PROVISIONAL SPECIFICATION.
Improvements in Hand Drilling Apparatus or Tools.
I, ARTHUR ALBERT TATTERSALL of Mill Hill Tool Works, 5 Grantham
Street, Mill Hill, Blackburn, Engineer do hereby declare the nature of this
invention to be as follows:-
This invention relates to a tool which combines in one a ratchet and a crank
brace and a drill.
The present invention is mainly a further developement of my prior invention
No. 10,497 dated 20th June 1891.
In carrying out my present invention under one arrangement I fit into the stock
or drill holder of the combined ratchet and crank brace, described in my aforesaid
Patent, a spindle having a taper squared and pointed end. On this spindle is a pop
or projection on which is fitted a toothed wheel driven by means of a small handle.
This wheel gears in the same manner as in an ordinary drill with a bevel wheel at
the upper end of a sleeve carried on the spindle and the sleeve is provided with the
ordinary bit holder or chuck into which is inserted the boring bit.
In some cases the spindle may be made with two pops having holes in them, into
one or other of which the pivot pin of the driving wheel may be placed and secured
by a pin. This arrangement is applicable when two speeds are desired.
If so desired the pop may be made one with a collar or sleeve which is moveable
on the spindle. The collar or sleeve can be held in any desired position on the
spindle by means of a pinching screw. In this case the construction of the
drill may in its other features be the same as an ordinary drill with one or
two speeds.
Under a slight modification the stock or bit holder of the ratchet brace or crank
brace may have a pop cast on it and the bevel wheel be pivotted to said pop instead
of to the pop on the spindle. The spindle of the drill part of the tool is made with
a point at its end.
If desired the drill part of the tool may be combined in the same manner with an
All that is
ordinary ratchet or with an ordinary crank brace with feeding screw.
necessary for this purpose being to fit the tapered end of the spindle in the bit stock
or holder of the ratchet or brace in the saine manner as an ordinary bit is fitted. A
pinching or thumb screw may be provided for holding the end of the spindle tight
in place. If desired the spindle may be round throughout its length and be smaller
than the square hole in the holder or stock of the crank or ratchet brace. In this
case the end of the spindle would be held in place by a pinching screw passed
through a pop made on the back of the holder for the reception of the spindle.
This combination tool can be used for various purposes as it combines practically
three tools vizt., a crank brace, a ratchet, and a drill. The parts can be taken apart
and used separately if so desired.
With the tool holes can be easily bored in metal from 16 to 11".
The device is equally applicable for drilling as a drill, or boring as a ratchet,
or a brace.
In some cases a feed screw may be fitted in a pop on the bit holder of the crank
part of the ratchet brace described in my aforesaid Patent and the drill spindle be
fitted in the bit holder of the ratchet part of said brace.

Improvements in Hand Drilling Apparatus or Tools.
I, ARTHUR ALBERT TATTERSALL, of Mill Hill, Tool Works, 5 Grantham
Street, Mill Hill, Blackburn, 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 relates to a tool which combines in one a ratchet and a crank brace
and a drill.
The present invention is mainly a further development of my prior invention
No. 10497 dated 20th June 1891.
In carrying out my present invention under one arrangement I fit into the stock
or drill holder of the combined ratchet and crank brace, described in my aforesaid
patent, a spindle having a taper squared and pointed end. On this spindle is a pap
or projection on which is fitted a toothed wheel driven by means of a small handle.
This wheel gears in the same manner as in an ordinary drill with a bevel wheel at
the upper end of a sleeve carried on the spindle and the sleeve is provided with the
ordinary bit holder or a chuck of any kind into which is inserted the boring bit.
In some cases the spindle may be made with two paps having holes in them, into
one or other of which the pivot pin of the driving wheel may be placed and secured
by a pin. This arrangement is applicable when two speeds are desired.
If so desired the pap may be made one with a collar or sleeve which is
movable on the spindle. The collar or the sleeve can be held in any desired position
on the spindle by means of a pinching screw. In this case the construction of
the drill may in its other features be the same as an ordinary drill with one
or two speeds.
Under a slight modification the stock or bit holder of the ratchet brace or
crank brace may have a pap cast on it and the bevel wheel be pivotted to said
pap instead of to the pap on the spindle. The spindle of the drill part of the tool
is made with a point at its end for lever or other pressure.
If desired the drill part of the tool may be combined in the same manner with an
ordinary ratchet or with an ordinary crank brace with feeding screw. All that is
necessary for this purpose being to fit the tapered end of the spindle in the bit stock
or holder of the ratchet or brace in the same manner as an ordinary bit is fitted.
A pinching or thumb screw may be provided for holding the end of the spindle
tight in place. If desired the spindle may be round throughout its length and
be smaller than the square hole in the holder or stock of the crank or ratchet
brace. In this case the end of the spindle would be held in place by a pinching
screw passed through a pap made on the back of the holder for the reception
of the spindle.
This combination tool can be used for various purposes as it combines practically
three tools vizt., a crank brace, a ratchet, and a drill. The parts can be taken apart
and used separately if so desired.
With the tool holes can be easily bored in metal from 1 to 11".
The device is equally applicable for drilling as a drill, or boring as a ratchet, or
a brace.
In some cases a feed screw may be fitted in a pap on the bit holder of the crank
part of the ratchet brace described in my aforesaid Patent and the drill spindle be
fitted in the bit holder of the ratchet part of said brace.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings whereon :-
Figs. 1 to 8, show different forms of the combination tool.
On the drawings the same reference letters wherever repeated indicate the same
or similar parts.

page_text: In Fig. 1 a tool comprising in one the crank brace set forth in the Specification
of my prior Patent No. 10497 of 1891, a ratchet and a drill is shown. As will be
seen the brace a is of the same construction as in my prior Specification aforesaid
and is provided with the removable ratchet b. Fitted into the tapered hole in the
boss at of the brace is the tapered lower end of the spindle c' of the drill c. This
drill, which may be otherwise of the usual construction is made with a cranked or
bent pap or stud c² which is fitted to and capable of sliding up and down the
spindle c. The stud is clamped to the spindle by the pinching screw c³. The
driving gear wheel c is mounted on the extremity of the bent part of the stud as
shown.
The object of making the stud bent, as shown, is to support the wheel c' at an
angle so that it will clear the boss a' of the brace or the boss b' of the ratchet if the
drill is fitted into the latter.
This tool is specially adapted for working in metal and it will be found very
useful by mechanics and others as it practically combines in one, three separate
tools, viz.; a drill, a brace, and a ratchet. When the drill is fitted in the boss a' as
shown the tool can be used like an ordinary drill and be driven by the handle c³, or
it may
be turned by the crank a and be used in the same manner as an ordinary
brace. When it is used as a brace the ratchet part b should be turned round to a
position at right angles to that shown so that the screw would not penetrate the
body, or breast, and the ratchet head would be made to serve as a breast plate. If
so desired the parts can be taken asunder and the drill spindle c¹ be fitted into the
ratchet 6, in the same manner as shown at Fig. 3. In this case the tool serves as a
ratchet with a short lever arm but the arm can be lengthened by securing the
crank a to it in the manner shown at Fig. 3 of my prior Specification aforesaid.
In this case the ratchet feed would be put on by the screw in the ordinary
manner.
As will be seen the lower end of the drill spindle c' is made with a point or
centre con it which serves the same purpose as the point or centre described in the
Specification of my prior Patent for breast drills No. 519 of 1892.
In Fig. 2 the ratchet b is replaced by a swivel head 63 which is provided with a
feeding screw 6. This swivel head when turned round to a position at right angles
to that shown serves the purpose of a breast plate. The head is removably secured
to the crank a in the same manner as the ratchet arm Fig. 1, i.e. by being fitted in
a hole in the head of the brace and secured therein by a pinching screw. The head
of the crank is, as set forth in the Specification of my prior Patent No. 10497
of 1891, made with two holes, at right angles to one another, for the reception of
the arm of the swivel head. In this case the tool can be used as either a cranked
brace or as a drill.
In Fig. 3 the drill is shown as fitted in an ordinary ratchet and the pressure is
applied by turning the screw of the ratchet. As will be readily understood the tool
can in this case be used either as a ratchet or as a drill.
The drill may in the same manner be fitted in any ordinary brace.
When the drill is to be fitted in a brace or a ratchet the spindle has its lower
tapered end squared so as to fit into and turn with the drill holder of the brace or
the ratchet. The lower extremity of the spindle would preferably, in all cases, be
made with a centre or point as at Fig. 1.
Fig. 4 shows the drill fitted into the ratchet 6 of Fig. 1 instead of into the brace.
In this case, as shown, the crank is reversed and the screw is removed from the
ratchet and inserted in the boss of the crank, which may be tapped for its reception.
The feed is put on by the screw. The tool can in this case be used, at will, either
as a drill, a ratchet, or a brace.
Fig. 5 shows a double gear driving wheel as fitted on a pap or boss e made in one
with or secured to the boss of the brace. The spindle c' may, in this case, be round
and be provided with a steel point or centre.
The spindle is secured to the boss by a pinching screw e'. The wheel c* may be
supported on the pap e by a washer e³ and screw
•

page_text: In Fig. 6 a breast drill spindle f is shown as fitted on the spindle of the drill as
an extension. The drill, as shown, is made so as to fit any ordinary brace or
ratchet and the lower end of its spindle is cut with a screw thread. The breast
drill spindle is made with a hollow part f¹ which is tapped, as shown, for the
reception of the screwed end of the spindle c. When the centre or point of the 5
breast drill attachment is placed against something stationary the part f¹ can be
turned round in the same manner as an ordinary ratchet so as to give the
necessary feed. Lever or pressure can be brought to bear on the point of the
breast plate.
As will be seen the drill can be used with the attachment in the same manner as 1
an ordinary breast drill.
Fig. 7 shows a removable lever handle 9 which may be fitted on the ratchet
part b so as to give greater leverage. The handle is made with a socket g' into
which the ratchet arm is fitted and held in place by a pinching screw.
To make the taper of the drill part of the tool fit a ratchet square hole and a 1
joiners' brace square hole a connecting piece m (Fig. 8) must be used. The end m¹
of the connecting piece fits into the joiners' brace.
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
consider novel and desire to claim is :--
1. The several constructions of the combination tool substantially as hereinbefore
described with reference to the drawings annexed.
2. The combination with a ratchet or brace of a speed drill, substantially as
herein before set forth.
