at one time, polished simultaneously, 'and' imprints taken from all of them in one impression.

Another object of the invention is to provide an engraving-plate holder in which engraving plates can be held rigidly against lateral movement without the use of locking attachments usually employed in printing and engraving shops, and in a manner to avoid leaving sharp edges exposed between the plates themselves and the contacting portions of the plate holder.

These and other objects hereinafter set forth are attained by the means illustratedV in the accompanying drawing, in which Figure l is a perspective view of the improved engraving-plate holder.

Fig. 2 is a longitudinal vertical section through the holder showing a series of engraving plates mounted therein, and

Fig. 3 is a transverse vertical section of the same, also showing engraving plates mounted therein.

Similar reference numerals in all of the figures of the drawing designate like parts.

The present method of printing name or other cards, usually from copper engravingplates, consists of taking a single plate and securing it to a suitable bed, then inking the one plate, next polishing the same, and finally making the impression. This slow and tedious method of engraving only one card at a time requires the full service of one engraver, and consequently makes the product costly, and in view thereof, it is one of the important objects of this invention, to provide a means for holding a plurality of separate engraved card-plates each containing a different inscription, and in a manner, whereby one engraver can ink, polish, and print a plurality of cards at one time.

This improved engraving-plate holder is preferably formed from a steel block of a Y* thicknessk ofv approximately .one-half an inch, and is formed on one side thereof with a` plurality of recesses 5, which are preferably formed by planing, and each recess is of adepth slightly more than the thickness of the engraved plates to be printed from, and of a width equal to the width of said engraved plates, and preferably of a length equal to the combined length of three individual plates, and forming a marginal border having vertical walls 6 around the holder, and divisional borders having vertical walls 7 vbetween the recesses. lVith a holder of this particular size, nine individ- Yual card-plates can be inked at one time,

and polished sii'nultaneously, and their inscriptions be transferred to a single sheet of paper or cardboard with one impression of the press. AfterV the required number of impressions have been made, the printed sheet is cut to the desired size of individual cards.

The recesses are formed slightly deeper than the usual copper engraved plates 8, so that a layer of suitable tag-board9 can be placed beneath thercopper plates, not only to forniva cushion for the plates, but also to build or elevate varying thicknesses of copper plates so that their upper surfaces will be flush with the upper surfaces of the marginal and divisional borders. Thus the upper exposed portions of the holder and the upper surfaces of the copper plates being flush, an operator, with his hands, or with the wiping cloth of a power press, can polish the whole number of plates at one time as a single unit.

' It is not necessary that the holder be 'completely filled with plates, as one or more can be secured therein if the occasion demands, and the holders can be made of varying sizes governed by the size of the plate-press used.

In operation, when an engraver is supplied with 'a plurality of orders for differently engraved cards, he places the engraved plates of the cards desired in the holder, first inserting the tag-board base to secure a flush surface, and if desired using wax to fasten the plates in position and prevent their accidental` displacement, and then the whole, as a unit, is inked and polished either manually or mechanically, and finally printed in the vusual manner, using only one sheet of paper or cardboard and afterward cut- Yting tothe desired sizes; I ILthis operation of printing nine cards in this manner, one

engraving printer 1does jthefworlr of4 nine Y Awith very little eXtra trouble, thereby decreasing the'cost of the product to a great degree.
