CARL MUEHLEISEN AND AUGUST WALTER, OF BERLIN, GERMANY, ASSIGNORS TO MERGENTHALER LINOTYIE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

Specification of Letters Patent. 7

To all whom it may concern Be it known that we, CARL MUEHLEISEN, a citizen of the-United States of America, residing at 23 Ghauseestrasse, Berlin, N. 4, in the Empire of Germany, and AUGUST W ALTER, a subject of the German Emperor, residin at 5 Genterstrasse, Berlin aforesaid, have invented new and useful Improvements in Typographical Machines, of which the following is a specification.

The invention relates to a device for the distribution of specially thin typographical pieces, either matrices or type dies and hereafter called matrices in matrix composing and line casting machines, in which the matrices are raised singly by a pusher from the line and transferred to the distributor.

According to the invention, a special,

check is provided in the so-called distributor box, and which acts upon the lower ears of the matrices, in such a way that if several thin matrices are raised simultaneously from the line all except the foremost are retained in the line.

The drawing shows a constructional form of the invention.

Figure 1 is a View of the so-called distributer box provided with the subject of the invention; Fig. 2 is a view thereof from the left, all unimportant parts omitted; Figs. 3 and 4: show the device in operation (engaging a thin matrix in Fig. 3 and a thick one in Fig. 4;).

It is known that the matrices fed into the distributor box a by the second elevator, are raised therein one by one by the lifter 6 in order to be pushed on to the distributer screws (not shown in the drawing). So that only one matrix may be raised at a time, the said lifter is of such shape as to engage under the foremost matrix only to such an extent as corresponds with the thickness of the thinnest matrix. Furthermore, it is known that all matrices down to the thinnest have a notch h (Fig. 1) on their upper edge, reducing at that place the body of the matrix to the thickness of the thinnest. Above the lifter b, there is a stop 0 to engage each notch 7L, and the horizontal distance between the lifter b and the stop 0 does not exceed the thickness of the thinnest matrix or of the remainder of the matrix body reduced by the notch it, so that, if owing to sticking to each other, several mat- Patented Oct. 27, 1914.

rices are raised simultaneously, the stop 0 will retain the matrices which should not have been raised. It has now been found necessary for certain purposes, in particular for the production of spaced out composit on, to use very thin matrices, so called hair-spaces, in the machine. To reduce the distance between the lifter b and the stop 0 to such an extent that even such thin matrices are raised singly, would not be suitable, as the other matrices would also have to be notched deeper at 72 which would weaken them. The invention therefore provides on the side of the distributer box a a double lever cl rocking about a fulcrum e and having its nose continuously pulled downward by a spring f. The said nose works against the lower ears of the matrices, and is only so far away from the lifter 1') that only a single hairspace can pass between them. VVhen ordinary matrices are distributed, the lever cl is at every time taken along by the ear 9 of the matrix, and is moved upward against the pull of its spring f, out of its path, and when the matrix has passed it, it is pulled back into its original position. But when the hairspaces are distributed and in case a second matrix is taken along owing to friction, the lever cZ will act upon the lower ear of this matrix and retain it, as it is only taken along owing to adhesion or friction, so that only the foremost hair-space is raised. Of course the arrangement can be used also for other thin matrices and not only for hairspaces.

Fig. 3 shows the position in which the lifter b has raised the foremost hair-space and in which the second hair-space which was thereby taken along is retained by the lever (Z, while in Fig. 4 the raising of a thick matrix is shown in which the lever d has moved upward with the ear against the pull of the spring f, and slides off when the matrix has been raised high enough to fall back into its original position.

Having described our invention we declare that what we claim and desire to secure by Letters Patent is 1. The combination with a distributer box, of a reciprocating lifter, a lever having its end arranged at a distance from the lifter substantially equal to the thickness of the thinnest matrix, so as to permit the passage of such a matrix only therebetween, and a spring to hold the lever yieldingly in position. v

2. The combination of a distributer box, a reciprocating lifter, a lever to override the loWer ears of the matrices and Whose nose can rock upwardly parallelly With the said lifter but at a definite minimum distance from it, and a spring to return the said lever after it has been raised by anything raised by the lifter.

3. In a mechanism of the class described, the combination of a reciprocating finger to detach matrices individually from the line, and tWo members to prevent the detachment of more than .one matrix at a time, one memberbeing fixed and cooperating With matrices of a given thickness and the other member With matrices of less thickness.

4-. In a mechanism of the class described, the combination of a reciprocating finger to detach matrices individually from the line and twomembers to prevent the detachment of more than one matrix at a time, one mem: ber cooperating With matrices of a given thickness, and the other member With matrices of less thickness, and the second memher being movably arranged so as to be displaced by the passage of the thicker matrices controlled by the first member. I

o0 5. In a typographical machine, the combination of a line of matrices, a reciprocatmg finger to detach the leadlng matrlx from the line, and movable means ior restoring the following matrix to its proper place in the combination of a matrix lifting finger g and tWo members to override the matrices and prevent the detachment of more than one matrix from the line at a time, one of said members being located closer to the lifting finger than the other, for the purpose described.

In wltness whereof We have hereunto set our hands in the presence of two Witnesses.
