PROVISIONAL SPECIFICATION.
Improvements in Travelling and other Cranes.
JOSEPH PLATT, 9, St. Paul Street, Royton, in the County of Lancaster,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:
This invention consists of improvements in travelling and other cranes, and can
be worked either by hand or motive power, in my arrangement I accomplish the
three motions of hoisting, lowering, and transverse travelling, by one and the same
rope or chain, if worked from the floor, or by one and the same handle shaft if
worked overhead but preferably from the floor if by hand power.
In the accompanying drawings a Figs. 1, 2, and 3 is the ordinary pulley for
hoisting and lowering. To travel transversely I use a pinion & Figs. 1, 2 and 3
sliding on the shaft so that it can be put in or out of gear with the hoisting
wheel d this pinion can be put in or out of gear from below by means of a chain or
rope e, on the same shaft that pinion slides on is secured a wheel driving by
means of wheels "an auxiliary barrel y, these wheels may be mitres or of
such proportion that will give equal speed to the two barrels and h, when the
pinion is put in gear with hoisting wheel & the load then travels transversely in
one direction or the other according to the direction in which the hoisting pulley a
is worked, by this means I dispense with the ordinary gearing and rope pulley
required for transverse travelling, enabling one man to work all the four motions
of the crane in a simple and convenient way a clutch or other means of putting
the two shafts c and in gear may be used in place of a pinion, when the pinion b
slides out of gear with d it engages with a fixed, or stationary, wheel to prevent
rotation or a "break may be used for this purpose as shewn at j, when the
pinion slides in gear, the break ; is lifted simultaneously and when the pinion
slides out of gear, the break is lowered and prevents rotation of the shaft when
spur or bevel gear is used, if worm gear be used I dispense with break or fixed
wheel.
C
The longitudinal travelling is worked in the ordinary way by pulley k. The
auxiliary barrel g may be placed on and travel with the carriage as shewn at Fig. 4
Sheet 2 the wheels sliding in a grooved keyway in shaft i.
With my arrangement all the four motions can be worked from one end, and by
one man in a simple and efficient manner avoiding the danger and inconvenience of
overhead working and dispenses with the necessity of the operator crossing the
building or works where the crane is erected, and of coming in contact with any
machinery at the same time, this arrangement can be applied to jib or foundry
cranes, dispensing with the ordinary racking in and out gear.
Where the working across the room is not important, and a quick transverse or
cross travelling is desired with light loads, I place a rope or chain pulley on one of
the axles of the carriage.

COMPLETE SPECIFICATION.
Improvements in Travelling and other Cranes.
JOSEPH PLATT, 9, St. Paul Street, Royton, in the County of Lancaster,
Mechanical 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 :-
This invention consists of improvements in travelling and other cranes, and can

page_text: be worked either by hand or motive power, in my arrangement I accomplish the
three motions of hoisting, lowering, and transverse travelling by one and the same
rope or chain, if worked from the floor, or by one and the same handle shaft if
worked overhead, but preferably from the floor if by hand power.
In the drawings left with Provisional Specification a Figs. 1, 2, and 3 is the
ordinary pulley for hoisting and lowering, to travel transversely I use a pinion b
with
Figs. 1, 2, and 3 sliding on the shaft c, so that it can be put in or out of gear
the hoisting wheel & this pinion can be put in or out of gear from below by means
of a chain or rope e, on the same shaft that pinion slides on is secured a wheel
driving by means of wheels "an auxiliary barrel g these wheels may be mitres
or of such proportion as will give equal speed to the two barrels g and h, where the
pinion is put in gear with hoisting wheel d the load then travels transversely in
one direction or the other according to the direction in which the hoisting pulley a
is worked, by this means dispense with the ordinary gearing and rope pulley
required for transverse travelling, enabling one man to work all the four motions
of the crane in a simple and convenient way a clutch or other means of putting
the two shafts and in gear may be used in place of a pinion when the pinion
slides out gear with it engages with a fixed or stationary wheel to prevent
rotation or a break may be used for this purpose as shown at when the pinion
slides in gear the break is lifted simultaneously and when the pinion slides out of
gear the break is lowered and prevents rotation of the shaft when spur or bevel
gear is used, if worm gear be used dispense with break or fixed wheel. The
longitudinal travelling is worked in the ordinary way by pulley k. The auxiliary
barrel may be placed on and travel with the carriage as shewn at Fig. 4 Sheet 2
Provisional Specification the wheels sliding in a grooved keyway in shaft i.
With my arrangement all the four motions can be worked from one end and by one
man in a simple and efficient manner avoiding the danger and inconvenience of
overhead working aud dispenses with the necessity of the operator crossing the
building or works where the crane is erected and of coming in contact with any
machinery at the same time, this arrangement can be applied to jib or foundry
cranes dispensing with the ordinary racking in and out gear.
Where the working
across the room is not important and a quick transverse or cross travelling is desired
I place a rope or chain pulley on one of the axles of the carriage or gear the
same friction gear may be used in place of toothed gearing for light and quick
speeds where motive power is applied where the rope pulleys are required to be
parallel with walls of the building spur gear may be used in place of bevels.
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
An improvement for obtaining the transverse travelling by the same chain or
rope as the hoisting arrangement, and dispensing with the extra or ordinary motion
for transverse travelling, as hereinbefore set forth and more particularly described
in drawings and Specifications.
