Abstract
Abstract A photocomposing machine includes a pair of interchangeable discs removably mounted for rotation on a common shaft, a pair of prisms which act as a beam splitter for merging character images from each disc along a common optical path, the prisms also being designed such that all images have a single orientation when they arrive at an image-receiving surface, a lens turret for changing size, and a style-shifting mechanism which moves the discs in unison. In addition, a lens positioned in the optical path between the prisms and the lens turret is adapted to form a first (or intermediate) aerial image of each projected character prior to the character image being focused on the image-receiving surface.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
185 words
A photocomposing machine comprising: a pair of discrete, rotatable character carriers, each of said character-carriers having a multiplicity of characters positioned thereon, said character carriers being mounted for rotation about a common axis, means for moving both of said character carriers in unison for the purpose of shifting from one style to another on each of the character carriers, means for selectively illuminating characters on each of said character carriers, a sensitized surface for receiving images of selected characters projected form each of said character carriers, the character images projected from one of said character carriers having a first orientation, and the images projected from the other carrier having a second orientation, optical means for reorienting the character images projected from one of said character carriers, in order that all of the images projected onto said image-receiving surface will have a single orientation, said reorienting means including means for merging said character images along a common path, means for changing the size of said merged character images, and means for spacing said images on said image-receiving surface in order to form lines of composition thereon.

Claim 3
Dependent Claim
32 words
The machine of claim 1 in which said rotatable character-carriers comprise interchangeable discs removably mounted on a common shaft, both of said discs having a plurality of concentric circles of different styles.
