PROVISIONAL SPECIFICATION.
Improvements in Hat Sewing Machines.
I, EDMOND GREGORY O'DONNELL, of Fall River, in the County of Bristol and
State of Massachusetts, United States of America, Inventor, do hereby declare
the nature of this invention to be as follows:
-
It has hitherto been the practice to secure the sweat band to stiff felt and other
hats by hand sewing owing to the difficulty of reaching under the brim to the
base of the crown at which point the sweat band is sewed and the object of my
invention is to provide a machine for the purpose. To this end I construct a
sewing machine with a frame comprising an upper arm and a lower arm, the
former carrying the needle and presser foot and the latter the work and also
the stitch-forming devices. The needle and presser foot bars are provided with
arms projected inwardly to the end of the lower arm, and carry the needle and
presser foot so as to hold the same under the brim of the hat, and cause them to
work at the very base of the crown.
Both arms are integral with the frame of the machine and the upper arm pro-
jects outward beyond the end of the lower arm and carries the driving shaft
whose crank is provided with a link having axially elongated bearings for reduc-
ing the lateral movement of the link which is connected with the needle bar and
reciprocates the same. The presser foot bar is also mounted in the outer end
of the upper arm and extends parallel with the needle bar.
The lower arm carries a gauge for guiding the sweat band and is equipped with
a chain-stitch hook and the feed mechanism. The needle bar is provided with an
inwardly projecting and downwardly inclined arm, said arm extending to a
point just over the outer end of the lower arm and carrying the needle. With this
arrangement a very short needle may be employed, which is essential, seeing
that the needle must work beneath the brim of the hat. The presser foot bar
is provided with an arm extended inward alongside the arm on the needle bar
but inclined downwardly to a greater extent, said arm carrying the presser foot
which extends laterally to the arm and longitudinally with the brim of the hat,
so as to contact the inner edge of the presser foot with the brim of the hat, whereby
to guide the movement of the hat over the arm. The presser foot is cut away to
provide a space through which the needle may work.
In using the machine, the hat and the sweat band are placed over the lower
arm, the needle and presser foot bars being first raised to permit the passage
of the brim of the hat under the needle and presser foot, so that the sides of
the crown of the hat may bear on the arm, and the brim stand upward from the
arm inward of the bars. This causes the needle and presser foot to be projected
well under the brim to the base of the crown, and enables the sweat band to be
sewed in place.

I, EDMOND GREGORY O'DONNELL, of Fall River, in the County of Bristol and
State of Massachusetts, United States of America, Inventor, 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:-
It has hitherto been the practice to secure the sweat band to stiff felt and other
hats having a roll brim by hand sewing owing to the difficulty of reaching under
the brim to the base of the crown at which point the sweat band is sewed and
the object of my invention is provide a machine for the purpose.
To this end I
construct a sewing machine with a frame comprising an upper arm and a lower
arm, the former carrying. the needle and presser foot and being projected out
beyond the latter or lower arm, which serves to carry the work and also the
stitch-forming devices. The needle and presser foot bars are provided with arms
projected inwardly to the end of the lower arm, and carry the needle and presser
foot so as to hold the same under the brim of the hat, and cause them to work
at the very base of the crown.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding
parts in all the views.
Figure 1 is a side elevation of the invention with parts broken away; Figure 2
is a sectional plan on the line 2-2 of Figure 1; Figure 3 is a front elevation of
the invention, with the crown of the hat in section on the line 3-3 of Figure 1,
and Figure 4 is a detail sectional view taken through the lower arm of the
machine and showing the needle and complementary stitch-forming mechanism.
The frame A of the machine has an upper arm C and a lower arm B, the former
of which projects outward beyond the end of the arm B, and carries the driving
haft on which is fastened a crank C. To the crank C is connected a link D,
having axially elongated bearings 11 for reducing the lateral movement of the
link. This link is connected with the needle bar E, to reciprocate the
same. A presser foot bar F is also mounted in the outer end of the arm C and
extends parallel with the needle bar E.
The lower arm B carries a gauge for guiding the sweat band indicated by the
letter h. The lower arm B is equipped with a chain-stitch hook I and feed
mechanism G, as shown. The needle bar E carries an arm E which is projected
inwardly and inclined downwardly to a point just over the outer end of the
arm B, the arm El carrying the needle e. With this arrangement a very short
needle is employed, which is essential, seeing that the needle must work beneath
the brim H' of the hat. The presser foot bar F carries an arm F¹ extended inward
alongside the arm E but inclined downwardly to an extent greater than the
inclination of the arm E. This arm carries a presser foot f, which extends
laterally to the arm and longitudinally with the brim of the hat, so as to contact
the inner edge of the presser foot with the brim of the hat, whereby to guide the
movement of the hat over the arm B. The presser foot f is cut away as shown, to
provide a space through which the needle e may work.
In using the invention the hat H and the sweat band h are placed over the
arm B of the frame of the machine, the bars E and F being first raised to permit
the passage of the brim of the hat under the needle and presser foot, so that the
sides of the crown of the hat may bear on the arm B, and the brim stand upward
from the arm inward of the bars E and F. This causes the needle and presser
foot to be projected well under the brim to the base of the crown, and enables the
sweat band to be sewed in place as illustrated in the drawings.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
The arrangement of the parts E' and F' out of the line of the needle and
presser bars to enable the sweat band of the hat to be sewed in place.
