Class 483
TOOL CHANGING
Class Definition:
This is the generic class relating to a process or apparatus
comprising use of either (A) means for supporting an
implement in position for operative engagement with a
workpiece combined with means to transfer the implement to or
from that support, or (B) means for storing an implement in a
position of repose remote from the operative position,
combined with means to transfer the implement to or from the
storage means.
(1) Note. "Transfer" is used to designate a bodily conveying
of the implement from one position to another. The transfer
means need not be distinct from both the means for supporting
the implement in operative engagement and the storage means,
i.e., the support or storage means may comprise the transfer
means.
(2) Note. "Workpiece" includes material to be modified by
the implement into a product of manufacture and may comprise
a portion of stock material to be separated therefrom
subsequent to modification, or material to be tested by use
of an implement comprising a probe.
(3) Note. "Operative engagement" refers to the relative
implement-workpiece movement during mutual contact which the
implement performs its intended function on the workpiece.
(4) Note. "Implement" consists of a workpiece modifying
device, (e.g., a cutting, abrading, or deforming tool
intended to remove material from the workpiece or plastically
strain the workpiece during contact therewith). Note that an
assembling tool (e.g., a wrench or a screwdriver) is not
considered to be an implement to be transferred under this
class.
Exceptions
Because it is handled in the manner of the "implement" of
this class, each of the following is treated as an implement
in this class: (a) a probe intended to detect or measure a
parameter of the workpiece during contact therewith, (b) a
tool holder that supports a work engaging tool (e.g., chuck,
collet or adapter), (c) a work holder that supports a
workpiece for rotation during treatment, (e.g., a chuck,
collet or adapter). (d) a nonfiller type electrode used for
machining, e.g., for spot welding, electric discharge
machining (i.e., by EDM), electro-chemical machining (i.e.,
by ECM), etc.
(5) Note. The means for supporting the implement must be
distinct from the means for storing, e.g., the mere
recitation of a machine tool with a turret or other means to
shift or index the implement is considered insufficient
subject matter for original classification in this class.
(6) Note. Transferring an implement of this class combined
with transferring another member (e.g., an assembling tool)
using the same transfer means is included in this class.
(7) Note. This class was derived in 1991 from the art then
stored in subclass 568 tool changer of Class 29, Metal
Working. It was assumed that all references appropriate for
original classification in this class (Class 483) were either
as original or as cross-reference in that subclass. Inquiries
were made of various Post Classifiers and Examiners, but NO
ART WAS SCREENED THAT WAS NOT INCLUDED IN 29/568.
