PROVISIONAL SPECIFICATION left by Jolin Samuel Foretier at the Office
of the Commissioners of Patents, with his Petition, on the 3rd June
1854. A communication.
I, JOHN SAMUEL FORETIER, of Carlton Hill, in the County of Middlesex,
Gent", do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
RAILWAY BREAKS AND IN MACHINERY CONNECTED THEREWITH," (a communication,)
to be as follows:-
My Invention consists of certain machinery for working railway breaks, by
which every break in the train can be locked or unlocked simultaneously.
The machinery consists of a double set of rods extending the full length of
each carriage, and connected together at the ends by chains, to allow for the
increased distance between the carriages when the train is starting or ascending
an incline. These rods are mounted in suitable sockets or bearings, and the
two rods of each carriage are connected together, either by a connecting bar or
beam, so that when one advances the other must recede, and vice versa; or in
place of the beam, the rods are geared to a pinion, as hereafter mentioned. To
carriages not having a break the rods and beam only are required. To carriages
with breaks, I attach, in addition to the rods, the following gearing, that is to
say On the shaft of the break rod I fit a pinion, so as to rise and fall
by a lever, and to throw in and out of gear with a driving wheel, hereafter
mentioned, mounted on a shaft between the parallel rods. In these rods I

page_text: form a number of indentations or teeth to constitute a rack, one in each rod.
In these racks a rack wheel works; this rack wheel is mounted on the shaft
between the parallel rods. Above the rack wheel and on the same shaft I
mount the driving wheel, which gears with the pinion on the handle shaft of
the break when the said pinion is let down by the lever; by this means any
number of breaks can be connected, and the turning or locking of any one
break will also turn or lock the rest, or as many as may be in gear with the
connecting rods. To the tender I attach similar parallel rods and machinery,
and in addition thereto either a double fan or wheel on the driving wheel
shaft of the break machine, enclosed in a cylinder, with the escape pipe
opening into the water in the tender. This fan or wheel is made so as to be
turned either way by the steam. Or in lieu of the said fan I attach a small spur
wheel to the axle of the fore wheel of the tender; and to a vertical shaft attach
another wheel, gearing with the latter, but so as to throw in and out of gear
by a lever, and by this shaft the driving wheel of the machine on the tender
may be driven; so that when it should be necessary to stop the train, it could
be done either by having the fan wheel and by turning on the steam, or by
the means last mentioned, by throwing the wheel on the vertical shaft into
gear with the spur wheel on the axle of the wheel of the tender. The
respective breaks would then be all instantly locked, and could be also instan-
taneously unlocked by reversing the motion of the rods. When the machinery
is not in gear with the breaks they can be locked and unlocked, as at present,
by hand.
