Specification of Letters Patent.
Patented May 18, 1909.
Application filed January 4, 1906. SerialNo.-294,518.
To all whom it may concern:
Be it known that I, PERLE T. GLAss, a citizen of the United States, residing at Corona,
State of California, have invented new and useful Improvements in Solar lVater-Heaters, of which thefollowing is a specification.
It is one of the objects of this invention-to provide .a solar water heater of cheap and simple construction which will have a maxi- .mum capacity for heating water,.with a given size of heater, and to utilize the rays of the sun for such purpose throughout a maximum length of time.
Another object is to so construct the water heater as to avoid liability of breakage from hail storms.
Another object is to so construct the a pliance as to equalize the distribution of the water through a series of heating tanks in the simplest and most eflective manner.
The accompanying drawings illustrate the invention.
Figure 1 is a plan of a water heater embodying the invention. Fi 2 is aperspective view of the same insta ed for use on a roof, one wall being broken away for clearness of illustration. Fig. 3 is a view from the left of Fig. 2 omitting the lower left hand wall shown in that view, the wall which is omitted from Fig. 2 being shown in Fig. 3. Fig. 4 is a detail of the sash on an enlarged scale. Fig. 5 is an enlarged fragmental detail of the box with its asbestos and burnished bright metal linings.
1 is a case which is a box closed at the sides and bottom and open at the top.
.the cavity 3, in
2 is a transparent cover closing the case 1.
at the top and excluding external air from which are located a plurality of pressure tanks 4.
5 is a supply pipe, and 6 a discharge pipe. The supply pipe 5 is connected in series wit pressure tanks 4 at one end thereof by niples 7. The dischar e pipe 6 is connected 1n like manner with t e opposite ends of the tank by nipples 8.
9 designates end pieces, 10 sash bars, and 11 transparent plates of glass forming a cover for the top of the case. The cover may be said to be corrugated, each side of the corrugations being formed by a transparent pane 11.
The upper portions of the pressure tanks 4 are chambered in the inside angles of the corrugations respectively as will clearly-be seen by referring to Fig. 3. The purpose of this construction is to admit to the outside of the'pressure tanks a maximum amount of the suns rays and to make possible the interposition between the tanks and the sun, of as few sash bars as possible.
By the construction shown, the ridge sash bars 10, may be made of metal or other suitable strong material, and the valley sash bars 10 are located at a point where they do not obstruct the suns rays from reaching the tanks.
12 designates the corrugated bottom of the case, the corrugations thereof may be of any suitable form or size.
In practice the solar water heater will be mounted aslant upon a roof 13 in the usual manner and when the sun rises its rays will have ready access to the tanks on account of the slanting transparent sides which chamber the u per portions of the tanks. Any rays whic esca e the tanks will reach the burnished metal lining 12 and be reflected back toward the tanks.
14 designates asbestos arranged between the wooden bottom 15 of the case and the corrugated metal bottom 12 thereof, thus, to prevent the escape of the heat through the ottom of the box. The walls of the box are similarly provided with the asbestos, and refleeting metal linings 16.
The elongated pressure tanks, 4, 4", etc. extend in a row, the length of each tank lying transverse to said row. .The supply pipe 5 leads to the tank 4 at one end of the row and communicates with all the tank ends at the lower side of the row. The discharge pipe 6 communicates first with tank 4 at the top end thereof,and also upper ends of the other tanks. I
The supply pipe 5 is connected in series with the tanks, beginning with a tank at the first of the series as 4, and ending with the last of the series as 4' connectin intermediately with the tanks 4 and 4, w 'le the discharge pipe opens first from the tank 4 and tanks, the amount drawn advantageous system of iping is new in the art of constructing solar eaters.
The lining of the box or case of the Water heater is provided with a reflecting face, formed by the bright burnished metal 12, and With-a heat insulating lining formed of the asbestos 14 thereby converging and refleeting the heat to the best advantage. What I claim is:
1. A solar Water-heater rovided with a corrugated burnished metal ott0m, a corrugated transparent glass top, and tanks chamered in the corrugations of the to the corrugations of the top beingpara-lle With the open at the top, an asbestos lining for the case,'a corrugated metal bottom in the case, a corru ated transparent top for the case, and tan rs chambered in the corrugations of the top.
4. A solar Water-heater comprising a case, a lining of noneonducting material for the case, a corrugated metal bottom for the case,
a corrugated glass top for the case, tanks chambered in the corrugations of the top, a
supply-pipe connected to the lower ends of the tan and a discharge-pipe connected to the upper ends of the tanks.
In testimony whereof, I have hereunto set my hand at Los Angeles, California this 27th day of December 1905.
