SPECIFICATION forming part of Letters Patent No. 657,478, dated September 4, 1900.

Application filed June 30, I898 To all whom it may concern.-

Be itknow'n that I, THADDEUSOAHILL, a citizen of the United States, residing at Washington, in the District of Columbia, have in vented. certain new and useful Improvements' in Type- Writing Machines, Linotype-Machines, Type Sjetting Machines, or other Keyboard Printing Instrumentalities, of which the following is a specification.

Certain features of my invention are designed for use in typefwriting machines, linotype-machines, type-setting. machines, and other keyboard printing instrumentalities in which letters are produced (printed or selected) by operating upon keys, while. other features of my invention are peculiar to type-writing machines. I shall first describe myinvention as applied to a type-writing machine and will then point out how certain important features of my invention may be applied to linotype-machines, typesetting machines, and other keyboard printing instrumentalities.

As applied to a type-writing machine the objects of my invention are to make a typewriting machine in which the operator can depress a plurality of keys in succession to make successive letters without having to release the key first depressed befored'epressing the next key. Intype-writing machines as ordinarily constructed it is necessary, it should be understood, to release one key before another key can be depressed to make another letter. This necessitatesan abrupt or staccato touch on the part of the operator in which each movement is made by in itself. In playing apianaforte, on theother hand, or an organ with the usual legato touch there is none of this abruptness. One movement overlaps another. The finger which has just depressed a key is rising while another finger is depressing another key to produce the next note. By reason of this overlapping of the movements this fact that several movements in difierent phases are taking place at the same Lime-performers can play scales and produce other effects on a pianoforte, as is well known, with the most remarkable rapidity. The touch in which one movement overlaps another, in which one key begins to Serial No; 684,880. (Np modal.)

descend before the preceding key has been released, is commonly termed by musicians (forreasons which Ineed not go into here) the legato-touch. A principal object of mypresent invention is toenable the operator to use a legato or overlapping touch in depressing the keys of a type-writer--that is to say, to depress a key before he has released or while he is releasing the last key depressed-and to obtain proper printing. By doing this I make the operating easier and more natural and at the same time materially increase the speed, for in type-writing machines as ordinarily constructed the limit of rapidity of action is the time in which the operator can both depress and release the key, while by my invention the limit of rapidity of action is the time in which the operator can depress the key. He does not need to release it before he depresses another.

The features of my invention above referred to by which the operator is enabled to depress a key without waiting to release the key or keys previously depressed may be applied to type-setting and linotype-machines as well as to type-Writing machines. The remaining features of my invention are specially applicable to type-writing machines; and it consists in certain features of construction hereinafter described by which a typewriting machine of simple and durable constru'ction is made adapted to Write letters one at a time and having a few keys acting singly and in different combinations to control a much larger number of characters.

I shall first describe a novel form of typewriting machine (illustrated in Figures 1 to .14. of the accompanying drawings) in which my invention is embodied. After that I shall illustrate certain features of myinvention as applied to certain other forms of type-writing 9o machines. Then I shall illustrate the application of my invention to a linotype-machine, and, finally, I shall point out and specifically claim the parts, improvements, and combinations in which the invention consists.

The machine illustrated iu.Figs.. l to 1'4, i'nclusive, resemblesin many ways the machine. illustrated in a pending application. of mine, Serial No. 668,737, filed February 1,1898; but

the machineill nstrated inFigs. 1 to; 14 of? thepresent application. d-ilfers from the machine illustrated inthe pending application. beforesaid, (a); in that it" is constructed to write l'ett'ersone' at a time only, while the machine illustrated'in the applicationof 'F'ebrua'ry 1, 1898, aforesaid is adapted". to write" letter-sin pairs, (6) in that it i's'c'onstructe'd toenable' the operator to-depress' a key to makea letter without having first to release the" key or'key sd'epressed to make the preceding, letter, and ("c) in various other particulars, the most important of are pointed out in the statement of claim atthe end'hereof'.

The machine shown in Figs. 1,t014 of the accompanying drawings in illustration of my inventionconsists, essentially, of (a) a set of l typeebarslsuitably-mountedand sttil-ing to a 1 trolled; by said; keys actingsin glyand in diffene.nt,-combinations,,whereby the type-bars aforesaid are connected,each as required, with the motor device aforesaid and said motor idevice. brought into action to impel thet'ype- 'fbar' thus connected with it; (a) means con- :nectedwith andi actuated bythemotor, de- .viceafo'resaid,,whereby said motor device as the. type-bar. approaches.v the printing point' c uts;off" the power from, i t's'elf'an d" releases the lvario'us'parts.controlled by the key, so that the type-bar'witli; the; other parts controlled ghy the key,inc1'uding the motor device itself, *can resume. their normal" positions, whereby the operator is enabled to" depress another key'to makeanotjher letter without having ?to wait torel'ea'se the lieyfirst depressed, and (f)'a-paper'-carriage, spacing mechani'sm,rib-

iwhich beingoldand' well known l need not Themathframe-The main frame of the gin'a'chinezfi'gured in the drawings consists, es- ;jsentiall'y', of (11) a bed pl'ate 1', ('b)'a top plate ,2, (1c).a center ring 4'0, (d) standards 41 41', bolted to" the bed-plate andservin g to support the center ringylJO, the group-controlling l'evers; the bell-crank levers, the motor-frame, the circnitclosing] frame, the pin carrierdriving fi'ame the normal frame, and'various other parts hereinafterdescribed, ,and(e)' four coin urns 424242 42', which rise from the center ri'ng' tOto support the t0p'plate2;

The type-Bars and'the meansfor controlling .them.--50i50' are the type-bars mounted" by 'means of hangers'5'1 51 in the usual fashion. -A few type-bars only are shown in the drawings, but any convenient number may of coursebe used. The machine figu'retl in the Underneath the inner ends of' the radial] IIO levers 52 52 are the pins 60, (one pin to every four radial levers as the machine illustrated in the drawings is constructed,) mounted in the oscillating pin-carrier 61 and held in their normal positions (shown in Figs 1, 2, and 12) by light expansive springs 62 62, which bear upon collars 63 63, attached to the pins 60 60, forcing said collars down on the lower disk of the pin-carrier. Each of the pins 60 60 serves to give movement to the different radial levers of the group controlled by it, each as required, the pin-carrier 61 being oscillatedto bring the pins into operative relation with the different radial levers controlled by them, each as required.

Just below the pins 60 60 are the groupcontrolling levers 65 65, which are centered on rods 66 66, supported in the standards 4141, said standards being milled to produce slots to receive the several group-controlling levers aforesaid. The proximate ends of the group-controlling levers 65 65 are made segmental, as illustratedin Figs. 5 and 8, so that however the pin-carrier 61 may be vibrated each of the pins 60 6O always lies over the corresponding group-controlling lever 65. Tilting pieces 67 67 are hinged to the groupcontrollinglevers 65 65. An oscillating frame 70 underlies said tilting pieces. Said oscillating frame is mounted by means of the arm 71 of the rock-shaft 72 and a bridle-lever 73, to both of which it is pin-jointed. To the other arm 74 of the rock-shaft 72 the armature 75 is connected. Said armature 75 and the core 76 (which is attached to a plate 77, that is bolted to the bottom of the bed-plate 1) lie within a non ferruginous tube 78, around which the energizing-coil 79 is wound. The magnet thus formed serves to give movement to the oscillating frame 70 aforesaid, and thereby'to whatever one of the groupcontrolling levers 65 65 may have its tilting piece 67 67 overlying said frame. A tilting piece 67, hinged to one of the group-control- I ling levers 65, normally overlies the motorframe 70, while all the other tilting pieces 67 67 lie out of the path of movement of said oscillating motor-frame.

We have seen that each of the group-controlling levers 65 65, with the corresponding pin 60, control a different group of the radial levers 52 and type-bars 50. The question then of what type-bar shall be impelled when the oscillating frame 70 strikes up depends upon (a)-what one of the group-controlling levers 65 has its tilting piece in the path of movement of the motor-frame 70, and (7)) what position the vibratory pin-carrier occupies, whether its normal position or some one of the positions into which it is moved re spectively by the depressing of the keys B, B and B To control the nine tilting pieces 67 67, there are nine keys C 0, each of which. serves, as we shall soon see, when depressed to swing the tilting piece 67 connected with the group -controlling lever 65 that corre-.

sponds to such key over the oscillating frame rangement of the keys and the parts which they actuate.

The keys B, B and B controlling the pincarrier 61, are designed to be operated ordinarily and properly by the thumb, while the" nine keys C 0, corresponding to and controlling the diiferent group-controlling levers 65 65, are designed to be regularly and properly operated by the fingers. The space-key G is designed to be operated by the ring-finger.

Overlying the keys B, B and B (J C C,and the space-key G is a set of key-corresponding and key-actuated levers (which, for greater convenience and to distinguish them from the key-levers, I shall sometimes hereinafter term key-actuated levers or key-corresponding levers) b 11 b 0 c c, and g. These levers are f ulcrumed in front by means of a rod 80, which is set in the bar 81. Said bar is milled to receive the key-actuated levers aforesaid. It serves as a stop to limit the upward movement of the keys, and it is attached by screws 82 82 to lugs 83 83, that rise from the bed-plate 1.

To the rear end of each of the key-actuated levers b b b 0 cc, and g is hinged a releaser-arm 84, which is held by a contractile spring 85 normally in contact with the lug 86 on the metal end piece 87, attached to the rear end of the corresponding key-lever. (See Figs. 1, 3, and 4.) The releaser-arms 84 84 aforesaid serve each to connect the key-actuated lever to which it is attached with the corresponding key-lever (B, B or B C G G, or G,) so that when said key-lever is depressed in front by the operator it rises back of the fulcrum and lifts the corresponding key-actuated lever through the releaser-arm 84; but about the instant the type-bar strikes to print-say, preferably, when the type-bar has moved about one-fourth to one-third or even less of the distance from its normal position to the printing-center-the releasing-frame 90, which is centered at 91 and connected by the link 92 with the arm 93 of the magnetactuated rock-shaft, strikes the releaser-arm 84, moving it off of the end piece 87, connected with the key-lever, and allowing all the parts to return instantly to their normal positions and before the operator has released connected by links 97 97 with the tilting .4 v mars pieces 67 67, serve toconnec't the key-actuI-' when depressed lifts, through the releaser arm 84, the corresponding key-actuated lever 0, which serves (a) to swing, through its bell-crank 95 and link 97, the tilting piece 67 connected with the corresponding groupcontrolling lever over the oscillating mo,- tor-frame to receive movement therefrom; (b) to lift the normal frame 140, centered at 141 and which acts on one of'the bell-cranks 95 aforesaid and through such bell-crankand the link 97 connected therewith swingsthe normal tilting piece 67 ofi from over the 1 motor-frame 7'0, and (c) to lift the circuit-- closing frame 150, centered at 151 and having an arm 152, carrying the battery-connected spring 153, pressing said battery-connected spring over against the contact-screw 1541, (to.

which one end of the magnet-coil 79 is connected, theother end of said coil being connected with the battery, asshown in Fig. 4,)

thereby closing the circuit of the magnet be-.

fore described, so that the core 76 attractsthe armature 75, which thereupon lifts the motor.- frame 70, thereby giving movement to what-; ever one of-the tilting pieces 67 overlies it and to the group-controlling lever 65 to'which said tilting piece isconnected and to the pin 60 overlying said group-controlling lever. Said pin in turn gives movement to Whatever one of the radial levers 52 52 it underlies, and the radial lever thus moved gives movement through the link 56 to the corresponding type-bar 50, throwing the type up against the printing-point. As the type-bar approaches the printing ,point the releasing-frame 9O (centered, as before said, at 91 and connected by the link 92 with the arm 93 of the magnetactuated rock-shaft 72) strikes the releaserarm 84, movingit off of the end piece 87, attached to the corresponding key-lever. Thereupon the key-actuated lever returns to its normal position, releasing the various parts controlled by it and, among others, releasing the circuit-closing frame 150, which, returning to its normal position, breaks the circuitof the motor-magnet aforesaid, whereupon the armature 75, with the oscillating frame 70, return to their normal positions under the influence of the contractile spring 160, releasing the tilting piece 67, group-controlling lever 65, pin 60, radial lever 52, and type-bar 50, all of which immediately return to theirnormal positions, being assisted thereto by suitable springs, some of which are the handas distinguished from the thumb we may properlyterm finger-keys or fingerkey levers) serves when depressed to cause some one of the type-bars of the group corresponding to itto be actuated by the oscillating motor-frame 70, and if no one of the keys B, B and B (which from the fact that they are designed to be normally and regularly depressed'by' the thumb we may term thumbkeys or thumb-key levers).is at the same time depressed that one of the type-bars of the group is actuated whose radial lever 52 over- .lies the corresponding pin 60, when the pinc arr;ier 61 is in its normal position, with the stop 180 attached to it, held in contact with the lug 184 of. the stop 182 by the contractile spring 183. The keys B, B and B serve to oscillate the pin-carrier 61 and thereby to control what one of the type-bars of a group shall be actuated. For this purpose a pincarrier-driving frame is used, consisting of (a) rock-shaft 170; ((9) three driving-arms 171,

from each other in the pin-carrier'6l, and

each of them controls a group of, four of the radial levers 52 52 and type-bars 5050. Each pin, as before said, in all its different positions overlies the corresponding group-controlling levers 65. Each pin normally underlies the firstradial lever 52 of the group of radial levers controlled by it, and it is oscillated to underlie the second, third, and fourth radial levers of its group, respectively, by dedepressing the keys B, B and B respectively. Thus if the key B be depressed said key gives movement through the releaser-arm 84 to the corresponding key-actuated lever b, which lifts the stop 17 9, carried by it, up into the path of movement of the corresponding adjustment-screw 178, carried by the stoparm 177, and at the same time said key-actu ated lever bacts, through the push-piece 174, pivoted to it, upon the arm 171 of the rockshaft 170, moving said rock-shaft in the direction of the arrow, Fig. 1, and through the arm 175 and link 176 moves the pin-carrier61 in ,the direction of the arrow, Figs. 7 and 11, so bringing each of the pins 60 60 into operative relation with the second radial lever (counting in the direction of the arrow, Fig. 7) of the group of radial levers 52 52, controlled by it, in which position all the parts are arrested by one of the adjustment-screws 178,

carried by the stop-arm 177, coming in contact with the stop 17 9, carried by the key-actuated lever b. If the key B be depressed, the corresponding key-actuated lever (7 act- IIO ing in like manner through its push-piece 17 1: upon the arm 172 of the rock-shat't170, moves the pin-carrier 61 until each of the pins 60 60 underlies the third radial lever of the group controlled by it, in which position all the parts are arrested by one of the adjustment-screws 178, carried by the stop-arm 177, coming in contact with the stop 179, carried by the keyactuated lever 11*. If the key-lever B be depressed, the key-actuated lever 17 corresponding to and controlled by it acts through 5 its pivoted push-piece 174 upon the arm 173- of the rock-shaft 170 and through said rockshaft and its arm 175 and the link 176moves; the pin-carrier 61 in the direction of the ar-} row, Fig. 7, until the pins 60 60 each under-i lies the fourth one of the radial levers 52 52 l of thegroup controlled by it, in which posi-j tion all the parts are arrested by the stop 180, which is attached to the pincarrier 61, coming in contact with the lug 181 of the stop} 182, which stop is screwed fast to the lowerl surface of the center ring 40. When the coni nection between the thumb-key lever B, B or B is depressed and the corresponding key- 5 actuated lever 1), b or b is broken by thel action of the motor-impelled releasing-frame 90 upon the releasing-arm 84, the pin-carrier i 61 and the parts connected therewith are returned by the contractile spring 183 to their normal positions, with the stop 180, carried by the pin-carrier 61, resting against the lug 184 of the stop 182. The pin-carrier 61 is mounted upon an axle 185, set in the cap-ring 55, on which axle it is held by the collar 186 and a set-screw. (Not shown in the drawings.)

To prevent the motor-magnet from acting to give movement to the oscillating frame while the pin-carrier 61 is taking position, there is a frame 190, Figs. 1 and 4:, centered at 191 and lying underneath the keys B, B and B so that it is depressed by said keys when acted on by the operator. The frame 190, Fig. 4c, is connected through the spacemagnet H with one pole of the battery, and it makes connection when in its normal position with the spring 192, which is connected with the coil 79 of the motor-magnet. When any of the keys B, B or B is depressed, the '1 frame 190 impelled thereby moves away from the spring 192, breaking connection therewith; but as the key impelling said frame ap- I proaches the limit of its movement said frame 1 comes in contact and makes connection with the spring 193, likewise connected with the coil 79. The frame 190 then, with the springs 192 and 193, serves, it will be seen, (a) to establish connection between the battery and i the coil 79 of the motor-magnet when the keys 1 B, B and B are all of them in their normal 1 positions, (1)) to break this connection so soon as any one of said keys begins to be depressed and to keep it broken while said key is be 9 ing depressed and the carrier 61 positioned, and (c) to reestablish the connection as soon as the key B, B or B depressed reaches whatever may be used.

the limit of its movement and the pin-carrier comes'to rest. By this construction the oscillating frame '70 is prevented from striking to impel a type-bar while the pin carrier 61 is moving into position.

The shift-key, Figs. 1 and 5, is marked 195. It is attached by a stem 199 to the frame 196, which isfulcrumed at 197 and connected at 198 by a pull-down wire (not shown in the drawings) with one of the bell-cranks carrying the shift-rod (not shown in the drawings) at the top of the machine, by which the platen is shifted, and which being old and well known in the art and forming no part of my invention I need not describe here.

The carriage, the ribbon mechanism, the interlinear-spacing mechanism, the alarm-' bell, and other usual details may be of any suitable kind, and as many forms of such devices are well known in the art and as they constitute no part of my invention 1 have not thought it best to illustrate them in the drawings or to burden this specification with any description of them.

Any suitable form of spacing mechanism I prefer, however, to use a spacing mechanism suchin principle as those illustrated in a number of prior patents to me, such as the patent of August 8, 1893, No. 502,700, and that of March 1, 1898, No. 600,119, consisting, essentially, of (a) a rack 0 Fig. 14:, suitably connected with the paper-carriage, which latter is urged in the direction of the arrow, Fig. 14, by the usual carriage-motor-spring device (not shown in the drawings) or by any other suitable means; (19) the fast dog H and the loose dog H (0) the dog-carrying lever H, by which said dogs are vibrated into alternate engagement with the rack e aforesaid; (d) a normal stop H serving, ordinarily, to limit the movement which the loose dog H executes under the influence of its contractile spring H when withdrawn from the rack 0 to a single toothspace of said rack; (e) a space-enlarging lever H to which said normal stop H is attached, and whereby said normal stop is lifted when the space-key G is depressed from its normal position, thereby permitting the loose dog H when freed from the rack c an increased movement until it is arrested by the stop H attached to the bridle-lever H and (f) means for actuating the dog-carrying lever H.

The key-actuated lever upon which the space-key G acts through the releaser-arm 84, is connected with the space-enlarginglever H by a push-up H so that whenever the space-key G is depressed it acts through the releaser-arm 84, lever g, pushup H, and space-enlarging lever H to lift the stop H thereby to permit an increased movement of the dog H spacerack c, and paper-carriage connected therewith.

H H are hangers, and H H are stops, Fig. 14, and H is the returning-spring for the dog-carrying lever H.

, To give movement to the lever H and the i by a link with the-lever.H).or in any other suitexample, by connecting the lower part of the motor-frame 70 to the front end of a lever of dogs "connected thereto, I may use either (a) a space-magnet H which may be either in otherwise to actuate the dog-carrying lever ularly in those" machines in which a large itype-bar-impelliug electromagnet, or (b) in series with the, motor-magnet, as shown diagrammatically in Fig. 9, or in parallel with it and connected through the lever H or H, or (b) I might connect the key-actuating levers to actuate the dog-carrying lever H through the circuit-closing frame 150 (to which an arm might be attached, connected able manner, or, (0,) which is better than'the last, 1 may connect the motor-magnet by its armature 75 to actuate said dog marrying lever H in anyconvenient manner.'as,'for

Instead of operating the releasing-frame 90 by the same electromagnet which actuates the type-bars itinay, if desired, particparallel with it, or (c) the electrom-agnet actuating the releasing-frame 90 may be placed in series with the type-bar-impelling' electromagnet. v i

Iprefer to actuate thereleasing-frame 90 or its-equivalent by a motor, and the combination of such frame with a motor. for 210- l tuating it and with other elements of the mechanism constitute important features of my invention ,-but in any paragraph of claim at the end hereof in w-hicha releaser or a releasing-frame'is made an element and in which no reference is made to a motoractuating said releaser or releasing-frame I do not in such claim limit myself to actuating said releaser or releasing-fraine'by a motor,

for, in fact, while it is very advantageousto actuate it by a motor it is not absolutelyine dispensable that it be so actuated.

At the same time a parallel=cii cuit is closed, as fully described in the pending application aforesaid, through the releasing-magnet B The arrangement (of the circuit is or may be that fully described in-the pending application aforesaid with reference to Fig. 1 or Fig. l thereof. for that portion of the structure illustrated in Fig. 15, which is old in this application, being fully described in the Letters Patent aforesaid, No. 604,001. C O are the key-levers, to each of which the releaser-arm 84 is pivoted in front at 111, said releaser-arm having a projection 84 formed thereon to be struck in due time when the'key is depressed by the releasing-frame 90, centered at 91. To the releasing-frame 90 is attached an arm B carrying an armature'100, which lies in the fieldof the electi'ornagnet B A'contractile spring 815 holds the releasing-frame in its normalposition with the platinum contactpoint'carried by its arm-B resting against andmaking connection with a similar contact-point in the adj ustmen't-screw 13 The electrical connections of the contact-screw B, the arm B and the electromagnet B are the same as those of the similarly-marked parts mine drawings of the Letters Patent aforesaid, No. 604,001, which being fully described in the specification of said Letters So much Patent need not be further described here.

1 To the motor-frame E is attached an extension 120, to which is connected a push-piece 121, held in place by guides 122 122. Said push-piece serves, as the type-bar impelled by the motor-magnet E approaches its printing-point, to strike the releasing-frame 90, moving the arm B away from the contactscrew B thereby rupturing the circuit of the motor-magnet E and permitting the typebar to return instantlyto its normal position. lmmediatelyafter thus breaking the circuit of the motor-magnet E the releasing-frame 90, acting on the releasing-arm 84:, releases the key-corresponding lever c, the normal frame 0, and the circuit-closing frame 18 (both of which are fully described in the Lettiers Patent aforesaid) controlled thereby, thereby permitting all the parts to return to their normal positions.

In thefdevice of Fig. it will be observed the circuit is broken first when the push-piece 121 strikes the releasing-frame 90 by the arm B of said frame moving away from the contact-screw B", with which it is normally in connection, before the key-actuated lever 0, being released by the knocking out of the releaser-arm 84 by the frame 90, allows the circuit-closing frame 1 8to return to its normal position, and, further, if foranyreason as, for example, when the operator strikes two keys at once, so that the type-bars are locked on each other and unable to reach the printing-point, thereby blocking the motorframe E and pushpiece 12land preventing them from executing their normal move ments-the releasing-frame 90 is not moved in due time by the motor-magnet E the magnet B, which is adjusted in any of the ways known to electricianssuch, for example, as those referred to in the Letters Patent aforesaid, No. 604:,001to besomewhat slower acting than the motor-magnet E attracting the armature 100, attached to the arm B of the releasing-frame 90, gives movement to said arm and frame, producing the effects above described that is, breaking the circuit of the electromaguets and releasing the keycorresponding lever cwhereby all the parts are left free to return-to their normal positions whether the key 0 depressed be released or not and whereby the operator is left free to put down asecond key before he has released the first.

In Fig. 16 only so much of the well-known linotype structure is shown as is necessary to illustrate the manner of ap' plying my present improvementthereto, the assembling devices, whereby the matrices when released are carried to the assemblingblock and arranged into a line thereon, the devices whereby the space-wedges are inserted and the justification effected, the devices whereby the slug is cast, trimmed, and arranged in the galley, the distributing mechanism, and other necessary parts of the ma chine,- which are already well known in the art and fully described in divers well-known United States patents to Mergenthaler, particularly that of September 16, 1890, No. 436,532, aforesaid, being omitted Instead of using electromagnetic motor mechanism to impel the type-bars pneumatic or other suitable motor mechanism may be ,be connected to be actuated by the frame 150,

(See the specification of the said Letters Patent, in which it is pointed out that such a frame may be used to control other motor mechanism than electromagnetic mechanism.)

Insteadof using a single electromagnet or other motor device to impel all the type-bars obviously a different electromagnet or other motor device might be used for each different group of typebars, as in the construction fully lCO set forth in the Letters Patent aforesaid, No.

Oneiinportant advantage of ,t-hisfeature of myinvention isthe mechanical type bar-controlling devices of the kind desimplicity which'it gives to the device, as the tage lies in the fact thatthev releasing is not ef- I fect eduntil an instant of timeafterthekey, whereby another-keymayfbe depressed to print while the key firstdepressed is still held down,"has been depressed, thusflea'ving time for the motor mechanism called-into-action .by the-depressing of} the key to operate;,.. I'am not aware'that any part'operating-in thi's man- 'nerhassever beenu'sedlin a type-writing machine. The part serving-for this purpose in the structure illustrated in the drawings is the releasing-frame 90,i np'elled byfithe motor-magnet 79 .but obviouslysomeotherpart than the releasing-frame 190,,i'm p'el'led, -ifir desired, in (some other :mannerthanbyirneans' of an electromagnet, may be used instead of said releasing-frame tlO' a'nd magnet-n9 toeffec'tthe releasing; 1 y v v (1)) Another important-feature ofimyinven- ,tion (and one-which, so faras l am zin-forme'd,

- is broadly new with me); consists in combining motormechanis'm (preferably motor mech anism which is normally stationary,jbut which actswhen akeyis depressed) for impelling the type-barsorother parts .controlled by the keys with. suitable; -re'leasing' mechanism, whereby-when a key'has bee epressed to printanot-herkey QftheQS'ameset' may be depressed toprintbefore the key first depressed is-released. By this-means the touch is made to; be veryplight indeed andthei'play of the keysis reduced,1sothat the operator is enabled to "use all the fingers-0t the hand; .evenj the weakest ones,"readily: uponthe Ikeys, and

erating the releasing mechanism by power other than that exerted uponthe key. Thus in the drawings the releasing-frame 90, which acts upon the releaser-arm 84, is operated by the magnet 79, Figs. 1 and 4; but obviouslysome other form of motor-operated releasing means might be used, and while I prefer to operate the releasing means by some form of motor device I do not, I wish it to be very distinctly understood, limit myself to the use of a motor device for releasing in any paragraph of claim in which a motor device or motor mechanism for releasing is not made by somesuitable form of'words an express element of the combination set forth in'such claim.

(d) Another important feature of myinvention (and one which, to'the best of my information, is broadly new with me) consists in the use of a single releasing device (whether it be a frame, as 90, or some other device) common to a plurality of latches or other releasable connections and serving to free such connections each as required. In the drawings as already described the common releasing-frame 90 serves to act positively upon all the releaser-arms 84 84 each as required, thereby to release all the levers c 0 Z) 17 b g 850., each as required; but while I consider it advantageous to use the same releasing-frame or other common releasing device to act upon all the releaser-arms 84 or their equivalents each as required ob-' viously within the broad principle of my invent-ion a releasing device may be used to release a plurality of arms 84 or their equivalents without being used to release the whole set of said arms. In other words, two or more releasing-frames might be used each acting upon a plurality of releaser-arms 84: each as required.

(6) Another important feature of myinvention consists in using a single releaser-arm, as S4, (or some equivalent part,) for a plurality of type-bars. The releaser-arm 84, it will be seen, controls mechanism which in turn actuates all the type-bars of a. group, each type-bar as required, all which, so far as I am informed, is broadly new with me.

(f) Another im port-antfeature of my invention (and one which, so far as I am informed, is broadly new with me) consists in releasing a motor-controlling device to permit the same to return toward its normal position in advance of the release of the key. In Figs. 1 to 14 the form of motor-controlling device illustrated is the frame 150, controlling the circuit of the electromagnet 97; but it will be understood that some other suitable form of motor and of motor-controlling device may be used, if desired, and, further, it will be understood that Within the broad principle of my invention in this regard the motor-controlling device may be released by releasing which impels the type-bar or other type-controlling device. One ad vantage of this is that the point in the travel of the type-bar or other type-controlling device at which the releasing is to be effected is readily controlled; but, as has been already clearly pointed out, a different motor device may be used to operate the releasing device from the motor device or motor devices used to operate the type-bars, matrix-freeing escapement devices, or other type-controlling devices, whatever these may be. It will be understood, therefore, that when in any of the paragraphs of claim at the end hereof I speak in any form of words of a motor device or of motor mechanism for releasing without clearly expressing in apt words that said motor device is the same motor device which impels a type-bar or the typebars that I do notlimit myself to the construction in which the motor that releases is also the type-bar-impelling motor.

(h) It has been proposed heretofore (see, for example, the patent to Flower, No. 426,931,

dated April 29, 1890, and the reissue of the same, No. 11,391, dated November 28, 1893,) to connect the key-lever and the corresponding type-bar together in such manner that when the trip is effected said key-lever and type-bar resume their initial positions simultaneously; but in my preferred construction illustrated in the drawings there is no connection between the key-lever, as B B B C O C, or the key-actuated levers, as 1), b b 0, c, c, and g, and the type-bars, whereby either the key-lever itself and the type-bar (or even the key-actuated lever and the typebar) are caused to resume their initial positions simultaneously, and, in fact, the key-actuated lever, having a very much less distance to travel than the type-bar to return to its initial position, would naturally resume its initial position before the type-bar could resume its initial position, and there are reasons also why it is preferable (but not indispensable) that the key-actuated levers should resume their initial position without being delayed until the type-bars resume their initial positions, and, in fact, I have found it advantageous in my machines to adjust things in such manner that the releasing-frame 90 strikes the releaser-arm 84 and efiects the release when the type-bar has moved, say, about one-third the distance (sometimes more and sometimes less) from its normal position to the printing-point, so that the key-actuated lever, as c, c, f, f*, or f sometimes actually resumes its initial position before they have even resulted in the production-of are typet'ar liaseveii coiniiie'nced its return movement'and longbefore-it,resnmes its'in drawings and all prior devicesot which I am;
