page_text: LETTERS PATENT to William John Cunningham, of North Crescent,
Bedford Square, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED IN DRILLING AND
"
Sealed the 12th October 1866, and dated the 13th April 1866.
PROVISIONAL SPECIFICATION left by the said William John Cunningham
at the Office of the Commissioners of Patents, with his Petition, on the
13th April 1866.
I, WILLIAM JOHN CUNNINGHAM, of North Crescent, Bedford Square, in the
County of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED IN DRILLING AND ORNAMENTING
METAL, WOOD, AND OTHER SIMILAR SUBSTANCES," to be as follows:-
The Invention has for its object improvements in means or apparatus employed
in drilling, and ornamenting metal, wood, and other similar substances. For
this purpose I employ apparatus which may be conveniently applied to the bed
plate of a lathe, or to the table of a circular saw or other suitable apparatus,
from which rotary motion may be readily obtained; or the apparatus may be

page_text: applied to a frame, and by means of a treadle or other suitable means receive
rotary motion by a strap or band from a suitable shaft.
The apparatus consists of a rod or shaft, on the lower end of which is
mounted a pulley receiving rotary motion in any suitable manner; to the axis
of the pulley a drill, rose cutter, or other suitable rotary cutter may be
applied. To the upper end of the rod or shaft is connected by a link or other
suitable means a lever handle by which the operator may raise or lower the
rod or shaft in order to bring the tool in position to operate on the work or
remove it therefrom. The rod or shaft is guided in its up-and-down motion
in a casting, to a projection from which the axis of the lever handle is affixed;
this casting is so constructed as to be readily fixed either to a slide or bar
with capability of adjustment thereon. When employing such apparatus in
combination with a lathe I fix it to a bar or slide carried by a bar fixed to
the bed plate of the lathe in such manner that the drill or other formed cutter
may be capable of being shifted to different parts of a table upon which the
material to be drilled or ornamented is fixed, such table being capable of
turning in a horizontal plane around its axis or of being inclined thereto.
The apparatus will then receive rotary motion from a pulley fixed on a shaft
or axis mounted between the lathe head and back centre of the lathe, or by
other suitable means. Fences or other suitable means are applied to the
table in order to fix the work in any desired position thereon.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William John Cunningham in the Great Seal Patent Office
on the 13th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
JOHN CUNNINGHAM, of North Crescent, Bedford Square, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of April, 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 John Cunningham, Her special licence that I, the said William-
John Cunningham, my executors, administrators, and assigns, or such others
as I, the said William John Cunningham, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time

page_text: 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 Inven-
tion for "IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED IN DRILLING AND
5 ORNAMENTING METAL, WOOD, AND OTHER SIMILAR SUBSTANCES," upon the condition
(amongst others) that I, the said William John Cunningham, my 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 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 William John Cunningham, 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 thereof, that is to say:-
The Invention has for its object improvements in means or apparatus
employed in drilling and ornamenting metal, wood, and other similar substances.
For this purpose I employ apparatus consisting of a rod or shaft, on the lower
end of which is mounted a pulley receiving rotary motion in any suitable
manner; to the axis of the pulley a drill, rose cutter, or other suitable rotary
cutter may be applied. To the upper end of the rod or shaft is connected, by
a link or other suitable means, a lever handle by which the operator may
raise or lower the rod or shaft in order to bring the tool in position to operate
on the work or remove it therefrom. The rod or shaft is guided in its up-and-
down motion in a casting, to a projection from which the axis of the lever
handle is affixed. This casting is so constructed as to be readily fixed either
to a slide or bar with capability of adjustment thereon.
When employing such apparatus in combination with a lathe I fix it to a bar
or slide carried by a bar fixed to the bed plate of the lathe in such inanner that
the drill or other formed cutter may be capable of being shifted to different parts
of a table upon which the material to be drilled or ornamented is fixed, such
table being capable of turning in a horizontal plane around its axis or of
being.inclined thereto. The apparatus will then receive rotary motion from
a pulley fixed on a shaft or axis mounted between the lathe head and
back centre of the lathe, or by other suitable means. Fences or other suitable
means are applied to the table in order to fix the work in any desired position
thereon.

page_text: And in order that Dу invention may be more funy understood and readily
carried into effect, I will proceed, aided by the accompanying Drawings, more
fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view, partly in section, of means or apparatus for drilling
and ornamenting metal, wood, and other similar substances constructed
according to my Invention. a, a, is a rod or shaft, which is guided correctly.
in its motion to and from the work by passing through a hole formed in the
casting b, as shown. At the lower end of the rod or shaft a is mounted
a. pulley c. the axis c¹ of which is fixed with capability of revolving in
the interior of the rod or shaft a, as shown, or by other suitable means.
The lower end of the axis c' is formed to receive a drill, rose cutter, or other
suitable rotary cutter. The upper end of the rod or shaft a is pin-jointed to
the links d, which by pin-joint is connected to a lever e. The lever is pin-
jointed to the standard f, as shown, and by it the necessary motion is given at
the times desired to the rod or shaft a, and consequently to the drill or other
cutter employed to cause it to approach to or recede from the work. By means
of a hole b¹ in the casting b the apparatus may be fixed to a rod or bar or
otherwise as desired.
The apparatus above described may be conveniently applied to the bed
plate of a lathe, or to the table of a circular saw or other suitable apparatus,
from which rotary motion may be readily obtained; or the apparatus
may be applied to a frame, and by means of a treadle or other suitable
means receive rotary motion by a strap or band from a suitable shaft.
Figure 2 is a plan, Figure 3 a front view, and Figure 4 a sectional end
view, shewing the mode in which the drilling or ornamenting apparatus' may
be used in combination with a lathe. The drilling or ornamenting apparatus
(which is marked with similar letters of reference to those employed in
Figure 1) is fixed, as shown, to the rod or bar g with capability of adjustment
thereon; this bar is carried by the bar h with capability of turning in a hole
formed in the boss h', whilst the bar h is fixed to the bed i, i, of the lathe, as
shown at Figures 2 and 4. The bar h is also provided with other bosses h, h
forming bearings, in either of which the axis k may be placed as required. At
the upper part of the axis k is a boss or bearing to receive the horizontal
shaft or axis formed on or fixed to the boss or bearing 1, in which the axis m¹
of the bed or table m is fixed with capability of turning therein. The axis m
fixed, as shown, in the boss or bearing 1, or it
of the bed or table m may be

page_text: may be mounted in either of the bosses or bearings h³, h³, by these means
facility is given for turning the bed or table m in any desired position around
its axis m', and in a horizontal or inclined plane, whilst such bed or table mis
also rendered capable of being moved in the arc of a circle struck from the
centre of either of the bosses or bearings h³, ; the various parts supporting
the, bed or table m may be fixed in any desired position by means of the
screws n. If desired, the bosses h' and h³ may be divided as shown, and by
spring clicks or stops o the amount of motion given to the various parts may
be readily regulated. The under surface of the bed or table m may be formed
into a dividing plate into any of the holes of which a spring peg p is capable
of entering, whilst the upper surface of the table may be provided with
"fences
in order to fix the work in any desired position thereon. Rotary.
motion is communicated to the drill by the gut or band
from the pulleys q
mounted on the axis q³, which is supported between the lathe head and back
centre of the lathe, and caused to turn with the spindle of the lathe head; or
the axis may be mounted in bearings at the back of the lathe, and receive
rotary motion in any suitable manner. If desired, a compound slide rest may
be fixed to the bed or table m, as shown by the red lines in Figure 3, and
screws may be applied (as will be well understood) in such manner as to give
motion to the axes around which the bed or table is moved instead of giving
motion to them by hand. The axis g¹ of the rod or bar 9 may also be
provided with a screw in such manner as to give the desired amount of
motion thereto, extra guide pulleys would however be required for the gut or
band q¹ when it is desired to give motion to the rod or bar 9 around its axis g¹ ;
or such band q¹ may be formed of india-rubber so as to permit the required
motion to be given to the rod or bar carrying the drilling or ornamenting
apparatus. It will be readily understood that although I have described the
apparatus shown in Figures 2, 3, and 4 as applied to the bed of a lathe,
such apparatus may be applied to other machines or to a suitable framing.
Having thus described the nature of my said Invention, and the means I
have found to answer in carrying the same into effect, I would have it
understood that I do not confine myself to the precise details herein shown and
described, but what I do claim is,-
First, the peculiar arrangement or combination of apparatus for drilling
and ornamenting metal, wood, and other similar substances, substantially as
shewn and described in respect to Figure 1 of the Drawing annexed.
And, secondly, I claim the peculiar arrangement and combination of means
whereby the apparatus shown at Figure 1 may be readily applied to a lathe

page_text: or other suitable machine, substantially as shown and described in respect to
Figures 2, 3, and 4 of the Drawing annexed.
In witness whereof, I, the said William John Cunningham, have hereunto
set my hand and seal, this Twelfth day of October, in the year of our
Lord One thousand eight hundred and sixty-six.
