Improvements in Street Sprinklers.
We, FREDERICK WINKLER and LENHART WINKLER, both of South Bend,
County of St. Joseph, State of Indiana, United States of America, Manufacturers
do hereby declare the nature of our said invention to be as follows:-
The object of our invention is to simplify the construction of street sprinklers and
to facilitate the operation of the valves and the adjustment of working parts; our
improved street. sprinkler being also self-cleaning and not liable to flood the
streets.
In carrying out our invention we mount a tank, of suitable shape and proportions,
upon a frame fitted with wheels in the usual manner. To the underside of the
frame we attach one, two or more cylinders, which are connected with the tank by
suitable pipes for the supply of water. The cylinders are perforated, preferably on
the underside, for about half the circumference and half the length for the outflow
of the water, which outflow is controlled by a watertight plunger, operated by
means of levers, connecting rods or other devices from the footboard by the driver.
A hole or slot is cut in the cylinder behind the plunger for the purposes of self
cleaning and of admitting a spanner for adjusting the packing of the plunger.
The plunger is fitted with a segmental pressure regulator to prevent the lower
apertures receiving too great a pressure and outflow of water.

Improvements in Street Sprinklers.
FREDERICK WINKLER and LENHART WINKLER, both of South Bend, County
of St. Joseph, State of Indiana, United States of America, Manufacturers, do
hereby declare the nature of our 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 object of our invention is to simplify the construction of street sprinklers,
and to facilitate the operation of the valves, and the adjustment of the working
parts; our improved street sprinkler being also self-cleaning and not liable to flood
the streets.
In carrying out our invention we mount a tank, of suitable shape and proportions,
upon a frame fitted with wheels in the usual manner. To the underside of the
frame we attach one, two or more cylinder or cylinders, which is or are connected
with the tank by suitable pipes for the supply of water. The cylinders are
perforated, the perforations extending to about half the circumference and half the
length of the cylinder, for the outflow of the water, which outflow is controlled by
a watertight plunger or piston fitted with a rubber piston ring. The piston is
operated by means of levers, connecting rods, or other devices from the footboard
by the driver. A hole or slot is cut in the cylinder for the purposes of self-cleaning,
and of admitting a spanner for adjusting the packing of the plunger.
The plunger is fitted with a segmental pressure regulator to intercept some of the
lower apertures, and prevent some of such apertures receiving too great a pressure
and to limit and control the outflow pressure of water.

And in order that our said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
figures of reference indicate corresponding parts.
Figure 1 is a side elevation of a street sprinkling machine, with our improved
sprinkling device fitted thereto.
Figure 2 is a plan view of our sprinkling attachment, fixed to the underside of
the bed frame, with the operating rods.
Figure 3 is a rear view, showing the method of attaching the sprinkling device to
the frame.

Figure 4 is a longitudinal sectional elevation of one of the sprinklers.
Figure 5 is an elevation, partly in section showing the position of the regulator,
attached to the plunger or piston, for partially shutting off the outflow.
Figure 6 is a section on the line 1-2 of Figure 5.
3 is the tank or receptacle for water, which may be of any suitable construction,
and which forms no part of our invention. 4 is a rubber hose connecting the tank 3
with the sprinkling cylinder 5. 6 is a flat steel spring fastened to the front end of
the tank 3, & bent at the lower end as shown at 7, which draws the lever 13 inwards
when released by the driver.
8 is a treadle plate for the driver's foot by means of which the driver regulates
the flow of water. The foot plate is carried by the lever 13 which can be fixed in
any position by means of notches cut in the foot board 9. The rod 10 is pivoted to
the rod 13 and also to the lever 11, the lever 11 being pivoted to the rod 12 of the
piston or plunger 14. The cylinder 5 is mounted so that it may be turned round
by hand in its covers 16 to 21. The cylinder is perforated with a number of holes,
as shown at 15.
The pipes are coupled to the cylinders 5 so as to be readily removed for
cleaning &c. The piston rod 12 passes through a hole formed in the cylinder
cover 16. 17 is a wash-out hole, for the purpose of cleaning out the cylinder, which
is effected by passing the piston over the hole 17 towards the cover 16, as shown by
dotted lines in Figure 4. The piston or plunger 14 can be caused to assume any
position lengthwise in the cylinder 5, by means of the treadle 8 and its connections,
and this increase, reduce, or cut off the supply of water. The driver can also by
moving the piston to the position shown by dotted lines in Fig. 4, wash out the tank.
The wash-out hole 17, is also useful for the insertion of a spanner to tighten up the
nuts on one or both side or sides of the piston, and thus expand the rubber washer
of the piston 14.
The cylinders are preferably formed of brass, and are fixed to the framing by
bolts 19, so as to be capable of adjustment as to height.
The piston 14 is fitted with a water check 20, consisting of a segmental block
covering a portion of the internal surface of the cylinder, as shewn in Figs. 5
and 6.
;י
By means of this block the holes 15 may be more or less covered, and the
sprinkling may be increased or diminished and thrown in any required direction.
The inner end of the piston-rod 12 is screw threaded, and the piston 14 consists
of a rubber washer, confined between two cast iron washers, and these latter secured
in position by two nuts, by which the rubber washer can be compressed, and caused
to expand radially as shewn in Fig. 4.
[
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
'claim is
1. In the construction of street sprinklers the combination of brass cylinders,
perforated and fastened to the under side of the frame by rods 19 in front of the
rear wheels to which the water is conveyed by rubber hose 4 connected with the
bottom of the tank substantially as herein before described and illustrated by
the drawings.

2. In the construction of street sprinklers the combination of one or more brass

page_text: perforated cylinder or cylinders 5, fastened to the underside of the frame in front
of the rear wheels connected with a tank 3 by rubber-hose, and having a flange cap,
or cover 21 at one end to join the hose, and a flange cap or cover 16 at the other
end, through which the piston-rod 12 works, substantially as hereinbefore described
and illustrated by the drawings.
3. In the construction of street sprinklers, the combination of brass perforated
cylinders, fastened to the under-side of the frame in front of the rear wheels
connected with the tank 3 by rubber hose, and having a flange cap or cover 21 at
one end to join the hose, and a flange cap or cover 16 at the other end, through
which the piston-rod 12 works, to which rod the piston or plunger is fastened, the
inner end of the rod 12 being screw threaded, and carrying a rubber-washer confined
between two iron washers, and the latter secured in position by two nuts, which
nuts when tightened expand the rubber washer, and make a perfectly tight piston
valve, substantially as herein before described and illustrated by the drawings.
4. In the construction of street sprinklers as aforesaid, the combination therewith
of a segmental regulator 20, attached to or cast in one with a washer of the piston
valve 14, whereby the sprinkling may be directed and spread where necessary, and
whereby the water escaping from the lower part of cylinder, may be diminished,
substantially as herein before described and illustrated by the drawings.
5. The construction of a piston plunger which works to and fro in the cylinder,
and by which a light or heavy spray may be given, by means of the operating rods,
substantially as, and for the purposes hereinbefore described and illustrated by the
drawings.
6. The construction of a cylinder having a wash-out hole 17, with a piston
plunger which acts and makes a self cleaner by the use of the operating rods,
hole 17 being large enough to let pebbles or other substances which may get into
the sprinkler escape.
The same hole being large enough and in such a position that
the piston-nuts can be tightened, substantially as and for the purposes described and
illustrated by the drawings.
7. The combination of a spring 6, 7, fastened to the front of the tank by means of
a flat bar of iron, which keeps the spring in its place, the spring operating so as to
keep the valve shut, when sprinkling is discontinued, substantially as hereinbefore
described, and illustrated by the drawings.
8. The general construction, arrangement and combination of the several and
respective parts, together forming our invention of improvements in street sprinklers,
substantially as herein before described, and illustrated by the drawings.
