Class 173
TOOL DRIVING OR IMPACTING
Class Definition:
SUBJECT MATTER OF THE CLASS
(A) The purpose of this class is to provide a search for
subject matter directed to means for driving a tool and also
reciting some feature relating to the tool, or reciting a
combination of features peculiar to driving a tool which
cause separate classification in the specific motor classes,
and in the specific machine element and mechanism classes to
be impractical, but which subject matter is of such general
application in the tool arts that separate classification in
each specific tool class is also impractical.
(B) The term, tool, as used in this class means primarily a
work contacting element which functions to effect some
physical alteration in the work, such as chipping or boring,
but is also used to include other elements which are driven
in the same manner as such a tool (e.g., a nail or post). It
must be noted, however, as explained in the next paragraph,
that a means which impacts a tool is not in itself, regarded
as a tool.
(C) The term, impacting device, as used in this class defines
a means including a mass of material (i.e., hammer head)
which is specifically intended to deliver an impact or blow
to a tool as defined in paragraph B and is not itself a tool
but is defined as a species of means for driving a tool.
(D) This class, in accordance with the purpose of paragraph
A, provides for an impacting device, as defined in paragraph
C, or a means to actuate the hammer head of an impacting
device, said impacting device or means to actuate said hammer
head being claimed in combination with at least one of the
following features relating to a tool as defined in paragraph
B: (1) a nominally recited tool, (2) a means to retain or
hold a tool to receive a blow, (3) a means to align a tool
with respect to the hammer head to receive a blow, or (4) a
means (anvil) situated between the hammer head and a tool and
which is intended to transmit a blow from the hammer head to
the tool.
(E.)This class also provides for a motor and/or a machine
element or mechanism for driving a tool claimed in
combination with one or more of the following: (1) a means
for causing, controlling, or selectively preventing the
advancing movement of a driven tool, (2) a cleansing means,
i.e., a means for cleaning the area of tool operation or (3)
a manipulating handle. In the absence of a separate drive
means, a means to cause, control or selectively prevent
advance claimed in combination with a cleansing means will be
classified in this class.
(F) This class also provides for processes of operating
apparatus included under the class definition and not
claiming any additional feature limiting the process to a
particular art.
(G) This class also is intended to provide for subject matter
in accordance with the purpose of paragraph A not
specifically provided for in paragraphs D, E and F or
excluded by paragraphs H and J. Examples of such subject
matter are means for driving a tool combined with (1) a
vehicle support for the drive, (2) work engaging means
supporting the drive or (3) means to adjust the position of
the axis of tool advance. This class also includes
subcombinations of impacting device structure which are not
elsewhere classifiable such as a specific means to transmit
an impact from a hammer head to a tool.
(H) This class is not intended to provide original
classification for a claim having any specific recitation of
(1) the work contacting portion of the tool, (2) plural,
cooperating tools (e.g., angularly related tools), (3) and
underlying work support opposed to the tool, or (4) any other
specifically recited feature pointing to classification in a
particular tool art and not provided for in this definition.
An exception to (1) is that the recitation of the work
contacting portion of the tool as being broadly provided with
a cleansing fluid passage or port is not considered to define
the work contacting portion of the tool with sufficient
specificity to preclude classification from Class 173.
(J) Not all classes have been cleared of art such as defined
herein. This class, therefore has only such art as is
cleared from other classes. Section III of the class
definition indicates those classes which have bodies of art
in conflict with the definitions of this class.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
If both the drive means and means to cause, control or
selectively prevent advance comprise merely gear or
mechanical motion elements as defined in Class 74, Machine
Element or Mechanism, classification is in Class 74.
However, if structure is claimed which goes beyond the scope
of Class 74, such as specific motor structure, a vehicle
support for the drive, work engaging support means or means
to adjust the position of the axis of tool advance,
classification is in Class 173.
A motor vehicle having a power take-off of general utility,
but which may be described as for the purpose of driving a
tool is classifiable in Class 180, Motor Vehicles,
particularly subclasses 53.1+. Therefor, to be included under
(1) in G above, the means for driving a tool must include a
structural feature of relationship which is peculiar to tool
driving.
RELATIONSHIP TO SPECIFIC TOOL CLASSES
The claiming of specific work contacting tool structure in
combination with subject matter of this class will cause
original classification of the patent in the appropriate
specific tool class, as will the claiming of plural,
angularly related cooperating work contacting elements such
as angularly related tools or a tool combined with an
opposing support for the work. However, many of the specific
tool classes have not been cleared as to original
classification in accordance with this line, nor has complete
cross-reference of subject matter been made. The classes
which should be closely investigated when making a search for
the subject matter provided for under this definition are as
follows:
15, Brushing, Scrubbing, and General Cleaning
30, Cutlery
56, Harvesters
81, Tools
82, Turning
83, Cutting
125, Stone Working
142, Wood Turning
144, Woodworking
172, Earth Working
234, Selective Cutting (e.g.,Punching)
408, Cutting by Use of Rotating Axially Moving Tool
433, Dentistry
451, Abrading
470, Threaded, Headed Fastener, or Washer Making: Process
and Apparatus

addition, to the housing required to support the drive
structure. Such "machine frame" structure may be
significantly recited by physical limitations of the
structure of by a named recitation of two or more parts of
the structure including the interrelationship of the parts.

GLOSSARY:
ADVANCE
The forward movement of the tool into or along the work.
Such movement is in addition to the drive movement (i.e.,
cyclic forward and backward or lateral motion of the tool).
Included under this definition as apparatus functioning under
the broad meaning of advance are means for causing,
controlling, or selectively preventing the forward movement
of the tool into or along the work.
CLEANSING
The act of removing matter resulting from the operation of
the tool on the work.
CLEANSING FLUID
A fluid which is adapted to perform a cleansing function upon
work. Such a fluid may be solely described as performing
some other function, such as cooling the work, so long as it
is directed in such a manner as to inherently cleanse the
work.
DRIVE
The motion of a tool which performs a function upon work.
Impact is included under the definition of this term. Also,
any means to cause the drive motion of a tool such as a
motor, cooperating gearing or mechanical movement elements,
or an impacting device.
HAMMER HEAD
The striking element of an impacting device.
IMPACTING DEVICE
A means including a mass of material (i.e., hammer head)
which is specifically intended to deliver a blow to a tool.
The mass of material need not necessarily strike the tool
directly, but may deliver the blow through an intervening
element (e.g., anvil).
IMPACTING
A type of drive function which includes striking a mass of
material (e.g., tool) with another mass of material (e.g.,
hammer head).
MANIPULATING
Moving the tool drive from one place to another to perform a
function upon work. This movement is separate from or in
addition to the advance movement of the tool.
MANIPULATING HANDLE
A means specifically intended to be grasped by the hand or
hands of an operator to move the tool drive, of which it
forms a part, to different positions with respect to the
work, and to be continually grasped by the operator as the
tool advances in performing a function upon work.
MOTIVE FLUID
A fluid used to drive a motor, and including fluid taken from
a stream supplying a motor, or from a stream exhausting from
a motor. Fluid fuel for or fluid exhaust from a combustion
motor is included under this definition.
TOOL
A work contacting element which functions to effect some
physical alteration in the work, such as chipping or boring,
but also includes other elements which are driven in the same
manner as a tool such as a nail or post.
WORK
The object or mass of material which is contacted by the tool
to be physically altered thereby.

Subclass:
1
This subclass is indented under the class definition. Methods
for operating tool driving or impacting devices to perform a
function which is not limited by a manipulative step to a
specific tool art.
(1) Note. This subclass is not intended to form a complete
search for all described processes of operating tool driving
or impacting devices as provided for under the class
definition. Therefore, the search for process claims falling
herein should be completed in the appropriate apparatus
subclass.
Subclass:

may or may not occur, (2) a separate control means and (3) a
separate power operated means to initiate, modify, or
terminate the functioning of the apparatus, said three means
being so related that the sensing means controls operation of
the control means and the control means controls operation of
the power means, all without the intervention of a human
operator.
(1) Note. Apparatus wherein the driven tool constitutes the
sensing means and controls the control means for the power
operated means is included under this definition only if the
control means moves relative to the driven tool. An
apparatus having structure integral with or fixed to the tool
as the sole means to control the operating means is not

features.
(2) Note. A valve having one specific area which senses the
condition of a fluid, and a completely different area which
controls the flow of the same or a different fluid to operate
as power means is included under this definition as separate
sensing and control means. A valve which senses and controls
with the same surface (i.e., a check valve), is not included
and is classified on other features.
