AUTOMATIC PHOTOGRAPHIC CAMERA.

.SPECIFICATION" forming part of Letters Patent No. 544,669, dated August 20, 1895.

Application filed November 1, 1894. Serial No.52'7,669- (No model.)

To all whont it may concern- Be it known that I, EUGENE J. GREGORY, a citizen of the United States, residing in Sacramento, county of Sacramento, State of California, have invented an Improvement in Automatic Photographing-Oameras; and I hereby declare the following to be a full, clear, and exact description of the same.

Hy invention relates to an apparatus which is designed to take and finish photographs instantaneously and automatically. It especially designed for the purpose of placing identifying photographs directly upon railway-tickets, letters-of-credit, and other papers in which it is desirable or necessary to have the user of the tickets or papers identified. It may also be used for secret service, newspaper and other Work and for photographing views, buildings, the. It may also be employed in conjunction with any well-known coinactuated mechanism whereby a picture may be taken and delivered directly to the party desiring it without other manipulation than can be effected by the apparatus itself.

It consists in certain details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is an exterior view of the apparatus. Fig. 2 is a view of the carrier and slide. Fig. 3 is an end elevation with the outer casing removed. Fig. at is a side elevation. Fig. 5 is a view of the fixing-bath. Fig. 6 isa view of the gearing, taken from the sideopposite to Fig. 4. Fig. 7 is a plan view of the gearing. Fig. 8 is a view of the mutilated gears separated from each other.

The object of my invention is to provide a paper ticket or card, one portion of which is adapted to receive printed, written, or other matter, and another portion of which is sensitized, so as to be capable of receiving a direct positive photographic picture, and a mechanism by which the operation of taking, developing, fixing, washing, and preparing the picture for delivery is automatically conducted.

In carrying out my invention I employ a closed case A, of any suitable or desired form, having at any convenient point a slotted opening B, which allows of the introduction of a carrier 0' into a holder 0, and this holder is adapted to travel between vertical guides D, situated within the case.

The ticket,card, or other paper upon which the photograph is to be produced is specially prepared, one portion being adapted to receive Written or printed matter of any description and the other end being properly prepared or sensitized to admit of a picture being taken and finished directly upon it, not as a negative, but as a positive finished picture.

In thepresent case I have shown the device as adapted to contain a ticket similar to a railroad-ticket and having a sliding plate G which travels in grooves and is movable longitudinally in the carrier C. This slide-plate normally remains at the bottom of the carrier C and covers the sensitized portion'of the paper'upon which the picture is to be taken while in its normal condition. These carriers may be cheaply made, and each one put up with its inclosed ticket all ready for use and so constructed that they may be thrown away after the picture has been properly finished and removed from the apparatus, or they may bemade of permanent materials, so that each ticket can be slipped into a holderin readiness for use.

The ticketis introduced through the slotted opening B and the edges of the opening are protected byany flexible fabric which will yield sufficiently to allowthe holder or carrier to pass, but will close against its edges and sides so that the interior of the apparatus willl remain light-tight. When the earrieris introduced into the holder 0 and pushed down, the upper edge of the slide 0 being properly constructed for that purpose, engages the top of the holder and is arrested,so that the carrier C moves down far enough to expose the lower sensitized portion of th card within the case or camera.

By the movements of the machinery, to be hereinafter described, the holder is first retained so as to bring the sensitized surface into line with a lens D, which is properly fixed within the outer casing and focused, so that the person or object presented in front of it will be photographed upon the face of the card when the shutter is moved and the exposure made.

ICC

In order to provide a light which will be sufficient for the purpose of taking the pictu re, any of the usual or Well known flash-light powders may be employed.

1 have shown a holder E fixed to the exterior of the case adapted to contain the necessary amount of powder, and an igniting device by which it is burned at the instant when the shutter is opened. Various devices may be employed for this purpose. In the present case I have shownahammer F adapted to strike upon a cap so as to explodeit and ignite the powder. This hammer is actuated by a spring G and is held raised above the cap by means of a trigger H. This trigger is actuated simultaneously with the movement of the shutter by means of a lever-arm I which projects through the side of the case, so that its outer end acts to disengage the trigger when moved. The inner end of the arm I is fixed to asliding-bar J which extends out through the side of thecase, so that its outer end may be seized by the operator and pulled outward. The inner end connects through appropriate lever mechanism, a desirable form of which is shown at J with the shutter K, so that when the slide is pulled outwardly it opens the shutter and simultaneously pulls the trigger, allowing the hammer to fall and ignite the powder, so as to produce a su fficient light upon the object to be photographed. The shutter being opened and the sensitized portion of the card brought into line with the axis of the lens, the picture will be taken upon the surface. The shutter is then closed, as by the return of the slide or by a spring 20 so that the proper amount of exposure is had and the light immediately cutoff. The slide carrying the card is at the same instant released at the completion of the pull upon the slide J by the action of an inclined or camshaped lugj fixed upon the inner end of the slide J and adapted to engage a lever M. This lever acts upon a bell-crank lever N, which carries a stop 0, and this stop engages a lug 0 upon the sliding holder 0, so as to retain it at first in the position to receive the carrier while the latter is being introduced. Then the slide-rod J is pulled out it operates the flash-light, and as the shutterinstantly closes, the completion of the movement of the rod J causes the oamj to engage the lever M and through its connections to release the holder 0 and allow it to drop to the second position, where it is in readiness to be operated upon by the developing-bath. It is arrested in this position by a suitable stop Q, operated as will be hereinafter described.

The developing-bath R consists of an approximately rectangular tank closed on the sides, ends, and bottom, and open upon one edge, which, when it is in proper position, becomes the top. This open end is made divergent, as shown, so that the developing-bath may be moved up and inclose that portion of thecard having the picture upon it without touching the card. This movement is pro duced by means of a shaft S, moved by mech anism to be hereinafter described, and an arm S connecting the shaft with the developingbath R. The card being in the position last described, the mechanism acts to rotate the bath R from a position in which it is withdrawn from the line of travel of the card-carrier to a vertical position, in which it incloses the lower part of the card. When it reaches this position, it becomes stationary by the operation of the mechanism, and is then filled with the developing-liquid from a pipe T, which leads from a tank U in the upper part of the casing to such a point that when it is open it will discharge liquid into the devel oping-bath until the latter is su [liciently filled. The pipe T is controlled by a valve V, and this valve is opened by means of a lever W, operated from the aforesaid mechanism, and is allowed to close when the bath sufficiently filled. The bath remains in this position with the photographic impression immersed in the developing-liquid for a sut'licient time to properly develop the picture. As soon as the proper time has elapsed the mechanism, continuing to act, will withdraw the bath, rotating it about its carrying-shaft S, and as it returns to its normal position the contents will flow out through an angularly-formed spout R projecting from one corner of the bath in such a manner that the liquid will flow from it into a receivingdank a situated in the lower part of the casing, from which it may be discharged. While this bath is moving backward to its normal position a second bath 1), constructed in a similar manner and carried by a rotary shaft b, is gradually brought into a vertical position, where it incloses the photographic picture. This bath is filled at the proper time from a tank U by the opening of a valve operated by a lever W from the driving mechanism, the liquid llowing from it through a pipe T, which discharges into this bath and fills it in the same manner that the bath R was tilled. This bath contains the fixing solution, and as soon as it has performed its offiee it is again retracted by the action of the driving mechanism and the liquid contained by it is poured out of a corner spout in the same manner that the bath R was emptied, the contents .talling into the same receiving-tank and being conveyed away. As this bath 1) returns to its normal position, the shaft 1) which carries it acts through a lever-arm o and an intervening latch d to tilt the lever-stop Q and again release the sliding carrier 0, which now allows the end of the card with the picture upon it to be plunged into a washing-tank e, situated between the guides and at the bottom of the case. \Vithin this bath the picture is properly washed, and after the washing is completed the slide and carrier are raised to the top of the casing by means of a cordf passing over a pulley g, and thence leading over proper direction-pulleys to a drum it, upon. which it is coiled for the purpose. hen the sliding ICC holder has thus been raised to its highest position, it is again allowed to rest upon the stop 0, and the sliding carrier 0' is withdrawn and the picture may be passed between rubbers or surfaces which will assist to dry it. The rapid drying of the picture may also be as sisted by the use of alcohol into which it may have been passed, either while being Washed or afterward, so that the rapid evaporation of the alcohol will assist in drying the card and making it ready to be delivered. The card is then in readiness to be removed from its carrier, and if anything is to be written upon the opposite end it is completed in the proper manner and ready to be delivered to the one for whom it is intended.

The movement of the various portions of the apparatus at the proper time may be effected in many difierent ways which will be obvious to a mechanic, and I do not wish to confine myself to any special mechanism for producing these various movements. In the present case I have shown a train of gearing actuated by aspring 1 coiled within and operating a barrel j. Upon the shaft of this barrel is'a gear-wheel 7a, which acts through a suitable train of gearing to drive a fan Z, which acts as a regulator for the speed of the machinery. Upon the same shaft are fixed the mutilated gear-wheels m m m lated gear-wheel m engages the pinion n,which is fixed upon the shaft S, by which the bath R is actuated, and turning this pinion it rotates the shaft to bring the bath into the vertical position required for developing the picture.

The shaft b, which carries the fixing-bath I), also has a corresponding pinion b upon it, and by means of anintermediate gear-wheel w the two are actuated simultaneously, so that as the developing-bath is brought into vertical position to submerge the picture, the fixing-bath is correspondingly moved out of the way. The mutilated gear m passes out of engagement with this pinion n, and the gearing b and the intermediate gear X remains stationary during a period which itis de-:

sired to submerge the picture in the developing-bath. then this period has elapsed the gear m engages a pinion p, and this, acting upon a pinion 0 on the same shaft with the pinion n, reverses the direction of rotation of these shafts and thus retracts the developingbath and rotates the fixing-bath into a, posi-' tion to submerge the picture within it. The set of teeth upon the mutilated gear m again engaging the pinion n rotates these connected gears X and b and again returns the baths It and b to their normal position upon each side of the vertically-moving carrier. During this last operation of the movement, the carrier being released, as previously described, has dropped the picture into the washingbath, and after the washing is completed the mutilated gear m engages the teeth of a wheel q, and this, acting upon the pinion r of the winding-drum h, actuates the latter and raises the carrier to its position in the upper part The mutiof the case. There being but few teeth in the mutilated gear on they soon pass out of engagement with the gear which they actuate, and thus allow these parts to again come to a state of rest.

The valves by which the developing and fixing solutions are respectively discharged into their baths when the latter are in the proper position are actuated by a cam-lever s, which, during the rotation of the wheel 0', alternately engage the levers by which the valves are opened, and are disengaged in time to allow the valves to close when the baths have become filled.

The parts are brought to a state of rest after each revolution of the barrel j by a stop P, which engages a lug 1" upon the bar J. In order that the developing chemicals may be separated from each other to prevent too rapid decomposition I may use a third tank U, in which event the said tank will be provided with a suitable valve actuated simultaneously with the valve V, whereby the chemicals of the tanks U and U will be discharged in proper proportions into the tube Tand thence into bath R.

Having thus described my invention, what I claim as new, and desire to secure by Letters I Patent, is-

which the sensitized card or ticket isinclosed,

a case within which the apparatus isinclosed, a slotted opening for the introduction of the carrier having flexible light tight flaps which normally close the opening, but which yield so that the carrier may be introduced into the slide while the flexible flaps prevent the entrance of light.
