Improvements in Brick Moulds, and the Stocks and Fittings used
with same.
We ROBERT WILLIAM JESSON, of 17 Cranbury Avenue, Law Clerk, and
SIDNEY NICHOLS, of 39 Northbrook Road, Builder, and JOSEPH ANDREWS, of
34 James Street, Saint Mary's, Carpenter, all of Southampton, in the County of
Hampshire, do hereby declare the nature of this invention to be as follows:-
Our invention relates to brick moulds, stocks and fittings and comprises various
improvements hereinafter described.
The main object of our said invention is to provide, cheap, and durable brick
moulds, stocks, and fittings, for use in making bricks by hand.
In making a brick mould according to one form or modification of our invention
cach side of same is cast in one piece, the material probably being of malleable cast
iron or steel, the upper and lower edges, and the ends, are provided with a rib, or
bead of a thickness corresponding to about three times that of the sides, and of a
convenient width equal probably to about twice the thickness, and bevelled off and
dying away into the sides, further, a rib midway of the length of mould may be
cast on the sides of same in a vertical or diagonal direction.
The ends of the mould will probably be of iron, or steel plate, the vertical edges
fitting against the sides, being turned or angled into a direction parallel to same,
and to which they are riveted or otherwise fastened, or the ends of moulds may be
otherwise suitably fastened to the sides thus completing the mould.
The stock and frog will probably be in one piece and made of malleable cast iron
or steel.
The essential part of our invention applicable to the stock is that part of same
upon which the mould is placed, (as it would be upon the coach screws or other
similar stock fitting) when in the act of moulding a brick.
This part is made and fitted in the following manner.
At, or near each end of the stock, on each side, in the required positions, we
provide that the bearings for the mould, on each side of the stock, shall be of
circular shape, or rollers, or wheels may preferrably form the bearings; if the latter
are fitted each pair will probably be connected from side to side of the stock by an
iron or steel spindle which may revolve with the rollers, or wheels, in bearings
provided in the stock for the purpose, or the spindles may be fixed, and the rollers
or wheels revolve upon same.
The rollers, wheels, or circular bearings are fitted close up to the side of the
stock.
By reason of the circular form of the bearings no sand or clay can accumulate
upon same, (as upon the flat surface of the coach screws or other similar stock
fittings) whereby the gauge of the brick is altered, and the more or less rapid
destruction of the edge of the mould follows.
Further the rollers, or wheels, being free to revolve the bearing surfaces for the
mould is a constantly changing one thereby probably equalizing the wear of same
and consequently for a long time insuring the correct gauge of the bricks moulded
by means of our fittings.
The complete stock and fittings can be readily and easily secured to the table by
suitable screws or bolts and it is noted, the rollers, or wheels, and spindles can be
removed and quickly replaced by new, without destroying the other parts.
Dated this 25th day of March 1891.

Improvements in Brick Moulds, and the Stocks and Fittings used
with same.
We ROBERT WILLIAM JESSON of 17 Cranbury Avenue, Law Clerk, and
SIDNEY NICHOLS of 39 Northbrook Road, Builder, and JOSEPH ANDREWS, of
34 James Street Saint Mary's, Carpenter, all of Southampton in the County of
Hampshire, 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 :-
Our invention relates to brick moulds, stocks, and their fittings, and comprises
various improvements hereinafter described.
The main object of our invention is to provide cheap and durable brick moulds,
stocks, and fittings, for use in making bricks by hand.
Our complete apparatus consists of-first, a brick mould second, a stock with its
fittings.
In making a brick mould according to one form or modification of our invention
cach side of same, is cast in one piece the material probably being of malleable cast
iron, or steel, the upper and lower edges and ends of same are provided with a rib
or bead of a thickness corresponding to about three times that of the sides, more or
less, as desired, and of a width equal probably to about twice the thickness, and
champhered or bevelled off and dying away into the ordinary thickness of the sides;
further, a rib midway of the length of mould may be cast on the sides of same in a
vertical or diagonal direction whereby the sides are stiffened and strengthened.
The ends of mould will probably be of wrought iron or steel plate, the vertical
edges of same, fitting against the sides, being turned or angled into a direction
parallel with the sides, and to which they are riveted or otherwise fastened; or the
ends may be otherwise suitably connected to the sides thus completing the
mould.
The stock and "frog" will be cast in one piece and made of malleable cast iron
or steel.
In the accompanying drawing which serves to illustrate our invention
Fig. 1. is a sectional elevation of our improved stock and mould shewing same in
position on the moulding table L,
Fig. 2 is a plan in section of the stock and fittings on line A. B,
Fig. 3, is an outside elevation, and
Fig. 4, a plan on top of Fig. 3, and
Figs. 5, 6, and 7, are cross sections respectively on lines r, d, a, b, and e, f.
The parts marked J, represent the stock and those K, the mould.
Similar letters refer to similar parts in the respective views.
The bead at the upper and lower edges of the mould K, and the rib on the sides
of the mould are lettered respectively 7, and m.
One method of completing the construction of the mould, connecting the sides
by means of the end plates n, is shewn at o, but we do not limit ourselves to this
particular method of connection, the same for instance may be made by providing
tongues on the vertical edges of the end plates, which would pass through corre-
sponding holes in the side plates and then be turned on the outside of the sides, or
clenched on the latter, or any other suitable way of connecting the ends to the sides
may be adopted that may be found convenient and efficient.
The stock J. is cast in one piece with the "frog" M, and the swells and bosses
as shewn at i, i,j, j, the former provides increased bearing surface for the bolts P,
the latter take the holding down bolts or screws which secure the stock in position
on the moulding table L, the swells i, i, also strengthen the corners of the stock,
and both swells and bosses provide an increased bearing surface for the bottom of
the stock.

page_text: The essential feature of our invention applicable to the stock is that part of same
upon which the mould is placed and rests, as it would upon the coach screws or
other similar stock fittings (as ordinarily hitherto used for the purpose) when in the
act of moulding a brick. We shall hereinafter refer to this part of the stock as
the "rest or "rests."
"
3, 8,
According to the method we prefer to adopt in constructing these "rests
and t, t, we make and provide iron or steel bolts p, p, with circular or cheese
heads, t, these bolts are passed through the holes or bearings r,, provided in the
sides of the stock and circular nuts s, s, are screwed on the ends of the bolts on a
thread provided on same, the point of the bolt is then "upset" or slightly "burred"
over so as to fix the nuts on the bolts, each bolt with its nut s, is free to revolve in
its bearing r, so that whenever the mould is placed on the stock the result will
probably be that the bolts and consequently the "rests" will revolve (by reason
of the particular way in which a mould is always placed on a stock) whereby a
constantly changing resting surface for the mould is secured, thereby probably
equalizing the wear of the "rests" and consequently for a long time ensuring the
correct gauge of the bricks moulded by means of our invention.
"
Again by making the "rests of circular form little or no clay or sand can
accumulate upon same, as upon the flat surface of the coach screws or other similar
stock fittings, whereby the gauge of the brick is altered and the more or less rapid
destruction of the edge of the mould follows.
"
It is obvious that other methods of fitting the circular "rests for the mould
may be adopted, for instance, fixed spindles may be fitted in place of the bolts p, p,
and wheels or rollers may be arranged to revolve on the outer ends of same, or the
"rests
may be fixed to, or form part of the sides of the stock, but still be of
circular or semicircular form at the top part, should any one of these arrangements
be adopted, the advantage of having "rests for the mould which offer the least
surface and opportunity for the accumulation of sand or clay on same is secured,
but as hereinbefore stated we prefer to make the "rests of a circular form and
free to revolve in or upon the stock.
"
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. The improved brick mould consisting of the parts constructed and fitted in
manner as hereinbefore substantially described and illustrated in the accompanying
drawings.
2nd. A brick mould with malleable cast iron or steel sides, with ends connecting
same together thereby completing the mould, in manner as hereinbefore substantially
described and illustrated in the accompanying drawings.
3rd. The improved brick stock east in one piece in malleable iron or steel, as
hereinbefore substantially described and illustrated in the accompanying drawings.
4th. In a brick stock the particular method of constructing and fitting the
"rests
for the mould the essential feature being the circular form of same at
the top part as hereinbefore substantially described.
5th. A brick stock with revolving circular rests for the mould as hereinbefore
substantially described and illustrated in the accompanying drawings.
