An Improvement in or applicable to Sewing Machines.
I, WILLIAM OWEN, of 48, Moorland Road, Burslem, Staffordshire, Potters'
Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improvement in or applicable to sewing machines,
the object of the invention being to apply to such machines means of readily
re-pointing needles which have become blunted by use in such machines,
such means being also available for use in sharpening the blades of pen-knives,
scizzors and for like uses.
To this end, the invention consists in the application to any convenient rota-
table axis or part of the sewing machine of a grinding wheel so located as to
permit of the needle or other article to be re-pointed or sharpened, being, con-
veniently held in the desired relation to the wheel, which is rotated by the
rotation of the part of the sewing machine to which it is applied.
The wheel may be made of a cylindrical form or of a tapering form, and may
be flat, convex, concave, plain or grooved on its peripheral face and may have
flat, parallel or convexed ends, so that both its peripheral and end surfaces may
be used and applied to the stated purpose of utility.
.
The wheel may be applied to the sewing machine in various ways, among
which, may be mentioned that, it may be mounted upon an ordinary sewing
machine bobbin, which, with the wheel so mounted, may be placed in position
for rotation in the bobbin refilling attachment in same manner and by same
means as when the bobbin is required to be refilled with cotton, so that, upon
such means being revolved, the abrasive wheel will be rotated therewith and may
be used for the purpose of the invention by applying the blunted point of the
needle or of the article to be re-pointed or re-sharpened to the periphery or side
edge thereof, as may be best suitable to the desired sharpening effect."
The wheel may also be applied to the machine by making it as part of the
small frictional wheel which, by contact with the fly wheel, rotates the bobbin
carrier and bobbin, or it can be removably or permanently secured to the spindle
of the bobbin carrier, either at the driven end of the latter, or at the other end
thereof, and, when removably applied thereto, it may be screwed on and off, or
its centre may be cored of a slightly tapering formation so as to facilitate its
placement on and removal from the correspondingly shaped spindle end of the
said carrier. Or, the grinding wheel may be attached to the sewing machine
fly-wheel axis, or, as aforesaid, to any other convenient rotatable part of the
sewing machine.
The special advantage of the attachment is that, in lieu of the blunted needles
being thrown aside when unfit for further use, for the want of a convenient
means of re-pointing them and rendering them fit for use, (hones and other
sharpening appliances seldom being handy,) a means is provided, forming, if
desired. a permanent attachment to the sewing machine, which, while not
interfering with the utility of the same for its intended uses, will serve the

fit for further use the part of the sewing machine upon which its utility is
principally dependent.

An Improvement in or applicable to Sewing Machines.
I, WILLIAM OWEN, of 48, Moorland Road, Burslem, Staffordshire, Potters'
Agent, 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 improvement in or applicable to sewing machines,
the object of the invention being to apply to such machines means of readily
re-pointing needles which have been become blunted by use in such machines,
such means being also available for use in sharpening the blades of pen-knives,
scizzors and for like uses.
To this end, the invention consists in the application to any convenient rota-
table axis or part of the sewing machine of a grinding wheel so located as to
permit of the needle or other article to be re-pointed or sharpened, being con-
veniently held in the desired relation to the wheel, which is rotated by the
rotation of the part of the sewing machine to which it is applied.
The wheel may be made of cylindrical form or of a tapering form, and may
be flat, convex, concave, plain or grooved on its peripheral face and may have
flat, parallel or convexed ends, so that both its peripheral and end surfaces may
be used and applied to the stated purpose of utility.
The wheel may be applied to the sewing machine in various ways, among
which, may be mentioned that, it may be mounted upon an ordinary sewing
machine bobbin, which with the wheel so mounted may be placed in position
for rotation in the bobbin refilling attachment in same manner and by same
means as when the bobbin is required to be refilled with cotton, so that, upon
such means being revolved, the abrasive wheel will be rotated therewith and may
be used for the purpose of the invention by applying the blunted point of the
needle or of the article to be re-pointed or re-sharpened to the periphery or side
edge thereof, as may be best suitable to the desired sharpening effect."
The wheel may also be applied to the machine by making it as part of the
small frictional wheel which, by contact with the fly wheel, rotates the bobbin
carrier and bobbin, or it can be removably or permanently secured to the spindle
of the bobbin carrier, either at the driven end of the latter, or at the other end
thereof, and, when removably applied thereto, it may be screwed on and off, or
its centre may be cored of a slightly tapering formation so as to facilitate its
placement on and removal from the correspondingly shaped spindle end of the
said carrier. Or, the grinding wheel may be attached to the sewing machine
fly-wheel axis, or, as aforesaid, to any other convenient rotatable part of the
sewing machine.
The accompanying drawing represents, by way of example, one of the ways
herein before referred to of removably applying the abrasive wheel which is
indicated by the reference letter a, showing it as applied to the driven end b,

page_text: of the bobbin carrier of an ordinary bobbin refilling attachment, the spindle c,
of which is prolonged beyond the small frictional wheel, d, (hereinbefore referred
to and which is driven by contact with the fly-wheel, e, and rotates the bobbin
carrier and bobbin,) and is tapered to carry the wheel, a, the hub of which may
be rubber lined at a¹, to facilitate its placement and removal on the spindle
and to ensure its frictional hold without liability of its splitting.
The special advantage of the invention is, that, in lieu of the blunted needles
being thrown aside when unfit for further use for the want of a convenient
means of re-pointing them and rendering them fit for use, (hones and other
sharpening appliances seldom being handy,) a means is provided forming, if
desired, a permanent attachment to the sewing machine, and which, while not
interfering with the utility of the same for its intended uses, will serve the
further purpose of being handy for immediately re-sharpening and rendering
fit for further use the part of the sewing machine upon which its utility is.
principally dependent.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
The application to any convenient rotatable axis or part of a sewing machine
of an abrasive or grinding wheel so located as to permit of the needle or other
article to be sharpened being conveniently held in the desired relation to the
wheel which is rotated by the rotation of the part of the sewing machine to which
it is applied, substantially as hereinbefore described.
