An Improved Street Sweeping Machine.
1.EDMUND WINKERT of 28 Haupstrasser Longeville near Metz in the Empire
of Germany, Merchant, do hereby declare the nature of the said invention and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
The street sweeping machine forming the subject of the present invention and
illustrated in the accompanying drawings differs advantageously from the ordinary
street sweeping roller in the fact that, contrary to the latter, it receives all the dust
and dirt from the streets into receptacles and thus overcomes the inconvenience
of loss in time connected with the use of the sweeping roller as well as the great
cost involved..
Figure 1 is a side view, Figure 2 a plan Figure 3 a. cross section and Figure 4
a front view of the cart.
Figure 5. is a horizontal section showing the sweeping brush and other parts.
Figure 6. is a side view of the gearing of the brush and
Figure 7 is a longitudinal section and Figure 8 is an end view of the coupling
device..
The cart in the present machine is formed of the two receptacles A and B, one
above the other, the first of which is provided with a sliding door M having a
sight hole L in it, while the latter is provided with a lowering side door
(not shown) for allowing the dirt to be moved from the lower into the upper
receptacle.
The shaft in the rear part of the receptacle A carries the sweeping brush T,
and close to the latter are the boards K mounted on the shaft g. The shaft / is
carried by the rear end of the lever frame G and the shaft g is mounted in bearings
fixed to the bottom of the receptacle A, and is connected by lever and connecting
rod H to the frame G. This arrangement allows the sweeping mechanism to be
put in or out of action from the driver's seat and to be fixed in the required
position by means of the standard P. A screen & surrounding the sweeping
mechanism serves to prevent the sweepings from being scattered about.
In order to retain back in the receptacle A any paper, wood or the like which
may stick to the brush, two rakes d and e with prongs n and n¹ respectively are
provided. The first is supported rigidly in the sides of the cart and is made to
enter deep into the brush, while the latter rake is pivotted and is situated in front
of the fixed rake & when taken in the direction of the rotation of the brush, and is
regulated by a lever N in such a manner that its prongs only just touch the tips
of the brush. The driving mechanism for the brush consists of two pairs of cog
wheels Z, Z, the cog wheels Z, being on the shaft a of the driving wheels E and
the wheels on the shaft of the brush.
The distance pieces J keep the cog wheels in position during the starting or
stopping of the brush. The hubs of the cog wheels Z Z have on their outer side
ratchet teeth into which gear the teeth of the sleeve 1 provided with grooves 2 and
guided by feather 3 in the casing i where the spring 4 keeps it in contact with the
teeth on the hub for the purpose and in such a manner that when the vehicle is
going ahead the brush is revolved while during the backward movement of the cart
the brush is stopped see Figures 7 and 8.
The lower receptacle is provided at the bottom and close to the brush with a trap
door v, which, by being lifted from time to time by the lever handle u', throws
the dust or dirt deposited there by the brush right against the farthest end of the
cart.
To render the machine more effective in dry weather a water tank C with

page_text: sprinkling pipe D and the usual valve is provided under the seat of the driver. If
the lower receptacle gets so far filled that the working of the brush becomes
defective the sweepings can be transferred, after lowering the side door, from
the lower into the upper receptacle. O, O are ventilating shafts communicating
with the lower chamber A.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. A street sweeping machine having a rotating and adjustable sweeping brush
located at the rear part of the vehicle, shovel boards K to pass the dust or refuse
into the receptacle A, superposed receptacles A and B for the reception of the
refuse, a fixed and a moveable rake which can be adjusted to the periphery of the
brush and finally a sprinkling device beneath the drivers seat consisting of the tank C
with a valve through which the water can pass into the perforated pipe D sub-
stantially as herein shown and described.
2. In a street sweeping machine constructed as referred to in Claim 1. the
arrangement of an automatic starting or stopping coupling for the brush consisting
of the sleeve 1 guided by means of a groove 2 and feather 3 in the casing i which
sleeve is kept in gear with the hub of the cog wheel during the forward movement
of the cart by the action of the spring 4 substantially as herein shown and
described.
3. In a street sweeping machine the combination and arrangement of parts.
substantially as herein shown and described.
Dated this 12th day of September 1892.
