Improvements in Sewing Machines applicable for Binding the Brims
of Hats.
I, JOHN CASSELS, of 76, Hall Street, Stockport, in the County of Chester,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
In the sewing or stitching the binding on to the brims of hats the needle
enters from the outside of the curl and it is necessary to arrange the shuttle and
shuttle carrying mechanism to pass between the edge of the brim and the crown
or body of the hat without pressing or damaging the crown or body.
This invention consists essentially in arranging and combining the shuttle
or looper actuating or driving mechanism from the arm that carries or supports
the needle bar so that there is no bottom bar or plate projecting from the base
of the machine.
It may be applied to either transverse or longitudinal driving mechanism and
rotary reciprocating revolving rectilinear reciprocating or oscillating or vibrating
shuttles or loopers and the machine may be applied to any purpose for which it
may be found applicable.
In carrying out the invention an arm bar or bracket is carried down from
the arm of the machine beside the needle bar and provided at the lower end with
a small chamber to receive the shuttle. This is covered with a small plate or
cover through which the needle passes down to engage the shuttle thread. Pro-
jecting upwards for some distance practically vertically to sufficient distance to
be clear of the work is a small driving shaft or spindle through which motion
is transmitted to the shuttle either reciprocating or rotary. This is fitted at both
ends with toothed or friction wheels the bottom one engaging with the shuttle
carrier and the upper one with a rack or bevel wheel or driving device as
required.
In the case of single thread chain stitch machines a looper may be used
instead of the shuttle and be driven in a similar way.

Improvements in Sewing Machines applicable for Binding the Brims
of Hats.
I, JOHN CASSELS, of Hall Street, Stockport, in the County of Chester, Mechanical
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:-
In sewing or stitching the binding on to the brims of hats the needle
enters from the outside of the curl and it is necessary to arrange the shuttle and
shuttle carrying mechanism to pass between the edge of the brim and the crown
or body of the hat without pressing or damaging the crown or body.
This invention consists essentially in arranging and combining the shuttle
or looper actuating or driving mechanism with the arm that carries or supports
the needle bar without a bottom bar or plate projecting from the base of the
machine.
It will be fully described with reference to the accompanying drawings in
which sufficient of a sewing machine is shown to illustrate the invention.
Fig. 1 is a side elevation.
Fig. 2. is a side clevation (enlarged) of the extended arm of the machine with
the shuttle carrier and driving mechanism.
Fig. 3, is a side elevation of same in section on line z-z Fig. 7.
Fig. 4, is a front elevation of same in section on line y-y Fig. 7.
Fig. 5, is a plan partly in section on line - Fig. 2.
Fig. 6, is a plan partly in section on line ww Figs. 3 and 4.
Fig. 7, is a plan in section on line Figs. 3 and 4.
The arm A which carries the needle bar B is extended down beside and
beyond the needle bar and at its lower end is fitted or constructed a shuttle
box or carrier or chamber C to receive the shuttle D. Any plate or bar extending
from the base of the machine to carry the shuttle is dispensed with and a large
unobstructed space at E is provided into which the body or crown of the hat
can enter when under operation to permit of free access of the needle of the
machine to the brim of the hat and at all points whilst stitching on the binding.
The chamber C receives a shuttle 1 of suitable shape and construction and is
covered with a small plate or cover e through which the needle and top thread
passes down to engage the shuttle thread. The shuttle rests upon the disc F
attached to a small spur wheel f which is oscillated or rotated backwards and
forwards by a second pinion g mounted on the lower end of an upwardly pro-
jecting driving spindle or driving shaft G.
The small driving shaft or spindle G projects upwards for some distance
practically vertically to a sufficient height to be clear of the work. On the
upper end of the driving spindle G is fitted a second pinion H which engages a
rack K by which it is driven.
The rack K is carried at the end of a bent rod or lever L actuated by a cam.
attached to the driving or fly wheel M of the machine.
The pinion H and rack K are covered by a plate to prevent the thread
getting into the teeth.
The invention may be applied to transverse or longitudinal driving mechanism
and also to revolving or rectilineal reciprocating or oscillating shuttles or loopers
and the machine may be applied to any purpose for which it may be found
applicable.
For a continuous rotary movement the driving spindle is rotated by a wheel

driving mechanism.
In the case of single thread chain stitch machines a looper may be used
instead of the shuttle and be driven in a similar way.
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:
1. A sewing machine constructed with a shuttle and shuttle race carried at
the end of the extended arm and suitable driving mechanism without a base
plate or bar substantially as described.
2. In a sewing machine the combination with extended end of the arm A of
a shutter or shuttle box and upright driving spindle geared thereto extending
to a sufficient height above the shuttle to clear the work and an operating rack
operated by a suitable cam or mechanism substantially as described.
3. A sewing machine having the several parts constructed and arranged in
combination substantially as described and shown.
