CROSS-REFERENCE RELATED TO APPLICATIONS
Not applicable
BACKGROUND
1. Field of Invention
This invention relates to automotive radiator, reservoir, fluid cooling system radiator caps.
2. Description of Prior Art
I have no knowledge of, nor have ever seen anything resembling my invention.

know of nothing in existence of any device that functions as my embodiments relating to automotive cooling system radiators or reservoirs. I have never seen any device in any store selling anything that resembles my invention.
OBJECTS AND ADVANTAGES
Summary, Ramifications, and Scope
Accordingly, some of the objects and advantages of my invention are;
(a) To provide easy loosening and removal of a radiator cap.
(b) To provide easy replacement and tightening of said cap.
(c) To enable persons with less physical attributes, to loosen, remove, replace and tighten said cap.
Note; if a radiator cap is not tightened to the maximum, a large amount of cooling fluid could be lost. This happens quite frequently, resulting in costly repairs.
(d) To provide an embodiment that can accomodate flat type radiator caps and radiator caps mounted with pressure release levers and other release types.
(e) to provide an embodiment that will function in severest of frigid weather conditions.
(f) to provide easy removal and replacement of various gripped shaped radiator caps such as square, circular, eliptical, hexagon, octagon, circular and square caps having protuding edges designed for easy gripping. This includes all other shapes not mentioned in the above.
(g) To provide an embodiment equipped with adjusters that will accomodate various sizes of radiator caps.
(h) To provide an embodiment that is light weight, approximately four ounces.
(i) To provide an embodiment that can be constructed of hardwoods, metals, molded plastics, laminates, combinations of metals and other rigid materials.
(j) To provide an embodiment that will function with radiator caps equipped with pressure release levers.
Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. For example the embodiments of my invention can have other shapes, such as circular, oval trapezoidal, triangular etc.
Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
DESCRIPTION
First Embodiment
FIG. 1A
FIG. 1B
Has no moving parts, will fit a large group of radiator caps, easy to handle, easy to make.
A typical embodiment of the present invention is illustrated in
FIG. 1A
(top view) and
FIG. 2A
(bottom view). The base
10
is hexagon shaped metal 1.56 mm in thickness
18
. The six vertical sides
14
and the metal base
10
are formed from a single piece of metal. The six vertical sides
14
vary in length. The sides measure between 30 mm and 37 mm. The height
18
is 12.5 mm. Open spaces
20
exist between sides. The spaces between the sides
20
also vary. The inside measurements between any two parallel sides
22
are approximately 6.35 mm. The base
10
is connected to a wooden handle
24
with 2 bolts and nuts
26
. The handle
24
is approximately 14 cm long, slightly rounded. This embodiment has no moving parts.
Second Embodiment
FIG.
2
A and
FIG. 2B
This embodiment can be used with more different sizes and shapes than the first embodiment.
The second embodiment FIG.
2
A and
FIG. 2B
structure is identical to the first embodiment FIG.
1
A and
FIG. 1B
except for an added feature. This embodiment is fitted with 3 movable thumb screws
28
size {fraction (10/24)} machine threads. These thumb screws
28
adjusts inwardly and outwardly thru 3 threaded sides, A {fraction (10/24)} machine thread nut
30
is soldered to these sides adjusts inwardly and outwardly thru 3 threaded sides after the holes are drilled.
Third Embodiment
FIG.
3
A and
FIG. 3B
This embodiment can perform to almost any radiator cap made.
This embodiment will function with pressure release levers.
FIG.
3
A and
FIG. 3B
illustrates the top view and bottom view.
A third embodiment of my invention has the same functional mechanical advantages of loosening, removing, replacing and tightening radiator caps as my first and second embodiments. This embodiment is formed from a single piece of metal. The base
32
is of square shaped metal 1.56 mm thick
16
. There are 4 vertical sides. These sides vary in length. The shortest side
34
a
is 3 cm in length. The second shortest side
34
b
is 4 cm in length. The remaining two sides
34
e
are each 5 cm in length.
Sides
34
e
and
34
d
each have tapered corners at the top. The height of the sides
18
are 12.5 mm. the thickness
16
is 1.56 mm. The inside measurements between any two parallel sides
47
is 6.5 cm. A pivotal metal strip
35
is connected to the base
32
adjoining side
34
a
. This strip
35
measures 5 cm in length, 12.5 mm in width, and 1.56 mm in thickness. A nut and bolt
37
is used as a pivotal point connecting
32
and
35
as shown in
FIG. 3A
bottom view. A hole is drilled in
32
and
35
allowing the nut and bolt to connect to the pivot strip and base. The pivot strip
35
has a sweeping moving of approximately 60 degrees. A hole is drilled in sides
34
a
and
34
b
. A nut
30
is soldered to each of these sides. Two thumbscrews
28
are used as adjusters, as shown in
FIG. 3A. A
wooden handle
40
is attached to base
32
with 4 nuts and bolts
41
. The wooden handle
40
has dimensions of 14 cm in length, 3.5 cm in width and 1.56 cm in thickness. The wooden handle
40
has a profile cutout
36
matching the base
32
as shown in FIG.

B. This embodiment will accomodate radiator caps having pressure release levers for a mechanical advantage of loosening, removing, replacing, and tightening radiator caps. My invention will fit almost any size, shape, or form of radiator cap and do the job.
Operation FIG.
1
A and
FIG. 1B
The first embodiment is very easy to use. There are no moving parts. This embodiment is used with regular size flat caps.
FIG. 5
shows a group of flat radiator caps that are equipped on many automobiles. Simply place this embodiment over the radiator cap. Make sure of a snug fit. Using both hands, grip the handle with one hand, hold the base
10
with the other hand. Turn the handle slowly about an eight of a turn in a counter clockwise direction, the radiator cap is now loose. To replace, use reverse procedures. Simply place the radiator cap back on the radiator, place the embodiment on the radiator cap making sure that it fits snugly. With a firm grip, slowly turn the handle clockwise til the radiator cap is tight.
Operation, Second Embodiment, FIG.
