page_text: We JOSEPH CALVERLEY, of 195 Kingston Villa, Peckham Rye, London, Engineer,
and JOHN GIBBONS WHITEHEAD, of Dial House, Newton Moor, in the County of
Chester, Card Manufacturer, do hereby declare the nature of the said invention to be
as follows:-
Our invention consists in combinations and arrangements of mechanism for
expanding or stretching hats in two directions.
According to one modification of our invention two segments are used for the
lengthway and two for the breadthway each segment having a screw to screw into
a central ring, and each screw can be adjusted separately-There are or may be
projections or guides between each segment to keep them in the same plane.
According to another modification of our invention, the two opposite segments
have each one screw and screw nut between them.
The screw may revolve and the nut remain stationary or vice versa.
+
In the latter arrangement one fixed screw for two segments passes clear through
a slot in the rod on which the screw is formed for the other two segments.
The boss of one segment of each pair is arranged to grasp a collar on the
rotating screw nut but so as to allow it to revolve freely, by which arrangement
the segment and screw nut will move endways together.
In another modification of our invention each pair of segments is or may be
actuated by one right and left handed screw the screws being in different planes to
the extent required to pass each other.

page_text: We JOSEPH CALVERLEY of 195 Kingston Villa Peckham Rye, London, Engineer
and JOHN GIBBONS WHITEHEAD of Dial House, Newton Moor, in the County of
Chester, Card Manufacturer 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:-
Our invention consists in combinations and arrangements of mechanism for
expanding or stretching hats in two directions.
According to one modification of our invention two segments are used for the
lengthway and two for the breadth way each segment having a screw to screw into
a central ring, and each screw can be adjusted separately-There are or may be
projections or guides between each segment to keep them in the same plane.
According to another modification of our invention, the two opposite segments
have each one screw and screw nut between them.
The screw may revolve and the nut remain stationary or vice versa.
In the latter arrangement one fixed screw for two segments passes clear through
a slot in the rod on which the screw is formed for the other two segments.
The boss of one segment of each pair is arranged to grasp a collar on the
rotating screw nut but so as to allow it to revolve freely by which arrangement
the segment and screw nut will move endways together.
In another modification of our invention each pair of segments is or may 'be
actuated by one right and left handed screw the screws being in different planes to
the extent required to pass each other.
Fig. 1 is a plan view and fig. 2 is a vertical section and elevation illustrating one
modification of our invention.
The parts are shown in the drawing in the position they occupy when the
segments are drawn in, to suit the smallest size of ĥat.
In this modification the segments are supposed to be formed of wood or other
similar material.
a are the segments for the front and back or lengthway of the hat, and a' are
the segments for the sides or width way of the hat.
bare thin plates screwed on to the front and back segments to come upon the edge
of the brim near the inside of the hat and sustain the expander when placed loosely
within the hat.
To each segment a and a¹ there is a boss c attached by screws screwing through
the flange of the boss.
In each boss c one end of a screw d is arranged to rotate freely being kept in
the hole for it in the boss c by a screw screwing through the side of the boss c the
point of which screw enters a groove formed round the end of the screw.
Or in place of a screw, a pin is or may be inserted through a hole from one side
of the boss to the other, but in such position on one side that the side of the pin c¹
(see left side of figs. 1 and 2) will come within the groove formed round the screw.

page_text: There is a pin d¹ in a boss d³ for rotating each screw d which screws through a
hole in a central ring e.
By rotating the screws d one way the segments a or a¹ as the case may be are
forced outwards and by rotating the screws the reverse way the segments are
drawn inward.
To keep the segments a and a' in the same plane and prevent them from
rotating they are or may be connected together by four sets of thin plates as
shown Each pair of plates f is jointed together at one end (f¹) and each leg of
each pair of plates is secured and jointed to the segments by screws f' as shown.
When the segments a and a¹ are expanded the jointed plates f open to permit
them to extend and move apart while keeping them in the same plane and they
close again as shown in fig. 1, when the segments are again drawn together.
Fig. 3 is a plan view corresponding to fig. 1 and fig. 4 is a sectional elevation
corresponding to fig. 2 illustrating another modification of our invention where a
right and left handed screw is used for each pair of segments.
a and a¹ are the segments.
Each segment has a boss c attached to it by screws and each boss fits and slides
freely through a hole in a boss formed on a ring 9 which comes close to the inside
of the segments when drawn nearest together as shown.
Each boss has or may have one or two ribs or keys o' in its lengthway (two
are shown) which pass through corresponding grooves in the boss for it in the
ring g. This prevents the segments a and a¹ from rotating and keeps them in the
same plane.
Instead of keys con each boss c there is or may be a key groove the lengthway
of each boss c and a corresponding key in the boss in the ring g to fit the key
groove.
Each boss c is screw tapped to fit a screw spindle d which extends from the
boss c on one side to that on the opposite side-this spindle d having a right
handed screw thread at one end and a left handed screw thread at the other end
to fit corresponding screw threads in the bosses c.
One screw spindle d crosses and passes above and clear of the other as shown
and each is rotated by a pin or wheel d³ as desired and the two opposite segments
acted upon are thus simultaneously pushed outwards or drawn inwards.
Figs. 5 and 6 are views corresponding respectively to figs. 1 and 2 but illustrate
another modification of our invention where the segments are formed of elastic
metal.
In fig. 5 the segments a and a¹ are shown in full line drawn inwards to their
smallest size, and the dotted lines show their position when extended to their
largest size.
There are four segments each of which is secured by rivets a* (see fig. 6) to a
flanged boss c.
The flange of the bosses for the segments at the front and back have projec-
tions 6 having the same purpose as the plates 6 shown in figs. 1 and 2, and figs. 3
and 4..
There are right and left handed screw spindles din this modification as described
in reference to figs. 3 and 4.
Each end of each segment a bas a thin elastic piece of metal a³ rivetted to it and
each piece of metal a³ has a slot a¹ in it for a button a³ rivetted into the ends of
the segments a¹.
By this means the ends of the segments a and a¹ are united together, they are
also kept in the same plane and when the segments a are forced outwards their
ends a act upon the ends of the segments a¹ to force them outwards and bend
them to the shape of the larger sized hat.
The screw spindles d pass across each other one above the other and have
bearings in a bracket shown detached by fig. 7 a plan fig. 8 an end view on one
side and fig. 9 an end view on the other side,

page_text: On each spindle d a pulley or boss d is secured by which the spindle dis
rotated.
The pulley or boss d is or may be made with pins & or other projections
from it.
The boss of the pulley d' at one side comes against one end of the bracket h in
which a gap (h) is formed to fit a collar h* secured upon the screw spindle d.
This collar h prevents end movement in the screw spindle d and keeps one
screw spindle for one pair of segments (a) square to and in connection with the
screw spindle for the other pair of segments (a¹).
This bracket h has two arms h³ each of which is indexed for a pointer h* one for
the length the other for the breadth way of the hat which pointers are adjustable
and are each secured to one of the bosses c as shown in figs. 5 and 6.
The screw threads of the spindles d being right and left handed, the pointer h
only receives the movement produced by one screw but as it is arranged that both
screws shall be of the same pitch the index is formed to show how far the segments
(from outside to outside) are extended apart from each other.
The screws in each modification may be of any desired pitch, but for quick action
which is to be preferred they may be of coarse pitch and having two three or more
threads to each round or pitch.
Having now 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. The combinations and arrangements of mechanism for expanding bats in two
directions substantially as hereinbefore described and illustrated by the drawings.
2. The combinations and arrangements of mechanism for expanding hats in two
directions, and for measuring the size of hats substantially as herein before described
and illustrated by the drawings.
