STEPHEN H. HORCAN, OF JERSEY CITY, N. J., ASSICNOR To THE AMERICAN PRESS AssOCIATION, OF NEW YORK CITY, CHICAGO, ILL, CINCINNATI, OHIO, BUFFALO, N. Y., AND BOSTON, MASS.

PRINTING-PLATE.

SPECIFICATION forming part of Letters Patent No.341,332, dated May 4,1886.

Application filed November 30, 18:5. Serial No. 184,334. (No model.)

T at whom it may concern.-

Be it known that I, STEPHEN H.'HORGAN, a citizen ofthe United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Printing-Plates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it [0 appertains to make and use the same.

My invention relates to. improvements in printing-plates; and it consists in a light or thin printing-plate made of any suitable material provided with a thin backing of wood,

I5 composed of sheets of veneer cemented together, as hereinafter described and claimed.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side edge view of myinvention, and Fig. 2 a cross transverse section.

In the drawings, A is a thin light printingplate, which may be an electrotype-shell, a thin stereotype-plate, or any thin plate produced by stamping or by any other mode,

2 composed of metal or of celluloid, or similar material.

13 is the veneer backing, which, as illus trated, is composed of three thin sheets of ve-' neer cemented together.

The printing-plate A is applied to the backing B by first giving the wooden backing a top coating of suitable glue or cement, and then pressing the plate thereon and turning the edges 2) of the plate over the edge of the 5 backing.

The object of the veneer backing is to furnish to the plate mentioned a stiff and light support,which affords to such plate greater safety in handling and transporting, and reuders. it of greater adaptability for certain 40 special purposes of a printingplate than when the latter is constructed simply as a shell, Or when heavily backed by metal or wood, as has heretofore been the practice.

I have shown the veneer backing as com- 5 posed of three thin sheets of wood; but this number of sheets may be varied and the grain of the different laminze may be made to run crosswise of each other, if desired; and in connection with the veneer a textile fabric might be also employed, if desired; or, in place of the two or more thin sheets of veneer,

a single sheet of equivalent strength and thickness may be employed.

It is not necessary in any case to provide the printing-plate with edges or flanges I), nor is it necessary to glue or cement the plate to the backing, as the plate may be made of plastic meterialsuch as celluloid-in which case the plate,when plastic, may be pressed onto the backing, and the parts held securely together when such plate becomes hard.

\Vhat I claim, and desire to secure by Letters Patent, is-

An electrotype-shell or other light thin printing plate provided with a light thin backing composed of two or more thin sheets of veneer, constructed and arranged as herein described.

In testimony whereof I affix my signature in presence of two witnesses.

STEPHEN H. HORGAN.
