I, CHARLES Hvass, of No. 119 East 113th Street, in the City of New York,
in the County and State of New York, United States of America, Machinist, 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.—
The invention relates to improvements in street sweeping machines, and cousists
in the novel features and combinations of parts hereafter described.
The machine constructed in accordance with my invention embodies a novel
supporting frame mounted on wheels and provided with a revoluble brush, a
detachable receptacle to receive the sweepings, a reversible pivoted handle which
may be used at either end of the machine, clutch mechanism to prevent the blush
from revolving except in one direction, and means for raising and lowering the
brush, together with auxiliary parts for giving effect to the main features above
referred to The said machine also embodies means located on the frame for
supporting a shovel and a hand brush on brushes, with which the machine is
equipped
The machine involves in its use a now method of cleaning streets and removing
the sweepings, the object being to dispense with many expenses and annoyances
incident to the present manner of cleaning streets.
In accordance with my
Invention each machine will carry a removable receptacle to receive the dut swept
up by the revoluble brush, which receptacle when filled will be detached and left
on the street to be taken up with other similar filled receptacles removed from
other sweepers, by a cart or wagon which will carry the receptacles thus gathered
up to the dumping ground, where they will be emptied. As soon as the receptacle
on the sweeper has been filled, it will as above stated be removed, and thereupon
another receptacle will be applied to the sweeper and the operation of the latter
continued until this second receptacle has become filled, whereupon it will be
emoved and a further receptacle attached to the sweeper to receive the sweepings
arising from the continued use of the machine. The body of each sweeping
machine is specially adapted to receive the receptacles in a convenient manner, and
each body will be provided with means for holding a shovel and hand broom or
brush, which may also be readily removed for use in gathering the dirt and
depositing it in the receptacles.
The invention will be fully understood from the detailed description hereinafter
presented, reference being had to the accompanying drawings, in which,
Figure 1 is a top view of a street sweeping machine constructed in accordance
with and embodying my invention;
Figure 2 is a side elevation of same,
Figure 3 is an enlarged detached top view of a portion of the machine, showing
the gearing for revolving the bush,
Figure 4 18 a detached longitudinal section of a clutch which is located
intermediate the main supporting wheels and axle therefor, and
Figure 5 is a detached face view of same.
In the diawings A designates the main body or fiame of the machine, B the
evoluble brush, C the detachable receptacle to receive the sweepings, and D the
reversible pivoted handle.
The fame A of the machine consists of the metal bent bar E forming the
opposite sides, front and rear of the supporting body, the sides being parallel with

page_text: each other and connected by the transverse bars F, G
The bar E at the front
end of the main frame constitutes a bar, lettered H, to which is detachably secured
the receptacle C At the rear of the machine the bar E outlining the frame
thereof forms a tapering section 1, to which is seemed the casting J, whose outer
extremity constitutes the sleeve K to receive the stem of the swivel L carrying
the wheel M The swivel L and wheel M are of usual construction, but between
the casting J and the lower part of the swivel stem is secured the spring N, whose
free end receives the stram exerted by the weight of the end of the machine and
dung the use of the machine the said spring N receives any shock which may
arise owing to the wheel M passing over rough surfaces. The casting J projects
outward sufhciently to enable the wheel M to have a revolving m tion around the
vertical axis of the swivel-stem without interfering with the bush B, and sand
casting strengthened by theais 0, 0 extending from the lower portion of the
sleeve K thereot to the main frame of the machine The fiame A is constructed
with a view of obtaining great strength with lightness in weight, and also to have
the same open in order that the attendant may see and examine all of the operative
parts of the machme
The revoluble bush Bis mounted at an angle to the transverse center of the
machine and is retained at its ends by the aims P, Q, the former of which extends
from the lug R secured to one side of the machine, while the aim is journalled
on the short shaft S having the sprocket wheel T and pinion wheel V, the latter
being in engagement with the bevel gear wheel W secured upon the axle X for the
wheels Y, Y, upon which the machine travels The shaft of the brush B 18.
jounalled in the ends of the arms P, Q. aud said shaft at one end of the brush is
provided with the sprocket wheel a which is connected with the sprocket wheel T
by means of the chain b
The sprocket wheel T and pinion wheel V are connected
together or made in one piece and revolve upon the shaft. S, which is stationary.
The evolving motion of the brush B is imparted to it from the axle X through the
beveled gear wheel W, pinion V, sprocket wheel T, chain and sprocket wheel a,
the bush continuing to evolve dining the forward traveling movement of the
machine and cea-ing upon the stoppage of said machine.
In order that the binsh B may not revolve during any backward movement of
the machine on the wheels Y there is provided in the hubs of the said wheels clutch
mechanism, which during the forward travel of the machine will lock the axle X
and the wheels Y together so that the motion of the wheels Y will be communicated
to the axle X, and by it communicated through the gear wheels W, V and
sprocket wheels T, a, to the brush B, but when for any reason the machine shall
be given a backward motion the clutch mechanism will be disengaged and at such
time the wheels and axle X will not be locked together and hence the wheels Y
will travel freely upon the ends of the said axle X without revolving the same, the
result being that the gear wheels W, V, will not be rotated and the brush B will
remain at est I do not limit the invention to any special form of clutch
mechanism intermediate the ends of the axle X and the wheels Y, but recommend
the clutch llustrated in Figures 4 and 5 the said clutch consisting of the toothed
wheele keyed upon the axle X and enclosed within the casing d fitted to the hub
of the wheels Y, the said casing having a sleeve d¹ which enters the said hub.
Intermediate the teeth of the wheel e and the interior surface of the casing d are
the series of rollers. During the forward travel of the machine on the wheels Y
the rollers traveling down the inclines of the teeth of the wheel e will be bound
against the interior surface of the casing d and thus lock the said casing and
wheel e together, whereby the wheels Y and axle X will be connected and the
motion of the former will be communicated to the latter in a well known manner.
During the reverse movement of the wheels Y, the rollers will remun free in the
large part of the recesses retaining them and hence will not operate to pin the
casing d and wheel e together, and at such time the wheels Y will turn freely upon
the ends of the axle X, but will not rotate the latter.
The bush B may be raised or lowered at will by means of the pivoted lever g

having a handle h at one end and at the other end connected by the suspended
bifurcated arm with the cross Uai extending between and secured to the
swinging arms P, Q, which connect the bush with the machine. The lever is
pivotally mounted in the standard m and has at one end the locking wheel n,
screw o and clamping plate p. The screw o passes though the slot of the vertical
guide and carries the said plate p at one end and the wheel at the other end,
the purpose being to enable the locking of the lever g at any desued position along
the gunde q by means of the screw o Upon loosening the wheel n the lever y may
'be raised or lowered at will, and then secured in any set position by tightening the
wheel n.
When the 'machine is in use the handle of the lever g will be raised
and the brush B thus lowered to the ground, and when the machine is not in use or
is in comise of transportation, the haudle of the lever q will be depressed and the
other end thereof thus caused to elevate the bar 1. arms P, Q, and brush B
Upon the frame A is secured the tool box r, which is provided at opposite ends
with hooks s adapted to pass upon the transverse bais II, F, as illustrated
Figure 1, and thus retain the said box in place.
At the front of the fiame A is secured the receptacle C for the sweepings, the
latter after having been left by the brush B being thrown into said receptacle by
'means of an ordinary shovel. The receptacle C is a transversely elongated metal
box extending the full width of the fame A and detachably seemed to the
transverse bai II thereof by means of hooks t, which are firmly secured to the
upper edges of the said receptacle and are of sufficient size to pass downward over
the said bar H, as in Figme 1 The receptacle C is provided at each end adjacent
to its upper edges with the handle to and at its lower rear side with the handler,
the said handles being necessary for use in detaching the receptacle from the
sweeping machine and for convenience in dumping the same. At the center of the
upper edges of the receptacle C is provided the connecting brace y, illustrated by
dotted lines in Figure 1, and to which when the receptacle is in place on the
inachine is attached the lower hooked end of the toda, the upper end of which is
secured in an eye at the upper end of the standard E. The purpose of the
brace y is to strengthen the receptacle and afford a means by which with the use of
the rod the receptacle may be sustained in a vertical position and not be
permitted to swing inward at its lower end. The receptacle C is of substantial
capacity and its lower edge is adjacem to the surfaces over which the wheels Y
travel, and hence the said receptacle will be capable of receiving a large quantity
of the sweepings resulting from the action of the bush B and may be lifted to the
ground without undue exertion on the part of the attendants, it being simply
necessary for them to unhook the iod z from the brace y and by means of the
handles w to elevate the said receptacle sufficiently for the hooks t to be relieved
from the transverse bar II, at which time the said receptacle may be lowered to the
ground
It will be observed upon reference to Figure 1 that the axle X is adjacent to
the front of the frame A and that the receptacle C is suspended from said frame at
a point adjacent to said axle so that its ends are substantially between the
wheels Y, Y, while the brush B and swivel L. are at a point sufficiently in rent of
the axle X to properly balance the weight of the machine at opposite sides of the
said axle. When the receptacle C is full of sweeping its weight will not have any
tendency to elevate the rear of the machine but on the contiary the parts of the
machine being then about evenly distributed at opposite sides of the said axle the
machine will continue to iuu' freely.
At about the center of the hame A is provided the standard 3, in the upper end
of which is pivoted the handle D, which is of sufficient length to be used at either
the front or the rear end of the machine At opposite sides of the standard B' are
secured the standards D', E', the said standards consisting of inclined diverging
braces G forming at then upper ends the pockets II' of a size adapted to receive
the handle D and permit of the latter being locked therem by a pin.
When it is
desired that the attendant shall move the machine while at the front thereof,

page_text: the handle D will be tuned frontward and locked in the pocket H' at the upper
end of the standard E', as illustrated, at which time the attendant may grasp the
cross-bar on the end of the handle and move tho machine at will, while, it it is
desned that the attendant shall operate the machine from the rear thereof the said
handle D will be tuned toward the rear and locked in the pocket II', at the upper
end of the standard D', in which condition the handle may be grasped by the
attendant standing at the rear of the machine The standards D, E, are durable
and not likely to become bent or bioken in nse
In the front of the brush B there is suspended by means of hooks and eyes I',
the fender board J', which extends downward in near relation to the ground and
the purpose of which is to prevent the dirt being scattered by the brush B.
Upon the upper surface of the frame A are provided the pockets K', L', for the
shovel M and brush N respectively, said shovel and brush being supported on the
frame of the machine and being held at their handles in the said pockets K', L'.
At one side of the frame A is secured the metal pocket to receive the handle of
the brush P, as illustrated more clearly in Figure 2. The machine will be
equipped with the shovel M', brush N¹ and brush P¹, and said articles will come
into use during the operation of the machine in cleaning streets.
In the use of the machine, the bush B will be lowered and the machine set in
motion, the result being that the street will be swept by means of the brush and
the dut duected to one side of the wheel Y, owing to the fact that the brush is at
an angle and its edge extends outward beyond the edge of said wheel Y. The
dirt swept up by the bush B will be shoveled into the receptacle C until the
latter has become filled, whereupon the machine will be stopped and the receptacle C
removed and placed aside and an empty similar receptacle applied to the bar II,
after which the cleaning of the street will be continued until this second
receptacle has become filled, whereupon the machine will be again stopped and
the receptacle removed as before The filled receptacles C diopped along the
route of the cleaning, will be gathered up by a wagon or cart and taken to the
dumping ground where they will be emptied.
