page_text: LETTERS PATENT to William Edward Newton, of the Office of Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "IMPROVEMENTS IN DRILLING MACHINES."-A communication
from abroad by Warren Lyon, David Van Gelder Isaacs, Alexander
M°Andrew, and Samuel Wann, all of the City and State of New York,
in the United States of America.
Sealed the 3rd November 1866, and dated the 7th June 1866.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 7th June 1866.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN DRILLING MACHINES," to be as
follows:-
This Invention relates to drilling machines in which the working parts and
the table or bed which supports the work are attached either to an upright
post or pillar of timber or other material, or to an upright standard of iron.
The feeding of the drill is produced by a weight applied directly to the drill
stock, which may be driven either by means of a crank handle or by the
application of power to a band wheel from which the motion is transmitted by
means of bevil gearing. The pressure of the weight is regulated by an
adjustable counterpoise lover connected with the drill stock and operated upon

page_text: by another lever, which also serves the purpose of raising the drill stock and
drill to a suitable position above the work, to permit the work to be placed
and adjusted upon and removed from the table or bed plate on which the
drilling is performed.
The second part of the Invention consists in the attachment of the drill stock
to the upright post or standard of the machine by means of a bracket, which
with the two bearings in which the drill stock works are all cast in one piece,
and which is bolted to the post or standard at a suitable height, such bracket
and bearings constituting a convenient means of putting up the drill stock and
adjusting it for work, either when attached to a wooden post or pillar which
forms a portion of the building in which the machine is used, or to an
independent post or standard.
The third part of the Invention consists in furnishing the adjustable table
or bed plate upon which the work is placed to be drilled with a fixed jaw and a
sliding jaw which works in fixed guides or cleats on the table or bed plate,
and which is adjustable by means of a screw for the purpose of clamping
the articles to be drilled between the two jaws, and thereby holding them
firmly during the drilling operation.
The operation consists, finally, in constructing the standard, which carries the
working parts of the machine, and the adjustable table or bed plate on which
the work is supported, with a suitable recess for the introduction of large
articles while supported on the table or bed, and thereby adapting the machine
for the drilling of large articles without having the drill stock or the table or
bed plate set out at a great distance from the face of the standard.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office on
the 7th December 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, 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 Seventh day of June, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Edward Newton, Her special licence that I, the said William
Edward Newton, my executors, administrators, and assigns, or such others as

page_text: I, the said William Edward Newton, 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 "IMPROVE-
MENTS IN DRILLING MACHINES," being a communication from abroad, upon
the condition (amongst others) that I, the said William Edward Newton,
executors or administrators, by an instrument in writing under my, 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 per-
formed, 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 I, the said William Edward Newton, do hereby
declare the nature of the 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 Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention relates to drilling machines in which the working parts and
the table or bed which supports the work are attached either to an upright
post or pillar of timber or other material, or to an upright standard of iron.
The feeding of the drill is produced by a weight applied directly to the drill
stock, and the pressure of this weight is regulated by an adjustable counter-
poise connected with the drill stock by a system of levers, which also serve
the purpose of raising the drill stock and drill to a suitable position above the
work, so as to permit the work to be placed and adjusted upon and removed
from the table or bed plate on which the drilling is performed, and it is in
this counterpoise and system of levers and their connections that the first part
of the Invention consists.
The second part of the Invention consists in the attachment of the drill stock
to the upright post or standard of the machine by means of a bracket; which
with the two bearings in which the drill stock works are all cast in one piece
which is bolted to the post or standard at a suitable height, such bracket and
bearings constituting a convenient means of putting up the drill stock and
adjusting it for work, either when attached to a wooden post or pillar, which
forms a portion of the building in which the machine is used, or to an
independent post or standard.
The third part of the Invention consists in furnishing the adjustable table
or bed plate upon which the work is placed to be drilled with a fixed jaw and

page_text: a sliding jaw, which works in fixed guides or cleats on the table or bed plate, and
is adjustable by means of a screw for the purpose of clamping the articles (to
be drilled) between the two jaws, and thereby holding them firmly during the
drilling operation.
The operation consists, finally, in constructing the standard which carries the
working parts of the machine, and the adjustable table or bed plate on which
the work is supported, with a suitable recess for the introduction of large
articles while supported on the table or bed, and thereby adapting the machine
for the drilling of largo articles without having the drill stock or the table or
bed plate set out a great distance from the face of the standard.
In the accompanying Drawing Fig. 1 is a front elevation of a hand-drilling
machine, the working parts and the work table or bed plate of which are
attached to an upright post or pillar which may form a part of the building,
in which the machine is placed, or it may be an independent post; Fig. 2 is a
side elevation of the same; Fig. 3 is a plan of the work table with the clamping
jaws and their appurtenances.
A represents the post or pillar supported on a suitable base B. These parts
may be of wood or metal. To the standard A a cast-iron bracket C is firmly
bolted; this bracket is cast with bearings a, a, in which the vertical drill stock
D is fitted and allowed to rotate freely, and also slide up and down; this
stock D is formed with a crank E for the purpose of turning it by hand, and
on the upper end of this stock there is a weight F, which is made in the form
of and serves as a fly wheel. By having the bearings a, a, of the drill stock
Don a cast-iron bracket C, as shewn, the drill stock may be easily put up
and adjusted in proper position for work; G is a swivel fitted to the upper
end of the stock D and connected by a link H to a lever I, the fulcrum pin
of which is in a bracket J firmly bolted to the post or pillar A. The rear end
of the lever I is connected by a link K to another lever L, the fulcrum pin of
which passes through the upper end of a bar M', the lower end of the latter
being secured by a pivot bolt c to a lug d attached to A. On the lever L
there is placed a sliding weight M, which may be secured at any desired point
by a set screw c. This arrangement permits the downward pressure of the
weight F on the stock D to be graduated as desired by adjusting tho weight
M on the lever L, nearer to or further from the latter. The lever L has a rod
N attached to it by a pivot f, and the lower end of this rod is beut in the form
of a hook g to catch under a bar h attached to the post A, so as to hold up
the stock D, when it is desired to elevate the drill free from the bed plate.
The drill O is fitted in the lower end of the stock D. The rod N has a curved
arm or handle i for actuating the levers to elevate the drill. P is the bed

page_text: plate or table on which the work to be drilled is placed. This plate or table
is attached to or fitted on a bracket Q, which is provided at its inner end with
a eye or tube j, the latter being fitted on a vertical fixed shaft R, the ends
of which have lugs & attached to them, these lugs being bolted to the post A.
The bracket Q may be secured higher or lower on the shaft R, as required, by
a set screw l. The bed plate has two parallel cleats m, n, on its under side,
the inner surfaces of which cleats are bevilled or inclined to form a dovetail
to slide upon the outer part of the bracket Q, which has inclined sides to
conform to the bevilled surfaces of the cleats m, m. By this means the bed
plate P may be readily adjusted upon and removed from the bracket Q. On
the
upper surface of the bed plate P there is a vertical projection or fixed
jaw u made with a notch o at its front side, and there are also two parallel
cleats p, p, on the upper surface of the bed plate, between which a slide R¹ is
fitted and works. This slide R also has a notch q in its face side (see Fig.),
and is operated by a screw S, and inade to clamp square bars or other small
articles to be drilled in an upright position, a hole, being made in P for the
bars or other articles to pass through. The notches o, q, insure the proper
entering of the bars or other articles. The bed plate P may be properly
adjusted in relation to the drill by turning the bracket Q either to the right or
to the left on its fixed shafts R, or raising or lowering it as may be desired.
In drilling plates an ordinary flat bed plate may bo used.
Fig. 4 is a side elevation of a power-drilling machine, the work table or bed
plate P and working parts of which are all supported by an independent
cast-iron standard A', in the front of which there is a recess A³ above the
table P, for the reception of any large article which may be placed upon the
table P.
Fig. 5 is a front elevation of the machine shewn at Fig. 4. All those parts
of these Figures which are not herein-after referred to correspond with the
parts of the machine shewn at Figures 1 and 2, and are lettered in a similar
manner. In this machine the drill stock D consists of a straight shaft, which
is fitted with a feather and groove to a bevil wheel T, which turns in the upper
bearing a in such manner that it may be prevented from moving up or down,
while tho drill stock is capable of sliding longitudinally and vertically within
it, but compelled to rotate with it. This bevil wheel gears with a bevil wheel
U, which is fast on a horizontal shaft V fitted to rotato in fixed bearings in
or on the standard A', and furnished with a pulley W which receives a belt
running on a pulley X on a horizontal driving shaft Y, mounted in suitable
bearings attached to the lower part of the standard for the purpose of driving
the drill by a steam engine or other motor. The driving shaft Y is also

page_text: furnished with a pulley Z to receive a driving belt. This machine has the
table P cast with or permanently attached to the bracket Q.
A machine in other respects like that shewn in Figures 1 and 2 ma be
só modified as to driven by power like that shewn in Figures 4 and 5, and
a machine in other respects like the latter may be so modified as to be driven
by hand like that shewn in Figures 1 and 2.
Having now described the Invention that has been communicated to me as
aforesaid, and having explained the manner of carrying the same into effect, I
claim as the Invention secured to me by Letters Patent as aforesaid,―
First, the arrangement as berein shown and described of the levers I, L,
drill stock D with the weight F, and the counterpoise M on the lever L, and
the rod N for the purposes specified.
Second, the use of the bracket C with bearings a, a, attached, in combina-
tion with the drill stock D and its concomitant parts, as herein shewn and
described.
Third, the projection u, and cleats p, p, on the face or upper side of the
bed plate P in combination with the slide R', screw S, and the adjustable
bracket Q to which the bed plate is attached.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, the Third day of December, in the year of our
Lord One thousand eight hundred and sixty-six.
