such as is usually used in connection with coal ranges and which is usually of a thirty gallon capacity is shown supported in the usual way. A gas range R is also shown having the usual burner B.

The boiler B is provided at its upper end with the ordinary outlet 0 from the hot water and with a supply pipe S and at its lower end is equipped with a drain cock C. All of these parts are of the usual construction and constitute no part of the invention.

The heater constituting the invention comprises a coiled pipe 1 of a size to fit over the burner B of a cooking range, said heater being here shown in the form of two coils arranged one. over the other and spaced apart a suitable distance to permit Specification of Letters Patent.

Serial No. 258,136.

the heat and flame from the gas burner to pass around both coils. The pipe from which the coil is formed extends therefrom in vertical parallel relation, the arms 2 and 3 of which are equipped at their outer ends with couplings 4 which unite them to pipes 5 and 6. The pipe 5 leads to the top of the boiler B and is designed to conduct the Water heated in coil 1 to the top of said boiler while the pipe 6 leads to the bottom of the boiler and is designed to supply water from the boiler to the heater coil, the circulation being kept up through these pipes, the coil and the boiler in the usual manner with devices of this character.

' A flame spreader 7 is detachably connected with the coil 1 and is made in the,

form of a concavo convex disk disposed above the uppermost coil and having spring clips 8 adapted to extend between the coils and to clamp over the lowermost as is shown clearly in Fig. 1. These clips 8 are made double hook or substantially S-shaped. This spreader is so positioned relative to the coils that the flame passing from the burner B coming in contact therewith will spread outwardly and be deflected on to the coils of the heater as well as directed against the bottom of the vessel which contains the material to be cooked and is positioned over the burner on the stove in the usual manner.

With a heater constructed as above described the cooking operation may be performed by the same burner which heats the boiler and the water will be heated sufficiently for all ordinary uses required during the day.

When it is desired that the boiler shall be full of heated water at the boiling point such as is necessary on washday and the like, the burner B may be lighted and left with the gas turned on about one-third or one-half when retiring and in the morning the tank or boiler will be full of hot water at the boiling point. The water so heated may be kept at the boiling point with the burner turned just as low as it can be with out going out.

From the above description it will also be obvious that the heater constituting this invention may be applied to any ordinary gas cook range by simply perforating one side wall to permit the passage of the pipes 2 and 3 and these pipes are held secure to the stove 'by clamp nuts 9 and 10, one arranged inside the wall of the stove and the other outside as is shown clearly in Fig. 1.

The pipes 2 and 3 may be coupled in the usual manner by couplings i with the pipes 5 and 6 which lead from the boiler 13 and which are usually connected with the Water back of an ordinary coal range. The burners therefore may he cheaply constructed and placed 011 the market and connected up by an amateur, the only change in the range being the apertures through which the pipes 2 and 3 are to pass. When one of these heaters has been applied to a gas range great, eco'nomy in gas Will be effected OVGI' an ordinary water heater used for this purpose in that it permits the burner to be used to perform its usual functions, the heating of the water being an auxiliary function.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

Having thus fully described my invention, what I claim as new and desire to se cure by Letters Patent, is

1. The combination with a heater of the class described comprising a pipe including a plurality of superposed coils; of a flame spreader arranged over said coils, and spring clips carried by said spreader and detachably engaged with one of the coils.

2. The combination with a heater of the class described comprising a pipe including a plurality of superposed coils; of a concavo-convex disk-like spreader arranged above the upper coil, and spring clips carried by said spreader and having hookshaped ends connected with one of the coils.

In testimony whereof I aflix my signature in presence of two witnesses.
