page_text: I, GEORGE SAXON, of Openshaw Engineering Works, Manchester, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improvement in forging and welding machines
such as are or may be employed for uniting two bars of iron or steel of either flat,
square, angle, round, or other section, or for forging flange couplings, bossing
flat bars, ends of shafts and other like uses. The object of my invention is to effect
a substantial improvement in the present machine used for the above purposes by
substituting a true horizontal movement of the gripping vices and the material
to be operated upon instead of as heretofore a curved movement caused by the
radial action of the ends of levers working from a fixed centre at the end.
According to this invention I construct a strong metallic frame, preferably of
cast iron, with two parallel sides or cheeks, one of the said sides or cheeks is cast
with the bed of the machine which has a recess formed on the opposite side thereof
for the reception of a corresponding side or cheek that is bolted to the bed so that
a space is left between the sides of the frame. I form horizontal grooves or slides
in the upper portions and near each end of each cheek in which the ends of short
transverse shafts, or slide blocks fixed thereon are fitted so as to slide therein;
horizontal links that are each formed with an eye to work eccentrically on a cam
or eccentric shaft on their inner ends are placed longitudinally in the space
between the sides of the machine, side by side through both of which and through
the centre of eacli of the sides of the machine a cam, or eccentric shaft, is fitted
transversely. The outer ends of the said horizontal links are each supported by
the short transverse sliding shafts, or slide blocks, herein before mentioned so
that the said bars may be moved in a longitudinal direction and are thus connected
to serrated gripping vices that move simultaneously when operated by a handle
I fit an anvil in
or lever fixed upon the cam or eccentric shaft for that purpose.
the centre of the machine over or above the aforesaid cam or eccentric shaft.
In order to unite the ends of two shafts of steel or iron the said ends are heated
and the shafts are each placed between the serrated gripping vices herein before
named, with their heated ends near to each other where they are firmly retained.
Each of the heated ends of the shafts so fixed are then forced against each other
by turning by means of a handle or lever the transverse cam or eccentric shaft
and the eccentrically acting links herein before mentioned, and the smiths or
strikers at the same time hammer the joint on the anvil; when sufficiently welded
by these means, the shaft is removed and placed under the steam hammer which
completes the operation either at one heat or by a second heat, if required.
Flange bosses and the like are in the same manner produced or welded on shafts
hama

I, GEORGE SAXON, of Openshaw Engineering Works, Manchester; in the County
of Lancaster, Engineer 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:―
This invention relates to an improvement in forging and welding machines
such as are or may be employed for uniting the ends of two bars of iron or steel
of either Hat, square, angular, round, or other section, or for forging flange coup-
lings, bossing flat bars, ends of shafts and other like uses.
In the accompanying drawing, Fig. 1 is a side view, Fig. 2 is a plan, and Fig. 3
an end view of a machine constructed according to my invention, Fig. is an
alternative form of grip or vice. In these views similar letters refer to similar
parts..
According to this invention I construct a strong metallic frame of cast iron with
two parallel sides or cheeks as a a¹; one of the said sides or cheeks is cast with
the bed of the machine which has a recess a² on the opposite side thereof for the
reception of a corresponding side or cheek a¹ that is bolted to the bed so that a
space is left between the sides of the frame; I form horizontal grooves or guides bb₁
in the upper portions and near the ends of each cheek in which the ends of short
transverse shafts c c¹ slide or are fitted in blocks which may slide therein; hori-
zontal links d d' are placed longitudinally side by side but in reverse positions in
the space between the sides of the machine, each of the inner ends of said links
being formed with an eye to work eccentrically on a cam or eccentric fitted on a
shaft e placed transversely and centrally and having a bearing in each side of the
machine; a hand lever as f is fitted to one end of the said transverse shaft by
which to actuate the aforesaid horizontal links. The outer ends of the links d d¹
are each connected to a gripper or vice as which may be adjustable as shown in
Fig. 2. An eccentric gripper g is fitted on a stud g¹ on the extended base of and
opposite cach of the aforesaid grippers and is operated by a handle k: the face
of each of said grippers is preferably serrated. I fit an anvil m in the centre of
the machine over or above the aforesaid cam or eccentric shaft. The machine is
constructed so as to be removable; it can be securely fastened down on planking
by coach screws or on a suitable metal plate by bolts, and thereby economize
space, as it may be placed out of the way when not required.
In order to unite the ends of two shafts of steel or iron, the grippers or vices
and
y are set to suit the size of the bars to be welded, extra holes 9* and * being
provided for the purposes of adjustment.
Care is taken that the butt ends of the pieces to be welded come opposite each
other when tried in the machine the ends of said pieces are then brought to a
welding heat and simultaneously placed between the aforesaid grippers, the parts
to be joined resting on the anvil block m, the two pieces are then immediately
gripped by the vices by turning the handles inwards towards the centre of the
machine. The lever f is pulled down which thereby causes the grippers at either

page_text: end to approach nearer the centre and force the heated ends of the bars into each
other.
During the time the pressure exists the outside of the weld is closed by ham-
mering. To close the bottom of the weld the bar is turned round after lifting
the lever and opening the vices; the bar may then be swaged on the anvil or
under the steam hammer; for the purpose of forging a collar on the end of a bar
a square block is fitted into one of the vices, the end of the bar is heated and com-
pressed against the block until the iron is increased in size sufficiently for the
collar.
j
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
i
1. A forging and welding machine that is constructed with sides or cheeks in
which horizontal grooves as bb¹ are provided for guiding and supporting grippers
or vices that are moved horizontally in a longitudinal direction towards the
centre of the machine by a cam or eccentric centrally placed that is operated by
a lever as f in the manner and for the purpose substantially as described.
2. In a forging and welding machine the combination of a frame consisting
of two sides or cheeks with horizontal grooves therein, transverse shafts or bars
whose ends are formed to slide in said grooves, grippers or vices connected to and
guided by the aforesaid transverse shafts and moved horizontally nearer to or
further from the centre by horizontal links operated by a cam or eccentric all
substantially as and for the purpose herein before described.
