Abstract
An apparatus to combine temperature indicator sticks used in the welding, metal fabrication, and heat treatment industries and capable of identifying a given temperature of an object is disclosed. The apparatus includes a first temperature indicator stick comprised of a compound which melts at a first temperature, and a second temperature indicator stick formed of another compound which melts at a second temperature. The Apparatus further includes a connector physically connecting the first and second indicator sticks in a single assembly. A method to provide a dual temperature indicator stick is also disclosed.
Claims27
A dual temperature indicator stick comprising:
- a first indicator stick comprised of a compound which melts at a first given temperature;
- a second indicator stick comprised of a second compound which melts at a second given temperature;
- and
- a connector physically connecting the first and second indicator sticks in a single assembly.
A dual temperature indicator stick holder, the holder comprising:
- a housing adapted to receive two temperature indicator sticks within the housing;
- a pair of resistance mechanisms attached to the housing to limit rotational movement of the two temperature indicator sticks about an axis;
- a pair of collets having threads, each collet rotatably coupled to at least one annular lip of the housing;
- and
- wherein each of the pair of collets is configured to engage separate temperature indicator sticks upon rotation of the collet about the housing.
A dual temperature indicator stick apparatus comprising:
- first means for indicating a first temperature;
- second means for indicating a second temperature;
- and
- means for retaining the first means to the second means to form a single indicator stick capable of indicating at least two temperatures.
A method to provide a dual temperature indicator stick comprising:
- forming a first indicator stick of a compound which melts at a first given temperature;
- forming a second indicator stick of a compound which melts at a second given temperature;
- and
- connecting the first and second indicator sticks in a single assembly.
