PROVISIONAL SPECIFICATION.
An Improved Combination Hand Tool, suitable for Use as a Ratchet
Brace, Lifting Appliance, and partly applicable for Use as a
Spanner.
I, JOSEPH ARTHUR WADE, of 19, Old Hall Street, Liverpool, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to a simple and inexpensive construction of
combination hand tool suitable for use as a ratchet brace, for drilling holes in
confined places and also as a lifting appliance, the said tool being provided with
a special handle whereby the drill or other part to be rotated can be turned
in either direction and which is specially adapted for use as a spanner.
The body part of the tool serving as a drill holder consists of, a steel stamp-
ing, one end of which is preferably made octagonal in shape externally. This
body part is formed with two similar circular collars that are formed with notches
and are separated by an intermediate reduced part that is of circular section
and has a diameter equal to the distance between two flat sides of the octagonal
portion of the body part. Fitting the annular space between the collars is a
handle made in the form of a spanner that is supported by the notched collars.
The body part of the tool is bored, and formed with internal screw threads which
receive a setting up or feeding screw provided with a nut-like head. The setting
up or feeding screw is on the top of its nut like head formed with a projecting
point and the part which is screw threaded and enters the hole in the body part
of the drill may be hollow if desired to allow of the end of the drill or like tool
entering therein and being guided thereby.
The lower end part of the body part is suitably formed to receive the drill which
may be of square or other section so long as it is not able to rotate in the body
part when the same is turned in either direction.
The handle or spanner has projecting on each side thereof at the junction of
its two jaws, a pin the length of which is such that it extends across the two
notched collars. The pin is so shaped that when the spanner is moved in one
direction it will engage with the notches but when the spanner is moved in the
other direction it will be disengaged from the notched collars. If the spanner
is reversed or turned over the pin will engage and rotate the body part and drill
in the opposite direction. The spanner is of such a size that it can be engaged
with the upper portion of the body part of the drill holder and with the nut
like head of the setting up screw for turning one of these parts relatively to
the other for feeding the drill. The handle instead of being a separate part
may be connected if desired by a ring and chain to the body part, but so that
the drill or other tool can be revolved in either direction by simply turning the
handle over.
The tool may be used for tapping holes and for putting in screws in confined
places

page_text: The body part of the drill holder with the setting up screw may be used as
a lifting jack in which case the handle may be used as a spanner for rotating
either of the two parts whilst the other is held from moving.

An Improved Combination Hand Tool, suitable for Use as a Ratchet
Brace, Lifting Appliance, and partly applicable for Use as a
Spanner.
I, JOSEPH ARTHUR WADE, of 19, Old Hall Street, Liverpool, in the County of
Lancaster, Engineer, 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 has reference to a simple and inexpensive construction of
combination hand tool suitable for use as a ratchet brace for drilling holes in
confined places and also as a lifting appliance, the said tool being provided with
a special handle whereby the drill or other part to be rotated can be turned
in either direction and which is specially adapted for use as a spanner.
Fig. 1 shows in perspective the body part of a tool according to this invention:
Fig. 2 is a similar view of the handle or spanner detached: Fig. 3 is a vertical
section of the body part of the tool to an enlarged scale; and Figs. 4 and 5 are
cross sections on the lines A B and C D respectively of Fig. 3 showing the
handle or spanner in reverse positions.
The body part a of the tool which serves as a drill holder is octagonal in cross
section at band is formed with two similar collars c that are formed with teeth d,
the portion e between them being cylindrical in cross section, and equal in
diameter to the distance between parallel sides of the octagonal portion 6 of the
body part. The handle or spanner is so formed that its jaws will fit the part
of the body portion of the tool and can be inserted between the collars c around
the portion e; the lower end of the body part a is suitably formed to receive the drill
or screw tap which may be of square or other section so long as it is not able
to rotate in the body part when the same is turned in either direction. The nut
like head of the setting up or feeding screw g is formed with a pointed pro-
jection, and the part which is screw threaded and enters the hole in the body
part of the tool may be hollow, if desired, to allow of the end of the drill or like
tool entering therein and being guided thereby.
The handle has projecting on each side thereof at the junction of its two
jaws which are longer than usual so as to be more firmly supported between
the two collars e, a pin (Fig. 2) or pins (Fig. 6) the length of which is such that
it engages with the teeth of the two collars c. The pink is formed somewhat
like a ratchet tooth, for instance, with sides, of which, when the handle is fitted
between the two collars, one will be approximately radial to the axis of the
parte and the other approximately tangential to said circular part, and so that
when handle or spanner f is swung or oscillated about the part e in one
direction the radial side of the pin k.will engage with the teeth d, but, when
the handle or spanner is swung or oscillated in the other direction it will become
disengaged from the teeth d owing to the tangential side of the pin causing the
same to ride over the teeth d.

page_text: If the spanner is reversed or turned over as shown in Fig. 5 the pink will
engage the teeth d and rotate the body part and drill when it is swung or oscil-
lated in the opposite direction. The spanner is of such a size that the nut-like
head of the setting up screw 9 or the upper portion of the body part a can
be engaged by it for turning one of these parts relatively to the other for feeding
the drill.
The body part of the drill holder a with the setting up screw 9 may be used
as a lifting jack, in which case the handle or spanner may be used as a spanner
for rotating either of the two parts whilst the other is held stationary.
In the modification shewn in Fig. 8 the body part is formed with a shank
that is screw-threaded and adapted to receive a nut m. This nut m enters into
one end of and carries a hollow part n that is octagonal in cross section for a
part of its length and is provided at its other end with a cap piece o that is made
in one with or attached to the centre pin i.
It is evident that the body part a fitted with a drill or other tool can be more
easily and truly placed in position when the handle is removed, than can the
ordinary ratchet brace where the handle is fixed; also the present invention has
advantages over the ordinary ratchet brace which cannot be rotated in either
direction without the addition of complicated parts.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A hand tool of the kind herein referred to comprising a body portion made
in two parts, one of which is formed with annularly arranged teeth and is
adapted to be connected to the drill or other device to be rotated and the other
of which forms an endways adjustable feed device, and a detachable reversible
handle formed with a forked or spanner-like end adapted to embrace said body
part and with a tooth or projection which will engage with the teeth on the
rotatable body part, the arrangement being such that the latter can be turned
in either direction at will, substantially as described.
2. A combination hand tool of the kind herein referred to constructed, arranged
and operating substantially as described with reference to and shewn in the
accompanying drawings.
