WATER-HEATING APPARATUS.

Specification of Reissued Letters Patent.

Reissued Nov. 7, 1905.

My invention relates to an improved appa-' ratus for heating and supplying hot'w ater to a house, in which apparatus there is a plurality of heating means; and it consists of an annular boiler having a passage or space through its center extending from its bottom to its top. Inside of this internal passage or space I place a water-heater which extends from the bottom to the top of the space and fills it entirely. The bottom of the water-heating device is connected with the main water-supply, while its upper end is connected with the top of the boiler and with a solar heater on the roof of the house. The upper end' of the space within the boiler is connected by a flue with a chimney or Stovepipe-flue, and provisions are made for connecting the boiler with the water-back of a stove, While the heaterin the annular space is heated by a gas burner below the space and heater, all as hereinafter more fully described.

Referring to the accompanying drawings,

Figure 1 is an'elevation of my Water-heating apparatus, showing the boiler in section.

Fig. 2 is a bottom view of one of the heatersections, and Fig. 3is aside view'of two of the heater-sections.

of uniform diameter extending from its botit and fills the space from the top to the bottom of the boiler. This inclosed water-heater may be of any convenient form; but the one which I have shown consists of a series of castings with radiating arms F, connected by a central tube, the exterior shape of which conforms to and fits in the annular space, as shown at Fig. 2. This style of heater may be used throughout the length of the space in the boiler, or other forms of heaters could be combined with it. shown a radial-armed heater, such as is above described, occupying the middle part of the annular space and a spiral pipe-section G below it and extending down to the bottom of the space. The upper. end of this spiral pipesection connects with the central pipe of the radial-armed section, and another spiral pipesection H connects with the upper end of the radial-armed-section and fills the space 'be-' tween the radial-armed section and the top of the boiler, thus completely filling the central spacej The lower end of the lower spiral section G is connected with the water-main by a pipe M, which connects with the mainpipe K, which latter supplies water from the water-main to the boiler. This latter pipe may pass down through the boiler or outside of it, as preferred, and is provided at a suitable point with a stop-plug is.

A gas-burner E is mounted below the annular space, and an air-pipe D leads from the basement or outside of the house to supply air to support combustion of the burner.

A horizontal pipe L is connected with the pipe K just below the gas-burner and leads across below the burner and connects in the usual way with the water-back of the stove C, said pipe being also connected with the bottom of the boiler, where it passes underneath it. A cock 6 in the length of the pipe serves to shut ofi the supply of water to the water-back and to the boiler when desired. ,Saidpipe M connects with the main pipe K and passes up through the gas-burner E and to the heater, and a cook 01 serves to shut off the water-supply to the inclosed heater.

From the topof the heater an extension-pipe P, which connects with the water-heating device, leads up to a solar heater on the roof of the house, said pipe passing through the elbow or bend in the flue-pipe J in its passage upward.

The'arrangement of thesolar heater and of the pipes leading to and from the same may be In the drawings I have such as is shown in United States Patent, issued no part of my invention I refer the 15m} 'patent to indicate the type or arrangement that is applicable. p Below the pipe M a downpipe O leads'fro'm the solar heater'on the roof, the lower end of which pipe is connected with the pipe K. A cock fin this-pipe O and a cock 9 in the'extension-pipe P serve to shut ofl connection with the solar heater. v

A horizontal pipe Q, extends, out from the upright pipe P directly across the top of theboiler and connects with the pipe S, and directly above the boiler a cross-pipe R is connected with the pipe Q, the lower vertical water.

member of which pipe R passes down into the .top of the boiler, while the upper vertical only cut ofl from the basement-heater, butit is compelled to pass into the boiler and waterback. A cock l between the pipe S and the boiler closes the connection with the boiler.

It is evident that the solar heater andthe. heater in the basement may be dispensed with, in which case the pipes that connect them with the system are not used. I By this arrangement and system of heaters and pipe connections a large quantity of water can be quickly heatedpbecause by opening all the cocks the several heating devices can be concentrated upon the water in the boiler, and by shutting off the water from one or more the capacity of the boiler is regulated according to the requirements. Theannular form of the boiler renders it not only convenient, but very effectiveas the. heat generated by the gas-heater is confined and entirely utilized.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is

1. In a water-heating apparatus an annular boiler having a space extending entirely throughout the center thereof, in combination with a stovepipe having one of its ends arranged in the space of said boiler, a waterheaterlocated'within space and in com- -munication with the supply, a vertical pipe communicating with said water heater at its upper end and leading through said stovepipe, a horizontal pipe connected to said vertical pipe and extending through the side of said stovepipe, and a pipe connected to said horizontal pipe and, leading into the top of said boiler, andasu pply-pipeK extending through the boiler and having connection with the water-heater, a conn'ection'between said pipe K and the water-back of the stove, and a pipe Tconnected to'said water-back andsaid boiler.

2.' In a Water-heating apparatus, an annular boiler having a space extending entirely through the center, a Water-heater located within said space and extending the entire length of the same, in combination with the stovepipe of the same diameter as said space and leading into the top of the same, a pipe K connected to said -water-heater, a vertical pipe P connected to saidwater-heater, a horizontal pipe connected to the vertical pipe and a pipe R con'nected to the horizontal pipe and'leading into the boiler, a vertical pipe S connected tofsaid horizontal pipe, a connec- .tion' between pipe K and the water-back of Go I the stove, a pipe T leading from said.waterback to the boiler and having connection with r pe 3. In a water-heating apparatus, the combinationof an annular boiler having a space extending entirely through the center thereof, a heater in said central space, a fluid-fuel b'urner in the bottom of said space for heating the upper connection, substantially as clescribed.

- In testimony whereof I have signed rny name to this specification in the presence of two subscribing witnesses.
