ENGINEERING IN GENERAL
 F16
ENGINEERING ELEMENTS AND. UNITS; GENERAL MEASURES FOR PRODUCING AND MAINTAINING EFFECTIVE FUNCTIONING OF MACHINES OR INSTALLATIONS
 F16B
DEVICES FOR FASTENING AND SECURING MACHINE PARTS TOGETHER, e.g. NAILS, BOLTS, CIRCLIPS, CLAMPS, CLIPS, WEDGES; JOINTS OR JOINTING (buckles, slide fasteners A44B; ornamental heads for nails, screws, etc. A47G 3/00; joints for building structures in general E04B 1/38; scaffolding couplings E04G 7/00; pipe joints F16L; magnetic holding devices H01F 7/00; electrostatic holding devices H02N 13/00)

 F16C
SHAFTS; FLEXIBLE SHAFTS; ELEMENTS OF CRANKSHAFT MECHANISMS; ROTARY BODIES OTHER THAN GEARING ELEMENTS; BEARINGS
 F16C

Note(s)

The phrase "Rotary bodies other than gearing elements" in the sub-class title, and the relevant groups F16C 13/00 and F16C 15/00, cover any element which rotates so far as its features are affected only by the fact that it rotates.


 F16D
COUPLINGS; CLUTCHES; BRAKES

 F16F
SPRINGS; SHOCK-ABSORBERS; MEANS FOR DAMPING VIBRATION

 F16G
BELTS, CABLES, OR ROPES, PREDOMINANTLY USED FOR DRIVING PURPOSES; CHAINS; FITTINGS PREDOMINANTLY USED THEREFOR (conveyer belts B65G 15/30; traction chains for conveyer chains B65G 17/38, B65G 19/20; gearings using flexible members F16H; preventing or carrying-off electrostatic charges H05F)

 F16H
GEARING
 F16H

Note(s)

In this sub-class

  • "Toothed gearing" includes worm gearing and other gearing involving at least one wheel or sector provided with teeth or the equivalent, except gearing with chains or toothed belts, which is treated as friction gearing.
  • "Conveying . . . motion" includes transmitting energy, and means that the applied and resultant motions are of the same kind, though they may differ in, e.g. speed, direction, extent.
  • "Rotary" implies that the motion may continue indefinitely.
  • "Oscillating" means moving about an axis to an extent which is limited by the construction of the gearing and which may exceed one revolution, the movement being alternately forwards and backwards during continued operation of the gearing.
  • "Reciprocating" means moving substantially in a straight line, the movement being alternately forwards and backwards during continued operation of the gearing.
  • "Reversing" or "reversal" means that an applied movement in one direction may produce a resultant movement in either of two opposed directions at will.
  • "Central gears" includes any gears whose axis is the main axis of the gearing. Sets of rigidly-connected members are regarded as single members.


 F16J
PISTONS; CYLINDERS; PACKING

 F16K
VALVES; TAPS; COCKS; ACTUATING-FLOATS

 F16L
PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES OR CABLES; MEANS FOR THERMAL INSULATION IN GENERAL (pipe systems F17D)
 F16L

Note(s)

In this sub-class, the word "pipes" is understood to include all pipes and tubes not specially adapted to purposes other than that of conveying fluids, materials, or objects. A pipe may or may not be flexible; if flexibility is essential the word "hose" is used.


 F16M
FRAMES, CASINGS, OR BEDS OF ENGINES OR OTHER MACHINES, NOT SPECIFIC TO AN ENGINE OR MACHINE PROVIDED FOR ELSEWHERE; STANDS OR SUPPORTS

 F16N
LUBRICATING (special modifications of devices or systems for use in particular machines or apparatus, see the relevant classes for the machines or apparatus)

 F16P
SAFETY DEVICES IN GENERAL (safety devices adapted to machines or apparatus for special purposes, see the relevant classes for the machines or apparatus)

 F16S
CONSTRUCTIONAL ELEMENTS IN GENERAL; STRUCTURES BUILT-UP FROM SUCH ELEMENTS, IN GENERAL
 F16S

Note(s)

Attention is drawn to sub-class E04C, in which similar elements and structures, restricted to use in the building art, are to be found.
