- Specification of Letters Patent.
Patented April 10, 1906.
Application filed July 20, 1904. Serial No. 217,375.
To all whom it mag concern.-
Be it known that I, GEORGE N. PIFER, a citizen of the United States, and a resident of Cleveland, Ohio, have invented certain Improvements in Photographic Postal or Mailmg Cards, of which the following is a specification.
One obj ect of my invention is to provide a photographic postal or mailing card u on Which a positive picture can be produce by exposure of the card in the camera, a further ob ect being to permit of the developing and fixing of the picture after exposure without causin the card to be stained or otherwise .injured by the developing and fixing solution or so tions to whlch 1t is subjected.
In the accompanying drawings, Figure 1 is a view of the front face of the photographic postal or mailing card made in accordance with my invention. Fig. 2 is a View of the rear face of the same having the photograph produced thereon. Fig. 3 is an enlarged section taken through the treated portion of the card before the production of the icture, and Fig. 4 is a perspective view il ustrating a modification of my invention.
At the present time photographic postal or mailing cards are sometimes made by applying a sensitive gelatin film to the rear face of the card and rinting the picture upon this sensitized surfisice by exposlng the latter under the negative. 7
My invention renders unnecessary the previous preparation of a negative, the positive picture being produced directly by exposure in the camera;
The card may consist of any suitable material, preferably cardboard of a thickness, character, and size similar to those of a regulation United States postal card or private mailing-card.
To the back of this card, or to that portion of the same upon which the picture is to be produced, I apply a coating 1 of japan or other suitable enamel, which is then coated with a sensitized hotographic emulsion 1*, Fig. 3, similar to t at used for ordinary photographic dry plates or films, so that the card can be stored for use when required, or the cards prepared with the japan or enamel coating 1 can be used in the ordinary wet ferrotype process, the operator having simply to apply the collodion film to the japanned surface of the card and then to dip the latter into the usual silver-bathpreparatory to its exposure in the camera. In order, however, to prevent the developing and fixing solution or solutions to which the card is subjected after its exposure in the camera from staining or otherwise'injuring the front face of the card, or that portion of the same which is opposite to thej apanned and sensitized rear face,
coat said front face portion of the card with so that the strip can be readily wound upon a roller in the same manner as the film in an ordinarIv camera, the individual cards being readi y separated from the strip by reason of the transverse lines of perforations between successive cards. (See Fig. 4.)
Having thus described my invention, I claim and desire to secure by Letters Patent A photographic postal or mailing card having t roughout part of the area of one face of the same, an enameled surface presenting a suitable background for the production of a positive picture by direct ex osure in, the camera, and on the correspon ing portion of the other face of the card, a coating whereby the same is rotected from being stained or injured by t e solution or solutions used in developing and fixing the picture, the other portion of each-face of the card retaining its normal surface, substantiall as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses. I
GEORGE N. PIFER.
