PROVISIONAL SPECIFICATION.
Improvements in Stone-breaking Steadys or Apparatus.
I, THOMAS EDWARD CADDY of Wycliffe Street, New Basford, in the Town and
County of the Town of Nottingham Ironfounder and Messrs. CADDY AND Co.
LIMITED Ironfounders Mansfield Road Nottingham do hereby declare the nature of
my invention for IMPROVEMENTS IN STONE BREAKING STEADYS OR APPARATUS
to be as follows:
-
I cast a steady block of the usual or any other convenient shape having one or
more of its sides chilled, or I construct or cast a suitable iron frame of any suitable
shape and size preferably square or round on the top side of which I fit a cast metal
plate or top preferably the same size as the exterior of the frame. On the underside
of the said plate a projection is formed which fits in a cavity of the frame
corresponding in size and shape to the said projection so as to hold it firmly in
position.
To secure it still more rigidly I cast a bolt in the centre of the said plate on the
underside thereof. The said bolt passes through a hole in a strip at the underside
of the before described frame and is made fast thereto with a nut or cotter.
The said plates are moulded and cast face downwards on metal chilling plates
whereby the face is chilled and made hard. I also get an additional chill by having
a large head on the end of the bolt that is cast into the centre of the said plate.
By these means the surface and body of the said top plate rendered hard and dense
and its elasticity is considerably reduced whereby stones and the like can be broken
with less force and lighter hammers and the face of the plate is more durable than
ordinary steadys.
I also provide a cast metal chilled face hammer of suitable shape and size. The
faces of the hammers are cast in chills which are placed in and form part of the
mould therefor.

COMPLETE SPECIFICATION.
Improvements in Stone-breaking Steadys or Apparatus.
We, THOMAS EDWARD CADDY of Wycliffe Street, New Basford, in the Town
and County of the Town of Nottingham Ironfounder and Messrs. CADDY AND CO.
LIMITED of No. 1 Mansfield Road in the Town of Nottingham aforesaid 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 relates to a stone breaking steady-block of the usual or any other
convenient shape and size having one or more of its sides chilled in the process of
casting and, to a steady block with a loose or moveable chilled-face top.
In order that this description may be more clearly understood we annex hereto
drawings
Fig. 1 of which shows a section in elevation of the constructed steady-block
with the chilled face top in position.
Fig. 2 is a plan of the frame thereof only with the top removed.
M

page_text: A. is a frame of cast iron of any suitable size and shape, having at the upper
part thereof a recess or seat B into which fits a moveable cast iron top C. D is a
bolt the head E of which is cast into the top C.
When the top C is in position the lower end of the bolt D enters and passes
through the hole in the bar G, which forms part of the frame already
mentioned. The said bolt is secured to the bar G by a nut H cotter or other
suitable contrivance on the under side so that when it is tightened the top C is
firmly seated on the seat or recess B. The top C above described is moulded and
cast face downwards on metal chilling plates, whereby the face K is chilled and
made hard. I also get an additional chill by having the head E of the bolt D of a
larger size than usual.
By these means the surface and body of the top plate C. is made hard and dense
and its elasticity considerably reduced, whereby stones and the like can be broken
with less force, and lighter hammers, and the face of the plate is more durable than
ordinary steadys. We also provide a cast metal chilled-face hammer of suitable size
and shape. The faces of the hammers are cast in chills which are placed in and
form part of the mould.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1st. A stone breaking steady-block of the usual or any other size or shape
having one or more of its. sides chilled in the process of casting as hereinbefore
described.
2nd. A stone breaking steady block constructed with a loose or removable
chilled-face top substantially as and for the purpose described in the accompanying
drawings.
