P.V 'FLGER TYPE LINE TRIMMING MACHINE Filed July 7, 1939 3 Shoats-Sheet 3 Patented Jan. 14, 1941 UNITED STATES TENT FFICE Application July 7, 1939, Serial No. 283,305 In Germany July 23, 1933 6 Claims.

This invention relates to a machine for calibrating type lines produced on matrix line composing and type line casting machines.

Type lines produced by such machines cannot be properly assembled without special fitting, because they differ as to height and thickness, due to the construction of the known matrix line composing and type line casting machines, and possess, moreover, undesirable burr. It becomes -therefore necessary in setting up matter composed in such lines to adjust them by means of interposed pieces of paper, but this operation takes up much time and is open to the further objection that the paper often works out from between the lines during printing and thereby spoils the print.

It is the object of the invention to eliminate these drawbacks by bringing type lines produced on machines of the kind mentioned after complete cooling to size in one operation by subsequent machining with the aid of stationary knives.

In a machine according to the invention for bringing type lines to size, the stationary knives are so arranged relative to one another that one of the knives removes the burr positioned laterally of the top of the plain face of the line, another one acts on the base of the line to insure uniform height and a third knife cuts the ribbed line face parallel to the bearing surface exactly to the typographical measure.

The invention is illustrated by way of example in the accompanying drawings, in which Figure 1 is a front view of the machine;

Fig. 2, atop view, partly in section, of Fig. l;

Fig. 3, a vertical cross section on the line 3-3, cf Fig. 2;

Fig. 4, a cross section on the line 4 4, of Fig. 2; and

Figs. 5 and 6 show, respectively, in cross section on an enlarged scale, a type line in unfinished and finished condition.

A pile of lines Z taken out of the receiving galley of a type-setting machine is placed on a transport table I in such manner that a slide 2 moved by a weight 3 presses the lines against a bearing or application surface 4, as shown in Fig. 2. The drivers 5 of a conveying chain 6 push the lines Z along a guide path I. Instead of a chain an endless band or a slide moved by an eccentric may be employed. The guide path 'I is provided with a rear jaw 8 and an upper covering bar 9, which are firmly secured to the base plate I0, and also with a front jaw II firmly connected with the rear jaw 8 and supporting (Cl. SMI-25) springily disposed pressure bars I2. The rear jaw 8 is fitted with a springy pressure bar I3 which abuts against the underside Z5 of the line Z. The springiness of the pressure bars I2, I3 permits their adaptation to unevennesses of the line Z and to press the latter against the stationary rear jaw 8 and the lower face I4 of the covering bar 9, as indicated in Fig. 4. The lines Z are brought into the guide path 'I so that the top Z6 bears against the lower face I4 of the bar Q and the plain face Z2 against the inner face 'I of the jaw 8.

Each line Z' passed through the guide path 'I between the pressure bars I2, I3 is acted on by three knives I5, I6, I'I. The knife I5 serves for removing the burr Z3, shown in Fig. 5, formed at the top Zs below the character. The knife I'I Works on the ribbed line face Z4, and the knife I6 is intended for operating on the underside Z5 to insure uniform height of the lines. The knife I'I trims the ribbed face Z4 parallel to its application face Z2 to the exact typographical measure, which is of particular importance for the assembling of the matter.

It is possible of course to calibrate and trim also ribless lines in the same manner.

Having been gaged as described, the lines Z slide behind the guide path I upon the inclined collecting table I8 and are pushed aside by a slide I9 to make room for the next batch. The slide I9 is arranged on a double lever 2l oscillatable at 2,!! by means of a shaft 22 and a cam disc 23. A displaceable stop 24 serves as abutment to prevent the finished lines from tilting. The lines Z' are assembled on the table I8 in the order fed to the table I. Drive is effected by a pulley 25, though the machine can be actuated also by a hand wheel 26, particularly for accurate adjustment.

The machine according to the invention is preferably connected with a typesetting machine.

I claim:
