Fig. 8 is a perspective view of the pick-up arm supporting member illustrated in Figs. 2 and '7.
As illustrated in the accompanying drawings, the'present invention comprises a container or casing indicated, as a whole, by the numeral ll having a cover member l2 operatively related ,and adapted to be removably connected thereto by means of cooperating hinge connections 13 and cooperating locking means l4 (Figs. 1, 2, and 4).
Mounted in the casing H is a plate 15 adapted to cover a substantial portion of two sides of the casing and spaced from the bottom portion thereof as clearly illustrated in Figs. 1 and 4, and mounted alsoin the casing ll, preferably, adjacent one corner thereof and .beneath the plate i5 is the motor 16 having a rotating spindle l'l operatively related thereto and adapted to receive a turn-table Ila on which sound-records of various sizes indicated at l8 and 18a (Fig. 4) may be mounted, the motor Hibeing connected through a switch l9 and suitable electrical conductors 2| and 22 (Fig. 2), with a suitable source of electrical current supply for actuating the motor and rotating the turn-table sound-record l8.
-Mounted on the plate I5 is a pedestal 23 on which is pivotally mounted a tone or pick-up arm 24 having a needle 25 mounted thereon adapted to cooperate with sound grooves formed in the record l8, as is common practice in reproducing machines, the tone or pick-up arm 24 being shown in present instance as operatively connected by means shown at 26 (Fig. 2) with a sound amplifying device 21 operatively connected by means ofa conductor 28 with a loud speaker unit 2! having a speaker cone 3| associated therewith mounted on and secured to the inside Ila and of the plate l5 by means of screws 32, the plate being perforated or provided with a plurality of apertures 33 adjacent the speaker unit 29 and cone 3| for permitting the passage of sound therethrough, while the amplifier 2! is operatively connected to the switch l8 by means of a conductor 34 by which the operation of the am plifier and the speaker unit may be controlled.
By such an arrangement it will be apparent that the sound picked up from the record 18 by the needle and arm 24 may be amplified and transmitted through the amplifier 21 to the loud speaker unit 29.
Mounted also in the casing H and hingedly connected thereto, as indicated at 35, is a projector indicated as a whole by the numeral 36, operatively connected to an electrical conductor 31, switch 38 mounted on the plate l5, and conductors 39 and 22 with the source of current supply employed for operating the motor 16 and amplifier 21. g
The projector 36 is shown in Fig. 1 in upright or operative position for projecting a picture or the like onto a screen 41 mounted on a partition 42, formed preferably of heat insulating material, hingedly connected by means of hinges 43 to and within the cover member [2 in, spaced relation to the closed side thereof, as clearly shown in Fig. 4 of the drawings, the projector 36 being provided with a film holder 44 adapted to receive a roll of film 45, which may be fed through the projector by means of the sprocket wheel 46 operated by a hand wheel 41 and past a light beam generated by a lamp 48 mounted in the projector, the
film being fed downwardly into a film receptacle 49 formed in the casing I I, said receptacle having, preferably, an inclined or curved portion 5| ad jacent one of its sides to facilitate the re-rolling of the film within the receptacle.
As illustrated in Figs. 2" and 4, and shown by dotted lines in Fig. 5, the projector 36 is adapted to be swung about its hinge connection into a folded or inoperative position with respect to the casing l l and is adapted to be secured thereto in such folded or inoperative position by means of a button 52 pivotally mounted on a stud 53,
the form. and position of the button 52 with respect to the edge or wall'portion of the casin H being such that when the button is out of projector securing position, as illustrated in Fig. 1,
the button will interfere with the positioning of the cover member I 2 on the casing, but. when moved to the position shown in Figs. 2. and 4 for securing the projector in inoperative or folded position with respect to the casing II, the cover member l2 may be readily positioned thereon for closing the open side of the casing H as shown in Fig. 4.
For protecting the filament of the lamp 48 of the projector 36 against possible damage by reason of the current being connected with the lamp when the projector is in folded or inoperative position, the projector 36 and bottom plate 54 thereof are mounted on a base member 55 to which the hinges35 are connected for pivotally securing the projector to the casing H through the medium of a support 56 forming a part of the casing (Figs. 5 and 6), and mounted on the base 55 in a manner to move therewith is a resiliept contact finger 5T operatively connected through a conductor 58 with the lamp 48, and mounted on the support 56 is a resilient contact finger 59 adapted to cooperate with the finger 51 when the projector is in upright operative position, and to be separated therefrom when the 7 projector is moved to andretained in inoperative or folded position with respect to the'casing, the lamp 48 being provided with a conductor 6!, and the spring finger 59 being operatively related through a conductor 52 to a junction box 63 in which suitable connections are made with the conductor 37 for controlling the operation of the projector lamp by manipulation of the switch 38 when the projector is in upright operative position as shown in Figs. 5 and 6. It will be noted by reference to Fig. 5 that the projector 35 may be maintained in upright operative position by means of a spring latch 64 mounted on the support 56 and engageable with the upper side of the base of the projector.
By reference to Fig. 6, it will be noted that the bottom plate 54 of the projector 36 is secured to the base 55 by means of a bolt 65 having a spring 66 operatively related thereto and to the plate 54 for yieldingly or movably securing the plate 54 adjacr..t one of its ends to the base 55, and for raising and lowering the opposite end of the plate 54 for elevating and lowering the beam of the projector. an adjusting screw 61 threaded into a ring or plate 68 mounted on the support 56 is adapted to extend through an opening 69 formed in the support 56 and into engagement with the underside of the plate 54, and from this arrangement it will be apparent that by manipulating the adjusting screw 61, the adjacent end of the plate 54 may be raised and lowered against action of the spring 66 in a manner to vary the elevation and angle of the beam of the projector in a manner to properly position an image on the screen 4| in the event of unevenness in the surface on which the casing l I and cover member l2 may be positioned when the device is set up for operation.
For conveniently supporting and carrying the records I8 used in the operation of the device. the
\ closed side of the cover member I2 is provided with an inwardly extending spindle H adapted to enter the centering apertures of the records [8 in a manner to support the records thereon, after which the turn-table Ha. may be positioned on the spindle H and the turn-table and records may be rigidly secured to the cover member l2 by means of a nut '12, as clearly illustrated in Fig. 4, and by reference to Figs. 3 and 4. it will be noted that the respective corner portions of the cover member l2 are provided with loops 13 for holding a plurality of rolls of film 45 or containers therefor.
It is 01 well known fact that considerable heat is generated by the lamp 48 of the projector, and that such heat is frequently retained for a considerable period of time by the lamp housing and other elements of the projector, and in order to protect the records and films from such heat when placed in the closed casing, as shown in Fig. 4, the partition 42 on which the screen 4| is mounted is positioned in th cover member l2 in spaced relation to the closed side thereof and between the films and records mounted on the cover and the projector, the partition 42 being shown, in the present instance, as secured in position by means of a latch," pivotally mounted on the partition 42 and engageable with a portion of the cover member.
For securing the tone or pick-up arm 24 in fixed position with respect to the casing II when the device is packed for transporting, the arm 24 is provided with a supporting member indicated, as a whole, by the numeral.'l5 pivotally mounted adjacent one of its nds at 16 to the arm 24 and provided at its opposite or lower end with a laterally extending foot portion 11 having a recess 18 formed therein adapted to receive a stud shown, in the present instance, as a screw 19 mounted on the plate IS, the member 15 being adapted to be retained in operative position with respect to the stud 19 by means of a spring 8i mounted on the arm 24 and acting to yieldingly urge the supporting member 15 toward the stud and to move the supporting member to the dotted line position shown in Fig. 7 when the member is disconnected from the stud. For conveniently manipulating the supporting member 15 to operative and inoperative position, the member is provided with a finger piece 82 adapted to extend laterally at one side of the pick-up arm 24, as shown in Fig. 2, in a manner to engage the underside of the arm and serve as a stop against upward movement with respect to the arm.
From the foregoing description, it will be apparent that th present invention provides a novel construction and arrangement whereby the elements of a sound-picture machine of the character described may be positioned conveniently in folded compact relationship for safe transportation and handling of the device, and wherein the elements are conveniently accessible for setting up the device in operative position.
It will be observed also that the present invention provides novel means for protecting the filament of the projector against breakage or damage when setting up or dismantling the device, and that suitable provision is made for protecting sound-records and films employed in the operation of the devic against the heat generated by the projector, thereby preventing warping or other damage to the record, discs and films.
Obviously, the present invention is not limited to the precise construction and arrangement shown and described, as the same may be variously modified. Moreover, all the features need not be used conjointly, as the same may be used to advantage in variously different combinations and sub-combinations.
