PROVISIONAL SPECIFICATION.
Machinery for Notching, Planishing, and Grinding Spades, Hoes,
and Edgetools.
1, THOMAS ALFRED YORK, 50 Wednesfield Road Wolverhampton Edgetool
Maker's Engineer do hereby declare the nature of this invention to be as
follows:-
By employing suitable mechanical motion, steam or hydraulic power, I would
place a bolt in front of a pair of rolls, or a bolt under one roll on which I would
fix dies suitable for notching and planishing and would force the dies through, or
under the rolls, I would place a small roll at the back of main roll, to keep work
flat on die.
For grinding I would use same process but would place grindstones, emery
wheels, and cutters, to work over dies.
Dated this First day of January 1895.

Machinery for Notching, Planishing, and Grinding Spades, Hoes,
and Edgetools.
I THOMAS ALFRED YORK 50 Wednesfield Road Wolverhampton Edgetool
Maker's Engineer 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, reference being had to the accompanying
drawings and the letters of reference marked thereon :-
With spades hoes and other tools that are plated out of a mould there must be
some degree of uneveness caused by the roundness of the tools that plate them.
This uneveness must be removed before the work can be satisfactory ground and
polished. To do this I put a bolt, A, on which is fixed the notching and planishing
die, B, to work through the rolls. This die may be of any section or form required.
The bottom roll, C, is a friction roll. The small roll, D, at back of E is to keep
work flat on die. The bearings would keep top roll from the die if there was no
work on die the die would pass through without touching the roll.
In planishing work that has neither eye or rib to hold on the die to keep it
from slipping of the die instead of passing through the rolls, I would fix a rack F
on bolt, A Fig. 2 by side of die B to work into teeth cast round roll E. The rack
would force round the roll and the roll would go the same speed as the die and
the work would be bound to pass through. I have shewn a crank motion to force
die through rolls but I might put a steam cylinder or an hydraulic ram to give
motion to the bolt in place of crank.
For grinding I would put a grindstone any sise up to seven feet in diameter in
place of roll E and a emery wheel or cutter in place of roll D then the application
of the invention for grinding will become self-evident.

page_text: The same machine may be also applied for many other purposes thus it may
be used for forging or stamping by putting the cavities or sections in or on
the die.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
First. Notching planishing and forging different sections the sections being on
dies passing through rolls.
Second. Making the same machine a grinding machine by putting grindstones
emery wheels and cutters in place of rolls substantially as described.
Dated this 12th day of September 1895.
