COMPLETE SPECIFICATION.
An Improved Apparatus for Advertising.
I, PATRICK FRANCIS MCCARTHY of 263 Collins Street, Melbourne, in the
Colony of Victoria, Advertising 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 :-
The object of this invention is to provide an attractive means of displaying
advertisements and is designed for use on. railway stations and at other public
resorts. I employ a case the front of which is provided at parts with. advertise-
ment spaces, whilst the central portion is provided with a large mirror in which
are openings or transparent faces. At the back of these openings or faces.
pictures or photographs are exhibited, which are displaced at regular intervals,
and another picture comes into view. The interior of the case contains mechanism
to produce the necessary motion of parts. to display the different. cards or pictures.
at intervals.
In order to make my invention clear I will now refer to the accompanying.
drawings in which-
Figure. 1 is a front. elevation of the case whilst
Figure 2 is a section at the back of same.
Figure 3 is a sectional elevation of the apparatus with the clock mechanism
ommitted.
Figure 4 is a sectional elevation at back of casing shewing clock work for operating.
the moving pictures.
Figures 5 and 6 shew a detail to an enlarged scale.
"A" represents a case the face of which is provided with a number of
advertisement spaces "B, B" and a portion of which is preferably formed with
silvered glass "C" which forms a mirror, portions "D,D" being left unsilvered.
for the display of cards or pictures as hereinafter described.
&
The mechanism for displaying the cards or pictures consists of a number of arms
"E" (preferably four) which radiate from a central bush which is set upon a
shaft "F" baving bearings in framing "G." Near the end of each arm "E".
pair of pins "E, E¹" is, provided which project towards the face of the case.
These pins are arranged to support cards or pictures "H" and are designed so.
that the picture when being exhibited will always be in its true position. A
square or rectangular opening "H" (Fig. 2) is formed in the cards "H" and the
said card is hung upon the pins "E" The pins are provided with discs, one at
each side of a card (see Figs. 5 and 6) for holding the cards in position during the
rotation of the arms.
The arms "E" carry the cards or pictures to be displayed at the central
pening "D¹." I will now describe mechanism for displaying cards or pictures at
be corner openings "D."
"J" is a
pulley set upon the shaft "F" behind or in front of the arms "E"
s desired. This pulley. carries belt "J" which operates a small pulley "J" "set.
pon a shaft "Ja" having bearings in framing of the case. This shaft "JS"
arries a pulley "K." Au endless belt "L" is arranged over this pulley, the said.
elt passing over similar pulleys "K" which latter are set upon shafts having.
earings supported from the casing "A" at suitable positions. The endless
D

page_text: belt "L" is provided with a number of pins "M" (see Figs. 2, 5, and 6) which are
arranged in pairs and are secured in any suitable manner to the belt. These pins
project towards the face of the case and are provided with discs or other holding
appliances as in the case of the pins "H." These pins are secured to the belting
at regular intervals and are arranged with a different amount of projection so that
during the rotation of the pulleys and motion of the endless belt "L" the
cards "N" supported ou said pins will not come in contact with each other but
will be free to swing and to assume the correct position when opposite a transparent
face of the glass or opening in the face of the apparatus. The cards "N" have
openings "N" similar to the openings "H" in the cards "H."
I do not confine myself to any particular mechanism for producing the motion to
the belt "L" and arms "E" for displaying the pictures, but I find that the
mechanism well known and employed in striking clocks is suitable for this purpose.
I have roughly indicated this mechanism on Figure 4, but may employ any other
suitable form of clockwork for the purpose.
"P" is a barrel which is set upon a spindle with a key "P1" and around which
a cord is wound. This cord passes over pulleys "Q, Q" and is secured to a
weight "R." The barrel "P" gears with a pinion on the shaft of the wheel "S"
which is in communication with the lever escapement mechanism. The clock
mechanism is wound at "T" and has spring movement and actuates the
striker "V."
The gong "W" is arranged to strike at preferably fifteen minutes intervals and
at the same time release mechanism and allow the weight "R" to act to unwind
the drum and cause a rotation of the spindle "F" so as to actuate the pulley "L"
and arms "E." The arms will be caused to rotate a quarter of a revolution so as
to move the picture being exhibited at the central opening "D" away from same
and stop when the next arm has brought its picture into position at the back of
such opening. At the same time the pictures being exhibited at the four corner
openings "D" will move with the belting "L" out of sight until the next pictures
on the belt have taken their places at the back of the said openings "D."
system of pulleys is geared with the central shaft so as to give a movement
sufficient to displace.one set of cards and bring another into position before an
open face of the mirror or opening in the front of the apparatus. This takes
place simultaneously with the sound of the gong and the movement of card at the
central aperture "D¹."
The
In some cases it may be found more convenient when constructing the apparatus
to place the endless belt carrying the pictures at back of the arms.
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 a casing as "A" upon which are advertisement spaces
as "B," open spaces as "D, D" at which pictures are displayed at intervals, and
mechanism for operating such pictures substantially as, and for the purposes set
forth.
2. In apparatus for advertising-
In combination a case as "A" having openings or faces as "D, D," a spindle
as "F" carrying arms as "E" to which pictures as "H" are hung substantially
as and for the purposes set forth.
3. In apparatus for advertising-
In combination a case as "A," pulleys "J, J2" connected by belt "J" and
arranged to operate an endless band as "L" on pulleys as "K" said band carrying
pictures as "N" substantially as and for the purposes set forth.
4. In apparatus for advertising-
The combination of cards as "N" having square or rectangular openings
as "N" with pins as "M" having discs as
"M1" as and for the purposes

page_text: 5. The combination and arrangement of the whole of the parts as herein
described and as illustrated on Figures 1, 2 and 3 of the accompanying
drawings.
