PROVISIONAL SPECIFICATION.
An Improved Device for Holding Lathe Cutters and other similar
Tools Firmly in Position.
I, WILLIAM FREDERICK BEARDSHAW, of Baltic Steel Works, Sheffield, in the
County of York, Steel Manufacturer, do hereby declare the nature of this invention
to be as follows:-
According to this invention a lathe cutter or other similar tool is made flat at
the top, so that the lathe rest, or tool box, or other equivalent device, firmly grips
the same; while the sides of such tool are bevelled off, to allow of its readily
fitting into a V shaped groove formed in the tool holder, thus dispensing with the
cover or covering plate ordinarily used. Such tool holder may be of a square or
any other suitable section.

COMPLETE SPECIFICATION.
An Improved Device for Holding Lathe Cutters and other similar
Tools Firmly in Position.
I, WILLIAM FREDERICK BEARDSHAW, of Baltic Steel Works, Sheffield in the
County of York, Steel Manufacturer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
This invention has for its object to produce a simple and effective tool holder
whereby a lathe cutter or other similar tool is held firmly in position at the same
time that the ordinary covering plate is dispensed with.
To carry out my invention I make the tool holder of a bar of steel, iron or any
other suitable metal or material and of a square or any other suitable section and
form a V shaped groove therein, into which groove the lathe cutter or other tool
fits. The sides of the tool are bevelled off so as to allow of its readily fitting into
such groove, while the top of the tool is made flat, so that the lathe rest, or tool
box, or other equivalent device firmly grips the same. By this means the cover or
covering plate hitherto employed is dispensed with at the same time that the tool
is firmly held in position.
