Improved Drying Apparatus for Textile Fabric Paper and the
like.
I GUSTAV JAGENBURG of Rydboholm in the Kingdom of Sweden Chemist and
Manager, 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 present invention relates to a machine for the drying of fabrics, paper or the
like, heated by means of steam or a hot fluid, which requires only a small quantity of
Moreover the said drying
the heating material and effectively utilises its warmth.
machine is provided with a receiving device, which effects the removal of the fabric
or of the paper from the cylinder not only when the machine is at rest but also
during the operation at any desired moment and which facilitates the placing of the
material upon the same.
The invention is illustrated in various views and in detail in the accompanying two
sheets of drawings in which
Figure 1 is an elevation of the machine.
Figure 2 is a view from above.
Figure 3 is an axial section through Figure 2.
Figures 4 to 7 illustrate various details.
The two hollow shafts C Care connected to an axle A whose ends form the
chambers B B¹. The shafts C C¹ rest upon roller bearings Land are prolonged in a
flange B2 to which the ends of the radially arranged spokes D are screwed. In the
same manner the other end of each spoke D is connected to an angle M each of which
angles is secured at equal distances apart to the rings E E¹ respectively (see
Figures 1, 3 and 7). Each of these rings consists of as many parts as there are
heating apparatuses; these parts are connected by plates G the fixing screws whereo
are placed in slots proportionate to the expansion and contraction of the material,
(see Figure 1). The said rings are of a T-shaped section and bear at their periphery
a requisite number of bearings H (Figure 6) which are adjustably connected with the
inwardly directed angle supports of the rings E E¹ in the manner shown in Figure 7.
Several of these bearings and preferably three upon each side carry each a heating
apparatus in the form of a heating coil K (Figure 5) whose middle bolts k are firmly
fixed to the corresponding bearings H whereas the end bolts k' are so fixed in their
bearings H that they have side play corresponding to the amount of contraction and
expansion of the apparatus (see Figure 6). By means of corresponding adjustment
higher or lower of the bearing H the separate coils of the covering surface of the
cylinder can be adjusted as accurately as possible. This covering surface itself is
formed of metal plates N of which each one is soldered upon the tubular envelopes
of a heating coil K. The said metal plates N are further so connected together that
they can also expand and contract uninterruptedly (see Figure 4). At the end of
each plate there is soldered for this purpose upon the inwardly turned surface an
angle bar o, to which at regular distances eyelets 9 are attached through which
bolts b are placed and secured by means of nuts and the length of which correspond
to the expansive power of the plates.

page_text: To the inner surface of each of the rings E E' is attached a second ring T by
soldering or otherwise, which possesses a rectangular section and both of which rings
serve as a support for an insulating cover S. To each of the heating coils K are
attached two conducting tubes of which the one R serves as supply tube and connects
to the chamber B whereas the tube R connects to the chamber B' and serves as exit
tube. If the heating coils are to be heated by a liquid then there may be con-
veniently arranged a little below the axle A a vessel provided with a pump and
containing the hot fluid and the hollow shaft C may be connected by means of
stuffing boxes water-tight and revolubly to the pressure tube thereof d. The hot
fluid pumped in passes through the shaft C into the chamber B and from this through
the tube R into the heating coils K. After flowing through the same it passes
through the tubes R' into the chamber B¹ and from this through the shaft C¹ and
tubes d¹ back into the vessel in which it is again heated to its former temperature by
means of any convenient heating device. If the coils K are to be heated with steam
then the steam inlet and exit can be directly connected to the hollow shaft C or C¹
respectively in the manner shown in Figure 3.
With this machine is further connected an arrangement as already stated which
serves to remove the goods to be dried at any desired moment from the periphery of
the cylinder or to place the said goods thereupon easily and conveniently. Within
the bearing is fitted loosely both upon the shaft C as upon the shaft C' respectively
a wheel J. The said wheel J is toothed around three quarters of its periphery whilst
its remaining part is prolonged into a frame J. Attached to the said frame J¹ are
the arms a al and connected with the third arm a² in the ends of which the rollers w
and ware supported. To the bearing link of the arm a¹ is further attached a second
one which engages the revolving pin of the weaker guiding roll 2. Alongside these
wheels J are placed also loosely upon the shafts C C respectively a rack Z with inner
teething, which is prolonged towards the one side in a weighted arm m whilst on the
opposite side severally an arm m¹ is attached and connected with arms m² m³, the end
whereof serves as a support for the roller W. Between the wheel J and the racks Z
is interposed a gear wheel x. To each axle of these interposed wheels x is at the
same time attached respectively a chain wheel e and upon one thereof there is keyed
a hand wheel h. The two chain wheels e are connected together by means of the
chains t and apparatus v, so that each must share in the motion of the other.
aforesaid hand wheel be then turned in the direction of the arrow I (see Figure 1)
If the
then the roller W must move in the direction of the arrow II and the rollers w, w¹ w²
must move in the direction of the arrow III until they take up respectively the
positions shown in dotted lines.
As the goods to be dried are passed to the cylinder over the roller W and
are removed therefrom over the rollers w w¹, the same will be lifted off by this
arrangement and move in front of the cylinder by way of example in the direction
of the arrow IV without touching the same. In the same manner only in the
reversed direction the goods can be again replaced upon the cylinder.
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:-
1. A drying cylinder capable of being heated by steam or hot fluid, whose drying
surface is. formed of heating plates, wire netting, or wires N, below which are placed
heating coils K, whose connections (R and R¹) are attached to the hollow shafts C C¹
into which the inlet d and the outlet d' respectively connects.
2. In the drying cylinder characterised in Claim
removal and the placing of the goods to be dried consisting essentially, of toothed
the arrangement for the
segments Z bearing the feeding roller W and provided with counter weights, of two.
transmission wheels, coupled by means of chain gearing e tv and of two wheels J
toothed around three quarters of their periphery which together with the aforesaid
segments Z are placed loosely upon the hollow shafts C C₁ of the said cylinder and
which are prolonged in the apparatuses J', a a¹ a², in which the removing

page_text: rolls www are revolubly supported in such a manner that by the revolution of the
transmission gear wheels the said rollers are moved in a direction opposite to one
another and so far in a circle concentric to the cylinder until the said rollers have
removed the goods to be dried from the cylinder or have placed the same thereupon
