PROVISIONAL SPECIFICATION.
A System of Electrical Signalling or Communication between the.
Occupant or Occupants of a Cab, Carriage, or other Road Vehicle,
Propelled by Horse or other Power, and the Driver or Drivers
thereof, and Apparatus therefor.
I, WILLIAM PERREN MAYCOCK, of 30, Kemble Road, Croydon, in the County of
Surrey, England, Member of the Institution of Electrical Engineers, Electrical
Engineer, do hereby declare the nature of this invention to be as follows;-
This invention is for the purpose of providing a means of signalling or com-
munication between the occupant or occupants of a cab, carriage, or other road
vehicle propelled by horse or other power, & the driver or drivers thereof, whereby
the latter may be instructed when to turn to right or left, when to start or stop,
& so on. The apparatus therefor comprises two suitable electric bells, trumpets,
buzzers, or similar sounding devices preferably having different sounds or tones,
a primary or secondary battery, three pushes or similar contact makers, & con-
necting wires therefor. The three pushes or similar contact makers (see Fig.)
which we will call A, B, & C, are fixed in the interior of the vehicle, & are so
connected with the bells or sounding devices, that push A operates one bell, push B
the other bell, & push C both bells: a box containing the bells & battery being
fixed conveniently near to the driver, say under his seat. When the bell operated
by push A rings, the driver is to turn to the left; when the bell operated by push B
rings the driver is to turn to the right; when both bells ring (operated by push C)
the driver is to start or stop as the case may be. The method of connecting the
apparatus together is shewn in the drawing, where A, B, & C, are the three pushes
aforementioned; D, & E, the two bells; F the battery; & G, G, G, G, etc., the
connecting wires. It will be seen that the pushes A & B are of the kind known as
Morse or double-contact pushes, while push C is of the ordinary description. The
three pushes may be grouped together on one base, or they may be conveniently
fixed in separate positions as follows, say push A on the left-hand side of the
vehicle, push B on the right-hand side, & push C in the middle of the back or
front of the vehicle. The connecting wires may be either permanently fixed in the
vehicle, or may be easily removable.

Occupant or Occupants of a Cab, Carriage, or other Road Vehicle,
Propelled by Horse or other Power, and the Driver or Drivers
thereof, and Apparatus therefor..
I, WILLIAM PERREN MAYCOCK, of No. 30, Kemble Road, Croydon, in the County
of Surrey, Electrical Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
My invention relates to an improved system of electrical signalling or com- 5
munication between the occupant of a vehicle, and the driver thereof, and has for
it's object the provision of a distinctly audible signal or signals to said driver as
instructions to turn to the right or left hand, or to stop or start. And further I
may arrange the apparatus in a compact form, so that it may be easily and readily
applied to any existing vehicle without structural alteration.
In order that my invention may be clearly understood I have appended the
accompanying sheet of drawings, in which Figure. 1 represents the interior device,
or transmitter and Figure 2 the exterior device, being the receiver or sounder.
Figure 3 is a diagram of the connections. Similar letters of reference indicate
corresponding parts in the several views.
In carrying my invention into effect I enclose two bells of different tone, a bell
and buzzer or a bell and trumpet, or any combination whereby two different sounds
are produced, within a box or case A Figure 2, employing gauze or any open
work B upon one or more sides to allow the sound waves to pass freely. One or
more cells of a primary or secondary battery are also enclosed within said box or
case A and a triple contact socket is arranged connecting the bells, sounders, or
equivalents, and the battery, with a triple contact for exterior connection, pre-
ferably a plug C, with three concentric contacts a a¹. a corresponding to the three
wires of a flexible lead D also marked a a¹ a¹¹ This flexible lead being carried
into the interior of the vehicle, three separate pushes may be connected, fixed in
suitable positions inside the vehicle thereto, or I may, employ a case E Figure 1,
containing the three pushes b c and d, and make the necessary connections there-
from as shown by the flexible lead D, and hereinafter fully described with reference
to the diagram Figure 3: The pushes c and d are double contact pushes similar
to the ordinary Morse Key Type, and b is an ordinary push. When c is pressed by
the occupant of the vehicle, the driver is advised by the sound of its corresponding
bell; or equivalent device that he is to turn to the left, and when d is pressed the
indication is to turn to the right: The central push b. operates both, bells or
sounders simultaneously, and according to the position of the vehicle, indicates
starting or stopping.
..
..I may attach strap loops e. el to the transmitter for attaching it to the interio
of the vehicle, or screw staples f or any equivalent therefor, such as hooks fo
attaching to the cushions or other part of the vehicle, according to the requirement
of a temporary or permanent installation. Instead of employing a flexible lead
may run the wires as a permanent installation.
The whole arrangement of. the apparatus is designed to fit without encumbering
any known type of vehicle, and the various parts may be mounted in such a manne
as to minimise the vibration incidental to traction.
Referring to the diagram of connections, Figure 3, the wire a connects the bell
with the lever of the Morse Key c. The wire a connects the battery F with or
terminal of the push b and also with the two lower contacts of the Morse Keys
1

page_text: and d. The upper contacts of these Keys are normally in contact with the levers,
although this position is not necessarily shown by the drawing, and said upper
contacts are connected together, and also to the other terminal of the push 6 by
the wire g. The outer terminal of the bell H is also coupled to the lever of the
Morse Key d, by the wire a". Following the action of the Morse Key c operating
the bell G, the current passes from the battery F by the wire a¹ to the lower contact
of said key c thence through the lever, by the wire a to the bell, G, and by h back
to the battery, thus completing the circuit. The Morse Key d on being pressed
upon its lower contact connects the battery F through a to the lever, and thence
through the wire all to the bell H, the opposite terminal of which is connected to
the battery F by the wire h, thus completing the circuit. The normal position
of the Morse Keys c d being in touch with the upper contacts, the push 6 may be
operated. It is connected by the wire a¹ to the battery F, and through a to the
bell G, and all to the bell H, both of these bells being coupled together by
the other terminals and to the battery F, thus completing a double or divided
circuit through the two bells G H and the battery F through the push b.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
-
First. In an electrical signalling apparatus for vehicles, the combination and
arrangement of bells, buzzers, trumpets, or similar sounders, pushes, batteries,
and circuits therefor substantially as and for the purpose herein set forth, with
reference to the appended sheet of drawings.
Second. In an electrical signalling apparatus for vehicles, the combination of
two separate bells or sounders with three separate pushes or contacts for producing
separate signals, substantially as herein described, with reference to the appended
sheet of drawings.
Third. In an electrical signalling apparatus for vehicles, the method of and
means for arranging the electrical circuit connecting two bells or sounders with a
battery and three pushes, substantially as and for the purpose specified, and herein
described and shown by the drawings hereto appended.
