MACHINE FOR PRINTING PHOTOGRAPHS.

Application filed July 16,

This invention relates to an improved machine for printing positive photographs from negatives'and is designed to provide a machinein which the positive can be given characteristics not found in the negative by interposing a distorting medium or means.

This added means is particularly adapted for producing grotesque effects such as one can Witness by looking at Oneself in a curved mirror. An ordinary picture can thus be transformed in the printing to a grotesque or humorous one. The machine is adapted to produce both still and motion pictures and the illustration and description set forth both types.

The invention is illustrated inthe acccomh panying drawings in which Figure 1 is a side view, partly in section' of a machine embodying my invention and adapted particularly for the printing of motion picture films and Figure 2 is a top view thereof. Figure 3 is a section on line 3-3 in Figure 1 and Figure 4 isa similar section of a modified form of rism. Figure 5 is a side view partly in sectlon of a machine for printing enlarged still pictures from a film. Figure 6 is a top view, partly in section, of the same. Figure 7 is an enlarged detail view of the prism used in this machine.

In the machine for printing motion pic- 'ture films I show a source of light, as the bulb 10 in a lamp house 11. The negative film is shown at 12 and it is advanced by any usual mechanism, (not shown) to pass across the rays. from the light, the rays being usually passed through a condenser lens 13. The rays are projected through the film onto the positive film 14 similarly advanced and in synchrony with the negative, the usual shutter 15 covering the positive at the movement of the films. I show a bi-prism 15 for transmitting the rays beyond the negative.

To secure a grotesque effect on the positive I interpose a means for distorting 'the rays as they are directed on the positive and the usual form is a prism 16 which has one face curved as at 17 to produce either an elongated or a flattened appearance of the picture. The curvature of the face 17 will govern the appearance of the picture, the persons and objects on the picture being tives that contain twin 1926. Serial No. 122,760.

shown either extremely tall or extremely fat or otherwise misshapen.

Thecurvature can be varied as at 18 (Figure 1) to produce an effect different from that produced by the curved face 17.

The machine for printing still pictures,enlarged from a film is substantially thesame as the above with such changes as are necessary to produce the enlargement. The machine illustrated comprises a lamp 10 or other suitable light source, and negative film is shown at 19 in the support 20. The positive is shown at 21 in a suitable support 22 and the bracket 23 is shown as the holder of the prism 24, similarto the prism 16 and aving the curved face 25. On the face 26 from which the rays emerge I place a lens 27 either integral therewith or by cementingand this enlarges the picture to the size required.

While the invention is applicable to printing various forms of photographs I have'illustrated in the drawing a machine particularly adapted for printing from nega pictures or images that are separately transmitted to the bi-' prism or merged or superimposed by the biprism on the mirror prism. In this way the resultant picture is, of .course, a single image with the effect of accentuated perspective that is present when viewing a 'stereosco ic picture. The particular mirror used int is construction, of course, duces a grotesque picture.

It will be evident that various changes can be made in the device without departing from the scope of the invention.
