Improvements in Machines for Paring the Curls of Hat Brims.
I, THOMAS GARE, of 25, Booth Street, Edgeley, Stockport, in the County of
Chester, Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a machine which will pare the curls of
hat brims to any desired shape more reliable, regularly and quickly than heretofore
has been the case.
One end
To this end I employ in suitable bearings a shaft adapted to rotate.
of this shaft, say the upper end I furnish with a block or frame adapted to tilt
when required and to receive the hat to be pared. Upon the lower end of the said
shaft I secure a pinion adapted to gear into another pinion preferably of half the
diameter secured to the lower end of another shaft mounted in a frame the lower
end of which is hinged to the bearing in which rotates the first named shaft at a
point near the said pinions. The upper end of the said frame is furnished with an
arm the free end of which is adapted to engage and run in or along the angle of
the curl of the hat brim and to form a guide in the paring of the curl.
The upper end of the said shaft is furnished with a cam or eccentric adapted to
reciprocate on the said arm a bar carrying at its free end a knife blade the point
of which is guided in a slot formed in the part of the aforesaid arm or guide which
runs in or along the angle of the curl of the hat brim.
In lieu of reciprocating the said knife bar it may be arranged stationary on the
said frame and the said guide reciprocated by the said cam or eccentric.
In lieu of the knife blade described a pair of scissors may be employed one
blade of which is actuated by such as a crank pin and flexible shaft.
The free end of the said arm or guide may be shaped to engage and run along
either the inner or outer side of the angle of the curl or both as may be found
most convenient.
The cam or eccentric aforesaid serves to move the knife or guide (as the case
may be) gradually from and to the angle of the curl so as to cause the said knife
or scissors to pare the curl in width and shape in accordance with the eccentricity
the cam or eccentric possesses.
It will thus be readily understood that by changing the cam or eccentrics the
curl may be pared to any width and shape.
The brim of the hat is adapted to rotate over a support positioned below the free
end of the said arm or guide.
The frame for the support of the hat to be pared consists of a number of spring
strips fixed to a plate in an oval fashion so as to be wider in circumference at the
top than at the bottom, a spring hoop being attached to their upper ends to bind
the same together.
By means of an oval hoop placed around the said frame its upper end can be
contracted to allow of placing the hat thereon and when withdrawn allow the frame
to expand and securely hold the hat.

I, THOMAS GARE, of 25, Booth Street, Edgeley, Stockport, in the County of
Chester, Engineer, 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 :-
The object of my invention is to provide a machine which will pare the curls of
hat brims to any desired shape more reliable, regularly and quickly than heretofore
has been the case.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet. of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a side view, Fig. 2 an end view and Fig. 3 a plan of a complete machine
constructed in accordance with my invention.
Fig. 1 is a sectional side view at an enlarged scale, of the back end of the guide
arm and knife bar.
Figs. 4, 5 & 6, are respectively a longitudinal section, an end view and a plan,
and Figs. 9 & 10 a sectional side and an end view of a modification of the paring
knife and its adjacent parts.
Fig. 7 is a side view of the guide which engages the hat brim curl,
Fig. 8 a sectional side view of the back end of the respective arm and
knife bar,
Fig. 11 a sectional side view of the hat brim curl guide showing some modifi-
cations of the same.
e,
mounted
Referring to Figs. 1, 2 & 3, I employ on the frame a, a¹ of the machine, in
suitable bearings a², a², a short shaft b suitably rotated, say by a worm wheel c,
secured to its lower end and in gear with a worm d secured upon a shaft
on the frame a in bearings a³, a3 and rotated by a strap and pulley f, f¹, respectively,
and clutch operated by a foot lever f³, which permits of rotating the shaft bone
revolution at the time. The upper end of the shaft b I furnish with a block or a
specially constructed frame g, as hereinafter described, upon which the hat to be
pared is placed and which is adapted to tilt when required and by the means
aloresaid rotated intermittently. In order to obtain the said tilting action, by
preference I connect the block or frame g to the shaft b by means of a flexible
shaft b. Upon the shaft b, I secure also a bevel wheel / adapted to gear into a
pinion preferably half the diameter of the bevel wheel h and secured to the
lower end of another shaft i mounted in bearings k, k, formed on a frame k¹³,
the
lower end of which is hinged to the bearing or frame part a¹.
The upper end of the frame k¹ is supported laterally in an arm at forming part
of the frame a and has an arm hinged thereto the free end of which is furnished
with a hook like bit adapted to engage in the angle of the curl m of the hat brim
and to serve as a guide in the paring of the curl.
Near the free end, the arm is supported between two centres carried by the
arm a which allows the guide bit and corresponding part of the arm to fall and
rise in accordance with the shape of the hat brim curl to be pared.
The upper end of the shaft i is furnished with a cam or eccentric m', see Fig. 1*,
adapted to reciprocate, on the arm l, a bar n carrying at its front end directly or
indirectly a knife blade o, see also Figs. 4, 5 & 6, which is adapted to pare the hat
brim curl to the required shape and the point or cutting edge of which enters a
slot p formed in a support p' fixed directly or indirectly to the knife bar n upon
which support the hat brim curl moves, a spring 9 being fixed to the knife bar n
which bears against the upper surface of the hat brim curl and holds the same

page_text: down upon the said support, the spring 9 having also a slot q' for the passage of
the knife o. By preference I reciprocate the paring knife o, by fixing it to a
rod n¹ suitably guided in a bracket n² fixed to the knife bar n and under the
influence of a spring n³ which presses a projection n formed on the rod n' against
a cam r fixed upon a shaft r¹ mounted upon the knife bar n.
Rotary motion is imparted to the shaft r from the driving shaft e by means of a
cord suitably guided and the pulleys ³,
In lieu of reciprocating the knife bar n it may be arranged stationary and the
guide bar reciprocated by the cam or eccentric m¹, for instance as shown in
Fig. 8.
In lieu of employing only one knife blade o, two may be employed scissor like,
as shown in Figs. 9 & 10, o being movable as previously described and o¹ fixed to
the hat brim curl support pl.
The cam or eccentric m³ aforesaid serves to move the knife o or guide 7 (as the
case may be) gradually from and to the angle of the curl so as to cause the knife o
or scissors o, o¹, to pare the curl in width and shape in accordance with the shape
and size of the cam or eccentric.
It will thus be readily understood that by changing the cam or eccentric m¹ in
size and shape the curl may be pared to any width and shape.
In addition to the guide bit 1, a guide
influence of a spring 13 upon the guide arm
side of the angle of the hat brim curl, as
found most convenient, or the guide bit
guide piece employed only, as shown in
rendered stationary on the guide arm l.
piece 12 may be employed under the
and adapted to bear against the outer
shown in Figs. 1 to 7, and as may be
may be dispensed with and the outer
Fig. 11, in which case the latter is
The frame g, see Figs. 1 & 2, for the support of the hat to be pared consists of
a number of spring strips t fixed to a plate u in an oval fashion, so as to be wider in
circumference at the top than at the bottom, an open or split spring hoop v being
attached to their upper ends to bind the same together.
By means of an oval hoop w placed around the said frame its upper end can be
contracted to allow of placing the hat thereon and when withdrawn allow the frame
to expand and securely hold the hat.
In lieu of rotating the hat frame or support g as described, it may be rotated
intermittently by hand or the same may be stationary and the paring arrangement.
adapted to move around the hat as will be readily understood.
I am aware that, hat brim curl paring machines with rotary hat support and
movable knife have been used but in such machines the shape of the hat brim curl
is obtained by a guide or former plate arranged to rotate with the hat to be pared
or with its support, against a fixed point.
In my invention I dispense with the said guide or former plate, by longitudinally
reciprocating, the paring knife or the guide arm which carries it relative to the
angle of the hat brim curl, by means of a rotary cam or eccentric which defines
the size and shape of the hat brim curl to which it is to be pared.
It will thus be readily seen that my method of defining and obtaining the shape
of the hat brim curl, is superior to that referred to as it renders the machine much
simpler in construction, more reliable in action and easier to manipulate.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is
-
"In machines for paring the curls of hat brims."
1st. A hat support, in combination with an arm / having at its free end a guide /
or guides 1 & 2, adapted to engage the angle of the curl of the brim internally or
externally or both and to hold the same in position relatively to the knife which
cuts the curl, all substantially as set forth.
2nd. In combination with the guide arm 1, a bar n carrying a knife and
reciprocated longitudinally in relation to the angle of the hat brim curl, by a

page_text: rotating cam or eccentric m³, the size and shape of which defines the shape and
size to which the hat brim curl is to be pared all substantially as set forth.
3rd. As a means for supporting hats to be pared a support, consisting of a
number of spring strips t, the lower ends of which are secured to a base u and the
upper ends tight together by a flexible ring v in connection with a sliding ring wo
adapted to contract the said spring strips and release the hat, all substantially as
set forth.
