Definitions

  • This invention relates to typographical machines of the class wherein matrices are stored in inclined magazines from which they may be selectively released and gravitate through a vertically partitioned passageway onto the upper stretch of a constantly moving endless belt which delivers them to an assembler mechanism by which they are driven into an assembly elevator after which the characters on said matrices are reproduced either by casting a type bar or by photography.
  • This invention is particularly adapted to machines wherein the release of matrices is effected by automatic mechanism such as the well known Teletypesetter composing machine operating unit which is capable of releasing matrices at a much greater frequency than by hand operation of the usual keyboard.
  • a pair of spaced narrow belts are provided, in place of the usual full width single belt, and a vacuum chamber is disposed beneath the upper stretch of the belts in such manner as to provide a support therefor. Also, the vacuum chamber is provided with a raised rail portion which is disposed between the two belts and serves as a separating guide.
  • the guide rail is provided with holes in communication with the vacuum chamber and thus, when vacuum pressure is applied, the matrices are drawn against the belts and attain belt velocity very quickly thus greatly reducing the frequency of transpositions. Furthermore, by causing matrices to attain belt velocity quickly, the likelihood of spaceband transpositions is very greatly reduced.
  • the required vacuum pressure may be conveniently provided by connecting the vacuum chamber to the intake side of the usual mold cooling blower of a line casting machine or by providing a suction pump for a photographic composing machine.
  • Another object of the present invention is to minimize the frequency of matrix transpositions during composition.
  • a further object of the present invention is to minimize the frequency of spaceband transpositions during composition.
  • FIG. 1 is a fragmentary front elevational view of the arrangement of the present invention in relation to the usual assembler front and assembly elevator of a line composing machine.
  • FIG. 2 is a fragmentary plan view taken on line 22 of FIG. 1 and shows the disposition of the vacuumchamber suction holes in relation to a matrix and the matrix delivery belts of the present invention.
  • FIG. 3 is a fragmentary sectional view taken on line 3-3 of FIG. 1 and shows the relationship between a matrix and the vacuum chamber and matrix transporting belts of the present invention.
  • a magazine 4 containing matrices 6 is disposed above and aligned with an assembler front 8 having vertically disposed spaced partitions 10 the lower ends of which are curved to the left.
  • a pair of endless belts 12 and 14 mounted in space relation upon a pair of grooved pulleys 16 and 18 said pulleys being adapted to rotate constantly while the machine is in operation.
  • a vacuum chamber 20 which is so constructed and disposed as to provide a support for the upper stretches of the belts.
  • the upper surface of vacuum chamber 20 is provided with a raised rail 22 which is disposed between and serves to separate the belts 12 and 14.
  • the upper surface of rail 22 is so disposed, in a plane beneath the upper surface of belts 12 and 14, that it will not contact the body portion of a matrix 6 while it is being transported by said belts.
  • the rail 22 is provided with a plurality of air passages 24 in communication with vacuum chamber 20 which is, in turn, connected by a conduit 26 to a suction pump 28.
  • FIG. 1 Also shown in FIG. 1 is a usual matrix deflector plate 30, a star wheel 32, an assembly elevator 34 and a spaceband box 36.
  • matrices 6 When matrices 6 are selectively released from magazine 4 they gravitate through assembler front 8 and are guided and deflected by partitions 10 onto the upper stretches of belts 12 and 14 which are continuously moving from right to left toward the assembly elevator.
  • suction pump 28 creates vacuum pressure in chamber 20 thereby causing air to be drawn through passages '24 at a high velocity.
  • the air being drawn through the passages 24 in rail 22 will draw said matrices into engagement with belts 12 and 14 and, as the belts transport the matrices to the left toward the assembly elevator 34, the air being drawn through the successive passages 24 will tend to hold the matrices in firm contact with the belts.
  • a tape-controlled, high speed typographical composing machine the combination of a magazine containing matrices which are selectively released therefrom, an assembler front extending downwardly from said magazine and having generally vertical passages of dilferent lengths opening, at the bottom of said front, at successively spaced apart locations and adapted to have the selectively released matrices fall therethrough, an assembler, conveyor means moving along an inclined path under the bottom of said front to said assembler to carry the matrices to the latter in the order in which the matrices are selectively released, and means creating a positive air pressure difierential between the pressures respectively above and below said conveyor means along at least the portion of the latter passing under the passages of said front remote from said assembler so that matrices falling onto said conveyor means through said passages remote from the assembler are made to adhere to the conveyor means for avoiding rebounding and slipping of such matrices relative to the conveyor means and thereby preventing transposition on the conveyor means of matrices released successively
  • said conveyor includes at least one endless belt guided to have an upper run along said inclined path
  • said means creating a positive air pressure differential includes a rail extending along side of, and slightly below said upper run of the conveyor, said rail having upwardly opening orifices therein, and means applying a suction to said orifices to cause a downward flow of air into the latter.
  • said conveyor means includes a pair of parallel, laterally spaced apart endless belts guided to have upper runs along said inclined path, and wherein said means creating a positive air pressure differential includes a rail disposed between said upper runs at a level slightly below the latter and having upwardly opening orifices, and means applying a suction to said orifices to cause a downward fiow of air into the latter.
