COMPLETE SPECIFICATION.
Machine for Jumping, Bordering, and Flanging Pipes.
We EDUARD NEUMEISTER, Engineer of Wiesenstrasse 4, Hörde, and
RICHARD SOBOTKA of Westendstrasse 19, Magdeburg-Sudenburg, both in the
Empire of Germany, 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 a machine provided for jumping, bordering and Hanging
pipes and is represented by the annexed three sheets of drawings, in which Fig. 1
shows a front view; Fig. 2 a plan view of the machine; Fig. 3 is a side view
whilst Figs. 4 to are cross sections on the lines a¹-b', c'-', e respectively.
The machine consists of a frame a upon which the support b is movably fixed.
This support b is provided with a clutch surface-plate c and serves to clamp the
ends of the pipes to be bordered or flanged. The clutch plate c is not directly
attached to the support b but to a plane disc c firmly fixed to said support whilst
plate c is pivotally connected with the by-plate c by a vertical hinge joint a
allowing a turning of plate c for a right angle with relation to the horizontal axis
of the discs if the pin has been lifted connecting the two discs e c¹ by
corresponding eyes. The surface plate e is provided with three radially movable
clutches d which can be approached to the centre of the disc in known inanner as
the sliding clutches d are fastened like nuts on screw spindles ending near the
middle in bevelled gears gearing all together with a conical wheel fixed on the
shaft . This shaft is provided with a screw wheel and gears with a worm,
whose shaft can be operated by turning the hand wheel s. To the support bis
given a sliding movement in the direction of the bed a by a leading screw y.
Another support e is also movably put upon the frame a which with its annular
head encloses a collar floosely put into it. This collar is a part of the disc f
into the face of which are radially put in corresponding slits the sliding pieces i;
a screw i gearing with a toothed wheel, whose side face gears with the sliding
pieces, allows a contemporary approaching of the pieces to the middle off.
The pieces are provided with pins supporting the cylinders, the cross section.
of which corresponds to the intended form of the flange or jumping.
The support g is in its middle formed as an hydraulic pressure cylinder having a
piston whose top is enlarged to a plane disc h¹ upon which the cylinders k are
movably fixed in the same manner as is the case with the disc fand the cylinders i
respectively. The cylinders correspond with their cross-section to the inside of the
pipe to be flanged or jumped. The circumference of is provided with teeth and
gears with a pinion I actuated by the loose and fixed pulleys t, t'.
The working of the machine is as follows-
The one end of the pipe v is red-heated in a convenient furnace and the surface
plate e turned aside for receiving the (cold) end of the pipe; hereupon the disc is
turned in the position of the drawing and the clutches pressed against the
circumference of the pipe by the above mentioned arrangement. It must be
declared that for bringing in the pipe, the support 6 must be unscrewed by the
leading screw y in due measure for bringing the hot end of the pipe between the
rollers i. The support b is now made to advance corresponding to the length of
the pipe. Hereupon the hydraulic pressure cylinder g is engaged and in the same
time the gear is made to turn by the pulley t in consequence of which the piston h
will make in the same time a progressive and, by the effect of the gear 1, a turning
movement so that the rollers k will be introduced into the pipe and will rotate in

page_text: its inside. The disc is provided with pins o locking into corresponding holes of
disc fso that the latter will also be turned. In this way the right form is given
the flange or jumping. When the work is done the pressure water is, by a
reversible valve, conducted behind the by-piston g¹ and the piston h will be
withdrawn.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A machine for jumping, bordering and flanging pipe ends having rollers arranged
around the middle of a rotary disc, the axes of which run parallel to that of said
disc and are fixed to supports movably fixed in radial slits of the disc, which rollers
have a cross section corresponding to the surface of the flange etc. to be formed,
said machine having a second rotary ring provided with rollers corresponding to
the inside of the pipe to be flanged, this ring being the top plate of an hydraulic
press, substantially as set forth.
