UNITED STATES PATENT OFFICE;

IMPROVEMENT 1N COPPERBQILERS.
Specification forming part of Letters Patent No.-39,Sl,'dated September 15, 1863.
the following is stun, clear, and exact de scription of the same'fleference being had to the accompanying drawings, makin g a part of this specification, in which-- Figure 1 is a longitudinal central section of a heater constructed according to my invention, m w, Fig.2, indicating the plane of section; Fig. 2, an external view of the same.
'Similar letters of reference indicate -corre-. sponding parts in the two figures This inventionrelates to an improvement in the construction of copper water-heaters, such as are applied to or connected wit h cooking ranges and stoves. All copper heaters heretofore made have been constructed with compositionvor co per heads, or ends, and fastenedto the cylin r or body of the heater by the copper beingtu'rned over these heads or ends, and made water-tighthy the use of soft. solder, and the heater becoming sometimes intensely hot and then'cooling off, expansion and-contraction occur ta such a degree that the soft solder and copper not yielding or expanding alike causes the 'softsolder to yield or peel off, and the heater-thereby hecomes leaky and unfit for use.
My invention and improvement consist in so constructing the heater that the two ends or heads are entirely brazed in, as are also the copper heater, which body is of cylindrical form, and is connected at its edges by brazing, as shown at a, Fig. 2.
B B represent the end pieces of the heater, which',may. be of dome shape. These end pieces are connected to'the body A by. braz- -iug, as shown at b, Fig. 2. The upper end piece, B, has the cold and hot water pipes G C- attached to it in the usual way. The pipe D, at the bottom or lower end piece, 13 is attached in a novel way, as follows: The end piece B has a large circular hole, 0, made in it, around which hole there is-a pendent flange, d, having a screw cut on its exterior to admit of a cap, E,
being screwed upon it". This cap E is provided with a pendent tube, e, on which a box or socket,F is, screwed, which; secures the pipe-D to the tube e, as shown clearly in Fig. 1. This arrangement of the cap-E and pipe D is the essential feature of: the invention, for by it I am enabled to'secure the ends of the heater to the body by means of brazing.
Brazing, as is well known to coppersu -iths and metal-workers generally, can onlybe erformed at quiteja high heat, which 0 the copper, and renders it necessary. to olish the same after the operation of braflzing has been performed. This polishing, or plaiiishin g, as itis technical] y termed is accomplished by hammering, and in order to effect this it-is necessary to introduce within the heater an instrument to serve the office of an anvil on which to pound the copper. The hole cin the lower end piece, B, admits of this,..-and after the brazing process is accomplishe d the hamordinary copper heaters have their end pieces attached or secured to the body or main por' tion by means of soft solder in consequence 0t no plan having been hitherto devised to ad- I mitof the planishing of the finished'heater after brazing.
does'not, of course, oxidize the metal or injure the planished surface.
aving thus described my invention, I
claim as new and desire to, secure by Letters Patent- 3 v 1. As an improved article of manufacture, a copper water-heater constructed in the maner substantially as herein shown and (leseams orjoints of the heater, and also'toplan scribed. ish 0r hammer the same when brazed, thereby 2. The manner by which I produce or manperfecting the heater, as set forth. '1 ufaeture this heater with the application of A. O. BROWNELL. what may be called a double c0i 1pling--to Witnesses: wit, the cap E, tube 6, and socket F-the use of R013. H. LOUDER,
which enables me to completely braze all the M. MrLlvINGsToN.
