Definitions

  • a tapered plate is provided for use in conjunction with the tapered axially movable spacer shaft and the fixedly positioned spacer head of a Linotype machine.
  • the spacer head is protected and prevented from contacting the matrices when the shaft and the plate are assembled on opposite sides thereof. Axial movement of the assembly assures proper wordto-word spacing.
  • the oppositely facing tapered surfaces of the assembled shaft and plate are always parallel regardless of their axial position relative to the spacer head.
  • Means are provided for loosely coupling the plate and the spacer shaft with a permissable range of relative angular movement thereof.
  • the movable spacers heretofore employed in the mechanical composition of matrices for Linotype printing generally consists of two elements, namely: a tapered shaft having the apex facing upwardly, and a small head, shaped like a plate, which is guided and slides relative to said shaft.
  • the spacer is positioned between two adjacent matrices of any two successive words in a composition line, so that the spacers head comes in contact with one of the two matrices, while the tapered shaft comes in contact with the other matrix.
  • the spacers head comes in contact with one of the two matrices
  • the tapered shaft comes in contact with the other matrix.
  • the deposition of lead on the head of the spacer causes, with continuous use, an accentuation of the wear of the matrices and, consequently, a reduction in their life, besides rendering necessary, every 4 hours, the cleaning of the spacers with consequent lossesin time, labor and efficiency.
  • the present invention provides for an improved movable spacer for the mechanical composition of matrices for Linotype machines, which spacer, besides the tapered shaft and head of the type mentioned, comprises also a tapered plate positioned in front of the shaft so that the head is positioned protectively between the shaft and the plate.
  • the plate is provided at its lower extremity with a thickening shaped like a transverse, partial dove tail, so as to engage, upon suitable play, a corresponding seat provided in the shaft. This will permit angular displacements and will keep the plate parallel to the shaft, so as to permit, in cooperation with the head, the spacing between words.
  • the scope of the invention is, therefore, to provide an improved movable spacer which will completely prevent the deposition of lead on the head and to protect the head between the shaft and the plate so that the latter two will also be free from lead deposits during the composition of the lines.
  • the spacer itself is not worn by the forced and continuous removal of layers of lead deposits by means of suitable removing tools which attack and damage the surface of the spacer;
  • the improved movable spacer of the invention comprises a tapered shaft 1 which is guided and slides longitudinally in a manner known,
  • a head 2 On the lower part of the shaft 1 there is a transverse seat 3 shaped like a dove tail.
  • the spacer also comprises an auxiliary plate 4, also tapered, having its apex facing upwardly and having in its lower extremity a transverse thickening 5 shaped like a dovetail.
  • the thickening 5 is seated v with considerable and suitable play in the corresponding seat 3 of shaft 1, while the upper extremity of said plate 4 remains 1 free.
  • the plate 4 is superimposed, in front, on shaft 1, so that head 2 is lodged between the two. Furthermore, plate 4 is engaged at its lower end to the shaft 1, but its connection is such that it may be displaced angularly when the shaft 1 is moved with respect to the head 2 during the spacing operation between words. Due to a pin 6, the plate 4 cannot become disengaged from the shaft 1.
  • the tapered configuration of head 2, shaft 1 and plate 4 is such that, regardless of the position taken by the shaft 1 and the plate 4 with respect to the head 2 (which is stationary), there is always a parallelism between the shaft 1 and plate 4.
  • the plate 4 has its upper portion slightly bent outwardly, so as to assure the adherence of its whole surface both against the head 2 and against the shaft 1.
  • the above-described spacer is positioned between adjacent matrices 7 and 8 of each pair of successive words in a composition line, as it is conventional'with Linotype machines.
  • the matrices 7 and 8 are thus in contact with the shaft I and, respectively, with the plate 4, while the head 2, which is guided by the respective ears 2' so as to engage itself as it is provided by themachine, remains protected between the shaft 1 and the plate 4.
  • Spacer means for use in the mechanical composition of matrices in a Linotype machine, said spacer means comprising the combination of:
  • auxiliary tapered plate having one end positioned in spaced opposition to and diverging from one end of said shaft on the other side of said spacer head whereby said spacer head is located intermediate said shaft and said plate and is thereby protected and prevented from contact with adjacent matrices;
  • coupling means for loosely joining the opposite end of said shaft and said plate, said coupling means including a partial dove tail joint defined by a recess in said shaft and positely facing tapered surfaces of said shaft and said plate being parallel to each other at all other times regardless of the axial relationship of said spacer head thereto.
