Improvements in the Driving Arrangement of Combined
Brickmaking and Pressing Machines.
1, WILLIAM JOHNSON Engineer Castleton Foundry, Leeds, in the County
of York 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 :-
My invention has special reference to improvements in the driving gear of
combined brickmaking and pressing machines. The object of my invention is to
reduce the number of wheels and shafts and also to re luce the friction, and wear
and tear due to the use of a large number of wheels.
In order to more fully describe the improvements in my invention, reference is
made to the accompanying drawings.
Fig. 1. is a plan of the back end of the machine shewing the original mode of
driving the said machine. Fig. 2. is a plan of the same end of the machine
hewing the improvements embodied in my invention for driving the said machine.
The original machine was driven by the fast and loose pulleys (A' A¹) Fig. 1.
fixed on the shaft (B) and suitably mounted in the bearings (C¹). On the end of
the pulley shaft and nearest the main frame a pinion (E) is keyed, which gears at
the right hand side with the spur wheel (F) keyed to the shaft (G) parallel to the
pulley shaft. To this shaft two pinions are keyed, one the bevel pinion (H) which
is geared to the bevel wheel (L'), keyed on the end of the pug shaft Dappertaining
to the barrel of the brick machine. The other pinion (J) is geared to the spur
wheel (K) which also forms a crank wheel operating the cylinder containing the
brick moulds. The above forms the driving arrangement for the brick making part
of the machine.
The pressing part of the machine is driven from the left hand side of the
pinion (E) on the pulley shaft, which gears to the spur wheel (M') and mitre
wheel (N) cast together and running loose on the shaft (O). The mitre wheel (N¹)
gears to the mitre wheel (Q1) keyed on the shaft (P) at right angles to the pulley
shaft and used for driving the pressing part of the machine.
I desire to state here that since the original machine was first made I have
somewhat improved the driving of the machine by removing altogether the spur
wheel (M), and have cast the bevel wheel (N) on to the pinion (E) and carried
the bevel wheel (Q) to a suitable position for gearing into the wheel (N). This
improvement enables the said wheel (M) along with the pedestals, shaft and
brackets to be dispensed with altogether, but the pinion (E) and the wheel (FI)
along with the shaft (B) and the bearings (C) still remain and these as
hereinafter described are also removed by the improvements in my invention
which are as follows.
(A', A¹) Fig. 2. are the two driving pulleys fast and loose keyed on to the
shaft (G). (N', H & J) are three pinions keyed on to the same shaft. The bevel
pinion (N) engages the pinion (2) driving the pressing part of the machine.
The bevel pinion (H') engages the bevel wheel (L') driving the pug shatt (D) and
the spur pinion (J) engages the spur wheel (K) which operates the cylinder
containing the brick moulds. It will be seen that by placing the pulleys direct on
the shaft (G') and fixing all the driving pinions also on the same shaft that the
whole machine can be driven from one main shaft (G¹).
In making this improvement in the driving, by reducing the number of wheels

page_text: and shafts I make the pulleys and gearing of a suitable size and pitch in order to
keep the gain in power or purchase of the wheels the same as before
In the original machine the centie line of the shaft (N) is on the same level as
the centre line of the shaft (D), but in ny invention I lower the centre line of
shaft (N) sufficiently to enable the said shaft to pass under the shaft (D) and be
supported in a bearing on the opposite frame or other suitable place beyond the
shaft (D). By passing the said shaft either over or under the shaft (D) a much
longer shaft can be used, which gives greater stability to the working of the
wheel (K) which is keyed on to this shafi.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
First. In a combined brickmaking and pressing machine a cross shaft (G)
Fig. 2, mounted with fast and louse pulleys and having fixed thereto also the
pinions (N, H' & J) for driving the pressing and brickmaking parts of the
machine, substantially as herein described and illustrated.
Second. In a combined brickmaking and pressing machine the arrangement of
pulleys and wheels with their respective driving and driven shafts, substantially as
herein described and illustrated.
Third. In a combined brickmaking and pressing machine the shaft (N) passing
either under or over the shaft (D) to any suitable support or bearing beyond,
substantially as herein described and illustrated.
Dated this the 31st of January 1896.
