PROVISIONAL SPECIFICATION.
Improvements in and relating to Sewing Machines for Fringing the
Edges of Textile Fabrics.
We THOMAS BARKER, SAMUEL SNAPE and WILLIAM WILSON of the firm
of Barker Snape and Wilson of Phetheun Street Works Bolton in the County
of Lancaster, Machine Makers, do hereby declare the nature of this invention to be
as follows:-
We propose to dispense with the ordinary double ended connecting rod and
adjustable bracket which is usually secured to the slide carrying the looper, and
substitute a filbon which is at liberty to oscillate on a stud fixed in the ordinary
slot of swinging lever, and a connecting rod having at one end an eye placed on a
stud secured to slide carrying the looper. The other end passing through the
aforesaid filbon at right angles to the stud on which it oscillates. The connecting
rod having a screw thread for lock nuts to lock same in position in filbon, or in
some cases we propose to use a connecting rod without screw thread, and hold same
in position in filbon by a set screw.
In place of the ordinary looper which is now made in one piece, with a boss near
its centre which fits on stud in siide for looper to oscillate upon, we propose to
apply a projection on the side of the ordinary boss, with a hole at right angles to the
hole on which the looper oscillates, and through this projection we propose to 'drill
a hole to receive a wire looper, by this means we are enabled to renew the looper
hook without a complete new lever and also adjust the looper more accurately than
has been done hitherto.
We also propose to dispense with the ordinary mechanism and presser foot used
for clearing away the fringe from the looper, and substitute a stud fixed on the
bottom part of the ordinary presser foot used for pressing on the fabric as it is
being sewn, on this stud we propose to fix an adjustable boss with a spring foot
attached, for pressing on the yarn or fringe the same being acted upon by the
mechanism which works the presser foot for moving the fabric forward.

Improvements in and relating to Sewing Machines for Fringing the
Edges of Textile Fabrics.
We THOMAS BARKER, SAMUEL SNAPE and WILLIAM WILSON of Phetheun
Street Works Bolton in the County of Lancaster Machinists 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 relates to sewing machines for fringing the edges of textile
fabrics and in order to more fully describe same, reference is made to accompanying
drawings.
Fig. 1 is a side elevation of the new spring foot.
Fig. 2 is an end elevation of the new spring foot.
Fig. 3 is a plan view of looper complete.
Fig. 4 is a side elevation of looper complete.

page_text: a Fig. 1 and 2 is the bottom part of an ordinary presser bar d'is a stud screwed
or fixed in same for carrying block b, c is a spring foot secured to block b. As the
ordinary presser bar a presses downwards it carries along with it the spring foot c
which holds the fringe in position and as the ordinary presser bar moves to
feed the fabric forward it also carries along spring foot c which clears the
fringe away. This mode dispenses with the usual cams, presser foot and slide
hitherto used.
On Fig. 3 and 4 E is the slide for carrying the looper is one end of the looper
lever 1 is a split ear or boss with hole bored to receive fringer hook f2. g is a
connecting rod with an eye at one end to oscillate on stud fixed in E the other end
of connecting rod g is screwed and passes through filbon g 1 which is secured and
regulated by two lock nuts as shewn g 2 is a stud fixed in the ordinary lever g 3 for
the filbon 1 to oscillate upon.

By this combination we dispense with the usual loose bracket on slide E and we
regulate position on slide E by the two lock nuts but in some cases we put a plain
connecting rod without thread and fasten same with a set screw in filbon g 1 or
filbon g 1 can be tapped and connecting rod g screwed to screw in filbon g 1. The
split ear or boss fl formed on lever is bored out to receive an adjustable
fringer hook f2. This fringer hook may be formed with a thread on to screw in
boss 1 or with a plain hole and two lock nuts as shewn on connecting rod 9 or it
may be formed with a plain hole or tapped hole and secured in various ways as
described for connecting rod 9.
This enables us to dispense with the ordinary forged looper and use an
adjustable and interchangable one thus securing a much easier and more effective
adjustment than has been possible hitherto.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same has to be performed, we declare that what
we claim is
1. A spring foot attached to the ordinary presser foot substantially as described
and illustrated.
2. An adjustable connecting rod substantially as described and illustrated.
3. An adjustable and interchangable fringer hook, substantially as described and
illustrated.
