PROVISIONAL SPECIFICATION.
Improvements in Feeding Devices for Drying Apparatus and the like.
I, GEORG PETERS, of Langenberg-Furstenflagge, in the Province of Pommein,
German Empire, Engineer, do hereby declare the nature of this invention to be as
follows:
-
This invention relates to a teeding device adapted for an apparatus or plant for
drying wet peat, turmp cuttings or peelings and like material
The drying apparatus consists, as shown in the accompanying diawings, in
Figures 1 & 2 of a rotating drum y which drum 18 penetrated by a number of
tubes Figures 3 & 4 represent a modification of my improved device, whilst
Figures 3, 3 and 3º, as well as Figure 4 show the method of producing the
Oscillating movement of said device.
The material to be dried is introduced into the hopper d and reaches the tubes f
in a finely divided state and by its slow passage through the said tube becomes
dried by the influence of the steam issuing from the holes h¹ of the wide centially
aranged steam-tube h
Said rotating drum iests with its studs or pins b in the beating c, in which studs
o pins an aperture is provided, through which the steam is introduced into the
said cential steam tube h
The improved feeding-device forming the subject of my invention is shown in
Figures 1 & 2, and, as above stated, in Figures 3 & 4 in a modified construction
The construction of my improved feeding device shown in Figures 1 & 2
consists of a number of cylindrical pistons provided with spoon-like projections 1.
The pistons are connected by 1ods to cranks of the diving-shaft m, as shown
in the drawing, Figure 1
k
It will be further seen from the diawing (Figures 1 & 2) that I have illustrated
as an example three pistons the cranks of which are airanged of course at an
angle of 120° to each other. The pistons k form with their spoon-like projections n
a kind of ramming device, and operate in the following manner:
06
In the movement of the said pistons in the duection of the plate a these pistons
with their spoon-like projections piess the material to be dried into the drying
tubes, for the reason that these pistons can execute, "besides" a forward and
backward, or to- and fro-movement, also an oscillating" movement, as will be
hereinafter more fully described, thus the material in the hopper will be pressed
together, by means of which, further space in the hopper will become fiec, or
in other words, this oscillating action will tend to clear the hopper and will, as
18 apparent, tend to facilitate or accelerate the introduction of fresh material into
the said hopper
The action of the said pistons & is thus, as it were, a double action for firstly,
as above indicated, the said pistons effect the duect forcing of the goods to be
dried into the diving tubes, and secondly the said pistons by the oscillating
action above refered to favorably influence, as also above refeiied to, the intro-
duction, of fresh material into the hopper
The modification shown in Figures 3 & 4 is such, that a kind of endless woim or

page_text: spiral takes the place of the pistons, for the purpose of transporting the material
into the drying tubes, said endless worms or spirals (forcing the material into
the said drying tubes), being also actuated by shafts p driven by the bevel-
gear q, from the shaft p.
In order also in this construction to accelerate the partial emptying of the
hopper, so as to make 100m for fresh material, the ends of the said shafts pl
(Figures 3 & 4) may be provided with extensions in the form of a piston, cach
shaft p being provided with a amilar extension, and as these shafts p' can
also perform a rotating and oscillating movement, as hereinafter shown in
Figures 3-4, it is clear that the emptying of the hopper will be accelerated, in
just the same manner as shown with reference to the consti uctions in Figures 1 & 2
In Figure 3 I show a bearing suitable for employment in connection with
the endless worm of Figs 3 & 4, from which Figure 3 it will be seen, that the
.shaft is free to perform an oscillating movement, as indicated by dotted lines
Figures 3 and 3 show a movable bearing or plummer-block which permits the
shaft to perform an oscillating movement (in consequence of the said plummel-
block or bearing being movable upon the pins or studs 3) This oscillating
movement is shown in dotted lines in Figure 3.
Figure 4 shows a more direct method by means of which the oscillating move-
ment of the shaft can be attained, in which construction this oscillating move-
ment 18 effected by the employment of a movable bearing , a diving iod c, a
crank or eccentric wheel co, and straps e diven by the main abaft The operation
of this mechanism is clearly illustrated and should need no further explanation
I am aware that revolving dying drums provided with feeding-devices are
known, my invention however, relates to the arrangement of a feeder having a to-
and fio-movement and at the same tune, or in combination with this movement,
an up- and down- or oscillating motion imparted to the said feeding device in any
suitable manner, from which it will be clear, that I may reserve the night of
slightly varying the means by which I attain the said object, without departing
from the principle of my invention

Improvements in Feeding Devices for Drying Apparatus and the like,
I, GLORG PETERS, of Langenberg-Furstenflagge, in the Province of Pommern,
German Empire, Engineer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly descubed and
ascertained in and by the following statement:
This invention relates to a feeding device adapted for an apparatus or plant for
diying wet peat, turnip cuttings or peelings and like material
The drying apparatus consists, as shown in the drawings filed with the
Provisional Specification, in Figures 1 & 2, of a rotating drum which 18
penetrated by a number of tubes Figures 3 & 4 represent a modification of my
improved device whilst Figures 3, 3 and 3, as well as Figure 4, show the
method of producing the oscillating movement of said device
The material to be dried is introduced into the hopper d and caches the tubes f
in a finely divided state and by its slow passage through the said tube becomes

page_text: dried by the influence of the steam issuing from the holes h¹ of the wide centrally
arranged steam-tube h
Said rotating dium rests with its studs or pins in the beamng, in which studs
or pins an aperture 1 18 provided, through which the steam is introduced into the
said central steam tube h
The improved feeding-device forming the subject of my invention is shown in
Figures 1 & 2, and, as above stated, in Figures 3 & 4 in a modified construction
The construction of my improved feeding device shown in Figures 1 & 2
consists of a number of cylindrical pistons & provided with spoon-like projections n
The pistons are connected by rods to cianks 7 of the driving-shaft m, as shown
in the drawing, Figure 1
It will be further seen from the drawing (Figures 1 & 2) that I have illustrated
as an example three pistons the cranks of which are arranged of course at au
angle of 120° to each other The pistons form with then spoon-like projections
a kind of ammung device, and operate in the following manner
In the movement of the said pistons in the duection of the plate a these pistons
with their spoon-like projections press the material to be dried into the drying-
tubes, for the reason that these pistons & can execute, "besides " a forward and
backward, or to- and fio-movement, also an "oscillating" movement, as will be
hereinafter more fully descubed, thus the material in the hopper will be pressed
together, by means of which, further space in the hopper will become fice, or
in other words, this oscillating action will tend to clear the hopper and will, as
is apparent, tend to facilitate oi accelerate the introduction of fresh material into
the said hoppei
The action of the said pistons & is thus, as it were, a double action, for:
Firstly, as above indicated, the said pistous effect the duect forcing of the
goods to be dried into the dying tubes, and
ន៍
Secondly, the said pistons by the oscillating action above referred to favorably
influence, as also above referred to, the introduction of fresh material into the
hopper.
The modification shown in Figures 3 & 4 18 such, that a kind of endless worm or
spiral takes the place of the pistons, for the purpose of transporting the material
into the drying tubes, said endless worms oi spals (forcing the material into
the said diying tubes), being also actuated by shafts driven by the bevel-
gear q, from the shaft p.
In order also in this construction to accelerate the partial emptying of the
hopper, so as to make 100m for fresh material, the ends of the said shafts pl
(Figs. 3 & 4) may be provided with extensions, in the form of a piston, each
shaft p being provided with a similar extension, and as these shafts p¹ can
also perform a rotating and oscillating movement, as hereinafter shown in
Figures 3-4, it is clear that the emptying of the hopper will be accelerated in
just the same manner as shown with reference to the constructions in Figures 1 & 2.
In Figure 3 I show a bearing suitable for employment in connection with
the endless woim of Figs 3 & 4, from which Figure 3 it will be seen, that the
shaft is free to perform an oscillating movement, as indicated by dotted lines
Figures 3 and 3 show a movable bearing or plumber-block which permits the
shaft to perform an oscillating movement (in consequence of the said plumber-
block or bearing being movable upon the pins or studs ). This oscillating
movement is shown in dotted lines in Figure
Figure 4 shows a more direct method by means of which the oscillating move-
ment of the shaft can be attained, in which construction this oscillating move-
ment is effected by the employment of a movable bearing e, a diving iod ', a
ciank or eccentric wheel 6, and straps & duiven by the main shaft
The operation
of this mechanism is clearly illustiated and should need no further explanation
I am aware that evolving drying drums provided with feeding-devices are
known, my invention however, relates to the arrangement of a feeder having a to-
and fro-movement and at the same time, or in combination with this movement,

page_text: an up- and down- or oscillating motion imparted to the said feeding device in any
suitable manner, from which it will be clear, that I may reserve the right of
slightly varying the means by which I attain the said object, without departing
from the principle of my invention
Having now particularly described and ascertamed the nature of my said
invention, and in what manner the same 16 to be performed, I declare that what
I claim is:
A feeding-device for drying-apparatus, substantially as described in the fore-
going specification and illustrated in the drawings.
