CINEMATOGRAPH AND GRAMOPHONE MACHINE.

Specification of Letters Patent.

Patented June 19, 1917.

Application filed June 22, 1915. Serial No. 35,637.

To all whom it may concern:

Be it known that I, Fnnmnixxn voN MADA- mm, a subject of the Austrian Emperor, and a resident of New York. in the State ofNew York, United States of America, have invented a certain new and useful Improvement in (linematograph and Gramophone Machines, of which the following is a specification.

This invention relates to improvements in cinematograph and grainophone machines, that is to say to apparatus, of the type described in my prior Patent No. 1,139.241 of May 11, 1915, for taking, viewing or projecting a succession of pictures upon a traveling film or paper strip, hereinafter referred to as a film, the machine being used to view or project the pictures on the film in a manner to represent a moving subject, or as a series of varied and stationary sub jects, the machine being also provided with mechanism for enabling it to be used as a gramophone the arrangement being such that either device may be used independently of the other or the two may be used together the two parts working in synchronism if a gramophone disk or record synchronized with the picture has been provided for the purpose.

The principal object of the invention is to combine a cinematograph and gramophone apparatus in such a manner that the combined mechanism is simple and capable of being easily and quickly disconnected so that either device may as stated be used alone if desired, certain parts of the mechanism being employed for driving both devices.

It will be understood that in using in this specification and claims the term cinematograph a viewing apparatus as well as a projecting apparatus is included, while in the term gramophone is included other forms of talking apparatus such as those of the cylinder type.

Further objects of the invention are the simplification and improvement of certainof the details of construction all of which will hereafter be more fully described.

The invention will now be described with reference to an embodiment thereof illustrated by wayof example in the accompanying drawings in which Figure 1 is a side elevation showing the machine in a position for viewing the pictures within the machine by means of an attachment comprising focusing tubes and eye pieces.

Fig. 2 is a plan of the machine with the cover or top thrown back.

Fig. 3 is a sectional elevation on line 33 of Fig. 2.

Fig. l is a sectional elevation on line 4-4; of Fig. 5 of the operative mechanism, removed from the casing, drawn to an enlarged scale.

Fig. is an underneath plan of the operative mechanism, removed from the casing, drawn to the same scale as F ig. 4.

Fig. (3 is a longitudinal section of the gate mechanism, drawn to an enlarged scale.

Figs. 7, 8 and 9, are front, side and back elevations respectively. drawn to an enlarged scale, of the means for adjusting the shaft upon which the shutter is mounted, and for driving said shaft directly, and

Fig. 10 is a plan of a part of the top of the casing illustrating the connection between the driving mechanism and the gramophone disk plate.

In. the drawings, 1 represents the outer box or casing,2 a condenser, 3 the lens holder, 4 the focusing tubes and eye pieces, which may be of the known prismatic or binocular form. for viewing the pictures within the machine, 5 the film box, (3 the table or framework supportl'ng. on its upper side, the condenser 2, film box 5 and gate mechanism 7, and. on its underside the driving mechanism which will be hereinafter more fully described, 8 the reproducer of the gramophone, 9 the movable arm or tube supporting said reproducer, 10 the fixed support for such arm leading to' the trumpet or resona tor 11 situated in and forming the bottom of the box.

The film box 5 which is preferably of the form described in Patent No. 1,100,591, dated June 16, 1914, is adapted to accommodate two spools on which the film 14 is wound, the spools are provided'with cranked spindles adapted to be engaged by cranks 15, 16,'forming part of the driving mechanism, the film box, when in position rests between the flanged parts 17, 18, formed on the table 6.

As described in the aforesaid specification the film box has a passage midway between the two spool boxes to enable light from the lamp or other source to pass through to the film, further description of this feature is however unnecessary.

The gate mechanism 7 through which the film 14 passes, is illustrated on an enlarged scale in Fig. 6, and comprises a fixed vertical plate 19 provided with rounded edges and tapers toward its up er end, a .recess of thesame width as the film 14 being pro vided in the lower part of said plate. Co operating with the plate 19 is a movable plate 20 supported on two studs 21, 22, (Fig. 2) slidably mounted in a plate 23 carried by atubular part 24, slidably arranged in an extension 25 formed on the lens holder 3. The part 24 is provided with a bolt 26 furnished with a finger 27 which passes through a slot 28 formed in the tubular part 24 at rightv angles to its axis, so that the bolt 26 has only a limited rotary movement within the part 24. In order to impart a slight longitudinal movement to the part 24 and thereby to the plate 23. an angular slot 29 is formed in the extension 25. For the purpose of providing resilient pressure between the parts 20 and 23, a leaf spring 30 is supported on the studs 21 and 22 between the parts named. To place the film'in position the finger 27 is moved into the position shown in Figs. 2 and 3, the film is placed between plates 19 and 20 and, to prevent the film from catching-againstthe projection '31 on the plate 20 which is adapted to enter the recess in the plate 19, the plate 20 is provided with a rounded projection 32 the plate 19 being correspondingly. recessed to receive said projection. -When the film is in position the finger 27 is turned over'to the right, the plate 20 is thereby moved toward the plate 19, in a direction at right angles to the film whereby the latter is held without I undue pressure in the recess provided therefor, the pressure being equal throughout the width ofthe gate. 23 and the leaf spring 30 are all furnished with rectangular apertures of the size of the picture throughwhich the light rays pass to the lens 33 or to the attachment The film is drawn through the gate by the pin sprocket wheel 34. the pins on which engage with recesses formed in the edgesv crank 16 is mounted.

The plates 19, 20 and of the film, a roller being provided at the other or left side of the gate for guiding the film from the left hand spool into the gate.

The driving mechanism located below and supported by the table 6 comprises a shaft 36 supported on lugs 37 and 38 depending from the table 6 on which shaft is fixed a worm wheel 39 gearing with a worm 40 on a shaft 41 arranged below. and at right angles to, the shaft 36. The shaft 36 is provided with a bevel wheel 42 engaging with a bevel wheel 43 mounted on the lower end of a vertically disposed spindle 44 which spindle also carries one part of a frictional coupling 45 the co-acting part being carried by a sleeve 117 surrounding the spindle 44, upon the upper end of which sleeve the This crank serves to wind the film on the right hand spool while the picture is being viewed or projected. the frictional coupling 45 prevents the film from being wound too tightly on itself and possible breakage for, when the film is fully wound the crank 16 remains at rest notwithstanding the continued movemeut of the driving mechanism.

A crown wheel 46, mounted on the shaft 36, is adapted to engage with a pinion 47 mounted on a vertically disposed spindle 4 upon the upper end of which the crank 15 is fixed. When the shaft 36 is moved longitudinally in the direction of the arrow (Fig. 4), in the manner hereinafter described, the crown wheel is brought into engagement with the pinion 47 and rotates the crank 15 in the reverse direction to that of the crank 16 thereby winding the film on the left which the crank 15 is rotated and also to prevent undue tightening of the film upon itself, the pinion 47 is not fixed on the spindle 48 but is loosely mounted thereon and frictionally held between two collars 49 and 50, the former being fixed to the spindle and the latter slidable thereon, by means of a. spring 51, placed between the collar 50 and an enlarged end 52 formed on the spindle. By this means when the film 14 is fully rewoundon the left hand spool and the mechanism is still in motion, the pinion 47 will slip freely on the spindle 48.

The shaft 36 is moved longitudinally by means of a reversing arm 53 pivoted on the pin 54 depending from the underside of the arrow, Fig. by means of the-knob 58. the spindle 59 of which passes through the table 6 and engages with the slotted end of the arm 53, the spindle 36 is caused to slide longitudinally and thus remove the bevel wheels 12, 43, out of mesh and bring the crown wheel 46 into mesh with the pinion l? for the purpose above described.

The shaft 41 is supported at one end on a lug 60 formed on the table (5, and at the other on a framework 61 secur d to the framework of a motor 62. A shutter 63 is fixed on the shaft 41 and said shaft also carries two clutch elements 64, 65, the element 61 is mounted freely on the shaft and is provided with a disk part 61*, while the element on is slidably arranged on but rotates with said shaft and is provided with an annular recess 65*.

The disk part 64. which is formed with a beveled periphery. is furnished with a cam tooth 60 arranged to engage with a tooth or star wheel 67 on the spindle 68 upon the outer end of which is mounted. the sprocket wheel 34 for drawing the film through the gate 7. The spindle is supported at its upper end on an adjustable pivot pin 69 fixed in a lug 70 formed on the plate 19 of the gate 7 and at its lower end on a fixed pivot pin 71 fixed in a part 72 depending from the underside of the table 6. v

The cam tooth 66 turns the sprocket wheel 31 through an angle sufiicient to change the picture at each complete revolution of the shaft 41.

hen it is desired to rewind the film on the left hand spool it is first necessary to open the gate 7 and to release and hold the film away from the sprocket wheel 34, this latter being efiected by means of the reversing arm the extreme inner end of which is slotted and engages with a downwardly projecting pin 73 carried by a crank arm 74 loosely mounted on a sleeve 74* attached to table 6 and is held thereon by the collar 68*. A vertically disposed pin 75. carrying a roller 7 5*, is mounted on the other end of the crank arm 74. said pin projecting through a slot 76 formed in the table 6. When the arm 53 is moved in the direction of the arrow (Fig. 5) the pin moves toward the gate 7 and releases the film from the pins on the sprocket wheel 34. With the parts in this position'the film may be rewound on the left hand spool.

In order to provide means for taking up wear on the disk part 64. the shaft 41 is mounted on pivot pins 77 78. adjustably mounted in the lug 60 and framework 61 of motor 62 the mounting of the pivot pin 77 being shown morev clearly on an enlarged scale in Figs. 7, 8 and 9. As shown. the pin 77 is provided with an eccentrically dis osed pivot point, the pin being maintained 1n the desired position by a set screw 78 and also by a set screw 79 carryinga washer 80 engaging with a recess in the pin 77. The

disk part and cam tooth being furnished with a beveled periphery are able to enter farther into the toothed wheel 07 as the distance between their respective shafts is decreased.

For the purpose of providing means for enabling single pictures to be viewed. the shaft 11 is furnished with a gear wheel 81 adapted to mesh with a wheel 82 carried by a spindle 83 mounted in a sleeve 84: provided on the lug (30. the outer end of such spindle being formed with a square or screw threaded as shown to receive a crank handle. The casing 1 may be provided if desired with a mark to indicate one turn of the handle, for th purpose of indicating when a picture ha been broughtinto register with the viewing aperture.

The gramophone mechanism is operated by and connected to the ciuematograph mechanism above described in the following manner:

A worm wheel 8 is mounted on the shaft 30 and meshes with a worm wheel 85 mounted on a spindle 81', supported by a bracket 87 secured to the table 6. The upper end of the spindle 86 passes through the -maintained in its highest position on the spindle 80 by means of a spring 90 located within the sleeve and bearing on said sleeve at one end and on a pin 91 passed through the spindle 86 at the other, the sleeve being furnished with a bayonet slot 92 in which said pin slides for the purpose hereafter referred to.

The worm wheel 89 meshes with a worm wheel 93 mounted pn a horizontally arranged spindle 94. supported in a double bearing 95. secured to the outside of the cover 12. as shown on an enlarged scale in Fig. 10. The spindle 94: carries at its other end a worm wheel 96 which is adapted to engage with a worm wheel 97 mounted on a vertically disposed spindle 98 upon which the supporting plate 99 for the record disk 100 is mounted. The worm wheels 89 and 93 being arranged at rightangles to each other permits the gears to disengage easily when the cover is raised The spindle 98 is provided with any desired form of governing means, that shown being of known form and comprises a worm wheel 101 mounted on the inner end of the spindle 98 and meshes with aworm 101 formed on a horizontally disposed'spindle 102 upon which the sliding sleeve 103, to which one end of each of the springs 104 carrying the weights 105 are secured. the other end of each spring being fixed to the spindle 102.

When it is desired to operate the gramophone in combination with the cinematograph the parts of the mechanism occupy the position shown in Figs. 2, 3, 4 and 5, but should it be desired to operatethe cinematograph part alone the sliding sleeve 88 is pushed down on-the spindle86' and-given.

' driving mechanism, caused by the engagement' of the cam element with the toothed wheel, to throw such mechanism out of gear, and, to effect this the clutch element 65 is slidably moved on the shaft 41 so as to disengage said element from its co-acting part 64, and the means for effecting this comprises the bent arm 106 pivoted at 107 on the part 7 Q, the inner end of such arm engaging with the annular recess 65* formed in the clutch element 6!", the outer end passing through an aperture 108 in the table 6 and terminating in a knob 109. V

In order to prevent any rotation of the clutch element 64 while the clutch element (35 is disengaged therefrom, said element is provided with a pin 110 which is adapted to engage with an arm 111 fixed on and mov-.

ing with the arm 106.

The mechanism may be driven by means of a handle 112 mounted on the end ofthe shaft 36, which may be square or screw threaded as shown, or it may be driven by the -motor 62 connected up to a suitable source of current supply which may be cut in or out by a switch 113 (Fig. When it is desired to View the picture by means of the attachment 4 the entire box is preferably tilted up by means of the frame 114 held at the desired angle by means of the arm 115.
