CARL JESINGHAUS, OF DUSSELDORF, GERMANY.

PRINTERS LOCK-UP.

SPECIFICATION forming part of Letters Patent No. 498,935, dated June 6, 1893.

Application filed July 22, 1892- Serial No. 440,903- (No model.)

To all whom it may concern.-

Be it known that I, CARL JESINGHAUS, a subject of the German Emperor, residing at Dusseldorf, Germany, have invented certain new and useful Improvements in Printers Lock-Ups, of which the following is a specification. I

This invention relates to a printers lock up for preserving live or dead typematter such as used for ordinary printing or for ornamen-.

tal, curved or border printing.

It consists in the various features of improvement more fully pointed out in the claim.

In the accompanying drawings: Figure 1 is a side elevation of my improved printers lock up; Fig. 2 a top view thereof; Fig. 3 a side view of bar .9; Fig. 4: a side view of bars, and Fig. 5 a top view thereof.

My improved lock up is composed of four bars 3, s, s s, which are toothed or have toothed ends adapted to interlock. The bars, and also the bar 8 has its teeth projectingin the same direction at both ends. The bar 8',

and also the bar .9 has its teeth projecting in opposite directions at both ends. The teeth should be beveled toward the inner side of the in closed space so that the m atter iscompressed, as the lock up is closed. Each tooth should have the width of one pica and the bars should be of such a length that the space inclosed always forms a multiple thereof.

To close the lock up, the bar .9, is placed 7 with its teeth up and the bars 8', 8 are placed upon and into engagement therewith. Next the bar 5 is placed with its teeth down and into engagement with the upwardly projecting teeth of bars 8, s

- By the use of several teeth on each bar, the size of the inclosed space may be altered. Of course, each printer should have bars of different sizes, so that each set is used within specific limits.

What I claim is A printers lock up composed of four toothed bars, of which each of two bars has its teeth projecting in the same direction, while each of the other bars has its teeth projecting in opposite directions, substantially as specified.

In testimony whereof I have signed this specification in the presence of two suhscribing witnesses.

CARL J ESINGHAUS.
