VAPIPAIRA'JIUS FOB PRODUCING A NIMATED DRAWINGS.

Application led March This,` invention relates to the production of animated drawings of the -general type described in myl prior Patent No. 1,143,542, issued June 15th, 1915.l More particularly my invention relates to the type in which the illustrated action is represented as progressing in respect to the background. The

background is drawn or4 painted on a strip of a length many times greater than the width of the picture to be projected, this strip beingl advanced a slight amount for each exposure or series of exposures ofthe film. Thus the action which is drawn'on sheets separate from the background, is represented as progressing along the scene shown in the background.

The objects which are to be represented as moving are drawn on a series of sheets of translucent material, such for instance as celluloid, and the reverse side of each sheet within the outline of Ythe object, is preferably rendered opaque so that the background does not show through the movable object.

It will be understood that a series of drawings are made showing the movable object in the Successive positions which it occupies in \a cycle of movement, and these yare photographed in succession in superposed relationship to the background. lBy advancing the background each time one of said seriesof pictures is vsubstituted for another, it will be seen that the same cycle of movement may be repeated indeinitely,.but

in respect tosuccessive portions of the backl ground. For instance, a person o rv animal may be represented as running for a long distance, represented by the scene shown in the background, and the number of pictures required is only that necessary in represent- 'ing a single cycle of movement of the running object. v

As one important feature of myA invention I automatically advance.l the backgrounwd sheet each time a substitutionis made of the pictures showing the objectin motion. The effect n the screen after the film is developed and projected, is that the characters aremoving at rapid speed over endless expanses of territory, and have been photographed en route by a motion picture camera which was moving at the sameI speed as the objects.

As a further important feature of my invention I provide means for effecting a relative movement of lthe normal positions of s, 192s. serial' No. 93,369.

sheets of two series, whereby each series may 'show a separate moving object, and one of these objects may appear to approach or recede from the other object, without the necessity of making separate drawings for the objects -in their ldifferent relative positions. v

By means of this feature of my invention two. objects may appear to be moving at rapid speed over an expanse -of territory, l5 and. one may appear to gain on the other although only a single series of pictures is used for the repeated cycles of movement of eachobject.

As the drawings on Celluloid must be ab- 7 solutely Hat While othey are being photographed, to prevent halation, I employ a frame having a glass which may rest on the sheets to hold them flat during the photographing action, and as it is necessary to raise this frame each time a change of drawings is made for a new exposure, I employ such movement of the frame to ac-l tuate the parts which eii'ect the relative movement-of the separate sheetsI and the fbackground.

In the accom anying drawings I have illustrated one orm of apparatus which may be employed in carrying out my invention. It will of course be evident that other forms may, be designed without departing from the spirit or scope of my invention.

In these drawings: Fig. 1 is a perspecti in raised position.

Fig. 2 is a section om the line 2-2 of Fig. 1 but showing the :frame in lowered or photographing position, and

Fig. 3 is a sectinal ldetail of certain of the actuating parts.

In the :form illustrated there is rovided a support 10 on which the sheets to e photographed are placed, and at one side of this support there is pivotallyk mounted a frame 11 havin a glass body portion 12 for ressing the s eets on to the support and ho ding them flat. For making anlmated drawingsv of the panorama type, there 'is provided a strip A which may be of paper or any other suitable material of the proper width, and of any desired length.` This has' drawn', painted, printed, or otherwise formed thereon, the scene which" is to be represented on the screen. The strip may be several feet long, depending upon the extent of the ex- 11 ve view with the frame panses of territory to Ybe shown in the panorama.

The movable object is drawn on a series of sheets, preferably of celluloid, and superposed -on the background strip A. There may be a very large number of these drawings, and successive drawings of a series may show the same movable object in successive poses or positions in a cycle o movement. For instance, if it is desired to represent a man as running there may be a series of a dozen or more drawings made showing the successive positions of the man while taking two steps and completing a cycle of running motion. This same serles of pictures may be photographed a large number of times in succession as the man is represented as taking a large number of running steps while the panorama is being advanced.

If it is desired to representa second moving object, this may be shown on a separate series vot' celluloid sheets and the sheet of each series exchanged for the next sheet of the same series between successive exposures or roup of exposures n the drawing I have shown two superposed Celluloid sheets B and C. The sheet B may have a picture of an animal thereon and there will be provided a series of sheets B showing this animal in the successive poses or positions going to make up a cycle of movement. The sheet C has a picture of a man thereon, and there will be a series of these sheets C showing successive positions or poses in a cycle of running movement by the man. In photographing, one of the sheets B and one of the sheets C, are placed in superposed position on the strip A, and are pressed down and held flat by the glass 12 of the frame 11;

. As one important featureI provide means for automatically advancing the panorama strip A each time the frame 11 is moved into and out of photographing position. This means is illustrated as a pan` of rollers 13 and 14 between which the strip A passes. One of the rollers is driven by suitable gearing from -a shaft 15, and the latter has a' ratchet wheel 16. Any suitable mechanism is provided for turning the ratchet wheel' upon swinging the frame 11. As shown, the frame 11 has a hub 17 connected to an arm 18 which latter is connected by a link 19 to a lever 20 pivoted on the shaft 15. Thev arm 20 has a pawl 21 engaging the ratchet wheel 16. Thus as the frame is raised, the pawl 21 moves over the ratchet wheel, while the lowering of the frame rotates the ratchet wheel and turns the rollers to move the strip A endwise. By ,connecting the link 19 to the lever 18, at various distances from the pivotal center of said lever, the` extent of movement of the strip A for each swin ing movement of the frame, may be varie I have shown the lever 18 as provided with a series of holes, into any one of which the pivot pin of the link-19 may be inserted.

As another important feature, I provide means for effecting the relative movement of the registering means which control the po- .control the position of the latter, and the bar 23 has a similar pair of pins 25 to enter aperturesin the opposite side of the sheet C to control the position of this sheet. By eecting a relative endwise movement of the bars 22 and 23, the position of the movable object on the sheet B may be varied in respect to the position of the movable object on the sheet C. Thus, if these objects be represented as running, flying, swimming, jumping, or otherwise progressing at a rapid rate, either object may be represented as gaining on the other. The means illustrated for accomplishing this relative movement of the bars 22 and 23 is illustrated as a pair of threaded shafts 26 and 27 which extends in opposite directions from the supports to ythe frame 11, and adapted to be rotated in either direction by the swinging of said frame. The shaft 26 has threaded engagement with an arm 28 on the bar 22, while the shaft 27 has threaded engagement with an arm 29'on the bar 23.

Each shafthas a pair of oppositely facing ratchet wheels 30 and 31 and the frame adjacent to its pivotal support has a pair of pawls 32 and 33 for engaging with these ratchets. One of the pawls is of the push type, and ther other of the pull type, and either may be moved into operative position, or both may be held in inoperative position. Thus the swinging of the frame 11 may rotate either the shaft 26 or the shaft 27 in either direction, or may rotate the shafts in the same or in opposite directions. The rotation of the shafts causes a relative movement of the pins 24 and 25 so that each time a new sheet of the series B and a new sheet of the series C are placed in position, the movable object illustrated on the sheet will be in a different sition in respect to the frame 11 which deiies the sight or field of the camera. By moving the two bars 22 and 23 in the same direction, the two Ymovable objects will be progressing across the field of vision of the camera, while by eiecting a relative movement of the bars, one object may be caused to appear to gain on the other. l The frame is so constructed that it may be vclosed with the pins 24 and 25 in any position. As shown, the ...frame has grooves 34 to receive these pins. The mechanism illustrated may be emplo ed to move the panorama strip 11 in eit er direction. For ini stance,'with the strip threaded up as shown, it will be advanced toward the-left each time the frame l1 is moved to closed position, but

by passingv the strip over the upper roller 14, thence across the support and around the roller 55, the end of the strip may be passed back between the rollers 13 and 14,'

so that the portion of the strip which is superposedpn the support 10 will move ^to' ward the rlght, instead of toward the left,-

each time the frame 11 is swung down.

that even if only a single moving object is to be shown, a portion of the object may be drawn on a sheet B, and other portions on a sheet C, and the bars 22 and 23 permitted toy remain atrest or move simultaneously inthe same direction. This making of a p0r- \tion.of the movable object on one sheet and another portion on another' sheet, results in a very great economy. in the amount of drawing required, as is pointed out in my prior Patent No. 1,143,542, above referred to.

Although the whole of the movable object may be vdrawn on each of the series of sheets B, and only a single sheet be placed on the pins 24 at one time, it will of course be evident that I may employ the same method ralityof superposed sheets, one of which p may show the portion of the movable object Which remains relatively stationary, such for r instance as the body of an aeroplane, and

another of which would form one of4 a series showing the aeroplane propeller, a passenger, or otherv object moving relatively to the body of the aeroplane. The samewould apply to the sheet C mounted on the pins 25.

In photographing, there may be two lor more exposures for each setup ofvsheets, or i there may be a change of one or more sheets between each successive exposure. I change the relative positions of the strip A, and 1f desired of the sheets B and C, only between successive movements of the frame 11, even though there maybe a plurality of exposures on the film between successive frame movements.

In referring to the sheets B and C, as being translucent, I' mean to include only such su stantially complete translucency as will permit the picture on one sheet to beseen` through a' superposed sheet. The translucnc should be such that the sheets are near y, if not complete] transparent. The preferred matQi-ial for t e sheets B and C is substantially clear celluloid .from which the ink may .be washed after the' negative film has been made up,.so that the sheets may be reused for another series of pictures.
