photographed. Another object is to provide.

16 a suitable illuminating systemand a means for preventing the heat of the illuminating system from damaging the object being photographed. Another object is to utilize the ventilating system for moving and for hold- 30 ing the card in position for photographing. Another object is to provide an automatic metering device upon which the number of ex sures or footage of film used for one tit e may be readily ascertained. Still 35 another object is to provide a measuring device which will at all times render visible to the operator the amount of film as it is used photographing a card or title, and other objects will appear from the following s ci- 30 fication, the novel features being particu arly pointed out in the claims at the end thereof.

Coming now to the drawings wherein like reference characters denote like parts throughout:

Fig. 1 is a top plan view partially in section showing a preferred embodiment of a motion picture title making machine constructed in accordance with and embodying one form of my invention;

Fig. 2 is a fragmentary side elevation of the machine shown in Fig. 1;

Fig. 3 is a fragmentary front elevation of the same machine;

Fig. 4 is a fragmentary detall of the meter mechanism removed from the camera together with a frame which surrounds the exposture opening 5 Fig. 5 1s a section on line 55 of Fig. 4 taken through the meter mechanism and a part of the plate which supports it; and

Fig. 6 is' a wiring diagram for the photogra hing machine.

is machine may consist of a motion picture camera 1 which is driven at a suitable speed bg a motor 2 through a belt 3 and pulley 4. he mechanism of the camera forms no part of the present invention, and is not, therefore, shown. It may, however, be of the type shown in Patent No. 1,572,252, Tessier, Feb. 9, 1926, or of the type shown in Patent No. 1,588,082, Wittel, June 8, 19 26.

The pulley 4 actuates a shaft 5 which-is connected to suitable parts of the camera mechanism to which there is also connected a shaft 6 which carries a bevelled gear 7 and a handle 8 by which the parts may be manually opirated if desired. Thus the machine may operated either manually by the handle 8 when the belt is disconnected or it may be operated by the motor 2 from a convenient source of power for which a switch 9 is provided, as shown in Fig. 3.

I prefer to rovide artificial illumination since this may more readily kept constant. To this end there is a. substantially air tight chamber 10 which has curved side walls 11 which serve as reflectors for the lamps 12 which are preferably of the concentrated filament type. Bathe plates 13 mask-off the light from lamps 12 so that no' light rays may passdirectly into the objective carried by the lens barrel 14 which projects through an aperture 15 in the rear wall 16 of the casing. The forward end 17 of the bafiie plates are preferably spaced apart just a sufiicient distance to permit the objective to form an image of an object to be photographed at 18 upon the film F in the camera 1.

In the forward part of the casing there is a panel 19 which is provided with an exposure opening 20. This panel carries an exposure frame 21 which is provided with an opening 22 which is proportionate in size to one exposure frame of a motion picture film. A Frame 21 is provided with apertures 2 through which screws 24 pass, these screws also passing through washer 25. This permits an initial adjustment of frame 21 so that the center of the exposure aperture 22 may be properly aligned up with the axis of the objective 26 carried by lens barrel 14.

Motion picture titles are ordinarily printed upon cards. For use with this machine the cards are of a standard size, and are accurately positioned for exposure by means of the bevelled strips 27 and 28. As best shown in Fig. 8, strip 27 is bevelled toward the exposure opening 22 and strip 28 is bevelled at 30 away from this opening. Thus the strip 28 carries a downwardly extending ledge against which the bottom of the card may be placed. By turning the card upon its bottom edge the card may be rotated into position. The edges of the card, which may be designated broadly as C2, contact with and are positioned by the bevelled edges 29 of the strip 27. v

In order to hold the cards in position for exposure I provide an air moving mechanism shown diagrammatically in Fig. 2 as a power fan 31 suitably mounted in a pipe 32 leading from the top 33 of the chamber 10. This fan is constantly running and creates a suction tendin to hold a card in position for exposure. he casing is not completely air tight except for the exposure opening, as there is some air leakage about the objective and past the finger opening 34 which facilitates removing the card C from exposure position.

As will be readily seen the air passes from pipe 32 more rapidly when there is no card in position for exposure so that the heat from the lamps 12 is drawn from the casing 10.

The double function resulting from the arrangement above described is particularly useful because it not only ventilates the lamp house 10 but, by holding the cards in position, makes very rapid operation of the machine possible. The operator may position a card behind a card being photographed by locating the bottom on the bevel 30 of strip 28 with the top edge of the card in the position shown in the fine broken lines G in Fig. 1. By drawing the first card upwardly from the exposure position C and by releasing the second card, the latter is rapidly drawn in the direction indicated by the arrow to the exposure position indicated at C. The bevelled edges 29 automatically position the card as it turns about its contact with strip 28, and the suction causes the card to move rapidly.

In changing cards the operator grasps the top through the finger opening 34 and pulls the card from the exposure frame merely dropping a second card in place very much as small size printing presses are operated.

The number of exposure frames in a motion picture film title are determined by the amount of wording or reading on the title, and it is, therefore, necessary for the operator to know how many frames are being exposed by the camera. In order to determine this mechanism as indicated in Fig. 3 gives visible record upon scale 39 by means of a pointer 40. This scale may he graduated into suitable units and is here shown as being graduated into units of feet. The title cards may conveniently bear on the back the number of feet required.

There is a shaft 41 having a bevelled gear 42 meshing with a smaller gear 7. As best shown in Figs. 1 and 2 shaft 41 passes through the wall 16 of the chamber 10 across the chamber towards the panel 19. Referring to Fig. 4 the forward end of shaft 41 is supported in a bracket 42 which may be carried by panel 19. A beveled gear 43 drives a similar gear 44 so thatshaft 45 which is supported in bearings 46 is continuously rotated as long as the camera mechanism is rotated either by motor 2 or handle 8. Shaft 45 carries a thread 47 and this thread may drive the pointer 40 across the scale 39 in the following manner:

The pointer 40 is carried on the end of a lever 48 supported on a fixed shaft 49 at one end and a movable shaft 50 at the other. Shaft 49 is fixedly supported in brackets 46 which also support shaft 45. Shaft 50, however, may move relative to bracket 46 being guided in the arcuate slots 51 in the ends of the brackets, as best shown in Fig. 5. On the upper edge of lever 48 there is a threaded segment 52 adapted to mesh with a screw 47 when member 48 is moved through arms 53 by means of hell crank levers 54 pivoted upon a shaft 55 supported by brackets 56. The long ends 57 of these bell crank levers are bent downwardly at 58 and extend through slots 59 in the exposure frame 22, the ends being bent over at 60 to form card contacts.

The parts above described are balanced so that very little pressure is required to thrust member 58 inwardly from the full line position to that diagrammatically indicated in dot and dash lines, Fig. 5. Consequently when a card C is drawn inwardly by air pressure the bell crank lever is swung, thus operating member 48 throwing the gear segment 52 into mesh with the rotating screw 47. This in effect forms a clutch which drives the pointer carrying member by means of the screw as long as a cardis in position to be photographed. As soon as the desired number of pictures have been made, as indicated by the pointer moving across the scale 39. the card C is withdrawn permitting the bell crank lever to move a sufficient distance for the teeth of. the screw 47 and the segment 52 to become unclutched or disengaged; at which time a spring 61 which is attached at one end 62 to member 48, and at the other end 63 to the panel'19 to draw member 48 upon its supporting rods 49 and back to the zero position on scale 39. Thus it will be seen that the film footage for each title may be watched during the printing operation.

I preferably make the motion picture camera 1 large in size so that a lar e roll of motion picture film can be carrie However, in order to indicate the total film footage I provide a dial on the outside panel 19, this dial havin a hand 71 which may indicate on a scale 72 the total amount of film which has been exposed in the camera.

In order to drive the hand 71 I provide on the end of shaft 45a worm 7 3 meshing with another gear 74 which drives a shaft 75.

Shaft 75 may beconnected throughsuitable reduction gearing with a shaft 76 which drives the dial hand 71.

The meter mechanism may be oiled from an oil tank 80 by means of suitable pipes 81 leading to the parts which need lubrication.

I also prefer to provide a volt meter 82 and a rheostat 83 so that the brilliance of lamps 12 may be properly maintained. This is shown diagrammatically in Fig. 6.

The operation of the photographing machine above described is as follows: Switch 9- is operated to start the motor and light the lamps 12. The operator has a pile of cards bearing the titles to be made,'each card preferably also bears a mark indicating the footage required. These cards are successively fed into printing position, and are there held by air pressure until the ointer 40 indicates the desired footage. As t e camera is continuously driven the developed film will bear a series of titles with a few film areas separating each series which bear no titles. This is convenient for editing purposes as the separate sections are cut apart through these areas. \Vhen the dial 70 indicates that the camera film has become exhausted the machine may be stopped and the camera reloaded in the usual manner.

It is obvious from the foregoing description that certain features of my invention are useful for other purposes besides making motion picture titles, and I do not wish to be limited except as indicated by the appended claims.
