IMPROVE- MENTS IN CONTINUOUS RAILWAY BRAKES to be as follows:
Year: 1884

page_text: I, GEORGE JACKSON of Bottoms, Walsden n Todmorden in the County of
Lancaster, Engineer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN CONTINUOUS RAILWAY BRAKES to be as follows:-
"
My invention relates to improvements in continuous railway brakes and has for
its object to produce a brake which will act on every carriage of a train with more
certainty, simultaneously and instantaneously or gradually with more effect and
with less wear and tear or damage to the carriages.
My improvements consist in applying friction blocks direct onto the rails
instead of onto the tyres of the wheels as heretofore has been the case. To this
end I arrange two or more friction blocks of iron or other material, being faced
with wood, on each side of the framing of a carriage either in front of the wheels
or between them. These friction blocks are arranged to be slid up and down in
a casing in a vertical or diagonal direction open at the bottom or frame, fixed to
the sides of the frame of the carriage.
The said friction blocks are provided with slots in which a cam or eccentric
works, keyed onto each end of a cross shaft mounted in suitable bearings fixed to
the frame underneath the carriage. These cross shafts are compounded by means
of levers or any other suitable means to a longitudinal shaft mounted also
underneath the frame of the carriage in suitable bearings.
The ends of the longitudinal shafts of the different carriages are suitably coupled
together and caused to be rotated from a vertical shaft, operated by the guard in
the van by means of a worm and wheel fixed thereto.
It will thus be understood that the guard in the van is enabled to apply the
friction blocks of all the carriages simultaneously onto the rails by means of the
said vertical shaft which causes the cams or eccentrics to rotate and drop the
blocks and brake or retard the carriages by bringing the wheels out of contact with
the rails.
In case a train of carriages were to become disconnected by any means whatever,
the friction blocks will work self-actingly and independently of the guard, thus
stopping at once both parts of the disconnected train.

Bosshardt & Grant.

I, GEORGE JACKSON, of Bottoms Walsden near Todmorden in the County of
Lancaster Engineer, do herby declare the nature of my invention for "IMPROVE-
MENTS IN CONTINUOUS RAILWAY BRAKES and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements in continuous railway brakes and has for
its object to produce a brake which will act on every carriage of a train, with more
certainty, simultaneously or gradually with more effect and with less wear and
tear or damage to the carriages.
And in order that my invention may be better understood I have caused to
be appended hereunto one sheet of drawings. marked with letters of reference
indicating like parts in the various figures.
Fig 1 is a side elevation.
Fig 2 is a longitudinal section and Fig 3 is a cross section of a carriage showing
the same provided with brakes according to my invention.
My improvements consist in applying friction blocks direct onto the rails
instead of onto the tyres of the wheels as heretofore has been the case. To this
end I arrange two or more friction blocks a of iron or other material on each side
of the framing b of a carriage either in front of the wheels or between them.
These friction blocks are provided with a flange b' and may be faced with wood
or any other suitable material and are arranged to be slid up and down in a casing c,
preferably in a vertical direction, open at the bottom, or in a frame fixed to the sides
of the framing b of the carriage.
The said friction blocks are provided with slots d in which a cam or eccentric e
works, keyed onto each end of a cross shaft f mounted in suitable bearings y fixed
to the framing b underneath the carriage A. The cross shafts ƒ are compounded
by means of levers, or geared up to a longitudinal shaft h mounted also underneath
the frame in suitable bearings i by the worm j and worm wheel k.
The ends of the longitudinal shafts h of the different carriages are coupled
together by means of a he and she coupling and m or other suitable means &
caused to be rotated from a vertical shaft o operated by the guard in the van, by
means of a worm and wheel or bevel wheel gearing p hand wheel q & bevel wheel r
fixed thereto.
In order to limit the motion of the friction blocks a I may provide the same at
the top and bottom with adjustable projection pieces which are arranged to come
into contact with other projections formed on the casing or frame of the blocks.
To facilitate the coupling of the shafts h, I may arrange a wheel catch and lever
by means of which the coupling will always remain and can be brought into the
proper position and coupled instaneously with the corresponding part.
It will thus be understood that the guard in the van is enabled to apply the
friction blocks of all the carriages simultaneously onto the rails by means of the
said vertical shaft or the longitudinal shaft may be coupled up and worked from
the engine, which causes the cams or eccentrics to rotate and drop the blocks &
brake or retard the carriages by bringing the wheel out of contact with the rails,

page_text: ever,
When the longitudinal shaft h is connected to the vertical shaft o by means of
levers, and if a train or carriages were to become disconnected by any means what-
the friction blocks on account of their own weight will drop onto the rails
thus working self-actingly and independently of the guard, and stopping at once
both parts of the disconnected train. This invention is applicable on all kinds of
railroads.
Having now 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
1st Providing railroad carriages with a brake the friction blocks of which are
applied onto the rails and actuated by the guard or driver of the carriage or train
either by steam or hand power as set forth.
2nd The friction blocks a sliding in a frame or casing c fixed to the framing b
of the carriage actuated by cams or eccentrics e fixed on the cross shafts f which
latter receives rotary motion from a longitudinal shaft h actuated by suitable
means as set forth.
