Improvements in Hand Power Drilling Machines.
I, THOMAS BRADLEY, 224, Avenue Parade and Alexandra Works, Accrington,
in the County of Lancaster, Engineer, do hereby declare the nature of this inven-
tion to he as follows:-
-
My invention relates to hand power drilling machine & is for improvements
on my former invention described in the Specification No. 6919 A.D. 1895 drilling
machines constructed to my invention may be used either as a bench drill or
wall drill. The principal part of my invention consists in the use of loose
socket as heairin after described. To adapt the machine for use either as a bench
drill or wall drill as the case may be in the frame of drilling machine I make
a socket in such a position & direction that the machine may be clamped to a pillar
or a rod projecting from a bracket clamped to the wall.
When the machine is to be used as a bench drilling machine I fix a rod into
the socket in the frame the said rod having a socket on it at right angles to
its length by means of this socket piece the machine may be clamped to a bench
or to a wall at any angle to the same.
To adapt the loose socket piece for use with pillar or rod of different sizes I
may make the parts forming the socket in one or more parts.
In a modification I may cast the frame without any socket in it the socket in
this case being formed in a separate piece or pieces bolted or otherwise required
to the frame.

Improvements in Hand Power Drilling Machines.
I, THOMAS BRADLEY, 224, Avenue Parade and Alexandra Works, Accrington,
in the County of Lancaster, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
My invention relates to hand power drilling machines and for improvements
on my former invention described in Specification No. 6919 A.D. 1895. Drilling
machines constructed according to my invention may be used either as bench
drilling machines or wall drilling machines,

page_text: The principal part of my invention consists of a loose socket or arm as herein
after described, to adapt the machine for the use either as a bench drill or as a
wall drill as the case may be.
Fig. 1 and Fig. 2 of the accompanying drawings illustrates the manner in
which my loose sockets or arms may be applied to drilling machines. Fig. 1
shows the usual position as standing on a bench, with arm or socket C carrying
frame D, and forms a bench drilling machine. The socket C is so constructed
that it can be bolted, or otherwise secured, to the head D of drilling machine
instead of being part of the head as shown in my former invention No. 6919-
A.D. 1895.
To convert Fig. 1 into a wall drilling machine arm or socket C is dispensed with
and bracket A is bolted or fixed to wall, and spindle B is placed in aperture F
of frame D which thus forms a wall drilling machine (as shown in Fig. 2 of Patent
No. 6919 A.D. 1895).
Fig. 2 of the accompanying drawings illustrates the manner in which my new
two-way socket may be applied to ordinary drilling machines, and by removing
spindle B from its present position and placing it in aperture F and bolting or
fixing bracket A to wall will form a wall drilling machine.
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:-
By the use of arms or sockets C and E as described bench drilling machines
can be converted into wall drilling machines, or vice versâ as shown in the accom-
panying drawings.
