Our-invention relatesito acousto cinematographic apparatus and ha's particular graphic m ication, to portable, acousto-cinematograp 1c apparatus. f f q Thefield of usefulness of portable talkmg motion-picture apparatus is extremely Such apparatus may, of course, be utilized for amusement purposes in homes and mlo calities where the apparatusof the ordina' type is not available. cation of the apparatus constitutes only a restricted region of its wide field of utility.

The apparatus may be used for advertising purposes: In certain nstances it may go so far as to supplant theordinary salesman in giving a sales talk. Thus, a portable equipment may beshipped to the executives ofa firm in a foreign country. Amongthe film rollsfshipped with the machine may included several rolls inwhich are described a group of articles in which the domestic firm is endeavoring to interest the foreign firm.

Another important use of; the apparatus lies in the educational field. Faithful records of important experiments may be recorded with facility. A portable acousto-cinematomachine provides a meanswhereby these records maybe'widely distributed in a sim leand an inexpensivemanner.

Iibvvever, the provision of a-portable talking motion picture machine is not at. all a simple matter. In addition'tolthe machine which is ordinarily comparativel heav and cumbersome,an amplifiena lou spea er, a screen, film rolls anda plurality of filmhandling mechanisms, suchfas reelingdevices and splicrs, must be transported. The provision of'suitable containers for this equipment isa considerable problem. I

It is, accordingly, an. object of ourinvention to provide portable cinesa'coustic equipment. f. v, y nother object of our invention is toprovide acousto cinematographic apparatus so disposed that it may be transported with I facility without being disarranged. I a

p A furtherobjectof our invention is topro vide apparatus for' manually transporting all of the elements necessary in operating a photo-acoustic equipment. v x

More speci cally stated, it is an object of our invention to provide a plurality of .con-

tainers for acousto-cinematographic apparatus that shall beso constructed as to renderthe apparatus useable, after it has been e from one destination to another, within a short time after it arrives at its final destination.

According to our invention, we provide three containers, one container having the acousto-cinematographic machine disposed therein; the second having the electrical amplifying equipment disposed therein, and the third having the remainder of the apparatus necessary in the equipment disposed therein.

The first container is provided with a plurality of openings through. which the (pictureprojecting light beam and the soun -reproducing light eam are transmitted. The second container is adapted to be fastened to the first container in such position, relative to it, that an'opening in its Wall leadin to the photo-sensitive cell coincides with t 0 openm in. the wall of the formerwhich is rolvi ed for projecting the sound exciting hght earn.

the necessary apparatus for fastening the machine, for ad uStin its vertical position and for removing the heat energy generated in the equipment. 7 I r s l The third container has a loud-speaker disposed in one wall thereofand is equipped with a chamber in which a roll screen is fastened. The roll screen may be unrolled from the chamber and held'in a plane substantially the container. The coverof this container may be entirely removed therefrom and have a reeling device a'nd'a support'for a film splicing device secured thereto which, under ordinary circumstances, is carried'on a base disposed within the container. I

The novel features that we consider char- The first container .is also equipped withv pecific object of our invention is in %igure 1 is a view, in perspective, illustrating the disposition of containers, constructed according to our invention, relative to each other, when in operable position;

Fig. 2 is a view, in pers ective, showin the container for the ainpli ying system an the container for the machine, a section bein broken away;

ig. 3 is a view, in perspective, showing the loud-speaker and the screen container with its cover displaced.

The apparatus shown in the drawing comprices a container 1 provided with a plurality of female sockets 3 in which the power-supply leads 5 of the system are adapted to be removably secured, a second container 7 having a bar 11, of transverse L-section, fastened to one of its surfaces 9 which is adapted to engage a second bar 13 of transverse L-section, secured to the first container, and a third container 15 constructed as will be describedhereinafter and independent of the other two.

In the interior of the container 1, a shelf 17 is secured. The shelf 17 separates the container into an upper chamber 19 and a lower chamber 21. A power-supply unit 23 is disposed in the upper compartment 19, and an amplifying unit 25 is disposed in the lower compartment 21 of the container 1. The amplifier 25 is provided with a photo-cell 27, the window 29 of which faces an opening 31 in a wall 33 of the container 1 that coincides with a similar opening 35 in the adjacent wall 9 of the second container 7. The container 1 is equipped with a hinged door 37 that is adapted to be locked in any well-known manner.

- The second container 7 is adapted to support the machine 39, of the type described in a copending application Serial No. 436,552, to E. TV. Reynolds filed March 17, 1930. and assigned to \Vestinghouse Electric & Manufacturing Company, and has a plurality of clamps 41 and 43 disposed therein whereby the machine 39 is held rigidly therein. In Fig. 1, the container 7 is illustrated without the machine 39, for purposes of clarity.

The container 7 is, moreover, equipped with a threaded stud 45 to traverse a boss 47 mounted in the wall 9 and to engage the threads in a boss 49 mounted in the wall 33, of the amplifier container 1, that is adjacent to the wall 9 of the projector container 7. The stud 45 is adapted to be held in its outermost position i by a fiat spring 51 fastened to the interior roll screen 85 secured therein.

When the system is operated, the two con- 61,.communicatin with the opening in, the

hollow bar 57, an engages with the bar 57. The bar 57 is slotted in the region of the arm 61 and, therefore, pinches the rod to hold it fixed. The rod 55 has a knob 63 secured to its lower end, whereby the unit may be su orted in any desirable inclined osition.

he projector container 7 is, furt ermore, equipped with a felt block 65 having a plurality of openings 67 milled therein. The block 65 is fastened in the lower ortion of one wall 69 of the container 7, an its openings 67 coincide with corresponding 0 mngs (not shown) on the side wall 69 of t e container. The perforated block 65 cooperates with a flue 71 projecting from the upper wall 73 of the container 7 to remove the heat energy nerated therein.

The ge lt block 65 provides the necessary sound insulation and prevents the noise of the projecting machine from interfering with the perfomance.

It is to be noted that the problem of the disposition of the heat energy is not an inconsiderable one and requires considerable thought, since the ener generated in the small region by the pro ection lamp and the sound-reproducing lamp of the machine is considerable.

The projector container 7 is provided with a hinged door 75 which is adapted to be locked in a manner similar to that for the door 37 on the container 1.

The third container 15 has a translating device 79, such as a loud-speaker, centrall secured to one of its walls 77 and the wall 7 is, moreover, provided with a cover 81 hinged below the loud-speaker and adapted to be locked over it, when the system is not in use. An elongated chamber 83 of which the wall 77, having the loudeaker 79 secured there in, forms one boun ary, is located in the upper portion of the container 15 and has a The screen 85 may be unrolled from the enclosure 83 and held in a vertical position by a plurality of bars 87 supported in the u perwall of the container 15 and adapted to be carried in its interior. A plurality of brackets 89 are suported on the rear wall 91 of the screen chamr 83 and are capable of supporting the necessary lead wires (not shown).

in the bars 11 and The screen enclosure 83 is adapted to be a suitably locked when the system is not in use.

In the interior of the enclosure 15 is disposed a bar 93 on which a pluralit of film reels 95 may be supported. A bloc 97 fastened to the wall 99 of the enclosure 15, is provided with a suitable system of clamps 101 whereon a film-splicin .device 103 is rigidly held when the system is transported and the splicer 103 is not in use.

One wall 105 of the container 15 is removable and has the elements 107 of a film reeling device secured thereto, and is also pro-I vided with a block 109 which has a plurality of clamps 111 to support the film-splicing device 103 when the apparatus is in use. The removable wall 105 may be securely fastened to the container when the apparatus is transported. It may be mentioned that the. film splicer 103 is adapted to be disposed between the elements 107 of the relay device where it is ordinarily most useful.

The particular arrangement and structure of the containers 1, 7, and 15 described hereinabove lends the apparatus considerable tractability. In transporting the system, the machine and the amplifier may be carried by one man, while a second man carries the loud-speaker, the screen, and the further necessary appurtenances of the system. The system may thus transported from one place to another with considerable speed and facility.
