Also,"the usual duplex rail8 isreplaced by a rail 8 which extendsto a greater height than the rail 8 heretofore used, the rail 8a being grooved at its rear edge to form a rail 8b which is at such aV suficiently high elevation to support the matrices of the form shown in Fig.` 2 at the extra high alignment level by the resting of the lower forward lugs or ears E of such matrices 'upontherail 8", as shown by the dotted lines inFig. 4. The channel in the first elevatorbetween the front and rear aws thereof is extended upwardly to a greater' height than heretofore in orderto enable thematricesof the form shown in Fig. 2 to occupy the extra high alignment level, as is shown by dotted lines in Fig. 4. --The lower edge of the rail 8a and the rail 12 on the face of the mold body form aligning surfaces for the lower lugs or ears of the matrices when positioned at the lower casting level as shown by the full lines in Fig. 4. Y The 'present invention not only enables typographicaljmachines of thev general kclass hereinbefore referred toto use Ymatrices of the special form shown in Fig. 2 bearing type forming characters of greater point-size than has lvheretoforebeen possible with the usual two-letter matrices as shown in Fig. 1, but

it also enables'such machines to'use' two-letter Y matrices of the usual form shown inFig. '1,

with equal facility. fTo accomplishd this, the

rail 8a is formed at-its rear face notonly with the rail 8b to "cooperate with the lower forward lugs or ears of the special matrices as shown in Fig; 2 occupying the 'extraf high alignment level but it is'groovedlongitudinally or otherwise formed at its rear edgeto providea. second rail 9a'below the rail 8b, this rail 9et being located at the proper height to engage the lower forward lugs or ears of matrices of the usual form as 'shown-in Fig. 1 and 4to support such matrices at their upper casting level and the rail 8? is formed aboveor opposite tothe supporting rail 9a -with an alignlevel. The lower rear lugsjor ears of matrices of the usual form `when aligned at their 'upper casting level Vare accommodated in 'the in;- creased spacej formed between v,thelower aligning rail 12 andthe valigning rail 1125011 the face of the mold body; It will therefore be observed that the improved lduplex railv 8? embodies double aligning rails, that is,.the aligning rail Vformed by its lower edge for the lower forward lugs or earsEV ofthe matrices when positioned at the lower casting Y level and the aligning rail 9". which cooperates with said lugs or-'earsof matrices of the usual Aform shown in Fig. 1 when positioned atthe usual upper casting level. y It will be understood that in the improvedjconstruction form of two-letter matrices as shown in Fig.

1 and the special two-letter matrices as shown in Fig. 2 are laligned at the same lower casting level, but the two-letter matrices of the usual form as shown in Fig. 1 are aligned at i their upper casting level by the aligning rail 9b while the special form ofvmatrix shown in Fig. 2 is yaligned'at its upper casting level by the aligning surface formedf by the lower edge of the aligning bar 7a, as indicated by the dotted. linesin Fig. 4,'this` extra high alignment of the special matrix conforming with the location of the lower character C4 in a lower position on the matrix than heretofore, as has been hereinbefore described. It will be understood that the double'duplex rail 8a is movably mounted in the front jaw of the first, elevator so that it may be retracted to bring all of the matrices in the elevator to common alignment 4preparatory to the removal of the matrix line from the elevator,

substantially as shown. in Patent No.

in shown, such means is movable or capable of b'eing set so that it .will bring the special matrices to theextra high alignment level when set for such Vmatrices, but when it is set for the use of the usual form of two-letter matrices it will permit such matrices to pass into the aligning means or first elevator without affecting them. Preferably and as shown in the present instance,such means comprises a rail l'which is pivoted at 14 in a recess 15 formed in the rear-side of the front wall of theusual delivery channel 16 through which the matrices passgfromthe assembling eleva- `tor to the first elevator. This delivery chan- Ynel'is preferably formed as Vusual with rails 17 on whichthe upper lugsor' ears E of the 'matrices assembled at the lower level will rest and over which they will travel, thus supporting such matrices during their travel through the delivery channel* and this channel is also preferably provided with lrails 18 von which the lower lugsvor ears E of matrices ofthe usual form shown in Fig. 1 and yassembled at' their upper casting level may rest and over'which they may travel during the'movement of the matrix line Vthrough the delivery channel, it being understoodl that the'two-letter matrices are commonly assembled at their upper and lowerlevels,accord- .ingto the characterthereon from which the -cast isto be made, by the useof an assembling elevator .such for example as thatshown and describedin Letters Patent 1,149,7 68, granted Aug. 10, 1915,to T. S. Homans.

The-rail lprovided in. the delivery channel operates, when properly set,to raise the special form of matrices as shown in Fig. 2, V

port the lower lugs or ears on the front edgesA of the matrices of special form and to raise such matrices from the usual upper level at which they were assembled up to the extra high aligning level during the passage of such matrices through the delivery channel or into the rst elevator. The pivot 14 of the bar 13 is located at that end of the delivery channel which is adjacent to the first velevator and the matrix supporting rail 19Awill remain in substantially constantalignment with the matrix supporting rail 8b of the rail Sa in the first elevator, but the opposite free end of the bar 13, which is at the entrance or matrix receiving end of the'delivery channel, may be swung downwardly7 so that the rail 19 will receive the lower forward lugs on the special matrices assembled at the usual upper level in the usual assembling elevator, and as these matrices are conveyed through the delivery channel by the usual delivery slide, the special matrices assembled at the higher level will be lifted as they traverse the rail 19 or move toward the left on said rail inclined as shown in Fig. 8 so that they will be raised from the rails 18 anddelivered on to the supporting rail 8b in the first elevator, such matrices then occupying the extra high alignment level represented by the dotted lines'in Fig. 4. On the other hand, when the rail 13 is swung upwardly about its pivot 14 so that its rail 19 is parallel to and above the adjacent rail 18 in the deliveryslide, the rail 13 will have no effect upon two-letter matrices of the usual form assembled at their higher level while passing through'the delivery slide. Any suitable means may be Vemployed for moving or setting the controlling bar 13 either into or out of its operative position, a screw QOvbeing shown lin the present instance for thispurpose, its stem extending through a vertically elongated slot 21 formed in the front wall of the delivery channel and its rear end being threaded into the rail 13,

- the Jiront end of the screw having'a knob or head thereon which provides a handle by which the rail Vmay be lifted and lowered, and rotation of the screw in theappropriate direction will clampV the rail 13 in either of its two positions. Y

rfhe present invention also enables single letter matrices having much larger point size characters'to be used in machines of this class than has heretofore been possible.

The present invention enables line casting machines of the class now general use to use matrices of much larger point sizes than has heretofore been possible, by providing the machine with suitable matrix carrying jaws for the-larger character matrices that will also align the usual two-letter matrices, without the necessityof exchanging any ofthe regular parts of the machine, and the usual two-letter matrices;v and the larger character j matrices may be usedin separate lines or they may be mixed or assembled in the same line, 1f such 1s desired. Tousethe larger character matrices, it is only necessary to bring the magazine carrying Ysuch matrices into operativeV position 'in the machine, these matrices being'assembled and presented for casting by the usual operation of the machine,

although in assembling two-letter 'matrices` bearing the largercharacters for casting at the higher casting level, the controlling rail in the delivery channel is set in position to lift these matrices up to the eXtra high alignment level in the matrix retaining jaws of the first elevator. Y
