Abstract
Abstract The solar fluid heater has a frame and a solar collector for collecting and concentrating solar energy movably mounted on the frame. An inclination adjustment system is attached to the frame for rotating the solar collector for different inclinations of the earth relative to the sun, and a solar tracking system moves the solar collector in a different direction on the frame during daylight hours responsive to the flow of liquid from a reservoir mounted thereon to track the sun during daylight hours.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
137 words
A solar fluid heater comprising in combination: a frame having a base and a movable portion; solar collector means for collecting and concentrating solar energy, said solar collector means being movably attached to said frame; inclination adjustment means for adjusting said solar collector means for different inclinations of the earth relative to the sun, said inclination adjustment means being attached between said frame base and said movable portion; solar tracking means for moving said solar collector means on said frame during daylight hours responsive to the displacement of a liquid from one reservoir mounted on said collector means whereby said solar collector means may be directed to follow the sun; and flow control means for controlling the gravity flow of liquid from said one liquid reservoir to adjust the rate of movement of said solar collector means.
Claim 2
Dependent Claim
137 words
A solar fluid heater comprising in combination: a frame having a base and a movable portion; solar collector means for collecting and concentrating solar energy, said solar collector means being movably attached to said frame; inclination adjustment means for adjusting said solar collector means for different inclinations of the earth relative to the sun, said inclination adjustment means being attached between said frame base and said movable portion; solar tracking means for moving said solar collector means on said frame during daylight hours responsive to the displacement of a liquid from one reservoir mounted on said collector means whereby said solar collector means may be directed to follow the sun; and flow control means for controlling the gravity flow of liquid from said one liquid reservoir to adjust the rate of movement of said solar collector means.
Claim 3
Dependent Claim
41 words
A solar heater in accordance with claim 1 in which said solar tracking means includes means moving said solar collector means on said frame during daylight hours responsive to the flow of a liquid from one reservoir to a second reservoir.
Claim 4
Dependent Claim
34 words
The solar heater in accordance with claim 2, in which said solar tracking means controls the movement of said solar collector means responsive to the flow of a liquid through a plurality of reservoirs.
Claim 5
Dependent Claim
18 words
The solar heater in accordance with claim 3, in which said first reservoir is a refillable, vented reservoir.
Claim 6
Dependent Claim
33 words
The solar heater in accordance with claim 4, in which said inclination adjustment means includes means connected between said frame base and movable portion for adjusting said movable portion relative to said base.
Claim 7
Dependent Claim
44 words
The apparatus in accordance with claim 5, in which said means for adjusting the position of said movable frame portion to said base portion includes a turnbuckle connected to said base frame portion and said rotable frame portion for rotating said movable frame portion.
Claim 8
Dependent Claim
29 words
The apparatus in accordance with claim 6, in which said movable frame portion includes at least one arcuate frame member rotably positioned on said base frame for rotation thereon.
Claim 9
Dependent Claim
30 words
The apparatus in accordance with claim 7, in which said movable frame portion is connected to said base frame portion by supporting frame arms supporting a pair of support pins.
Claim 10
Dependent Claim
21 words
The apparatus in accordance with claim 8, in which said solar collector means includes a parabolic solar collector having curved ends.
Claim 11
Dependent Claim
33 words
The solar heater in accordance with claim 9, in which said solar collector means includes coiled tubing mounted in the bottom of said parabolic collector surrounding the focal point of the parabolic collector.
Claim 12
Dependent Claim
30 words
The apparatus in accordance with claim 10, in which a reflective center pipe is mounted in the middle of the coiled tubing along the focal point of said solar collector.
Claim 13
Dependent Claim
24 words
The apparatus in accordance with claim 11, in which the output from said coil passes through an output pipe passing through said center pipe.
Claim 14
Dependent Claim
18 words
The apparatus in accordance with claim 12, in which said solar collector means has a transparent cover thereover.
Claim 15
Dependent Claim
72 words
The apparatus in accordance with claim 13, in which a flexible water line is connected to one end of said coil and a flexible output line is connected to said pipe passing through said center pipe so that water may flow through said coils, be heated in said solar collector means and pass out of said solar collector means while said solar collector means is following a path to face the sun.
