New or Improved Fire-engine Operated by Means of a Petroleum-
motor.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of Middles
sex, Patent Agent, do hereby declare the nature of this invention, às communi-
both in
cated to me by Leon Porteu, of Rennes, and Theodore Cambier, of Lille,
France, to be as follows:-
The steam fire engine has already been employed with good results, and the
object of the present invention is to produce a fire engine actuated by a petroleum
motor.
The motor is furnished with four cylinders arranged in pairs, these cylinders
being horizontal and four-cycle cylinders, capable of yielding 20 h.p.
The motion of this motor is transmitted from its shaft, which is horizontal and
arranged in the longitudinal direction of the vehicle, to an intermediate shaft
parallel to the axles, by means of bevel gearing.
This intermediate shaft may be connected, as desired; either with the shaft
that carries two sprocket wheels which, by means of two chains, effect the rota-
tion of the rear road wheels, or with the shaft, which by means of two cranks
operates the two pistons of a fire engine with two barrels.
1.
The transmission of the motion of the intermediate shaft to that of the rear
road wheels, is effected by means of pulley belts; two rates of speed are obtained
by means of two crossed pulley belts connecting pullies; having different connee-
tions these rates of speed .are transmitted from the loose pulley to the fixed
pulley by means of a shifting fork. The backward movement is effected by a
straight belt which is put into engagement by means of a coupling screw.
The point where the fire has broken out having been reached, the belts are
disengaged, and by means of conical engaging and disengaging coupling and
toothed gearing, the crank shaft of the double barrel engine is operated, and. the
engine immediately throws out very powerful streams of water.
The vehicle in its entirety comprises seats or benches. for the fire-men, tool-
chests and the means for conveying the hose pipes.
All the driving gear, management of the brake axle, brakes, change of direc-.
tion, etc., are all under the control of the driver. sitting in the front of the
vehicle.

The coupling or uncoupling of the pump, on the contrary, can only be made
from below, by the tire-men who move about on the ground and place the pump
in battery.

New or Improved Fire-engine Operated by Means of a Petroleum-
motor.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of Middle-
sex, Patent Agent, do hereby declare the nature of this invention and in what
manner the same is to be performed, as communicated to me by Leon Porteu,
of Rennes, and Theodore Cambier, of Lille, both in France, to be particularly
described and ascertained in and by the following statement:-
The steam fire engine has already been employed with good results, and the
object of the present invention is to produce a fire engine actuated by a petroleum
motor.
In the accompanying drawings Fig. 1 is a longitudinal elevation and Fig. 2
a plan of the improved fire engine.
The vehicle is driven from the axle of the rear road wheels. In the front part
of the vehicle are two seats sand S, each of which is capable of holding three
persons if necessary. The driver sits on the seat S which is higher than the
other s, and has within his reach there the apparatus for guiding and controlling
the vehicle.
The hind part of the vehicle is occupied by the motor which, if desired, can
actuate the road wheels R or put in action the fire engine placed in the centre
of the vehicle. Quite at the rear end is a broad foot-board N, by means of
which, with the assistance of the hand-rail n, and subject to a relaxation of the
speed, it is possible to mount the vehicle while the same is in motion.
The motor M is furnished with four cylinders arranged in pairs opposite to
one another. The rods of the four pistons are arranged in two couples on two
crank shafts at 180 degrees, which transmit motion to the shaft A carrying the
dy-wheel V. By means of a bevel gearing E, rotary motion is transmitted from
the shaft A to an intermediate transverse shaft a on which are mounted :-
1. A conical friction clutch K, whereby the double chamber fire pump P
can be put in action, through the medium of a spur gear e which operates the
crank shaft p;
2. The driving pullies for actuating the shaft, furnished with differential gear
and carrying the spur wheels c, which by means of a chain and tooth wheel C,
drive the hind wheel R.
The shaft a carries three pulleys B, G, and D. B and D correspond with the
pairs of pulleys 6 b₁ and d d mounted on the shaft c; b and d being fixed pulleys
and bloose pulleys.
Each of the pairs of pulleys 6 b₁, d d¹ is connected with the pulley B and the
pulley D, by means of crossed belts, which are carried from 6 to 6 and from d
to d¹ by means of a shifting fork.
The pulley G is connected with the pulley g by a straight belt which effects
the backward movement. This belt is loose on the pulleys G and and is
tightened thereon by means of an intermediate pulley (not shown in the drawings)
lying in the plane of the belt and connected to a lever operated by the driver.
The vehicle can thus be driven forward at two rates of speed (one rate of speed
per hour by means of the pulleys D) and d and another rate of speed per hour by
means of the pulleys B and 6) and backward by means of the pulleys G and
g.
The pulleys and belts are completely separated from the pump P by means
of a flat-iron screen T, so that they are beyond the reach of any leakage or
discharge of water and thus no inopportune lengthening of the belts can occur.
It is for the purpose of entirely avoiding any inconvenience of this kind

page_text: arising from the pump that the transmission thereof is effected by means of
gearing.
The different rates of speed are regulated by means of a hand-wheel and a
lever . The brakes are worked by the pedal and the vehicle is steered by
means of the hand wheel f which acts on the pivots of the divided front axle
which is attached to the steering wheels F.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what
I claim is
1. The general arrangement above described, of an automotor fire engine,
characterised by the optional transmission of the power from a single motor,
either to the driving wheels or to the double action pumps substantially as
described.
2. In an automotor fire engine actuated by a petroleum motor the arrangement
of the seats, foot-board, &c., whereby persons may be carried conveniently and
without fatigue and are enabled to mount the vehicle easily whilst the same is
in motion substantially as described and illustrated.
3. A new or improved fire engine operated by means of a petroleum motor
all combined and arranged to operate substantially as and for the purpose herein
described and illustrated in the accompanying drawings.
