BUILDERS PORTABLE HOT-WATER HEATER.

Application filed January 7, 1916.

To (all whom it may concern.-

Be it'known that I, CHRISTIAN A. LON- DELIUS, Jr., a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Builders Portable Hot-Water Heaters, of which the following is declared to be a full, clear, and exact description.

This invention relates to improvements in builders portable hot water heaters and its primary object is to provide a novel hot water heater, capable of being placed in or about an unfinished building during the course of its erection, and connected with the water supply of the building.

It is well known to those skilled in the art to which this invention pertains that during the cold weather it is necessary to heat'water for use in mixing concrete, cement and the like, and many attempts have been made to provide a water heater suitable for this purpose.

One of the objects of this invention is to provide a portable hot water heater, which may be readily carried about and placed at any desired location in the building, and which may be readily emptied of its contents after the days work is done, so as to avoid danger of the water freezing in the heater, when the same is not in use for any length of time.

With these and other objects in view, this invention consists of the several novel features hereinafter set forth, and particularly pointed out in the appended claims.

This invention is clearly illustrated in the accompanying drawing, in which Figure 1, is a central, vertical section through a builders portable hot water heater, embodying a simple form of the said invention; Fig. 2, is a plan thereof; Fig. 3, is a horizontal section taken on the line 83 of Fig. l, and Fig. i, is a side elevation of a fragment of the hot water circulating system.

Referring to said drawing, the reference numeral 10, designates a tubular shell or casing, supported by legs 11, secured to the lower end of said shell or casing in any suitable manner as for instance by rivets. The shell is open at the top and bottom, and its upper end is closed by a cover 12, that rests upon the top of the shell, said cover having a large opening 13, which is covered Specification of Letters Patent.

by a lid, let, hinged to the cover by hinges 15. In the lid 14, is a draft opening 16, for aiding combustion in the fire box or combustion chamber. The large opening 14, furnishes access to the interior of the shell and the fuel may be inserted through said opening. Secured on the inner wall of said shell 10, near its lower edge, is an annular angle iron 17, which furnishes a shelf or ledge for supporting coils of pipe 18, through which the water is circulated. Said colls of pipe comprise vertical coils 19, 19 and horizontal pipes 20, connected with the lower ends of said vertical pipes in such a manner as to form a continuous passage for water extending from one end to the other of the several coils of pipe. In the embodiment of the invention illustrated in the drawings, the pipe 18 is the inlet pipe, and it has extension 21 at its upper end which leads out over the top of the shell 10, and has a shut-elf valve 22, therein, whereby the supply of water to the coils may be regulated. The extreme end of the pipe 21, is arranged for connection with a hose or other flexible pipe 23, which leads to and is connected with the water supply of the building. The pipe 18 is the discharge pipe of the hot water heater and has an upward extension 24, extending up and over the top of the shell, and arranged for connection with a hose or other flexible pipe 25, the end of which may be carried to the point where it is desired to deliver the hot water. The connections between the extensions 21, 24 and hose 23, 25, comprise the usual screw threaded connections, common and well known to those skilled in this art.

In the embodiment of the invention illustrated herein the lower end of the inlet pipe 18 connects with the lower end of a plurality of connected vertical coils 19 as illus trated in Fig. 4, and the lower end of the last pipe of said upright coils 19 connects with the first one of the horizontal pipes 20, which pipe runs across to a point adjacent the inlet pipe 18 where said horizontal pipe 20 connects with the lower end of an upright pipe of the upright coils 19*. lower ends of each upright coil 19 are connected to horizontal pipes 20, which extend across to the lower ends of the upright coils 19, on the opposite side of the heater, so as to form a continuous circulating system The 1 through the upright and horizontal pipes. The discharge end of the circulating system is formed substantially as is the inlet end whereby a series of vertical pipesare provided, which extend along the inner face of the shell, and a series of horizontal pipes are provided which extend across the bottom of the shell to act as grate bars for supportingv the fuel in the combustion chamber thereabove.

In use, the shut-off valve 22, is opened to permit water to flow into and fill the water circulating system of the hot water heater, after which said shut-0E valve is closed. Fuel is placed in-the combustion chamber and is ignited, and the water is heated thereby. Preferably suiiicient fuel is placed in the heater to cover the vertical coils of pipe and inasmuch as coke is usually used as fuel it creates an intense heat, thereby quickly heating the water contained in the circulating system.

When it is desired to draw hot water, the shut-0E valve 22, is opened, whereby the pressure from the source of water supply forces the water out of the water circulating system of the heater and discharges it through the hose, 25.

At the close of the day, the coils of pipe may be bodily removed from the shell, one

of the hose detached from the coil of pipe and the latter may be laid upon its side to drain it of all the water contained therein, thus avoiding any danger. of freezing.

More or less variation of the exact details of construction is possible without departing from the spirit of this invention, and I desire, therefore, not to limit myself to the exact construction shown and described, but intend in the following claims to point out all of the inventions disclosed herein.

I claim as new and desire to secure by Letters Patent:

1. A builders portable water heater, comprising a shell open at the top and bottom, supporting legs therefor arranged to support the open bottom of the shell in an exposed condition free from the object on which the heater stands, a cover for the open top of the shell, a water circulating coil removably supported in the shell and having a large surface area, the ends of said coil being arranged for connection with flexible inlet and discharge pipes, said water circulating coil having closely spaced pipes arranged close to the inner face of the shell and having horizontal closely spaced pipes arranged adjacent the open bottom of the shell, said coil forming the fuel supporting means for the heater and the entire structure being readily portable.

2. A. builders portable water heater, comprising a shell open at the top and bottom, supporting legs therefor arranged to support the open bottom of the shell in an eX- posed condition free from the object on which the heater stands, a cover for the open top of the shell, a water circulating coil removably supported in the shell and having a large surface area, the ends of said coil being arranged for connection with flexible inlet and discharge pipes, and a shut oif valve on one of said ends of the coil, said water circulating coil having closely spaced pipes arranged close to the inner face of the shell and having horizontal closely spaced pipes arranged adjacent the open bottom of the shell, said coil forming the fuel supporting means for the heater and the entire structure being readily portable.
