PRINTING-PLATE.

Specification of Letters'latent.

Patented May 31, 1910.

Application filed May 24, 1909. Serial No. 497,922. i

To all whom it may concern:

Be itknown that I, J OSEPI-I S. DUNCAN, a citizen of the United States, residing at Chi cago, in the county of Cook and State of Illinois, have invented new and useful Iniprovements in Printing-Plates, of which the following is a specification.

This invention relates to improvements in printing plates which are largely used by gas companies, telephone companies and other corporations who send out many bills regularly to the same customers, for printing the addresses on thebills and envelope. These addresses are stamped on the plate and the latter is removably-mounted in a suitable frame which may also carry a card bearing an impression of the address and any other useful information. The frames are generally arranged in drawers in accordance with a regular card index system and they are run through addressing machines and returned to the drawers without disturbing their arrangement. Lips, flanges or other engaging means are struck up or otherwise provided on the frames for holding the plates thereon. Examples of these plates and frames are found in my Patents No. 692,994 dated February 11, 1902, No. 853,538 dated Mayll, 1907 and No. 856,452 dated June 11, 1907. It sometimes happens that the projecting parts on the frame which are employed to removably secure the plate thereon become inked and smudge or mark the letter or envelop during the printing operation. To avoid this my present invention provides a late'of novel construction which raises the ace of the type thereon sufficiently above the projections on the frame to enable the inking device to apply ink properly to the type without touchlng these projections.

In the accompanying drawings illustrat: ing my improved printing plate Figure 1 is a plan view showing my improved plate in a frame. of the plate. Fig. 3.is an end view of the plate showing the frame in broken lines. Fig. 4 is an end view of a three line plate.

Referring to the drawings, 5 designates, generally, a metal plate provided with type characters 6 foran address or other desired matter. 'The lines of type are located on panels 7 extending longitudinally of the late and elevated above the edge flanges 8.

etween each pair of panels there is a rib ;ter or envelop. The longitudinal Fig. 2 is'a plan view of the back 9, the back of which lies in the same plane with the back of the flanges.

The plate is arranged on the frame 10 with the back of the flanges 8 and the rib 9 in contact with the face of the frame and the holding devices 11 of the frame enga ed with the flanges.- The raised ty e pane s elevate the type sufliciently to ena 1e an inking device to apply ink properly to the face ofthe type without engaging any Ipart of the frame and this avoids the ia ility of the frame becoming inked and markinglthe lets oulders 12 and rib Qstrengthen the plate which is important when the type are to be stamped because the plate must then be made of soft metal. If the plate has only one line of type there will be onl one panel and the rib 9'will be omitted; i it has several lines of type a rib is provided betweeneach air of panels. In Fig. 4 I have shown the p ate provided with three lines of type and with two ribs. The edge flanges 8 may be continuous, as shown, or broken, as illustrated in my Patent No. 856,452 dated June 11, 1907.

What I claim and desire to secure by Letters Patent is:.

1. A printing plate comprisin rality of elevate panels-\provi ed with printing characters stamped thereon, and a strengthening rib inte ral with the plate and disposed longitudinalf of and between the panels at the back 0 the late to form a strengthening support for t e plate between the panels. 7

2. A printing panels provi ed with printing characters stam ed thereon, and a.

rib integral with the ate and extending lon itudinally thereof between the panels, said rib being adapted to serve as a strengthenin rib for theplate and a support for the pane l l 3. printing ate compris' a urality of elevated anels, proi ide p printing characters, angles at either ed e of said plate, and a strengt ening rib, sai rib and flanges adapted to engage a printing frame and support said panels above the face of said frame.
