1, FREDERICK JOHN BORLAND, of Sheepscar Grove Works, in the City of
Leeds, Electrician, do hereby declare the nature of this invention, to be as
follows
According to my improvements the tapes or bands forming the conducting discs
or rings used in combination with a pin wheel or what is known in the trade as the
"cheese" wheel or the revolving part of the roundabout are made or provided
with a projecting edge or section, which may be V shaped, or half round or
otherwise.
Arranged in connection with such discs or rings are wheels or runners carried
by arms, rods or levers (for conveying the current to the tapes or bands aforesaid)
the up and down movement of which is regulated by springs or other suitable
device, so as to keep the said runners or wheels in contact with the said tapes or
bands as they rise and lower which motion is caused by the revolution of the
"cheese" wheel and the parts connected therewith.
The said wheels or runners are carried by suitable means from a tube which is
fixed on a post, or the wheels or runners may be fitted to the revolving part, and
the tapes or bands are fixed or remain stationary. The conductors or wires from
the dynamo are joined up to the tube and its connections and from there to the
lamps.
For rapidly making the connections between the wires I employ a special
construction of socket and plug by which the circuit is quickly and readily
made.
One socket and plug is fixed on the lamp body and another to the frame of the
roundabout.
Also the resistance coils, which have, bitherto been a source of much waste of
time in the taking down or putting up of roundabouts and the like, I arrange upon
the lamp frame or cover so that they form a permanent part of the lamp, or I
arrange such upon the framework of the roundabout.

COMPLETE SPECIFICATION.
Improvements in and connected with Apparatus for Lighting Up
Roundabouts and the like by Electricity.
I, FREDERICK JOHN BORLAND, of Sheepscar Grove Works, in the City of
Leeds, Electrician, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
.
My invention has reference to apparatus for electrically lighting up roundabouts

page_text: Fig. 1. is an elevation, partly in section, showing my improvements applied to
roundabout having revolving top.
Fig. 2, is a plan of my improved apparatus or arrangement carrying the runners
or wheels for completing the circuit between them and the tapes or bands on the
revolving wheel.
Fig. 3, is an elevation of Fig. 2.
According to my improvements the tapes or bands A for ning the conducting
discs or rings used in combination with a pin wheel or what is known in the trade
as the "cheese" wheel, B, or the revolving part of the roundabout, are made or
provided with a projecting edge or section C, which may be V shaped, half round,
or otherwise.
Arranged in connection with such discs or rings A are wheels or runners D
carried by arms, rods, or levers E (for conveying the current to the said tapes or
bands Athe up and down movement of which is regulated by springs, or other
suitable device, so as to keep the said runners or wheels in contact with the said
tapes or bands A as they rise and lower, which motion is caused by the revolution
of the "cheese" wheel B aud the parts connected therewith. The arms, rods.or
levers E of the said wheels or runners D are carried by insulated studs D' from
arms Hand J forming part of the boss G which is carried on a tube or hollow
post K, which acts as a support.
Or the wheels or runners D may be fitted to the revolving part and the tapes or
bands A are fixed or remain stationary.
The conductors or wires H¹ and Jare joined up through the tube K, and to the
studs D' and from there, the current passes through the connections to the lamps H³
by wires H and H.
The arms, rods, or levers E carrying the wheels or runners D have pivotted to
them at L coupling pieces M, in the form of a fork which is joined (by a loose
or swivel joint) to bosses N having holes N¹, and set screws N2, for securing such
upon the insulated studs D' and joining them to the arms H and J. The said
boss N has also a turned over part O fitted with screws P from which spiral
springs R are joined to the ends S of the arms, rods, or levers E. Pivotted on
the centre L, or cast to the coupling piece M is a bracket. T having a slot T¹ with
pin U hand spring U₁ and spring bolt V by which means the position or angle of
the arm, rod or lever E, can be regulated or altered.
When it is desired to change or put the wheels or runners D out of contact
with the said tapes or bands A, the arm or lever E is pulled or pushed until the
pin U, in the slot T', clears the spring bolt V, by forcing such back until the pin U
has passed when the spring bolt V returns to its normal position, and locks the
pin U.
When it is desired to unlock the pin U and return the arm or lever E
to the position shown in full, the hand spring U' is pulled back which withdraws
the spring bolt V, and the pin U, (which is carried in the arm or lever E) is free
to be moved in the slot T' to any position required.
For rapidly making the connections between the wires I employ a special
construction of socket and plug (such as the "concentric") by which the circuit
is quickly and readily made or broken.
The said socket consists of a base and cap or cover of insulating material. The
said base has two terminals one connected with a central split pin forming one pole,
the other terminal is connected to a ring which is concentric with the said split pin
and forms the other pole. The terminals of the socket are connected to the main
wires or cables.
The said plug consists of two concentric tubes mounted on, an insulated base
having two terminals connected with the concentric tubes. The terminals of the
plug are connected to the flexible cords or wires.
When the plug is inserted into the socket, the inner concentric tube in the plug

page_text: fits on to the split pin in the socket, and the outer concentric tube fits into the
concentric ring around the split pin, thus connecting the two terminals of the socket
with the two terminals of the plug.
This construction is known, in the trade, as the "concentric" plug and sooket.
One socket W and plug X is fixed on the lamp body, and another to the frame
of the roundabout.
Also the resistance coils, which have hitherto been a source of much waste of
time in the taking down or putting up of roundabouts or the like, I arrange upon
or in the lamp frame Y so that it forms a permanent part of the lamp; or I may
arrange such upon the framework of the roundabout.
By means of my invention or improvements set forth a perfect and positive.
contact of the tapes or bands with the runners or wheels is obtained, with a
minimum of wear and tear, also the runners or wheels can be readily put in and
out of contact with the tapes or bands, which is a great advantage during day
time.
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 :-
1. The combination with the wheel B of tapes or bands A, engaging with the
wheels or runners D in such a manner that the said wheels or runners cannot-
slip off the said tapes or bands A, when in action, substantially as shown and
described.
2. The construction and arrangement of means for carrying the runners or
wheels D, substantially as set forth.
3. The combination with the pipe K of the boss G, arms H and J, insulated
studs D' for supporting the lever mechanism carrying the wheels or runners D,
substantially as shown and described.
4. The combination with the tapes or bands A of runners or wheels D carried
by arms or levers E whereby a positive contact is obtained, substantially as set.
forth.
5. In apparatus for electrically lighting roundabouts, the combination of plug X
and socket W for readily connecting and disconnecting the lamps to the revolving
tapes or bands A, as shown and described.
6. The combination of parts forming my improvements in or connected with
apparatus for electrically lighting roundabouts, and the like, substantially as set
forth.
