I DAVID MILLWARD of Bowling Green in the County of Worcester Engineer
do hereby declare the nature of the said Invention for IMPROVEMENTS IN THE
MANUFACTURE OF BRICKS QUARRYS TILES AND OTHER SIMILAR ARTICLES OF
CLAY REQUIRING MOULDS to be as follows:-
I place upon a travelling table a lorry carrying several moulds such as ordinarily
in use for the manufacture of similar articles by hand, and having brought them
under a machine carrying the requisite dies holding the clay I raise the table and
lorry up to the dies for the purpose of filling the moulds having filled the moulds
I separate them from the die by passing a single wire between all the dies and the
moulds, they are then taken upon the lorry to their destination for drying.
Any suitable means of forcing the clay from the die into the moulds may be
employed.

page_text: I, DAVID MILLWARD of Bowling Green in the County of Worcester Engineer
do hereby declare the nature of my said Invention for IMPROVEMENTS IN THE
MANUFACTURE OF BRICKS QUARRIES TILES AND OTHER SIMILAR ARTICLES OF
CLAY REQUIRING MOULDS, 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 Drawings hereunto annexed and to the letters and
Figures marked thereon similar letters referring to similar parts on each of the
Drawings, that is to say :-
This Invention refers to improvements in machinery for the manufacture of the
articles named in the title and by which machinery the clay is severed from the
moulds and dies by means of a wire working horizontally.
Fig. 1 is a front elevation of the machine. Fig. 2 a back elevation and Fig. 3 a
side elevation. (AA) and (A') are the standards carrying all the working parts
of the machine. (B) is a table upon which and by which these working parts are
carried. (C) is a lorry carrying a mould bed (D) and travelling into and out of
the machine upon the tram rails (E). (F) is a stop block keeping the lorry in
position when under the centre of the machine. (G) is a die box attached to the
clay cylinder (H) at the point (I). (K) is a steam cylinder with its piston (L)
and cross head (M) which cross head works vertically in slides in the internal
edges of the standards (AA). The steam piston rod (L) continues through the
cover of the clay cylinder (H) and is furnished with second piston plate (N).
(0) is an aperture through which the plastic clay is fed into the clay cylinder (H)
whence by steam being admitted into the cylinder (K) pressure is brought to bear
upon the piston (L) and communicated to the piston plate (M) forcing the clay in
the cylinder (H) down into the dies in the die box (G). The portion of the table (B)
upon which the lorry (C) stands when in the centre of the machine is maintained in
a plane with the table (B) by the lever (P) and balance weight (Q) until raised out
of that plane by pushing the lever (R) working in a toothed rack, which action
raises the free portion of the table (B) and the lorry with its empty moulds up to
the die box (G). The action of the steam then forces the clay into the moulds and
by drawing back the lever (S) the wire (T) carried by bracket pieces (T¹) is drawn
across between the moulds and the dies and cleanly cuts off the connection, the
lorry is then withdrawn, fresh moulds are substituted and the operation renewed.
(U) is a rod with a treadle it works through a slot in the table (B) and is
connected by a lever arm with that portion of the table which rises with the lorry
it is for the purpose of enabling the operator to keep the lorry up to its work
whilst his hand is operating the cutting wire. The rod (U) is jointed onto a cross
bar (V) passing through stags (W) and supporting vertical rods (Y) having an
eccentric action at their foot and passing up to the underside of the table (B).
The die box (G) is separable from the clay cylinder (H) at the point (I) for the
purpose of enabling the operator to change the dies when requisite."
Having thus described the nature of my said Invention and the manner in
which the same is to be performed I claim Firstly. The travelling table upon
which rides the lorry carrying the moulds, which moulds are to be brought under
the dies to receive the clay from the dies and the mechanism by which such table
is worked. Secondly I claim the eccentric action which enables the operator to
independently lower the table after having severed the clay from the dies. Thirdly

page_text: I claim the mechanical appliances by means of which the horizontal wire or wires
work between the moulds and dies and sever the clay, and Lastly I claim the
several improvements in machinery for the manufacture of bricks quarries tiles and
other similar articles capable of being moulded in olay as herein more fully set
forth and specified.
