PROVISIONAL SPECIFICATION.
Improvements in Brick Making Machines.
I, THOMAS CONSTANTINE FAWCETT, of The Whitehouse Engineering Works,
Hunslet Road, Leeds, in the County of York, Machine Maker, do hereby declare
the nature of this invention to be as follows:-
This invention refers to brick making machines more particularly to that class
described in Breething's Specification No. 74329. In this machine bricks are
formed in sockets in a revolving table and it is necessary for the newly formed
bricks to be scraped or strickled on the upper surface and this is at present
accomplished by an attendant. The object of iny invention is to strickle the brick
automatically and this I accomplish by means of a moving strickler composed of
wood or other suitable material. The advancing point of the strickler is formed
with one or more angles or it may be semicircular, but it is caused to scrape or
trickle the upper surface of the brick as the table revolves. The strickler may
be operated by a tappet on the crank shaft or from any other convenient moving
part of the machine.
Dated this 2nd day of July 1894.

Improvements in Brick Making Machines.
I, THOMAS CONSTANTINE FAWCETT, of The Whitehouse Engineering Works,
Hunslet Road, Leeds, in the County of York, Machine 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 refers to machines for making sand faced bricks more particularly
to that class of machine described in Breething's Specification of Patent No. 743291.
In this machine bricks are formed in sockets formed in a revolving table and it is
necessary for the newly formed bricks to be scraped or strickled on the upper
surface, which is at present accomplished by an attendant.
The object of my invention is to strickle the brick automatically and this
I accomplish by means of a moving strickler composed of wood or other suitable
material.
The advancing point of the strickler is formed with one or more angles or it may
be semicircular, but it is caused to scrape or strickle the upper surface of the brick
as the table revolves. The strickler may be operated by a tappet on the crank
shaft or from any other convenient moving part of the machine.
In order that my invention may be more fully understood and readily carried
into effect, I will describe the accompanying sheet of drawing, reference being had
to the figures aud letters marked thereon, wherein Fig. 1 is elevation and Fig. 2
plan of my improved mechanism.
A represents a portion of a revolving table provided with moulding boxes B
which is common in Breething's brick making machine. A portion of the side

page_text: of the pug-mill is shewn at C, but as it forms no part of my present invention
no further reference need be made to it. My invention refers principally to
apparatus for scraping the top surface of a brick after it has been lifted from
the moulding box. D represents a brick lifted from its mould in the table, and
as the said table revolves the brick passes underneath the angular scraper E.
This scraper has a backward and forward motion imparted to it for the
purpose of traversing over and scraping the surface of the brick. The means
I employ for imparting a backward and forward traversing motion to the scraper is
as follows:-The scraper is connected to the lever arm F, the front end of which
carries a bowl G made to travel in a double cam groove H and I divided by
a flange J, therefore when the lever arm Fis passing over the brick to scrape it in
the direction of arrow a, the bowl G rides underneath the flange J and when the
said bowl arrives to the end of the groove, the bowl lifts up the hinged finger L and
gets upon the top of it on its return journey, whereby the said lever arm and
scraper have the necessary backward and forward motion for scraping the brick.
In order that the scraper itself may be cleaned 1 employ another triangular plate M
fixed to the end of bell-crank lever N weighted at 0. This cleaning scraper Mis
so placed with regard to the scraper E that when the bowl G is riding upon the
inclined plane P the scraper E rubs against the cleaning scraper M whereby
the clay is removed therefrom. The mechanism to give oscillating motion to the
lever arm F is obtained by means of cam Q (see Fig. 3). This can is fastened upon
the shaft working in the centre of the pug-mill C.
The guide rod S and short lever T are employed to steady and support the
forward end of lever F.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. The use and employment of an automatic scraper such as E employed
and operating in the manner and for purposes substantially as shewn and described
.herein.
Secondly. The combination of scraper E with cleaning scraper M.
