To ZZ 072cm it may concern y Be it knoivn that 1, JULIEN Tessina. a citi- Zen of France. residing in the city oit Philadelphia. county of'v Philadelphia, and State ot' Pennsylvania. have invented certain 1inprovements in Motion-Ficture-Frinting Machines. of 'which the following is aA specioation.

1n motion picture photography. dierent parts of the saine subject are very commonly photographed at different times or under different conditions. so that different sections of' the negative film are subjected to different exposures and have different densities which must be corrected or compensated for in printing the positives from the negatives in order to have uniformity in the projected pictures.

1t is the leading object of my invention lto provide a printing machine ivhich is adapted to be adjusted initially and to be automatically operated so that the .light used in printing will be proportioned to the density ot' the film section and the positive produced vvill be uniform in character, to the end that printing` may be eli'ected ivith iinproved results aiid ivithout the loss'of time that has heretofore obtained.

ln the accompanying di'aivings. Figure 1 is a sectional elevation of a printing machine embodying my invention: Fig. 2 is a part sectional front elevation of the same with parts broken away and the front of the cases removed; Fig. 3 is an elevation of the revoliible light disk provided vvith slides for regulating` the amount of light passed for use in printing; Fig. l' is a broken sectional vieu' taken on the line .l-l of Fig. 3'; Fig. 5 is an enlarged vieiv taken on the line 5&5 of Fig. 1; Fig. G is a vievv of details partly in section taken on the line 6 6 ot' Fig. 5;"

Fig. 7 is an enlarged sectional vievv taken on the line T T of Fig. Q; Fig. 8 is an enlarged sectional view taken on the line 8 8 of Fig.

1: Fig. 9 is a vieiv of a cam Wheel and con-` nections from the section line 9-9 of Fig. 7 Fig. 10 is avievv of a section of film adapted to be used with my improvements; and Fig. 1l is a vieiv of a dial for indicating theposition of the apertured disk for regulating the amount of light used. n

The mechanism. as illustrated in the drawings. comprises the case or housev 1 which knaled in bearings el() on the plate l5.

which is draivn therefrom over the rollers i and 5, and the spool 6 for the negative film T which is drawn therefrom over the roller 8. the films passing .from the rollers through the aperture 9 in the bottoni of the case. case or house 10 supports the case 1, contains atop aperture 1l ivhich registers vvith 'the aperture 9 and is provided With a bottoni aperture 12. the films being dravvn fi'om'the spools, over the rollers and through the apertures inthe operation of printing.

A. trame 13 is contained in the case 10 and has the door 1l hinged on its front plate l5, the films passing betvveen the plate and the closed door in the operation of printing.

An arbor 18 is journaled in the frame and has fixed thereon the wheels 1T and 18, the latter being provided ivith the light apertures 18 and driven by a belt 19. As the vvheael 1T revolves, a cani 20 thereon reciprocates the yoke 21 vvhich is controlled by the vertical guides 22 and 79' and provided vvith the laterally projectingbearings or lugs Q3 for engaging the periphery of the cani. A yoke 2l is carried by the yoke '21. engages the peripheral cain of the vfheel 1T and carries the pins 26 which engage the perforations T along the edge of the films to feed the latter in a ivell knoivii manner, the shutter wheel 18 cutting o the light when the films are moving and passing light when they are at rest. f

A lever 2T has the fulcrum 28 on the frame the pin 34: and connected by a vlink 37 withV an arm 38 fixed on a shaft 39 which is jour- A shoe -ll is fixed on the shaft 39 and provided yvith the toes -lwhich ride on the edges of the negative film, over the perforations T', but drop into the slots/7 formed in a pre-k determined inanner'in the edges of film sections of different densities, the member 1 being rocked by the spring and the intermediate lmechanism when the odset section ot thelcanji 25 registers with the roller 29. il! hen it is desired to hold this mechanism out of operation, a dog e3, pivoted on the plate 15, is engaged in the notch 44 of the link 31.

A shaft 45 is j ournaled in the

bearings

46 and 46 and has the arms V47 and 48 fixed thereon. vAn arm 49 is pivoted on the arm 47 and is further connected with a laterally extending projection on the arm 47 by a coiled spring 50, the latter passing through the arm` 47.

The wheel 18 is provided with a roller or rolling cam 51, adapted to engage the arm 49 and cause it to rock the

arms

47 and 48, and with a cam52 adapted for throwing the arm 49 away from the roller into engagement with the catch 53 whichis pivoted on the bearing '54 and normally held against the stop'55 by the spring 56.l A coupling 57 is pivotally connected with the catch 53'by the `pin 58 and with the link 59 by a, pin 60 disposed transversely to the pin 58; and a coupling 61 is pivotally connected with the link by a pin 62 and with 'a rocker arm 63 by a pin 64 disposed transversely to the pin 62. The arm 63 is j ournaled on a pin 65 on which it is held by a collar 66, the pin being movable in the bearing 54 and supported by a knuckle 67. A coupling 68 is pivotally connectedv with 'the knuckle 67 and with an angular block 69 which is pivoted on a lever 70. Thelever 70 is pivoted at one end on the bearing 71 and at its other end engages a seat 72 on one end of a lever 73, the other end of which is pivoted'on the bearing 74.

The lever 73l rests on the roller 27 on the top of the lever 27,` the former lever having the steps 7 3 and 7 3" Which'engage the roller 27 -in the different positions of the lever 27. Y

Zhen `the` cam 25 rocks the lever 27 against the action of the spring 30, so that the ltoes 42 are 4'drawn back from the film 3, the step 73 is engaged by the roller 27 to hold thelevers n7 3 and 7 0,together with the members 69, 68 and 63 in -their elevated position, so that the cam 75 on the wheel 18 clears the arm 63. When the 'cam' 25- has turned so that its offset section permits the spring 30 to rock the lever 27, the roller 27 .can be swung ,under the notch 73, whereupon the levers 73 'and 70, `together with the members 69, 68, 67 and 63 fall and the arm 63 is held in the path of the cam 75. When the cam 75 engages the arm 63,

the latter is rocked and acts through the intermedlate parts to draw back the catch 53, whereupon the spring pulls the arm i 49 into position to be engaged by the roller carriage and acts to draw the former down,

it being elevated by the rod 79. The rockeris provided with the pawls 83 and notches 84 adapted for engaging trundles 85 of the lantern wheel 85 carried bythe spindle 86 which is journaled. on` the carriage 81, the wheel being revolved stepl by step by the oscillation of the rocker which locks it in its successive positions.

The spindle 86, which carries the wheel 85, has fixed thereon a disk 88 containing radial slots 89 and guides 90. In these guides are movable slides 91 having radial slots 92 of varying size corresponding to the numbers 1 to 12 thereon, the slides being held inposition by

studs

93 and 94, the latter supported by springs 94" so as to be movable away from the slides.

The disk 88, which is adapted to be turned intermittently by the action of the arm or lever 49 through the related mechanism described, is also adapted to be operated by ahandflever 95 having the fulcrlun 96 and connected with the arm 48 by a link 97. The lever 95 is connected by a link 98 with a double toothed pawl 99 which acts on the trundles 100'of a, dial 101 which carries the lnumerals 1 to 12 arranged in correspondence with the like numerals on the disk 88.

Theca-rriage 81, movable on .ways 102, is moved by afrack 103 thereon which is engaged by a pinion 104 fixed on'a journaled shaft 105. The shaft has an indicating arm 106 fixed thereon, movable over a fixed dial 107 and adapted to be fixed thereto by the clamp screw 108 which passes through the slot 109i'n the dial. A lamp 110 is mounted Onithe carriage 81, being movable on the ways-111 thereof relatively to the disk 88. The lamps light aperture 112 is in line with the disk 88s top aperture, which is at rest in a vertical diameter of the disk, and with the aperture 15 in the plate 15 over which the films are moved intermittently. It will be understood that the adjustments of the carriage 81 and the lamp 110 permit compensation to be made for variations in the candle power of the light used for printingv and that the light apertures of the disk cut off light so that the same shall be proportionate to the densities of the film sections previously arranged and perforated.

The hn 7 having been madefup by combining sections of different densities, such film is arranged on the spool 6 and drawn therefrom as the blank film 3 is drawn from the spool 2, the two vpassing between the door 14 and the plate 15, past the light aperture 15. l

In order to initially adjust the mechanism for accommodation to the densities of the negative, the hand lever 95 is operated to turn the dial 101 (through the action of the parts' 98 andy 99) and the disk 88 (through the action of the

parts

97, 48, to, 7G, 77, 78,

79, 80, 85, and 86) until the numeral displayed at the top of the dial indicates that the desired light aperture of the disk is in line with the lamp aperture 112.- l`he apparatus being thus adjusted, the films hold the toes -12 of the member l in their retracted position and the member all acts (through the

parts

39, 38, 37, 3G, 34e, 33, and 31) to hold the lever 27 in the position shown in Fig. 7, where the roller 27 engages the step 73 and holds in the elevated position the

parts

73, 70, o9, G8, G7, and o3. lilith the mechanism-in this position, the arm -l-9,'

- the shutter wheel 18.

'W hen a lm section of diderent density passes under the toes a2, the latter drop into the slots 7 simultaneously with the registration of the offset part of the cam 25 with the roller 28, whereupon the spring 30 throws the lever 27,; the roller 27 is moved from the step 73 to a point below the step 73; the part 73, together with the parts connecting it with the arm o3, drops so that the latter is brought into position to be actuated by the cam 7 5, and the arm 63 is caused to act through the intermediate mechanism on the latch 53 to release the lever 49. rlhe spring now draws the lever 49 into the path of the roller 51, which causes the lever to rock the arm 47, whereby the disk 88 is turned, as previously described, to present in front of the lamp the next light aperture adapted for passing the light required for the particular density of the film. lt will be understood that the slides 91 have been arranged initially insequence so that each forward step of the disk 88 will present a light aperture corresponding to the density of the negative section which `is being transferred to the positive film.
