PROVISIONAL SPECIFICATION.
An Improved Binder for Sewing Machines.
We WILLIAM HENRY FORD BREWERTON and HARRY CHARLES KEMP, both of the
City and County of Bristol, Stay Cutters, do hereby declare the nature of our said
invention to be as follows:-
The object of our invention is to manufacture an improved form and construction
of "binder" for binding all kinds of materials by means of sewing machines.
Our invention consists of a small plate, provided with means for readily attaching
the same to the cloth plate of the sewing machine, (herein-after called the "binder-
plate") a number of vertical pins are fitted to the binder-plate, between which the
binding material is threaded in a zig zag fashion to impart tension thereto.
The binder plate is also fitted with a wire guide, bent to a suitable shape, so as to
lead the binding material to the guide, which consists of a plate attached to the edge
of the binder-plate, having a sharp bend formed therein or thereto, and a wire above
to keep the material in position.
This guide is so formed as to impart to either edge of the material an outward
tendency, and then, by a sharp turn, at a right angle, on leaving the guide, the folded
edge is brought inward, in which form it passos under the foot of the machine. .
Our invention possesses the following advantages
The guide being open, there is less liklihood of the work being caught in passing
through it. It creases the binding material as well as folds it.

COMPLETE SPECIFICATION.
An Improved Binder for Sewing Machines.
We WILLIAM HENRY FORD BREWERTON and HARRY CHARLES KEMP both of the
City of Bristol, Stay Makers 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 :-
This Invention relates to an improved binder attachment for sewing machines and
in order that this specification may be well understood there is hereunto annexed a
sheet of drawings similar letters of which refer to like parts.
The object of our invention is to manufacture an improved form and construction
of binder attachment or device for folding, creasing, and putting on an edging or
binding to various materials by means of sewing machines.
Our invention consists of a small plate provided with means for readily attaching
the same to the cloth plate of the sewing machine (hereinafter called the binder-plate).
A number of upright pins are fitted to the binder-plate between which the binding
material is threaded or interlaced in a zig-zag manner to impart tension thereto.
The binder-plate is also fitted with a wire guide bent to shape so as to lead the
binding material, with a preliminary determination to a fold to the guide proper
which consists of a plate attached at right angles to the edge of the binder-plate and
having a sharp bend formed therein or thereto the bend standing out therefrom, and
a wire pressing piece is arranged above the said bend to keep or hold the binding
material in position in passing forward on the guide.
The said guide is so formed as to impart to either edge of the material an outward
tendency and then by a sharp turn, at a right angle, on leaving the guide, the
folded edge is brought inward, in which form it passes under the presser foot of
the sewing machine.

page_text: Our invention is characterised by the following particular advantages, nizt.-
The guide being open, there is less liklihood of the work being caught in passing
through it.
It creases the binding material as well as folds it..
In the drawings, Fig. 1, is a top view of the binder; Fig 2, is a front view of
Fig. 1, and Fig. 3, is a back view of Fig. 1. a are the vertical pins carried on the
plate A, between which pins a, is threaded or interlaced, the binding material, the
tension to which may be increased or reduced by interlacing with a greater or
lesser number of the pins a.
A corner edge of the plate A', is turned up for the purpose of laying outward
and directing the lower edge of the binding material in smoothly. passing to and
through the binder. The material is then brought against the wire guide b, which is
so shaped with a half bend as to lead the binding material into a partial crease.
The material is then conducted against the side of a plate B, which is connected
vertically to the edge of the plate A. and has a sharp bend formed therein, or connected
therewith as shown at c. A wire guard d, is fixed above this bent portion c, to keep
the material in position against the shaped side of the plate B. The plate A, is
further formed with, or has connected thereto a small blade-like, or otherwise suitably
formed plate D, extending underneath the shaped part e, of the plate B, which acts
as a tucker to the edge of the material, keeping it in position underneath the
shaped part c In passing over the latter the edges are turned outward. The material
is then brought at a sharp right angle, as indicated by the dotted line a¹, and leaves
the guide with its edges turned inwards and is thus prepared for passing to and through
the attaching machine.
The dotted line a, a, of Fig. 1, indicates the course of the binding material to and
through the binder and to the presser foot of the sewing machine.
The last of the upright bars a, is filed across diagonally at a', Fig. 3, to increase
the frictional tension on the passing material and to give it a tendency or lead down-
wards towards the turned piece A. E, is the slotted hole for the holding screw for
attachment to the cloth plate of the machine.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed we claim
First. An open guide attachable to a sewing machine by which the danger of the
binding material catching in passing through a guide of ordinary tubular form is
minimised constructed and operating as and for the purposes herein described and
shown by the drawings.
Second. The means for and the method by which the binding material of various
consistency, either with or without selvage, is creased as well as folded in its passage
through the guide having the parts A', b, B c, d substantially as and for the purposes
herein described and as shewn by the drawings.
Third. The general construction arrangement and combination of parts constituting
our improvements in binders for sewing machines as and for the purpose herein set
forth.
