An Improved Street Cleaning Machine.
I, PIERRE HAERST, Manufacturer, of 161, La Salle Street, Chicago, Illinois,
U.S.A., 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:-
1
This invention is a street cleaning machine, designed to clean the roadway and
deposit the matter taken therefrom in a removable receptacle carried on the
frame of the machine.
The machine embodies a frame, the principal weight whereof is supported by
wheels; a removable receptacle on the frame, an apron frame, an apron, a shovel
at the forward edge of the apron, brushes passing over the apron and removing
articles on the apron to the receptacle, and means for adjusting the several parts
relative to each other.
In the drawings accompanying and forming a part of this specification, and
wherein a letter of reference applied to designate a given part is used to indicate
such part throughout the several figures, wherever it appears; Fig. 1 is an end
elevation of a street-cleaning machine embodying this invention; Fig. 2, a
vertical, sectional view, adjacent to the driving-wheel of the machine, showing
the apron and shovel and an adjustable shoe, (which may be used), in proper
relative position; Fig. 3, an end elevation of the small gear wheel, mounted
loosely on the main driving shaft of the machine, and of a pin in such driving-
shaft, whereby the rotation of the gear may be made to rotate the driving-shaft,
when desired; Fig. 4, a side elevation of the gear wheel and shaft, forming a
clutch, illustrated in Fig. 3; Fig. 5, a side elevation of the upper end of the apron
frame and of the main frame of the machine, to which the apron frame and the
axles of the machine are secured; Fig. 6, an end elevation of the lower end of
the apron frame and the parts attached thereto; Fig. 7. a perspective view of a
shoe, adjustably and removably attached to the lower end of the apron frame for
use on soft roads; Fig. 8, a perspective view of a portion of the brush chain and
the brush holder of the machine; Fig. 9, an end elevation of a dirt-receptacle,
removably attached to the machine. Fig. 10 is a longitudinal section of a sand
box mounted on the frame.

receptacle is mounted on the machine. The forward part of receptacle h rests
on horizontal member e of frame d, and is maintained in position by gravity,
the forward part of the receptacle being supported by the horizontal member e,

movement of such wheel r, which is controlled by handle 24,
engaging with groove 26 on the hub of wheel w. Handle 24 is fulcrumed at 27
to the vertical member of frame d. The bearing of shaft may be, simply, a
recess (2). at the upper end of vertical member c, on each side of the frame d.
3.3. are sprocket chain wheels, rigidly secured, respectively, to shaft r. on each
side of the machine to rotate therewith. 4 is a sprocket chain wheel, rigidly
secured on shaft 5 to rotate therewith, such shaft being rotatably mounted in
apron frame m, near the lower end thereof, (see Figs. 1, 2 and 6). 6, 6, are
brush chains, extending. respectively, over sprocket wheels 3. 4. and 3, 4, 7, 7.
are brush sockets secured at intervals on brush chains 6, 6, and 8, 8 are brushes
in sockets 7. Brush sockets 7, 7, comprise, respectively a bed (16), sides 9, 9,
and turned-in edges 10, 10, and the brushes 8, 8, are respectively, slidden thereinto.
11 (Fig. 2), is a roller mounted on shaft 12, in adjustable frame 13, arranged to
be forced against chains 6, 6. to adjust them and the brushes thereon, relative to
the lower end of apron o. 14, is a bolt extending through slot 15, of frame 13,
and through apron frame m.
17 is a shovel, adjustably secured at the lower end of the apron frame to such
apron frame by bolts 18, 18 passing through slots 19, 19, respectively. 20 is a
loop or pocket on the under side of shovel 17, and 21 is a shoe, the forward end
whereof, extends into such loop or pocket. 22 is a bolt extending through slot 23
in shoe 21, and through apron frame m, by means of which shoe 21 is adjustably
secured in place. The shoe 21 is removable, being intended for use on other than
concrete pavement. For the purpose of sanding smooth streets after cleaning.
I mount a box 28 on standards 29 on the top of the frame over the brushes and
having perforations in the bottom, a plate 30 having corresponding perforations
is placed slidingly underneath the box to permit the perforations to come in
line with the perforations in the box, or to cover the perforations wholly or in
part as may be required to regulate the flow of sand. This plate 30 is moved by
means of a connecting lever 36 placed at the side of the box. An apron 31 is
placed underneath the box upon which the sand falls and is deflected rearward
of the dirt receptacle ; a shaft 32 passes longitudinally through the box adjacent
the bottom, having bearings in the ends of the box, this shaft is partially flattened
to permit a flange 33 to be attached longitudinally which is intended to prevent
the sand clogging the perforations. This rod projects at one end of the box and
carries on the projecting end a sprocket wheel 34 which is connected by a sprocket
chain 35 with another sprocket wheel on the hub of the wheel which carries the
machine.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
In a street cleaning machine, a U-shaped frame mounted on wheels

secured in said apron frame, a driving wheel secured to one of the wheels of the
mounted frame, a wheel engaging with the driving wheel on one of the rotatable
shafts, a clutch to said wheel, chain wheels on the shafts, chains over the chain
wheels, brushes removably attached to the chains, roller frames adjustably attached
to the apron frames adjacent the lower end of the apron, rollers rotatably mounted
in said roller frame adapted to engage with the chains, shoes removably attached
to the apron frame adjacent the shovel, a sand distributing box mounted over the
brushes and having a perforated bottom, a sliding plate underneath said box
having corresponding perforations, means for sliding said plate, a rearward
extending apron attached to the bottom of said box, a shaft longitudinally through
said box provided longitudinally with a flange, a sprocket-wheel on the end of
said shaft connected by a chain with a wheel on the hub of the wheel of the
