DEFINITION

Classification: 173/141

(under the class definition) Apparatus comprising a means to positively cause or progressively control the forward movement of the tool into or along the work, such movement being in addition to a cyclic forward and backward or lateral motion of the tool.

(1) Note. The forward movement and cyclic motion of the tool may be caused by the same power source or by a different power source.

(2) Note. For classification under this definition the means to positively cause or progressively control forward movement of the tool must be adapted to urge or resist forward movement continuously during the forward movement of the tool. Means which are adapted merely to stop the advance at specific points are classified on other features.

SEE OR SEARCH THIS CLASS, SUBCLASS:

4+, for automatic control of tool advance causing or controlling means.

11, for automatic control of drive means in response to sensed condition of advance causing or controlling means. 19, for a means to advance the tool through a self acting advance and retraction cycle.

24, for running gear structure of a vehicle support for the tool drive, in which the movement of the vehicle causes the tool to advance.

38, for a swinging arm advance causing means with the drive means guided to rectilinear advance.

52, for a single advance or manipulating structure for plural tool drives.

53+, for a grip drive to cyclically reciprocate a tool and permit advance.

58+, for work cleansing controlled by relative movement between the advance causing or controlling means and the drive.

59+, for work cleansing by fluid for advance causing or controlling motor.

77, for cleansing fluid controlled by control for advance causing or controlling means.

81+, for a means to control advance and cyclically reciprocate a cable operated tool.

112+, for an impacting device combined with a means to cause

or control advance of a hammer head.

165+, for a relatively fixed means to drive an advancing tool about an axis combined with a means to stop relative tool advance. SEE OR SEARCH CLASS

829+, for constant length alternation stroke with means operable during motion to displace the end limits, and subclasses 840+ for a rotary driven device with means operable during motion to adjust the position of the device relative to its supporting structure.

401+, for means to convey work relative to a cutting station.

47, for a carriage feed for a wood turning tool.
