Belt Shifter. A device for mechanically shifting belts.

Conveyor. A device designed exclusively for transporting bulk materials, packages or objects in a predetermined path and having fixed or selective points of loading or discharge.

Flywheel sometimes referred to as a balance wheel or flywheel pulley means a heavy wheel which by its inertia provides uniform energy of machinery by resisting sudden changes of speed.

Guarded. Shielded, fenced, enclosed or otherwise protected according to these orders, by means of suitable enclosure guards, covers or casing guards, trough or "U" guards, shield guards, standard railings or by the nature of the location where permitted in these orders, so as to remove the hazard of accidental contact.

Guarded by Location. The moving parts are so located by their remoteness from floor, platform, walkway, or other working level, or by their location with reference to frame, foundation or structure as to remove the likelihood of accidental contact.

Machine. The driven unit as distinguished from the driving unit which is defined as a prime mover.

Machine Parts. All moving parts of the machine, except those forming part of the point of operation.

Momentary Contact Device. A device which requires constant pressure by the operator to operate the machine.

Nip-point. That location along the inrunning side(s) of rotating part(s) which permits a part of the body to be caught between two moving part(s) or between a moving part and a stationary object.

Power Drive, Portable. A device used to provide rotary motion which can be used to grip and rotate a pipe or die head to thread, cut and ream.

Prime Mover. An engine or motor whose main function is to drive or operate other mechanical equipment.

Sheaves. Grooved pulleys, unless used as flywheels.

Tail Rod. The extension of piston rod passing through a stuffing box in the outside head of an engine cylinder, compressor cylinder or pump cylinder.
