COMPLETE SPECIFICATION.
Improvements in Deep Boring Apparatus.
I, ANTON RAKY, of Erkelenz, in the Province of Rhine, German Empire,
Engineer and Manager, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a boring apparatus, more especially to that kind
of apparatus, in which the boring tool is carried by a rope and is actuated by an
oscillating beam.
For the purpose of allowing a continual actuation of the boring tool, the rope
is wound upon a cylinder rotated by hand or automatically and thence conducted
over a roller fixed to the oscillating beam, so that the free extremity of the
rope carrying the boring tool may be moved by the lever arm in the manner
necessary for boring. Whilst the extremity of the rope carrying the boring tool
is moved up and down under the influence of the beam, the cylinder upon which
is wound the other extremity of the rope is rotated slowly so as to increase the
length of the rope according to the increasing depth of the bored hole without
the actuation mechanism (the lever arm) being influenced or stopped in any way.
In the rope I insert a tackle upon which the beam acts directly. When a tackle
is intercalated, the oscillation of this beam may be of very slight nature to effect a
rapid movement of the boring tool.
My invention will be the better understood with reference to the accompanying
drawing, in which my invention is represented schematically.
The beam a is arranged in suitable manner within a frame b; c is a crank-shaft
to which motion is given by any suitable source of power. The motion of the
crank-shaft is communicated to the beam in suitable manner so that an oscillating
movement is given to the latter. The free extremity of the beam a is provided
with a roller d. e is a rope carrying on its free extremity the boring tool. This
rope is wound upon a cylinder g. By rotation of a hand-wheel p connected to the
cylinder g by an endless chainn a larger or less quantity of rope can be unwound.
From the cylinder g the rope is conducted over a roller f fixed to the frame b; from
here over roller d located on the free arm of the beam a, and then over a second
roller h of the frame b to the boring tower k located vertically above the hole to
be bored. Here the rope hangs down freely and carries at its lower end the boring
tool m.
It is advantageous to render the bearing of one of the employed rollers
somewhat elastic. In the drawing springs are employed for this purpose. These
springs act upon the roller d, but it is evident that these springs can be arranged
to any of the other rollers h or r.
As clearly to be seen form the drawing the rope e is guided so, as to form a
tackle for the purpose to double the movement of the beam and consequently to
double the movement of the free extremity of the rope carrying the boring tool m.
It is evident that by a greater number of rollers around which the rope is guided,
the movement of the boring-tool m can be increased to any desired degree.

page_text: The boring by means of my improved apparatus is effected in the following
manner:
When motion is given to the crank c the same is communicated to the beam a
which then will effect a constant oscillating movement. This movement is again
communicated to the rope e and consequently to the boring-tool m which will
descend deeper and deeper into the hole 7. Corresponding to the increasing depth
of this hole a corresponding quantity of rope is unwound by means of the hand-
wheel p by lengthening the rope, the boring effect is not altered in any way.
The wheel for unwinding rope from the cylinder g need not to be rotated by
hand but can be connected to the machine giving motion to the crank c, so that the
unwinding of the rope also is effected automatically.
The automatic unwinding of rope e is of great importance when the hole is to
be bored in a ground of equal consistency. The tackle formed by the different
rollers is of importance for the boring effect inasmuch as the rapidity of the
movements of the boring tool is increased in conformity.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
In a boring apparatus with oscillating beam, the combination of the beam (a)
with a rope (e) carrying the boring-tool (m) and conducted to the boring tower
in the form of a tackle, a cylinder (g) upon which is wound the rope a hand-
wheel (p) connected to the drum (g), rollers (h) and (f) fixed to the frame (b)
of the apparatus and a roller (d) elastically located upon the beam, all rollers
forming guides for the rope, for the purpose and substantially as set forth.
