Tc coll ulhoirt it may concern.-

Be it known that I, Gnoncn W. DoNNrNe, a citizen or the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Electrical Type-Writer Selecting and Operating Means; and I do hereby declare the following to be'a full, clear, and exact description of theinvention, such as will enable others skilled inthe art to which it appertains to make and use the same. I

The object of this invention isto provide animproved means for operating and con rtrolling 'the Writ ng mechamsm'for electrically-operated type-writing machines. Another objectis to provide animproved form of selecting and operating magnets" and connected parts for operating the type-bars,

parts.

the type-head-shiiting mechanism, ribbon mechanism, its reversal, and othe r operable Anotherobject is to provide an improved form of key or switch for controlling and opand operating mechanism.

A further object is to provide key mechanism which will effect a cycle of movement of crating such elctrically -operated selecting operative parts, 'as follows: first, electrical connection with a selecting magnet to attract an armature-carrying pawl .or lever that 18 suitabl fulcrumed and which is thereby positioned for further operation;

second, switching of the curren't to a second magnet ,to eiiect electrical connection with a magnet to attract the armature of an actu- .ating power device, during which latter movement'the pawl or lever is engaged by the power device and the operative parts pose; and, third, to break the circuit in order tocause return of the said parts to normal position, all upon the down movement of the key.

- A further object is to provide novel constructions and arrangements forefie cting these said operations.

7 Another object of this invention is touprovide an improved form of shifting means especially adapted for use in an electrical type-Writer where there is a plurality or a se ries 'of characters mpunted on a head screwed- Specification of Letters Patent.

'to each type-bar and a relative movement is necessary between platen or writing surface and the position of the type on the type-bar When the latter is moved to the printing lo"-.' cation to cause thecharacters to be printed.

A further object is to provide in a'typewriter type-bars each provided with a mov able head carrying a plurality of-- type,

A further object is to pr id a, Writing ype-bar 'provided with a mova. 1

head carrying a plurality of type means for effecting a shifting of the type-head thereby to position one or the type on the head for printing, an actuator disposed independent of and contiguous to the type-head for efl'ectfing operation of the type-head-shifting -mec ha-nism, selecting-magnets arranged to control the type-bar-operating mechanism, selectin ariagnets arranged to control and eilect operation of the typeheadoperatin mechanism, selecting-magnets to controd and effect operation of the type-head, actuator for shifting the type-head, a universal operating device, magnrts for controlling and operating the universal power device, and means for efiecting return of the parts to norma hposition. 3 Another object is'to. provide a key con- Qruction having a slight depression which Will perform a dual function, all independently of the return of the key mechanism to its normal position.

I. Another object is to provide a key construction which will close the electrical circ'u'it, switchit to another circuit, and finally break lthe circuit and simultaneously therewithi-c-ut out the current, all upon the depression of the key and indep :ndently of the Another object is to provide a type-.writer, particularly a type-writer known as a flat plat-en book or commercial machine, the writing mechanism movable over the writingsurface with a stationary keyboard, thereby obviating the necessity of the operator reaching for or following after the writing mechanism in its manifold movements and locations, as is now necessary in machines of this character. This same key construction may be applied where the writing mechanism or carriage remains in one spot and the book ,and flat platen are made movable electrically for line and letter spacing, or the writingmechanism carriage may be operated for letter-spacing and the book and platen moved for line-spacing.

A further object is to provide a key con struction which will, when cooperating with an outside source of power and when operated, perform several functionsnamely,se lect, operate and permit return of the operated parts independently of the release .of the key. The same may be employed to operate the typing and spacing andribbomfeeding mechanism, another to shift the type-head and spacing and ribbon-feeding mechanism, another to shiftthe type-head, and another to shift the ribbon, and another for operating any desired mechanism on the machine.

Another object is to provide a key which will switch the current from one magnet or set of magnets to another magnet or set of -magnets without cutting out the current or breaking the first circuit until the second circuit has been closed, thebreakon second circuit and cutting out of current being made upon the complete depression Of the key.

' With these objects in view and with others my invention comprehends the construction, arrangement, and combination of parts, as hereinafter described and claimed.

In the accompanymg drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts, I have illustrated one of many embodi ments of my invention, it being understood that other embodiments thereof and a differ ent arrangement of the parts may be utilized without departing from the. spirit of my invention.

1n the drawings, Figure 1 is a view in perspective of a type-writing machine, showing my invention. Fig. 2 is a plan view, the top plate being removed. Fig. 3 is a vertical sec- -tion through the middle of the machine.

selecting-magnets, a pawl, a universal powerbar carrying an armature, a magnet arranged to attractthe armature and power-bar for operating in this instance a type-bar. Fig. 17 shows the type-shift mechanism in elevation with its respective selecting pawl and the universal power-bareoperating device, and Fig. 18 is a fragmentary view showing the latter parts in perspective. Figs. 19, 2t), and21are diagrams showing movements of contacts.

In the several views, in which. the same characters of reference indicate the same parts, in a frame A, Figs. 2 and 3, are secured fnlcrum-rods a a, that carry links a a3, respec: iiively, which latter support bent levers A, A each of the bent levers being supported by a link a and a link a preferably arranged in pare allelism. When one of the bent levers A is depressed, it will rock a type-bar A? through the medium of'a lever c and conneotmg.

links a c. A spring (i shown as connected atfits two ends to the links a a? at opposite sides of the" ivotal supports of the latter, operates to maintain said links normally inclined upwardtoward their points of ivotal connection ,with the bent. lever A? and to. return the links and bent lever to normal position after depression to effect printing.

A universal power-bar B extends between the links a, and 0, and is supported at each end. by an arm B pivoted to. the side plate of the machine. pivoted an armature alever C, carryingan armature 0 arranged to, be attra ted by ne of a series ofelectromagnets 0- carried on a bar ctof fiber or other suitable non-magnetic material. "A retractile spring 0 serves nor mally to retain the "armature-lever C in the position shown and away from its operating, magnet. The lower end of each of these ar mature-levers C has a foot or offset a, made On each of the links a? is ICC hook-shaped, as shown. that when the an ile spring will move the foot away from its position of engagement with the ower-bar On the base-plate is mounte an electromagnet D, having, preferably, two coils d i constituting a power-bar-operating magnet. All-armature d is suspended Within the influence of the magnet D, being swingingly mounted on a bar (Z that is carried by two levers 1901 the latter being pivoted to the side of the machine. The levers d each have an arm 43?, that is pivoted to one of the arms B A retra'ctile spring I) serves to retain the armature, the universal power-bar, and the connected parts in the position shown in the drawings-that is, away from the electromagnet. Consequently when the electrm magnet'D is energized the armature will be attracted nd rock the arms (i and B down-- ward and also the universal power-bar B. Now should any of the selecting-magnets be energized, and thereby bring one of the hooks o under the universal power-bar, and thereupon the current be switched to the electromagnet .D,- the power-bar will engage the hook c in its downward movement, and thereby operate the corr'espondingtype-bar through the aforesaid connecting members, the hooks preventing disengagement while jghe parts are being acted on by the powerar. v 1

Immediately underneath each of the links a? is arranged the universal bar E, that rocks an escapement disposed at E and thereby effects'the letter-spacing of the writing mechanism in the usual and well-known manner. Hence when any of the links a are depres d to cause the operation of the key-bar the uni- 2o versal bar will be operated.

In order first to energize the proper selecting-magnet and then energize the powermagnet, Ihave provided a key or switch, as shown in Figs. 6 and 7.-' The key F com 2 5 prisesa stem f arranged to reciprocate in a metallic bushing f mounted in an insulating plate f of any suitable-material. On the stem j' 'is a reduced portion that carries a coiled spring f", arranged to return the key 0 to its normal position after having been de- I pressed. On the lower ortion of the stem f t:

v is pivoted 'a substantial yT-shapedterminal armf being carried on a screw f A platespring f 9 is secured on the said terminal '5. member and has a forked extremity enibrac-,

ing the shank of said screw between its head and the face ofthe arm. This spring is 'slightly bowed in order to produce a certain amount of friction and thereby retard the 40 movement of the'terminal armon the keystem. It is to be understood that when the key F hasbeen depressed to a point where the pin f shall have been operated to rock and force the terminalarm or contact-plate f around to cause the circuit to be'broken it will then rise under the stress ofaits spring f f 6 and move upward a short distance before Upon the key being depressed the terminal.

arm will first engage a stationary terminal f "lt'will be observed from Fig; 5 that the contactingfaces of these terminals are arranged obliquely to thepath of movement of I 6: the key and that they are insubstantial parcontact with the terminal f and leave the "terminalf as shown in F ig. 14. A slightly- -pressedit will be observed that a circuit in-' allelism. In proximity to the terminalf is arranged a third terminal f, but insulated therefrom. The upper face of this terminal f is also made oblique and is substantially a continuation of the oblique contacting face of its adjacent terminal. The mechanical operation of this switch is as-follows: Upon the key being depresseda short distance the terminal plate or camwill first strike the ter' minal f (see Fig. 13,) whereupon the inclined faces will cause the terminal arm to' 4 rock, as shown, and upon further depression of the key the ten al will slide along the engaging face of the terminal f until it will further depression of the key will cause the terminal arm to rock still more on its pivot, and its contacting face will have a sliding engagement with the terminal f as shown in Fig. 14. A slightly-further depression of the key will cause the arm f of the terminal to strike a stationary pin f that Wlll rock the arm stillfurther-and cause it to break contact withthe terminal f thereby breaking the current, deenergizin'g the magnet, andpermitting return of operated parts irrespecj tive of release of key. Upon the key being released itsretractile spring will force the same upward. The terminal arm will be partially returned to normal position by the said stop-pin on its return movement. When the arm" f strikes the insulating-platef, the

[further upward movement of'the same will cause the terminal arm to be rocked until it resumes its normal position in alinement with the path of movement of the key-stem;

One pole of'a suitable source of electricityisconnected with all of the key-bars. A conductor from the other pole of said source is 165 first passed around a selecting-magnet c and is then connected with the terminal 1 there being one of the keys F, as above described, for each of the selecting-magnets. Another conductor, led from the said last-ire mentioned pole of the source of electricity, is connected with the power-magnets .D and is then connected with the terminal 1. Con sequently when. any of the keys are deeluding the a propriate selecting ,magnet is first closed, w 'ch will energize the magnet to move its lever to bring the operating parts, hereinbefore described, into position of engagement. 7 The further movement of the key will position the terminal arm f upon the terminal f, and the current is transferred to that circuit including the terminal f and the power-bar-operating magnet D. The energizing of the magnets is so timed that the foot of the selecting-magnet lever remains in its engaging position until it is engaged and moved by the power-magnet depressing the universal power bar B. A

slightly-further movement of the key will cut 1 Jo position its book in the path of the power-bar -that into '0 eratlon, and on the further out the power-bar and operating-magnet, so that all parts operated electrically may return or be returned to their normal positions by the retraetile springs. It will be observed that even thciughthe key be reta ned in its depressed position the circuits are opened and the typebars,,&c, are at once returned to' their normal position, and should another,

key be depressed before the said key is re leased the movement of the type-bar result; ingtherefrom will not cause the latter type l bar to strike the; former, as is the case in the usual-form of type-writer when one key is operated beforeano-ther key is released. When the said key is released, since the terminal arm is not rocked back toits normal position until the key-stem has moved upward a short d stance there will be no contact or even approximation of the terminals, and consequently neither of the circuits will be 1cilosed .until asubsequent depression of the ey. I

In practice I find that I can constitute the power-electro'magnet C oi the same or of dif ferent resistance than that of the selectingmagnet 0 In some instances I find it is de- "sirable to have the resistance of the powermagnet less than that of the selecting-magnet, though I do not wish to limit myself to constituting these magnets of, different resistance. When the power-inagnet is of less resistance, it will be understood that when the'terminal. arm f moves over the terminal f to the terminal 1 the moment that this terminal arm f 7 bridges the terminals f f tl1e cur rent will naturally flow ingreater strengththrough the tcrminalf by reason of its in- .clusion in a circuit of less resistance than that includingthe. terminal f However, it is tobe'understood that the movement of the terminal arm 1 from the terminal f to f is so rapid that movement of" the parts will be Y only as desiredthat is to say, the selectingmagnet 'will have been caused to perform its functi on of directmg its respective pawl to efore the power-bar begins-to move. Then.

the current is thrown into the terminal f the current will immediately be through'the terminal f to the power-magnet to bring movement o the terminal armf on the tore minal f 11 this will efiect complete operation of the power-magnet. In Figs. 19, 20., and

211 have illustrated the variouspositions of the terminal arm f in its path of movement, beginning with the terminal f then leaving .thesame and simultaneously taking upon the terminal f and finally leaving that terminal f and breaking the circuit. The important,

desirable, and intended purpose of this construction isthe avoidance of the creation of a multiple circuit when the terminal arm f is pursuing its movement while in contact with 5 terminal f and thenthe terminal f v amino this respect particularly m'y inventi is distinguished,and differentiated from the present at. This has been accomplished by isolating the selecting-magnets and their re spective circuits from the operating or work magnet and its circuit. It will be'readily un- 'derstood that the select'mg magnets, by rea son of their required number and location, will bevery small Whereas the work or operating magnet. is much larger to" develop the "requisite power to effect movement of a part suchas a ty-peebar, shifting and spacing mechanisms, &c. It is obvious that if the Wiring on the selectingen'uignets'is to give re sistance equal tothat of firework-magnet, as

for permitting their working in mult ple cir tionpof a current sufiicient to energize the work-magnet. I In Fig. 8 is shown a modified form'oi key,

in which the key-stem H is connected with one pole from the battery and when depressed first makes contact through a disk h with a flexible terminal h and closes the'selecting-circuit, energizing the selecting-magnet, and attracting the-lever and armature.

A further movement of the stem causes the insulating-disk 71 to strike the flexible ter-' cuit, this wiring on these selecting-magnets minal 72 at 72 and force the same away'irom the disk 71 instantaneously therewith or just before the disk 7L2 contacts with flexible terminal h, thereby switching the current from one circuit, which isthe selecting-circuit, to the other, which isthe power-magnet circuit, and energizing the operating-magnets, which, attracting the armature on the power-bar, cause the other parts of the .machine to operate. A further depression of the stem H- cagries the disk b below the projection on the flexible terminal h and instantaneously. therewith the insulating-disk h strikes the'fiexible terminal h at h and forces the same away from disk 7L2, thereby breaking the circuit and cutting out the current, permitting the various operating parts to return to their normalposition without releasing the key carried on stem H. Thein sulating-disk its now being forced down between the flexible terminals is held there untiliaiter the disk h has passed by the contacting points on flexible terminals 71 and Tr. The pin h carried by stem H having reached the top of the slot provided inthe insulated disk 72?, kicks or draws out the disk 705 from its temporary position, and upon the full return of the stein'H to its normal position the disk h is withdrawn to its normal position and the flexible terminals are permitted to return to theirfnormal positions, so as to perform the same function upon next depressing the key When the key or stem H-IS fully de pressed, the break is made, and precisely the same result is obtained .as by construction shown in Figs.- 6 and. 7.- It s .to be understood that the insulating-disk h? is slightly broader than the stationary contacting disks h s and h being slidably mounted on the stem-H by reason of a slot transverse of the disk and a pin it in-the stem and working in .the slot of slidable. disk h The position of and the disk h will at the proper time force t5.

the fiexibleterminal away from the disk 'h so tha'twhen the key and stem H are retracted by their spring h the insulating-disk will be retainedby its engagement with the" two flexible terminals until the conductingdisk h shall have passed. 'It is at this point wvhere'the pin in the stem withdraws the :in-

sulating-disk upward and away from the flexible terminals, as already described. The

insulating-disk it has a' sliding movement on the stem H by'reason of a pin it" in the stem ."workingin'la slot in the disk. Hence when the keyiisretracted byits spring h the insulating-disk will be retained by its engagement .with the two flexible terminals until'the controns on these terminals, whereupon the menducting-disk k shallhave passed the projeclating-disk will be drawn upward again. Thus thereiwill be no closure 01" either of the circuits on the return movement of this key.

In the modification shown in Fig. 9 the key-stem K carries a conducting-disk k that in its downward movement first contacts with the projection on the flexible termina'l'lfi, closing the circuit through the selectmg-magnet. A further movement causes the pm Ye to actonthe insulated lever is to bear against the portion W of the terminal .16 thus breaking the circuit thorugh the terther movement of. the key-stem willcause a.

v ,minal, and then the disk lctcqntacts wi h a projection on the terminal 76*, closing the circuit, through the power-magnet. The fur;-

in kl on the key-stenato strike an insulatingever k which latter will strike the flexible terminali7c and move it out of range of the disk 7: cutting out the power-magnet. N ow when this key stemfisret'urned by its spring k the insulating-levers kand it will not be at. once moved, but will retain the flexible terminals with their projections out of en-- gagingposition with the disk 1: until the latter shall have passed beyond these projections. .Thereupon a pin It will strike the lever lc and cause it to release the terminal k At the same time a pin l will strike the insulating-lever.lc and cause it to release the terminal k Thus there is no contact'of;

I the terminalso'n their return stroke. if"

Another modification of key is in Fig; 10, in which the key-stem M has -a bev- 'eled portion m and at the lower end a head When the key is depressed, the face m? m will strike an offset m on a flexible terminal m thereby energizing a selecting-magnet. .A 'rther mdvement of the stem will cause a pi t on the'stem tostrike and move the ar.=. m of a bent lever of insulating material,

which arm m will strike an offset m and move the blade 'm away from the face m Simultaneously therewith the head m will engage a flexible blade m thereby cutting out the selecting-magnet and energizing the power.magnet. .A further movement of the,

key-stem will cause the arm m of the bent lever to strike the portion m of the blade m and move it away from the head m there byopening the circuit of the power-magnet Now the arms of the bent lever will engage the blades, so that thereis an end thrust that will serve to retain these members inthis position with all the terminals separated.

Upon the key being released the spring m will return the stem; but the blades will be both held out of engagement with the stem 'until the head and beveled face have moved stem, whereupon a pin m will strike thearm= m of the bent lever and move this lever back -to its normal position releasing the terminal blades. v

In the modification shown in Fig. 11 the stem N carries a metal plate n On a plate N X are pivoted terminals N N that have connected therewith springs a 12, respectively. The other ends of these springs are connected to an insulated extension N of the stem N. When the key is depressed, the plate n first makes contact with the lever N x thus energizing the selecting-magnet. 'Thereupon the plate makes contact with the other terminal N thereby energizing the power-magnet. A slightly further depression of the insulated extension N 9 causes it to relieve the tension on the springs n n,towhich it is connecte and when the stress of. the springs against'f the-levers N 3 N is removed these levers will fly away from the plate n and against the stop-pins n n, and thus; being out of contact with the plate ah the circuitxis each ofthe springs there will be an outward movement of the terminals N N, carry ing with them the other ends of these sprin s a 3n, andthus the line of draft or-pullo the spring is carriedbeyond the'pivotal eenterof the terminals, so that the-tendency of these springs is to withdraw the terminals-from contact with their plate n Then they are held in this withdrawn position until, by the returning of. the stemto-nearly its normal plate 92 out of reach of the terminals before the line ofdraft of the springs again passes the pivotal centers of the terminals N N? and returns them to their normal position.

Referring now particularly to Figs. 17 and 18 of the drawings, showing the type-shifting means, a semiring' P is rigidly connected with a curved type-head-shifting bar p by rods 7) p. A shaft p is rotatably mounted in the frame and extends from side to side: On this shaft is secured a pair of arms 11* p that are pivotally connected with armsp p which in turn are pivotally connected with parallel links a a, similar to links a a The semiring P is rigidlycomected, by means of arms 30 with the vertical: arms 10 Hence when. this shaft p is rocked it will raise and lower-the semiring, the latter being guided in brackets 12-. On. the shaft p are rigidly secured arms 1." r? A pair of levers 1 r is mounted on a short shaft 1 secured. to the side of the machine. Each of these leverscarries a pin 1 1*, that engage, respectively, forked portions at the extremities of the levers 1" r Hencewhen the shaft p is rocked the levers-1* T will be rocked also. On the top: of the machine is mounted an electro magnet S, that serves to rock an armature.

lever s that is pivotally mounted on. the said top. This lever has a slot 5-,. in which slides its pivotal. pin s", and a retractil'e' spring 8 tends to move the lever upward for the limit of this slot The lower extremity of the armature lever has. a foot or offset s, that, when the armature is attracted by its magnet, will be rockedv againstthetension of said spring and be drawn immediately under the universal power-bar B. On the lower por tion of this armature-lever is a pin 8", that rides in aslot 8 in the lever 1*, which slot is shaped as shown. Another electromagnet s is mounted alongside of the electromagnet S has an armature s, which is mounted on an armature-lever a. similarly to the armature .9, said lever carrying a pin 8 on its lowero'fiset extremity s The latter pinv engages a slot in the lever r The operation of the type-shift parts is as follows: VVl-ien themagnet S is energized, it will rock its armature-leverand move the foot s under the power-bar B. New upon the power-magnet D being energized its armature ahd connected levers will draw the powerbar downward, which will strike the foot ofthe armature-leverand carry it downward.

This latter movement will cause the pin 8 on the armature-lever to rock the lever r, and hence the shaft p which latter will raise the shitt ng-bar P for a certain distance, which may be its full range of movement, and when released the retractile springs will return the parts to their former positions Now when the other magnets is energized it will operate in the same manner as just described;

saunas but. the armature -lever' 8 is so constructed that its foot will not be engaged by the powerward. Consequently the semiring P will be raised only for a part of its full range of movement, which may be one-half by proper adjustment of the armature-lever.

In order to retain the shift member P and its operating parts in either of the positions to which shifted, I provide a segment-arm t, secured to the shaft p which segment has notches t 25 A bent lever t has a lug t, that is caused to engage these notches by a spring t when the shaft has been rocked to its said respective positions. The lever t carries an armature ththat is attracted by anelectro magnet i This latter, when energized, will serve to move the lever out of itsnotch in the segment-bar, and thereby release the shaft p permitting the parts to return to their normal positions.

It willv be observed that the slot 8 in the lever 7* has a notched portion at which the pin 8 on the armature-lever normally lies.

The efliect of this isthat when the other armadraw the armature-lever a downward. It

will also be noticed that the lever 1* has its slot shaped with-the same enlargement, for similar reasons. Hence when the lever 3- 1S drawn. downward the lever T will not. di'aw.

its engagin armature downward.

While- I lave shown and described my invention as applied to a typewriter for operating a type-bar to cause it to move to the printing position and also as applied for effecting shifting of: the type-head to position one of a plurality of type characters.

thereon, yet it is to be understood that it has application for effecting shifting of the ribbon mechanism to move the ribbon pat-hwlse and for effecting reversal of the ribbon traverse furthermore, for effecting return'of the carriage to the starting-point; for effecting return or movement of the type-carriage frame, as for line-spacing, and for effecting movement or operation. of such other parts of the machine as may be desirable The important and desirable and intended purpose of the construction characterizing this invention. is the avoidance of the creation of a multiple circuit when the" terminal arms in the form of construction illustrated in Figs. 1 to 7, inclusive, is in the course of its movement while in contact,.first, with theterminal f and then with: the terminal'f. In this respect particularly my invention is distinguished and difierentiated from the present art. The result referred to is described by isolating the selecting-magnets and their respective circuits from the operating or.

- work magnet and its circuit. It will be Whereas the work or operating magn'et is' readily understood that the selecting-magnets by reason of their required number and location must necessarily be very small,

preferably much larger, so that it will develop the requisite power to efi'ect movement of the movable or selected a type-bar, &c, It is obvious that to produce a resistance equal to that ofthe work or operating magnet, as for permitting the selecting and Work magnet to Work in multiple circuit, the wiring on these selecting-magnets would necessarily be of such fine gage (by net.

reason of the limited space permissible for disposing such magnets) that such wiring wouldfuse under the action of a current like that utilized to energize the work-inag- My invention may also be used in situations other than in type-writing machines, as in linotype-machines and the like.

Without limiting myself to the construction and arrangement of parts hereinbefore set forth, what I claim new, and desire to secure by Letters Patent, is

1. In an electrical typewriter, the combination with a series of movable members,

, and a source of electriccurrent, of a universal power-bar, actuating means therefor, se-' lective devices associated with the several movable-members, and a selective operating device for each member constructed suc- .cessively to complete the circuit from said source to energize the corresponding selective device and then to switch the current to energize the poWer-bar-actuating means. 2.
