GAS WATER-HEATER.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed ry 18, 1905. Serial No. 246,215.

To all whom it may concern:

Be it known that I, DANIEL J OI-IN F. BUCK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Gas Water Heaters, (Case No. 2,) of which the following is a full, clear, concise, and exact description, referencebeing had to the accompanying drawings, forming a part of this specification.

My invention relates to heating appliances, particularly to gas Water-heaters and its object is to provide improved and more eflicient arrangement and construction of the various heating and distributing mechanisms.

My invention may be best understood with reference to the accompanying drawings, in which Figure 1 is an elevation view of a vertical tubular boiler and heater, part of the shell being broken away to reveal interior arrangements. Fig. 2 is a top view of Fig. 1. Fig. 3 is a sectional view taken on line 3 3 of Fig.

1. Fig. 4 is an enlarged sectional view taken on line 4 4 of Fig. 1.. Fig. 5 is a sectional view taken on line 5 5 of Fig. 4. Fig. 6 is a plan view of a bushing employed in assembling, and Fig. 7 is a sectional view taken on improved primary heater 4, which will be described more in detail later. The water-inlet pipe 5 supplies water to'the primary heater and conveys the water thereto directly from a main or from the interior of the storage tank 1, in which case the cold water is delivered to the tank through the pipe 6, entering, as shown, through the top thereof. The water from the piping 5 circulates upwardly through the primary heater and absorbs the heat from the burner, the heated water passing through the outlet-pipe 7 and through the pipe 8 to the distributing-piping 9 and to the source of consumption. YVhen no water is consumed from .the distributing-piping 9, the heated water passes through the openings 10 10 at the upper end of the pipe-section 8 and is delivered at the upper part of the storage-tank, from where it is later drawn upon opening of outlets connected with the di.s-.

tributing-piping. It will be noticed that the pipe-section 8 is of greater diameter than the piping 7 leading thereto from the primary heater. The pipe 8 therefore acts as a reservoir or storage-compartment, particularly when the heated water is used immediately upon lighting of the burner. The pipe 7 being reduced impedes the flow of water thereto, and thus the water supplied to the primary heater is caused to linger more or less therein to be more thoroughly heated before arriving in the section 8. Furthermore, the pipe 8 acting as a reservoir prevents the sudden withdrawal of all the hot water through the distributing-pipe 9, which is also of less diameter than this storage-pipe. In heaters of this class heretofore the outlet-pipe from the primary heater was of'the same diameter throughout, and the water-flow was not sufficiently impeded to allow rapid enough heating thereof to supply the primary demand. The primary heater 4, with this arrangement of outlet-piping, forms a very efficient quick heating appliance independent of the storage-tank and other apparatus.

The inlet-pipe 5 is preferably extended a distance upwardly in the tank. place, this prevents sediment or dirt from entering the pipe 5 and assists in the quick heating of the water, as the water entering the pipe is taken from near the top and much warmer than if taken from the bottom of the tank. The inlet-pipe 6 also is extended below the top of the pipe 5 to prevent the cold water therefrom from immediately entering the pipe 5.

The residual heat and gases from the burner pass through flues 1 1, which extend from the combustion-chamber upwardly through the interior of the tank and opening through the top thereof. To prevent the cold water at the bottom of the tank from absorbing the heat of the hot water in the pipe 8, these fines are arranged to form a protective jacket or wall about the pipe 8, and to further shut out the cold water I provide a pipe or shell 12, which surrounds the lower part of the fines and the pipe 8. The heat passing through the flues is thus confined and directed toward the lower art of the pipe 8, and the nick heating of the water is thereby great y facilitated. Any heat left in the fiues after passage through the shell 12 is conveyed to the water at the upper part of the tank, and thus by this arrangement of piping, fines, and protective shell the available heat is "all In the first i ployed.

confined and directed in such a manner as to produce the most rapid efficient heating of the water.

As best shown in Figs. 4 and 5, the primary heater consists of an outer frame and an inner frame. The outer frame consists of upper and lower annular flat heater-sections l3 and 14, connected by pipes or passageways 15, which are threaded into the lower and upper walls, respectively, of the upper and lower sections. Any number of such connecting-pipes or passage-ways maybe em- Through the interior of each passage-way and through the annular sections fiues 16 16 are arranged, these flues being secured to the upper and lower walls, respectively, of the upper and lower annular sections, special bushings 17, such as shown in Figs. 6 and 7, being employed and provided with outer threads for engaging the wall of the upper section and with inner threads for engaging the threaded upper ends of the flues. The inner heater-frame consists of the upper and lower annular heater-sections 18 and 19, arranged concentric with the corresponding sections of the outer heater-frame to leave annular passage-ways and 21. The lower and upper walls, respectively, of these sections 18 and 19 are connected by the pipes 22, through which pass the fines 23 connected to the sections in a similar manner as in the outer heater-frame sections. The inlet-pipe 5 connects with the lower outer annular sec tion 14, and from a diametrically opposite point the connecting-pipe 24 connects with the lower inner annular section 19, thus causing the water to circulate entirely through the lower section before being admitted to the inner heater-frame. The water from the lower sections passes upwardly through the pipes 15 and 22 and circulates through the upper annular sections and between the sections through a connection 24 and from the center of the inner upper section passes upwardly through the piping 7 and 8 to they distributing-pipin or to the upper part of the storage tank. The heat from the burner 3 passes upwardly through the fines 16 and 23, through the annular passage-ways 21 and 20, and through the inner passage-way 25* of the lower inner section, some of the heat also passing around the outer edge of the lower section. Thus the heat is caused to circulate and to be directed against the entire exterior of all the pipes and through the flues to the water passing through the pipes, and a very rapid heating is assured. To retard the flow of water through the pipes 15 and 22, retarding means, such as spiraled wires 26, may be arranged about each flue. These wires cause agitation and spiral circulation of the water through the pipe, the water being thus more readily adapted to absorb a great amount of heat in a very short time. The residual heat from the primary heater passes upwardly through the fiues 11 and is confined, as before 1 described, to superheat the water in pipe 8 and at the upper part of the boiler.

A hot-water heating arrangement of this construction is very inexpensive, as it may substantially be built up of ordinary gas-piping, the only special parts being the annular heater-sections, the arrangement of the parts and the retarding and deflecting means employed causing a more e'fficient and rapid heating of the water than any heating devices heretofore employed.
