This invention relates to moving picture machines and phonographs.

One object of the invention is to provide in a unitary cabinet a moving picture apparatus and a phonograph.

a A .further object of the invention is to provide means for synchronizing the moving pictures and the phono'graphic productions so that the sounds may be accurately fitted to the pictures as where persons in the Fig. 2 is a front elevation of the a'pparatus, the lower door of the cabinet being removed;

Fig. 12 is asection through the top of the cabinet on the line 2727 in Fig. 11.

Referring to the drawings, the apparatus comprises a casing or cabinet A within which the machinery is mounted. At the top of operating apparatus for controlling the movgrooved co the'front of the cabinet is a moving picture slida-ble upon rods G and H so that it may be pushed backward into normal operating position or drawn forwardly to the front of the casing so that it is readily accessible from the outside for the purpose of threading in the film or for other purposes.

The lamp of, the projector is inclosed in a housing I which'commun'icateswith the intake of a blower K driven by the motor F.

The air thus withdrawn from the lamp house is expelled downwardly through a flaredputlet L. This air circu ation keeps the lamp cool. i

The phonograph may be of any'of the well known types, for instance one employing a table adapted to receive a disk record; this table being at the upper end of the shaft 1 which is rotated by the electric motor F in the manner now to be described. v

The shaft 2 of the motor F is journaled in the gear casing 3 and base thrust collar 4 fixed thereon so as to prevent movement of the shaft through the hearing in one direction. On the other side of the bearing a spiral gear 5 is fixed upon the shaft and acts as a thrust collar which prevents endwise movement in the other direction. In line with the shaft 2 is a shaft 6 journaled in the casing. Outside this journal a cone pulley 7 is fixed'upon the shaft 6. This "cone pulley prevents endwise movement of clutch between these shafts is provided and consistsof pins 9 fixed to the shaft 2 and'a lar 10 splined upon the shaft 6 so as to be slidable thereon but not turnable with relation thereto. The collar 10 has a projection 11 which is extended into the path of the pins 9 when the clutch is in engaging position, so that the two shafts are locked and turn together. The collar 10 may be moved along the shaft 6 by means of a. leveri'i2 "pivhted' at 13 girl the 'geanca'sing and having a forked end which straddles the collar the extremities of the fork engaging'in the groove ofthe-c'oH-ar 10. Preferably a roller as 14 'is' rotatablymounted: on the end of eacharmof the fork for engagement with the sides of the groove so as to reduce the friction.

The spiral gear 5 meshes with the spiral gear- 15 which is fixed-on theshaft-16 journaled in the-bearing 17. The hub of the gear '15 on one side of the bearing-and: the thrust --collar-18'fixed. to the shaft 16 on the other-side of thebearing, :prevent endwise movement of-the-shaft. Erom'the-end of the shaft 16- is projected pins 19-adapted to be engaged by pins. 20 projecting from a grooved collar 21 splined upon the shaft 22. This collar may be slid along the shaft to engage and disengage the, pins -19 -and-2O by means of a forked lever-arm projecting into the collar groove. By this means the shafts 16 and 22 may be connected in driving relation on disengaged therefrom.

The shaft 22 is journaled in the casing 3, having fixed upon it, on the inside of the bearing, a thrust collar 23 which -prevents the-shaft slidingoutwardly through the bearing. Outside the casing a cone pulley 24 is fixed upon the shaft and serves as a thrust bearing to prevent the shaft 22 from sliding inwardly. .The pulley. 24 is connected by means of a belt25with a cone pulley. 26

which is fixed on a Shh-a 27. This shaft turns in bearings 28 and 29 mounted on the f casing 30. The pulley 26=acts asathrust collar to prevent inward movement of the shaft 27. A worm 31 is fixed on the shaft 39 which is rotatably mounted upon the shaft land also fixed tothe sleeve 39 is .a wormwheel 40. The worm wheel 40 en- .gages with a worm 41 fixed to a shaft 42 which is journaled in the casing 30 at 43 and is provided with a thrust collar to prevent its endwise movement. :This shaft 42 extends-for some. distance-beyond the casing -30 where it is provided with a finger piece .Theshaft 42 is .normally stationary and or handle 44 by which it may -be turned.

holds the worm wheel 40and the gear 38 stationary; Rotation of the worm 31. rotates the-spider 34 and the gears 36, rolling upon the stationary gear 38, turn the gear taken advanta the gear 38 were entirely free to move, the

spider 34 would be ineffective to produce rotation of the gear-37 and any movement of the gear 38- alters the speed relations of the shaft 1 and the driving ineans. This is of to produce a change in the phase relations of the driving means and the phonograph. This is brought about by turning the shaft 42 in onedirectionor the other. Movement ofthe. gear 38 in one direction or the other is thus accomplished and the speed of the shaft 1 is increased or decreased with relation to the drivi;.g means during. the period of movement offthe gear 38. The phase of the phonograph is thus advanced or retarded with relation .tov the driving means and the gear 38, having again assumed its normal stationary -condition, .the

relative speeds of the phonograph. and driving means will. be asbeforebut their relative phase will have been shifted. This-aids in synchronizing different parts of the apparatus which will be hereinafter referred to.

In threading ina new film or in any other operations in which access to the. moving picture apparatus is to be had, it is-more or less inconvenient if this .apparatus occupies its normal position within. the-cabinet. For this reason the moving picture apparatus is formed into an unitary structure which may be moved from its normal position in the cabinet to a position where it is more readily accessible. To thisend the rods G and H are supported by stationary posts or standards projecting upwardly .from the base and the apparatus, referred to aboveas movable, is formed in a unitary structure to slide 'upon thesebars. This unitary structure comprises a gear casing ahaving mechanismiadapted to drive the film and reels, the payingeout reel Zpfor the film, the take-up reel 0 for the film, the shutter d, the intermittent and steady feeds for. the film and the object lenses, the condenser lenses e being mounted upon the house or casinggof the lamp f. The structures thus referred to in a general way. will now be referred to in detail. I

The moving picture apparatus is driven fromthe pulley 7 which is connected with the cone pulley 45 b a be1t=46. The piilley 45 is fixed upon a s iaft 47 journaled in the.

thrust collar to. prevent movement of the shaft 47 in one direction while a thrust collar 48 prevents endwise movement of the shaft in the opposite direction. The shaft 47 is connected by a flexible connection 49, such as a coiled steel spring, with a shaft 50. This shaft 50 is joined by a telescopic connection with a shaft 51 which is hollow so as to receive the end of the shaft 50 and has a slot 52 into which projects a pin 53 on the '19, withthe shaft 55- journale d in the ar 'casin 56'at the bearings57, 58 ,and 59-.

flexib e and telescopic connections 'ust describedfumishes the driving means tween the stationary driving apparatus and the shiftablemotion picture a paratus.

' apparatus and the phonograph'shal run in driven by means of beveled 'upon the shaft" 47 and 199 sp ined upon the the right relation, the moving picture drive shaft 47 is detachably connected with the shaft 27 from which the phonograph is ears 198 fixed shaft 27 'so that it m'ayslide out of and into mesh with the gear 198. Connected with the gear 199 is a grooved collar 200similar to the grooved collar 10 and which may be operated by a lever to slide the gear back and forth upon the shaft 27. When the gears 198 and 199 .are out of mesh the phonograph and moving picture a paratus may beoperated independently w ile,;as before stated, the two apparatus are held in proper relation when the gears 198 and 199 are in engagement.

graph may be regulated in speed by shifting the belt 25 longitudinally of the pulleys 24 and 26 while the speed of themoving picture apparatus may be regulated by shifting the belt 46 upon the p11 eys 7 and 45. The belt 25 may be shifted by means of a belt shifter 201 which embraces the belt 25 and is fixed to the sleeve 202 which carries at its upper end a handle 204 by which it may be turned to shift the belt.

' Within the sleeve 202 is a shaft 205 having fixed to it at its upper end a handle'206 by which it may be turned. At its lower end it is journaled in a bracket 207. Fixed to the shaft 205 is an arm 208 pivoted to a link 209 which turn is pivoted to one end of a bell crank 210 pivoted atits angle in the bracket 211. The other end of the bell crank terminates in the belt shifter 212 which embraces the belt 46. It will thus be apparent that the handles 204 and 206 can be used to shift the phonograph driving belt and moving picture driving belt respectively by moving them in one direction or the other. If when the phonograph and moving picture driving means are connected together by throwing the gears 198 and 199 into mesh, the belts 25 and l6 are not the drivin In order to insure that t e movin picture d been. completed, whether the operator attentive or not, automatic means is provided for stopping the mechanism when the last ofthe film has 'passed-or when the record has been completed. The-stoppage of the mechanism may, however, be effected at any I desired time;

As hasbeen before explained the moving picture apparatus maybe disconnected from mechanism by disengaging the ins 9-an 11. Also the phonograph may disconnected from the driving mechanism by 'idisengaging the pins 19 and 20.- To operate the moving picture control clutch lever-12 a magnet 213 is mounted'upon the casing 3;" The armature 214 of this ma s a is pivoted at 215 upon the post 216 fixed" to the casmg 3 and forms a part of the magnetic circuit of the magnet 213. Pivoted between the lever 12' and the 60st 216 are two toggle links 217 and'218. 1 pon the tail of the armature 214 is an adjustable stop screw 219' adapted'to engage with the knee of the toggle'and so adjusted that-when the screw is in its lower position the toggle will be slightly over set so as to hold the lever 12 in position to drive the moving picture apparatus. When the magnet 213 is energized and its armature attracted the screw' When running independently the phone 219 will break the toggle. The'arm 12 will then be thrown by a spring, presently to tus will be disconnected.

To provide for the resetting of the clutch to connect the moving picture apparatus a link 220 is pivoted to the lever 12 and also to the arm 221 which is fixed upon the sleeve 222.. This 'sleeve'is'extended vertically and at its upper end is provided witha handle 223 which tends to move under the influence of a spring224 in suchdirection' as to throw the clutch 'control=lever 12 into disconnecting position. A spring 225 normally holds the armature "214 retracted from the magnet.

To operate the clutch connecting the phonograph a lev'er arm 226 is provided connected by toggle links 227 and 228 with the post 229 fixed to the casing 3. This post forms a part of the magnetic circuit of the electromagnet 230 and has pivoted to it at 231 the'armature 232 of that electro-magnet.

The tail of the armature 232 carries an adjustable stop screw 233 which, when the armature is retracted b the spring 234, permits the toggle to-be slightly over set so as to hold the clutch lever in connecting position. When the magnet 230 is energized and its armature retracted, the screw on the tail of the-armature kicks open the toggle and permits the lever to move into discon necting position under the influence of a spring 235 connected with'the handle 236 which is fixed upon the shaft 237, extending through the sleeve 222 and being urnaled at its lower end in the casing 3. This shaft is connected with the-lever 226tby' means'of' levers into connectingupositionwhere..they

outthe phonograph and moving picture .door 240.

an-arm 238 fixed upon it andalink 239 pivoted tofithat. armv and to the lever 2 26. \Vhile the springs 234 and 235ltend' to throw clutches; movement of the'handles' 223 and 236 against the springs will throw theclutch will be held by -their .;toggles. --.Accessl to thesehandles may be had through aniopening in-thejfront of the cabinet closed bya In-the drawing (see particularly Fig. 9) 241 and 242 are the electric supply means which may be connected and disconnected by means of the double poleswitch 243.

The circuit of the magnet 213 or of the magnet 230.may be-closed at will by means of the two way-switch 244, this affording a means for throwing either or both --the phonograph. and moving picture apparatus out of operation-at will, While either'or both of these apparatus may be throwninto-operation at will by means of the handles 223 and 236 asbefore described. One terminal of the lineis connected-with the frame of the machine upon which the moving picture film runs while one terminal of the-electromagnet 213 is connected with the spring 245 which .is insulated from :the frame. The

otherterminal of the magnet-1s connected with the other side of the line. The contact 245 is normally held-outof-engagement with the' frame because of the film beingi-nterposed; -When the film has been used up I and therefore-withdrawn from between the spring contact and theframe, the circuit of the magnet 213 is completed and the moving picture clutch is thrown out of operation. The clutch lever 12 serves as the arm of a switch for making the circuit of the projector lamp. One terminal of this lamp is connected with the'supply main .241 while the-rother terminal is connected with. the switch clips 246 which are insulated from the frame' When in engagement with the lever 12 they are electrically connected with the frame and thence to the line 242,-so that the circuit of the lamp is completed when the motion picture clutch is in connecting position and is automatically extinguished-when the clutch is disconnected. To throw the phonograph out ofoperationwhen-a record has been completed, the phonograph sound arm 247 carries an insulated spring cont-act 248. Mounted upon the cabinet is: uninsulated contact 249 adaptedv to be engaged by the contact 248 when the sound arm has moved inward sufliciently. At the central part of-the record disk is provided a groove 250 which is connected with the sound .grooveby a- -steeply inclined spiral groove 251,; While the needle is moving across the record-. lthe contacts 248 and 249 will be openvbut assoon-as the and of the-sound groove-is reachedthei needle .is iq fl y a ried intothe.groove250wVhen the contacts .248 and 249.. will;come intoengagement. -.This will complete; the circuit of themagnet 230, one tcrminalof that magnet being connected with the line 241, the other-terminal beingconnected with the contact 249 andthe contact on the, sound, arm being connected ,with the line 242.-

The motor F, which is referably of -the shunt-or compound type as one terminal connected:with the line 241 while the other terminal is connected with thefinsulated switch clips 252 which are adapted to engage with the switch blade 253 pivoted to he frame at 254. "Being pivoted to .the frame the blade is connected with the line 242. A

spring 255 tends to hold the switch open. It

is closed byan endwise movable; push bar 256 pivoted atone end to the switch blade and. at its other lend carrying a roller 257 adaptedto be engaged by the arm 258 fixed upon the sleeve 222, when the moving picture clutch is -:in connecting position. When the phonograph clutch is also in connecting;

position the arm 238 will lie alongside the frame 238 and both will bear upon the roller .257 and thrust the switch blade. 253 into closed position. When both the clutches are in disconnected position, both the arms238 and 258 will be moved away from the roller so that the spring 255 may force the switch blade 253 into open position. So long ,however,.as either of the clutches is in connecting position one of'the arms will. be against i be printed upon the film and successivelyexhibited upon the screen by moving the film through the projector step by step to exhibit the successive pictures, each picture remaining in position as lon as desired. Tothis end the shaft 47 may be extended as at259 and provided with a, square end adapted to fit in thesquare socket of a handle 260m opening in the casing. being provided for this purpose. It w'illnow be apparentthat upon disconnecting the moving] picture clutch and the gears'1198and 199 thefilm advancing means mavfbe operated as desired by turning the handle 260. At the same time the phonograph may be operated by the motor if desired.

It will now be apparent that, ifthe main switch 253 be closed, and either the clutch for operating the moving. picture apparatus or that for operatingthe phonograph, or.

both, be thrown into engagement by thehandles 223 and 236 respectively, the motor will start into operation. One of the clutches must, however, be in engagement to secure closing of the motor circuit. If neither is in engagement, the motor will be open circuited, thus avoiding waste of power when ,-neither the moving picture apparatus or the phonograph is in operation. Either or both of the picture apparatus and the phonograph respectively by means of the switch 244 acting t rough the electromagn'ets 213 and 230. Also the clutch for the phonograph is thrown out upon the closing of the contacts 248 and 249 by the sound arm after a record has been completed, while the clutch for the picture apparatus is disconnected when the contacts 245 and 116' engage after a film has completed its run.

When the phonograph and picture apparatus are operated together and the sounds from the phonograph should correspond with showings of the pictures, as, for instance, where an actor in the pictures is supposed to be speaking or singing the words emitted from the phonograph, the picture apparatus may be connected in rigid speed relationship by means of the gear 199 being thrown into engagement with the gear 198 on the picture, drive shaft, connection with the phonograph drive being made through the shaft 27 and gearing as before described,

the gears 198 and 199 being disengaged when it is desired to operate either the picture apparatus or the phonograph alone, or when it is desired'to operate them together, but independently. The two apparatus may. be

held in the proper speed relationship, as described, but if under such circumstances incidents of the phonograph and pictures which should be co-incident are separated by a time interval, in otherwords if the incidents are out of phase, the result is con- Such a situation exists where an should be coincident with certain words .which are produced later or'earlier by the phonograph. By means of gearing, as before described, 0' rated by the rod 42, the pictures and p onograph may be brought into proper phase relationship.

Whilethe invention has been described in what is considered its best application, it a the connected apparatus may have other embodiments without de-' parting from its spirit and is not limited to the structure shown in the drawings.
