TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
EMANUEL HARPUR and BENJAMIN BAYLIS, both of Weedon, in the County of
Northampton, Engineers, send greeting.
.
WHEREAS His most Excellent Majesty King George the Fourth did,
by His Letters Patent under the Great Seal of His United Kingdom, bearing
date at Westminster, the Eighteenth day of March, 1823, in the fourth year
of His reign, give and grant unto us, the said George Emanual Harpur and
Benjamin Baylis, our exors, adñors, and assigns, His especial licence, full
power, sole privilege and authority, that we, the said George Emanual Harpur
and Benjamin Baylis, our 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, and also in
all His Majesty's Colonies and Plantations abroad, our Invention of "A NEW*
METHOD OF IMPELLING MACHINERY;" in which said Letters Patent there is
contained a proviso that if we, the said George Emanual Harpur and Benjamin
Baylis, or one of us, shall not particularly describe and ascertain the nature of
our said Invention, and in what manner the same is to be performed, by an
instrument in writing under our hands and seals, or under the hand and seal
of one of us, 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'

page_text: of the said Letters Patent, that then the said Letters Patent, and all liberties
and advantages whatsoever thereby granted, shall utterly cease, determine,
and become void, as in and by the same, relation being thereunto had, will
more more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Benjamin Baylis, do hereby declare that the nature of our said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the Drawings hereunto annexed, and the following
description thereof (that is to say):-
Our Invention of "a New Method of Impelling Machinery" consists of
certain arrangements of mechanism to be attached to an overshot water
wheel, by means of which pumps are worked that supply the wheel with
water, and thereby a very considerable mechanical power is obtained. The
Drawing hereto annexed shews our mode of arranging certain spur wheels,
pinions, levers, fly wheels, connecting rods, and pumps, and of actuating them
by the revolution of a bucket water wheel. a, is a reservoir of water, con-
taining about three tuns, that is supposing the wheel to be twenty feet diameter;
b, b, are two pumps, the rods of which, c, c, are worked by means of the
leverage obtained above; d is a cistern, intended to receive the water delivered
from the pumps by the small lateral pipes c, e; from the bottom of this cistern
the water flows through a valve on to the periphery of the wheel, and by
filling the buckets on the descending side of the wheel causes it to revolve
upon its axis. In order to put this machinery in action the reservior a must
be first filled with water, as above stated, and likewise the upper cistern d;
the pumps must also be charged with water, when the machinery will be in a
state for action. On opening a valve in the bottom of the cistern & the water
will be permitted to flow into the bucket immediately under it, which will
cause that side of the wheel to descond by its gravity; the other buckets will
also become filled as they pass under the valve, the increased weight of which
will cause the wheel to revolve upon the same principle as the ordinary bucket
water wheel. To the axle or shaft of this bucket wheel a toothed or spur
wheel is fixed, which turns a pinion g; on the shaft of this pinion g another
toothed wheel is fixed, which actuates two pinions, i and h, upon the
shafts of two fly wheels 7 and m. By this train the fly wheels are made to
revolve with great velocity and to regulate the motion of the machinery. n,n,
are two sweep rods, respectively connected by their joints to the fly wheels
1 or m; the lower ends of these rods are jointed to levers o, o, which vibrate
upon fulcrum pins or pivots p, 1; at the reverse ends of these levers o, o, the
"

page_text: start rods 7, 9, are respectively attached by joints, from whence they pass up to
the top lever r, and are jointed thereto; thus by the revolution of the bracket
wheel all these levers and wheels are put in motion. In order to produce a
sufficient stoke of the pumps, it is necessary that the lever r should traverse
as well as vibrate; this is effected by fixing the lever r to a roller s, and causing
the roller to traverse over a curved bearing or bed t. The action of the roller
is to be guided by two arms v, which carry the fulcrum or pivot of the tra-
versing lever 1. To the pump rods c, c, chains u, u, are attached, which pass
over anti-friction rollers w, w, and round the traversing roller s, to which those
extremities are confined; a portion of the roller s, and also the bed t has teeth,
for the purpose of preventing the roller from slipping as it traverses. Thus,
by the action of the lever r, moved as above described by the fly wheels, levers,
and rods, the pump rods are alternately raised, and if the gravity of the rods
be not sufficient to depress them again in the pump barrels, the lever r will
strike against their crutched heads, and force them down. By this arrange-
ment of mechanism we are enabled not only to raise a sufficient quantity of
water to work the bucket wheel, but do also obtain a surplus power, which
may be exerted at the axle of the large wheel for the working of any descrip-
tion of machinery requiring a first mover.
Though we have considered it necessary to describe various mechanical con-
trivances well known to engineers, in order to render our Invention perfectly
understood, yet we do not mean the whole of these to be considered as claimed
by us, but rest our title of Invention in the traversing lever, and the means by
which it is made to produce an extended lift and depression of the pump rods,
knowing that various attempts have been made to effect this object, but which
could not be accomplished without the traversing of the lever above described.
We forbear giving a scale to our Drawing, as the dimensions of the parts
must be varied according to circumstances, and may be extended or contracted
in their disposition to produce any increase of power within the capability of
the machinery; on the other hand, if we should not wish to employ the whole
power which the machinery is capable of exerting, we permit a portion of the
water raised by the pumps to escape from the upper cistern by a waste pipe,
and to run down into the well.
In witness whereof, I, the said Benjamin Baylis, have hereunto set my
hand and seal, this Eighteenth day of September, in the year of our
Lord One thousand eight hundred and twenty-three.
BENJN (L.S.) BAYLIS.
