ELECTRICAL TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 747,485, dated December 22, 1903.

Application filed February 27, 1902. Serial No. 95,876. (No model.)

To all whom t may concern.-

Be it known that I, WTLLIAM EVANS RoB- ERTs, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Electrical Type-Writing Machines, of which the following is a specification.

My invention relates to type-writing machines; and the object of said invention is to provide a simple, rapid, and eflicient typewriting machine which requires lout little manual lahorto operate and wherein electricallycontrolled means are employed to bring about an actuation of various of the parts.

To these and other ends which will hereinafter appear my invention consists in the construction, arrangement, and combination of parts hereinafter described, and particularly pointed out iu the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure l is a vertical central front to rear sectional view of one form of type-writing machine embodying my invention. Fig. 2 is a detail perspective View of the type-carrieractuating device, together with the solenoid which actuates it and the connection to the escapement mechanism. Fig. 3 is a fragmentary vertical sectional view of a portion of the machine, the View illustrating the type-carrier just before it arrives at the printing position. Fig. e is a top View of the machine with theparts broken away. Fig. 5 is a detail face View of one of the linger-stall clamps. Fig. h' isa side View of the same. Fig. 7 is an enlarged detail fragmentary sectional View of the wire-holdingl bracelet. Fig. 8 is a rear View of the hand, showing the application of the finger-stalls and cable-bracelet thereto. Fig. 9 is a fragmentary front elevation oi' the type-writer support or table, showing the clamps applied thereto. Fig. lO is a fragmentary Vertical sectional View taken through the spacing contact-plate. Fig. ll is a front to rear vertical sectional View of the machine, illustrating the spacing contact-plate depressed and a type-bar just before it arrives at the printing position. Fig. l2 is an enlarged detail fragmentary sectional view showing a typeloar and its actuating and selecting mechanism. Figs. 13, 14, and l5 are fragmentary detail front views, with portions broken away, of the spacing and selecting contact-plates, the view illustrating the various steps during the actuation of a typecarrier through the depression of the spacing-plate. Fig. l6is a diagrammatic plan View of the circuits. Fig. 17 is a fragmentary plan View of a mcdified form of machine embodying my invention. Fig. 18 is a fragmentary Vertical sectional View of the same,taken through the front portion of the machine. Fig. 19 is afragmentary detail side view, with parts broken away, of a portion ofthe means for shifting the platen. Fig. 20 is an enlarged detail transverse sectional view of the same, taken on the line :om of Fig. 19.

In the drawings parts have been omitted and broken away to `oetterillustrate other features of the construction.

I have illustrated my invention in its application to a machine which is essentially the same in many of its features as the No. 6 Remington type-writing machine, though it should be understood that the invention is applicable to various other characters of writing-machines, and to this end various changes in the construction and operation of the machine may be made without departing from the spirit of my invention.

Referring iirst to Figs. l to I6, inclusive, of the drawings, l indicates the frame of the machine, which is provided with a top plate 2, that supports upwardly-projecting studs 3 4L, which carry traverse-rods 5 and li, respectively, on which a truck 7 of the carriage moves from end to end of the machine. The truck has operatively connected thereto a platen-frame 8, which travels with the truck and is provided with a revoluble platen 9. 'llie platenframe has a traverse `grooveil roller l0 pivoted thereto and which is adapt- 9 ed to bear upon a shift. rod or rail ll and to move the platen-frame in the usual manner ina direction transverse to the length of the platen for upper and lower case printing. The sl1iftrail is supported upon arms l2,

IOC.

which are pivoted to a fixed portion of the machine at 13 and are provided with depending arms 14, that are each connected at 15 to a depending link 16, which is pivoted at its lower end 17 to a lever 1S. The shift-rail is restored to the normal position by a spring 12X, connected at one end to one of the arms 12 and at its opposite end to a fixed portion of the machine. The levers 13 are united at their forward ends by a cross-bar 18X, and thus form with the cross-bar a yoke, and the rear ends of these levers are pivoted at 19 to the frame of the machine, and the yoke as a whole is restored to the normal position bysprings 2O and 12X.

The top plate may have the usual hangers 21, secured thereto by screws 22, and pivoted in each hanger at 23 is a type bar or carrier 24, which is provided with a plurality of types 25 thereon. The heel of each type-bar is connected at 26 to an actuating-link 27, that has a hook or abutment 23 at its lower end, and each actuating-link 27 has one end 29 of a contractile spring 30 secured thereto.A The opposite end 3l of each spring` may be secured to a depending stern of the screw 22, which secures the associated type-bar hanger in place, and the tension of each spring 30 is exerted to draw the lower end of the actuating-link away from its associated type-bar. The actuating-links 27 maybe arranged in a circle, with theirlowerhook-like ends extending below the plane of the lower face of the actuating device or disk 32, and the relation of the parts is such that the hook-like ends 28 of the links are normally out of the path of movement ofthe disk. When, however, any of the actuating-links are moved inwardly around the connection 26 as a pivotal center,the lower hook-like end thereof will be brought beneath the lower face of the actuating-disk, as represented at the right-hand side of Fig. 1 of the drawings. Should the disk be depressed at this time, it will be understood that the type-bar of the associated link will be moved to the printing-point, the downward movement of the disk being limited by a dxed ring 32. This ring has a cam-face 32h, which is effective to move the hooked ends of the links outwardly during the downward movement of the disk, so that they are automatically released just before the type bar reaches the printing position, as represented in Fig. 12, and the momentum of the typebar will bring the type thereon to the printing-point, and the rebound of the bar and its spring 30 will immediately restore the link and type-bar to the normal position. The actuating-disk 32 is preferally connected by threaded connections 33 to an insulatingpiece 34, which is in turn connected by a screw 35 to the core or armature 36 of the solenoid or electromagnet 37. This solenoid is supported upon and insulated from a plate 38, which is secured to the frame of the machine by brackets 39. The core or armature 36 is likewise provided with a downwardlybracket 45, that is secured at 46 to the frame y of the machine. Pivoted to this lever at 47 intermediate of its ends is a link 43, which has its upper end connected at 49 to a crank-arm 50, which projects from a rockshaft 51 of the dog-carrier 52. The solenoid core or armature, with the parts connected thereto, and the dog carrier are restored to the normal positionby a spring 53, which is connected at one end 54 to the frame of the machine and at its opposite end to the rock-shaft 51. If desired, a separate spring may be employed to aid in the restoration of the parts to the normal position. The dog rocker 52 may be provided with the usual feed-dogs 55, that coperate with an escapement-wheelG, that is operatively connected with a shaft that rotates in a bearing 57, secured to the top plate of the machine. The forward end of this shaft is provided with a feed-pinion 53, which meshes with a feed-rack 59, carried by the carriagetruck 7. The solenoid core or armature and the act ual-ing disk ordcvice32 maybe guided in their Vertical movement by antifrictionrollers 60, carriedin brackets 61, that extend from said device, and the antifriction-rollers are adapted to bear on the side walls of the guide 62, which is secured at 63 to a supporting and guide plate 64, which in turn is secured to the frame of the machine by screws 65. The plate 64 has guiding-slots 64 therein, through which the actuating-links 27 eX- tend, the side walls of the slots limiting the lateral movement of the links.

Surrounding the actuating-links 27 and circularly arranged on the supporting-plate 64 is a series of solenoids or electromagnets 66, one of such solenoids being employed for each actuating-link. Each solenoid is provided with a core or armature 67, that has an insulating-head 63, which is adapted to bear upon the associated actuating-link 27, and when a solenoid 66 is energized the core 67 thereof will force its link inwardly against the tension of its spring 30, so that the hooklike end of the link will be forced beneath the actuating device 32, and upon the downward movement of said device the connected type-bar will be moved to the printing-poin t. During these movements of the parts the hooked end of the selected link will be carried off the edge of the disk Orring 32, so that the hook is released just before the typebar reaches the printing position, and when the circuit which energized the solenoid 66 of said link is broken the tension of the spring 30 of the associated link will become effective to restore the core 67 of said solenoid to the nor` mal position.

The so-called selecting contact-plates 69 are pivoted upon a rod 70 and are suitably IOO IIO

rig

'rer/,ess

insulated from the frame of the machine, and each of these plates is normally maintained in the elevated position by a spring 71, which is secured at one end 72 to one of 'the plates 69 and at its opposite end 73 to the frame of the machine. Secured to and depending from the plates 69 are bracket-arms 7e, which are united at their lower ends'by a cross-bar 75, which extends `beneath a centrally-disposed vibratory shifting contact-plate 76, that is pivoted upon the rod 70. This contact-plate 76 is secured by angle-irons at 77 to the iorwardly-projecting arms of angle-irons 78, which are secured to the cross-bar 18X, that unites levers 18. It will be understood that a depression of the contact-plate 76 will cause the arms 12 to be vibrated against the tension of the spring 12X, thus moving the platen in a direction transverse to its length to bring about a shift of the platen lor upperand lower case writing. Upon reference to 14 and 15 it will be observed that lost motion may be provided in the link 16 by the arrangement therein shown. Thus, for instance, the lower end of the rod 16"L is provided with a crosshead 79, which works within guide-slots in a yoke 80, that is pivoted at 17 to the levers 18, and an expansion-spring 81 is interposed between lhe yoke and the cross-head. rilhe tension of this springis suflicient to canse a transmission ot movement through the rod 161L to `the arms 12 when the shift-plate is depressed, and thus effect a shifting movement of the platen. After the full-shift movement has taken place and the transverse movement of the platen-frame is arrested a further downward movement of the shift-plate will cause a compression ofthe spring 81, so as to permit the angle-iron 78 to contact with the cross-bar 75, thus causing the contact-plates 69,to which said cross-bar is secured, to be electrically connected to the plate 76 and to be forced down or to follow the shift-plate 76 during` a still further depression of said plate. One of the contact-plates 69 is provided with a Contact 82, that is adapted to bear upon the contact 83, which is supported by a bracket 84, that is insulated at 85 from the machine. This bracket 8i is provided with a binding-post 86, to which a wire 87 is connected, and this wire extends to a battery 88, and a wire 89 leads from this battery to the solenoid 37. The return-wire 99 leads from the solenoid to a binding-post 91, which is carried by a plate 92, to which the contact 82 is secured, and

, this plate 92 is insulated at 93 from the conconstitutes a portion of a separate and distinct circuit, which is formed by the battery 95, a wire 96, a solenoid 66, a wire 97, a contact 98 on the finger of the operator, one of the contact-plates 69, and the return-wire 94. ln the diagrammatic View shown in Fig. 16 these various circuits are illustrated, each circuit being shown with a separate connection 99 on a contact-plate 69. It should be u ndersiood, however, that these various wires 94C may be hunched in two groups and the terminals for each group connected to a single binding-post on one ot' the contact-plates 69. 'lhus it will be seen that one half of the circuits may be made through one of the contact-plates 69 andthe ot her half made th rough the other contact-plate 68,01', in other words, that the wires of one haltet' the selectingsolenoids 66 are connected to one of the plates 69 and the other half of the solenoids 66 are connected to the other contact-plate 69. lt is merely necessary for the operator to place one of the contacts 98 upon a contact-plate G9 when a current will be established to energize the particular selecting-solenoid 66 for which said contact 98 is provided. The energizing of the solenoid 66 will force the core or armature 67 thereof inwardly, thus moving the hook-like end 28 of the associated actuating-lin k 27 beneath the actuating device or disk 82. 1t will be seen that little labor is required, and no manual movement of the parts is necessary to bring about this selection of the type-carrier to be actuated. A slight depression upon the selecting contact.- plate 69 at this time will cause the contact 82 thereon to bear upon the associated contact 83. This will result in energizing the solenoid 37, which will cause the core or armature 86 to be drawn down, together with the actuating device 32 secured thereto, and the selected type-bar will be moved to the printing` position. This same movement of the solenoid-core 66 is effective to actuate the escape/ment mechanism and to permit the carriage to be moved by the usual spring-drum, (not. shown,) when the core moves back to the normal position.

lt is of course immaterial at what point on a contact-plate 69, or either or them, (because they are electrically connected by the crossbar 75 and, in effect, constitute one plate,) a contact 98 bears, so that the operator has no need of fixing attention upon a keyboard,as is ordinarily the case. 'lhere may be any suitable n umberof contacts 98 secured to each iinger-stall or carrier 100, which is adapted to iit the fingers ot' the operator, and each contact is connected in the construction thus lar described with a single selecting-solenoid 66. 1n the present construction the machine is shown provided with seventy-six characters, and these seventy-sir; characters may be selected and printed by 7the contacts carried by the fingers ot the operator and the coperation ofthe selecting contact-plates 69 and the shift-plate 76.

Should the operator press upon the shittplate 76 with one ot' the contacts 0S so as to move said plate from the position shown in Fig. 13 to that represented in 1e, lthe platen will iirst be shifted transversely bythe mechanical connection, and when the angleirons 7S reach contact with the bar 75, as shown in 14E, an electrical connection between the plate 76 and the plates 69 will be established and a current will pass through a selecting-solenoid to move, the particular actuating-link which corresponds to the selecting-contact 9S on the plate 76 into the path of the actuating device 32. t further depression of the plate 76, which is allowed by the spring connection in the link 10, will cause the plates 69 to be forced down with the plate 76, thereby bringing the contact 82 on one of the plates 69 to bear upon its associated contact 83, when the circuit will be closed which energizes the actuating-solenoid 37. The core 36 will then be drawn down and the particular' type-bar selected by the contact 98 which bears upon the plate 76 will be moved to the printing position. lt will therefore be seen that the shift-plate 76 is not alone effective to bring about a shift of the platen, but that a movement of this plate will select and operate the particular type-carrier which corresponds to the contact 98 that is brought to bear upon the plate, so that a single depression of the shift-plate 76 accomplishes a threefold result-that of shifting the platen, selecting the type-carrier to be operated, and actuating the type-carrier. YL/'hen the operator desires to feed the carriage without actuating a selecting device and without therefore operatinga type-bar, it is merely necessary to depress the vibratory selecting-plate without bringing a selecting-contact 9S to bear thereon. This will yresult in the contact 82 bearing upon the contact S3, and a current will be established through the solenoid 237 and the escapement mechanism will be actuated. l/l/'hile the actuating device 32 is moved, at this time no printing` will take place, for the reason that a selecting-solenoid has not been energized and all of the hooked ends ol the actuating-links 27 will therefore be ont ot' the path oi the disk or ring 32.

Frein the foregoing description it will be understood that the solencidmagnets 60, their cores 67, and the links 27 constitute selecting means or devices. These are lirst operated to select the type-bar to be actuated, and the subsequent operation ot the actuating device or disl; 32 will effect an operation ot the selected type-bar.

Upon reference to Fig. Sit will be observed that the various wires 97, which extend from the contacts carried by each finger-stall 100, are united to term a cable 97X, which passes through a guide 101, and that these various cables from the fingers of the operator are united into a single cable 97, which pa ses through a gnidein a bracelet or support 102. This guide maybe formed by a strap 103,

vean-ce which is secured at one end 104 to the body of the bracelet and may be provided with a clasp member 105 at its opposite end that cooperates with a clasp member 100, carried by the bracelet. The cable 07 is placed in position and the clasp-carrying end of the strap 103 is secured in place and the cable may extend a single cable until it arrives at the machine, where connection is made between the respective solenoids and the wires 97, which make up the cable.

ln order that the finger-stalls may be maintained in their proper order, so that each iinger-stall maybe attached to the particular finger for which it is intended, it is deemed desirable to provide finger-stall clamps 107 for supporting` the linger-stalls when they are not in use. Upon reference to Fig. 9 it will be observed that these clamps may be secured to the table or support for the machine and that the arrangement thereof is such that the lingers with the iinger-stalls thereon may be inserted in the clamps, as represented in full lines in G. rlhe clamps 107 are each constructed with a base portion 10S, through which the screw 109 may be projected to secn re the clamp in place to a suitable support. Each clamp is provided with a rigid arm 110, that has a groove 111 therein, and extending from the base 108 are resilient clamping-arms 112, which are smooth on their inner face and are spaced apart throughout their lengths and adapted with the rigid arm 110 to surround a iinger-stall,as well as to allow an endwise insertion of a 'linger-stall in a clamp, as illustrated in Fig. 6. ln order to remove the vnger-stalls, it is merely necessary to insert the lingers with the stalls thereon into their respective places in the clamps, when the collar or lug 113 on each finger-stall will seat itself within the groove 111. The lingers may then be withdrawn and the stalls maintained in the clamps. When the operator desires to place the stalls upon the lingers, it is merely necessary to insert the lingers therein in the same order in which they were withdrawn and to slightly raise the lingers with the stalls thereon, as indicated in dotted lines in Fig. 6, thus removing the lugs 1123 from their respective recesses 111 and the `ngers may be drawn ont of the clamps with the stalls in place thereon.

1n the modification shown in Figs. 17 to 20 of the drawings the same reference characters are employed to indicate the parts which are the same those shown in the other ligures. ln this inodilication each selectingcontact 98 on a linger of the operator is connected to two wires 97, which extend to separate solenoids or electromagni-its 66u. There are likewise two selecting contact-plates 09 ein )loyed in this construction, and each of said plates is provided with a contact S2, that coperat-es with a contact 83, and each of said contact-plates is likewise provided with a binding-post 91, to which the wires 90 are connected, and these wires are joined IOS IIO

"realise at 90b, and the single branch thereof extends to the solenoid 87. A single fixed bracket 84E, which carries the two contacts 83a, is provided with a binding-post 86, to which is secured a wire 87", that passes to a battery 88, and the wire 89 extends from this battery to the solenoid 37. The terminals`99a of the wires 94 are connected to the contactplates and extend to a battery 95, and the wires 96n extend from this battery to the solenoids 66a. There are likewise provided two shifting contactplates 76, both of which are constructed in a similar manner, each being electrically connected at 77 to a metallic plate 78a, which is adapted to cooperate with the lateral extension of a bracket-iron 74?, which is secured to one of the contact-plates 69a. It willbe understood that the operation of this modified construction is the same as the construction formerly described, except that each selecting-contact 98a is adapted to select a plurality of typecarriers by reason of its connection with the plurality of the selecting-solenoids 66, the particular type-bar selected depending upon which of the contact-plates 69m the selectingcontact is brought to bear upon. Thus, for instance, if a selecting-contact, as indicated in Fig. 17, is brought to bear upon the righthand vselecting-plate then the solenoid 661 (shown to the right in Fig. 17) will be energized. On the contrary, if the same selecting-contact 9S is brought to bear upon the left-hand selecting-plate 69 then the lefthand solenoid 66L (shown in Fig. 17) will be energized and the associated actuating-link 27 will have its hooked end forced beneath the actuating device 32. After the selection has been thus made a depression of the contact-plate tif)a will cause the contact 82a thereon to be brought to bear upon its coperatingcontactS,thusclosingthecircuittln'ougb the actuating-solenoid 37 and causing the actuating device 32 to operate the type-bar through theselected link. The upper end of each connectinglink 16X passes through an aperture 114C in the depending arm 141, which is connected to each of the arms 12, that carry the shift-rod 1l. The rod ltiXis provided at its upper end with a pin 115, which extends to opposite sides thereof and constitutes a stop, which causes the arms 12 14 to be moved therewith during the downward movement ot' a link 16X, but permits the arms 14 to move downwardly independently of said links. This is in order to permit an independent movement of the shift-plates 7oa at opposite sides of the machine. Thus, for instance, when the shittplate upon one side of the machine is depressed it will cause the shift- -rail 11 to be moved through the intermediate It should be understood that any desired number ot' contact-plates 69 may be employed and that the greater the number of shiftplates the greater will be the reduction of selecting-contacts carried upon the fingers of the operator. If three selecting-contacts be employed, then each selecting-contact upon a finger of the operator will be connected with three selecting-solenoids and each selectingcontact will be available to energize any one of the three selecting-solenoids in accordance with the contact-plate u pon which itis brought to bear.

While I have shown and described with considerable detail two forms or embodiments of my invention, it should be understood that various changes in construction and operation may be made without departing from the spirit of my invention.
