PROVIDIUNAL SPECIFICATION.
Improvements in Drying Machines.
I, ELIAS TOBLER, of Ponte S. Pietro, near Bergamo, in the Kingdom of Italy,
Mechanician, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a drying machine in which a rotary drum
with two rows of goods holders which are adjustable as regards one another in
their cross pieces or cross bars is provided inside a drying house. The goods
holders are guided on bars in the drying house in such a way that the goods to
be treated are engaged by the goods holders which are conveyed convergingly
to one another and thereupon strained or stretched by the diverging goods
holders. A hot air current travelling in an opposite direction to the moving
goods in the drying house serves for drying the stretched goods.
In the forms of construction of drying machines hitherto employed the goods
holders were in connection with continuous chains. These chains had consider-
able defects, more particularly in that the links of the chains were constantly
wearing away in their pins and guides. The chains also expanded in use which
had for a consequence that they no longer fitted in the guide grooves and
consequently had to be subjected to time-consuming expensive repairs. As
the chains in their whole length run in grooves and by the stretching of the
goods during the working a very strong friction is caused, a considerable
expenditure of power was necessary to operate them.
All these drawbacks are removed by the present invention. The goods holder
is simplified; it travels easily on guide rollers and in guide slots; is easily
changed or replaced without special disturbances of working and may in con-
sequence of its arrangement and guidance be made considerably longer than
the goods holders on the chains, consequently it is possible to reduce the number
of goods holders from for instance 700 to 120.
A further advantage results from the arrangement of the closed drying house,
as the hot air remains in action during the whole transit and must flow through
with greater friction against the passage of the goods.
In the accompanying drawings two forms of construction of the drying
machine are shown as examples. Figures 1-13 represent the drying machine
with the goods holders arranged with pins on which the goods may be impaled,
whilst the drying machine shown in Figures 14-24 employs clutches or claws
as goods holder.

The drying machine shown in a general view in Figures 1 and 2 consists of
a drum mounted on a shaft and having goods holders and a drying chamber
or casing c surrounding the drum and provided with a means for guiding the
goods holders. The drum bis formed of two wheels 662 which are connected
with one another by cross pieces on their periphery. Under the cross pieces
between the wheels a closing casing e is provided, Figures 5 and 7.
In the cross pieces there are provided slots in which goods holders fare
mounted in such a way as to be adjustable as regards one another."
The goods holder, Figures 9, 10 and 11 consists of a guide piece f¹ travelling
in the slot d of the cross bar and carrying a spiked bar holder f revoluble
with an axle in the guide piece. In this holder the spiked bar f4 is fixed
by means of screws in such a way as to be easily removable. A lever f mounted
in the guide piece lies above with two arms against the spiked bar holder' f³,
whilst it is held under tension beneath the guide piece by means of a spiral
spring fso that it has a tendency to return the pin bar holder f³ pivotting on
the spindle f to its middle position. There are also provided on the guide
piece a roller f revoluble on a vertical shaft and a pin f8 between which two
the goods holder slides into the hereinafter described guide.
The drying casing or chamber c consists of two lateral walls c' which extend
closely to the drum wheels and a casing or covering c² around its periphery.
Between the walls a number of screw bolts are revolubly mounted (for
instance in the drawing 6 are shown). The screw bolts have at one end a chain
wheel over which a chain 2 embracing all the chain wheels engages. One
of the screw bolts Figures 5 and 6, carries on the other end a toothed wheel g
which gears with a toothed wheel revoluble by means of a crank g. By
turning this screw bolt all the others may be rotated by means of the chain
The screw bolts have each a right and left hand thread pitched in opposite
directions. With these threads they engage into nuts on frames 4 mounted on
two rings h. The rings serve as guides for the goods holders f and may be
approached together or moved apart by means of the screw bolts.
The guides of the guide holders must be formed in such a way that the goods
holder for the purpose of receiving the smaller goods to be dried may be
approached together and then somewhat moved apart in order to stretch the
goods across their width, after which they may be again guided further parallel
to one another in the stretched position for the prosecution of the further drying
process. For this object a device is inserted in the rings which renders this
procedure possible. The rings h which are formed of angle irons, and on the
vertical arms of which rollers of the goods holders travel on the inner side
and piis on the outer side, have on certain portions a recess 2 Figs. 8
and 13 between two hinges (Figure 6) through which recess the rollers f

page_text: may emerge or project. Between the hinges i and on each ring a triangular
jointed guide bar is, hinged or pivotted. The two guide bars lying
opposite one another converge with their lowest link or member k, Figure 0,
then run with their middle members ¹ parallel for a time and then diverge with
their upper members until the guide hinges ¹ out of the ring again become
parallel. Correspondingly the goods holders guided by means of the roller f
on the guide bars must make the intended or designed movements.
!.
In order to adjust the goods holders according to the width of the goods to be
carried, the members or parts of the guide bar kare, adjustable in regard
to one another by means of. a.shaft 1. This is of rectangular, formi and carries
a sleeve adjustable on it for each slide bar and having a threaded projection
which is screwed into a ring or union on the ring in question, Figure 6. The
middle member of the slide bar is traversed by the sleeve and the latter
is secured against displacements in the part in front, and. behind the said
part by means of discs and . The part has a lateral.extension which
is guided as a carriage between checks on the ring (Figures 8, 12 and 13).
By revolving the rectangular spindle by means of a hand-wheel 15. mounted
on the end, the slide bars may be approached, to one another or moved apart.by
means of the sleeve, the threads of which are pitched in opposite directions.
On each central part there is a two armed lever m pivotting on a spindle m,
one arm of which lever carries a brush m² whilst on the other arm, a spiral
spring m engages and tends to draw the same upwards, consequently the other
arm with the brush must move downwards and the. latter therefore rests with
some pressure on the spiked bars of the goods holder passing beneath it. The
brush m² has for its object to brush the goods z, Figure 5, brought up with
pressure on the spiked bar so that they remain adhering on the spikes.
In order to characterize the correct central position of the goods introduced,
two pins o, Figures 5 and 6, are adjustably arranged on a screw shaft o' having
two opposite threads and adjustable by means of a hand wheel o at the side,
and pins being on the outside of the drying chest in front of the inlet.
The inlet and outlet for the goods on the drying chest or chamber are formed
of three hollow cylinders 77. The goods may pass between the upper
hollow cylinders into the drying chamber and out between the lower
hollow cylinders A folding apparatus r, Figure 1, also serves to fold in
the ordinary manner the dried goods emerging from the machine. A pipe q¹
coming from a steam boiler or heating boiler opens into the drying chamber
beneath the exit, Figure 1. The dry chamber is carried by four supports s,
Figures 1, 2, 3 and 4, in such a way that when it becomes heated it may freely
expand in all directions without thereby coming out of the common axis of
the drums. For this object the casing rests by means of screws s', Figures 3
and 4, on supports which are adjustable on the supports in the direction of its
expansion. In order to prevent a so-called hanging over or suspension of the
drying chamber, that is to say in order to prevent its shape being altered by
the burden of its own weight above and below, devices for. relieving the weight
in the form of levers and counterweights t are arranged. A ring with
internal teeth in which a driving apparatus engages in the ordinary manner is
provided on the sides of the drum, Figures 2 and 7.
The method of working of the drying machine described is as follows:-
After the guide rings have been adjusted by means of the screw bolts in
such a way that the space between the central parts of the guide bars and
the goods holders sliding there have been adjusted to agree with the width of
the goods to be dried, the drum together with its goods holders is set in
movement. The goods holders then describe the course hereinbefore detailed
on the guide rings and guide bars. The goods are then brought between pins
into the central position and introduced between the hollow cylinders p' p²
into the drying chamber. In the latter the goods are pressed by the brushes m³
on the two needle bars of the goods holders passing between them which in this
0

page_text: position have the nearest position to one another on the parts of the slide bars.
The goods holders pass with the goods on to the parts of the slide bars,
diverge on the same and thereby stretch the goods. The guide rings assume
the further guidance of the goods holders in a parallel direction until the goods
holders reach the converging parts k of the slide bars and automatically remove
the tension on the goods and the latter can pass between the hollow cylinders
and 23 out of the drying chamber on to the folding apparatus r. Whilst the
goods are conveyed through the drying machine, hot air flows through the
supply pipe q¹ out of the heating boiler q into the drying chamber, traverses
the latter in a direction opposite to that in which the goods are conveyed and
effects their drying. The used dry air may be carried off above the goods entrance
by means of a suitable opening, chimney shaft or the like which is not shown
in the drawing.
In the modified form of construction shown in Figures 14-24, instead of
the goods holders having needles they are made in a clutch form. These goods
holders which otherwise are similarly constructed to those previously described
have in place of the spiked holder a clutch v consisting of a revoluble or movable
under part on which an upper part (a so-called "burr") is laterally mounted
by means of double hinges and on a curved piece v. Pins are provided
on the loop piece and also on the upper part, on which pins a device for
opening and closing the clutch engages on the passing of the clutch over the
slide bars k k 12. The slide bar carries a guide rail or bar www2 adjustable
(Figures 22, 23, and 24) in slots of bent over flaps j, which guide
bar travels parallel and is fixed to said guide bar on its parts k, k².
At first the guide rail has a curve with a tongue which engages
during the operation the approaching clutch between the pins and
and then the burr and travelling further along the pins also turns back the
curved piece so that the clutch is opened and in this condition guides itself on
the guide rail on which the pins and travel on both sides. The bent part
provided on the other end of the guide bar www which bent part also extends
into a tongue w¹, again raises the loop and after quitting the guide rail a
scraping iron or scraper w provided behind a guide bar and fixed with a light
spring action on the centre bar comes into action, the burr being raised on
the same by the pin travelling over it and resting on the under part of the
clutch clamping between itself and the clutch the goods in the meantime placed
thereon. From this point forward no further guidance is necessary for the
clutch in order to keep the said clutches closed up to the place where the goods
are discharged, because by the strain of the goods expanding the clutches are
always closed more tightly.
The insertion of the goods in the clutches is effected by means of three
rollers 2, one of which a serves in the centre as a central guide for the
goods while the other two a extend over the under parts of the open clutches
and spread out the goods, Figure 19. After the clutches have been opened by
the tongue w³ and by the successive or following bending of the guide bars
the goods still linger a period on the under part until they are drawn behind
rollers y similar to the rollers and may be removed from the drying
machine.
A so called scraper or scraping iron provided with an inclined plane,
Figure 22, is further provided in front of the tongue on the guide ring h.
This scraper has for its object when the machine is travelling empty when possibly
the upper parts of the clutches lie automatically on the side or open on passing
by to raise them in order that the guide bar with its tongue w³ can be correctly
caught between the pins 7. In the other parts the construction of this modified
form corresponds to that of the first one described.
In the last described form of the goods holder the clutches may be changed
for a spiked bar. For this object the under part on which the whole remaining
parts of the clutch are mounted may be withdrawn from the guide piece f' in

page_text: which it is pivotally mounted on a pin fafter a nut mounted on said pin has
been removed and may be replaced by a spiked holder similar to the one shown
in Figures 9, 10 and 11. This spiked holder has a similar pin f to that of the
under part of the clutch which finds a suitable support in a guide piece f¹.
The height of the spiked roller from the guide piece must be measured to be
similar to the height of the under part of the clutch.
The modification in the drying machine may be effected in the changing of
the goods holders by removing the inserting rollers and replacing them by
brushes (such as m² of Figures 5 and 6). In its other parts the machine remains
unaltered.
Improvements in Drying Machines.
I, ELIAS TOBLER, of Ponte S. Pietro, near Bergamo, in the Kingdom of Italy,
Mechanician, 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 has for its object a drying machine in which a rotary drum
with two rows of goods holders, which are adjustable as regards one another in
their cross pieces or cross bars, is provided inside a drying house. The goods
holders are guided on bars in the drying house in such a way that the goods to
be treated are engaged by the goods holders which are conveyed convergingly
to one another and thereupon strained or stretched by the diverging goods
holders. A hot air current travelling in an opposite direction to the moving
goods in the drying house serves for drying the stretched goods.
In the forms of construction of drying machines hitherto employed the goods.
holders were in connection with continuous chains. These chains had consider-
able defects, more particularly in that the links of the chains were constantly
wearing away in their pins and guides. The chains also expanded in use which
had for a consequence that they no longer fitted in the guide grooves and
consequently had to be subjected to time-consuming expensive repairs. As
the chains in their whole length run in grooves and by the stretching of the
considerable
goods during the working a very strong friction is caused, a
expenditure of power was necessary to operate them.
All these drawbacks are removed by the present invention. The goods holder
is simplified; it travels easily on guide rollers and in guide slots; is easily
changed or replaced without special disturbances of working and may in con-
sequence of its arrangement and guidance be made considerably longer than
the goods holders on the chains, consequently it is possible to reduce the number
of goods holders from for instance 700 to 120.
A further advantage results from the arrangement of the closed drying house,
as the hot air remains in action during the whole transit and must flow through
with greater friction against the passage of the goods.
In the drawings accompanying the Provisional Specification, two forms of
construction of the drying machine are shown as examples. Figures 1-13 re-
present the drying machine with the goods holders arranged with pins on which
the goods may be impaled, whilst the drying machine shown in Figures 14-24
employs clutches or claws as goods holder.

The drying machine shown in a general view in Figures 1 and 2 consists of
a drum b mounted on a shaft and having goods holders and a drying chamber
or casing c surrounding the drum and provided with a means for guiding the
goods holders. The drum b is formed of two wheels which are connected
with one another by cross pieces d on their periphery. Under the cross pieces
between the wheels a closing casing e is provided, Figures 5 and 7.
In the cross pieces d there are provided slots d'in which goods holders f are
mounted in such a way as to be adjustable as regards one another.
The goods holder, Figures 9, 10 and 11, consists of a guide piece f¹ travelling
in the slot d' of the cross bar and carrying a spiked bar holder revoluble
with an axle f in the guide piece. In this holder f3 the spiked bar f is fixed
by means of screws in such a way as to be easily removable. A lever mounted
in the guide piece lies above with two arms against the spiked bar holder f³,
whilst it is held under tension beneath the guide piece by means of a spiral
spring f so that it has a tendency to return the pin bar holder pivotting on
the spindle to its middle position. There are also provided on the guide
piece fa roller revoluble on a vertical shaft and a pin f8 between which two
the goods holder slides into the hereinafter described guide.
The drying casing or chamber c consists of two lateral walls c¹ which extend
closely to the drum wheels and a casing or covering c² around its periphery.
Between the walls c¹ a number of screw bolts are revolubly mounted (for
instance in the drawing 6 are shown). The screw bolts have at one end a chain
wheel glover which a chain g³ embracing all the chain wheels engages. One
of the screw bolts g Figures 5 and 6 carries on the other end a toothed wheel g
which gears with a toothed wheel revoluble by means of a crank go. By
turning this screw bolt all the others may be rotated by means of the chain g².
The screw bolts g have each a right and left hand thread pitched in opposite
directions. With these threads they engage into nuts on frames h¹ mounted on
two rings h. The rings h serve as guides for the goods holders f and may be
approached together or moved apart by means of the screw bolts.
The guides of the goods holders must be formed in such a way that the goods

page_text: holder for the purpose of receiving the smaller goods to be dried may be
approached together and then somewhat moved apart in order to stretch the
goods across their width, after which they may be again guided further parallel
to one another in the stretched position for the prosecution of the further drying
process. For this object a device is inserted in the rings which renders this
procedure possible. The rings h which are formed of angle irons, and on the
vertical arms of which rollers of the goods holders travel on the inner side
and pins on the outer side, have on certain portions a recess 2 Figures 8
and 13 between two hinges i i¹ (Figure 6) through which recess the rollers f
may emerge or project. Between the hinges i and on each ring a triangular
jointed guide bar kis hinged or pivotted. The two guide bars lying
opposite one another converge with their lowest link or member k, Figure 6,
then run with their middle members parallel for a time and then diverge with
their upper members until the guide hinges ¹ out of the ring again become
parallel. Correspondingly the goods holders guided by means of the roller f
on the guide bars must make the intended or designed movements.
In order to adjust the goods holders according to the width of the goods to be
carried, the members or parts of the guide bar are adjustable in regard
to one another by means of a shaft . This is of rectangular form and carries
a sleeve adjustable on it for each slide bar and having a threaded projection
which is screwed into a ring or union on the ring in question, Figure 6. The
middle member of the slide bar is traversed by the sleeve and the latter
is secured against displacements in the part in front and behind the said
part by means of discs and 14. The part has a lateral extension n which
is guided as a carriage between cheeks n¹ on the ring (Figures 8, 12 and 13).
By revolving the rectangular spindle 7 by means of a hand-wheel mounted
on the end, the slide bars may be approached to one another or moved apart by
means of the sleeve , the threads of which are pitched in opposite directions.
On each central part there is a two armed lever m¹ pivotting on a spindle m
one arm of which lever carries a brush m² whilst on the other arm a spiral
spring m³ engages and tends to draw the same upwards, consequently the other
arm with the brush must move downwards and the latter therefore rests with
some pressure on the spiked bars of the goods holder passing beneath it. The
brush m² has for its object to brush the goods z, Figure 5, brought up with
pressure on the spiked bar so that they remain adhering on the spikes.
In order to ensure the correct central position of the goods introduced,
two pins o, Figures 5 and 6, are adjustably arranged on a screw shaft of having
two opposite threads and adjustable by means of a hand wheel o² at the side,
said pins being on the outside of the drying chest in front of the inlet.
The inlet and outlet for the goods on the drying chest or chamber are formed
of three hollow cylinders p¹². The goods may pass between the upper
hollow cylinders p¹² into the drying chamber and out between the lower
hollow cylinders 23. A folding apparatus r, Figure 1, also serves. to fold in
the ordinary manner the dried goods emerging from the machine. A pipe
coming from a steam boiler or heating boiler opens into the drying chamber
beneath the exit, Figure 1. The dry chamber is carried by four supportss,
Figures 1, 2, 3 and 4, in such a way that when it becomes heated it may freely
expand in all directions without thereby coming out of the common axis of
the drums. For this object the casing rests by means of screws s¹, Figures 3
and 4, on-supports s which are adjustable on the supports in the direction of its
expansion. In order to prevent a so-called hanging over or suspension of the
drying chamber, that is to say in order to prevent its shape being altered by
the burden of its own weight above and below, devices for relieving the weight
in the form of levers t and counterweights are arranged. A ring with
internal teeth in which a driving apparatus engages in the ordinary manner is
provided on the sides of the drum, Figures 2 and 7.
The method of working of the drying machine described is as follows:-

page_text: After the guide rings h have been adjusted by means of the screw bolts gin
such a way that the space between the central parts of the guide bars and
the goods holders sliding there have been adjusted to agree with the width of
the goods to be dried, the drum together with its goods holders is set in
movement. The goods holders then describe the course hereinbefore detailed
on the guide rings and guide bars. The goods are then brought between pins o
into the central position and introduced between the hollow cylinders p¹ 22
into the drying chamber. In the latter the goods are pressed by the brushes m³
on the two needle bars of the goods holders passing between them which in this
position have the nearest position to one another on the parts of the slide bars.
The goods holders pass with the goods on to the parts of the slide bars,
diverge on the same and thereby stretch the goods. The guide rings assume
the further guidance of the goods holders in a parallel direction until the goods
holders reach the converging parts of the slide bars and automatically remove
the tension on the goods and the latter can pass between the hollow cylinders 2
and 23 out of the drying chamber on to the folding apparatus r. Whilst the
goods are conveyed through the drying machine, hot air flows through the
supply pipe q out of the heating boiler q into the drying chamber, traverses
the latter in a direction opposite to that in which the goods are conveyed and
effects their drying. The used dry air may be carried off above the goods entrance
by means of a suitable opening, chimney shaft or the like which is not shown
in the drawing.
In the modified form of construction shown in Figures 14 to 24, instead of
the goods holders having spikes they are made in a clutch form.
These goods
holders which otherwise are similarly constructed to those previously described
have in place of the spiked holder a clutch v consisting of a revoluble or movable
under part on which an upper part 5 (a so-called "burr") is laterally mounted
by means of double hinges and 3 on a curved piece v. Pins are provided
on the loop piece and also on the upper part 5, on which pins a device for
opening and closing the clutch engages on the passing of the clutch over the
slide bars. The slide bar carries a guide rail or bar www² adjustable
(Figures 22, 23 and 24) in slots j₁ of bent over flaps j, which guide
bar travels parallel and is fixed to said guide bar on its parts k k¹.
At first the guide rail has a curve with a tongue which engages
during the operation the approaching clutch between the pins 6 and 7
and then the burr, and travelling further along the pins also turns back the
curved piece so that the clutch is opened and in this condition guides itself on
the guide rail on which the pins and 7 travel on both sides. The bent part
provided on the other end of the guide bar www which bent part also extends
into a tongue w, again raises the loop and after quitting the guide rail a
scraping iron or scraper provided behind a guide bar and fixed with a light
spring action on the centre bar 62 comes into action, the burr being raised on
the same by the pin travelling over it and resting on the under part of the
clutch, clamping between itself and the clutch the goods in the meatime placed
thereon. From this point forward no further guidance is necessary for the
clutch in order to keep the said clutches closed up to the place where the goods
are discharged, because by the strain of the goods expanding the clutches are
always closed more tightly.
The insertion of the goods in the clutches is effected by means of three
rollers 2, one of which 2 serves in the centre as a central guide for the
goods while the other two al extend over the under parts of the open clutches
and spread out the goods, Figure 19. After the clutches have been opened by
the tongue and by the successive or following bending of the guide bars
the goods still linger a period on the under part until they are drawn behind
rollers y similar to the rollers and may be removed from the drying
machine.
A so called scraper or scraping iron z¹ provided with an inclined plane,

page_text: Figure 22, is further provided in front of the tongue 3 on the guide ring h.
This scraper has for its object when the machine is travelling empty when possibly
the upper parts of the clutches lie automatically on the side or open on passing
by to raise them in order that the guide bar with its tongue w³ can be correctly
caught between the pins 7. In the other parts the construction of this modified
form corresponds to that of the first one described.
In the last described form of the goods holder the clutches may be changed
for a spiked bar. For this object the under part on which the whole remaining
parts of the clutch are mounted may be withdrawn from the guide piece fl in
which it is pivotally mounted on a pin f2 after a nut mounted on said pin has
been removed and may be replaced by a spiked holder similar to the one shown
in Figures 9, 10 and 11. This spiked holder has a similar pin f to that of the
under part of the clutch which finds a suitable support in a guide piece fl.
The height of the spiked roller from the guide piece must be measured to be
similar to the height of the under part of the clutch.
The modification in the drying machine may be effected in the changing of
the goods holders by removing the inserting rollers and replacing them by
brushes (such as m² of Figures 5 and 6). In its other parts the machine remains
unaltered.
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 machine for stretching and drying fabrics having a drum provided with
two different rows of horizontally pivotal goods-holders mounted on its periphery
and diverging from one another, said goods holders being compulsorily guided on
fixed bars adjustable as regards one another inside a fixed drying chamber
surrounding the drum, and said drying chamber being traversed by a current of
hot air in a direction opposite to that in which the goods are conveyed, the whole
being adapted to give the stretching apparatus a simple, sure, and durable guid-
ance, requiring comparatively little driving power, within a closed drying chamber,
whilst avoiding the chain and wheel guidance hitherto employed, substantially
as hereinbefore described.
2. A machine for stretching and drying fabrics, having removable pivotal
goods-holders arranged in two rows diverging as regards one another on the
periphery of a drum within a fixed drying chamber and receiving compulsorily
the movement prescribed for stretching the goods, on fixed bars adjustable against
one another, the drying chamber being traversed by a hot air current in an
opposite direction to that in which the goods are conveyed, and the goods holders
being set with spikes on which the goods are impaled during their passage
through the drying chamber substantially as described.
3. A machine for stretching and drying fabrics, having removable pivotal
goods-holders arranged in two rows displaceable against one another on the
periphery of a drum within a fixed drying chamber, and compulsorily receiving
the movement prescribed for stretching the goods on fixed bars adjustable as
regards one another, the drying chamber being traversed by a hot air current
in a direction opposite to that in which the goods are conveyed, and the goods
holders being removable in such a way that the clutches may be removed from
the guide pieces and replaced by spiked holders secured in a similar manner to
the clutches, substantially as described.
4. A machine for stretching and drying fabrics, having removable pivotal
goods-holders arranged in two rows displaceable against one another on the peri-
phery of a drum within a fixed drying chamber and compulsorily receiving the
