It will be understood that the constructional form of the apparatus herein described and illustrated has been chosen merely as a convenient example, and that modifications in the form of the parts may be made without departing from the invention.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:-

1. In a typographical line composing machine, the combination of an assembler having a channel wherein matrices are composed in line, the said assembler being movable from line receiving to line delivering positions, a matrix retaining pawl adapted to engage an ear of a matrix at the entrance end of the channel when the assembler is in the line receiving position, and means adapted automatically to move the pawl inwardly transversely of the channel during the movement of the assembler from line receiving to line delivery position, into engagement with a matrix ear located in advance of the said entrance end.

2. In a typographical line composing machine, the combination of an assembler having a channel wherein matrices are composed in line, the said assembler being movable from line receiving to line delivering positions, a matrix retaining pawl adapted to engage an ear of a matrix at the entrance end of the channel when the assembler is in the line receiving position, and means adapted automatically to move the pawl inwardly and outwardly transversely of the channel during the movements of the assembler respectively away from and towards its line receiving position.

3. In a typographical line composing machine, the combination of an assembler having front and rear walls forming between them a channel in which matrices are composed in line, said assembler being movable from line receiving to line delivering position, a matrix retaining pawl pivoted in the assembler rear wall and normally urged inwardly into the said channel, an arm on the pawl passing through and projecting rearwardly beyond said rear wall, and a cam member adapted to engage said rearwardly projecting arm whereby the pawl is permitted to move inwardly transversely of the channel and positively moved outwardly during the respective movements of the assembler from and to its line receiving position.

4. In a typographical line composing machine, the combination of an assembler having front and rear walls forming between them a channel in which matrices are composed in line, said assembler being movable from line receiving to line delivering position, a matrix retaining pawl comprising a pawl arm extending longitudinally of the said rear wall and a second arm passing through and extending beyond a slot in the said rear wall, a pivot for the said pawl located near the inner end of the said second arm, a spring normally tending to project the pawl arm inwardly transversely of the channel, and a stop adapted to engage the outer end of the said second arm to limit the inward movement of the pawl arm to definite extents appropriate respectively to the line receiving position and line delivering position of the assembler.

5. In a typographical composing machine, a combination according to claim 4, wherein the slot accommodating the rearwardly projecting arm of the matrix retaining pawl ,is formed with rearwardly diverging walls, one of which walls serves as a stop for the inward movement of the pawl arm in the line delivery position.

6. In a typographical line composing machine, the combination of an assembler movable vertically between line receiving and line delivering positions and having front and rear walls forming between them a channel in which matrices are composed in line, a fixed machine frame member at the rear of the assembler carrying guides for the vertical movement of the assembler, a matrix retaining pawl comprising a pawl arm extending longitudinally of the assembler rear wall and a second arm passing through and extending beyond a slot in the said rear wall, a pivot for the pawl located near the inner end of said second arm, a spring normally tending to project the pawl arm inwardly into the channel, and a stop adjustably secured to the said machine frame member, said stop having an inclined edge adapted to engage the outer end of the said second arm.

VERNON CHARLES JOSEPH HARRISON.
