PROVISIONAL SPECIFICATION.
Improved Folding Attachment for Sewing Machines.
1, PERCY RICHARD JULIUS WILLIS, of 55 Chancery Lane, in the County of
London, Engineer, do hereby declare the nature of this invention (a communication
to me from abroad by Mary Tobener, of Gold Hill, Nevada, U.S.A., Inventor,) to
be as follows:-
This invention relates to sewing machine attachments of that class known as
folders or seam finishers, and it has for its object to fold or finish a seam by
a simple construction and arrangement of parts which are readily attachable or
detachable to and from a sewing machine.
The attachment comprises an arm formed at one end with an apertured
enlargement to accommodate a thumb-screw for attaching the arm to the presser
bar of a sewing machine. The folding device is secured in any desired manner to
the other end of the arm, and consists of an approximately triangular shaped piece
of sheet metal folded into a conical sleeve. The edges of the metal are turned
inwards and soldered or otherwise secured together. These inturned edges form a
device for dividing and turning over the edges of the cloth passed through the
sleeve. A slot is made on the opposite side of the sleeve to that upon which the
edges are turned in to permit the passage therethrough of the cloth, which is fed
in from the larger end of the sleeve.
Dated this 31st day of December 1894.
1, PERCY RICHARD JULIUS WILLIS, of 55 Chancery Lane, in the County of
London, Engineer, do hereby declare the nature of this invention (a communi-
cation to me from abroad by Mary Tobener, of Gold Hill, Nevada, 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:-
This invention relates to sewing machine attachments of that class known as
folder or seam finishers, and has for its object to fold or finish a seam by a simple
construction and arrangement of parts which are readily attachable or detachable
to and from a sewing machine.
With this and other objects in view the invention consists of the construction and
arrangement of the several parts which will be more fully hereinafter described and
claimed.

operative position.

page_text: Fig. 6 is a side elevation of the device.
Similar numerals of reference are employed to indicate corresponding parts in
the several figures.
Referring to the drawings, the numeral 1 designates an arm, having a loop or
sleeve 2 at one end thereof, in which is fitted a removable fastening screw 3, having
a portion of its shank smouth and not threaded. This construction is for the
purpose of securing the attachment to a sewing machine but it is to be understood
that no stress is to be laid upon this arrangement, as any preferred means may be
employed for applying the attachment. The arm 1 is positioned in the proper
plane and at the proper angle to accomodate the attachment and operation of the
device, and at its free end is secured a conical shaped folding sleeve 4, with a slot 5
extending the full length of one side thereof. Within the said conical sleeve is a
divider 6, formed by inturning the edges of the said sleeve on the side opposite that
to which the slot is formed, and the said divider stands away from the side of the
sleeve in which the said slot is located. The divider extends through the larger
end of the sleeve, and throughout its length it partakes of the same degree of width
proportionately to the increase of the width of the said sleeve from its smaller
toward its larger end. The end of the divider which projects through the sleeve is
separated and the two parts are bent laterally in opposite directions at slight
oblique angles to provide folders or formers 7.
The fabric to be folded has the two edges thereof placed in the slot 5 and is
turned and fed to the needle and simultaneously connected to produce the form
shown in Fig. 5. It will be seen that this finishes a seam and makes a strong
connection without the use of binding. When the two pieces of fabric are inserted
in the slot, the edge of each is caused to assume a position on opposite sides of the
divider, and as they are drawn under, are turned inward or under, and in this
condition are ready to be scamed by the machine.
The attachment entire is simple and effective in its construction and operation,
is easily manufactured, and can be readily applied or detached. It is adapted to
be used in connection with any form or make of machine, and the essential feature
of the invention resides in the conical sleeve and the divider therein of the nature
set forth.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In a sewing machine attachment for the purpose set forth, a conical sleeve
suitably supported having a dividing partition secured to one of the inner sides of
the sleeve and extending toward the opposite inner side thereof, said divider
extending through and projecting outwardly from the larger end of said sleeve, and
tapering proportionately to the taper of the sleeve, with the parts of said free
projecting end extended laterally in opposite directions, said sleeve directly opposite
the dividing partition having a slot extending throughout the length thereof,
substantially as described.
