Improvements in Hat Pouncing Machines.
We, ALBERT TURNER and ARNOLD TURNER, both of Turner Street, Ashton Road,
Denton, Manchester, Hatters' Machinists, do hereby declare the nature of our
said invention to be as follows:-
"3
This invention relates to a machine for pouncing the crowns of felt hats, and
has for its object to produce simple and effective mechanism which will impart to
the pouncing pad or pouncer a circular, elliptical, reciprocating or other surface
movement while pressed up elastically or yieldingly to the surface of the hat
crown. Other novel features of the invention reside in the mechanism for im-
parting the proper motion to the hat under the pouncer, and for automatically
withdrawing the pouncer from contact, and arresting the motion of the machine
when the pouncing operation is completed.
The machine comprises in general an upright hollow frame or pedestal on which
is mounted a "head," which rotates slowly through about a quarter-revolution on
a vertical axis during the pouncing operation, and is then unlocked and rotated
back again. This head carries the hat-block, which rotates more rapidly about
a horizontal axis. The pouncing pad is carried by an arm, through which a (by
preference) circular or elliptical motion is imparted to the pad, the latter being

pedestal is of cast iron, and comprises a hollow base and a hollow, column rising
from it. On the top of this column is a hollow "head" with tubular bearing
is a block shaft
extending into the top of the column, and within this "head
and block carrier.
"
By a shaft within the column, and suitable gearing driven from the main driving
shaft within the base of the machine, said block shaft and block carrier, and with
them the hat to be treated, are given a rapid rotation. By means of a hollow shaft
surrounding the shaft aforesaid within the column, a set of differential wheels
or "sun-and-planet" motion driven from the main shaft aforesaid, and a notched
or bolt under the action of a
disc or wheel, with the teeth of which a "dog
spring is caused to engage,-the "head" is given a slow rotative movement around
the top of the column.
"
Upon a supplementary, or side, shaft driven by spur wheels or chain gearing
from the main. shaft is a face cam or crank, to which is fitted a movable crank
pin. Pivotally connected to this pin is the bifucated extremity of the pouncer
arm, which extends upwards to a point opposite the hat block, and at which
point is provided with a pouncing pad, or strip of sand-paper held "bow-string
fashion between two adjustable fastenings made to swivel axially.
"
Surrounding the said arm, and pivoted to the machine frame is a swing frame,
which carries a sliding block, against which the pouncer arm rests, and which

page_text: follows the movements of the arm. To the end of the said swing
frame a lever or adjustable arm on one end of a (by preference) conical spring is
connected, or the extremity of a cord running over a pulley with weight attached,
and the tension of such spring or cord is such as to give an elastic support to the
pouncer arm. By having a cam or form plate attached to the block carrier head,"
and arranged between such "head" and the conical spring carrier, the latter may
slide against the plate, and being held against it by a stronger spring than the
conical spring, the same pressure of pouncer is obtained upon the entire surface
of the hat crown, the cam being made to the shape or form which the block or hat
assumes whilst traversing in the horizontal plane.
In using the machine the hat is first put upon the hat block. The pawl or
dog" engaging with the notched disc is then drawn out of engagement with the
disc, and by means of a suitable handle the "head" is rotated a quarter of a revolu-
tion, or until the pouncing pad comes on to the side of the hat crown, when the
pawl is allowed again to engage with the disc. In the operation of
turning back the "head" a stud engages with mechanism for shifting the driving
belt off the loose on to the fast pulley, which then imparts motion to the "head
block shaft and pouncer, and by means of a toggle" holding such mechanism
in play. The "head" is slowly rotated back to its original position, the block is
rapidly rotated on its axis, and the pouncer is given a rapid movement
upon the surface of the hat against which it is yieldingly held by the aforesaid
spiral spring.
<6
When the "head" has reached, or nearly reached, its first position, a pendant
or lever on the frame is caused to engage with the frame surrounding the pouncer
arm, push such frame away, and cause the pad to lie clear of the hat.
Immediately afterwards, or simultaneously, a stud on the head trips the "toggle,"
permits the belt to be moved back on to the loose pulley, and so stops the machine.
The hat block is held to the block axis by a clutch like device, consisting of a
set of claws or arms, caused to grip a conical or recessed boss or nipple of the hat
block under the contracting influence of a plate, screw or tightening sleeve.
The sand-paper is (by preference) drawn from a roll carried by the arm, and is
suspended over a pad of india-rubber or other elastic or pliable substance.
In the before mentioned arrangement of mechanism the hat or hat block has
two movements, i.e. one a circular rotative movement about its own axis, and the
other a horizontal movement due to the movement of the "head."
According to a modification of our invention we may impart an elliptical move-
ment to the hat or hat block in lieu of, or in addition to, the rotative circular
movement, since a hat body being elliptic or oval in cross-section, it is desirable
that the centre of rotation shall be moved to-and-fro during the rotation towards,
and away from the "pouncer" in order to avoid any variable pressure of the pad
on the hat, which would otherwise take place owing to the elliptical form of the
hat crown.
For imparting such elliptical or oval movement to the block we employ a
differential, or "sun-and-planet." motion to the block axis, which causes the axis
to move in an oval path, or we employ a set of levers and links and pivot the
"head" aforesaid to the part which drives it, and upon a fixed bracket secure one
of the said levers, by which, and by means of an eccentric sheave or cam on the
wheel which rotates the hat block, the hat is given an oval rotative motion, and
its centre caused to approach and recede from the pouncer, and so maintain an
even degree of contact for the entire surface of the hat body.

We, ALBERT TURNER and ARNOLD TURNER, both of Turner Street, Ashton Road,
Denton, Manchester, Hatters' Machinists, 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 relates to a machine for pouncing the crowns of felt hats, and
has for its object to produce simple and effective mechanisin which will impart to
the pouncing pad or pouncer" a circular, elliptical, reciprocating or other surface
movement while pressed up elastically or yieldingly to the surface of the hat
Other novel features of the invention reside in the mechanism for im-
parting the proper motion to the hat under the pouncer, and for automatically
withdrawing the pouncer from contact, and arresting the motion of the machine
when the pouncing operation is completed. The invention also comprises means
for giving the hat an elliptical movement so as to enable the pouncer to press upon
the hat with an equal pressure at all points of its surface.
On the accompanying sheets of drawings which illustrate an embodiment of
the invention, Fig. 1 is a sectional side elevation of the left-hand side of the
machine, the plane of the section being axial; and Fig. 2 is a front elevation of
the machine as seen from the right in Fig. 1. Fig. 3 is a plan of the machine.
These are general views; Figs. 1 and 2 show the parts in the position they
occupy at the completion of a pouncing operation when the machine has been
stopped by the shifting of the belt, and Fig. 3 shows the parts in the position
they occupy at the moment of beginning the pouncing operation.
Figs. 4 to 10 are detail views of important parts.
Fig. 11 is an elevation similar to Fig. 1, but shewing a modification in the
hat block traversing movement.
Figs. 12 and 13 represent enlarged front and side elevations of the said hat
block traversing movement.
Fig. 14 illustrates the pouncer pad as used with such machine.
"
"
Referring to Figs. 1, 2 and 3, (1) represents the frame or pedestal of the
machine, comprising a hollow base and hollow column and on the top of which
rests the hollow head (2). This "head" has for a bearing in the top of the
column a tubular journal (3) of considerable length on the head, extending down
into the top of the column.
In the base of the pedestal is the driving shaft (4) on which are mounted fast
and loose pulleys.
Keyed on the shaft (4) is a bevil pinion (5) which gears with a bevil wheel (6)
on an upright shaft (7). Through these wheels the shaft (7) is driven. On the
upper end of the shaft (7) is fixed a toothed wheel (S) which drives an upright
shaft (9) within the "head" (2) through the medium of a toothed wheel (10).
On the upper end of the shaft (9) is a bevil pinion (11) which gears with a bevil
wheel or toothed ring (12) fixed to the block-carrier (13).
Through this gearing the upright shaft (7) which is concentric with the bearing
This carrier
of the "head" (2) drives the block-carrier and block (14) thereon.
is rotatively mounted on a horizontal axis in the elevated part of the head (2),
and is provided with any suitable form of chuck to secure the block therein.
In the column of the pedestal is an upright hollow shaft (15) which encloses
the shaft (7), and is concentric therewith. At its upper end this hollow shaft
carries a locking disc (16) (see Fig. 6) in which are teeth, serrations or notches,
and on a handle (17) fixed to the head (2) (for turning said "head" back after

page_text: "
each pouncing operation) is a spring-dog (18) adapted to be pressed into locking
engagement with the teeth, serration or notches in the disc (16) by its spring.
This "dog" is furnished with a thumb-lever (19) whereby the operator grasping
the handle (17) may at the same time press the thumb-lever and withdraw the
dog" from engagement with the disc (16) and by such means the operator can,
at will, lock the shaft (15) to the head"
(2) and so permit the shaft (15) to turn
the "head" and unlock it again so that the "head may be turned back again
to the starting point without turning the shaft (15) back. This mechanism is
best seen in Fig. 6.
<6
66
At its lower end, the hollow shaft (15) carries a toothed wheel (20) with which
gears a
planet" pinion (21) rotatively mounted on an upright stud on the bevil
wheel (6). Just above the wheel (20) is another toothed wheel (22) fixed to the
pedestal and also in gear with the pinion (21). The wheel (22) has one tooth
more than the wheel (20).
As the bevil wheel (6) rotates, the pinion (21) rolls around the fixed wheel (22)
and thus advances the wheel (20) one tooth at each revolution of the wheel (6).
Thus a very slow motion is imparted to the shaft (15) relatively to that imparted
to the shaft (7).
We will now describe the pouncing devices. A counter-shaft (23) is mounted
in bearings in, or about, the pedestal and is driven from the main shaft (4) through
small and large gear-wheels (24) whereby such counter-shaft (23) is rapidly
rotated. On the end of this shaft is a crank-disc (25) on which is a crank-pin (26).
On this pin a block (27) is mounted and pivotally coupled to this block is a
'yoke" (28) on the lower end of an arm (29) which carries the pouncing pad,
indicated as a whole by (30) in Fig. 1.
$6
In order to impart to said pad an elliptical or circular motion through the
arm (29), means are employed which will now be described with special reference
to Figs. 1, 2 and 5. A swing-frame (31) is hinged at its lower end to a bracket (32)
on the column of the pedestal and embraces the arm (29). This frame has two
side-plates or limbs and between the upper ends of said limbs a rocker (34) is
pivoted at its ends on pivots (35). On the face of this rocker, next to the machine,
is mounted a guide-block (36) for the arm (29), which said guide-block is secured
to a journal (37) having a bearing in the rocker (34) at right-angles to the pivotal
axis of said rocker. In the face of the guide-block is a dove-tail groove to
receive a wearing plate (38) fixed to the arm (29). The upper end of the
frame (31) is coupled by a rod or link (39) to an arm (40) (Figs. 1 and 3) fixed
adjustably on the upper extremity of a shaft or spindle (41) which has bearings
in a conical bracket-casing (42) on the column of the pedestal (1). Within the
bracket casing (42) is a conical spiral spring (43), one extremity of which is
fixed to the bracket casing and the other, or upper, end to the shaft (41). This
spring, by its torsional resiliency, tends to draw the pouncing pad against the
hat on the block (14). The conical form of the spring is important as it serves
to steady the spring and equalize its action whilst a spiral spring of uniform
diameter becomes distorted under the strain.
"
To regulate the tension of the spring (43) the arm (40) is mounted to swing
radially on the shaft (41), and is provided with pawl or dog" (44) (see Fig. 3)
which engages teeth on a fragmentary ratchet disc (45) fixed on said shaft (41).
This is merely one form of tension-regulating device and other forms may be
substituted. The disc (45) may be a complete circular disc.
The arm (29) will be made (by preference) of hard wood as it should be light,
strong and stiff. On its upper end it carries the pouncing pad (30) best illustrated
in Figs. 1, 9 and 10. On the upper extremity of the arm (29) is secured a metal
hook (46) to support the upper end of the pad, and on the said arm, below this
upper hook, is mounted, in an adjustable manner, a hook (47) to support the
lower end of the pad. This pad comprises two like end plates (48) and a.flexible
strip (49) composed (by preference) of a backing of leather faced with soft vul-

page_text: canised rubber. This strip is secured at its ends to the plates (48) and these are
adapted to be engaged with the respective hooks (46) and (47).
A strip of sand-paper suitable for pouncing is applied to the face of the pad
and preferably in the following manner. In each end-piece or plate (48) is a
transverse slot (Figs. 9 and 10) and in the end-plate occupying said slot is a
clamping cam-roller (50) having a thumb-piece (51) at its end for operating it,
and a flattened face (52) (Fig. 9). The strip of sand-paper (53) is mounted on a
reel or spool (54) on the lower hook (47) and its end is carried through the slot
in the upper end-plate, down over the face of the strip (49) and back through the
slot in the lower end plate, as seen in Fig. 1.
The slots are opened to allow the strip of sand-paper to pass by bringing the
flattened faces on the clamping rollers around to the clamping margins of
the respective slots. When the paper is in place the rollers (50) are turned to the
position seen in Fig. 9, so as to cause the roller to clamp the paper fast. Tho
paper may be readily shifted when the part which overlies the strip (49) becomes
worn out.
As before stated, the parts occupy the position seen in Fig. 1 when the pouncing
operation is completed, the pounced hat being still on the block (14). During the
last portion of the slowly rotating movement of the "head" a pusher (55)
mounted on the "head" (preferably in an adjustable manner) presses against a
swinging lever (56) on the column of the pedestal and causes the free end of the
lever to impinge on the frame (31) and swing it back to the position seen in
Fig. 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 pendant projection (57) on the
head (2) (see Fig. 7) trips a "toggle" and allows a spring-actuated belt-shifter (58)
to shift the belt (59) to the loose pulley (60) thereby stopping the machine. This
device may now be described.
65
The shifter (58) is in the nature of a forked arm fixed on a rock-shaft (61)
(see Figs. 1 and 3) mounted in suitable bearings on the machine frame. Attached
to an arm (62) on this shaft is a strong spring (63) which tends to rock the
shaft (61) so as to cause the shifter to shift the belt to the loose pulley. The
arm (62) is coupled by a link (64) to the shorter arm of an elbow-lever (65) ful-
crumed on the column 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 setting
stud or projection (66) on the latter (Fig. 7) which when the head" is set to
the starting position seen in Fig. 3, swings the lever (65) over and by means of
the link (64) and arm (62) shifts the belt (59) to the tight pulley (67). The
lever (65) is held in the position set by a toggle" device, comprising an elbow-
link (68) (see Figs. 7 and 8) fulcrumed on a bracket (69) on the column of pedes-
tal (1), and another link (70) connecting the link (68) to the lever (65). Whilst
this "toggle" is straight, its knuckle is slightly depressed and supported on a
pin (71) on the bracket, and the lever (65) is prevented moving; but when the
pouncing operation is nearly completed the pendant stud (57) before mentioned
breaks the knuckle of the " toggle" upward through the medium of a horizontally
mounted lever (72) fulcrumed on the upper face of the supporting bracket (69)
and clearly shown in Fig. 8. The stud (57) impinges obliquely on an elevated
part of the lever (72) and in passing said part causes the end of the lever to
strike the now upright arm of the elbow-link (68), so as to rock the same and
break the toggle. When this is done the spring (63) instantly shifts the belt (59)
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 attaches the
block to the block carrier, then places the hat to be pounced upon the block, or
in some case the operator detaches the block (14) from the block-carrier (13)
removes the pounced hat therefrom, places a hat to be pounced on the block and
again secures the block on the carrier. He now grasps the handle (17) with his

page_text: right hand, and holding back the pouncing pad with the other hand presses his
thumb on the lever (19) and thus withdraws the "dog" (18) from engagement
with the teeth on the disc (16). He then turns the "head" (2) around to the
position seen in Fig. 3, lets the pouncing pad on to the crown of the hat close to
the brim, which is the point of starting and then permits the dog" (18) to
again engage the teeth of the disc (16). In the operation of turning back the
head" the belt (59) will be shifted to the tight pulley (67) through the means
already described, that is, the engagement of the setting stud (66) with the upper
end of the lever (65) and the machine is thus set in motion; the "head" (2) turns
slowly around in the direction of arrow (X) in Fig. 3 whilst the block and hat
revolve much more rapidly in the direction of the arrows (Y) in Figs. 1 and 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 form, but its form may
vary according to the proportions of the parts as will be understood by anyone
skilled in the art. The extent of movement or length of travel of the pad may
be varied by shifting the crank-pin (26) which operates the arm (29) in the slot
in the face of the crank-disc (25) which carries the pin. This adjustment of the
crank-pin is a common device and will need no explanation. It will be noted
that the pad does not 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 centre of the hat crown comes under the pouncing pad, the pusher (55)
strikes the lever (56) and swings the pad away from the hat a moment before the
stud (57) trips the "toggle" and permits the spring (63) to shift the belt on to
the loose pulley. This brings the parts of the machine back again to the position
seen in Fig. 1. The hat is then removed from the block.
If desired the hat may be subjected to a second pouncing operation before it
is removed from the block.
The device for clamping the hat block (14) to the block-holder (13) as shewn
in Figs. 1 and 4 will now be described.
33
In the elevated part (2*) of the "head (2) is a large bearing in which the
hollow journal (73) of the holder is rotatively mounted. The ring gear (12) is
secured to the circular face-plate of the holder, and the latter has, or may have a
thin metal flange (13*) to form a guide and support for the hat brim. A crank (74)
has a boss (75), which screws into the open outer end of the hollow journal (73) of
the holder, and this boss also screws in the manner of a nut, on a screw-threaded
spindle (76) in the axis of the journal (73). This spindle extends through the
face-plate of the holder which is provided (see Fig. 4) with a guide plate (77), in
which the spindle (76) is fixed so that it may not rotate except with the holder (13).
The guide-plate (77) has also apertures in which are guided three jaws (78), the
inner ends of which are loosely coupled to a flange (79) on the spindle (76). The
block (14) has a central bore to fit over the projecting end of the spindle, and this
bore is formed in a nipple on the block which is grasped by the jaws (78). By
turning the crank (74) in the proper direction, the spindle is drawn outward,
carrying with it the jaws (78), and the inclines on the backs of these jaws cause
them to clamp onto the nipple of the block and hold it firmly up to the face-plate
of the holder. The exterior screw-thread on the boss of the crank or hand wheel
is left-handed and the interior thread right-handed; consequently the clamping
effect is produced with a very moderate movement of the crank, or hand wheel.
It will be noted that the particular characteristics of this machine are as
follows: The hat is rotated under the pad about the axis of its crown, and
simultaneously and more slowly about an axis at right angles to its axis and
substantially elliptical at the top in a cross-section taken along its axis, it follows
that the pad must yield as the hat revolves under it. As the surfaces over which
the pad passes are all convex the flexible character of the strip forming the pad
enables the latter to adapt itself to these surfaces. The pad itself moves in a
closed or endless curved path, and this may be elliptical, ovoid or circular. In the
construction shewn the crank-pin (26) carries the lower end of the arm (29) about

page_text: a circular path and as this arm has a sliding fulcrum about the journal (37), it
follows that the pad carried on the upper end of the arm (29) will when the crank-
disc (25) rotates, traverse a closed, curved path the form and lateral dimensions
of which will be governed by the position the journal (37) occupies between the
crank-disc (25) and the pad. As the pad always receives an up-and-down move-
ment equal to the throw of the crank-pin (26) and the lateral movement of the
pad will be varied according to the position of the fulcrum point along the
arm (29), it follows that if the said point is nearer to the pad than to the crank-
disc, the path followed by the pad will produce an ovoid figure. Preferably this
figure will be so small as to be included within the width of the pad.
"
By "crown is here meant the entire body of the hat above the brim. Where
the hat is quite flat on top and the curve where this top joins the side of the
crown is quite sharp or abrupt, the attendant may ease the pouncing pad over
such curve if this be considered necessary.
In the before mentioned arrangement of mechanism the hat or hat block has
two movements, i.e., one a circular rotative movement about its own axis, and
the other a horizontal movement due to the movement of the head.
According to a modification of our invention we may impart an elliptical move-
ment to the hat or hat block in lieu of or in addition to the rotative circular move-
ment, since a hat body being elliptic or oval in cross-section, it is desirable that
the centre of rotation shall be moved to-and-fro during the rotation towards and
away from the "pouncer" in order to avoid any variable pressure of the pad on
the hat which would otherwise take place owing to the elliptical form of the hat
crown.
In Figs. 11, 12 and 13 we shew one form of apparatus for effecting such elliptical
movement of the hat. We will first describe Fig. 11 which is a view similar to
Fig. 1 except in the upper part, and Figs. 12 and 13 which are enlarged views
of such upper part for the better explanation of our invention.
On the upper end of the shaft (7) is fixed a bevel wheel (80) which gears with
a bevel pinion (81) fixed on a counter-shaft (82) mounted in bearings in the
"head" (2) at right angles to the shaft (7). On the shaft (82) is fixed a gear-
wheel (83) which gears with a similar wheel (84) of twice its size, fixed on the
shaft (85) which carries the hat, and which is rotatively mounted in a bearing
piece (86) mounted loosely on the shaft (82) at its foot, and adapted to swing
or oscillate about the axis of said shaft (82) as a centre. The shaft (85) is sub-
stantially parallel with the shaft (82) and the oscillation of the bearing piece (86)
does not disturb the intermeshing of the teeth on the wheels (83) and (84).
On the "head" (2) is a suitable bracket (87) to which is secured a fulcrumed
arm (88) and to the outer end of this arm is coupled a longitudinally slotted
lever (89) by means of a fulcrum bolt (90), the construction being such that the
lever may be fulcrumed on the arm (88) at any point along the slot.
An arm
or connecting rod (91) is coupled at and to the upper arm of the lever (89) and
in the other end it has an eye which loosely embraces the boss of the wheel (84).
Another connecting rod (92) is coupled at one end to the lower arm of the lever (89)
and in the other end has an eye which embraces an eccentric (93). formed on the
boss of the wheel (83).
The effect of the above described mechanism is to rotate the shaft (85) and
at the same time impart to it, through the eccentric (93) rocking lever (89), and
rods (91) and (92) a motion toward and from the pouncing pad, this oscillation
being effected twice during each rotation of the hat.
The extent of this oscillation may be varied at will by loosening the fulcrum
bolt (90) and moving the lever (89) up or down in order to vary the length of its
arms and the construction enables this to be done quickly and conveniently with-
out disturbing or dismantling the machine. Indeed it is feasible to do it while the
machine-is in operation.
Of course it will be understood that the forming of the eccentric (93) integral

page_text: with the boss of the wheel (83) the mounting of the bearing-piece (86) directly
on the counter-shaft (82) and other minor details of the construction, are merely
matters of choice and need not be strictly followed in carrying the invention into
practise.
In order that the pouncing pad may adjust itself the better to the surface of
the hat, especially in passing about an abrupt curve where the side of the hat
crown joins the top thereof, the pad is swivelled in the line of its longitudinal
axis as will now be described.
The pad (30) is made, by preference, of rubber and faced with felt or other
suitable material on which is laid fine sand paper suitable for pouncing. The
pad proper is provided with metal end-pieces (94) to which it is removably
secured by a screw and thumb-nut (95) so that it may be readily removed and
replaced. On each end-piece (94) in line with the longitudinal axis of the pad,
is a collared journal (96) which finds a bearing in a suitable pad support (97)
on the arm (29). The journal (96) permits the pad to turn freely about its
longitudinal axis when the exigencies of the case as stated above require it to
do so.
To avoid marking the hat in the pouncing, it is desirable the pad shall
be free to adapt itself to the surface to be pounced at all times.
In this modification the hinged frame (31) is coupled to a lever (98) fulcrumed
on the pedestal behind the toggle and the upper end of said lever (98) has a
pin (99) which engages with the lever (65). Fig. 13 shews the position of the
parts at the moment before the knuckle of the toggle is broken upward, when this
takes place the quick movement of the upper end of lever (65) swings the lever (98)
over and pushes the frame (31) back. For nicety of adjustment the end lever (65)
may be provided with adjusting set screw (33).
In lieu of imparting a circular motion to the pouncer, we may impart a recipro-
cating up and down movement only by employing a fixed slipper block (36) and
provide the arm (29) with a knuckle joint, or link' forked end to the disc (25).
It will also be obvious that the pad might be stationary and the pouncing be
effected by the movement of the hat but the operation would be slow, and in such,
or other like cases the pad may be held at right angles to the arm (29), and with
slight variation of gear and supports the movement imparted to the head (2) by
gear wheels ( ) may be at vertical instead of horizontal. It is also conceivable
that the head (2) may be arranged to remain stationary and the pedestal and
base, and with them the arm (29) travel round the head, but we prefer the former
arrangement.
