- the selector unit is shown in Figs. 2, 3, 4 and 5, and comprises a base plate 34, upon which there are mounted frame plates 35 and 36, between which are arranged the selector magnets 22. These magnets are provided with armatures 37, pivoted at38 and have their ends 39, remote of the magnets, extending to positions beneath the lower arms 40, of the pawls 41, pivoted at 42, to the vertically displaceable pawl carrier 43.
- the ends of carrier 43 pass through slots in frame plates 35 and 36, and are provided with.
- rollers 44 and 45 adapted to be engaged by cam faces 46 and 47 ,of a longitudinally sli'dable actuating bar 48.
- One end of bar 48 carries a roller-49, adapted to be engaged by a wedge head 50, at the end of a rocking arm 51, secured to an operating shaft 52, whereby a thrust roller 53, assists head 50, when engaging roller 49.
- a spring 54 tends to pull bar 48 toward the right, and'springs 55,-56, pull pawl carrier'43 downward.
- a latch 57 Associated with each of the pair of their arms 4O in the extreme low position pawls 41, there is a latch 57, pivoted on carrier 43 and connected to its proper pawlhy means of a spring 58.
- a stationary bar 59 supported in frames 35, 36, carries a tripartite lever 60 for each 'pawl 41, of which the downwardly projecting arms 61 and 62, are adapted to be engaged by the upwardly extendin arms 63, 64, of pawls 41, while an upwardly'extending arm 65, engages a recess 66, on the lower edge of a s idable selector bar 67.
- Selector bars 67 will remain in the position where last set until the position is changed in a succeeding selection, there being no normal position such as is common in the prior art.
- selector bars 67 are provided, on their upper edge, with grooves 68, for receiving the pull bars 69;
- the armature 37, of each magnet 22, is' provided with a downwardly extending arm 7 0, adapted to be engaged by one end of a latch 71, the opposite end of which is controlled within an elongated slot of a release bar 72.
- the bar 72 carries at one of its ends a dog 73, and near this end a second dog 74, the first to be operated upon by an arm 76, 9a of armature 28, and the second one to engage a latch 75, for holding another arm 78, of armature 28.
- a helical spring 79 holds armature 28 away from its electro-magnet 27, and another spring 80 holds latch 75 toward arm 78.
- Individual springs 81 hold each of the latches 71 toward the arms 70. The normal position of parts, before any selection takes place, is shown in Fig. 3.
- Bar 48 is in its extreme left position, under tension of spring 54, and its dog 84 is held by pawl 85.
- the armature 28, of magnet 27, is prevented to occupy its attracted position, through the locking of arm 78, by latch 7 5, under tension of spring 80.
- the pawl car-- rier 43 is in its lowermost position under tension of springs 55 and 56, and rollers 44, 45, rest in cam faces 46, 47, of operating bar 48.
- Pawls 41 are all tilted to the right,
- latches 57 are tilted to the right *and their lower locking faces in engagement. with the upper locking faces of the right hand extensions of pawls 41, under tension'of connecting springs 58, Fig. 3.
- a spring 77, Fig. 1 holds armature 37 of each selector-magnet 22 away from the magnet core.
- Stationary bar 59, carrying the tripartite levers 60, is provided with lugs 83, adapted to be engaged by a wedge f'aceof latches 57.
- Actuating bar 48 is providedwith a dog84, adapted to be engaged by pawl 85, secured to shaft 86.
- a crank arm 87 connects this shaft, byv means of link 88, to crank arm 89, of shaft 90, of armature 28 I It will be apparent that until a selecting .impulse is receivedby at least one of the magnets 22. armature 28 will be mechanically locked by pawl 75 and no operation will occur in the printer; the first act in the reception of signals from the transmit: ter is the selective energization of magnets 29, resulting in the attraction of their re.- spective armatures 37. The rear ends 39, of these armatures, are lifted by whatever magnets received an impulse, and the corresponding ,pawl 41 is tilted to the left. Pawl 41 and its latch change their respective locking faces and occupy the position, shown in Fig.
- Pawl carrier 43. is lifted by its rollers 44 and 45, rising from the lowest point of cam faces 46 and 47 now moving under them to the right, to the upper edge of cam bar 48, resulting in a tilting to the right of vertical lever arm 65, of tripartite lever 60, and a corresponding shifting to the right of one or more of the selectedselector liars 67.
- the wedge faces of latches 57 engage restoring lugs 83, forcing the latches 57 to the right in Fig. 4 about their pivots until the actuated ones of the pawls 41 are freed fromengagement with the correspond ing ones of latches 5 and are ⁇ permitted to restore to unactuated position asshown in Figs. 3 and 4.
- selector bars 67 are so arranged that, un-
- roller bar 95 normally located underneath lugs 97, prevents pull bars 69 to fall in notches 68 of selecting bars 67.
- roller 95 aligns with arches '98 and permits a-pull bar ,69, that finds its notches 68 aligned, to drop in the aligned notches, whereby its lug 97 enters the path of movement of the universal bar 96,50 that bar 69 is forcibly moved or actuated. In this manner. it will be apparent that the pull or actuating bars 69 are permitted'to drop easily into place, thus obviating objectionable noise and shock 1 common in usual prior art machines.
- the universal bar 96 co pletes the printing stroke on'its forwar movement, and re. mains in engagement with the pull barnntil a printed impression has been made. Pressure is therefore applied to the' type-bar 1 until a printed impremion has been made on the paper. In previous printers it has been commonly the-custom to cease application of pressure to the type-bar before impression wasmade Dependence was placed upon inertia of the moving parts to complete the stroke and print. This results in ob jectionable shock. clatterand strain due to rapidly repeated blows.
- Each of the pull bars 69 is linked to a vertical arm 99, by means of a pin 110 and the vertical arms, in turn, are linked to type bars 112, the latter pivoted at/ 113 and normally resting on type bar pad 114.
- Pull bars 69 are returned to normal position by means of helical springs 118.
- any one of the type bars actuates the spacing mechanism, as, follows:
- Each of type bars 112 is provided with a shoulder 119, which, when the type bar is raised, engages universal bar 120, pivoted at 121 to vertical rocking supports 122, Figs. 1' and 8, normally biased by spring 123.
- One of the supports 122 is connected, by means of link 124, to lever 125, secured at its upper end to shaft 126. The free lower end of lever 125, Figs.
- pawl lever 127 engages pawl lever 127, pivoted at 128, and in moving it, causes pawl 129 to glide over one tooth of ratchet 130 and engage the same so that on the return movement of lever '127, ratchet 30 will be advanced the distance of one tooth.
- a retaining pawl 131 pivoted at 128 independcntly of lever 127 is normally held in engagement with ratchet 130 by means of a spring interposed between pawls 129 and 131 which also holds "pawl 129' in engagement with ratchet 130. It will accordingly be seen that pawl 131 prevents backward rotation of the ratchet 130.
- An arm 132 is pivoted to lever 127 at 133 and is bifurcated at its end, to engage arm 134, fastened to rear operating shaft 135.
- This shaft is rocked by rocker arms 94 of front operating shaft 52, connecting rod 136 and crank arm 137 of shaft 135.

A CORPORATION OF DELAWARE.
PRINTING TELEGBAPHY.
Application filed January 21, 1922. Serial No. 530,880.
T0 1111 whom it may concerm, V, p Be it known that ED\YA.RD 'E. KLEIN- sonzum'r, a citizen of the United States. and
resident of Brooklyn. in the countyof Kings 5 and State of New York, has invented-cer 1 tain Improvements in Printing Telegraphy,
of which the following is a specification.
This invention relates to printers of the pageor tape-printing type for use in print- The ideal printer would.
to lug telegraphy.
be the one in which the mental functions of the human operator are performed by the electric current, while the mechanical func tions'are brought about by suitable power mechanism.
A copending application, Serial Number 1 390,598, filed June 21, 1920, discloses a telegraph printer in which an eliort is made to approach this ideal. This application in cludes principally improvements in typewriteractions, complying to the peculiar requirementsof a telegraphic type-bar printer and its various functions."
The present invention utilizes typewriter actions similar to those disclosed in the foregoing application, but operated by a single common power magnet, and controlled by electro-magnetic means actuated by electmc impulses originating at a remote statlbn. It
Blf'is distinctive from telegraphprinters, op-
erated by constantly drivenwpower mecha nism, in that a single electro-magnetis employed for bringing about all the mechanicalfunctions of the dilferent typewriter ac: "tions, which electro-magnet isnormally deenergized, and is energized only momentarily' for each of the difi'erent printer operations. The advantages of the employment of such. an electro-magnet, preferably in the form of a solenoid, include the feasibility of using either direct or alternating current, and. the extreine simplicity of electriccontrol of the different mechanical! operating devices. Another feature of the invention consis in the performance of the various typewriter functions by positive operation, including the restoration of operated parts.
Af further feature refers to the arrangement of selector bars that remain in the pc- ,sition to which they are moved, and are moved to dill'erent positions only by -positive action. They may be arranged in group positions of predetermined characteristics, and remain in the selected group position, until regrouped, without returning to nor mal. position. J W

Any other generator of electrical energy,

tor, indicated, in general, at 18. This distributor includes a ring 19, consisting of a plurality of insulated segments or contacts 20, of which there are five in the well known 5 Baudot printing telegraph. system, to which the present invention is peculiarly adapted. A rotating brush 21 bridges the rings 17 and 19. The contacts 20 are connected, respectively, to selector magnets 22, and included in the circuit of battery 13. Thecir-' cuits of selector magnets 22, therefore, are controlled by contacts and rotating brush 21 and if, when this brush glides over a contact, armature 12 of line magnet 11 is in.
V 2 electrical energy 13. Brush 23 bridges ring 24 with another ring 25, having a single insulated segment 26, the sixth impulse contact, with which brush 23 is brought into engagement, after brush 21 has passed all five contacts 20 of ring 19, and the selecting impulses have been received. Contact 26 is connected to a magnet 27, which is also included in; the circuit of battery 13, and its armature 28 is adapted to close ja contact springs 29 and 30, controlling the circuit ofa single operating solenoid 31 and its source of energy. A capacity 32 and a resistance 33, are preferably bridged between contacts 29 and 30, in the usual way,
4 in order to prevent sparking.
Selector unit.
The selector unit is shown in Figs. 2, 3, 4 and 5, and comprises a base plate 34, upon which there are mounted frame plates 35 and 36, between which are arranged the selector magnets 22. These magnets are provided with armatures 37, pivoted at38 and have their ends 39, remote of the magnets, extending to positions beneath the lower arms 40, of the pawls 41, pivoted at 42, to the vertically displaceable pawl carrier 43. The ends of carrier 43 pass through slots in frame plates 35 and 36, and are provided with. rollers 44 and 45, adapted to be engaged by cam faces 46 and 47 ,of a longitudinally sli'dable actuating bar 48. One end of bar 48 carries a roller-49, adapted to be engaged by a wedge head 50, at the end of a rocking arm 51, secured to an operating shaft 52, whereby a thrust roller 53, assists head 50, when engaging roller 49. A spring 54, tends to pull bar 48 toward the right, and'springs 55,-56, pull pawl carrier'43 downward. Associated with each of the pair of their arms 4O in the extreme low position pawls 41, there is a latch 57, pivoted on carrier 43 and connected to its proper pawlhy means of a spring 58. 1 J
A stationary bar 59, supported in frames 35, 36, carries a tripartite lever 60 for each 'pawl 41, of which the downwardly projecting arms 61 and 62, are adapted to be engaged by the upwardly extendin arms 63, 64, of pawls 41, while an upwardly'extending arm 65, engages a recess 66, on the lower edge of a s idable selector bar 67. Selector bars 67 will remain in the position where last set until the position is changed in a succeeding selection, there being no normal position such as is common in the prior art. In the, embodiment shown, employing the Baudot code, there are five such selecting bars, one for each selector-magnet 22, the functions of which are well known in the printing telegraph art. The selector bars 67 are provided, on their upper edge, with grooves 68, for receiving the pull bars 69;
The armature 37, of each magnet 22, is' provided with a downwardly extending arm 7 0, adapted to be engaged by one end of a latch 71, the opposite end of which is controlled within an elongated slot of a release bar 72. The bar 72 carries at one of its ends a dog 73, and near this end a second dog 74, the first to be operated upon by an arm 76, 9a of armature 28, and the second one to engage a latch 75, for holding another arm 78, of armature 28. A helical spring 79 holds armature 28 away from its electro-magnet 27, and another spring 80 holds latch 75 toward arm 78. Individual springs 81 hold each of the latches 71 toward the arms 70. The normal position of parts, before any selection takes place, is shown in Fig. 3.
and in contact with the rear extensions of the unattracted armatures'37, latches 57 are tilted to the right *and their lower locking faces in engagement. with the upper locking faces of the right hand extensions of pawls 41, under tension'of connecting springs 58, Fig. 3. A spring 77, Fig. 1, holds armature 37 of each selector-magnet 22 away from the magnet core. Stationary bar 59, carrying the tripartite levers 60, is provided with lugs 83, adapted to be engaged by a wedge f'aceof latches 57. Actuating bar 48 is providedwith a dog84, adapted to be engaged by pawl 85, secured to shaft 86. A crank arm 87 connects this shaft, byv means of link 88, to crank arm 89, of shaft 90, of armature 28 I It will be apparent that until a selecting .impulse is receivedby at least one of the magnets 22. armature 28 will be mechanically locked by pawl 75 and no operation will occur in the printer; the first act in the reception of signals from the transmit: ter is the selective energization of magnets 29, resulting in the attraction of their re.- spective armatures 37. The rear ends 39, of these armatures, are lifted by whatever magnets received an impulse, and the corresponding ,pawl 41 is tilted to the left. Pawl 41 and its latch change their respective locking faces and occupy the position, shown in Fig. 4, the upper locking face of latch 40 now engaging the lower locking face of pawl 41. The armature of the magnetQfirst energized, locks its lever to latch 71 which moves bar 72 to the right and causes the disengagement of latch from arm '7 8, by means of dog 74. Magnet 27 is now ready to receive its energizing impulse, called the sixth impulse, as soon as commutator brush 23 reaches segment :26. of the distributor head, after brush 21 has passed all five segments 20, and thereby transferred the incoming selecting impulses to magnets 92 When: the impulse over segment 26 is received at magnet 27, armature 28 is attractder the action of selecting magnets, certain predetermined notches will be aligned, capable to receive the front eiid of pull bars 69, of tlie typewriting mechanism. 1, p
' Simultaneously with the movement of cam 70 bar 48, arm 7 6 of armature 28 pushed. dog
Operating mechanism. a
When magnet 27 is energized and its armature 28 attracted. as stated before, con-. tacts 29, 30, were operated to close the circuit for solenoid 31. This solenoid is provided with a core 91, which rocks operating shaft 52, by means of link connection-92 and an arm 93, keyed to shaft 52. Theopcrating frame, comprises rocker arms 94 and two spaced-apart parallel bars 95, 96. connecting the same, of which bar is pref erably roller-shaped and normally located beneath lugs 97, formed on the lower side of pull bar-s69, as rear extensions of arched, in consequence thereof pawl 85 is lifted shaped recesses. 98, while 96is a universal from dog 84. and cam bar 48 pulled to the extreme right by spring 54. Pawl carrier 43. is lifted by its rollers 44 and 45, rising from the lowest point of cam faces 46 and 47 now moving under them to the right, to the upper edge of cam bar 48, resulting in a tilting to the right of vertical lever arm 65, of tripartite lever 60, and a corresponding shifting to the right of one or more of the selectedselector liars 67. J After the shifting of the selector bars by the prongs 63 and 64 of the pawls 41 has been effected, the wedge faces of latches 57 engage restoring lugs 83, forcing the latches 57 to the right in Fig. 4 about their pivots until the actuated ones of the pawls 41 are freed fromengagement with the correspond ing ones of latches 5 and are} permitted to restore to unactuated position asshown in Figs. 3 and 4.
It will thus be seen that in case a selector bar has been shifted into selected position by a prior impulse and is selected again by a succeeding selecting impulse, no shifting of the bar is required. The pawls, however, of the non-selected magnets and having their pawl arms 64' e mont with right lever arms 62, will tilt levers 60 to the left and thereby restore selector bar-s67 to normal the art, notches 68 nomselected position.-
in selector bars 67 are so arranged that, un-
' i As now well known in bar, having a substantially rectangular edge, adapted to engage the lugs 97 and push any pull or actuating bar 69 forcibly toward the front of the machine.
The roller bar 95, normally located underneath lugs 97, prevents pull bars 69 to fall in notches 68 of selecting bars 67. As soon, however, as solenoid 31 rocks shaft 52, roller 95 aligns with arches '98 and permits a-pull bar ,69, that finds its notches 68 aligned, to drop in the aligned notches, whereby its lug 97 enters the path of movement of the universal bar 96,50 that bar 69 is forcibly moved or actuated. In this manner. it will be apparent that the pull or actuating bars 69 are permitted'to drop easily into place, thus obviating objectionable noise and shock 1 common in usual prior art machines. The universal bar 96 ,co pletes the printing stroke on'its forwar movement, and re. mains in engagement with the pull barnntil a printed impression has been made. Pressure is therefore applied to the' type-bar 1 until a printed impremion has been made on the paper. In previous printers it has been commonly the-custom to cease application of pressure to the type-bar before impression wasmade Dependence was placed upon inertia of the moving parts to complete the stroke and print. This results in ob jectionable shock. clatterand strain due to rapidly repeated blows. By, use of the Each of the pull bars 69 is linked to a vertical arm 99, by means of a pin 110 and the vertical arms, in turn, are linked to type bars 112, the latter pivoted at/ 113 and normally resting on type bar pad 114. The printing face of each type bar 112, at the end of the printing stroke, enterstype bar guide 115 and forces type ribbon 116 against the printing page, supported on printing platen 117. Pull bars 69 are returned to normal position by means of helical springs 118. There is a pull bar provided for each letter of the alphabet, numeral or figure, as now well known in the art, and for each function to be performed by the printer.
Spacing mechanism.
The operation of any one of the type bars actuates the spacing mechanism, as, follows: Each of type bars 112 is provided with a shoulder 119, which, when the type bar is raised, engages universal bar 120, pivoted at 121 to vertical rocking supports 122, Figs. 1' and 8, normally biased by spring 123. One of the supports 122 is connected, by means of link 124, to lever 125, secured at its upper end to shaft 126. The free lower end of lever 125, Figs. 7 and'9, engages pawl lever 127, pivoted at 128, and in moving it, causes pawl 129 to glide over one tooth of ratchet 130 and engage the same so that on the return movement of lever '127, ratchet 30 will be advanced the distance of one tooth. A retaining pawl 131 pivoted at 128 independcntly of lever 127 is normally held in engagement with ratchet 130 by means of a spring interposed between pawls 129 and 131 which also holds "pawl 129' in engagement with ratchet 130. It will accordingly be seen that pawl 131 prevents backward rotation of the ratchet 130. An arm 132 is pivoted to lever 127 at 133 and is bifurcated at its end, to engage arm 134, fastened to rear operating shaft 135. This shaft is rocked by rocker arms 94 of front operating shaft 52, connecting rod 136 and crank arm 137 of shaft 135. At the time that bifurcated arm 132 is moved towards arm 134, the latter is rocked away from it, through the actionof solenoid 31.
Vhen now this solenoid is deenergized, all the parts operated by its core armature are returned to-normal position, by means of spring 138. When the parts are thus returned, arm 134 engages forked arm 132, moving lever 127 and causing pawls 129,
131, to rotate ratchet 130 the distance of one one end of which is secured to cylinder 143 and the other end to shaft 139, so that when the spacing mechanism is operated, spring 144 is wound up and, on its release, carriage 142 is returned to its start position.
Shifting mechanism.
The shift mechanism for printing different sets of characters, represented by the upper and lower case of the typewriter keyboard, is operated'by'means of rockin arm 145, secured to shaft'--;135,- Fig: 11, eing formed with two notches 146 and 147. The shift mechanism comprises two rocking arms 148, pivoted on to shaft 126, and bar 149, carried at the outer ends of arms 148. This bar is located underneath roller 150, of carriage 142. One of the arms 148 is provided with front extension 151, to which is pivoted, at 152, latch 153, the upwardly extending arm of which is provided with tooth 154, adapted to engage stationary lug 155, and normally to prevent the operation of the shift mechanism. L
A spring 156 is connected to pin 157, of
of arm 159, of extension 151. The spring 156 normally holds tooth 154 in engagement with lug 155. A connecting rod 160 is pivwithin which is enclosed helical spring 144,
I latch 153, and to a second pin 158, at the end oted to latch 153 and its lower free end is provided with pin 161, adapted to engage either ofthenotches 146 or 147, of bent arm 145. Intermediate its pivot and free end, connecting rod 160 has a pin 162, adapted to engage slot 163, of arm 164, which is se- 1 cured to shaft 165, having its bearing in support 166. Also secured to shaft 165,.Fig. 7,
is arm 167, provided with pin 168. This pin provided with downward extension 171 and,
when the pull-bar is moved to the right, as viewed in Fig. 11, L- shaped latch 172, engages behind extension 171, under tension of spring 173, surrounding ivot 174 of latch 172, and retains pull-bar 1 0 in its forward position. 7
The movement of pull-bar 170, puts arm 167 and shaft 165 under tension, through the action of spring 169, Fig. 7, and, as soon as bent arm 145 has been rotated sufficiently, to bring its notch 147 opposite pin 161, the
'lower end of connecting rod 160, snaps to the right to bring pin 161 into notch 147.
Then, when shaft 135 is rotated in the op posite direction, by spring 138, arm 145 pulls connecting rod 160 downwardly. When latch 153 is its normal position, as shown in Fig. 11, there is a certain amount of lost motion between latch. 153 and arm 148, to the extension of which it is pivoted, so that the first downward pull of connecting rod 160 releases tooth 154 from lug 155. The front end of latch 153 then restsagainst shaft 126, and latch 153, in conjunction with arms 148, move as a; double-armed lever-unit about shaft 126 and cause bar 149 to lift roller 150 and carriage 142 for upper case printing.
An arm 175, Fi 11 and 12, is secured to shaft 126, and w en the shaft ,is rocked,
as described, the lower end 176, of arm 175', engages behind adjustable latch plate 17 7 ti-ltably resting on fulcrum edge 178, and secured by means of set screws 179 to arm 180 which is pivoted at 181, while pin 182at the lower end of/arm 180, engages the notched end of the shift-release pull-ba r-183, thereby retaining carriage 142 in its shifted sition. A pair of set screws 184, 185, limit ing all parts to normal position. In order to restore carriage 142 to its normal lower case position, it requires a separate code Signal which brings about the operation of shift-release pull-bar 183, Fig. 12, which, being thrown forward, rotates am 180 about its pivot 1.81, releases latch 17 6 of lever 175,
from latch plate 177, thereby permitting carriage 142 to drop to its normal lower case position.

The carriage return pull-bar 189, Fig. 15, is not moved longitudinally, like the other pull-bars, but sim ly tilted about a pivot located midway its ength, for the reason that universal operating bar 96 is provided with slot 190, which comes beneath this pull-bar, when universal bar96 is rocked to the right,
as viewed in Fig. 15, whereby pull-bar 189 pulls connecting rod 160. The upper end merely drops into the aligned notchesof selector bars 67. .Boller 95 glidin along arch 98 causes the forward end of pu l-bar 189 to drop into ,the aligned notches, its rearend -191 is lifted and, being in engagement with bell crank 192, Fig. 14, rocksthe same about its pivot 193. This bell crank carries'at the end of its second arm, piif 194, which engages upper arm 195 of a double-armed leter, pivoted at 196. The lower arm 197 of this, lever is formed with detent 198, Figs. 14 and-17, adapted to engage shoulder 199, formed on disc 200, secured to shaft 135. Pivot 196 is mounted at the end of arm 201, secured to shaft 202, on which is also fastened forked member 203, the forked ends of which are located underratchet 130 and are in contact with the lower face thereof.
This lower face of ratchet 130 carries crown toothed member 204, adapted to engage the teeth of a similar crown-toothed member 205, fixed to shaft 139.
-When the energization of solenoid 31,.Fig.
1, causes the rocking. of shaft 135, in an 200 engages detent'198, pulls the samedownward and rocks arm 201, causing the lifting of the; prongs of forked member203. This member, in turn, raises ratchet 130 and dis engages the teeth of clutch-204 from those of clutch 205, permitting shaft 139 to rot to under the influence of spring 144 and t us returning the carriage 142, to its ihitial position, through the rotation of inion 140, in mesh with rack 141. The of shaft 202 causes arm 206 to swing to the right,
as viewedin Figs. 14 and 16, permitting itv to become engaged by notch 207, on latch 208, thereby ho position.
ding ratchet 130 in raised" anti-clockwise direction, shoulder 199 of disc 1 This latch 208 is linked, by' means of connecting rod 209, to lever arm 210 carried on shaft 211, Fig. 14. A lever am 212, secured to shaft 211, is adapted to engage pin 213 carriedat one end of. carriage 142, Figs. 7 and 10. When latch 208 engages lever arm 206, lever arm 212 is rotated in a clockwise direction about its pivot 211. When new carriage 142 approaches the end of itstravel :to the 'l eft,'Figs. 10- and 14, pin 213 engages the end of lever- 212, thereby lifting con: necting rod 209 and latch 208, whereby the latter releases arm 206 and permits ratchet 130 todrop and to re-engage toothed clutch . members 204 and 205 to normal relation.
Law feed mechanism.
The line feed-is brought about by the rock ing of two-notched bent arm 214, secured" to shaft 135, Fig. 1. The parts associated with this'arm are preferably operated in a similar manner, as the parts operated by arm 145 ofthe shift mechanism, shown in Fig. 11, The movement of arm 214 pulls connecting rod 215, in the same manner, as arm 145 end of guide members 217, which engages plate 220, extending the entire length of the carriage, being suitably pivoted on shaft 221,
as shown in the above mentioned application.

In a printing telegraph receiver, a plurality of type bars, corresponding actuating bars, a set of longitudinally movable, notched permutation bars, a corresponding set of actuating devices operative in different conditions to shift said permutation members in opposite directions, to align the notches thereof and thereby selectively control said actuating bars, means for reciprocating said. actuating devices to effect the operation thereof upon said permutation bars, a common operating member for moving the selected actuating bars through the notches of the permutation bars to operate the corresponding type bars, and electromagnetic means controllingthe setting of said actuating devices in' response to received code combinations.
94. A. selecting mechanism comprising aset of notched permutation members, pivoted levers individual to said permutation members and connected thereto, a set of actuating devices operative in two different conditions upon said levers to shift the same and the corresponding permutation members in opposite directions, means for reciprocating said actuating devices to effect the operation thereof upon said levers, and electromagnetic means for selectively determining the operative conditions of said actuating devices in response to received code combi nations.
95. A selecting mechanism for telegraph receivers'comprising a set of notched permutation members movable in opposite directions to selectively align the notches thereof, a plurality of selectable members controlled by'the alignment of the notches of said permutation members, pivoted levers individual to said permutation members and operatively connected thereto, a corresponding set of transfer and storage devices for said levers, means for moving said transfer and storage devices through two different paths to tilt said levers and thereby move the corresponding permutation members in opposite directions and electro-magnetic means for determining the operative conditions of said actuating devices in response to received code combinations.
96. In combination in a printing telegraph receiver, a set of notched permutation members, a corresponding set of actuating members adapted to be set in response to received code combinations and each operative in two different conditions for shifting the corresponding permutation members in opposite directions to selectively align the notches thereof, printing means, a plurality of devices controlling the operation of said printing means, said devices being selectable by'lateral movement into the aligned notches of sald permutation members and operating means for successively shifting the saidactuating members to effect the operation thereof upon said permutation members, effecting the engagement of said controlling devices with said permutation members and the operation of said printing means.
