Improvements in Devices or Means for Depicting or Displaying a
Series of Representations, Views, Plans, or Drawings of Mines,
Underground Works, Earth-works, and the like.
I, AUGUSTUS WYNNE STODDART, of Johannesburg, South African Republic,
General Manager of The Meyer and Charlton Gold Mining Company, Limited,
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:-
This invention relates to devices or means for depicting or displaying a series or
number of separate and distinct representations, views, plans or drawings of mines,
underground works, earth-works and the like, whereby the surface and every level
or underground working of say a mining property may all be seen at one and the
same time in their true relative positions, and also each shaft, building or other
erection, claim, boundary mark or beacon, in conjunction with each distinct.
"level with its shafts, drives, winzes, stopes, upraises, cross-cuts, and faults or
dykes.
"
It is designed with the object of so constructing the device or appliance that
dimensions, angles, quantities and such like information may be obtained therefrom
without extensive calculation.
It consists essentially of a device comprising in its construction a series of sheets
or plates of glass arranged one above or over another on which is painted, drawn or
otherwise depicted a representation of the desired particulars or details of each
section or level of the mine underground or earth-work in combination with one,
two or more plates on which dimension lines or the like are produced to the same
scale as the particulars or details of each level have been drawn or otherwise
produced on the sheets representing the several levels, and one or more preferably
vertical plates on which dimension lines, angles and other particulars are suitably
inscribed.
1
The invention will be fully described with reference to the accompanying sheet.
of drawings in which
Fig. 1, is an end elevation of a device or appliance constructed in accordance
with my invention.
Fig. 2, is a plan of same.
The
The device consists of a framework A preferably comprising the base a and the
two vertical sides a a² of wood, metal or other suitable material. The vertical
sides a a² are formed with horizontal grooves or recesses B on the inside, which
grooves may be formed at any regular or irregular distances as may be desired, say
such as may represent to a given or predetermined scale the exact distances
between the several levels of the mine or the like. At one end the vertical
sides a a are preferably also formed with vertical grooves or recesses C.
other end of the vertical sides is preferably left open to permit of the ready
insertion or withdrawal of the several sheets or plates of glass supported in the
horizontal grooves B. It will be evident however that the other extremity of the
vertical sides may be formed with grooves corresponding to the grooves C to permit
of the insertion of one or more vertical plates to completely enclose the device and
to prevent the entrance of dust.
The several plates or sheets of glass b b¹ b³ b³ 64 65 each represent a separate and

page_text: distinct level of the mine or the like, and the distance between each sheet is to a
given scale with the distances between the levels of the same. On the surface of the
sheet is drawn or otherwise depicted in coloured inks or paints a ground or
surface plan of the mine, or the like to a given. scale, shewing, the boundary lines c,
the outcrop of reef c¹, position of shafts, buildings or any other similar erections.
On the underside of this sheet lines d are drawn dividing the plate up into
squares representing to the same scale feet, yards, fathoms or any other desired!
standard of measurement. The property is shewn divided by the lines e into
the claim areas. Instead of marking the sheet with the lines representing the:
several dimensions, threads, wires or the like might be employed in substitution
therefor.
The sheets 12 13 14 1³ each represent a separate and distinct level of the mine
and upon each is drawn or otherwise depicted an outline boundary of the property
and within the same the drives, shafts, winzes, stopes, upraises, cross-cuts, faults.
etcetera to the given scale, and correct as regards position in relation to the
boundary line. On each of these sheets or plates is also preferably indicated
the vertical or "level" depth and where a shaft cuts or penetrates a level the
"incline" depth at that point also marked thereon.
The plate or sheet is marked with lines dividing the plate into a series of
squares representing to the given scale feet, yards, fathoms or other standard of
measurement in a similar manner to the underside of the uppermost plate b and has
also indicated or marked upon it the boundary lines of the property divided into its
several claim areas.
A covering plate or sheet D preferably of a stronger or thicker glass is provided
to act as a protection for the plate and the several other somewhat lighter
plates.
At one end a vertical plate or sheet E is provided on which is depicted dimension
lines d'angle or inclination lines d' and the dip or inclination of the shafts d³
together with cross sections c² of the different reefs and any other desired particulars
or information. It will be evident that the other or open end of the device may be
provided with a vertical plate similar to E on which may be inscribed similar or
any other desired particulars as may be found convenient.
It will be obvious that by using the sheets upon which the dimensions are
marked or indicated as 66
sights" between which the several sheets representing
the levels lie, the length of any level or drive, the dimension of any stope, and
approximately the amount of ore contained therein, and the probable amount of
ore in any unworked level, may be obtained at a glance and without necessitating
extensive calculation.
If desired the shafts, rises, winzes or other connections between the various
levels may be more clearly shown or indicated by attaching pieces of wood, cork,
plaster, or other suitable material to the surface of the piates of glass, and in a
similar manner the sheet of glass representing the "surface" plan may have affixed
to it suitably shaped pieces of wood, cork or other material cut or formed to
represent buildings; shafts, works and the like.
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 :-
1. In devices or
appliances for depicting or displaying a series of representations,
views, plans or drawings of mines, underground works, earth-works and the like,
the employment of a number of sheets of glass on which is drawn, painted or
otherwise depicted particulars of the several levels or sections in combination with
one, two or more suitably placed sheets on which are marked lines to represent to
the given scale any desired standard of measurement, substantially as described
and shewn in the accompanying drawings.
2. In devices for depicting a series of views or plans of mines and the like
constructed with one, two or more vertical sheets or plates on which are marked

page_text: lines to represent to a given scale any desired unit or standard of measurement in.
combination with a number or series of angle or inclination lines, substantially as.
described and shewn.
3. In devices for depicting a series of plans of mines or the like constructed.
with a number of sheets of glass on which are drawn, painted or otherwise
represented particulars of the several levels or sections, the employment of one,.
two or more sheets on which lines are marked to represent to a given scale any
desired unit or standard of measurement in combination with one, two or more-
vertical sheets or plates provided with dimension lines and a series of angle lines,.
substantially as described and shewn.
