COMPLETE SPECIFICATION.
Improvements in Igniting Devices for Miners' and other Lamps.
1, HEINRICH FREISE, of Hamme Bochum, in the Empire of Germany,
Engineer, 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:-
The present invention relates to a device for igniting miners lamps and consists
of the details of construction hereinafter set forth and particularly specified
in the claims.
In order to render the present Specification more easily intelligible reference is
had to the accompanying drawing in which similar letters of reference dcuote
sunlar parts throughout the several views:
Figure 1 is a vertical longitudinal section through the device,
Figure 2 is an end elevation of the device,
Figures 3 and 4 are similar section and elevation of a modified form of the
device,
Figure 5 is a partial transverse section through a modified form of the device,
Figure 6 a partial longitudinal section of Figuro 5,
Figure 7 a detail of the operating device for the igniting band,
Figure 8 a side elevation of the body of a miners lamp and
Figure 9 a plan view of Figure 8.
Referring to Figures 1 and 2-a is the body of the device and c the igniting
band having explosive pellets & thereon and mounted in the casing a to revolve in
the usual manner. The rear wall of the casing a 18 formed by a spring bent to
incline towards the front wall at f and possessing at this portion two horizontal
notches and e. dis the rod by means of which the ignition is effected and which
is provided with spikes 9 to engage and move forward the band of explosive
pellets b. The rod d 18 adapted to slide vertically in the body of the miners lamp
to which the device is attached, said rod being provided with an upper horizontal
bar adapted to engage in the notches e and k
The device operates in the following manner :-
On pushing the rod d upwards, the spikes 9 engage in the igniting baud and the
cross bar of the said rod simultaneously pushes back the inclined surface of
the spring f, so that the band will be raised. This is effected by the horizontal bar
of the said rod d pressing against the surface between the two notches e and k. As
soon as the bar reaches the second notch k, the band has been sufficiently advanced
to allow the next pellet to come under the part of the spring f. As the bar
reaches the notch, the spring slips off the same and the upper part i contacts
with the pellet lying thereunder, the latter is thereby ignited and being arranged in
close proximity to the wick of the lamp-as herein after described-ignites the
lamp, as will be easily understood.
In the device illustrated in Figures 3 and 4 the ignition is effected by drawing
the rod d downwards and for this purpose the spring f is bent in the opposite
duection so that on pulling the same downwards the hammer m will first be removed
from the igniting band which is transported by the spikes g of the rod d and then
on the cross bat of the said rod entoring the notch e the spring is released and
strikes the explosive pellet thereunder igniting the lamp in the manner previously
described. In this case the explosive pellet band is guided over a suitable bridge
arranged under the hammer m.

In Figures 5 to 7 a further modification is illustrated according to which the
rod p is mounted to slide and also to rotate in the body or well of the lamp The
spring o having suitable teeth 18 spring pressed against the upper part of the casing
and the igniting band is moved upwards by means of the teeth y of the rod which
onerate through a slot of the casing to raise the band or ribbon. At the rear side
of the said 1od p is arranged a second tooth which is adapted to engage in a slot t
of the sleeve in which the wick of the lamp (Figures 8 and 9) is guided, on turning
the rod p, so that the tooth at the rear of the rod p may be employed to raise and
Lin the wick of the lamp when the rod is turned sound a certain angle. In
Figmes 8 and 9 the body of the lamp is represented by the letter u.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I doclare that what I
claim 18:
An guiting device for mining and other lamps having a spung hammer to
ignite the pellets, Faid hammer being operated by a sliding rod having spikes
to transport the band containing the explosive pellets and being arranged in the
lamp close to the wick of the same substantially as described.
2. In combination with the device covered in Claim 1, the arrangement of a
hammer and means to operate the same at the downward stroke of the rod the
igniting band being guided under the hammer in the manner and for the purpose
substantially as described.
3 A modification of the device covered in Claims 1 and 2 consisting of a spring
pressed tooth 1od to engage the explosive pellet and guite the same, and a rod to
operate the band to which the pellets are attached, said od having teeth to engage
the pellet band and a tooth at the opposite side to engage the wick of the lamp
substantially as described, said rod being mounted to rotate and also to slide in the
body of the lamp.
