PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Lamps.
I, Joux Estox of 23 Woodhouse Lane, Wigan in the County of Lancaster,
Under Manager, do hereby declare the nature of this invention to be as follows:-
When a lamp such as a miner's lamp is carried in the hand the motion of the
body in walking and communicated to the lamp is very apt to extinguish the flame
unless the lamp is held very steadily in walking over rough ground, as for example
in a mine. It is however very diflicult to carry the lamp very steadily and the
flame is consequently very liable to be extinguished.
My invention is designed to prevent or greatly reduce the chances of the lamp
being extinguished.
In carrying my invention into effect I provide a device having a spring or elastic
cushion in the top of the lamp to which the handle, whereby the lamp is carried,
may be attached.
This device preferably comprises a spindle passing through the top of the lamp
and having a washer at the bottom, between which and the roof of the lamp is a
spring or elastic cushion.
When the handle is attached to the top of this spindle the weight of the lamp is
borne by the spring and the latter absorbs any sudden shock or jar and the danger
of extinguishing the flame is thereby greatly reduced or altogether obviated.

Improvements in or appertaining to Lamps.
1, JOHN EXION of 23 Woodhouse Lane, Wigan in the County of Lancaster,
Under Manager, 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:-
When a lamp such as a miner's lamp is carried in the hand, the motion of the
body in walking over rough ground, as for example in a mine, is very liable to
extinguish the flame, unless the lamp is held very steadily. It is however very
difficult to carry the lamp very steadily and the result is that the flame is very liable
to be extinguished.
My invention is designed to absorb the vibration and thereby prevent or greatly
reduce the chances of the lamp being extinguished. The invention consists
broadly in the application of a spring or elastic cushion to the top of the lamp and
to which a handle may be attached.
In describing the invention, reference may be had to the accompanying drawings,
in which
Figure is a front elevation of a miner's lamp with my spring device applied
thereto;
Figure 2 an enlarged view of the device:
Figure 3 a sectional elevation of a slight modification;
Figure 4 an elevation of an upper part of a lamp having a further slightly modified
form of my device applied thereto;
Figure 5 an enlarged view of the said modified device.
Referring to Figures 1 and 2, A is a spindle, B the bracket for the hook b for

page_text: hooking into the eye of the lamp, and an eye to which a handle may be attached.
The spindle A has a washer a at the bottom, between which and the top of the
bracket B is a spring Cor elastic cushion adapted to absorb the vibration resulting
from carrying the lamp in the hand, or when it is hung on a wagon travelling over
rough roads or otherwise.
In Figure 3, the spring C and all but the eye of the spindle, A, are boxed in
by the casing B, to which the hook is attached.
In Figures 4 and 5, the spindle A passes through the top of the lamp and
has a washer a at the bottom between which and the roof of the lamp is the
spring C.
When the handle is attached to the top of this spindle, the weight of the lamp
is borne by the spring, and the latter absorbs any sudden shock or jar; and
the danger of extinguishing the flame is thereby greatly reduced or altogether
obviated.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
clain is: :-
1. In a hand lamp, the application of a spring between the handle and the top
or underneath the top of the lamp, whereby the vibration resulting from carrying
the lamp in the hand or when hung on a wagon or otherwise is absorbed or
deadened.
2. In combination with a hand lamp, the herein described devices for absorbing
the vibration resulting from carrying the lamp in the hand, each taken as a whole,
whereby the liability of the flame being extinguished is greatly reduced or
prevented.
