Year: 1869

page_text: LETTERS PATENT to Thomas Evans Lundy and John Lingard Dunham,
both of No. 166, City Road, in the County of Middlesex, Engineers,
for the Invention of "NEW OR IMPROVED MEANS OF COMMUNICATION
BETWEEN PASSENGERS IN CABS, PRIVATE CARRIAGES, OMNIBUSES, TRAMROAD
CARS, AND OTHER SUCH LIKE VEHICLES, AND THE DRIVERS OR CONDUCTORS
THEREOF."
Sealed the 17th May 1870, and dated the 19th November 1869.
PROVISIONAL SPECIFICATION left by the said Thomas Evans Lundy
and John Lingard Dunham at the Office of the Commissioners of
Patents, with their Petition, on the 19th November 1869.
We, THOMAS EVANS LUNDY and JOHN LINGARD DUNHAM, both of
No. 166, City Road, in the County of Middlesex, Engineers, do hereby
declare the nature of the said Invention for "NEW OR IMPROVED MEANS OF
COMMUNICATION BETWEEN PASSENGERS IN CABS, PRIVATE CARRIAGES, OMNIBUSES,
TRAMROAD CARS, AND OTHER SUCH LIKE VEHICLES, AND THE DRIVERS OR CONDUCTORS
THEREOF," to be as follows:-
This Invention consists, firstly, in the use of signal boards, discs, or
plates of any convenient form without. or outside the vehicle, which

page_text: "
signal boards, discs, or plates are operated by means of levers or rods
within the vehicle. Any number of signal boards, discs, or plates may
be used, and and where more than one is employed they may be coloured
or lettered, so that each separate board, disc, or plate shall signify or
convey to the driver or conductor of the vehicle a different signal or
command, such as "stop," right," "left," "slow," or signals or
commands of other import if necessary. The part of the vehicle at
which the external signals are fixed will be determined by the particular
kind of vehicle in which they are used, for example, in cabs and ordinary
road carriages in which the driver sits in front the signals may be
exhibited on, or above, or in front of the dashboard, while in omnibuses
or tramroad carriages they may be exhibited to the conductor at the rear
thereof, who may then communicate by like means to the driver. Or in
this case the connections may be so arranged with a double set of signals
as to convey the like commands simultaneously to both conductor and
driver. It is proposed in some instances to fit the signal boards, discs,
or plates, or the rods or levers carrying the same with a tongue, which
shall by passing over ratchet teeth cause a rattling noise to call the
attention of the driver or conductor to the fact that he is being signalled
to. Or the signal boards, discs, or plates may carry the ratchet teeth,
and the tongue may be fixed.
This Invention consists, secondly, in the use of bells, or gongs for
the purpose of signalling cither in connection with the herein-before
described, arrangements or separately. This part of the Invention where
used without the visible signals relates principally to cabs, private
carriages, coaches, and such like vehicles, and a bell or gong placed by
preference externally is connected by means of rods, levers, or wires to a
lever or other pull within the vehicle, and by arrangement any given
number of strokes upon the bell or gong will convey signals or commands
of different import to the driver. In some vehicles it may be found more
.convenient and we propose to use whistles in lieu of bells, and to connect
the whistles by means of tubes to hollow collapsible balls. of india-rubber
within the vehicles, so that by collapsing the balls air will be forced
through the tubes to blow the whistles.

filed by the said Thomas Evans Lundy and John Lingard Dunham
in the Great Seal Patent Office on the 19th May 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, WC, THOMAS
EVANS LUNDY and JOHN LINGARD DUNHAM, both of No. 166, City
Road, in the County of Middlesex, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of November, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Thomas Evans Lundy and John Lingard
Dunham, Her special licence that we, the said Thomas Evans Lundy and
John Lingard Dunham, our executors, administrators, and assigns, or such
others as we, the said Thomas Evans Lundy and John Lingard Dunham,
our 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 "NEW
OR IMPROVED MEANS OF COMMUNICATION BETWEEN PASSENGERS IN CABS, PRIVATE
CARRIAGES, OMNIBUSES, TRAMROAD CARS, AND OTHER SUCH LIKE VEHICLES, AND
THE DRIVERS OR CONDUCTORS THEREOF," upon the condition (amongst others)
that we, the said Thomas Evans Lundy and John Lingard Dunham, our
executors or administrators, by an instrument in writing under our, 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 we, the said Thomas Evans Lundy and John
Lingard Dunham, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly.
described and ascertained in and by the following statement:-
-
This Invention consists in the use of signal boards, discs, or plates of
any convenient form without or outside the vehicle; such signal boards,
discs, or plates are operated by means of levers or rods within the
vehicle. One or any number of signal boards, discs, or plates may be

page_text: used, and when more than one is employed they may be coloured or
lettered, so that each separate signal board, disc, or plate shall signify
or convey to the driver or conductor of the vehiclo a different signal
or command, such as stop, go on, right, left, slow, faster, or signals or
commands of other import if necessary; or the signals may be painted or
engraved both externally and internally, and an indicator pointer without
may be made by suitable gearing to follow the movements of a travelling
lever handle pointer within by means of communicating shafting, levers,
wheels, pulleys, or other gearing. The part of the vehicle at which the
external signals are fixed will be determined by the particular kind of
vehicle in which they are used; for instance, in cabs and ordinary road
carriages where the driver sits in front, the signals may be exhibited on
or above the dashboard facing the driver, while in omnibuses or tram-
road carriages they may be exhibited to the conductor at the rear
thereof, who may then communicate by like means to the driver; or in
this case the connection may be so arranged with a double set of signals
as to convey the like commands simultaneously to both conductor and
driver. It is proposed in some instances to fit the signal boards, discs,
or plates, or the rods or levers carrying the same with a tongue, which
by passing over ratchet teeth causes a rattling noise to call the attention
of the driver or conductor to the fact that he is being signalled to; or
the signal boards, discs, or plates, or their rods or levers, may carry the
ratchet teeth and the tongue may be fixed.
In order that the nature of our said Invention and the manner in
which the same is to be performed may be particularly described and
ascertained, we append to this Specification a Sheet of Drawings having
figures and letters of reference marked thereupon, the like letter being
used to denote a similar or corresponding part in each Figure.
These Drawings represent the application of our Invention to a
Hansom cab.
Figure 1 is a sectional view through a portion of the cab from the
back, and Figure 2 is a side view of the same cab partly in section.
In this application of our Invention one external visible signal only
is employed, and is in the form of a hand or pointer A set or secured
upon the shaft B in front of the cab. The shaft B passes into the interior
of the cab, where the bracket C forms bearings or journals for the shaft
to turn in, the other bearings or journals being at D. Upon another

page_text: bracket E in the interior of cab (E, Figure 1) is fixed a lever handle F
with a knob G and pointer F¹. At the side of cab is a quadrant shaped
plate of metal or quadrant shaped piece of any suitable material, upon
which is engraved, say, for example, three signals as shown, "left,"
"stop," "right."
In the Drawing the connection between the external visible signal A
and the internal pointer lever handle F, F', is made by making an eye upon
the lever F, into which is secured the end of the chain H, which passes
around the sheave on shaft B, so that any movement of the pointer lever
handle F, F, is instantaneously communicated to the same extent to the
shaft B and pointer A. Mitre or bevel wheels may be used for the same
purpose. The external half disc or dial I may or may not be engraved
with the signals. It may be understood that when the external pointer A
turns to the right hand, following the movement of the pointer handle
F, F, the driver is to direct his course accordingly, and the same with
regard to the left hand, while when the pointer is in the position
shown it shall indicate that the driver is to stop. At K is a spring,
which whenever the signal has been made and the lever F released
brings the pointer A to the position shown by dotted lines in Figure 1.
As the pointer moves around the half disc or dial I a metallic tongue M
travelling therewith passes over projections or ratchet teeth on I, and
causes a rattling noise to call the attention of the driver.
It will be obvious that the exact arrangement of the connection
between the internal and external siguals will vary according to the
kind of vehicle to which our Invention is applied. The Drawings will
clearly show the general mode of application.
In lieu of the ratchet arrangement herein-before mentioned, bells or
gongs may be employed in connection with the herein-before described
arrangements, and any given number of strokes, as may be agreed upon,
upon the bell or gong may convey signals or commands of import
corresponding with the external visible signals.
In some vehicles it may be found more convenient, and we propose
to use whistles in lieu of bells, and to connect the whistles by means of
tubes to hollow collapsible balls of india-rubber within the vehicles, so
that by collapsing the balls air will be forced through to blow the
whistles.

page_text: Having now particularly described the nature of our said Invention,
and the manner in which the same is to be performed, we wish it to be
clearly understood that what we claim as our Invention is, the means of
communication as described in this Specification, or in the accompanying
Drawings illustrated.
In witness whereof, we, the said Thomas Evans Lundy and John
Lingard Dunham, have hereunto set our hands and scals, this
Eighteenth day of May, in the year of our Lord One thousand
eight hundred and seventy.
THOMAS EVANS LUNDY.
