10 Claims.

jected by apparatus within the cabinet and 'sov constructed that the'screen can be extended from the cabinet into a display position but which, when not in use, will occupy a folded position within the body of the cabinet.

The invention is 'intended particularly for use in connection with the means patented to me December -19, 1933, in my prior Patent No. 1,940,148, on Projecting apparatus.

My prior patent covers projecting apparatus to be used for displaying scenes from attractions now showing in moving picture theatres, and attractions which are coming in the near future to the same theatre, and one of the objects of the present invention is to provide a cabinet particularly adapted to cooperate with the projecting apparatus covered by the said patent;

also to provide a cabinet of this kind which will normally house the projection screen within the cabinet but which can be readily operated so as .to extend the screen into a display position.

A further object of the invention is to provide a cabinetof this kind which will be compact and provided with reectois arranged in such I a way that a screen of relatively large size may be employed although the cabinet will occupy relatively small floor space.

A further objet-,ofi'this invention is to produce a cabinet of this type capable of Ibeing used for displaying moving pictures or other pictures particularly adapted to be used for advertising purposesin va foyer or in area in front of a theatre, andv to construct the cabinet in such a way that when notin use it can be folded into a relatively compact space so that it will be capable of being trundled through the doo'r of the theatre or other building. at which it is used.

, A further object of the invention is to provide' special means for excluding light from the interior of the cabinet immediately to the rear ofv.

thescreen; also to provide means for excluding side lights from falling on the front of the screen. Further objects of the invention will appear hereinafter. a

The invention consists in the novel parts and combinations of parts to be described hereinafter. all of which contribute to produce an emcient l picture display cabinet.'

"A preferred embodiment og the invention is `described inthe following Specification, while the broad scope of the 'invention-is in the appendedclaims.

In the drawings:

Figure 1 is a perspective of a cabinet embodying my invention and representing the same in its folded or closed condition.

pointed out Figure 2 is a perspective of the cabinet illusthe plane of the line 4-4 of Figure 2 and illustrating the relation of the parts when the cabinet is in its open or extended position for the screen.

Figure 5 is a horizontal section on Fig. 4 about on the line 5-5 upon an enlarged scale, certain parts being broken away, and further illustrating details of the means for extending andre-- tracting the screen and also details of the mounting for the screen.

Figure 6 is a vertical section taken about on the.line E-/-S of Figure 4ffurther illustrating details of the construction.

Referring more particularly to the parts, I in- 30 dicates the body of the cabinet which is of box form, preferably having a substantially vertical front wall 2.

The cabinet includes a' screen carriage 3 (see Figure 2) which is of substantially box form havinga cover plate 4 and side walls 5. This carriage is mounted for sliding movement in or out of the cabinet and preferably'inY an upwardv direction so that the screen 6 mounted on the carriage will be in an elevated position for displaying the pictures on the screen. In other lwords, Figure 2 represents the screen in its dis play position. Any suitable means may beeinployed for-extending and retracting the screen carriage, but in the present instance this is acprenant' instance it ls illustrated as mounted on u Y ent instance it is mounted on the underside of a plate I which in the folded condition of the cabinet operates as a cover for a portion of the cabinet and cooperates with the top plate or cover ,plate -4 of the carriage 3 to form a substantially continuous cover for a considerable portion of the cabinet.

The plate I5 may be considered as a reector frame and in the present instance this plate is connected to the cabinet body and to the carriage 3, being hingedly connected to one of these members and slidably connected to the other. In' the present instance the plate I5 is connected byy a hinge joint IB to the forward edge of 4a xed cover plate I1 which covers the rear end of the cabinet. The forward end of the plate I5 and reflector I4 extend into the rear side of the screen carriage 3 which is open, and at each side the plate I5 is provided with a hanger or bracket I8 having 'a pin I9 running in a slot 20 formed in a guide bar 2 I. These guide bars 2I are located directly under the coverl plate 4 of the carriage 3.

In order to exclude the light from coming in at yeach side l of the reflector plate I5 when in its extended position as indicated in Figure 4, I provide side plates 22 integral with the plate I5, and

these side plates 22 are preferably of sector form with arcuate outer edges 23.

At the back of the carriage 3 at au elevated point and just back of the upper end of the plate I5 where it projects into the carriage, means is provided for excluding the light, preferably in the form of a flexible flap 24 which if desired may have a horizontal hinge connection 25 permitting it to`l swing into a substantially horizontal position when the cabinet is folded up as indicated in Figure 1.

In the present construction, when ,the side plates 5 of the carriage 3 descend, they are sutW stantially in linewith the hubs 8* of the pinion-1s l, and hence it is necessary to provide clearance slots 25 which extend vertically upwards inthe side walls 5 from their lower edges. These slots enable the side plates 5 to pass down over the hubs 3*. However, in the elevated position of the carriage these slots would admit light and hence in the construction illustrated it is necessary to provide a shutter 21 at each side to cover these slots in the elevated position of the carriage. Each of these shutters 21 is preferably in the form of an elongated flat-plate or bar pivotally supported on a pin )2l on the inside of its corresponding side plate 5; `and a spring, which may be in the form-of a coil spring 29 may be provided for urging each of these shutters* 21 forwardly at its lower end. The lower end kvof each shutter 21 is formed with an inclined cam edge 30. When the carriage descends, this cam edge 30 strikes the corresponding hub l* and this swings the shutter to one side on its pivot pin 20. e

'Ihe rear portion of the interior of the cabinet body constitutes a projection compartment 3i which is divided of! from the remainder of the v interior of the cabinet by a division wall 32 which -is disposed in a general vertical direction. The

lower portion of this wall 32 may be a fixed plate 33 through which an opening 34 is formed for the, passage of the light rays that project-,otite image to be thrown on the screen 6. However,v ,the` upper portion 35 of this division wall 32 is prefer` ably mounted so that it is movable in a forward direction so as to allow clearance for opening the cover 35 of the projection apparatus 31 which stands in the projection compartment 3|. I'hls projection apparatus 31 is of the type illustrated in my patent referred to above; and in inserting the continuous film in the film magazine 38, it is necessary to open the door 36, swinging the same outwardly onits hinge 39. Bymaking the upper v v portion 35 of the division wall movable, this part of the wall can be swung forwardly as indicated by the dotted lines in Figure 4. In order to accomplish this, the movable part 35 is preferably made of two-

hinged sections

35 and 35, the upper section 35s having a hinge connection 40 attaching it to the underside of the cover plate Il, and the lower edge of the section 35 being connected by a. hinge 4I with the section 35i. Detachable hooks 35c attached'by springs 35d are provided for holding the lower edge of the section `35i against the forward side of the upper edge of the fixed wall section 33. A soft pad strip 33 may be provided as shown to make this joint light-proof. d g

If desired means may -be provided for latching the movable `rportion 35 in its extended position so that it projects forwardly from the projection compartment 3|. For this purpose I may provide a latch bar 42 mounted on a pivot pin 43 under the cover plate I1 and capabley of being swung around so that the tongue 42Il formed at the end of this latch can 'engage the upper section 35* of the division-walll as indicated in dotted lines in Figure 4.

Within the forward portion of the cabinet I provide a primary reflector 44 from which the image is projected from the lens of the projection machine located at 45, and the image thrown onto this primary reflctor is reflected up onto the reflector I4; which may be considered a secondary reflector from which the light is reflected onto the rear of the screen 5 to produce the image visible from the front. The dotted lines 48 indicate the limits of the beam of light that forms the image.

In practice the reflectors I4 and 44 are parallel, or nearly so, and in order to provide for adjusting their relation to insure proper register for the picture on the screen, the reflector 44 is prefer-y -ably mounted for adjustment on a substantially horizontal pivot pin 41 whichmay be supported on a suitable stand 43. The projection compartment 3| is accessible at the rear of the cabinet through a hinged door 43,

and in order to enable the attendant toascertain whether the picture is properly cast on the screen 3, I provide the upper section 35# of the division wall 32 with one'or more peep holes 50 see. Figure 3) which have movable covers or shutters i 5I pivoted at 52.

The cabinet is preferably-provided with means for supporting the side edges of the reflector plate I 5 when in its horizontal or folded condition. This tends to prevent buckling of Nthis plate which might strain the vreflector I/4-if. the same were a order to exclude the light and also to prevent the flange 54 from scratching the side plate 22, I provide the flange 54 with a flexible packing strip 56.

This packing strip may be of folded felt or any other suitable material. At other points throughout the cabinet where there is any possibility of light entering, I provide packing strips of felt or similar material.

rI'he cover wall I1 is preferably provided with Ventilating openings 51 f see Figures 1 and 4).

In order to exclude side lights from the forward side ofthe screen which might interfere with the clearness of the picture, I prefer to provide a hood 58 which is preferably constructed as indicated in Figure 4. In other words, this hood is foldable or removable and preferably comprises an upper plate 59 connected by a hinge connection 60 to the forward edge of the cover plate 4 of the carriage, and in the open position of this hood the plate 59 is supported on two side plates 6| which have v hinge connections t2 on the carriage 3 at the front. When it is desired to fold up the hood 58 when the carriage 3 is to be retracted into the cabinet body, the two side plates or panels 6l are swung inwardly on their hinges 62 andthe plate 58 is then swung downwardly, and if desired, small pivoted latches 63 may be provided for latching over the side edges of the plate 59 to hold it down'.

In the folded position of the cabinet it will b e evident that the brackets I8 will hold the forward end of the plate l in a slightly depressed position, and hence the supporting flange 54 (see Figure 4) should extend in an inclined direction, being depressed toward its forward end. This flange 54 may be formed as an extension on a cornice 64 hung over an angle iron 65 which is a frame member for supporting the side plate 55 (see Figure 6).

In case itv is desired to employ a loud speaker with the picture projection apparatus, the forward wall of the cabinet should be provided with an opening preferably provided with a screen 66 (see Figures l and 4), at which the loud speaker 61 is located. Back of this loud speaker` a box 68 may be provided for amplifying apparatus connected by a cable 69 to the interior of the projection apparatus 31 where proper electrical connections would be made with sound translating apparatus (not illustrated).

The screen 6 may be'mounted in any suitable manner, but as illustrated in Figure 5, it may be mounted in a suitable frame 10 in such a way that the screen can be placed in tension. For this purpose the edges of the screen would be provided with rods 1| connected by elastic bands 12 with pins or screws 13 at the outer edge of the screen frame.

On the forward side of the forward wall of the cabinet I prefer to provide a sign 14 which would cooperate with the projection apparatus 31 in the manner described in my prior patent, that is to say, this sign 1d would have two

legends

15 and 16 preferably formed in neon lights and these legends would be switched on alternately, controlled automatically to synchronize with the character of the pictures being thrown on the screen. In other words, if the pictures thrown onto the screen illustrate scenes from a playshowing in the theatre at the time, the legend Now showing would be lighted, and vice versa.

The cabinet illustrated is mounted onv caster wheels that facilitate its being moved in and out through the doorway of a building such as a theatre.

The wrench I3 is a socket wrench, and is removed after using it. A disconnectible electric cord la (see Fig. 1) is employed for supplying the apparatus with electric current.

For safety against flre, the projecbion machine 31 is preferably constructed in accordance with my prior Patent No. 2,008,878, dated July 23, 1935, which discloses a construction for automatically stopping the water and shutting off the light circuit in case the film should become broken.

The magazine 38 is preferably constructed in accordance with my Patent No. 21120521, entitled Projecting apparatus", dated November l2, 1935.
