PROVISIONAL SPECIFICATION left by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition, on the 13th
May 1864.
I, GEORGE HASELTINE, of the "International Patent Office," No. 12,
Southampton Buildings, Chancery Lane, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN PORTABLE DRILLING MACHINERY, PARTS OF WHICH ARE APPLICABLE TO
MACHINES FOR OTHER PURPOSES," to be as follows:-
The nature of said Invention consists in the novel construction and arrange-
ment of parts whereby is obtained a hand or power machine of greater
efficiency and of more universal application for the purposes of drilling metals.

page_text: In a suitable bed plate is fixed a vertical shaft; on this shaft is secured a
clamp on the front of this clamp there is a circular flange, in which two
circular slots are cut, each forming about one-third of a circle. To this flange
a corresponding flange is bolted, and to the latter is fixed a horizontal arm.
Upon this arm is fitted a movable head, to the back of which is fixed a nut
projecting through a longitudinal slot in the said arm. In this nut works a
screw running parallel with the arm and fixed in suitable journals, by which
means the head is adjusted. In addition to this adjusting screw a clamping
screw passing through the head and slot in the arm may be employed. The
said head carries the drill spindle, and is made with a boss on its front side
through which a vertical hole is bored to receive an adjustable spindle socket,
the latter sustaining a driving shaft and pinions, to which socket is attached a
swing bracket connecting with said shaft. This socket is held in said head
by means of a collar attached to the top of the said socket, whereby the latter
is free to turn on its own axis. By adjusting the socket the driving shaft
may be adjusted to either side of the drill spindle, thus facilitating the appli-
cation of power to the machine. This socket when adjusted is held by means
of set screws or other suitable device. The drill spindle passes through said
adjustable socket, and is raised or lowered by means of a vertical screw which
passes through a bracket formed upon the upper side of said head on the arm,
and is connected to the top of the spindle by means of pins inserted in the
side of the spindle, and passing into a groove cut in the end of the screw, the
latter being inserted a short distance in the top of the spindle, making a close
connection between the screw and spindle, so that when the whole is bored
through the metal the spindle cannot fall. The power to work the spindle is
applied through the agency of a pinion introduced in the lower end of the
spindle socket. The hub of this pinion is made of considerable length, and is
held in position in the lower end of said socket by means of keys set in the
latter on each side of the hub, so that their edges catch in a grove cut around
the hub to receive them, leaving said hub free to revolve in the socket. In
the drill spindle there is a feather seat cut along its entire length, in which
a feather set in the hub of the pinion matches, by which the spindle is driven.
Power is applied through an adjustable bar or shaft which is connected to the
driver by a universal joint, and at the opposite end with a device through
which power is communicated to this bar. This device consists of a main
horizontal spindle fixed in a suitable frame carrying cone pulleys, and upon
one end a bevel pinion matching into a pinion formed on the lower end of a
vertical spindle attached to the frame. Upon said vertical spindle is fixed a

page_text: swinging socket bracket, so arranged as to rotate freely. The said bracket
has upon its outer end a socket bearing to carry a horizontal shaft, on
the end of which is fixed a bevelled pinion which matches into a similar
pinion on the vertical spindle, by which means power is transmitted from
the cone pulleys to the aforesaid adjustable bar. The socket bracket is
held at the desired point on the vertical spindle by means of set screws.
Power may be applied to the adjustable shaft in a variety of ways, and said
device may be advantageously used for transmitting power to other kinds of
machinery.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Haseltine in the Great Seal Patent Office on the
12th November 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 12, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Civil Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of May, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said George Haseltine, Her special license that I, the said
George Haseltine, my executors, administrators, and assigns, or such others
as I, the said George Haseltine, my executors, administrators, or 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 PORTABLE DRILLING MACHINERY, PARTS OF WHICH ARE
APPLICABLE TO MACHINES FOR OTHER PURPOSES," a communication, upon the
condition (amongst others) that I, the said George Haseltine, my executors
or administrators, by an instrument in writing under my hand and seal, or
under the hand and seal of one of them, 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.

page_text: NOW KNOW YE, that I, the said George Haseltine, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying Drawings,
in which Figure 1 is a side elevation, Figure 2 an end elevation, Figure 3
is a top view of my machine, and Figure 4 represents the driving
apparatus..
The object of my Invention is to provide a machine of greater efficiency
and of more universal application, either as a hand or a power machine, for
the purpose of drilling metals. This object I accomplish by constructing a
machine in the following manner, that is to say :-I first make a base plate,
represented in the Drawing by A, and in it at right angles with the bottom
thereof I fit a shaft B, on which is fitted a clamp socket C, which socket is
secured by a screw D passing through lugs made on the back side of said
socket in the manner shown in the Drawing. On the front side of said socket
there is made a circular flange or head E, in which circular slots F are cut,
as shown in Figure 2. To this flange or head the arm G is bolted, a corre-
sponding circular head or flange H being made on the end of said arm. Upon
said arm I fit a moveable head I, on the back of which a nut is fixed to
project through the slot J in said arm; through this nut the screw L passes,
by which said head is moved to and fro on said arm, said screw being fixed
in suitable journals in said arm, in the manner screws are usually fixed for
similar purposes. In addition to the screw L for moving said head, there
may also be a screw M introduced in the back of said head through the slot
in said arm to clamp the head firmly after it has been adjusted, or the screw L
may be dispensed with, and the head moved and adjusted by hand, using only
the screw M to fix the head in the desired place. The head I is made with
a boss on its front side, through which a hole is bored vertically to receive an
adjustable socket N, on the lower end of which an arm Q is cast to carry the
driving shaft K and pinion P. Said socket is held in said head by means of
a collar screwed or pinioned to the top thereof, by which it is left free to turn
about its own axis. By these means the shaft K can be adjusted on either
side of the drill spindle, thus facilitating the application of power to the
machine by making it applicable from either direction. When said socket
has been adjusted to the desired position it is held by means of set screws a, a,
which pass through the boss of the head I, and lean against the said socket.
The head I also carries the drill spindle A' which passes through the socket N,
and is raised and lowered by means of a screw R, which passes through a

page_text: bracket S raised on the upper side of the head I, and is connected to the top
of the said spindle by means of pins inserted in the sides of the spindle in a
groove cut in the end of the screw, which is inserted a short distance in the top
of the spindle in the manner shown, making a close connection between the
screw and spindle, so that when the hole is drilled through, the spindle cannot
fall, disarranging the machine, and rendering it liable to be broken. The
power to drive the spindle is applied through the agency of the pinion O,
through which the spindle passes. The hub of said pinion is made of con-
siderable length, and is introduced in the lower end of the socket N, where
it is held by means of keys c, c, set in the socket on each side of the hub, so
that their edges catch in a groove cut around the hub to receive them, leaving
it free to revolve in the socket. In the drill spindle there is a feather seat d
cut along its whole length, in which a feather set in the hub of the pinion O
matches, by which the spindle is driven. The power to drive the machine is
applied to the adjustable bar T, which is connected to the driver K by means
of a universal joint in the manner shown. The power may be applied to the
shaft T in a variety of ways. But as an auxiliary to this machine, and to
facilitate the transmission of power to any machine of this nature, I have
contrived the driving apparatus shown by Figure 4, which constitutes a part
of my Invention; it consists of a frame U, and a set of cone pulleys V, with
a bevel pinion e on the main spindle to match in a corresponding pinion f on
the lower end of a spindle g, arranged in the frame at right angles with the
main spindle, and with a swinging socket bracket W arranged on the spindle g,
so as to swing freely around said spindle as a centre, said bracket arm having
a socket bearing in its upper end to carry a shaft i, on which a pinion b¹ is
fixed to match in a similar pinion h fixed on the spindle g, by which the power
is transmitted from the cone pulleys to the shaft T. The socket bracket W is
held in any desired position in the plane upon which it swings by means of
set screws k, k, which bear against the lower end of the arm that passes
through the head of the frame, and through which the spindle g passes, as
shown in dotted lines. It will be seen that by the use of the swinging arm
or bracket W, power can be transmitted to any machine within reach of the
apparatus, at either side of it, before or behind it, above or below it; an
illustration of this is shown in the application of the power to the drilling
machine on the Drawing.
The functions performed by the different parts of my machine may be
briefly stated thus:-By the base piece A the machine is secured to any
desired place by the use of bolts or cramps. By means of the socket C the

page_text: plane
drilling head I is raised, lowered, or swung around on a plane parallel with
the base, by which the operator can drill all around the standard anywhere
within reach of the arm G. By means of the adjustable joint formed by the
circular flanges E. H, the head I is thrown over in either direction on a
paralled with the shaft B, by which the operator can drill a hole on a plane
cutting diagonally through the shaft. By the use of the swinging socket
bracket N, the arm G can be swung around, and the bracket Q of the socket
can be adjusted backward or forward, so as to bring the shaft K on a line
with shaft T; thus making it unnecessary to change the position of the prime
mover. By the use of the adjustable shaft T the head I may be moved to or
from the driver without necessitating the use of different shafts. By the use
of the adjustable head I on the arm G greater facility is offered for drilling
holes anywhere within reach of the arm.
Machines consisting of the base piece A, standard B, socket C, arm G,
and head I, have been made and used before my Invention; but with the
arm G and head I differently constructed. The points of novelty making my
Invention are comprised in the construction of the head I, in the joint E, H,
in the arm, in the adjustable socket bracket N, and in the adjustable shaft T,
and the extent of novelty in these various parts will be found stated in the
following claims; that is to say, I claim as my Invention,―
First, making in the arm G of a portable drilling machine a joint, as at
E, H, so that the said arm can be thrown backward or forward on a plane
parallel with the standard shaft of the machine and diagonally across it, by
which the operator can drill a hole upon a plane cutting diagonally across the
said standard shaft.
Second, I claim constructing the adjustable head I of a portable drilling
machine, with the standard or bracket S raised thereon to carry the screw R,
and with a boss to receive the socket N and spindle A', and uniting the said
spindle and screw in a close connection, so that the spindle cannot fall when
the hole is through the metal or thing drilled.
Third, I claim in combination with the adjustable head of a portable
drilling machine, the swinging socket bracket N, Q, to facilitate the appli-
cation of power to the spindle, substantially as described.
Fourth, I claim in combination with the adjustable head of a portable
drilling machine, an adjustable universally-jointed shaft, as shown at T in the
accompanying Drawing.
Fifth, I claim in combination with the cone pulleys V and spindle g, the
swinging socket bracket W, to facilitate the transmission of power or motion

page_text: to said drilling machine, or to any other machine to which it may be
applicable.
In witness whereof, I have hereunto set my hand and seal, this Fifth
day of November, in the year of our Lord One thousand eight hundred
and sixty-four.
GEORGE HASELTINE. (L.S.)
