page_text: LETTERS PATENT to James Hundy, of Birmingham, in the County of
Warwick, Timber Dealer, for the Invention of "A NEW OR IMPROVED
INSTRUMENT OR APPARATUS FOR RAISING WEIGHTS, FOR MOVING HEAVY.
BODIES, AND FOR OTHER LIKE PURPOSES."
Sealed the 18th August 1865, and dated the 24th February 1865.
PROVISIONAL SPECIFICATION left by the said James Hundy at the
Office of the Commissioners of Patents, with his Petition, on the
24th February 1865.
I, JAMES HUNDY, of Birmingham, in the County of Warwick, Timber
5 Dealer, do hereby declare the nature of the said Invention for "A NEW OR
IMPROVED INSTRUMENT OR APPARATUS FOR RAISING WEIGHTS, FOR MOVING HEAVY
BODIES, AND FOR OTHER LIKE PURPOSES," to be as follows:-
The said instrument or apparatus consists of a cylindrical roller of a length
equal to several times its diameter. At or about the middle of the roller, and
in a plane at right angles to its axis, one or more arms or levers are fixed by
means of which a rotary motion may be given to the roller. An endless band
or loop of cord is fixed at or about its middle to one or more of the arms or
levers, and the opposite ends of the loops are fixed respectively to the body to
be moved and a fixed body. By giving a rotary motion to the roller by means.
5 of the arms or levers the loop of cord is wound on the roller and the said loop

page_text: of cord shortened. The body to be moved is drawn in the required direction by
the shortening of the loop. The winding of the loop takes place at its middle,
and both halves of the loop are wound and shortened simultaneously. The arms
or levers on the working of the instrument pass between the opposite sides of
the loop, and the instrument may be fixed at any point by means of rings
sliding loosely on the cord. By sliding one or more of these rings towards the
roller, and passing it over the end of one of the arms or levers, the motion of
the arm or lever is prevented, and the instrument fixed in the position to which
it has been brought. The power of the instrument may be made greater or
less by altering the ratio between the diameter of the roller and the length of
the levers. I make the said instrument or apparatus of wood or metal, or
partly of wood and partly of metal. For small instruments I prefer to make
the roller of wood with a transverse hole at its middle through which a rod of
iron can be passed to form two arms or levers. The instrument thus made is
very portable and may be carried together with the loop of cord in the pocket.
Instead of fixing the levers at the middle of the roller they may be fixed at
the ends with the same or nearly the same effect.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Hundy in the Great Seal Patent Office on the
-23rd August 1865. _
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HUNDY, of Birmingham, in the County of Warwick, Timber Dealer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of February, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said James Hundy, Her special licence that I, the said James
Hundy, my executors, administrators, and assigns, or such others as I, the
said James Hundy, 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 Ire-
land, the Channel Islands, and Isle of Man, an Invention for "A NEW OB IM-
PROVED INSTRUMENT OR APPARATUS FOR RAISING WEIGHTS, POR MOVING HEAVY
BODIES, AND POR OTHER LIKE PURPOSES," upon the condition (amongst others)

page_text: that I, the said James Hundy, my executors or administrators,. by
an instru-
ment in writing under my, or their, or one of their hands and seals, shoulds
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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Hundy, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following.
statement thereof, that is to say :-
The said instrument or apparatus consists of a cylindrical roller of a length
equal to several times its diameter. At or about the middle of the roller,. and.
in a plane at right angles to its axis, one or more arms or levers are fixed, by
means of which a rotary motion may be given to the roller. An endless band
or loop of cord is fixed at or about its middle to one or more of the arms or
levers, and the opposite ends of the loops are fixed respectively to the body to
be moved and a fixed body. By giving a rotary motion to the roller by means
of the arms or levers the loop of cord is wound on the roller and the said loop
of cord shortened. The body. to be moved is drawn in the required direction
by the shortening of the loop. The winding of the loop takes place at its
middle, and both halves of the loop are wound and shortened simultaneously.
The arms or levers on the working of the instrument pass between the
opposite sides of the loop, and the instrument may be fixed at any point by
means of rings sliding loosely on the cord. By sliding one or more of these
rings towards the roller, and passing it over the end of one of the arms or levers
the motion of the arm or lever is prevented, and the instrument fixed in the
position to which it has been brought. The power of the instrument may be
made greater or less by altering the ratio between the diameter of the roller
and the length of the levers. I make the said instrument or apparatus of wood
or metal, or partly of wood and partly of metal. For small instruments I
prefer to make the roller of wood with a transverse hole at its middle, through
which a rod of iron can be passed to form two arms or levers. The instrument
thus made is very portable, and may be carried together with the loop of cord
in the pocket. Instead of fixing the levers at the middle of the roller, they
may be fixed at the ends with the same or nearly the same effect, and instead
of employing one cord to form the two loops, two separate cords may be used.
Having explained the nature of my Invention, I will proceed to describe
with reference to the accompanying Drawing the manner in which the same
is to be performed.

page_text: Figure 1 represents in plan, and Figure 2 in side elevation, one form of my
Invention in which a single band or cord is employed.
The instrument or apparatus consists of a roller a, made by preference of
wood, but the said roller may however be made of metal. At or about the
middle of the roller two arms or levers c, d, are fixed, the said arms consisting
of a single rod or two rods of iron passed through a transverse hole in the
roller a.
An endless band or rope is fixed at or about its middle to one of the
arms or levers c, d, so as to form two loops marked e, f, situated on either side
the roller a. One of the loops e or f is fixed to the weight to be raised or body
to be moved, and the other of the said loops is secured to a fixed body. The
securing of the endless band or rope to the instrument is effected by twisting
the middle of the band or rope round one of the arms c or d, as represented.
The loops e, f, having been fixed respectively to the body to be moved and a
fixed body, the roller a is rotated by means of the arms or levers c, d, and the
endless band or cord wound upon the roller a, the arms or levers c, d, passing
between the opposite loops e, f, on the rotation of the said arms. The band
or cord is wound at its middle in opposite directions upon the roller a, and the
loops e, f, are thereby shortened simultaneously. The weight or body to be
raised or moved is thus drawn rapidly in the required direction by the shorten-
ing of the loop to which it is connected and that secured to the fixed body, the
roller a as the loops e, f, are shortened approaching nearer to the fixed body.
The instrument may be fixed at any point by means of bands
loosely on the loops e, f; one of these rings is marked g.
ring g towards the roller, and passing it over the end of the arm or lever c,
the motion of the arms or levers is prevented, and the instrument fixed in the
position to which it has been brought. The power of the instrument may be
made greater or less by altering the ratio between the diameter of the roller a
and the length of the arms or levers c, d.
or rings sliding
By sliding the
Figure 3 represents in plan an arrangement of my Invention in which each
of the loops is made of a separate cord or band, and the motion of the roller
is effected by arms or levers at the ends of the roller. A is the roller, having
arms h at its ends for rotating it. In the middle of the roller is an arm i similar
to one of the arms of the roller, Figures 1 and 2, to which the band or cord k
is secured to form one of the loops of the instrument. The other loop 1 of the
instrument is formed by fixing the free ends of a cord or band in the grooves
m, m, at the ends of the roller a. By turning the roller a by the arms or
levers h, the loops k and are wound upon the roller in opposite directions,
and the said loops simultaneously shortened, as herein-before described with
respect to Figures 1 and 2. Instead of preventing the rotation of the roller a

page_text: when the instrument is required to be fixed by means of a sliding ring 9 passed
over the arm c, as in the arrangement represented in Figures 1 and 2, the
same object may be effected by means of a rigid bar or rod o passed between
the arm i and the loop k, as represented in Figure 3. In order to prevent the
said bar or rod o from being removed by a sudden jerk from between the arm i
and loop k it is secured by two loops of cord p which are hung loosely on the
roller a.
Instead of effecting the rotation of the roller by arms or levers a winch at
the end of the roller may be used for that purpose, as illustrated in Figure 4,
where the winch is marked n.
The uses to which my Invention can be advantageously applied are the
raising of weights, the felling of trees, and the raising and moving of heavy
bodies generally.
In felling trees by means of my Invention, in the absence of any fixed
support, a short tripod driven into the ground at a convenient distance from
the tree to be felled may be used as a fixed support.
Having now described the nature of my Invention, and the manner in which
the same is to be performed, I wish it to be understood that I do not limit myself
to the precise details herein described and illustrated in the Drawing, as
the same may be varied without departing from the nature of my Invention;
but I claim as my Invention, a new or improved instrument or apparatus
for raising weights, for moving heavy bodies, and for other like purposes, the
parts of which are constructed and arranged essentially in the manner herein-
before described and illustrated in the accompanying Drawing.
In witness whereof, I, the said James Hundy, have hereunto set my
hand and seal, this Twenty-first day of August, in the year of our Lord
One thousand eight hundred and sixty-five.

Clerk to George Shaw,
