Patents, with their Petition, on the 5th November 1858..
We; Louis SCHWARTZKORF and FERDINAND CARL PHILIPPSON, both of
Berlin, do hereby declare the nature of the Invention for "IMPROVEMENTS

page_text: within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Ferdinand Carl Philippson, on behalf
of myself and of the said Louis Schwartzkopf, do hereby declare the nature of
the said Invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement
thereof, that is to say :-
:
This Invention has for its object improvements in machinery for boring
holes in rocks and minerals for blasting and other similar purposes. For this
purpose a beam or girder is mounted on a bed or carriage in such a manner
as to be capable of assuming an inclined position corresponding with the
direction in which it is desired that the hole should be bored. On the face of
the beam or girder a block is mounted which is capable of sliding upon it
from end to end; this block carries a cylinder to which steam, or it may be
compressed air is admitted by a suitable arrangement of valves, so as to cause
a piston, which the cylinder contains, to traverse continuously while the
machine is at work to and fro within the cylinder. At each motion of the
piston its rod strikes an instrument placed below it, and which carries a
cutting tool of an ordinary description, and the end of the tool is thus caused
to penetrate the rock or mineral. Between each stroke the tool holder is
lifted by springs or otherwise and is turned partly round by a ratchet apparatus
actuated by the piston in its to-and-fro movement; as the work progresses
the block is caused to slide on the beam or girder to keep the tool up to its
work.
And in order that our said Invention may be most fully understood and
readily carried into effect, we will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.
Figure is a front view, Figure 2 is a longitudinal section, and Figure 3
is a transverse section of a machine constructed according to our Invention.
a is a beam or girder, which it is preferred to make of a trough form, having
at its upper end a ball or globe a'. This beam or girder is connected with a
bed or carriage of any convenient construction by means of the two rings b
and b, the ring b being fixed to the carriage, and the ring b¹ jointed to the
ring on one side and drawn down towards it by the screw bolt be on the
other side, so as to nip the globe a', and securely hold the beam or girder a in
any position to which it may previously have been adjusted.
On the face of the beam or girder a sliding block is mounted, which

page_text: contains a steam or air cylinder c, and is held against the face of the beam or
girder by the V grooves d, d, on each side of the sliding block, which embraces
the inclined edges of the beam or girder a. The steam (or if the machine be
employed in a mine where the use of steam would be inconvenient, compressed
air may be substituted for steam) is conducted from the pipe e to the cylinder c
by the valve, which is actuated in the following manner:-The rod g of the
piston carries at its end the cross head g; this cross head is guided in its to-
and-fro movements by the standards h, h, fixed on the cylinder c, and carries an
incline g, which each time that the piston ascends as it arrives near the end of
its course, strikes against a friction pulley mounted on the arm f', which is fixed
on the stem of the valve f, and causes the valve and its stem to move partly
round. On the lower end of the stem is fixed the arm i which, when the
stem is moved as above mentioned is caught by the spring catch i, and is
during the downward stroke of the piston held in this position, that is to say,
so as to admit steam over the piston and allow that under the piston to escape
through the exhaust pipe; the steam pipe is marked e in the Drawing, the
exhaust pipe e¹, the steam passages in the valve which are open at both ends
for the admission of steam are marked f, f, and the exhaust passage which
is closed at the ends, and constantly covers the exhaust port and alternately
connects it with one and other of the two steam ports is marked f. When
the piston arrives at the end of its down stroke, the pin projecting from
the cross head g depresses the spring catch i, and allows the valve f to be
brought back by the spiral spring k to its original position, that is to say, so
as again to admit steam under the piston, and allow the steam above the
piston to escape. Each time that the piston. rod g' descends its end strikes on
the tool holder m into the lower end of which an ordinary boring tool n is
keyed, the tool holder when struck descends a short distance, sufficient space for
its motion being left between the ratchet wheel o fixed on it and the upper
surface of the guide p carried by the standards h, h, and in which guide the tool
holder m slides. When the piston rod rises the tool and tool holder are again
raised by the spring g, which is a steel ring of the form shewn; each time
also that the piston rises the boring too! is turned partly round, and this
is done by the arm r on the valve rod f, and the drivers which is jointed
to it, and enters the teeth of the ratchet wheel o, being pressed up to the
ratchet wheel by the spring t. As the boring progresses, it is necessary
that the boring tool should travel forwards, and this is effected by sliding
the cylinder and parts connected with it along the beam or girder a, which
may be done in any convenient manner, as, for example, by a rack and pinion,
but it is preferred to employ right and left handed screws working one within

page_text: the other, as is shewn in the Drawing. One of these screws u is fixed to the
top of the cylinder, and passes up within the screw, which also passes through
a nut fixed in the top of the globe a¹, and at the end of the screw
wheel, by turning which the tool holder m is pressed forward.
is a hand
Figure 1, Sheet 2, is a front view, Figure 2 is a longitudinal section,
and Figure 3 is a transverse section of a machine of very similar con-
struction. In the machine in place of the ring being fixed to the bed
or carriage, it is mounted thercon on trunnions, which gives a wider
range for the adjustment of the direction of the boring tool, the valve also in
place of being actuated by a single incline and a spring, is worked by a double
incline g (see Figures 5 and 6), which acts on two projecting arms f*, f*,
on the valve spindle, and moves the valve first in one and then in the other
direction. The tool and tool holder in this apparatus are raised by a spiral
spring, in place of by a ring-from spring, as before described, and the form
of the spring for pressing on the driver s is also changed.
Having thus described the nature of our said Invention, and the manner
of performing the same, we would have it understood that we make no claim
to any of the parts separately, nor do we confine ourselves to the details; but
what we claim is the combination herein described.
In witness whereof, I, the said Ferdinand Carl Philippson, have hereunto
set my hand and seal, this First day of April, in the year of our Lord
One thousand eight hundred and fifty-nine.
