GEORGE EDWARD VAUGHAN, of 57 Chancery Lane, in the County of Middlesex,
Patent Agent, IMPROVEMENTS IN THE METHOD OF, AND APPARATUS FOR, BORING
AND DRILLING HOLES IN COAL AND LIGNITE," A communication to me from
abroad by Josef Werndl, Managing Director of the Oesterreichische, Waffenfabriks-
Gesellschaft, of Steyr, in the Empire of Austria,
This Invention consists in improvements in the method of, and apparatus for,
boring and drilling holes in coal and lignite and is hereinafter described with
reference to the accompanying Drawings.
The same letters of reference indicate like parts in all the Figures. A is the
main column consisting of a steel tube. At the ends of the said column are inserted
two clutches a. for fixing the same. One of the said clutches is provided with a
screw b. by means of which the clutch may be raised or lowered.
On the column A. is fixed the rack c. and on the side of the said rack are formed
notches. On the column A. is arranged the bracket piece B. so as to be capable of
moving up and down, such bracket piece being held in position by a set screw.
The said bracket B. carries the strap or rope pulley provided for transmitting
motion to the boring tool, it also carries the guide for such tool.
In Figures I., 2. and 3. various forms of arrangement of the bracket B. are
represented.
The second guide column is shown at C. Figure 1.
The bracket B. has a guide piece e. at the posterior flange Z. of which is a
steering wheel f. the teeth of which gear into the rack c. of the column A. by which

page_text: arrangement the bracket B. can be moved up and down the said column by means
of a winch handle fitted to the spindle g. of the steering wheel. In moving the
bracket, the collar 1. slides on the guide column C.
The guide D. of the bore socket E. is cast on the right end of the bracket B. The
socket E. has at its anterior end a coned wheel F. and the bore rod G. passes
through the socket. The bore rod has a longitudinal groove l. into which the
pivot m., fixed to the mouth of the socket, gears, when the bore socket, and with it
the borer, revolve the latter can be moved forward and backward.
The bracket piece B. has two arms n. n¹. in which is bushed the driving shaft o.
which carries at one end the rope pulley 8. and at the other end the coned wheel H.
by means of which the bore socket is revolved.
In the apparatus herein before described the motor is situated at the back of the
operator.
In the arrangement of the apparatus shown in Figure 2. the bracket consists of
two arms placed at right angles to each other, the second guide column C. being
dispensed with.
One of the arms of the bracket consists of the guide D. for the bore socket E, to
which the cheek e. for the column A. is attached. The flange Z. with the steering
wheel is fixed to the face of the cheek e.
.The second arm w. of the bracket B. carries the bush v. for the rope pulley 8.
with its driving wheel r., the bush v. for the wheel 1. transmitting the motion of
the rope pulley, and the bush 11 of the of the driving wheel R. of the bore socket.
i In this arrangement of apparatus the motor is in position at the side of tho
operator.
In Figure 3. a third arrangement of the bracket B. is shown.
The guide cheek c. is attached to the left side of the guide D. of the bore
socket E.
·
The arm n. fitted to the lower side of the guide, upon which it is movable.
The driving shaft o. may be moved in the bush x. and carries, at one end, the rope
pulley 8., and, on the other end the driving pinion H. which gears into the coned
wheel of the bore socket, and imparts motion to the latter.
In order to fix the bracket B. in varying positions during working, notches d.
are cut in the rack c. The spring catch y. (as shown in Figures 3 and 5.) gears
into the said notches. In raising the bracket by means of the wheel, the spring
catch y. is automatically moved from one notch to another.
If the bracket is to be lowered, the said catch is pulled back by hand..
The application of the apparatus herein before described to the boring or drilling
of holes in coal or lignite is effected as follows:-
The apparatus having been placed at the breast of a seam, a number of holes are
bored to the right or left perpendicularly from below upwards and in such a manner
that the borer at each hole advances.somewhat in front of the preceding hole. A
cutting is made thereby, as shown in Figure 4. of any desired width and depth,
according to the diameter of the borer and the length of the bore rod. As soon as
the two side cuttings have been made the apparatus is reversed for the horizontal
cutting, when the operator proceeds as above described..
The transmission of the motive power, instead of being effected by a rope or
strap, is, in some cases, effected by mounting a small dynamo machine on the
bracket B. in place of the pulleys and sending through it an electric current
generated outside the heading by a dynamo machine.

the said George Edward Vaughan in the Patent Office on the 3rd January
1884.
GEORGE EDWARD VAUGHAN, of 57 Chancery Lane, in the County of Middlesex,
Patent Agent, "IMPROVEMENTS IN THE METHOD OF, AND APPARATUS FOR, BORING
AND DRILLING HOLES IN COAL AND LIGNITE." A communication to me from
abroad by Josef Werndl, Managing Director of the Oesterreichische Waffenfabriks-
Gesellschaft, of Steyr, in the Empire of Austria,
The said Invention consists in improvements in the method of, and apparatus
for, boring and drilling holes in coal and lignite and is hereinafter described with
reference to the accompanying drawings.
The same letters of reference indicate like parts in all the Figures. A. is the
main column 'consisting of a steel tube. At the ends of the said column are inserted
two clutches a. for fixing the same. One of the said clutches is provided. with a
screw b. by means of which the clutch may be raised or lowered.
On the column A. is fixed the rack c. and on the side of the said rack are formed
notches. On the said column is arranged the bracket piece B. so as to be capable
of moving up and down, such bracket piece being held in position by a set screw.
The said bracket B. carries the strap or rope pulley provided for transmitting
motion to the boring tool; it also carries the guide for such tool.
.
In Figures 1., 2. and 3. various forms of arrangement of the bracket B. are
represented.
The second guide column is shown at C. Figure 1.
The bracket B. has a guide piece e. at the posterior flange Z. of which is a
steering wheef f. the teeth of which gear into the rack c. of the column A. by which
arrangement the bracket B. can be moved up and down the said column by means
of a winch handle fitted to the spindle g. of the steering wheel. In moving the
bracket the collar h. slides on the guide column C.
The guide D. of the bore socket E. is cast on the right end of the bracket B..
The socket E. has at its anterior end a coned wheel F. and the bore rod G. passes
through the socket. The bore rod has a longitudinal groove l. into which the
pivot m., fixed to the mouth of the socket, gears. When the bore socket and, with
it, the borer revolve the latter can be moved forward and backward.
The bracket piece B. has two arms n. n¹. in which is bushed the driving shaft o.
which carries at one end the rope pulley s. and at the other end the coned wheel H.
by means of which the bore socket is revolved.
In the apparatus herein before described the motor is situated at the back of the
operator.
In the arrangement of the apparatus shown in Figure 2. the bracket consists of
two arms placed at. right angles to each other, the second guide column C. being
dispensed with.
One of the arms of the bracket consists of the guide D. for the bore socket E. to
which the cheek e. for the column A. is attached. The flange Z. with the steering
wheel is fixed to the face of the cheek e.
The second arm w. of the bracket B. carries the bush v. for the rope pulley 8.
with its driving wheel r. the bush v. for the wheel 1. transmitting the motion of
the rope pulley, and the bush v¹, of the driving wheel R. of the bore socket.

The guide cheek e. is attached to the left side of the guide D. of the bore
socket E.
The arm n. is fitted to the lower side of the guide, upon which it is moveable.
The driving shaft o. may be moved in the bush x., and carries, at one end, the rope
pulleys, and, on the other end the driving pinion H. which gears into the coned
wheel of the bore socket, and imparts motion to the latter.
In order to fix the bracket B. in varying positions during working. notches d. are
cut in the rack c. The spring catchy. (as shown in Figures 3. and 5.) gears into
the said notches. In raising the bracket by means of the wheel, the spring catch y.
is automatically moved from one notch to another.
"
If the bracket is to be lowered, the said catch is pulled back by hand.
The application of the apparatus hereinbefore described to the boring or drilling
of holes in coal or lignite is effected as follows:-
3.
The apparatus having been placed at the breast of a seam, a number of holes are
bored to the right or left perpendicularly from below upwards and in such a
manner that the borer at each hole advances somewhat in front of the preceding
hole. A cutting is made thereby, as shown in Figure 4. of any desired width and
depth, according to the diameter of the borer and the length of the bore rod. As
soon as the two side cuttings have been made, the apparatus is reversed for the
horizontal cutting, when the operator proceeds as above described.
T
The transmission of the motive power, instead of being effected by a rope or
strap, may be effected by mounting a small dynamo machine on the bracket B. in
place of the pulley s., and sending through it an electric current generated outside
the beading by a dynamo-electric machine.
Having thus described and ascertained the nature of the said Invention and the
manner in which the same is to be performed I would observe in conclusion that
what, I consider novel and original and therefore claim as constituting the invention
secured to me by the said herein before in part recited Letters Patent, is:-
First. The improvements in the construction of boring machines, consisting of a
hollow column with a moveable bracket arranged thereon, substantially as herein-
before set forth and described and shown in Figures 1., 2. and 3. of the accompanying
drawings.
-
And Secondly. The application of boring machines, constructed as hereinbefore
described, in such a manner that the bore holes are combined to a cutting, substan-
tially as herein before set forth, and described and illustrated at Figure 4. of the
accompanying drawings.
In witness whereof I the said George Edward Vaughan have hereunto set my
hand and seal this, second day of January in the year of our Lord One thousand
eight hundred and eighty four.
