IMPROVE- MENTS IN BRICKMAKING MACHINERY
Year: 1876

page_text: LETTERS PATENT to Henry Ward, John Ward, and William Ward, the
younger, all of Leeds, in the County of York, for the Invention of "IMPROVE-
MENTS IN BRICKMAKING MACHINERY."
aled the 26th May 1877, and dated the 2nd December 1870.
PROVISIONAL SPECIFICATION left by the said Henry Ward, John Ward, and
William Ward at the Office of the Commissioners of Patents on the 2nd
December 1876.
HENRY WARD, JOHN WARD, and WILLIAM WARD, the younger, all of Leeds, in
the County of York. "IMPROVEMENTS IN BRICKMAKING MACHINERY."
Our Invention relates to machinery or apparatus for forming bars of plastic clay
and in cutting the samo to lengths preparatory to the moulding operation, and is
particularly applicable to the machine for which Letters Patent were granted to us
bearing date 8th July 1875, No. 2455.
Our Invention may be also applied to other brick machines.
Between suitable framework we mount one or more flanged drums of any suitable
width between the flanges to suit the brick to be moulded. Above cach drum, and
of such a width as to fit between the flanges, we provide a pressing roller, which is
mounted in bearings adjustable in a vertical direction on the framework; this
adjustment is for regulating the quantity of clay preparatory to its being deposited
in the brick mould, whereby the size of the brick may be regulated. To the drums
and pressing rollers is imparted an intermittent rotary motion through a ratchet
wheel and pawl, or their equivalents, actuated by means of a crank, eccentric, or
their equivalents; this intermittent rotary motion is made adjustable, so that any
convenient length of bar clay may be formed to suit the size of the mould on the
brick machine.
The bar of clay passes from between the rollers on to a table, where it is cut to
length by a knife actuated by the brick machine or by the aforesaid bar-formning
apparatus; after being cut off it is conducted to the mould, and deposited therein by
the ordinary means employed for dry and semi-plastic clay.
The plastic clay is fed through a hopper to the bar-forming apparatus or machine,
and when required a worm or other ordinary micans may be applied within the
hopper for forcing the clay between the rollers and drums.
P CAL

page_text: Our Invention further consists as follows:-With reference to our herein-before
mentioned Patent, No. 2455, 1876, instead of moving the box or measure con-
taining the clay to be pressed by means of a crank can or its equivalent, we
employ a steam cylinder and piston provided with a connecting rod, which we
attach to the box or measure. By the admission of steam into the cylinder on one
side or the other of the piston, the box or measure may be moved backwards and
forwards in the same manner as when the crank cam or its equivalent are
employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Ward, John Ward, and William Ward in the Great Seal Patent
Office on the 26th May 1877.

DESCRIPTION OF DRAWINGS.
Figure 1 is a side elevation, and Figure 2 a front elevation.
a is the framework, between which is mounted one or more flanged drums b,
keyed or otherwise fastened on the shaft c, carried in the bearings d on the frame-
work a. Above each drum b is a pressing roller c of such a width as to fit between
the flanges of the drum or drums b; this pressing roller c is mounted on the
shaft g, carried in adjustable bearings h, provided with the carriage i. The adjust-
0

page_text: ment is effected by the screws working into the nuts / provided on the carriages i.
The screws may be caused, when required, to rotate right or left by means of the
bevel gearing, actuated by the attendant through the shaft m. By this movement
right or left the nuts are caused to rise or lower, and with them the pressing
roller. e, for the purpose of adjusting or regulating the quantity of clay preparatory
to being deposited in the brick mould. n is the driving wheel of the brickmaking
machine, described in our herein-before mentioned Patent; from which a rotary
intermittent motion is imparted to each flanged roller b by means of the ratchet
wheel o through pawl p, lever q, rod r, coupling 8, and crank pin t, which is
attached to. the driving wheel n by ordinary means. When required, this rotary
intermittent motion may be made adjustable, so that any convenient length of bar
clay may be formed to suit the size of the mould on the brick machine.
The bar clay passes from between the rollers b and c on to the table u, where it
is cut to length by a knife actuated by the. brick machine or by the aforesaid bar-
forming apparatus; it is afterwards deposited by ordinary means in brick moulds..
vis the hopper into which the clay is first thrown, and from which it is fed to the
bar-forming apparatus.
The flanged roller bänd pressing roller ce are caused to rotate by means of the spur
wheels w.
Having now described the nature of our said Invention for "Improvements in
Brickmaking Machinery," and shown by Drawings how the same may be carried
into practice, we would have it understood that we do not limit ourselves to the
exact details or configuration of the various parts we have explained and shewn,
as the same may of course be varied or modified without in any way departing
from our Invention, but what we do claim and desire to be secured to us by Letters
Patent.is,―
First. The arrangement and application of flanged roller or rollers b in com-
bination with adjustable roller or rollers e, and parts connected therewith, forming
the machinery or apparatus whereby bars of plastic clay are prepared or made pre-
paratory to being used for the formation of bricks, substantially as herein set forth.
Second. The means employed. for cutting the bars of plastic clay to length, sub-
stantially as and for the purposes herein set forth.
Third. The application of a steam cylinder for the box or measure-containing the
clay to be pressed, substantially as herein set forth.

In witness whereof, I, the said Henry Ward, for myself and on behalf of the
said John Ward and William Ward, the younger, have hereunto set my
hand and seal, this Twenty-third day of May, in the year of our Lord One
thousand eight hundrod and seventy-seven.
