.To all wiz/m; t may concern.-

Be it known that l, WILLIS J. RoUssnL, a citizen of the United States, residing at New Urleans, in the parish of Urleans and State of Louisiana, have 'invented new and useful lmrovements in Electricaa.ll;yh()periit.erl.Type` riters, of which the following is a specificaf tion..

My invention relates to new and useful improvements in electrically operated typewriters; andts object is to rovide a device of this character which may e operated by a current transmitted through an ordinary telegraph-Wire.

A further object is to provide a machine havin an operatin -board composed of a suitab e number of eys each of which when depressed causes the machine to print a de# sired character. i

Another object is to employ operating means whereby the type-wheels of two Inachines located at opposite ends of the linewire may be operated in unison from each end of the line.

Another object is to employ novel mechanism for operating the carriage of each machine automatically for producing an impression loymeans of the type, forrotating the platen, and for returning the platen to its ini* tial osition upon the completion of a line.

ith the above and other objects in view the invention consists in the novel construction and combination of parts, hereinafter more fully described and claimed, and illus trated in 1'the accompanying drawings, show;

ing the preferred form ol' my invention, and

in whic l Figure 1 is a vertical section through one of the type-writers constructed in accordance with my invention. Fig. 2 is a horizontal section therethrough, showing the car" riage and type-wheel in plan. Fig. 3 is a section on line 3 3, Fig. 1, and showing in eleve tion the ratchet of the carriage and the pawl for operating the same. Fig. Ll: is n section on line 4 4, Fig. 1, showing the ratchet-sini ting cam. Fig. 5 is a detail view of one form of circuit-closing mechanism which may be employed in connection with the type-writer and its electrical connections being shown diagrammaticall Fig. G is a section through the dier of the operating device. Fig. 7 is an enlarged section through a por; a. o'

Referring to the figures by numerals of reference, i is a casing of any suitable form haying a spring or other suitable motor 2 thereon which is adapted to continuously rotate a gear 3, which is connected to the upper end of a tubular shaft 4. This shaft is arranged vertically within the casing and bears at its lower end within a tubular casting 5, having a slot 6 therein. 0ppositely-disposed slots 7 are formed within the shaft 4 at a point near the upper end thereof, and within these slots are slidably mounted arms4 l0, which are arranged within'and secured to a coneshaped slide 11, having a toothed or serrated face, as illustrated `iii-(Fig. 2. This cone is slidably mounted upon the shaft 4, and the arms thereof are integral with or connected to a spindle 12, which extends longitudinally through shaft 4 and is formed, preferably, of two telescoping members, having a spring 13 interposed therebetween and forming a cushion. upon the lower end of the spindle and has a laterallyextcnding lug 15 thereon, which is slidably mounted within a slot 16, formed within one end of a lever 17. This lever projects through the slot 6 before referred to, and one end thereof is connected to a rod 1&3, which extends upward through the tcp of the casing i, and has an armature 19 connected to its upper end and extended over a magnet 20. A spring 21 is mounted upon a rod 1.8 at a point between the casing and the armature and Serves tc hold said armature normally removed from contact with the magnets.

A block 22 is secured'to the rod 18 and has a springpressed pawl 23 therein which normally engages one of aseries of teeth 24, which project `from a flange 25, extending around a cylindrical typewheel 26. This wheel has a series of type 27 arranged in a line upon the periphery thereof, and it is loosely mounted upon a collar i'iclosing the shaft l uudprovided upon its super surface with a coneshaped projection .58, which incloses the sleeve 11, and is provided upon its in- A sleeve 14 is loosely mountedA ICO ner surface with teeth or serrations, as shownI in Fig. 2.. A ilange 29 is arranged upon the ulppersurface of the wheel and concentric t` erewith and is provided 1n its outer face 'with a groove 30, withiiiwhich is secured one guide and support the carriage of the mae'y chine. Arms 35 are slidably mounted on these rods and extend upward and are secured to parallel rods 36, whichy connect end plates 37 tothe carriage, having inwardlyextending flanges 38 atntheir upper edges. Rollers 39 are mountedll'pon these rods 36 and form bearings for a base-plate 40, which has downwardly-extending flanges 41 and 42 at its outer and inner edges, respectively. This plate extends under the flanges 38 before referred to, and coiled springs 43 are interposed between its flange 42 and the inner side strip 44 which connects. the end plates 37.

A horizontally-arranged connecting-strip 45 is located between and secured to the, inner arms 35 of the carriage at a point below the guide-rod 34, upon which said arm is mounted, and this plate serves to support a bar 46, having depending ratchet-teeth 47 at opposite edges thereof. This bar is slotted, as shown at. 4H, and is adapted to move latarally upon the rod 34a. The ratchetsI are held normally in position over retainingplungers 49 and 5() by means of a coiled spring 51, which is interposed between bar 46 and a strip 52, which connects the outer arms 35, as shown.

A. bracket 525 `is arranged upon the bottom casing l, and a lever .34 is iulcrumed therein and connected at one end to the rod 18. This lever has slots therein, and within two of these slots are mounted lugs 55, which extend laterally from the lower ends olE the plungers .naled within the casing l.

The other slot in level' 54 receives a lug 5E), which extends laterally from a rod60,slidablymounted in a guide 6l on the frame 5S and having a pawl 62 pivoted to the upper end thereof. A spring (SS serves'to hohl this pawl normallyv in engage? ment with a ratchet-wheel 64, which is secured to and revolves with a shalt 65, jour- A second springpressed pawl 66 also engages this ratehetwheel and is pivoted to ay bracket 67, whi'eb is inunovably secured within thc casing.` A Wliecl (3S is sccurcdto sha l't 65 and revolves therewith, and this whee has a series ol'vcamy 'ojections 6!) upon` the pcrigrihery thci'col'V which are adapted to be brought successively into Contact with the outer [lange 4l ci the carriage oi the machine. The inner end ol' frame 5S serves to support a rcwilublc rod 70, having an arm 7l, which cxtcnds laterall)v from thc upper end thereol", and a coiled spring 72 serves to hold said arm normally in the path of a pin 7b, which is secured to and extends downward from the lower surface of the tvpe-whcel 26. .rod 7() and is adapted when said rod is ro tatedeto bear upon the end ol' vthe bearing 46 ,and moveit.upunsthcfguide-ro(l l-lj, therebyr compressing springs 51 and removing the ratchet teeth 47 lrom position. above the plungers 4) and 50.

Standards 75 arc arranged above the bascplatc4() of the carriage, at opposite ends thereel, and are provided with transvcrselv-extending slots 76, within which are journaled necks 77, extending over the ends of a platen 7S of ordinaryform. A ratchet-wheel 7E) is connected to each ot' these necks and engaged by a spring-pressed plunger Hl), which is slidably mounted within ears S1, l'orined upon the standards 75.

A rod S4 is arranged within the casing and secured to A cam 7l is secured toV These plungers extend inwardly into the casing and are adapted to beA the top thereof, and upon this rod is niounted a ealn S5, having an arm 86, which is held,

by means oll a coiled spring 47, normally in the path ol' alug XS, which extends upward from the type-wheel 26. Springs 89 are mounted upon the guides S3, so as to hold the opcrating-strip S2 normally removed from the plungcrs St). Standards $3() are also located upon base-plate 4l) and serve to support a roller .l] which bears upon thc platen and is employed l'or holding a sheet-of paper in position thereon. A pullerV U2 isjournaled within a bracket 03 at one end ol' the casing, and a ilexiblc strip J4 extends thereover. (lne. end of this st rip is fastened to one end of the carriage-wheel, and the other end thcreol has a weight .)5 fastened thereto.

'l`he machine herein described is adapted to bc operated in airvsuitablc manner so that the circuit through the magnets 2l) may be closed l'or a desired period in order to print the propel' character. l preferably provide an operating device such as described and illustrated in a patent granted to me June 7; 1951i, and numbered 761,917. '[his mechanism comprises a hey-lever 96, which isvsupported upon a coiled spring 97 and is connected, by mcansoll a rod S,wit h one end oi' a cam 9S). 'l`hc curved edge ol' this cam projects into 'and is slidablv'mounted wit-hin a shoe lill), which is connected to one cud oi a sliding rod lili, mounted within carsltl, projecting laterali)y l'rom a supporting-braclwt TOO 103. The rear end of the rod 101 is connectedfhy means of a pitman 104, to a disk 105, which is revolubly mounted Vupon a short shalt 106, extending laterall from a hanger 107. This disk is formed oi hard rubber or ot er non-conducting material, anda stri 1.0 of copper or other conducting materia I is embedded in the periphery of said disk and is connected to the shaft 106 by an arm 109.` A hanger 110 is arranged adjacent to the disk 105, and to the lower end thereof is hinged an arm 11-1, paving a roller 112 journaled there- `in and he d normally in contact with the e riphery of the disk by a spring 113. A coi ed r spring 114 incloses the rod 101 and is secured to said rod and ada ted to bear upon one of the ears 102. The inewire 11.5 of an ordinary telegraph-circuit electrically connected with the hanger 107 and another wire 1.16 oi said circuitextends iirom the hanger 110 to the magnets 20, and a wire 117 serves to con-I duct the current from said ma ets to the round. One disk 105 is provi ed for each ey of v a keyboard, and the strips 108 upon the disks are oi different lengths. When it is desired to print a character, the proper key on the keyboard. is depressed andcain 99 is swun upon its fulcrum and causes rod 101 to sli e within ears 102, thereby compressing the sprin 114e. This longitudinal movement of the ro will continue until one-half a revolotion has been imparted to the disk 105. As soon as the key is released spring 114 will eX- pand and complete the revolution of the disk, and during this completion of a revolution strip 108, .embedded within the disk, will come into contact with the roller 112,and the Vcircuit will promptly be closed between wires 115 and 116. The magnets 20 will thus be energized and armature 19 attracted thereto.

rThis will cause rod 18 to slide downward, compressing spring 21, and lever 17 wil slide the sleeve 11 upward' into engagement with @the serrated tace of the cone 28` The sleeve and cone will be placed into engagement `before the pawl 23 `is pressed downward out oi' engagement with the teeth 24 on flange l25 of the type-wheel 26, and therefore the said' wheel will be held against movement and the motor 2 stopped until the downward move-` ment of armature 19 is stopped. As soon as the limit of this movement of the armature has been reached the pawl will become disel engaged from the teeth 24, the continued movement thereof being permitted by the spring cushion 13, which. is interposed between the ends oi. the spindle 12. When the teeth are released from the awl, the motor 2 will promptly rotate whee 26 and cause flexible strip 31 to be wound upon the grooved ilange 29, thereby :raising weight 33. Siniultaneously with the lowerin of rod 18 and the operation of the type-w ieel the plunger 49 is drawn downward and lunger 50 is 65 pres-ed upward. The teeth ci) the ititchets 1'7-y are so shaped that when plunger 50 comes upward into contact therewith it will force said ratchets longitudinally, and thereby raise the weight 95. lied is also moved up- Ward with plunger 50, and pawl 62 thereon. is caused to slip over a tooth of the ratchete wheel 64. The parts will be held in this position, with the type-wheel rotating, until the disk 105 has been returned toits normal poe sition by spring 114 and the circuit has been broken between the-wires 115 and 116. ,As soon as the circuit is broken spring 21 throws armature 19 away from magnets 20 and the pawl' 23 comes into engagement with p tooth 24 just prior to the removal of sleeve 11 from engagement with cene 38` and stops the action oi the motor until said sleeve and cone 'have become disengaged. The motor is stopped for a suliicient period by this p awl to permit the platen 78, with the paper t ereon, to be thrown against the type 27, which has been brought into proper position in relation to said platen. yThis movement of said platen is secured by the followin manner: When, rod 18 moves upwar propelled by spring 21, the outer end of lever 54 is swung downward and draws pawl 62 therewith. As this pawl is in engagement with. the ratchet-wheel 64, it will cause the lcarn-wheel 68 to rotate, and one ofthe projections 69 thereon will come into contact with the iront flange e1 oi the baseplate L10 and force it and the platen mounted thereon inward, thereby compressing the s rings 43. This entire o eration takes place uring the time in whic the type-wheel 26 is held by the pawl, and as soon as sleeve 11. dro )s out of enga ement with the cone 28 tie weight 38 wi return the wheel 26 to its normal osition, such movement being permitted by t e s rin pawl 23, which allows the teeth 24 to sip t ereunder when moving downward. It will be understood that when the armature 19 and .rod 18 move upward the plunger 50 will be withdrawn troni engagement with its ratchet'd?, and the plunger 49 will be returned to 'engagement with its ratchet 47 in time td prevent the ratchets and the carrie e connected therewith from returning to t eir normal osition. From the above explanation it wil be obvious that as the various characters are printed upon the type-writer the carriage will be moved longitudinally by the reciprocating 1plungers 49 and 50. lll/hen the end of a line las been reached and it is desired to partly rotate the platen, a key in the keyboard, which is em ployed for this purpose, is depressed and the operation above described is repeated. The type-Wheel, however, is permitted Vto rotate a suilicient distance to enable the lug 518 to come into n@nt/act with arm 86 oi' cam 85, andail'lnn will thus be drawn against the strip -82 and will impart lateral lne'ivernent thereto and causo it to slide upon the guides ilo loo

IOS

` contact with arms 71 and swing the same and i the referred form of my invention; but l do springs arranged thereon.Y When upon the thrown forward no imprint will be made upon 'modifications may be made therein without 4. eline? 83. This strip will come into contact with plungers and cause them to bear upon ratchet-Wheels 79 and partly rotate them. As soon as the lug 88 begins its return movement the cam will be returned to normal position by its spring 87, strip 82 will be returned to normal position by its springs 89, and the plungers 80 will be returned by the completion of a line it is desired to shift the carriage longitudinally, so as to begin a new line, 'a key in the keyboard, Which is rovlded. therefor, is depressed, and when t e Wheel 26 has been rotated a sufficient distance the pin 7 3, depending therefrom, Will come into cause rod 70 to rotate. This will bring the cam 7 4- against the side of the bar 46 and shift the same so as to remove the ratchet-teeth 47 from above the plungers 49 and 50 and the Weight 95, which is gradually raised as the carriage is forced along-by said plungers, will promptly" return the carriage to its normal position. When the cam 74 is released, spring 51 will return the ratchet-teeth to their normal positions.

It will be understood that a key will be provided upon the keyboard for forming spaces between the printed Words, and the mechanism employed for performing this operation is similar to that employed 4for printing a letter, with the exception that the type-Wheel 26 is rotated until a blank space is brought into position in front of the platen. it will thus be obvious that when the platen is the paper, but the carriage will be moved one space. A type-ribbon 118 may be mounted in any suitable manner so as to extend between the platen 78 and type-wheel 26.

In the foregoing description l have shown not imit myself thereto, as I am aware that departing from the spirit or sacrificing thev advantages thereof, and I therefore reserve the right to make such changes as fairly fall Within the scope of my invention.
