cause the roller to clamp the paper fast. The
paper may be readily shifted when the part
- which overlies the strip 37 becomes worn out.
As before stated, the parts occupy the po-
5 sition seen in Fig. 1 when the pouncing op-
eration is completed, the pounced hat H be-
ing still on the block 12. During the last
portion of the slowly-rotating movement of
the head a pusher 41, mounted on the head
to 2, (preferably in an adjustable manner,)
presses against a swinging lever 42 on the
column of the pedestal and causes the free
end of this lever to impinge on the frame 24
and swing it back to the position seen in Fig.
15 1, thus moving the pouncing-pad away from
and out of contact with the hat on the block.
At the same time another stud or pendent
projection 43 on the head 2 (see Figs. 5, 6,
and 7) trips a toggle and allows a spring-ac-
20 tuated belt-shifter 44 to shift the belt X to
the loose pulley 4X, thereby stopping the ma-
chine. This device may now be described.
The shifter 44 is in the nature of a forked
arm fixed on a rock-shaft 45, (see Figs. 1 and
25 3,) mounted in suitable bearings on the ma-
chine-frame. Attached to an arm 47 on this
shaft is a strong spring 46, which tends to
rock the shaft 45, so as to cause the shifter
to shift the belt to the loose pulley. The arm
30 47 is coupled by a link 48 to the shorter arm
of an elbow-lever 49, fulcrumed on the col-
umn of the pedestal 1. The longer upright
arm of this lever projects up nearly to the
base of the head 2 and is in the path of a set-
35 ting stud or projection 50 on the latter, Fig.
6, which when the head is set to the starting
position (seen in Fig. 3) swings the lever 49
over and by means of the link 48 and arm 47
shifts the belt X to the tight pulley 4. The
40 lever 49 is held in the position set by a toggle
device comprising an elbow-link 51, Figs. 6
and 7, fulcrumed on a bracket Sixon the col-
umn of pedestal 1, and another link 52, con-
necting the link 51 to the lever 49. While
45 this toggle is straight, its knuckle is slightly
depressed and supported on a pin on the
bracket and the lever 49 is held against move-
ment; but when the pouncing operation is
nearly completed the pendent stud 43, before
50 mentioned, breaks the knuckle of the toggle
upward through the medium of a horizontally-
mounted lever 53, fulcrumed on the upper
face of the supporting-bracket 51x and clearly
shown in Fig. 7. The stud 43 impinges ob-
55 liquely on an elevated part of the lever 53,
and in wiping by said part causes the end of
the lever to strike the now upright arm of the
elbow-link 51, so as to rock the same and
break the toggle. When this is done, the
6o spring 46 instantly shifts the belt X to the
loose pulley.
The operation of the machine is as follows:
Starting from the position of the parts seen
in Fig. 1, the operator detaches the block 12
65 from the block - carrier 1l, removes the
pounced hat therefrom, places a hat to be
pounced on the block, and again secures theblock on the carrier. He now grasps the han-
dle 15 with his right hand, and holding back
the pouncing-pad with the other hand presses 70
his thumb on the lever 17, and thus withdraws
the dog 16 from engagement with the teeth
on the disk 14. He then turns the head 2
around to the position seen in Fig. 3, lets the
pouncing-pad onto the crown of the hat close 75
to the brim, which is the point of starting,
and then permits the dog 16 to again engage
the teeth of the disk 14. In the operation of
turning back the head the belt X will be
shifted to the tight pulley 4 through the 8o
means already described-that is, the engage-
ment of the setting-stud 50 with the upper
end of the lever 49-and the machine is thus
set in motion, the head 2 turns slowly around
in the direction of arrow z in Fig. 3, the block 85
and hat revolve much more rapidly in the di-
rection of the arrow thereon in Fig. 3, and
the pouncing-pad moves rapidly in a closed
curved path over the surface of the hat. This
path in the present construction is of oval 90
form; but its form may vary according to the
proportions of the parts, as will be under-
stood by any one skilled in the art. The ex-
tent of movement or length of travel of the
pad may be varied by shifting the crank-pin 95
21a, which operates the arm 23, in the slot in
the face of the crank-disk 21', which carries
the pin. This adjustment of the crank-pin
is a common device and will need no explana-
tion. It will be noted that the pad does not too
rotate on its axis, but moves bodily in a closed
curved path or orbit. The head 2 makes a
little less than a quarter of a rotation, and
when the center of the hat-crown comes un-
der the pouncing-pad the pusher 41 strikes 1o5
the lever 42 and swings the pad away from
the hat a moment before the stud 43 trips the
toggle and permits the spring 46 to shift the
belt onto the loose pulley. This brings the
parts of the machine back again to the posi- io
tion seen in Fig. 1.
If desired, the hat may be subjected to a
second pouncing operation before it is re-
moved from the block.
The device for clamping the hat-block 12 to r i5
the block-holder 11, as shown in Figs. land 1,
will now be described. In the elevated part
2,1 of the head 2 is a large bearing in which the
hollow journal 11x of the holder is rotatively
mounted. The ring-gear 10 is secured to the 120
circular face-plate of the holder, and the lat-
ter has or may have a thin metal flange 11a
to form a guide and support for the hat-rim.
A crank 54 has a boss 54, which screws into
the open outer end of the hollow journal 11x 125
of the holder, and this boss also screws, in
the manner of a nut, on a screw-threaded
spindle 55 in the axis of the journal 11. This
spindle extends through the face-plate of the
holder, which is provided (see Fig. 1') with a 130
guide-plate 11", in which the spindle 55 is
splined, so that it may not rotate except with
the holder 11. The guide-plate 11 has also
apertures in which are guided three jaws 11,
