TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented June 3, i919.

Application led July 15, 1916. Serial No. 109,450.

To all whom t may concern:

Be it known that I, DAVID S. KENNEDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typographieal Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention has reference to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States to O. ldergenthaler, No. 436,532, wherein matrices representing the various characters to appear in print are stored in a channeled magazine and are released therefrom one at a time through the action of escapement dcvices controlled by finger keys. in these machines, it is common to store the more frequently used characters, such as the letter e, in two or more channels of the magazine, and to provide mechanism whereby a single finger key may effect their release from the different channels in alternation or succession. My present invention is directed to this same general result, and is intended to simplify the mechanism and to render it more certain in operation, as will be more fully pointed out in the detailed description to follow.

In the accompanying drawing, l have shown my invention merely in preferred form and by way of example and as applied to the particular style of machine mentioned, but obviously many variations and alterations may be made therein, and in its mode of application, which will still be comprised within its spirit. Thus it may be applied to other forms of escapement or matrix releasing devices and to other styles of machines, such as typesetters and the like. Generally speaking, l 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 l is a perspective view, partly in section, of the escapement actuating mechanism of a. linotype machine with my invention applied thereto;

Fig. 2 is a side elevation of my improved devices; and

Figs. 3 and 4 are sectional details showing the parts in different relative positions.

The matrices X are stored in the channeled magazine A and are released therefrom by the escapements B, one for each channel of the magazine, and which are actuated by a series of vertical reeds, the two shown, C1 and (l2, being the outermost ones of the series and alone concerned with the present invention. These two reeds are operated by the reciprocating member C, which is controlled in its reciprocations by the pivoted yoke D, the lifting cam or eccentric D1, the constantly rotating roll D2, the yoke sustaining dog D, the vertical slide Dt, and the finger key The parts so far dcscribed are of the usual construction and are described in the U. S. Patent to Mergenthaler, No. 658740.

My invention is directed to the provision of a simplified form of mechanism for shifting the reciprocating member C laterally periodically so that it may actuate the two escapement reeds C1 and C2 alternately or successively. In' the present instance, this shifting is controlled automatically by the actuating member or its finger key, and so as to take place when said key has been actuated a certain definite number of times. The member C is slidably arranged as usual in the guide plates E and Ct, the former according to my invention being attached to the inner end of a short cylindrical stud or plunger El arranged to slide endwise in the framework to locate the member C beneath either one of the overlying escapement reeds G1, C2. A key or pin E3 engaging in an elongated slot in the stud serves te hold it against rotation and to limit its movements in opposite directions. At its outer end, the stud is formed with a head portion against which bears a spring E4 reacting against the framework and tending constantly to shift the stud to the left to locate the actuating member in operative relation to the outer escapement reed C1. Thistendency of the spring, however, is controlled by a rotary face cam F loosely surrounding the stud El and having extended depressed and raised portions arranged to cooperate with a laterally projecting pin E2 thereon, so as to shift the actuating member to the right or left, as the case may be.

The cam F is rotated by means of an attached ratchet wheel F1, held against retrograde movement by an overlying detent F2, and which is advanced tooth by tooth by a pawl H2 pivoted to a projecting portion of a ring shaped rocker plate H loosely surrounding the hub portion of the cam. Ihe rocker plate is formed with a laterally projecting stud H1 seated in a forked arm C3 fixed to and projecting laterally from the actuating member C, which thus controls the rocking movements of the plate. A spring H3, connected at one end to the outer arm of the pawl H2 and pulling from a fixed part of the machine, serves to hold the pawl in engagement with the ratchet wheel and to advance the latter when permitted by the actuating member.

The action of the parts will now be clear. TJpon each actuation of the finger key D5, the member C is raised to actuate one of the escapements, and through its connections with the rocker plate H shifts the latter upwardly therewith against the action of the spring H3 and locates the pawl H2 in engagement with a higher tooth on the ratchet wheel F1. Then upon the descent of the actuating member, the spring, by pulling downwardly on the pawl, restores the parts to their original position and at the same time causes the pawl to advance the ratchet wheel the distance of one tooth. This progressive advance of the ratchet wheel effects the corresponding rotation of the cam F and brings its raised and depressed surfaces successively into engagement with the laterally projecting pin E2 on the sliding spring-pressed plunger El, which is thus caused to shift the actuating member C into operative relation first to one and then to the other of the escapement reeds Cl and C2 alternately. Thus, as shown in Figs. 1, 2 and 3, the raised surface of the cam is active, holding the member C to the right beneath the reed C2 against the action of the spring E, which tends constantly to move the member to the left. This condition persists until the depressed portion of the cam is brought into engagement with the pin E2 by the con-V tinued rotation ofthe ratchet wheel F1, at which time (see Fig. 4) the spring El is permitted to shift the member C to the left into operative relation to the escapement reed C1, the parts remaining in this position until the raised surface of the cam is brought into action by the further rotation of the ratchet wheel.

As shown in the drawing, the extent of the cam surfaces is such that the shifting of the actuating member C back and forth is effected only after a plurality of actuations of said member or its finger key, so that say V'six matrices may be drawn from each of the two magazine channels alternately. It 1s obvious, however, that by altering the extent of the cam surfaces of the number of the teeth on the ratchet, matrices ymay be drawn from the channels in various quantities, and, if desired, in unequal quantities, as for instance five from one and seven from the other. Y

It will be seen that my improved mechanism comprises parts which are few in number and of simple construction and efficient in operation, and which may be easily applied to existing machines without material alteration therein. In addition, the shifting mechanism, being controlled by the power-actuated member C, is positive and certain in action. The relative proportioning of the parts is also advantageous in that definite quantities of matrices are released from the two magazine channels at the required intervals and without putting the devices through an unnecessary number of shifting operations. Y

As previously stated, I have shown my invention merely in preferred form and byA way of example, and obviously many changes and modifications therein will suggest themselves to those skilled in the art without departure from its scope.
