PROVISIONAL SPECIFICATION.
Improvements in Detachable Lamp Brackets for Bicycles, Tricycles,
and other Velocipedes.
I, FREDERICK THOMAS HARROP, of 2, Eden Place, Austin Street, Nechells,
Birmingham, in the County of Warwick, Press Tool Maker, do hereby declare
the nature of this invention to be as follows:-
This invention has reference to those brackets which are used on the front part
of a bicycle, tricycle, or other velocipede, for carrying the lamp and consists in
forming the said bracket out of sheet metal thus making a cheaper and lighter
bracket than those brackets having parts made of cast iron, also my improved
bracket is very easily attached and detached to or from the machine.
In carrying out my invention I make the said bracket which is formed in two
parts out of thin sheet metal stamped to the proper shape and afterwards bent to
form the said parts. In describing the back part of the bracket that clips round
the head of the machine I take a piece of metal of suitable length to go round
the head and then from each end I form two narrow ears or projecting pieces of
a suitable length and bent outwardly from the part that clips round the head to
about parallel to each other. The top and bottom edges of the said ears are bent
outwardly to form top and bottom grooves for the ears on the front part of the
said bracket to slide in, or the grooves may be formed on the front part that
carries the lamp and the ears on the back part made plain to suit them.
In describing the front part of the bracket I form a main portion of sheet
metal with two long arms carried from the bottom edge at right angles to the
main portion, I then bend in a suitable way the two long arms till they meet, the
ends forming two ears which slide in the aforesaid grooves formed on the ears of
the back part. The said main portion of the front part is bent a little forward
for receiving the lamp and both its edges are bent to form rounded edges to
prevent the rubber on the lamp from being cut or otherwise damaged.
The said front and back parts which form the bracket are secured together by
means of one, or more screws and thumb nuts or bolts, passing through holes
formed in the ears, or instead of one or more holes I may use a slotted hole for
adjusting the bracket, the bracket being clipped on to the head part tightly when
the two parts are screwed together.
I prefer to cut a long hole in the metal of the back part that clips the head to
give a better spring when.attaching or detaching the bracket from the machine
head. I also prefer to cut away the metal in the main portion of the front part
for lightening the bracket.
For attaching the said bracket the back part is, sprung over the head of the
machine and the ears of the same are then pressed together to slide into the
grooves formed on each side of the ears of the front part after which the bracket
is tightened up by means of one or more screws and is made to clip the head part
very firmly.
In a modification of my improved bracket instead of making the ears on the
back part flat I may make them half round to form a tube and the ears on the
front part to be half round to fit in the same.

Improvements in Detachable Lamp Brackets for Bicycles, Tricycles,.
and other Velocipedes.
I, FREDERICK THOMAS HARROP, of 2, Eden Place, Austin Street, Nechells,.
Birmingham, in the County of Warwick, Press Tool Maker, 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 :-
This invention has reference to detachable lamp brackets of the kind which is
used on the front or head of a bicycle tricycle or other velocipede for carrying
the lamp and consists in forming the said detachable lamp bracket from thin sheet
metal blanks in the manner herein described by which I am enabled to make a
cheap light and strong lamp bracket which can be very readily attached to or
detached from the machine.
I will describe my invention by referring to the accompanying drawing on
which Fig. 1 is a general view of a detachable lamp bracket constructed according
to this invention; Figs. 2 and 3 shews the two parts of the said lamp bracket
separately; Fig. 4 shews a strengthening plate for the front part of the said lamp
bracket and Fig. 5 illustrates a slightly modified form of my invention.
The same letters of reference indicate the same or corresponding parts in all
the figures.
My improved detachable lamp bracket consists essentially of two parts namely
a back part or clip A adapted to clip the head or front part of the bicycle or
other velocipede and a front part B on to which the socket part at the back of the
lamp fits this front part B being made to fix to the back part A. The back
part A consists of a sheet metal blank of the shape which will be understood from
an examination of Fig. 3 bent at a¹ to a circular form to clip the head of the
machine and having at each end two narrow ears or projecting pieces marked
respectively a² a bent outwardly from the clip part a¹ and somewhere about
parallel with each other. The top and bottom edges at a³ of the ears a² a³ are
bent outwardly so as to form top and bottom grooves for the ear parts 63 64 of the
arms of the front part B to slide in. The front part B of the detachable
lamp bracket consists of a sheet metal blank the shape of which will be understood
from Fig. 2 forming an upwardly inclined projecting part 65 with parallel sides
and made of the proper width to fit into the socket part of the lamp. The sides
of the part 6 are by preference folded back as shewn to form rounded edges to
prevent the rubber on the lamp from being cut thereby. At the lower part of
the front B there are two arms which are bent backwardly till their ends
almost meet where they form the two cars 63 which slide in the grooved ears a² a³
of the back part A and they are there secured by the cross bolt C which passes
through holes in the ears 636 and through holes a in the ears a² a³ thus securing
the two parts A and B together.
In attaching the lamp bracket above described to the head of a safety bicycle
or other velocipede, the screw C has first to be removed and the part B slided
away from the part A. The latter can now be opened and sprung on to the
head or front part of the bicycle so as to clip the same, the cars a² a³ are then
pressed together and the ears 6³ 6 of the fore part B are then slided into the
grooves a a³ and the bolt C is inserted through the holes and tightened up thus
securing the clip part A firmly to the head of the machine and also fixing the
parts A and B together. The lamp bracket is readily removed by first removing
the bolt C.
.
The back part A is by preference made with a long hole a' in the clip part so
as to enable it to bend more readily when being attached to or detached from the
1.ead of the velocipede, and the front part B is by preference pierced with a

page_text: hole 67 so as to lighten the same. The front part B may if desired be strengthened
by having an additional plate 68 (shewn separately by Fig. +) fixed to it by the
edges of the main portion B being closed over the same.
It will be evident that instead of the ear portions a² a³ of the clip part A
being made grooved as shewn by Figs. 1 and 3 and the ear parts 63 64 of the
front part B being made to slide within the same, this construction may be
reversed, that is to say, the ear portions 63 64 may have their edges turned over
to form grooves and the ears as a³ of the clip part A be made parallel to slide
within the same.
In a further modification of my invention the ears a³ a³ of the part A are as
shewn in Fig. 5, made of a half round tubular form and the ears 63 64 of the front
part B are made of a similar half round tubular form to fit within the ears a² a
or be there secured by the cross bolt C.
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. A detachable lamp bracket, for carrying a lamp from the front of a bicycle
or other velocipede, made from sheet metal and consisting essentially of two parts
namely a spring clip part adapted to clip the head of the bicycle or other
velocipede and an upwardly projecting front part to take into the lamp socket both
of these parts being made with ears adapted to engage together.and secured by
a cross bolt passing through the ears all substantially as herein before set forth.
2. In a detachable lamp bracket for carrying a lamp from the head of a safety
bicycle or other velocipede the combination of the clip part A adapted to clip
the head of a safety bicycle or other velocipede and the front part B to engage in
the socket of the lamp, these parts being constructed and adapted to engage
together and be secured by the cross bolt C in any of the several ways
substantially as hereinbefore described and illustrated by the accompanying
drawings.
