PROVISIONAL SPECIFICATION.
Improvements in the Method of and in Apparatus or Machinery for
Pressing Bricks, Tiles, and the like.
We, RALPH TOWNSEND HUGHES, of 3 Roslyn Villas, Saltburn-by-the-Sea,
Brick Manufacturer, and JOHN GILL, of Holbeck Lane, in the City of Leeds,
Engineer, both in the County of York, do hereby declare the nature of this
invention, to be as follows:-
Our invention relates to improvements in the method of and in apparatus or
machinery for pressing bricks, tiles, and the like.
The object of our invention is to press bricks, tiles, and the like upon the sides
or in a horizontal direction, and not downward or in a vertical direction as
heretofore, so as to prevent the formation of arris upon the edges of same, and
to press them all to the same, or one uniform thickness.
According to our invention we employ one or more moulds or solid boxes capable of
being moved by hand or automatically in turn between presser blocks for obtaining
the said side pressing action, and afterwards moved away for discharging the pressed
material by hand or automatically.
The said presser blocks are operated by cranks and toggle mechanism, or by
levers and toggle mechanism from shafts mounted in the machine frame.
The said moulds or solid boxes are made with a solid top and bottom, and open
ends adapted to fit into which are slides which are automatically raised or lowered
or moved sideways so as to open or close the ends of the said boxes or moulds. The
said slides being down or closed when the pressing action is on, and raised or
moved away for the discharging action to take place. Or the said moulds or
boxes are provided with a moveable top and solid ends, and a loose bottom or plate
which is capable of being automatically raised for discharging the pressed article,
and lowered automatically after such discharge.
A cylinder carrying or provided with solid moulds or boxes as aforesaid may be
employed, and rotated by hand or automatically so as to bring the said moulds or
boxes in turn between the said presser blocks so as to obtain the said pressing and
delivery actions.
In some cases hinged doors with wheels, screws, and loose plates may be employed
in connection with the moulds or boxes to close the ends.
A spring or cushion arrangement is provided in connection with the shafts
operating the presser blocks, or in connection with the presser blocks themselves so
as to compensate for varying thicknesses of material and to press all to a uniform
thickness without arris.
The shafts for operating the presser blocks may be actuated by cams and runners,
or other suitable meaus.
The machine may be worked by hand or driven by power.

page_text: solid top A¹ and solid bottom A², with apertures in one or both sides for presser
blocks B to work through.
The said moulds or boxes A may be made in sections or segments jointed
together, or with removable liners for different sizes of bricks.
The said moulds or boxes A are provided or constructed with open ends G,
adapted to fit into which are slides H, which are automatically or manually raised
or lowered, or moved sideways so as to open or close the ends of the said boxes.
or moulds. The said slides H being down or closed when the pressing action is.
put on and raised or moved away for the discharging action to take place.
The said slides H may be formed in the shape of wedges, or otherwise.
For the purpose of manually opening and closing the ends of the moulds or
boxes A the slides H of the said moulds or boxes A are joined to racks J and J'
which gear with pinions K and K', these pinions K and K' normally gear with each
other, and the pinion K' can be put in or out of gear with the rack J¹ by a clutch
arrangement J³.
This arrangement is shown in Figs. 1 to 3, and the automatic arrangement is.
shown in Figs. 6 and 7. Referring to these figures the axle or shaft Bs has arms B*,
jointed to which are levers BB by means of connecting links B', the lever Be being
fulcrummed at B' upon a bearing B10 secured to the table of the machine, and joined
to the slide H of the mould or box A.
Upon the said axis or shaft B5 are fixed couplings or clutches B", with movable.
pieces B joined by lever mechanism B¹³ to a hand lever B pivoted at B1 to the
inachine frame.
The action is:-When the axles or shaft B is caused to turn by the action of
the quadrant wheel L, as hereinafter referred to, the levers B turn on their
axes B, and raise or lower the slides H according to the direction in which the.
said quadrant wheel is moved.
By means of the said hand lèver B, the coupling pieces B12 may be disengaged
from the fixed couplings B.
Referring again to Figs. 1 to 3. L is the quadrant wheel carried on the axle.
or shaft B (and having hand pins L) and by which the machine is operated.
On throwing over the quadrant wheel L the toggle, or its equivalent, mechanism
causes the presser blocks B to give their pressing action through apertures in the.
sides of the mould or box A, the slides H having previously been closed by the.
hand lever M, or simultaneously through the automatic apparatus described.
After the pressing action has taken place the slides Hare
raised by
hand through hand lever M or automatically as described with reference to.
Figs. 6 and 7, and the quadrant wheel reversed so withdrawing the presser
blocks B.
By means of the shape of the mould A and the pressing action each brick is
pressed to a uniform size, and thickness, and no arris is formed upon the brick, but
a perfectly clean edge in lieu thereof, which in bonding or building looks, and is
much smarter than bricks as pressed or made heretofore.
The bricks after being pressed are discharged end ways of the mould by means,.
see Fig. 2, of the pusher out N, which slides on a level with the bottom A² of the
mould or box A, and is joined by link Oto hand lever P pivotted at P¹ to a
bracket P2 upon the machine frame.
By operating the said hand lever the pusher N is caused to pass through the
mould or box A, so as to discharge the brick, and after such is easily and readily
withdrawn.
In Figs. 4 and 5. The crank shaft E is driven by pulley E¹ which is fast, the
other pulley E is loose upon such shaft.
The crank C of said shaft E are joined up to the links or toggle mechanism T to
which the pressure blocks B are connected.
Rods U carried by bearings V are joined to the toggle mechanism T, and have
between them and the toggle mechanism, spiral springs or cushions W for allowing
for varying thicknesses of material.

page_text: On operating the crank shaft E the presser blocks B through the mechanism
aforesaid press the brick in the manner set forth with reference to Figs. 1 to 3.
Or the said moulds or boxes A are provided with a movable top and solid ends,
or one solid end with small pusher out in centre and one loose end, and a loose
bottom or plate which is capable of being automatically raised for discharging the
pressed article, and lowered automatically after such discharge.
A cylinder or some similar arrangement carrying or provided with moulds or
boxes as aforesaid may be employed and rotated by hand or automatically so as to
bring the said moulds or boxes in turn between the said presser blocks so as to
obtain the said pressing and delivery actions.
In some cases hinged doors with wheels, screws, weights and loose plates may be
employed in connection with the moulds or boxes to close the ends.
A spring or cushion arrangement is provided in connection with the shafts
operating the presser blocks or in connection with the presser blocks themselves so
as to compensate for varying thicknesses of material and to press all to one uniform
thickness without arris.
The shafts or levers for operating the pressed blocks may be actuated by cams
and runners, or other suitable means.
The machine may be worked by hand or driven by power.
On comparing Figs. 10 and 11 with Figs. 8 and 9, the latter of which show
the old system and 10 and 11 our new system of pressing, it will be seen that no
arris, or deviation in the pressing, such as occurs by the system illustrated by
Figs. 8 and 9 can occur by the use of our new system.
We would have it understood that although the presser blocks are shown acting
within the moulds A in a horizontal direction, the moulds A may be turned so that
the presser blocks may act in a vertical direction, but still upon the sides of the
brick or the like.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:-
1. The hereinbefore described method, of pressing bricks, tiles, or the like, by
causing presser blocks to operate on the bricks, tiles, or the like until the clay or
material fills the box or mould to its full extent, the said mould or box being so
constructed that any variation in the quantity, size, or condition of the brick or
material put into the box or mould is adjusted by the depth of the panel or indent,
substantially as set forth.
2. The construction and arrangement of the box or mould A, the shape formation
and action of which in combination with presser blocks B ensures each brick, tile or
the like being pressed to one uniform thickness and size, and free from arris or
rough edges, such as shown and described.
3. The combination and arrangement of parts forming our invention for
pressing bricks and the like, to prevent the formation of arris or rough edges,
and all variation in size except in depth of panel or indent, substantially as
set forth.
4. In apparatus or machinery for pressing bricks, tiles, or the like, the use or
combination of a box or mould having movable ends, actuated by hand or
automatically, substantially as and for the purposes set forth.
