.AI'EARATUS FOR PRINTING AND PRODUCING MOVING PICTURES.

Specification of Letters Patent.

Patented Dec. 16,1919.

Application filed July 17, 1916, Serial No. 109,831. Renewed April 11, 1919. Serial No. 289,409.

following is a full, clear, and exact specification.

This invention relates to a class of ap- "paratus for providing animated pictures of objects.

My invention has for its object primarily to provide an apparatus whereby moving pictures of living objects, scenery and the like maybe printed and produced on an opaque strip, such as paper, or other flexible,

X material of a character ordinarily classed as being non combust1b1e,.1n order to permit various pictures for educational, amusement and other purposes to be produced for eX- hibition in places of instruction and pleasure as well as in homes without endangering the auditors to fire as is incident to the use of the usual very inflammable transparent films, though in instances moving pictures may be printed and produced on transparent films by the use of this process. This is accomplished mainly by providing a process consisting of exposing a sensitized photo,-

graphic .strip to an. opaque photographic negative strip synchronously with operative rays of light being reflected on the negative whereby the pictures on the negative will be produced on the sensitized strip to produce a positive, or by exposing a sensitized photo- 1 graphic strip to a positive at the same time.

reflecting rays of light on the positive whereby the pictures of the positive will be recorded thereon to produce a negative, then subsequently exposing a sensitized photographic strip to the photographic negative:

simultaneously with operative rays of light being reflected on the negative so that the pictures on the negative will be produced on the sensitized stri to produce a positive.

A practical em odiment is represented in i the accompanying drawing forming a part of this specification in which similar charthe descri tion. 1

In the rawings, Figure 1 19a side eleva tion of one form of apparatus embodying my invention.

Fig. 2 is a fragmentary view showing partly in detail a side view of the parts of the apparatus illustrated in Fig. 1.

. Fig. 3 is a sectional View, partly in detail, taken through the apparatus, and

Fig. 4 is a section, partly in detail, taken through one of the reflectors used in the apparatus. a l

The apparatus may be constructed of an outer casing 10 and a removable inner casing 11, both of which may be of any desired size as well as being made of any suitable material: The outer casing v10 is preferably substantially rectangular in shape to provide side walls 12 and 13, a bottom 14;, a

front wall 15, a rear wall, not shown, and a' top 16 which is hinged, at 17, to one of the side walls for opening and closing the upper end of the outer casing, this casing being made so that'light will be prevented from entering thereinto.

lhe inner casing 11 is also preferably substantially rectangular in shape, and this .cas-' ing is .of a height so as to fit closely between the diottom 14 and the top 16 of the outer casing, while the width and length of theinner casing, is smaller than the outer casing, as shown, to provide'spaces'between the sides and fronts of both of the casings. The inner casing is constructed with side walls 18 and 19, a bottom 20, a front wall 21, and a rear wall, not shown, while the top,-

as 22, is hinged, at 23, to one of the side walls to permit the upper end of the casing 29, and through this partition adjacent to its side walls are openings 30' and 31. Entrance is gained into the lower magazine of the inner casing by a door 32 hinged, at 33, to the side wall 18 of the inner casing as well as by a second door 34 which is hinged, at

35, to the side wall 19 of the casing. Through the central part of the side wall 18 of the inner casing is an opening 36 the passage through which is adapted to be side wall 18 between its opening 36 and the transverse partition 28 are two spaced openings 44 and 45, while through the lower art of the side wall 19 between its opening 39 and the transverse partition 28- are also two spaced openings 46 and 47 each of which is in register with each of the openings 44 and 45.

J ournaled in the front and rear walls of the. inner casing 11 are twos'pa- ced shafts 48 and 49 extending through the magazin 25 of the casing, and these shafts are of lengths so that one of the corresponding ends thereof extend beyondthe front wall 21 of the casing. In the front and rear walls of the inner casing11, and projecting through the magazine 29 are two otherspaced shafts 50 and 51 also of lengths so that one of their corresponding ends extend beyond the front wall of the casing. Re-

movably held on the shaft 48 is a delivery reel 52 having wrapped thereon a film, or strip, as 53, of paper, or other opaque material which is ordinarily considered as being non-combustible, and removably held on the shaft 49 is a second delivery reel 54 having wrapped thereon a film or strip, as 55, which may also be of transparent material, or this strip may also be of paper, or other opaque material of a character usually considered as being non-combustible. The opaque strip 53 may be a photographic negative having any desired number of animated pictures of objects or the strip may be an opaque positive with animated pictures of objects thereon.

The strip 55 may be photographically sensitized for printing positive pictures thereon when the strip 53 is a negative, or the strip 55 may be photographically sensi tized for producing a negative when the strip 53 is a positive, as will be hereinafter more fully explained. On'the shaft 50 in the magazine 29 of the inner. casing is re-' movably held a reel 56 for receiving the moving picturestrip 53 from the delivery reel 52, and on the shaft 51 is another removable reel 57 for receiving the moving picture strip 55 from the delivery reel 54.

When the strip 53is threaded through the interior of the machine from the delivery reel 52 to the receiving reel 56 it guidedpast the opening 36 of the side wall 18 of the inner casing 1'1, and. when the 18 interiorly of the inner casing is a framing device, as 58, and on the side wall 19 also on the interior of the casing is another framing device 59. The framing devices 58 and 59 are of similar'formations, and these devices may be of any well known, or preferred types, for example, forms of the devices illustrated, each of which is composed of a front plate 60 with right angularly extending arms 61 and 62 on its upper and lower ends, these arms of one of the front plates projecting from the inner surface of the side wall 18 of the inner casing to space the front plate from this wall before the opening 36, while the arms of the second front plate extend from the inner surface of the side wall 19 of the inner casing so. as to space the front plate from the side wall 19 in front of its opening 39. Through the upper part of the front plate 60 of each of the framing devices is an opening 63, and this opening of one front plate is in register with the. opening 36 of the side wall 18 of the inner casing, while the opening 63 of the other front plate is in register with the opening 39 of the side wall 19 of the inner casing. Through the lower part of the front plate 60 of each of the framing devices is an opening 64,

and this opening of one front plate is in register with'the opening 45 of the side wall bolts, or screws, as 66 and 67, passed through openings in the front plate to allow the second plate to be adjusted toward and from its opposed side wall of. the inner casing, and through each of these adj ustablc second plates is a window 68, both'of the windows being in register wlth each other as well as being in register with the openings 36 and 39 of the side walls of the inner casing and in register with the openings 63 of the front plate 60. The moving picture strip 53 is movably disposed between the adjustable plate 65- of the framing device 58 and the side wall 18 of the inner casing, and the strip 55 is likewise -movably arranged between the adjustable plate 65 of the framing device 59 and theside wall 19' of the inner casing so that by employing the plates in this manner they are adapted to be adjusted for yieldingly holding the Ill strips 53 and 55 during their movements to expose successive parts thereof through the windows 68 and through the openings 63 of the front plates 60 of the frammg devices.

In order to transmit the strips 53 and 55 in unison through the machine from the delivery reels 52 and 54 to the receiving reels 56 and 57, respectively, I provide a mechanism, as 69. The mechanism 69 is constructed of a drive shaft, or stud 70 ournaled in a bearing on the central part of the front wall 21 of the inner casing 11 of the machine, and this shaft is of a length to extend beyond thefront wall 15 of the outer casincr 10 through an opening therein. The shaft 70 may be driven by any suitable power, such as a crank handle 71 provided on the end of the shaft exteriorly of the outer casing of the machine. On the shaft 70 adjacent to the front wall21 of the inner casing is a' drive gear 72, and also on this shaft between the drive gear and the front wall of the outer casing are four sprocket wheels 73, 74, 75, 76. Extending from the front plate 21 of the inner casing on aline inent with the shaft "7 O, and in proximity to the side wall 18 of the inner casing, is journaled a stud 77 with an idler gear 78 held thereon, and this gear is in mesh with the drive gear 7 2; p Also held on the stud 77 are two spaced sprocket wheels 79 and 80. Projecting from the front plate 21 of the inner casing on alinement with the shaft 70, and contiguous to the side wall 19 of the inner casing, is journaled a stud 81 with another idler gear 82 held thereon, and this idler gear is in mesh with the drive gear 72.

- Over the sprocket wheel 73 of the shaft 70 is guided a sprocket chain 83 which passes over a sprocket wheel 84 held on a shaft 85 which is journaled to the upper partof the side wall 19 interiorly of the inner casing, and on the shaft 85 is a sprocket,'or toothed drum 86 adapted to be rotated in the opening 43 of the side wall 19 of the inner casing for engaging the usual aper-' tures, not shown, provided in the strip 55.

. Over the sprocket wheel'74 of the shaft 70 is guided a sprocket chain 87 which passes over a sprocket wheel 88 held on a shaft 89 jou'rnaled in the lower partof the side wall 19 interiorly of the inner casing, and on this shaft adjacent to the sprocket wheel. 88 is another sprocket wheel 90, while on the central part of the shaft 89 is a sprocket, or

toothed drum 91 adapted to be rotated in the opening 46 for engaging the apertures of the strip 55. .Guided over the sprocketwheel 5 of the shaft is a sprocket chain 92 passing also over -a sprocket wheel 93 held on a shaft 94 journaled on the lower part of the sidewall 18 exteriorly of the inner casing, and on the shaft 94 is a sprocket, or toothed drum 95 which is aropening 42 of the side wall 18 of the inner ,7

casing so as to also engage the apertures of the strip 53. On the sprocket wheel 80 of the stud 77 is a sprocket chain 100 which is guided over a sprocket wheel 101 provided on the shaft 48 of the delivery reel 52 exteriorly of the front wall of the inner casing of. the machine, and on the sprocket Wheel 79 of the stud 77 is a sprocket chain 102 passing over a sprocket 103 arranged on the shaft 50 of the receiving reel exteriorly of the inner casing. On the front wall 21 of the inner casing ofthe machine adjacent to its side wall 19 is journaled'a stud 104 having a pinion 105 held thereon, and this pinion is in mesh with the gear 82 on the stud 81. Also on the stud 104 is held a sprocket wheel 106 onwhich is a sprocket chain 107 passing over a sprocket wheel 108 on the shaft 49 of the delivery reel 54 exteriorly of the front wall 21 of the inner casing. stud 89 is a sprocket chain 109 which is guided over a sprocket wheel 110 provided on the shaft 51 of the receiving reel 57 exteriorly Of the inner casing. By properly proportioning the diameters of the drive gear 72, gears, 78, 82, sprocket wheels 73, 74,

, caused to be driven in unison at corresponding speeds for revolving'the toothed drums 84, 88, 94, 97 to transmit the strips 53 and 55 also in unison through the machine.

lVhen the motion picture strip, 53 is threaded through the machine it is guided from the delivery reel 52 through the opening 20 of the transverse partition 24 of the inner casing 11, and the strip is moved into engagement .with the toothed drum 99 to which it is held in movable contact by C0111- pression rollers, as 111, of well known forms arranged on the side wall 18 interiorly of the inner casing. The strip is then passed through an opening 112 in the top wall 113 of a casing, or box, as 114, which extends interiorly of the inner casing of the machine before the registered windows 63 and '68 of the framingxlevice 58, the boxbeing formed with a bottom wall 115 having an opening Over the sprocket wheel 90 of the I 116 and afront wall 117 with an opening 118 therethrough which is in, register with the windows 63 and 68 of the framing device 58;

A loop, as 119, is formed in the strip 53 at 5 "the opening 112 of the box 114, and the strip is guided betweenthe side wall 18 of the inner casin lland the adjustableplate 65 of the framing device 58 for being transmitted before the windows 63 and 68 of this framing device as well as before the opening 118 of the front wall 117 of the box 114. From the framing device 58 the strip 53 is passed through the opening 116 of the bottom wall i of the box 114, and after a second loop- 120 is formed in the strip it is guided into engagement with the sprocket drum 95, the strip being held in movable contact with this sprocket drum by compression rollers, as 121, provided on the side wall 18 of the inner cas- 20 ing of the machine. The strip is then passed through the opening 30'of the transverse partition 28'of the inner casing 21 for being wrapped on the receiving reel 56 during the transmission of the stripthrough the ma- 25 chine.

When the motion picture strip 55 is threaded' through the machine it is guided fromthe' delivery reel 54 through the opening 27 of the transverse partition 24 of the inner cas- 30 ing 11, and the strip is moved into engagement with the toothed drum 86 to which it is held in movable contact by compression rollers, as 122, of well known types provided on the sidewall 19 of the inner casing. A loop,-

as 123, is then formed in the strip 55 after which the strip is arranged between the side wall. 19 of the inner casing and the adjustable plate 65 of the framing device 59. A.

second loop, as 124, is then formed in the strip which is guided into engagement with the sprocket drum 91, and the strip is held in movable contact with this sproc et drum ranged on-the exterior of the side wall 19 of the inner casing. From the sprocket drum ti) through the machine.

In order. to cause the strips 53 and 55 to be intermittently checked during the trans mission through the machine, on the exterior of the wall 18 of the inner casing 11 55 of the machine is journaled a shaft 126 one endof which extends beyond the front wall 21 of the inner casing, and on this extending end of the shaft is a pinion 127 which is in mesh with the gear 78 of the stud 77. Also on the shaft 126 is a drum 128 disposed in the opening 45 of the side wall 18 of the inner casing, and extending from diametrically opposite parts'of this drumare SBtSiOf spaced teeth, as 129 and 130, ,adapted to en- N gage the apertures of the moving picture by a pair of compression rollers, as 125, ar-

strip, the strip being held in movable contact with the toothed drum by a block, as 131, which is yieldingly forced inwardly of the opening 64 of the front plate 60 of the framing device 58 so as to abut against the strip to hold it in engagement with the toothed drum by a spring, as 132, arranged on the front plate of this framing device. 011 the-exterior of the side wall 19 of the inner casing of the machine is journaled a shaft 133 one end of which extends beyond the front wall 21 of the inner casing, and on this end'of t'he shaft is a pinion 134 meshing with the pinion 105 of the stud 104. On the shaft 133 and disposed in the opening 47 of the side wall 19 of the casing is a drum 135 jecting from diametrically opposite parts thereof, and which engage the apertures of the moving picture strip 55, this strip being held in movable contact with the toothed drum by a block, as 138, yieldingly forced inwardly of the opening 64 of the front plate 60 of the framing device 59 so as to contact with the strip to hold it in engagement with the toothed drum 135 by means of a spring,

, havingspaced sets of teeth 136 and 137 pro as 139, providedon the front plate of the,

framing device 59. The pinions 127 and 134 are proportioned so that when the other parts of the mechanism 69 are operated, as above mentioned, the shafts 126 and 133 will be driven at speeds corresponding to the other shafts and studs of the mechanism, and the drums 128 and 135 are also proportioned together with the sets of teeth of each drum being relatively spaced apart that the movement of the strips 53 and 54 when transmitted through the machine will be in-:

termittentlyv checked synchronously so that corresponding successive portions of both strips will be exposed in unison to each other through the 'registered windows and openings 63 and 68 of the framing devices 58 and 59 aswell as through the opening 118 of the box 114 interiorly of the inner casing.

While specific forms of the intermittent checking devices are shown and descrlbed,

instead thereof I may employ any other wellknown, or preferred types of devices for causing the strips to be intermittently checked the machine. On the front wall 117 0 box 114 interiorly of the inner casing of the machine is a lens barrel 140 with one or more lenses, as141, mounted therein, and this bar'- during their transmission throngl f t e rel isarranged so that the focus of the lens will be in the ath' of the successive parts of the moving picture strips exposed through the registered windows and open1ngs-63 and '68 of the framing devices 58 and59 aswell as through the opening 118 of the box 114.

Interiorly of the lens box 114 of the inner casing arearranged one, ora plurality of lamps, as 142 and 143, which are referably electrically lightedfrom any su ta le source of supply, for example from a battery, as

144, from one terminal of which is a wire 145 leading to one pole of one of the lamps, and the corresponding second poles of the lamps are connected by a wire 146. From the second terminal of the battery 144 is a wire 147 leading to a switch 148 adapted to be swung into engagement with a contact 149 of a wire 150 leading to the other pole of the second electric lamp so that by swinging the switch 148 into engagement with the contact 149 the lamps will be lighted by the circuit being closed, the current passing from the battery overthe wire 145 to one of the lamps, through which the current will pass over the wire 146, and also from the battery the current will pass over the wire 147, through the switch 148, and over the wire 150 to and through the second electric lamp, the light from these lamps being extinguished by disconnecting the switch 148 from the contact 149. Each of the lamps 142 and 143 is mounted in a reflector, as 151, which may be parabolic, or pear-shaped, as shown, in the form of a mirror, or the reflector'maybe of metal having an interior refleeting surface for deflecting the rays of light from its lamp through the opening, as 152, of the reflector. One of the reflectors is arranged in the upper part of the box 114, while the other reflector is mounted in the lower part of the box, and these reflectors are disposed in converging arrangement so that the rays of the lamps will be deflected on the portions of the strip 53 exposed through the registered windows 63 and 68 of the framing device 58. The exposures of the strip 53 to the lens 141 will. thereby be effected by the reflected rays of light from these lamps.

,To cut-ofl' at intervals the light deflected on the exposures of the strip 53 when transmitted through the machine, a shutter, as 153, of any desired form may be provided. The shutter 153 is disposed interiorly of the inner casing for being revolved across the plane ofv the focus of the lens 141, and this gear 155 in mesh with a bevel'gear 156 on the upper part of a vertically disposed shaft 157 which is ournaled in bearings on the exterior, of the side wall 18 of the inner casing. On the lower end of the shaft 157 is another bevel gear 158 meshing with a bevel gear 159 provided on the shaft 126 of the toothed drum, orintermittent operating device 128,

= and these bevel gears of the shutter are proportioned so as to be operated when the shaft 126 is driven for cutting-01f the light on the strip 53 at proper intervals-as is in- CldGIltWltll customary methods for shuttingoff the light in operating the usual moving picture machines.

In order to print the moving pictures of a photographic opaque negative strip on a sensitized opaque photographic strip, or ona sensitized transparent photographic strip to produce a positive the negative is wrapped on the delivery reel 52, and the sensitized strip is threaded in the machine, as above explained, for transmission to the receiving reel 56 so that successive portions of the negative strip will be exposed through the through the windows 63 and 68 of the fram- I ing device 58 to the sensitized positive. Simultaneously with the focusingof the pictures of the negative the light from the lamps 142 and 143 is deflected by the reflectors 151 on the exposures of the negative strip 53, and the pictures will thereby be printed on the sensitized strip 54 to produce a positive when the machine 15 operated.

To produce a photographic opaque negative, or a photographic transparent negative of the pictures of an opaque positive strip, the positive stri is wrapped on the delivery reel 52, and tile positive is arranged in the machine, as hereinbefore explained, for transmission to the receiving reel- 56 so that successive portions of the positive will be exposed through the windows 63 and 68 of the framing device 58 to the lens. A sensitized photographic strip for producing a negative is wrapped on the deliv reel 54, and the strip 55 is threaded throug the machine, as described, so as to be transmitted to the receiving reel 57. When the machine is operated the successive pictures of the positive exposed to the lens 141 will by employin thelight of the lamps, as above describe be focused on the sensitized strip, 55 for recording the pictures thereon which are afterward converted to a photographic negative in the usual manner.

To print the pictures of this photographic negative when the strip is opaque on a sensitized opaque strip, or on a transparent photographic sensitized strip, to produce a positive, the negative strip 53 is wrapped on the delivery reel 52, and the strip is threaded'in the machine, as explained, for transmission to the receiving reel 56 so that consecutive i portions of the negative will be exposed through the windows 63 and'68 of the framing devibe 58. The sensitized strip 55 is lens 141 on the successive exposures of the,

- sensitized strip to produce a positive of the pictures when the strip is developed in the customary manner. By this process moving pictures may be readily printed from an opaque negative strip on an opaque; or transparent sensitized strip to produce positive pictures of the negatlve, or moving pictures may be reproduced from an opaque positive strip to an opaque, or transparent sensitized strip to produce a negative and then printed on a sensitized strip to produce a positive. Moreover, by employing a suitable lens the pictures may be enlarged or reduced in sizes, as occasion requires To operate the machine following the proper arrangement of the moving picture strip in the-machine, the crank handle 71 is turned for revolving the shaft 70, and the drive gear 72 with the sprocket wheels 7 3, 74, 75, 76 will be revolved. The gears 78 and 82 will then be rotated in opposite directions. The rotation of the gear 78 will drive the sprocket chains 92, 96, 100, 102 for driving the' shafts 94, 98, 126, 48, to rotate the sprocket wheels 93,.97, 101, 103 with the pinion 127, drum 128, and toothed drums 95 and 99 to intermittently transmit the strip 53 from the delivery reel 52 to the receiving reel 56, the shutter 153 being operated in unison with these parts, as hereinbefore explained. Simultaneously with the rotation of the sprocket wheels 73, 74, 75, '76 the sprocket chains 83 and 87 will be driven to rotate the sprocket wheel 84, shaft 85, toothed drum 86, sprocket wheels 88, 90, shaft 89, toothed drum 91, sprocket chain 109, sprocket wheel 110 and shaft 51 of the receiving reel 57, and with the rotation of the gear 82, the pinion 105, sprocket wheel 106, shaft 104, pinion 134, shaft 133, drum 135, sprocket chain 107, sprocket wheel 108, and theshaft 49 will be operated to intermittently transmit the strip 55 from the delivery reel, 54 to the receiving reel 57. By previously closing the electric circuitto the lamps 142 and 143, as above explained, the light from the lamps will.be deflected by the reflectors on the strip 53 during the operation of the machine, while a specific for operating said gearing.
