page_text: LETTERS PATENT to Thomas Young Hall, of the Town and County of
Newcastle-upon-Tyne, Mining Engineer and Coal Owner, and Joseph
Stockley, of the same Place, Engineer, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR COMMUNICATING SIGNALS APPLICABLE TO RAILWAY TRAINS
AND VEHICLES AN LAND AND TO VESELO ON WATED"
PROVISIONAL SPECIFICATION left by the said Thomas Young Hall
and Joseph Stockley at the Office of the Commissioners of Patents, with
their Petition, on the 30th May 1861.
We, THOMAS YOUNG HALL, of the Town and County of Newcastle-upon-
Tyne, Mining Engineer and Coal Owner, and JOSEPH STOCKLEY, of the same
Place, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR COMMUNICATING SIGNALS APPLICABLE TO RAIL-
WAY TRAINS AND VEHICLES ON LAND, AND TO VESSELS ON WATER," to be as
follows:-
Our Invention has for its object the employment of compressed air of
sufficient density to blow whistles or alarums, and produce considerable sound
therefrom so as to be capable of conveying, by means of a pre-arranged code of
signals, any desired intelligence, which may be distinctly heard at a distanco
from the place whence the sound is emitted. For this purpose the whistles or
alarums are to be placed in, or on, or connected with receivers or domes con-
taining the compressed air for sounding the same, and placed in any convenient
place in a railway van or carriage, or other vehicle, or on board of a vessel.
The air is to be worked when required by a force pump set in motion by an
eccentric or crank on or connected to the axle or axles of the railway van or

TO ALL TO WHOM THESE PRESENTS SHALL COME, WC, THOMAS
YOUNG HALL, of the Town and County of Newcastle-upon-Tyne, Mining
Engineer and Coal Owner, and JOSEPH STOCKLEY, of the same Place, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of May, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Thomas Young Hall and Joseph Stockley, Hor special license that we, the
said Thomas Young Hall and Joseph Stockley, our executors, adminis-
trators, and assigns, or such others as we, the said Thomas Young Hall and
Joseph Stockley, our exccutors, 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 "IMPROVE-
MENTS IN APPARATUS FOR COMMUNICATING SIGNALS APPLICABLE TO RAILWAY
TRAINS AND VEHICLES ON LAND, AND TO VESSELS ON WATER," upon the
condition (amongst others) that we, the said Thomas Young Hall and
Joseph Stockley, by an instrument in writing under our hands and
seals, or under the hand and seal of one of us, 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 we, the said Thomas Young Hall and Joseph
Stockley, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the Drawings
hereunto aunexed, and to the letters and figures marked thereon (that is
to say):

page_text: Our Invention of "Improvements in Apparatus for Communicating Signals
applicable to Railway Trains and Vebicles on Land, and to Vessels on Water,"
has for its object the employment of compressed air of sufficient density-to blow
whistles or alarums, and produce considerable sound therefrom so as to be
capable of conveying, by means of a pre-arranged code of signals, any desired
intelligence, which may be distinctly heard at a distance from the place
whence the sound is emitted. For this purpose the whistles or alarums are to
be placed in, or on, or to be connected with receivers or domes containing the
compressed air for sounding the same, and placed in any convenient place in
a railway van or carriage, or other vehicle, or on board of a vessel. The air is
to be worked when required by a force pump set in motion by an excentric. or
crank on or connected to the axle or axles of the railway van or carriage or
other vehicle, or by hand, water, or wind, suitable mechanism for acting on the
compressed air being provided.
:
Having thus stated the nature of the said Invention, we will proceed to
describe more particularly in what manner the same is to be performed by
reference to the accompanying Drawings, in which are represented two modes
of applying our Invention.
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 shew an arrangement by which the force pump is worked by
an excentric. Fig. 1 is a side view and Fig. 2 an end view of the mechanism;
Fig. 3 represents a modication by which a longer stroke in the cylinder can be
obtained than by the former arrangement.
A is the axle of the carriage or van to which the apparatus is applied; Bis
a friction cone keyed upon the same; C is the excentric which has cast in
one piece and with it the hollow cono D, which fits the cone B. The
excentric is suspended by a strap E, having projecting pins F on each side fitting
the eyes of the hangers G, which are keyed on to a weigh bar H. There is
also a lever I keyed on to the weigh bar, which has connected to it the rod K
for the purpose of putting the excentric into and out of gear. On raising the
handle of tho rod K, the friction cone B is brought into action, and the
excentric C is carried round in the suspending strap, and is thereby made to
work the force pump.
It will be seen that the excentric is clear of the shaft, so that when the cone B
is disengaged there is no wear and tear of the parts, the shaft revolving freely
in the space J. The force pump is an ordinary air pump of any convenient
size, with air holes in the cylinder as shewn, and the dome may be placed inside
or on the top of the van or elsewhere, or a pipe of sufficient dimensions

page_text: standing upright in the van, with a whistle at the top, will answer the
purpose.
In the arrangement shewn at Fig. 3, a longer stroke in the cylinder than in
that just described can be obtained. On the axle A is keyed a wedge and
groove friction pinion B, and above it and gearing into it is a wheel C, of the
same description, and which may be made to reduce the speed and regulate the
action of the pump if required. This wheel is keyed on to the axle shaft D,
which may have one or more cranks to work at the same time more pumps
than one, if thought necessary. The connecting rod E is made to work the
piston F G is a check valve. In this arrangement the putting of the
apparatus in and out of gear is effected by means of a handle H connected
to the cam lever I, by which the brasses K are pressed down, they being
free to slide up and down to a small extent in the bearing; M, M, are
india-rubber washers to admit of such motion. Various kinds of whistles or
alarums may be applied to or connected with the dome, which it may be
preferable in some cases to fix horizontally instead of vertically, as shewn in
Fig. 3; also the cylinders of the pumps may be varied in dimensions, and
the mode of working the pumps may likewise be varied.
Having thus described the nature of the said Invention, and in what manner
the same is to be performed, we do hereby declare that what we claim as of
our Invention is, the adaptation and application to railway vans, carriages, or
other vehicles on land, and to vessels on water, of apparatus by means of which
compressed air is caused to produce sound signals by the action of a force
pump connected, when required, with the moving parts, as herein-before
:described, or otherwise worked:*--
In witness whereof, we, the said Thomas Young Hall and Joseph
Stockley, have hereunto set our hands and seals, the Twenty-eighth
day of November, in the year of our Lord One thousand eight hundred
and sixty-one
