DOUBLE PRESSURE HYDRAULIC MACHINE
FOR HATS
Morris Schildhaus, New York, N. Y.
Application July 30, 1937, Serial No. 156,469
4 Claims.
This invention relates to new and useful im
provements in a double pressure hydraulic ma
chine for hats.
The invention has for an object the provision
in a pressure hydraulic machine for hats, of a
bottom forming section for supporting a hat hav
ing a crown portion and a brim portion, a top
forming section cooperative with the bottom form
ing section to shape the hat form, and a novel con
10 struction of the top section for applying differ
ent pressures to the crown and to the brim por
tions of the hat form.
ing I2 having an open bottom side and a central
projecting portion I28‘. The part IIb comprises
a ?exible crown forming element mounted on the
bottom of the projection He. The part I Ia com
prises a flexible brim forming element mounted
between the edge of said casing and on said pro
jection. The parts Hat and IIb are preferably
made of‘ rubber and may be formed either in one
or more pieces. A means is provided for supply
ing controlled hydraulic substance pressures to 10
said crown and brim forming elements.
The bottom forming section I0 is illustrated in
> Heretofore, it was customary to arrange the top
forming section with a single forming element
' which engaged the crown and the brim of a hat
and which applied equal pressure to these parts.
Experiments have shown that a better hat can
be produced if greater pressure is applied to the
crown than to the brim.
(Cl. 223—13)
The crown requires a
greater ‘pressure since it must be stretched and
formed to a greater degree. The brim requires
smaller pressures to keep the texture of the hat
material ?ne so that it feels good to the touch.
For further comprehension of the invention, and
of therobjects and advantages'thereof, reference
will be had to the following description and ac
companying drawings, and to the appended claims
in which the various novel features of the inven-‘
tion are more particularly set forth.
In the accompanying drawings forming a ma
terial part of this disclosure:Fig. 1 is a front elevational view of a double
pressure hydraulic machine for hats constructed
according to this invention.
Fig. 2 is a fragmentary plan view of Fig. 1.

Fig. 3 is a fragmentary transverse sectional
view taken on the center line of Fig. 2 but show
ing the piping for the hydraulic material, ap
plied schematically.
Fig. 4 is a fragmentary horizontal sectional view
taken on the line 4—4 of Fig. 3.
Fig. 5 is a fragmentary enlarged sectional view
taken on the line 5-5 of Fig. 4.
Fig. 6 is a horizontal sectional view taken on
the line 6——5 of Fig. 5.
Fig. '7 is an enlarged detailed view of a portion
of the bottom forming section shown in Fig. 3
but illustrated inverted.
The double pressure hydraulic machine for
50 hats, according to this invention, includes a bot
tom forming section I i! for supporting a hat hav
ing a crown portion and a brim portion, a top
forming section I I11, I lb cooperative therewith, and
means for forcing these sections together. The
55 said top section is associated with. a hollow cas
detail in Fig. '7 and.‘ consists of a rubber or simi
lar sheet material member I Be formed in the
shape of a hat having a crown and brim portion,
and covering sheets of felt material Nib-and 500
upon the outer and inner faces thereof. The felt
sheet It]0 extends over the brim portion of the
member we. The felt sheet Illa extends over
the crown portion only.
The bottom forming section I0 is rested on a
support element It having a rubber covered top
and inner portion l3a. This element I3 is re
movably mounted upon a support member I4. It
is held in correct relative position by pegs I5 co
operative between these parts. The support mem
ber I4 is supported on a carriage I6 which is pro
vided with wheels ll operating upon tracks I8
to
mounted on a body portion I9 of the machine.
The carriage I6 is provided with a handle 20 by
which it may be drawn forward and moved rear
ward, as required.
The top forming section I2 is slidably supported
upon the pair of vertical rods 22. More speci?cal
ly, the said casing I2 has bearing portions Ii.’c
slidably engage the rods 22. The rods 22 extend
upwards and support a stationary head portion
23. Between this head portion and the casing [2
there are a pair of spaced arms 24a, 24'“. Each
pair of arms comprise separate links, the said
parts 24a and 24*’ respectively, which are pivot
ally connected at their adjacent ends and at their
outer ends are pivotally mounted respectively on
the head 23 and the casing I2. One of the arms
24b is provided with a handle 26 by which the
arm 2410 may be moved to cause the casing !2
to move upwards and downwards.
.
The casing I2 is counter-balanced by cables 27
connected with the casing and extending upwards
over pulley elements 28. The free ends of the 50
cables 21 are provided with a counter-weight 29.
The ?exible crown and brim forming elements
are connected in a particular manner with the
projection IZe. The connection comprises a tube
30 engaging through the casing I2 coaxial with
2,110,739
2
the projection I28. A nut 3i is threadedly mount
ed on the tube 30 and acts against the top of the
casing 12. Another nut 32 is threadedly mounted
on the lower end of the tube 30. This latter nut
clamps an edge portion l l(1 formed on the upper
edge of the crown forming element H‘’. A re
silient washer or disc-shaped element 34 is inter
posed between the ?ange portion ! Id and the pro
jection He. The brim forming element HE and
10 crown forming element lib are integral with the
?ange portion | id (see Fig. 5).
A means is provided for supplying separate con
trolled hydraulic pressures to the crown and brim
forming elements. This means essentially com
prises a hydraulic substance system including a
15
supply tank 36 from which there extends a sup
ply pipe 31. This pipe is controlled with a valve
38 and connects with a pair of branch pipes 39
and 40. The pipe 39 is controlled with a valve
20 4| while the pipe 40 is controlled with a valve 42.
The pipe 39 connects with the tube 30 and with
a discharge pipe 3%. A hand release pressure
valve 43 is interposed in the pipe system 39.
The pipe 46 connects with a nipple 45 discharg
25 ing into the hollow of the casing i2, and further
connects with a discharge pipe 46 in which there
is interposed a hand controlled relief valve 41.
Pressure gauges ‘l8 and :59 are respectively
mounted upon the tube 30 and nipple 45. These
pressure gauges are adapted to show the pressure
within the crown forming element IIb and brim
forming element Ila.
By proper manipulation of the pressure valves
4| and t2 it is possible to build up the desired
35 high pressures in the crown forming element ! lb,
and the desired lower pressures on the brim
forming element He.
The operation of the device is similar to pres
sure hydraulic substance machines generally
known prior to this speci?cation. It distinguishes
in the operation of the machine, by obtaining
different pressures for the crown and the brim.
A further feature of the invention resides in the
speci?c construction of the brim forming ele
45 ment He and the crown forming element H”
and the manner in which these parts are sup
ported.
While I have illustrated and described the pre
ferred embodiments of my invention, it is to be
50 understood that I do not limit myself to the
precise constructions herein disclosed and the
right is reserved to all changes and modi?cations
coming within the scope of the invention. as de
fined in the appended claims.
