PROVISIONAL SPECIFICATION.
Improved Construction of Heads of Carriage, Cycle, and other
Lamps.
I, HENRY SALSBURY, of 125 and 126 Long Acre, London, Lamp Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to certain mode of manufacturing heads of lamps.
According to a well known method of making heads of lamps, they have been
formed from several pieces of stamped metal held in position by pillars or by
vertical pins or studs for the free escape of the fumes and products of combustion
from the flame.
The object of my invention is to employ fewer pieces of metal and in lieu of
connecting the pieces by studs I spin a roofing to the required shape after piercing
the blank with the necessary notches, slots, or apertures in what is to form a band
below the top of the shell, the bottom edge in the spinning being beaded for the
reception of a second or lower band by a burring or beading down operation, said
lower band forming part of the neck, also spun, and shaped for securing to the
lamp body by its splayed out base.
Before the two parts are beaded, I insert a flame or weather screen within and
between them to prevent down draughts and flickering.
The head may be in halves or sections and be made to meet at the edge rabbets
when folded or closed together.

Improved Construction of Heads of Carriage, Cycle, and other
Lamps.
I, HENRY SALSBURY, of 125 and 126 Long Acre, London, Lamp Manufacturer,
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 relates to certain mode of manufacturing heads of lamps.
According to the well known method of making heads of lamps, they have been
formed from several pieces of stamped metal held in position by affixable pillars
or by vertical pins or studs to form spaces for the free escape of the fumes and
products of combustion from the flame.
The object of my invention is to employ fewer pieces of metal, and in lieu of
connecting the pieces by studs, I spin a roofing to the required shape and pierce the
blank with the necessary notches, slots, or apertures in what is to form a band

page_text: below the top of the shell, the bottom edge in the spinning being beaded for the
reception of a second or lower band or neck by a burring or beading in or down
operation, said lower band being shaped to receive a shoulder also spun and
provided with a flange for securing the head to the lamp body.
Before the two parts i.e. the roof and neck, are beaded, I insert a flame
or weather screen within and between them to prevent down draughts and
flickering.
My invention will be clearly understood on reference to the annexed drawings.
Figure 1 represents a perspective sectional elevation of a lamp head top produced
by the spinning process but with the side or vapour escape holes stamped out, this
being performed after the spinning.
Figure 2 is a similar perspective sectional elevation with a spun neck, a wind
guard, and a false roof affixed in position.
Figure 3 indicates a spun shoulder with a couple of spring pins or studs which
when located in a beading or annular recess of the neck enable the head and neck
to have a rotative motion and thus be less liable to injury than the rigidly fixed
heads at present fitted on lamps.
Figure 4 elevation of a complete lamp head of my invention and ready to be
rivetted or otherwise secured by its flange on the body of a lamp, the dotted lines
showing one of, the springs which locate the shoulder to the neck.
A is the top of the head spun from a single piece of metal with the necessary
moulding or shaping, as at B, and with a band C and two bead rings D, E, as at
Figure 1, one to receive the smut catcher or false roof F, and the other to receive
the wind guard G, as at Figure 2, these being of disc or washer like formation and
sprung into place in the beads D, E, respectively, where they become pinched in
contact and securely held.
H is the neck shaped by spinning or by rolling a ring to the shape required.
The upper end is formed with a lip I which when sprung into place fixes the parts
together in a secure manner. J is a shoulder also spun to shape and provided with
a flange K to enable the head to be rivetted on the body of a lamp.
L, L, are a couple of spring actioned studs which project through holes in the
shoulder to engage in the annular recess M of the neck to allow of the upper head
being turned and so prevent injury.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The herein before described improved construction of heads of carriage, cycle,
and other lamps by the spinning operation, as set forth.
2. Constructing the beads of carriage, cycle, and other lamps in three parts all
produced by the spinning operation and substantially of the shapes shown in the
annexed-drawings, the parts being connected in the manner and for the purposes
set forth.
