FAN ATTACHMENT FOR SEWING-MACHINES.SpeoMcation of
Application filed April 1,'To all whom it may. concern
Be it known that I, JOHN D. WARmmi , a
citizen of the United States, residing .at
Deweyville, in the county of Newton and
5 State of Texas, have invented certain new
and useful Improvements in Fan Attach-
ments for Sewing-Machines, of which the
following is a specification, reference being
had to the accompanying. drawings.'
10 This invention relates to new and useful
improvements in fan attachments for sew-.
ing machines, the main object of the inven-
tion being the provision of a fan which is.
adapted to be removably applied to the fly
15 wheel of a sewing machine, in order to gen-
erate an air draft during the operation of
the machine.
Another object of the invention resides in
the provision of a fan attachment of the
20 above character which will possess advan-
tages in points of efficiency and durability,
is inexpensive to manufacture and, at the
same time, is simple in construction and op-
eration.
25 With the above and other objects in view,
the invention consists in the novel features
of construction, combination and arrange-
ment of parts as will be hereinafter referred
to and more particularly pointed out in the
3o specification and claims.
In the accompanying drawing forming a
part of this specification, Figure 1 is a front
elevation of a fan attachment constructed in
accordance with my invention; and Fig. 2
35 is a transverse sectional view taken on the
line 2-2, Fig. 1.
Referring more particularly to the draw-
ing, 1 indicates the fly wheel of a sewing
machine, upon which my improved fan is
40 adapted to be 'mounted. The fan attach-
ment includes a circular split band 2 which
is substantially arcuate in cross section, so
as to conform to the curvature of the pe-
riphery of the fly wheel 1. The annular side
45 edges of the band 2 are bent upon them-
selves to form channels 3, in which the bind-
ing rings 4 are mounted. It will be noted
that the band 2 contains sufficient resili-
ency so that when the same is arranged
50 upon the periphery of the wheel 1, it will
be readily retained against outward move-
ment until pressure is applied thereto and
the retaining wires or rings 4 will securely1,114,076.

hold' the band against lateral movement.
Formed'integral with the band 1 and pro-. 55
jecting from the outer side thereof, are,-the
spaced ears 5, to which are secured the fan
blades 6, said blades being provided with a
reduced portion 7 adapted to be arranged
between the ears 5 and riveted or otherwise 60
secured thereto.
From the above it will be readily appar-
ent that. my improved fan attachment may
be quickly and readily applied to the fly
wheel of a sewing machine or removed 65
therefrom. It will also be apparent that
after the band is arraged in position upon
the fly wheel 1, the wire rings 4 will engage
upon opposite sides of the wheel and retain
the band against lateral movement, and it 70
will be apparent that the resiliency of the
band 2 will be sufficient to clamp the same
tightly upon the wheel, said band being
formed of galvanized iron or heavy tin. It
will also be apparent that the device may ,75
be applied to a sewing machine wheel,
whereby the air draft therefrom may be pro-
jected toward the operator or in the oppo-
site direction. It will also be apparent that
the device is extremely simple in construe- 80
tion and can be manufactured and placed
upon the market at a comparatively low
cost.
While 'I have shown and described the
preferred form of my invention, it will be 85
obvious that various changes in the details
of construction and in the proportions may
be resorted to for successfully carrying my
invention into practice, without sacrificing
any of the novel features or departing from 90
the scope of the appended claims.
Having thus described this invention,
what I claim is:-
1: A device of the class' described includ-
ing a split band substantially arcuate in 95
cross section, the annular edges of said band
being bent upon themselves to form bead-
ings, retaining rings arranged within said
readings, and a plurality of fan blades se-
cured to the outer faces of said band at one 100
side thereof.
2. A device of the class described includ-
ing a split band, substantially arcuate in
cross section and having its annular edges
bent upon themselves to form projections, 10
yieldable retaining rings arranged within
