An Improved Mangling Machine.
I, GEORG SOLBRIG, Engineer, of 10, Clobigauerstrasse, Merseburg, 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 an improved mangle which is made in three parts
capable of being locked together or taken asunder as desired. The mangle, which
may be used equally well by tall or short people, can be operated in confined
spaces, and, when the parts are taken asunder, can be easily transported from place
to place. Another advantage is that the lower part of the mangle can be adapted
for use as a pedestal or support for a suitably made table top or board.
And in order that the invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a front elevation.
Fig. 2 is a side elevation.
Fig. 3 is a half sectional side elevation, the section being taken on the line x, x,
Fig. 1.
Fig. 4 is a view, partly sectioned, showing part of the machine adapted to
support a table-top or board.
Referring to the drawings whereon the same reference numerals wherever
repeated indicate the same parts.
The machine consists of three separable parts A, B, C, which are locked together
in the manner hereinafter set forth.
The columns 1, 11, of the mangle carry the bearings 2,21, which are arranged
opposite each other within the removable middle part B, and in which the ends of
the axle of the working roller 3 revolve. This roller 3 is actuated, by means of a
spur wheel 6 and pinion 5, which latter is operated by means of the hand wheel 4.
On the opposite end of the axle of the working roller, from the hand wheel, is a
spur wheel 7 which gears with a spur wheel 8 on the axle of the pressure roller 9
so that the latter is caused to revolve simultaneously with the working roller.
The pressure roller and also the parts in connection therewith are removable along
with the upper part A of the machine. The ends of the axle of this roller 9
work in the bearings 10, 101, and it can, along with its bearings, be removed from
the columns when so desired. To retain the bearings securely in position studs 11
are provided which extend downwards into the middle part B of the columns. The
part A is also connected to the part B by means of the pressure adjusting
screws 12, 121.
Running between the pressure roller and the working roller is an endless
band 13. which passes over the revoluble guide rollers 15, and upon which the
materials to be mangled are placed. The guide rollers 15, which are carried by the
laterally projecting arms 14 of the frame, can be moved in or out laterally by
means of the screws 16 of the arms, so as to properly stretch the endless band or

page_text: for the purpose of enabling longer bands to be used if necessary with the object of
mangling larger articles easily and well.
The pressure roller is regulated by means of the hand wheel 4 whose teeth 41
engage with the pinion 18 of the shaft 17 which latter is provided, near each end,
with worms 19, 191, whose teeth mesh with the teeth of worm wheels 20, 20. The
bosses of these wheels 20 have hexagonal sockets into which are fitted hexagonal
nuts 21 screwed internally for the reception of the upper ends of the pressure
screws 12, 121, which latter are connected with the cylindrical foot 22. In the
hollow foot 22 of each column a pressure spring 23 is situated which is compressed
whenever the foot is raised up by the turning of the nuts 21 upon the ends of the
screws 12, 12, through the action of the worms and worm wheels, shaft 17, spur
wheel 18, and the hand wheel 4. By revolving the hand wheel 4 in the opposite
direction the foot 22 is forced against the plate 24 of the column with the result
that, as it cannot sink any further, the screwing action of the nuts 21 raises up
the roller 9. As the teeth of the toothed wheel are somewhat deeper than the pitch
of the screw of the nuts 21 and as the toothed wheel 18 itself is moved up simul-
taneously with the other parts, it becomes possible to lift out the pressure roller
owing to the fact that the toothed wheel 18 moves out of engagement with the
teeth 4 of the hand wheel 4 and the nuts 21 disengage themselves from the
pressure screws.
In order to make the part B removable the pillars 25 are recessed out at 26
for the reception of the bolts 27 by means of which and the turning levers 28 the
pillars are locked to the circular heads 29 of the double brackets 30. The bolts 27
are provided, at their upper ends, with projections having sloping faces on their
undersides which press upon sloping faces at the inside of the recesses of the
pillars. The bolts 27 are, at their lower ends, held in place by means of discs or
collars 31 into which they enter. The turning levers 28, which are welded to
the lower ends of the bolts, are all four centred towards the middle of the machine
where they are generally fastened to a plate 32 by means of loose pegs 33. The
part B is further secured in place by means of the eccentric levers 34 which press,
with their heads, at the part of greatest eccentricity, against the underside of the
ring or collar 35 of the part C of the column. These eccentric levers are fastened,
at their lower ends, by means of screws, to the base of the column. To take off
the part B it is only necessary to unfasten the locking plate 32, and to turn the
levers 28 with the locking bolts 27 so that the pillars 25 can be lifted over the
bolts, then to unfasten the screws at the lower ends of the eccentric levers and
finally to take the eccentric pins 36 out of the hooks 37 of the upper ring 35.
The under part C can, when so desired, be made to serve as a table foot or pedestal
by fitting the table top 38 upon it. This table top is provided with two hooks 39 (see
Fig. 4), which engage with the pins 36 of the eccentric levers 34, and also with two
cylindrical recesses 40 which correspond with the circular heads 29 of the double
bracket 30. The table top is fastened to the circular heads by means of the bolts 27
in the same manner as that already set forth.
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 consider novel and desire to claim is :-
1. A mangle characterized by an endless band (13) which passes between work-
ing and pressure rollers (3, 9,) and over guide rollers (15) which latter can be moved
outwards so as to stretch the band properly, substantially as set forth.
2. In a mangle such as claimed in Claim 1, the arrangement of a shaft 17 which
can be revolved by gearing and which, by means of worms (19), revolves worm
wheels (20) having bosses hexagonally hollowed for the reception of hexagonal
nuts (21) which latter can so move two adjusting screws (12) that the pressure
roller with its bearings can be removed from the columns of the machine, sub-
stantially as set forth.
3. In a mangle such as claimed in Claims 1 and 2, the arrangement of the

page_text: pillars 25 and the double brackets 30 of the columns in the recesses of which locking
bolts (27) with turning levers (28) are arranged for the purpose of ensuring the
fastening of the middle part B to the under part C, substantially as set forth.
4. In a mangle such as claimed in Claims 1 to 3, the arrangement of hooks (37)
on the frame ring (35) in which hang the eccentric levers (34) whose lower ends are
screwed to the frame, for the purpose of ensuring the connection between the
middle part (B) and the underpart (C), substantially as set forth.
5. In a mangle such as claimed in Claims 1 to 4, the combination of the lower
part (C) of the columns with a table top (38) made so as to correspond with the
circular heads of the double brackets (30) and which can be secured thereto by
means of locking bolts (27), substantially as set forth.
