. STEFANUS NIELSEN, OF BROOKLYN, NEW YORK.

TYPE-WRITER.

Application filed May 10, 1916, Serial No. 96,501.

To all whom it may concern:

Be it known that I, S'rEFANUs NrsLsEN, a citizen of the United States, residing in the city of N ew'York borough of Brooklyn, county of Kings, an State of New York, have invented a certain new and useful Type-Writer, of which the following is a specification.

This invention is a typewriter, and the object of the invention is, more particularly, to improve typewriters of the class to which my co-pendin application Serial Number 17771, filed fiarch 29, 1915, relates.

lFrom a more specific standpoint, the obtanically driven means controllable by the erator, and are returned to normal posi- ..on, out of engagement with the platen, by further mechanical means independent of the operator. There has been an objection to machines of this character because of the fact that, if an operator were actuating the machine at high speed the type bars might not be returned quickly enough for a subsequent operation, and nomeans was provided for allowing of the subsequent operation-of any particular type bar until it had been reset to its initial, inoperative position. The present invention provides means which entirely overcomes this disadvantage and allows the machine to be operated as rapidly as the most skilledoperator can actuate the same.

Features of the invention, other than, those specified, will be apparent from the'. hereinafter detailed description taken in conjunction with the accompanying drawin s.

n the accompanying drawings, I have illustrated different practical embodiments of the invention, but the constructions therein shown are to, be understood as illustrative,

only, and not as defining the limits of the.

invention.

Figure '1 is a vertical section through a typewriter embodyin the present invention, sald section being ta on on the broken line XX of Fig. 2.

Fig. 2 is a'rear view of the machine, with certain parts broken away, or omitted, in

the interest of clearness.

Fig. 3 is a perspective detail showing a part of a type bar action, the type bar belng shown in normal or rest position.

Fig. 4 is a view similar to that of Fig. 3, but illustrating a slightly modified form of type bar action.

Figs. 5 and 6 are details showing difl'erent portions of the cycle of operation of the preferred form of type bar action.

Flg. 7 is a detail of one of the type bars of the machine, and-the crating the same, and

Fig. 8 is a detail perspective of one of the elements of the modified construction.

Referring to the drawings, the type bars are designated by the reference numeral 1.

:Ihese bars are pivoted at 2 in slots 3 formed in a supporting segment 4. The type bars are mounted radially of the segment and are adapted, when actuated, to strlke the platen 1 at a common. printing point 5, being mechanically driven to said printing point by means of tension springs 6 in the manner clearly set forth in my co-pending application hereinbefore referred to.

Type bars 1 are held in their normal or rest positions against the tension of springs 6 by stop members 7- which are pivoted at mechanism for op- 10 to brackets 11 mounted on a cross-beam 12, which, inturn, is supported by lugs 12 formed on the frame of the machine.-

13 designates the finger-keys which constitute the keyboard, and, in the preferred embodiment of the invention shown in Figs. 1', 2, 3, 5 and 6 of the drawings, each key 13 is provided with a stem, to the lower end of which 1's pivoted one arm-of a bell-crank 14 mountedfor 15. The other arm of bell-crank 1 is pivpivotal movement on a pin oted to la push-rod 1-6, the function of which pus rod is to actuate its cooperating stop melt; er 7 in order to release tho-corresponding type bar '1 and allow the associated. sprmgfi to move said bar to the print-.

' ach push rod 1J1 which is mounted between rollers 19 'ourcam 12, -When any particular key 13 is do;

as a guide piece18" 60 link will be disen is advanced one-fifth of a complete rotation. Thus, bars 27 successively operate upon the links of the keys successively actuated. If more bars 27 were employed, the gearing would be such as to advanceone bar at a time to proper, operative position.

It will be manifest that some means should beprovided to govern the pivotal movement of links 9 so that the; will be presented to bars 27 1n such positions as to v be readily actuated thereby, and removed from engagement with said bars as soon as the resetting operation of that particular type bar is completed. To this end, each type bar is provided at its rear end with a laterally projecting pin 26 which rests upon a guide tongue 26, and each sprin tongue 26 is of sufiicient length to exten beyond the termini 'of the travel of the pin 26. Guide tongues 26 form a part of a plate 41 fixedly mounted on a. cross-beam 46, as shown in Fig. 1. Cooperating with tongues .26 is a like number of sprin tongues 27 mounted attheir forward en s on bent-up portions 43 secured to a cross-bar 44. The forward ends of tongues 27 are in spaced relation to the corresponding ends of tongues 26*, while the rear ends of tongues 27* rest lightly upon tongues 26* near their joining with plate l1, as shown in Fig. 3. Each pin 26 0t one of the links 9 cooperates with one pair of tongues withwhich said pin engages, and the inclination orf'curvature of said tongues is such that the hookshaped portion 32 of each link is presented to the operating bars27 in proper position, and, after the llnk has been retracted to the desired extent, said tongues cause the link to be disengaged from the actuating bar 27 The manner of operation is clearly shown in Figs. 3,5 and 6. Fig. 5 shows the positions of the parts when the type bar is at the printingpoint. At this time, link 9 is in its forward position and resting on the lowest portion of guide tongue 26. The letter having been printed at the printing point, the platen advances, thereby allowin the spring motor to rotate shafts 29, witthe result that one of th bars 27 engages with the hook-shaped portion 32 at the end of link 9, last operated. Bar 27 advances, carrying with it link 9 and retracting 'said link to rest position, with spring 6: under tension. However, it will be noted from, Fig. 5 that, as the link is retracted, its pin .26 rides on. guide tongue 26, which slopes upwardly. The result of this construction is such that, when the link has. been-re tracted sufliciently far, the book 32 offthe ged from bar 27. Guide tongues 26* and 2 b are. so proportioned that this disengagement will occur as soonaspin "26 haspassed under the free end of the co: operating spring tongue 27", simultaneously 6 with whichthe cooperating stop 7 will have 1113111181 specified,

operation of the same ey, ',stop 7 would be 1 20 oscillated, notto, release projection 8, but

engaged with the projection 8 on the link and locked the link,in retracted position. The positions of the parts at this time are as shown in Fig. 2}, and they remain in such positions until the type bards again. released by its key? 13, at which time pin 26 will ride idly up and over its 'springtongue 27 until approximately that time at which the type bar reaches the printing point,

whereupon it will have traversed the length of tongue 27 b and will fall into engagement with its-tongue 26 or into the initial position shown in Fig. 5. Each and every ype bar operates in the ing released by, its finger-key and actuated by its spring 6 to the printing point, after which it is returned Y to its rest position by one of the bars 27, to which its associate link is directed and subsequently removed by.,the cooperating 86 tongues 26" and 27*.

As heretofore stated, itmay happen that, when one letter is operated twice in succcssion, if the second operation too closely follows the first, not suflicient time has 90 elapsed to allow of the resetting mechanism returning the type bar to its rest position. before the second operation-takes place. -In this event, only one im rcssion would be made, and this dilficulty as long been recognized in power-driven typewriting ma. chines.v According to the present inventipn, however, means is provided whereby the" waiting for the completion of.the resetting, 2) operation is rendered unnecessary, thereby 1010 greatly increasingths spqbd at which, the machine may 'be operated. This means is embodied, in the preferred-form, in aheel 25 formed on each stop 7, and so positioned as to underlie the lower edge of link 9. The function of heel 25'is"noth1ng more or less than to trip hook 32 of-link 9 free and clear of bar 27 during. the resetting operation, since, by the provision of means to accom: plish this result, the type bar is rendered at l all times within the control of the operator. Assuming, therefore, that link 9, shown in Fig. 5, has been engaged by onset the bars 27 and partially retracted, it would be normally maintained in engagement with said bar until the retracting operation was com pleted. However, if the typist is operating the machine, high peed and wishes to fol- W, the preceding 0 eration b another to lift heel 25 into engagement with, and, thereafter raise, link 9, w1th the result Quit hook 32 of said link is disengagcdirom bar 27 as shown in Fig. 6. Spring-6 will havc'umi been placed under -.sufiic1ent tension, and type bar 1 retracted tojsuch. extent, that, i even at'this' point, the second printing-operation will be performg.mi certainty'and the proper impression'made.- i

The mechanism described, therefore, places all of the type bars under the will of the operator'at all times, irrespective of the resetting operation, and, accordingly, the

5 machine can not fail to carry out the operations of the most skilled operator. To insure proper coiiperation between .heel 25 and link 9, i'rrespectiveoflthe particular portion or elevation of the spring tongue :26- with which it is in engagement, the lower edge'ol link'9 is preferably curved or'shapedin such manner as to compensate for the dilference in elevation of different positions. The :lower edge of each link is so positioned that i5 during the operation of stop 7 in releasing theprojection A, when the links are in normally retracted or rest'positions, the heel 250i the stop will not come into engagement with the lower-edge of the link since at such times engagement of the heel with ,the link is not only unnecessary,.but would increase the work to actuate the stop. It is only during the resetting operation of any particular link that it is within the zone of operation of heel 25. I

Because of the fact that the type bars are pivoted on a segmentand that the resetting bars 27 are tangential to said segment there is necessarily a slight difference of relation 80 between the pivotal point on the various type bars and the difi'erent points along the length of the bars27- with which therespective links cooperate. In order to place the links Sat all times during the resetting operation under thecontrol of the heel 25,

the. contour of the lower edge of each link.

is shaped so-that that portion ofthe lower edge of the link which is in juxtaposition with heel 25 during any particular period 40 of the resetting operation will be positioned relative to said heel that when the heel is operated, it will impart to the link just suiti- .c1ent movement to lift'it free from the resetting bar 27.

that shown in Figs. 1,3, 4, 5, and'G.

Moreover, because. of the fact that the typebars are pivoted for movement radially of the segment While the links 9 are mounted perpendicular to the tangential bars 27, it

will be manifest that only that link which cotiperates with the bars 27 midway of the length thereof will lie in the same plane as its coiiperating type bar. The links at either i side of this central link will lie in different planes of their respective type bars. horder to obtain proper pivotal action between the 7 type bars and the. links, those portions of the links whi'ch are pivoted to the type-bars should lie in the same plane,. fas the types -bars,"and, accordingly, such links as are not in parallel relation with their ,coiiperating type :bars are twisted near their points of pivoting to bring the ivoted portion of the links into parallel re tion with said type Thus, the link shown in, 45 Fig. 7 is of slightly difierent contour than bars. Thus those portions of the links" which are pivoted to the type bars are parallel thereto and form proper pivotal connection.- T

In Fig. 4 is shown a slightly modified 1 form of means, controlled by the lingerrkeys,

for releasing the type bars from their set positions. 111 accordance with this modificzv tion, the key 13 is provided with a stem 48, to the lower end of which is pivoted a dog l9 normally maintained in alinement with stem l8 by a spring 49. 51 is a rockshait carrying a fixed arm 50 adapted to,

be engaged by dogACQJ The construction thus far described is substantially the same as that illustrated in my co-pending application referred to, the parts being so arranged that dog. 49 will leave arm 50 after.

the key has been depressed tora certain extent, and thereby allow the shaft to return to its initial position after having been oscillated by the depression of the finger key. Rock-shaft 5l'carrics at its rear end a stop 52 and a crank-arm 53, both of which are fined on the shaft. Stop 52 is adapted to engage with a projection 5i, which is pivoted at 55 to link 56, which link corresponds to link 9 of the preferred construction, The spring57 serves to hold projection 54: m a norn 1al,,extended position, because of its engagement ,with a movei'l'ient limit'ing member 58 secured to said projection;

\Vhen rock-shaft 51 is operated by the depressing of key 13, stop 52 is oscillated out of engagement with projection 54, with the result that spring 6 forces the type bar 1 to the printing point. lVhen the type bar is subsequently returned through. the medium Iofthe resetting mechanism hereinbefore described, projection 54 will be retracted against the tension of its spring 57 and, in

this retracted position, will pass by stop 52. As soon as it has passed stop 52, spring 57 will throw the projection outwardly into engagement with the back end of the stop, and the parts will be locked in rest position.

It will be noted that, whenever shaft 51 is rocked, arm 53 will be moved in accordance therewith, and this arm is so positioned that its end will overhang one end 60 of a lever 61 whicliis pivoted, at 62, to a suitable support 63, The oscillation of rock-shaft5l will thus serve to pivotally move lever 61, depressing end 60 and raising the opposite end.. Said-opposite end is formed to underlie the lower edge of link 56, and, as a. re-

sult the pivotal movement of said lever, in the manner specified, serves the same purpose as' the operations of heel 25 in the referred construction, viz., to release the from the resetting mechanism when the key "is actuated before the resetting mechanism has completed theresetting operation.- It thus appears that, in'the construction descmbed, the machine may 'beoperated at rut inv least intcrit cl positiveuess.

which the releasing ypo act Ill] lrlnn 'tliie resetting lllQCllitnism is accomplis ed have been shown, and, in like minn'ier, various modifications might be illustrated With reference to the reset ting mechanism. However, I have shown only one, which illustrated in Fig. 8. In accordance with this modification, instead of having plates 28 With bars 27 extending between them, which bars common to a plurality of type bar actions, each type bar action is released by a separate plate 58, havin projections 59 corresponding to bars 2'7, it being understood that the various plates 58 are successively positioned on drive-shaft 29,to which movement is imparted. here-- inbefore described. Thus, instead of having a plurality of bars 27 common to a plurality of type bar actions, each action has its own particular plate 58, having its resetting projection 59.
