PROVISIONAL SPECIFICATION.
An Improved Binding Attachment for Sewing Machines.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by George Wissler, of Cincinnati, Ohio, U.S.A.
Inventor,) to be as follows:-
This invention relates to an improved binding attachment for the purpose of
delivering binding in the proper shape and position, ready to be sewed onto the
material to which it is to be attached.
The attachment is adapted to be secured to the table adjacent to the needle by
means of a thumb screw in the usual manner. The delivery opening of the
attachment is formed by the smaller end of a funnel-shaped piece of metal which
is open at its side. and has its open edges turned inwardly. In combination with
this piece of metal is a U-shaped guide piece supported within the main body by
the inturned edges of the latter in such manner as to have its round portion con-
centric with the round part of the said main body, and its free sides parallel with
the flat sides of the former, said free sides reaching into the space between the
main body and its inturned edges.
Dated this 21st day of December 1800.

COMPLETE SPECIFICATION.
An Improved Binding Attachment for Sewing Machines.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by George Wissler, of Cincinnati, Ohio, U.S.A.
Inventor,) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
My invention relates to an attachment for sewing-machines whereby they are
put in condition to do some special work in addition to the ordinary sewing.
The special object of the attachment under consideration is to sew on binding
cut out of cloth, cotton goods, and other similar fabrics. Binding of this character
not having a selvage-edge, like a so-called "ribbon-binding" (which has one,) must
have its edges turned in in order to prevent them fraying out. Such cut fabric-
binding is in many cases cheaper than ribbon-binding, and it is also preferable in
cases where it is desirable to have the binding of the exact shade and colour of the
balance of the material, and in which case the former is simply cut off in strips
from the same material.
The specific construction of this attachment is fully explained in the following
description and illustrated in the accompanying drawings, in which-
Fig. 1 is a perspective view showing the attachment in position and also adjacent
parts of the sewing-machine.
Fig. 2 is an end view of the attachment showing its smaller end, the one which
is turned toward the needle.
Fig. 3 shows the larger end of the attachment, the one remote from the needle.
Fig. 4 is a section of the attachment taken on a line 4 4 of Fig. 2 and looking
to the left from this line.
Fig. 5 is a central horizontal view of the attachment.

Fig. 6 is a vertical section, of the attachment taken on the line 4 4 of Fig. 2
and looking to the right from the said section-line. This latter view also shows
the presser-foot in its relative position.
Fig. 7 is a rear view of the presser-foot.
Figs. 2 to 7 are enlarged.
9 is the bed-plate of a suitable sewing-machine.
10 is the slide; 11 the face-plate; 12, the presser-bar; 13, the presser-foot;
14, the needle-bar; and 15 the needle.
16 is the attachment having a slotted lateral extension 17, whereby it is held in
. position by means of a set-screw 18.
19 is the main body of the attachment consisting of a funnel-shaped piece of
sheet-metal having its side cut open, and its cut edges 20 bent at a point indicated
by 21 and turned in along a straight line passing through this point. These
turned in portions of the main body are not of uniform width, as is most plainly
shown in Fig. 5.
22 is another piece of metal bent semi-circularly, its inner opening a little wider
that its outer one, and its edges 23 reaching into the space between the main
body 19 and its inturned edges 20, to the extreme innermost termination of
which edges piece 22 is connected preferably by soldering, and thus held in
. position.
24 is a guide-bar by which the binding is forced to assume the proper shape and
position within the attachment while being fed into it. The width of the binding
cannot be more than the length of the space between this guide-bar and the main
body of the attachment, but it may be a little smaller.
The binding is preferably cut somewhat pointed in order to facilitate at the
beginning its introduction into the attachment. (See Fig. 1.) Guide-bar 24
keeps the binding close against the inside of the body 19, which, by its cou-
vergency gradually turns its edges over and toward each other as the binding
approaches the narrower exit end. This places the binding in its proper position
around the edge of the material which is to be around its edges, not being turned
in yet. Having, therefore, a binding cut in strips from larger pieces and having
no selvage edge it becomes necessary to turn its cut edges in and sew them on
in this position in order to prevent their fraying out. This binding is so cut
that its width is in excess of the length of the discharge-mouth of the attach-
ment measured from one point 21 around to the other one. As a consequence,
the edges of the binding, after having passed edges 23 of piece 22 and reached
point 21 inside of the attachment, will be compelled to follow its inturned
edges 20, and passing around edges 23, are finally forced into the space between
the infolded edges of the attachment and the corners 23 of the piece 22.
In this shape the binding is now doubled and sewed on, the needle 15 passing
through the same in a position as shown in Fig. 2, fully catching and securing
its inturned edges. The thus doubled edges of the binding as the latter passes
from the attachment are held up and kept constantly in proper position by the
inner edges 23 which prevent the binding from receding or otherwise passing out
from the path of the needle.
It is necessary to have the attachment not too close to the needle for the reason
that the upper half of the delivery-opening holds the upper half of the binding
somewhat up,
and thus prevents the sewing-machine from drawing the strip tight.
If, however, placed somewhat away from the needle the paid-out binding has
become sufficiently slack so as not to interfere with the tension devices of the
machine.
To equalize the pressure of the presser-foot on all parts of the material as it
passes through the machine, part of its under side or face has been cut away to
provide sufficient room for the increased thickness caused by the upwise-doubled
material of the binding. (See Figs. 6 and 7.)
The peculiar construction of this attachment makes it possible to use profitably
binding of the nature described, inasmuch as it can be sewed on quickly and with

page_text: one stitching, whereas now the sewing on of such binding is such a tedious and
laborious operation that it cannot be used with advantage. I am aware that
there are binding attachments performing the same function, but they differ greatly
in their specific construction, and in many cases are very complicated.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A binding-attachment for the purpose of delivering binding in the proper
shape and position ready to be sewed onto the material to which it is to be attached,
its delivering opening being formed by the smaller end of a funnel-shaped piece
of metal which is open on its side, and has its open edges turned inwardly in
combination with a U-shaped guide-piece supported within the main body by the
inturned edges of the latter, in such a manner as to have its round portion con-
centric with the round part of the said main body, and its free sides parallel with
the flat sides of the former, said free sides reaching into the space between the
main body and its inturned edges, substantially as shown and described.
2. An attachment for turning in the edges of binding, consisting of the com-
bination of a funnel-shaped piece of metal open on its side, and having its open
edges turned in as shown, an internal guide-piece supported by the said inturned
edges at and within the delivery end, and being substantially parallel and con-
centric with the main body, and a guide-bar secured within the latter, and at
the receiving end of the attachment being also concentric with it, and used for
the purpose of supporting the infeeding binding in proper shape, all as fully shown
and described.
