IMPROVEMENTS IN MORTISING MACHINES
Year: 1875

page_text: LETTERS PATENT to Henry Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer,
for the Invention of "IMPROVEMENTS IN MORTISING MACHINES.”—A
communication from abroad by Auguste Eugène Adrien Pihet,
of Paris, in the Republic of France.
Sealed the 4th January 1876, and dated the 7th July 1875.
PROVISIONAL SPECIFICATION left by the said Henry Edward Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 7th July 1875.
I, HENRY EDWARD NEWTON, of the Office for Patents, 66, Ohancery
5 Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MORTISING
MACHINES," to be as follows:—
PROVISIONAL SPECIFICATION left by the said Henry Edward Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 7th July 1875.
I, HENRY EDWARD NEWTON, of the Office for Patents, 66, Ohancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MORTISING
MACHINES," to be as follows:-
The object of this Invention is to raise or lower the tool carrier of
mortising machines, as may be required to suit the varying thicknesses of
the material to be operated upon.

page_text: In carrying out the Invention the tool-carrier slides on a hollow
cylindrical column which is firmly attached to a base plate. A vertical
semicircular recess is made the whole length of the column, and one
or more lugs on the tool carrier slide freely in this recess. The required
up and down motion is given to the tool carrier by means of a screw 5
which passes through the lug or lugs on the tool carrier, and motion is
imparted to this screw by a fly wheel and set of gearing.
"
The mechanism for giving the up and down motion to the mortising
tool is of the ordinary construction, but inasmuch as the position of the
tool carrier is not always the same, it is necessary somewhat to modify 1
the driving mechanism. To this end two fixed pullies are mounted, one
at either end of the vertical column, and an endless band is passed round
these pullies, and thence round two pullies mounted one above the
other on studs on the tool carrier. Motion is communicated to the
lower of the fixed pullies from any suitable motor. By this means it 1
will be seen that whatever the position of the tool carrier, the arrange-
ment of the driving mechanism will remain the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Edward Newton in the Great Seal Patent
Office on the 7th January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
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 Soventh day of July, in the year of our 2
Lord One thousand eight hundred and seventy-five, in the thirty-ninth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Henry Edward Newton, Her special licence
that I, the said Henry Edward Newton, my executors, administrators,
and assigns, or such others as I, the said Henry Edward Newton, 8
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

page_text: carrier, the arrangement of the driving mechanism will remain the
same.
=
In the accompanying Drawing, Fig. 1 is a side elevation of the
improved machine which may be used for operating upon either metals
or hard wood; Fig. 2 is a sectional plan view of the same, the section
being taken in the line 1, 2, of Fig. 1.
.
Fig. 3 is a diagram representing the endless strap for driving the
working parts of the tool carrier in whatever position it may be with
reference to the table on which the work is placed.
On the base or foundation A of the machine is raised a hollow vertical 1
cylindrical:column B, upon which is mounted the tool carrier O and all
the mechanism connected. therewith; D is the table upon which the
article to be operated upon is fixed, and which by means of the
mechanism shown at Figures 1 and 2 may be moved laterally, longi-
tudinally, or in a circular direction. In the column B and from top to 1
bottom thereof is made a longitudinal recess 6 to receive a vertical
.screw V, which passes through a nut or female screw c on the tool
holder O; this screw V, the lower end of which rests in a socket, carries
at its upper end a toothed wheel F which gears into a pinion ƒ on the
shaft G, to which motion is imparted by the hand wheel E, and bevil 2
gearing e, e¹...
It will be seen from this arrangement of parts, that if it be desired to
alter the distance between the surface of the table D and the under part
of the tool holder or carrier O, it will only be necessary to turn the hand
wheel E in the required direction and thus actuate the screw V which 2
will move in a vertical direction the nut or female screw c of the tool
carrier. At whatever height the tool holder or carrier O may be placed
its working parts will always be properly actuated by the endless
strap X, Fig. 3, which passes round the two pullies y, y', the distance
of which from each other never varies. This endless strap passes over 8
the pulley z, and under the pulley 2¹, both of which are mounted on the
tool carrier O, and therefore rise and fall with it.
I
.
From the foregoing description it will be understood that the cutting
tool will always receive its up-and-down motion, whatever may be its
distance above the table D. This arrangement of parts therefore very 8
much facilitates the operation of the machine for shaping, mortising,

page_text: and slotting. In fact instead of being inconvenienced by the want of
space between the table and tool carrier, as is now the case, there
will be sufficient distance between these parts to admit of operating
with the greatest facility upon all sides of a piece that may require to be
mortised or shaped.
Having now described the Invention of "Improvements in Mortising
Machines," which has been communicated to me by my foreign corre-
spondent, and having explained the manner of carrying the same into
effect, I claim as the Invention secured to me by Letters Patent as
aforesaid, the mode herein set forth of mounting the tool carrier C, so
that whatever its distance may be from the table on which the article to
be operated upon is placed, the working parts of the tool carrier may be
properly driven as above described.
In witness whereof, I, the said Henry Edward Newton, have here-
unto set my hand and seal, the Sixth day of January, One
thousand eight hundred and seventy-six.
