PROVISIONAL SPECIFICATION.
Improvements in Supports or Holders for Bicycle and Tricycle
Lamps.
JOHN HAWKINS Carlton Terrace, Hornsey Road London N. Manager of Bicycle and
Tricycle Works do hereby declare the nature of this invention to be as follows:-
The object of my invention is to make a flexible support for Lamps formed so as to
yeild to the vibration on a rough road which by its springy nature grips or holds the
Lamp securely to itself. This I do by forming my Holder out of one piece of rod
steel bent in the middle to form an Eye bringing the half portion or sides as they now
become nearly togather. Then between the Eye and the ends 1 form a coil in each
side of one or more turns according to the flexibility required. A part of the remain-
ing portion of the sides I bend up equally a few inches from the ends to form a part
to pass into the recess on the Lamps. These bent up parts are in no way connected,
so that they may be pressed closer togather to pass into the Lamp recess and when
released they fly apart pressing with considerable force on the inside of the Lamp
recess or socket thereby holding or gripping the Lamp firmly while the coil will yeild
to any jar or pressure in an upward or downward direction.

Improvements in Supports or Holders for Bicycle and Tricycle
Lamps.
JOHN HAWKINS Carlton Terrace Hornsey Road London N. Manager of Works
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:-
The object of my Invention is to make a Flexible support for Lamps formed so as
to yeild to the vibration on a rough road which also by its springy nature grips or
holds the Lamp securely to itself. I effect this object by forming my holder-support
or Bracket out of one piece of rod steel bent in the middle to form an eye bringing
the half portion-or sides as they now become nearly togather.
Then beween the eye
& the ends I form a coil in each side of one or more turns according to the flexibility
required but the coils are not absolutely necessary if the Lamp be weighty enough to
spring the bracket if made with straight sides. A few inches from each end I bend
up a portion to pass into the recess or socket on the Lamps. These bent up parts are
not joined togather but left free so to have independant action allways so that they
may be pressed closer togather to pass into the Lamp socket and when released they
fly apart pressing on the inside of the socket thereby gripping or holding the Lamp
firmly to itself while any jar or pressure in an upward or downward direction will
cause the Bracket to yeild. In order to make my invention fully understood I shall
proceed to refer to the sheet of drawings accompanying this specification.
Observing that the same letters refer to similar parts in the different figures.
Fig. 1. shows the rod of steel bent in the middle to form the eye A and the ends
turned up at B B to pass into the Lamp socket. The rod steel I prefer to use is of a
flat section and bent at A flatways keeping the edges at top and bottom but at a short
distance from A namely at CI twist it a quarter turn making the flat sides come at
top & bottom thus I strengthen the bracket round the eye while making the other
part more flexible in an upward and downward direction. It will be apparent that BB
can be pressed close togather to pass them into any Lamp recess or socket and that
they will then spring apart gripping the inside of the socket tightly. If there is not
room to fit a support or Bracket of the length shown in Fig. 1. then I prefer to make
them of the forms shown in Figs. 2 and which reduces the length of the Bracket
by bending the sides as of Fig. 1. over or sideways to form coils thereby with the same
amount of steel rod used the space occupied by the Bracket is much reduced.
Fig. 4. 5. & 6 shew other ways of bending to form coils and loops to give the requisite
amount of Flexibility. In order to attach the Bracket to the frame of a Bicycle or
Tricycle I connect it with the special form of clip shown in Fig. 7. where D represents
the tubular frame of the machine and E¹ E' the clip formed in two parts to embrace
the tube D. The part E' carries the bolt G which connects the bracket by its eye A.
The other part E is formed with a hook piece F for passing round the bolt G upon

page_text: which it turns as upon a hinge. The other ends of the clip have ear pieces H. H
through which passes a bolt I by the screwing up of which the parts E' and E' are
drawn togather and bound firmly upon the tube D. The clip is therefore readily detached
from the tube by removing the nut on I when the part E turning the hook piece F
from around the bolt G the parts separate and the whole comes away. Fig. 8. shows
another form of Bracket and clip, this is for Lamps having the socket formed on the
top, therefore it does not require the ends B B of the Bracket to be bent upwards.
The clip is formed in two parts in a similar manner to that in Fig. 7. but the upper
half has a projecting stud J screwed & fitted with a nut to attach the Bracket by the
eye A as usual. This clip will enable the Bracket to be attached to the Axle or Hub
inside a Bicycle or Tricycle wheel to carry a Hub Lamp or it may be fitted on any
horizontal pin or rod of a machine.
Having now described and particulary ascertained the nature of my Invention
I would have it understood that what I consider new and therefore claim as secured
to me is
Firstly. Lamp Brackets constructed of rod steel with the ends that pass into the
Lamp socket as B B left free and unconnected so that by the force of its springiness
it holds or grips the Lamp socket-substantically as described and shown Fig. 1. 2.
3. 4. 5 6. 7 & 8.
Secondly. Clips for attaching Lamp Brackets formed in two separate parts one
part hooked as I to pass round a bolt forming a hinge, so that the clip may be readily
detached or applied to any part of a Tricycle or Bicycle frame substantically as described
and shown Figs. 7 and 8.
