Improvements in Apparatus for Displaying Signs or Advertisements.
I DAVID LOUIS MACDONALD, of Fairview, in the County of Bergen, State of
New Jersey, United States of America, Clerk, 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 consists in securing disks or plates upon which signs or advertise-
ments are to be printed or painted to the ends of axle-trees of vehicles in a fixed
or stationary position, so that the inscription thereon may be easily read while the
vehicle is in motion.
Figure 1 represents a side elevation of a wagon, to the ends of the axletrees of
which are secured disks or plates, upon which signs or advertisements are to be
printed or painted.
Fig. 2 represents an edge view of a wheel and fragment of an axletree with the
advertising disk in section, to show one practical method of securing the disks or
plates to the ends of axletrees without interfering with the wheels thereon.
Fig. 3 represents a side elevation or face view of one of the advertising disks
detached from the axletree.
Fig. 4 is a sectional view of a paper disk provided with a metal rim for the
purpose
of stiffening and maintaining the disk in shape.
Fig. 5 represents a central sectional view of a disk of fibrous material or metal,
as preferred, punched into the required form, to be placed over the hub of a wheel
and secured to the end of the axletree and provided with a stiffening rib of corre-
sponding contour, as will be described. .
Similar letters of reference indicate corresponding parts throughout the several
views.
In the accompanying drawings, A represents disks or plates mounted upon and
secured to the ends of the axletrees B of a vehicle and firmly secured thereto in a
fixed position, so that the inscription thereon may be maintained in an upright
position to be read, or a painting properly displayed while the vehicle is in motion.
As a convenient means of securing these disks or plates to axletrees in common use,
braces or supports C are provided which receive and extend from the ends of the
axletrees in opposite directions over the hubs and behind the disks A, and to which
supports or braces C the plates or disks are secured by being riveted thereto, as
shown in Fig. 2, or in any other convenient manner. The central part of these
supports C are perforated to receive the ends of the axletrees and are retained in
position thereon by means of the nuts E, which retain the wheels upon the axle-
trees. By this means of securing advertising disks or plates upon the ends of
axletrees said disks become detachable without disturbing the wheels thereon and
may be quickly replaced by new ones, or the inscription thereon changed, as the
case may be, without injury to or disfiguring the wheels or axletrees, and while the
vehicle is in motion the inscription thereon easily read. In order to render these
disks as light as possible and to materially cheapen the cost of manufacture, they

page_text: may be made of paper board and stiffened so as to retain their shape and remain
flat by means of metal rims F, which rims, for convenience of construction and to
exclude the moisture-from-entering-the-edge of the board, are folded over and
around the edges of the disks, as represented in Fig. 4.
In Fig. 5 the disk A is punched or formed so as to receive and be secured to the
end of an axletree and extends forward over the hub sufficient to permit the disk A
to approach, but not to interfere with, the spokes of the wheel, the support C
conforming to the contour of the disk, as shown. It is not material that these
disks A be secured to the ends of the axletrees, so as to maintain them in a fixed
position thereon by means of the nuts E, as shown. Any other method of attaching
them may be substituted, if preferred; but utilizing the nuts with which the great
majority of vehicles are provided is believed to be preferable, because no new
device or attachment is required, no extra expense added, and may be readily fitted
to almost any vehicle in present use.
Having now particularly described and. ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. In combination with an axletree and wheel of a vehicle, a detachable plate
or disk adapted to be secured to the end of said axletree in a fixed position and
upon which plate or disk sigus or advertisements are to be displayed, substantially
as herein set forth and shown.
2. In combination with an axletree and wheel of a vehicle, a detachable plate or
disk of fibrous material adapted to be secured to the end of said axletree in a fixed
position, and upon which plate or disk signs or advertisements are to be displayed,
said plate or disk being provided with a metal rim, substantially as and for the
purpose set forth.
3. In combination with an axletree and wheel of a vehicle, a detachable plate or
disk adapted to be secured to the end of said axletree in a fixed position and
upon which plate or disk signs or advertisements are to be displayed, said plate or
disk being punched or formed so as to extend over the hub of a wheel, substantially
as and for the purpose herein set forth.
Dated this 22nd day of February 1893.
