Year: 1866

page_text: Sealed the 22nd September 1866, and dated the 6th August 1866.
COMPLETE SPECIFICATION filed by the said William Smith at the
Office of the Commissioners of Patents, with his Petition and Decla-
ration, on the 6th August 1866, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, WILLIAM
SMITH, of Barnard Castle, in the County of Durham, Machinist, send
greeting.
WHEREAS am in possession of an Invention for "AN IMPROVED HORSE-
ROAD SCRAPER AND BRUSH," and have petitioned Her Majesty to grant unto
me, my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn declaration that I am the first and
true Inventor thereof.
NOW KNOW YE, that I, the said William Smith, do hereby declare
that the following Complete Specification under my hand and seal fully

page_text: descrives and ascertams the nature of the said invention, and in what manner
the same is to be performed, in and by the following statement:-
Fig. 1 represents a plan of the machine.
Fig. 2 represents a side elevation of the machine.
Fig. 3 represents an enlarged view of the scraper and its spring.
The nature of my Invention consists, first, in the manner of placing the
scrapers in front of the brush, being placed at an angle to the direction in
which the machine moves along the road, enabling them by that means to
deliver the mud on one side as the machine moves along.
Secondly, the manner of fixing the brush; being also fixed at an angle to
the direction in which the machine moves along the road, allowing it by that
means to be drawn directly along the road, and clearing itself of mud or dust
on the way.
In the above-mentioned Drawings A, A, A, A, represents the hauling
frame attached to the axles (C, C,) of the machine by means of the iron bars
R, R, R,. B, B, B, B, are the supporting wheels, and C, C, their axles.
D, D, D, is the frame containing the scrapers E, E, &c. The frame D, D, is
supported by the axles C, C, to which it is rivetted at L, L. The frame D, D,
is further strengthened by iron stays F, F, attaching it to the axles C, C, and
to the hauling frame A, A. E, E, E, (see enlarged view in Fig. 3) are the
scrapers fixed in the frame D, D, by means of the bar J, J, upon which they
move freely so as to fall upon the road by means of their own weight. If the
weight requires to be increased, that is effected by means of the springs
K, K, K, (see Fig. 3 for enlarged view) which are pressed down by means
of the horizontal bar G, G, causing the scrapers to press with additional weight
upon the road, yet permitting them still to rise and fall over stones and
inequalities. The scrapers are raised from the ground when required by
means of the horizontal bar H, 11. The horizontal bars H, II, and G, G,
are attached to each other at 1, 1, and both of them raised and lowered
by means of the levers P, P, and M. The lever M moves upon the
fulcrum S, and when pressed down forces down the bar M, causing the
levers P, P, which move upon the fulcrum Q, to raise the bars H, H,
and G, G, the bar H raising the scrapers along with it. When required
to leave the scrapers raised the lever M is fixed in the notch at the
bottom of the upright bar N. When pressure is required upon the scrapers
the lever M is raised, thus raising the bar m, causing the levers P, P,
working on the fulcrum Q to draw down the bars H, H, and G, G, causing
giving additional weight
the bar G, G, to press upon the springs K, K,
to the scrapers E, E. When the pressure is required to be constant the lever M.

page_text: may be placed in one of the notches on the top of the bar N. T, T, are circular
brushes which are made to revolve behind the scrapers E, E, so as to remove
any mud or dust the scrapers may have left. 0, 0, is a chain attached to the
supporting wheel B and the pulley Z causing the two puileys Z, Z, to revolve
in opposite directions by means of the crossed endless chain Y, and so carrying
the brushes T, T, round in such a direction as to sweep the mud or dust
before them. U, U, are stays to support the brushes T, T, in their position;
they move freely upon the pivots, W, W, so as to allow the brushes to press
upon the road by their own weight. V is a chain attached to the hauling
frame A, A, and the upright bar X, by shortening which the brushes may be
raised from the ground when necessary.
Having thus fully described the nature and object of this invention, what I
claim is,―
1st, the scrapers E, E, placed in front of the brushes T, T, at an angle
with the direction in which the machine moves along the road, allowing
the mud by that means to slide off in the direction a, and taking away
the greater part of the mud, so as to enable the brushes to clean the road
more effectually.
2nd, I also claim the brushes T; T, placed at an angle with the direction
in which the machine moves along the road, enabling them to deliver the mud
or dust in the direction as the machine moves along.
3rd, I also claim the shape of the springs K, K, and the method of fastening
them to the socket (see Fig. 3) of the scrapers, which springs are used for
the purpose of causing the scrapers E, E, to press with greater weight upon
the road when the mud is stiff and requires more pressure upon the scrapers
to remove it effectually.
In witness whereof, I, the said William Smith, have hereunto set my
hand and seal, this Third day of August, in the year of our Lord One
thousand eight hundred and sixty-six.
WILLIAM SMITH. (L.S.)
