I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a new moulding box for forming plates used for build-
ing purposes with shaped edges from pulpy substances capable of hardening. Such
plate may be formed with a groove in its edges. In addition to this the edges
of the bearing joints are formed with dovetails, whilst the vertical edges have
formed in them a number of conical recesses. In the construction of a wall or
partition the first layer or row of the plates is placed in position, whereupon the
recesses in the vertical edges are filled with a rapidly hardening cement.
cement flowing into these recesses a¹ forms, so to speak, joining pegs for the plates.
The second layer or row of plates is then placed in position upon the first row
and cement poured into the channels of the joints. In this manner a wall is
formed, in which the plates of which it is constructed are very firmly joined
together.
The
The new moulding box used for the manufacture of these plates has a bottom
plate to which are hinged side flaps or pieces. To one of these side pieces the
cover is likewise hinged. This side piece, the side piece opposite to it, and the
top and bottom are provided-if building plates of the kind above described are
to made upon their inner faces, with narrow beads or ribs running in the same
direction; of which the ribs of the top and of the bottom are furnished with pegs
whilst the middle portions of the ribs upon the two side pieces project, and on each
side of the projecting portion a retreating ledge is situated.
After the side pieces have been brought into position opposite one another upon
either side of the bottom plate and connected one with another, by means of bolts
or latches and staples for example, divisions or partitions are inserted by way of
the upper portion of the box still remaining open, such partitions fitting into the
openings between the ribs. The said partitions form narrow compartments which
are filled with the substance from which the plates are to be formed. After this
the lid is closed down and the substance left sufficiently long to harden. When
this has taken place, the lid and the two side pieces which are parallel to the parti-
tions are opened out, and the hardened plates are removed from the box in succes-
sion and alternately with the partitions. These, plates have edges of the desired
section and can be employed for constructional purposes either immediately or after
being submitted to a special drying process,

formed; according to the required section the projecting surfaces upon the walls
of the box are varied in each case.
An Improved Moulding Box for Forming Plates for Building
Purposes.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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:-
1
This invention relates to a new moulding box for forming plates used for build- 1
ing purposes with shaped edges from pulpy substances capable of hardening.
In the accompanying drawing-
Figures 1 and 2 are vertical sections at right angles through the improved
moulding box;
Figure 3 is a horizontal section through the latter on the line 3-3 (Figure 1); 2
Figure 4 is a plan of the unfolded moulding box;
Figure 5 is a perspective view, and
Figure 6 a vertical section of a building plate formed by the improved moulding
box;
Figure 7 shows a part of a wall built up of such building plates.
Similar letters refer to similar parts throughout the several views.
The improved moulding box has a bottom plate 6 to which are hinged side flaps
or pieces c. To one of these side pieces the cover d is likewise hinged. This ride
piece, the side piece opposite it, and the top and bottom are provided, upon their
inner faces, with narrow beads or ribs e running in the same direction; of which
the ribs of the top d and of the bottom 6 are furnished with pegs e¹ whilst the
middle portions of the ribs e upon the two side pieces c project, and on each side
of the projecting portions a retreating ledge e³ is situated.
2
After the side pieces c have been brought into position opposite one another upon
either side of the bottom plate band connected one with another, by means of
3
indented falling latches e engaging projections for example, divisions or parti-
tions f are inserted by way of the upper portion of the box still remaining open,
such partitions f fitting into the grooves e formed by the ledge e³. The said parti-
tions f form narrow compartments which are filled with the substance, such as
gypsum, from which the plates are to be formed. After this the lid or cover d 4
is closed down and the substance left sufficiently long to harden. When this has
taken place, the lid d and the two side pieces c which are parallel to the parti-
tions are opened out, and the hardened plates A are removed from the box in
succession and alternately with the partitions f. The plates thus formed may be
employed for constructional purposes either immediately or after being submitted
to a special drying process.
The plates A shown in the drawing are formed with a groove a all round their
edges. In addition to this the edges of the bearing joints are formed with dove-
tails a, whilst the vertical edges have formed in them a number of conical
recesses a¹. In the construction of a wall or partition the first layer or row of the
4

page_text: plates A (Figure 7) is placed in position, whereupon the channels or grooves a
in the vertical edges are filled with a rapidly hardening cement. The cement
flowing into the recesses a¹ forms, so to speak, joining pegs for the plates.
The second layer or row of plates A is then placed in position upon the first row
and cement poured into the channels of the joints. In this manner a wall is
formed, in which, the plates of which it is constructed are very firmly joined
together.
"
It is obvious that edges of different section from that above referred to may be
formed; according to the required section the projecting surfaces upon the walls
of the box are varied in each case.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is:-
An improved moulding box for forming building-plates with shaped edges con-
sisting of folding walls hinged together and provided on their inner surface,
according to the desired shape of the edges of the building plates, with corre-
sponding projections or recesses respectively, in combination with removable parti-
tions adapted to be inserted into the moulding box in order to form narrow
compartments within the moulding box to be filled with the substance from which
the plates are to be formed, substantially as and for the purpose set forth.
