page_text: I, WILLIAM SMITH of Barnard-Castle in the County of Durham, Machine Maker,
do hereby declare the nature of this invention to be as follows:-
My invention relates to machines used for scraping and removing dirt dust or
snow from Streets or Roads and more especially to that form of machine for which
I obtained Her Majestys Royal letters Patent dated 30th May 1865 & numbered
1477.
My present invention has for its objects further improvements in the construction
and arrangement of the parts of the machine described in the said specification of
the said letters Patent, by which the machine is more easily worked, adjusted guided
& regulated, whilst the scraping appliances are simple, effective and durable.
In the accompanying drawing which is an illustration of my invention. Fig. 1
is a plan of scraping machine. Fig. 2. side elevation of the same. Figs. 3 and 4.
showing the novel form of a scraper tooth and spring.
A, A, is the frame of the machine; B, B, the axles; C, C, the travelling wheels;
D, D, the scrapers which remove the dirt or snow from the road.
E, E; The springs. F, F, the top bar to give pressure to the springs E.-
G, G, The under or notched bar to guide and keep the springs in a proper position.
H, is a lever which raises the scraper teeth D, from the ground when necessary.
I, is a movable bar attached to the lever H, by means of which the lever is enabled
to raise the scrapers D.
J, J, is the pole by means of which the machine is drawn along the road.
K, K, are two front wheels, L, L, the axle of front wheel, K.-M, M, is an
upright shaft attached to the front axle L.
There is a bolt which passes through the lower end of the upright shaft M,
which is guided in a square socket and acts as a pivot to enable the wheels K, K, to
fall to the inequalities of the road in travelling along.-N, is the top guide to
the upright shaft M, the side bars 0, 0, are supports to the upright shaft M.
When the scrapers are not required to work the lever H, is placed under the
notch on guide bar P, P, the same guide bar P, has four or more notches at the top,
upon which the lever H, rests and gives the desired pressure to the scrapers D, D,
according to the state of the road.-R, R, is a connecting rod placed behind the

page_text: scrapers D, and which passes through the three eyes of the scrapers D, to bind them
together and at the same time allow them to rise and fall to the unevenness of the
road;S, S, are screw supports to the top bar F, F, which enables the top bar to be
set and regulated in a proper position.
T, T, are stays which strengthen the frame A.
U, is a seat for the driver of the machine carried by the supports or stays V.
X, X, is a plate fixed to the scrapers D, for giving greater depth to the scrapers
for removing snow.
Having now described my invention and the manner in which it is to be performed,
I claim-
First. The scraper teeth made of hard or chilled metal or steel, which makes them
more durable for the purpose substantially as described and shown.
Second. The method of giving greater depth to the teeth for the purpose of
removing snow by fixing a plate of iron or wood the full depth of the scraper teeth
and connections, substantially as described and shown.
Third. The top or notched bar for regulating and giving pressure to the springs,
substantially as described and shown.
Fourth. The screw supports to the top bar for adjusting the desired pressure upon
the springs substantially as described and shown.
Fifth. The fork or lifting apparatus which works upon the same centre as the
teeth by which means the scrapers are more easily raised from the ground substan-
tially as described and shown.
Sixth The method of connecting the front wheel or wheels to the frame which
enables the machine to keep always level with the road, substantially as described and
shown.
Seventh. The square socket with pivot attached to the upright shaft of front wheel
or wheels by which the wheels will fall to the unevenness of the road substantially as
described & shown.
In witness whercof, I, the said William Smith, have hereunto set my hand and
seal, this 1st day of November in the year of our Lord One thousand eight
hundred and eighty six.

page_text: I WILLIAM SMITH Engineer and Ironfounder Barnard-Castle County of Durham
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to machines used for Scraping and removing dirt, dust, &
Snow from Streets or roads and more especially to that form of such machine for
which I obtained Her Majesty's Royal letters patent dated 30th May 1865 No. 1477.
My present invention has for its objects further improvements in the construction
and arrangement of the parts of the machine described in the said specification of the
said letters patent by which the machine is more easily worked adjusted, guided and
regulated, whilst the scraper appliances are simple effective and durable.
In the drawings left with the provisional specification, which is an illustration of
my invention Fig. 1 is a plan of the machine. Fig. 2. side elevation of the same.
Fig. 3. & 4. showing the novel form of one of the Scraper teeth and spring. A. A.
is the frame of the machine.-B. B. the axles.-C. C. the travelling wheels.-D. D.
the scrapers which remove the dirt or snow from the road are made of hard or chilled
metal or steel which makes them more durable.-E. E. the springs.-F. F. the top
bar to give pressure to the springs E.-G. G. the under or notched bar to guide and
keep the springs in a proper position.-H is a lever which raises the scrapers D from
the ground when necessary.-I is a moveable bar, attached to the lever H, by means
of which, the lever is enabled to raise the scrapers D.-J. J. is the pole, by means of
which, the machine is drawn along the road.-K. K. are two front wheels.-L. L. the
axle of front wheels.-M. M. is an upright shaft attached to the front axle L.-There
is a bolt or pin, which passes through the lower end of upright shaft M which is
guided in a square socket, and acts as a pivot, to enable the wheels K. K. to fall to
the road in travelling along.-N. is the top guide to the upright shaft M.--The side
bars O. O. are supports to the upright shaft M.-When the scrapers are not required
to work the lever H is placed under the notch of guide bar P. P., the same guide
bar P. has four or more notches at the top, upon which the lever H rests and gives
the desired pressure to the scrapers D. D. according to the state of the road.-R. R. is
a connecting rod, placed behind the scrapers D, and which passes through the three
eyes of the scrapers D. to bind them together and at the same time allow them to rise
or fall to the unevenness of the road.-S. S. are screw supports to the top bar F. F.,
which enable the top bar to be set and regulated in a proper position.-T. T. are stays
which strengthen the frame A.-U. is a seat for the driver of the machine carried by
the supports or stays V.-X. X. is a plate for giving greater depth to the machine
for removing snow and is fixed to the scrapers D. I also fix a squeegee made of
india-rubber to the scraper teeth D. for removing slops from wood or asphalt
pavements.

page_text: Having now described my invention and the manner in which it is to be
performed I claim-
1. The scraper teeth made of hard or chilled metal or steel, which makes them
more durable for the purpose described and shewn.
2. The method of giving greater depth to the teeth for the purpose of removing
snow by fixing a plate of iron, steel, or wood, the full depth of the scraper teeth and
connections as described and shewn.
3. The top or notched bar for regulating and giving pressure to the springs.
4. The fork or lifting apparatus which works from the same centre as the teeth by
which means the scrapers are more easily raised from the ground.
5. The screw supports to the top bar for adjusting the desired pressure upon the
springs, substantially as described and shewn.
6. The method of connecting the front wheel or wheels to the frame and which
enables the machine to keep always level with the road substantially as described and
shewn.
7. The square socket with pivot attached to the upright shaft of front wheel or
wheels, by which the said wheels will fall to the unevenness of the road, substantially
as, and for the purpose described and shewn.
8. The application to a road scraping machine of an Indiarubber squee-geo for the
purpose of removing slop from roadways.
