Copying

Note

In groups B 23 Q 33/00 or B 23 Q 35/00, the following term is used with the meaning indicated:

-

"copying" covers the derivation of a required shape from a pattern, of the same or a different shape or scale, by a mechanism or equivalent means controlled by a member following the pattern. The pattern may be a model or drawing, or an element such as a cam incorporated in the operating mechanism of a machine. This term does not cover the derivation of a required shape from simple geometrical shapes, e.g. generating a cycloid by a rolling circle, which in general is provided for in group B 23 Q 27/00.

Methods for copying

Control systems or devices for copying directly from a pattern or a master model; Devices for use in copying manually

Copying discrete points from the pattern, e.g. for determining the position of holes to be drilled

using a feeler or the like travelling along the outline of the pattern, model or drawing; Feelers, patterns, or models therefor

specially adapted for controlling successive operations, e.g. separate cuts, on a workpiece

Means for transforming movement of the feeler or the like into feed movement of tool or work

mechanically only

involving electrical means (programme recording for copying purposes in a separate apparatus G 05, G 11)

using mechanical sensing

the feeler opening or closing electrical contacts

the feeler varying the impedance in a circuit

varying resistance

varying capacitance

varying inductance

using non-mechanical sensing

Sensing by using optical means

Sensing by means of electric discharges

Sensing by using magnetic means

controlling one or more electromotors

controlling fluid motors

involving fluid means (B 23 Q 35/16 takes precedence)

with special means for varying the ratio of reproduction

specially adapted for compensating for wear of the tool

Feelers; Feeler units

designed for physical contact with a pattern or a model

for control of a mechanical copying system

for control of an electrical or electro-hydraulic copying system

in which the feeler makes and breaks an electrical contact or contacts, e.g. with brush-type tracers

in which the feeler varies an electrical characteristic in a circuit, e.g. capacity, frequency

for control of a hydraulic or pneumatic copying system

designed for sensing the pattern, model, or drawing without physical contact (sensing by means of a fluid jet B 23 Q 35/36 )

involving optical or photoelectrical systems

Patterns; Master models

provided with means for adjusting the contact face, e.g. comprising flexible bands held by set-screws

Supporting devices therefor

using a feeler or the like travelling to-and-fro between opposite parts of the outline of the pattern, model, or drawing

Metal-working machines comprising units or sub-assemblies; Associations of metal-working machines or units

Metal-working machines, or constructional combinations thereof, built-up from units designed so that at least some of the units can form parts of different machines or combinations; Units therefor in so far as the feature of interchangeability is important (features relating to particular metal-working operations, see the relevant subclasses, e.g. B 23 P 23/00)

Metal-working machines incorporating a plurality of sub-assemblies, each capable of performing a metal-working operation (B 23 Q 33/00, B 23 P 23/00 take precedence; if the operations are similar and the kind of operation is essential, see the relevant subclass for the operation)

the sub-assemblies being capable of being brought to act at a single operating station

the sub-assemblies being arranged to operate simultaneously at different stations, e.g. with an annular work-table moved in steps (associations of machines connected only by work-transferring means B 23 Q 41/00)

Combinations or associations of metal-working machines not directed to a particular result according to classes B 21, B 23, or B 24 (B 23 Q 37/00, B 23 Q 39/00 take precedence; features relating to operations performed, if the different metal-working operations are of the same kind, see the subclass for the kind of operation, e.g. punching B 21 D, welding B 23 K, grinding B 24 B; features relating to technically specified combinations of different metal-working operations B 23 P 23/00)

Features relating to transfer of work between machines (arrangements for handling work for machine tools co-ordinated in production lines B 23 Q 7/14)

Features relating to relative arrangements of machines

Features relating to organisation of working of machines

Features relating to maintenance of efficient operation
