Abstract: A temperature recorder which produces a continuous graphic record, scribed on tape, of the temperature existing in an enclosure (such as a refrigerated railroad car) curing a given period of time (e.g., the transit time of such a railroad car). The recorder comprises a guided, downwardly movable casesuspended by an upper-end anchored tape-which slowly gravitationally descends upon unwinding, under influence of the weight of said case and at a controlled rate, of the tape from a spool on such case, and the latter being fitted with a temperature-responsive device including a variably movable stylus which progressively scribes on the tape as the case so descends; the tape having a graph thereon which reflects the scribing in terms of temperature in relation to time.
