cording on an endless sound track and means for synchronizing the audible reproduction thereof with the-movement of the door of the vehicle so that the recording or warning is reproduced commencing at the beginning thereof shortly after the opening of the door, is repeated continually duringthe time that the door is open, and upon the. closing of the door the recording will cease after completion of the warning.

The invention also has in view an" annunciator of the indicated character in which the endless sound track is moved with reference to the sound reproducing means at a rateof speed adaptedto obtain clarity of pronunciation-of therecording and in which the sound reproducing means does not become effective until the desired rate of speed of the sound track is attained.

The invention has for another of its purposes the provision of an annunciator for audibly reproducing an advertisement or slogan upon the actuation of the control switch therefor by the deposit of a coin or slug in a vending machine or the like. I

With the foregoing and other objects in View reference is now made to the following specification and accompanying dr'awingsin which the preferred embodiment of the invention is illustrated.

vReferring to the drawings by characters of reference, the device includes an endless film I0 mounted upon rollers H and having sprocket I 4 claims. 01. 179-1003) engaging openings 12 adjacent a longitudinal edge thereof for engagement with a sprocket roller [3 secured to a shaft l4.' The rollers I l are journaled' on trunnions l5 affixed to a suitable support Ni and are arranged in parallel relation with the longitudinal axisof the shaft l4. 7

The film i0 is driven by an electric motor I! through a drive shaft I8 affixed to the armature thereof and' having a worm l9 at its free end whichmes'hes with a gear 20 secured to the shaft i l; .The drive shaft. [8 is mounted for rotation in bearings 2| while the shaft I4 is mounted for rotation in a bearing in the support 16 and in a bearing 22 at the opposite end thereof. o i

The film i0 is formed with a sound track on which is recorded an. announcement; warning or message which is audibly reproduced by any desired means such as a photo-electric cell 24 arranged in juxtaposition to the sound track and connected by conductor wires 25 and 26in an electric circuit with an audio amplifier and speaker 21. The excitor 28 of the photo-electric cell 24 is connected by conductor wires 29 with asource'of current supply and the audio amplifier,

and speaker 21 is also connected with a source of current supply as illustrated by conductor .wires 30. 'A switch 32 is actuated by any desired means such as the opening and closing of a door or other 7 movable object indicated generally by the reference character A in Fig. 4 of the drawings for controlling'the starting of the motor 11.

In order to provide means for putting the photoelectric cell into operation when the film has attained a rate of speed best adapted for clarity of pronunciation of the recording, a governor 33 is provided which is mountedonthe drive shaft I8. and has a normally open switch 34 connected in said electric circuit with the photo-electric cell and which governor functions to close said switch 34 when the desired'rate of speed of the film has been attained. Acam 35 is provided for synchro nizing the beginning and ending of the audible reproduction ofthe recording on the sound track so that the reproduction starts and ceases when the dead or unrecordedportion of the sound track is in juxtaposition to the photo-electric cell. The cam 35 is affixed to one end of a shaft 36 arranged at right angles to the shaft I4 and has a gear 31 aflixed tothe opposite end thereof which is in meshing engagement with a worm 38 'secured to the end of the shaft I 4 The shaft 36 is-revolvablyxmounted so as to disposed the cam in juxtaposition to a switch 39 the free end-of which is engaged by the high portion of the cam 3 for moving said switch in one direction against the tension of springs 4|! which springs function to return the switch to its normal position after release by the cam.

The switch 32 is of the double pole single throw type and has a contact 32a thereof connected to one side of the motor 11 by a, conductor wire dl. The opposite side of the motor is connected through conductor wires 42, 43 and 44 to the other contact 320; of said switch 32. The remaining contacts 32b and 32d of said switch are connected by conductor wires 45 and 46 to conductor wires 4'! and 48 leading to a source of current supply. The conductor wire4s3' is also connected to one side of a solenoid G9, the opposite side of which is connected by a conductor wire 50 to a conductor wire 5% which latter is connected to one side of the normally open switch 3% controlled by the governor 33 and to a conductor wire 52 leading to. a contact 53 of the cam operated switch as and to. a. contact 56a of a switch 55. The opposite contact 54. of said switch 59.- is. connected by a conductor wire 55. to a con-. tact. 5.513. of said switch 55 thereby placing the two sets of: contacts. in parallel. The said switch is normally open and is; closed by the attraction of the. armature 51. to. its. solenoid 58 when the same. is. ene gized The contacts. 53.- and 5.4 of the cam operated switch 35: are normally open and are closed when the, is. engaged and moved by'the high portion' of the cam 35., The solenoid; 58. is. connected by wr ductor Wire: 59 to. the conductor wire 44 whilev the: opposite side oi said solenoid is connected by a conductor wire 50 to the remaining terminal-f the switch 34. carried by the governor 23: cQnnects the solenoids 4:9. and. 5.8; in parallel between the conductor wire- 14 and the conductor Wire 5.55 when the switch 314. is closed y t e overnon. The conductor; wire, 5.9.. is also connected to a conductor wire Balwhich has one hereof; connected to a. contact 62 or saidam ope ated wit h) 3.9:, the oppos t contact. :3 otwhich i,s co nnecte.d: bya conductor wire 6.41 toa. e of. our ant; supplythrough the. conductor contacts. 62; and 63 of said cam: ne edswitch. .9; are nonnallr closed when the seneas dby thelowen portion. of the cam high portion thereof;

Where-tits switch 3.2; is closed any desired 4 means to thereby place in operation the motor H and start the movement of the film l0 and the revolving of the governor 33 and cam 35, the solenoid 49 will be energized when the switch 39 is moved by the high portion of the cam to close the contacts 53 and 54. This results in an intermittent energizing thereof together with an intermittent opening and closing of the switch 68 by the attraction of the armature 6'! to said solenoid until the switch 34 is moved to closed relation by the governor 33 attaining the desired .speed for satisfactory reproduction of the repositions to: the. photo-electric cell 24.

cording on the sound track of the film. When the Switch 3 5 is thus closed by the action of the V governor 33 the solenoid 58 is energized by the closing of the circuit through the conductor wire 45. from the switch 32 to the conductor wire 69 and thence to the conductor wire connected to the contact 54 and then through contact 53 and conductor wire 52 to conductor wire 5| and through the. switch 34 to the conductor wire whlehconnects with one side of the solenoid 58. e qhl osite. side oi the. solenoid 53 is connected bythe conductor wire. 59 to the conductor wire 14 and thence to the opposite contact of the switch 32.
