IMPROVED BRAKE APPARATUS FOR RAILWAY AND TRAMWAY VEHICLES
Year: 1884

page_text: I WILLIAM CORTEEN of 41, North Church Street Sheffield in the County of
York Carriage Maker, do hereby declare the nature of my Invention for
"IMPROVED BRAKE APPARATUS FOR RAILWAY AND TRAMWAY VEHICLES" to be as
follows:-
The chief object of my Invention is, on the stopping and resistance of the
engine, and pressing back of the buffers, to utilize the momentum of the carriages
behind.
To effect this, I attach a rod to each buffer, and by a series of connecting rods,
worked mostly by fulcrum joints, the brake blocks are applied in a firm manner
to the wheels, and, if desired, the grip can be to both the back and front of the
same.
The suspending stays, to which the blocks are attached, are so constructed as to
grip the tyres gradually, so as to decrease the sudden jerks and vibration which
occur when stiff block applications are used.
Spring actions (usually in lieu of those at present employed) are fitted to the
buflers, and carry the same forward, so as to liberate where required the brake
application, and for the purpose of shunting, or where otherwise necessary, the
operation of the brake may be suspended by the employment of a simple check
action.
By a contrivance fitted in the brake van, the person in charge, can by his own
power, assist the power gained from the buffers, by working in conjunction with
same (or he may employ his own power without reference to the buffers) and the
check action is also regulated by him.
The accompanying Drawings illustrate the application of my Invention.
Figure 1 shews the parts from a top view when the brake is off or suspended.
Figure 2 is a side elevation of same.
Like letters of reference where such letters appear indicate corresponding parts
in the Drawings.
As the stopping of the engine and pressure forward of the carriages, press in the
buffer, this movement of the buffer is then employed as the motive power for
working the brake.
To effect this, the rod A attached to the buffer, pushes back the rod B upon the
brake block C-The buffer rod runs through the cross bar D, and has a nut

page_text: thereon at the point E-F is an india-rubber or other elastic block interposed
between the nut and the top part of the suspending stay or arm G, kept together
by the chain as shewn, and as the buffer rod moves, the nut and india-rubber or
other block move with it, away from the cross bar D, and push back the stay or
arin G, which latter thereby works the two brake blocks H and I.
G¹ is a stationary joint, and on the pressing back of the upper arm, the lower
arm G' is pressed towards the wheel, and so puts on the brake H-I is pulled on
direct by the arm J, K. and L being stationary joints-At the other end of the
carringe, the rod P pushes back and puts on the brake block M, and the brake
blocks N and O are worked from the stationary joints Q and R as shewn.
The lower part of the suspending stay or arm G, is, so as to avoid jerks,
constructed as shewn at G2 and works as a spring throughout-G³ is a short spiral
spring which is fastened to the suspending arm by a nut as shewn, and such
spring being pressed down with the arm puts on the brake by a gradual pressure
The other blocks are worked correspondingly, in all cases being applied, as shown,
to both the back and front of the wheel.
The spring S attached to the buffer pushes out and liberates the buffer where
required.
-
The check action to be employed where necessary, is worked by hand from the
guard's van by the wheel rack lever T―This lever operates upon the rods U which
raise the arm-V-and-so-prevent-the buffers being worked, such arm being lowered
by the reverse action of the lever-A hook is also fixed at the end of the rod-U-
and attached to_a_corresponding hook on the next carriage, working the reverse
way, whereby the check action applies throughout..
To assist the power gained from the buffers, the cross bar D is pulled towards
the centre of the carriage thereby drawing with it the suspending stay or arm G,
-with-the-block and nut F and E attached to same-To effect this, the screw hand
lever W, worked from the guard's van, operates on the swivel joint-X-by-means_of_
the rod X, and such swivel joint X¹ is moved so as to pull forward by the rod Z
the cross bar D-The corresponding cross bar Y is also thereby pulled forward as
shewn.

page_text: I WILLIAM CORTEEN of 41, North Church Street Sheffield in the County of
York Carriage Maker do hereby declare the nature of my Invention for
"TMPROVED BRAKE APPARATUS FOR RAILWAY AND TRAMWAY VEHICLES" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The chief object of my Invention is, on the stopping and resistance of the
engine, and pressing back of the buffers, to utilize the momentum of the carriages
behind.
To effect this I attach a rod to each buffer and by a series of connecting rods
worked mostly by fulcrum joints, the brake blocks are applied in a firm manner
to the wheels, and if desired, the grip can bo to both the back and front of the
same.
The suspending stays, to which the blocks are attached, are so constructed as to
grip the tyres gradually, so as to decrease the sudden jerks and vibration which
occur when stiff block applications are used.
Spring actions (usually in lieu of those at present employed) are fitted to the
buffers and carry the same forward so as to liberate where required, the brake
application, and for the purpose of shunting or where otherwise necessary, the
operation of the brake may be suspended by the employment of a simple check
action.
By a contrivance fitted in the brake van, the person in charge can by his own
power assist the power gained from the buffers, by working in conjunction with
same, (or he may employ his own power without reference to the buffers,) and the
check action is also regulated by him.
The Drawings accompanying my Provisional Specification illustrate the application
of my Invention.
Figure 1 shows the parts from a top view when the brake is off or suspended.
Figure 2 is a side elevation of same.
Like letters of reference where such letters appear indicate corresponding parts
in the Drawings.
As the stopping of the engine and pressure forward of the carriages press in the
buffer this movement of the buffer is then employed as the motive power for
working the brake.
To effect this the rod A attached to the buffer pushes back the rod B upon the
brake block C-The buffer rod runs through the cross bar D and has a nut thereon
at the point E-F is an india-rubber or other elastic block interposed between the
nut and the top part of the suspending stay or arm G, kept together by the chain
as shewn, and as the buffer rod moves, the nut and india-rubber or other block
move with it away from the cross bar D, and push back the stay or arm G, which
latter thereby works the two brake blocks H and I.
G is a stationary joint, and on the pressing back of the upper arm, the lower
arm G is pressed towards the wheel, and so puts on the brake H-I is pulled on
direct by the arm J, K and L being stationary joints-At the other end of the
carriage, the rod P pushes back and puts on the brake block M, and the brake
blocks N and O are worked from the stationary joints Q and R as shewo.
The lower part of the suspending stay or arm G is, so as to avoid jerks,
constructed as shewn at G³ and works as a spring throughout G³ is a short spiral
spring which is fastened to the suspending arm by a nut as shewn, and such spring
being pressed down with the arm puts on the brake by a gradual pressure-The

other blocks are worked correspondingly, in all cases being applied as shewn to
both the back and front of the wheel.
The spring S attached to the buffer pushes out and liberates the buffer where
required.
The check action to be employed where necessary, is worked by hand from the 5
guard's van by the wheel rack lever T. This lever operates upon the rods U,
which raise the arm V and so prevent the buffers being worked, such arm bing
lowered by the reverse action of the lever. A hook is also fixed at the end of the
rod U and attached to a corresponding hook on the next carriage working the
reverse way, whereby the check netion applies throughout.

To assist the power gained from the buffers the cross bar D is pulled towards
the centre of the carriage thereby drawing with it the suspending stay or arm G
with the block and nut F and E attached to same-To effect this, the screw
hand lever W worked from the guard's van, operates on the swivel joint X' by
means of the rod X and such swivel joint X' is moved so as to pull forward by the 1
rod Z the cross bar D. The corresponding cross bar Y is also-thereby-pulled.
forward as shewn.
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:
Eirst. The above described improved railway brake apparatus, whereby on the
stopping of the engine, the momentum of the carriages, is, by means of a rod
from the buffer_and_n_series_of_connecting rods, utilized, and an increased grip
obtained by land lever where necessary.
Second. The avoidance of jerks by means of the suspending arms or stays, 2
securing a gradual pressure on the wheels, and securing such pressure to both the
back and front of the wheels, if required.
Third. The suspension of the application by a check action, where for-shunting
or otherwise necessary.
Fourth. The general improvements in the application of brakes-to-railway-3
carriages, and tramcars as herein and in the Drawings substantially described and
set forth.
