1 JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents, do hereby declare the nature of this invention to be
as follows:-
This invention relates to means for transmitting the rotary movement of the wheel
or wheels of a cart or vehicle to any device or part to be put in rotary motion in or on
the cart, as in the case for instance in water carts in which the water is separated and
thrown out over a large breadth of the street by quickly revolving centrifugal discs or
similar devices. If this transmission of rotary movement is derived from the cart
wheels directly by spur wheel gearing (so as to avoid the use of chain transmission
and as far as possible the employment of bevil wheels) there will be a permanent
change in the theoretical position of the pitch lines between those two spur wheels the
one of which is carried by the cart wheel, and is therefore independent of the cart
springs, and the other is carried by the cart frame, and is therefore dependent upon
the movement of the cart springs. This change of the theoretical positions of the
pitch lines between the two spur wheels will be caused by the variations of load upon
the cart springs and by sudden shocks or vibrations of the loads upon the springs.
Such change of the theoretical position of the pitch lines is liable to cause distur-
bances, breakage, &c.
In order therefore to keep the theoretical position of the pitch lines between the
two wheels as constant as possible, I adopt the following arrangement which I will
describe as applied to a water cart, the reservoir and frame of which rest partly by
means of springs upon the axle of the hind wheels of the cart. One of the hind
wheels is provided with a spur wheel taking into a spur pinion or wheel carried by
the frame.
It is the theoretical position of the pitch lines of these two spur wheels

page_text: which should remain unchanged under varying loads upon the springs and under
vibrations of such load. For this purpose the shaft, which the spur pinion actuates, is
carried by a bearing, which is arranged at the underside of the side beam of the cart and
is capable of being shifted in the direction of such beam. Against the underside or lower
surface of this bearing the free end of the cart spring bears; this spring if extended by the
load will shift or slide on the said lower surface. The spring, in its sliding movement is
guided between two plates fixed to said bearing one of which shifts the bearing by means
of a rod and a link in the longitudinal direction of the cart beam. The said rod is
connected movably with its one end to the cart axle and with its other end to the link.
The link is hinged to the cart beam and is connected at a certain point to the plate by
means of a bolt. From this arrangement it follows, that if the length of the rod and
link are in due proportions, each ascent or descent or up and down movement of the
beam under the influence of the varying load will cause a shifting of the bearing
longitudinally of the beam; such shifting will be towards the hind axle, if the beam
rises, while it will be away from the hind axle if the beam descends. The shifting
however will always be such, that the theoretical position of the pitch lines between the
spur wheel and spur pinion is maintained. In order to conpensate at the other end of
the pinion shaft for the shifting of the spur pinion with the bearing, the shaft is
mounted, at the other end, in a suspended bearing which is capable of turning around
its vertical axle; the taking of the bevil wheel on this end of said shaft into the bevil
wheel on the shaft of the centrifugal discs is of course not disturbed by the alteration
in the position of the pinion shaft caused by the shifting of the bearing. A lever and
a connecting rod are provided for throwing the spur pinion into or out of gear with
its shaft.
The improved mechanism above described for transmitting the rotary motion of the
cart wheel is combined with or employed for a centrifugal device for watering
purposes. This device consists mainly of a centrifugal wheel provided with blades and
fixed upon the shaft of the bevil wheel, above referred to, this shaft being mounted in a
sleeve or bearing, fixed in any suitable manner to the cart frame. The centrifugal
wheel is rotated at high speed by the mechanism specified between two fixed discs,
the water from the reservoir being led by a pipe to the space between the two discs
where it is caught by the blades of the centrifugal wheel and thrown by this wheel in
a divided state over a large area of the street to be watered.
That part of the space between the discs which is deepest and situated towards the
cart is closed by a metallic sheet, so that no water can escape in that direction. The
pipe may terminate at the upper disc in a curved gutter, closed at top and open below
so as to direct the water from the reservoir upon a larger surface of the centrifugal
wheel.

I, JOHN CLAYTON MEWBURN, formerly of 169, Fleet Street in the City of London,
but now of 55 and 56 Chancery Lane, London, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this invention and in what manner the sanie
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to means for transmitting the rotary movement of the wheel
or wheels of a cart or vehicle to any device or part to be put in rotary motion in or on
the cart, as is the case for instance in water carts in which the water is separated and
thrown out over a large breadth of the street by quickly revolving centrifugal discs or
similar devices. If this transmission of rotary movement is derived from the cart
wheels directly by spur wheel gearing (so as to avoid the use of chain transmission
and as far as possible the employment of bevil wheels) there will be a permanent
change in the theoretical position of the pitch lines between those two spur wheels the
one of which is carried by the cart wheel and is therefore independent of the cart
springs, and the other is carried by the cart frame and is therefore dependent upon
the movement of the cart springs. This change of the theoretical positions of the
pitch lines between the two spur wheels will be caused by the variations of load upon
the cart springs and by sudden shocks or vibrations of the loads upon the springs.
Such change of the theoretical position of the pitch lines is liable to cause distur-
bances, breakage, &c.
In order, therefore, to keep the theoretical position of the pitch lines between the
two wheels as constant as possible I adopt the following arrangement which I
will describe as applied to a water cart. Figure 1 illustrates in side elevation,
Figure 2 in end elevation and Figure 3 in plan. The reservoir a and frame b of the
cart rest partly by means of springs c upon the axle d of the hind wheels of the cart.
One of the hind wheels e is provided with a spur wheelf taking into a spur

of the pitch lines of these two spur wheels ƒ and g which should remain
unchanged under varying loads upon the springs and under vibrations of such
load. For this purpose the shaft h, which the spur pinion g actuates, is carried by a
bearing i, which is arranged at the underside of the side beam k of the cart and is
capable of being shifted in the direction of such beam. Against the underside or lower
surface of this bearing the free end of the cart spring c bears; this spring, if
extended by the load will shift or slide on the said lower surface. The spring, in its sliding
movement is guided between two plates fixed to said bearing, one of which 1, shifts the
bearing i by means of a rod m and a link n in the longitudinal direction of the cart
beam. The rod m is connected movably with its one end to the cart axle d and with
its other end to the link n. The link n is hinged to the beam k and is connected at a
certain point to the plate by means of a bolt. From this arrangement it follows that

page_text: 'if the lengths of the rod m and link n are in due proportions each ascent or descent or
up and down movement of the beam k under the influence of the varying load will
cause a shifting of the bearing i longitudinally of the beam k; such shifting will be
towards the hind axle if the beam rises, while it will be away from the hind axle if
the beam descends. The shifting, however, will always be such that the theoretical
position of the pitch lines between the spur wheel and spur pinion g is sufficiently
maintained.
In order to compensate at the other end of the pinion shaft for the shifting of the
spur pinion g with the bearing the shaft is mounted at the other end in a
suspended bearing o which is capable of turning around its vertical axis; the taking
of the bevil wheel p on this end of said shaft into the bevil wheel 9 on the shaft of the
centrifugal discs is of course not disturbed by the alteration in the position of the
pinion shaft caused by the shifting of the bearing i. A lever and a connecting
rods are provided for throwing the spur pinion g into or out of gear with its shaft h.
For the proper working of the device or arrangement described the distances x y z
longitudinally of the shaft h should be proportionate to the distances of the
pivoty in the link n.
In Figures 2 and 3 the improved mechanism above described for transmitting the
rotary motion of the cart wheel is combined with or employed for a centrifugal device
for watering purposes. This device consists mainly of a centrifugal wheel & provided
with blades and fixed upon the shaft of the bevil wheel above referred to, this shaft
being mounted in a sleeve or bearing u fixed in any suitable manner to the cart frame.
The centrifugal wheel is rotated at high speed by the mechanism specified between
two fixed dises and w which are fixed to the sleeve i the water from the reservoir a
being led by a pipe t to the space between the two discs v and to where it is caught by
the blades of the centrifugal wheel ' and thrown by this wheel in a divided state over
a large area of the street to be watered.
That part of the space between the discs and w which is deepest and situated
towards the cart is closed by a metallic sheet so that no water can escape in that
direction. The pipe t may terminate at the upper disc v in a curved gutter, closed at
top and open below so as to direct the water from the reservoir upon a larger surface
of the centrifugal wheel.
Having now particularly described and ascertained the nature of the said invention
as communicated to me and in what manner the same is to be performed, I declare
that what I claim is :-
1. In water carts and other vehicles in which the rotary movement of one of the
vehicle wheels is transmitted to a rotating device mounted on the vehicle frame, making
movable the bearing of the wheel or pinion g, this wheel or pinion being carried by
the vehicle frame and rotated by the spur wheel fof the vehicle wheel, the amount that
such bearing shifts corresponding to the increase or decrease of the load so that the
theoretical position of the pitch lines between ƒ and g is sufficiently maintained,
substantially as and for the purpose set forth.
2. In combination with the arrangement specified in Claim 1, mounting the shaft h
of the wheel or pinion g in a second bearing, capable of turning on its vertical axis,
substantially as and for the purpose set forth.
3. In combination with the arrangement specified in Claims 1 and 2, a centrifugal
wheel on the shaft of the bevil wheel q, which centrifugal wheel, rotating between
two fixed discs v and w, throws out the water that flows from the reservoir a over a large
breadth of the street to be watered, and in a divided state, substantially as set forth.
