Improvements in or relating to Brick Making or like Presses.
We, JOHN BERRY, of Woolpit, Bury-St.-Edmunds, in the County of Suffolk, Brick
Manufacturer, GEORGE BEARDSALL, of 7 Hope Drive, The Park, in the Borough of
Nottingham, Engineer, and THE IDEAL BRICK PRESS SYNDICATE LIMITED, of 38 Castle
Gate, in the Borough of Nottingham, Brick Press Manufacturers, do hereby declare
the nature of this invention to be as follows:-
This invention relates more particularly to presses for compressing clay or other
plastic materials into bricks or the like for building or other purposes, but it may
also be generally applied to presses employed for compressing plastic materials into
moulds.
In carrying out this invention the framing of the press may be formed by a base
plate, on which are secured two end standards connected to each other by cross stays.
Between the two standards is a preferably horizontal plate which forms the botton
of the mould.
The bottom of the mould corresponds in plan to the size and shape of the brick in
plan, and it is preferably mounted on a pillar of a suitable height, the said pillar being
secured to the base-plate.
Above the bottom of the mould is a vertical casing which forms the sides of the
mould, the interior of this casing corresponds to the size and shape of the brick in
plan, and it is alternately lowered so that it fits over the bottom of the mould and
raised clear of it by the following arrangement
Above the casing is a horizontal shaft carried in bearings secured to or formed in
the two standards, mounted on this shaft are one or more cams in peripheral contact
with antifriction rollers or tappets secured to vertical extensions of the casing, or
vertical guides secured thereto.
The upper end of the vertical extension or guides may be provided with shafts or
pins working in a guide plate secured to the two standards; the casing may also be
provided with extensions working in vertical guides on the standards.
Working in the interior of the casing is a ram operated by one or more cams on
the horizontal shaft, these cams are in peripheral contact with anti-friction rollers
pivotted on or in the upper end of the ram. The ram may also at this point be
provided with lateral extensions working in vertical guides in the standards.
The action of the press is as follows:
When the casing is raised clear of the bottom of the mould, a piece of clay or other
material is placed on it, the casing then descends until it encloses the piece of clay
and the bottom of the mould, the ram is then depressed and the clay compressed
into the shape of the mould which is formed by the said bottom, casing, and ram.
The casing is then raised until it is clear of the brick, whilst the latter is held between
the ram and the bottom of the mould, the ram is then raised and the brick removed
and replaced by a fresh lump of clay.
With this arrangement we are enabled to compress what is known as wet clay, and
remove it from the mould after compressing it without damage.
Lumps of clay or material are fed on to the bottom of the mould from a longi-
tudinal platform in the front, and removed when compressed on to a similar platform

page_text: or endless conveyor band at the rear. This may be effected by a reciprocating slide
on the front platform which pushes a lump of clay, previously placed on the platform,
on to the bottom of the mould, this lump of clay at the same time pushes the com-
pressed brick on to the platform or band, at the rear. The reciprocating slide may
be actuated by a link and lever arrangement operated by a cam on the horizontal
shaft, or a crank pin on a wheel secured thereto, the said pin being arranged to
engage with and tip the first lever of the mechanism, each revolution of the horizontal
shaft.
As each lump of clay passes from the platform to the mould, it passes between
a pair of horizontal lubricating rollers. The lower r ller is mounted in bearings
in a horizontal trough in or near the inner edge of the front platform. the said
trongh being partially filled with oil or other suitable lubricant, in which the roller
rotates. The upper roller is mounted is slotted bearings above the lower roller and
is supplied with a like lubricant from a trough arranged parallel to the roller. The
lubricant from this trough may be fed on to the roller by a longitudinal strip of
absorbent material or by intermediate feed rollers or other convenient means.
The casing of the mould may be lubricated by placing the lubricant in the casing
above the ram, the latter being packed so as to prevent the escape of oil too
rapidly.
The press described is adapted to compress one brick at each operation, but by
duplicating the parts which form the mould, two or more bricks may be compressed
at one operation. In some cases also the bottom of the mould may be arranged
so as to receive a movement simultaneously with but in the reverse direction to the
ram.

Improvements in or relating to Brick Making or like Presses.
We, JOHN BERRY, of Woolpit, Bury-St.-Edmunds, in the County of Suffolk,
Brick Manufacturer, GEORGE BEARDSALL, of 7, Hope Drive, The Park, in the
Borough of Nottingham, Engineer, and THE IDEAL BRIOK PRESS SYNDICATE,
LIMITED, late of 38, Castle Gate, now of Peas Hill Rise, both in the Borough of
Nottingham, Brick Press Manufacturers, 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 :-
This invention relates more particularly to presses for compressing clay or other
plastic materials into bricks or the like for building purposes, but it may be
generally applied to presses employed for compressing plastic materials into moulds.
The invention will be best understood by reference to the accompanying drawings
in which
Fig. 1 is a front (partly sectional) elevation with parts removed, and
Fig. 2. a vertical cross section taken on the line X X of Fig. 1 of a brick press
constructed according to our invention.
Fig. 3 is a horizontal section taken on the line Y Y of Fig. 1.
Figs. 4, 5, 6, 7 and 8. are sectional elevations, showing those parts of the press
which form the mould in different operating positions.
Like letters indicate like parts throughout the drawings.
The press as shown in the drawings is constructed to press two bricks at one
operation, but it may be constructed to press one, two or more as desired.

page_text: In carrying out this invention, the framing of the press is formed by a base
plate A (see Figs. 1, 2 and 3) on which are mounted two standards A' A which
are connected to each other at the upper end by a cross stay A³.
The base of each brick mould is formed by a fixed platform B, (see Figs. 1 and 2)
this platform corresponds in plan to the size and shape of the brick in plan.
Each platform B is mounted on a pillar B' secured to or formed with the base B',
and the latter fits into a packing box B secured to the base plate A.
The packing placed in the box B between the base B' and the bottom of the
said box to allow of a slight downward movement of the platform B under excessive
pressure, may consist of a layer of timber B and a layer of india-rubber B³, but
this may be varied to suit different requirements.
The upper ends of the two pillars B' may be connected together and be prevented
from moving laterally by vertical extensions C of the packing box B3. The upper
ends of these extensions Care provided with slots C' in which studs C secured to the
pillars B engage.
Above the platforms B is a hollow vertical casing D which forms the sides of the
moulds, the interior of this casing is subdivided by a partition D' (see Figs. 1 and 3)
and the two interior chambers correspond in plan to the size and shape of the brick
in plan, and fit over the two platforms B. The casing D is alternately raised clear
of the platform B as shown in Figs. 1, 2 and 4 and lowered on to the platforms as
shown in Figs. 5 and 6 by the following arrangement.
Above the casing D is a horizontal shaft E (see Figs. 1 and 2) carried in
bearings E secured to <r formed in the standards A¹ A2; mounted on this shaft is
a cam F in peripheral contact with a tappet F', this tappet F being provided with
a vertical stalk or spindle F which slides longitudinally in a bearing F secured in a
slot in the cross stay A³, and is also connected to the casing D by bows or connecting
links D'.
To prevent the casing D from moving laterally, at the sides are shoes or
extensions D³ (see Fig. 1) which work in vertical slides G secured to the
standards A A³.
Fitting in the interior of each part of the hollow casing D (see Figs. 1, 2 and 3)
is a ram or stamp-die H both of which are connected to or formed integrally with
the cross head H. This cross-head is provided with blocks or shoes H to work in
the vertical slides G and an antifriction roller H pivotted in the cross-head.
The stamp dies H are depressed by the cam F acting on the antifriction roller H³,
and the said cam thus performs two operations, that is, it raises and lowers the
casing 1) through the arrangement described, and also depresses the stamp dies.
If preferred however independent cams or sets of cams may be employed for
raising and lowering the casing D, and depressing the stamp dies H.
The stamp dies H (see Figs. 1 and 2) are raised by cams II on the shaft E,
each cam is in peripheral contact with a tappet 1 formed with a vertical stalk or
spindle sliding longitudinally in a bearing I secured in a slot in the cross stay A.
Each tappet 1 is also connected to the cross-head H' of the stamp dies H by bows
or links 14.
The action of the press is as follows:-
When the casing D is raised to the position shown in Figs. 1, 3 and 4 a wire
cut brick, piece of clay or other material J (see Fig. 4.) is placed on the
platform B, the casing D then descends into the position shown in Fig. 5 and encloses
the clay J, the stamp die H is allowed to fall and is then depressed into the position
shown in Fig. 6, and the clay J compressed into the mould which is formed by
the said platform B, casing D, and stamp-die H.
The casing D is then raised into the position shown in Fig. 7 whilst the compressed
brick J is held between the stamp-die H and platform B, the stamp-die H is then
raised together with the casing D into the position shown in Fig. 8. The compressed
brick is then removed and replaced by another unpressed brick or piece of clay
and the operation repeated.
With this arrangement and node of operating the several parts, we are enabled

page_text: to compress what is known as wet clay and remove it from the mould after
compressing it, without damage.
The unpressed bricks or lumps of clay are fed on to the platforms B from a
table K (see Figs. 2 and 3) the upper surface of which is level with the upper
surface of the platforms B.
Mounted on the table K is a skeleton frame L which is reciprocated between
guides K secured to the platform K. This frame L is formed to enclose two bricks
or lumps of clay which are placed therein, and the said bricks or lumps of clay are
moved by the action of the frame I on to the platforms R.
The inner end of the frame L is provided with doors L' L' (see Figs. 2 and 3)
which are hinged to the frame at L, these doors engage with and move the
compressed bricks from the platforms B on the inward movement of the frame L.
whilst on the outward movement of the frame, the doors I open and leave the
unpressed bricks which were in the frame L, on the platforms B.
The compressed bricks may be moved on to an endless conveyor band, or on to a
board ready to be carried away.
The frame L is reciprocated by the following means. It is connected by a link K'
to an arm M secured on the shaft M', this shaft is carried in bearings M' secured
to the base plate A.
The shaft M is reciprocated by a cam N (see Fig. 1) on the shaft E through a
lever N which is pivotted at N to the standard A', the upper end of the lever N¹ is
provided with an antifriction roller N in peripheral contact with the cam, and its
lower end is connected by a link N to an arm N secured on the shaft M.
Each brick or lump of clay as it is moved inwards on the platform by the frame L
towards the platforms B passes between and is lubricated on the top and bottom by
lubricating rollers O and P (see Figs. 2 and 3). The upper roller O'is mounted in a
trough O' provided with a slot or opening in its base, through which the surface of
the roller projects. The roller O fits accurately in the slot in the base of the
trough Obat to prevent the escape of oil when the roller is raised by the brick in
its passage, a porous covering 0 is secured above the roller O, through which the oil
may gradually percolate.
The lower roller P is mounted in a trough P' let into an opening in the table K.
The upper surface of the roller P is adjusted so as to be flush with or slightly
above the surface of the table K.
The interior of the casing D is lubricated by placing oil in the said casing above
the stamp-dies H', and to prevent this oil from escaping the stamp dies are packed
at H'.
The cam shaft E is connected to the main shaft Q by a toothed wheel R on the
former engaging with a pinion R' on the latter.
The main shaft Q is mounted in bearings Q1 secured to the standards A' A³ and is
provided with driving pulleys Q and fly wheel, which latter is not shown.
To allow of the rapid escape of the uir enclosed in the casing D, in order that
the fall of the stamp-lie may not be retarded, openings may be formed in the sides of
the casing D preferably at a point just above the height of the brick when in the
casing.
These openings preferably communicate with the atmosphere through vertical
passages formed in the walls of the casing D. These passages may be provided
with stop couks or valves in order that the fall of the stamp-die may be regulated
by adjusting the size of or closing the air outlets.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A brick or like press in which the four sides of the mould are moved clear of
the brick while the latter is held between the top and bottom of the said mould
substantially as described.
2. A brick or like press in which the four sides of the moulds are raised while
