MOTION-PICTURE-TEANSPOSING APPARATUS.

Specification of Letters Patent.

Patented Mar. 25, 131%.

Application filed November 16, 1816. Serial No. 131,680.

To all w hom it may concern Be it known that I, GIANNI BETTINI, a subject of the King of Italy, residing at Paris, France, have invented certain new and useful Improvements in Motion-Picture-Transposing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to motion picture transposing apparatus, that is to say, to an apparatus for converting a series of motion pictures from one form or arrangement to another. More particularly, the invention is directed to the transposition of a series of motion pictures arranged, as usual, in a single row or strip into a difierent form of record, for example, one having a circular or spiral or a parallel-row arrangement of pictures. The usual strip record may be a negative, and may be used for printing or producing positives of the spiral or other forms mentioned, and obviously the operation may be reversed, namely, by transposing the spiral or other form of special record into the usual or strip form.

The general objects of thepresent, invention are to afford a transposing apparatus of superior efficiency in operation, simplicity. strength anddurability in construction, free from vibration and other factors of uncertainty, and such as will print the pictures in the exact positions requisite, and clear in outline and detail. Other and more particular objects and advantages pertaining to the invention will be elucidated in the hereinafter following description.

To the attainment of such objects and advantages, the present invention consists in the noval apparatuses, combinations, arrangements, devices, details and other features herein illustrated or described.

I will first describe two different embodiments of the principles of this invention, and will thereafter point out the features of novelty in the claims.

In the accompanying drawings, Figure 1 shows what may be considered a side elevation of a transposing apparatus embodying the present invention, the front of the machine being at the right, the rear at the left. The mechanisms seen in this view may be employed for themaking of different forms of records, spiral, parallel-row, or other form.

Fig. 2 is a rear elevation, with certain parts omitted for clearness, of a plate shifting mechanism adapted to be used in cooperation with the mechanism of Fig. 1 for transposing the pictures of an ordinary strip record into a spiral arrangement. Fig. 3 is a section tel-zen on the plane 3-3 of Fig. 2.

Fig. 1 is a front elevation with certain parts omitted for clearness, of a plate shifting mechanism adapted'to cooperate with the mechanism of Fig. 1 forthe production of records having parallel-row arrangement of pictures. Fig. 5 is a section taken on plane 55 of Fig. 4. Figs. 6, 7 and S are similar left hand elevations showing certain of the parts of'Fig. at in three different positions. Fig. 9 indicates the form of record resulting from the employment of the apparatus shown in Figs. 1 and t to 8; Referring first to the apparatus for pro ducing records of spiral form, this being shown in Figs. 1, 2 and 3, tne mechanism is shown as supported by a convenient table 10. Mounted in suitable bearings above the table, is a horizontal shaft 11 which drives or controls the various parts of the mechanism. As will be seen, this shaft serves to operate the devices which feed the nega tive strip record with a step by step motion, and also the devices which shift the circular sensitive receiving plate, and also operates the optical shutter which opens when the strip and plate are stationary, and closes during their shifting movements.

The drive shaft 11 may be-turncd in any desired manner, for example, by an electric motor 12, which may be controlled in speed by an electric controller 13. Manifestly the speed of the apparatus must be regulated so as to insure the proper exposure of the plate. Y

At the rear of the apparatus is shown a 15. This may contain the of whatever form is used, and the mechanism for shifting .it intermittently so that the plate may successively receive photographic impressions through an aperture in the front wall of the box. The mechanism. within the box may comprise an outwardly extending operating shaft 16, geared to the drive shaft 11 by a pair of engaging bevel pinions 17. The details of the mechanism within the box 15 will be later described in connection with Figs. 2 and 3.

An ordinary negative strip 19 of motion picture film is shown as being run off from light-tight box sensitive plate a first reel '20, and coiled up upon. a second ating shaft 24, which is shown as connected to be driven by the drive shaft 11 of helical gears 25.

by a pair By the described arrangement, one rotation of the drive shaft 11 gives one rotation of the operating shaft 24, so as'to advance the film to the extent of one picture, and in the same period the operating shaft 16 of the plate shifting mechanism is given one rotation, and. as w1ll be seen, this causes the plate to advance to the extent of a single picture.

The usual auxiliary devices of film feed ing mechanisms may be employed. For example, a gear 27 driven from the shaft 24 may operate a slip drive 28 to advance the reel 20; and the receiving reel 21 may have a resilient or other take-up device.

' The optical parts of the apparatus include a lantern 30 directed toward the rear, and an objective 31 between the lantern and the box 15 containing the sensitive plate. The arrangement of lenses may be such as to conveniently reduce the size of pictures. A shutter 33 is shown between the objective and the box 15, this shutter being rotated by a shaft 34, which, in turn, is driven from the shaft 24. The traveling motion picture strip 19 and the rotating shutter are both arranged in the path of the light rays as described, with' the result that whenever the shutter is open an exposure is produced and an image of one of the pictures on the film is projected on the sensitive plate within the .box 15. Any suitable precautions may be adopted to protect the sensitive plate from undesired exposure to light.

When it is desired to make the spiral arof light to be focused into an image on the sensitive plate. The box also has an outwardly extending wall 38. The

walls

36 and 38 support the mechanism to be described. The rear wall or cover 39 is removable and is substantially omitted from Fig. 2 to better disclose the interior.

The carrier disk 40, forming apermanent part of the mechanism is partly indicated in Fig. 2, its position being indicated by a broken circle. This disk is located betweenits actuating mechanism and the rear cover. The disk has a plurality of apertures or windows 41, each one of a substantially square form, and all the windows formin a series spirally arranged around the dis The disk may be made of sheet metal and the windows'formed by striking tongues 42 of metal forwardly therefrom, the tongues being left projecting forwardly for certain purposes.

The disk 40 is intended to rotate and for this purpose is mounted on an axle 43. The disk is also intended to have a horizontal feed to secure the spiral arrangement, and

for this purpose the axle is mounted in a slide block 44, which may slide longitudinally in a slotted guide piece 45, mounted on the front wall 36.

The forwardly projecting tongues 42 of the disk 40 form aspiral series, and are sufficiently continuous to substantially form a flange which may be used for guiding purposes. The flange formed by the tongues 42 is adapted to cooperate with a fixed guide 47 projecting rearwardly from the right hand end of the guide piece 45, see Fig. 3. As each of the windows 41 comes into exposing position opposite the aperture 37, its struck out tongue portion slides over the fixed guide piece 47. In this way the disk is properly relatively positioned during its progress, and as the disk turns around and around, the spiral arrangement of the tongues causes it gradually to feed bodily toward the right in Figs. 2- and 3. It is shown as having been already fed. partly toward the right. In order to hold the tongues '42 in contact with the guide piece 47, I have provided a resilient device tending to restrain the disk and hold it toward the" left. This consists of a push bar 48 pivoted atits lower end, its upper end pressing against the axle 43 of the disk, and a spring 49 tending to pull the parts toward the left as shown.

It will be understood that the disk 40 is intended to carry at its rear face, a sensitive disk 50 which is to receive the pictures. There may be a notch-and-finger device 51 for properly relatively positidning the disks and a central locking nut 52 for securing them together.

If the disk 40 be now rotated toward the right, its spirallyarranged tongues in cooperation with the guide 47, will automatically causeits gradual feed toward the right. It, therefore, only remainsto describe the means for giving intermittent rotation to the disk. Its rotation should be stopped for a brief period while each successive window stands in line with the optical apparatus.

For this purpose, I have made use of the same struck out tongues 42. These are adapted not only to form a spiral guide as explained, but are adapted to constitute a spiral series of teeth, by which the disk may be conveniently driven. For so engaging the teeth 42, there is shown a pinion 54: between the disk and the front wall of the box. The

teeth of the disk and those of the pinion -will, of course, be suitably shaped to cooperate with each other on this rotary shifting action. The pinion 5 1 may be driven from the drive shaft 11 of the machine by the following connections: The drive shaft 11, by a pair of bevel pinions 17, rotates the The shaft'57 carries a pinion 58, engaging a gear 59 on a shaft 60, which extehds to-- ward the center of the box, and there carries the pinion 541 which directly engages the teeth 42 of the carrier disk.

As the parts areshown, one rotation of the

shaft

11 or 16 sufficient to shift film strip 19 one picture-causes a quarter rotation of the shaft. 57, or one-twelfth rotation of the shaft 60. The pinion 54 having twelve teeth, the disk 40 is advanced to the extent of a-single window or picture on each rotationof the main drive shaft 11.- It follows that when th apparatus is in full operation, each picture on the strip film 19 is projected through one of the'jwindows 41, and exposed on the sensitive plate during a part of each r0- tation of the drive shaft but while'the film strip and sensitive surface are momentarily.

stopped, following which the shutter 33 closes, and, while closed, both the spiral disk and the filrn strip shift to the extent of one picture, whereupon the succeeding picture is projected through the successive window of the disk; and so on to the end of the series.

The modified form of apparatus is for transposing a series of pictures-from a? strip or single line film into a record with an arrangement having a. plurality of substantially straight, parallel rows of pictures. This modification is shown in Figs. 1 and i to 8 inclusive, Fig. 9 illustrating such a record. 1

The means for operating a negative film and the means extraneous to the casing in which the sensitive record sheet is to be arranged correspond substantially with the mechanism shown in Fig. 1, and partly in Fig. 2. In Fig. 1 there is the main drive shaft 11, which makes one rotation for the exposure of a picture, and the inter-meshing bevel pinions 17, by which the drive shaft 11 rotates operating shaft 16, which extends into the casing for the sensitive surface or plate. In Fig. 4 and the following figures the light tight box 15 of Fig. 1 is omitted, except that there is shown in dotted lines a fram or support 15 for the mechanism within the light tight box, which will have an aperture in its front wall for the admission of the optical image The rectangular sensitive plate, or plate having a rectangular sensitive field which may be converted into a record such as shown in Fig. 9, is supported by the apparatus of Fig. 4, etc., in any convenient manner upon a carrier 13*.

It is intended that-this carrier 13*, which may be of any suitable construction, to

gether with the sensitive plate, be given certam step by step motions vertically and laterally so 'as to successively bring different portions of the plate into'exposing position.

f desired the sensitive plate may be faced by an opaque member having apertures or wmdows corresponding in position with the imsliges to be produced, but this is'not essen- [tia The mechanism of Fig. 4: etc., about to be described, 1s for the purpose of transmitting motion from the operating shaft 16 to the carrier 13 so as to intermittently advance the same, while other parts associated with said carrier are adapted to drop the sensitive plate to a lower level, said icarrierwith said plate then advancing reverselyv along the second row, and so on, until a rec- 0rd plate is produced, substantially as in Fig. 9. The step by step advance is indicated on said Fig. 9 by letters Z, m, n, 0', p,

Referring to Fig. 4 it will be seen that there is shown a pair of bevel pinions 17,

corresponding with the bevel pinions 17, op-

erated by the main drive shaft 11, as in the first form of the apparatus, and that'pone of these pinions is mounted upon a shaft 4*.

Said shaft 4 carries a gear wheel 5 which is in constant mesh with two similar wheels 6 and 7, on which gear wheel 6 is keyed to a horizontal shaft 8 while the gear wheel 7 is loosely mounted upon a shaft 9 A clutch-10 is also mounted upon shaft 9 whereby to clutch the gear wheel 7 to said shaft. Shaft 8 through internlediate and other mechanism, is adapted to impart a step by step shifting movement to the'carrier 13 and hence to the sensitive surface.

supported thereby, such shifting movements causing the plate to be shifted along the length of one row, of picture receiving portions on the sensitive surface. while shaft 9 and mechanism associated therewith shifts the surface from one row of picture receiving portions thereon to the next, as from n to 0, Fig. 9.

The shaft 8 is mounted in suitable bearlugs on the frame or'support for the mechanism of Fig. 4, and is provided with a cam 11- of suitable length, which cam is straddled by stirrup-like or double pawl 12, which is shown in Figs. 4 and 5. This stirrup-like double pawl can oscillate freely in a direction transverse of the cam shaft 8 it being mounted upon a sensitive plate carrier 13 before referred to. Said carrier is mounted upon and guided in its movements by a pair of parallel guide bars 14, 14?.

One arm or pawl 16 of the stirrup-like device 12 is arranged in cooperative relation with a rack bar 17 which is fixed rigidly to the supporting frame. Said pawl 16 is of such thickness that it can, under the influence of the cam 11*, enter and exactly fit in the notches of the rack bar 17*, thereby rendering the stirrup device 12 immovable laterally and locking the plate bearing carrier 13* in the position as set by the said pawl 16-. It will be understood that the distance between the teeth of the rack bar 17 corresponds with the approximate length of each single picture area on the sensitive surface. The other pawl 15 of the stirrup device 12 is located in cooperative relation with the teeth of a rack bar 18*, which is similar to the rack bar 1'7 but is arranged so that it can be moved longitudinally. Rack bar 18 is mounted in suitable supports, as 19 by which it is guided in its movements.

Rack bar 18 is'provided with a longitudinal extension 20", which terminates in a nose or lug 21*, which engages in a peripheral groove 22 of a cam 23, which is loosely mounted upon'shaft 4*. Cam 23 can be rigidly connected with shaft 4: by means of a suitable clutch 24 which is controlled by a fork 25 suitably pivoted to the frame of the apparatus, and p ovided with a pin 26 which engages in a suitable slot or groove 26 in a lever 27. Said lever is pivoted at 23 to the frame of the apparatus, While its free end 29 is suitably shaped so that it may be maintained by means of a spring 29 in constant engagement with a cam 30. Cam 30 turns on a suitable center support, together with a large gear wheel 31 which is in constant mesh with a small pinion 32, which is keyed upon the shaft of a bevel pinion 33 which is in mesh with a second cam 37, which notched at 38" at a point approximately opposite the high point of the cam 30". The free end 39" of a lever 40 travels upon the notched edge of the cam 37 said lever being pivoted to the frame of the apparatus at 41 and suitably connected with the clutch 10 which is arranged upon beforementioned shaft 9. Said clutch 10 is pressed toward the gear wheel 7 by means of its operating spring 13". Shaft 9 is provided with a cam 12 similar in conformation to the cam 11 and is adapted to control the movement of the plate to receive photographic impressions to another row after said plate has received such impressions on a preceding row. The mechanism controlling this row to row movement is more particularly represented in Figs. 6, 7 and 8, which mechanism is hidden in Fig. 4, and includes a fork 14 which is mounted upon a longitudinally shiftable stem or shaft 4:5 arranged upon the shiftable carrier 13, said fork embracing the said cam 42*. The shiftable stem or part 45 is provided with fingers or pawls 46 which are adapted to enter the spaces be tween teeth 48 of a r ck bar 19 forming a part of the plate carr er frame. This rack bar 49 is shiftable in a direction rectilinearly of the direction of movement of the carrier 13. The fingers or pawls 46* are rigidly connected to a sleeve 50 which is adapted to oscillate on the shiftable stem or part 45, and this sleeve is controlled by the lower end of a swinging lever 51* which is pivoted to the stem 45 at 52"-, the other end of this lever, when in the position of rest, touching the shaft 9 42 in the position shown in Fig. 6.

The plate or sheet having the sensitive surface for receiving the images of the pictures on the film such as 19 of Fig. 1, is held in the carrier 13 by means of suitable springs which are not shown, but may be of any suitable construction and arrangement to prevent any movement of the sensitive surface except the controlled movement.

The operation of this modified form of the invention for producing records somewhat similar to that shown in Fig. 9 is as follows:

The movement transmitted to the shaft 11 in turn transmits motion to the bevel pinions 17, causing the pinion on the shaft 4 to rotate at the same speed as the gear wheel 25 which controls the film apparatus. The shaft 45* transmits its motion to the gear wheel 5 and from that to the gear wheels 6 and 7 the gear wheel 7 occupying the position shown in Fig. 4:, ordinarily turns loosely upon the shaft 9*, owing to the clutch 10? being removed therefrom, while the gear wheel 6* imparts its rotating movement to the shaft 8 which turns at the same speed as the gear wheel 25, Fig. 1.

Supposing that the frame 49 with the rack teeth is positioned as indicated in Fig. 4, with the sensitive plate set thereon and held in the carrier 13, and that the shaft 8"11 is rotated so as to impart an oscillating motion to the double pawl 16*. If the pawl 16 has been moved by the cam 11 so as to be engaged in one of the notches of the stationary rack bar 17, the result is that all the allied parts are held immovable during the momentary opening of the shutter device such as shown in Fig. 1, and a picture upon the film is then projected upon the sensitive plate. The cam shaft 8 -11"-, continuing its rotation, brings the double pawl into the position indicated in, Fig. 5, thus releasing the pawl 16 from the rack bar 17 a and causing the other pawl 15 to be engaged in one of the notches of the shiftable rack bar 18*. Inasmuch as the lug 21 of the rack 18 is engaged in the cam groove 22, said rack bar will receive a reciprocating movement at each rotation of the cam wheel 23, the cam being so proportioned that it will shift the rack bar 18* equal to the width of one image. The consequence is that the shiftable rack bar 18 and its associated double pawl gives a lateral displacement to the sensitive plate equal to the width of one image, so as to shift the plate to the next position to receive a new image at the next I picture receiving portion of the sensitive surface of the plate. A slight oscillation of i the double pawl toward the stationary rack opposite the high bar 17, brings the pawl 16 into engagement with said rack bar 17 for the next impression on the sensitive surface, after which the other pawl 15 of the stirrup device 12 is brought into engagement with the next notch of the shiftable rack bar 18 for another displacement of the carrier and sensitive plate, and so on. This operation is gone over fifteen times for a plate designed to receive sixteen rows of images. It is clear that during the described displacement of the plate in the direction of a row of image receiving portions of the sensitive surface, the

cams

30 and 37 will simultaneouslyrotate by means of the shaft 8*.

The pinions 34 and 33 being in the ratio of 1 to 2, while the pinions 32 and 31 are in the ratio of 1 to 8, the result is that the cams 30*, 37 make one turn for sixteen turns of the shaft 4*, which is operated by the main drive shaft, before described. The movable rack bar 18 therefore, gives fifteen step by step movements to the sensitive plate, and then, when the pawl 16 of the stirrup device is in engagement with the last notch of the stationary rack bar 17, the high point of the cam 30 acts to-raise the end 29 of the lever 27 while, on the other hand, the end 3950f lever 40 enters the notch 38 of the cam 37 which notch is diametrically point of cam 30. The

lever 27, now being shifted toward the rlght by the action of the cam 30, disengages the clutch 24 from the cam\23; thus leaving 1t loose upon the shaft 4, while the detent 36 is moved by the action of the link 35 so as to draw the operative end of the detent into engagement with one of the notches or openings, not shown, of the cam 23 The cam 23 is thus locked, and the rack bar 18 is held stationary.

Simultaneously with the operation of the lever 27 and concomitant parts, the lever 40*, which is pushed back b the spring 43, causes the clutch 10 to ecome engaged with the gear wheel 7 which is mounted loosely upon the shaft 9; As the gear wheel 7 is now rigidly clutched .to the shaft 9 1a rotary motion is imparted to the gear wheel :7 and shaft 9 through the medium of the intermediate gear wheel 5*. The cam 42 is shown in its raised position in Fig. 6, but as soon as it begins to rotate by the action of its shaft 9 it acts upon one of the proections 44 so as to bring said projections 44 into the position shown in Fig. 7, bv causing the frame 49 to shift a distance corresponding with the height of one image. At this moment the cam 42", continuing its rotation as shown in Fig. 8, bears upon the end 53 of the lever 51*, thereby moving it into the position shown in said figure. This causes a partial rotation of the sleeve 50 and the oscillation of the fingers 46?. which thereby become disengaged from the notches of the rack bar or carrier frame 49. The

' sensitive plate is then held immovable in the carrier 13 by the beforementioned springs. and the cam 42*, continuing its rotation, withdraws from the lever 51, which returns to the position shown in Fig. 6, while this cam, acting upon the upper branch of fork 44, carries the latter again into the position shown in Fig. 6. The cam having now made a complete turn, the fingers 46 move back into the notches of the rack bar or frame 49*, through the medium of suitable springs, not shown, and the cam 37 having continued to rotate, again raises the end 39 of the lever 40 in order to bring back the clutch 10 into the position shown in Fig. 4, so that the rotation of the cam 42 is discontinued.

At the same time, the high point of the cam .30 has passed the end 29 of the lever 27 and the latter is brought back to the left by the spring 29*. and the clutch 24 is returned into locking engagement with the cam 23*, thereby removing the detent 36 from its interlock with the cam .23. The cam 23 now commences to rotate again, thus imparting reciprocating movements to the rack bar 18, as before described; Owing to the conformation of the c: n 11 and to a peculiar arrangement of the control for the cam 23 and of the gear wheels 5 and 6, the

pawl 15 of the stirrup device l2 is in en gagement with the reciprocating rack bar 18 when it reaches the end of its course to the left, whereas when it reaches the end of its course toward theright the pawl 16 is in engagement with the fixed rack bar 17; As a consequence the first lateral step by step movement received by the sensitive plate, after its shift from one row of image receiving portions to the next row, will be imparted in the direction of the series of step by step movements which are to follow directly after this row to row shifting.

It will be observed that, owing to the proportions of the several gears and pinions, the

reciprocating rack bar 18 is shifted for the distance of one tooth and, therefore, displaces the sensitive plate to the extent of one image or picture receiving portion for each turn of the drive shaft 11 shown in Fig. 1, and consequently for each image which is transferred from the film onto the sensitive surface.

The transmission of movement from the drive shaft to the pinions 17 or 1'? can be effected in such a way as to prevent trans mission of the movement of the drive pinion of the

pair

17 or 17 to its shaft, ii an abnormal strain be produced upon the latter due. for instance, to the presence of some foreign body in the gearing, to the detective position of the sensitive plate, or to any other cause so that the apparatus will come to a stop without becoming damaged.

It s possible to arrange for the transfer of a certain number only of theviews from the film to the sensitive surface instead of all the views. This method of transferring is specially desirable in the case of a moving picture machinedesigned for use as a" toy. it is obvious that the sensitive plates may be of any desired shape, and that the images which are to be photographed thereon can be disposed thereon in any way desired, the surface which is to receive the images preferably having its image receiving portions arranged to move in a direction across the direction of movement of the film which is being photographed. he operation of the apparatus may be ct'fectuated by hand or by means of any suitable motor.

It is obvious that the invention is susceptible of modification other than the two forms of the apparatus herein shown and described and that parts may be omitted, parts added, and parts substituted. without depart ing from the spirit and scope of the invention as covered by the appended claims.
