fo @ZZ whom, t 17mg concern.:

Be it known that we, JACQUES MAYnR and CHRISTIAN ALBRECHT, citizens of the United States of America, residing at Berlin, in the Empire of Germany, have invented a new and useful Type-Mold for Type-Casting Machines, of which the following is a specification.

Our invention relates to a type-mold to be used in type-casting' machines of any known kind and by which it is rendered possible to cast a plurality of types, log'otypes, or wordtypes at a time, whereby the production thereof is in proportion increased. rlhe new typemold can also be used in place of the linotypemold in linotype casting and composing machines, so that by this ty pe-mold it is rendered possible to produce at pleasure various typessuch as single types for letters, characters, signs, figures,&c. logotypes, ornament-types, justifying-types, and the like-which can be composed and employed for replacing cast linotypes, and thus correcting the composition formed of linotypes, the printing surfaces or characters of the said various types exactly resembling those in the cast linotypes. The proprietor of a linotype casting and composing' machine is also thereby enabled himself to make various types of the kind indicated above instead of ordering or procuring them elsewhere at a not inconsiderable cost and loss of time.

The new type-mold is provided with a plurality of parallel cross cells or cavities and may be secured on a convenient stationary part or a moving' part of any known typecasting machine, or it may be secured in place of the linotype-mold on a gear or mold wheel of any known linoty pe casting and composing machine. Then a plurality of matrices of the machine, suitably composed to a block, or a detachable matrix-block secured either on a swinging or moving part or on a stationary part of the machine, or a matrix-plate affixed on a stationary block can be applied to or pressed against the ends of the cavities of the mold on the one side and the liquid metal forced into 'the cavities from the melting-pot on the other side through the respective mouthpiece by the pump of the machine. The types having thus been cast in the cells or cavities of the mold, the block of matrices or the matrixblock is removed from the type-mold, or the latter is withdrawn from the matrix-plate or moved aside, or it is rotated with the gear or mold wheel, as the case may be. Also the melting-pot may be removed or turned back or remain stationary, according to the construction of the respective type-casting machine or linotype casting and composing machine. Then the feet of the types, logotypes, or wordtypes are trimmed in any known and approved manner, and afterward they are ejected.

i/Ve will now proceed to fully describe and explain our invention with reference to the accompanying drawings, in which-- Figure l is a plan of our type-mold and a block of matrices applied to the front of the same. Fig. 2 is an elevation of the typemold. Fig. 3 isa plan of the bottom part of the type-mold to show the several parallel cross cells or cavities. Fig. 4 is a cross-section through the line A B in'Figs. l and 2. Fig. 5 shows, on an enlarged scale, a section through a part of the mold on the line C D in Fig. 2, the printing-surfaces on the front in Fig. 2 being turned upward. Fig. 6 shows in elevation, on a reduced scale, a gear or mold wheel with a modified type-mold secured therein. Fig. 7 is partly a longitudinal section through the line EF in Fig. 6 and shows part of a melting-pot and the gear or mold wheel, both partly in section, and a matrixblock in section. Fig. 8 shows, on an enlarged scale, a section through part of the gear or mold wheel on the line G H in Fig. 6 and a plan of the bottom part of the type-mold. Fig. 9 is a plan of a matrix-block, and Fig. lO is a cross-section through the same on the line I K in Fig. 9.

Similar characters of reference refer to similar parts throughout the several views.

The mold for producing a plurality of types according to our invention is preferably made in two parts l and 2, as is shown at Figs. 1 to A, inclusive. The lower part l is provided with a plurality of partition-walls 3 3, so that a plurality of cells or cavities L L is thereby formed, in which the types, logotypes, wordtypes 5 5, and the like can be cast. The height of the cells is equal to the thickness of the types, and the width of' the several cells or cavities 4 4 will have to vary according to the breadth of the single types, logotypes, Word-types, ornament-types, justifying-ty pes, and the like to be produced. The partitionwalls 3 3 are preferably provided on the rear ends with projections or noses 6 6, Fig. the purpose of which will be explained later on.

When assuming this type-mold to be intended for a type-casting machine of any known construction, it is secured either on a stationary part or on a moving part of the ma- IOO IIO

chine, as the case may bc--for example, by

means of screws passing' through thel holes 7 7. Then a block composed of conveniently-selected matrices 8 8 and secured between two vise-jaws 9 9 is placed against the'front of the mold if the latter is stationary, or the typemold is pressed against the block of matrices 8 8 if this block is stationary, as is shown at Figs. 1 and 4, so as to close the cavities 4 4 of the mold on the one side. Of course the recessed characters 10 on the several matrices 8 8 require to be placed exactly in the center lines of the cells or cavities 4 4 for single types or in the center lines of the respective types to be cast in groups in the cells or cavities. Ne have not shown fully the vise-jaws 9 9, as their construction is immaterial and well known. The vise-jaws 9 9 are arranged on a known swinging or moving part of the machine in case the type-mold is stationary. Thereby the block of matrices can be easily turned on and off. Also it can be replaced by another one. There so preferred, a solid matrix-block, as shown in Figs. 9 and 10, may be employed in place of the several combined matrices 8 8. This matrixblock is made up of a series of matrix-faces of the outline shown in Fig. 10 and is used in the mold as a substitute for a series of matrices. In case the type-mold is secured on a moving' part of the machine the two vise-jaws 9 9 are arranged on a stationary part of the machine, and between them the block of matrices 8 8 or the solid matrix-block is secured, or it may be preferable to replace either block by a matrix-plate, which can be detachably secured on the said stationary part in any known and approved manner. Then the matrix -plate can easily be replaced by another one, if so required.

The device described so far is operated in the following manner: When during the operation of the machine the block of matrices 8 8 or the matrix-block is applied to the front of the tyi'ie-n'iold or the latter, if mounted on amoving part of the machine, is applied or pressed with its front against the block of matrices or the matrix-block and when the melting-pot is brought into its casting position by turning it upward or moving it forward, as the case may be, so that its mouthpiece 11 bears Aagainst the rear side of the type-mold, Fig. 4, then by the pump the liquid metal is forced from the melting-pot, through the mouthpiece 11, into the cavities 4 4 of the type-mold to till them out. The metal in these cavities having becometorpid, the type-mold is again released from the matrices 8 8 or the matrixblock and the mouthpiece 11 by reversing the respective motions described and the feet of the cast type-bars 5 5 are in the usual manner trimmed by a knife 12, Fig. 5. This knife 12 is either stationary, if the typemold is moved aside bythe respective machine part, or movable, if the type-mold is stationary, in which case, of course, the mouthpiece will have to be moved off so much as to leave suieient room for the trimming'- knife. Afterward the linished types 5 5 are removed from the type-mold. The projections or noses 6 6 on the rear ends of the partition-walls 3 3 in the mold part 1 facilitate the trimming of the feet of the types, as they prevent the cast types, logotypes, or word-types from being drawn out of the cells by the knife 12 during the trimming, whereby otherwise they might get a varying length instead of the uniform length, which is absolutelynecessary for obtaining excellent impressions or prints.

When applying the new type-mold to a linotype casting and composing machine, it is suitably modified, as is, for example, shown at Figs. 6 to 8. To illustrate the use of the type-mold, we have shown the cells or cavities 17 17 to be different in width in accordance with the breadth of the single types, logotypes, word-types, ornament-types, and the like tol be produced. This mold is secured in place of the linotype-mold in the opening 13 of the rotating gear or mold wheel 14 in the usual mannerfor example, by means of setscrews 15 15 and screws 16 16. Then the gear-wheel 14 occupies the position shown at Fig. 6, the rear ends of the cells or cavities 17 17 in the mold 18 19 will be exactly opposite to the horizontal opening 2O of the mouthpiece 21 on the melting-pot 22, (see Fig. 7,) when the latter is turned upward, as is the casein most linotype-casting machines. A block of matrices or a matrix-block 23, secured between two vise-jaws on a known swinging or moving part of the machine, can be applied to the front of the mold. This device is operated as follows: Vhen the gear-wheel 14 occupies the casting position (shown at Fig. 6) and the matrices or the matrix-block 23, as the case may be, are or is pressed against the front of the mold 18 19. Fig. 7, by the respective known machine part, then the known pump will force the liquid metal out of the melting-pot i2, through the opening 20 of the mouthpiece 21, into the cavities 17 17 `of the mold to till them out. The swinging or moving machine part carrying the matrices or matrix-block 23 having been moved off, the gear-wheel 14 is then in the usual manner rotated through threefourths of a revolution, during which the feet of the types are trimmed by the known knife (similar to 12 in Fig. 5) on the rear side of the gear-wheel. When the latter assumes the ejecting position, the finished types are ejected in a manner to be described in another United States patent.

The whole device can be varied without deviating from the spirit of our invention.

hat we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination with a type-mold hav- IOO IIO

ing a plurality of cross-cavities of the size of the several types, logotypes or word-types to be produced, of means adapted to close the cross-cavities of said type-mold on the one side, and means for forcing liquid metal into the cross-cavities of said type-mold from the other side, said type-mold having on the rear end of each cavity a projection or nose to prevent the cast types from being drawn out of the cavities by the trimming-knife.

2. The combination with a type-mold having a plurality of cross-cavities of the size of the several types, logotypes or word-types to be produced, of a matrix-block adapted to close the cross-cavities of said type-mold on the one side, and means for forcing liquid metal into the cross-cavities of said type-mold from the other side, said type-mold having on the rear end of each cavity a projection or nose to prevent the cast types from being drawn out of the cavities by the trimmingknife.
