tion and use, which are as follows:-I employ a cylindrical table or
drum with a series of moulds therein, provided with moveable blocks or
stops to form bottoms or backs to the moulds and for forcing out the
moulded clay or brick forms somewhat similar to what is described in
the Specifications of Patents referred to. This table is mounted on a
vertical shaft, and intermittent motion is given to it by peg plate and
tappet wheel; or instead of the peg plate and tappet wheel I may work
the table or drum by a crank on the main shaft with a connecting rod,
and a catch or pawl acting on a notch plate fixed on the table or drum
shaft. The feeding plunger is worked by a crank pin on the eccentric
plate or a tappet wheel fixed on the main driving shaft, and this eccentric
or tappet also operates a lever which works a presser, a hopper being
provided for supplying the clay or brick earth either as usual or as
herein-after described; or instead of the shafts being vertical this machine
may be constructed so that the shafts are horizontal with the presser,
working either above or under the moulds, or at an angle or inclination
to the vertical as most convenient. Also I may work the presser by rod
connected to a crank fixed on the main shaft.
Secondly. In the construction and use in connection with brick-making
machines of a hopper having a casing or space for the reception of steam
or hot water to keep the sides of the hopper hot, and so prevent the
adhesion of the clay or other material.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Scholefield in the Great Seal Patent
Office on the 15th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
SCHOLEFIELD, of Leeds, in the County of York, Engineer and Machine
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of January, in the year a
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Richard Scholefield, Her special
licence that I, the said Richard Scholefield, my executors, adminis-

page_text: trators, and assigns, or such others as I, the said Richard Schole-
field, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and in all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN BRICK-MAKING MACHINERY," upon the condition
(amongst others) that I, the said Richard Scholefield, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Scholefield, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement and accompanying Sheet of Drawings,
that is to say :—
This Invention relates to that class of machinery for which Letters
Patent were granted to me, dated August 25th, 1868, No. 2636, and
July 15th, 1870, No. 2002 respectively, and the present improvements
consist,―
Firstly. In new combinations and arrangements of parts contained in
the Patents referred to so as to simplify such machines in their construc-
tion and use, which are as follows:-I employ a cylindrical table or
drum with a series of moulds therein, provided with moveable blocks or
stops to form bottoms or backs to the moulds and for forcing out the
moulded clay or brick forms somewhat similar to what is described in
the Specifications of Patents referred to. This table is mounted on a
vertical shaft, and intermittent motion is given to it by peg plate and
tappet wheel; or instead of the peg plate and tappet wheel I may work
the table or drum by a crank on the main shaft with a connecting rod,
and a catch or pawl acting on a notch plate fixed on the table or drum
shaft. The feeding plunger is worked by a crank pin on the eccentric

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation, and Fig. 2 a plan of my improved brick-making
machine. A is a cylindrical table or drum mounted on a vertical shaft B,
in which table are a series of moulds C provided with moveable blocks
or stops D similar to those described in the Specifications referred to,
which blocks or stops serve for the double purpose of forming bottoms
or backs to the moulds, and for forcing the moulded clay or brick forms
out of the moulds. Intermittent motion is given to the table or drum A
by means of the crank pin F on the main driving shaft G, and connecting
rod H, which operates the catch or pawl J, and causes the same to act
on the notches or pegs K fixed on the drum. L is the feeding plunger
worked from the main driving shaft G by means of the crank pin F,
which by means of the connecting rod M works the lever N, which
operates the presser O. P is the hopper for supplying the clay or brick
earth, the construction of which forms the second part of my Invention..
It is provided with a casing or space for the reception of steam or hot
water, which keeps the hopper hot, and thus prevents the adhesion of
clay or other material.
Figs. 3 and 4 shew a machine of slightly different construction, the
drum A being mounted horizontally on the shaft B, C being the moulds
and D the moveable blocks or stops. Intermittent motion is communi-
cated to the drum from the crank pin F (on the shaft G) and rod and
catch H, which acts on the peg plate K fixed on the shaft B. The
feeding plunger L is worked from the shaft G by means of the crank
pin F. The connecting rod M works the lever N, which operates the
presser O. P is the hopper for supplying the clay or brick earth. I may
apply a T shaped guide R for bringing the dies exactly opposite the
plunger, which guide slides in the brackets S. A pin U on the plunger
