Ingots of Iron or Steel in the Process of Heating and Forging.
I. WILLIAM DANIEL ALLEN of the Bessemer Steel Works, Sheffield, in the County
of York, Steel Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to means having for object to obtain better control than
by the means heretofore usually employed over large ingots of iron and steel during
the heating and forging process, and to enable them to be moved about, turned over
and otherwise manipulated more rapidly and with less manual labour.
For these purposes according to my invention in lieu of the ordinary over-bead
crane usually employed there is substituted a hydraulic crane similar in general
design to the ordinary centre ladle crane used in the casting pits of Bessemer Steel
converting houses, but having the head and top framing arranged and constructed for
supporting, and provided with means and appliances for working, a strong and
powerful arm or porter bar to the fore end of which the ingot can be secured and
thereby carried as it were at arm's length, shifted, turned over, or otherwise moved
through the agency of the said porter bar, the necessary power and the desired
motions for effecting the required movements being imparted to the porter bar by
hydraulic, steam, or other power.

I, WILLIAM DANIEL ALLEN of the Bessemer Steel Works, Sheffield, in the
County of York, Steel Manufacturer 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 has reference to means having for object to obtain better control,
than by the means heretofore usually employed, over large ingots of iron and steel
during the heating and forging process, and to enable them to be moved about, turned
over, and otherwise manipulated more rapidly and with less manual labour.
For these purposes according to my invention in lieu of the ordinary over-head
crane usually employed there is substituted a hydraulic crane similar in general
design to the ordinary centre ladle crane used in the casting pits of Bessemer Steel
converting houses, but having the head and top framing arranged and constructed for
supporting, and provided with means and appliances for working, a strong and powerful
arm or porter bar to the fore end of which the ingot can be secured and thereby
carried as it were at arm's length, shifted, turned over, or otherwise moved through
the agency of the said porter bar, the necessary power and the desired motions for
effecting the required movements being imparted to the porter bar by hydraulic, steam
or other power.
The accompanying drawings will show clearly the nature of my invention and a
means of carrying out the same.
Fig. 1 is a sectional elevation of my hydraulic forging crane, and
Fig. 2 is a plan, partly in section (one steam cylinder being removed).
Fig. 3 is an end elevation, partly in section and
Fig. 4 a cross section in linea a of Fig. 2, the worm wheel T being in elevation.
The floor line of the building or forge is shewn by the letter A, and B is the
foundation into which the lifting or main cylinder is firmly secured; D is the ram,
and the head of the ram, to which the side plates F, F and other portions of the
framing are attached. G is the strong arm or porter bar, which it is advantageous to
make in the hollow cylindrical form, in order to get the greater strength with the
least weight, and also to allow of the long end of a forging passing down the centre.
The front end of the arm or porter bar is supported in the trunion shaped piece H
in which it is free to move endwise backwards and forwards and also to turn round.
1 is a crosshead or trunion for supporting the back end of the porter bar and in

page_text: which it is free to rotate only, but end wise, the porter bar and crosshead travel
backwards and forwards together; the crosshead is supported by the anti-friction
rollers K K which run between strips rivetted to the side plates F. The crosshead is
held in its place on the end of the porter bar by the wheel Q on the one side and the
collar A on the other. Z is a counterbalance weight.
The ram D together with the crane and all the machinery and appliances carried by
it may be turned round in the cylinder C, and this circular horizontal motion may be
given to the same by means of two small steam cylinders R one of which is seen
in Fig. 2 the other comes over the hydraulic cylinder J that is shewn in section.-
The cylinders R are secured to the side frames, they work at right angles, are fitted
with reversible gear, and drive the shaft and worm S; this worm works into the
worm wheel T which is fastened upon the vertical shaft U, the bottom end whereof is
round and rests upon the crane in a socket, so that the crane is free to turn round
whilst the shaft is stationary. The upper portion of the shaft above the wheel is square
and passes through a square eye in the block V in which it can slide freely up and
down as the crane is raised and lowered. The square eye piece V may be fixed to the
roof of the building where convenient, or be otherwise securely held in its proper
position, and prevented from turning round, thereby also preventing turning of the
shaft U and worm wheel T, which then constitute a fulcrum round which the worm S
when put in motion gyrates, carrying the crane with it.
Racking in and out or backward and forward motion may be given to the porter
bar by means of the two hydraulic cylinders J J the pistons of which are secured to
the side arms of the crosshead I.
Rotatory motion may be given to the porter bar by two small steam cylinders L, L
attached to the back end of the framing, working at right angles, and fitted with
reversing gear these cylinders drive the shaft and worm M and the worm works into
and drives the worm wheel N, which is fixed upon the end of the square shaft O; this
shaft extends horizontally along the inside of the framing to the socket B²; a pinion P
with square eye (and having an extended boss with a collar on one side of it) slides
freely upon this square shaft O, and gears into the wheel Q, which is securely fixed on
the back end of the porter bar; the pinion P that slides along the square shaft is made
to travel backwards and forwards simultaneously with the porter bar (and is kept in
gear with the wheel Q) by means of the above mentioned extended boss and collar;
the boss resting in a recess or journal formed in the crosshead I where it is retained
by a cap.
Water under pressure may be conveyed to the cylinders J, J through a hole formed
down the centre shaft U, an inlet pipe being provided that enters the said hole
through a stuffing box at the top end of the shaft; the outlet at the bottom of the
shaft will also require a small stuffing box for the connecting pipe to the cylinders.
Steam may be conveyed to the cylinders L and R by an elastic steam coil pipe.
A moveable socket or holder W of such size as to suit the work in hand may be
used for holding the ingot, and the moveable holder may be attached to the end of the
porter bar by bolts or otherwise.
The ingot X may be cast with a shank Y and secured in the socket or holder by
wedges.
As will be evident hydraulic cranes with arms or porter bars adapted to carry ingots
and with mechanism for operating the same in such a manner as to effect the necessary
shifting turning over or otherwise moving of such ingots through the agency of the
said porter bars, according to my invention, as above set forth can be constructed in
forms varying more or less in detail from the arrangement I have illustrated.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The use for carrying turning and otherwise manipulating ingots of iron or steel
in the process of heating and forging, of a hydraulic crane constructed with an arm or

page_text: porter bar adapted to carry an ingot and with mechanism for operating the same in
such a manner as to effect the necessary shifting, turning over, or otherwise moving
of the ingot through the agency of the said arm or porter bar.
2. My improved crane for carrying, turning and otherwise manipulating ingots
of iron or steel in the process of heating and forging substantially as set forth and
described.
Dated this 25th day of August 1888.
