LINOTYPE'MACHINE-f SPECIFICATION forming part of Letters Patent No. 685,036, dated October 22, 1901. A Application filed rm 19,1901. saameam. mamas To alZl whom it may concern."

Be it known that I, PHILIP T. DODGE, of Washington, District of Columbia, have invented a new and useful Improvementin Linotype-Machines, of which the following is a specification.

The object of my invention is to adapt a linotypeunachine to produce type matter in either of several faces at will.

To this end it consists in combining a series or font of matrices, each of which has two or more characters differing in style and separately usable, with means for sustaining the line of assembled matrices in a definite posi-' tion and means for adjusting the mold lengthwise of the matrices, so that it may be presented in position to cooperate with either style of matrices, as demanded.

Linotype-machines have been heretofore constructed with matrices bearing a plurality of characters, combined with means for setting the matrices in line ata higher or a lower level in order that one or another of the characters may be presented in operative relation to the mold, which was presented always at one and the same height. This adjustment of the matrices involved a modification of the machine in many respects and the employment of numerous parts which are rendered unnecessary by my construction.

Myinvention is applicable to the Mergenthaler linotype, the Rogers typograph, the Scudder monoline, and generally to all machines in which a mold is arranged to codperate with an assembled line of matrices, and it is to be understood that the details of construction may be varied at will to meet the peculiarities of the different machines withoutdepartin g from the limits of myinvention.

In the accompanying drawings I have represented only such parts as are necessary to an understanding of the invention.

Figure 1 is a vertical section through the casting mechanismof a linotype such as shown in application for- Letters Patent of the United States Serial No. 57,561, of the year 1901. Fig. 2 is a horizontal section on the line 22 of the preceding figure. Fig. 3 is a vertical section through the casting mechanism of a linotype-machine such as shown in application for Letters Patent of theUnited- 'States'Serial No. 47,992, of.1901 I section of the same on the line 4' 4 lookingiri the direction of the arrows. Fig.6 is a'vertical section through the mouth of the melt ing-pot.

Referring to Figs. 1 and A represents a line of matrices, each havingin one edge, as

shown, two matrices or characters, one above the other, intended for separate use. Bis a support or elevator by which these matrices are sustained always at the same level in front of the mold. G is the mold, having,as usual,

a slot or mold proper therethrough from front to back of the dimensions of the requiredslug or linotype. ,This mold is mountedin the present instance, to slide endwise in the top of a supporting-frame D, which swings on a horizontal shaft E at its lower end, this in order to permit the mold to swing to and from the mouth of the pot and the matrices. F represents the mouth of the melting-pot, which in the present instance is fixed in'position or, in other words, is without a forward and backward movement. The pot is intended to close tightly'against the back of the mold, which in turn closes tightly at its front against the alined matrices, as usual in this class ofmachines, so that the molten metal delivered into the mold and forming the slug or linotype therein will have raised type produced on its edge by thosecharacters of the matrices which are for the moment in line with the mold. If the mold alines with the upper characters in the matrices, the type If it alines will be of one form or design. v with the lower characters in the matrices, the type will be of adifferent design. In order to permit this change, the mouth of the mold 7' is of such form that it may be presented to codperate with either the upper or the lower characters, and the frame D, in which the ings or supports for the frame D, in which they are seated. B y the rotation of the shaft the eccentrics may be turned and caused to raise and lower the frame D and the mold therein. As a convenient means of turning the shaft and eccentrics I propose to form on one of the latter a worm-wheel H and to operate the same by means of a worm I, seated between hearings on the frame and carried by a spindle J, having a hand-wheel or other means for turning. When the eccentrics are turned to their uppermost position, as shown in Fig. 1, the mold will stand at a suitable elevation to cooperate with the upper characters in the matrices, and when the eccentrics are reversed or turned downward the mold will stand in a lower position to cooperate with the lower characters of the matrices.

The pot may remain stationary, in which case the orifices in its mouth will be widened vertically to such an extent that they will deliver metal to the mold in either of its positions,-

or the pot may be adjustable vertically in order; that small orifices in its mouth may aline with the mold in either position. The vertical adjustment may be eifeoted by means of SGlZr-SGIGVS K, located beneath the pot and seated in the frame or by any equivalent means.

Referring to Figs. 3'and 4, the matrices A, of: diiferent lengths, each havingtwo differentcharacters, are suspended on a series of fixed inclined guidesM, as in the well-known Rogers typograph. The selected matrices descend the converging guides until they reach their lower parallel ends, where they are assembled inline in front of the mold, asshown in Fig. 4 and as fully explained in application SerialNoA7,992, above referred to. Although the matricestare of'various lengths, their lower ends, each of which is provided with two or more characters or matricesproper, terminate at a common level, so that the'characters in the assembled matricesstand in two parallel lines, one above the other. The matrices are held in alinement and against longitudinal motion by a. fixed anvil T, having a rib which enters a-notch in the rear edges-.ofthe matrices. Themold C is in this case mounted on the upper end of a vibrating arm N, pivoted at O, so that the mold can swing after the casting peration into position to permit the ejection of theslug. The mold is in this case connected to the upper end of the carryingarm by two vertical guide-screwsl, each havingbeneath its head a spring Q, serving to pressthe mold downward. Between the mold and the upper end of the support N there is a sliding double-ended wedge-plate B. When in the position shown, it permits the mold to stand at its lower level, so that it will coopcrate with the lower characters in the matrices. If it is required to reproduce the up per; characters, it is only necessary to drive the wedge endwise, the eifectof which will i be to raise the mold to the level of the upper characters. In this case the melting-pot F may be fixed in height or adj ustable. vertically, as desired.

Instead of adjusting the entire pot vertically I may, if preferred, adjust only the mouth or portion which cooperates with the mold. One construction to this end is plainly shown at Fig. 5, in which the perforated mouthpiece F is seated in a. horizontal dovetail groove in the pot and secured by a key f. When the mold is used in the elevated posi tion, the key is driven beneath the mouthpiece, which is held at its highest level, as shown in the drawings. If the mouthpiece is to cooperate with the mold in the lower position of the latter, thekey is removed from beneath the mouthpiece and inserted above the same, the eifect being to lower the mouthpiece in relation to the body of the pot and the mold.

It will be observed that in each oft-he constructions herein shown the matrices are presented at a constant or fixedposition and that they remain in this position whether the upper or the lower characters are to be used, while the mold, on the other hand, is raised or lowered to cooperatewith the upper or lower characters, as demanded.

It will of course be understood that each matrix may have three or even four variant characters and that in such case the adjustjment of the moldwill be modified to correspond.

That I claim as myinvention is 1. In a linotype-machine and in combina:

tion with matrices, each having a plurality of characters, means for-sustaining the assembled matrices at a fixed level, a mold to cooperate therewith, and means foradjusting the mold to aline with the respective charac ters in the matrices.

2. In a linotype-machine, a series-of fixed guides M, a series of matrices pendent therefrom and each havingtwo or more characters :at different heights, a cooperating mold and means for adjusting the mold to aline' with the upper or the lower characters at will.

3. In a linotypemachine in combination with matrices each having a plurality of char- .acters at different heights, means for holding the assembled matrices in line, a 'codperating mold, means for presenting the mold in alinemen-t with the upper or the lower characters as required,and a codperatingpot with means for adjusting its mouth to cooperate. with the mold in the different positions ofthe latter.

at. In a linotype-machine, the combination ofa mold, a mold carrier swinging abouta center, and means for changing the distance between the mold-slot and said center.

In testimonywhereof I hereunto set my hand, this 5th day of June,190l, in the pres ence of two attesting witnesses.
