ANTHONY B. McDOWELL, OF EDNA, TEXAS.
SEWING-MACHINE ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 465,722, dated December 22, 1891.
Application filed June 11, 1891. Serial No. 395,966. (No model.)To all wlhom it 7ncay concern:
Be it known that I, ANTHONY B. McDow-
ELL, residing at Edna, in the county of Jack-
son and State of Texas, have invented certain
5 new and useful Improvements in Sewing-Ma-
chine Attachments, of which the following is
a specification.
My invention relates to an attachment for
sewing- machines which can be quickly at-
o tached to the fly or hand wheel of the ma-
chine and which can be used for the purpose
of sharpening any instrument of small size-
such as needles, scissors, knives, &c.; and it
has for its object to provide an attachment of
15 this character which will be simple and
cheap in construction, which can be quickly
applied, and which will be effective for its
desired purpose.
My invention consists in the peculiar com-
20 bination and novel arrangement of the sev-
eral parts, all of which will be hereinafter
fully described in the annexed specification,
and particularly pointed out in the claims,
reference being had to the accompanying
25 drawings, in which-
Figurel is a sideviewof aportion of a sew-
ing-machine with my attachment applied.
Fig. 2 is a longitudinal section of the attach-
ment, and Fig. 3 is a perspective view thereof.
30 In the accompanying drawings, Aindicates
the fly-wheel and B, the attachment secured
thereto, such attachment consisting of a bar-
rel portion b, formed at its inner end with an
annular flange b', to which are detachably se-
35 cured a series of clamp-arms b2, made ofspring-steel, which arms are made in such
lengths as will suit the fly or hand wheel of
any of the ordinary machines. By referring
to Fig. 1 of the drawings, it will be observed
that said arms are formed with inwardly- 40
curved ends b", which slip over the wheel A,
as shown.
The barrel b is formed with a socket B',
into which the hub of the wheel A fits, such
barrel being reduced, as at B2, to form a spin- 45
dle for a grinding-wheel C, of emery or other
material suitable for the purpose desired,
such wheel being held against a shoulder B3
and on the pintle by the nut B'.
The advantage of my improvement as a 50
household convenience is that it can be at-
tached to or removed from the machine at
pleasure and can be used for sharpening not
only very small implements but table-knives
and the like. 55
IIaving thus described my invention, what
I claim and desire to secure by Letters Pat-
ent, is-
The combination, with the fly-wheel A, of
the grinding attachment, consisting of the 6o
barrel portion b, having a central socket B', ra-
dial spring-arms b2, secured to the barrel and
adapted to clamp over the wheel A, and the
grinding-wheel C, carried by and revolved
with the said barrel portion b, substantially
as and for the purpose described.
