I, HERBERT HAMPTON HALL of Wavertree in the County of Lancaster, Coal
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the enabling of the operator to turn the tool
with greater ease than where at each turn he has to take fresh hold, and consists in
the application of the ratchet clutch to drilling, boring, etcetera, by hand.
I will describe my invention first as applied to a cork-screw. On the spindle
immediately above the cork-screw proper, I place a crown ratchet wheel, and
sliding and rotating freely, on the cylindrical shank, place a second crown
ratchet wheel to which is attached the handle. The upper part of the hole in this
crown ratchet wheel is squared, and a square knob terminates the shank or
spindle. In driving the cork-screw, the handle is turned to and fro till it is
driven, the handle crown ratchet wheel sliding freely over the other in the back
stroke. In withdrawing the screw the handle is pulled back till the square knob
fits the square hole, it is then rigid in the spindle. In a precisely similar manner,
I apply my invention to gimlets, brad-awls, and screw-drivers. In the case of
drilling or tapping braces, and the like, the crown wheel to which the handle is
fixed in the manner of a lever, is kept to the other crown ratchet wheel by a coiled
or other spring on the brace spindle, pressing between the handle and the spindle
head, which latter need not be squared in the case of drilling braces, but must be in
tapping, so as to withdraw the tap.

Purposes where a Tool or Bar is Revolved by Hand while

I, HERBERT HAMPTON HALL of Wavertree in the County of Lancaster, Coal
Merchant do hereby declare the nature of this invention and in what manner the
same is to bo performed, to be particularly described and ascertained in and by
the following statement:-
(This invention has for- its object the enabling of the operator to turn the tool
with greater ease than where at each turn he has to take fresh hold, and consists
in the application of the ratchet clutch to drilling boring, etcetera by hand.
I will describe my invention by aid of the accompanying drawing, illustrative of
an auger or tapping brace. It is obvious however that the same mechanism
modified to suit is applicable for cork-screws, screw drivers, and the other articles
set forth in the title. A is the auger, tap, or other tool, it has preferably a
shoulder B to prevent it going too far into C. C is a ratchet piece, having a hole
square or polygonal to fit the square or polygonal shaft of A enclosed within it,
Dis the main body of the frame of the brace, having complementary ratchet teeth
to those of C below, and similar ratchet teeth above, but pointing, in the opposite
direction. Shaft A passes up through a round hole in D, sufficiently large for A to
turn freely in it, without unnecessary play. EE are two lugs attached to D,
and carrying handle F securely wedged therein, G crown ratchet having teeth com-
plementary to those on D, and a square or polygonal hole to fit the squared part
of lessened diameter of shaft A, and resting against a shoulder on A, H check nut
on screwed end of shaft A, holding G down onto it.
The mode of action is as follows;
To tap or drill, the operator allows D to rest on C and oscillates the handle to
and fro horizontally when turning in one direction; the teeth in C and D catch,
and cause the tool to drill, or tap, when turned in the other direction, the teeth
ride over each other, and the operator gets a fresh vantage ground.
To withdraw the tap, auger, or for that matter cork screw, the handle is lifted
up, and the reverse action takes place, the ratchets on D and G coming into play,
instead of those of D and C. It is obvious that similar mechanism on a smaller
scale will do for corkscrews, and that by inserting a wedge or very strong spring
between H and the handle when withdrawing a screw, the tool can be used in the
ordinary manner, as a screw driver for withdrawing screws, and in tho patent
ratchet manner for driving them. Except however for a screw driver almost
exclusively used for driving, and not withdrawing, I do not recommend this
invention for screw drivers, and I prefer when it is to be used for driving only, to
insert a coiled spring between D and G, and do without the ratchet teeth at this
point, leaving two plane surfaces.

page_text: 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 ;
1st. The manufacture and use of actuating apparatus for corkscrews, screw-
drivers, tapping, boring, or other tools where the bar or tool is revolved or
oscillated, while being pressed forward, substantially as described and illustrated
in the accompanying drawings, no claim being made for ratchet and pawls used on
the plan of the ordinary "ratchet brace," but only where a crown ratchet wheel, or
its mechanical equivalent attached to a handle, acting longitudinally on the axis of
the tool, freely rotates on the tool, and gears into a ratchet wheel, or ratchet
wheels on the tool, capable of rotation only with the tool, substantially as described.
2nd. The combination of the handle F, carrying double crown wheel D, and
revolving freely on the tool, with the two ratchet wheels, one above, and the other..
below, capable of revolving only with the tool, and having their teeth pointing in
opposite directions, substantially as and for the purposes described.
