PROVISIONAL SPECIFICATION.
Improvements in Machines for Calendering Fabrics and the like.
I, JULIUS GEBAUER, of No. 87c, Berliner Strasse, Charlottenburg, near Berlin,
Kingdom of Prussia, in the German Empire, Manufacturer, do hereby declare
the nature of this invention to be as follows:
-
This invention relates to a machine for calendering fabrics and the like, and
more particularly to the attachment to the bearings which carry the top-roller,
of lever-mechanism for regulating the pressure of the said roller upon the material
being calendered, so as to permit of casily setting the said top-roller to any
diameter of the roller on which the fabric or other material to be treated is
wound.
The lower roller of the machine is carried in stationary bearings in the frame
while the top-roller is mounted in sliding-bearings to which a lever-system is
connected. Sliding blocks are adapted to be moved up or down in the frame of
the machine by means of two screw-spindles fitting into screw-threaded sockets
or nuts formed on the said blocks. During the downward motion of the slide-
blocks the weighted lever connected thereto is lifted from the support, thereby
causing the said lever to apply the pressure for the calendering after the roller
with the material wound thereon is introduced between the top and the lower
roller. The position of the movable weight upon the lever is adjusted by means
of a chain carried over guide-rollers and adapted to be operated by a hand wheel
mounted upon the weighted lever. The said hand wheel can be operated in
such a manner as to suit any required pressure.
In order to limit the swinging motion of the levers of the said system due to
the unevenness of the roller carrying the material it is advantageous to remov-
ably connect with the weighted lever any convenient disengaging device for
lifting the belt-fork, as soon as the lever recedes too far from its support.

page_text: 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 for calendering fabrics and the like, and
more particularly to the attachment to the bearings which carry the top-roller
of lever-mechanism for regulating the pressure of the said roller upon the material
being calendered,. so as to permit of easily setting the said top-roller to any
diameter of the roller on which the fabric or other material to be treated is
wound.
In order to enable my invention to be clearly understood I will describe the
same with reference to the accompanying drawing, in which:
Fig. I is an end-elevation of a calendering machine constructed according
to my invention,
Fig. II is a front-elevation of the same,
Fig. III is a sectional view illustrating diagramatically the arrangement of
the lever mechanism and rollers,
Fig. IV is a horizontal section taken on the line a, b of Figure I and
Figure 5 is similar section taken on the line c-d of Figure I.
The machine frame A is provided with stationary bearings supporting a bot-
tom roll W while the top roll V is journalled in blocks B which can be moved
up and down in the machine frame. For this purpose the guiding pieces P' to
which the lever arrangement H is attached, are provided with nuts N through
which pass the sorew spindles M which can be rotated by the worm wheels C, D),
so that when the spindles are rotated in one direction or the other, the nuts N
and consequently the guiding pieces P are raised or lowered. The driving of
both wheels C and D is effected by means of a worm O provided on the shaft E.
The weighted lever H pivoted to the arm S provided on one of the guiding pieces
has linked to it the lever arrangement I and is connected to the blocks B through
the rods K. If a roll having wound on it the material to be treated, is inserted
between rollers V and W and the guiding pieces P are lowered by means of the
screw-spindles M, weighted lever H will be freed from its support or rest F',
so that the calendering pressure will be exerted through weighted lever H on
the top roll and that on which the material is wound. For the purpose of regu-
lating the calendering pressure, I provide on lever Ha weight G, the position
of which can be altered by means of a hand-wheel R and a chain passing over the
roller K so that the calendering pressure can be adjusted by shifting the
weight G. For the purpose of limiting the up and down oscillating motion of
the levers, due to the uneveness of the roller carrying the material, I provide a
throwing-in-and out-of gear device operating in the usual manner. This device
is arranged as follows:
Lever H has attached to it a tappet Z. The belt fork T of the driving device
provided on the shaft E by means of which device the nuts of the guiding pieces P
are raised or lowered, is connected by a lever mechanism. U with a rod L. This
rod L is provided with adjustable nuts W, W³, and passes through a slot in
the tappet Z of the lever H. When the oscillation of the lever H during the
down movement of the guiding pieces is too great, the tappet Z strikes on one
of the nuts W, W of the rod L. In consequence thereof the belt fork T of
the driving device is shifted by means of the lever mechanism from the fixed
pulley to the loose pulley whereby the down movement of the guiding pieces
is interrupted.
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:-
A calendering machine having a stationary bottom roller and characterised
by the feature that the fulcrums of the lever mechanism for regulating the pres-
sure on the top-roller are located in the guiding pieces and that the said top
roller is suspended from the lever mechanism, so that the downward motion of

page_text: the screw-threaded nuts provided on the guiding pieces causes the weighted
lever, the weight of which is adjusted to the pressure required, to be lifted from
its support, substantially as described and shown on the accompanying drawing.
