G. F. SCHWARTZ WATER HEATER.
Patented Dec. J, 191%).
APPLICATION FILED SEPT-4.1918.
v ATTORNEY nurrnn sma ts .rarnnr onrrcn.
GERI-IAR-D'T F. SCHWARTZ, ST. LOUIS, MTSSOURI.
To all whom it may concern:
Be it known that I, GERHARDT F. SCHWARTZ, a citizen of the United States, and a resident of St. Louis, Missouri,have' invented certain new and useful Improvements in Water-Heaters, of which the following is a specification. V
My present invention has for its object to 'improve water heaters for the purpose of pan forming part of this apparatus;
Fig. 4: a vertical section on line 44 of F ig. 3; and
Fig. 5 a top plan view of the second com; bustion burner and its water jacket substantially on line 5-5 of Fig. 1.
lVater froma suitable source of supply is admitted through the pipe extending downwardly through. a bushing 11, fitted into the top or cover 12 of the tank proper, havinga cylindrical metallic wall 13 preferably surrounded by a jacket 14 of asbestos or other suitable heat retaining material;
' thatjs to say, a poor conductor ofiheat.
Into the lower end of the pipe 10*entends the upper end of a thermostatic tube 15 of copper containing a porcelain rod, said tube passing through a bushing 16 in the annular bottom 17 of the tank, and having its lower end" connected with a thermostat 18, the
. detail construction of which forms the subject-matter of another application. It will suffice to say here that the fuel gas enters the thermostat at 19, and that this thermostat contains a valve controlling the passage of said gas to the pipes 20 and 21, the latter having a pilot light, while the former eX tends into the air tube or mixing tube 22,
open to the surrounding air at the bottom,
and leadingto a double combustion burner of acharacter set forth 1n other appllcations for patents previously filed by me, for in-.
stance, Serial No. 58,927, filed October 30th,
WATER-HEATER.
Specification of Letters Patent.
Patented Dec. 9, 1919.
Application filed September 4, 1918. Serial No. 252,507.
1915. The said burner is composed of a primary burner 23, having annular or slit like substantially horizontal outlets, by which the flame is directed against a surrounding vertical wall 24, and above said primary burner is located the secondary burner plate provided with openings 26, and extended at its periphery to form the top wall of a water acket 27 surrounding said wall 24. The jacket is provided with a partition 28, and at one side of said partition a pipe 29 comnnmicating with the water jacket 27 extends upwardly to connect with a union 29 and with a vertical pipe 29 reaching from the bottom 17 of the tank to a point near the top of saidtank, through which also extends a pipe 30 for conducting the hot water to the place of use, said pipe 30 being preferably in line with'the pipe 29".
Connections may be made to a water back of well-known construction by means of a tube or nipple 31 located about half way between the top and bottom of the tank, and another nipple 32 located near the bottom of the tank. The nipple 32 has two connections, one of them indicated at 33 leads to the jacket 27; the other, indicated at 34' (and preferably made in two portions connected by a union 3%) leads to a nipple 35 at the lower portion of the tank. The burner with its jacket is substantially ofthe same construction as in Figs. 4 and 5 of my application Serial No. 58,927 above referred to, but instead of harin the connections 29, 33 extending upwardly at opposite sides of i the partition 28, one of the said connections,
to wit, the pipe 3 3. is arranged horizontally and enters the vertical wall of the acket 27 Into the central opening of the tank bottom 17 is fitted a flue 36 )referably corru gated as shown. and this uc together with the adjacent edge of the tank bottom is fitted into an annular rhannel 37 of a condensation pan. which in addition to said annular channel co'ul n'ises a central pan or dish 38 spaced from said channel so as to provide an annular opening 39, the two parts of the pan being suitabl connected as by lugs 40. Into the central portion 38 of the coruileusatiou pan is lifted another flue -11 preferably also corrugated, said flue being of considcrably smaller diameter than the flue 36, So that an annular heating chamber 42 will be formed between them. The condensation pan closes the bottom of the central flue 4-1, which latter extends upwardly through the top 12 of the tank and is open for the discharge of the combustion products.
third of its height only, and is provided with a top plate. 43 to close the heating chamber 42. Immediately below the said is provided with a base 47 surrounding the burner, and said base is preferably provided with two doors, one of them indicated at 4:8 to facilitate'access to the burner, and the other 49 provided with a notch at one of its edges or corners for the passage of the pipe 33. v
It will be understood that the combustion at the primary burner will heat the water in the jacket 27, which water is supplied through the pipe 33. The water thus heated passes from the jacket 27 into the heater tank,-through the pipe 29. The water supplied to the acket 27 through the pipe 33 comes partly from --the water back, and partly from the lower portion of the tank through themipple 35, or all from the lower portion of the tank if no waterback connections are made.
The secondary combustion takes place above the burner plate 25, and the combustion products are projected against the bottom 17 of the tank, and against the condensation pan, and are compelled to pass through the annular channel 39 between the central portion 38'and the annular channel 37 of the condensation pan. The combustion gases thus reach the heating chamber 42, the outer wall 36 of which forms a large surface in contact with the water at the lower portion of the tank, that is to. say, "in contact with the coldest part of the'waterz- The combustion gases rise in the chamber 42 along the said wall 36, and pass through the opening 44 into the central flIue a1. In the upper portion of the flue 41, which upper portion is incontact with the water contained in the tank, the combustion gases are retarded by the spiral baffle 45, so as to cause them to give up most of their remaining heat to the water contained in the tank. Any matter condensed from the combustion g: ses within the chamber 42 will flow down partly along the inner surface of the flue 36, into the annular chamber 37 of the condensation pan and partly'along the outer surface of the flueel into the central portion 38 of said pan. Any matter condensed The flue 36 does not extend to 3 the top of the tank, but say to about oneneat-pm within-the flue 41 will flowalong the inner tion 38 of the condensation pan. v The condensation pan may be held against surface of said flue into the central per .the lower edgesof the flues36, 41 by a post or leg 50 interposed loosely between the second combustion burner top '25 and said pan, so that the pan can be removed readily for cleaning and also to. give access to the flues when desired.
The burner or water-heating member located beneath the tank, can be detached J readily for cleaning or other-purposes, by
