Abstract
A thermometer and a generally elongate mount therefor in which the mount is of channel-shaped cross-section defined by sidewalls which converge along an apex. The thermometer is retained within the channel along the apex by bands which pass through the mount and are looped about the thermometer so that the sidewalls flank and embrace the thermometer. The inner surface of each of the sidewalls is calibrated with centigrade and fahrenheit temperature scales. Various openings are formed in the mount to enable it to be hung, as from a string, and also to enable it to be employed as a sling psychrometer.
Claims12
A temperature responsive measuring device preferably for use by students and having an elongated thermometer tube that is readily replaceable, said device comprising:
- an elongated backing having a front surface of concave configuration along its length, said front surface being defined by a pair of sidewalls diverging from an apex;
- a temperature scale disposed on said forward surface of at least one of said sidewalls;
- and means for mounting the thermometer tube within and along the concave apex of said backing, said sidewalls extending forwardly of and substantially beyond said thermometer tube to protect said tube;
- said means for mounting said thermometer tube comprising;
- a first hole formed in the upper portion of said backing,
- a second hole formed in the lower portion of said backing,
- first and second posts extending rearwardly from and spaced along the rear surface of said backing and each disposed adjacent but spaced from respective first and second holes,
- and at least one continuous and endless elastic band having a first segment extending through the first hole and being looped about the upper end of said thermometer tube, and a second segment that is stretched downwardly to extend and wrap about said rearwardly extending second post,
- whereby said thermometer tube may be readily replaced by removing the second segment from the post so as to loosen the first segment and permit easy withdrawal of the tube from the backing.
For a temperature measuring device preferably for use by students and having an elongated thermometer tube that may on occasion have to be replaced and an elongated backing having a temperature scale disposed on the forward surface thereof, the improvement comprising means for mounting the thermometer along the backing and against the forward surface in a manner to permit easy replacement of the thermometer tube, said means for mounting comprising, means defining a top hole in an upper portion of said backing, said backing having a rear surface, a post spaced from the top hole and extending rearwardly from the rear surface of the backing, and a continuous and endless elastic band means that may be stretched and has opposite securing ends, one end extending through the top hole to form a loop which extends about the upper end of said thermometer tube, the other end being stretched downwardly away from the one end to form a loop that wraps about the rearwardly extending post, whereby said thermometer tube may be readily replaced by removing the looped other end of the elastic band means from the post so as to loosen the said one end of the elastic band means and permit easy withdrawal of the tube from the backing.
