Improvements in Apparatus for Watering Streets and for similar
purposes.
I, ARTHUR ROGERS JENKINS, of 163, Wool Exchange, in the City of London,
Merchant, do hereby declare the nature of this invention to be as follows:-
My invention relates to apparatus for the distribution of water for watering
streets and for similar purposes, and is chiefly designed to improve the construc-
tion and increase the efficiency of that kind or class of such apparatus known as
watering-carts, so as to enable the same to distribute the water uniformly and
with a rapid flow over a large area, even with only a small head of water in the
tank.
According to my said invention, I arrange one or more pipes or conduits in com-
bination with the tank of the watering-cart in such a manner that the said pipes
or conduits open at their forward end into the said tank at or near the centre
thereof, and extend backward, preferably beneath the axle-tree of the rear wheels,
to or beyond the rear end of the cart. Each pipe or conduit is provided with
a conical or funnel-shaped extension which terminates in a sprinkling-rose or other
suitable distributing device, or in a pipe of smaller diameter provided at its rear
end with a distributing device. Within each of the said pipes or conduits is
arranged a shaft having mounted thereon a screw-propeller of similar construction
to those employed in the propulsion of ships, or of other suitable shape, or a wheel
provided with vants of any convenient description. The said shaft is mounted
in suitable bearings and extends through a stuffing-box in the pipe or conduit,
and is connected, through bevel wheels, a driving-chain and sprocket-wheels,
or through other suitable gearing, with one or other of the wheels of the vehicle,
preferably the rear-wheels, so that, as the said cart is drawn along, the screw-
propeller will force the water along the pipe or conduit and through the rose
or other distributing device, from which it will be discharged at a high velocity
onto the surface to be watered.
The said rose or other distributing device is preferably fitted with a movable
cap or caps or other suitable devices for enabling the attendant to adjust the
same so as to distribute the water only in the direction or directions where it
is required.
By using a rose with very fine apertures or pin-holes and obtaining, by means
of the screw-propeller, a considerably increased head or pressure of the water, I
ensure the distribution of the water very rapidly over a large area of surface,
without increasing the height of the tank; and, by dispensing with the long
perforated pipes heretofore employed, I obviate to a great extent the liability to
leakage and to uneven or irregular distribution of the water.
The aperture connecting the tank with each pipe or conduit is controlled by

page_text: means of a suitable valve, the operating lever or handle of which is arranged within
easy reach of the attendant.

Improvements in Apparatus for Watering Streets and for similar
purposes.
I, ARTHUR ROGERS JENKINS, of 163, Wool Exchange, in the City of London,
Merchant, 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:-
-
My invention relates to apparatus for the distribution of water for watering
streets and for similar purposes, and is chiefly designed to improve the construc-
tion and increase the efficiency of that kind or class of such apparatus known as
watering-carts, so as to enable the same to distribute the water uniformly and
with a rapid flow over a large area, even with only a small quantity or head of
water in the tank.
According to my said invention, I arrange one or more pipes or conduits in com-
bination with the tank of the watering-cart in such a manner that the said pipes
or conduits open at their forward end into the said tank at or near the centre
thereof, and extend backward, preferably beneath the axle-tree of the rear wheels,
to or beyond the rear end of the cart. Each pipe or conduit is provided with
a conical or funnel-shaped portion which terminates in a sprinkling-rose or other
suitable distributing device, or in a pipe of smaller diameter provided at its rear
end with a sprinkler or distributing device. Within each of the said pipes or con-
duits is arranged a screw-propeller similar to those employed in the propulsion of
ships, or of other suitable shape, or a wheel provided with vanes of any convenient
description, which propeller or wheel is fixed upon a shaft mounted in suitable
bearings and extending through a stuffing-box in one end of the pipe or conduit
This shaft is connected through the medium of bevel-wheels, a driving-chain and
sprocket-wheels, or through other suitable gearing, with one or other of the wheels
of the vehicle, preferably one of the rear-wheels, so that, as the said cart is drawn
along, the screw-propeller or its equivalent will be rapidly rotated and will force
the water along the pipe or conduit and through the rose or other distributing
device, from which it will be discharged at a high velocity on to the surface to
be watered.
The said rose or other distributing device is preferably fitted with a movable
cap or caps or other suitable devices for enabling the attendant to adjust the
same so as to distribute the water only in the direction or directions where it
is required.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice."

is the tank of the watering-cart; 6 is a cylindrical chamber or conduit com-
municating near its forward end through a pipe c with the said tank a, and

page_text: having at its rear end a taper or conical portion d from which a pipe e extends
rearwardly. This pipe e terminates in a sprinkling-rose f. In the said chamber
or conduit 6 is mounted a rotary shaft g on which is fixed a screw-propeller h.
This shaft is connected by bevel gear-wheels j, k, with a transverse shaft which
is driven from the hub of one of the rear travelling-wheels w, through the medium
of sprocket-wheels m, n and an endless chain p.
The relative dimensions of the screw-propeller hand of the chamber or conduit b
in which it works, as well as the pitch of the screw-propeller and the velocity of
its motion are so proportioned and regulated as to ensure the production of a
pressure of water in the pipe e sufficient to force the water through the rose f to
a considerably greater distance than would be practicable with the head or
presure usually obtained in watering-carts.
To enable the attendant to control the direction in which the water shall be
thrown from the sprinkling-rose f, I sometimes provide the said rose with an
adjustable cap g, Figure 2, which is pivoted at to a ring s secured upon the
said rose in such a manner that it can be turned about its axis to vary the
direction in which the water is to be projected. The cap q can also be turned
about its pivot r for this purpose. I can, if desired, provide two of these adjustable
caps both pivoted at r to the ring s. Or the said ring may be dispensed with, if
desired, and the cap or caps be pivoted directly to the rose itself.
By using a rose with very fine apertures or pin-holes and obtaining, by means
of the screw-propeller, a considerably increased head or pressure of the water, I
ensure the distribution of the water very rapidly over a large area of surface,
without increasing the height of the tank; and, by dispensing with the long
perforated pipes heretofore employed, I obviate to a great extent the liability to
leakage and to uneven or irregular distribution of the water.
The aperture connecting the tank with the pipe c is controlled, as usual, by means
of a suitable valve, the operating lever or handle of which is arranged within
easy reach of the attendant.
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:-
First. An apparatus for the distribution of water for watering streets and for
similar purposes, in which a screw-propeller or equivalent contrivance works in a
chamber or conduit communicating at one end with the water-tank, and at the
other with a distributing device, substantially as, and for the purpose, herein-
before described.
Second. A watering-cart provided with my improved apparatus constructed
substantially as described with reference to Figure 1 of the drawing and for the
purpose specified.
Third. The combination, with the sprinkling-rose, of one or more adjustable
caps, substantially as described and for the purpose specified.
