PROVISIONAL SPECIFICATION.
Improvements in Brick Making Machinery.
I JAMES ALEXANDER MATTHEWS of 104 Haslingden New Road Blackburn in the
County of Lancaster Brick Maker, do hereby declare the nature of this invention to
be as follows:-
The object of this invention is to so time the speed of the working parts of the
machine as to produce more work within a given time.
Heretofore the slow speed necessary when pressing the brick has been maintained
throughout all the movements of the machine."
I accelerate the speed between the sucessive pressings of alternate bricks made.
For purpose aforesaid according to this my said invention I employ duplicate pairs
of fast and loose pulleys of different diameters one pair driving the presser, the other
pair driving the main parts of the machine the straps are controlled by strap forks
connected by a horizontal bar, the opposite end of which is operated by means of two
tappet or projecting surfaces on the upright shaft so that as the latter rises and falls
the tappet surfaces alternately act on the end of the strap fork bar and change the
strap from the smaller to the larger diameter pulleys, accordingly as to whether the
machine is pressing or feeding.

I, JAMES ALEXANDER MATTHEWS of 104 Haslingden New Road, Blackburn, in the
County of Lancaster 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 :-
The object of this invention is to so time the speed of the working parts of the
machine as to produce more work within a given time.
Heretofore the slow speed necessary when pressing the brick has been maintained
throughout all the movements of the machine.
I accelerate the speed between the successive pressings of each brick made.
For purpose aforesaid according to this my said invention I employ duplicate pairs
of fast and loose pulleys of different diameters one pair driving the presser, the other
pair driving the main parts of the machine, the straps are controlled by strap forks
connected by a horizontal bar, the end of which is operated by means of two tappet or
projecting surfaces on the upright shaft so that as the latter rises and falls the tappet
surfaces alternately act on the end of the strap fork bar and change the strap from the
smaller to the larger diameter pulleys, according as to whether the machine is pressing
or feeding.
Such being the nature and object of my said Invention, the following is a complete
description of same, reference being had to the accompanying drawings forming a part
of this specification.
Fig. I is a front elevation of my improved machinery.
Fig. 2 is a side elevation of same.
The several other views on sheets 1 and 2 are plans and elevations of parts seperately
or details.
For purpose aforesaid according to this my said invention I employ duplicate pairs
of fast and loose pulleys, 1, 1 and 2, 2 of different diameters, the pair 2, 2 drive the
presser, the pulleys 1, 1 drive the main parts of the machine.
The straps are controlled by strap forks 3, 4, connected by horizontal bar or bars 5,
the horizontal bar is connected at one end by an arm or arms 6 to the connecting
rod 7 on the main driver or fly wheel 8 of the machine.
The horizontal bar 5 is operated by two tappet or projecting surfaces 9. 10 on the
upright shaft or connecting rod 7 so that as the latter rises and falls through the
rotation of wheel 8, the tappet surfaces 9, 10, alternately act on the one side or other of
the looped end 11 of the bar 6, which turning on its fulcrum 64 moves the horizontal
bar 5 to the right and left and changes the straps 12, 12ª by means of the strap
forks 3. 4, from the fast pulley 1ª to the loose pulley 1 and from the loose pulley 2 to
the fast pulley 24 and vice versa.
It will thus be seen that the strap 12 is on the fast pulley 1 at the same time that
the strap 12 is on the loose pulley 2 and vice versa.

page_text: To stop the machine I employ arms 6 as illustrated in elevation on Sheet 2, plan
views of the same being shewn on Sheet 1 and duplicate horizontal bars 5, 5, the
link 11 being made to open and close, and working similar to a pair of scissors or
tongs, so that the lower arm 6 moves the lower horizontal bar 5 to the right and the
upper arm 6 moves the upper horizontal bar 5 to the left, at the same time, thus the
strap will be on the loose pulley 1, and the strap 12 will be on the loose pulley 24
and the machine will be stopped.
The two arms or links I can secure together by means of a ring or hook 13 and the
loop 11 will be complete again.
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;
In machines for pressing and making bricks the employment of duplicate driving
pulleys, and strap fork mechanism operated by and in combination with the connecting
rod and tappets such as herein described and substantially as illustrated by annexed
drawings.
