Total Claims: 19
Claim 1
Independent Claim
276 words
A combination for monitoring and filling a reservoir with fluid comprising: (a) a circular filler assembly having distal and proximal ends permanently connected to said reservoir through said distal end; (b) mean for semi-permanent insertion at said proximal end of said filler into said assembly for forming a passageway to allow fluid to be transferred into said reservoir; (c) movable and flexible means located within said passageway to monitor the fluid level within said reservoir, said movable and flexible means further including means for floating upon the surface of said fluid; (d) indicator means utilizing contrasting first and second colors for displaying an amount of fluid to maintain said reservoir in a filled level; (e) said indicator means being located for easy viewing comprising first and second member: wherein said first member is attached to said movable and flexible means, and said second member being positioned concentrically upon said insertion means for slidable engagement with said first member; (f) said indicator means displaying said first color only by means of said first member when said reservoir is in a filled condition, and said indicator means displaying said first color in contrasting arrangement with said second color by means of the slidable engagement of said second member with respect to said first member to indicate a partial depletion of fluid from said reservoir; and (g) the length of travel of said movable means through said floating means corresponding to an amount of display of said second color with respect to said first color in accordance with a level/volume ratio of said reservoir, and a greater first and second color contrast indicating a greater depletion of said fluid.
Claim 2
Dependent Claim
276 words
A combination for monitoring and filling a reservoir with fluid comprising: (a) a circular filler assembly having distal and proximal ends permanently connected to said reservoir through said distal end; (b) mean for semi-permanent insertion at said proximal end of said filler into said assembly for forming a passageway to allow fluid to be transferred into said reservoir; (c) movable and flexible means located within said passageway to monitor the fluid level within said reservoir, said movable and flexible means further including means for floating upon the surface of said fluid; (d) indicator means utilizing contrasting first and second colors for displaying an amount of fluid to maintain said reservoir in a filled level; (e) said indicator means being located for easy viewing comprising first and second member: wherein said first member is attached to said movable and flexible means, and said second member being positioned concentrically upon said insertion means for slidable engagement with said first member; (f) said indicator means displaying said first color only by means of said first member when said reservoir is in a filled condition, and said indicator means displaying said first color in contrasting arrangement with said second color by means of the slidable engagement of said second member with respect to said first member to indicate a partial depletion of fluid from said reservoir; and (g) the length of travel of said movable means through said floating means corresponding to an amount of display of said second color with respect to said first color in accordance with a level/volume ratio of said reservoir, and a greater first and second color contrast indicating a greater depletion of said fluid.
Claim 3
Dependent Claim
20 words
The combination in accordance with claim 1 wherein said insertion means is funnel-shaped at the proximal end of said filler.
Claim 4
Dependent Claim
20 words
The combination in accordance with claim 1 wherein said first member is of a smaller diameter than said second member.
Claim 5
Dependent Claim
53 words
The combination in accordance with claim 3 wherein the second member of said indicator means is located upon said insertion means and is swivable thereon with respect to said first member, said first member being movable in a vertical direction in accordance with a positioning of said floating means upon the reservoir fluid.
Claim 6
Dependent Claim
49 words
The combination in accordance with claim 3 wherein (a) more than one-half of said second cylindrical member of said indicator means as measured by its diameter is formed from a transparent material; and (b) the remainder of said second member is made opaque by means of said second color.
Claim 7
Dependent Claim
40 words
The combination in accordance with claim 3 wherein (a) said first cylindrical member is formed such that said first color is formed upon its exterior surface; and (b) said first and second contrasting colors being observable through said transparent material.
Claim 8
Dependent Claim
47 words
The combination in accordance with claim 6 wherein said insertion means includes a hinged lid located upon an uppermost portion of said passageway for maintaining the fluid in said reservoir in a dust-free condition, as well as for allowing fluid to be readily added to said reservoir.
Claim 9
Dependent Claim
26 words
The combination in accordance with claim 7 wherein the amount of vertical travel of said floating means is determined by a level/volume ratio of said reservoir.
Claim 10
Dependent Claim
28 words
The combination in accordance with claim 8 wherein maximum travel of said floating means is determined by an enclosing member located at a lowermost portion of said passageway.
Claim 11

Claim 14
Dependent Claim
206 words
A combination for monitoring and filling a reservoir with fluid comprising: (a) a filler assembly having distal and proximal ends connected to said reservoir through said distal end, and said proximal end having an entrance for adding fluid to the reservoir; (b) means juxtaposed to said entrance for alternatively blocking foreign matter or allowing fluid to be added to said reservoir; (c) a monitor assembly for determining the fluid level within said reservoir located upon said juxtaposed means, and comprising a rotatable member in combination with a vertical moving member which rises or falls in accordance with a level/volume ratio of said reservoir; (d) said monitoring assembly further comprising a movable and flexible means located within said filler assembly for connecting with said vertical member, and said movable and flexible means further including a means for floating upon the surface of said fluid; (e) whereby the variations in the fluid level of said reservoir cause said vertical member to correspondingly travel with respect to said rotatable member in a manner to allow a visual interpretation to be made with respect to a full/depletion level of said reservoir, and said rotatable member being variable through a circular arc to provide improved visability to an operator conducting maintenance.
Claim 15
Dependent Claim
