IMPROVEMENTS IN MACHINERY FOR THE PRESSING OF BRICKS, COAL, PEAT AND SIMILAR SUBSTANCES
Year: 1884

page_text: I WILLIAM JOHNSON of Leeds in the County of York, Brick Manufacturer do
hereby declare the nature of said Invention for "IMPROVEMENTS IN MACHINERY
FOR THE PRESSING OF BRICKS, COAL, PEAT AND SIMILAR SUBSTANCES" to be as
follows:-
The object of my Invention is to so construct a pressing machine as to be able to
exert a greater amount of force at the same time simplifying the construction of
the machine by reducing the number of working parts between which friction is
produced, thereby also reducing the cost of the machine.
The machine consists of a standard or upright of ordinary construction. In
front and fitted so as to slide freely is a carriage in which is mounted the plunger
or block; and to this is attached the "former" or pressing plate. A driving shaft
is provided at the back of the machine in suitable bearings, and is geared into a
crank shaft transmitting motion thereto through a pinion and spur wheel
Now in my improvements in order to impart the required motion to the carriage
carrying the plunger I employ an oscillating beam coupled to the carriage by a
short connecting rod. Through the beam the required vertical reciprocating motion
is imparted to the plunger, the beam deriving its oscillating movement from the
herein before mentioned crank shaft through a connecting rod.
I also derive the required motion for pushing forward the brick or other
substance to be pressed from the crank shaft, through a bell crank lever; and the
motion for lifting or forcing out the form, after being pressed, from a suitable cam
or eccentric also on the crank shaft actuating a suitable lever arrangement.

And in order that my Invention may be more completely understood reference

DESCRIPTION OF DRAWINGS.
Fig. 1 is a part sectional elevation Fig. 2 a plan Fig. 3 a front elevation and
Fig. 4 a back elevation of a "machine for pressing bricks, coal, peat, and similar
substances," constructed in accordance with my improvements.
ог
a is the standard or upright, which is of ordinary construction. b is a carriage
fitted so as to slide freely in the vertical guides c at the front of the standard or
upright a, and in which is mounted the plunger d, to which the "former"
pressing plate e is attached. The driving shaft f is provided at the back of the
machine, and is mounted in suitable bearings g and hand geared into the crank
shaft i transmitting motion thereto by the pinion k and spur wheel 7.
Now in my improvements in order to impart the required motion to the
carriage b carrying the plunger d, I employ the oscillating beam m mounted in
suitable bearings n at the upper part of the standard or upright a, which is
coupled to the carriage b by means of the short connecting rod o. Through the
beam m the required reciprocating vertical motion is imparted to the plunger d;
the beam m deriving its oscillating movement from the herein before mentioned
crank shaft i through the connecting rod p.
When preferred the crank shaft i and also the driving shaft f may be placed at
right angles to the beam m instead of parallel with the same as shewn in the
Drawings.
The required motion for pushing forward the brick or other substance to be
pressed is also derived from the crank shaft i, through the bell crank lever q; and

page_text: the motion for lifting or forcing out the form after being pressed is derived
the cam or eccentric r, on the crank shaft i actuating the lever 8.
B
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
1° The combination of the oscillating beam m, crank shaft i and plunger d, and
parts connected therewith, arranged and operating substantially as herein set
forth.
2° The combination and application of the various parts forming my improve-
ments in machinery for pressing coal, peat, and similar substances, all arranged and
operating substantially as herein set forth.
WILLIAM JOHNSON.
