rod 21 and stroke-adjusting rod'3l, and also
has a chamber or bore 32a in which is disposed
suitable packing 34 and a plug bearing 35 for pis
ton rod 21. A piston is slidably received in
cylinder 9 and is secured to piston rod 21 in any
nected to various control valves whereby ?uid
under pressure is directed to one“ or the other of
, two hydraulically actuated pistons._ Thus, in.
Figure 1, a lower piston, generally indicated at 1
and mounted on column 5, isactuated to rotate
an assembly, generally indicated at- 8, whereby
10 pouncing tool 2 mounted thereupon travels about
hat block I in an axis substantially perpendicular
to the axis of rotation of the hat block. An up-'
. per piston, generally indicated at 9 (Figures 1 and
4) and mounted on the head of the machine, is
actuated by the ?uid under pressure from the oil
suitable manner.
'
~
As viewed in Figure 4, piston 33 is at its ex
treme right hand position and accordingly a port
36 communicates with the interior of cylinder‘ 9
behind piston 33 while a‘port 31 and a port 38
communicate with the interior of cylinder 9 in
pump to impart axial movement to spindle 3,
this movement, however, preferably not being
imparted to spindle 3 until the movement of tool
2 about hat block I has ceased, all as will be more
w front of piston 33. The operation and purposes 20
of these ports in relation to piston 9 will be more
20 fully described hereinafter.
Referring now to Figures 1 and 4, hat block I
is secured to spindle 3 by means of a suitable . fully described hereinafter.
From the above it may now be seen that as

generally indicated at II. Clutch II is comprised
of a driving member I2 and a driven member I3,
therebetween provided by'bracket 26 and piston
member I3 being slidably related to spindle 3 and
having a driving relation therewith by means of
suitable keys or splines. Driving member I2 is
30 secured to a clutch sleeve I4, journaled in a hous
ing I5, a part of the head bracket, and is driven
by' a pulley I6 which is suitably secured to clutch
rod 21. One of the several advantages of pro
viding an axially movable hat block lies in the
fact that considerable versatility accrues to the 30
machine in that hat bodies of varied dimensions
and shapes may be accommodated. Further
more, by providing the threaded connection be
sleeve I4, pulley I6 being driven by- motor 4 by
tween piston rod 21 and bracket 26, whereby axial
adjustment of spindle 3 may be-attained by the
manual rotation of knob 29, it is possible to posi
tion hatblock I (Figure 1) in relation to pounc~
means of a suitable belt I1 (Figure 1).
Clutch II (Figure 4) is thrown into and out of
engagement by means of a clutch fork I8 mounted
on a clutch shift rod I9 slidably received in the
\ head bracket and shiftable by means of a clutch
lever 29. As is more clearly shown in Figure 5,
40 shift rod I9 has associated therewith a detent 2I
adapted to maintain the clutch in either its en
gaged or disengaged position. Clutch lever 20
is suitably secured to a pin 22 rotatably mounted
in a housing 23 which journals one end of spindle
ing tool 2 in such a manner that a hat body of ex
ceptional depth may be operated upon, thus ob
viating the necessity of providing additional ma
chines for hat bodies of varying depths.

Referring now to Figures 1 and 3, motor 4 is
preferably mounted in a housing portion 39 (Fig

equipped with suitable reduction gears 40 which

through a pipe 5| past a pressure'gauge 52 into
a metering valve 53, and from metering valve 53
by means of a pipe 54 the oil ?ows into a direc
tion-control valve 55.‘
As is more clearly shown in Figure 11, the
direction-control valve~55 is provided with an
3
"8,105,180
‘ inlet port 55a and an exhaust port 5511. Thus.
oil under pressure admitted into valve 55 through
inlet'port 55a ?ows out of valve 55 through a‘
port 56 when a direction-control plunger 51- is in
the full line‘ position shown in Figure 11. When
the plunger 51 is in this position, exhaust oil re
turns to the valve 55 through a port 58, passes
through a channel 59 within the valve and thence
out of the valve through an exhaust port 55b into
10
the end of its travel so that port as is completely
open to receive the full oil pressure.
As piston -
63 has ceased its~ travel, exhaust oil ceases to
?ow through pipe 18 and‘v oil under pressure
?owing through port 64 now ?ows through port
65, thence through pipe 1|. through port 36 of
the cylinder 9 and behind piston 33, thus forcing
piston 33 to the left as viewed in FigurelO. The
exhaust oil pursues substantially the same‘route

When plunger 51 is in the dotted line position

shown in Figure 11. However, plunger 51 is held shown in Figure 11, the oil ?ow, and consequently

'
The shaft of plunger 51, is also preferably pro
20 vided with a notch 510'. into which a spring
biased ball 62a of a detent 62 drops to hold valve
' opposite direction. Thus oil ?owing into valve 55
by way of inlet port 55a ?ows ‘out of the valve
through port 58 and into cylinder 9'by way of 26
pipe 69 and port 38-thus forcing piston 33 toward '

the ports 56 and 58 entirely, so that oil can ?ow a port 65 and pipe .68 and flows into valve 55 (Fig

51a and 51b slide.
The means and purposes’of
positioning plunger 51 as described above will
be. more fully pointed out hereinafter.
Referring to Figures 1 and 10, a lower piston
63 ~recip1‘ocates within cylinder 1 provided with
ports 64, 65 and 66, this piston and cylinder being
which in turn meshes with a‘driving gear 16
(Figure 9). Rack 14 is held inoperative rela

indicated at 18,, extending from the base 5a of 45

' to ports’36 and 31 ‘as pointed out hereinabove.
A pipe 68 ‘leads from port 56 in valve 55‘ to Rotatably mounted, preferably by ball bearings
6 port .64 in cylinder 1, and a pipe 69 permits
communication between port 58 of valve 55 (Fig
ures 10 and 11) and port 38 of cylinder 9. Cylw
inders 9 and 1 are in communication by means
of a :pipe .18 between ports 31 and 66 and by a
.60 pipe 1| between ports 36 and 65.‘ Thus, when
valve plunger 51 is in the full line position shown
83_and 84 orgthezlike, on shoulders 8i and 82 55
respectively, I provide a casting or the like, gen;
erally indicated at 85, and it is on a downwardly
extending portion 85a of this casting that the
teeth of drive gear 16 are cut.
Portions 85a. of
casting 85 has a bore 86 which’ communicates ’
with an exhaust conduit 81 secured to the bottom
in Figure 11, ?uid under pressure is free to ?ow of housing portion 80 for purposes to be herein
from port 56'through pipe 68 and into cylinder after pointed out. .

in Figures 1, 2 and 7, accordingly includes a sup 65
port 88 (Figure 7) and an upper chamber 89
"communicating with bore 86. Support 88 of cast
ing 85 has a projection 88a in which a bore 90
of cylinder 9 through port 38;‘ thence through is formed and this bore receives a pin 9| pref
erably secured against rotation as by a set screw 70

the pressure of thetool against the hat body

feed rate of the tool be decreased slightly in or
der that the line contact pointed out above does 45
not result in the formation of unsightly rings

proceeds from that‘portion of the cam designated
by the letter C in Figure 16 to that portion of
the cam designated by the letter A, in which po
sition the tool has been backed off a substantial
10 distance from the hat block. By referring to Fig
ure 14 and Figure 16, the relationship of tool‘ 2
to hat block I is illustratively shown, the letters
A, B, C, D and E, ‘which indicate the several
positions of tool 2 (see (Figure 14) being coinci
dent with the letters A, B, C, D and E, which
indicate the positions of roller I35 on cam I29
(Figure 16) which has effected the related posi
'15
tions of the tool.

Under certain circumstances it is desirable that
tool 2 be operated manually and backed off a
further distance from hat block I than results
from the ultimate progression of cam roller I35
to the top-mostpoint of cam I29. As pointed
out above, direction-control valve 55 (Figure 11)
25 has a neutral position.’ and when the valve is in
this position, swinging arm‘ 8 can be manually
‘ pivoted as the ?uid in the system is free to ?ow
in either direction. To maintain swinging arm 8
a distance further spaced from hat block I than
results from the normalloperation of the arm,
'I have provided a release ‘trigger I5I (Figure 2)
pivotally mounted on support bracket 981), A
lever I52 .pivotally mounted on arm 93a is con
nected at one end- to trigger I5I by a link I53.
The other end“ of lever I52 is connected to a
latch I54 by a rod I55; the lower end of latch
I54 (Figure '1) projecting normally below the
top edge of casting 35. Thus, when trigger I5I is
pivoted in a clockwise direction (Figure 2) lever
I52
pivoted in a counterclockwise direction,
causing a counterclockwise pivoting of latch I54
to place the latch into a position where ‘it may
engage the top of casting 85and thus hold the
swinging arm in an extended pivoted position in
45 a direction away from the hat block.
In order to effect the reverse feeds of the hat
block and tool as mentioned above, I have pref
erably provided both manually and automatically
'50
fected automatically. As hat block I approaches
the end of its forward feed stroke, the length
of which may be determined by the positioning
of an adjustable stroke-adjusting trip I64 which
is slidably mounted on stroke-adjusting rod 3|
(see Figure 4), trip I64 abuts a push rod I65
slidably mounted in the top of housing portion
39. As push rod I65 is forced to the left, as
viewed in Figure 4, it eventually abuts a lug I66
secured to reversing lever I59, thus forcing lever
I59 away from housing portion 39 and bringing
about the release of plunger 51 in.valve 55 to
effect a reversal of operations as pointed out
above with respect to the manual operation of
reversing lever I59.
‘
It is to be‘ noted that inasmuch as trip I64
can be positioned at any point on stroke-adjust
ing rod 3|, the length of the feed stroke of bat
block I 'may be vpositively determined or varied
according to the depth of the hat body being 20
operated upona Thus, a short stroke is obtained
by positioning trip I64 to the left in Figure 4
and a long stroke by positioning the trip to the
right.
'
'
'
Under certain conditions, asfor examplé where 25
very shallow hat bodies are being ?nished, it
is desirable ‘in the interests of economy of time
that the automatic reversal just described be
supplemented by a quicker acting mechanism
which effects a reversal of‘ the feed of tool 2 only 30
and suspends the hat block feed.
To this end, '
1 preferably provide a -valve trip hook I61 (Fig
ure 1) pivotally mounted in a bracket I68 secured
to piston rod 13. As is more clearly shown in
Figure 9, hook I61 may be swung from its opera
tive position shown in full line in Figure 9 to an
inoperative dotted line position and maintained
in either by means of a wing nut I69 or the like.
_Whcn hook I61 is in its operative position it 4
contacts a projection I1I'Ia (Figures 1 and 9) of 40
a bell crank lever generally indicated at I16
(Figure 1). When piston 63 has reached the
end of its stroke toward the right of cylinder 1
(it being noted that this stroke imparts initial
feed to tool 2), the abutment of hook I61 against
projection I10a causes‘bell crank lever I16 to
pivot about a stud "I (Figure 1) mounted in a
suitable boss formed on column 5. This pivoting

cured to column 5. When lever I59 is pivoted
away from column 5, end I60a of bell crank
cured to projection I1Ilb and slidably extends '
55 lever I60 raises an end 163a (see Figure 11)
through a guide I13 secured to column 5.
.As valve release rod I12 (Figure 11) is thus
raised it pivots bell crank lever I63, with the
result that plunger 51 is released to assume its
dotted line position as‘ shown in Figure 11, thus
rection-control valve 55. As end I63a (Figure
11) is raised the other end I63b of bell crank
60 lever I63 is withdrawn from its engagement
with shoulder 510 of valve ‘plunger 51 thus per

so'that gates 51a and 51b of the plunger assume
the dotted line positions shown in ‘Figure 11.
65 When in this position a reversal of the operations
takes place, that is,‘ piston 33 (Figure 10) ?rst is

To instigate the operation ‘of the machine, I
have provided a- valve operating lever I84 (Fig

in Figure 2, valve operating lever I84 has a lug 25

As valve operating lever I84 (Figure 1) is

and accordingly rack 14 completes its stroke.
Immediately upon the halting of piston '63 the
?uid pressure is shifted into upper cylinder 9
in back of- piston 33 therein to effect motion of
piston 33 from‘ the right to the left, as viewed
10 in Figure 1.‘ This movement of piston 33 is im
‘ parted to hat block spindle 3 and accordingly the
rotating hat body‘ is fed past the now stationary
pouncing
tool.
-
'
‘
When the hat body has reached- the end of its ‘
tion of the operating cycle will not ensue because
the fluid, instead of ?owing in the directions
indicated by the arrows in Figures _10 and 11, will
be ?owing in an opposite direction, and as the
pistons cannot 'travel any further in reverse UK
direction, the oil will by-pass through pressure
regulating valve 49 and thus return to the oil
reservoir in column 5 by way of pipe 59.
It will now be seen that I have provided a hat
?nishing ‘machine which will accommodate a hat 10
body of unusual depth. By providing cams which
automatically vary the pressure of pouncing tool
2 on the hat body and which vary the feed rate
of the tool at those portions of the hat body

have madeit possible to puta uniform ?nish on
the exterior surface of the hat body by remov
ing the same amount of felt therefrom at sub
against reverse lever push rod I65 which-slides
to the left causing reversing lever I59 to be
thrown. Asreversing lever I59 is thrown, bell
20 crank lever I60 pivots and one end thereof trips
bell crank lever I63 (Figure 11) to release the
engagement of arm I63b from shoulder 510. As
' this engagement is released, plunger 51 in direc
tion control valve 55 automatically shifts into a
reverse position under the bias of spring 60, and'
in this position the direction of flow of the ?uid
under pressure immediately shifts so that the
?uid now ?ows in a direction opposite to that in
dicatedby the arrows in Figure 10.

'
Now follows a sequence of- operations exactly
the reverse of those pointed out above until‘ the
pouncing tool returns to its original position or
‘position A shown in Figure 14.
During the forward and reverse feed strokes
of both the pouncing tool and the hat body, the
speed rate is varied for purposes hereinbefore set
forth. Thus, as rack ‘I4 moves from the left to
, the right in Figure 1, cam roller I‘I5 rides over
the surface of cam I'M which is carried by rack
40 ‘I4. As pointed out above, the different positions
indicated-on cam I14 in Figure 15 effect different
feed rates of the pouncing tool. Thus, upon the
forward stroke, the portions of cam I ‘I4 indicated

As has, been stated hereinabove, it is desirable
that the pressure of the pouncing tool upon the
hat body be constant and uniform throughout
the pouncing or ?nishing operation. It may
readily be seen that to obtain this'constant and
uniform tool pressure during the finishing oper 40
ation on a hat body of oval shape entails di?l
culties not encountered in finishing a hat body
of regular frusto-conical shape. As an oval hat
body has a multitude of different diameters the
surface of the hat body travels through an ex 45
tremely irregular path when the hat body is
rotated; that is, if a‘ tool were to be held sta

being substantially as already described. Thus
the main difference isin the head assembly and‘
the drive therefor, which will be more fully de
scribed hereinafter.‘
‘ ‘
'. “ Referring now to Figure 19,,’ wherein there is
15 shown on an“ enlarged‘ scalepasectional ‘eleva
tion of my oval head assembly, main shaft I88
is preferably 'journaled in ball bearings I93 and
I94 nrounted in housings I95 and I98 which are
‘preferably integral parts of head bracket I92.
20 Preferably, an end I88a of shaft ‘I88 is reduced
and on this end is secured a rear. support I9‘I
which conveniently takes the form of a drum.
Upon rear support or drumv I91 there is mounted
an upper pulley cap I98 which is held .in related

Accordingly, it will now be seen that there are
two axes of rotation‘, namely: one axis indicated
by the letter A (Figure 21) which is the axis of
rotation-of main shaft I 88 in addition to being
the axis of stationary pinion 203, and the axis
indicated by the letter B which is the axis of
rotation of internal gear 220 and accordingly
spindle 205. Thus, when rear support I91 and
pulley cap I98 and the‘ parts contained therein 15
are rotated by belt IT, a double rotation is im
parted to spindle 205 because of the connection
thereof ‘with pulley cap I98 bymeans of arm
2H and because of the meshing of internal gear
220 with stationary pinion 203. In ‘other words,
spindle 205 revolves about the axis A, the radius ‘
of ‘revolution being A_-B, and also spindle 205

As mentioned hereinbefore, journal 209 (Fig

?ange 2| I. Thus ?ange 2“ has integrally pro

Thus, when the pouncing tool is operating on
top of the hat, it is not so important to come 25
pensate for the different diameters of the oval
shape inasmuch as the eccentricity of rotation
during this period of the ?nishing operation will
not result in varying pressures, as the plane of
the surface of the top of the oval hat does not 30
change.
With further reference to Figures 18 and 23,
as rack ‘I4 moves to the left, pouncing tool 2 is
driven in forward feed direction, idler gear ‘I5 ac
