COMPLETE SPECIFICATION.
Improvements in and connected with Boring Apparatus for
Deep-borings.
·I, ANTON RAKY, of Erkelenz, in the Province of the 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:-
My invention relates to improvements in boring apparatus for deep-borings, more'
especially to a mechanism for winding up the boring rods in apparatus for deep
borings.
The rods in apparatus for deep borings generally are of considerable weight so that
for lifting these rods either a powerful engine or the intercalation of many tackles is
necessary. As the weight of these boring rods varies very much, it is not possible to
take good use of a machine when for instance a machine adapted to lift a great
weight, must lift short rods. So it would be necessary that when rods of 300 meters
have to be lifted, many tackles must be intercalated and the engine still works
very slowly.
When now the weight lessens after a certain number of rods have been taken out
of the hole, the further lifting is a very slow one in accordance with the power of the
engine, or the tackles which have first been intercalated, must be taken off again.
This manipulation at some places will be a very difficult one and often causes an
immense loss of time.
The object of the present invention is to provide a mechanism for winding up ropes
by means of which in the simplest manner three or more different degrees of rapidity
can be attained. Consequently the variation of the weight to be lifted does not
influence the engine in any way but the work always will be effected in a uniform
manner.
The mechanism essentially consists of two or more cylinders having a common axle
and being rotated by the engine. The weight, that is to say, the boring rods are
suspended on a roller b which itself is carried by a rope arranged so as to form
tackles. The extremities of this rope are either wound upon the cylinders of different
diameter, or its one extremity is fixed whilst the other is wound upon the cylinder
having the diameter necessary for the necessary rapidity for lifting.
My invention is represented schematically in Figs. 1-3 of the accompanying
drawing.
In the drawing two cylinders of different diameters a¹ a² are represented. The
carrier rope is guided round the roller b from where the ends are conducted over
rollers c¹ c² to the double-cylinder a¹ a².
In Fig. 1 the mechanism is represented so that the extremities of the rope are
wound in the same direction upon the cylinders a¹ a².
Fig. 2 shows the arrangement when the extremity of d² fixed at e, whilst d¹ is
wound around the cylinder of large diameter a¹.
At last Fig. 3 shows the end of the rope d¹ fixed at f, whilst d is wound round
the small cylinder a².

The proportion of the different rapidities is 1:2:3. In consequence the engine
used for lifting the weight can constantly work under about the same proportions
with three different variations in rapidity.
It has to be borne in mind, that an alteration of the arrangement can easily be
effected when each time equal lengths, i.e. one boring rod is lifted.
The length of the carrrier rope d¹ d² is chosen so that when starting the lifting
operation, both extremities of the rope are free, so that they may be wound either
around the cylinders a¹ a² or fixed to any of the points e or f. The example repre-
sented in Figs. 1-3 will be sufficient, but it is quite evident that when three or
more cylinders of different diameters are employed, the proportions of transmission
can be increased immensely.
Having now particularly described and ascertained the nature of any said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In a mechanism for winding up boring rods in apparatus for deep borings, the
combination with cylinders of different diameter arranged upon a common axle taking
up the extremities d¹ d² of the carrier-rope, one of which eventually might be fixed,
whilst the other is wound up, for the purpose as described.
