SPECIFICATION,
I JOHN CLAYTON MEWBURN of 169 Fleet Street in the City of London Fellow of
the Institute of Patent Agents communicated to him from abroad by Charles
Francis Norton Sewing Machine Maker and Henry Charles Mervin Engineer both
of Melbourne Victoria do hereby declare the nature of my invention for AN
IMPROVED HEMMING AND FELLING CONTRIVANCE FOR ATTACHMENT TO BEWING
MACHINES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention consists of a contrivance for attachment to sewing machines and
is for the purpose of supplying the fabric to the presser foot so folded as to form a
hem or a single or double fell as the operator may determine. This contrivance
consists simply of a piece of plate metal bent into certain convolute curves and
slightly tapering from its feed end to its discharge end, and also flattened towards
said discharge end. At the discharge end where these curves are flattened down a
slot is made so as to allow the folds of the fabric to come close together before they
are discharged. The discharge from this contrivance is the feed to the ordinary
presser foot.
Referring to the annexed drawings Figure 1 shews perspective of the improved
contrivance with a connected plate for fastening it into position on the sewing
machine. Figure 2 is a top view, Figure 3 side view, Figure 4 feed end view and
Figure 5 discharge end view. Figure 6 is another perspective view with the fold
of the contrivance bent back in order to shew the slot a at the flattened and
discharge end of same, a similar slot 6 being made in the opposite fold indicated
only in Figure 5. Figures 7 to 10 each shew the same view of the feed end of the
contrivance, the dotted lines in each case representing the fabric. In Figure 7 it
will be seen that there are two pieces of fabric 1 and 2 to be sewn together by
what I call a double fell, one piece is fed through the top opening A, and the other
through the lower opening B until they assume the position shewn, they are then
both guided towards the tapering and flattened end of the contrivance from
whence they issue to and are seized by the presser foot and the ordinary sewing
machine feed and conducted under the needle. In Figure 8 the only difference is
that the lower fabric is not fed so far through the curves and so what I call a
single fell is produced. In Figures 9 and 10 the contrivance is simply a hemmer,

through the bottom opening B. The slots a and b in Figures and 6 and the
flattening of the discharge end of the contrivance are for the purpose of pressing
the several folds of the fabric closely together before being presented to the
presser foot.
The contrivance is made of any kind of sheet metal that is sufficiently pliable
for the purpose and I have shown it with a slotted connection C so as to allow of
its adjustment to machines of various makes but this part C is no part of the
invention. I have shewn the invention full working size, but of course it may be
made larger or smaller if so preferred.
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.:-
The improved hemming and felling contrivance for attachment to sewing
machines substantially as herein described and explained and as illustrated in the
drawings.
