JOHN BOY HUNT, OF INDIANAPOLIS, INDIANA.

MOVING-PICTURE- PRINTING MACHINE.

To all whom it may concern.

Be it known that I, JOHN ROY HUNT, a citizen of the United States, and agresi; dent of Indianapolis, county of Marion,j and State of Indiana, have invented a certain new and useful Moving-Picture-Printing Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to print from a negative film of the usual type, a positive film oi novel type, in which the pictures are not arranged in their natural sequence.

Hitherto the films have had the pictures therein arranged in their natural sequence, in other words in the same sequence as they appear in the negative and on the screen... This invention is to print the pictures in a different sequence or relation to each other, but so that with a suitable projecting machine the pictures will appear upon the screeii in their natural sequence.

There are different forms of machines having somewhat different modes of operation for carrying outthis invention. The machine herein shown, to illustrate the general nature of the invention, and which is now believed to be the preferable form, prints the pictures of the different series on the positive film in succession or alternatively. Consequently the machine herein shown has a plurality of, or at least two, display apertures in front of Which one negative film and one positive film passes. But the invention is not necessarily limited to such-an arrangement, as pictures of the series may be simultaneously printed with two or a plurality of apertures, instead of doing it alternately or successively. Nor is the invention limited to the use of a plurality of apertures, as one aperture may be utilized and the film be passed across it a plurality of times, printing the pictures of one series one time and v or the next series another time.

As stated the printing machine herein shownhas' a plurality of display apertures, one a erture for each series of pictures on the li Hi. In the new film the second ic-' ture is located several inches from the rst icture, the third picture is located near the rst icture, and the fourth picture following 199 second picture. In other Words the Specification of Letters Patent.

Patented Oct. 28, 1919.

Application filed February 17, 1919, Serial No. 277,594.

pictures of the two series, either the odd or even numbered series, are spaced apart on the film so that they may be projected through the plurality of apertures in the projecting machine alternately, yet in natural sequence, the first picture being' pro jected through one aperture, and after that the other picture through the other aperture, and after that the other picture through the first aperture, and so on. While the pictures are projected through the apertures alternately. yet consecutively, they are in such order on the film that they will appear in their natural sequence on the screen. The object of this invention is to print such novel type of picture film.

A section of a film as used in this specification means that portion of the film which contains one picture or one blank. It is used in connection with the feeding apparatus which feeds the films two sections at a step.

In the drawings Figure 1 is an elevation of the printing machine with parts removed or broken away to display the mechanism. Fig. '2 is a central vertical section on line 22 of Fig. 1, some parts being broken away. Fig. 3 is a detail view of the upper cam actuated feed mechanism on an enlarged scale. Fig. 4- is a central vertical section through ld ig. 3. Fig. 5 shows the lower feed mechanism with the cam opersame at the time the second picture is he ing printed and the twenty-third picture is moved to printing position.

There is shown herein a machine for printing positive films from negatives. It

lllt

consists of a frame 20 with a motor 21 at hers are given to the pictures, that only for explanation, and the numbers there given are the natural sequence numbers of the pictures on the negative film, so that one can see where'a certain numbered picture of the negative is located on the printed film, but in the commercial article, as pro- I duced, the pictures on the printedfilms are numbered thereon, as seen in Fig. 7 inshort repeated series for convenience. In case the film should. be "torn the operator could. 11l1-- derstand how to adjust his film in the projector better than if the numerals were'consecutive from beginning to the end. Thus the odd numbers in Fig. 7 run from 1 to 11 and the even numbered series run from 2 to 12, and then they are repeated throughout.

Referring now 'to the means tori'eeding the films through the printing machine in the peculiar manner just described, there is seen in 3, secured to the inside surtace er the aperture plate two vertical guide 0.), "a between which a feeding frame 61 ically reciprocates. It has a cross angle bar 32 on its upper end, and another similar her 38 at its lower end. The upper angle liar carries a horizontally slidalole tooth frame 64:, which has a pair of teeth adapted to pri'iject through the feed opening 65 in the aperture plate, and through the lieed holes 66 in the margins of the films, for feeding, the films downward. The feeding tooth 1 Mlle carries a screw 67 which projects through a slot 68 in the angle bar 62 and 35 carries on its lower end a roller 6%) which extends into and travels along a cam groove 70 in triangular shaped, cam 71 keyed onshatt 51, as shocvn in Figs. 3 and 5. This roovo is in two sections ditlerently reto the aperture plate 35, one half of the of said groove, as shown in Fig. 4, located. far away from the aperture ate and then the Oi/lwlllalf thereof as an in 6 being nearer said plate. iere'fore, as the cam revolves it moves the h G-linto and out of engagement with films. While the cam is making a. half revolution the teeth of the frame 64 will be in engagement with the films and will feed them downward for two spaces, that is a distance equal to the width of two pictures, and then the toothframe 64 will be with drawn and travel upwardly again to its former upper position. preparatory to another feeding movement. Since the shaft 51 must extend through the sliding frame 61, a vertical slot 73 is made in such frame, as seen in 3 and 5.

The construction of the lower feeding apparatus, as shown in Figs. 5 and 6, is the same as the upper one shown in Figs. 3 and at, excepting that the two. cams are geared with relation to each other that they will rnately feed the films. The shutter 50 is so formed and operated that it will close nately close and open the apertures and opeach corresponding aperture atall times excepting during the printing period, and

therefore, the driving means on the two shutters is so geared that they will alter- 70 crate the special feeding means just described. Thereby, the proper relation between the shutter and feed means is established and maintained, whereby the shutter will open the aperture only when there is no feeding movement and close at all other timesx In maintaining and operating films as herein set forth, where the pictures are not in their natural sequence, it is necessary that they be numbered or otherwise indicated so that they can be properly mounted in the projecting machine. For this operation the following mechanism is provided in connection with each of the two feeding frames fill above described. On the angle bar 62 tli'ere'is a finger 80 extending laterally, shown in Figs. 3 and 5, iuposition to engage the push rod 81 that operates through two bars 82 secured on the aperture plate 35. The rods 81 have slots 83 thereon and spiral springs 84 surrounding the rods the feed frame recedes, and (llll'lllfi' the feeding" move-J ment, and therefore while the fingers-are he in moved to another printing position.

The rod 81 has a pin 85 that projects through a slot" 86. of an arm 87 pivoted on a bearing pin 88 in the aperture plate 85. The arm 87 carries a pawl 90 adapted to engage a ratchet wheel 91 on the side of a disk 92 that has numerals 93 steneiled through. As shown here on the upper one of said numboring disks the numbers are l-3-5--7-- 9-11 and on the lower one 2-46-8- 10-l2. At each actuation of the upper dish one of said numbers is brought into registration with a little shutter 94 in the aperture plate 35 just opposite the main aperture plate 37 so that said number will be rinted on the margin of the film. As the fee frame 61 moves upward the arm 87 does not actuate the disk hut leaves it stationary during Y the printing period. Y

This invention is not limited to the particular construction herein set forth, which is presented for the, purpose of explaining the general features of the invention.

The invention claimed is:

1. A machine for printing motion icture films, including an aperture plate aving therein a plurality of apertures for printing a single film, a shaft mounted at right angles to said plate within each aperture means associated withineach shaft for feeding the positive and negative films't ether across the corresponding aperture, a s utter on eachof said shafts, and means for operating said shafts in succession.
