COMPOSITE PRINTING SLUG'.

Application filed July 19,

This invention relates to a printing slug formed of a thin metal member having printing characters and mounted on the top of a suitable body; these two parts together to stand type high.

The object of the invention is to provide such a composite slug in a form which may be rapidly and economically produced and in which the body portion may be used repeatedly, thus obviating the necessity of casting a body in connection with the formation of the characters. I thus provide a composite slug which may take the place of the usual linotype slug while avoiding the necessity of operating a linotype machine.

My composite slug preferably comprises an embossed sheet metal strip having in wardly flanged edges and a body slightly less than type high having its upper portion provided with an overhanging rib slightly less than body width. The embossed strip is mounted on top of such body by being slid lengthwise thereon, and when so mounted has its face stand type high while its edges do not overhang the sides of the body.

The bodies of my composite slugs may be cast or otherwise produced and maintained in stock. The embossed strips may be made by a suitable embossing machine, such as one adapted for office use. lVhen the printing strips are produced they need simply to be mounted on the bodies and the slugs locked up in the chase, in conjunction with linotype slugs, type or electrotypes, if desired. After printing, the strips may be removed from the bodies and the bodies used with other strips.

In addition to the ease and rapidity with which printing slugs may be produced by my invention, I may also mention the great saving in idle metal during the delays incident to completing the printing operation. With my slugs the printing faces may be produced at a convenient time but need not be mounted on the bodies until the printer is ready to print. I thus avoid the necessity for holding large quantities of type metal standing, which is a constant source of annoyance to printers and in the aggregate amounts to a very material investment in metal. Moreover, in case it is desired to preserve the matter for subsequent impressions, the embossed strips may be simply slid 1924. Serial No. 727,078.

onto a temporary holder and stored economioally at a great saving in space.

My invention is hereinafter more full explained in connection with the drawings and the essential novel features are summarized in the claims.

In the drawings, F5 g. l is a perspective of several of my composite slugs resting on a suitable support in conjunction with an ordinary line slug; Fig. 2 is a plan of several of my slugs mounted side by side in a suitable chase; Fig. 3 is a vertical section, as indicated by the line 3-3 in Fig. 2; Fig. 4 is an enlarged fragmentary end view of the upper portion of one of my slugs; Fig. 5 is a fragmentary end view of one of my slugs in conjunction with an ordinary line slug.

As shown in each of the figures, 10 indicates the body of my composite slug, which is substantially a parallelopiped and some what less than type high, but having grooves 11 in its opposite sides adjacent the top to provide a neck portion 12 surmounted by an overhanging head 13. The end edges of the overhanging or dovetailed portion of this head are preferably inclined downwardly as shown, particularly in Fig. 4.

The embossed strips of the composite slugs are designated 20. Each consists of a thin ribbon of metal having thereon a single row of upwardly embossed printing charaoters and having the edges 22 flanged downwardly and inwardly. Such strip is accordingly ada )ted to slide onto the dovetailed upper en of the body with the flanges snugly engaging the under face of the dovetailed portion. The thickness of the strip, plus the amount the characters are raised above the strip by the embossing, is equal to the amount the body is less than type high, so that the total height of the composite slug is the standard type height. The extreme width of the embossed strip is no greater than that of the body and preferably slightly less than the width of the body, as illustrated in Fig. 4:, so that there may be no question of the bodies locking up tightly in the chase in the usual manner without any lateral pressure being exerted on the strip.

The bodies may be made of any suitable metal and in any desired manner, but I prefer to cast them of type metal in a suitable slug casting machine equipped with a separable mold to form the grooves in each side.

The embossed strips may readily be of aluminum and can be efiieiently produced by a suitable keyboard embossing machine, such for example as that shown in application No. 535,311, filed Feb. 9, 1922, by Glitton Chisholm.

The embossed strips may fit the bodies with suflicient freedom to allow them to be readily shoved manually thereon and they may if desired be prevented from longitudinally shifting by a suitable inward dent, provided by a center punch as indicated atfla in Figs-2 and 8'.

In Figs, 1 and 5', I have illustrated at 30, a standard linotype slug, the characters 31 of which stand the same heigl'it-to-paper, as the characters 21 of the adjacent embossed strips 20.

Having thus described my invention, 1 claim:

1. A composite printing slug con'ipri'sing a bar having parallel sides and adapted to stand on a narrow edge and said bar being formed at its upper edge with an overhanging head and asheet metal: strip having an upwardly embossed line of characters and mounted on the head and having edge flanges underhanging such head.

2. A composite printing slug comprising a cast metal bar having an integral rib along its top narrower than the bar and with its edges converging downwardly, and a metal strip embossed with a line of upwardly projecting characters and having downwardly and inwardly flanged edges, the strip resting on top of the rib and the flanges of the strip extending beneath the overhang or the rib, the thickness of the bar beneath the head being greater than the transverse dimension of the embossed strip and the combined height of the body and strip being standard type height.

In testimony whereof, I hereunto allix my signature.

ALBERT R. GOLDRICK.
