Improvements in Break Apparatus for Carriages, Waggons, and
other Vehicles:
I, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings in the
County of Middlesex, Patent Agent, do hereby declare the nature of this inven-
tion, (a communication from Jules des Georges, of 44 Place de la Republique,
Lyons, in the Republic of France,) to be as follows, reference being had to the
accompanying drawing and to the letters marked thereon:-
The invention has for its object improvements upon an invention for which
Letters Patent were granted to me dated September 30, 1889, No. 15357.
The break block consists, as shown in the drawing, of a wedge A sliding upon a
box B suspended from the under frame of the carriage by a link E.
When this break block is caused to approach the wheel by any suitable
mechanism acting upon the double ended lever F, the friction of the wheel draws
the wedge shaped break block downwards between the wheel and the box B, and
produces automatically an energetic break action. Formerly the lifting of the
break block was effected by one or several springs. The present invention consists
in the application of compressed air, or of other fluid under pressure, to the
working of this kind of break, and the accompanying drawing represents how this
application can be carried into effect.
The break block A slides upon the front of the box B, which it closes
hermetically; it is fixed to a piston P which moves in the cavity of said box,
which it fits exactly. Two tubes CD convey to the two ends of the box com-
pressed air or other fluid under pressure contained in a reservoir R fixed to the
under frame of the carriage or to other convenient part; these tubes are provided
with cocks or other distributing apparatus which enable the air or other fluid to be
conducted to one or other face of the piston P.
By conducting the air or other fluid, by means of the tube C, to the upper face
of the piston, the break block is caused to descend until it comes into contact with
the wheel, which then draws it along to produce the automatic pressing or break
action; the over-running of the break can be prevented, and the action of the
break can be modified at will, by introducing the compressed air or other fluid
below the piston by the tube D.
The air introduced below the piston thus replaces the spring, at, the time of
releasing the break, to lift the break block and hold it in position when the air or
other fluid contained above the piston has been liberated.
The break block can also be operated directly by a pedal or other mechanisın
acting by the connecting rod H upon the two ended lever F, which latter is
connected to the box B by the connecting rod G.
I would have it understood that the arrangement above described is given only
as an example for the purpose of explaining the mode of action of the fluid under
pressure upon the wedge shaped break block, and it may be varied as desired and
according to circumstances.
Dated this 2nd day of March 1892.

1, BENJAMIN JOSEPH BARNARD MILLS of 23 Southampton Buildings in the
County of Middlesex Patent Agent do hereby declare the nature of this invention
a communication to me from Jules des Georges of 44 Place de la Republique,
Lyons in the Republic of France and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement
reference being had to the accompanying drawing and to the figures and letters of
reference marked thereon :-
The invention has for its object improvements upon an invention for which
Letters Patent were granted to me dated September 30th 1889 No. 15357.
The break block consists as shown in the drawing of a wedge A., sliding upon
a box B suspended from the under frame of the carriage by a link E.
When this break block is caused to approach the wheel by any suitable
mechanism acting upon the double ended lever F the friction of the wheel draws
the wedge shaped break block downwards between the wheel and the box B, and
produces automatically an energetic break action. Formerly the lifting of the
break block was effected by one or several springs. The present invention consists
in the application of compressed air or of other fluid under pressure to the working
of this kind of break and the accompanying drawing represents how this application
can be carried into effect.
The break block A slides upon the front of the box B which it closes
hermetically, it is fixed to a piston P, which moves in the cavity of said box which
it fits exactly. Two tubes C, D, convey to the two ends of the box compressed
air or other fluid under pressure contained in a reservoir R, fixed to the under
frame of the carriage or to other convenient part, these tubes are provided with
cocks or other distributing apparatus which enable the air or other fluid to be
conducted to one or other face of the piston P.
By conducting the air or other fluid by means of the tube C to the upper face of
the piston, the break block is caused to descend until it comes into contact with the
wheel which then draws it along to produce the automatic pressing or break action,
the over running of the break can be prevented and the action of the break can be
modified at will by introducing the compressed air or other fluid below the piston
by the tube D.
The air introduced below the piston thus replaces the spring, at the time of
releasing the break, to lift the break block and hold it in position when the air or
other fluid contained above the piston has been liberated.
The break block can also be operated directly by a pedal or other mechanism
acting by the connecting rod H upon the two ended lever F which latter is
connected to the box B by the connecting rod G.
I would have it understood that the arrangement above described is given only
as an example for the purpose of explaining the mode of action of the fluid under
pressure upon the wedge shaped break block and it may be varied as desired and
according to circumstances.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
The employment of compressed air or of other fluid under pressure to actuate
the break block of my automatic break for the purpose of placing it in contact

page_text: with the wheel or of raising it at the moment of release or finally for the purpose.
of modifying its action by opposing more or less its draft or movement by
the wheel.
