greeting.
WHEREAS His present Majesty King George the Fourth, in and by His

did give and grant unto me, the said William Ranyard, His special licence,

at all times thereafter during the term of years therein unexpired, should and
lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of a "CIRCUMVOLUTION-BRUSH
AND HANDER;" in which said Letters Patent there is contained a proviso,"
obliging me, the said William Ranyard, by an instrument in writing under my
hand and seal, particularly to describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, and to cause the

page_text: Patent, as in and by the same, reference being thereunto had, will more fully
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Ranyard, do hereby describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, by the Plan or
Drawing hereunto annexed, and the following description thereof, that is to
say:
Figure the 1 shows the circumvolution brush and hander, together with
their connections, uncover'd, except the sliding part, spoken of hereafter, with
the bar marked N; 2d, a brush, of materials as hereafter described, between
two laths wedged thro' iron eyes or rings; 3ª, the receiver or box; 4", the
hander; 5th, the circumvolution wheel in its frame; 6th, the carriage or barrow.
A represents a beam or axle, whereon is fixed, at cach end, a lever or fly with
a rim; B, B, B, B, B, B, shew the openings in the rim to fix the laths thro',
by which the brushes are formed; C, C, C, C, C, C, brushes, as fixed in the
machine, making a circumvolution brush, which also may be formed on a
cylinder, being in various ways attached to it. The materials to form the
brush may be of wood, birch, heath, withey, whalebone, bristles, hair, hop bines,
or anything of an elastic or absorbent nature, and also be enlarged or decreased,
as required. D, the frame, which is placed on the barrow, having an hinge
marked H on each side, by which the brush, when not wanted, by pressing
down a bar to which a wire marked E is latched down, is taken out of gear
and held suspended; E, the wire to latch down, or by being fixed on the bar
before mentioned, keeps the brush in a working state; F, a cog wheel, which
may be enlarged or decreased, to give a slow or quick revolve, as required,
fixed to the beam or axle A; G, principal cog wheel, on the nave of the
barrow wheel; II, the hinge, on which the frame moves when put into or out
of gear; I, the hander or assistant, made of iron, copper, wood, or leather,
for the conveyance of the produce of the brush or brushes into the receiver or
box; J, the box; K, springs, and by which the hander is fixed on the bar 0;
L, a rod or chain, to carry the hander when the brush is out of gear; M,
bandles on the receiver or box; N, a bar, which runs longitudinally on the
frame D, for fixing thereon part of the cover, which slides for the removal of
the receiver or box J; O, the bar, which runs crossways on the barrow or
carriage bearing the hander; P, the carriage or barrow.
Note. It is necessary the whole is covered with wood, cloth, or some other
material, and that it be forced forwards or drawn in that direction which the
brushes work up the hander into the receiver or box.
The utility of my machine is conceived chiefly in taking the light dust off
3

page_text: from roads or streets, which in dry weather is so annoying to passengers or
residents on the public highways, and also may, by application of greater power,
be used to clear away the heavier parts of dirt, &c., &c., and also be found a
prompt way of taking up leaves, grass, &c., &c., from lawns and garden walks,
and may be adjusted to sweeping rooms or passages, and carpets of the most
valuable kind, to great advantage by immediately taking up the dust without
further throwing it over the same, as is done in the customary way of sweeping.
In witness whereof, I, the said William Ranyard, have hereunto set my
hand and seal, the Twenty-eighth day of December, in the year of
our Lord One thousand eight hundred and twenty-five.
