IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF BRICKS."
Year: 1876

page_text: LETTERS PATENT to William Love and George Love, the younger, both of
Malton House, Lanchester, in the County of Durham, for the Invention of
"IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF BRICKS."
PROVISIONAL SPECIFICATION left by the said William Love and George
Love at the Office of the Commissioners of Patents on the 24th February 1876.
WILLIAM LOVE and CEORGE LOVE, the younger, both of Malton House, Lan-
chester, in the County of Durham. "IMPROVEMENTS IN MACHINERY FOR THE
MANUFACTURE OF BRICKS."
According to our Invention the moulds are applied upon a circular frame which
revolves on a shaft. The bottom of each mould is formed by a closely fitting but
moveable block suspended from the main shaft by a pin and socket. When the parts
are in position for the filling of a mould the block is at its lowest position in the
mould, and as the frame revolves the block is there held by guides for that purpose,
until at the opposite position or other suitable part the block rises in the mould so
as to force the moulded plastic matter therefrom on to a spring platform, the
elasticity of which is regulated to admit of its descent by the weight of the
moulded brick received on to it; the brick is now ready to be carried to the drying
flat.
As the machinery revolves the blocks in the respective moulds progressively
descend therein to receive the plastic substance to be moulded, and then rise to force
out the moulded matter in the form of bricks.
The form and character of the moulds may be varied; by these means simplicity
and economy of manufacture are attained.
Apparatus arranged as described will work without steam or other power, the
weight of the brick in the mould carrying the frame round the desired distance.
The clay or plastic matter being put into the moulds by hand, the bricks obtained
will be equal to those made with the ordinary hand mould.

said William Love and George Love in the Great Seal Patent Office on the
21st August 1876.
WILLIAM LOVE and GEORGE LOVE, the younger, both of Malton House, Lan-
chester, in the County of Durham. "IMPROVEMENTS IN MACHINERY FOR THE
MANUFACTURE OF BRICKS."
According to our Invention the moulds are applied upon a circular frame which
revolves on a shaft. The. bottom of each mould is formed by a close fitting but
moveable block suspended from the main shaft by a pin and socket. When the
parts are in position for the filling of a mould the block is at its lowest position
in the mould, and as the frame revolves the block is there held by guides for that
purpose, until at the opposite position or other suitable part the block rises in the
mould so as to force the moulded plastic matter therefrom on to a spring platform,
the elasticity of which is regulated to admit of its descent by the weight of the
moulded brick received on to it; the brick is now ready to be carried to the drying
Hat.
As the machinery revolves the blocks in the respective moulds progressively
descend therein to receive the plastic substance to be moulded and then rise to
force out the moulded matter in the form of bricks.
The form and character of the moulds may be varied; by these means simplicity
and economy of manufacture are attained.
But that the Invention may be the better understood I will by the aid of the
accompanying Drawings proceed to describe means pursued by me in carrying the
same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews by side view; Figure 2 by end view; and Figure 3 by plan view,
an arrangement of apparatus according to our Invention.
In each of the views the same letters indicate corresponding parts.
a, a, shews the main stationary framing; b is the main shaft or axis on
which revolves the circular frame c. This frame is formed with four chambers
or mould boxes d, d, but this number may be varied. Each of these moulds or
chambers d is provided with a moveable bottom e forming a moveable block,
piston, or plunger. Each of these pistons or plungers is connected to an arm or
a rod e¹ formed with an opening through it to receive a cross bar e³, the ends of
which are received into the slotted openings f formed in the arms c¹ of the frame c,
with capability of movement therein. The frame c with the parts carried thereby,
is capable of revolving in the direction of the arrow (Figure 1), and in so doing the
piston or plunger e will be at the bottom of its mould box when each mould box d
is occupying the highest and central position, and at that time the mould box & will
be in position to receive clay or other plastic material to be moulded. Then as
the frame e revolves the mould box d, which was for the time at the top, progres-
sively comes to be the lowest; but during the second quarter of their partial
rotation the piston or plunger is held back with the plastic matter in the mould
box by the ends of the rod e³ thereof being acted upon by the curved guides or
holders g, but when each mould box with its plunger arrives at the lowest part of
its course, or immediately under the shaft or axis b, the ends of the rod e are
released from these guides g, and the weight of the plunger e causes it to descend
in the mould box and force out the moulded matter, it had contained, and this
matter is then received on to the small table h carried by one end of the balance
lever i, which is supported to tum on the fixed fulcrum . The table h is also
formed with a stem h¹ moving in a socket j, by which it is guided in its vertical
movement. As shewn a balance weight 2 is applied as the elastic means to the
lever i, but in place of weight a spring may be applied adapted to the required

page_text: elasticity. Each brick k as thus received on to this table h is ready to be carried
to the drying flat.
After the delivery of each brick as the frame c revolves the pistons e are each
drawn in succession back towards the centre or axis b by the ends of the rod es
coming against the inner surface of the curved guide until on arrival at the
uppermost position to receive the clay or other plastic substance to be moulded,
when the block or piston e will be again at the lowest position in the mould. Each
block or plunger is formed in two parts, one metal (1) the other wood (2), but this
may be varied.
Apparatus arranged as described may be worked without the use of steam power,
the weight of the plastic matter in the mould to form the brick being sufficient to
cause the partial rotation of the circular frame c; and the clay or plastic matter
being put into the respective moulds by hand, the bricks obtained will be found
equal to those ordinary made in hand moulds.
Having thus described our Invention and means which we adopt in carrying the
same into effect, we would have it understood that what we claim is, the arranging
or combining parts forming apparatus for the manufacture of bricks, as described.
In witness whereof, I, the said George Love, the younger, have hereunto set my
hand and seal, this Eighteenth day of August, in the year of our Lord
One thousand eight hundred and seventy-six.
GEORGE LOVE, JUN. (L.S.)
