Surface mounted thermometer

In a thermometer for mounting on a surface and having a housing and a magnet for attaching said housing to said surface the improvement comprising:

• an annular ring disposed and rotatably secured within said housing substantially concentric to said mounting means;
• means for indicating temperature cooperating with said annular ring;
• a temperature responsive member for imparting rotational movement to said annular ring and said means for indicating temperature, said temperature-responsive member being secured within said housing radially outwardly from and substantially surrounding said mounting means;
• and,
• reflective means situated substantially midway between said magnet and the surface on which the housing is mounted when the housing is oriented in its position of use.

A surface mounted thermometer comprising:

• a cup-shaped centrally apertured casing having an arcuately slotted top and an open bottom;
• a cup washer having a centrally apertured bottom and an open top oriented such that the open top of said cup washer and the open bottom of said casing face each other;
• connecting means for joining said cup washer and said casing, said means extending through the central apertures of said cup washer and said casing;
• a magnet for mounting said casing on a surface, said magnet being sandwiched within and between said cup washer and said casing and disposed radially outwardly from said connecting means;
• a substantially annular member concentrically surrounding said connecting means and rotatably secured between said cup washer and the top of said casing;
• a channel for transferring substantially rotational movement to said substantially annular member, said channel being integral with said annular member;
• a bi-metallic element within said casing mounted eccentrically with respect to said connecting means and floatingly engaging said channel such that movement of the bi-metallic element is transmitted to said channel member thereby producing rotation of the substantially annular ring;
• a temperature indicating member being carried on said channel and adapted to traverse the arcuate slot defined by the top wall of the casing.

A surface mounted thermometer comprising:

• a housing defining a chamber having a top wall adapted to provide temperature indicia;
• an annular ring disposed within said chamber;
• support means for rotatably mounting said annular ring inside said chamber, said support means engaging said top wall and extending into said chamber;
• a temperature responsive means for imparting rotation to said annular ring and being mounted eccentrically inside said chamber with respect to said support means;
• means for mounting said housing on a surface, said means being centrally disposed with respect to said annular ring;
• a channel extending radially outwardly from the periphery of said annular ring;
• a channel engaging member driven by said temperature responsive means and being adapted for floating engagement with said channel;
• and,
• a temperature indicating member being responsive to movements of said annular ring and adapted to register temperature against said temperature indicia.

A surface mounted thermometer comprising:

• a housing defining a chamber having a top wall adapted to provide temperature indicia;
• an annular ring disposed within said chamber;
• means for mounting said housing on a surface, said means being centrally disposed with respect to said annular ring, and comprising a hollow shoulder nut and a fastener inserted therethrough for mounting engagement with said surface;
• support means for rotatably mounting said annular ring inside said chamber, said support means engaging said top wall and extending into said chamber;
• a temperature responsive means for imparting rotation to said annular ring and being mounted eccentrically inside said chamber with respect to said support means;
• a temperature indicating member being responsive to movements of said annular ring and adapted to register temperature against said temperature indicia.

A surface mounted thermometer comprising:

• a housing defining a chamber having a top wall adapted to provide temperature indicia;
• an annular ring disposed within said chamber;
• means for mounting said housing on a surface, said means being centrally disposed with respect to said annular ring and comprising a hollow member having a fastener inserted therethrough for mounting engagement with said surface;
• support means for rotatably mounting said annular ring inside said chamber, said support means engaging said top wall and extending into said chamber;
• a temperature responsive means for imparting rotation to said annular ring and being mounted eccentrically inside said chamber with respect to said support means;
• a temperature indicating memeber being responsive to movements of said annular ring and adapted to register temperature against said temperature indicia.

A surface mounted thermometer comprising:

• a housing having a top wall adapted to provide temperature indicia;
• an annular ring disposed under said top wall;
• support means for rotatably mounting said annular ring under said top wall, said support means being secured to said top wall;
• a temperature responsive means for imparting rotation to said annular ring and being mounted under said top wall and eccentrically with respect to said support means;
• means for mounting said housing on a surface, said means being centrally disposed with respect to said annular ring;
• a channel extending radially outwardly from the periphery of said annular ring;
• a channel engaging member driven by said temperature responsive means and being adapted for floating engagement with said channel;
• and,
• a temperature indicating member being responsive to movements of said annular ring and adapted to register temperature against said temperature indicia.

A surface mounted thermometer comprising:

• a housing having a top wall adapted to provide temperature indicia;
• a driven member disposed under said top wall;
• support means for rotatably mounting said driven member under said top wall, said support means being secured to said top wall;
• a temperature responsive means for imparting rotation to said driven member, said means being mounted eccentrically with respect to said support means;
• means for mounting said housing on a surface;
• a channel communicating with and being positioned radially outwardly from the periphery of said driven member;
• a channel engaging member driven by said temperature responsive means and being adapted for floating engagement with said channel;
• and,
• a temperature indicating member being responsive to movements of said driven member and adapted to register temperature against said temperature indicia.
