IMPROVEMENTS IN BRAKES, AND IN THE MANNER OF APPLYING THE SAME
Year: 1885

page_text: I EDWARD FULLER MAITLAND, of No 12 Grafton Street, Bond Street, in the
County of Middlesex, Gentleman, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN BRAKES, AND IN THE MANNER OF APPLYING
THE SAME" to be as follows:-
This Invention relates to improvements in brakes for railway carriages or
wagons, and consists in the use of apparatus for automatically applying and
removing the same from the wheels according as it may be necessary to stop the
train or carriage or set it in motion.
The slippers of the brake are attached to levers hinged to the side frames or
timbers of the carriage, the hinge or fulcrum being near to the slipper.
The brake is applied by means of a spring similar to an ordinary carriage spring
and is removed by means of an automatic arrangement consisting of a cross shaft
on each end of which is mounted a wheel carrying two pius in such manner that as
the wheels revolve in either direction, one of the two pins will depress the brake
lever on each side of the carriage and remove the slipper.
The wheels or shaft carrying the same are connected by means of tooth wheel,
rack or other mechanical equivalent with the buffers and coupling bars or with the
framework to which the same are connected. Instead of the usual spiral springs
employed in connection with the buffers and coupling bars I propose to employ
springs similar to the ordinary carriage springs fixed underneath the carriage and
acting on a cross bar or frame to which the buffers and coupling bar may be
attached.

Improvements in Brakes and in the Manner of Applying
the same.
I, EDWARD FULLER MAITLAND of No 12 Grafton Street, Bond Street in the
county of Middlesex, Gentleman do hereby declare the nature of my invention
for IMPROVEMENTS IN BRAKES AND IN THE MANNER OF APPLYING THE SAME, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :--
This invention relates to improvements in brakes for railway carriages or
wagous and consists in the use of apparatus for automatically applying the same
or removing the same from the wheels according as-it may be necessary to stop the
train or carriage or to set it in motion.
The slippers of the brake are attached to levers a hinged to the side frames or
timbers of the carriage, the hinge or fulcrum b being near to the slipper, and may
be made capable of moving in a horizontal direction by means of a slit in the lever.
The Brake is applied by means of a spring c similar to an ordinary carriage
spring to which the extremities of the said levers are attached; or else by means
of a screw a situated in the centre of the said spring; and is removed by means of
an automatic arrangement consisting of a cross shaft e at each end of which is
mounted a wheel or peice f, carrying two pins m, n, in such a manner that as the
wheels or peices revolve in either direction one of the two pins will depress the
brake lever on each side of the carriage or wagon and remove the slipper; or else
by means of the said screw d. The wheels or peices carrying the pins are connected
by means of a slit g therein or other mechanical equivalent with the framework h
to which both the buffers and coupling bar are connected. Instead of the usual
spiral springs employed in connection with the buffers and coupling bar, I propose
to employ springs similar to the ordinary carriage springs, fixed underneath the
carriage and acting on a crossbar or frame to which the buffers and coupling bar
may be attached.
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:
L
1. The automatie application of the brake by means of a carriage spring fitted at
the end of the carriage or wagon, the said spring serving the three functions of
buffer, coupling bar and brake spring and connected with the extremities of two
levers as herein before described.
2. The manual application or removal of the brake by means of a screw situated
in the centre of the said spring substantially as herein before described.

page_text: 3. The mechanical method for removing the brake automatically from the wheels
through pressure on the said levers exerted by two pins mounted on a wheel or
peice which being connected by means of a slit or other mechanical device in the
same to the framework to which both the buffers and drawhook are attached is
caused to revolve in alternate directions according as there is pressure on the
buffers or traction on the drawhook as hereinbefore described.
