chinos, and the main object of the invention is to provide a simple and efficient construetion of the character s ecitied.

To the'above and ot 1er ends which will hereinafter appear my invention consists in the features o construction, arrangements vof parts and combinationsof devlces to b e herelnafter described andparticularly pointed out in the appended claims. 1

In 'the accompanying drawings wherein characters .indicate corre spending parts' in the various views, Figure I tion of l' is a' ver ical front to rear sectional view showin al suflieie'nt number of parts of one form o typewriting machine to illustrate m' inventionl in its embodiment therein. Fig. 2 is a bottom View of the same.

the forward side of the platen frame bear uponA the truck and su )ort the :platen frame. Pins l1 pro`ect ltlterally from the end plates of the aten frame and copcrate with upwar y irojecting ears 12 on the truck when the platen frame is swung back to the dotted line position, in order to -limit the backward movement of the platen frame and -sulpport it in its swung-back rpo sltion. vcy indrical platen a is supported to turn 1n bearings in the )laten frame and is moved with the platen rame during the swinging movement thereof.

Perforated guide plates 13 are supported o n the side lates l and receive key stems 14 of the printing -keys 15. The lower ends of the key stems are received in perforations 16 in a fixed horizontally disposed guide plate 1'? secured at its ends to theside plates 1 of the machine. The guide plates 13 and 17 thus constitute means for guiding the ke stems in their vertical movements. Enc

key stem 14 is connected by a laterally -projecting headed pin 18 with an angular type bar actuatinoV ever 19, the pin being received in a siaot 20 in the forwardly extending horizontally disposed arm of the lever. Each pin is carried by and projects laterally from a sleeve 21 connected to its key stem by a set screw 22. The angular levers 19 are pivoted at l23 to individua-l hangers 24 sc cured by screws 2 5 to a segment 26 fixed at its ends to the side plates of the machine.

Contractile restoring springs 27 are each .connected at one end to'an upright arm of an angular actuating lever and at its opposite end to a fixed plate 28. The upright arm of each an ular leveris pivotally connected to a pnl? link 29 pivoted at its rear end as at 30: to the heel of a type bar 31 pivoted at 32 to a type bar hanger 33 secured to a type bar segment- 84. The tvpe'b'ars are all supported at' their forward ends on a pad35 and move upwardly and rearwardly to strike against the front race of the platen a.-

`horizontally disposed llocking pla-te 36 los' is pivotally connected by shouldered screws 37 to the lower ends of parallel supporting links 38. pivoted on shon dered Screws 39 at the upper ends thereof to the side plates of themachine. This lockin plate is provided with perfor-ations 40 whic 1 when the lockin plate is in the normal position are adapte to register with the openin 16 in the lower fixed guide plate and wit the key stems which project therethrough as indicated in Fig. 2. From an inspection of Fig. 1. it will be seen that when the locking plate is in the normal position the parallel guide links 38 are disposed at a slight angle and atl'ord a horizontal forward movement of the locking plate to the position shown in Fig. 3 where the openings 40 are thrown out of register with the lower ends of the key stems and with the Guide o enin 16 in the fixed guide plate, thereby ringing the full body ortion ofthe locking plate opposite to the ower ends of the key stems to prevent a depression of any of the key stems and thus lock the printing keys against actuation. It will be observed from an ins ection of Fig. 3 that at this time the aralle su )porting links 3S are substantie y vertiea y disposed or are dead cent-ered so that pressure exerted by any o the key stems on t ie locking plate presses the locking plate a ainst the read centered links by a direct ownward movement so that no movement of the locking plate can take place.

The locking plate is moved intol and out of locking position b the following means: A rearwardly exten 'ng link 41 is pivoted at its forward end to the locking plate on a shouldered pivot screw 42. The rear end of the link is pivoted by a shouldered pivot screw 43 to a crank arm 44 fixed to an upright shaft 45 supported in bearings 46 secured to the left-hand side plate 1 by screws 47. The upper end of the shaft has a collar 48 fixed thereto by a. set screw 49, the collar beine* supported upon the upper bearing 46 and thus supporting the upri ht shaft 45 1n place. A crank arm 50 is ormed as a part of the collar and extends forwardly therefrom and is slotted at its forward end as indicated at 51 for the reception of a pin 52 which rojects from a rod or shaft 53 mounted) in bearings 54 for longitudinal and turningI movement. The bearings 54 project from brackets -55 secured by screws 56 to the forward fixed carriage rail 4. A coiled spring 57- surrounds the rod 53 and' is secured at one end in an opening in a sleeve 58 connected by a set screw 59'with the rod. The opposite end of the coiled spring is secured 1n an opening in one of the bearings 54.

where its right-hand end bears a ainst the right-hand side plate 1 of the rame and limits the movement of the rod in this direc- This spring exerts a pressure to nor mally maintain the rod 53 toward the right tion. The s ring also exerts a force to turn the rod 53 1n its bearin to the position shown in Fi l and 2 fi' urposes which will hereina ter more cleary appear. A stop 60 is secured about midway of the shaft or rod 53 by pins 6l which ass throu h sleeves formed on the stop an through t 1e shaft to lock the stop on the shaft. The stop 60 projects rearwardly from the shaft 53 for cooperation with line lock and margin stops carried by the carriage as shown in Fig. 1. l

detachable stoprod 62 is secured by screws 63 to the carriage and is located beneath tl1e platen. The forward face of this stop rod 1s providedl with indices 64 which correspond to the carriage scale. A line lock stop ($5, a linal line lock stop 66, a margin sto 67 and a final margin stop 68 are adjusta ly secured to the stop rod. The fastening mea-ns for securing each of the four stops 65, 66, 67 and 68 to the stop rod 62 1s the same so that the description of the fastening means for one of these stops will sulice for all of them. The stop rod 1s provided with teeth 69 on the bottom side thereof as shown in Fig. 4; and from an inspection of Fig. 7 it will be seen that a hooklike locking member 7 0 forms part of a stem 71 threaded at 72 for coperation with an 'internally threaded finger piece or cap 73 by which the locking device 70 is actuated. A coiled expansion spring 74 is received in an openmg 75 in the stop in which the stem 70 and finger piece 73 operate. The coiled spring 74 surrounds the stem 71 and bears at its upper end against the lower edge of the cap or finger piece 73 and bears at its lowerl end against the lower wall of the opening 75.- The spring thus exerts the force to maintain the lookin'y member 7U seated between the teeth 69 ofc the sto rod to lock the stop in place on the rod. ach of the stops is cut out to provide an opening to receive the stop rod so that each stop surrounds the stop rod on three' sides, leaving the fourth side of the o enin free or open to provlde a withdrawa of t e stops from the rod when the rod is removed from the machine. When the stop rod is in place in the machine the forward faces of the stops just clear the forward rail 6 of the ycarriage and a displacement of each of the stops from the rod 1s thereby prevented, although the stops may be adjusted longitudinally of the rod when the lockin mem ers or latches 70 are 'released from t e teeth 69. The line lock sto is provided with a depending portion 6 having a Het vertical face 77 on the left-hand side thereof, the right-hand side of the projection 76 being beveled as indicated at 78. The 'construction therefore is such that in the movement of the carriage from rivht to 'left the rflat face 7 7 of the/pro-A jection l6. will be brought into engagement i with the stop 60 to eiect a movement of it together With its rod 53 to the left until the pressure of the spring 57 and is eiective to l tiirn the uprightfrock shaft. ta through the crank arm 50. An oscillation ot the roch shaft 45 efects a forward movement of the link 41, thus moving the locking plate 'troni the positionshown in 2 to that indicated in Fig'. 3 Where the openings 40 in the locking plate are thrown out of register with thelower ends of the lrey stems, thus locking the key stems and the type actions against actuation. In the movement of the carri age just described the projection 76 iii-st meets a trip b (Fig. 4t) connected with a suitable alarm to Warn the operator oit the approach of the carriage to the end of a line.A

I have provided a line lool-z releasing' Imeans in order to enable the operator to Write one-or more characters to complete a' Word or insert a liyphen after the printing' keys have been locked against actuation. This line lock release comprisesI a release key 79 connected to a key stein S0 which in turn is 4pivotally connected 'to the forward end ot' ay horizontal arm of an angular lever fil pivoted to a stud which projects inwardlyr from the lett-hand side or end plate l of the frame. The upright arm ot this angular lever is connected with a pull link S2 which has its rear end pivotally connected to a depending' crank arm S3 secured to the rod o1' shaft 53. By depressing the .release key T9 a Jforward movement of the crank arm S3 is effected which is operative to turn the rod so 'that the stop GO will move doivn- Wardly and clear the projection 7G on the margin stop as shown in Fig. G, thus rcleasing the stop GO from control of the mar- `gin stop andalloiving' thek spring 57 to iestore it to nin-'nal position by movingl the stop rod-53 lon; tndiiially to its normal position. The effect ot' this movement is to restore the locking plate to its normal position shown in land 9. to release the printing keys. From an inspection of Fig. 3 it Will be observed that vthe slot lin the crank arm 50 extends at right angles to the axis of the -shattor rod `50 when the looking plate is inthe locked position so that the rod 53 at this time may be turned ivithoii't atiectingr the arm 50 and Without'being' affected by it. After the line lock has been released v and` one or more characters have been Writ; ten and the margin stop G5 passes .to the `left ot.' the stop 60, pressure on the release key') having been released, the stop G() will again be moved into the path o'tl the projecti'oii 7G. lf, however, the carriage be moved toi the riglit at this time the beveled tace 78, will depress the stop (SG against the pressiirc'of its spring 57 so that the stop 'GO at i this time oiiers no obstruction oi'' the movenient of the carriage, to the right. The final line lock stop 5G has a depending contact portion Si longer than the projection T6. The length of lthis projection is such that 73` the swinging' movement of the stop GO is insiitlicient to clear it o't the projection S41 so that the line lock release key is ineifective to clear the iinal stop 6G. This stop coperates with thc stop G0 in the same manner as the line lock stop G5, except that the stop 6G cannot pass beyond `the stop GO. rlhe margin stop 67 has a. depending projection f. which cooperates With the .stop GO in substantially the saine manner as the line so lool: stop (35 does, except that when the niargin stop contacts with the stop (30 the right hand end of the rod 53 abiits the right-hand end plate l of the frame as shown in Fig'. 2, and a longitudinal movement of the rod 53 to the right at this time is therefore prevented and the carriage will be arrested in its movement to the right. A depression ot the release key, however.y is effective to tiirii the stop G0 out ot the path ot the projection 85 on the margin stop to enable the operator to move the carriage farther to the right to Write within the margin it desired. ln the return movement of the carriage a beveled tace 86 on the marginl stop contacts with the stop (30 and turns it lto one side to enable the carriage to travel freely past it. The final margin stopS is'provided with a depending' projection S7 Which isv longer than the projection 85 and cannot be cleared by the 1.00 stop GO when the release key 7 is depressed. From an inspection of Figs. l and 2 it ivill be seen. that the margin and line loch l stop are carried by the carriage and are situated beneath the platen Where ordinarily.105.v

they would be inaccessible to the operator. I'loivever, 'by providing' a platen `trame which can be swung' back from the full io the dotted line positions shown in Fig'. l the platen and the platen frame-together with all the other parts carried by the latter are Aremoved Jfrom the position where they constitute an obstruction, and access is readily given to the margin and line loclcstops in order that they may be quickly set` from the i front of the machine. After the stops have been set the platen frame is turned down to the normal position shown in full lines where. the margin stops are out ot' View and occupy a. space Where they cannot be easily deranged or broken. ln short, the swinging of the platen frame covers and uncovers `the margin and'line lock stops so that in one case the stops are not accessible .to the operator and in the other case they are. ii It will be seen that by incliiiing' the supporting links when the locking' plate in the normal position and having' the linksl .moveto the dead centered position when the tios, key actuated abled to utilize the weight of the locking plate itself to move it tov locking position so that but little power is required to actuate the line leek mechanism from the travelingv (,farriap'e.
