page_text: Apparatus for Watering the Streets.
I, JACOB HAUSCHILDT, Merchant, of 32, Gladbacherstreet, of Cologne, in the
Province of Rhineland and Kingdom of Prussia, do hereby declare the nature
of this invention to be as follows:
The present invention relates to a device for watering the streets by stationary
pipes. Similar devices of this kind hitherto known provide stationary coils of
pipes following the direction of the street either on the one or on both sides
of the street near the side-walk, or along the base of the houses or lying in
the side-walk, and having on the side towards the street a number of openings
for sprinkling and actuated by direct connection with the water pipes. In this
arrangement, as can easily be imagined and as has been demonstrated by experi-
ments, disadvantages have shown themselves owing to the following reasons:
1.) When the whole length of the street is watered at once, it is necessary
to open all the hydrants or other connections from the streets or the houses in
order to let the water flow out from all the openings.
2.) Even under the above conditions the water does not come out uniformly
through the openings, but assuredly in greater quantities and with greater force
in those parts which lie near to the hydrants, and with less force or perhaps not
at all at those points which lie farther away from the hydrants.
3.) If the street is to be watered and cleansed in sections, the water, after
the section in question has been opened, must spread itself over all the pipes and
fill them before the sprinkling begins, thus causing, on the one hand, an
unnecessary quantity of water to be used, and on the other, entailing a consider-
able loss of time.
My invention is intended to remove these drawbacks.
In the accompanying drawing Fig. 3 represents a cross-section of a piece of
a street provided with my apparatus, while Figs. 1 and 2 show on a somewhat
larger scale the device in a longitudinal section through the street in a lateral
view and in a view from above on the street.
The improvement as compared with the hitherto known devices consists, on
the one hand, in having the spray pipes not formed of a single continuous coil
of pipes, but of a number of short pipes lying behind one another, each closed
at its head and connected severally, by one or more conducting pipes, with the
main pipe laid in the road; and on the other hand, in having beneath the actual
spray pipe a second pipe for collecting and distributing the water, and which
is connected with the main water pipe in the road, whilst it itself is in connection
with the actual spray pipe by means of a number of short pipes turned upwards
distributed over the whole length of the pipe in such a manner that the water
is conducted to the spray pipe throughout its whole length evenly, that is, is
so distributed, that at every part of the pipe from one end to the other all the
holes of the spray are plentifully supplied with water with suitable pressure,
so that the water flows out in equal jets.
In the accompanying drawing A represents the spray pipe laid near the curb

page_text: of the side-walk O, E the main water pipe in the road, D the conducting pipe
branching from the latter to the spray-pipe A, with a slide F built in to enable
the water to be cut off, B the secondary pipe beneath A serving as collecting
and distributing basin, and C the short distributing and connecting pipes
between A and B.
On opening the slide F the water therefore flows out from the conductor E
through the cross-pipe D into the pipe which serves as collecting basin, com-
pletely filling the latter, and thus rises, through the several short connecting
pipes C distributed throughout the length of the pipes A and B, up into A,
so that the supply of water to the latter takes place simultaneously throughout
the whole length, and with equal pressure, and consequently the water flows
out in equal jets from all the spray holes, or slits, band that the more strongly
the more the slide F is opened, and vice versa.
The equal distribution of the flow of the water, that is, of the pressure upon
the whole length of the pipe A commencing from the basin B, through the short
connecting pipes C, may be effected in two ways, as shown in Figs. 1 and 2 of
the drawing, in their right and left halves. Either all the connecting pipes C
have an equal diameter (as shown in the left half of Figs. 1 and 2) but are not
placed at equal distances from each other from the entrance of D to the closed
ends of the pipes B and A, but become gradually closer together, or else, (as
shown in the right half of Figs. 1 and 2) the pipes C are arranged at equal
distances from each other throughout the length between the entrance of the
supply pipe D and the closed ends of B and A, but increase gradually in diameter
towards the ends of A and B, so that close to this end where otherwise the pressure
would begin to diminish, the supply of water will be more plentiful and conse-
quently the pressure higher, than at the centre, whereby a rapid and equal distri-
bution of water and of pressure throughout the whole length of the pipe A, and
consequently equal jets of water from all the spray holes b, will be secured.
The key to the slide may conveniently be kept, as shown in Fig. 3, locked
in a box G attached to the wall of the house, and the key of the box may be
in charge of a special workman, or of the watchman on beat, or of any other
suitable town official, so that the slide F may be opened or closed by him at
pleasure, or when required, and thus the spray apparatus may be set at work.
It goes without saying that the connection between the main water pipe E
and the pipe B could be effected by several cross-pipes, instead of by a single
one, in which case, as in the method of construction, shown in the drawing, the
distribution of water from the junction of D with the pipe B down to the lower
end would take place through pipes C of equal size placed gradually closer to each
other, these to be placed between each pair of the cross-pipes D emptying them-
selves into the same pipe B.
Naturally there might be a combination of the arrangement on the left half
of Figs. 1 and 2 with that on the right half, so that in this case the short
connecting pipes C between the pipes A and B would not only be placed gradually
nearer to one another, but their diameter would also be gradually increased.

page_text: of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
The present invention relates to a device for watering the streets by stationary
pipes. Similar devices of this kind hitherto known provide stationary coils of
pipes following the direction of the street either on the one or on both sides
of the street near the side walk, or along the base of the houses or lying in
the side-walk, and having on the side towards the street, a number of openings
for sprinkling and actuated by direct connection with the water pipes. In this
arrangement, as can easily be imagined and as has been demonstrated by experi-
ments, disadvantages have shown themselves owing to the following reasons:
1.) When the whole length of the street is watered at once it is necessary
to open all the hydrants or other connections from the streets or the houses in
order to let the water flow out from all the openings.
2.) Even under the above conditions the water does not come out uniformly
through the openings, but assuredly in greater quantities and with greater force
in those parts which lie near to the hydrants, and with less force or perhaps not
at all at those points which lie farther away from the hydrant.
3.) If the street is to be watered and cleansed in sections the water, after
the section in question has been opened, must spread itself over all the pipes and
fill them before the sprinkling begins, thus causing, on the one hand
unnecessary quantity of water to be used, and on the other entailing a consider-
able loss of time.
My invention is intended to remove these drawbacks.

In the drawing filed with the Provisional Specification Fig. 3 represents a
cross-section of piece of a street, provided with my apparatus, while Figs. 1
and 2 show on a somewhat larger scale the device in a longitudinal section
through the street in a lateral view and in a view from above on the street.
The improvement as compared with the hitherto known devices consists, on
the one hand, in having the spray pipes not formed of a single continuous coil
of pipes, but of a number of short pipes lying behind one another, each closed
at its head and connected severally, by one or more conducting pipes, with the
main pipe laid in the road; and on the other hand, in having beneath the actual
spray pipe a second pipe for collecting and distributing the water and which
is connected with the main water pipe in the road, whilst it itself is in connection
with the actual spray pipe by means of a number of short pipes turned upwards
distributed over the whole length of the pipe in such a manner that the water
is conducted to the spray pipe throughout its whole length evenly, that is, is
so distributed, that at every part of the pipe from one end to the other all the
holes of the spray are plentifully supplied with water with suitable pressure,
so that the water flows out in equal jets.
In the drawing A represents the spray pipe laid near the curb of the side-
walk 0, E the main water pipe in the road, the conducting pipe, branching
from the latter to the spray-pipe A, with a valve F built in to enable the water
to be cut off, B the secondary pipe beneath A serving as collecting and distribut-
ing basin, and C the short distributing and connecting pipes between A and B.
On opening the valve F the water therefore flows out from the conductor E
through the cross-pipe D into the pipe B-which serves as collecting basin, com-
pletely filling the latter, and thus rises, through the several short connecting
pipes C distributed throughout the length of the pipes A and B, up into A,
so that the supply of water to the latter takes place simultaneously throughout
the whole length, and with equal pressure, and consequently the water flows
out in equal jets from all the spray holes, or slits band that the more strongly
the more the valve F is opened and vice versa.
The equal distribution of the flow of the water, that is, of the pressure upon
the whole length of the pipe A commencing from the basin B, through the short
connecting pipes C, may be effected in two ways, as shown in Figs. 1 and 2 of
the drawing, in their right and left halves. Either all the connecting pipes C

page_text: have an equal diameter (as shown in the left half of Figs. 1 and 2) but are not
placed at equal distances from each other from the entrance of 1) to the closed
ends of the pipes B and A, but become gradually closer together, or else, (as
shown in the right half of Figs. 1 and 2) the pipes C are arranged at equal
distances from each other throughout the length between the entrance of the
supply pipe I and the closed ends of B and A, but increase gradually in diameter
towards the ends of A and B, so that close to this end where otherwise the pressure
would begin to diminish the supply of water will be more plentiful and conse-
quently the pressure higher, than at the centre, whereby a rapid and equal distri-
bution of water and of pressure throughout the whole length of the pipe A, and
consequently equal jets of water from all the spray holes 6 will be secured.
The key to the valve F may convenientiy be kept, as shown in Fig. 3, locked
in a box G attached to the wall of the house, and the key of the box may in
change of a special workman, or of the watchman on beat, or of any other suitable
town official, so that the valve F may be opened or closed by him at pleasure,
or when required, and thus the spray apparatus may be set at work.
It goes without saying that the connection between the main water pipe E
and the pipe B could be effected by several cross-pipes, instead of by a single
one, in which case as in the method of construction, shown in the drawing the
distribution of water from the junction of D with the pipe B down to the lower
end would take place through pipes C of equal size placed gradually closer to each
other, these to be placed between each pair of the cross-pipes D emptying them-
selves into the same pipe B.
Naturally there might be a combination of the arrangement on the left half
of Figs. 1 and 2 with that on the right half so that in this case the short
connecting pipes C between the pipes A and B would not only be placed gradually
nearer to one another, but their diameter would also be gradually increased.
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::
--
Apparatus for watering the streets, thereby characterized, that between the
spray pipe A closed at both ends and lying in the side walk of the street, and
the supply pipe D branching from the main water pipe in the road, a larger
pipe B is arranged likewise closed at both ends, and serving as a basin for collect-
ing and distributing the water, and lying under the spray pipe A, and connected
with this by a number of short vertical pipes C, distributed over the whole length
of the pipes A and B in such a manner that the water is supplied the more
distant from the middle of the length of the pipe A, the more plentiful and with
higher pressure towards the ends of A, for the purpose of securing a rapid and
equal distribution of water and of pressure throughout the whole length of the
pipe A and consequently equal jets of water from all the spray holes of the
pipe A, the pipes C either being all of the same diameter but standing nearer
to each other from the middle towards the ends of the pipe A, or increasing in
diameter from the middle to the ends of the pipe A but standing at equal dis-
tances from each other.
