not a method. which can always be practiced satisfactorily by those not especially skilled, and: besides it; requires considerable. time. Also there is a'considerable proportion 'of each plate'left blank whi'clrrepresentsi so much Waste in' material and unnecessary Weight, both :of which: are important con siderations in large lists.

: My inventioniprovides aznovel method for makingprinting plates having: a single. line, as showir'in the drawing, or having a; plu ralityaoffilines, each plate adapted to; be detachahlyengaged with andwheldi byrretainingydevices onfithe frame. "The 'blank 15. for :making the plate is made: ofisuitable sheet materialvot a kind which willvenable printing characters to be embossed thereon, and which iswell iknown' in the" art. This blank may; be of. any size, andit'isidivided into. panels 16by parallel scoring 17'oneiits .face and 18 on its back. Thescore lines on the back are opposite the score lines on the front they are preferably v shaped as shown in Fig, 2,.and1'they cut intotheY-blank toia suflicient idepth. so that the panels may 'be easilyseparated bypressure of the; fingers but are" connected together so that thebl'ank can be ehandled without accidental separation or thetpanelsr The margin panelsll6 arewof-"suifici'ent width to accommodate the jawswhich hold them in the embossing machine, and when the embossing operation is -compl'eted they are broken oiirand: discarded. "The type panels 16 between the margin panels 16 are narrow but of suitablewidth for the type characters 'so that the embossed panels can be mounted on i the frame in proper line spacing. It isi found in practice' 'thatthe type lines can be embossed: on the blank, Fig. 7 invusualiiline spacing-and still leave enough materialist the margins of eachtype line'panel forengagementwith the retaining device oni the. frame. It is difficult to represent the exact dimensions and proportions in the pen and ink'drawings,;but =ll3Wlll be understood that the object is to have each panel as narrow as the enibossingoperation will permit with.-

out distortingorbreaking the metalvin the r embossing. operation, and in; practice has been found that the printing characters may be embossed in several lines on a scored plate and in close line spacing, and the type line panels may be separated and mounted in a frame in line spacing foraddressing. It may be that the scoring permits the metal to flow more easily in the embossing opera tion without distorting or breaking the plate. However, this may be, I do know that type characters, upper and lower case, can be embossed in several lines, in proper type spacing and line spacing, and when the panels are separated on the score lines each panel has sufficient side margin for operative engagement with retaining devices on the frame, these devices being arranged in close line spacing or otherwise, as desired. The

retaining devices are lips struck up from the frame 9 in pairs of rows. The lips 19 of the upper row of each pair are inclined downwardly, and the lips 20 of the lower row of each pair are inclined upwardly, Fig. 5, to provide an angular groove under each row of lips, discontinuous because of the spacing of the lips, to receive the top and bottom edges of the panel, and these edges may be tapered by reason of the scoring, as shown in Fig. 4, to more easily fit under the lips. The panel is light in weight, and

it is only necessary to provide a slight edge engagement with the retaining lips to hold the panel on the frame. Thus it is possible to form the type characters close to the edges of the panels, because only a slight projection of the panel beyond the type is required for engagement with the retaining lips; and in the V-shaped form of scoring shown, which I prefer, the extremity of the beveled edge is suflicient to effect this engagement. It will be understood, of course, that in actual practice the blank is quite thin, and the scoring is necessarily small transversely, but it is sufiicient to enable the panels to be readily separated without liability of distorting the panels.- The lips permit the panels to be inserted endwise and the use of light gauge metal for the plate blank; the inclined lips, forming discontinuous guide grooves for engagement of the tapered edges of the panel, enable the panel to be readily inserted and removed from the retaining devices of the frame or to be adjusted to any desired position.

WVhereas it has been customary heretofore to emboss an address or other form on a single printing plate, which leaves a considerable portion of the plate blank, representing waste material and unnecessary weight in the complete printing device, with my invention the panels may be embossed for their full length and divided as required after separation from other panels so that all, or substantially all, of each panel. may be employed far embossing, The type panels may be adjusted to any desired position on the frameto pro- ,material, made, up at the factory and supplied to the customer, or made up by the customers operator at odd times; and such stock material may be kept in storage for use as required, or it may be set up in frames for use as required. When a printing device is to be discontinued for any reason, the name and street address type panels may be removed and destroyed, the frame and the city and Salutation type line panels being preserved for furture use. Thus the invention reduces the cost and expedites the work of maintaining a list.

I have shown and described a printing plate blank and method of using the same for making printing plates adapted for use in a frame forming a complete printing device in accordance with my original lnvention, but I do not limit this invention to this particular use or adaptation, and reserve the right to practice the invention in making printing plates of any other kind and for any other purpose within the scope of the following claims:

I claim:

1. A blank of suitable material in which printing characters may be embossed to form a printing plate, said blank having oppositely disposed score lines dividing the blank into one or more panels on which printing characters are embossed with the character impressions located close to the score lines,

and a marginal panel adapted to be gripped 1 by the jaws of the embossing machine for holding the type panel in position to have characters embossed therein.

2. A blank of suitable material in which printing characters may be embossed to form a printing plate, said blank having oppositely disposed score lines dividing the blank into a. plurality of panels on which printing characters are embossed with the character impressions located close to the score lines, and a marginal panel at each side of the plurality of type panels, either of said marginal panels adapted to be gripped by the jaws of the embossing machine for holding the blank with a type panel in position to have characters embossed therein.

3. The method of making a printing plate which consists in providing a blank, scoring the blank in parallel lines on opposite sides with the lines on one side disposed opposite the lines on the other side to form narrow type panels, embossing printing characters on the panels With the character impressions I located close to the score lines, and then separating the panels on the score lines whereby the embossed panels areprovided with beveled edges to engage retaining means so that a plurality of embossed panels may be closely assembled to form a printing form with close line spacing.

4. The method of making a printing plate which consists in providing a blank, scoring the blank in parallel lines on opposite sides with the lines on one side disposed opposite the lines on the other side to form narrow type panels, embossing printing characters on said panels with the character impressions located close to the beveled edges of the panel, and then separating the panels on thescore *0 lines.
