AN IMPROVED PORTABLE DRILLING MACHINE
Year: 1864

page_text: LETTERS PATENT to Benjamin Fowler, junior, of Liverpool, in the County
of Lancaster, Ironfounder, for the Invention of "AN IMPROVED PORTABLE
DRILLING MACHINE."
Sealed the 16th September 1864, and dated the 18th March 1864.
PROVISIONAL SPECIFICATION left by the said Benjamin Fowler at
the Office of the Commissioners of Patents, with his Petition, on the
18th March 1864.
I, BENJAMIN FOWLER, junior, of Liverpool, in the County of Lancaster,
Ironfounder, do hereby declare the nature of the said Invention for "AN
IMPROVED PORTABLE DRILLING MACHINE," to be as follows:-
My Invention consists in combining in a portable form any of the arrange-
ments of mechanism employed in fixed vertical drilling machines with a treadle
or foot motion.
In carrying the Invention into effect I support the crank shaft and parts
thereto attached, such as the fly wheel, the treadle or footboard, the driving.
pulley, or other frictional or coupling means which may be employed for
transmitting the motion upwards from such crank shaft to the operating tool,
on or by the framework; and use the top of such framework as the table to
bear or carry the articles under treatment in the machine. The framework
resembles that of a portable turning lathe, but there is secured thereto, and
rising upwards from the table thereof, an arm inverted like in shape for
carrying the vertical tool carrier and other working parts which convey the

page_text: transformed motion of the treadle to the tool carrier and the tool or drill.
Bevel wheels can conveniently be used for transmitting motion from the
treadle crank shaft, and herein-after I explain that modification of my Inven-
tion. I place one bevel wheel on the treadle crank shaft, and gear it with
another second bevel wheel secured on a vertical shaft, which passes upwards,
and reaches to the bend or elbow of the inverted L-like arm above named.
This vertical shaft has collars thereon, which rest on bearings in or projecting
from the framework to keep it in- position, and near its the vertical shaft's
upper end is secured another third bevel wheel, made to gear with a fourth
bevel wheel fastened on a horizontal shaft supported by or from the upper and
horizontal portion of, the inverted L-like arm. The motion of this horizontal
shaft may be communicated by an ordinary bevel wheel fitted to slide on a
feather to the vertical tool carrier. In use the motion is from the treadle
crank shaft to the vertical shaft, thence to the horizontal shaft, and from this
latter to the vertical tool carrier and the tool or drill."
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Benjamin Fowler in the Great Seal Patent Office on the
17th September 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
FOWLER, junior, of Liverpool, in the County of Lancaster, Ironfounder, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of March, 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 Benjamin Fowler, junior, Her special licence that I, the said
Benjamin Fowler, junior, my executors, administrators, and assigns, or such
others as I, the said Benjamin Fowler, junior, my 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 "AN IMPROVED PORTABLE DRILLING MACHINE," upon the condition (amongst
others) that I, the said Benjamin Fowler, junior, my executors or administrators,
by an instrument'in writing under iny, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,

page_text: 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 I, the said Benjamin Fowler, junior, 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 (that is to say):
My Invention consists in combining, in a portable form, any of the arrange-
ments of mechanism employed in fixed vertical drilling machines with a treadle
or foot motion.
In carrying the Invention into effect I support the crank shaft and parts
thereto attached, such as the fly wheel, the treadle or footboard, the driving
pulley, or other frictional or coupling means which may be::employed for
transmitting the motion upwards from such crank shaft. to the operating tool,
on or by the framework, and use the top of such framework, as the table to
bear or carry the articles under treatment in the machine. The framework
resembles that of a portable turning lathe, but there is secured thereto, and
rising upwards from the table thereof, an arm invented L like in shape for
carrying the vertical tool carrier and other working parts, which convey the
transformed motion of the treadle to the tool carrier and the tool or drill.
The accompanying Sheet of Drawings shew, by Fig. 1, a side elevation,
and by Fig. 2 a front elevation, of an improved combined portable vertical
machine, which I have found to answer well. The same letters indicate like
parts in both views.
a denotes the framework, the table of which is marked a¹, and the L-like
arm a²; b, treadle crank shaft; c, cranks; d, rods connecting the levers and
footboard e; f, fly wheel; 9, vertical running shaft, with collars h resting on
the framework; i, double bevelled wheels, free to slide on their respective
shafts, and capable of being moved by their levers ;, that a faster or slower
speed may be obtained by gearing the small wheel of the crank shaft with the
large wheel of the vertical shaft, or by gearing the large wheel of the crank
shaft with the small wheel of the vertical shaft; k, bevelled wheel on the
vertical shaft gearing with bevelled wheel 2 on the horizontal running shaft m;
this shaft m carries another bevelled wheel n, which gears with similar wheel o,
through which the vertical tool carrier p is free to slide; q shews & hand
wheel the axis thereof being screwed to give pressure in the usual way.
Having now set forth the nature of and referred to the several parts of
a machine constructed according to my said Invention, I would have it under-
stood that I do not confine myself to any particular means or arrangement of

page_text: parts for conveying motion from the crank shaft, as friction pullies, cams,
pullies, and straps, and other mechanical equivalents might be variously
employed; nor do I confine myself to any particular arrangement of parts for
giving pressure, as levers, weights, and other means could be employed.
What I claim as my Invention is, combining in a portable form a treadle
or foot motion with mechanism suitable for conveying and giving rotary
motion to the tool carriers in vertical machines.
In witness whereof, I, the said Benjamin Fowler, junior, have hereunto
set my hand and seal, this Fifteenth day of September, in the year of
our Lord One thousand eight hundred and sixty-four.
BENJAMIN FOWLER, JUNIOR. (L.S.)
