As illustrated in the drawings, the present 30
invention is embodied in a new and novel car
rying case for transporting a combined sound
reproducing and picture projecting apparatus
which may be quickly set up for operation in
a simple and convenient manner.
A feature of 35
the carrying case is that, when closed, it will
hold the several elements of the unit in a pro
tected manner so that they will not become dam—
aged or rendered inoperative when transported
from one place to another.
‘The carryingv case illustrated in Figures 1,
3 and .6 of the drawings comprises a rectan
gular housing in having a horizontally hinged'
panel II at one end thereof and a comparatively
deep cover l2 which is adapted to be secured
upon and form a closure for the top of the hous
ing in. Disposed across the top of the hous
ing l0 ‘there is a panel l3 which supports a
tone arm carrying pedestal i4 and a cooperat
ing sound record support. The sound record sup
port comprises an upwardly projecting vertically
disposed shaft I5 having a sound record sup
porting platen l6 thereupon. A tone arm I]
is pivotally mounted upon the pedestal It in

The loud speaker 2| is shown mounted over a
sound opening which is preferably formed in one
of the sides of the housing I0 so that the sound '
emanating therefrom will be directed toward the
15 audience when the apparatus is set up at one
side of a room, as would be the case Where the
apparatus is to be used for the instruction and/or
amusement of a small audience. In a preferred
arrangement of this aspect of the present inven
tion the loud speaker 2| is demountably sup
ported upon the side of the carrying case so that
it may be removed and mounted upon a suitable
baiiie, which can be placed at any convenient
point remote from the apparatus, as for instance,
adjacent the picture screen in front of the
audience. Such a mounting forms the subject
matter of a co-pending application for patent,
Serial Number 22,887, ?led May 22, 1935, by J. L.
Freisner and myself, as joint inventors.
As illustrated in Figure 1 of the drawings, the
platen supporting shaft I5 projects up through
the panel I3 and is driven by an electric motor
mechanism 22 secured to the underside of the
panel I3. A controlling lever 23 by means of
o: Ur which the speed of the shaft I5 may be deter
mined, projects upwardly through the panel I3
and is disposed at a point adjacent the periphery
of the record supporting platen I6 where it can
be conveniently operated. Adjacent the lever 23
40 there is also an operating knob 24 for controlling
In operation the ?lm passes before
tainer. Four of these containers, designated by
the numeral 32, are shown as ?xed to the in
side of the cover I2.
In order that the ?lm may progress freely
through the advancing mechanism 29, it is»
passed through a slot 33 formed in the hinged
panel II. The projection of the ?lm through
the slot 33 permits it to hang free of the ap
paratus where it cannot become entangled there
with or curl up in front of the lens system 21
and interfere with the projection of subsequent 20
Should the sound record I9 relate to a lecture
or a sales talk, which is to be illustrated by pie
tures arranged in a proper sequence upon the
picture film, it is intended that the record will be 25
provided with a sound signal which will indicate
when the picture film is to be advanced. In
practice it has been found that a musical note
interspersed with the spoken program may be
resorted to for this purpose.
Instead of the still picture projecting appara
tus, described above, the panel II may be pro
vided with a moving picture projecting machine.
In this latter event it will be possible to reproduce
synchronized action pictures and sound by start
ing the picture ?lm and sound record at the prop
er synchronizing points.

tion, the weight of the picture projecting appara
tus secured thereupon will operate, because of its 40

The picture projecting apparatus is mounted
60 upon the inside of the panel II so that when it
is closed this apparatus will be concealed within
the housing II]. To provide for a variation in the
angle of projection and to determine the eleva
tion at which the picture is to be reproduced,
65 upon a wall or screen, the panel II is provided
with one or two adjustable brackets 30 which
may be secured by thumb screws 3| to hold the
panel I I at any desired angle with respect to the
housing II). The picture record contemplated for

removed from the shaft I5 and placed, together with one or more records, in a vertical compart~
ment 35 provided at one side of the housing III.
After the sound record supporting platen I6 has
been placed in the compartment 35 the cover I2
can be closed upon the housing I0, as illustrated 60
in Figure 2 of the drawings, where it can be
secured in its closed position by two oppositely >
placed spring clasps 36. The cover I2 also has
a suitable grip or handle 31 on the top thereof,
by means of which the carrying case may be 65
easily handled.
Before proceeding with a description of the
picture ?lm advancing mechanism, attention is
directed to the lamp enclosing housing of the
lantern 26, at the bottom of which there is pro 70
vided a ?ue 38 through which air may enter and
circulate up through the housing; This ?ue 38
may stop short of the hinged panel II or it may
be extended therethrough, as desired. In a modi
?cation of this feature, the hinged panel II may, 75
2,121,010 '
as shown in Figure 3 of the drawings, be pro
vided with a screened opening 88, through which
a circulation of air may pass upwardly through
and about the lamp housing‘ of the lantern 28.
As shown in Figure 3 of the drawings, the ?lm
trated the details of a preferred formvof ?lm ad
vancing mechanism. As shown, this mechanism
comprises a pair of spaced ?lm engaging sprockets
advancing mechanism 28 is adapted to be oper
ated by a pull cord 40, which terminates upon
one arm of a bell crank 4|. The free end of the
bell crank 4| is provided with a thumb rest 42'
6| mounted upon a hub 62. The hub 62 is splined
to an- axially movable shaft 63 so that the sprock
ets 8| may be rotated any desired degree by means
of a knob 64 carried at the end thereof. The
sprockets BI and the shaft 63 are mounted in
a suitable metal housing 65 and the teeth of
the sprockets 6| project through and engage the 10
10 upon which pressure may be applied to operate
sprocket apertures of a ?lm as it passes through
' ing upon the thumb rest 42. The bell crank 4| is
63 and is so constructed that the rachet 66 will
be released from the shaft 63 when the shaft is
in its outermost position. This will permit a
the advancing mechanism 28 through the pull ' the ?lm guiding frame. Mounted freely upon the
cord 48. With this arrangement it will be seen shaft 63 and within the housing 65 there is a four
that the operator may, when standing at the rear point rachet 86 which is held in frictional driv
of the projection apparatus and adjacent the ing' engagement with the shaft 63 by means of 15
15 carrying case, advance the film by simply press-l a spring 61. The spring 61 is secured to the shaft
so mounted that it may be rotated into the car
rying case l0 and concealed by a hinged door
which, when open, provides access to this end
20 of the carrying case. In the event that through
necessity, or convenience, the operator should de
sire to seat himself at the rear of the room re
mote from the apparatus, he can by simply at
taching an extension cord 43 to the bell crank
25 4|, as shown, operate the ?lm advancing mecha
nism from any distance, depending upon the
length of the extension cord 43 so provided. Co
operating with the bell crank 4| there is also
provided a suitable clip_44 which will serve to
30 retain the bell crank in a retracted position within
the carrying case l8.
As illustrated in Figure 4 of the drawings, the
?lm advancing mechanism 29 ‘comprises a rachet
wheel 45 which is connected to a pair of spaced
35 ?lm advancing sprockets by means of a shaft
46. Mounted freely upon a shaft 46 and biased
outwardly by a spring 41 is a lever 48 and piv
otally mounted upon the lever 48 there is a rachet
engaging pawl 48 that is biased by means of a
spring 50 into engagement with the ratchet wheel
45. The lever 48, when in‘its outermost position,
engages a stop 5| carried by a suitable bracket
52. The length and range of movement of the
lever 48 is such that upon a full movement there
of, the picture ?lm will be moved a distance
corresponding to one picture frame. In order to
permit on operation of the ?lm advancing mecha-v
nism. as for instance in framing the ?rst picture,
the shaft 46 is provided with an operating knob
53, such as is illustrated in Figure 5 of the draw
50 ings. In framing a picture in this manner, the
pawl 48 may, if necessary, be disengaged from the
rachet wheel 45 to permit a backward movement ,
of‘ the picture ?lm.
In Figures 6, 7 and 8 of the drawings, there is
shown a modi?ed form of the’ ?lm advancing
mechanism. As here illustrated, the operating
lever 48 is connected through a pin 54 and a
slotted link 55 with a slidabie rod 56 that is
framing of the picture without displacing the 20
rachet 66 from its operative relation to the oper
ating pawl 68. Journaled upon the side of the
housing 65 and adjacent the rachet 66, is a
rotatable plate 88 to which the operating lever
48 is connected. The plate 68 carries a pawl 68 as
that is adapted to cooperate with the four teeth
vof the rachet 68 and move the same one-quarter
of a revolution each time the operating lever
48 is actuated in the manner above described.
In this arrangement a spiral spring 1.8 serves to 30
return the operating lever 48 and the pawl car-.
rying plate 68 back to their initial starting posi
tions. Upon the rachet 6B, and adjacent the
teeth thereof, is a squared portion ‘|| upon whichv
a pressure spring 12 is adapted to rest. The func 35
tion of the spring 12 is to insure a full quarter
revolution of the sprocket wheels 6| and in this
connection the spring 12 operates to carry the
rachet wheel 66 into its ?nal position and retain
it there while the lever 48 and the pawl 68 are 40
retracted into position for a subsequent advance
of the picture ?lm.
60 mounted upon spaced bearings 51 adjacent the
lantern housing.' The slidabie rod 58 is biased
to an outward position by the spring which re
turns the lever 48, and at its rear end it is con
nected through a short length of pull chain 58
with a second slidably mounted rod58 that ex
tends through to the'rear door of the carrying
case I8. The rod 58 is here illustrated as slidably
supported upon spaced supports 60.
It will be evident that with the above and the
previously described arrangement, the film ad
vancing mechanism may be successfully and ef-v
fectively operated when the lantern is positioned
at any of its normal picture projecting angular
In Figures '7 and 8 of the drawings, there is illus
In Figure 9 of the drawings there is shown a
further modi?ed form of ?lm advancing mech
anism wherein there is provided a permanently 45
connected linkage through which- movement is
imparted to the ?lm advancing sprockets from a
position at the rear of the carrying case. As here
shown the ?lm sprocket operating lever 48 car
ries a ?oating link 13 which ‘connects with the -
lower end of a pivotally mounted lever 14. The
lever ‘I4 is pivoted upon a pin 15 and intermedi
ate its ends there is connected a second floating
lever 16 that extends rearwardly through the car
rying case Ill. The rear end of the ?oating link ‘I6 is pivotally connected to a lever ‘I8 which is
pivoted at its lower end uponva pin 19.
mounted upon the pin '18 there is a rotatable disc ,
88 which carries a thumb rest 8|. The disc 88
also carries a pin 82 that is positioned to engage 60
the lever 18 and move it rearwardly when a down
ward pressure is exerted upon the thumb rest 8|.
The pin 82 merely engages the side of the lever
18 and as a result it is possible to rotate the disc
88 clockwise a distance sufficient to permit the
thumb rest 8| to be: enclosed within the carrying
case when the rear, door, designated by the nu
‘meral 83, is closed. In this arrangement the lan
tern supporting panel II is mounted upon sup
porting pivots 84 so that it may be rotated in a
counter-clockwise direction to close the front end
of the carrying case and support the lantern 26
in a concealed position. The supporting panel
|| here shown is constructed of metal and it has
oppositely disposed upwardly extending brackets
85 which engage the pins ‘I5 at each side of the
carrying case opening and support the panel II
in a substantially horizontal position.
In apparatus of this character, it is sometimes
desirable to remove the lantern 26 and therefore
the ?oating link ‘I3 is provided with a keyhole slot
86 which permits a detachment thereof from the
film operating lever 48.
The lantern in this in
stance is shown as secured upon the supporting
panel II by means of removable thumbs-crews 81
located on opposite sides of the lantern. In this
embodiment of the invention, the ?lm support
28 is shown as provided with a ?lmretaining lever
80, which may be lifted to permit insertion of
15 a roll of ?lm and which, when down as shown,
will serve to retain the roll of ?lm in the sup
port. As a further improvement the ampli?er
volume control knob 24 and the phonograph con
trolling toggle switch 25 are shown as mounted
20 upon a panel 89 located at the rear of the carry
ing case adjacent the ?lm advancing thumb rest
8| ..
With the above arrangement of linkage it will
be seen that the lantern 26 may be rotated back
25 into its concealed position without disturbing the
connections of the linkage mechanism as the
lever 14 will float about its pivot ‘I5 and the lever
‘I8 will rotate 'freely about'its pivot ‘I9 and per
mit the mechanism to assume the position illus-'
30 trated by dot and dash lines.
In Figures 10 and 11 of the drawings there is
shown in detail a further modi?ed form of ?lm
advancing mechanism with which there is associ
ated a ?lm holding means that serves to surface
35 the ?lm upon the framing aperture of the lens
system of the projection lantern. As here shown
the ?lm engaging sprockets designated by the nu
meral 90 are mounted horizontally in the hous
ing 65 and associated therewith is a rachet 9I
40 with which a pawl 92 is adapted to cooperate.
The pawl 92 is carried by a plate 93 which is con
nected with the operating lever 48. The pawl 92
is biased into engagement with the rachet 9| by
means of a spring 94, and when the operating
45 lever 48 is operated upon by the ?oating link ‘I3,
the rachet 9| will be turned one-quarter of a
revolution and thus advance the ?lm one full
picture. In order to insure a full and complete
one-quarter turn of the rachet 9|, there is associ
50 ated therewith a pressure bar 95 which is biased
about avpivot shaft 96 by a tension spring 91.
The teeth upon the rachet 9| are so disposed and
shaped that they will provide a series of right
angle surfaces upon the face of the rachet
against which the pressure bar 95 may rest.
At its inner end the rachet 9| is provided with a
cam forming extension 98 against which one arm
of a yoke 99 is yieldingly held by means of a
spring I00. ‘The arms of the yoke 99 are pivoted
60 at their lower ends upon the pivot shaft 96 and at
its upper end the yoke 99 carries upwardly ex
tending arms IOI which carry a pressure exerting
glass I02 that is adapted to engage the ?lm as it
passes through the framing housing and there
65 hold the ?lm ?rmly and smoothly in the framing
aperture. The glass I02 is mounted in a suitable
_ frame I03 which carries rearwardly projecting
pins I04 that engage the arms IOI. To provide
for a yielding pressure by the glass I02 there is
interposed between the arms IM and the frame
I03 a pair of compression springs I05. A spring
I09 is here shown for returning the plate 93 with
the pawl 92 to their initial position.
With this arrangement it will be readily seen
75 that as the pawl 92 operates to turn the rachet
9| and advance the‘ ?lm, the cam surface 98 will
also rotate and by virtue of its'contour cause the
yoke 99 to rotate outwardly about the pivot shaft
96 andflift the pressure producing glass I02 out
of engagement with the ?lm and permit its free
movement through the framing mechanism. 1 It
will also be seen that when the operating lever is
rotated through a full ?lm advancing movement
the pressure bar 95 will move outwardly and ex
tend its tension spring 91 until a maximum out 10
ward position is assumed, after which the pres
sure bar 95 will move inwardly under the in
?uence of the spring 91 and assist in turning
the rachet 9| into a subsequent ?lm framing po
Upon referring to Figure 12 of the drawings it
will be seen that the lantern supporting panel II
is adapted to come to rest when the brackets 85
at each side thereof come into engagement with
the pins 15. When ‘the projection lantern is se 20
cured upon the supporting panel I I, as illustrated
in Figure 9 of the drawings, the picture screen -
will need to be adjusted in elevation to suit the
projection angle of the lantern. To remedy this
the lantern is shown, in Figure 12 of the draw 25
ings, as provided with rearwardly projecting arms
I0‘I which are pivotally secured upon the pivot
points 84 about which the supporting panel II
Beneath the lantern and in an outwardly
disposed position there is a suitable lantern ele 30
vating device by means of which the lantern may
be elevated through a limited vertical arc inde
pendently of the supporting panel II. This ele
vating device, in its preferred form, comprises a
cup-like member I08 which is rotatably mounted
upon the supporting panel II. The cup-like
member I08 has an operating lever. I09 and in
oppositely disposed positions it is provided with
spirally disposed slots I I0 into which project op
positely disposed pins III located upon the bot 40
tom of the lantern 26. The inclination and
pitch of the spirally disposed slots IIO-are such
that when the lever I09 is pulled outwardly from
the lantern the pins I I I will ride upwardly in the
slots H0 and thus elevate 'the front of the pro 45
jection lantern 26. In order to hold the lan
tern 26 against the supporting panel II when
the carrying case is closed, the spiral slots II 0
are provided with a short ?at portion “2 at the
lower ends thereof.
From the above description it will be seen that
I have provided a convenient and novel form of
combined carrying case and a lantern supporting
means in which the angular projection of the
lantern may be adjusted to any suitable angle
without at the same time disturbing the level of
the sound record platen which, as is well known,
should operate on a substantially level plane in
order to secure proper cooperation with the deli
cately balanced electromagnetic pick-up device 60
such as is commonly used with apparatus of this
character. Another novel feature of the present
invention is that the picture advancing mecha
nism can be operated whilethe lantern is in any
of its normal angular positions without requiring 65
any adjustments between the ?lm advancing
means and the operating means at the rear of the
carrying case, and that the hinged panel I I which
supports the picture projecting lantern can be
freely opened and closed without requiring any 70
detachment of the operating mechanism. An
other important advantage in the arrangement
of my present invention is the provision of a com
bined carrying case and lantern support wherein
the lantern may be conveniently moved and ex 75
' peditiously adjusted in an operative position externally of the carrying case where a natural.cir-,
culation of cooling air will exist when the lantern
is in operation.

order to disclose my invention so that the same
can be readily understood, described and illus
trated speci?c devices and arrangements, I de
sire to have it understood that this invention is
