PROVISIONAL SPECIFICATION.
Improvements in Metallic Supports for the Workings of Mines and
other purposes.
I, EUSTACHE AUGUSTE CRESSON, of 18 Rue Jean-Jacques Rousseau, Paris, in
the Empire of France, Engineer, do hereby declare the nature of my invention
to be as follows:-
My invention relates to metallic supports for the workings of mines and other
purposes.
It is generally known that the supports for vaults or tunnels, for example, require
a considerable amount of material, the transport and labour connected therewith
entailing a large expense.
Moreover the putting up and pulling down, or the taking down of the centres
from arches, cannot be done rapidly, and entails the employment of a certain
number of special workmen.
My invention consists in an improved system of apparatus, which remedies
these inconveniences, and permits the most inexperienced men, to erect or take
down the supports with great facility and dispatch.
I carry out my invention by arranging a series of metallic casings, which can be
carried or transported where circumstances demand.
These casings are formed of a number of corrugated, arched, metal plates, or
panels, which are preferably coated with zinc and arranged together in pairs.
The lower extremity of each of the panels has an angle iron attached to it,
preferably by rivets, one side of which angle iron is provided with holes, for nailing

Improvements in Metallic Supports for the Workings of Mines and
other purposes.
1, EUSTACHE AUGUSTE CRESSON, of 18 Rue Jean-Jacques Rousseau, Paris,.
in the Empire of France, Engineer, do hereby declare the nature of my 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 relates to metallic supports for the workings of mines and other
purposes.
It is generally known that the supports for vaults or tunnels for example require
a considerable amount of material, the transport and labour connected therewith
entailing a large expense.
Moreover the putting up & pulling down or the taking down of the centres from
arches, cannot be done rapidly and entails the employment of a certain number of
special workmen. My invention consists in an improved system of apparatus which
remedies these inconveniences and permits the most inexperienced men, to erect or
take down the supports with great facility and despatch.
I carry out my invention by arranging a series of metallic casings which can be
carried or transported where circumstances demand.
In order that
my invention may be the better understood I will now proceed to
describe the same in relation to the drawings hereunto annexed, reference being
had to the letters and figures marked thereon. Like letters refer to like parts in
the various figures.
Fig. 1 is a transverse section of my apparatus for use in subterranean workings.
Fig. 2 is a side view of a portion of my support.
Fig. 3 is a plan of the same.
Fig. 4 shows in plan and side elevation the details of a cramp.
Fig. 5 shows a front and side view and a sectional view on the line 1 and 2 of the
same cramp furnished with a key.
Fig. 6 shows the mode of assembling and fastening the upper part of the
metallic casings.
Fig. 7 shows the mode of fixing the foot of the casings by spikes shown in
Figure 8.
Fig. 9 shows a longitudinal section of the apparatus on the line 3-4 Fig. 1.
Fig. 10 shows the same part in plan.
Fig. 11 shows a longitudinal section following the line 5-6 Figure 1.
Fig. 12 shows an outside view of the foot of the casing.
Fig. 13 shows in section the mode of the upper parts of a casing before being
fastened together.
These casings are formed of a number of corrugated, arched, metal plates or
panels, which are preferably coated with zinc and arranged together in pairs.
The lower extremity of each of the panels a has an angle iron b attached to it,
preferably by rivets, one side of which angle iron is provided with holes, for
nailing or spiking it with spikes c to longitudinal sleepers d placed in the heading
or road e as shown in Figures 1 and 7 more particularly. At the upper part of
each panel a, a bar fis arranged longitudinally, and is preferably fixed thereto by
rivets. The bar f of one panel is furnished with spurs or projections 9 which are
adapted to engage with holes or openings g¹ arranged in the bar f of the corre-
sponding panel. Several openings or notches are conveniently disposed in the
sides or flanges of the said longitudinal bars f to receive a cramp h having a key i
provided at its end with an arm which acts by pressure on the internal face of the
. said longitudinal bar to produce the bringing together and the fixing of the upper
parts of the panels as shown in Figure 6.

page_text: The fixing together of the sections longitudinally is effected by the engagement
of the last corrugations of each section with those of the next section.
It must be understood that I do not limit myself to the employment of my
apparatus to vaults or tunnels as it is equally applicable for covering houses,
stables, etc. and as tubes for the encasement of water, air, or gas pipes, electrical
conductors etc.
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
claim is :-
The construction and arrangement of metallic supports for the workings of mines
and other similar works substantially as described and illustrated in the accompanying
drawings.
