l Specification of Letters Patent. Patented Feb. 19, `1918.
` Application led April '11, 1914. Serial No. 831,147.
To all whom 'it mag/concern.' I
Be it known that I, HERMAN C. SGHLICKER a citizen of Germany, and a resident o the borough of Manhattan, in the county of New Yorkand State of New York, have invented certain new and yuseful Improvements in Kinetographs, of which the following is a specificatlon. A p
This invention pertalns to an apparatus for taklng motlon lctures, and more par ticularly relates to t e production of a num ber of images of reduced size upon an endless film. I
One of the objects of the invention is to produce an improved apparatus of the char-l acter described that is especially adapted for use by amateurs.
A further object is to adapt the kineto graphic apparatus for the ready insertion and removal of a lurality of film holders, so that unexposed lms may be placed therein in daylight, and others substituted after exposure, without danger of the films becoming light-struck. l
Another'object is to provide a kinetograph with a self-contained spring-motor, and appropriate connections, adapted to propel the endless film band, as well as a co-acting shutter and lens traverse, in such a manner that a person can hold the appa. ratus in hand while in action without causr ing detrimental vibrations therein.
A still further object is the provision of means for so positioning the images taken on the film that the same will appear correctly placed at all times and in proper sequence thereon, without wasting any of the films sensitized surface.
Still another vobject is the production of a motion picture camera composed of but few parts, simple to operate, and of low cost of manufacture.
Further objects will become apparent as the specification proceeds.
The advantages of the invention are best closing a main drlve designed to impartcontinuous motion to a shutter-operating `mechanism' and intermittent motion toa film-actuating device; a third compartment Y communicating with the first and second, and containing an objective-translating mechanism connected up with the said intermittently-actuated device' to move in synchronism with a section of the film intended to receive the images, the latter being taken step by step in individually offset relation on the film and in helical formation; and a fourth compartment underlying the first, and wherein is located a spring-motor arranged for engagement with the main drive and to actuate the therewith connected mechanisms without affecting their respective steadiness of operation during exposure of the film to the light.
It will be manifest to those skilled in the art that the invention may be embodied in several different` constructions, the accompanying drawings showing one of these by way of illustration. A
In the said drawings:-

Fig. 6 is a fragmentary face view of a flexible film used in conjunction with the apparatus, the view illustrating diagrammatically the arrangement of the lmages thereon, considered both individually and collectively.
In these views, the letter A represents a casing which in the present embodiment of the invention is conveniently made of rcc tangular form, as shown in the drawings. This form of casing includes, therefore, a top wall 10, a bottom wall 11, a front wall 12, having an elongate opening 13, a rear wall 14, provided with a door 15, and sidewalls 16, 17. The several elements here enumerated as constituting the casing have other parts thereto attached or co-acting therewith, which will be the easier traced or located by reference to the numerals just given.
Inside the casing A, as shown herein is a vertical partition 18 and a raised floor 19 meeting each other at one edge. as best seen in Figs. 2 and 4, the same extending forward from the rear jamb and the sill of the door 15, respectively, for a predetermined distance within the casing, Where they join andrest upon a transverse partition 20, at their inner ends. See also Fig. 1. Running in the same direction as 20, are two other narrow partitions 21, 22, extending across the top and bottom Walls10, 11 respectively; each for a distance co-extensive with the width of the said floor 19, the upper and lower edgesgof the partition 22 being offset one from the other, as shown. These data are given merely as an example of a practicable construction, as will be understood, since obviously recourse could be had to numerous other means and ways of producing the requisite divisions in the casing.
A film-holder 25 is insertible through the opening covered by the door 15, into the above described casing A. In its preferred form, this holder includes parallel sides 26, 27, designed to face respectively the top wall l0 and ioor 19 of the casing; curved ends 28, 29, to be located respectively opposite the i'ront opening 13 in the wall 12 and` the door 15 of the wall 14; and a bottom 30, to`
be placed parallel with the side wall 17. These parts 27-30, form together an oblong container, which is closed by a cover 31, recessed as at 32 to take over the rim of the holder 25, and adapted to render the latter light-tight. The cover 31 may be held in position by spring catches, such for instance as are shown at 33, in the upper right-hand portion of- Fig. 2.
Brackets 34, 35 extend from the inner face of the said cover 31, into the film-holder 25. The bracket 34 revolubly holds a hexagonal or other prismatic roller 36, which normally is maintained in a relatively fixed position, and the bracket 35 aii'ords a similar support for a cylindrical roller 37, rotatably carried ina trame 38, resiliently sustained in the latter-named bracket. A spring 39 urges the frame 38 away from the bracket 35, while the outward movement of said frame is limited by heads or enlarged ends 40 of guide stems 41, these elements constituting a tensioning device for the lm, presently to be described. To hold the frame 38 in a retracted position, Whenever required, a slide 42, having elongated apertures 43, enlarged at one end as shown in Fig. 3, is adapted to take over reduced portions 44 of the .guide stems 41, when the frame 38 ispressed inward. This last operation becomes necessary when the film is applied to or taken o' the rolls 36 and 37.
The film upon which the images are taken consists of a tubular or endless flexible web 50, stretched over the aforesaid prismatic and cylindric rollers 36, 37, and having marginal perforations 51, arranged to take over teeth 52, at the opposite ends of the roller At such times as the roller 36 is rotated, the teeth 52 thereon engage the perforations 51 in the opposite edges of the web 50, and thus the latter is positively propelled, while the straight at faces of the roller present Correspondingly-shaped sections of the web outward. A gear-wheel 54, placed outside of the cover 31, is fixed to a projecting end ot a spindle 55, to which the roller 36 is fastened.
t The curved, forward end 28 of the filmholder is formed with a transversely-elongated opening 56, which is normally, covered by a suitable closure which may be a slidin ,door 57 as shown, prior to the insertion o` the holder into the casing. At a predetermined point inside the latter, for instance, under the floor 19, is attached a spring arm or a plurality of spring arms 58, having each a hook 59 at its free end, projected' into the path of a ledge 60 on the said sliding door. As the holder 25 is being inserted into the casing, the hook 59 encounters the ledge 60 in its highest position, to wit, when the opening 56 is closed. A further movement of the film-holder inward 100 causes the spring arms to yield, while at the same time the sliding door is pulled open and retained in that position by the hooks 59. To prevent light from prematurely entering the apertured end of the holder, dur- 105 ing its introduction into the casing, the surface of the tioor 19 upon which the holder 'slides may be suitably lined, for example with velvet, and a yielding strip 61, of felt or the like, may be applied transversely on the opposite side of the holder, to effect a lighttight joint thereover. A spring 62, bearing centrally upon the same side of the holder, from the under side of the top wall 10, may be employed to keep the holder firmly in position against the surface of the floor 19. The laterally-arranged springs y58 and centrally-disposed Spring 62 together serve as a positioning device for the holder, while the hooks of the former enable them to perform the additional function of an automatic door-opener and door stop. This constitutes a convenient construction, still it will be un- -derstood that some other type of closure,
equally effective, may be substituted for the sliding door 57, and that, whatever means are adopted for closing the apertured end 'of the film holder, the same could be operated in other ways.
The hereinbefore mentioned Vgear-wheel 54 130 fied herein maybe a star-wheel 71 of Geneva movement type. The latter, ina well-known manner, is give`n alternate periods of movement and rest by the other member of said pa1red gears, which may consist of a co-acting single-tooth or pin wheel 72. The intervals of repose of this intermittent mechanism correspond in extent to the superficial sections of the polygonal roller 36, the arrangement being such that, each time its motion is arrested,the said roller present-s one of its fiat or straight faces to the lightrays passing through an objective placed in front thereof. Any other suitable form of mechanism capable of imparting intermittent motion to the prismatic roller would, of course, subserve the same purpose. t
The impeller gear 72 is fixedly mounted on a spindle 73, which also carries a combined spur and bevel gear-wheel 74. The straight or spur teeth of the latter engage similar teeth of a pinion 75, attached to one end of a rotary shutter 76', which has its trunnions journaled in bearings 77, 78, mounted oppositely on the inner surfaces of the caslngs sidewalls 16 and 17. This shutter is preferably 'formed of a tube having two of lts opposlte quadrants cut away, as seen in crosssection in Fig. 1, and its speed of rotation,
which is continuous, is such that the other uadrants thereof obscure or cut off the light-rays while the film travels a distancecorresponding to the angular movement of the flat sides of the prismatic roller 36. The form of shutter here .described is quite suitable, because of its simplicity and effectiveness, though the invention contemplates the use of any other form, of whatever nature, that is adapted to the purpose stated.
Disposed in alinement with the rismatic roller- 36 and the shutter 76, is t e lightfocusmg portion of lan objective-slide 82, carrying the usual reduction lenses for casting an image of diminished size uponthc film 50. The slide 82 is operatively maintained edgewise between parallel guides 83, 84:. A vignette plate 85, offset to one. side so as to clear the shutter 76, is carried by this slide, and translated with it by means of a screw 86which is journaled in bearings 87, 88, projecting inwardly from the opposite side walls, 16, 17. An arm 89, having a fixed jaw' 90 curved over the screw 86 with a slight clearance therebetween, and a movable-jaw 91 hinged to 90 as at 92,-afiords an operative connection between the objective slide and the said screw, the hinged jaw being formed with threads adapted for engagement with corresponding threads on the screw, when vplaced in the position illustrated in Fig. 1.
' locked position. At such times as it is desired to move the slide 82 quickly, irrespective of the screw 86, the spring clip 93, which is suitably formed so as to constltutealso a finger grip, is swung outwardly in order to disenga ge the movable lower jaw 91 from the threads of the screw. One end of the latter carries a sprocket-wheel 94, which is connected up, by a chain or link belt 95, to the before-mentioned sprocket-wheel 70, on the intermittently-operated spindle or countershaft 68. The arrangement is such' that when the screw 86 rotates, the lens or objective carrying slide 82 is translated in predetermined synchronism with the advancement of each image taken on the film 50. While this is the mechanical connection at present favored ,for operating the lens transverse from the main drive, nevertheless it will be readily perceived that other operative connections, either direct or indirect, may be substituted for the one herein illustrated.
To shut out all light from the casing, excepting what enters into it through the objective, a, flexible screen, for example an opaque curtain 96, is fastened. at its middle portion to the slide 82, in such a way that it permits the inner lens holder thereof to project through, while its ends are arranged to wind alternately upon spring-actuated rollers 97, 98, to which they are attached. Mounted in this manner, the curtain will be automatically wound and unwound from the opposite ends thereof, as the objective is being translated in one direction or the other. The side edges of the curtain are caused to follow closely the adjoining opposite edges of the partitions 21 and 22, which co-act with the curtain in precluding the light, that flows in across the front opening 13, from reaching the interior of the casing and the film exposed therein, otherwise than through the objective. A single and flexible curtain is here spoken of, but it` will be obvi- 115 ous to experts in this art, that any duplication or manifolding thereof and any structural change therein not impairing its capability to discharge the function above expressed are contemplated by the present in- 120 vention. s
Strips 99, of opaquematerial, preferably resilient are attached across the bottoml 30, and lid 31, respectively so as to stand vertically against the side Wall 17 and partition 125 l18 of the casing when the holder is inis secured and from which all motion to drive the various mechanisms originates, can be turned either by a hand-crank 100, or by means of a co-acting bevel pinion 101, fastened to one end of a divided shaft 102, which is journaled in bearings. 103, projecting from the inner face of the side wall 16 of the casing. The shaft 102 carries at its other end a miter-gear 10i, in mesh with a co-acting miter-gear 105, correspondingly positioned on another shaft 106. The latter also carries a bevel-pinion 107, 1n meshing engagement with a bevel-gear 108, rotated by a spring-motor 109. Another bevel pinion 110 meshes also with the bevel-gear 108 and is driven thereby, the latter-named pinion being fixed to one end of a shaft 111, which is journaled in bearings 112, 113, fastened to the bottom wall 11. A collar 114, fixed to the shaft 111, has attached thereto a plurality of weighted spring-arms 115each by one end, the other ends whereof are connected with and serve to draw a collared ldisk 116, slidable on the opposite extremity of said shaft, and cause it to contact with a, friction button 117 on said bottom wall, when the speed of the bevel-gear 108 becomes excessive.
The winding of the spring-motor can be effected with a key 118,` or by the handcrank 100 as either is most available for the purpose. Where it is deemed advisable to throw the spring motor 109 out of gear with the manually operated drive mechanism, a clutch 119 mounted on the divided shaft 102 is opened by means of a handle 120 extending outside of the casing. It is likewise optional to use the forms of gearing shown between the 'spring-motor and the main drive, and again between the motor and its speed-governor, or to resort to other means of transmitting and regulating the motion, as may be preferred.
In the operation of the apparatus, the nlm-holder 25 is first charged. This is done preferably ina dark room, by removing the lid or cover 31, causing the rolls 36 and 37 thereon to approach each other, slipping the endless film belt 50 over said rolls while thus approached, and then releasing the yieldable frame 38 so as to place a suflicient tension on the film to offset any variation in the length thereof, care being taken that the marginal perforations 51 properly engage the teeth 52 on the prismatic roller. Next, the film, held firmly in place from the under side of the lid, is inserted into the body of the holder, and the lid itself is applied to the rim of the latter, the spring catches 33 serving to keep the various parts securely bound together. The operator may carry several holders, each charged in the manner just described and the same will be inserted lby him through the door 15 into the compartment reserved therefor within the casare equal -to the advance thereof, as produced by the angular movement of the prismatic driving roller, rotated by any desirable means,-z'. e., whether by the hand-crank 100, or the prime mover 109, or through other agencies. If the self-contained springmotor hereinabovedescri'bed be employed, the operator will be enabled to hold the entire apparatus 'in hand and support it directly on his own person during its operation, without danger of losing or disturbing the s teadiness and regularity of motion requlred. During the intervals of time when the advance of the film takes place, the shutter 76 obscures the light from the objective. Simultaneously, the screw 86 propels the objective carrying slide 82 a predetermined amount, so that the next image cast over the film will be offset or sidestepped from the preceding one thereon, in such a manner that all the images will follow one another in combined helical and side-step formation around the surface ofthe web 50, as indicated in Fig. 6. The webs sensitized surface may thus be covered with a continuous set or series of images or pictures, adapted both individually and collectively for an ideal presentment, in their true positions, of the moving and other objects photographed. The length of the films surface is gaged in accordance with the course of the objective slide in one direction. When the slide 82 has traveled the full length of the threaded portion of the screw 86, it is swiftly returned to its starting point after the movable jaw 91 of the arm 89 has been swung away from engagement with the screw, which enables the slide to be freely moved. Another set of pictures, which may be a serial continuation of the previous one taken, may be collected on another film, substituted for that already lled. The very act of taking out of the casing the holder containing the film covered with pictures operates to close'the sliding door 57 thereof, since the ledge 60 of the latter strikes against the upper end of the partition 20 while being drawn outward,
thereby shutting the said sliding door, whereupon the holder can be slightly raised above the fioor 19 and removed through the hinged back door 15, to make place for the jinlsrtion of another charged with a fresh mova le film, an objective arranged to travel It will be observed that the four comparti other so as to form three L-shaped divisions,
respectively designated by the reference characters B B1, C C1, and D D1, in Figs. 1, 2 and 5. The first? division B B1 contains the film-holder and the driving mechanism. The second division C C1 is occupied by the power transmitting gears and also the driving mechanism, C1 thereof being the same as the section B1 of the first division. The third division D D1 incloses the. motor and the power transmitting gears, its section D1 being the same as thesection C of the second division. This mode of dividing up the casing is productive of great compact-v changes are within the pale of the invention;
and the right to effect the like is hereby reserved. I
