T0 all 'wizom it may concc'rn:

Be it known that I, UAnL HERMANN Cnnrs'rnn, a subject of the Emperor of Germany7 and resident of Berlin, Germany, have invented certain new and useful Impro-vcincnts in Linotype-ll'lachines, of which the following is a specification.

In line-type machines arranged for matrices with two or more superposed intaglio letters the slide or second elevator or other device which presents the composed line of matrices and space-bars to the mold or moldwheel for the casting of the linotype may be provided with either one or several horizontal ledges, on which the respective matrices, if raised, are made to slide and to rest with their lower1 rear cars or lugs as shown, for instance in Letters Patent No. 547,633 to P. T. Dodge. This arrangement presents the defect, that the alinement of the letters in the cast line when cast from raised matrices is soon rendered irregular, as the bottom faces of the lower ears or lugs of the matrices become worn away much more rapidly than the other supporting faces of the matrices, since'each matrix constantly and repeatedly drops and Strikes with its lower cars or lugsvarious machine'parts and the other matrices and when raised it is exclusively guided by its lower ears nearly during its entire passage through the machine. T he matrices with two or more superposed intaglio letters are supported on the bottom faces of 'their upper ears or lugs, like ordinary matrices with single intaglio letters, only in case their upper or uppermost intaglio letters are used for casting the linotypes. When the lower intaglio letters are to be used for casting the linotypes, of course the respective matrices require to be raised into their upper or any of their upper positions, so that the bottom faces of their upper ears remain at a height above the guiding Shoulders of the slide or second elevator or other device, and consequently the respective ledge or ledges in the device will have to engage beneath the lower rear ears of the matrices for supporting and guiding the letter. It is thus obvious, that after the bottom faces of the lower ears have been more or less worn away the several letters in the linotype cast from raised matrices will no longer be alined, they being more or less lowered in proportion to the 'any longer. w My 1nvent1on relates to nnprovements in liirotype machines of the class described, whereby the said defect is avoided in a most simple and certain ,manneiz i One improvement consists in providing each matrix having` more than one intaglio letter with one or several recesses above its lower` ear or lug in the side edge opposite' to the intaglio letters.

Another improvement consists Vin reclucing the breadth of the space-bars between the guiding rails either for a part onlyor for the whole of their length beneath their upper projecting arms.

i A third improvement consists in so arranging the single or several horizontal ledges in the slide or second elevator or other device as to enable itor them 'to engage either in the said recesses of the matrices or beneath not only the bottom of their lower rear ears but also a part of their bottom proper within the plane of the edges of the matrices. Insother words the horizontal ledge or ledges is or are enabled to coperate with parts of the mat-rices which are practically not subjected to any wear and tear during the passage of the matrices through the machine. V o y i I will now proceed to describe my invention with reference vto the accompanying drawing, in which-V Figure 1 is a Vertical cross section through a part of a mold-wheel with the mold and through the slide or second elevator or other device in a plane adj acent a matrix occupying its lower position, while another matrix behind the same occupies its upper position, all of the matrices being assumed to beV provided with only two superposed int-aglio letters, Fig. 2 is a similar section in another plane adj acent a matrix occupying its upper position, while another matrix behind the same occnpies its lower position, Fig. 3 shows one of the matrices, Fig. 4- shows a space-bar, the recess of which extends over most of its length, Fi LP shows a modified space-bar, the recess of which only extends over a part of its length, and Fig. 4b shows a further modification of the space-bar, in which the loreadth is reduced for the whole length up to one projecting arm.

iiinilar letters of reference refer to similar parts throughout. the several views.

a denotes the mold-wheel., Z) the mold7 and o the slide or second elevator or other device for presenting line of matrices to the mold. The latter provided with the known shoulders h lz. for support-ing and guiding the upper cars or lug f/t gt (Fig. 3) of the niatrices g when they occupy their normal lower position (F l), their faccs (/3 resting and sliding on the shcnilders h h. In this case their lower reaiI cars or lugs gl' engage beneath the ledge (Z, which serves for supporting and guiding these ears gl, if the matrices g are raised into their upper position (Fig. 2).

According to my invention all of the .matrices g are each provided with a recess i (lfig. 8) immediately above the lower rear ear glv and in consequence of this the ledge (Z is so much extended as to be capable of engaging in these recesses of the matrices g. The space-hars e are therefore reduced in their breadth, they being provided in the rear (left in Figs. 4 and 4a) side edge with a recess 78, which may extend either over a part of the length (Fig. la), or over most of the length (Fig. 4), or over the whole length up to one projecting arm f (Fig. 4th). Thus the space-bars are during the justification of the composed line permitted to freely move vertically past the extended ledge (Z. Some known mechanism is employed for raising the respective matrices g into their upper position, before they are pushed into the device c.

lt will be evident, that the extended ledge (Z engaging in the recess of any matrix g which is not rased will support the latter on the upper surface of the recess (Fig. 1). f however any matrix g is raised, the extended ledge (Z will engage beneath the lower rear ear (/1 and also on the part ,(/2 (Fig. 3) of its bottom proper7 within the plane of the edge of the matrix, which part is not subjected to any wear and tear. Thus the extended ledge (Z will come in contact with each matrix only on either of two faces which practically do not undergo any wear and tear during the passage of the matrix 'through the whole machine with the exception of the device 0. Thereby the alinement of the several letters in the cast linotypes is guaranteed for a much longer' time than hitherto.

lt is evident, that the invention can be applied to existing linotype machines, as it is only necessary to provide all of the matrices with the recess to reduce the breadth of the space-bars for a part or for the whole of their length up to their projecting arms f, and to provide the slide or second elevator or other device c with an extension of its ledge in any known manner, for example by taking od a part of the height of the ledge (Z and. attaching to the device c a plate of the required width.

It is further evident, that the invention can also be partially applied to existing linotype machines in which ordinary matricesl with single intaglio letters are eniployed, as it is possible to provide the device o with a detachable plate in place of the lower part with the ledge (Z. in case the lower cars of the matrices are worn away the matrices need then notbe cast awai', since the detachable plate can be replaced by another one of a greater width, which engages beneath a part (92 in Fin: of the bottom proper of the nia-trices that is practically not subjected to any wear and tear. In this manner the life of the inatrices can be further lengthened, until their intaglio letters are worn off.

In case the matrices are provided with more than two superposed intaglio letters, of course it will be necessary to provide them with more than one recess and this in a manner which is obvious to any expert. For example matrices with three superposed intaglio letters will require to have each two superposed recesses above the lower rear ear gl, and the slide c or its equimlent will require to have two superposed horizontal ledges d.

lt is essential that the matrices and space bars for each line should be secnrely clainped together at the mold and also that they should be accurately and closely prcssed or clamped against the mold, in order that no metal may escape between or around the matrices when the pump is operated. The ledge (Z is made to fit the notch of each matrix and to extend exactly to the bottom of the notch when thematrix is in casting position. Then thus proportioned the ledge operates as a part of the clamping devices to press the matrices firmly and uniformly against the mold. The space bars are reqnired to he not greater in width than the distance from the ledge to the plane of the face of the mold in order that they may be pnshed up during the just-ification of the line. On the other hand the width of the space bars should be equal to the width of the bodies of the matrices at the notches that is, their width should be equal to the distance from the bottom of the notch z' to the opposite side of the matrix. Then thus constructed the ledge (Z will press equally upon the space loars and matrices and hold them uniformly against the mold. The ledge (Z therefore serves to sustain the matrices at the proper elevations when presenting` them 'to the mold and also to assist in pressing the matrices and space bars uniformly against the mold to prevent any escape of metal along the inner face of the matrix line.

rl`he matrices and space bars .described herein are claimed, respectively, in divisional applications, Serial No. 694,858, filed May 1, 1912, and Serial No. 785,316, filed August 18, 1913.
