Te Lennon 1T MAY cononnrn; y
Be it ,llnosylf'thnt I, THOMAS BARDON, of Brooklyn, in the countylol Kings, sind` State of New York, have invented and iiade a certain new and usefel'improvement in Engraving; :iz-nl I de heehy declare the following toihe a full, clear, and ex'act descripten ofthe `aid invention, .und the features that distinguish the same from ethei' medias-of engraving` v v Ewoud-engraving it is necessary that the surface he cuiJ away, und the lines left in relief tc heprinted from, In this character of werk itis `very diticult-'tcrfpick out the quadrangulnr spaces between fine intersecting lines, and in almost all engravings thereis more work required in cutting out' the surface on each side tif-.a line and leaving thatline than there` wculdllefin engraving the liuc itself. l
To facilitan: engraving, e'orts haveheretofure been malle to engreve by the use of wax or plastic material spread npun a 'plate of glass, and then'remnving such material Where 'the lines are required, and electro-typing to prfnluce the printing-plete or block.' In lthis character ci engraving, the direct picture is drnwn `and engraved', (not in reverse,} andthe surface for the ink is the clect1^o-type at the pontn'herc the plete has been exposed byrcmoving the nu.
AIn' this last-nr1uiedrsiyle of engraving, the small particles of )vaitlnttnre left projectinghctu'ccn intersecting iinesnre liable to brezil'. eirifV the` plastic compound is suflciently hard te he cut, and where 4the wax is of a softer nature it is apt te spread; thstheiorming of one line is aptto injure the next line, or partially lill up intersecting lines. f I' Y* The nature ,off my said inventioncousists in an engraving-surface formed of a soft and slightly brittle metal or metallic alloy, such as type-metal, fused upon the surface of n harderk metallic plate, such as hress or steel. By this mede of forming un engraving-surface, the liuesare prcduced by cutting the soft coating-metal flown to the surface of `the plate of which-it forms a contingenti the seid softer metal being cut with great euse, and being of` a character to ."utf'ie-eiy without s'piending under the tool, or breaking:y eff, thcengraving is performed Withgrcat facility and beauty, and the electro-type or cast made from the said plate in any desired C manner isV to heused-for printing from, its surface being a. plane coinciding with the surface of the harder metal,
onwliich the scftmctal has bfcn applied and engraved.
In the annexed drawing, a represents the surface to be engraved,for1ned of soit inetahnpfon the harder' motel plate c, the incisions .at c c, in the metal a, illustrating the mode of engraving through the metal a to the surface of c.
What I claim, and desire to secure'hy Letters Patent, is'- i, An engraving-surface, formed of typemetel, or its equivalent, fused upon the'surface'of a harder metallic plate,sucl1 as brass on steel, for the purposes and substantially as set forth.
in witness wl-uren?, I li ve hereunto set my signature, this seventh dnypf December, A. D. 1867.
