BEBTELL W. KING, OF BROOKLYN, NEW YORK.

HEARS FOR INSCBI'BING UNEXPOSED PHOTOGBAPHIC FILMS, PLATES, OR THE LIKE.

Application filed larch 11, 1915.

T all whom it may concern:

Be it known that I, BERTELL W. KING, a .itizen of the United States, residing in Brooklyn, county of Kings, State of New York, have made a certain new and useful. Invention in Means for Inscribing Unexposed Photographic Films, Plates, or the like, of which the following is a specification.

This invention relates to means for supplying inscriptions to unexposed photographic films, plates or the like.

The object of the invention is to provide a device which will permit writing or printing on or otherwise marking or inscribing an unexposed film or plate as used in photo' raphy, which is simple in construction, e cient in operation and cheap to manufacture.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location, and relative arrangement of parts all as will be more fully hereinafter set forth, as shown on the accompanying drawing, and finally pointed out in the appended claims.

Referring to the drawing,--

Figure l is a plan view showing the back or bottom of a film camera embodying my invcntion.

Fig. 2 is a sectional view taken on the line 2-2, Fig. l, and looking in the direction of the arrows.

Fig. 3 is an enlarged detail broken view of a portion of the construction embodying my invention.

' Fig. dis a view taken on the line 4-4, Fig. 3, and looking in the direction of the arrows.

Fig. 5 is a diagrammatic view showing a circuit arrangement employed in connection with my invention.

Fig. 6 is a plan view of the electric light bulb and attachment as employed in connection with my invention.

The same part is designated by the same reference numeral wherever it occurs throughout the several views.

In photography it is often desirable to print, mark, or otherwise inscribe on the )late or film employed before or after a picture is taken, the name of the place photographed, the date, the autograph of the person photographed, or other distinguishing or designating inscriptions. In the use of plate cameras, the method heretofore Specification of Letters Patent.

Patented Sept. 7, 1920.

Serial No. 13,582.

employed consists of marking in chalk or pencil upon the plate holder, the desired inscription. It is evident that such inscriptions so made, do not appear upon the photoplate when developed, nor upon the photoprint made from the developed plate. In order that such inscription shall appear upon the plate when developed, or the print made therefrom, it is necessary to scratch the desired inscription upon the plate or else write or print the same on each individual rint. These methods are all objectionable. Vhere the holder itself is marked there is the danger of the marks becoming obliterated, or remaining thereon when another picture is taken, thereby causing confusion. Where the desired inscription is scratched upon the plate this can be done only after the plate is developed and not at the time the exposure is made. This incurs the danger of the operator forgetting the desired inscription during the time or period intervening the exposure and development. here each individual print is separately inscribed, it involves tedious labor and increased expense and separate handling of each individual print. Further, when photographic films are employed in long reels or rolls, as in motion photography, it is necessary to mark on a roll of film that has been exposed and used in taking pictures of a particular scene or locality, the number of the scene, or the name of the place photographed, or any other notation employed by the various motion picture producing operators, to distinguish one reel from the ther. It has been the practice heretofore, at the completion of a run of scene, for the operator to open the camera, and make the desired notation on a film, and to then close the camera in preparation for the next run of film. In this practice, not only the particular film upon which the notation is made is wasted, but also from two to three feet of film is exposed and destroyed by the resulting exposure thereof to light when the allow from six to twelve or more individual eiiposures or pictures, it is often desirable to write or print on ach individual film portion which forms a part of the individual exposure, the desired inscription. it is also desirable to write or print the oesircd inscription upon the unexposed film so that such writing will be reproduced upon each print made from the negative.

this, such as providing the camera casing with a slot opening upon a portion of-the film reel, so that sharp pointed steel pencil or punch may scratch through the light excluding wrapper over the film, which wrapper is exposed through the slot referred to, and thus, by allowing the daylight to pass through the portion of the wrapper so scratched, expose the film in accordance with the scratching.

The disadvantages of this method are ob vious. The steel pencil point-may become dull, and not make a clean cut through the wrapp r, or the pencil point might be pressed with too great a force through the wrapper and cut through the lil': itself thereby injuring and weakening it. li urther a loose, individual member, namely the pencil, must be provided, and being-r independent of the ca .iera, is apt to be lost, or misplaced. The greatest disadvantage enred, however, is that, due to the cutaction necessary, it is practically impossible to is individual and upon the film, without tearing tie wrapper, and exposing and spoilin the film.

It is among the special urposes of my invention to provide a unitary arran ement permanently attached to a cam ra wherein possible to transmit writing of any th film orjplate ciaracteristic handwriting,

lesircd characterislic to negative before it is exposes, without e:: posing any portion of the plate BL111 OT light eXch. as wrapper to the ivl. 'h" and withoi injuring" the film or the wrapby cutting or piercing action.

in j out the objects of my invention 1 pro se to employ the usual camera, which in t J instance is shown for illustrative purposes to be a well known collapsiblecamera or k dak film camera com prising a frame or casing in which is mounted at ends the usual film rollers 8, 10, y .l provided with the usual hole or openi 9 for deermining how far the film must he turned by the roller which is wind: up, after an exposure has been made, to place new and unexposed surface behind the camer known manner.

In the/form shown, the roller 8 has wounl around it the new or ruieitposed film, the film 11 passes therefrom and extends through a suitable slot or 2, to the roller passage as shown. in

Various ways have been suggested for accomplishing a lens, in the usual. and well 1 tached to, or forming a part of the shaft 13 are arms or rigid limbs 15, 16. Suitably keyed to the shaft 14;, and held thereon by means of nuts 17 are links or arms 18 and 19. lhe links or arms 18, 15, and 16, 19, are secured together by rivets or the like 20 which also serve to secure thereto, similain links or arms, forming well known form of lazy tongs or pantogranh, the upper lazy tones member 15 18 actine' outside of the y C: 5 7 Fr casing 7, and the lower lazy tongs member acting inside of the camera through a slot 22 formed forthat purpose in the interior of the wooden camera frame or casing 7. It will be readily seen, that due to the arrangement of the shafts 18, 14:, and their respective lazy tongs attachments, any movement in direction at the extremity 23 of the outside lazy tongs will. be transmitted identically reproduced the extremity of the lower or inside lazy tongs arrangement 16, 19.

The extremity 30 of the upper lazy tongs consists of'a point of steel or other conduct. ing material such as lead or the like, and is proyiced with a knob or handle 25 to facilitate the writing movements of the lazy tongs.

The extremity 2 1 of the lower lazy tongs carries a small electric light bulb 26. This bulb is coated over with layer of any suitable light excluding material such black paint except for a small pin point portion 27 which is so positioned as to be the nearest point of the bulb to the film 11. The tubular shaft 13 and the sha t 1 1 are of such len th that the bulb 26 is held in close proximity to the film 11 throughout its extension across the width of the film to its extended position. 7

- Suitably mounted in t ,e bottom or back portion of the camera casing, and opposite to the shafts 13, 14, is a plate 28 of suitable conducting material of length approxima' ly the the width of the film 11, and of any desired width. For the purposes of illustration, 1 have shown this plate as being sufliciently wide to allow several lines or written matter, but my invention is not to be limited in this respect.

f The plate 28 is connected to one terminal of asource of current such as a battery '29. The other terminal of the current source is connected to the filament of the el ctric light bulb which in turn is electricallycou nected in series to the lazy tongs members 16, 19 in any suitable manner. The current flows through the members 16, 19, the shafts 13, 14, lazy tongs 15, 18, to the conducting point 30. The shafts 13, 14, project sulficiently above the surface of the camera casing to hold the lazy tongs elements 15, 18, when in extended position a sufiicient distance from the surface of the camera casing to hold the stylographic device or pencil 30 normally out of contact with the conductor plate 28, but the resiliency of the elements 15, 18, allows the pencil or point to be depressed to make contact with the plate 28 and thereby complete the electric circuit and cause the lamp 26 to light.

The battery may be carried in any suitable place either exteriorly or internally with respect to the camera casing. I have shown one arrangement wherein the battery 29 is inserted in a pocket in the casing 7. In this instance, I provide a door 32, hinged at 33, to allow ready access to the battery, for the purpose of replacing the battery whenever it becomes depleted.

It is evident that when the writing device is not to be used, it is folded up as partially indicated in dotted lines, Fig. 1, into a small amount of space, it being under stood, that when the outside lazy tongs elements are thus folded up toward their fixed point, the inside elements are likewise folded up and, together with the electric light bulb, are out of the scope of the light rays which cause the print on the film.

The operation of the device is comparatively simple. Assuming thata film has been exposed, and the picture taken, and it is desired to inscribe on the picture taken, the lazy tongs arrangement is in its folded or condensed position. The operator takes the knob or handle 25 and extends the lazy tongs arrangement to its extended position, as shown in Figs. 1 and 2. The inscription is then made as in the use of an ordinary pantograph pencil, pressing down upon the handle 25 sufiiciently to form contact between the point 30 and the plate 28. Aslong as this contact is maintained, the electric light bulb remains lighted and as the bulb passes close to the film, the light rays pass from the pin point opening 27 through the light excluding film cover or coating over the bulb. The light rays passing over the film in identical reproduction of the movement of the point 30, expose that portion of the film that the light rays pass over, and consequently, when the film is developed, the autographed inscription is reproduced on the developed negative. Each print produced from the film or plate will of course bear a reproduction of the autographed inscription.

lVhile I have shown and described in de tail one construction and arrangement emskilled in the art without departing from the broad scope of my invention as defined in the claims and while I have shown and described my invention as applied to a film camera or a kodak it will be understood that my invention is not to be limited thereto, as the same is applicable to plate cameras, motion picture cameras, and, in fact, to any type of camera used in modern photography.
