Improvements in Apparatus for Pouncing Felt Hats.
We, HENRY HERBERT TURNER, ALBERT TURNER, and ARNOLD TURNER, all
of Turner Street, Ashton Road, Denton, Manchester, in the County of Lancaster,
Hatters' Machinists, do hereby declare the nature of our said invention to be
as follows:-
These improvements have reference to an invention for which Application for
Letters Patent No. 17190 was made on the 21st day of July 1897, and consist in
means for enabling the pressure of the pouncing pad to be fully applied on the
"up" stroke, and be relaxed (or removed) on the "down" stroke (or vice versa),
and so be adapted for pouncing hats "with" (instead of "against" the lay of
the felt. Our improvements also consist of novel mechanism for giving a
compound rotary movement to the hat whilst under treatment, in lieu of the
lever arrangement described in the Specification of the said former Patent, and
they (our improvements) also comprise modifications of details.
In accordance with the first part of our invention, we introduce an arrange-
ment of links or rods between the arm of the conical spring and the pouncing
arm carrier, in lieu of the continuous or rigid rod or cord heretofore used. Con-
nected to, or forming part of, one of said links is a rod, depending downwards
to a point in close proximity to the driving shaft of the machine, and the lower
end of said rod is connected to an eccentric on the said driving or like shaft,
which is so "timed" or
"set" in relation to the face cam for operating the
pouncer staff, that with each downward movement of the pouncer staff the said
rod moves upwards and straightens out the links, which were previously deflected,
and thus lengthens the distance between the said spring arm and the pouncer staff,
and thereby relieves the pressure of the pad on the hat.
66
To increase the extent of such relaxation, we may employ two or more rods,
and increase the number of links, with one or more eccentrics to operate the
same. Or the throw off" of the pad may be effected by the fulcrum of the
pouncer shaft being fixed, and the eccentric arranged to operate the lower end
in a to-and-fro direction.
In accordance with the second part of our invention, we carry the shaft
which rotates the hat block through a sleeve or hollow shaft, which in turn
revolves in the "head" of the machine. This latter (the sleeve) is concentric
with its bearing, but the shaft is eccentric to the sleeve, consequently when the
sleeve is rotated it carries the shaft bodily round a centre. Upon the end of the
shaft is an internal pinion which meshes with a fixed external pinion, and upon
the end of the sleeve is a bevil wheel, gearing with a small bevil pinion driven
from the mechanism, described in the said former specification, which rotates
the hat block.
By such bevil pinion the sleeve is rotated and thereby caused to gyrate the
shaft within it.
By reason of the external pinion on its end, and the fixed or stationary pinion
aforesaid on the casing, the shaft is caused to rotate on its own axis, and thus as

page_text: 68
the sleeve serves to carry the hat bodily towards, and away from, the pad the
shaft gives it the required rotary motion, and the two motions combined may be
appropriately called a sun and planet" motion, which with the major axis of
the hat set in proper relation to the throw of the sleeve, serves to make the
pressure of the pad more or less uniform on all parts of the hat, which would
otherwise be uneven owing to the oval shape of the hat.
In reference to the further feature of our invention we employ an arrange-
ment of chains and chain wheels, in lieu of the gear wheels aforesaid, and
mount the axis of the lay shaft in a bracket hinged to the base of the casing
containing the conical spring, and capable of radial adjustment to suit the
sizes of wheels, and to keep the chains taut.

We, HENRY HERBERT TURNER, ALBERT TURNER, and ARNOLD TURNER, all
of Turner Street, Denton, near 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:

"
These improvements have reference to an invention for which Letters Patent
No. 17190 were granted on the 21st day of July 1897, and consists in means for
enabling the pressure of the pouncing pad to be fully applied on the up stroke,
and be relaxed (or removed) on the down stroke (or vice-versa), and so be adapted
for pouncing hats with instead of against the lay of the felt. The
improvements also consist of novel mechanism for giving a compound rotary move-
ment to the hat whilst under treatment, in lieu of the lever arrangement described
in the Specification of the said l'atent, and of certain improvements in details.
On the accompanying drawing Fig. 1 illustrates a part side elevation of
the machine described in the said former Specification with our improved easing
motion shewn applied thereto. Figs. 2 and 3 illustrate a similar side elevation,
and a front view with a modification of the "casing" motion shewn applied
thereto, and the lower end of the pouncer staff broken away to shew the parts
more clearly. Fig. 4 illustrates a longitudinal section of the mechanisni for
imparting a compound rotary motion to the hat under treatment and attaching
the hat block to such mechanism.
Fig. 5 illustrates a front or end view of Fig. 4 with the hat block removed.
In accordance with our invention we introduce links (A), (B) between the
arm (C) of the conical spring contained within casing (1) and the pouncing
arm carrier (E), in lieu of the continuous and rigid rod heretofore used. Con-
nected to, or forming part of the links is a rod (F) which extends downwards
to a point in close proximity to the shaft (G), where it is coupled to the sleeve
of an eccentric (H) on the shaft (G). The throw of such eccentric is set in
such relation to the face cam (I) for operating the pouncer staff (J) that with
each upward movement of the pouncer staff the eccentric (H) pulls the rod (F)
downwards, and in consequence folds the links (A) and (B), or causes the

page_text: distance between the points of connection to be shortened. With each downward
movement of the pouncer staff the eccentric (H) raises the rod (F), and in con-
sequence straightens out the links, or causes the distance between the points of
connection to be lengthened. This shortening and lengthening has the effect of
varying the pressure of the pouncing pad on the hat under treatment.
To increase the extent of relaxation we may employ two or more rods,
and increase the number of links, with one or more eccentrics to operate them.
Or we may arrange for the "throw off" of the pad being effected by the fulcrum
of the pouncer staff being fixed, and the eccentric arranged to operate the
lower end in a to-and-fro direction.
In Figs. 2 and 3 we show how this is effected. The motion of the shaft (G)
is imparted to a lay shaft (K) by skew wheels (L) and the end of the pouncer
staff (J) is eccentrically connected to, and operated by the disc (M), which gives
the movement aforesaid to the pouncing staff. The fulcrum (E) of the pouncer
staff in this modification is fixed (or substantially fixed), i.e., the arms (E) are
stationary, and the rod or link (A) is simply used to help in supporting such
arms. The staff (J) slides up and down on the carrier slide (J) sustained
pivotally on the fulcrum (E).
In accordance with our further improvements and referring to Figs. 4 and 5,
we carry the shaft (N), which rotates the hat block (0), through a sleeve or
hollow shaft (P). This sleeve or shaft (P) is concentric with the head (Q) but
the shaft (N) is eccentric, consequently when the shaft (P) is rotated the
shaft (N) is carried bodily around the centre of the shaft (P). Upon the end of
the shaft (N) is an internal pinion or gear wheel (R) which meshes with a
fixed external pinion (S) and upon the end of the shaft (P) and concentric
therewith is a bevil wheel (T) gearing with a small bevil pinion (U) driven from
the mechanism described in the said former specification for rotating the hat
block. By means of the said bevil pinion (U) the bevil wheel (T) and the
shaft (P) are rotated and thereby caused to gyrate the shaft (N). By reason of
the internal pinion (R) on its end, and the fixed pinion (S) on the casing, the
shaft (N) is also caused to rotate about its own centre, and thus, as the shaft (P)
serves to gyrate the shaft (N) and the hat block on such shaft bodily, the shaft (N)
gives the hat block and hat a rotary motion about their centre, and with the
major diameter of the hat crown in a horizontal position when the shaft (N) is
at its furthest lateral position within the shaft (P) from the pouncing pad as
shewn by dotted lines in Fig. 5, the two rotary motions combined cause the
pressure of the pad to be equal at all points on the surface of the hat, which
might otherwise be variable owing to the oval shape of the hat.
For attaching the hat block to the shaft (N) we employ a scroll (V) upon the
face of hand-wheel (X), and a set of grips (W) hinged to and carried by
supports (W) fixed on the shaft (N). By the rotation of the hand-wheel the
grips (W), which engage with the scroll (V) as illustrated, are caused to grip
the nave of the hat block, and carry such block round with the shaft, or by a
reverse movement of the hand-wheel release the block.
In lieu of the spur gearing shewn and described in the said previous specification
for driving the shaft (G) we employ chain gearing, as shewn, and mount lay
shaft (Y) in a bracket (Z) hinged to the base of the casing (D), or other suitable
part, and capable of adjustment to suit the various sizes of wheels, and to keep the
chains taut.
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is:-
1 In felt hat crown pouncing machines of the kind described, the use and
combination therewith, of means for causing the pressure of the pouncing pad
upon the hat to be alternately diminished and increased, substantially as and

page_text: for the purposes herein set forth, and shewn in Figs. 1 to 3 of the accompanying
drawing.
2: In felt hat crown pouncing machines of the kind described, the combination
therewith of a swivelling head, a hollow concentric shaft within such head, a
shaft within and eccentric to such hollow shaft and head, bevil or mitre wheels
for driving the hollow shaft, and fixed and revolving gear wheels for driving the
eccentric shaft, substantially as and for the purposes set forth.
3: In felt hat crown pouncing machines of the kind described, the com-
bination therewith of chain driving wheels and chains, and a hinged bracket
to keep the chains taut, and allow for different sizes of wheels, as set forth.
