PROVISIONAL SPECIFICATION.
Improvements applicable to Brick Making Machines.
JOHN KAY, of Accrington, Brickworks Manager, JOHN LOBLEY, of Ramsbottom,
Tin and Copper Smith, and HENRY BUNKALL, of Baxenden, Brickmaker, all in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
It is applicable to brickmaking machines for shaping and pressing bricks.
Its object is to automatically sprey each brick with oil or other compound
while passing from the shaping mould to the pressing mould.
The accomplishment is by means of a cistern or cisterns fixed above machines or any
other convenient place and the oil or other compound conveyed conveyed to each side
of machines through pipes and spreyed on each brick automatically by hot dry air
hot moist air, cold air or steam. The advantages claimed are to prevent loose
particles adhering to the finished brick and so a better appearance obtained.
This appearance, facing or skin on the brick makes it more impervious to water
and consequently more proof against wet weather. Lubrication of the bottom
piston plate of mould with outlets so as to allow the escape of dirt at the bottom
instead of delivery plate at the top and thus minimising the wear and tear of all
the working parts of the mould and the piston plate. Prevention of the brick
adhering to piston which causes frequent stoppages of machine.

Improvements applicable to Brick Making Machines.
We, JOHN KAY, of Blackburn Road, Accrington, in the County of Lancaster,
Brickworks Manager, JOHN LOBLEY, of Ramsbottom, in the County aforesaid, Tin
and Copper Smith, and HENRY, BUNKALL, of 14, Belgrave Street, Baxenden, in the
County aforesaid, Brick Maker, 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 to improvements in appliances designed for application to
and use in combination with brickmaking machines being specially adapted to
such as are known as semi plastic re-press machines. The object of the invention
and the apparatus is to automatically spray each brick with oil or other lubricat-
ing compound during the process of manufacture and whilst passing from the

page_text: shaping mould to the pressing mould. The invention consists of a supply cistern
with pipe or pipes leading to a point where the brick is to be sprayed and also a
pipe or pipes through which is forced a supply of hot dry air, cold air, or.steam, which
sprays the lubricant on to the brick, and the spray is automatically" cut off
or opened" by means of a slide plate or valve controlled from the crank of the
machine.
"
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying draw-
ings, in which

improvements applied to it.

According to this invention we employ a cistern or tank 1 for containing oil
or other lubricating compound. The cistern or tank 1 is supplied by pipe 2 from
a main supply cistern or tank not shewn, but which may be connected with one
or more machines there being a tap or valve 3 between the pipe 2 and each
cistern or tank 1 so that the flow of lubricant can be controlled and regulated;
The cistern or tank 1 has preferably a glass covered hole 4 through which the
contents can be seen, and at or near the bottom of the tank is a preferably funnel
shaped outlet 5 communicating with the pipe 6 which extends to and enters the
air pipe 7. The air pipe 7 is supplied with hot, cold, dry or moist air from the
main supply pipe 8 along which a current is forced by means of a fan or other
device and the orifice or nozzle of the lubricant pipe 6 and the air pipe 7 are at
a point directly between the first mould 8* and the repress mould 9, the lubricant
pipe 6 being inside and, near the top of the air pipe 7, the latter resting on the
cut off or delivery table 10.
In the air pipe 7 is a slide or valve 11 consisting of a sheet of metal.cutting
the pipe 7 and free to be moved up and down in the slide bed 12 and in such
sheet of metal 11 is a hole 13 so that when the slide 11 is raised, the hole 13
allows the air to pass along the pipe 7 and to blow the lubricant as it drops from
the end of the pipe 6 in the form of a spray onto the brick when passing from
the mould 8 to the re-press mould 9.
The intermittent spraying action is obtained by operating the slide 11 from the
rising and falling cross head 14 in the following manner. Attached to the cross
head 14 is a rod or bar 15 suspended or connected to which is the rod 16. the
lower end of which is cranked and passes under and together with a spring here-
after referred to normally supports the slide 11 so that as the cross head 14 rises
the cranked lower end of the rod 16 takes up with it the slide 11 and the air
pipe is opened by the hole 13 being inside the pipe 7 and the air blows the
lubricant in the form of a spray onto the brick which at this time is passing from
the mould 8 to the re-press mould 9. When the cross head 14 falls it takes with
it the rod 16 but as it is desirable that the spraying process should not at once
cease the spring 17 is provided and the end of this spring holds up the slide 11
and the air pipe 7 remains open until such time as the cross head 14 descends
so far that the cranked end of the rod 16 comes into contact with the head 18
of the double headed pin or link 19 which passes through holes in the spring 17
and the cranked rod 16. When the cranked end of the rod 16, meets the head 18
then the other head 20 of the pin or link 19 pulls down the spring 17 and the
slide 11 is allowed to fall and the air pipe 7 is closed or cut off" (see Fig. 3).
The improved apparatus may be placed on one or both sides of the machine as
desired.

invention and in what manner the same is to be performed; we declare that what
we claim is:-
