IMPROVED APPARATUS FOR OBTAINING AND APPLYING MOTIVE POWER
Year: 1857

page_text: LETTERS PATENT to Horatio Bunting, of Colchester, in the County of
Essex, Seed Grower, for the Juvention of "IMPROVED APPARATUS FOR
OBTAINING AND APPLYING MOTIVE POWER."
PROVISIONAL SPECIFICATION left by the said Horatio Bunting at the
Office of the Commissioners of Patents, with his Petition, on the
14th December 1857.
I, HORATIO BUNTING, of Colchester, in the County of Essex, Seed Grower,
do hereby declare the nature of the said Invention for "IMPROVED APPARATUS
FOR OBTAINING AND APPLYING MOTIVE POWER," to be as follows:-
This Invention consists in an arrangement of mechanism whereby the
oscillating motion of a weighted beam, produced by the vibration of a lever
by hand, is transferred to a shaft and converted into rotatory motion for driving
machinery and for other motive purposes.
A beam, similar to an ordinary scale beam, is mounted upon a suitable axis
or pivots and weighted at each end. This beam is provided at the centre with
a short lever projecting upwards, and with a pendulum or weighted lever pro-
jecting downwards, both being rigidly connected to the beam. Near to each end
of the beam is a connecting rod, each connecting rod being coupled by means
of a bell-crank lever and link to a crank upon a shaft, which is placed below
the centre of the beam, and upon this shaft is keyed a fly-wheel. This shaft
is also furnished with a third crank, which communicates by means of a rod to

page_text: a crank above the beam, the said last-named crank being connected by a link
and sliding rod to the upright lever at the centre of the weighted beam.
Motion is first communicated by hand to this crank, by means of a lever or a
winch handle, causing the weighted beam to oscillate, and by means of tho
levers and links transmitting rotatory motion through the cranks to the fly
wheel shaft below.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Horatio Bunting in the Great Seal Patent Office on the
14th June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HORATIO
BUNTING, of Colchester, in tho County of Essex, Seed Grower, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
ne, the said Horatio Bunting, Her special licence, that I, the said Horatio
Bunting, my executors, administrators, and assigns, or such others as I, tho
said lloratio Bunting, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVED
APPARATUS POR OBTAINING AND APPLYING MOTIVE POWER," upon the condition
(amongst others) that I, the said Horatio Bunting, my executors or admi-
nistrators, 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 Horatio Bunting, do hereby declare the
nature of my 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, that is to say :-
It consists of certain mechanical arrangements and combination of parts,

page_text: Figure 1 is a back elevation of the apparatus, and Figure 2 a side elevation
of the same; Figures 3 and 4 are views of the details; Figure 5 shews an
elevation of the apparatus, the arrangement of the parts being somewhat
different from the last, but the same principles being retained.
In Figure 1, a, a, is a large vibrating or oscillating beam or balance, deli-
cately centred upon knife-edge or other pivots, and supported upon the
upright pillar b. Attached to and nicely suspended from the centre of this
beam, so as to oscillate freely when actuated by the oscillations of the latter,
is a large and heavy pendulum c; near the extremities of the beam are
attached the transmitting rods d, d, which transmit their motion through the
bent levers e, e, (which are supported on the pillars f, f, and rotate round the
point g,) to the rods h, h, attached to the cranks k, k, of the main axlo m; n is
the fly-wheel mounted upon one end of the axle; and o, a toothed driving
wheel from which motion is transmitted to the machinery to be driven.
Motion is communicated at first to the machine by hand (or by steam or
animal or other power, applied at the crank handles p, p, on the axes of the
wheels r, r; the connecting rods s, &, attached to the extremities of the beam
or balance at the one end, and on the rim of wheels r, r, at the other. It
will be seen that when the wheels r, r, are made to revolve, the effect will be
to cause the beam to oscillate, or to be alternately elevated at one end and
depressed at the other; the pendulum attached to the centre of the beam will,
therefore, by the motion of the latter, be caused to oscillate, and from the law
of its motion give additional force to the ation of the beam; this will be
conveyed through the transmitting rods d, d, the bent levers e, e, and the
cranks rods h, h, to the main axle, and from thence by means of the driving
wheel to the machinery to which the apparatus is applied.

page_text: Figure 3 shews the elevation of the crank axle, and Figure 4 the same
elevation of the pillars supporting the bent levers c, c.
In Figure 5 the arrangement, as will be seen, is somewhat different; tho
balance a is put in motion on its centre by means of the power applied over
the centre of oscillation at a', and by means of the rod attached to the periphery
of the wheel r, which is made to rotate; in this case weights w, w, are fixed
at the extremities of the balance or beam, and motion is conveyed through
the transmitting rods d, d, and the bent levers c, e, to the crank rods h, h, on
the axis of the wheel n. The mode of producing action in this apparatus is
exactly similar to that above described.
Having now described my Invention, and how it is to be carried into effect,
I wish it understood that what I claim, and wish secured by the before in part
recited Letters Patent, is, the arrangement of the beam or balance in combi-
nation with the action of the pendulum, together with the combination of
parts for producing the action of the apparatus, substantially as described in
the Specification, and illustrated in the Drawings appended thereto.
In witness whereof, I, the said Horatio Bunting, have hereunto set my
hand and seal, this Fourteenth day of June, in the year of our Lord
One thousand eight hundred and fifty-eight.
HORATIO BUNTING. (L.S.)
