page_text: I, MARO BERRIER FONTAINE, of Toulon in the Republic of France Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to portable apparatus for drilling holes in situ, in ships,
girders, bridges and other iron or steel structures, in cases where a supply of water
under pressure is available, thus avoiding the labour and loss of time involved in
moving the separate plates or pieces of the structure from positions where they are
marked to stationary drills and back to their places, and also, providing for drilling
a continuous hole through a number of such plates or pieces when they are super-
posed. The machine consists of a light frame of C form on the back of which is
fixed a three-cylinder or other hydraulic motor. In the two terminals of the
C frame are formed bearings for a drill spindle having its axis at right angles
to that of the hydraulic motor and connected to it by bevil gearing within the
C frame. The drill spindle is fitted with a key way to slide through but to revolve
with the pinion that drives it and is provided at its one end with a socket to
receive the drill and at the other end with a feeding screw. By means of two
handles projecting from the opposite sides of the frame, a workman can move the
apparatus from place to place and fix it to its work as a ratchet brace is usually
fixed, or when there are holes available in the structure to which it is applied by
bolts passing through slotted holes provided in the frame.
Water under pressure
is conveyed to the motor by a flexible jointed pipe, and the discharge water is led
away by a caoutchouc pipe, suitable valves being provided to arrest or regulate
the flow. In cases where it is not convenient to fix the machine so as to drill
direct, it is used to drive a flexible shaft by which motion is conveyed to the drill.
In such a case, there is substituted in the frame for the drill spindle a more rapidly
evolving spindle without longitudinal feed, but provided with a suitable socket for
connecting to the flexible abaft.

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:—

Fig. 1 of the accompanying drawings is a side view partly in section and Fig. 2
is a front view of the frame of a machine according to this invention. It consists
of a light frame A of C form on the back of which is fixed a three-cylinder or
other hydraulic motor B. In the two terminals of the C frame A are formed
bearings for a drill spindle D having its axis at right angles to that of the hydraulic
motor and connected to it by bevil gearing E F within the C frame. The drill
spindle is fitted with a key way to slide through but to revolve with the pinion F
that drives it, and is provided at its one end with a socket to receive the drill and
at the other end with a feeding screw G. By means of two bandles H H pro-
jecting from the opposite sides of the frame A, a workman can move the apparatus
from place to place and fix it to its work as a ratchet brace is usually fixed, or
when there are holes available in the structure to which it is applied it may be
fixed by bolts passing through slotted holes provided in the frame. Water under
pressure is conveyed to the motor by a flexible or jointed pipe, and the discharge
water is led away by a caoutchouc pipe, suitable valves being provided to arrest or
regulate the flow. In cases where it is not convenient to fix the machine so as to
drill direct, it may be arranged as shown in Fig. 3 (which is a side view partly in
section) to drive a flexible shaft K by which motion is conveyed to the drill. In
such a case, there is substituted in the frame A for the drill spindle D shewn
in Fig. 1 a more rapidly revolving spindle D¹ without longitudinal feed, but
provided with a suitable socket L for connecting to the flexible shaft K.
Although I have described the motor as being driven by hydraulic pressure,
obviously where steam or other fluid under pressure is available, it may be used to.
supply the motor of the drill.
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
The construction and use of a portable hydraulic drill consisting of a portable
frame on which is mounted a drill spindle connected by bevil gear to the axis of
a three cylinder or other hydraulic motor, substantially as herein described and
illustrated by the accompanying drawings.
