I, GEORGE SIDDELL of Roewood, Crabtree, Pitsmoor, Sheffield in the County of
York, Forge Manager do hereby declare the nature of my said invention for
AN IMPROVED MECHANICAL APPLIANCE FOR WORKING OR OPERATING ON, LARGE
FORGINGS IN IRON OR STEEL to be as follows:-
"
"
This Invention relates to the construction and application of an improved and
more simple and effective mechanical appliance or means, for working or operating
on large forgings in iron or steel, being such forgings as are usually made under a
hydraulic forging press or machine.
My improved appliance consists of a horizontal bar or bars made of suitable
metal and fitted with suitable pulleys and hooks, which bar or bars can be placed
or fitted on either side of the crosshead of the forging press, or through the "pellet"
or key way.
.
Clips or grips or ratchets are conveniently arranged so as to fix on or hold the
ingot or.forging and hooked on the ratchet or clip or grip; and in operating, when
the press lifts up or is raised, the ingot or forging will be turned as much as
required at every stroke or operation of the press.
•
The crank bar of the press in connection with the wheel and endless chain
thereof will raise the forging from the anvil at the same time that the clip or grip
or the ratchet is turning the forging, the ratchet being suitably fixed for turning
the crane wheel over which the endless chain passes.
The ratchet has a chain attached to the crane girder which will travel along a
horizontal bar suitably fixed for the purpose and will turn over the ingot or forging
in the furnace.

on Large Forgings in Iron or Steel.
I GEORGE SIDDELL of Roewood, Crabtree, Pitsmoor Sheffield in the County of
York Forge Manager do hereby declare the nature of my said invention for
AN IMPROVED
FORGINGS IN IRON OR STEEL," and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement in
writing, and on reference being had to the accompanying sheets of drawings, that
is to say -
MECHANICAL APPLIANCE FOR WORKING OR OPERATING ON LARGE-
This Invention relates to the construction adaptation and application of an
improved more simple and effective mechanical appliance or means for working.or
operating on large forgings in iron or steel, which forgings are such as are usually
made under a hydraulic forging press or machine or a steam hammer; and in order
that the carrying out of my invention in practice may be fully understood,
I have illustrated it on the accompanying two sheets of explanatory drawings, and
have marked the same with letters of reference corresponding with those in the
following description thereof, that is to say:-
Figure 1, on Sheet 1, is an end elevation or view, and Figure 2, is a front or
face view of one arrangement of my mechanical appliance for working large
forgings.
A, is the hydraulic forging press or machine. G, is the endless chain: which is
attached to the crank bar of the press, and which passes over the wheel W, and
under the ingot or forging or mandril F, which is being operated upon' by the
press A.
The wheel W, is held in position by means of the crane block hook b, and
shackle or bridle a; the crane with the horizontal bar and carriage are not shown
on the drawings.
On or to the centre pin of the wheel W, is attached a double or single lever L,
having pawls or ratchets R, (one only being shown on the drawings) working on
pins. The ratchets engage in teeth provided for them on the wheel W.-When
the endless chain G, is slack the ratchet lever L, falls or is forced in towards the
centre so as to crank or bend the chain to any required extent, and when the
weight of the forging comes on the chain it tends to straighten it, and the pressure
on the end of the lever L, is transferred to the pawl or ratchet R, and thence to
the teeth of the wheel, which will cause it to rotate on its axis to the desired
extent. An eye or other convenient appliance E, is attached to the end of the
ratchet lever L, in order to work the ratchet and rotate or turn the wheel
independently of the endless chain G.
Figure 3, on Sheet 1, shows the appliance arranged and applied in another
manner; the centre pin of the wheel is connected with a cranked bar K, or by.
other convenient means to the pellet or crosshead of the press, whereby the
wheel W, and endless chain G, are simultaneously raised when the pellet is lifted.
The chain when Black is cranked or bent as before mentioned, and when the pellet
rises the ingot or forging rises with it, and the consequent straightening of the
chain forces round the wheel W, by means of the ratchet lever (not shown in this

page_text: Figure) and so turns over the forging at the same time that it rises from the anvil;
or it can be made to turn the forging by means of the eye provided at the end of
the ratchet lever L, and thus this arrangement of the appliance can be made either
automatic or self-acting, or it can be worked by steam or other power inde-
pendently of the appliances shown at Figures 1, 6, and 7; for the working of the
forging under the steam hammer.
This appliance can likewise be used to turn over the ingot or forging when in
the furnace, and it is operated by the crane as an automatic appliance, or when
suspended the forging can be turned by working the ratchet lever L, by any
convenient means, such as by steam or other power.
In the combination and arrangement of the appliance, as shown at Figures 4
and 5 on Sheet 2, a horizontal bar B, is provided and fixed on or through the cross-
head or pellet of the press, this bar carries one or more bridles c, and rollers d,
with one or more hooks or shackles H attached to them. An adjustable clip or
ratchet grip X, is put on to the ingot or forging or mandril F, and an eye e, on the
end of the screw or lever f, is attached to the hook or shackle H. When the pellet
or crosshead of the press rises, the clips or ratchet grips X, engage with or grip the
ingot or forging or mandril, and the leverage so obtained will turn over the forging,
and when the pellet descends the appliance will release itself and will slip round to
obtain a fresh hold for the next lift.
The wheels and endless chains shown at Figures 6, and 7, on Sheet 2, which are
similar to those described as shown at Figure 3, on Sheet 1, can also be used in
combination with the appliances represented at Figures 4, and 5, on Sheet 2, and
the forging will be lifted up from the anvil and turned over to the required extent,
at the same time that the press rises.
The appliance as shown at Figures 1, and 2, on Sheet 1, can also be used in
combination; in fact each arrangement of appliance can be used either separately
or combined, for the purposes of lifting slinging or turning over the ingot or
forging when in the furnace, under the press or hammer, or when being otherwise
operated on.
The ratchet appliance has a chain attached to the crane girder, which will travel
along a horizontal bar provided and fixed for that purpose, or with the crane
carriage and will turn over the ingot or forging in the furnace.
. Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be and can be performed, I here
declare that I do not limit myself to the precise details of my invention as herein-
before specified and as illustrated on the accompanying drawings, because equivalent
modifications or variations can be made in such details, and quite consistent with
the principles or characteristic features of my invention; and in conclusion I declare
that what I claim is
The general construction, adaptation or application, and the combination and
use of the several parts, in the whole, constituting improved more simple and
efficient appliances or means for working or operating on iron or steel forgings,
substantially as herein before set forth, and as illustrated on the accompanying
drawings.
