I, PETER BAGOT, of 15, Brinkburn Street, Sunderland, in the County of Durham,
Team Owner, do hereby declare the nature of this invention to be as follows:-
My invention relates to motor driven road vehicles, and has for its object to adapt
any ordinary wagon, lorry or other road vehicle to receive a motor for driving purposes
in a cheap and convenient manner, thus obviating the necessity of a special wagon
when horses are dispensed with.
To this end, my invention consists essentially in removing the shafts of the wagon
or other vehicle and prolonging the fore carriage, such as by means of angle irons,
which I deck over to form a platform adapted to receive a motor of any suitable known
construction. I support the front end of the prolonged fore carriage by one or two
wheels which serve to guide the vehicle (one being sufficient in most cases); suitable
means such as a chain, lever or toothed gearing being provided to control the guide
wheel or guide wheels from a hand wheel or lever located near the driver. On the
naves of the two fore wheels of the vehicle (preferably on the outside) I mount
sprocket wheels to which the power from the motor is transmitted by an endless
chain at each side. By this means, the ordinary wheels of the vehicle are utilised
for driving the vehicle, which is most advantageous, as the load being directly on
said wheels renders them specially adapted for driving purposes.
The motor employed may be a steam or oil engine, an electric motor or a
compressed air engine, but in most cases I prefer to employ a compound steam engine
which I mount together with its boiler on the prolonged fore carriage as aforesaid,
the water tank being preferably placed below at the rear of the vehicle. In this case,
the water tank can be utilised for exhaust steam when travelling through towns or in
other places where the steam would prove objectionable.
In order to simplify and render more reliable the steering of the vehicle by
preventing skidding in turning, I form the tyre of the guide wheel or guide wheels
of T-section with the web or fin on the outside or tread. This will be found of great
utility in vehicles of this class as the web takes firmly into the ground whilst the
flanges prevent sinking in soft ground.
The ordinary hand brake will in most cases be found effective, but I may, where
necessary or desirable, affix to the vehicle a steam brake. In such case I prefer to
adapt the one steam valve for both brake and motor, so that on the motor being
stopped by the steam being shut off, the brake will be simultaneously applied.
In carrying out the invention, I prefer to form separately the motor carrying.
prolongation for the fore. carriage, and provide it temporarily with a pair of rear
wheels to support it at the rear. By this arrangement, the motor may be taken
from one vehicle to another, and after it has been bolted and secured rigidly to the
fore carriage, the temporary wheels may be taken off. If desired the temporary
wheels may be driven by endless chains from the motor when moving the latter from
one vehicle to another.
By my invention there is afforded the great advantage of a ready adaptation of
existing vehicles to self propulsion, and particularly the ready means of detaching

page_text: and attaching the motor from and to any one of several vehicles, the
one carriage extension with motor sufficing for any number of wagons or
vehicles.
As a modification of my invention I may employ one or more traction wheels
encased with wood or having roughing ribs to grip the ground instead of utilising
the vehicle wheels for driving purposes. These wheels (preferably two) will be
attached underneath the wagon or vehicle in the centre and immediately in front
of the rear vehicle wheels by an iron frame with an ordinary plate spring above.
They will thus also assist in carrying the load, and will leave the ordinary vehicle
wheels free for their intended purpose of carrying the load.
With this arrangement
I place the motor on the floor of the wagon or on an extension of the body
of the vehicle and transmit the power by an endless chains to sprocket wheels
mounted on the axle of the traction wheels, the chains being guided when necessary
by suitably placed guide wheels. The steering of the vehicle may be effected by
means of the guide wheel as aforesaid, or by a suitable gearing adapted to work the
ordinary front wheels or fore-carriage.
The great advantage of this modification consists in its ease of attachment to
existing wagons whereby every portion of the wagon is left to perform its ordinary
work as hitherto.
A semi-circular platform is preferably erected at the front end of the wagon or
vehicle over the guiding wheel to provide standing room for the stoker, steersman,
driver, or the like.

I, PETER BAGOT, of 15, Brinkburn Street, Sunderland, in the County of Durham,
Team Owner, 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 motor driven road vehicles and has for its object the
arrangement of any ordinary wagon, lorry, or other road vehicle so as to receive a
motor for driving purposes in a cheap and convenient manner, thus obviating the
necessity of a special wagon when horses are dispensed with.
My invention is best described by aid of the accompanying drawings, in which,
Figure 1 is an elevation of a lorry with my invention attached thereto;
Figure 2, a similar view of a modification thereof.
In taking any ordinary lorry or wagon, I remove its shafts and prolong the fore
carriage. This is shown in Figure 1, in which A is the floor of a lorry, B the fore
carriage. This fore carriage is extended very considerably in length by means, in
this particular instance, of two angle irons D, one at each side supporting a flooring.
This flooring or angle iron is again supported at its front end by a fork E carrying a
wheel F. This fork by means of arms Hand a chain I attached to each of these two
arms and passing round a sprocket wheel J can be turned to point in any direction
by means of hand-wheel K. Any other well known gearing can be used for moving
this front steering wheel and a two wheeled bogie or other carriage swivelling on
a pivot can be used instead of a single wheel. Between the fore wheels L, preferably

page_text: inside the wheels, I mount sprocket wheels M to which the power from the motor is
transferred by an endless chain N at each side of it, in some instances a single chain
is used. By this means the ordinary wheels of the vehicle are utilised for driving it,
a most advantageous arrangement, as the load. being directly on said wheels renders
them specially adapted for driving purposes. The motor P can be a steam engine,
an oil engine, or even an electric or compressed air motor. For most cases I prefer
to employ a compound steam engine as shown which I mount together with its boiler
on the prolonged fore carriages BD, the water tank being preferably placed below at
the rear of the vehicle or any other part. The water tank can be utilized for
condensing the exhaust steam when travelling through the towns or other places
where steam would prove objectionable. In order to simplify and render more simple
the steering of the vehicle by preventing skidding in turning, I form the tyre of the
guide wheel F or the wheels of its equivalent carriage of T-section with a web or fin
on the outside or tread. This will be found of great utility in vehicles of this class,
as the web takes firmly into the ground, while the flanges prevent sinking in soft
ground. This web stands about an inch from the flat surface of the wheel, but may
be more or less according to the nature of the ground traversed. For city use it can
be done away with altogether. The ordinary band-brake will in most cases be found
effective, but I may where necessary or desirable fix to the vehicle a steam brake.
In such case I prefer to adopt one steam valve for both brake and motor so that on
the motor being stopped by the steam being shut off the brake can be simultaneously
applied. Where however a gas or oil engine or an electric motor be applied other
arrangements can be adopted whereby the brake can be simultaneously applied with
the shutting off of the steam. In some cases I may have the motor platform
provided with temporary rear wheels so arranged that they can be slid under and
fixed to the ends of the angle irons when these latter are withdrawn from the fore
carriage of the lorry or other vehicle and thus the motor can be taken from one
vehicle to use with another. In other cases I may extend the body of the lorry or
other vehicle and place the engine on the extension. This idea is set forth in Fig. 2
in which A is the main platform and D¹ the fore carriage. This fore carriage can be
made to swivel in the ordinary manner by means of hand-wheel K connected by
gearing to the central pivot of the fore carriage, or hand-wheel K can be connected as
in Fig. 1 with arms H on the fork E of a fifth wheel F. In this case I prefer to
have two rails S, one attached to the body and the other to the platform D¹ so that
the one can slide on the other. In some instances I may drive from a subsidiary
wheel T behind, in which case the sprocket gearing set forth in the drawings could
be used, though in most cases the axle U would be lowered so that the cover of the
sprocket wheels thereon should not appear above the level of the platform. W is a
tank which can be put in any convenient position for supplying water to the engine.
The lock bolt X of the centre carriage is made hollow so as to allow the rod from
wheel K to pass through it. It will be seen from the above that by my invention is
afforded the great advantage of ready adaptation of existing vehicles to self propulsion
and particularly the ready means of detaching and attaching the motor from and to
any one of several vehicles, one carriage extension or platform D with motor sufficing
successively for several vehicles. The bearing wheels can be of any desirable kind
preferably with a slight rib as already described, but sometimes I may employ extra
wheels or drums T encased in wood and having roughing ribs to grip the ground
instead of utilizing the vehicle wheels for driving purposes. These wheels will be
attached underneath the wagon or the vehicle in the centre immediately in front of
the rear vehicle wheels by an iron frame with an ordinary plate spring above. They
will thus assist in carrying the load and will leave the two vehicle wheels free. The
great advantage of the modification shown in Fig. 2 having these subsidiary wheels
consists in its easy attachment to existing wagons whereby every original portion of
the wagon is left to perform its ordinary work and is assisted by the new mechanism.
A suitable platform space is provided round the engine and steering wheel for the
stokers, steersman or the like.

page_text: 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. The combination with an ordinary lorry wagon or other vehicle of a
continuation of the fore carriage carrying a motor and steering gear and easily
detachable therefroin and attachable thereto substantially as described.
2. The combination with lorrys and other heavy vehicles of a motor placed thereon
and an additional traction wheel or wheels on the centre line of the wagon geared to
the engine and carrying a large part of the load substantially as described.
3. The general arrangement of combination motor and lorry or other vehicles 1
substantially as herein described and.illustrated.
