GEORGE WILSON AND SAMUEL BERNSTEIN,' OF CHICAGO, ILLINOIS.
SPECIFICATION forming part of Letters Patent IVO. 544,019, dated August 6, 1895..
Application filed May 8, 1894. Serial No. 510,521. (No model.)
To all whom t may concern,.-
Be it known that we, GEORGE VILsON and SAMUEL BERNSTEIN, citizens f the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented a new and useful Improvement in- Water-Heaters, of which the following is a specification.
Our invention relates to an improvement in the class of heaters which'have come to be known in the art as instantaneous water-l heaters' and are designed for heating water while it courses through the apparatus, especially for bath purposes, on merely igniting a suitable burner at the base of the heater and turning into the latter the cold-water supply.
Our present improvement in the features of its general construction partakes of the nature of that set forth in Letters Patent of the United States No. 429,300, granted to Samuel Bernstein, one of the present applicants, on
the 3d day of June, 1890.
The objects of our improvement are to provide for preparatorily warming the water admitted to the apparatus in its course therein to the spraying mechanism, which serves to impinge it in a finely-divided condition upon the heat-imparting surfaces in the heater and which direct it to the discharge, to provide for utilizing the steam generated by the operation of the apparatus to commingle with and exert its deodorizing effect on the products of combustion from the burner, and to improve the construction of the apparatus generally and in matters of detail, the better to adapt it for its rapidheating function.
Referring to the accompanying drawings, Figure l represents our improved Waterheater by a view in vertical central sectional elevation with the supply and outlet pipe details' shown broken. Fig. 2 is a View in elevation of the inner spiral-liangc-carrying shell of the jacket enveloping the heater. Fig. 3 is a plan view of the spraying-head. Fig. 4 is asimilar view of the distributing-head. Fig. 5 is a plan view of the yoke for conducting the water-supply which enters the distributing-head to the spraying-head, and Fig. 6 is a broken view showing the feed-pipe deflector detail. A f
A is the base of the apparatus, preferably of cylindrical shape, formed of sheet metal, and provided with numerous perforations to admit air to the burner B, supported in the base, and whichA may be of the construction represented or of any other suitable construction. As illustrated, the burner comprises an annular. chamber r, supported in horizontal position in the base A and perforated in its upper side, as at x, the opening in the annulus containing an annular burner-head q, communicating with the chamber fr through a threaded coupling r', whichsupports-in its position the head q, the latter being .perforated, as at zo', in its upper side and covered by a perforatedplate p.
The burner B, which forms no part of our invention, being old and therefore not illustrated'in all its minordetails, is adapted for heating by gas as the fuel, and to that end has a pipe o of comparatively-large diameterleading at one end into the annular chamber fr,
the opposite end being in the form of a funnel o', the more readily to draw in air with the gas, which is supplied by the pipe rrz, provided with suitable shut-off-valve mechanism.
vOn the upper edge of the base A is seated a water-jacket C, preferably of the illustrated cylindrical shape as to its body portion, with an expanded base portion m, closed about its lower edge, and a contracted upper end m. The jacket C is formed with two concentric similarly-shaped sheet-metal shells Z and Z', affording the annular space Zi or chamber between them, the course through which, from the point in the base m at which the coldwater supply-pipe la enters the space, is ren- V,dered spiral by a spiral flange Z3, extending about the outer surface of the inner shell Z from near its lower end nearly to the contracted upper end, the spiral` ange extending entirely or nearly across the chamber Z2. The jacket C envelops a vertical cylindrical or tubular sheet-metal shell C', surmounting the central portion of the burner B and containing an upwardly-tapering sheetmetal shell C2, fastened or sealed about its lower flaring edge to the adjacent inner edge of the shell C and surrounded near its upper end by the annular spraying-head D, which seats on an offset or corrugation t', formed in the IOO shell C. The spraying-head is corrugated or serrated, as shown at e o', respectively, about its periphery and central opening to afford numerous small openings. On an annular diaphragm 7L, in which the upper tapering end ofthe shell C2is fastened or sealed, are secured the two hollow legs g (to coincide with openings t in the diaphragm) of a yoke E, the hollow body g of which, and from x o which the legs proceed, supports a disk-shaped baille-plate F for the products of combustion passing through the shell C2, and is connected by a screw-coupling e with an annular distributing-head F, into thelower side of which the contracted end of the jacket C enters, the head F, which thus crowns the water-jacket, having three internal radial branches e', which open into the coupling e.
From the base of the upwardly-flaring wazo ter-chamber G, formed between the shells C and C2, proceeds the outlet-pipe d to a hollow head d, (shown cone-shaped,) and fromn the lower end of which extends the draw-oft pipe d2, provided with a suitable valve; and from the upper end of the head d extends a valvecontrolled pipe d3, through the jacket C into the annular space s between the jacket and shell C', for the products of combustion from the burner-openings at.
The heater is surmounted by a suitably-ornamented cap H.
The operation is as follows: Upon turning on the gas to the burner and lighting it, so that the products of combustion pass upward through the shell C2 and space s, escaping through the cap II,at`ter having imparted their heat to the surrounding surfaces in the mitted from the pipe 7a into the jacket C, be-
40 ing directed therein by a defiector 7a' at the inlet to follow in the direction of the arrow in Fig. 2 the spiral course about the chamber Z2,
whereby itis preparatorily warmed on its way to the distributing-head F, from which it is directed through the branches e and coupling e into the yoke E and bythe legs g of the latter upon the spraying-head D. To
leave the spraying-head, the water must pass through the small openings afforded by the 5o serrations o and e', which direct it in finelydivided condition into thechamber G, wherein it contacts with the surfaces of the intensely-heated shells C and C2, and in coursing down the latter becomes hot. In discharging the hot water when boiling through the pipe d2, the valve in the pipe d3 should be open to admit the steam, which passes with the water from the chamber G into the head d, to
the annular iue or passage s therein to como mingle with the products of combustion and exert its deodorizing effect thereon.
Vile show in Fig. l an extension d4 of' the pipe dprovided with a shut-off Valve and intended to lead to a shower, (not shown,) and to be used with the valves inthe pipes d2 and d3 closed. It may be stated, however, that in practice the apparatus is not intended to be convertible from a shower to a bath-tub-filling device or vice versa, so that when itis to be used for the first-named purpose the head d and pipes d2 and d3 may be omitted, the pipes d4 and d' then being continuous or one and the same pipe, as indicated by dotted lines, and where it is to be used for the lastnamed purpose the pipe d will be omitted.
