I GEORGE SIDDELL of Roewood, Crabtree, Pitsmoor, Sheffield in the County of
York Steel Forge Manager do hereby declare the nature of this invention to be as
follows:-
This Invention relates to and consists in the application and employment in
combination of single and double wheels for the purpose of facilitating the rotation of
ingots or large forgings of iron or steel while being operated on under the hydraulic
forging press or steam hammer.
The single wheels I employ have teeth or clutches made on the outside, or on the
sides, of the flanges of the wheels, if required, for the purpose of turning or driving
the carrying wheel with the endless chain carrying the ingot or forging.
Or these wheels can be made and used plain, and when so made I bolt them
together, or I key or cast them fast on the pin or shaft on which they are put.
Or I have and use what I term a double wheel having two grooves or channels
made in the periphery of it, round which the endloss chain or chains of the rotating
apparatus will pass; this double wheel is made in one casting and I run it loose on
the shaft or pin on which it is put.
•
The single wheel or one side of the double wheel is intended to be worked from
the ordinary overhead crane by a chain or an equivalent therefor, and will thereby be
caused to rotate the carrying wheel which carries the ingot or forging and the endless
chain of the rotating apparatus, and so effect the turning of the ingot or forging.
The use of my improved rotating appliance will prevent the ingot or forging from '
over-running or falling back.
My single wheel can be used, if required, in connection with my appliance for
working or operating on large forgings for which Letters Patent were granted to me
dated the 20th day of May 1885 No. 6205.

I GEORGE SIDDELL of Roewood Crabtree Pitsmoor Sheffield in the County of
York Forge Manager 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 relates to mechanical appliances whereby ingots or large forgings 5
may be turned or rotated with ease and facility while under the action of a steam
hammer or hydraulic forging press and consists in the employment of certain
constructions and combinations of wheels and chains as hereinafter described with
reference-to-the-accompanying drawings.
According to one inode of carrying out my Invention as illustrated by Figure 1 1
I provide a compound wheel A that is to say a wheel having two grooves a b in the
periphery, one of which grooves a being for the reception of an endless chain B by
which the ingot or forging is supported and the other groove b for the reception of a
chain C in connection with an overhead travelling crane by which the compound
wheel is rotated when required. This compound wheel A may be mounted to turn 1
freely on the shaft or spindle D fixed in a suitable frame or between shackles E
carried by a pulley block suspended by a chain from the overhead crane by which the
frame and wheel together with the ingot or casting may be raised and lowered as
required. The groove b in which the chain C for rotating the wheel works may have
recesses therein, corresponding to the links of the chain so as to prevent the chain 2
from slipping. Instead of the wheel being free to turn on the shaft or spindle D it
may be fixed to the said spindle and the latter be free to turn in suitable bearings in
the frame or shackles E. When it is required to move the forging from place to
place, for example, to and from the heating furnace and the forging press, the chain (
may be slackened to prevent the ingot being rotated.
Instead of a double grooved wheel as herein before described I may employ two
separate wheels A A¹ as shewn in Figure 2 mounted on one and the same shaft or
axle D and capable of being coupled together when required to impart motion to the
ingot. Round the wheel A¹ passes the chain C from the overhead crane whilst the
other wheel A carries the chain B which supports the ingot or forging. These
wheels are provided with clutch blocks F as shown in Figure 3 or other suitable
devices such for example as ratchets and pawls fixed to the wheels for coupling them
together when desired, for the purpose of imparting rotation to the ingot or forging
and for uncoupling them to prevent the forging rotating when being moved from
place to place.

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. An improved mechanical appliance for rotating ingots or large forgings of iron
or steel while under the action of an hydraulic forging press or steam hammer
consisting of a wheel having two grooves in one of which works the chain supporting
the ingot being operated on, and round the other groove passes a chain from an over-
head crane by which rotation is imparted to the wheel substantially as and for the
purpose hereinbefore described with reference to Figure 1 of the accompanying
drawings.
2. In apparatus for imparting rotation to ingots or large forgings of iron or stee!
while under the action of an hydraulic forging press or steam hammer, two grooved
pulleys mounted side by side on one and the same shaft or spindle and provided
with clutch blocks or equivalent means for coupling and uncoupling the two wheels
substantially as and for the purpose herein before described with reference to Figures 2
and 3 of the accompanying drawings.
