MEANS FOR HOLDING PRINTING-PLATES ON CYLINDRICAL OR FLAT SURFACES.
SPECIFICATION forming part of Letters Patent No. 427,366, dated May 6, 1890.
Application filed September 23, 1889. Serial No. 324,788. (No model.)
To @ZZ whom t may concern:
Be it known that I, HENRY ROBISCHUNG, of Chicago, in the county of Oook and State of Illinois, have invented new and useful Improvements in Means for Holding Printing- Plates on Cylindrical or Flat Surfaces, which invention is fully set forth and illustrated in the following specification and accompanying drawings.
1o The object of this invention is to provide in printing-machines means for securing short plates upon plate-holders, beds, or turtles when a design smaller than the whole surface of the holder, bed, or turtle is to be printed,
so that only the surface of the short plate to be printed from will be presented at the printing height, the remainder of the surface being kept from cont-act with the impressioncylinder and inking-rollers in typographie zo printing, as well as from those and the waterrollers in printing from zinc or other plates by the lithographie method.
The invention will rst be described in detail, and then particularly set forth in the 2 5 claims.
In' the accompanying drawings, Figure 1 illustrates a longitudinal vertical section of a flat-surfaced bed or plate-holder; Fig. 2, a plan of the same partially broken away 3o to show the construction of the straining-levers and their dependencies, and Fig. 3 a longitudinal vertical section of a cylindrically-surfaced bed or turtle. Fig. 4 illustrates a portion of Fig. 1 in enlarged section, and
3 5 Fig. 5 a modification of detail hereinafter particularly described.
In said figures, the number 8 indicates the bed or turtle; 2, the short plate to be printed from, turned into an open hem at the ends, as
4o shown at 3 and 13. The plate or bar 4 issecured to one end of the bed or turtle, forming, with a part of the surface of such bed or turtle, a thin groovefor the reception of the turned hem at one end of the printing-plate 2, the other end of which plate is'similarly turned into an open hem, as at 13. The printing-plate 2 is underlaid by a plate 14 of the desired length and the proper thickness to keep the surface of the printing-plate higher 5o than the auxiliary holding-plate 15, hereinafter described, the surface of the bed or turtle 8 being made to the proper height to permit of this. The straining-levers 5, provided With straining-screws 7, are fulcrumed at 9, and
carry a plate or plates 6 on their upper ends, 5 5
formed for the reception of the turned hem of a plate, as shown at 17, similar to that shown at 3. The auxiliary plate 15, preferably of thin steel, is also turned into open hems at its two ends, as at 16 and 17. The hem 13 of the printing-plate 2 and the hem 16 of the auxiliary plate 15 are hooked into each other, andV the hem 17 of said auxiliary plate is hooked into the straining-levers 5, as shown at 17.
The dotted lines 18 show the printing-line in each case extending over the auxiliary plate 15, below which line it is designed to keep the auxiliary plate to prevent the contact of the same with the impression-cylinder 7,0 and the inking or Water rollers, as above mentioned.
The modification shown in Fig. 5 exhibits a metal splicing-piece orv link 18, made preferably of a thin strip of steel. Said splicingpiece may be used, as shown, to connect, by means of its double hem-hook or channel shape, a printing-plate 2 to the auxiliary or straining plate 15, instead of connecting the plates 2 and 15 directly together, as shown in 8o the other figures. The plate 15, if the link 18 be used, may be made of old or other inferior metal-such as zinc-unfit to be used for a printing-plate, and thus a saving effected by the interposition and use of said link. The 8 5 smaller the printing-plate 2 is required to be the greater the saving, whether the link 18 be used or a steel plate 15 be used without said link.
It is evident that the shortlink of Steel is cheaper than a long strip 15 of the same metal; hence, the link being of steel and the plate 15 of old zinc, the cost of a steel plate 15 is practically eliminated by interposing the steel link 13. The plate 15 cannot be 95 made of zinc and used without the link 18, because the two zinc plates will not hold by their hems together. One Zinc and one stiffer metal must interlock.
By this invention auxiliary plates, such as Io:
l5, and underlaying-plates, such as 141nay be kept on hand conforming to the various lengths of sheet or design required to be printed, and a printing-plate, such as 2, of any desired length, from the least up to and including a full-length plate, may be readily placed and strained on the bed or turtle in an expeditious manner.
The underlaying-plates 14, by being made only of the size of the surface devoted to making the impression, perform, among others, a very important oTioe-mamely, that of preventing the Water from mixing with the ink, and thus diluting it and making the impression pale or indistinct, which happens when small surfaces of large sheets of zinc are Caused to do the printing Without the interposition of such plates as 14.
The straining-levers 5 and their adjustment form no part of this invention.
H. ROBISCHUNG.
