Improvements in Signs for Advertising Purposes.
I, CHARLES ALEXANDER JACKSON, residing in the Town of Geneva, in the County
of Walworth, and State of Wisconsin, United States of America, Manufacturer,
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 follow-
ing statement:-
My invention has for its object the construction of a revolvable sign, adapted
to be so placed that a plate or disk forming part thereof may catch the force of
the wind and be constantly whirled around thereby, thus continuously exposing
both sides of said plate or disk, and the advertisements displayed thereon, to the
attention of any one passing by, and to that end the said invention consists in
certain peculiarities of construction and combination of parts, as hereinafter more
particularly set forth and illustrated in the accompanying drawings.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a representation of one form of my device, in elevation, partially
broken away or in section, to better illustrate certain details of construction.
Figure 2 is a detail sectional view, showing another construction.
Referring by letter to the drawings, A represents an ordinary post, or other
suitable support, to which my device may be attached. B represents a cylindrical
tube, attached to the post or support by staples C D. E is a supporting rod,
movable within said cylindrical tube, the said rod, above the top of the tube B,
being bent at a right angle, forming a horizontal part e, and then again bent at a
right angle and extended upward, forming an upper vertical part f. To this
upper part of the rod E there is secured, in any suitable manner (as by rivets gg)
a plate or disk F, on both sides of which the advertisement is to be displayed.
In the form shown in Figure 1, the cylindrical tube B is open at both ends,
and the lower vertical part of the rod E extends entirely therethrough, and is
preferably upset at the bottom, as shown at b, while in the form shown in
Figure 2, the bottom of the said tube B may be closed (though this is immaterial)
and the lower part of the rod E, near its lower end, is provided with an annular
exterior groove c, and the cylindrical tube B is formed with transverse holes d d
therethrough, in line therewith, so that the prongs of the staple C will extend
through said holes and said groove, into the support A. Both or only one of the
staples CD may thus pass through holes in the tube B and corresponding groove
or grooves in the rod E as desired. In order to prevent rain, snow or dust from
entering the tube B, I preferably close the top of said tube with a tight-fitting
steel washer h which surrounds the rod E just beneath the beginning of the first
bend e, and rests on the said top of tube E, as shown.
My device is intended to be placed on posts or other supports in fields or pas-
tures, along roadways or beside railroad tracks, or if desired against barns and
other buildings and to be so placed that the large plate or disk F will catch the
force of the wind, and be continually whirled around thereby, thus constantly

thereon, to the attention of any one. passing by, thus forming a very novel and
effective advertising device.
The object of upsetting the lower end of the rod E or grooving the said rod for
engagement with the supporting staples, is to prevent the sign from being pulled
away from its supporting cylinder B by the force of the wind. The upper part f
of the rod E is preferably flattened on one side in order to fit more closely to the
disk or plate F, this part of the rod thus forming what is called a half-round.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim, is
1. An advertising device, comprising an angularly bent rod, having upper and
lower upright portions and an intermediate connecting portion, said lower portion
being adapted for revoluble connection to a suitable support, and a plate or disk
secured to the upper portion of said rod, substantially as set forth.
2. An advertising device, comprising a supporting cylindrical tube, a bent rod
having upper and lower vertical portions and an intermediate connecting portion,
said lower vertical portion being revolubly supported within said tube, a plate or
disk secured to the upper vertical portion of the rod, and fastening devices for
securing said tube to a suitable support, substantially as set forth.
3. An advertising device, comprising an angularly bent continuous rod, having
upper and lower upright portions and an intermediate connecting portion, said
lower portion being adapted for revoluble connection to a suitable support, and
a plate or disk secured to the upper portion of said rod, with the center of gravity
of said plate or disk always at one side of and some little distance from the pivotal
point of the said rod, substantially as set forth.
4. An advertising device comprising an angularly bent continuous rod having
upper and lower upright portions and an intermediate connecting portion, the
upper portion of said rod being flattened on one surface, and the lower portion
of said rod being cylindrical, a cylindrical" tube for receiving and supporting the
said lower portion of the rod, fastening devices for preventing the accidental with-
drawal of the lower portion of the rod from the said tube, and a plate or' disk
secured against the flattened surface of the upper portion of the said rod, sub-
stantially as set forth.
