WHEREAS His present most Excellent Majesty King George the Fourth
did, by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Tenth day of December, One thousand eight hundred
and twenty-eight, in the ninth year of His reign, give and grant unto us,
the said John Boase and Thomas Smith, our exccutors, adñiors, and assigns,
and such others as we, the said John Boase and Thomas Smith, our exors,
adors, 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 mentioned, should
and lawfully might make, use, exercise, and vend, within England, Wales,
and Town of Berwick-upon-Tweed, our Invention of "CERTAIN IMPROVE-
MENTS ON MACHINES OR MACHINERY FOR SCRAPING, SWEEPING, CLEANING, AND
WATERING STREETS, ROADS, AND OTHER WAYS, WHICH MACHINES OR MACHINERY
MAY BE APPLIED TO OTHER PURPOSES;" in which said Letters Patent there is
contained a proviso that we, the said John Boase and Thomas Smith, or
one of us, shall cause a particular description of the nature of our said
Invention, and in what manner the same is to be performed, by an instru-
ment in writing under our hands and seals, or under the hand and seal
of one of us, to be inrolled in His Majesty's High Court of Chancery within
two calendar months next and immediately after the date of the said in
part recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Boase, of Albany Street, Gentleman, one of the partics in the said
Patent named, do hereby, for myself and the said Thomas Smith, Mechanic,
of Augustus Street, both in Regent's Park, in the County of Middlesex, the
other party in the said Patent named, hereby declare that the nature of our
said Invention, and the manner in which the same is to be practised and
carried into effect, is herein-after described (that is to say) :-
It consists of a machine formed by an oblong frame placed on two or more
wheels, which wheels, when put into motion, give a rotatory action to the
brooms by means of a bevelled cog wheel fixed to the main axle, working
another similar wheel on the axle of the brooms, and as the circle of brooms
by this arrangement revolves in an oblique direction to the frame of the
machine, and to the line in which it is to be made to move, the soil and
other substances are gradually removed from the centre of the streets and
roads (where the machine commences its operations) to the sides. A jointed or
flexible scraper is placed in front of the brooms, in nearly a parallel direction
with them, to remove the principal part of the mud and dirt, thereby giving to
the brooms a greater freedom of action. A curved scraper is fixed to the
hinder part of the frame, for collecting the scrapings and sweeping into heaps
ready for removal. A shield on the right side and a covering over the frame
are used for the purpose of confining the sweepings to the space occupied by
the machine, to prevent any annoyance to people passing it while in operation.
The machine commences its work in nearly the middle of strects and roads,
removing the soil and other substances to its right side. After going a con-
venient distance, it returns, displacing another portion in a contrary direction
to that first scraped and swept. This is repeated until the whole of the mud
and dirt is removed to the sides of the streets and roads, where the curved
scraper collects it into heaps. A tank for watering streets and roads may
likewise be placed on some convenient part of the framing, to make it a
complete road machine; but this we do not claim as any part of our said
Invention.
In addition to building and using this machine in its entire state, as above
described, we claim to construct and use machines with the scrapers, exclusive
of the brooms, for cleaning turnpike and other roads where the brooms may
not be required, and also other machines with brooms only for the purpose of
cleaning paved and narrow streets; the machine, either entire or in parts, as
above stated, to be drawn or propelled by manual labour, horse, or any other
power; and although we have set forth the angles of the broom axis and
scraper as we have used the same, yet we claim the right of varying those angles

page_text: and the exact disposition of the parts as exigences or the convenience of the
situation may require. The action and use of the different parts of the
machine are more particularly described, and their form and situation pointed
out, by the following references to the accompanying Drawing:-
Figure 1st is a sectional view of the machine from back to front.

and back part left out to shew the other parts. Figure 3d a plan of the
machine, the water tank and one of the brooms omitted. The same letters
are affixed to corresponding parts on the several Figures. A, A, A, an oblong
frame of wood or iron, to which the supporters of the brooms and scrapers are
attached. B, B, B, two wheels; on the box of each is a groove, which works
on a key in the axle F. One or both of these wheels may when required be
liberated from the axle by sliding them off the key, or in any manner by which
they can revolve without carrying the axle with them. C, C, C, the jointed or
flexible scraper, consisting of a chain of jointed pieces of iron, f, f, to which
the plates, made of metal, wood, or any other suitable substance, are fastened.

,,, two sets of radiating arms fixed on the axle s, s, to carry the brooms or
sweepers. These arms are groved, to admit the ends of the broom stays.
D, D, D, the brooms or sweepers. These consist of a layer of heath or any
other proper substance, confined between the stays u, u, u, by screws. These
stays are secured to the radii 2, 7, by bolts, which project from their ends
through grooves in the radii, and are fastened on the outside by screws and
nuts as at w, w, w, in Figs. 1 and 2. G, G, G, a bevel-toothed wheel fixed on
the axle F, and revolving with it. G, G, G, another bevel-toothed wheel
fixed on the axle s, s. This is worked by the wheel G, G, and carries with it
the whole of the sweeping apparatus. 0, 0, 0, a wooden roller, over and
parallel to the jointed scraper, and turning on pivots at its ends. 9 J chains
or ropes passing round the roller o, o, and connected at their lower ends to the
jointed scraper C, C, by which on turning the roller the scraper will be drawn
up or let down. p, p, p, the lever to raise the jointed scraper. This lever
turns on a fixed joint at one end, at a proper distance from which a chain or
rope is fastened to it, the other end of which is wound round the roller in a
contrary direction to the other ropes or chains q, q, q, by which when the lever
is drawn out, as shewn by the dotted line, Fig. 3, the roller o, o, will be turned,
and the scraper drawn up. The roller is retained by a ratched wheel or a
catch upon the lever p. 1, 1, 1, vertical pieces proceeding from the frame A, A,
to within a few inches of the ground. They are to guide and carry the ends of
the chain f f of the scraper, at the same time allowing it to fly with the

page_text: inequalities of the surface of the road. E, E, a curved scraper attached to the
hinder part of the machine, to be alternately raised and depressed (if by manual
labour) by its handle x, x, to collect the scrapings and sweepings into heaps.
t, t, t, parts which support the axle of the broom wheel. z, a screw to put the
two wheels G and G into or out of gear with each other. 9. g, lever to throw
the wheel B out of gear (when the machine is required to turn), and a similar
lever, though not shewn in the Drawing, may be applied to the other whicel B
also. n, n, steel springs proceeding from the frame A, A, to support the
jointed scraper when it meets with any sudden obstruction. m, m, strengthening
stays to the supporters of the jointed scraper. K, K, only shewn in Fig. 2, a
shield and covering to prevent any dirt from the brooms escaping beyond the
body of the machine. I, I, shafts for horses. These to be taken off, and
replaced by a single pair when no more than one horse is required to draw the
machine, or by a pole with cross bars when drawn by manual labour. Va
spring, which may be of the form shewn in Fig. 1, or be applied in any other
effectual manner, for raising the curved scraper, and keeping it up and out of
action, unless when wanted, and then it may be depressed by the handle x.
In witness whercof, I, the said John Boase, for myself and the said
Thomas Smith, have hereunto set my hand and seal, this Tenth day of
February, in the year of our Lord One thousand eight hundred and
