page_text: I, HAROLD STANLEY ILSLEY, of 15, Dorville Road, Lee, in the County of Kent,
Instructor in Manual Training, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to provide a simple and effective means for
holding tools for the purpose of grinding and to carry my invention into effect
I construct my improved tool grinding apparatus as follows:-
It consists of four principal parts. A base bracket piece which is attached to
the grindstone casing this is a flat piece of metal having slotted holes to allow
of adjustment for height this has at its upper end an angle piece upon which is
pivotted the hinge block so that it may move radially in horizontal plane this
block is provided with lugs on either side and to these lugs bars are pivotted one
on either side and these bars are of sufficient length to reach right across the stone
and terminate in handles. From about the centre towards the handle each of
these bars is provided with a series of holes the said holes being drilled so that
those in each bar are opposite to each other. These holes are for the purpose of
attaching the tool holder which fits across the bars and may be fixed in any
position the holes in the bars allow. The tool holder may be simply a piece of
metal fitting across the bars with angle pieces at either side to boft to the holes
in the bars having another piece of metal on top of it and wing nutted bolts
passing through both so that the tools may be clamped between them or the tool
holder may be of a more elaborate form made to revolve and clamp at any angle
and hold any form of tool.
In use the simple form of tool holder is preferably used for wood working tools
such as plane irons chisels and the like, in this case they are simply clamped
between the plates above mentioned and the operator holds the handles of the
bars thus bringing the tool upon the stone at any suitable pressure and while the
grinding is taking place the bars are moved radially from the hinge block across
the face of the stone thus ensuring equal wear of the stone and perfect grinding
of the tool.

I, HAROLD STANLEY ILSLEY, of 15, Dorville Road, Lee, in the County of Kent,
Instructor in Manual Training, 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:―
The object of my invention is to provide a simple and effective means for
holding tools for the purpose of grinding and to carry my invention into effect
I construct my improved tool grinding apparatus as follows. Reference being
made to the accompanying drawings in which Fig. 1 shows the complete apparatus
in perspective and Fig. 2 the said apparatus attached to a stone with a tool
clamped in the tool holder ready for grinding.
A, is the base bracket piece which is attached to the grindstone casing, this
is a flat piece of metal having slotted holes to allow of adjustment for height
and has at its upper end an angle piece upon which pivoted the hinge block B
so that it may move radially in horizontal plane, this block is provided with lugs on
either side and to these lugs bars Care pivoted one on either side and these bars are of
sufficient length to reach right across the stone and terminate in handles. From
about the centre towards the handle each of these bars is provided with a series of
holes the said holes being drilled so that those in each bar are opposite to each
other. These holes are for the purpose of attaching the tool holder D which
fits across the bars and may be fixed in any position the holes in the bars allow.
The tool holder may be simply a piece of metal fitting across the bars with
angle pieces at either side to bolt to the holes in the bars, having another piece
of metal on top of it and wing nutted bolts passing through both so that the
tools may be clamped between them.
In use a simple form of tool holder is preferably used for wood working tools
such as plane irons chisels and the like, in this case they are simply clamped
between the plates above mentioned and the operator holds the handles of the
bars thus bringing the tool upon the stone at any suitable pressure and while the
grinding is taking place the bars are moved radially from the hinge block across
the face of the stone thus ensuring equal wear of the stone and perfect grinding
of the tool.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In tool grinding apparatus the combination of a bracket carrying a pivotted
hinge block with bars hinged thereto the said bars carrying a tool holder and
terminating in handles.
2. The improved tool grinding appliance substantially as herein described and
illustrated in the accompanying drawings.
