Sealed the 1st August 1864, and dated the 5th February 1864.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 5th February 1864.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention'
for "IMPROVEMENTS IN BREAKS FOR RAILWAY AND OTHER WHEELS," to be as
follows:-
This improved break is applicable to the axles or spindles of locomotives,
wagons, steam and hydraulic engines, to fly wheels and driving pulleys, as
well as to the wheels of carriages, that is to say, that in every vehicle, appa-
ratus, or appliance in which an axle or spindle turns this break is applied to
the axle or spindle, and that in every vehicle, apparatus, or appliance in
which the spindle is stationary the break is applied to the wheel, pulley, or
other moving part.

page_text: I proceed to describe, by the aid of the accompanying Drawings, the
manner in which this approved break is applied to a railway wagon.
Figure 1 is a side view of part of a wagon X. On the axle A I fit a
toothed disc B, into one or other of the recesses of which a block C, acted
upon by a strong coiled spring D, takes. The disc B is fitted on the axle, as
shown in Figures 2 and 3, in such manner that it revolves with the wheels,
but as soon as the block C engages, by the expansion of the spring D, in one
of the recesses in the disc the revolution of the disc, and consequently of the
wheels, ceases. (If the break is fitted to an ordinary carriage, the axle of which
is fixed, the disc B is not attached to the axle but to the nave of one of the
wheels). The block C slides in a strong guide a, Figure 4, and is furnished
at top with a chain or cord 6 attached to bar E; this bar may be placed in
any desired position, and may be actuated by the hand or foot by means of a
chain or cord guided by pulleys. The bar E slides in a guide d, in the interior
of which a catch e with a projecting button g is fitted. When it is required
to raise the block C, to disengage it from the toothed disc the, bar E is raised
by means of the chain h, one end of which is secured at h¹, while the other
end his free; this raising of the block engages a projection of the bar E in
the catch e which is acted on by a spring 1; at the required moment the
attendant, by means of a cord, chain, or lever, releases the bar E from the
catch e, the bar is thus suddenly submitted to the action of the spring D and
the block C engages in one of the recesses of the disc B and stops the revo-
lution of the axle A. Below the wagon a sliding bolt F (shown detached in
Figure 6) is fitted, it is connected to the chain 6 by a chain or cord m. This
bolt is arranged in such manner that when the block C descends to take into
the disc B the bolt engages into a hole in the block, and thus prevents the
block rising again, which it would do if the spring D were to break. The
connection of the bolt F and block C by the chain m renders their action
simultaneous. The break may be made automatic by means of steam made
to act on a wheel in one direction to disengage the bar, and in the other
direction to engage it. In locomotives the bar would be furnished with a
slide arranged to act as a steam cock, and with a second slide which will open
the cock for the escape steam to assist in stopping the train. On railways the
break may be fitted to each wheel of the locomotive and to the last carriage,
with communication, if desired, between the bars by electricity.

by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 5th August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of February, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Richard Archibald Brooman, Her special licence that I, the
said Richard Archibald Brooman, my executors, administrators, and assigns,
or such others as I, the said Richard Archibald Brooman, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for " IMPROVEMENTS IN BREAKS FOR
RAILWAY AND OTHER WHEELS," (communicated to me from abroad by Alfred
Charles Fleury, of Paris, France,) upon the condition (amongst others) that
I, the said Richard Archibald Brooman, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof, reference being had to the Drawings hereunto
annexed, that is to say :-
This improved break is applicable to the axles or spindles of locomotives,
wagons, steam and hydraulic engines, to fly wheels, and driving pulleys, as
well as to the wheels of carriages; that is to say, that in every vehicle, appa-
ratus, or appliance in which an axle or spindle turns, this break is applied to
the axle or spindle, and that in every vehicle, apparatus, or appliance in which

page_text: the spindle is stationary the break is applied to the wheel, pulley, or other
moving part.
I proceed to describe, by the aid of the accompanying Drawings, the
manner in which this improved break is applied to a railway wagon.
Figure 1 is a side view of part of a wagon X. On the axle A I fit a
toothed disc B, into one or other of the recesses of which a block C, acted upon
by a strong coiled spring D, takes. The disc B is fitted on the axle, as shewn
in Figures 2 and 3, in such manner that it revolves with the wheels; but as
soon as the block C engages by the expansion of the spring D in one of the
recesses in the disc, the revolution of the disc, and consequently of the wheels,
ceases. (If the breab is fitted to an ordinary carriage, the axle of which is
fixed, the disc B is not attached to the axle but to the nave of one of the
wheels). The block C slides in a strong guide a, Figure 4, and is furnished
at top with a chain or cord 6 attached to a bar E. This bar may be placed
in any desired position, and may be actuated by the hand or foot by means of
a chain or cord guided by pulleys. The bar E slides in a guide d, in the
interior of which a catch e with a projecting button 9 is fitted (see Figure 5).
When it is required to raise the block C to disengage it from the toothed
disc, the bar E is raised by means of the chain h, one end of which is secured
at h', while the other end h¹¹ is free. This raising of the block engages a
projection of the bar E in the catch e, which is acted on by a spring 1; at the
required moment the attendant, by means of a cord, chain, or lever, releases
the bar E from the catch e; the bar is thus suddenly submitted to the action
of the spring D, and the block C engages in one of the recesses of the disc B
and stops the revolution of the axle A. Below the wagon a sliding bolt F
(shewn detached in Figure 6) is fitted; it is connected to the chain 6 by a
chain or cord m. This bolt is arranged in such manner that when the
block C descends to take into the disc B, the bolt engages into a hole in the
block, and thus prevents the block rising again, which it would do if the spring
D were to break. The connection of the bolt F and block C by the chain m
renders their action simultaneous. The break may be made automatic by
means of steam made to act on a wheel in one direction to disengage.the
bar, and in the other direction to engage it. In locomotives the bar would
be furnished with a slide arranged to act as a steam-cock, and with a second
slide which will open the cock for the escape steam to assist in stopping the
train. On railways the break may be fitted to each wheel of the locomotive;
and to the last carriage with. communication, if desired, between the bars by
electricity.
And having now described the nature of the said Invention, and in what

page_text: manner the same is to be performed, I declare that I claim, constructing
breaks for railway and other wheels in which the break power is applied
substantially in manner herein-before described, with reference to the accom-
panying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Fifth day of August, One thousand
eight hundred and sixty-four.
R. A. BROOMAN. (L.B.)
