PROVISIONAL SPECIFICATION.
Improvements in and connected with Moulds for Casting Blue and
like Domestic Blocks employed for Whitening or otherwise
Coating Hearths or other Stones.
I, JOSEPH BEASON, of 22 Mill Street, Ancoats, Manchester, in the County of
Lancaster, Salt Merchant's Agent, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in moulds for casting blue-moulds or
blocks and other domestic moulds, such as are used for whitening or otherwise
coating hearths or other stones in dwellings and which are composed of plain or
coloured plastic substance, which moulds may be used by themselves or in
connection with a press.
Heretofore it has been customary to use moulds made of wood and removing
therefrom the moulds cast by blows directed against the back of the said wood
moulds, which method is not only a source of great trouble and loss of time, but.
also causes the said wood mould to break up in a very short time.
My invention has for its object to obviate these defects by providing a mould
which will last much longer and facilitate the removing of the moulds cast, also the
cleansing of the mould itself.
•
To this end I form such moulds with a detachable bottom and preferably square
in shape. To facilitate the emptying of the said mould I use a die, i.e. a plate
having projecting surfaces corresponding in number, area, and position with the top
or narrower portion of the mould.
When it is desired to remove the moulds cast from the mould, its bottom is
detached and thus the top or narrower part of the moulds cast exposed, so as to
permit of placing thereon the aforesaid die, which is vertically guided and on
pressure being exerted thereon forces out simultaneously all the moulds cast, into a
drawer, or other receptacle, which may be placed below the same.
In order to facilitate the exertion of pressure onto the said die, I suitably secure
the same to a plate arranged to be lowered and raised in a suitable frame, by means of
á screw and handle wheel or other suitable means, the mould itself being placed in
position underneath the said die.

COMPLETE SPECIFICATION.
Improvements in and connected with Moulds for Casting Blue and
like Domestic Blocks employed for Whitening or otherwise
Coating Hearths or other Stones.
I, JOSEPH BEASON, of 22, Mill Street, Ancoats, Manchester, in the County of
Lancaster, Salt Merchant's Agent, 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 improvements in moulds for casting blue-moulds or
blocks, and other domestic moulds, such as are used for whitening or otherwise
coating hearths or other stones in dwellings, which are composed of plain or
coloured plastic substance, which moulds may be used by themselves or in
connection with a press.

page_text: Heretofore it has been customary to use for the said purposes moulds made of
wood and removing therefrom the moulds cast by blows directed against the back
of the said wood moulds, which method is not only a source of great trouble and
loss of time in emptying and cleansing the same, but also causes the said wood
moulds to break up in a very short time.
My invention has for its object to obviate these defects by providing a mould
which will last much longer, facilitate the removing of the moulds cast and also
the cleansing of the mould itself.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is an end view, Fig. 2 a plan, and Fig. 3 a cross section of my improved
mould in position when filled with plastic substance.
Fig. 4 is a cross section of the said mould and die or plate used in connection
therewith showing the emptying of the said moulds.
Fig. 5 is a cross section and Fig. 6 a longitudinal section of an apparatus or
press which may be used for emptying the said mould.
In carrying out my invention and referring to Figs. 1, 2, 3 & 4, I form my
improved mould a, preferably square in shape, with a detachable bottom b, which
is secured to the mould a by means of catches b' engaging studs a¹ on the mould a
or other suitable fastening may be used. The mould a consists as usual of a
suitable number of compartments a² with inclined sides, but instead of having
a permanent bottom the same is made removable so as to give access to the tops of
the moulds e cast. To facilitate the emptying of the mould a I use a die, i.e. a
plate c having projecting surfaces d corresponding in number and position with the
narrow part of the compartments a².
When it is desired to remove the moulds e cast from the mould a its bottom b
is detached by moving back the catches b', as shown in dotted lines Fig. 1, and
placing the mould a in position, as shown in Fig. 4, and thus expose the narrow
part of the moulds e cast, so as to permit of placing thereon the die or plate c, d,
which is vertically guided on studs f and on pressure being exerted thereon, say by
hand, or mechanical means, forces out simultaneously all the moulds e cast, into a
drawer or other receptacle which may be placed below the same.
In order to facilitate the exertion of pressure onto the die or plate c, d, I suitably
secure the same to a plate c', see Figs. 5 & 6, arranged to be lowered and raised in
a suitable frame g by means of a screw furnished with a hand lever i, handle or
wheel, or a cam and lever or other suitable means may be employed for such
purpose, the mould a itself being placed in position underneath the die or plate c, d,
and above a drawer k if desirable.
The die or plate c, d, is rendered interchangeable on the plate c' so as to permit
of using various sizes of moulds a and die or plates c, d.
If desirable the detachable bottom 6 may be dispensed with and the mould a
filled with plastic substance, by placing it on a bench or other suitable surface to
cover the narrow part of the compartments a' and in lieu of removing the moulds e
cast by means of a die or plate c, d, such may be effected by the blow from a
hammer or the like.
It will be understood that the last named method of casting and removing the
moulds e is not effected in as quick and easy manner as when using a die or plate c, d,
or press in addition, but it still offers a great advantage over ordinary moulds as
regards the cleansing of the same.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is―
"In and connected with moulds for casting blue and like domestic blocks employed
for whitening or otherwise coating hearths or other stones
"
