Improvements in the Manufacture of Brackets, Carriers, or Supports
for Lamps.
We WILLIAM BOWN of Summer Lane, Birmingham in the county of Warwick,
Manufacturer and ROBERT BENJAMIN CHALMERS of New John Street West,
Birmingham aforesaid, Lamp Maker do hereby declare the nature of this invention to
be as follows:-
Our improvements relate more particularly to brackets or carriers for supporting
or carrying lamps for bicycles or tricycles, and we will describe our improvements as
applied to brackets for supporting a lamp at the head or other suitable part of a
bicycle or tricycle but by suitable modification they may be applicable for other
purposes.
Our improvements consist firstly in securing or attaching to the lower part of
the upright portion of the bracket upon which the lamp is supported a spring formed
from a flat piece of steel or metal carrying the same upwards and level with the top
and sides of the bracket. At the upper portion of the said bracket we drill and tap a
hole and insert a screwed pin in the same, the end of which pin abuts against the flat
side of the spring so that when attaching the lamp to the bracket or support the
upright portion and spring is passed through the loop or socket of the lamp usually
lined with india rubber and by screwing forward the pin before named the spring is
forced apart from the bracket thereby compressing the rubber (when rubber is used)
or so filling up the space in the loop or socket as to form a very firm and rigid
connection doing away with all shake and vibration.
Secondly our improvements consist in hinging or jointing the bracket or support
at the curved or angled part the pin forming the axis having a head or projection at
one end and a nut or other equivalent screwed on at the other so that the lamp
supported on the said bracket may be put at any desired angle the screwing up of
the nut securely holding the bracket carrying the lamp in that position the unscrewing
of the nut will permit the angle of the bracket carrying the lamp to be varied as
desired.

Improvements in the Manufacture of Brackets, Carriers, or Supports
for Lamps.
We, WILLIAM Bown, of Summer Lane, Birmingham, in the county of Warwick,
Manufacturer, and ROBERT BENJAMIN CHALMERS, of New John Street West,
Birmingham aforesaid, Lamp 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:-
Our improvements relate more particularly to brackets or carriers for supporting
or carrying lamps for bicycles or tricycles.
We will describe our improvements, by way of example, as applied to brackets for
supporting a lamp at the head or other suitable part of a bicycle or tricycle but it will
be obvious that by suitable modifications the brackets or carriers can be made
applicable for supporting or carrying other lamps.
In order to enable our invention to be fully understood we will describe how it can
be carried into practice by reference to the accompanying drawing in which
Figures 1 and 2 are respectively a side elevation and a central longitudinal section
of the back portion or socket of a bicycle lamp applied to a bracket or support made
according to the first part of our invention.
Figures 3 and 4 are side elevations of the said bracket or support.
Figure 5 is a perspective view drawn to a reduced scale of a bracket or support
made according to the second part of our invention.
Figure 6 is a side elevation of a modification of the bracket or support shewn in
Figure 5.
Similar letters in all the figures indicate similar parts.
Referring to figures 1 to 4 our invention consists firstly in securing or attaching to
the lower part of the upright portion of the bracket b upon which the lamp is supported
a spring c formed from a flat piece of steel or other suitable metal the said spring c
extending upwards level with the top and sides of the bracket or support b. In the
upper portion of the said bracket or support we drill and tap a hole and insert a screw
threaded pin d in the same, the end of which pin abuts against the flat side of the
spring c.
When attaching the lamp to the bracket or support 6 the upright portion and spring
are passed through the loop or socket a at the back of the lamp the said loop or
socket being usually lined with india-rubber, as shewn clearly at a in figure 2. By
screwing forward the pin d the spring c is forced apart from the bracket or support b
thereby compressing the rubber (when rubber is used) or so filling up the space in
the loop or socket a as to form a very firm and rigid connection.
In figure 3 the spring c is shewn in its normal position before being forced apart
from the bracket or support 6 by the pin d whilst in Figure 4 the spring c is shown
forced apart from the bracket or support b.

page_text: We will now describe by reference to Figure 5 the second part of our invention
which consists in hinging or jointing the vertical part of the bracket or support b at f
to the horizontal portion the pin forming the axis of the hinge having a head or
projection g at one end and a nut h (or its equivalent) screwed thereon at the other
end so that the lamp supported on the bracket 6 can be placed at any desired angle
the vertical portion of the bracket carrying the lamp in that position being secured by
tightening up the nut h. By unscrewing the nut h the angle of the said portion of
the bracket carrying the lamp can be varied as desired.
The bracket or support shewn at Figure 6 is similar to that herein before described
with reference to Figure 5 with the exception that the vertical portion thereof is set
and secured at the required angle by means of nuts i and ; which are screwed onto a
curved screw-threaded pink working in a hole in the horizontal portion of the bracket
or support b, the head g and nut h shewn in Figure 5 not being then required; the
dotted lines indicate as an example how the angle of the vertical portion of
the bracket can be so varied.
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 manufacture and use of brackets or supports for carrying or supporting
lamps substantially as hereinbefore described with reference to figures 1, 2, 3 and 4
of the accompanying drawing.
a
2. The manufacture of brackets or supports for carrying or supporting lamps with
hinge or joint substantially as and for the purpose hereinbefore described with
reference to figures 5 and 6 respectively of the accompanying drawing.
3. The improved brackets or supports for bicycle and like lamps hereinbefore
described with reference to the several figures of the accompanying drawing.
