Abstract
Abstract Apparatus for measuring and indicating the temperature of the water in a swimming pool is disclosed. A rigid plate having a generally flat upper surface is adapted to be mounted flush with the decking of the swimming pool. The plate has a recess in the center thereof which holds a thermometer. The thermometer has a casing conformed to the shape of the recess in the plate, and a transparent protective face which is flush with the upper surface of the plate. A bulb shaft extends from the bottom of the thermometer casing through an aperture in the bottom of the plate. The bulb shaft is in thermal contact with the water in the swimming pool, either in the skimmer box or via a hollow tube extending from the plate to the pool interior sidewall. The temperature of the water in the pool is indicated on the thermometer below the protective face and is easily visible to anyone standing on the decking of the pool.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
168 words
Apparatus for measuring and indicating the temperature of the water in a swimming pool having a skimmer, said apparatus comprising: a rigid plate adapted to overlie the skimmer and having a generally flat upper surface adapted to be mounted flush with the decking of a swimming pool, said plate having a recess in the center thereof and an aperture in the bottom of said recess and extending through said plate; and a thermometer having a casing conformed to the recess of the plate and adapted to be mounted therein, said thermometer further having a transparent protective face substantially flush with the upper surface of the plate when said thermometer is mounted in said recess, a dial face located below the protective face, and temperature indicating recess having a temperature sensing portion including a bulb shaft extending from the bottom of the casing and projecting through the aperture in the plate and into the water in said skimmer and an indicator between the dial face and the protective face.
Claim 2
Dependent Claim
168 words
Apparatus for measuring and indicating the temperature of the water in a swimming pool having a skimmer, said apparatus comprising: a rigid plate adapted to overlie the skimmer and having a generally flat upper surface adapted to be mounted flush with the decking of a swimming pool, said plate having a recess in the center thereof and an aperture in the bottom of said recess and extending through said plate; and a thermometer having a casing conformed to the recess of the plate and adapted to be mounted therein, said thermometer further having a transparent protective face substantially flush with the upper surface of the plate when said thermometer is mounted in said recess, a dial face located below the protective face, and temperature indicating recess having a temperature sensing portion including a bulb shaft extending from the bottom of the casing and projecting through the aperture in the plate and into the water in said skimmer and an indicator between the dial face and the protective face.
Claim 3
Dependent Claim
161 words
In swimming pool having a surrounding deck, a skimmer located below said deck, and a skimmer lid having an upper surface adapted to be mounted flush with said deck over said skimmer and removable to provide access to said skimmer, means for measuring and indicating the temperature of the water in said swimming pool comprising: a recess in the upper surface of the skimmer lid, and an aperture from said recess extending downwardly through said skimmer lid; and a thermometer having a casing conformed to the recess in the skimmer lid and adapted to be mounted therein, a transparent protective face substantially flush with the upper surface of the skimmer lid, a bulb shaft depending from the casing and projecting through the aperture in the skimmer lid and into the water in the skimmer, and means for indicating and displaying the temperature of water surrounding said bulb shaft immediately below said protective face so that the indicated temperature is readily visible.
Claim 4
Dependent Claim
161 words
In swimming pool having a surrounding deck, a skimmer located below said deck, and a skimmer lid having an upper surface adapted to be mounted flush with said deck over said skimmer and removable to provide access to said skimmer, means for measuring and indicating the temperature of the water in said swimming pool comprising: a recess in the upper surface of the skimmer lid, and an aperture from said recess extending downwardly through said skimmer lid; and a thermometer having a casing conformed to the recess in the skimmer lid and adapted to be mounted therein, a transparent protective face substantially flush with the upper surface of the skimmer lid, a bulb shaft depending from the casing and projecting through the aperture in the skimmer lid and into the water in the skimmer, and means for indicating and displaying the temperature of water surrounding said bulb shaft immediately below said protective face so that the indicated temperature is readily visible.
Claim 5
Dependent Claim
41 words
Apparatus as recited in claim 2 wherein the bulb shaft has a wider threaded portion adjacent the casing, and additionally comprising a nut adapted to engage the threaded portion of the bulb shaft to fasten the thermometer to the skimmer lid.
Claim 6
Independent Claim
181 words
A device fOr measuring and indicating the temperature of the water in a swimming pool comprising: a rigid plate mounted in the decking of said pool, said plate having an upper surface adapted to be substantially flush with said decking, said plate further having a recess in the center thereof, and an aperture extending from said recess through the bottom of said plate; a hollow tube extending from the aperture in the bottom of the plate to the interior surface of the side wall of the swimming pool below the water level in said pool; and a thermometer having a casing conformed to the recess in the plate and adapted to be mounted therein, a transparent protective face substantially flush with the upper surface of the plate, a flexible bulb shaft depending from the casing and projecting through the aperture and through the tube to a point adjacent the interior surface of the side wall of said pool, and means for indicating the temperature of said bulb shaft immediately below the protective face so that the indicated temperature is readily visible.
Claim 7
Independent Claim
181 words
A device fOr measuring and indicating the temperature of the water in a swimming pool comprising: a rigid plate mounted in the decking of said pool, said plate having an upper surface adapted to be substantially flush with said decking, said plate further having a recess in the center thereof, and an aperture extending from said recess through the bottom of said plate; a hollow tube extending from the aperture in the bottom of the plate to the interior surface of the side wall of the swimming pool below the water level in said pool; and a thermometer having a casing conformed to the recess in the plate and adapted to be mounted therein, a transparent protective face substantially flush with the upper surface of the plate, a flexible bulb shaft depending from the casing and projecting through the aperture and through the tube to a point adjacent the interior surface of the side wall of said pool, and means for indicating the temperature of said bulb shaft immediately below the protective face so that the indicated temperature is readily visible.
