PROVISIONAL SPECIFICATION.
improvements in Dies and Supports therefor for Use in connection
with Stamping Mills for Crushing Minerals and Ores.
I NATHAN GOLD KIMBERLEY of Springfield Road New Southgate in the
County of Middlesex Engineer do hereby declare the nature of this invention to
be as follows :—
The dies to which my improvements are applicable are those used in connection
with stamping mills for crushing minerals and ores.
Of the total weight of dies as at present made and applied but little more than
half can be utilised in actual work the remainder being of no further use in the
stamping mills is put away as scrap.
The object of my invention is to reduce the weight of that part of the die that is
put away as scrap when the die is worn out thereby enabling a much larger
proportion of the metal in the die to be used up in actual work.
Instead of forming the die with its base all in one piece I make the upper part
or die proper separate from the base or supporting part. By this means when the
die is worn out there will remain only a small portion of it to be put away
as scrap.
The base will serve to support an indefinite number of dies one at a time each
being replaced with a new die when worn out.
By this means the weight of metal passing to scrap will be greatly reduced
thereby effecting a material saving in the cost for crushing minerals and ores.
Dated this 23rd day of October 1893.

Improvements in Dies and Supports therefor for Use in connection
with Stamping Mills for Crushing Minerals and Ores.
I, NATHAN GOLD KIMBERLEY of Springfield Road New Southgate in the
County of Middlesex 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:-
The dies to which my improvements are applicable are those used in connection
with stamping mills for crushing minerals and ores.
Of the total weight of dies as at present made and applied but little more than
half can be utilised in actual work the remainder being of no further use in the
stamping mills is put away as scrap.
The object of my invention is to reduce the weight of that part of the die that is
put away as scrap when the die is worn out thereby enabling a much larger
proportion of the metal in the die to be used up in actual work.
Instead of forming the die with its base all in one piece I make the upper part
or die proper separate from the base or supporting part. By this means when the
die is worn out there will remain only a small portion of it to be put away
as scrap.
In order to more clearly explain and illustrate the manner in which my invention
is carried into effect I annex hereto a sheet of drawings in which
Fig. 1 represents my improved die formed with a spigot A on the underside.

page_text: :
Fig. 2 represents the base or support for my improved die formed with a hole B
into which the spigot A of the die enters and by which the die is retained in its
proper position.
Fig. 3 represents the die resting on its base or support the spigot A. of die having
entered the hole B in the base or support.
The base will serve to support an indefinite number of dies, one at a time, each
die being replaced as worn out by a new die.
By this means the weight of metal passing to scrap will be greatly reduced
thereby effecting a material saving in the cost of crushing minerals and ores.
Having now described the nature of my invention and shown how the same may
be carried into practise I declare that what I claim is
The construction of dies for stamping mills as herein described having the upper
or wearing part made separately from the lower or supporting part the upper part
or die proper being provided with a spigot or projection to enter a corresponding
hole or recess in the base or support substantially as and for the purpose herein
described.
