TYPOGRAPHICAL MACHINE.

Specification of Letters Batent.

Patented Dec. 2a, 1918.

Application filed August 3, 191-8. Serial No. 112,894.

To all whom it 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 Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to typographical machines, such as linotype machines of the general organization represented in U. S. Letters Patent to O. Mergenthaler, No. 436,532, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of av mold, the mold filled with molten metal to form a slug or lino type against the matrices which produce the type characters thereon, and the matrices thereafter returned through distributing mechanism to the magazine from which they started.

More particularly, it relates to a machine of the kind disclosed in my pending application for Letters Patent, Serial No. 52,999, filed September 28, 1915. In that machine, the matrices are stored according to font in two magazines, each provided with its own series of escapements which efiect the discharge of the contained matrices in the required order, and the two series of escapements are controlled by a common set of actuating reeds which tend to actuate the corresponding escapements of both series at each operation; but this simultaneous actuation is prevented by locking devices, one for each series, which are operated in such manner that when one is moved to inactive position, the other is simultaneously restored to active position, thus permitting the delivery of matrices from one magazine only at a time. Such operation of the escapement lockin devices is effected by power driven means under the control of two finger keys, one for each of the magazines, and which are actuated independently to cause the unlocking of the escapements of the corresponding magazine.

My present invention contemplates the use of a single finger key for changing back and forth between the two magazines, as above.

This will also avoid any possibility of mistake on the part of a'careless or inexperienced operator who in the use of two finger keys might strike the wrong one.

In the accompanying drawings, I have illustrated my improvements merely in preferred form and by way of example and as applied to the particular style of machine mentioned, but obviously many changes and variations may be made therein, and in its mode of application, which will still be comprised within the spirit of my invention. Generally speaking, I desire it to be understood that I do not limit myself to any specific form of embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawings:

Figure 1 is a vertical section through a portion of a linotype machine of the kind described above, having my invention applied thereto;

Fig. 1 is a section on the line 1"l of Fig. 1;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a similar view showing the parts in different relative positions; and

Fig. l is a detached perspective of my improved devices.

As my improvements have been embodied in the kind of machine disclosed in my prior application, Serial No. 52,999, before referred to, I have confined the drawings t such parts thereof as are immediately concerned. If desired, reference may be had to such application for further and complete illustration and description of the remainder of the machine.

Referring to Fig. 1, the matrices X are stored according to font in one or the other of the magazines B, only two of which are shown but of which a greater number might be employed if desired. The matrices are released from their corresponding magazine by the escapements C and pass through one or the other of the throats D into the vertical channeled raceway D, whence they are carried to the assembler and composed in line in the customary way. i

The escapements C areof the usual construction, each comprising a rocking lever and a pair of pawls, which latter are projected alternately into the corresponding magazine channel to control the release of the contained matrices. The escapements for each magazine are supported in series in the bar or frame C which may be connected directly to the magazine or pivotally secured to the magazine base frame. The escapements of both magazines are controlled by a single series of actuating members or reeds 0 formed with the rearward projections C overlying the forward arms of the small levers C pivoted to the escapement supporting frame C and which, under the influence of the members C act to rock the corresponding escapements of the two magazines simultaneously in one direction against the force of the springs C tending to rock them in the opposite direction.

Attached to the lower ends of the actuating members C are the springs C pulling downwardly thereon from a relatively fixed part of the machine and of sufficient strength to overcome the action of the springs C so as to hold the lowermost pawls of the escapements in engagement with the leading matrices in the magazines, which are thus prevented from escaping therefrom. To permit the release of said matrices, therefore, it is necessary to raise the actuating members C against the force of their springs C when the lighter springs C will be allowed to act; and this movement of the actuating members is effected by the pivoted levers C engaging beneath the projections C thereon and arranged to be rocked upwardly by the vertically guided rods C operated from the main keyboard mechanism in the usual way.

Since the actuating members C control the escapements of both magazines, their operation would result in the release of matrices from both at the same time were other means not provided. Each series of escapements, therefore, is equipped with the well known transverse rock shaft H which is rotatably mounted in the supporting'frame C and arranged in proximity to the rear ends. of the escapement levers, the shaft being cut away or recessed in the usual way so that in one position it will lock the escapements, while in another it will permit their operation. The shafts H are provided at one end with crank arms which are connected by the vertical rods H to the pivoted levers H operated through the medium of the shorter rods, H H by the power driven cam yokes H H The rods H are constantly urged upward to move their connectedrock shafts to locking position by the springs H which are connected to the pivoted levers'H and pull upwardly thereon from a fixed part of the machine. When the rods H are depressed against the action of the springs H by the cam yokes, they are held down by the spring-actuated locking plate H (Fig. 1 which is provided with hooks H adapted to engage over the rear arms of the levers H. The upper ends of the hooks H are beveled or inclined so that when a lever H is rocked downward, the locking plate is displaced to allow the lever to pass and thereafter snaps back to locate the corresponding hook across the lever and hold it down with the connected escapement rock shaft in unlocking position. The displacement of the locking plate by eitherone of the levers H releases the other if the latter had previously been locked down, and consequently permits the. corresponding escapement rock shaft to be returned to its locking position by the spring H In other words, the arrangement is such that the movement of one of the rock shafts H to unlocking position restores the other to locking position, and vice versa, thus allowing the matrices to be released from only one magazine at a time. As before stated, the power exerted in effecting the operation of the rock shafts is derived from the two cam yokes H and H They are of the ordinary construction, being pivoted at one end and arranged with their opposite ends in position to engage and operate the overlying rods H and H connected to the rock shafts. Between their ends, the yokes are provided with the rotary cams or eccentrics H and H adapted to be rotated by the underlying power driven roll I Normally, however, the yokes are supported at their free ends upon the angular pivoted dogs H and H which hold them at such height as to maintain the cams out of engagement with the roll,

the cams in this position of the parts being held against rotary movement by the fixed stops H and H on the framework. When the dogs are moved, the cam yokes are'tripped and allowed to drop, with the result that the cams thereon are disengaged from the fixed stops and come into contact with the power driven roll, causing the yokes to be rocked upwardly to raise the actuating rods. The tripping movement of the dogs H is effected by means of the vertical slides H and H suitably supported in the framework.

The parts so far described and their manner of operation are fully set forth in my pending application above mentioned, and the corresponding parts are indicated by substantially the same letters of reference. However, in said application, the vertical slides H and H are connected to two distinct. finger keys which are actuated independently, to control the selection of one or the other of the magazines.

In carrying out my present invention, I make use of a single finger key H to control the operation of the two slides, means being provided for connecting the key to the slides alternately at its repeated actuations,

so that it may alone change back and forth between the two magazines in the required order. In the present instance, such means comprise a vertical rocking lever P centrally pivoted to the framework, as at P and provided at its lower end with a pivoted latch or pawl P This pawl rests at its free end upon the rear arm of the key lever H and is formed at its upper edge with a raised portion P adapted to engage overlying bracket plates l5 and P attached to and projecting inwardly from the cam tripping slides I and H respectively, the engagement of the latch with one or the other of the bracket plates being controlled by the position of the lever P which is arranged to be rocked to the right and left for that purpose. The latch P is also formed at its free end with an enlarged or laterally extended bearing head P to maintain its connection with the finger key H in either one of its two positions. As a result of the foregoing construction, when the key lever H is depressed, its motion is transmitted to the pivoted latch P which is rocked upwardly relatively to the lever P to raise one or the other of the slides H, H to trip the corresponding cam yoke, and consequently through the connections before described to move the associated escapement rock shaft H to unlocking position.

The rocking lever P is forked at its upper end, having two oppositely extending prongs P which latter are provided with forwardly projecting pins P and P arranged to be engaged by inclined or cam-- shaped pieces P and P carried by the actuating rods H and H respectively, the relation of the parts being such that the lever is rocked to the left and right by the actuating rods as they are alternately raised by the corresponding cam yokes.

The action of the parts will. now be clear: When the lever P is shifted to the right, its pivoted latch P is located beneath the bracket plate P on the cam releasing slide 1%, thus connecting this slide with the finger key H and the same movement of the lever brings its projecting pin P in en gaging relation to the cam piece P bn the actuating rod H see Fig. 2. In this posiion of the parts, when the key lever H is depressed, the yoke H is tripped and allows its cam H to fall into engagement with the power crivcn roll H thus causing the upward rocking of the yoke and the raising of the overlying actuating rod H", whose movement is imparted to the corresponding pivoted lever H, which, through its connections with the lower rock shaft H, rotates the latter to unlocking position, where it is held by the locking plate H Also during this action, the actuating rod H due to the en a ement of its cam iece P with the pin P rocks the lever P to the left to the position shown in Fig. 3, thus bringing the pivoted latch P beneath the bracket plate P 011 the cam slide H to connect the latter with the finger key, and at the same time locating the project ing pin P of the lever in engaging relation to the cam piece P on the actuating rod H. With the parts in this position, the next operation of the finger key f trips the cam yoke H which is thereupon rocked upwardly by the engagement of its cam H with the power driven roll H and operates the other pivoted lever H to move the upper rock shaft H to unlocking position. The slide H in this last action, and due to the engagement of its cam piece P with the pin P rocks the lever P again to the right and restores it to its original position, as shown in Fig. 2. In other words, the construction is such that the finger key H connected to the two cam yokes alternately by its repeated actuations, and thus operates the locking rock shafts of the two magazines alternately to select first one and then the other, such change taking place each time the key is actuated. It has been before explained that when one of the escapeinent rock shafts is moved to inactive position, the other is restored to active position, this action being secured by the cooperation of the locking plate H with the pivoted lever H.

In order to maintain the rocking lever P in its different positions, the actuating-rod: H and H are provided with small hooks P and P adapted to embrace the projecting pins P and P thereon, the hooks on the two rods acting alternately as the lever P is shifted to the left and right in the manner before described. Thus, as shown in Fig. 2, when the lever occupies its position to the right, the hook P on the rod H engages behind the pin P and, as shown in Fig. 3, when the lever occupies its position to the left, the hook F on the rod H engages behind the pin P The relative arrangement of the hooks P P and cam pieces P P is such that the hooks are disengaged from the projecting pins P P just prior to the engagement of the cam pieces therewith.

As previously stated, I have shown my improvements only in preferred forn'i and by way of example and as applied to the particular kind of machine specified, but obviously many modifications and alte ations therein and in their mode of application will suggest themselves to those skilled in the art without departure from the scope of the invention. Thus, the specific devices illustrated have been developed with particular reference to the structure disclosed inmy previous application, one of my purposes being to adapt my invention thereto with the minimum of alteration. But the broad principle involves the provision of any suitable mechanism whereby the escape ment locking devices may be operated by power driven means under the control of a single finger key in such manner that the successive actuations of the key effect the reverse .operations of the locking devices to change back and forth between the two magazines. However, the particular devices herein employed for this purpose are believed to be new in themselves, and are such that they might be used to subserve a different function, as for instance in connection with the so-called double e arrangement, wherein duplicate matrices are drawn from alternate channels of a magazine.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United. States, is as follows:
