TYPOGRAPHICAL COMPOSING-MACHINE.

Specification of Letters Patent.

Application filed April 15, 1912.

Patented Dec. 2, 1913.

Serial No. 690,853.

To all whom it may concern:

Be it known that I, Gnonon P.1(1NGSIBIJI1Y, a citizen of the United States, and a rcsident of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Typographical ComposingMachines, of which the following is a specification.

My invention relates to typographical composing machines, such as linotype ma chines of the general organization represented in Letters Patent of the United States, No. 436,582, to O. lvlergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print, and .thcn assembled in line together with spacers, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type or characters thereon, and the matrices thereafter elevated and returned through a distributing mechanism to the magazine from which they started.

More particularly it relates to the matrix escapement actuating devices, as shown for instance in the Letters Patent to Morgenthaler, No. 658,740, wherein a plurality of such devices is illustrated and also mechanism whereby they are alternately actuated from a single operating means.

The general object of such construction is to deliver continuously similar matrices from different channels containing them, automatically and without demanding the care or attention of the operator, the principal advantage being that the more frequently employed matrices, such for instance as those representing the letter e, may thus be continuously released without the danger of exhausting the supply, as might be the case were they stored only in a single channel. To this end, and in order to effect the automatic alternate operation of a plurality of escapements, I preferably employ a corresponding plurality of actuating reeds, and in connection therewith an actuating member formed with different portions adapted to engage the different reeds, and a single operating means for the said actuating member. In the specific form shown, this member is a wheel which is operated from the keyboard mechanism in the customary manner, and formed on opposite sides with projecting pins arranged to engage alternately with a corresponding pair of reeds.

Another feature of my invention is the provision of means whereby the actuating member is first brought into position to ac tuate a reed, and by a subsequent movement is freed therefrom. In the specific form illustrated, the operating cam is formed with a cylindrical cam surface, which engages the actuating pin with the reed and permits it to dwell in this relation until the escapement has had time to act, after which a riser on the cam operates to disengage it therefrom.

In the accompanying drawin I have shown my improvement by way of example and in preferred form, as applied to the specific kind of machine already mentioned, but obviously many changes and variations may be made therein, and similarly it may be used in connection with other typographical composing machines, such as type-setters, type-casters, and the like, without departure from its spirit; and generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment except in so far as such limitations are specified in the claims.

Referring to the drawing: Figure 1. is a detached perspective view of the escapemcnt actuating devices, having my invention applied thereto; Fig. 2 is an enlarged transverse sectional view; and Fig. 3 is a front detail view.

The matrices X are as usual stored in channels of the magazine A, each of which channels is provided with an cscapement A a pair of such escapements being illustrated in Fig. 1. A correslmnding pair of reeds B and B serve to actuate the escapements, they being moved in one direction by springs ll and, in the opposite direction by the ratchet wheel K. The wheel K is rotated step by step by the pawl J connected to the longitudinally movable bar H, which is reciprocated in the well known manner by the pivoted arm I) carrying the cam I), and which cam is adapted to be brought into operative engagement with the constantly rotated roll C by the finger'key G, slide G and tripping pawl F. Except as otherwise indicated, the several parts are or may be of the ordinary constructnm.

'llurning now to my improvement, it will be noted that the reeds B and B are located at opposite sides of the ratchet wheel K, and that the latter is formed on one side with a series of pins L adapted to' engage and actuate the reed B, and at the opposite side with pins M to engage the reed 5 It will further be noted that the pins M and L are alternated or staggered with relation to each other, so that they are alternately brought into operative relation to the respective reeds. It therefore follows that the continued step-by-step rotation of the wheel K results in the alternate actuation of the es capements, and that matrices are thus alternately released from the corresponding magazine channels. In this manner the liability of exhaustion of any particular or frequently employed matrix may be obviated. Of course, the pins L and M may be arranged in alternating groups of two or more, if desired, the effect of such arrangement being the release of corresponding alternating groups of matrices fromthe respective magazine channels.

As is well known in the art, the actuation of the escapement A involves the necessity for a slight dwell, in order to permit the free escape of the delivered matrix and the passage of another to take its place, before the parts. return to normal position. As previously indicated, the reeds B and B are moved positively in one direction by the engagement therewith of pins L or M, respectively. In order to permit the necessary dwell referred to, the pin should remain in engagement with the reed for a definite period, and this is provided for by the formation on the cam E of the cylindrical cam surface E It is next necessary to move the pin out of engagement with the reed, and this I effect by providing the cam E with an additional or supplementary riser E, which, on engagement with theconstantly rotated roll C, and through the pivoted arm D, ba v H and pawl J, moves the ratchet wheel K to its final position and thus disengages the pin from the reed, and permits the spring B to return the reed, and consequently also the restoration of the escapement A to its normal position.

As previously stated, I have illustrated my invention by way of example and in preferred form, but obviously many modifications thereof will suggest themselves to those skilled in the art and still be comprised within its spirit.

Having thus described my invention, its construction and mode of operation, what I Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,-

claim and desire to secure by Letters Patent of the United States is as follows:

1. In a typographical composing machine, the combination of a pair of escapements for the type or matrices, a corresponding pair of reeds to actuate the said escapements, and a periodically operated single actuating means for the said reeds, the said actuating means being formed with different members to engage the different reeds and so located that the reeds are engaged alternately thereby.

2. In a typographical composing machine,

the combination of a pair of escapements for the type or matrices, a corresponding pair of reeds to actuate the said escapements, and aperiodically rotated member formed with projecting portions arranged in staggered relation so as to engage the reeds alternately.

3. In a typographical composing machine, the combination of a pair of escapements for the type or matrices, a corresponding pair of reeds to actuate the said escapements, and a periodically rotated wheel formed with portions projecting from its opposite sides to engage the reeds alternately.

4. In a typographical composing machine, the combination of a pair of escapements A a pair of actuating reeds B, B, and the periodically rotated wheel K formed with the oppositely located pins L and M to engage the reeds B andB respectively.

5. In a typographical composing machine, the escapement actuating mechanism comprising in combination, the reed, the wheel having an actuating portion to engage the reed, and an operating cam and suitable connections to rotate the wheel, the said cam being so formed as to bring the actuating portion into engagement with the reed, then to permit a dwell, and then to move the actuating portion out of engagement with the reed,

6. In a typographical composing machine, the escapement actuating mechanism comprising in combination, the reed B, the wheel K having the pin L, and means to rotate the wheel K, comprising the cam E having the cylindrical portion E and the riser E In testimony whereof I hereunto set my hand this 11th day of April, 1912, in the presence of two attesting witneses.
