Improvements in Advertising Devices.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 an improvement in electrically operated advertising
devices, and consists in the novel features of construction and relative arrangement
of parts hereinafter fully described in the Specification, clearly illustrated in the
drawings.
Reference is to be had to the accompanying five sheets of drawings forming a
part of this application in which like characters are used to indicate like parts
wherever they occur.
Fig. 1 represents a front elevation of the invention shown as mounted in a
suitable casing.
Fig. 2 represents a rear elevation of the device, the casing being broken away
in order to show the construction of the several parts.
Fig. 3 represents a vertical section on the line 3-3 of Fig. 2 looking in the
direction of the arrow.
Fig. 4 represents a vertical section on the line 4-4 of Fig. 2 looking in the
direction of the arrow.
Fig. 5 represents a cross section on the line 5-5 of Fig. 3 looking in the
direction of the arrow.
Figs. 6 and 7 represent respectively front elevation and vertical sections of
the apparatus for making and breaking contact.
a represents a receptacle or casing suitably ornamented, and of any desired
configuration, provided with an aperture a' through which the advertisement
carried upon an endless belt b can be seen. This belt is preferably divided into a
series of spaces b', one for each particular individual advertisement. a 2 represents
adial provided with spaces or divisions a 3 in which may be arranged indexes of
the different classes of business advertised upon the belt b. This may be done by
printing the words, such as "Hardware," etc., or preferably, by placing in these
spaces the letters as shown. The letter "A," for instance, standing for any class
of advertisements beginning with this letter. In the center of said dial is arranged
an arm a 4 with a pointer a 5 arranged to register at any desired space a 3. In
order to maintain this pointer at any desired space it is provided on its under side
with a pin a 6 that engages in one of a series of depressions a 7 on the face of the
dial. The arm a 4 may be rigid, and this pin a 6 spring pressed or the pin may be
rigid with the arm, and the arm be made of spring metal. Preferably, however,
the pin is mounted in a depression, not shown, on the under side of the arm or
pointer, and pressed outwardly by a spring not shown. The dial and pointer, just
described, constitute an indicator. The arm a 4 is affixed to a short shaft a 8
extending through the front of the casing, and having upon its other end a bevelled

page_text: gear a 9 which meshes with a similar gear a 10 upon a shaft al (suitably
journalled upon a framework 40 that supports the several parts of the apparatus,
and is arranged within the casing a) having a gear a 12 upon its opposite end which
meshes with a gear a 13 upon one end of a downwardly extending shaft a 14 that
is suitably journalled upon said framework. The shaft a 14 has upon its lower end
a gear a 15 which meshes with a gear a 16 upon a horizontal shaft a 17 journalled
in suitable standards a 23 secured to the framework.
The helt b, or series of belts may be of cloth or any suitable material, and is
supported by rolls 62 journalled in suitable bearings secured to the upper and lower
part of the framework. Said rolls are arranged to be rotated by means of a
suitable motor 64 upon the shaft b5 on which there is an endless screw b6 which
meshes with a spur gear b7 rigid upon a shaft 68 upon which one of the rolls b2
is mounted. For the proper and accurate display of the advertisements, it is
necessary to cut off the power or break the circuit at the right number of
revolutions of the rolls, and also at the right point in said revolutions. This is
accomplished by connecting to the main source of power or the main circuit, an
auxiliary circuit both in circuit with the motor. The circuit breaking attachments
are arranged in the main circuit to break the main circuit at the right number of
revolutions of the rolls, and a circuit breaking attachment in the auxiliary circuit
arranged to break the auxiliary circuit and thus stop the machine at the right
point in the last of said revolutions. To this end it is necessary to have the
auxiliary circuit broken at each revolution, so that any desired number of
revolutions may be selected by means of the circuit breaking attachments in the
main circuit. After the main circuit is broken, the next breaking of the auxiliary
circuit serves to stop the machine, since it is only when both circuits are broken
that the current is shut off from the motor. The means for breaking the auxiliary
circuit comprises among other things, a disk 69, a lever 611 and brushes a 19.
A disk 9 is mounted upon the shaft b8, and is provided with a depression
arranged to be in the position shown in Fig. 4, while the advertisement appears in
front of the opening of the casing. 6" represents a lever pivoted at one end in
any suitable part of the framework 40 provided with a lug b 14 arranged to ride
upon the said disk and drop into said depression when an advertisement appears in
the space. The lever is pulled down by a spring a 18, when the lug 614 engages
the notch in the disk, and is arranged to be raised by the disk and its free end
brought into contact with the brushes a 19 connected to any suitable part of the
electrical circuit. The levers 6", disk 6 10 and brushes a constitute a make and
break device for the supplemental circuit, and act to break the supplemental circuit
at the right point of each or any revolution, another device hereinsfter described
serving to break the main circuit at the right number of revolutions. One of the
shafts a 20 on which one of the upper rolls is mounted, see Fig. 4, is arranged at
its ends in sliding blocks a 21. These blocks are mounted in suitable vertical
ways a 22 and are connected to screws a 24 mounted in lugs a 25 integral with the
framework. By means of these screws and the associated parts this shaft and
this rol! can be adjusted up and down in order to put any desired tension upon the
belt in order to prevent the latter from slipping. The belt will continue to
rotate as long as the current is connected to the motor, and during this time the
lug 614 on the lever 11 will ride on the disk, and the free end of said lever b 11
held in contact with the brushes a 19, except when the lug b 14 drops into the
depression 10 thus bringing the end of the lever away from, the brushes and
breaking the circuit. The lever 611 will, when the depression in the disk comes
opposite the lug 14, be pulled downward by the spring thus breaking the auxiliary
circuit. As the advertisements are spaced in accordance with the periphery of the
roll on the shalt that carries the disk, it follows that by breaking the main circuit
at the right number of revolutions of the roll that carries the disk, and afterwards
breaking the auxiliary circuit at the right point in the last of said revolutions by
means controlled by said roll itself any desired advertisement will be properly
placed before the opening. The means for breaking the main circuit are controlled

page_text: and arranged as follows; Upon the shaft 68 that carries the disk 69 and at the
opposite end thereof, is secured a pinion d that meshes with a spur gear d¹ fast
upon a shaft d2 suitably mounted in standards d 3 in the framework of the machine.
This shaft carries a pinion d 4 that meshes with a spur gear d5 loose upon the
shaft a 17. The gear 5, shaft a 17 and standards a 23 are made of conducting
material. A hollow pin d 6 of conducting material is secured in this gear and
projects toward the inside of the casing. Within the cavity d 7 of this pin there
is mounted a metal block d 8 pressed outwardly by a spring d 9 arranged between
the end of said block and the end of the cavity in the pin. This block is designed
to make contact with a disk d 10 rigidly mounted upon a hub d 11 made fast to the
shaft a 17 by a screw d 12 as shown. The disk d 10 is made of conducting material
and is provided with an aperture closed by a plug d 13 of non-conducting material.
This plug is arranged to be in the path of movement of the block d 8. The free
end of leaf-spring d 14 engages the disk d 10 near its periphery, the opposite end
of said spring being rigidly secured to an insulating block d 15 secured to the
framework adjacent to one of the standards a 23. f represents a suitable source
of electrical supply, as a battery, one wire f¹, of which connects with the switch f2,
the other wire f3 connects with the magnet f4 suitably mounted upon a standard f5
connected to the framework. Wire f3 leaving the magnet passes to the block d 15
and is secured to a binding screw f6 that passes through the spring d 14. By this
means the circuit is made from the battery to the disk d 10. The wire fafter
leaving the switch f2 is carried down to the bottom of the casing to a binding
block f7 having springs upon opposite sides thereof. This binding post is secured
to the base of standard 8 which is secured to the framework. In the top of this
standard f8 is journalled one end of the shaft b5 upon which the motor and
endless screw are mounted. The other end of said shaft being journalled in an
arm 24 secured to the framework of the machine. Near the standard f8 on this
shaft are mounted two disks f9 and f10. The disk f9 is fast upon the shaft and
the disk f10 movable. Wires f11 connect these disks and are provided midway
their ends with balls f12. As the shaft rotates these balls are thrown outward by
centrifugal force and tend to draw the disk f10 toward the disk f9 in proportion
to the speed of the shaft. Springs f13, 14 are secured at opposite sides of the
block 7 and are made of conducting material. The free end of the spring f14 is
arranged to be engaged by the disk f10 and to be forced into engagement with the
free end of the spring f13. The circuit from the battery by means of the wire f¹
is connected at one side to this block f7 and to the spring f13. From the
spring 14 the current is led by the wire to the motor, thence to the framework 40,
thence to the disk d 10, and thence to the binding post f6. The framework 40 is
made of conducting material, and a wire f50 connects a binding post f60 on the
framework 40 with the motor. A wire f30 is connected at one end to the spring d 14
by binding post f61 and its other end to the binding post f31 to which the
brushes a 19 are attached and serves to conduct the current to said brushes.
From the foregoing, it will be apparent that when the ends of the springs f13, 14
are in contact the circuit will be closed at this particular point, which, in the present
arrangement, will occur when the machine is at rest, and at all times except when
the speed is so high as to force the disk f10 toward the disk f9 and to permit the
end of the spring 14 to leave the end of the spring f 13, at which time the circuit.
will be broken and the motor stopped automatically. The wires f11 and their
attached balls and associated parts constitute a regulator or governor whereby the
current is automatically shut off in the event of an excess of speed. There are in
effect three switches or points where the main circuit may be closed or broken, to
wit 2, the springs f 13, 14 and the disk d 10, and block d 8, and the auxiliary
circuit is broken at the brushes a 19. f15 is a keeper or armature for the
magnet f4. This is pivoted at its lower end to a suitable bracket f17 secured to
the framework, and its free end is arranged to engage a lug f18 fast upon a
lever 19 pivoted between its ends to a standard f20 secured to the framewor

page_text: The free end of the armature 15 is kept in engagement with the lug 18 on the
lever 19 by means of a spring f21 mounted upon an adjusting screw f22 that
passes through the armature 15. This spring is arranged on its adjusting screw
between the armature and the standard f20 against which the free end of the screw
rests. This screw is a means for adjusting a path of movement of the armature and
also is a support for the spring. The lever 19 at one end is connected by a
spring 23 with the lower part of the framework. This end of the lever is
connected with a bell hammer f24 positioned to strike a bell f25 secured to the
framework whenever this end of the lever is depressed by the spring. A sliding
weight/26 mounted upon the arm of the lever 19 serves to adjust the movement
of said lever. A strap/27 is connected to the opposite end of the lever/19 from
that to which the bell hammer is secured and passed around a drum f28 upon the
shaft 65 and connected at its opposite end to a lug f47 upon the framework of the
motor. When the strap end of the lever 19 is raised the strap will be made to
hug the drum f28 and act as a brake to stop the motor. The strap is released from
the drum by a reverse movement of the lever. These operations are performed by
the movement of the spring f23 and the armature f15. When the circuit is closed
to start the motor, as hereinafter described, the magnet f4 is vitalized and attracts
its armature and forces its free end into engagement with the lug f18 on the
lever f 19 thereby raising the bell hammer end of said lever and lowering the strap
end, thus releasing the drum from the strap and the action of the brake. When,
however, the current is broken to stop the motor, the spring f23 will force the
bell hammer end of the lever/19 downward forcing the free end of the armature
toward the standard f20 and raising the brake end of the lever /19 and making
the strap engage the drum to act as a brake and stop the movement of the several
parts. It will be noticed that this strap acts in unison with the lug b 14 on the
lever 6 11 that engages the depression in the disk on the shaft 68. It will be
further observed that this brake device is automatically thrown out of
engagement when the circuit is closed and automatically thrown into engagement
when the circuit at the brushes a 19 is broken. The current of the main circuit
from the magnet f+ is conducted by the continuation of the wire 3, to binding
screw f6, spring d 14, disk d 10, block d 8, pin d 6, gear d 5, shaft a 17, standard a 23,
and thence by framework 40, wire f 50 to the motor. From the motor current is
led by wires f45 to the springs/14 and 13, thence by wire fi to battery. The
current for the auxiliary circuit is conducted from the post f61 by the wire f30 to
the brushes a 19, thence by the lever b11 to the framework 40, and thence to the
motor.
From the foregoing it will be seen that while the block d 8 and the disk d 10 are
in contact, supposing the switch f2 to be closed, the circuit will be closed and the
belts driven. When, however, the block d 8 engages the plug d 13 the circuit will
be broken at this point, but the machine will continue to run until the auxiliary
circuit is broken at the brushes a 19 whereby the current is cut off from the motor
entirely, and the mechanism stopped. The operation of the machine is as
follows:-
The switch 2 being closed, and it being desired to show at the opening the
advertisement relating say to "Laundry," the pointer arm is turned until the
register stops at the letter" L." This movement of the pointer arm is transmitted
by means of the shafts a 8, a 11, a 14, a 17, and their respective gears, and there
occurs a corresponding movement to the disk d 10 carrying the plug d 13 out of
engagement with the block d8 and closing the circuit thereby starting the motor.
The movement of the motor shaft is communicated to the shaft 8 by the screw
and thence to the belt, and at the same time by means of the gears d¹, d 5 to the
block d 8. This movement of the parts will continue until the plug d 13 engages
the block d 8 when the main circuit will be broken, as hereinbefore described, the
machine and motor continuing to be run by the current furnished through the
auxiliary circuit until said current is broken at the brushes a 19.

page_text: It is to be understood, of course, that the switch f2 is only an auxiliary
attachment for use when the machine is set aside for an indefinite length of time,
and to prevent accidental movements of the mechanism when the machine is being
exhibited or overhauled. This switch forms no part of the invention, since when
the circuit is closed, the switch is, or may be disregarded, the wire f¹ entering and
leaving the switch is one wire. When the disc d 10 is moved by means of the
pointer arm and the circuit closed, the armature f15 is operated to release the
motor shaft from the action of the band brake f27. The block d 8 in its rotation
re-engages plug d 13 thereby breaking the main circuit, and forcing the current
through the auxiliary circuit until the latter is broken by the lever b 11 dropping
away from the brushes a 19, whereupon the magnet f4 releases its hold upon its
armature permitting the band brake to be again put into operation. The framework
may be provided with suitable panels 41, and the opening may be protected by
glass 42 if desired. Preferably a ratchet is shown in dotted lines in Fig. 2 and
in edge view in Fig. 5 is mounted upon the shaft a 8. A spring-pressed pawl is
arranged to engage the teeth of this ratchet. By this construction a reverse
movement of the arm and of the disk d 10 is prevented it being necessary at all
times to move the arm in the direction of the arrows, Fig. 1.
We do not desire to be understood as limiting ourselves to the precise construction
and arrangement of the parts shown, as many modifications will suggest themselves
to those skilled in the art. The circuit breaking attachment mounted upon the
shaft a 17 can be variously modified without departing from the spirit and scope of
the invention, which includes two movable parts, one controlled by the indicator
and the other controlled by the belt mechanism.
The belt preferably passes over guide rolls 43 arranged near the top and bottom
of the opening a' in order to ensure the belt's position evenly before the opening.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
