Improvements in Advertising Apparatus.
I, THORVALD HANSEN, Mechanic, of 23, West First Street, Boston, Massa-
chusetts, United States of America, 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 relates to a display apparatus, and is hereinshown as embodied
in an apparatus especially applicable for advertising purposes.
In accordance with this invention, a series or plurality of frames are arranged
in sets which are bodily movable in opposite directions, and the said frames are
individually transferred from one set to another and when transferred are allowed
to rest for a suitable time to display the advertisement thereon, as will be described.
The frames referred to may and preferably will be made so as to receive cards
bearing the advertisement, which may be readily replaced when desired.
The apparatus is designed to contain a substantially large number of frames
in a substantially small space, as will be described.
These and other features of this invention will be pointed out in the claim at
the end of this specification.

Referring to the drawings, A represents an upper set or series of frames, and A¹
a lower set or series of like frames, which may be of metal or other material and
preferably open to receive cards bearing the advertisement, preferably on both
sides. The card-supporting frames of the sets A A' are movable in the present
instance in a cycle or endless path and are provided on their opposite sides with
suitable journals or projections a, (see Figs. 4 and 5) which enter into the end-
less path and are supported by the lower walls of the horizontal sections a¹ a² of
Din Q37

page_text: said path, which sections are connected, as shown, to vertical sections a³ at. The
endless paths, composed of the sections a¹ a² a³ at, may be made of channel-bars
and secured to the opposite sides as as of a supporting frame secured to the side
bars or rods a of a niain frame erected from a base a8.
The card-receiving frames are adapted to be transferred from one set, as A¹,
to the other, as A, and vice versa, by suitable carriers (shown as endless chains bb¹)
located at opposite sides of the apparatus and passed about sprocket-wheels 2,
mounted on shafts bb, supported at the top of the apparatus, and about sprocket-
wheels 667, mounted on shafts 68 69, supported at the lower part of the apparatus,
the shaft having a sprocket-wheel 6, connected by a sprocket-chain with a
sprocket-wheel 6, loose on a shaft but adapted to be rendered periodically
fast thereon, as will be described.
The endless carriers bb, as shown, are provided at suitable intervals with
supporting devices for the card-receiving frames, and the said devices are shown
as lugs or projecting bars 66. The lugs 16 act to support a frame of the lower
set while said frame is being carried or transferred to the upper set, and vice
versa, the said lugs projecting. beyond the inner wall of the vertical sections of
the raceway, (see Fig. 3) so as to carry the journals of the frames into the
horizontal sections a a² of said raceway.
The journals of the card-receiving frames when in horizontal sections of the
raceway are adapted to be moved therein, so as to move the frames bodily and
carry those received from one vertical section, as a³, to the other vertical
section a, and vice versu. The movement of the said frames in the lower
section a¹ may be effected by latches or hooked arms c, (see Fig. 4) one at each
side of the machine, which are pivoted to cranks c¹ fast on a shaft c, having a
crank joined by a link to one arm c (see Fig. 6) of an elbow lever c, having
its other arm provided with a stud or roller (see dotted lines Figs. 6 and 7)
which extends into a cam groove in the face or side of a gear 2 fast on the
shaft 6, the said gear having a hub c¹ fast to the said shaft and provided with a
peripheral came and worm gear c. The movement of the card-frames 'in the
upper horizontal section may be accomplished by similar latches or hooked arms d
pivoted to cranks d' on a shaft having a crank ³ joined by a link to a
crank on the shaft .
By reference to Fig. 2, it will be seen that the latches or hooked arms c, d
operate on the card-frames in opposite directions. The latches or arms c are pro-
vided with suitable pins which are adapted to ride upon inclined pieces or
cams attached to the sections at of the raceway, they being shown as part of
pieces d secured by screws 16 to the said sections. The cams d13 act to turn the
arms c on their pivots against the springs 7 and thereby lift the hooked end
above the level of the journals of the frames, and the forward movement of
said latches is sufficient to ensure their hooked ends being beyond the said
journals when the pins clear the cams and the arms drop down on the
said journals. The movement of the card-receiving frames bodily across the
apparatus is intermittent, and is effected as above described by the cam groove clu
acting on the stud or roller c. The movement of the card-receiving frames from
a lower to a higher set and vice versa is effected as above described by the endless
chains, which are intermittently moved, thereby allowing the card frames to be
stationary when opposite suitable openings in an enclosing case for the apparatus,
which case may be of wood or any suitable material and is not hereinshown.
The intermittent movement of the endless chains may be effected by mechanism
as will now be described.
Referring to Figs. 6 and 7, the shaft 4 has loose on it, a gear wheel 20 which
is driven by a gear loose on a stud or shaft and attached to a pinion or
gear which meshes with and is driven by the gear 2. The gear d20 has
projecting from one face a stud or pin which extends within the rim and
toward the web or plate of the sprocket wheel 613 and forms one member of a
clutch, the other member of which is a cross-bar 25 carried by the end of a lever

page_text: or arm pivoted to the inner face of the web or plate of the sprocket wheel,
the cross bar d extending through a slot 27 in the said web or plate to the
outer side thereof where it is adapted to co-operate with a crank or arm on a
rock-shaft d29, which has a second crank or arm 50 engaging the periphery of
the cam fast on the hub c. The sprocket wheel 3 is normally loose on the
shaft but is adapted to be rendered fast to the gear 2 by the engagement of
the pin or stud with the cross bar d, which is adapted to be lowered into
the path of movement of said stud or pin, when so permitted as will be described,
by a spring & acting on the arm or lever des (see dotted lines Fig. 6), the said
spring being attached at one end to the inner face of the web or plate of the
sprocket wheel.
The engagement of the stud or pin with the arm d is governed by the
peripheral cam c¹³, which at the proper time permits the crank du to move toward
the hub c and thereby rock the shaft so as to lower the end of the crank d
sufficiently to permit the cross bar to be moved by its spring d³ toward the
periphery of the sprocket wheel and into the path of movement of the stud d².
When the stud engages the cross bar d, the sprocket wheel is clutched to
the gear 20 and rotates therewith, thereby driving the shaft 69 and causing the
endless chains to travel so as to effect the transfer of a card-frame from one set
as A to the other set as A and vice versa.
The sprocket wheel is carried one revolution by the gear 20 and is then
stopped by the crank moving the cross bar toward the center of the wheel,
which movement of the crank is effected by the cam c, and during the next
revolution of the gear the sprocket wheel remains at rest, until the stud d² is
brought substantially into position to engage the cross bar, which is at such
time permitted by the crank to be moved by the spring ds into line with the
stud d
The horizontal sections a¹² of the endless path for the card-frames are provided
with springs which act as yielding abutments for the journals a, against which
said journals are held by the latched arms c, d, and which yield to permit the
journals on the endmost card-frame to be forced out of the horizontal section into
a vertical section, when a card frame is transferred from a vertical section into the
horizontal section at its opposite end. The vertical sections are provided with
springs, the upper ends of which extend into the horizontal sections a² and
are downwardly inclined (see Fig. 3) so as to assist the journals of the card-frames
into the horizontal sections a².
The shaft may be driven in any suitable manner and in the present instance
is shown as driven by an electric motor f having its armature shaft f³ provided
with a worm f6, which drives a worm gear fi on a shaft f having a worm f
which meshes with the worm gear.
The operation of the apparatus hereinshown may be briefly described as
follows; As shown in Fig. 2, the card-frames are at rest and the cards on the
endmost frames marked 2, 3, 4, 5 may be supposed to be opposite suitable open-
ings in the enclosing case not hereinshown. The shaft may be supposed to be
continuously in motion, and during each revolution, the can groove operates
on the lever and thereby causes the latches c, d to move forward but in opposite
directions to engage the journals of the card-frames 3, 5, and then to move back-
ward and carry with them the card-frames 3, 5, and at the same time move all
the card-frames in the horizontal sections a¹ a² of the raceway, a sufficient distance
to carry the said frames 2, 4, into the vertical sections 3 at of the raceway and
upon the lugs or projections 616 on the endless chains, which at this time is set in
motion in the direction indicated by arrow 20, thereby lifting the card-frame 2
from the lower set A¹ or from opposite the lower opening in the enclosing case.
up to the upper set A into line with the upper opening in said enclosing case,
and at the same time lowering the card-frame 4 from the upper set A to the lower
set A¹ and opposite an opening in that side of the enclosing case.
The card-frames exposed to view are allowed to remain opposite the openings

page_text: in the enclosing case, for a given length of time, which in the present instance
is while the gear 20 is making a revolution, and thereafter the said cards are
transferred as above described to display a new card.
It will be seen from an inspection of. Fig. 2, that the advertisement on one face
or side of the card-frame 2, is exposed to view in two positions, namely, while it is
the endmost card at the right of the sections a¹², and that the advertisement
on the other side of said frame is exposed to view while the card-frame is the
endmost one at the left of the said sections.
During the passage or movement of the card-frame from one end of the raceway
sections a¹ a to the other, the advertisement on the same is covered or removed
from view. In this manner, each card-frame may have attached to its opposite
sides two placards bearing two different advertisements or the same advertise-
ment, and in the former case, each advertisement is given two exposures during
the time the card-frame is traveling its complete cycle, and in the latter case the
advertisement is given four exposures, two on opposite sides of the apparatus. The
apparatus is capable of displaying a large number of different advertisements
and yet be of substantially small compass so as to take up substantially little
room..
The latches & are provided with pins d¹ which rest upon the sections a² and
these latches do not require the use of cams to elevate them, as the lugs 16 prac-
tically close the inlet end of the sections a² and form a solid abutment for the
journals a, when the latches d are moved forward to engage said journals. The
latches on their forward movement ride over the journals a and drop behind
the same.
The cams 13 are used on the lower sections a¹, as the inlet ends of
these sections are not closed by the lugs which are carried below the same, and
therefore the cams d are employed to prevent the latches c pushing the journals a
back into or toward the vertical sections, which would prevent engagement of
the latches c with said journals.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
