DEFINITION

Classification: 73/862

DYNAMOMETERS:

(under the class definition) Subject matter for measuring or determining force, torque, work or mechanical power.

(1) Note. For purposes of this subclass, a dynamometer may either be employed to measure an applied load or to apply a measured load (e.g., for test purposes).

(2) Note. Dynamometers included in this subclass and

subclasses indented hereunder either have general utility or perform specific measurements or tests which are not elsewhere classifiable. For example, dynamometers that measure certain physical properties or conditions (e.g., weight, gravity, vibration, acceleration and fluid pressure) or test certain devices (e.g., brakes, springs and shock absorbers) are classified elsewhere according to use.

SEE OR SEARCH THIS CLASS, SUBCLASS:

1.08+, for proving or calibrating dynamometers wherein only those details necessary for describing the calibrator is claimed.

54.39, for a viscometer measuring shearing torque between parallel surfaces.

SEE OR SEARCH CLASS 81, Tools,

52.4+, for tools that yield on predetermined overload, and subclass 52.5 for such tools combined with overload signals.

173, Tool Driving or Impacting,

176+, for power-operated tools comprising torque responsive control means and subclasses 20+ for tool driving or impacting combined with force indicating means when more tool structure is recited than is necessary to describe the measuring apparatus.

177, Weighing Scales, appropriate subclasses.

188, Brakes, for friction brakes, per se.

310, Electrical Generator or Motor Structure,

93, for dynamoelectric brakes and subclasses 94 and 95 for automatic control of dynamoelectric brakes.

318, Electricity: Motive Power Systems, appropriate subclasses for a dynamometer controlling a motor.

324, Electricity: Measuring and Testing,

76.77+, for phase measuring and indicating, per se.

338, Electrical Resistors, 2-, 6, for strain gages, per se, and condition responsive means comprising strain gage resistors.

340, Communications: Electrical,

665+, for indicating systems responsive to force or stress.

346, Recorders, appropriate subclasses for recorder structure.

356, Optics: Measuring and Testing, appropriate subclasses.

FORCE:

The strength or energy exerted upon or brought to bear or the cause of motion or change in motion or a state of rest.

POWER:

The rate at which work is done or the rate at which energy is transferred.

TORQUE:

A turning or twisting force or a force that produces or tend to produce rotation or torsion. WORK:

The transference of energy that is produced by motion at the point of application of force which is measured by multiplying the force and the displacement of its point of application in the line of action.
