To all whom t 71mg/ concern:

Be it known that I, EDWARD E. KLEIN- scinrin'r, a citizen otl the United States, residing in Chicago, in the county of Cool: and State ot' Illinois, have invented certain new and uset'ul Improvements in Telegraph Printers, of which the following is a speciiication.

My invention more particularly relates to a printer of the typewriter type for use in a telegraph system.

The object of my invention is the provision of novel 'features in a telegraph printer of the character indicated by which the speed ot' the printing is increased and the general eihciency of the machine improved.

My invention will best be understood by reference to the accompanying drawings in which I have illustrated one embodiment of my invention, and in which Fig. 1 is a sectional view taken for the most part on the lines 1 1 ot Fig. Q looking in the direction ot the arrows. the upper portion of Fig. 1 being taken, in general, on the upper part of the line 1-1, while the lower portion thereof is taken on the lower part ot' line 1 1: Fig. 2 is a plan view taken on the line 2-2 of Fig. 1: Fig. 3 is a front elevation ot the printer with parts broken away; Fig. 4 is an enlarged rear elevation of a part of the printer: Fig. 5 is an enlarged front elevation of the selecting device: Fig. 6 is a side elevation ot the operating bar and associated parts for controlling' the operation oit the carriage return; 7 is detail side view ot the universal bar actuated by the type bars and the connection to the ribbon shield and spacing contact: Figs. 8 and 9 are detail views illustrating parts of the paper carriage: Fig. 10 is a detail view illustrating the shift-locking mechanism: Fig. 11 illustrates a construction by which the movement et the universal operating bar fails to move r. cooperating pull bar.

Renewed Gctober 26, .1925.

Like reference characters indicate like parts throughout the (.lrawings.

I have shown at` A, Fig. 2, the trame ot' the machine. I will lirst described the selecting mechanism by which the various type bars ot the printer are selected and actuated. Referring now to Fig. 1, 1 .is one of the type bars, ot which it will be understood there is a plurality, and which in the form here illustrated are similar in construction to those used in a typewriter of well-known form. All of the type bars arev pivoted at a common t'ulcrum 2, and in normal or inoperative posit-ions, their outer extremities rest on a pad The pivotal points of the type bars are arranged in the segment ot a circle in the usual manner, in order to bring the type` on the free ends of all off the type bars to the same point on the ribbon when the type bars are operated, a common curved bar, in the 'term here illust-rated, providing the pivot on which the type bars are hung. A series ot' vertically disposed arms 4 are pivoted at a common tulcrum 5: the lupper ends ot the arms being provided with pins 4a engaging' in slots 5 at the inner ends of the type bars. To each ot the arms 4 is pivoted, at 4b, a pull bar 6 to which is connected a spring T tending' to depress the pull bars and pull the same to the lett, as viewed in Fig. 1. In order that the same longitudinal movement ot the various pull bars 6, which it is convenient and desirable to produce, may produce the same movement of the various type bars, the pivotal connections ot the arms 5 at their lower ends are arranged in the form of a segment reversely arranged with respect to the segment on which the type bars are pivoted, as bestl shown in Fig. 14. The pull bars 6 are all arranged in the same horizontal plane, and are preferably pivoted to the arms 4 at points considerably below the middle ot the latter. By the described arrangement, the same amount of longitudinal movement of each ot the pull bars produces the same movement o'f the upper ends ot the arms 4, and of the type bars to which they are connected. While I have described a segment to which the lower ends ot' the arms 4 are pivoted, it will, of course, be understood that the same result would be produced by straight sections arranged mere or less in the form of a segment. Each of the pull bars is provided Cil With a downwardly prejecting` lug (in, which normallyv rests on a` roller 8 normally entendingr beneath and Which is common to all ot: said lugs. 'lle roller 8 is moilnted in a roel*- ing` iframe 9 and is actuated by a magnet or solenoid 10. Mounted on the trame 9 is a universal bar or bail ll which, when the trame 9 is moved to the right, indicated in Fig. l. engages the lugs 6 on any o't the pull bars 6 which may be depressed.

Selecting; bars 1Q, the same in niunber as the selecting` magnets7 and here shown as 5 in number, are mounted in standards lil and let transversely of and underneath the outer ends ot the pull bars 6., as best shown in Fig'. 3. The live selecting bars have sl. cut in their upper edges to correspond with the code used to operate the Iypewriter, that is to say. by moving different combinations of the select ingr bars longitudinally, slots in the upper edges ot all of the selecting; bars are brought into alignment in various positions and directly underneath the. various pull bars, so that one of the latter is permitted to drop therein. Underneath the selecting bars is mounted in the standards lf? and t4 a` longitudinally movable carrier l5 in which carriage live paivls 1G normally7 depressed by springs 16" are pivoted. liatches l?, one `tor each paivl, are also pivoted on carrier l5. the latter being' provided with shoulders, as shown in 3, which engage the paul in both its depressed and elevated positions5 a spring i6 tendine' to force the upper end ot the latch beneath the paivl and hold the latter in its elevated position. Each paivl is provided with a bent finger 16h, which. When the pavvl is raised, engages a notch l2 'formed in the lower side of the corresponding selector bar 19.

Each oit the selecting magnets 18 is provided with an armature if) pivoted at 19@ (see Fia'. 2). Each armature is normally held away 'from the magnet by a spring' ll) (see l). il. projecting` arm '19 on the armature cnn/'agree underneath a cor` reponding; paWl7 shown in Fig. il, in order to raise the latter when the correspondingly manrd net is energized.

A. core 2() is actuated by the 'solenoid 2l which is lrnoivu as the sixth impulse map;- net. 1When solenoid 2l is energized and its core raised, the latter engages one arm ot a bell crank 22 (see 5) pivoted 22, the other arm of which engages carrier l5 in order to move the latter to the right, as vievved in Fig. 5. rlhe 'forward movement of carrier 15 also actuates those selector bars with Which the corresponding paivls are in engagement. Then carrier 15 is substantially at the limit ot its movement, the lower ends ot the: latches l? engage the upwardly extending; kposts 23, as best shown in llifr. and the latches are thereby disengaged troni the paWls. A spring 24 (see Figs. and

neen-lea iwhich preferably slit longitudinally for a portion oli' its length to provide in ei'lect, a separate spri k "or each select. bei'. is provided With a l: -shaped projeciion /-l Wh ich engages in slots lg and l2 in the selector l bars `When the latter are in their normal positions or moved to their Yfoi'irard positions, respectively.

il plate 2T is held against the l'orivard end of the selector bars l2 by a light spring E29. This plate is eugaeed by a second plate 30, preferably terme-d at its upper end with a. bent part 52W, which engages tie plate il? and is held against the same by a coinpara. tively still spinne; 'llil l te 3() is proby the selector bars l2. as viewed in .'3,

a latch pivoted at and having; a detent which normally rests against the plate 2"? is pulled in behind the plate by a spring` and retains the plate in its forwardly moved position. rlhe opposite end ot' the latch 33 is provided with a piece ot insulatin@1 material 3G Which bears against tivo tlat contact springs 37 and 38 carrying' contacts Si" and 38, resiieetiveljf, which normally engage tivo stationary contacts flO and 3. 7 carried by spring` lingers e0 and 39. respectively, thereby opening;` the tivo sets ot contacts, While the latch is in the normal position shown in lligr. 2. the springs 3i' and 8S closing` the tivo sets ot contacts when the latch is in its retracted position. (llosing1 the First set ot contacts Gld and 539 completes a circuit throuejh the operating solenoid or magnet l0. the encrn'iaation ot which attracts the core l0" to which is connected the link or linlis all which are.. in turm pivoted to an arm 41'? which rotates shalt il-3 and moves the trarne 9 with the bail il, iu the manner previouslyrr described. lo move tor- Wardly any pull bar 6. which may have been depressed. by dropping? into the slot termed in the upper edaes ot the selector bars. rlFhe closing' ot the serond set ot contacte 37a and fl-O completes :i pre-eneroizing circuit through the magnet G6. the ci. the magnet at this time, because ot 'the fact that a resistance G6 is included in the circuit. being; insuilicient to operate its armature. but sutheient to reduce the time 'for its operative energization. in the manner heres inatter described. the type bar l nears the end ol its upward stroke. an arm il attached to rocker trame 9. and carrying a bar lo sliding on a l.duide sere f lo engager by means of an upwardly projecting lug;n 45

ization oi A lll) the latch (see Fig. 6). The movement of the latch 33 releases plateQT, and it, together with plate 30 acted upon by springs 29 and 3l, restores the selector bars 1Q and the storage carriage l to their normal positions, shown in Fig. 5; at the same time, contact springs 3T and 38 have forced contacts 37a and 38 away from their opposing contact points 40 and 39, thereby causing the magnet l0 to be deenergized, and the various parts connected to its armature to be returned under the tension of a spring 9a. It will be apparent, therefore, that the magnet l0 is energized during the time that the plate 27 is locked in the position to which it has been moved, and the magnet remains energized until the mechanism actuated the-reby which operates the printing mechanism has been operated. and the plates 27 and 30 thereby released and permitted to restore the selector bars to their normal positions. lVhile the parts actuated by the magnet are operating, the magnet 2l, which operates the carriage 15, has been deenergized and the carriage restored to its normal position by a spring 15a (seeI Fig. By permitting the storage carriage to return while the parts actuated by the operating magnet 10 are operating, the overlap and speed of the device are correspondingly increased.

Means for regulating the force of the blow struck by the type bar l, and thereby the impression on the paper are provided and are shown in Fig. 6. The arm 42, which is actuated by the link 4l, instead of being rigidly fastened to the rocker shaft 43 which carries the frame 9, moves freely thereon, while it imparts its motion to said shaft through the medium of a spring 49 and an adjustable arm 50 secured to the shaft 43. A dash pot +118, the piston or plunger 4:7 of which is connected to the outer end of the arm 4t2, is provided to prevent shock to the parts moved by the solenoid.

The described apparatus for bringing about the operation of the selector bars and a printing` operation constitutes one of the important features of my invention, since it gives a greater overlap and increases the speed of the printing operation. It will be apparent that as soon as the carriage 15 and the selector bars 12 have been returned to their normal positions` a new combination may be set up by the selector magnets while the printing operation brought about by the previous combination is being carried out.

I will now describe the next operation in order 'following the printing of a letter by the type bar l, which is letter spacing. Referring to Fig. 7, a rocker shaft 5l. pivoted in bearings 52 and 53 which are a part of the frame work, carries two upwardly eX- tending arms 54 and 55 which carry a bail or universal bar 56, pivoted at their upper ends, as at 57 and 5S. An extension 56 of the bail projects into a recess in the block 59 (see Fig. l). This extension 56 serves to restore the type bars l on their pivots lli'hen a type bar l is operated and ap m'oaches the end of its upward stroke, a shoulder l near the pivot 2. engages the projection 56 on the universal bar and pushes it back against the tension of a spring 6() which is attached at its upper end to a :f'ationary part. and is fastened at its lower end to a piu 61. in the rocker shaft 5l. From the upright extends a flange 62 (see Fig. T) carrying an insulated screw 655 which bears against a contact spring (iet and in its normal position holds it away from and out of contact with spring 65, but when bail 56 is pushed back, as described, the two springs (tt and make contact and close a circuit through the spacer magnet G6, as indicated in Fig. 13. No resistance is included in this circuit at this time, and the magnet 66 is operatively energized.

Referring to Fig. 2, the magnet 66 has an armature 67 carrying a pawl 68, which engages teeth on a ratchet wheel 69. lVhen the magnet 66 is energized and draws the pawl 68 from engagement with the teeth on ratchet wheel 69, the ratchet wheel is prevented from following by a retaining pawl 70, which is arranged. however, to release the ratchet to permit the return of the carriage, in a manner which will be hereinafter more fully described. The operation of the magnet 66 causes no movement of the ratchet wheel 69, but after the type bar 1 has printed its character on the paper and has returned toward its normal position far enough to open contacts 64, 65 again, thus fle-energizing magnet 66. the pawl 68 engages a tooth in advance of the one which it last held and rotates the ratchet wheel 69 one tooth, a spring 71 furnishing the motive power, which has been stored up in it by the operation of magnet 66.

Referring now to Fig. 4t, the ratchet wheel 69 is fastened to a shaft 72 which carries at its upper end a pinion 75l engaging a rack 74. and forming a sliding engagement there with when moved up and down in the manner hereinafter described. rllhe rack 74. is attached to the paper carriage and a movement of one tooth on the ratchet wheel 60 moves the paper carriage forward one letter space. Each letter bar 1. Fig. l, when operated causes the paper carriage to be moved forward one space. as described. Spaces between words are made in like manner. the only difference being that the particular bar l used for word spacing carries no type at its upper end, and, therefore, does not print on the paper.

The shaft 72 is enclosed by a easing or housing 721. A coiled tension spring 76 surrounds the shaft 72 and is disposed between the shaft and the easing. @ne end of the spring is fastened to the casing while the opposite end thereof, and here il lustrated as the lower end. secured a collar 9, which a 1' istablv zecured to the shalt as by a s tsereuv 724e. lli' the described means, the tension ot the siriane@r 76 may readily.v be adjusted. Associated with the spacii is the carriage return magnet la. taneous operation oi? thesey tiro magnets necessary to release the cari-laire and allevl it to return under the tension of a n 76 (see et). 'lhe selection oll the carriage return is made by the selecting` rangement in the same manner as a letter selected, and such selection has already been described. The pull bar 6b (see f) which controls the carriage return has only a Vertical motion and its 'function solely to close a Contact. The horizontal moti which is imparted to .letter hais o bj magnet 66 The si uint the b2` 11 striking the projection 6"L (see Fig. 1) is eliminated in the case oli the bar 6b by cutting a slot 11n in the bail l1 opposite the bar. There are three bars which are thus operated, namely, the carriage return, line 'feed and the ligure shift. Attached to the. bar 6b is a piece of insulating material 7S bearing against a spring` 1.79 and uf'hich in its normal position holds a Contact on sai-d spring out or' engagement with a contact on a spring;v 80, the contacts themselves not being; shown in Fig'. 3, but being indicated in Fig. 13. lllhen closed the contact springs 79, close a circuit including the carriage return magnet and the space magnet 66 which is connected in series therewith, (see 13). Referring' to llifv a shoe 81 on the paWl 68 strikes a libro hloek 62 as the armature 67 is pulled back and throws the end olf the. pawl clear oit the teeth on the ratchet Wheel 69, at the saine time that the magnet 75 attraets its armature and diseng'an'es the retainingiv paWl i0 which is secured on sai-d armature. the armature being pivoted at S3". Attached to the armature S3 is an arm 84.1. carrying a block 85 or insulating material which` when the` armature is attracted.y moves the sprint? 66 into contact with screw 8T.

Referring;I to circuit diagram. Fig. 13. it will be seen that the magnets 66 and 75 are now locked up through a circuit including; contacts 86. 8? and S8. 89 independently oit contacts 79. 8d which close for a moment only during; the operation. ot magnet 10. This locking; circuit is provided so that ainple time Will. be niif'en for the carrfarre to return before releasing; the magnets 66, '75, which is accomplished by a lue' on the earriage striking` a contact 88 and breaking its contact at 89, (shown only di.ao;rainmatically in Fig'. 13). rlhis takes place only as the carriage reaches the end ot its return, the

contacts @3, SU beine; held open in that posi-- tion.y but iinmed'itely the carriage makes one space, contacts 8S, S9 are airain closed. ln addition to the control of the carriage vn by closing contar.' l0. 80, which is accomplished by sending` the nroper selective impulses over the line. a local carriage return circuit is provided and is completed by a push button Si() (see liefi i3) in the side or the printer trame, which may be pressed into contact with the point 91. thus (,:losinii` the same circuit as do contacts itt 80.

"l .nig to Fi a n'ianually operated piroted al 92a carries a Wire 93 constilutinn' a lint: connectinn said arni to the armature ot the magnet 75. said arm being' held in the position shown by a spring 9er which is attached to 'the lever 92 at one end and presses against the block 82 at the other end. l/llhen lever 92 is moved against the tension oit spring` Sieh it carries With it the armature 67 and paWl 68 oli' magnet 66; also by means oi? the wire linlr 92E, it mores armature 63 oi' magnet and disengages retaininn; pair] 70. lhe ratchet Wheel 69 is new tree and the carriapge is permitted to return under the tension et spring '76 as already described.

Line feed.

'.lhe operations involred in selecting the line 'feed is similar to the selection of the return and need not be described. pair of Contact points 95, 96 tdiapnarnn maticallv shown in Fig. 13, but not other- Wise illustrated) are brought together and circuit is closed through line-feed magnet 97, when the carriage is returned to its normal position. Magnet 97 is provided with an armature 98 Which carries an arm 99 passe ine` through a guide 100.. and is held in the elevated position shown in lling. 1, by a spiral spring 101 surroundine` the arn'iature. Wrhen magnet 97 is energized. a roller 102 on the upper end ot arm 99 engages and Eorces down a plate 103. Plate 103, seen endwise in Illia. 1i is a dat plate which extends the length ot the carriage so that regardless of Where the carriage may be along' the line7 the relation ot roller 102 to the plate 103 is the saine. Plate 1.03 is attached to a rod 104tniroted .in a frame 105 at each end ot the carriage, only one 'frame appearing in Fig. 1. @n the ond ot the rod 10d is an arm 106 (see lligr. 9) carrying a paWl 10il which is normally held down anjainst a stop-pin 109 by a spring-,1; 110. The stop-pin 109 serves to hold the paWl 167 clear ot the teeth ot the ratchet Wheel 168. While in its normal position. llhen the magnet 9T is energized. the pawl 167 engages a tooth on the ratchet Wheel 108 and rotates it and the platen 119J until the arm 10i' strikes the stop-pin 111 which holds it down between two teeth; at the same time, the curved end ont the arno prevents the rno mentum f' platen carrying it too far. To ret Y .5afeller in its proper position and insure even spacing between lines, an arm 113 carries a roller 114 which centers the ratchet wheel 103 between two teeth under the tension of a spring 115 half the diameterI of pinion 73, therethe guide rack 113 moves half as fast Rael; ''l is held down against earings by a spring clamp 120 and 121 Rack 'T4 is not only free to mere longitudinally, but to rock slightly on the halls 11T and under the roller 121 due to 'f .founded upper face of rack 74, this permits the front of the carriage to be raised and lowered, i. e., lifted about balls 11T as a pivot. At the front of the carriage is a roller 122 (see Fig. 1) which engages lifting bar 123. A guard 124 (see Fig. 1) prevents the carriage leaving the rail. Lifting bar is carried by a pair of arms 125 (only one of which 1s shown 1n Fig. 1)

attached to either end of a shaft 126. lVhen it is desired to shift the carriage from letters to figures, a magnet 127 (see Fig. 4) is energized through the closing of contact springs 123, 129 (see Fig. 13), which is brought about in a manner similar to the selecting of the line feed or of the carriage return, and which operation will not therefere be described. )When the armature 123 is pulled dewn, it first unhooks a safety latch which is provided as a guard against accidental shifting of the carriage by the operator. Referring to Fig. 10, the upper end of the armature 12S is connected to a lever 129 by a. pin 128m. The lever 129 rocks on pivot 130 from its normal position in which an upper jaw 1291 is held against shaft 126 by a spring 131 until a lcwer jaw 129c strikes the shaft 126. In this position the hook '129a is released from the bracket 132 on rail 116. Further movement of the armature 12S results in rocking the two arms 12.5 to lift or shift the carriage which rests on lifting bar 123. Referring to Fig. '1, attached to the shaft 126 is an arm 133 normally resting against a screw 134 (shown in dotted lines). A rocker 135 pirated on a pin 136 carries a plate .137, shown in dotted lines. lllhen the carriage is moved into the shifted position, the berelle(v face 133a of the. lever arm 133 forces the plate 13? down until it passes the plate,

when the lat-ter drops in behind and retains the arm 131:5, thereby retaining the carriage in the shifted position after the magnet 127 has been deenergized. It will be noted in Fig. 10, that a pull on the solenoid armature 128', due to the free play between jaws 129D, 129u and shaft 126, lirst releases hook 129L from bracket As soon, however, as lower jaw 129c engages shaft 126 from below, members 129 and 125 act as a unit double-armed lever, rocking on shaft 126, and the pull on armature 12S results in the lifting of lifting bar 123 and the shifting of the carriage from lower-case to upper-case position. On the deenergizaton of sclenoid 12T, and the return to normal of armature 128, latch 12S)a will reengage bracket 132, so as te again prevent accidental shifting of the carriage. A locking circuit also preferably provided for the n et 12T comprising an adjustable screw 12. and cooperating contacts 1271, 127c and as this locking circuit is closed and opened in the same manner as that. already described in connection with the sixth impulse magnet 2l, Fig. 5, the same need not be more fully described.

lli/hen it is desired to return the carriage to lower-case position, a predetermined pull `bar 13S (F ig. 1) is selected. This rocks the arm 135 on shaft 136, disengages plate 13T from lever arm 133 and allows the carriage te return.

Means for manually releasing the carriage from figure shift is also provided, Fig. 2, and comprising a push button 139 which projects through a hole in the frame of the machine. It is connected by means of a rod 140 to a bell crank lever 141 pivoted at 142. A spring 143 holds the lever in its normally retracted position. lVhen the button is pressed, the lever 141 strikes a iirnvnwardly projecting piece 144 attached to the pull bar 13b and rotates the rocker arm 135 to release the carriage, as already described.

Signal bell.

Referring to the circuit diagram, Fig. 13, a magnet 145 has an armature 146, which, when the magnet is energized, strikes a gong l-l-. Normally a pair of contacts 148, 149 are closed forming a short circuit around the magnet 145 and affording a path of low resistance from the battery to the space magnet 66 whenever the. contacts 64, 65 are closed. lWhen one of the type bars, such as the .l letter bar, is operated, and the carriage is shifted, a combination of movements occurs (to be described later), which separates the contacts 148, 149, and thereby places magnet 145 in series with magnet 66 while contacts 64, 65 are closed. The result et this circuit change is to energize magnet 145 and strike a single blow on the gong -llO 147, While the added resistance or" magnet 145, in series with magnet 66, 71, is 'sufficient to prevent the latter iroro overcoming the tension of its armature spring 71, and thereby prevents spacing.

Referring to Figs. 2, l and 12, 159 is an extension or one of the pull bars, here shown as the letter J pull bar, hinged to a bell cranlr lever 151, which roelrs onla stud 152. At its toi-Ward end is a longitudinally adjustable piece lililhenever the l p ull bar is selected and actuated, the motion transmitted to bell crank lever 151 causes a downward movement of part 153 forming a cam. lt the carriage is in the letters position, and theretore the letter d is to be printed, the cam 153 passes by a beveled block oit insulating` material 1511, attached to contact spring 148, and does not disturb its contact with spring 119. lt, however, :it is desired to give some s' Vial by ringing the bell 117, the carriage is first shitted and then the d' pull bar selected. rttached to the arm 133 are the two contact springs 14:8, 119, insulated therel'rom by a block 156. The part is merely a guard to protect the spring 148 from injury. Noir when the carriage is shifted, the arm 136 carrying the springs 148, 1419 is moved into such relation to part 153 that when J pull bar is selected, it strikes the beveled bloclr 154- and forces the contact spring 14:8 away from 141-9, and the bell is thereupon rung, in the manner already described in connection With circuit diagram Fig. 13. When this operation takes place, the cani 153 engages a horizontal projection 155a ot the member 155 and prevents operation of the J type bar.

Habbo/1t feed 'nwo/miriam.

'llie operation or the ribbon :feed is as follows: Referring to Figs. 1 and 2, the ribbon 161 is vlied alternately from tivo spools 157 and 158, which are carried at the upperends or vertical shafts 159 and 160. irrt the lower ends of these shafts are ratchet Wheels 162 and 168. Opposite each ratchet Wheel is a pair of paivls 16d, 165, 166 and 167. Retaining paivls 165 and 167 may rotate through a small arc of a circle about their stationary pivot points 168 and 169. Opere ating pavvls 1611 and 166 have both a rotating motion, like paivls 165 and 167, and a longitudinal motion which is imparted to them by virtue or their being pivoted at 179 and 171 on radial arms 'fastened to the shaft 172. @hait 172 has an oscillating motion imparted to it by magnet 16, through the shaft L18, arm 1,73 secured on said shatln bar 174 pivoted thereto and to an arm 17 5 (see Fig. 1). .drm 175 is not lirmly at tached Vto sha'ltt 172, but imparts its motion thereto through a spiral spring 176 and an arm 177 rigidly attached to the shaft (see maaien TEig. 2)'. rl`his Flexible transmission is for a purpose which will appear later. 1t will be observed that, While parvls 164; and 165 are in operating relation to ratchet Wheel 157, parvis 166 and 167 are held out of engagement with ratchet Wheel 158 by pins 178 and 179 in the transverse bar 186, and vice versa. Thus, While the ribbon is being Wound up on spool 157 by the paivl 164-, it is free to unwind from spool 158. lllhen he ribbon becomes fully univound from spool 158, the bar 180 A is automatically n'ioved toward the spool 158, so that a pair ot pins 181. 182 push the paivls 16d and 165 out ot engagement with ratchet Wheel 162, and pins 178 and 179 allo'iv paivls 165 and 16T to ei'igage the teeth on ratchet Wheel 16S and rotate the spool 158. This automatic reversal is brought about in the tolloiving manner, Referring to Fig. 1, in the hub 18?; at the upper end ot' the shatt 159 is a slot t'or the reception ot a thin 'flat lerer 1811 which is pivoted on a pin fr spring 186 holds the lover in the position shown when the ribbon is univound, but when the ribbon is Wound on the spool 157, it forces the upwardly projecting part 181 inwardly, .so that the arm 18d lies close to the sha'it above and below its pivot. 1n. the path or arm 1841: is an arm 187 attached to a vertical shaft 188 which carries an arm 189 connected by a pin to a bar 190. The bar 190 carries a pin 197 which extends through a slot 191u in a lever arm 191. Lever arm 191 has longitudinal motion imparted to it by a radial arm 196 secured on the shatt 172, the connection being such, however, that lever arm 191 is not oscillated by the movement o1 the arm on which it is mounted.. rlflie arm 191 is bent down at the end, as at 191, and this downward projection engages one or the other of tivo lugs or 196 on a lever arm 192. rrin 192 is pivoted on a stationary pin 19st and when the arm 1,91n strikes a lug 195 or 196, it rocks the arm 192 and tlm gli a connect ing pin 199 inoves the bar 181) longitudinal ly for the purpose already described. ln the 'foregoing description reference has been made to levers 18d and 187. lt 'Will be seen in Fig. 2 that similar levers on the other side ot the machine are associated with the spool 158 and are adapted to impart motion to the bar 190 in the. opposite direction Yfrom the parts assr'iciated With spool 157. The position ot the various parts associated with the ribbon pad, as siown in the drawing,v are illustrated in the positions which they occupy when the reversal ot the ribbon feed has just been completed. lThe ribbon having unvvound to the last turn release, the lever 184 which, under the tension of the spring 186. moves out into the path olt the arm 187 which at this time occupies the position with relation to the spool hub, shown lllf) at the top of Fig. 2, in connection with spool 158. lVhen the last turn on the spool is univound, the arrn 184 forces the arm 18T into the position, shown at the bottom ot Fig. 2. with the result already described.

The function of the spring 176 is to permit of an independent adjustment of the ribbon-feed mechanism and the mechanism which operates the bail l1, any difference in the adjustment of the tivo is taken up fn the spring 1TB. lt also serves to preient execs sive stress on the parts of the ribbon-feed mechanism. should any of its parts, or the ribbon itself becofne caught.

dovvnwardly from the spools and away from the front of the platen, the purpose ot which is to make the Writing on the paper visible.A

`Whenever a letter or character is to be Written. the ribbon must be raised in advance of the approaching type bar 1, so that it will be interposed between the paper and the character on the type bar. The universal bar 5G carried by the arms 54 and 55 is pushed back by the operation of type bars 1, in a manner already described in connection with the spacing. The bar 56 has an upwardly extending arm 198 (see Fig. 1) provided with a slot 199 Which serves as a guide for a pin 200a in a rocker arm 200 The rocker arm 200 is pivoted on a pin 203 on an arm 201. lVhen the slotted arm 198 is pushed back by the engagement of the shoulder la on a type bar 1 with the projection 56a on the bail 56, the rocker 200 is rotated about the pin 203 and raises the arm 202 and with it the ribbon, inter-posing the latter between the paper and the approaching type bar. lVhen the carriage is shifted for the purpose of Writing figures which are higher up on the type bars than letters. the ribbon must be raised higher than for the letters. This is effected by actuating` arm 201 scoured on the shaft 126, which lifts the rocker 200 bodily and in the shifted position supports the rocker 200 on pin 203 at a higher level.

Details relating to the carriage.

ln Fig. 4 is shown a spiral spring 204 ha'. ing one end attached to the frame 205 and the other enfl to an arm 125 secured on the shaft The function of this spring is to support a part of the Weight of the cari ir re on the rail 128. Fig. 1. and make it easier for magnet 12T to shift the carriage. it also reduces the violence of the blow as the carriage falls when released by the rocl1er 135.

.liso in Fig. 4 is shown a dash pot, consisting of a cylinder 20G, a piston 20T and a wiring 208. This dash pot serves as a shock worher to reduce the force of the blow `which the carriage strikes when it returns to the beginning of a. line. Then the carriage is some distance from the beginning ot' a line, the piston 207 is in the position shown7 but when it is released a lug 207b on the carriage strikes the projecting rod 20TH and drives the piston into the cylinder coinpressing the spring 208 and also the air confined in the cylinder` and thus retards the speed of the returning rarriage and prevents shock.

Umvrz'af/e construction.

front view of the carriage is shown in ig. 3 and certain enlarged details in Figs. and 9.

Referring to Fig. 3, the platen roller 200 has a shaft 210 supported by bearings in the two end plates 105, 105. it one end of the shaft is a knurled hard rubber knob 211 and at the other end a crank 212 for conveniently turning the roller. larallel with the large roller 209 are several pairs of rollers arranged on either side of the platen 209, and here sho-wn as three pairs ot' such rollers 21S. and 213 for holding the paper firmly and feeding it evenly, as the large roller is turned. The sinall rollers are held against the lar-ge roller by a spring 218 (see enlarged detail Fig 8). Une end of the spring 218 is fastened to a collar 216, to which the arin 216 is secured and which is free to rotate on shaft 220. The other end of spring 218 is attached to a collar 219 which is secured to shaft 220. Shaft 220 is free in its bearings at either end. The spring 218, therefore, presses the rollers 218 and 213 against the platen equally.

Above the platen roller 200 is a metal strip 221 With a knife-edge at the rear against which the paper may be torn oil'1 smoothly and evenly from time to time as the messages are fed up from the roller.

Referring to the enlarged detail Fig. i), the metal strip 221 held by an arm 222 'it each einh which is pivoted on a rod 223. .i spring presses against the outer eorner 222 of the arm and holds the knife and attached clip down to the platen roller 209. il roller (see Fig. 3) at each end rests upon the platen and, when there is paper in the carriage, upon the paper and holds the strip 221 a short distance away from the roller 209. ln putting paper into the carriage it is desirable to raise the strip 221 with its clips and rollers 225 up from the roller which mayv be done as the end pieces may rotate the rod 2253 back until the corner 222"L falls into the notch 224u and retains it in that. position.
