LEWIS FAIRBURN MARSH of Castle Green Bristol in the county of Gloucester
Hat Manufacturer and JAMES CREE of the Belgrave Iron Works, Denton near
Manchester in the county of Lancaster. IMPROVEMENTS IN APPARATUS FOR
PARING THE BRIMS OF SILK AND FELT HATS AFTER BEING CURLED AND SET
"

»
The object of this invention is to cut or trim the edges of hat brims mechanically
after the brims have been curled and set by hand or by a hat curling and setting
machine preferably of the kind patented by John Robinson Kelsey on the seventh
day of July 1881 N° 2991
According to our present invention we construct by casting or otherwise a head
plate on an upright and also an arm projecting under said head. The head carries
an adjustable gauge plate with a turned in lip on which the brim can rest and
serve also as the stock for resisting the pressure against the action of a knife
forming part of or attached to an eccentric or guillotine pivotted to a lug projecting
from the head the knife being moved by a cam bowl on the end of a shaft whose
opposite end has the band pulley by which it can be driven in any convenient
manner. The head also carries a bracket in a slot of which the pin of a feeding
tool can move during the upward and forward motions under the action of an
eccentric or cam also on the shaft the downward and backward motions being
governed by a spring.

page_text: The arm supports a pivotted balanced lever which is adjustable by a set screw
to determine the position of a curved face plate against which the hat brim presses
during the cutting operation. The curved face plate is jointed at about its centre
so as to be set at the desired angle by screw pins which pass through the wings of
a T piece whose leg is slotted and capable of sliding under the action of the
balanced weight to keep the brim to the knife and yet free to be drawn back by a
lever when the brim has to be inserted or withdrawn.
The curved face plate has a springy steel strip attached to its central part and
the ends are free but can be set to any size of hat by screws.
We purpose fitting a shaped dish with a ring plate arched and fitted under the 1
brim to serve as a guide for the knife to determine the width of the curl lip.

LEWIS FAIRBURN MARSH of Castle Green Bristol in the county of Gloucester
Hat Manufacturer and JAMES CREE of the Belgrave Iron Works Denton near
Manchester in the county of Lancaster IMPROVEMENTS IN APPARATUS FOR
PARING THE BRIMS OF SILK AND FELT HATS AFTER BEING CURLED AND SET"
The object of this invention is to cut or trim the edges of hat brims mechanically
after the brims have been curled and set by hand or by a hat curling and setting
machine preferably of the kind patented by John Robinson Kelsey on the seventh
day of July 1881 N° 2991.
The invention is clearly shown in the annexed drawings in which Figure 1 is
an elevation Figure 2 a front and Figure 3 a perspective view of the cutting and
feed appliances.
According to our invention we construct by casting or otherwise a head plate A
on an upright B and also an arm 0 projecting under said head. The head carries
an adjustable gauge plate D with a turned in lip E on or against which the brim
of a hat can rest said lip serving also as the stock for resisting the pressure against
the action of a guillotine knife F forming part of or attached to a plate G pivotted
at H to a lug projecting from the head A the knife being moved by a cam I on the
end of a shaft J whose opposite end has the band pulley K by which it can be
driven in any convenient manner. The head A also carries a bracket L in a slot
of which the pin of a feeding tool M can move during the upward and forward
motions under the action of an eccentric or cam N also on the shaft J the down-
ward and backward motions being governed by a spring P.
The arm C supports a pivotted balance lever Q which is adjustable by a set
screw R to determine the position of a curved face plate S against which the hat
brim presses during the cutting operation. The curved face plate Figure 4 can
be set at the desired angle by screw pins U, U, or pinch nut V which pass through
the slotted wing W and capable of sliding under the action of the balanced
weight X and yet free to be drawn back by the lever Q when the brim has to be
inserted or withdrawn.
The curved face plate S has springy steel or other strips Y, Y, so that although
the ends S¹, S¹, are set they can yield to suit any size of hat the brim of which is
placed upon the spring pillar Z. Figures 4a 5 and 6 are views of a modified
arrangement of plate S with jointed wings S¹ S' as end pieces. These are attached
by links Y Y to the adjustable slotted wing piece W.
We employ a shaped dish (Figures 7, 8 and 9) with a ring plate a arched into
which the hat whose brim has to be trimmed is arranged said ring bearing against
the guide or curved face plate S, S¹ to determine the breadth of the brim lip or
the cut therein.
Two clips cc (controlled by a spring d) can be arranged to hold the brim in
position during the cutting operation
In some cases the feed M can be dispensed with (the hat being fed and moved
round by hand) as can also the balance lever Q and balance weight X.
Having now described the nature of our said invention and in what manner the
same is to be performed We declare that We claim.
First The apparatus shown in the annexed drawings acting as above described
for cutting the edges of silk and felt hat brims after said brims are curleḍ
and set.

page_text: Secondly The combination of knife F and feed M set as arranged and operated
by distinct cams I, N on the same shaft as and for the purpose set forth.
Thirdly The turned in lip E of the brim supporting plate D as and for the purpose
described.
Fourthly The combination of weighted lover Q and winged adjustable plate SS' {
as and for the purposes set forth.
Fifthly We claim The shaped dish with ring plate (Figures 7, 8 and 9) for the
reception of the hat as a gauge or guide to determine the cutting
operation at the proper width of the curl lip as set forth
In witness whereof I the said Lewis Fairburn Marsh for myself and on behalf 1
of the said James Cree have hereunto set my hand and seal this sixteenth day
of October in the year of our Lord One thousand eight hundred and eighty three
