TYPOGRAPHICAL MACHINE.

Specification of Letters Pate;

Patented Nov. 22, 1921.

Application filed July 3, 1920. Serial No. 393,856.

To all whom it may concern:

Be it known that I, DAVIE) 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 drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent to O. lilcrgenthaler K0. $36,532. wherein circulating matrices are released from a magazine by the manipulation ot a keyboard in the order in which their characters are to appear in print and then assembled in line, the composed line trans terred to the nice or a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned through a distributing mechanism to the magazine from which they started. My present invention is directed to an improved locking device for the keyboard of such machines and also contemplates the provision of means whereby the locking and unlocking of the key board is etlected automatically at times when the finger-keys should not be actuated, all as will be fully pointed out in the detailed description to follow.

In the accompanying drawings, 1 have shown my invention merely in preferred form and by of example, and as applied to a machine of th class stat d, but obviously many changes and alterations may be made therein and in its mode of application, which will still be comprised within its spirit. Generally speaking, l desire it to he understood that I do not limit inyseli to any specific form or embodiment except in so far as such limitations are specified in the claims.

Referring to the drawings:

Fig. 6 is a side elevation of the lower portion oi the keyboard'as represented in Fig. 5 with certain parts shown in section to illustrate the manner in which they cooper c keyboard herein illustrated is of the rep 2.1- linotype variety comprising the supporting frame A and the series of horizon tal finger-keys or key levers B pivotally mounted therein for vertical movement upon the transverse rods A which sustain them in rows at different levels in the customary way. The finger-keys are guided in their vertical movements by the front and rear plates A and A fixed to the supporting frame A. and formed with elongated slots wherein the opposite ends of the finger keys are arranged, it being understood of course that the extent of the slots is such as to permit the required actuating movement of the finger-keys. The front plate A which occupies an inclined position on the supporting frame to cooperate with the forward ends of the finger keys in the several rows, is clearly illustrated in several'ot the figures, its elon ated slots being designated a. At their rear ends, the linger keys B are engaged with the single series of vertically movable bars or slides B" connected at their upper ends to the two series of trip dogs B controlling the engagement of the cams B of the yokes B with the power-driven rolls B" for the operation of the escapement actuating rods or reeds B The foregoing parts and their mode of operation are so well known that any further description would be superfluous, but if desired reference may be had to the Dodge Patent No. 530,931.

As before stated, my invention is directed to an improved locking device to prevent the actuation of the finger keys when. the

teyboard is not in use. stance (Figs. 1, 2 and 3), such locking device is in the form of a plate C slidably mounted upon the fixed front plate A and iormedwith elongated slots 0 through which the forward ends of the finger keys B ex- In the present iii-- tend, the plate C thus being practically a duplicate of the plate A It will be seen, therefore, that by adjusting the plate C backwardly and forwardly upon the fixed plate A the finger keys B may be locked or I of the finger keys, which are thus locked against depression or actuation. In other words and more broadly speaking, the keyboard is provided with adjustable locking means arranged to be engaged with and disengaged from the finger keys directly and notwithstanding their disposition at different levels, so as to prevent or permit the actuation of the keys according to the adjustment of the locking means. In addition to its locking function just described,

the plate C also serves when adjusted rearwardly to active position to restore the finger keys and the connected parts to their proper condition. Thus, if at the time of adjustment of the locking plate, a finger key should bedepressed (due for instance to the binding or sticking of its actuating slide 13 the plate by acting with a cam effect beneath the forward end of such finger key will rock it backup to its normal horizontal position.

Any suitable means may be employed for adjusting the locking plate to and holding it in its adjusted positions. For such purpose, thereis herein provided a rotary cam plate D (Fig. 4) pivoted by a pin D to the fixed front plate A and arranged in engagement with the forward edge of the plate C. As will be apparent from the drawings, when turned anti-clockwise, the cam plate pushes the locking plate rearwardly to active position as shown by the full lines in Fig. 3, and when turned clockwise, allows the looking plate to slide forwardly by gravity to inactiveposition as indicated by the dotted lines in said figure. To facilitate its turning movements, the cam plate is provided with a depending grip or handle portion D which also serves as a stop to arrest the plate in its diiferentpositions.

It is particularly noted that, in the fore going arrangement, the parts are extremely simple and can be made at small cost and applied to the keyboard without the slightest difficulty or delay, and this without involving any radical alteration in the existing parts of such keyboard. In addition, the arrangement is "strong, durable and compact and such that it may be easily and conveniently manipulated. These and other advantages will be apparent to those skilled in the art. 7

Referring to Figs. 5 and 6, the arrangement therein illustrated is intended to provide for the locking and unlocking of the finger keys automatically by the assembling elevator E wherein the matrices are composed in lineas they are released from the magazine by the manipulation of the key board. The elevator normally occupies the receiving position shown by the full lines in Fig. 5, but after the composition of each line, it is raised to the delivery position indicated by the dotted lines in said figure for the transfer of the composed line therefrom by the shifter E and then low- 'ered to its receiving position for the composition of the next line. These raising and lowering movements of the elevator are effected, as usual, by means of the hand lever E connected thereto through the transverse rock shaft E the rearwardly expanding arm E and link E". In carrying out my invention, I make use of the locking plate- C above described and provide connections between it and the elevator whereby the plate is moved to its active and inactive positions as the elevator is moved from and to its normal receiving position, respectively. To this end, the rock shaft E is equipped with a collar F formed with a lip or shoulder F arranged to cooperate with a lug F on the upper side of a bell crank lever F pivoted to the fixed front plate A of the keyboard. This lever F at one end engages the lower edge of the locking plate 0 and at its opposite end is connected to a spring F pulling. thereon from a fixed part of the keyboard frame. By reason of this construction, when the assembling elevator is in its lowermost or receiving position as shown in Figs. 5 and 6, the lip F is in engagement with the lug F and holdsthe lever F retracted so as to permit the locking plate 0 to occupy its forward or inactive position as required; but when the elevator is raised from its receiving position, the lip F is disengaged from the lug F due to the turning of the rock-shaft E (see'the dotted lines in Fig. 6), and releases the spring F", which thereupon operates the lever F and shifts the locking plate C rearwardly to its active position. This latter condition of the parts will maintain until the elevator is restored to receiving position, when of course the lip F re'e'ngages the lug F and withdraws the lever F against the action of the spring F so as to permit the locking plateto slide forwardly by gravity back to its inactive position.

There are times when the operator may wish to lockthe finger keys against actuation when the assembling elevator is inreceiving position, as for instance when he leaves the machine or desires to make adjustments or repairs. The automatic connections above described are therefore arranged to be made or broken at will, which is herein accomplished simply by attaching the collar F to the rock shaft E" by means of a pin and slot connection F As apparent, a slight axial movement of the collar F breaks its connection with the rock shaft E and releases the spring F", which acts immediately to shift the locking plate rearwardly to active position. It hardly needs to be stated that the force of the spring F should be and is insufficient alone to turn the rock shaft E when the collar F is operatively connected thereto.

As previously stated, I have herein shown my invention only in preferred form and by way of example and as applied to a particular kind of machine, but obviously many modifications and alterations therein and in its mode of application will suggest themselves to those skilled in the art without departing from the scope of the invention.

Having thus described my invention, its construction and mode of operation, what I claim is as follows 1. A keyboard for typographical machines including, in combination, a supporting frame, a series of finger-keys movably mounted therein and disposed at different levels, and locking means adjustable to active and inactive position independently of the actuation of the finger-keys and ar ranged to be engaged with and disengaged from the finger-keys directly so as to prevent or permit their actuation according to the adjustment of said locking means.
