COMPLETE SPECIFICATION.
Apparatus for Turning Heavy Forgings and the like.
1, EDWARD REYNOLDS, of the River Don Works, Sheffield, Civil Engineer,
lo 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 apparatus which may be suspended from a crane or
traveller, for the purpose of turning heavy masses of metal while they are heated or
forged by hammering or pressing, similar apparatus being applicable for turning
other heavy masses such as ladles or converters. The chief object of my invention
is the arrangement of the motor gear in two parts, the lower part having on it the.
chain for carrying and turning the forging or other object, and the upper part
mounted on the hook of the crane pullies in such a manner that the act of hooking
on the lower part effects engagement of the two parts of the motor gear.
crane or traveller carrying the upper part of the gear can be moved about so as to
engage with and work sets of the lower gear at different places. Fig. 1 of the
accompanying drawings is a front view and Fig. 2 is a side view of apparatus
according to my invention.
The
A is the lower pulley block of the crane or traveller and B is the hook, which is
swivelled to A as usual but by a tubular swivel through which passes a worm
spindle C.
The hook B also has in its upper back part a central slot within which is
accommodated a worm wheel D gearing with the worm C.
On the upper end of the worm spindle C is fixed a toothed wheel E gearing with
a pinion on a vertical spindle F which is worked by any suitable motor on the
crane or traveller, with any known connection allowing it to move up or down with
the pulley block A, this connection being of a telescopic or chain kind or it may be
jointed as described in my Provisional Specification No. 1675 of 1891.
Various connections of this kind are known and form no part of my invention,
which relates only to the gearing worked by the spindle F, whatever be the means
of giving motion to F. On the ends of the shaft of the worm wheel D are fixed
pinions G, which, when the apparatus is in use, gear with wheels H. These
wheels H are always held by links I in gear with wheels J fixed on the axis of
the barrel K over which passes the chain L. The two wheels H revolve freely on
a strong cross pin M which can be introduced obliquely or withdrawn from the
hook B. When it is introduced, the wheels H are brought into gear with the
pinions G, and then, on the spindle F being caused to revolve turning the worm C,
the worm wheel D and pinions G are caused to revolve driving the wheels H which
in their turn drive the wheels J and the barrel K. The chain L being thus caused
to travel, its lower bight holding the forging or other body to be turned causes it
to turn. On withdrawing the cross pin M from the hook B, the crane or traveller
with its pulley block and the parts carried by it, namely the spindle and its
pinion, the wheel E, worm spindle C, worm wheel D and pinions G, can all be
moved away, and may be engaged with another set of the wheels H and J, barrel K
and chain L.
Having thus described the nature of this invention, and in what manner the same
is to be performed, I claim :-
In apparatus for turning heavy forgings and the like, arranging the gearing
and with

set forth.
