PROVISIONAL SPECIFICATION.
Improvements in Travelling Cranes.
I, ALFRED ROWE BELLAMY, of Algoa Lodge, Adswood Lane, Stockport, in
the County of Chester, Engineer, do hereby declare the nature of this invention
to be as follows
:-
My invention relates to improvements in driving and giving motion to the various
parts of travelling cranes and the improvements consist chiefly in the employment
of gas or hydrocarbon vapour as the source of motive power.
In carrying out my invention I mount upon the base plate of the crane a suitable
gas or other similar motor engine with a water tank to maintain a circulation of
water round the power cylinder, and also to counterpoise to some extent the jib of
the crane. The gas bag and a branch gas supply pipe may be supported by the
water tank and the explosive fluid mixture is supplied by any suitable flexible pipe
connections to the supply pipe. The exhaust pipe from the power cylinder is
preferably connected to a tank or reservoir supported by the truck which carries
the crane and engine.
On the crankshaft of the engine is secured a spur wheel in gear with a wheel on
a second shaft on which are secured three clutches or disengaging gears, the first
for driving the rope or chain barrel for hoisting, the second giving motion to a
chain wheel and chain for travelling the crane on its rails; and the third for
driving a vertical shaft on which is a spur pinion gearing into a circular rack for
swinging or turning the jib of the crane as required, all these movements being
under control of an operative on the platform of the crane.

COMPLETE SPECIFICATION.
Improvements in Travelling Cranes.
I, ALFRED ROWE BELLAMY, of Algoa Lodge, Adswood Lane, Stockport, in
the County of Chester, 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 relates to improvements in driving and giving motion to the various
parts of travelling cranes and the improvements consist chiefly in the employment
of gas or hydrocarbon vapour as the source of motive power.
In carrying out my invention I mount upon the base plate of the crane a suitable
gas or other similar motor engine with a water tank to maintain a circulation of
water round the power cylinder and also to counterpoise to some extent the jib of
the crane. The gas bag and a branch gas supply pipe may be supported by the
water tank and the explosive fluid mixture is supplied by any suitable flexible pipe
connections to the supply pipe. The exhaust pipe from the power cylinder is
preferably connected to a tank or reservoir supported by the truck which carries
the crane and engine.
On the crankshaft of the engine is secured a spur wheel in gear with a wheel on
a second shaft on which are secured three clutches or disengaging gears, the first
for driving the rope or chain barrel for hoisting, the second giving motion to a

-driving a vertical shaft on which is a spur pinion gearing into a circular rack for
swinging or turning the jib of the crane as required, all these movements being
under control of an operative on the platform of the crane.
And in order that my invention may be fully understood and readily carried into
-effect I will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig. 1 is a side elevation, and Fig. 2 a plan view, partly in section, of a combined
travelling crane and gas engine for operating the same.
Fig. 3 is a sectional end elevation showing the main gearing.
In the drawings, a represents the body of a travelling crane mounted on
wheels a' the axles of which are connected by chains a²; on the base plate or
platform a of the crane is mounted a gas or other similar motor b with a water
tank c to maintain a circulation of water round the power cylinder b¹ and also to
counterpoise to some extent the jib a' of the crane. To the side of the tank c is
secured a gas bag d connected by a pipe e to the motor; the explosive fluid
mixture is supplied by any suitable flexible pipe connections e¹ to the gas bag d;
the exhaust pipe f from the power cylinder is preferably connected to an exhaust
box or chamber g supported on the frame of the crane. On the crank shaft h of
the engine is secured a spur wheel i in gear with a wheel ; on a second shaft k on
which are fitted clutches or disengaging gears for driving the rope or chain barrel
travelling the crane and swinging the jib of the crane which are effected in the
following manner :-
A friction wheel secured upon the shaft k gives motion to the rope barrel by
means of a friction wheel secured upon the axle of the barrel l; one end of this
.axle is mounted in an eccentric and a lever, not shown, is employed to move the
friction wheel into contact with the wheel when it is desired to give motion to
:the barrel and raise a load. To traverse the crane along its rails a pair of bevel
wheels n are fitted upon feather keys in the shaft k; a handle n¹ is employed to
'move either of these wheels into gear with a bevel wheel o secured upon a shaft o¹
carried in a bearing o' on the crane carriage; to the other end of this shaft o¹ is
keyed a bevel wheel of which gears into a wheel p' keyed on the axle pou which
are secured chain wheels p³ for driving the chains a³ and travelling the crane in
either direction.
On the shaft k is a second pair of bevel wheels 9 fitted on feather keys; either
of these wheels can be moved by a handle q¹ into gear with a wheel, keyed upon
a shaft carried by bearings in the platform a*; on the shaft is keyed a pinion,³
in gear with a circular racks; this racks is made in one piece with or secured to
the frame a and the platform at on which the crane and engine are secured is
:supported to swing or turn in either direction according to the direction of
movement given to the pinion.
Any convenient form of friction clutch for driving and reversing the parts of
the crane other than those described may be employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A travelling crane combined with a gas or similar motor engine and arranged
substantially as and for the purposes described and as illustrated in the
accompanying drawings.
