IMPROVEMENTS IN MEANS OR APPA- PROVISIONALATION
Year: 1875

page_text: LETTERS PATENT to William Stewart James Horne Munro, of
Nettlebed, near Henley-on-Thames, in the County of Oxford; Doctor
of Medicine, for the Invention of "IMPROVEMENTS IN MEANS OR APPA-
PROVISIONAL SPECIFICATION left by the said William Stewart
James Horne Munro at the Office of the Commissioners of
Patents, with his Petition, on the 23rd June 1875.
I, WILLIAM STEWART JAMES HORNE MUNRO, of Nettlebed, near
Henley-on-Thames, in, the County of Oxford, Doctor of Medicine, do.
hereby declare the nature of the said Invention for "IMPROVEMENTS, IN
MEANS OR APPARATUS FOR FACILITATING THE CUTTING OR FELLING OF STANDING
TIMBER," to be as follows:-

page_text: endway motion is given to this saw by chains or bands, connected each
by one end to opposite ends of the saw, and at the other ends to a wheel
or such like reciprocating motion operated on by a lever and horse or
other power.
The saw is borne to the object to be cut either by its opposite ends
being connected to the ends of another endless chain or band, which
chain or band is also passed round a suitable pulley and which pulley is
acted on by a chain or band so as to be drawn by a weight or lever or by
other suitable pressure. Or the saw is borne to the object to be cut by
the chains or bands which move the saw in its horizontal course, being
operated on by a lever or other power which would produce suitable
pressure.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Stewart James Horne Munro in the
Great Seal Patent Office on the 30th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
STEWART JAMES HORNE MUNRO, of Nettlebed, near Henley-on-Thames,
in the County of Oxford, Doctor of Medicine, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of June, in the year
of our 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 William Stewart James Horne
Munro, Her special license, that I, the said William Stewart James
Horne Munro, my executors, administrators, and assigns, or such others
as I, the said William Stewart James Horne Munro, 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 "IMPROVEMENTS IN
MEANS OR APPARATUS FOR FACILITATING THE CUTTING OR FELLING OF STANDING
TIMBER," upon the condition (amongst others) that I, the said William

page_text: Stewart James Horne Munro, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
scals, 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 Scal 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 Stewart James Horne
Munro, 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 thereof, that is to
say:
-
To facilitate the cutting or felling of standing timber a saw is sup-
ported to move endwise in a horizontal direction, and the desired
endway motion is given to this saw by chains or bands connected cach
by one end to opposite ends of the saw, and at the other ends to a wheel
or such like reciprocating motion operated on by a lever and horse or
other power.
The saw is borne to the object to be cut cither by its opposite ends
being connected to the ends of another endless chain or band, which
chain or band is also passed round a suitable pulley and which pulley is
acted on by a chain or band so as to be drawn by a weight or lever or by
other suitable pressure. Or the saw is borne to the object to be cut by
the chains or bands which move the saw in its horizontal course being
operated on by a lever or other power which would produce suitable
pressure.

But that the Invention may be fully understood I will by the aid of
anving Drawings proceed to describe manne nussund h..

page_text: c is a chain which passes partly round the driving pulley d, as well as
also partly round the tension and guide pulleys e and f, and is connected
.at its ends respectively to the opposite ends of the saw bat b¹, b', and
these points ¹ are in the line of the cut of the saw teeth to facilitate
the cutting by the saw.
'The reciprocating motion to the saw may be variously obtained. As
shown the driving pulley d is supported in the frame y and it is
operated so as to receive a reciprocating rotary motion for the reci-
procating motion to the saw in the following manner: -h, h, arc sockets
applied to the plate h' and capable of receiving arms to be operated
by horses or other cattle, or by manual labor travelling in the
circle indicated by the red line i to produce rotary motion to the
plate which is supported for that purpose by the frame g. The
plate ¹ is also formed with an internal ring of teeth, which by taking
into the teeth of the pinion ; in its rotation give motion to that
pinion j. This pinion j is affixed to a shaft or axis which is sup-
ported to be capable of freely revolving in bearings carried by the
frame g and has affixed to it another toothed wheel, the teeth of
which take into the teeth of the pinion affixed on the shaft ≫, which
is also supported to revolve in bearings carried by the frame y and
carries the plate m, in which is affixed the adjustable crank pin m'
to receive one end of the crank rod n, the other end of which is con-
nected to a stud d' standing up from the pulley d. 'g', g', are bearing
wheels to the frame g, by which it may be readily wheeled about from
one locality to another, and g² are sockets to receive handles ³ to
facilitate such transit. The pulley e is by other pulleys, chains, or
bands, or by other suitable means connected to the trunks of other trees
o, p, or to other suitable holding means with capability for adjustment
to the varying position of the saw b during its cutting operation. 'The
pulley is carried by a slight frame or moveable holder. The position
of this pulley f in acting on the chain c tends not only to reduce
friction on the chain c but also to draw the saw into the trunk to be
cut; but this pressure, as well as the tension on the saw, may be effected
by the application of a lever or weight or other suitable means ; ¡9',-9*,
are guide pulleys.
Having thus described my Invention and means which I adopt in
carrying the same into effect, I would have it understood that I do

page_text: not confine myself to the precise arrangements of parts referred to so
long as the peculiar character of my Invention be retained, substantially
as described.
In witness whereof, I, the said William Stewart James Horne
Munro, have hereunto set my hand and scal, this Twenty-
ninth day of October, in the year of our Lord One thousand
cight hundred and seventy-five.
