Year: 1827

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
STANHOPE HOLLOND, of the City of London, Esquire, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Nineteenth day of December, in the eighth year of
His reign, did, for Himself, His heirs and successors, give and grant. unto
me, the said Thomas Stanhope Hollond, His especial licence, that 'I, the
said Thomas Stanhope Hollond, my executors, administrators, and assigns,
or such others as I, the said Thomas Stanhope Hollond, my executors,
administrators, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein ex-
pressed, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, and also in all
His said Majesty's. Colonies and Plantations abroad, my Invention of
"CERTAIN COMBINATIONS OF MACHINERY FOR GENERATING AND COMMUNICATING
POWER AND MOTION, APPLICABLE, TO. THE PROPELLING OF FIXED MACHINERY, AS
ALSO FLOATING BODIES, CARRIAGES, AND OTHER LOCOMOTIVE MACHINES AND IMPLE-
MENTS;" in which said Letters Patent is contained a proviso obliging me, the
said Thomas Stanhope Hollond, by an instrument in writing under my hand
and seal, particularly to describe and ascertain the nature of my said Inven-
tion, and in what manner the same is to be performed, and to cause the same
to be enrolled in His said Majesty's High Court of Chancery within six calendar

main wheel A, being on one common axis with the zigzag, will be driven
in the same direction, carrying the machine which it supports upon its axis
along with it; and if the zigzag be then extended again to its greatest length
the wheel F not being able to retrogade, the wheel G will then move forward
in the direction of the arrow, followed by the main wheel A carrying the
machinery with it as before. Thus it will be seen that by the alternate con-
traction and extension of the zigzag a continuous progressive movement of the
main wheel A will be obtained; and it now only remains to explain how that
alternate motion is given to the zigzag, in order to show the complete action
of the engine. For this purpose I attach the bars f, J, turning on pivots or
joints, to the upper part of zigzag, as here shewn, and connect the head of
these bars at r with the lever L. In fact the pivot of the bars at r forms
the centre on which the lever L turns. The short arm of the lever is fastened
to a cord running over a pulley on the common axis aforesaid, to the
weight W which is suspended from the lower part of the zigzag by the bars
or pivots t, 1, and the long arm of the lever is supposed to be held down
in its horizontal position by manual exertion or any adequate power. Now,
it is evident that if the long arm of the lever L be allowed to rise, the
weight W will descend, and at once contract or draw the zigzag into its
shortest position; then if the long arm of the lever L be again pulled down
to its horizontal position, the short arm of the lever L will lift the weight W,
and press with a corresponding force upon the top pivot of the bars f, J; so
that in fact the action of the lever L transfers the power of the weight W from
the top to the bottom of the zigzag at pleasure, and thus alternately contracts
and extends the zigzag, thereby producing a continuous forward motion of the
main wheel A, as before mentioned, and by this means the whole machine
is put in motion. K is a fly wheel connected by the rod M with the pivot
at r by means of a crank on its axis, which crank admits of the rise and fall
of the bars f, J, and is of course adjusted to assist that motion; N, N, are two
guide levers, one at each end of the machine, to turn the wheels F and G
when required; Q is a platform fastened upon the conimon axis S to carry
the load which is intended to move by this machine; and R is one of the
uprights to carry the fly wheel K set upon the platform.
In the Drawing marked No. 2, Figure 1 is a view of the same side of
my said Invention as was exhibited in the last Figure, but shewing the
appearance of it when the long arm of the lever L. is up, and the weight W
down, which it will be seen has contracted the zigzag to it- shortest position.

page_text: The same letters of reference are used to denote similar parts in both the
Drawings and all the Figures, so that if any part of the Figures on Drawing
No. 2, are not clearly understood, a reference to the description of the
Drawing No. 1 will explain it.
Figure 2 in this Drawing is an end view of my said Invention, with such
parts of the nearer end removed as would cause the remainder to be more
clearly seen for the purposes of explanation; R, R, and O, O, are the uprights
to carry the axis of the fly wheels K, K; there are slots in the uprights O, O,.
to admit of the axis 1 working up and down by the motion of the lever L; this
axis is in fact the pivot on which the upper parts of the bars f, J, work;
X, Y, is the traverse bed of the train or end wheels F, F, through which the
perch runs on friction rollers to make it traverse freely; Z, Z, are four
clicks or pauls, two being on cach nave and set in opposite directions, and
falling into ratchets to prevent the wheels F, F, from turning both ways
at the same time, and of course the way which the wheels turn, and con-
sequently the way which the machine moves, will depend upon which paul is
allowed to act in its ratchet.
Having now described my Invention as applied to locomotive purposes, it is
only necessary to observe that when it is to be applied to moving fixed
machinery, it is only necessary to remove the main wheel A and let the common
axis frest on a fixed bearing, while the pauls and rachets on the naves of the
wheels F and G, as also the platform, must be removed.
Now whereas it is evident that the mode of applying my said Invention
must depend upon the particular nature of the work that it is required to
perforin, and the relative proportions also of its various parts may be varied
to meet similar necessities. But whereas I claim as my Invention the
combinations of machinery which constitute the machine or engine represented
by the Drawings annexed and herein-before particularly described, and such
variations on the same as are herein-before mentioned, and are necessary
to make it applicable to the moving of fixed machinery as well as locomotive
engines. And such my Invention being, to the best of my knowledge and
belief, entirely new, and never before used within that part of His said
Majesty's United Kingdom of Great Britain and Ireland called England,
His said Dominion of Wales, or Town of Berwick-upon-Tweed, nor in any
of His said Majesty's Colonics or Plantations abroad, I do hereby declare
this to be my Specification of the same, and that I do verily believe this
my said Specification doth comply in all respects fully and without reserve
or disguise with the proviso in the said herein-before in part recited Letters

page_text: Patent contained; wherefore. I hereby claim to maintain exclusive right
and privilege to my said Invention.
In witness whereof, I, the said Thomas Stanhope Hollond, have here-
unto set my hand and seal, the Nineteenth day of June, in the year
of our Lord One thousand eight hundred and twenty-eight.
AND BE IT REMEMBERED, that on the Nineteenth day of June, in the
year of our Lord 1828, the aforesaid Thomas Stanhope Hollond came before
our said Lord the King in His Chancery, and acknowledged -the Specifi-
cation aforesaid, and all and every thing therein contained and specified, in
form above written. And also the Specification aforesaid was stamped accord-
ing to the tenor of the Statute made for, that purpose.
Inrolled the Nineteenth day of June, in the year of our Lord One
thousand eight hundred and twenty-eight.
