IMPROVEMENT IN PRINTING-PRESSES.
Specification forming part of Letters Patent No. 148,9 l2, dated March 24, 1874 application led February 6, 1874.
To all whom Iit may concern:
Beit known that I, BENJAMIN F. ALLEN, of Boston, and the State of Massachusetts, have invented a new and useful Improvement in Packing or Blanketing for Platens of Printing- Presses, of Which the following is a clear, full, and exact description, reference being had to the following specification.
My invention consists in placing upon the platen, or the cylinder of a cyli11der-press,when the cylinder is used as a platen, a thin sheet of any suitable metal as a platen-surface, With a sheet of rubber or other suitable elastic packing intervening between the platen-bed and the metal plate.
I rst place on the platen, or on the cylinder if a cylinder-press, a sheet of rubber or other suitable elastic packing, and over this .I place a thin sheet of zinc, brass, copper, or other suitable metal. On the metal sheet I place the tympan-sheet, or the sheet on vWhich the overlays may be pasted, when ters Patent, is
folder proofs; and the cuts themselves will Wear much longer, as will also the type, which are caused to press entirely on the plane of their face, and not upon the edges. The time gained in making ready When short numbers arerequired-for instance, in such Work as bill-heads, circulars, notices, and the like-will enable one person to do the Work of two persons using the ordinary blanket-packing.
It Will be evident from the foregoing description that, by my improved packing or blanketing, I secure all the advantages of elasticity, and at the same time secure a surface hard enough on the outside, next the type, to give a sharp, clean impression without showing much, if any, indentation on the printed sheet when examined on the opposite side. The form, when once made ready, will remain so until the Whole number is completed.
In the drawing, A represents a standard 5 B, aplaten-bed; c, the rubber or other elastic packing, and d the metal plate.
Having thus described my invention, what I elailn as new, and desire to secure by Let- In a printing-press, the combination, with the platen, of a metal plate as a platen-surface, having a sheet of rubber or other suitable elastic packing intervening between the platen-bed and the metal plate, substantially as and for the purpose set forth.
BENJ. F. ALLEN.
