PROVISIONAL SPECIFICATION.
Improvements in Rock Drilling and Boring Machines.
I, JOSEF SCHNEIDER of Triebschitz, Bohemia in the Empire of Austro-
Hungary, Miner, do hereby declare the nature of this invention to be as follows:-
The machine is mounted in an iron frame or carriage supported by wheels
adapted to run on rails.
The drilling mechanism consists of preferably round smooth iron rods provided
at the top each with a square pin or extension and below with a shoulder and a
conical socket say 6 c.m. in length and having a swelling of say 5 m.m. at the lower
part. The drilling mechanism is carried by a toothed wheel, upon the square end
of whose shaft is fitted the before mentioned conical socket while its lower tapering
portion rests in a bearing or plate. This plate is capable of being moved or
adjusted upwards and downwards by means of screw spindles supported by the
walls of the frame or, if required, by other suitable means. These screw spindles
along with the bevel-wheels secured thereon receive motion from the driving shaft
preferably through the medium of the graduated pulleys a second shaft, toothed
wheels gearing this shaft with another or third shaft on which bevel wheels are
firmly secured or keyed.
To enable the drilling shafts or spindles to rotate, in addition to their up-and-
down motion each of the wheels supporting or operating the drilling mechanism
engages with a ribbed or toothed cylinder or roller provided with a bevel wheel at
the lower part which cylinder or roller is operated from a bevel wheel mounted on
the "second" shaft and conveying the rotary motion to the roller.
The shoulder on each of the drilling-rods allows of the first rod measuring
several metres in height being supported "by means of catches when the drill-
operating gear is being lowered for placing in position, a fresh rod, or while a
superfluous rod is being removed.

COMPLETE SPECIFICATION.
Improvements in Rock Drilling and Boring Machines.
I, JOSEF SCHNEIDER of Triebschitz, Bohemia, in the Empire of Austro-
Hungary, Miner, 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 machine is shown in the accompanying drawings,
Figure 1 being a sectional front view,
Figure 2 a section on line x x Figure 1.
Figure 3 a section on line y y, Figure 1.
The machine is mounted in an iron frame or carriage A supported by wheels b
adapted to run on rails a.
The drilling mechanism consists of preferably round smooth iron rods B provided
at the top each with a square pin or extension e and below with a shoulder and a
conical socket d, say 6 centimetres in length and having a swelling of say 5 m.m. at
the lower part. The drilling mechanism is carried by a toothed wheel Z the
upon
square end of whose shaft e is fitted the before mentioned conical socket d, while
its lower tapering portion f rests in a bearing or plate C. This plate is capable of
Paine B1

page_text: being moved or adjusted upwards and downwards by means of screw spindles h h
supported by the walls of the frame or, if required, by the plate g. These screw
spindles along with the bevel-wheels ' secured thereon receive motion from the
driving shaft D preferably through the medium of the graduated pulleys SS' a second
shaft w, toothed wheels gearing this shaft with another or third shaft on which
bevel wheels are firmly secured or keyed on the shaft w¹.
To enable the drilling shafts or spindles to rotate, in addition to their up-and-
down motion, each of the wheels Z supporting or operating the drilling mechanism
engages with a ribbed or toothed cylinder or roller E provided with a bevel wheel m
at the lower part, which cylinder or roller is operated from a bevel wheel n mounted
on the shaft to and conveying the rotary motion to the roller.
For the sake of greater clearness only one roller E is shown in Figure 1 the
other being removed.
The shoulder d on each of the drilling rods allows of the first rod, measuring
several metres in height, being supported by means of catches arms or brackets p
when the drill operating gear is being lowered for placing in position a fresh rod
or while a superfluous rod is being removed.
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. A boring or drilling machine characterized by rods B secured to toothed
wheels Z which are moved up and down by the spindles carrying the said toothed
wheels Z and supported by the bearing-plate C, while they are rotated by the
engagement of the said wheels with the grooved revolving cylinders E the plate C
being adjustable by the screw-spindles à substantially as described and illustrated
in the accompanying drawing.
2. In a machine such as described in Claim 1 the transmission of motion to the
screw-spindles from the driving-shaft w which by means of the toothed wheels i
operates the shaft w¹ and the bevel-wheel k which is in gear with a similar bevel-
wheel rigidly secured to one of the said screw-spindles while the grooved or
ribbed cylinder E is operated also from the said driving-shaft w but through the
medium of the bevel-gearing n and m substantially as described and illustrated in
the accompanying drawing.
3. The combination and arrangement of parts constituting the complete machine
substantially as described and illustrated in the accompanying drawing.
