LOUIS MANDEL, OF

on 10sec, rnnruors a CONVERTIBLE MOTION-PICTURE MACHINE.

To all whom, it may concern Be it known that I, LoUIs MANDEL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Convertible Motion- Picture Machines, of which the following This invention relates to improvements in motion picture machines adapted to be used for photographing pictures upon a strip in rapid succession, and subsequently employed for projecting the pictures upon a screen, the machine being also adapted to be used for photographing what is known as"still pictures and subsequently projecting the still pictures upon a screen.

A further object is to provide an improved machine of this character also adaptedto be used for printing the positive film from the strip containing. the pictu'resto be printed.

A further object is to provide an improved compact device of this character,

which will be of small dimensions, and so constructed that the operating mechanism may be readily removed from the casing as a single unit, and as readily inserted into the casing, the frame of the operating mechanism also serving to, divide the casing into three compartments, two of which compartments being adapted to receive and hold the film rolls. g

To the attainment of these ends, and the accomplishment of other new and. useful objects, as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating the invention and in which:

Application filed April 16, 1915. Serial No. 21,688.

Referring more particularly to the drawng, the numeral 10 designates generally an inclosing casing, having an open side which is closed by a closure 11. The casing is provided with anoopening 12 in its wall 13 and connected with the opening is a lens 14, preferably located inside of the casing. The vwall 13 of tliecasing is provided with'open grooves 15, while the side walls are with grooves 16, 17.

provided I The operating mechanism is arranged W1th1n the casing and comprises a support,

The structure thus formed, is adapted to be. lnserted into the casing, so that the edges of the walls 19, will enter the grooves 15, 16 and 17, and the structure is of such a size as to extend across the casing, so that the walls 19 will divide the casing into two end compartments, 22, 23 and an intermediate compartment 24.

Mounted upon the structure thus formed and supported in any suitable manner, is a rotatable toothed element or sprocket wheel 25, a portion of which projects through a suitable opening 26* in the wall 18 of the structure. Connected with the shaft of this sprocket wheel is a Geneva element 26, and a cooperating Geneva element 27, which latter is provided with the operating pin 28, and is connected with a shaft 29 which has secured to it a gear 30. The gear 30 meshes with a gear 31, which latter is connected with a shaft 32, and mounted upon the shaft 32 is a pulley 33, fora purpose to be hereinafter set forth. The gear 31 in turn meshes with a gear 34. This gear 34 meshes with a gear 35 which has connected with it to operate therewith, a gear 36, and the gear 36 in turn meshes with another gear 37, and these series of gears constitute a train of gears by means of which the Geneva elementis rotated and this element in turn rotates the Geneva element 26 and consequently, the sprocket 25, to feed the flexible strip 38 across the field of the lens 14.

Supported by the walls 19 of the supporting structure are brackets 39, 40, upon which are mounted the reels 41, 42, which hold the flexible strip 38, and the bracket 40 and reel 42 are located in the compartment 22, while the bracket 39 and reel 41 are located in the 4 compartment 23.

The gear 37 has connected with it a socket 43' (see particularly Fig. 3), while the gear 34 has connected with it, a socket 44, and a similar socket 45 is connected with the gear 30. These socketslare adapted to successively receive a crank (not shown) and which is inserted into the respective sockets from the outside of the'casing, thereby ren- .deringv it possible to impart a variable speed of rotation to the sprocket to vary the speed of the movement of the flexible strip 38 at the will of the operator, and at'difl'erent points in the train of gears. I l V Connected with the shaft 46, upon which the reel 41 is rotatably mounted, 1s a pulley '47 which is mounted in alin'ement'with the pulley 33, and, a flexible belt 48 passes over these pulleys vand through suitable apertures in the wall 19 of the support, so that when the sprocket 25 is rotated to feed the film from the reel 42, the film will be wound upon the reel 41. a

- shaft 29, for the purpose of insuring a A balance wheel49 is connected with the steady movement.

The wall 18 of the supporting structiire is provided with an aperture 50 which is mounted in alinement with an aperture 51 in -the,closure 11, and this aperture '51' is preferably of a size somewhat larger than the aperture 50 and is provided with a conical shield 52 for directing the'light into the aperture 50.. Supported by the wall 18 is a gate or guide 53 which is pivotally connected thereto as at 54 and is provided with an aperture 55 arranged in alinement with the a ertures 50, 51, and a catch 56'is also provi ed for holding the gate closed. The flexibld'strip 38 passes between the gate 53 and the'wall 18 so as to pass across the registering openings 50, 51, 55 and in order to hold the strip in position, and against the sprocket wheel 25, rollers 57 are provided for thatpurpose. The gate is provided with cut awa portions 58, 59, in 1ts up er and lower'e ges and through which portions tQ flexible strip is adapted to pass, under certain conditions; A shutter 60 is also provided and mounted upon the supporting structure. The shaft 61 of the shutter is mounted in suitable bearings and has con-' nected with it a bevel gear 62, which latter meshes with a bevel gear 63, the gear 63 being connected-to operate with the gear 35, so'that when the mechanism is actuated to feed the flexible strip, the shutter 60'will be correspondingly rotated.

Finders 65, 66 are provided, and the opening 51 in the closure 11 is closed by means of a temporary closure 64, and this temporary closure is employed when it is desired to use theapparatus for photographing puroses, the feeding mechanism being operated y means of a crank from any point desired in the train of gears. Under ordinaryconditions of sufficient light, and when motion .to the views, the feedin Fig. 6, an

mechanism may be operated from the gear 37, but when there is not suflicient light and it. is desired to give a little longer exposure,

mechanism is operated from the gear 34 in the train. When it is desired, to photograph what is known as still, pictures, that is, by advancin the flexible sensitized stri the distance 0 one picture "or view, the eeding mechanism is operated from the shaft 29 by placing the crank in the socket 45, and, one complete revolution of the gear 30 will be suificient to advance the sensitized strip the. proper distance.

When it is desired to use the apparatus for subsequently projecting the picture on to a screen, the temporary closure 64 is re-' moved and. in its place is arranged an attachment 67 which is provided with a condenser lens 68 and which lens is mounted in alinementwith the registeringo enings 51,

55, 50 and in order to provide su cient light for the purpose of projecting pictures, a source of light 69 is provided, which is preferably arranged within a casing 70, the latter being adjustably connected with the attachment 67, to be moved toward or away from the condenser lens 68.

The printing is accomplished by feeding the sensitized strip 38 through the apparams in the manner as already described, and the'objects to be printed upon the strip 38 are arranged upon another flexible strip 71,

which is fed from a reel 72 arranged on the outside of the casin by means of a detac ablesup ort 73. The flexible strip 71 is then passed into the easing through an opening 74 which latter is closed by a flexible closure 7 5, that contacts with the flexible strip as it passes throu h the opening, to prevent the entrance of lig t at that point. in close proximity to the cut away portion 58 of the ate 53, as shown more clearly in (f the flexible strip then passes over the adjacent roller 57 in contact with the sensitized strip 38, throu h the gate, over the sprocket 25 through t e cut away portion 59 in the gate and then through another opening 76'again to the outside of the casing and whichopening 76 is closed by a flexible closure 77, that contacts with the flexible strip to prevent the entrance of li ht into the casing. With the two strips t us arranged, I: it will be seen .that when the feeding mechanism is operated, both of the flexible strips will besimultaneousl sensitized strip is maintained within the easing and the other strip will be passed from the outside of the casing into the casing to be printed from and then a ain to the outside.

If desired and in or er to support the flexible strips in contact with each other adand held in position hisopening 74 is arranged 'fed across the fieldof the condenser, whi e the jacent the opening 50, a removable support 78, (see Fig. 6), may be employed at that point. A supplemental gate 53 is connected with the main gate 53, by means of bolts 53 and springs 53 are also provided for yieldingly holding the supplemental gate, against the flexible strip so that the supplemental gate will yield to compensate any irregularity in the flexible strip. 1

Should it be desired, the condenser attachment'67 and the source of light 69 may be omitted and printing may be acc omplished either directly from the sun or the opening '51 may be arranged and held in alinement with anysuitable source of light. Printing may also be done for still pictures, by operating the mechanism from the gear 30 and when it is desired to project the still pictures, the feeding mechanism may be operated from the same point.

With this improved construction, it will be manifest that the apparatus is convertible for a number of difierent'uses, thereby combining in a single construction a multiplieity of devices. It will also be manifest that all of the operating mechanism is mounted upon a supporting structure, which is removably held within the casing, and when it is desired, this structure, the operating mechanism, the shutter, and reels for the flexible strips may be bodily removed from the casing as a single unit.

Obviously many changes may be made in the details of construction and in the combination and arrangement of the several parts Without departing from the spirit of this invention.
