Improvements in and connected with Street Cleaning Machines.
WILLIAM COLIN MORISON 12 The Plain, Mutley, Plymouth, Gentleman do
hereby declare the nature of this invention to be as follows:-
It is a machine consisting of an inclined plain suitably fixed to a rigid frame on
wheels, duly pushed by a horse, and arranged with scrapers, or brushes, so that mud
on the street may be automatically scraped from the street, up the plain and over
upper end into a cart suitably connected with said frame.
its
Said plain is inclined upwards towards the direction in which it is being moved
with its lower end, formed of narrow strips, resting upon the ground which has
been cleaned by fixed scrapers, in advance, which with guiding pieces also direct
the mud towards and to each side of said lower end while other fixed scrapers duly
direct said mud to the rear of said end in such position that other scrapers, worked
by an endless chain, carry said mud up said plain and over it's upper end into a cart
suitably connected with, and in advance of, said frame, to receive the mud; said
frame and cart being moved over the ground together, the frame being pushed by
a horse in rear of it and the cart being pulled by a horse in advance of it,
Said endless chain is duly worked by means of being suitably connected with a
toothed wheel fixed to and concentrically with one of the wheels supporting the
frame. The chain being worked at such speed that the scrapers connected with it
may travel sufficiently quickly to scrape the ground properly.
As soon as the cart is filled it and the machine are stopped so that the said filled
cart may be removed and an empty one put in its place when both the machine and
the cart are started to move again.

Improvements in and connected with Street Cleaning Machines.
WILLIAM COLIN MORISON Lympstone, Devon, Gentleman 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:―
It is a machine consisting of an inclined plain, suitably connected to a rigid
frame on wheels, duly pushed by a horse. The machine is arranged with scrapers,
or brushes if preferred, so that mud may be automatically scraped from the street
up the plain and over it's upper end into a cart suitably connected with said machine.
Fig. 1. is a side view of the machine with part of the frame broken out.
Fig. 2. is a view on top of the machine.
The letters of reference apply to the same parts in both figs.
Said plain a is inclined upwards towards the direction in which the machine is
being moved with it's lower end, formed, preferably, of narrow strips, b, resting
upon the ground, which has been scraped by the fixed scrapers c, d, in front,
which with the guiding pieces close to the side of, and parallel with the centre line
of, the machine (only one of which pieces, e is shewn, in Fig. 1) also direct the
mud towards and to each side of said lower end. At the same time other fixed
scrapers f, g, duly direct said mud to the rear of said lower end and in such position
between the fixed scrapers 7, 8 that other scrapers h (worked by two parallel
endless chains i, j, shown in Fig. 1 by two dotted lines i, i respectively connecting
Price R1

page_text: the upper and lower portions of the wheels, q, r, and in Fig. 2 by two parallel full
lines i, j, connecting said wheels respectively on each side of the machine) carry said
mud up said plain and over it's upper end at a' so that the mud may drop into a
cart which may be suitably connected with, and in advalice of, the machine at A.
The machine and cart are moved together over the ground the former being
preferably pushed by a horse facing the machine and placed between the shafts k, l,
(out of k and and the frame 15 to which they are fixed much is broken) in the
rear of the machine, and the cart being pulled by a horse in advance of it.
The underside of each of the strips 6 is fixed to one end of a'spring b¹ (each
strip being fixed to a separate and similar spring) the other end of which is fixed
to the underside of the plain a so that said spring may duly press the lower end of b
upon the ground at the same time that it duly presses the upper end of 6 on the
inclined surface o, so that the mud and scrapers may pass readily on to and from
the strips 6 on to the plain a; the widths of all the strips bare similar, and equal
to the widths of the scrapers h.
Each of the scrapers c, d, and f, g, is fixed to the outer end of a flat spring the
inner end of which is fixed to the piece m which is fixed to the lower ends
respectively of the frame pieces 9, 10, to which also is fixed the plain a with it's
sides 11, 12, and which pieces respectively also carry the bearings for the shafts np
on which respectively are fixed the wheels y, r.
Said wheels are provided with suitable projections which fit the links of the
chains i, j, so that said chains may be worked simultaneously; a certain number of
said links are provided respectively with a suitable hole on the back, said holes
serving as bearings for the shafts & to work in whilst maintaining said shafts at
suitable distances from, and parallel with, each other.
h
To said shafts are fitted flat springs t to the outer end of each of which is fixed
a narrow scraper (of the width of each of the strips 6) and which narrow scrapers
connected with each shaft are arranged to extend across the plain a and together
are termed h.
In the middle of the shafts respectively and at the backs of the springs tare
fixed pieces carrying the roller u which, when the scrapers are moving up antravel
against the under side of the piece v thus causing said scrapers to press upon a.
When the scrapers in turn have reached the upper end of a the mud is dropped
down at a¹; the scrapers then are carried upwards over the wheel r and are brought
into the position of the upper scraper at B by the roller u first travelling over the
cylindrical piece 1 (fixed to and concentrically with the shaft p) then over and to
the top of the surface x. At this time the roller 2 (working on a pin fixed to the
outer end of the crank 4 the inner ends of which cranks are respectively fixed to
the outer ends of the shafts s) is brought against the surface over the top of which
it is duly carried and down to and over the surface 5, a continuation of the same
surface, 3, but in a different form, duly bringing the scrapers into the position'
shown at c until it reaches the surface 6 by which it is guided into the circular
recess formed concentrically with, but outside each end of, the shaft n where it
remains until the scraper has been placed properly upon the ground as shewn in
the drawing. As his moved inwards (suitably scraping the ground). said roller 2
is duly moved out of said recess and the roller u is brought to bear against the
under side of the surface v which duly presses h on to the plain a:
The scrapers 7 and 8 are suitably connected with the lower ends of the fŕáme
pieces 9 and 10 so that they may be maintained in suitable position for the scrapers'/
to pass between them and by means of suitable springs they are caused to bear
'properly on the ground.
The frame pieces 9 and 10 are firmly fixed together and are supported by and
are free to work, as required on the pin 13 fixed to a piece projecting above
the piece 14 which is fixed to the frame 15 to which is fixed the shaft 16 on which
the wheels 17 and 18 revolve.
Thus when desired the fixed scrapers d, e, f, g, and 7, 8, may readily be raised
off the ground by moving upwards the lower ends of the frame 9, 10, which may

page_text: readily be done by means of a rack connecting with 9, 10, and gearing with a
toothed wheel suitably connected with the frame 15; when desired instead of
using the pin 13, the shaft 16 may be arranged to suitably support said frame pieces.
The piece is maintained in suitable position by being rigidly connected, by
means of the pieces 24, 25, with the frame pieces 9, 10.
The scrapers c, d, f, g, are placed respectively as shown, instead of each set
being in line, so that they may work the better.
I do not confine myself to the gearing as described and shown for working the
chains i, j, and the scrapers h.
To, and concentrically with, the wheel 18 is fixed the bevelled toothed wheel 19
which gears with the toothed wheel 20 fixed to the shaft 21 to the upper end
of which is fixed the bevel toothed wheel 22 which gears with the toothed wheel 23
which is fixed to the shaft p, and in that manner enabling the wheel 18, when
revolving, to cause the wheels r, r, to work the chains i, j, and, of course, also the
scrapers h.
If preferred, each set of the scrapers d, c, f, g, and 7, 8, may be arranged to be
placed upon, and raised from, the ground separately.
In lieu of a horse, or horses, being placed in the rear of, and caused to push, the
machine the required horse power may be arranged to pull the same, by being placed
either by the side, or in front, of the machine.
When desired any or all of the fixed scrapers, or any or all of the scrapers h,
may be replaced by brushes (instead of scrapers) so that their action may be that
of brushing instead of scraping.
The machine is chiefly intended for raising mud or dust from roads or streets,
and it may be made of a small size to be worked by hand on floors or railway
station platforms &c.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The construction or general arrangement and combination substantially of the
invention, substantially as hereinbefore described, and shown in the accompanying
drawings.
