PROVISIONAL SPECIFICATION.
Improvements in or connected with Road Locomotives for
Agricultural and other Purposes.
I, PHILIP JOSEPH PARMITER, of The Harrow Works, Ansty, near Salisbury, in
the County of Wilts, Engineer, do hereby declare the nature of this invention
to be as follows: -
My invention has for its chief object to provide a locomotive for common roads
which may be used either for steam cultivating purposes, for transporting agricul-
tural and other produce or material from place to place or as a road roller, and it
comprises the improvements hereinafter described; a part of my improvements,
however, is also applicable to motor cars and like vehicles in cases where it is
advantageous to carry a large supply of water.
According to my invention I provide a locomotive boiler, the front or smoke
box end of the said boiler being carried in the usual manner whilst the driving
wheel which is in the form of a roller is arranged immediately behind the boiler
and mounted upon an axle supported in arms or brackets projecting rearwardly
from the boiler. The fire box door is arranged at one side of the fire box and
the tender is also carried upon the side of the boiler. The said main axle projects
beyond the said arms or brackets and has mounted upon it the rope winding drums
necessary for steam cultivation. The motion of the engine, which is mounted
upon the top of the boiler or otherwise suitably arranged, is communicated to
the main axle through suitable gearing and means are provided whereby the said
axle may be connected with or disconnected from the said main wheel or roller.
When the locomotive is travelling, the said main wheel is locked to the gear
wheel fixed upon the main axle, when the winding drums are being used, the said
gear wheel and main wheel are disconnected. Upon the axle are fixed two arms
which rotate therewith, the said arms carrying pawls which can be engaged with
and disengaged from the interior surfaces of the drums when required and the
said arms also carry brakes for checking the rotation of the drums when this
rotation is due to the unwinding of the slack rope.
The box or receptacle in which the goods to be transported are placed, is
pivotally mounted in the rear ends of the arms in which the main axle is carried
and extends over the top of the main wheel or roller in such a manner that
when a pawl or leg on the underside of the said receptacle is placed in engage-
ment with the periphery of the main wheel or with a special wheel and the engine
backed, the said receptacle will be tipped.
Upon the front wheel axle of the engine is mounted a beam or frame carrying
pulleys or rollers over which the ropes are led, the said beam or frame being
capable of taking a lateral movement so as to permit of the rope being prevented
from piling upon the drums when being wound thereon.
In practice I prefer to make the main or travelling wheel in the form of a
water tank so that it may, if desired, carry a reserve supply of water in addition
to that which is arranged in a tank placed under the foot plate of the tender.

page_text: In order that this reserve may be drawn off as desired I arrange in one side of the
tank near the boss a discharge pipe which rotates with the wheel, the said dis-
charge pipe moving with its open end or nozzle around a circular channel fixed
on the adjacent arm or bracket through which the main axle passes in such a
manner that the water as it flows out of the tank will enter the said channel and
gravitate thence into the tank under the foot plate. So long as the water level
is above the top of the said discharge pipe the water will flow through the same
by gravity. To provide, however, for raising the water when below the level of
the said pipe, I provide a kind of scoop or chamber which, during each revolution
is more or less filled with water, which, as the wheel rotates, is lifted and thence
flows through the pipe. A special pipe or nozzle is arranged on the tank, to
which pipe a water lifter can be connected for filling or emptying the tank when
occasion requires.
Although I have described this part of my invention as applied to a road
locomotive, it is to he understood that the arrangement of a reserve water tank
can be applied to motor carriages and other vehicles on which it is desired to
carry a supply of water.
The said roller wheel has the central portion of its periphery fitted with cross
bars whilst the edge portions are left plain and level with the outer surfaces of the
said cross bars, this arrangement of cross bars permitting of obtaining a good
grip upon the ground for driving the wheel, whilst the plain portions at the
edges permit of the wheel skidding when turning corners. The cross bars are,
in some cases, made of india rubber thereby ensuring a perfect grip upon the
ground and reducing oscillation and jolting when travelling.
When the locomotive is being used as a road roller, cylinder segments may be
applied to the surface of the roller for making the same smooth or plain throughout.
I advantageously arrange in connection with the water tank under the foot
plate a water sprayer or distributer, which is adapted to deliver the water upon
the road just in front of the main wheel.

Improvements in or connected with Road Locomotives for
Agricultural and other Purposes.
I, PHILIP JOSEPH PARMITER, of The Harrow Works, Ansty, near Salisbury, in
the County of Wilts, Engineer, 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 has for its chief object to provide a locomotive for common roads
which may be used either as a road roller or for transporting agricultural and
other produce or material from place to place, or for steam cultivating purposes,
and it comprises the improvements hereinafter described; a part of my improve-
ments, however, is also applicable to motor cars and like vehicles in cases where
it is advantageous to carry a large supply of water.
In the accompanying drawings:
Figure 1 is a side elevation of a road locomotive, having my improvements
applied to it:

page_text: Figure is a plan of the same with the up wagon removed;
Figure 3 is a section on the line 3-3 of Figure 1:
Figures 4 and 5 are respectively a sectional front elevation and a side elevation
illustrating a modification.
According to my invention I provide a locomotive boiler a the front or smoke
box end of which is carried in the usual manner upon wheels b, b whilst the rear
end is carried by a roller c which also forms the driving wheel, the said roller
being loosely mounted upon an axle & carried in suitable bearings in the
brackets e, e (the rear ends of which are connected by a tie bar e¹) secured to
the rear end of the boiler. The fire box is arranged to be fed from one side of
the latter and the tender is also placed at the side, as clearly shewn in Figures 1
and 2; f being the tender which is provided with a coal bunker f¹ and with a
water tank beneath it and being the fire box door.
The motion of the engine which in the drawings is represented as being
carried upon the top of the boiler is transmitted to the main axle d through a
train of gear wheels in the usual manner; as shewn the motion is transmitted
from a pinion i upon the crank shaft to a wheel carried upon a shaft k and having
fixed to it a pinion and from the pinion through the intermediate wheel
mounted on a spindle to the main gear wheel secured to the axle d.
The pinion has attached to it or formed in one with it a pinion of slightly
larger diameter and the wheel has formed with it or attached to it a wheel j
of slightly smaller diameter with which the pinion is adapted to engage, the
said double pinion i, being adapted to move longitudinally upon the crank
shaft of the engine through the medium of a lever so that the pinions i, may
be out of gear with their respective wheels j, j', as shewn in the drawing, (in which
position no movement is imparted to the driving axle) or be moved to place
the pinion and wheel j in gear for a slow speed or the pinion and wheel j¹ in
gear for a quicker speed. The main gear-wheel + is adapted to be connected with
the roller wheel c by a pin m, as shewn in Figure 3, the removal of which pin
enables the wheel and the axle d. to rotate without imparting motion to the roller
wheel c.
i
It will be obvious that the apparatus, as thus far described, is, when the roller c
has a smooth surface, suitable for use as a road roller.
27.
When the locomotive is to be used for transporting agricultural and other
produce or material from place to place a box or receptacle is provided, as shewn
in Figure 1, which box or receptacle is carried at the rear upon the tie bar e¹
and extends over the top of the main wheel or roller and is carried at the front
on a bar n¹. In order to permit of tipping this recepacle to discharge its contents
it is provided on the underside with a pawl n² adapted when dropped to engage
with the surface of the main wheel in such a manner that by backing the
engine slightly the desired tipping of the receptacle will be effected. To prevent
the said receptacle from tipping too far back under the action of gravity a bar ³
is pivoted to the front of the said receptacle and adapted to slide over the bar n¹,
in such a manner that when the receptacle is tipped to its extreme position
hook on the end of the said bar will engage with the bar a¹ (as indicated by
the dotted lines in Figure 1) and arrest the motion.
a
When the engine is to be adapted for use for steam cultivating purposes the
main axle d is made to project beyond the side arms or brackets e, e as shewn in
Figures 2 and 3, and these projecting portions have loosely mounted upon them
the winding drums o, o¹. For the purpose of transmitting the motion of the
main axle to the said winding drums, an arm is mounted upon the said axle
in connection with each drum, each of the said arms carrying a pawl p¹ which
can be placed in position to engage with one or other of a series of lugs p² upon
the inner periphery of the drum, as indicated by the dotted lines in Figure 1, or
in position to allow the drum to rotate independently of the motion of the arm p,
whereby if, say, the pawl of the drum o is in position to engage with one of
the lugs and the pawl of the drum is out of engagement with the said lugs,

page_text: the drum o will, as the engine is driven, coil up the rope attached to it whilst the
other drum will be rotated by the unwinding of the slack rope. The pawls p¹, p¹
may be moved to engage them with and disengage them from the lugs 22 by any
suitable means, for instance, by means of a lever rod p³ as shewn in Figure 1.
To check the too rapid rotation of the drums when the slack rope is being unwound
therefrom each arm p has arranged in connection with it a spring brake
which
is forced by a spring q, into contact with a suitable surface on the inner periphery
of the drum, as shewn in Figures 1 and 3. When the pawl pl is in contact with
one of the lugs 22 so that the drum rotates with the arm p obviously there will
be no movement between the brake q and the drum. When, however, either
drum is being rotated under the pull of the slack rope the drum will rotate
relatively with the brake the latter moving in the opposite direction to that
in which the drum is rotating.
It will be obvious that when the winding drums are being driven the pin m
will be drawn out of the wheel so that no movement will be imparted to the
main wheel c as the wheel rotates with the axle.
In addition to providing the winding drums as hereinbefore described I also
mount upon the axle of the front wheels b a beam or frame r carrying pulleys,
over which the ropes are passed, the said beam being connected with the axle by
links s, s which permit of the said beam partaking of a lateral movement to pre-
vent the rope from "piling" upon the drums when being wound thereon.
In cases where it is advantageous to carry a large supply of water I prefer to
make the main or travelling wheel e in the form of a water tank for carrying a
reserve supply of water in addition to that arranged in the tank g below the
foot plate of the tender. In order that this reserve may be drawn off as desired
I arrange in one side of the tank near the boss a discharge pipe t, provided
with a stop cock 1, which rotates with the wheel and around the axle but fixed
to the framing of the engine I arrange a circular channel u, Figure 3, into which
the discharge pipe t extends and which communicates by a pipe with the tank y
in such a manner that the water as it flows out of the wheel c will enter the said
channel and gravitate thence into the tank g. So long as the water level is
above the top of the said discharge pipe, when the latter is in its lowest position,
water will flow through the same by gravity during the whole or a part of the
revolution of the wheel according to the level of the water in the tank. To
provide, however, for raising the water when below the level of the said pipe, I
arrange a kind of scoop or chamber which has an opening, for instance, as
at near the inner periphery of the wheel and into which the pipe t opens,
whereby, during each revolution of the wheel, the said chamber when at its lowest
position will be more or less filled with water, which, as the wheel rotates, will be
lifted and as the position of the chamber becomes reversed will gravitate through
the pipe into the channel u. A special pipe w normally closed by a cap or
plug is arranged on the tank, to which pipe a water lifter can be connected
for filling or emptying the tank when required.
Although I have described this part of my invention as applied to a road
locomotive, it is to be understood that the arrangement of a reserve water tank
and the means for removing the water therefrom can be applied to the wheels of
motor carriages and other vehicles on which it is desired to carry a relatively large
supply of water.
When my locomotive is to be used as a road roller I advantageously arrange in
connection with the water tank a water sprayer or distributer which is
adapted to deliver water from the tank g upon the road immediately in front of
the roller wheel, a cock al which can be operated by a rod a² from the tender of
the locomotive is provided for controlling the delivery of the water through the
said distributer.
In Figure 2 of the drawings the main wheel c is represented as provided with
cross bars with spaces between them for affording a good grip upon the ground.
In order to adapt this wheel as a roller I insert filling strips between the said

page_text: spaces in order to produce a smooth surface, or, if desired, I may provide loose
cylindrical segments which may be bolted on to the cylinder so as to cover the
surface of the wheel. Instead of using bars as hereinbefore described a plain
roller may be shod with wooden bars or battens, as indicated in Figures 4 and 5,
which battens may, if desired, be faced with india-rubber or have india-rubber
strips upon them in order to afford a firm grip upon the ground and reduce
vibration and jolting when travelling.
Although in the foregoing description I have referred to the roller behind the
fire box as being the main travelling wheel it is to be understood that in some
cases the axle may be removed and travelling wheels of suitable diameter placed
upon the main axle in place of the winding drums hereinbefore described.
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:-
1. A road roller or locomotive having a roller wheel mounted immediately
behind the fire box the opening through which the fuel is supplied to the fire
box and the tender being on one side of the boiler, substantially as described.
2. The combination with a road locomotive of a receptacle for transporting
produce or material, the said receptacle being arranged to pivot upon the framing
of the locomotive and provided with a pawl or the like for engagement with the
travelling wheel in order to tip the said receptacle by backing the engine sub-
stantially as described.
3. In a road locomotive provided with a roller travelling wheel immediately
behind the boiler, of an axle upon which the said roller or wheel is mounted
extending beyond the framing and carrying rope winding drums and provided
with pawl or other mechanism whereby the motion of the said axle may be
transitted to either of the said drums whilst the other drum may be allowed to
run loosely, substantially as described.
4. In a road locomotive a hollow wheel forming a water tank in combination
with a discharge pipe, a channel concentric with the said wheel into which the
discharge pipe delivers, the said wheel being provided with a scoop or chamber
for delivering the water when the level of the latter is below the level of the
discharge pipe, substantially as described.
5. The combination with the fore-carriage of a road locomotive adapted for
steam ploughing of a swinging beam or frame, carrying guide pulleys, sub-
stantially as, and for the purpose, described.
6. The improved locomotive provided with a roller wheel, tip receptacle and
winding drums constructed and arranged substantially as herein before described
and illustrated in the accompanying drawings.
