I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.
do hereby declare the nature of this invention to be as follows:-
The object of the invention is to design a machine in which iron, steel or other
metal may be upset and simultaneously formed into any desired shape without in any
way injuring the metal; and it consists essentially of a machine having a slowly-
moving ram arranged to upset metal by direct and steady pressure, reciprocating
rollers acting on the metal and driven at a high rate of speed being operated in
connection with the slowly-moving ram for the purpose of keeping the metal straight
during the operation of upsetting, and at the same time forming the said metal into
any desired shape.

Apparatus therefor.
A communication from WILLIAM Ross, of the Village of Lachine, in the County of
Hochelaga, in the Province of Quebec, Canada, Machinist, and HARRY DEAN
BUSH, of 3 Lorne Crescent, in the City of Montreal, in the County of Hochelaga,
in the Province of Quebec, Manufacturer.
1. ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.L.M.E.
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 :-
The object of the invention is to design a machine in which iron, steel or other
metal may be upset and simultaneously formed into any desired shape without in any
way injuring the metal; and it consists essentially, of a machine having a slowly
moving ram arranged to upset metal by direct and steady pressure, reciprocating
rollers acting on the metal and driven at a high rate of speed, being operated in
connection with the slowly moving ram for the purpose of keeping the metal straight
during the operation of upsetting and at the same time form the said metal into any
desired shape, the whole being constructed and operated substantially as hereinafter
more particularly explained.
Fig. 1 is a perspective view of this improved upsetting machine, with a portion of
one of the guide-bars broken away. Fig. 2 is a cross section of the special centre
rollers and side dies used in upsetting and rolling eye-bar heads. Fig. 3 is a plan of
the same rollers.
Before referring to the specific parts of this machine I may say that I do not
claim anything new in an upsetting machine having a slowly moving ram for the
purpose of upsetting the metal, as my correspondents are aware that such machines
are now made; but in all machines of this kind with which my correspondents
are familiar the bar of metal being upset is distorted and if of iron the fibres are
bent and separated by the spreading force caused by the compressing force of
the ram.
In the adoption of quickly moving rollers arranged to operate over the portion
of the metal being upset I am enabled to keep the fibres of an iron bar straight to
keep a steel bar from folding back on itself, and to increase the strength of either
metal by additional "working" which this rolling gives it.
In the drawings -
A is a heavy bed-plate, on which all the parts of this machine are carried.
B is a driving pulley carried on a shaft suitably journalled in boxes carried in the
bed-plate A. This driving-pulley is connected to any suitable motor, and is geared as
indicated, or in any other suitable manner, to the shafts C and D so that the said
shafts shali revolve with the driving-pulley B.

page_text: A hydraulic cylinder E is securely bolted to the bed-plate A and is preferably
connected to the head-block F by the rods G which act as guide-rods for the truck H.
The lower rollers 1 are suitably journalled in the lower portion of the truck H and
the upper rollers J are journalled in suitable boxes K held in guides formed on
the upper portion of the truck H. Each of the boxes K is suitably connected
to a spindle I which spindles are all connected together as indicated in Fig. 1,
by gearing operated by a hand-wheel M so that the rollers J may be readily adjusted
vertically nearer to or farther from the rollers 1 to suit the thickness of the "metal
being acted upon.
The hydraulic cylinder E is connected to any suitable hydraulic pump the con-
struction of which is not necessary to be described in this specification. This pump is
operated by the shaft C which is connected to the crank-shaft of the pump by the
pitman Nas shown.
The truck H derives a reciprocating motion from the shaft D to which it is
connected as indicated, by the connecting rods 0.
The cross-head P connected to the plunger of the hydraulic cylinder E is connected
to the end dye Q. It follows therefore, that when the machine is in operation the
truck H has a quick reciprocating motion, while simultaneously the cross-head P with
its end die Qis slowly moved longitudinally toward the head-block F. The rollers I
and J will of course be made any shape which it is desired and intended to form the
metal to be upset, and are located at such a point that they will travel backward and
forward over the surface of the metal where it is being upset.
In operation this machine acts as follows ;-
The bar R which in the drawings represents the piece of metal to be upset, is first
heated at the point to be acted upon, and is then inserted between the side dies S, and
is locked in positions by the cams T. The machine is put into operation and the end
die Q is brought slowly against the end of the bar R and is pressed against it with a
steady powerful force sufficient to upset or enlarge the cross section of the bar, which
naturally has a tendency to increase in thickness, but which is kept to a uniform
thickness by the rapid reciprocating motion of the rollers I J; or if the metal is to be
formed into any other desired shape than that shown, the forms of the rollers and dies
are changed and by their action will shape the end of the bar R into the desired form.
The reciprocating action of the rollers on the bar R is very beneficial in working the
metal while it is being upset, as it retains the fibrous character of the metal, if of iron,
and works out all blow-holes, small cracks &c. in steel due to imperfect rolling in the
process of its original manufacture.
The combined upsetting and rolling machine is shown with the upsetting plunger
driven by hydraulic power and the roller truck driven, as described, from the driving
pulley B. The upsetting plunger might also be driven by steam or other power and
the truck by steam or other power direct. 1 therefore do not confine the invention to
any particular motor power.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my foreign
correspondents, I declare that what I claim'is:
1. In an upsetting machine a slowly moving die for longitudinally compressing the
bar being upset combined with quickly moving rollers for vertically compressing said
bar and suitable side dies by which said bar is laterally formed or shaped substantially
as described:
2. An end die arranged to act against the end of the bar being upset and means for
giving said die a slow but powerful longitudinal movement combined with rollers
arranged to act on the portion of the bar being upset means for giving said rollers a
quick reciprocating movement suitable side dies for forming or shaping the metal
forced into them by the end die and rollers and clamping devices constructed to grip
the bar being acted on and sustain the quick reciprocating motion of the rollers sub-
stantially as and for the purpose specified.

page_text: 3. In an upsetting machine a slowly moving die constructed to longitudinally
compress the bar being acted upon combined with quickly moving rollers arranged
to simultaneously laterally compress the bar and to pass over the surface of that
portion of the bar being upset substantially as and for the purpose specified.
4. An end die arranged to act against the end of the bar being upset and means for
giving said die a slow but powerful longitudinal movement combined with rollers
arranged to act on the portion of the bar being upset means for giving said rollers
a quick reciprocating movement and clamping devices constructed to grip the bar
being acted upon and to resist the longitudinal movement of the end die and sustain
the quick reciprocating motion of the rollers substantially as and for the purpose,
specified.
5. The guide-rods G the cross head P supported on said guide-rods and the
end die actuated by said cross-head combined with the truck H supported on said
guide-rods the rollers I J and mears for giving said truck a reciprocating movement
to cause the said rollers to act on a portion of the bar being upset substantially as and
for the purpose specified.
6. The within described machine for upsetting iron, steel or other metals, con-
structed substantially as herein shown and specified.
Dated this 6th day of April 1889.
