page_text: LETTERS PATENT to George Hodgson and James Pitt, both of Cleckheaton,
in the County of York, Machine Makers, for the Invention of "IMPROVE-
MENTS IN DRILLING APPARATUS FOR HAND OR STEAM POWER, ADAPTABLE ALSO
AS A VICE AND FOR LIFTING PURPOSES."
Sealed the 30th June 1865, and dated the 3rd January 1865.
PROVISIONAL SPECIFICATION left by the said George Hodgson and
James Pitt at the Office of the Commissioners of Patents, with their
Petition, on the 3rd January 1865.
We, GEORGE HODGSON and JAMES PITT, both of Cleckheaton, in the County
of York, Machine Makers, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN DRILLING APPARATUS FOR HAND OR STEAM POWER,
ADAPTABLE ALSO AS A VICE AND FOR LIFTING PURPOSES," to be as follows:-
This Invention has for its object improvements in apparatus for boring,
drilling, and other purposes. The various parts are so arranged and accurately
fitted that by changing one to another they can be readily adjusted for four
different motions, and form a combination of drill, rack drill, vice, and screw
jack, applicable either for hand or steam power. The stand drill consists of a
lever, through one end of which works a grooved spindle capable of sliding
thereon, which spindle has also a longitudinal groove, a set screw entering
therein to prevent the lever turning on the spindle; at the bottom of the

page_text: spindle the drill is fixed. The lever carries two wheels, one a bevel and the
other a spur wheel, and a stud on the lever carries a hollow shaft on which is
fixed another bevel wheel, which wheel gears with the first-named bevel wheel.
The lever also carries a short vertical spindle having a spur wheel at each end,
the upper spur wheel gearing with the spur wheel on the lever and the lower
one gearing with a worm wheel fixed in a collar below the lever in which the
drill spindle works. The apparatus when in use is fixed to a stand having two
jaws, the lower one fixed and the upper one working by means of a set screw
on two uprights, which uprights support a cross head through which passes a
vertical shaft carrying the arm of the lever. The vertical shaft and the arm
of the lever are both adjustable by set screws. Motion is given to the
apparatus by means of a handle fixed on the loose shaft carried by the stud of
the lever, or when worked by steam power a pulley is fixed thereto which is
driven direct from the engine by a band or strap. The rack drill is used
without the stand and vertical shaft, the round arm of the lever serving as a
handle. It is formed by removing the worm wheel from the collar below the
lever, placing it in a cap or drill holder, then fixing it on the top of the drill
spindle and bringing into gear a pawl fixed on the lever. The stud carrying
the loose shaft is removed from the lever. To form the lifting apparatus the
worm wheel is taken off the top of the drill spindle, placed in the hollow
of the cross head of the stand, the drill spindle (inverted) is passed through the
cross head, and the stud from off the lever carrying the loose shaft and having
a mitre wheel at the end is then fixed on the cross head. The grooves of the
mitre wheel work in the worm wheel fixed in the cross head. The vice
is formed by fixing the stand horizontally to any convenient place by means
of a bolt passing through a T-headed slot hole cut in the stand for that
purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Hodgson and James Pitt in the Great Seal
Patent Office on the 1st July 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HODGSON and JAMES PITT, both of Cleckheaton, in the County of York,
Machine Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of January, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-ninth year of Her

page_text: reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said George Hodgson and James Pitt, Her special licence that we, the
said George Hodgson and James Pitt, our executors, administrators, and
assigns, or such others as we, the said George Hodgson and James Pitt,
our executors, administrators, and assigns, should at any time agree with
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
DRILLING APPARATUS FOR HAND OR STEAM POWER, ADAPTABLE ALSO AS A VICE AND
FOR LIFTING PURPOSES," upon the condition (amongst others) that we, the
said George Hodgson and James Pitt, our executors or administrators, by
an instrument in writing under our, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said George Hodgson and James Pitt,
do hereby declare the nature of our said 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 for its object improvements in apparatus for boring,
drilling, and other purposes. The various parts are so arranged and accurately
fitted, that by changing one to another they can be readily adjusted for four
different motions and form a combination of drill, rack drill, vice, and screw
jack, applicable either for hand or steam power.
The accompanying Drawing exhibits an apparatus in which our Invention
is carried out; Fig. 1 being a front elevation of the drill; Fig. 2, a front
elevation of the driving motion; Fig. 3, a plan of lower or fäst jaw; Fig. 4
the drill holder and worm wheel set for rack drill; Fig. 5, a transverse section
of stand and jaws; Fig. 6, a front elevation of the lifting jack. Similar
letters of reference indicate corresponding parts in the several Figs. The
drill consists of a lever A, through one end of which works a grooved spindle
B, B, capable of sliding thereon, which spindle or screw has also a longitudinal
groove C. At the bottom of the spindle or screw the drill is fixed. The lever
carries two wheels D, E, one a mitre wheel and the other a spur wheel; and a
stud on the lever shown at P, Fig. 2, carries a hollow shaft on which is fixed
another mitre wheel b, Fig. 2, which gears with the first-named mitre wheel
D, at Fig. 1. The lever A also carries a short vertical spindle F, having a

page_text: spur wheel G and H at each end.
The upper spur wheel G gearing with the
spur wheel E on the lever, and the lower one H gearing with the worm wheel
I, fixed in a collar below the lever in which the drill, spindle, or screw B, B,
works. The grooved spindle or screw B, B, is driven by means of a fast key
in the boss of the mitre wheel D, which works freely in the longitudinal
groove C. Wheels E, H, and I are of one size, while the wheel G is one cog
larger, so that at each revolution of wheel E, which is fast to the mitre wheel
D, wheels G, H, and I lose one cog. By so doing worm wheel I, with a
thread in the boss fitting the grooves of spindle B, B, presses down the drill with
perfect regularity at each revolution of the grooved spindle. The apparatus
when in use is fixed to a stand J, having two jaws; the lower one fixed
(Fig. 8) and the upper one working by means of a set screw K, with a collar
on its point on the under side of the fast jaw, which gives it the advantage of
fastening the apparatus in any position required, while the fast jaw has a
T-headed slot hole, shown at Fig. 3, thereby allowing the apparatus to be
secured by either bolt or jaws. The upper or loose jaw works on two uprights
L, L, which support a cross head N, through which passes a round vertical
shaft O, capable of being raised or lowered or moved sideways. The vertical
shaft has a round hole through its thickest part to carry the arm of the lever
A. The vertical shaft O, and the lever A, are both adjustable by set
screws, and by this means the drill will bore at any point of a circumference
vertically, the extreme radius being the full length of lever A; also, the drill
will bore at any angle formed by turning the lever A in its rest in the shaft O,
and by removing the shaft O from the cross head N, the drill will bore
horizontally by placing the lever A in the vacant place in the cross head N.
Motion is given to the apparatus by means of a slotted handle M, Fig. 2, the
radius of which may be increased or diminished as required, according to the
size of the hole to be bored; and is adjusted and fixed on the loose shaft
carried by the stud of the lever P, and when worked by steam power a pulley is
fixed thereto instead of a handle, and driven direct from the engine by a band
or strap. The rack drill is used without the stand J and the vertical shaft O,
the round arm of the lever A serving as a handle. It is formed by removing
the worm wheel I from the collar below the lever A, placing it in a cap or
drill holder S, Fig. 4, also the small set screw T, Fig. 5, then fixing them on
the top of the drill spindle or screw B, B, to set up the drill; and bringing
into gear a paul or catch V, Fig. 1 (fixed on the lever A), which is kept in
and out of gear by a spring. The stud P, Fig. 2, carrying the loose shaft is
removed from the lever. To form the lifting apparatus the worm wheel I is
taken from out of the cap or drill holder S, and placed in the hollow of the

page_text: cross head of the stand, as shown at Fig. 6. The drill spindle B, B, inverted,
is passed through the cross head, and the stud P (Fig. 2) carrying the loose
shaft and having the mitre wheel on with worm attached is then easily fixed
in a suitable hole in the cross head at X, Fig. 6. The grooves of the worm
attached to mitre wheel 6 work in the worm wheel fixed in the cross head.
The cap or drill holder S is also placed on the top of the drill spindle, as
shown at Fig. 6. The vice is formed by fixing the stand J horizontally to any
convenient place by means of a bolt passing through the T-headed slot hole in
the lower or fast jaw, Fig. 3. The apparatus is not confined to the motions
specified.
We claim, 1st, the jaws, by which the apparatus is more readily fixed and
holds much faster than by other means.
2nd, the adaptation of worm wheel; the machine being a self driver, and
allowing the drill to bore the whole length of the screw without a reverse.
3rd, two different motions can be employed at one and the same time, if
required.
4th, when fixed the drill will bore at an angle of any degree in three distinct
planes without removing the stand.
5th, when used as a rack drill the lever is not confined to any given part of
the grooved spindle.
6th, being applicable to hand or steam power.
7th, the combination of drill, rack drill, vice, and screw jack.
In witness whereof, we, the said George Hodgson and James Pitt,
have hereunto set our hands and seals, this Twenty-sixth day of
June, One thousand eight hundred and sixty-five.
Signed, sealed, and delivered by the
said George Hodgson and James
Pitt, in the presence of
