page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
HOLDEN, of Stafford Street, in the Parish of St. Mary-le-bone, in the County
of Middlesex, Gentleman, send greeting.
WHEREAS His present Majesty King George the Third, in and by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Twentieth day of February last,
for Himself, His heirs and successors, did give and grant unto me, the said
Richard Holden, my exors, admors, and assigns, His especial licence, full
power, sole privilege and authority, that I, the said Richard Holden, my
exors, adñiors, and assigns, and every of them, by myself and. themselves,
or by my or their deputy or deputies, servants or agents, or such others as
I, the said Richard Holden, my exors, adñññors, or assigns, should at any
time agree with, and no others, from time to time and at all times hereafter
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within that part of His Majesty's United Kingdom
of Great Britain and Ireland called England, His Dominion of Wales, and
Town of Berwick-upon-Tweed, and also in all His Majesty's Colonies and
Plantations abroad, my "MACHINES FOR PRODUCING ROTATORY AND PENDULOUS
MOTION IN A NEW MANNER;" in which said Letters Patent there is contained
a proviso that if I, the said Richard Holden, should not particularly describe
and ascertain the nature of my said Invention, and in what manner the same
is to be performed, by an instrument in writing under my hand and seal, and
cause the same to be inrolled in His Majesty's High Court of Chancery,
within six calendar months next and immediately after the date of the said

page_text: recited Letters Patent, that then the same Letters Patent, and all liberties
and advantages whatsoever thereby granted, should utterly cease, determine,
and become void, as in and by the same Letters Patent, reference being
thereunto had, will more fully appear.
NOW KNOW YE, that I, the said Richard Holden, in compliance with
the said proviso, do hereby declare that the following statement under my
hand and seal, and the annexed Drawings, do particularly describe and ascer-
tain the nature of my said Invention, and the manner in which the same is
to be performed, viz* :-
My Invention of Machines for Producing Rotary and Pendulous Motion
in a New Manner consists in communicating the power of the screw or
inclined planes to a beam or lever, so as to produce the alternate rising and
falling of the ends of the beam or lever, and then, by means of a rod con-
nected with one end of the beam or lever, and the crank of a fly wheel, the
rotatory motion is produced, see Figure 1, and by means of a similar rod
connecting a lever, (set in motion by means of a screw or inclined planes as
above described), with a pendulum, the pendulous motion is produced, sco
Figure 4. In giving such a motion to the beam or lever, the nut or box
may revolve and the screw rise and fall, or the screw may revolve and the
nut or box rise and fall. In the machines shewn by the annexed Drawings,
the screws revolve, and the boxes rise and fall. Those machines may be
worked by manual or horse labor, by wind, water, steam or other powers
by which machinery is put in motion.
Figure 1 of the Drawing is a view of a machine for producing the rotatory
motion, in which A is the crank or handle; B, the fly wheel fixed upon the
axis C, C; upon the same axis C, C, are also fixed the two vertical bevel
cog wheels D, D, each wheel having teeth only half way round. The cogs
of these vertical wheels work alternately into the horizontal bevel cog
wheel E, (which is fixed to one of the spindles K, K.) whose diameter is
larger than that of the vertical wheels, and has two teeth omitted (one
omission only appears in this Drawing) for the purpose of more easily
receiving the cogs of the vertical wheels, so that when all the teeth of one
of the vertical wheels D has passed through the cogs of E, the other wheel D
presents its teeth to the horizontal wheel at the place where the tooth is
omitted, and gives it a retrogado movement; upon the lower part of the
spindles K, K, are two cog wheels F, F, of equal diameter, which work
into one another, turning alternately according to the motion of the wheel E;
and at the upper part of the spindles K, K, are screws G, G, which turn with
the spindles K, K, in opposite directions, and the sliding boxes H, H, made

page_text: with female screws, are raised and lowered by the alternate movement of the
screws G, G. These boxes H, H, are connected to the beam Qat I, I,
by the two arms L, L, and cause the beam Q to oscillate, and thus commu-
nicates by the rod R and crank S the rotatory motion to the fly whicel T,
and so on, to other machinery; M, being the framework or standard with
parts broken away to exhibit more plainly those parts of the machinery
otherwise hidden; N, the carriage of the beam; and Q, the working beam.
For the better understanding the connection of some parts of the machine
not visible in Figure 1, I refer to Figures 2 and 3.
.
Figure 2 exhibits an end view of the machine, where F is one of the cog
wheels before mentioned; K is one of the spindles moving in the sockets
or cups P, P; G, one of the screws fixed upon the said spindle. These
screws are three inches and an half in diameter, and cut so that I would
move six inches if G were to make an entire revolution. The screws, how-
ever, may evidently be varied according to the power and motion required.
H is one of the sliding boxes with a female screw, and is raised and lowered
by the alternate motion of the screw G; J, J, are the side plates; L, L, arc
two arms bolted or otherwise fastened to the box H, and connected so as to
move easily by the pinions I, I, to the beam Q; N, N, the carriage of the
beam.
Figure 3 shews the plan or horizontal view of one of the boxes H, H,
where W, W, are holes for the arms L, L, to pass, attaching them to
the box H by a screw or other means; X; X, grooves for the side
plates J, J, to slide in.
The machine for producing the pendulous motion is shewn by the Drawing
Figure 4, in which A is the crank or handle; B, the fly wheel fixed upon
the axis C, C; upon the same axis C, C, are also fixed two vertical bevil
cog wheels D, D, each wheel having teeth only half way round. The cogs
of those vertical wheels work alternately into the horizontal bevel cog
wheel E, fixed to the spindle K, and whose diameter is larger than that of the
vertical wheels, and has two teeth omitted (one omission only appears in this
Drawing) for the purpose of more easily receiving the cogs of the vertical
wheels, so that when all the teeth of one of the vertical wheels D has passed
through the cogs of E, the other wheel D presents its teeth to the horizontal
wheel at the place where the tooth is omitted, and produces a retrogade move-
ment; E is upon the axis or spindle; K, the spindle moving in sockets or
cups P, P, turning alternately, according to the motion of the wheel E, and at
the upper part of the spindle is a screw G that raises and lowers the sliding
box H, made with a female screw; L is one of two arms bolted or otherwise

page_text: fastened to the box H, and connected so as to move easily by the pinion I
to the beam Q, which causes the lever to oscillate, and then, by the rod R,
connected with the pendulum S, produces the pendulous motion. For further
elucidation, I refer to Figures 2 and 3.
I have described the above as convenient examples of machines for pro-
ducing rotatory and pendulous motion by communicating the power of the
screw or inclined planes to a beam or lever, but it would be impossible to
describe every variety of machine which might be constructed for this purpose,
for it must be evident that there are various other modes of giving motion
to the screw or box, and also various other modes of conveying the power of
the screw to the beam or lever, and which will readily suggest themselves
to persons at all conversant with mechanics.
i
It is to be observed, that I do not claim as my Invention the use of bevel
cog wheels, or of the fly wheels, or of the crank, or the mode of producing
alternate rotatory motion by means of the cog wheels with teeth only half
way round, but I use these with other things as convenient instruments for
assisting in communicating the power of the screw or inclined planes to the
beam or lever, and from thence to the other parts of the machine.
In witness whereof, I have hereunto set my hand and seal, the
