Application filed May 27, 1903, Serial lie. 153,963.

To all whom it may concern:

Be it known that I, GEORGE W, 1302mm c, a, citizen of 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 O crating Means; and I do hereby declare the showing to he a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same.

,The object of this invention is to provide an-irnproved means for operating rind control g the writing mechanism for electrically-operated type-writing machines, and is to be distinguishedfrom my copending aplication, filed of even date herewith, Serial 0. 158,962, therein the object is to provide a key mechenism that when depressed will first complete a circuit including a selectingmagnet and position a type-bar member and upon further depression was break said circult and simuitsneously close a circuit in cluding a universal power-bar, thereby causing a t p'e-bsr corresponding to the key do presse to be operated and print a character 77 In the present invention the object is to provide a key mechanism that will first complete a circuit including. a seiecting-msgnet andposition a t is-bar member and upon further depression will break the circuit.

en upon still further depression it will make a circuit including a magnet that will operate a type-bar which has boon positioned and cause it to printits character. lVhen member connected with thstype-bsr has been positioned, a suitable latch 18 caused to engage the. mcmlu-r connected with tho typo hm and retain it in position until engaged by the atusting-har.

Another object is to provide an improvcd form of kcy or switch for controlling and opcrating such electricallyand operating mechanism. V r

A further object is to provide a krymocls anism which will effects cycle of movement of operative parts as follows: first, electrical connection. with n selecting-magnet to attract.an-arrnsture-oarrying pawl or lever that is suitably fills-ruined and which is thrrebv positioned for furl-her operation; second, switching of the current from the said magnnisrmsnct e'r to shift the another to shift the ribbon pcratod solcctingi net to a second niagnet to effect electrical connection with a magnet to attract the armaturc of an actuating power device, during which latter movement the pawl or lever is engaged hy th'e power device, and tho operative parts (that head, a shifting actuator, or other 0 crating part of a type-writer) are operated or a desired purpose, and, third, to break the circuit in order to cause return of the said parts to normal positiom'ail upon the down movement of thckey.

A further object is to provide novel constructions sngi arrangements for effecting the-so operiitions.

A further object is to provide a key constructiofirrliich will when cooperating with an outside soiirce of power andwhen op stated perform sefeiiil notions-namely, select. operate, permit return of the operated parts ini'lejiendcntly of the release of the key. The same msy be em loyed to o crate thc typingsnd sscing anlih'ibbon-fcc ing mechtypo-hcsd, and and other fn'g' any desired Inechnnisnion the i i 'riot herohj ect is to provide a form of kev that will firsifenergize one-of a set of select iugmiagnstsythen upon a further movement ,vrili' cut out the'said magnet, and upon astill inrth'cr advance will energize a power-mag- ;not, and upon a still further advance will cut out'thcpower-magnet, and upon release of tho key it will return to its normal posi Lion without energizing of the magnets.

Vfith thcsc'obficts in view and others my invention comprohcnds the construction, as

mngomont, sud comhinstiol'l -of parts,

hereinafter described and claimed. 7 V

'ii'cferriug to the drawings reprcsesing nn apparatus elnbodying my invention, Figure '1 is a front porspelct V View, certain parts being omitted; Fi Q. 2 is s vertical section through thc midis oi'tlic machine. Fig. 3 is a sin'iiii 7 f a modification. r

In tiii sovornl vicws the characters of roicrencoiiidiciitc the some part.

In it fro-ms A n're secured fulcrum-rods a a, that. carry Isss'm a, respectivcl which lattor support bent lovers 0 a, one of the bent levers lining snpportcd by a link a and a; 1 1k a, preferably arranged in parallelism. When may he a typo-bar or a t c- ,7

psrts one of the bent levers a is depressed, it will rock a type-bar of through the medium of a lever 01 and connecting-links a" a i A universal power-bar B extends between the links a and a and is supported at each end by an arm I), pivoted to the side late of the machine. On each side of the 'nks a is pivoted an armature-lever c, carr ing an armature 0 arranged to be attracts by one of a series of elcctromagnets 0 carried on a bar c, of fiber or other suitable non-magnetic material. A retractile spring 0 serves normally to retain the armature-lever c in the position shown and awe from its operatingmagnet. The lower an of each of these armature-levers c has a hook-shaped foot or offset 0, that when the armature-lever is rocked through the influence of its controlling-magnet will be moved under the universal power-bar B; but when the magnet is again de'e'nergized the retractile spring will move the foot away from its position of engagement with the power-bar.

On the base-plate is mounted an electromagnet D,having, preferably, two coils cl (1 An armature (1* is suspended within range of the influence of the magnet D, bein pivoted on a bar (i that is carried b two levers d d", the latter being pivoted at 7 to the side of the machine. The levers d (1 each have an arm (1, that is pivoted to one of the arms I). A retractile spring d serves normally to retain the armature, the universal power-bar, and their connected parts in the position shown in the drawings and away from the electromagnet Consequently when the electromagnet D is energized the armature will be attracted and rock the levers d", the arms (I thereon, and then the pivoted arm 11 downward and also the universal power-bar B. New should any of the selecting-mag nets be energized, and thereby brin one of the feet 0 under the universal powerar, and thereupon the electromagnet Dis energized, the power-bar will engage the hook c in its downward movement, and thereby o erate the corresponding type bar throug the aforesaid connecting members.

In my said application filed of even date herewith the armature-lever is retained in position by the selecting-magnet until the operating-1nagnet moves the power-bar to engage the hook on the lever by reason of the form of switch there employed. In the present invention I provide a latch E, pivoted on ear-h of the links a? a and resting upon the armature. When any of the armatures is attracted by its magnet, the latch will fall and bring its notched part (2 back of the ar mature, and thereby retain the armaturelevcr with its foot underneath the powerbar; but when the link a and comics-ted parts are carried down by the power-bar a stationary rod 6 will strike the latch and arrest its movement, while the armature continuing to descend will cause the latter fo be discharged from the notched part of the atch.

For each of the selecting-magnets 0 there is a three-terminal switch, preferably such as shown. In an. insulatin -block F is a metal bushing f, in which sides a stem f having a key f A plate f carries the block F and also an insulating-block f that guides the end of the stem f, which latter has a coilspringf, that returns it when depressed. A spring-terminal f is secured to the block F and is connected by suitable conductor with one terminal of a power-bar-o crating magnet. Another spring-termina 8 is secured to the insulatin -block f and is connected by suitable con uctor with one pole of the selecting-magnet. The other pole of the selecting-magnet and also the other pole of the ower-ma net are connected by suitable con uctor wit one terminal of a source of electric current, such as a battery G. The other terminal of the battery is connected with the bushings f of all the keys.

When the key-stem is depressed a short distance, a cross-bar f a on the stem strikes a projection f on the terminal blade f there y completing the circuit including the battery and the selecting-magnet. This will cause the armature of the selecting-ma net to be rocked and bring the hook-shaped not of its lever under the ower-bar B. .At the same time th latch will under its own weight have fallen so as to cause its notched end e back of the armature, and thus hold the armature-lever with its foot under the powerbar. A further movement of t ke '-stem will position the cross-bar f 9 beyond t e pro jection of the terminal blade f thus cutting out the selecting-magnet and breaking the current; but the latch will not have become disenga ed from the armature which it is then he dihg, but will tend to retain the armature-lever with its hook under the power bar until disengaged therefrom in the manner already above described. Thereupon a further advancement of the key-stem will cause the bar f to strike a projection f on the terminal thus completing the circuit a second time, including the battery a second time and the power-bar magnet once or for first time,

which will cause the powersbar to operate the type-bar, as hereinbefore set forth. A further depression of the key-stem will cause a pin f on the key-stem'to move an insulating-leverf down and strike the bent end f of the terminal blade f and move this blade so that its projection f will be out of range of e gagement with tl e crossbar f breaking the circuit through. said terminal blade f and permitting ret.um'.t0 normal position of the operating partsindependcnt of return of key. At the "same time a pin f on the keyste m will .cause an insulatinglever f move the terminal blade f so barf impinges against the offset or petite:

the cross-bar shall have passed the projections, A Thereupon in the continuation of the upward movement of the key-stem the pins f" and f will strike the levers and raise them to their former. positions and at the same time release the terminal blades.

In Fig, 3 I have shown another form of de vice for effecting the retainin of the selectlug-pawl durin any possible interval in the action of switc ing from one circuit to the,

'ftien is different from that eonstitutin subject-matter of my aforementione other. In this construction the latehesfE and bar a are omitted and a permanentlymagnetized armature c is emplo ed and which is constructed ofa metal or al 0y, such as Russia iron, that will retain the magnet isrn induced in it by the engaging GlQCtIOIQEt net for a short period of time, suilicient for retaining it in proximit to the me not with its lever-foot underneat the powerar until the latter shall be actuated by its magnet and enga e this foot and draw the lever downwar and thus remove the face of the armature from the field of attraction, as by drawin it down beond the face of the magnet, wl ich may, i desirable, be provided with a roiecting face of suitable dimensions. U on tlle release of the power-bar the retracti e s ring will withdrew the armature from the e ectromagnet'.

The depression by the operator of the means (colnprisin the key-stem f to select a articular type or and for creating a pin 'ra ity of electric circuits actuates or -projects it and its adjunotive parts to one of a pluralitv of operating or circuit-creating positions.

e first circuit is established when the crosstionf, arranged on the'terininalj", and the o eration of this circuit positions the latch so t at it can be operated. by the powcr bar when actuated. The additional continued projection of said key-sfern f" positions the thus reek the circuit, as the latch has there- .by been properly positioned. -lhc further" depression or pro ection of the key-stein actuates the power-bar to Opiaratotlie latch and'the type-bar. A further projection of said key-stern positions the levorj against that terinii'laland breaks the circuit tlltt(&--

through.

ation directed as a different an ever to force the terminal outward, and" My invention is to be distinguished from other devices in the art in that in operation the parts are'operated by a single circuit derived from a single source, which circuit is created three b one terminal first to effeet one operation, then interrupted through thateircuit and simultaneously. transmitted through a rliflerent terminal to effect a diflerent operation, and so on, which circuit through the medium of my invention is under positive control, first directed as adistinct circuit to a selecting-magnet to position 'a movable part. for actuation and then and in i succession and as a distinct and gositire open distinct circult to a power-bar operating magnet, which in operating its said ower-bar ectuates said movable part which as previously been positioned for such actuation. My said inventhe pending application in that it includes a lockmg device which operates automatically to lock the movable part after being positioned until the power-bar has actuated it, which said locki device insures the proper positioning oft e movable part unti the powerbar has effected its function.
