pESCRIPTION ~F THE PREFERRED EMBODIMENT
Referring now to the drawings, in which similar or corresponding parts are identified with the same reference numeral, and more particularly to Figure 1, the salt water power source and lantern of the present invention is designated generally at 10 and includes a housing 12 having a carrying strap 14 removably and adjustably connected thereto, to permit transport of the power source in lantern 10.
Because the apparatus is configured as a lantern in the drawings, the apparatus will be described as a lantern throughout, although it can be used as a power source to power radios and other apparatus as well. ' The "lantern" description is merely intended for ease of description.
Housing 12 has a hollow interior cavity 16 enclosed by a front wall 1$, rear wall 20, end walis 22 and 24, and top and bottom walls 26 and 28 respectively.
Referring now to Figure 2, it can be seen that bottom wall 28 of housing 12 also forms the top wall of a base unit 30. Base unit 30 has a side wall 32 which projects outwardly and downwardly from the front rear and end walls 18, 20, 22, and 24 of housing 12, to support the bottom wall 28 above the ground. A platform 34 may be connected to base unit 30 to form a storage cavity 36 under base unit 30.
Platform 36 is preferably connected with a pair of hook members 38 at one end thereof joumafed through receiving apertures 40 (shown in Figure 4), and a clasp 42 at the opposite end to grip a separate hook member 44 on the platform.
As shown in Figure 2, four cylindrical hollow tubes 46, 48, 50 and 52 extend between the top and bottom walls 26 and 28 of housing 12, to form sealed cavities 46a, 48a, 50a and 52a respectively. Each tube 4fi, 48, 50 and 52 is preferably mounted on a circular disk-shaped platform 46b, 48b, 50b and 52b respectively on bottom wall 28.
Referring now to Figure 4, tube 46 is shown in more detail. A threaded metal stud projects upwardly through platform 46b and is connected to a threaded aperture 56 in the lower end of a magnesium alloy rod 58. Thus, rod 58 will extend upwardly centrally within cavity 46a 'of tube 46. Tube 46 has a generally rectangular opening or window 60 formed therein which is covered by an arcuate plate fit to seal the tube 46.
Plate 62 is curved to the same radius as tube 46, so that the surface of plate 62 is spaced a constant distance from rod 58. A terminal 64 is mounted on plate 62, and has a wire 66 electrically connected thereto. Similarly, stud 54 has a wire 68 connected to a lower end of the stud and extending to a terminal 70 adjacent platform 46b. A
wire 72 connected to terminal 70 extends to one terminal 74 of an electrical jack 76, as shown in Figure 3. Plate 62 is formed of an electrically conductive material and acts as a cathode when salt water is poured within cavity 46a of tube 4fi. Rod 58 acts as an anode and is formed of a magnesium alloy material which will react to the salt water solution so as to give us electrons, which flow to plate 62 to form an electric current.
Referring once again to Figure 2, each of tubes 48, 50 and 52 also include an anode rod 58, and a cathode plate 62 in the same fashion as tube 46. Thus, tubes 46, 48, 50 and 52 form power cells for producing an electrical current when salt water is introduced within each of the tubes.
Referring now to Figure 3, an electrical diagram is shown wherein the power cells formed by tubes 46, 4$, 50 and 52 are electrically connected in series.
As described above, one wire 72 from terminal 70 is connected to one terminal 74 of an electrical jack 76. A second terminal 78 on jack 76 is electrically connected to one terminal 80 on an onloff switch 82. A second terminal $4 on onloff switch 82 is electrically connected to a terminal 86 on an electrical starter board 88. A
second terminal 90 on starter board 88 is then electrically connected to a termin2~l 92 on the cathode plate 62 of power cell tube 52, to thereby complete the circuit. tn this way, operation of onloff switch 82 will close the electrical circuit of power cells 46, 48, 50 and 52 in series with jack 76 and starter board 88. Starter beard 88 preferably includes a pair of leads 94 and 96 which are connected to a socket 98 for an electrical lamp 100 (shown in Figures 1 and 2). Starter board 88 may be utilized to start a fluorescent lamp fixture, or other electrical device, and may be eliminated if it is merely desired to directly connect the power source to socket 98. Similarly, jack 76 permits distribution of electrical power from power cells 46, 48, 50 and 52 to other electrical apparatus through conventional plug inserted within jack 76.
Referring once again to 1=figure 2, it can be seen that each of power cell tubes 46, 48, 50 and 52 have an opening 102 formed in their upper ends, permitting the introduction of salt water into the cavities 46a, 48a, 50a and 52a. A set of removable caps 104, as shown in Figure 1, are installed on each opening to seal the opening and maintain the liquid within each of the power cells.
A depression 106 is formed in the front and top walls of housing 12, within which lamp 100 is installed. A reflective plate or coating 108 may be installed within depression 106 to reflect light from tamp 100. Obviously, the location, size and orientation of the depression 106 and lamp 100 rnay be altered without departing from the spirit of the invention.
In the preferred embodiment of the invention, the magnesium alloy rods are approximately 2 1/2 inches long and 518 inch in diameter. Each cathode plate is approximately 1 inch by 1 1I2 inches and 1116 inch thick. When the power cells areas provided with a salt water solution, approximately 4.8 volts are provided in a no load condition, and 4 volts in a loaded condition, and produce 500-800 milliamperes of electricity. Typical life of the unit is 30 hours at 500 milliamps. The salt water solution must then be replaced. Each of the anodes should be replaced approximately every 60 hours, and the anode and cathode are preferably scrubbed clean between refiNs of salt water solution in the power cells.
Whereas the invention has been shown and described in connection with the preferred embodiment thereof, many modiFcations, substitutions and additions may be made which are within the intended broad scope of the appended claims.
Plate 62 is curved to the same radius as tube 46, so that the surface of plate 62 is spaced a constant distance from rod 58. A terminal 64 is mounted on plate 62, and has a wire 66 electrically connected thereto. Similarly, stud 54 has a wire 68 connected to a lower end of the stud and extending to a terminal 70 adjacent platform 46b. A
wire 72 connected to terminal 70 extends to one terminal 74 of an electrical jack 76, as shown in Figure 3. Plate 62 is formed of an electrically conductive material and acts as a cathode when salt water is poured within cavity 46a of tube 4fi. Rod 58 acts as an anode and is formed of a magnesium alloy material which will react to the salt water solution so as to give us electrons, which flow to plate 62 to form an electric current.
Referring once again to Figure 2, each of tubes 48, 50 and 52 also include an anode rod 58, and a cathode plate 62 in the same fashion as tube 46. Thus, tubes 46, 48, 50 and 52 form power cells for producing an electrical current when salt water is introduced within each of the tubes.
Referring now to Figure 3, an electrical diagram is shown wherein the power cells formed by tubes 46, 4$, 50 and 52 are electrically connected in series.
As described above, one wire 72 from terminal 70 is connected to one terminal 74 of an electrical jack 76. A second terminal 78 on jack 76 is electrically connected to one terminal 80 on an onloff switch 82. A second terminal $4 on onloff switch 82 is electrically connected to a terminal 86 on an electrical starter board 88. A
second terminal 90 on starter board 88 is then electrically connected to a termin2~l 92 on the cathode plate 62 of power cell tube 52, to thereby complete the circuit. tn this way, operation of onloff switch 82 will close the electrical circuit of power cells 46, 48, 50 and 52 in series with jack 76 and starter board 88. Starter beard 88 preferably includes a pair of leads 94 and 96 which are connected to a socket 98 for an electrical lamp 100 (shown in Figures 1 and 2). Starter board 88 may be utilized to start a fluorescent lamp fixture, or other electrical device, and may be eliminated if it is merely desired to directly connect the power source to socket 98. Similarly, jack 76 permits distribution of electrical power from power cells 46, 48, 50 and 52 to other electrical apparatus through conventional plug inserted within jack 76.
Referring once again to 1=figure 2, it can be seen that each of power cell tubes 46, 48, 50 and 52 have an opening 102 formed in their upper ends, permitting the introduction of salt water into the cavities 46a, 48a, 50a and 52a. A set of removable caps 104, as shown in Figure 1, are installed on each opening to seal the opening and maintain the liquid within each of the power cells.
A depression 106 is formed in the front and top walls of housing 12, within which lamp 100 is installed. A reflective plate or coating 108 may be installed within depression 106 to reflect light from tamp 100. Obviously, the location, size and orientation of the depression 106 and lamp 100 rnay be altered without departing from the spirit of the invention.
In the preferred embodiment of the invention, the magnesium alloy rods are approximately 2 1/2 inches long and 518 inch in diameter.
