Abstract: A scale equipped with a memory display section comprises, separately from a regular display section 19 for indicating a current measured value, additionally a memory display section 20 for indicating the current measured value as a previously measured value in a series of consecutive measurements, wherein a transfer unit 22 executes such a transfer operation that the current measured value indicated in the regular display section 19 can be indicated in the memory display section 20 as the previously measured value in a series of consecutive measurements. A person in charge of measurement no more needs to take the trouble of remembering in the brain or taking notes of the previously measured values in a series of consecutive measurements, such as an incremental measurement, but the current measuring work can be carried out simply by a visual recognition.

Abstract: A mechanical load indicator device continuously monitors the position of the frame of a vehicle relative to some point on the vehicle suspension. The load indicator device is calibrated to be triggered when a certain vehicle load limit is reached. When that load limit is reached or exceeded, the device is "triggered," providing an unambiguous visual indication to the vehicle operator that a vehicle overload condition has occurred. A method of installing, operating, and calibrating an overload detection system is also disclosed.

Abstract: An electronic scale is provided having a frame to which a load cell is secured. The scale further includes a weight receiving means, a first transmission linkage affixed to the cell and a second weight transmission linkage affixed to the weight receiving means. A preloaded coil spring extends between the linkages. The coil spring is preloaded by a force slightly less than the maximum force to which the load cell can safely be subjected so that when subjected to a force, no change in the overall length of the spring occurs until the preloaded force is exceeded. A stop member is affixed to one of the linkages to engage portions of the frame which extend in the path of movement of that linkage when the spring extends.

Abstract: A weight indicator comprises an open top casing containing a resilient column, a relatively rigid pad extending across the top of the column and a scale mechanism for indicating vertical compression of the column in response to weight applied downwardly on the pad, a frictionally mounted indicator element on the casing being movable along a graduated scale on the casing and there being a projection on the pad for displacing the indicator element along the scale as the column reduces in height in response to said downwardly applied weight.

Abstract: A portable weighing scale of reduced size is adapted to permit the weighing of a person while standing with one foot on the platform of the scale, the weight being manifested by an indicator dial which is latched in weight-indicating position and which maintains the weight indication after the person being weighed has stepped off of the platform. A linkage which permits a degree of lost motion is interposed between the platform and the indicator dial, so that the platform can return to its normal position while the indicator dial remains in weight-indicating position, where it remains until reset to its zero position by operation of a latch release. The scale is stable and does not tend to tip over, even when a person's weight is concentrated at one corner of the platform. A one-piece base incorporates, at fixed positions, a plurality of knife edges, formed integrally with the base, which supports the levers and beams making up the linkage between the platform and the indicator dial.
