MOLD-CARRIER OF MAGHINES FOR CASTING PRINTING-BARS.

Application filed July 13, 1911.

T '0 all whom it may concern:

Be it known that l, HEINRICH DEGENER, a subject of the German Emperor, residing at Hollmannstrasse 26, Berlin, S. in the German Empire, have invented new and useful Improvements in the Mold-Carriers of Machines for Casting Printing- Bars, of which the following is a specifica tion.

In a machine for casting printing bars, the complete casting combination consists of (a) a horizontal row of matrices held between two jaws, the formative cavities in the face of the said row constituting the mold for the printing edge of the printing bar; (6) a horizontally slotted mold for the body of the printing bar, fast on or to a mold carrier; and (c) a metal pot having a pump and a delivery mouth adapted to make metal-tight contact with one face of the mold. The mold carrier and mold are between the row of matrices and the delivery mouth of the metal pot. The other face of the mold must be presented to the row of matrices, or the latter to the former, for the purpose of placing the said face and the face of the row of matrices close to and opposite to each other and the slot and row of formative cavities likewise close to and opposite to each other. The presenting motion of the mold carrier may be circular about a fixed center as in the well known Mergenthaler machine known commercially under the trade mark linotype the mold of which is carried on a wheel; or linear as in the monoline machine; or arcual as in the Forth graphot-ype machine. But there must be a further motion between the mold and the row of matrices for the purpose of making their faces make operative (2'. 6., metaltight) contact with each other. This motion has up to the present been always only a linear one at right angles with the said faces. Now these two faces are intended to be always parallel with each other. If they were so, this further motion would always sufiice to effect the desired metal-tight contact. But accidental factors, such as changes in its temperature, frequently put the mold out of parallel; and when it is out of parallel, a perfect metal-tight contact is impossible, because as the connection between the mold carrier and the organ of the machine which supports it is a rigid one, the said mot-ion cannot be continued after Specification of Letters Patent.

one part, say one end, of the mold is in contact with the row of matrices.

The object of the present invention is to provide for a supplementary further motion automatically effecting a perfect metaltight contact between the said faces. It is attained by the substitution of a loose connection for the rigid one above mentioned, and one which is loose so as to rock either about an axis at right angles with the axis of the carrier or in any direction about a point in that axis, so that as soon as one part of either the mold or the row of matrices, is in contact with the other row or mold as the case may be, the other parts may continue to move .until all are in contact, whereby the. desired perfect metal-tight contact is effected.

The accompanying drawing illustrates one constructional form of the invention, the mold, mold carrier, and mold carrier support, being those of the Mergenthaler machine above mentioned. This form is characterized by the carrier having a capacity for being rocked in any direction about a point in its axis.

Figure l is a rear elevation and Fig. 2, a plan.

1 is the row of matrices; 2, 3, the two jaws; 3*, the mold wheel or carrier; 4:, a mold; 5, the horizontal slot in it; 6, the axle fast to the carrier 3 and turning in a bearing 7 hitherto rigidly connected by a bracket to a slide 8 working in a guide 9 fast on the machine frame 10 and which slide allows of the further motion above mentioned. The said bracket is replaced by the combination of a ball 11 fast on one end of a stout stem 12 having its opposite end fast to the bearing 7; a cup for the ball 11, one half of which is formed in a block 13 fast to the slide 8, the other half being formed in a second block 14 secured to the block 13 in such'a way that the two halves form a proper cup for the ball 11 after the manner of a cup and ball oint; and an outwardly flared hole 15 between the half cup in the block 14 and the face of the latter next the bearing 7, for the stem 12 to pass through and rock in any direction as far as the correction of the non parallelism between the mold 4 and the row 1, may require. This non-parallelism will show itself, if at all, at the end of the above mentioned further motion. The delivery mouth of the metal pot then makes contact with the rear face of the mold, next pushes the latter forward, thereby making the carrier and everything fast to it, rock until the faces of the mold 4 and row 1 are in the desired metal-tight contact with each other.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. In a typo-graphical composing machine, the combination of a mold and supporting means therefor, the said supporting means comprising a universal joint, so that the mold may rock about a plurality of intersecting axes in orderto insure its' tight contact with the other: casting devices.

2. In a typographical casting machine, the: combination of the frame, the mold carrier, and a universal joint. connection between them to permit the mold carrier to rock or tilt,

3. In a machine for casting printing bars, the combination of mold wheel; mold wheel bearing; mold for the printing bar; mold' wheel slide stem fast on the mold wheel bearing; and a loose connection between the stem and the mold wheel slide, adapted to allow the mold wheel to be rocked as operative contact between it and the row i of matrices, is being made;

t. In a machine for casting printingbars, the combination of mold wheel; mold wheel bearing, mold for a printing bar; mold ,wheel slide; stem fast on the mold wheel bearing; and a ball and socket joint between. the said slide and stem,

5. In a typographical casting machine,the

combination of the mold wheel, the mold wheel slide, and a universal joint between I the wheel and slide.

6. In a typographical machine comprising casting mechanism, the combination of a slotted mold, and a llne of matrices to engage therewith for al-inement, one of said elements being loosely mounted so that it may be rocked relativeiy' to the other during the. al ining action in a plane parallel or sub st'antially so with the face of the mold. by the said engagement of. the matrix. line with a the mold.

7. In a typographicalmachinecomprising casting mechanism, the combination of a mold carrier, a line of matrices to engage therewrths for alinement, the sand; carrier being mounted so that at the time of v alinement it may be rocked in its own plane relatively to the matrix line by the said en-' gagement of the matrix line with the carrier. In witness whereof I have hereunto set my hand intlre presence of two) witnesses; v HEINRICH. DEG'ENER.
