Year: 1816

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
BARKER, of Cottage Green, in the Parish of Camberwell and County of Surry,
Artist, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Sixth day of February, in the fifty-sixth year of His reign,
did give and grant unto me, the said Joseph Barker, my exors, adñiors, and
assigns, His special licence, full power, sole privilege and authority, that I,
the said Joseph Barker, my exors, adñiors, and assigns, during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "THE MEANS OF CONTINUING THE MOTION OF MACHINERY;" in
which Letters Patent there is contained a proviso obliging me, the said
Joseph Barker, under my hand and seal, to cause a particular description
of the nature of my said Invention, and in what manner the same is to be per-
formed, to be inrolled in His Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said recited
Letters Patent, as in and by the same, relation being thereunto had, may
more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Barker, do hereby declare that my said Invention is described and
ascertained in manner following, that is to say:-
My Invention of Means of Continuing the Motion of Machinery is for the

page_text: purpose of continuing a regular and constant motion and force to any
machinery, even though the prime mover or actuating force of the said machine
is not continuous or regular in its action. The means of effecting this is by
applying the prime mover or actuating force of the machine, which may be the
strength of men or animals, wind, water, or steam, to raise up certain detached
weights into an elevated trough or receptacle, in which a great number can
be contained and regularly and continually delivered out to certain other
machinery, of which the motion will be continued in an equable and regular
manner by the descent of the said weights, and the receptacle being made
large enough to contain a sufficient number of the said weights, they will act
constantly upon the machinery, and continue the motion thereof, even through
the action of the prime mover in raising the weights into the receptacle should
decrease or even cease altogether for a short time..
The manner of carrying my said Invention into effect is fully described in
the Drawings hereunto annexed, which contain two elevations of my means of
continuing motion to machinery, in which A, B, represent the elevated recep-
tacls for containing the weights, which are balls of a spherical figure. The
receptacle is formed like a trough, and should be made of a considerable
length to contain a great number of the said balls; it should be slightly
inclined towards the end B sufficiently to cause the balls to roll towards that
end where they are applied to the machinery. The balls are elivated or
raised up to the end A of the trough or receptacle by the power of the first
mover or actuating force which may be applied to raise up the balls in any
convenient manner. That which is represented in the Figure consists of
two vertical beams or planks C, C, in which are grooves to guide or direct a
cradle or frame D, which is adapted to receive one ball or weight at a time, or
more than one if it is preferred. To this frame or cradle a rope E is attached,
and
passes over a pulley F, and being drawn down by the force of men or
animals, or by the application of the powers of wind, water, or steam, will
draw up the ball or balls contained in the cradle from G to B, and there dis-
charge it or them into the end B of the trough or receptacle. For this
purpose the cradle is made to hang upon pivots, and has hooks projecting from
it which catch upon pins at the end of the trough B, when the cradle is
drawn up, and this oversets the cradle, and discharges the contained ball or
balls into the trough or receptacle A, B, where they remain until they are
wanted for continuing the motion of the machinery to which my Invention is
applied. The cradle is then lowered down to fetch up another ball or balls.
The manner of applying the force of men to pull down the rope E, and raise up
the balls into the receptacle A, B, is evident. When the force of horses or

page_text: other animal is applied for that purpose, the rope must be conducted over
another pulley near the ground, to make the draft horizontal, or nearly so.
When the power of wind, water, or steam is to be applied to this purpose,
the rope must be made to coil round a barrel or windlass, which is to be
turned round by the force of the windmill, water wheel, or steam engine, until
the weight is wound up and raised to the intended height. The motion of the
barrel is then to be disengaged to suffer the cradle to descend to fetch up
another ball, or more than one, as may be preferred. The disengagement of
the machinery may be effected by an endless strap, and live and dead pullies,
or by a clutch box, or by other means known and in use for similar purposes,
and two sliders C, C, and cradles D, may be applied each to raise up a ball
alternately into the said receptacle A, B, the one being made to ascend as the
other descends, which may be effected by winding the ropes which draw up
the cradles in opposite directions round the same barrel.
The means by which the weights so elevated are made to continue the motion
of any machinery to which my Invention may be applied is also represented in
the same Drawing. H and I are two vessels over which an endless chain is
extended, having buckets or cradles K, K, K, attached to it at proper dis-
tances to receive the balls or weights as they roll from the end B of the trough
or receptacle A, B; then several balls can be applied at once to the cradles of
the endless chain on one side of the wheels H, I, whilst there are no balls in
the cradles on the opposite side of the chain; because, as the cradles for the
balls come to the lower part of the wheel I, the cradles incline so as to let
the balls roll out into a trough M, which has a slight slope to convey the balls
towards the cradle D, by which they are elevated again to the trough A, B.
To prevent the balls issuing more than one at a time from the end B of the
trough A, B, a slider or shuttle a is applied, so that it detains the ball from
falling into the cradles of the endless chain until it is lifted up, which is done
by means of a lever wand rod b, b, descending to the lower part of the machine,
where it is connected with a second lever d, whieh the ball strikes the instant it
has quitted the lower part of the machine. By this means, the instant that
one ball quits the machine from below another is admitted from B into the
upper cradle of the chain which will be ready to receive it, for the purpose of
continuing the motion, which this Invention will do as long as the trough B
contains any balls. The continuous motion thus given to the wheel II may be
communicated by cog wheels or other known means to the machinery of which
the motion is to be continued by means of my Invention. The said machinery"
may be for grinding corn, spinning cotton, slitting iron, and all other
useful operations to which the power of machinery can be applied. To regu-
late the velocity of the motion a governor or flying balls, such as is used in a

page_text: steam engine, may be applied to my machine. For this purpose a bevelled or
toothed wheel o, Fig. 2, is fixed on the end of the axis of the upper wheel H of the
endless chain K, and its teeth give motion to a pinion h, fixed upon a vertical
axis h, k, at the top of which two pendulum rods k, l, k, l, are joined, and are
thus made to revolve with the axis h, k, at the same time that they are at
liberty to fly out from the centre by the action of their centrifugal force.. This
motion acts by two rods m upon a slide n, which slides freely up and down
upon the square part of the axis k, l, above k, and gives motion to a lever n, o,
which, by a communicating rod p, and lever or crank 7, causes a gripe or
break R, to bind or press round the circumference of a wheel W, which is
fixed upon the axis of the upper wheel H of the endless chain. The manner
in which this gripe is caused to act is as follows:-A lever r, s, is connected
with the break R of the wheel, and loaded with a weight t, which tends
always to depress the ends s of the lever, and draw the break R round the
wheel W, so as to cause a friction and retard the machine. The weight t
slides upon the lever r, s, with a roller, and is moved by the rod v communi-
cating with the crank 2 and lover n, o, of the governor. By this means, when
the machine revolves more quickly than is intended, the balls 1, 1, fly out and
slide the weight t further from the center of the lever r, s, so that it acts with
more force upon the gripe R until it retards the motion to its intended velocity.
When the machine works at its intended velocity, the weight t is slided so
near to the center of the lever r, s, that its weight will be wholly borne up by
a fixed bar w, upon which it slides with a roller; and as the bar w is fixed
in an inclined position, it takes off the bearing of the weight from the
lever, s, and then the weight does not act at all upon the lever to close
the gripe R round the wheel W; but if the velocity of the machine accelerates,
then the flying out of the balls 1, 1, draws the weight t away from the center of
the lever, s; and as the bar w is placed inclined the weight t quits the
bearing of the fixed bar w, and bears upon the ends of the lever with a
sufficient force to close the gripe R, and retard the machine to its intended.
velocity.
The form and dimensions of my said machine may be varied and adapted
to the circumstances governing the same, which variations and adaptations
workmen conversant with work of a similar nature can devise and execute.
In witness whereof, I, the said Joseph Barker, have hereunto set my
hand and seal, this Fifth day of August, in the year of our Lord One
thousand eight hundred and sixteen.
JOSEPH (L.S.) BARKER.
