An Improved Hand Drilling Tool.

page_text: An Improved Hand Drilling Tool.
I JOHN JAMES WHITTAKER of 31 Fitzhamon Embankment, Cardiff, in the
County of Glamorgan Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to hand drilling tools worked by ratchet or friction.
The improvement is designed with the object of providing a tool which can be
worked to great advantage in various places and especially with regard to the
various sizes of holes and different lengths of leverage which are obtained.
In carrying out this invention I use a ratchet or friction drill head with a short
handle, the end of which is formed to receive a second lever or handle.
This handle is provided with two holes at right angles to each other in one end
and made to form a joint with a third handle or lever at the other.
In this joint I make preparation for two studs so that a third handle can be
placed at right angles to the second lever or made to form a straight continuous
lever with the second one.
The second lever forms the he part of the joint and has three holes at equal
distances from each other, and the third lever the she part of the joint.
The third lever at the joint part has two holes which are made to coinside with
the holes in the second lever, for the reception of two studs. One of these studs
can be taken out and the third leyer swivelled on the other stud either on a straight
line or at right angles to the other, or both studs can be taken out where the space
will not allow the third handle to be used.
The other end of the third lever is made with a hole preferably square for the
reception of a drill or other article.
This drill may be used :-
Firstly. With a short handle as an ordinary ratchet or friction drill.
Secondly. With the second lever put on the end of the first to form a longer
lever.
Thirdly. With the third lever used in the same straight line as the first & second
levers.
Fourthly. With the second lever put at right angles to the first and the third
lever at right angles to the second, the three levers being in the same plane, the
first and third being parallel to each other, thus forming a brace.
The hole at the end of the third lever is for the reception of a drill or other
article.
This ratchet or friction drill has the advantage of being used in the various ways
described with the three lengths of lever and as a brace where the full circular
motion can be used.

of Lancaster, Engineer, (late of 31 Fitzhamon Embankment Cardiff) do 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:-
This invention relates to hand drilling tools worked by ratchet or friction.
The improvement is designed with the object of providing a tool which can be
worked to great advantage in various places and especially with regard to the
various sizes of holes, and different lengths of leverage which are obtained.

Figure 3 is a side elevation when used with full leverage.
with a
a,
In carrying out this invention I use a ratchet or friction drill head
short handle the end of which is formed to receive a second lever or handle b.
This handle b, is provided with two holes at right angles to each other in one
end and made to form a joint with a third handle or lever c at the other.
In this joint I make preparation for two studs d, and e; so that a third handle c
can be placed at right angles to the second lever b, or made to form a straight
continuous lever with the second one b, Fig. 3.
The second lever b forms the he part of the joint and has three holes d, e, f, at
equal distances from each other, and the third lever c, the she part of joint.
The third lever c, at the joint part has two holes d, and e which are made to
coincide with the holes in the second lever, for the reception of the two studs d,
and e.
One of these studs e, can be taken out and the third lever c, swivelled on
the stud d either in a straight line or at right angles to the other, or both studs d,
and e, can be taken out where the space will not allow the third handle c to
be used.
The other end of the third lever c is made with a hole G, preferably square for
the reception of a drill or other article.
This drill may be used :-
Firstly with a short handle as an ordinary ratchet or friction drill.
.
Secondly with a second lever b put on the end of the first to form a longer
lever, Fig. 3.
Thirdly with the third lever used in the same straight line as the first lever d
and second lever b, Fig. 3.
Fourthly with the second lever 6 put at right angles to the first lever a, and the
third lever c, at right angles to the second, the three levers being in the same
plane, the first and third being parallel to each other, thus forming a brace,
Fig. 1.
This ratchet or friction drill has the advantage of being used in the various ways
described, with the three lengths of levers and as a brace where the full circular
motion can be used.
I wish it to be understood that I do not confine this lever arrangement to the
particular ratchet head shewn as any form of ratchet can be used.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1st. The combination of a ratchet or friction drill head with an arrangement
of levers as particularly described and shewn in drawings or its mechanical
equivalent.
