TYPOGRAPHICAL MACHINE.

Application filed February 27, 1920.

T 0 all whom it may concern Be it known that I, HANs PETERSEN, a citizen ofthe United States, .and a resident of Davenport,- in the county of Scott and State of Iowa, have inventedcertain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in typographical machines, and more especially has to do with the improved manner of and means provided for alining the matrices against the face of the mold during the casting of the line therefrom.

A great majority of line casting machines now in use employ what is known in the trade as two-letter matrices. These matrices are provided with two depressed characters in one of their faces,gsaid characters being spaced a certain distance apart. The matrix assembling devices are provided with two assembling rails, on either one or both of which the matrices'areadap'ted to be assembled before being advanced to casting position. If the assembled matrices are carried e to the casting position in front of the mold on the lower level, the result will be that as the mold advances toward the matrices, the lower alining grooveon the facegof the mold will coeperate with thelowerilugs of the matrices and alinethe upper characters against the faceof the mold opposite the mold cavity, and the line W111 be cast.

from-the upper series of characterson the matrices; On the contrary, if the line of matrices is presented in front of the mold assembled'on the upper rails, they will be engaged by the upper alining slot or groove in the mold and the cast will be made from the lower series of characters. 1

On practically all of the machines now in use two-letter matrices are employed in whichthe two charactersare spaced'such a distance apart that a font'of type larger than what is commonly known as 14: point, cannot be accommodated'on the matrix in the lower level. As all two-letter characters must necessarily be of the same height as they occur on the same matrix, this, for all practical purposes limits both of the characters to a size'not exceeding 14; points in height.

The objectof the present inventionis to Specification of Letters Patent. Patented July 26', 1921.

Serial No. 361,880.

to permit the casting of a larger slug than has heretofore been possible with the present standard construction ofthe essential parts of the mold, and from the present standard form of matrix. 4

The invention comprehends the use of twoletter matrices and cooperating two-letter mold of standard form, said matrices having characters larger in size than that of the characters on 14: point font of type, say, for example, 24 point height, and which may be used with the so-called 14: point two-letter matrices in the same machine havingelevator'mechanism of general standard. form.

The present application is to be considered as a continuation of my application, Serial No. 250,728, filed August 20, 1918, in so far as the subject matter is common to both cases.

The invention, with other objects and advantages thereof, and the particular constructions, combinations and arrangement of parts comprising the same, will be understood from the following detailed description, when considered in connection with the accompanying drawings forming part hereof and illustrating one embodiment vention.

In the drawingsa- Figure 1 is a side elevation of a mold carrying Wheel equipped with a series of molds in accordance with the present invention. Fig. 2 is a transverse section on the line 22 of Fig. 1 through the upper mold on the wheel showing in side elevation at the left of the mold structure'matrices adapted to cooperate therewith.

Fig. 3 is a'transverse section through another mold on the wheel showing to one side thereof in side elevation two-letter matrices having characters of largersize and adapted to cooperate with the same. 1

Fig. 4 is a front'elevation of an elevator body. Fig. 5 is an end view of the elevator body.

of the in- Fig. 6 is a transverse section on the line 66 of Fig. 4.

Fig. 7 is a detail side elevation of one of the matrices adapted to cooperate with the mold A; and

Fig. 8 is a detail side elevation of one of the matrices adapted to cooperate with the mold B.

Referring to a detailed description of the drawings, wherein like reference characters designate corresponding parts throughout the several views, 1 designates the mold wheel having a two-letter matrix mold A consisting of the body part 2 and cap 3, the mold cap having a forwardly projecting part 3. The body part 2 of the mold has upper and lower alining grooves 4 and 5, and 6 designates two-letter matrices, all as customarily employed in the usual form of line casting machine.

In accordance with the present invention, on the mold wheel 1 is mounted another mold B comprising a body 7 and a cap 8, the latter having a forwardly projecting portion 8. The mold B may be brought to casting position at will, and is adapted for use in cooperation with two-letter matrices 9, which bear characters of greater height and spaced a different distance apart than the characters on the matrices6 that are used with the mold A, said mold B being provided with upper and lower alinement grooves 10, 11. It will be noted that the alinement points for the upper character on both sets of matrices 6 and 9 are in the same relative position, but that in the case of the matrices 9, the charactersextend a greater distance in both directions from this common point than they do in the matrices 6.

12 designates the front elevator jaw having the stationary rail or shoulder 13 for supporting the matrices at their lower level, 14 the back elevator jaw, and 15 the spacingblock for the jaws. The moldsA and B, the essential parts of both of which, as shown,,are of the standard construction, are adapted to cooperate with the elevator jaws 12, 14 in the usual manner, the forwardly extending portions 3' and 8" of the respective molds extending beneath the lower end of the back elevator jaw 14 in the casting oper-l ation. In Fig. 2 of the drawings, the mold A is shown opened to its fullest extent of 14 points, which is the maximum size of the character and slug now cast with the tandard typographical machine from the normal alinement level of the standard matrix.

. In accordance with the teachings of'the present invention, the construction of the back elevator jaw 14 is changed as shown, (see especially Figs. 5' and 6 of the drawings) the usual alinement rail being omitted and the lower end 14 ofjthe aw terminating on the plane of the bottom face of the upper lugs of the matrix when in its lower level, provision thus being made for the adjustment of the mold cap 8 vertically a greater distance away from the mold body 7 and the opening of the mold to a greater extent. For this purpose the forwardly projecting portion 8 of the cap 8 is also reduced in size to the minimum practical thickness. I

A vital characteristic of the invention resides in providing the mold B with its upper alinement groove 10 of greater width than the correspondin alining groove 4; in the other mold A. This additional height is added at the under side of the groove and the action when the cast takes place is as follows: When it is desired to make a cast from the matrices 9 carrying the larger characters, the mold wheel 1 is given a half turn and the mold B is brought into casting position. As the line of matrices advances to casting position, they are first permitted to descend to a point a little be low the final casting position. The mold is then brought forward and engages the lower lugs of the matrices, the line of matrices being then raised by a flexible pressure mechanism (not shown) to a contact with the lower edge of the alinement groove 11. In the case of the set of matrices 9 carrying in their auxiliary position the larger characters, the flexible pressure would resultin the line of matrices rising a greater distance until they contact with the lower edge of the alinement groove in the mold, thus exposing the character to the mold slot at at a different level than is the case when the matrices 6 are presented to the mold A.

' It will be observed that this method of handling the matrices contemplates casting from the matrices 6 on both levels mixed in the same line, but from only one of the levels at. the same time' in the case of the set of matrices 9. If only one levelof the larger matrices. 9 is presented to the mold B at the same time, the usual non-adjustable supporting means (commonly knownin the" trade as elevator jaws) may be employed. If itis desired to mix the two faces carried by the matrices bearing the larger characters in the same line, it will be necessary to employ an adjustable variable matrix supporting device to present the matrix at levels corresonding tothe distance which the two c aracters are spaced apart on the matrix.- The means for this purpose, illus trated in the drawings, comprises the following parts: Instead of the usual single two-letter rail, two separate rails 15, 16 are employed, the rail 15 at its entrance end being provided with the tapered part 15 The rails 15, 16, are operated respectively by air -of levers 16, 17, said levers being hel in their normal positions for supporting the matrices by springs 18. A pair of of actionwlien desired.

v When-casting from the -matrices 6, not exceeding"substantially l point in size, the

matrices are supported in their lower or normal position J by the upper ears on the stationary shoulder or rail 13, and in their upper or auxiliary position by the 'rail 16. Wlien it is desired to make a cast from the matrices carrying sizes larger than 14 point,

and so cooperate with the mold B, which is fletter i atrices to-be alinedat two or more constructed to provide for th the matrices at threelevels. U

I" V WVhile Ihave illustrated in the drawings a specific embodiment of, the invention, it will of course be understood that changes and variations in the particular construction shown, and the carrying out of the-invention in. other forms as will appeal to those skilled in the art and falling within the scope of the appended claims, may be practised Without departing from the spirit of the invention.
