IMPROVEMENTS IN MORTICING MACHINES
Year: 1876

page_text: LETTERS PATENT to John Mark and George Wilson, both of Leeds, in the County
of York, for the Invention of "IMPROVEMENTS IN MORTICING MACHINES."
PROVISIONAL SPECIFICATION left by the said John Mark and George
Wilson at the Office of the Commissioners of Patents on the 16th June 1876.
JOHN MARK and GEORGE WILSON, both of Leeds, in the County of York. "IM-
PROVEMENTS IN MORTICING MACHINES."
Our improvements have reference to morticing machines worked by hand.
We dispense with the rack and pinion which is usually employed for transmit-
ting the required motion from the hand lever.
The framework is of ordinary construction, and at the back of the slide carrying
the cutter spindle is provided a nut through which is passed a regulating screw,
this being mounted in suitable bearings at the upper part of the framework. By
this arrangement the slide carrying the cutter may be adjusted in a vertical direc-
tion. On the nut are provided trunnions or studs, on which are fitted so as to work
freely two connecting rods, between which at their other extremity in suitable
bearings is hung or carried the hand lever, in which bearings a radial movement can
be given thereto. This lever is made to act on the slide directly over the cutter
spindle, whereby when the lever is put in motion by the attendant a direct action
is obtained. When the slide is being adjusted by means of the adjusting screw the
hand lever being attached to the nut is moved or adjusted in the same direction.
The morticing tool may be reversed in the ordinary manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Mark and George Wilson in the Great Seal Patent Office on the
13th December 1876.

tained. When the slide is being adjusted by means of the adjusting screw the hand

And in order that our Invention may be more completely understood reference is
given to the accompanying Sheet of Drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Figure 1 is a side elevation; Figure 2, a front elevation; Figure 3, a part back
elevation; and Figure 4, a plan looking at the top.
a is the framework, which may be of ordinary construction, as shown; c is the
cutter carrier in which is provided the cutter spindle d of ordinary construction;
e is a regulating or adjusting screw mounted in suitable bearings f and provided
with a nut g. On the nut y are provided the trunnions or studs h, on which aro
fitted so as to work freely the connecting rods i, between which at their end j is
hung or carried the hand lever k, provided with suitable bearings, as shewn, in
which bearings a radial movement can be given thereto. The lever k is jointed to
the slide cat, and made to act upon it directly over the cutter spindle d, whereby
when the lever is put in motion by the attendant a direct action is obtained.
When the slide c is adjusted by means of the adjusting screw, the hand lever k
being attached to the nut g by means of the connecting rods i, is adjusted in the
same direction. After the adjustment has taken place the nut g may be fixed in
position on the upper part of the framework b by means of the nuts m, which are
screwed on to the ends of the trunnions ; these being passed through the slot n in
upper part of the framework b, this slot n being of sufficient length to allow for
adjustment.
The other parts of the machine are of ordinary construction.
Having now described the nature of our said Invention, and shown by Drawings
how the same may be carried into practice, we would have it understood that we
do not limit ourselves to the exact details or configuration of the various parts we
have explained and shewn, as the same may of course be varied or modified with-
out in any way departing from the nature of our Invention; but what we do claim
and desire to be secured to us by Letters Patent is-
First. The arrangement and application of screw e and adjustable nut g in com-
bination with connecting rods i and hand lever k, whereby the cutter spindle d may
be adjusted and worked, substantially as herein set forth.
Second. The combination of the above with the other parts shown on the Draw-
ing hereunto annexed forming the machine, substantially as herein set forth.
In witness whereof, I, the said John Mark, for myself and on behalf of the
said George Wilson, have hereunto set my hand and seal, this Eleventh day
of December, in the year of our Lord One thousand eight hundred and
