PROVISIONAL SPECIFICATION.
New and Improved Methods of Transferring Pig-iron from the
Pig-bed.
WILLIAM JONATHAN BEST, Engineer of 19, Rogers Street, Blackhill, County
Durham, & EDWARD JENNINGS JENNINGS, Engineer of 13, Victoria Street West-
minster London, S.W., do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to facilitate the removal to trucks or otherwise of the
iron pigs or the like from the pig bed or its equivalent and for this purpose we
arrange a framework or rail bed carrying a bridge or its equivalent after the manner
of that used in a travelling crane. This spans the pig bed & is fitted with a revolving
dredger capable of engaging with and raising the pigs from the bed, for this purpose
having, as it were skeleton buckets or arms so that no sand is raised with the pig.
This dredger or its equivalent having a traversing motion upon the bridge and the
bridge being capable of movement upon the rail bed it is obvious any portion of the
pig bed can be operated upon by the dredger or its equivalent. The pigs upon being
raised to the bridge & becoming disengaged from the dredger or its equivalent, rest
upon rollers suitably shaped & having a rotary motion imparted to them so that the
pigs are made to traverse the bridge & after passing, if desirable, under a cogging
roller or other breaking appliances are deposited into trucks or otherwise dealt with.
The bridge instead of having rollers may obviously be fitted with other equivalent
transferring arrangements as for instance, an endless chain or the like forming a
travelling bed to receive the pigs.
The whole apparatus may be worked by the agency of stean water electricity or
other motive power or where desirable hand power may be utilized; the general
arrangement enabling the clearing of the pig bed to be much facilitated.

New and Improved Methods of Transferring Pig-iron from the
Pig-bed.
WILLIAM JONATHAN BEST Engineer, Rogers Street, Blackhill County Durham
EDWARD JENNINGS JENNINGS Engineer, 13 Victoria Street, London, S.W., 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:
The object of this invention is to facilitate the removal to trucks or otherwise of the
iron pigs or the like from the pig bed or its equivalent and the better to explain the
meaning reference is made to the accompanying drawings.
For the purpose we arrange a framework or rail bed, A on the drawings, carrying
a bridge B or its equivalent after the manner of that used on a travelling crane. This
spans the pig bed C, and is fitted with a revolving dredger D capable of engaging
with and raising the pigs E from the bed, for this purpose having as it were skeleton
buckets or arms F so that no sand is raised with the pig.
This dredger or its equivalent having a traversing motion upon the bridge and the
bridge being capable of movement upon the rail bed it is obvious any portion of the
pig bed can be operated upon by the dredger or its equivalent.
The pigs upon being raised to the bridge and becoming disengaged from the
dredger or its equivalent rest upon rollers & suitably shaped and having a rotary
D

passing if desirable under a cogging roller or other breaking appliance are deposited
into trucks or otherwise dealt with. The bridge instead of having rollers may
obviously be fitted with other equivalent transferring arrangements as for instance an
endless chain or the like forming a travelling bed to receive the pigs.
The whole apparatus may be worked by the agency of steam, water, electricity or
other motive power or where desirable hand power may be utilized, the general
arrangement enabling the clearing of the bed to be much facilitated.
In the illustration a steam engine after the manner of that on a crane is mounted
upon the frame carrying the dredger and it will be readily understood without
elaborate drawings that it can be set to work the dredger by the band H, to cause the
bridge to travel by the band I working a wheel (which wheel travels along a square
axle joining the bridge wheels and accompanying the dredger in its movements upon
the bridge) and it will further be readily seen that the band J working the bevil
wheels K & K produces a relative movement of the dredger upon the bridge. By
clutches under the control of the driver any of these can be thrown into or out of
gear in the usual way. It is obvious that the invention is not confined to mounting
the boiler and engine on the frame and the exact arrangement shown, for instance an
electrical motor only might work the whole thing the current being produced at a
distance therefrom, or any other convenient method of power transmission might be
used and the bridge might work at right angles to its present position the dredger
being similarly altered as regards the bridge so as always to grip the pigs in the same
manner.
Having now particularly described and ascertained the nature of the said invention
we declare that what we claim is.
Firstly The arrangement or combination of the parts of a machine as and for the
purpose indicated substantially as described and illustrated.
Secondly The use in connection with a pig bed or its equivalent of a machine
having rotating prongs or claws capable of engaging with and raising the various
pigs or castings and depositing the same upon a self delivering way or guide or in
such position as may be considered desirable substantially as described.
Thirdly The combination in connection with a "pig bed" of a travelling or
adjustable bridge and a dredger capable of motion thereon enabling the whole or
nearly the whole of the bed or beds to be operated upon substantially as described.
Fourthly The combination in connection with a dredger capable of operating upon
the pig bed or beds of a delivering way or guide embodying a series of rotating rollers
or an endless band or chain substantially as described.
Fifthly The combination with the above with a cogging roller or equivalent pig
breaking device as and for the purpose set forth.
