I GLORGE SIDDELL of Roewood Crabtree Pitsmoor Sheffield in the County of York
Forge Manager do hereby declare the nature of this Invention to bo is follows
-
My Invention relates to that description of apparatus for turning ingots or heavy
forgings in which the ingot is supported and turned by meins of an endless chain
passing over a pulley to which a partial rotition is imparted to bring the required
parts of the ingot into position to be operated on and the object of niy Invention is
to provide an apparatus in which the necessary leverage is readily applied with
compactness and simplicity of parts resulting in economy of construction and ease
of manipulation
According to my Invention I mount in a framing (provided with means for
suspending it from a crane or the like) shaft or spindle upon which is carried the
wheel round which the chain for supporting the forging is pissed and on a separate
shaft or axle arranged parallel thereto I mount another wheel which receives motion
by means of a chain or rack from an overhead crane and on this axle is fixed a
pinion to gear into teeth provided on or affixed to the wheel round which the chun
for supporting the ingot passes or formed on the peripheries of the flanges of the
said wheel so that when the pinion is rotated by the chain or rich from the over
head crane rotation will be imparted to the ingot or forging through the teeth on
the other wheel and the chain cirried thereby To admit of different sized wheels
being employed (and consequently different leverage obtained) according to the size
of the ingot or forging I provide in the frame or shickles in which the shafts or
axles turn a number of holes or bearings arranged at suitable distances apart so that
the axles may be arranged nearer to or farther from each other to suit the different
sized wheels

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 that description of apparatus for turning ingots or heavy
forgings in which the ingot is supported and turned by means of an endless chain
passing over a pulley to which a partial rotation is imparted to buing the required
parts of the ingot into position to be operited on, and the object of my Invention is
to provide an apparitus in which the necessary lever ige is readily applied with
compactness and simplicity of parts resulting in economy of construction and case
of manipulation, and in which the levorage may be varied according to the size or
weight of the ingot
According to my invention I mount in framing (provided with means for
suspending it from a ciane or the like) shaft or spindle upon which is carried the
wheel 1ound which the chain for supporting the forging is passed, and on a separate
shaft or axle arranged parallel thereto, I mount another wheel which receives notion
by means of a chain passed round the sud wheel from an overhead crane, or by
means of a ratchet lever or levers worked from the crane or otherwise and gearing
with a rack formed on or attached to the wheel On the axle currying this wheel is
fixed a pinion or pinions or a worm or worms gering into teeth formed on or affixed
to the wheel round which the chain for supporting the ingot passes, so that when
the wheel is rotated by the chun or the ratchet lever or lovers and rack from the
overhead crane, rotation will be imparted by the gearing to the other wheel and
through the chain carried thereby to the ingot or forging
To enable the leverage
to be varied according to the size of the ingot or forging, I provide in the frame
or shackles in which the shafts or axles of the wheels turn a number of holes or
bearings arranged at suitable distances apart so that the said axles may be arranged
nearer to or farther from each other to suit different sized wheels according to leverage
required
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures
Figures 1 and 2 are elevations at right angles to each other of an apparatus
constructed according to my invention

page_text: A is a framing or shackle suspended by chains and pulley block A¹ from an
overhead crane not shown in the drawings In this frame are two shafts or spindles B
and C arranged parallel to each other the lower shift or spindle B carrying
wheel D round which passes the clann E by which the ingot F is supported and
turned On the flanges of the wheel D are formed spur teeth G or if desired instead
of forming the teeth on the flanges of the wheel separate spur wheels may be
attached to opposite sides of the wheel or to the shaft B upon which the wheel is
mounted so as to rotate with the wheel On the spindle or shaft C is mounted a
wheel H which receives motion by means of the chun I from the overhead crane
Attached to this wheel H or to the shaft C on which it is mounted are two pinions K
which gear with the teeth G on the flanges of the wheel D so that when the wheel H
is rotated by means of the chains I from the overhead crane rotary motion will be
Instead
imparted through the gearing K and G and endless chain E to the ingot F
of rotating the wheel H by the chain I direct, the said wheel may be turned by
means of a ratchet lever L shown by dotted lines in Figures 1 and 2 the said lever
carrying a pawl which may be arranged to gear with a rack a in the interior of
the wheel as shown, or with teeth formed on the flanges or on other suitable parts of
exterior of the wheel as desired, the rotary motion of the wheel H being transmitted
to the wheel D through the gearing K and G as before described I prefer to arrange
the wheel H inside the framing A as described and illustrated but I do not restrict
myself to this arrangement as the said wheel together with the ratchet lever may be
arranged outside the framing if desired as shown for example by dotted lines on the
left hand side of Figure 1 The direction of rotation of the ingot may be reversed
when required by reversing the direction of motion of the driving chun I when
acting directly on the wheel H, or when the ratchet lever motion is employed for
rotating the wheel H-I prefer to make the pawl with a double head as shewn in
Figure 2 so that by turning the level on the ale C the pawl may be caused to gear
with the rack on the diametrically opposite side of the wheel to reverse the direction
of its rotation, or if desired two iitchet levers may be employed operated from
diametric illy opposite sides of the wheel so that when it is required to reverse the
motion of the ingot the pawl on the lever which had been previously in use to
rotate the wheel in one direction, is thrown out of gear with the rack teeth on the
wheel, and the lever at the opposite side of the wheel brought into use by placing
the pawl carried by the said lever into gear with the rack teeth on the wheel to turn
it in the opposite direction
In order to regulate the leverige according to the size of the ingot to be operated
on I provide in the shackle or frame A a series of holes & to admit of various sizes
of wheels being placed in position in the frame to gear with the teeth G on the
flanges of the wheel D For this purpose the side or sides of the shackle or frame
may be removed to enable the shift Cand wheels H and K is to be detached bodily
from the apparatus and replaced by another shaft carrying different sized wheels,
the shaft of course being placed in one of the other purs of holes or bearings in
the frame A suited to the size of the wheels to be used or instead of removing the
sides of frame for this purpose the spindle C may be withdrawn from the wheels and
the frame, and then passed through other of the holes or bearings in the frame and
through the wheels to be substituted for those previously used The wheels may be
secured to the shaft or spindle C by any suitable means which will permit of their
being readily fixed and reinoved when required
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 In apparatus or means for turning or rotating ingots or large forgings the
combination with the wheel D carrying the endless chun by which the ingot is
supported, of the gearing G and K, and wheel H operated by means of the ratchet

drawings

panying drawings
