To all wit-0111, itjmaz'y concern;

Be it known that'I, CARL MUEHLEISEN,-Of

Baltimore, State of Maryland, have. invented a new and useful Improvement iii Linotypelarly to linotype-machines of the general v4l-.36,531 and 436,532, although it isjal'so applicharacter represented in Letters Patent of the United Statesissued toOttmar Morgenthaler onflthe lfithof September, 1890, Nos.

cable in other machines of analogous construction. v I a V In a linotype as ordinarily constructed the operator manipulating the keyboard causes.

the matrices and spaces to be delivered from the magazines and composed or assembled in lines in a receiver, commonly known as'an assembler. When the composition of a line is completed, this assembler is lifted and the matrix-line is transferred at once through intermediate mechanism to the face of the mold for use. It frequently happens, however, that the. composition of a line is completed before the casting mechanism is in po- "sition to receive it, and in such event there is a loss of time on the part of the operator, who is compelled to wait until the line in the assembler can be disposed of preparatory to bc-V ginning the composition of the next line of matrices.

The object of the present invention is to' avoid this loss of time and so contruct the posed of at once, and the composing opera tion continued, although the parts may not be at the moment in-position to permit the transfer of the completed line to the mold.

.To this end myinvention consists in a provisional means whereby acomposed' line may be instantly transferred and held in abeyance until thecasting mechanism is ready to receive it. r

The details may be varied in form and arrangement in many 'ways which will suggest themselves to the skilled mechanic after a consideration of this specification and the accompanying drawings without changing the mode of action or departing from the limits of my invention.

The device consists, essentially, of two blades which areintroduced at the right hand of the matrix-line as soon as composition is completed, one blade then shifting to the left and carrying the completed line into the devices for receiving and transferring it, while the other blade remains to keep the new line in course of composition in compact order,

the two blades being finallywithdrawn preparatory to use in due time behind the secondlineJ- i V I have limited the drawings to myimproved devices and to such parts of the linotype-machineasare necessary to ah understanding of the improvements. In all other respects the machine maybe of ordinary construction.

Figure l is a front elevation showing the 'eratingblade.

Referring to Figs. 1 and 2, A represents an assembling belt of a linotype -machine on which the matrices D are received, one at a time, from the magazine and from which they pass downward over the supportin -rails B to a position in front of the rotary star-wheel G, which serves to crowd them forward, one after another, into the assembler-block E, in which they are composed or assembled in line, side by side, in the usual manner, together with suitable spaces, until the line contains all the characters and spaces required in one line of print, so that it is ready for transference to themold or casting mechanism preparatory to the composition of the next line in like manner. The foregoingoperation is essentially the same as in the ordinary'machine. The construction shown, however,

difiers from that of the ordinary machine in that the grooved or channeled assembler E in the present instance is stationary, being attached to or made integral with the machine,

whereas in the ordinary machine this assembler ismovable vertically in order that it may be lifted to present the composed line to the transfer devices above. To effect this transfer of the line, I now provide the receivingelevator F, arranged adjacent to the assembler E and mounted to slide vertically. It is grooved or channeled in the top to register with the assembler, so that the composed line of matrices when completed may be shifted horizontally to the left out of the assembler E into the elevator F, which, rising in due time, presents the composed line between the fingers G and G of the horizontallysliding transfer-carriage. This carriage is practically identical with that used in the or dinary linotype, except that its fingers stand farther to the 'left in position to receive between them the matrix-line presented by the elevator. This carriage may be constructed and operated in all respects in the same manner as the ordinary carriage of the Mergenthaler machine to transfer theelevated line to the left into the usual first elevator, by which it is presented to the mold, and thereafter to the distributing devices. The constructiouand operation of these parts form no part of my invention.

During the composition of the matrix-line in the assembler E the advance of the line is resisted and the matrices held in close order by the upright finger h, which is urged constantly to the right by spring 7L, asnsual, the line being composed and confined for the time being between the star-wheel G and the fin ger h. This finger instead of being made solid, as usual, is made of U form, as plainly shown in Fig. 2, so that the line-separating fingers may .pass thereth rough, as hereinafter explained. After the composition of the line is completed in the assembler E it must be transferred bodily to the left into the elevator F, so that the composition of the next line may proceed in the assembler E. In order to effect this transfer of the completed line and for the time being to hold the matrices of the next line in compact order, I provide the two vertical bladesl and K, which receive vertical and lateral motions through mechanism hereinafter described in detail. In order that the action of these blades may be clearly understood, I will first describe their several movements and thereafter describe the mechanism for effecting these movements. During the composition of the line the two blades stand together, with their pointed ends below the star-wheel and to the right of the line, as shown in Fig. 3. \Vhen the line is completed and ready for transfer, the blades rise at the right of the line, as shown in Fig. 4, the line being at this time confined between the blade I and the finger h of the assembler-slide. The two blades being now free to advance to the left, the composition of the next line may proceed, its foremost matrix being supported by and against the blade K. During this action both lines will advance to the left and the two blades will be carried forward between them. At the proper time, as soon as the transfer of the first line to the elevator is demanded, the blade I separates from its companion and moves to the left, as .shown in Fig. 6, carrying the completed line before it and. against the yielding finger it into the elevator F, which then rises, carrying the line of matrices upward between the fingers G and G of the shifter-carriage, which, moving to the left, carry the line forward through the intermediate channel toward the casting mechanism, as usual. When the line is thus lifted clear of the assembler-finger h, the latter un der the infinenceof spring h returns to the right until it bears against tle left end of the new line in course of composition, as shown in Fig. 7. It will be remembered that the finger is made of new form, so that in returning to its normal position it may pass freely over the upper ends of the blades I and K. After the line has been lifted the blades I and K arelowered, closed together, and re turned to the right to their original position below the star-wheel in order that they may transfer the second line in the same manner that the first was transferred. It will be observed that the foregoing action of the blades admits of the composition being carried on uninterruptedly and that there is no necessity for the operator to await the disposal of the first line before beginning the second.

' I will now describe the mechanism by which the blades are actuated.

The right-hand blade K is made of the form shown in Figs. 12 and 13, with its foot adapted to slide in the horizontally-grooved barL, (shown in cross-section in Fig. 2,) which is mounted on the upper end of the supporting rod Z, arranged to slide upward and downward in guides L on the main frame. The left-hand blade I is made of the form shown in Figs. 14, 15, and 16, with an'extended end piece, which is also arranged to slide on the supporting-bar L, but preferably in a groove distinct from that containing the other blade, as shown. It will be observed that the two blades are free to slide to the right and left on the arm L, and that the latter, being free to rise and fall, serves to raise and lower the blades.

The vertical movement of the blades is effected as follows: The vertical guide-rod Z is connected by link Z to a lever 1 pivoted in the main frame and urged upward by a spring F, the effect of which is to lift the blades to and maintain them in their highest position whenever the lever is released. The depression of the blades is effected by extending the lever Z beyond its fulcrum Z and providing its upper end (see Figs. 1 and 10) with a roller Z acted upon by a cam Z on the horizontal shaft M, which carries a driving-gear in, engaged, as shown inFigs. 1 and 2, by a pinion m the shaft of which is provided with a and the blade I to the right, holdingthe ceases ,v v a grooved pulley m which may be driven by a belt from a pulley applied to any one of the constantly-running shafts of the linotype-maother parts are at "rest. wheel there is a circular series of studs m,

this finger-key at the proper time releases the lever and sets the parts in action, as follows: I

The gear-wheel m, being constantly rotated by its driving-pinion, is mounted loosely on theshaft M, so that it'turns freely, while the On=the face of the one or another of which may be engaged by the clutch-finger-m pivoted to the hub m fixed'on the shaft and acted upon by a spring on", which tends to. throw the finger m into' engagement with one of the studs, which, sweeping the finger beforeit, will effect the rotation of the shaft and cams. .In order to disengage the parts at the end of each revolution, the oblique tripping-lip m isfixedto the lower rear end of the lever Z so that when the cl utch-arm mTapproaches'its original position its-lower end will ride against the oblique lip, as shown in Fig. 2, so as to be drawn back thereby out of engagement with the stud,

the lever being at this time held down by the finger-key N. Now when this lever is released, as before mentioned, its forward end rises and its lower end falls out of engagement with the clutch-finger m as shown in Fig. 10, allowing the latter to again engage the driving-gear. It will of course be understood that when the forwardend of the lever is depressed by the action of the cam it is an tomatically engaged and held down by the finger-lever N, this locking of the lever keeping the blades I and K down and also keeping the rear end of the lever in position to hold the clutch-finger out of action, as shown in Figs. 1 and 2. I

The lateral movement of the bladesvto effect the shifting and separation of the matrix lines is effected as follows: The left-hand blade I has an ear amounted to slide on a vertical rod 2 arranged to move horizontally on a guide-rod i fixed to the main frame. The slide '1? is connected by link i to the upper end of a lever-i pivoted to the main frame at. i and having its lower end connected by link i to a second lever i which is pivoted to the main frame at Z and provided at its lower end with a roller 2', acted upon by a cam i fixed on the before-mentioned shaft M. A tension-spring 1' connects the,upper end of lever 11 with the main frame, a

as shown in Fig. 1, and serves through the intermediate parts to urge the vertical rod 1" blade normally in the position shown in Figs.

1 and 3. The blade I serves to carry the blade K before it to they right, and thesecond matrix-line as it increases in length forces the blade Kbefore it m the left, there being at one stage of the operations a considerable distance between the two blades, as shown in Figs. 6,7, and 8. The frictional engagement between the blade K and the supporting-bar L is such that the blade ofiers a suitable resistance to the advance of the second line during the absence of the main resistant h, which, it will be remembered, is moved temporarily to the left in. advance of the first matrix-line preparatory to the transfer of the latter. After the first matrix-line has been lifted clear of the resistant h the latter returns to its position at the end of the second line in course of composition, as shown in Fig.

7, and itis after this action that the blades are drawn down andrestored to their position at the right of the line. The resistant h is carried, it will be remembered, by the assembler slide or'bar H, whiehis provided with the usual stop-shoulder 77. (See Fig. 1.) This stop, used to limit the advance of the assembler and thus determine the length of the line which can be composed, instead of being arranged to encounter the usual stop is now arranged to abut against one end 'of a leverO, which I provide for the purpose. This leveris pivoted to themain frame F at 0 and connected at its opposite end by rod 0 to the fin ger-key lever N, so that when this lever is released to start the mechanism for shifting the blades it at the same time moves the stop-lever 0, so that the assembler-slide may continue its movement to the left as demanded by theshiftiug of the line.

' I believe myself to be the first to provide mechanism for assembling the matrices in a continuing line and dividing thisline by two codperatin g fingers entering at the rear of the line into groups suitable for use in producing the successive linotypes without interrupting the course of composition. 7

It will be evident to the skilled mechanic that the details of construction maybe greatly modified without departing from the principle of operation or the limits of my invention.

Having thus described my invention, what I claim is 1. In a linotype-machine, a matrix composing or assembling mechanism, an elevator for the composed lines, and a transfer mechanism comprising means to shift a composed line from the assembler to the elevator and means to sustain the following matrices in the assembler.

2. In a linotype-maehine, a mechanism to compose the matrices in a continuing line, in combination with two blades adapted to enter at the end of the line and separate lengthwise thereof, whereby the matrices for one linotype may be separated from those following.

3. In a linotype-machine, mechanism for composing the matrices in continuing lines, in combination with two blades or separators shifting them into the elevator.

5. In a linotype-machine, the combination of the composing mechanism, including the resisting-finger, the elevator, the two blades or fingers, and mechanism to advance said blades into and Withdraw them from the line and to move them laterally, substantially as shown and described.

6. In a linotype-machine and in combination with assembling mechanism, the two blades, I and K, the bar on which they are sustained and arranged to move laterally, a cam and connections to raise and lower said bar, and a cam and connections to move blade I to the right and left.

7. In a linotype-maehine, a com posing mechanism in combination with a yielding resist= ant for the front end ofthe line, a second resistant or blade to enter the line in rear of the first, one being formed and arranged to pass the other without collision in the absence of intervening matrices.

In testimony whereof I hereunto set my hand, this 1st day of May, 1899, in the presence of two attesting witnesses.
