Pennington, F A; Porr, J W

A pre-set and automatically operable means measures the plasticity of heated coal specimens or other material to be tested, and certain results thereof are indicated on visual readout devices while other results are recorded in print-indicating instrumentalities, including signalling devices, are provided to keep the operator of the apparatus informed as to progress being made. A prime feature is the inclusion of several separate and closely adjacent specimen containers with the test specimen therein in heated condition, one of which may be in testing position while the other is in standby position with heated specimen intact and awaiting its turn to be moved into operating position. Means are provided for so supporting those portions of the testing apparatus which extend into or are connected with the specimen container with the specimen being tested, that they may be easily and quickly elevated at the conclusion of the test and just as easily and rapidly restored to such positions with respect to the appropriately heated specimen and its container which are in a standby position.
