COMPLETE SPECIFICATION.
Improvements in and relating to Cycle Lamps, and in the
Manufacture of the same.
I, George Harry William Davis, trading as G. H. W. Davis & Co. of
Edgbaston Works, Gough Road, Edgbaston, Birmingham, in the County of
Warwick, Lamp Makers, do hereby declare the nature of my said invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
My invention has for its object improvements in and relating to cycle lamps by
which access to the interior of such lamps may be more readily obtained for the
purpose of cleaning same. I also render greater facilities for the more ready
attaching or detaching of the gates from the body. By my invention the reservoir
is cheapened and improved in manufacture. My improvements also consist of
means for facilitating the changing and cleaning of the reflectors and for protecting
them from becoming tarnished as well as increasing the reflecting power, all of
which accomplish without materially increasing the cost of manufacture.
In order that my invention may be clearly understood and more easily carried
into practise have appended hereunto a double sized sheet of drawings upon
which I have fully illustrated the nature of my said improvements together with
the means for carrying the same into effect.
Figure 1, is a general view of the lamp shown open.
Figure 2, is a side elvation of the gates.
Figure 3, is a vertical section through the gates.
Figure 4, is an elevation of one of the gates looking from the lamp.
Figure 5, is a cross section through the stampings for forming the oil vessels.
Figure 6, is an elevation of the oil vessel before being fixed to the lamp.
Figure 7, is an elevation of the back of a lamp having one of my removable diso
reflectors in position.
Figure 8, is a vertical section through same.
Figure 9 is a similar vertical section to Figure 8 but with the reflector
removed.
Figure 10 is a section through the bell reflector.
Figure 11 is an elevation of Figure 10.
Figure 12 is a diagram section through a lamp showing a new form of
reflector.
In carrying my invention into effect I form the body of my lamp of two parts A'
and A³ the part A' consisting of the front bearing the lease a side a® & top a
while the part A' consists of the back and reflector with side a to the lower part
of which is attached the oil vessel C. The front and top part A is hinged to the
side a' of the back and bottom part A* at a' so that the top and front part A may
be turned up and over in the manner shown by Figure 1 thus exposing the whole
of the interior of the lamp for cleaning purposes. The side is slotted at a' for the
burner spindle and at a for the purpose of engaging with any suitable catch a*.
For the purpose of being readily disengaged from the pins the gates B are provided
with the slots 6' so that they can be attached and detached without the necessity
of removing the pins F and nuts f¹. The gates B are secured in position by the
clips E each of which engage at el with both pins F of each gate. The gates B
are secured to the clips E by the screw H which passes through the gate and
engages with a threaded hole e' forined in the clip E by which means the clips E

between. The gates B can thus be taken off without interference with the pins F
by simply releasing the clip E by means of the screw H.
For the cheaper & more ready production of the oil vessel C I stamp the body
part in two halves C and C³ from the saine tools & of the same shape & these two
halves are soldered or otherwise fastened together as shown by Figure 6 the part
bead c³ being pressed over or under the part bead o so as to form the complete
reservoir Can aperture being cut out from the top for the reception of the
burner K.
In the case of the reflectors I mount the reflector M upon the back P in such a
manner that it slides into or is supported by the ears m³, m³ & mª by which it can
readily be removed and this reflector I prefer to face with glass N or otherwise to
form it of glass with a silvered back.
In the case of the bell reflector R shown by Figures 10 and 11 I provide a
facing S of glass which prevents the reflector from becoming tarnished or I may
silver or otherwise prepare the back of the glass S so that it may form the reflector
itself and this bell reflector may be carried back through the whole depth of the
lamp as shown by T Figure 12 with apertures t¹ and for the current & com-
bination of the flame in which case it may be a metal reflector. The lining 8 may
be fluted so as to give an increased surface for reflection and may be varied in
shape to meet the various requirements to be met. with,
I may use any one of these my said improvements either separately or combined
and I may vary my improvements herein first described by putting the hinge a³ ut
the junction a in which case A' would consist of the top front & side while the
part A would consist of the bottom back & reverse side.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
1 claim is :-
1st. The improvements in & relating to cycle lamps & in the manufacture of
the same substantially as berein set forth and shown upon the accompanying
drawings,
2nd. A cycle lamp consisting of two parts A' and A² hinged together substantially
as herein set forth and shown.
3rd. In cycle lamps the detachable glass reflector M substantially as berein
set forth & shown.
4th. In cycle lamps the detachable glass reflector M substantially as & for the
purpose herein described.
5th. In cycle lamps the glass bell lining S substantially as and for the purpose
herein set forth & shown,
6th. In cycle lamps the continuous reflector T substantially as & for the purpose
herein set forth & shown.
Dated this 27th day of February 1895.
