DAVID s. KENNEDY, or BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTHALEN LINo- TYPE COMPANYyA CORPORATION or EW YORK TYPOGRAPHICAL cor/rrosINc- MACHINE Application filed .dctober 25, 1929. Serial No. 402,401.

zine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the L face of a slotted 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 returned through distributing mecha- 15 nism to the magazine from whichthey started.

More particularly, it relates to that class of machines capable of handling matrix fonts differing as to the size and number of charac- 'ters, such for instance as the seventy-two or fifty-five character display fonts and the ordinary ninety character text fonts now in use. In machines of this class, the keyboard mechanism includes means whereby the finger keys may be op-eratively connected to the.

Z5 magazine in use to effect the release of corresponding matrices of the contained font, .whether the latter be a text font or a display font. This feature is important since the matrices of'the display fonts (being much thicker than those ofthe text'fonts) are .dif-

ferently spaced in the magazine channels and are usually arranged in a different order as to character v The present invention contemplates certain improvements in a keyboard mechanism of the kind mentioned and such as that illuss trat-ed inthe Ackerman Patent No. 1,626,? 7 3, wherein the keyboard is providedwith a single series of slides for the cam yokes, as usual, and wherein these slides are operated from the finger keys through an intermediate series of connecting bails or levers, whichmay be adjusted at will to establish a set of direct connections between the various keys and the 'nection's between certain selected. keys and differently located slides ofthe series when a respective slides when anordinary-text font is in use, or a set of more or less indirect conprovided with cams or yeccentrics.E adapted I under the influence oftrip dogsfE tacooperate with a pair of underlying power.- driven'rolls E The trip dogs E are opera- 100 mode of operation, will be best understood fromthe detailed'description to follow.

The keyboard. mechanism shown is designed particularly for a machinejadapted to be equipped with aregular magazine containing the ordinar ninety .characteretext font or with a special magazine containing the seventytwo character display "font. Ordinarily, the machine is provided ;with

Imagazinesof both kinds, these magazines being movably mounted for interchange and each provided-with a series of matrix releas-a ing escapements, which are actuated by a corresponding series of vertical reciprocating reeds E when a- 'mag azine. isbrought into operative position.

The escapementreeds E arejoperatedby;

pivoted yokes E arranged in twoibanks and In the embodiment illustrated, the slides H,

instead of being operated directly by the key levers F asordinarily, are connected thereto through a series of rocking levers or bails i,

which (as best shown in Figs. 2, 3 and i) are located at the rear of the keyboard F. These bails are disposed in superposed groups, one for eachtier of finger keys, and the bails of the respective groups are pivotally mounted upon transverse rods J fitted into the end walls of a box or frame which latter is adjustable forwardly and rearwardly to set the various bails as a unit in one or the other of two different positions. In their forward position, the bails serve to connect all of the finger keys of the keyboard to the respective actuating slides H so as to effect the release of the text matrices from the regular magazine, whereas, in their rearward position, the bails serve to connect certain selected finger keys to dilferently located slides of the series so as to effect the release of the display matrices from the special magazine.

The present invention is directed primarily to the particular form of connection between thekey levers F the bails K and the intermediate slides H, such connection being intended, not only to afford efficient and reliable contact surfaces between these parts, but also to permit certain desired uniformity in their construction, in order to reduce the cost of manufacture to a minimum. The majority of the rocking bails K employed each comprises (as best shown in Fig. 9) the two hori zontal arms K, K and the connecting bar or tie rod K. The arm K (Figs. 5 and 7) is slightly longer than the arm l3 and both arms are extended rearwardly of the pivot rod J a given distance which may vary, asbetween the bails of thedifferent groups, for

the pivotal movement of the bails.

clearance of the respective tie rods K during The arms K andK of the rocking bails are formed at their forward or free ends with lugs, or shoulders k and with transverse cuts or recesses 70 is located immediately behind said In s.

n the forward adjusted position of the rocking bails, the lugs 70 of the longer bail arms K engage, from above, the reduced'end portions f ofthe key levers F which in th resent instance are arran ed lIl horizontal recesses it formed in the slides H; and, from which each'bail is associated.

below, the said lugs engage the upper walls of the recesses h so as thus to effect an operative connection between the finger keys F and and the slides H. On the other hand, in the rearward adjusted position of the rocking bails, the lugs 72 are withdrawn from the recesses it so as to break operative connection with the slides H but maintain their engagement with the key levers F the reduced end portions 7 of these levers, as willbe noted (see Fig. 9), being extended for this purpose beyond the rear edges of the associated slides H. Motion of the linger keys under the latter adjustment will therefore be transmitted through the longer arms K of the rocking bails to the shorter arms K thereof, and thence tocertain selected ones of the actuating slides H in the manner about to be described.

The slides H, as will also be noted (see Fig. 9), are formed with rearward projections k and contact portions 7& depending the 'efrom and these contact portions are spaced from the rear edges of the slides to provide clearance notches 7L When the bails are adjusted rearwardly, the lugs 70 of the shorter arm K are adapted to underlie the depending portions k of the selected slides H so as to connect the latter through the longer bail arms K to the finger keys F and when the adjusted position of the bails is reversed, the lugs 70 will be located in registry with the clearance notches/i of th slides and thus break the connection. The slides H associated with the longer bail arms K are also formed with depending contact portions 7L2 and clearance notches h but in this 'case, while the notches serve as clearance for the lu'gs'lc in the retracted position of the bails, the depending portions h" are really inactive, the recesses 70 of the arms K being suliiciently wide to clear the depending portions 71 of the slides in both adjusted positions of the operative relation tothe bails of alternate groups, and those of the ren'ia'inmg slides be-' ing located in operative relation to bails of the intermediate groups. It will be understood that the arms of the respective bails K are j differently spaced apart according to the relative location of the two actuating slides with 7 V The arrangement is clearly shown in Fig. 4, wherein is indicated, diagrammatically, the offset relation 60 immediately above the teeth 7? and thus serve to lock the slides against upwardmovement;

of the slidesll controlled from'the upper tierv the 7), the spacing block thus serving as. a con- I ticular slides H contr nesting bar or tie rod as in the form of bail above described. In other cases, where the slides H are used in effecting the release of matrices with like characters from both the text and display fonts, for example'the lower case e and cap C (Fig. 4) ,th'espacing block is elimi nated and the two arms K, K of the rocking bails K are fastened directly together (see Fig.10) so as to act upon the same slide in either adjusted position of the bail box J.

Since only seventy-two of the ninety finger keys are used forthe display fonts, the parolled by the remaining unused eighteen keys should preferably be rendered inactive when the bails are shifted rearwardly to connect the keyboard with escapements of the display magazine This situation can be rencare of by using only the longer arms K of the rocking bails K, the shoulders 70 thereof bearing precisely the same'relation to the slides H as before, but serving only as an interponent to connect the associated slides with the key levers in-the forward position of the bails-and to break such connection in the retracted position thereof. However, it is preferred that the corresponding key levers be locked out of ac tion when thus disconnected from the slides 7 so that in this way the operator will know, by the non-actuation of the key levers, that he has touched the wrong keys;

A simple expedient for accomplishing this result is shown in Fig. 2, where the slides H, connected to the finger keys to be locked, are formed at their lower ends with rearward projections h and upstanding teeth or lips 7 which latter are disposed in operative relation to a horizontal plate or flange J se-' cured to'the front wall, of the box 5.

The plate J is formed with apertures which, in the forward position of'th-e'bail box, adapted to register with the teeth 72, and which, in the retraced position of the box, are adapted to standout of registry with said teeth. In the former case, the apertures permit the slides H to'rise under the influence of he finger keys, while in the latter case, the

lever J from, to a crank arm J deper rock shaft J", which latter is is adjusted rearwardly, the locking of the finger key thus being'effected indirectly from the slide through the bail.

The operation of the parts will now be clear i "When the box J is in its forward positlon'ofadjustment, the longer arms K of i the rocking bails'K in'the six superposed groups will connect all ninety finger keys with the respective actuating slidesH, the shoulders 73 of these arms being engaged in the transverse cuts or recesses h of the slides above the reduced end portions of the key levers F andthe corresponding shoulders 70 of the shorterarms K of the bails being disposed in registry with the notches h of the differently located slides. This is the condition of adjustment required for the release of matrices of the ninety character orltext font from a regular magazine. The other andthe bails K serve to connect the seventytwo active finger keys (those corresponding to the matrices of the display font) to the appropriate actuating slides H, thelugs 10 0f the shorter bail arms K at such times engaging from above the depending contact "portion 71 of the associated slides, and the lugs 70 of the longer bail arms K beinglocated in registry with the notches h of the aining their engagement from below with the key levers Fh Since the general construction of the bails K, including the special. forms noted, will .be substantially the, same throughout'the diii'erent for the different lengths of the tie rods Khonly those of the upper-group,which are associated with the upper tier of finger keys, have been-illus- However, if further details trated herein. of thed1iferent connections between the finger keys and the escapements of the regular I ninety'character magazine and the seventytwo magazine be desired, reference may be had to the Ackerman Patent No. 1,626,773,

- The adjustment of the bail box J (see Figsf 1, 2,v 8 and 4) is effected by means of a small vertically disposed hand lever J pivoted about midway of its length to a fixed bracket J and conveniently adjacent the right-hen d side o-f'tqe keyboard The hand i connected its lower end by a horis.

J5, extenc'ling rearwardly thereg from along ,7 osed longitit' dinally of the keyboard the rear wall of the bail box J and jonrnaled at its opposite ends in V lateral extensions J of a pair of brackets J secured to the upright side posts F of'the keyboard frame. The extensions J are located alongside the end wallsal Zontal l (Fig. 4) of the box J and serve to support the box through the medium of bearing portions J formed on the Walls J and which slidably engage the upper face of the extensions J The box J (see Figs. 2 and 4:) is operatively connected to the rock shaft J by a pair of vertical arms J rising from the shaft and loosely connected at their upper ends by pin and slot connections 7' to the end bearing portions J of the box J.

hen the hano lever J 3 is pulled forwardly (Figs. 1 and 2), the box J throughthe connections just described will be adjusted in the same direction by the vertical arms J to bring the longer arms K of the rocking bails K into engagement with the actuating slides H; whereas, when the hand lever is pushed rearwardly (as indicated by the dotted lines in Fig. 1), the box J will also be moved rearwardly to break the engagement of the longer arms K ofthe bails with the actuating slides H and bring the shorter arms K thereoi into engagement with the appropriate slides H. In order to limit the movement of-the bail box and to locate it in both ot'its adjusted positions, there is .employed a pair of stop screws j mounted in the bracket J 4 and arranged to engage an ear j projecting rearwardly from. the hand lever J (see Fig. 2).
