of Surry and WILLIAM RAWORTH Brassfinisher of 1 Brunswick Street Kings Cross
in the County of Middlesex do hereby declare the nature of our Invention for
IMPROVEMENTS IN. REMOVEABLE KEY SWITCHES APPLICABLE TO FITTINGS FOR
ELECTRICAL LAMPS AND OTHER PURPOSES to be as follows:-
Our Invention consists of an electrical moveable key Switch, especially suited to
be used in connection with electrical lamps, for turning on & off the electrical
currant. The Key is constructed of insulated material, knob shape, with a cased
spiral spring to give additional power for a sure connection, for the electrical
currant with two pieces of metal, termed wards, fixed at the end of the key, for
the positive and negative wires to be attached. We fix two metal discs, with raised
sloping flanges in an insulated material box, with a slot cut to allow the wards of
the key to be inserted in the slot, to travel up the sloping raised flanges, to arrive
in its properly sunk seating, the key is held secure by means of the cased spiral
spring in the key. The Key is seperate from the box and can be removed at will,
so as not to allow persons to tamper with the lamps.

We GEORGE RICHARDSON of 39 Nursery Rd Brixton in the County of Surrey
and WILLIAM RAWORTH of 1 Brunswick, Street, Kings Cross in the County of
Middlesex do hereby declare the nature of our invention for IMPROVEMENTS IN
REMOVEABLE KEY SWITCHES APPLICABLE TO FITTINGS FOR. ELECTRICAL LAMPS
AND OTHER PURPOSES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
+
Our Invention consists of an electrical moveable key Switch especially suited to
be used in connection with electrical lamps, for turning on and off the electrical
currant. The Key is constructed of Wood or insulated material, knob shape, with a
cased spiral spring to give additional power for a sure connection for the electrical
currant. Fixed to this key at the opposite end of the knob is two pieces of metal
termed wards, for the positive and negative wires to be attached these wires are
screwed or otherwise, fixed to the wards of the key. We fix two metal discs with
raised sloping flanges, in a circular or cylinderical shape box lid or cover, made of
insulated material with a slot cut in the top portion of the lid or cover to allow the
wards of the key (the key being seperate from the box and can be removed at will
so as not to allow person to tamper with, the lamps) to be inserted in the slot, to
travel up the sloping raised flanges, to arrive in its properly sunk seating the key
is held securely by means of the cased spiral spring fixed on the shank portion of
the key and thus gives the desired connection. We now describe the drawings as
follows: Figure 1 marked A denotes the part of the box, B the slot to insert the
key. Figure 2 marked D the back of the box. B the slot where key passes through,
C the half disc of metal plates with raised sloping flanges F, E connecting screw
I Positive wires, H negative wires. Figure 3 marked C is the side of the box with
key inserted K. J, cased spiral spring, H negative wires Figures 4 denotes a section
of the key inserted in the box fixed, K is knob of key, O is the shank of Key, J is the
cased spiral spring, L is the spiral spring, B is the slot in box, C the half disc metal plate
with raised sloping flanges, E connecting screws, I Positive wire. Figures 5 and 6
denotes the removeable key plug, marked K the knob, O the shank, J cased spiral
spring, N N wards of key plug; L spiral spring. Figures 7 and 8 denotes the
removeable key with the positive & negative wires attached to the wards marked N N
by means of the connecting screws E. E. marked.M is the two insulated wires. The
-

page_text: contact is made through the wards of the key marked N being inserted in the slot B
and sliding up the sloping flang half disc F to fall in its sunk seating as described
with dotted line on Figure 4. The drawings referred to are those accompanying the
Provisional Specification.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, We declare that what
we claim is:-
1. The arrangement and combination of the two pieces of metal termed wards,
with the positive or negative wires attached or otherwise, and the spiral spring
enclosed in a box, made moveable on the shank of the key, substantially in the
manner herein described and illustrated in the accompanying drawings.
2. The arrangement and combination of the two metal discs, with raised sloping
flanges, with a sunk seating to receive the wards of the key fixed at the back of the
circular or cylinderical shape box lid or cover, substantially in the manner herein
described and illustrated in the accompanying drawings.
3. The method of and apparatus for-preventing persons to tamper with the
electrical currants, by the construction of the key, of the shape shown in the
accompanying drawings, being removeable in the manner herein described and
illustrated in the accompanying drawings.
Dated this 20th day of November 1884.
