PROVISIONAL SPECIFICATION.
An Improved Process and Apparatus for Producing Depressed or
Raised Patterns on Felt Hats, Felt, Cloth, or the like.
I, MAX WILKE, of Guben in the Empire of Germany, Hat Manufacturer, do
hereby declare the nature of this invention to be as follows:-
Repeated attempts have already been made to provide felt hats with depressed
or raised patterns, such patterns being produced by pressure.
In the case of women's hats which are generally protected from the rain, these
impressed patterns lasted fairly well, but in the case of men's hats which are
more exposed to the weather such impressed patterns do not possess sufficient
durability.
According to the present invention, durable depressed patterns are produced on
felt hats or the like by means of a sand blast apparatus.
The process consists in placing the hat body which is to be treated on a suitable
block and covering it with a stencil plate of metal, vulcanite or other suitable
material, in which the pattern which is to be .produced is cut. The hat body thus
arranged is then exposed in a suitable machine to the action of a sand blast and is
moved to and fro in such a way that it is evenly operated on over its whole surface.
Depressed dull patterns are thus produced on the hat bodies. The hat bodies
decorated (or bearing designs) produced in this manner then undergo a further
treatment with smoothing irons and steam. Patterns produced by such a treatment
are naturally capable of withstanding the weather.
If the hats are intended to show a raised pattern on a dull ground, cement is
smeared through the template which is placed over the hat body, which cement
quickly drying is not affected by the sand blast and may be easily removed from
the hat after the treatment is completed.
A suitable machine for carrying out the process hereinbefore described will now
be described.
The hat bodies to be treated are placed over a wood block which is screwed on
the end of a rotating shaft. This shaft may oscillate to and fro like a pendulum.
on a shaft which is held or supported between fixed arms.
The oscillating movement of the shaft is produced by means of a crank wheel,
which is rotated from the driving shaft by means of suitable gearing. The crank
pin which is adjustably arranged in a radial slot of the crank wheel, imparts this
movement by means of a connecting rod to an arm of another shaft which is.
supported in the frame, the other end of which shaft carries an arm which is
provided with a slot. In this slot a pin is adjustably secured and is provided with
a slide-block which is free to reciprocate in a slot formed in an arm, which is
attached to the frame of the machine, this latter arm being. attached to another
shaft with which it may rotate. The frame carries at its upper end a shaft on
which a swinging frame is mounted, which latter in turn is pivotally connected to
a frame revoluble on the shaft which carries the shaft on which the oscillating
shaft swings, this oscillating shaft which carries the wood block and the hat body
being supported within the said frame.
By means of this apparatus the wood block with the hat body may be caused.
to oscillate to and fro over the sand blast apparatus, the extent of the oscillation
depending on the position of the crank pin and the pin, which is provided with the
slide block.

page_text: A rotary movement of the oscillating shaft is produced from the driving shaft
by means of chain gearing and bevel wheels.
Other materials such as cloth, felt articles and the like may also be provided
with depressed or raised patterns in the same way as hat bodies by a suitable
modification of the machine hereinbefore described.

An Improved Process and Apparatus for Producing Depressed or
Raised Patterns on Felt Hats, Felt, Cloth, or the like.
:
I, MAX WILKE of Gaben in the Empire of Germany, Hat Manufacturer, 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:
Repeated attempts have already been made to provide felt hats with depressed
or raised patterns, such patterns being produced by pressure.
In the case of women's hats which are generally protected from the rain, these
impressed patterns lasted fairly well, but in the case of men's hats which are
more exposed to the weather such impressed patterns do not possess sufficient
durability.
According to the present invention, durable depressed patterns are produced on
felt hats or the like by means of a sand blast apparatus.
The process consists in placing the hat body which is to be treated on a suitable
block and covering it with a stencil plate of metal, vulcanite or other suitable
material, in which the pattern which is to be produced is cut. The hat body thus
arranged is then exposed in a suitable machine to the action of a sand blast and is
moved to and from in such a way that it is evenly operated on over its whole surface.
Depressed dull patterns are thus produced on the hat bodies. The hat bodies
decorated (or bearing designs) produced in this manner then undergo a further
treatment with smoothing irons and steam exactly in the same way as with ordinary
felt bats. Patterns produced by such a treatment are naturally capable of with-
standing the weather.
If the hats are intended to show a raised pattern on a dull ground, cement
(which may consist of glue or dextrine, soluble in water, and sand) is smeared
through the stencil-plate which is placed over the hat body, which cement quickly
drying is not affected by the sand blast and may be easily removed from the hat
after the treatment is completed.
A suitable machine for carrying out the process hereinbefore described will now
be described reference being had to the accompanying drawings, in which :
-
Figure 1 is a side elevation of the machine;
Figure 2 a front elevation of the mechanism for operating the hat block and
Figure 3 a rear elevation of same.
The bat bodies to be treated are placed over a wood block T which is screwed
or the end of a rotating shaft S. This shaft S may oscillate to and fro like a
pendulum on a shaft A which is held or supported between fixed arms N.
The oscillating movement of the shaft S is produced by means of a crank
wheel M, which is rotated from the driving shaft K by means of suitable gearing.
The crank pin H which is adjustably arranged in a radial slot of the crank wheel
imparts this movement by means of a connecting rod to an arm i of another shaft E
which is supported in the frame, the other end of which shaft carries an arm W
which is provided with a slot. In this slot a pin F is adjustably secured and is

page_text: provided with a slide-block which is free to reciprocate in a slot for med in an
arm L which is attached to a frame P, this latter arm and frame being attached
to another shaft D upon which they may oscillate. The frame P carries at its
upper end a shaft G on which a swinging frame O is mounted, which latter in turn
is pivotally connected to a frame R revoluble on the shaft A on which the
uscillating shaft S swings, this oscillating shaft which carries the wood block T
and the hat body being thus supported within the said frame.
By means of this apparatus the wood block with the hat body may be caused to
oscillate to and fro over the sand blast apparatus, ✗ the extent of the oscillation
depending on the position of the crank pin H and the pin F which is provided with
the slide block.
A rotary movement of the oscillating shaft S is produced from the driving
shaft K by means of chain gearing z¹, and a which set in rotation the shaft B
which by means of bevel wheels bb imparts a rotary motion to the shaft S.
Other materials such as cloth, felt articles and the like may also be provided
with depressed or raised patterns in the same way as hat bodies by a suitable
modification of the machine herein before described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
1. An improved process for producing depressed or raised patterns on felt hats,
hat bodies, felt or cloth articles or the like, consisting in covering the articles or
material to be treated with a stencil plate cut to the pattern which is to be
produced or with cement by means of a stencil plate and then subjecting them to
the action of a sand blast apparatus, substantially as hereinbefore described.
2. An improved apparatus for use with a process such as described in Claim I
for the production of depressed or raised patterns on felt hats, hat bodies or the
like, comprising the combination with a sand blast apparatus of a shaft carrying a
block adapted to hold the article to be operated on, and means for imparting a
rotating and simultaneously an oscillating movement to the said shaft substantially
as described and illustrated.
