A NEW COMBINATION OF MACHINERY OR NEW MOTION FOR SUPERSEDING THE NECESSITY OF THE ORDINARY CRANK IN STEAM ENGINES, AND FOR OTHER PURPOSES WHERE POWER IS REQUIRED
Year: 1827

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
BARLOW, of Jubilee Place, Chelsea, in the County of Middlesex, Gentleman,
send greeting.
WHEREAS His present Majesty King George the Fourth, in and by His
Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the First day of February
last, for Himself, His heirs and successors, did give and grant unto me, the
said Robert Barlow, my executors, administrators, and assigns, His special
licence, full power, sole privilege and authority, that I, the said Robert
Barlow, my executors, administrators, and assigns, and every of them, by
myself and themselves, or by my and their deputy or deputies, servants or
agents, or such others as I, the said Robert Barlow, my executors, admini-
strators, or assigns, should at any time agree with, and no others, from time to
time and at all times thereafter 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, my Invention of "A NEW COMBINATION OF
MACHINERY OR NEW MOTION FOR SUPERSEDING THE NECESSITY OF THE ORDINARY
CRANK IN STEAM ENGINES, AND FOR OTHER PURPOSES WHERE POWER IS REQUIRED;"
in which said Letters Patent there is contained a proviso obliging me, the said
Robert Barlow, by an instrument in writing under my hand and seal, par-
ticulary to describe and ascertain the nature of my said Invention, and in
what manner the same is to be performed, and to cause the same to be in_

page_text: rolled in His Majesty's High Court of Chancery within six calendar months
next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereto had, will more fully
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Robert Barlow, do hereby describe and ascertain the naturo of my said Inven-
tion, and in what manner the same is to be performed, by the plan or Drawing
in the margin of these presents, which plan or Drawing is delineated upon a
scale of two inches to a foot, and the following description thereof, that is
to say:-
I combine three wheels with an impetus wheel, which, from its peculiar
form and make, I call a beetle impetus, and which may be made hollow,
and the beetles and arms so loaded with quicksilver as to create an immense
power, see Noto * (two or more of which may be added if necessary), two
levers or slings, a union head or cap, a pulley, a steelyard, and a shifting
weight, the magnitude of the wheels, lovers, or slings, union head or cap,
pulley, steelyard and weight respectively, being proportionably adjusted to the
stroke and power of the particular engine as desired, see Note †, when the
motion is attached to a steam engine, and to the particular force songht to be
obtained when the motion is adopted for other purposes requiring power.
Figure 1 is the front view of the motion as attached to a single steam engine
complete for action, with the cylinder inverted, the piston standing at the half
stroke; a, is the axis or shaft where the machinery to be put in action is to he
attached. b, b, is the impetus wheel, and the end of one of the beetles. c is
the pinion or small wheel. e, e, are the levers or slings which are attached by
screws and nuts (as at Number 2, 2,) to the large wheels d, d, and to the cup
or union head f, to which is screwed a socket i, with pin to confine the toe of
the piston rod, as at Number 1. 9 is a steelyard, on which is a slide and
weight w, to adjust and reduce the repulsive power of the friction, take off the
labour, and give ease to the action of the piston. One end of the steelyard is
sustained by a screw at 7, and from the other end of it (m) is conducted a cord,
gut, or chain over the pulley or wheel h, to the centre of the union head or cap f,
to which the cord, gut, or chain is attached; the steam entering into the cylinder
underneath the piston raises it, and the rod then drives the cap or union head
upwards rectilinearly and puts the whole motion into action; when the piston
reaches the top of the cylinder, the steam being introduced above depresses it,
and the piston rod drives the cap or union head downwards rectilinearly, there-
by continuing the action of the machinery during the rise and fall of the
piston. The weight on the steelyard operates to diminish the vibration and

page_text: friction, and to equalize the motion. Number 1, 1, represents the piston rod
and cap or union head. Number 2, 2, represents the front and side section of
the levers or slings. Number 3, 3, represents the side section of the pin and
bracket, to which one end of the cord, gut, or chain is attached at the cap or
union head. Number 4 is the front and side section of the pulley, with screw
and nut. Number 5 is the front and side section of the plate, pin, and screw,
as attached to the cap or union head f. Number 6, 6, 6, is the front of the
steelyard, slide, and weight, and the top of the same with holes for the pointed
screw of the slide 6, to enter and make stedfast the weight to any part of the
steelyard, as required. Number 7 is the cylinder inverted and placed in such
a position that the full power of the motion may act upon it, but the framing
and fixing it for the motion may be done in various ways and forms according
to the judgment and taste of the engineer. Figure 2 is the side view or sec-
tion of the motion for a single engine, as in Figure 1. Figures 3 and 2
represent the side view or sections of a double engine, shewing in what manner
they may be united, and a double power obtained nearly in the same space, and
worked by one shaft and by one stroke. Figure 4 and 5 is the small wheel,
à pinion as at a in Figure 1, and the side section as on the shaft of the engine.
Figure 6 represents the side section of the motion inverted, as attached for a
hand power to a force or common pump. a, a, are the winches for two or
more men to work. b, b, b, the beetles of the impetus wheel enlarged in
scale, which for a hand motion must always exceed the circle of the winch, and
the further the extent beyond the greater the power. c, c, are the cap or union
head, with section, which encloses the ends of the levers or slings, which differ
in a small degree from the cap or union head f in Figure 1, by being made
double, but I believe where sufficient strength is given it is not very material.
d, d, is part of the frame, and inclosed in any form requisite. e, e, are the
bearings of the shaft as fixed in the internal part of the frame by screws. fis
the end of the bar which goes across, forming the support and bearing of the
two large wheels, levers, &c., as d, d, in Figure 1. The pump, with condensor,
bearings, well, &c. I do not describe, as not belonging to my Patent, and is
only laid down to shew how my Patent motion can be attached thereto, as a
specimen of its application.
a
In witness whereof, I have hereunto set my hand and seal, this Thirty-
first day of July, in the year of our Lord One thousand eight hundred
and twenty-seven.
Note. A common plain wheel, with a sharp verge outside, and inside of a
proportionable diameter and weight, or a like wheel, made hollow with a

page_text: number of regular divisions, and each division loaded with an equal quantity,
of quicksilver, may be used in the same position with good effect.
Note t. This combination of machinery may be advantageously multiplied
where a greater power is required. In Figure 2 and 3 it is doubled.

AND BE IT REMEMBERED, that on the same Thirty-first day of July,
in tho year above mentioned, the aforesaid Robert Barlow camo before our
Lord the King in His Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained, in form above written. And
also the Specification aforesaid was stamped according to the tenor of the
Statute in that case made and provided.
