PROVISIONAL SPECIFICATION.
Improved Means for Upsetting as also Welding Together the Edges of
Metal Plates.
I, JOHANN SCHEIBNER, Engineer, of No. 11, Malapaner Strasse, Oppeln,
Germany, do hereby declare the nature of my said invention to be as follows.-
The present invention relates to machinery for upsetting the edges of metal
plates and for welding the edges of such plates together
According to my invention the edge of a metal plate is upset or thickened
in the following manner
-
The plate is placed on a suitable table having a pressure bar adapted to slide
vertically thereon and to be clamped fast down on to the plate at a distance from
the end of the same, and across its whole width, so as to leave the required length
fiee which is to be upset
About
Above this free lying end of the plate a vertically adjustable pressure head 18
provided, which may be adjusted to a height above the end of the said plate,
corresponding to the thickness to which the plate end is to be upset
parallel to the end of the plate and extending along the same, a guideway 18
provided in the stout frame of the machine opposite to the edge of the plate
A roll 18 then pulled or pushed by means of a suitable bar in which it is revolubly
mounted between the end of the plate and the guideways previously mentioned,
so that it will upset the said plate end forcing the metal displaced into the
space formed in front of the clamped pressure bar and beneath the adjustable
pressure bar.
The roll is interchangeably mounted on its pusher or pull-bar and when the
first roll has been caused to act on the end of the plate, the adjustable bar is
again adjusted a little higher and a larger roll is then drawn or pushed through
the path between the guideway and the edge of the plate and thus the upsetting
operation may be gradually completed.
The adjustable pressure bar which limits the thickness of the part upset is
advantageously adjusted by means of horizontally moveable wedges mounted
in the machine frame and moved by means of right and left hand screws to
and from each other according to requirement, but any suitable means of adjust-
ment may be employed
The holder bar, which as stated should tightly hold the plate near its end and
across its whole width, may be pressed down on the plate by means of hydraulic
or other pressure
In order to diminish the friction caused by forcing the upsetting roll through
between its guideway and the edge of the plate, two or more laterally arranged
rolls are provided on its spindle, which are advantageously of smaller diameter
and run along the guide ways opposite the end of the plate, the said guideways
being advantageously provided with a groove in which the main upsetting
roll runs freely, its opposite circumferential part pressing on the edge of the
plate, whilst the pressure against the guideway is borne by the smaller rolls
previously mentioned and disposed at either side of the upsetting roll proper.

page_text: The mechanism for welding together the ends of a plate to form for instance
a tube or for other purposes consists of the following parts:-
Two rolls are advantageously employed one beneath and the other above the
abutting or overlapping plate ends Each roll has its guideway one mounted
below the plate and the other above and supported in suitable frame Each
guideway 18 provided with laterally extending arms adapted to rest on the plate,
the arms of the lower guideway pressing upwardly against the plate and those
of the upper guideway pressing down on the plate and on the lower arms, along
a length of the plate about equal to the guideway length. If the edges of the
plate are being welded together to form a tube the upper and lower rolls are
shaped to conform to the diameter of the tube and the meeting surfaces of the
laterally extending holder aims may he provided with interchangeable blocks
having surfaces also corresponding to the diameter of the tube The rolls are
mounted substantially in the same manner as the roll previously described in
connection with the upsetting machinery and are both pushed or pulled through
their guideways and along the plate edges simultaneously in order to effect the
welding together of the ends The plate ends are advantageously heated by
means of a water gas burner which is passed along with the rolls.

Improved Means for Upsetting as also Welding Together the Edges of
Metal Plates.
I, JOHANN SCHEIBNER, Engineer, of 11, Malapaner Strasse, Oppeln,
Germany, do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement
-
The present invention relates to machinery for upsetting as also for welding
together the edges of metal plates and comprises the details of construction
herein after set forth and particularly pointed out in the claims
In order to render the present specification easily intelligible reference is
had to the accompanying drawing in which similar letters of reference denote
similar parts throughout the several views. -
Figs 1 to 3 show machinery for upsetting the edge of a plate and Figs 4
and 5 shown a modified form for welding together the edges of a tube or the
like
Fig 1 is a vertical section on the line of Fig. 2, Fig 2 a horizontal
section on line y of Fig. 1 and Fig. 3 a cross section on line of Fig. 1
Fig sa part cross sectional elevation of the machinery for welding together
the edges of plates and Fig. 5 a longitudinal section through the same
Refering to Figs 1 to 3 - In the stout frame of the machine a pressure
head is mounted to shde vertically up and down in suitable dove tail grooves
(Fig 2) being pressed down on to the metal being worked by means of a
hydraulic cylinder e in the usual manner Below this pressure head is mounted
a table on which the plate to be worked is laid The upper part of the pressure
plate or block is provided with a strong houzontally extending flange f and as
will be seen from Figure below this flange is houzontally mounted to turn a

The device operates in the following manner -The edge of the plate a to
be worked having been properly heated the plate 18 laid on the tablet with its
edge extending beyond the right hand edge of the pressure head d to the extent
to which it is to be upset The said head is then pressed tightly down on to
the plate across the whole width of the same by means of the hydraulic pressure
cylinder e The moveable plate is now adjusted to a height above the plate
corresponding to the height of the upset part of the plate, which will be
attained by the first passage or passages of the 1oll over the said nd
wedges being adjusted by means of the screw spindle n and hand wheels
keep the said plate in proper position
The tail is now pulled 01 pushed
along the edge of the plate which will be upset thereby and when the plate has
attained the thickness allowed by the adjustable plate h, the latter may be
adjusted to a higher position by moving the wedges g apart and the plate edge
again heated and further worked and so on until the desned thickness of the
upset part is attained in that a roll b of greater thickness or diameter 18 sub-
stituted for the first roll
