HARRY LUCAS, The "Tom Bowling" Lamp Works, Little King Street, Birmingham,
Lamp Manufacturer, and WILLIAM PRESTLETON, 19 Church Vale Handsworth, Tool
Maker, do hereby declare the nature of this invention to be as follows:-
--
Firstly. Our object is to fix removable reflectors inside lamps for velocipedes and
other purposes by a less troublesome method than the existing ones of screwing the
reflector or fitting it on a rim to the back of the lamp. We make the reflector to
cover or nearly cover the back of the lamp and it is held at the top by slipping
it into a clip or clips or into a groove, and at the bottom it is held by being pressed
to the back of the lamp by a spring or springs. preferably by the same spring
which is used on the reservoir to prevent its shaking or rattling in the lamp, or the
reservoir itself may be made to press against the reflector so that the act of closing
the lamp door causes the reservoir and the reflector to be held firmly in their
respective positions. We attach a handle to the bottom of the reflector for the greater
convenience of getting it in and out of the lamp.
Secondly. We make an improved anti-vibrating spring back or attachment for
lamps for velocipedes and other vehicles so as to dispense with the vertical coiled
spring now used to support the lamp in anti-vibrating arrangements. We prefer to
use one arm, or a pair of arms, near the top of the back of the lamp and another near
the bottom, as is usual to produce a vertical movement of the lamp, but a single arm
or pair of arms fixed to the middle of the back of the lamp may be used, and we make
the arms to form, combine or contain the necessary spring to give an easy movement
to the lamp substantially in the manner we now describe. We prefer to make the
arms hinged or jointed to the lamp and to the socket plate with a coiled spring
enclosed in one or more of the hinges and fixed so as to give the necessary spring to
the arm, or the arms may be hinged at one end and coiled or made to form a spring
at the other end, or, again, the arms may be coiled or made to form a spring at
each end.

page_text: Thirdly. We make an improvement in burners for lamps for velocipedes and other
vehicles by adopting a simple method of preventing the wick dropping into the socket.
We put a self-acting clip on the spindle or winder and inside the burner case to hold
the spindle firm enough to prevent its turning by any jolting the lamp may receive
but to allow of its being turned by the fingers when required.

We, HARRY LUCAS, of the "Tom Bowling" Lampworks, Little King Street,
Birmingham, in the County of Staffordshire Lamp Manufacturer, and WILLIAM
PRESTLETON, of 19 Church Vale, Handsworth in the County of Staffordshire, 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:-
Our invention relates to first to a method of fixing the reflectors inside lamps,
secondly, to an anti-vibrating attachment for supporting the lamp, and thirdly, to an
improvement in the burners of lamps, and it has for its objects, First, facilitating the
removal and replacement of the reflector, Secondly, simplifying and increasing the
efficiency of the anti-vibrating attachment, and thirdly, preventing the wick from
dropping in the socket of the burner.
We attain these objects in the manner illustrated in the accompanying drawing in
which Figure 1. is a view in sectional elevation of a lamp fitted with our improve-
ments. Figure 2. is a view in front elevation of the reflector. Figure 3. is a view in
plan of the anti-vibrating attachment, Figures 4. and 5. and Figures 6. and 7. are
views in elevation and plan respectively of modifications of the anti-vibrating attach-
ment, and Figure 8. is a view in front elevation of a device for preventing the wick
dropping in the socket of the lamp.
Throughout these views similar parts are marked with like letters of reference.
Referring to the first part of our invention which is illustrated by Figures 1. and 2.
of the accompanying drawing. The reflector A. instead of being screwed into, or
fitting on, a rim in the back of the lamp is made of a shape to coincide with the

page_text: whole surface of the back of the lamp, or nearly, so and is adapted to slip under
a clip or clips a. fixed on the back of the lamp at the top thereof, and is provided
at its bottom with a suitable handle a preferably formed of wire bent to such a
shape that when it is turned back it acts as a spring. The reflector after being placed
in position is kept there and prevented from shaking or rattling by the pressure of
the oil reservoir X., the pressure on the oil reservoir being caused and maintained by
the closing of the door Y., of the lamp in the usual manner. We sometimes usc an
independent spring to maintain the reflector in position fixed either on the lamp or on
the reservoir.
We
Referring to the second part of our invention which is illustrated by Figures 1. 3.
4. 5. 6. and 7. of the accompanying drawing. We make the anti-vibrating attach-
ment in the manner already known and illustrated by Figure 1. but instead of
controlling the motion of the lamp by a vertical coiled spring we use a transverse
coiled spring enclosed in one or more of the arms or hinge attachments.
connect the socket plate Z. with the body of the lamp by a pair of flat arms B. B.
pivotted by pins etc. passing through rubber bushes at three of the joints, the
other joint containing the transverse coiled spring b. fixed at one end to the pin b¹ by
the screw 63 the other end passing out through a slot in the eye of the arm and fixer
thereto by the screw b' and plate 6. We sometimes make the spring and arm in one pieces
as illustrated by Figures 4. and 5. We prefer to make the coiled spring bifurcated as
illustrated by Figures 3. 5. and 7. to facilitate fixing the inner end of it to the pin b'.
When the spring and arm are made in one piece a plate is used sufficiently thick to
make a rigid arm, and the necessary elasticity is then obtained by bifurcation of the
coiled spring. If desired a spring may be so formed at both ends of the arms.
Another modification consists in mounting the transverse coiled spring or springs on
the socket plate or body of the lamp and using two pairs of " gate armis B. B. as
illustrated by Figures 6. and 7. of the accompanying drawings. It will be obvious
that instead of using two arms or pairs of arms a single arm or pair of arms may be
used if fitted to the centre of the lamp, and provided with a spring at each end.
Referring to the third part of our invention which is illustrated by Figures 1.
and 8. of the accompanying drawing. We prevent the wick dropping in the socket
of the burner by mounting a frictional spring c. on the winder spindle C. preferably
between the two cogs c c as illustrated. This frictional spring consists of a piece of
sheet steel bent to fit tightly round the spindle C. and form a tail which fits inside the
burner case. and bears against the side thereof or against the socket, according in
which direction it is turned, and so gives sufficient frictional resistance to the rotation
of the winder spindle to prevent its turning by an jolting, the lamp may receive, but
will yet allow of it being turned by the fingers when desired.
It will be obvious that the first and third parts of our invention can be applied to
lamps of other type than those used for Velocipedes.
We are aware that the arms of anti-vibrating attachments have already been
controlled by springs surrounding or mounted on the pivots of such arms, and also
that springs have also been used to give a frictional resistance to the rotation of
the winder spindles of lamps, and we therefore do not broadly claim such devices,
but 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 :-
1st. Fitting the reflector to the inside of a lamp in manner, and for the purpose,
specifically as herein set forth.
2nd. In a lamp adapting the reflector to fit the entire back of the lamp and to be
retained in position by the pressure of the of the door of the lamp, through the oil
