Improvements in Cycle Lamps.
We, JOHN PARKER and CHARLES HUDSON, trading as S. Parker, Hudson
and Company of Midland Works, Kings Norton, near the City of Birmingham,
Lamp Manufacturers, and JOHN HENRY SMITH of 115 Cooksey Road, Small
Heath, near Birmingham aforesaid, Foreman, do hereby declare the nature of this
invention to be as follows :-
This invention relates to detail improvements in cycle lamps, and consists, in the
one part, in improved bearings for the arms of the balanced backs, and in another
part, in a swinging and detachable body.
suitably
In carrying out the first part of our improvements, two pairs of arms,
braced together, are taken, with their ends being eyed or having bossed eyes for
taking upon the pivot ends of circular plugs or bushes, having annular stop collars,
and fitted and working within like-shaped sleeves (carried by strap or back plate
and socket plate respectively) as bearings.
The arms are cranked or set inwards at their middle parts and are tied or braced
together by plates or equivalents, whose ends are wrapped over and around the
said set-in middles, and by which means the bearing eyes of the arms are kept in
their assigned positions.
The back, which is provided with a coiled or other compensating spring for
taking the lamp back to its normal position after each oscillation, turns about the
pivot ends of the said inserted plugs or bushes as centres.
For cheap lamps, the bearing ends of the arms may be made into inwardly
directed hollow pivots, formed by press tools, such pivots may be split so as to
slightly expand and work freely within the bearing ends of the sleeves, whereby
rattling is prevented and cheapness in manufacture attained.
If necessary, the pivots may be split so as to slightly open out and prevent
rattling.
These bushed pivots, with stop collars may be made from wire, coiled into the
form of a spring helix with the pivot which passes through the bearings in
arms coming axially. The said bearings may be made of steel, gun-metal or other
suitable material.
As a further form of our improvements, we make the bearings of lamps
generally of plumbago, suitably prepared papier-mache or the like.
In carrying out the second part of my improvements, we the body, oil-container,
crown and bell together, with the said body being open at back and having a
knuckle sleeve or hollow beading upon the offside, and with a suitable catch at the
near side.
The back plate to which the spring arms are connected and to whose middle the
reflector is connected, has at its off side, a long upright pillar or stalk, which forms
the fulcrum upon which the knuckle sleeve of the horizontally swinging body
takes and turns. When the catch has been released, the lamp cau be turned
bodily horizontal and forwards, leaving the back open and leaving the interior of
the lamp open for lighting, trimming and cleansing purposes.
On the lamp being swung back, the catch is made to snap behind the said back
and secure the lamp in position.
The crown of the lamp is pierced for the outward passage of the products

coming above the piercings to prevent currents of air coming direct upon the
flame.

We, Joux PARKER and CHARLES HUDSON, trading as S. Parker, Hudson
and Company, of Midland Works, Kings Norton, near the City of Birmingham,
Lamp Manufacturers, and JoHN HENRY SMITH of 115 Cooksey Road, Small Heath,
Dear Birmingham aforesaid, Foreman, 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 detail improvements in cycle lamps, and consists, in
the one part, in improved bearings for the arms of the balanced backs, and in
another part, in a swinging and detachable body.
In carrying out the first part of our improvements, two pairs of arms, suitably
braced together, are taken, with their ends being eyed for taking upon the pivot
ends of circular plugs having annular stop collars, and fitted and working within
like-shaped sleeves (carried by strap or back plate and socket plate respectively)
as hearings.
The arms are cranked or set inwards at their middle parts and are tied or braced
together by plates or equivalents, whose ends are wrapped over and around the
said set-in middles, and by which means the bearings eyes of the arms are kept in
their assigned positions.
The back, which is provided with a coiled or other compensating spring for
taking the lamp back to its normal position after each oscillation, turns about the
pivot ends of the said inserted plugs or bushes as centres.
We make the body, oil-container, crown and bell together, with the said body
being open at back and having a knuckle sleeve or hollow bending upon the offside,
and with a suitable catch at the near side.
The back plate to which the spring arms are connected and to whose middle the
reflector is attached has at its off side, a long upright pillar or stalk, which forms
the fulcrum upon which the knuckle sleeve of the horizontally swinging body takes
and turns. When the catch has been released, the lamp can be turned bodily
borizontal and forwards, leaving the back open, with the interior of the lamp
accessible for lighting, trimming and cleansing purposes.
On the lamp being swung back, the catch is made to snap behind the said back
and secure the lamp in position.
The crown of the lamp is pierced for the outward passage of the products of
combustion, whilst the bottom of the body is pierced and may have a breaker
disposed above the piercings to prevent currents of air coming direct upon the
flame.
Figure of the accompanying drawing represents a cycle lamp provided with
bearings and a swinging and detachable back made according to our invention.
Figure 2 represents the back and bedy separated.
Figure 3 represents partly in section and partly in elevation, the back of the
lamp.

page_text: Figure 4 is a cross section upon the dotted line a Figure 3.
Figure 5 represents, in section and elevation, some of the component parts of the
said back separately.
The same letters of reference indicate corresponding parts in Figures 1 to 5 of
the drawing.
a is the body part of the lamp, surmounted by a pierced crown a', with a
combined base and oil tank a², and a glazed bell or light aperture a', and with the
back offside edge a', having a knuckle, sleeve or tubular bearing as, which takes
and works upon an upright stalk a, directed from the lower part of the offside
edge a', of the back strap as, which carries tubular bearing sleeves a, in the open
ends a, of which, the inner parts, of rotating stop-collared plugs or bearings b,
fit, with the collars 62, abutting up to the end edges a, of the said sleeves. are
pivot ends of the said plugs, upon which the eyed ends c', of inwardly cranked
arms c, take, the whole of the assembled parts being bound and secured together
and the bearings in their assigned positions by clip plates e², whose outer ends c³,
are wrapped transversely around the said arins.
The other eyed ends of the arms take upon the pivot ends of other bearings b,
taking into the ends d, of sleeves d², carried by the plate d³, of the socket d.
For cheap lamps, the bearing ends of the arus may be made into inwardly
directed hollow pivots, formed by press tools. Such pivots may be split so as to
slightly expand and work freely within the bearing ends of the sleeves, whereby
rattling is prevented and cheapness in manufacture attained.
Figure 6 represents in elevation and section, such an arm with split and bushed
ends.
Figure 7 represents an arm with plain bushed ends.
care the arms, with split bushed ends e, in Figure 6, and plain bushed ends c²,
in Figure 7.
These bushed pivots, with stop collars may be made from wire, coiled into the
form of a spring helix.
Figure 8 represents such a spring bushed arm in which c, is the arm made from
wire and c is the coiled spring ends, which are slightly larger in diameter than the
bearing sleeves into which they are to take, so that no rattling of the fitted part
can occur and all wear is automatically compensated by the expansion of the coils
which were slightly compressed when fitted into position.
As a further forin of our improvements, we make the bearings of lamps generally
of plumbago, suitably prepared papier-mache or the like.
Figure 9 represents a section of such a bearing.
Figure 10 represents a section and an elevation of the plumbago bush of the
bearing separately.
c is the plumbago bush lying in the end of the sleeve a, of the back strap or
socket plate and c' is the arm with a plug end c², taking into the said bearing.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
First. In the bearings of cycle lamps, making the same in the form of shouldered
or collared plugs with pivot ends or equivalent, and with the inner parts of the
plugs adapted to take within the ends of sleeves carried by the back plate and
socket plate or equivalents and the outer or pivot ends adapted to receive eyed
or equivalent parts of the supporting arms, substantially as described and set
forth.
Secondly. In the bearings of cycle lamps, the combination with plugs b, having
pivot ends &³, or their equivalent, of sleeve bearings of the back strap and socket
plate, substantially as described and set forth in Figures 1 to 5.
Thirdly. In cycle lamps, the improved construction of swinging and detachable
body with its accessories, substantially as described and set forth.
Fourthly. In cycle lamps, forming the ends of the supporting arms into split

page_text: or plain bushed bearings, substantially as described and set forth in Figures 6
and 7.
Fifthly. In cycle lamps, making the bearing ends of the supporting arms in the
form of coiled springs or helices for the purpose substantially as described and set
forth in Figure 8.
Sixthly. In cycle lamps, making the bearings e, of plumbago or papier-mache
substantially as described nud set forth in Figures 9 and 10.
