GEORGE M. PATTERSON, OF *FAIRFIELD, MAINE, ASSIGNOR TO RALPH PATTERSON,
OF WATERVILLE, MAINE.
ELECTRICAL WATER-HEATER.
Application filed January 13, 1915, Serial No. 1,940. Renewed February 17, 1916.
T 0 all whom it may concern Be it known that I, Gnonon M. PA'JTER- soN, a citizen of the United States, residing in the town of Fail-field, in the county of Somerset and State of Maine, have invented new and useful Improvements in Electrical ater-Heaters, of which the following is a specification,
My invention relates to improvements in electrically operated liquid heaters.
An important object of the invention is to provide apparatus of the above mentioned character, adapted to permit of the free passage of the liquid to be heated therethrough without unduly retarding the travel, and to impart the maximum heat to the liquid during such travel, whereby the liquid may be heated expeditiously and con tinuously.
A further object of the invention is to provide means of the above mentioned character, which are simple in construction, inexpensive to manufacture, convenient in use, strong and durable.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of apparatus embodying my invention, Fig. 2 is an edge elevation of the same, Fig. 3 is an end elevation of the apparatus, Fig. 4 is a central longitudinal sectional view through the apparatus, Fig. 5 is a longitudinal sectional view taken on line 5 5 of Fig. 1, and, Fig. 6 is a side elevation of the apparatus showing the same connected with a hot water storage tank.
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a main shell or casing, constituting the body portion of the apparatus. This shell or casing is preferably vertically arranged when the apparatus is in use. The shell 10, as shown in Fig. 5gl1as its side walls 11 pro vided at preferably equidistantly spaced intervals with outwardly bulging portions 12, preferably curved in cross section, providing enlarged preferably cylindrical chambers 13. These enlarged preferably cylindrical chambers are connected in series between their ends by ports or passages 14, en

tering them at diametricallyopposite points. The chambers 13 are much longer than the passages 14. As clearly shown in F ig, 4, said passages 14 are reduced in length by partitions 15 and 16.
The numeral 17 designates a cold water inlet, discharging into the lowermost chamber 13, while a hot water outlet 18 leads from the uppermost chamber 13, as shown. The hot water passing through the pipe 18 may beconducted directly to the place of use or may be fed into a hot water storage tank 19, from which it is subsequently withdrawn, it being obvious however that the same constitutes no part of the present in ventlon.
The numeral 20 designates preferably metallic closed heating tubes, preferably concentrically arranged Within the enlarged chambers 13, with their free ends spaced a substantial distance from the adjacent edges of the shell 10, providing passages 21, as shown. Arranged within each of the tubes 20 is a heating resistance coil 22, connected in parallel with feed and return wires 23 and 24, in turn connected with a suitable source of current not shown. The tubes 20 have their opposite ends fitting tightly within screw-threaded screws 23 removably mounted within openings 24 formed in the adjacent edge wall of the shell 10.
The wires 23 and 24 of associated ele ments are preferably inclosed by a cover 25, held in place by screws 26 or the like.
In operation, the cold water entering into the lowermost chamber 13, passes upwardly through the shell 10 and finally discharges in a. heated condition through the pipe 18. Upon entering each chamber 13, the water engages the curved surface of the heating tube 20 therein and is made to flow in a plurality of streams about the side and end of the tube, whereby it comes in contact with the maximum heating area. The cross sectional area of the space between each heat ing tube and the inner wall of the chamber 13 is preferably greater than that of the passage or passages 14, whereby the flow of the water is not unduly retarded.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit or" the'invention or the scope of the subjoined claims.
Having thus described the invention, I claim 1. In a liquid heater of the character described, a shell having its side walls bulging outwardh at spaced intervals providing enlarged chambers which are connected in series by passages, heating tubes extending into the enlarged chambers, and electrical heating devices arranged within the heating tubes. substantially as described.
2. In a liquid heater ot the character de scribed, a shell having its side walls provided at spaced intervals with curved outwardly bulg. ng portions providing substantially cvlindrical enlarged chambers having communication with each other, substantially cylindrical heating tubes arranged substantially concentric within the heating chambers, heating coils arrangev'l within the tubes. and a circuit connected with the coils.
3. In a liquid heater of the character de scribed, a shell having its side walls pro-' vided at spaced intervals with curved outwardly bulging portions providing substantially cylindrical enlarged chambers, trans verse partitions arranged within the shell between the chambers with their ends spaced tor affording contracted passages establishing communication between the chambers, heating tubes connected with one wall ()1 the shell and extending into the chambers with their free ends spaced from the opposite wall of the shell, heating coils arranged within the tubes, and means to supply current to the coils.
4-. In a liquid heater of the character described, a shell having one wall provided with spaced screw-threaded openings, screw threaded sleeves adapted to be inserted within the openings, heating tubes carried by the sleeves and extending into the shell, and heating coils arranged within the tubes.
In a liquid heater of the character described, a shell having one wall provided with spaced screw-threaded openings, screwthreaded sleeves adapted to be inserted within the openings and accessible from the exterior of the shell, heating tubes arranged within the shell and engaging the sleeves, coils disposed within the tubes, wires arranged exteriorly or the tubes adjacent the sleeves, and connected with the coils, and a cover inclosing the apertured wall of the shell.
