PROVISIONAL SPECIFICATION.
Improvements in Machine Tools for Dressing Stone.
I, WALTER STEPHENSON, of 25 Barlow Moor Road, Didsbury, Manager, do
hereby declare the nature of this invention to be as follows:-
The improvements relate to machine tools for dressing stone, such as the tools in
planing machines and the like, for stonework, and have for object to provide tools
which will require less attention, and be more capable of preserving a true and
efficient working edge than machine stone tools at present in use, and which shall
possess cutting portions or working edges capable of ready adjustment as they
become worn in operation.
To accomplish this, and to effect my improvements, I provide a tool which may
be connected to the planing or other machine in the usual or any suitable manner,
which tool, at or about one extremity, is formed with a recess to receive the cutter,
the latter being, by preference, a suitable plate of steel, which may be provided
with any form of cutting edge, whether straight or saw like, according to the class
of work to be accomplished. When the cutter is placed in the recess, it is held in
position by a cap or cover, which is firmly screwed or otherwise secured to the tool
in such manner as to nip the steel plate, but also to permit of the same being
partially or entirely withdrawn from the tool on loosening the screws or other
fastenings.
As the blade wears in work, and requires to be drawn forward, the space thereby
left in the recess behind may be filled up with pieces of steel, or other packing, to
offer the requisite resistance in work.
By the means described, a tool is provided with an adjustable cutter of plate
steel which, for the most part, obviates the process of grinding, as friction on
the stone tends to renew the edge thereon, and also allows greater truth or
horizontality of the cutting edge to be obtained, than with the forged tools at
present in use.
Variations in the shape of the tool, and cutting plate, and in the method of
securing the plate in position, as well as in other details, may be made without
departing from the peculiar character of the invention.
