TYPE-WRITING MACHINE.

Application filed Marcli24, 1909. Serial No. 485,512.

To all whom it may' concern:

Be it'known that I, OSCAR WOODWARD, a

citizen of the United States, and resident of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to line lock and margin stop mechanism for such Inachines.

One object of my invention is to provide efiicient. line lock and margin stop mechanism.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In. the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure l is a vertical front to rear sectional view of one form of typewriting machine embodying my invention. Fig. 2 is a vertical transverse sectional view showing a portion of the line lock and margin stop mechanism.

Fig. 4.- is a detail front elevation with parts in section of a portion of the line lock and alarm mechanism, the view showing the disposition of the parts just before the bell hammer is released-to sound the alarm. Fig. 5 is a like view of the same showing the disposition of. the parts when the line lock mechanism is actuated. Fig. 6 is an enlarged detail fragmentary bottom view of the line locking bar and some of its associated parts. Fig. 7 is a detail side view showing a key lever, the line locking bar and some of its actuating devices, the line locking bar being shown in the locking position. Fig. 8 is a detail perspective View of the stop on the frame of the machine by which the line locking mechanism is actuated. Fig. 9 is an enlarged detail end ele-' vation with parts in section and showing the final line lock stop and the cooperating line lock stop on the frame. Fig. 10 is an enlarged detail end View partly in section but showing the joint between the bell crank of character as that shown in the application of Arthur 1V. Smith, Serial No. 260,441, filed May 15th, 1905, the carriage construction and escapement mechanism shown hereinbeing somewhat similar to structures disclosed respectively in my prior applications Serial Nos. 362,7 34 and 4L15,378,filed respectively March 16th, 1907 and Feb. 11th, 1908.

The frame 1 of the machine supports fixed guide rails 2 oppositely grooved to receive anti-friction balls or rollers 3 which are also received in oppositely grooved faces of guide rails 1 which form part ofa carriage truck 5. End plates 6 are carried by the carriage and have parallel links 7 pivoted thereto at 8. The forward ends of the parallel links are pivoted at 9 to the end plates of a platen frame 10. The end plates of the platen frame have bearing openings therein which Patented June 14, 1910.

receive a platen shaft 11 which constitutes a carriage truck 5. These brackets are united by and constitute pivotal supports for a feed rack 15 which cooperates with a feed pinion 16 operatively connected through clutch mechanism contained in a housing 17 with an escapement wheel 18. Feed dogs 19 and 20 are carried by a dog rocker 21 and cooperate with the escapement wheel 18. The dog rocker is secured to a rock vided with forwardly extending arms '23 that support a universal bar 24 that extends transversely of the machine beneath the printing key levers 25 to be actuated there? by. The key levers are pivoted upon a pivot rod 26 secured at its ends in an auxiliary frame 27 detachably secured to the main frame of the machine. The forward ends of the key levers are usual finger keys 28. A link 29 is connected at one end to a key lever and at its opposite end to the forwardly extending arm of a bell crank lever 30 pivoted at 31 to a hanger 32. The upwardly extending arm of each bell crank is connected to alink 33 which in turn is connected at its rear end to a driver 34 pivoted at 35 to a hanger 56. Each driver is pivoted at 37 to'a type oar proper shaft 22 pro- 38. The forward end of each type bar is pivoted at 39 to a guide link d0 pivoted at ii to a segn'ient 42. The various type bars are segmentally arranged and the type hearing ends thereof normally rest against an ink pad A depression of a key lever causes the types to follow a path such as that indicated by the dotted lines in Fig. l and strike against the front face of the platen. Each actuation of a type carrier causes the universal bar to be depressed, thereby effecting a feed movement of thecarriage which is-propelled across the top plate of the machine by a spring drum 44: connected by a band or ligament 415 with the carriage. The carriage truck has brackets 46 secured thereto by screws 4:7, which brackets support a stop rod or bar a8 which is dove-tailed in cross section. This stop bar supports a margin stop 49 and a line lock stop 50 each of which is adjustable along the stop bar and may be secured in its adjusted position by a. itable spring-pressed locking device 51 whi h is adapted to engage teeth 52 on the stop bar. The construction of the line lock stops and its supporting bar form the subject-matter of a Patent to George F. Ballou, No. $03,434:, dated Nov/10th, 1908. The line lock stop 50 is provided with a bell trip 52-3 pivoted to the line lock stop at 54 and limited in its pivotal movement by a stop pin received in an. opening or cutout 56 in the bell trip and cooperative with an arm 57 on the bell trip to limit its downward movement. The bell. trip has a vertical face on the left-hand end thereof and an inclined or beveled face 59 on the right-hand side thereof. A bell hammer 60 is pivoted on a pivot screw 61 to a bracket plate 62 and has an upwardly extending trip 63 which extends into the path of the bell trip 53 on the line lock stop. A stop pin '64 pro jects into the path of the arm of the bell hammer to limit the bell hammer in its movement toward the bell and prevent it from resting thereon. A coiled contractile spring 65 is connected at one end to an car 66 of the bracket 62 and at its opposite end.

to the bell hammer. As the carriage moves from right to left the vertical. face 58 of the bell trip on the margin stop will contact with the trip arm 63 as shown in Fig. 4 and when the carriage moves beyond this position toward the left the arm 63 will be released and the spring will cause the bell hammer to be vibrated against a bell 67 secured by a screw 68 to the bracket 62, thus causing the alarm to be sounded. As the carriage moves to the right the inclined face 59 of the bell trip 53 will contact with the arm 63 which will turn the bell trip on its pivot to clear the arm 63 without sounding the alarm or obstructing the free move ment of the carriage to the right.

The bracket 62 is provided with an ear 69 in addition to the ear 66 hereinbe ore referred to and these cars are perforated to receive a rock shaft 70 that has a longitudinal as well as a rocking movement in its bearings. The rock shaft carries an upwardly extending stop 71 which extends through an opening 72 in the top plate 73 of the machine and the movement of the stop 71 in the direction of the travel of the carriage is limited by the end walls H and T5 of said opening. From an inspection of Fig. 8 it will be seen that the stop 71 is provided with a hub 76 which surrounds the rock shaft and is fixed thereto by a pin 77. A bifurcated depending lug 78 is formed as a part of the hub 76. A member 79 is received at its rear end in the space between the bifurcated arm 78 'and is rigidly secured thereto by a rivet 80. The forwardly extending arm or member 79 is provided with a contact face 81 and with a flattenedlocking face 82 adjacent to the contact face 81 for purposes which will hereinafter more clairly appear. \Vhile the members 79 and 71 are shown as separate parts rigidly connected together it should be understood that these parts may, if desired, be cast or otherwise formed in one piece. The rock shaft 70 is cut out at, 83 to receive forked fingers 8-} at the upper end of an upwardly extending arm of an angular lever 83 pivoted at 86 to the bracket plate 62. The horizontally disposed arm of the bell crank lever conncctcd to the upper end of :1 depending link 87. the lower end of said link being connected at 86 to a lever 89 of the first order pivoted on a shouldered nut 90 (see Fig. which .cooperates with a screw 91 that passes through an opening in the frame ofthe machine. The forward end of the lever 89 is pivoted at. 92 to a depending link 93 pivoted at 941 to an arm 95. The pivotal connection between ihe arm 5 and the link as best shown in Fig. 6. is etl'ectcd by a slip joint comprising a retaining piece 91- slotted to receive the stem of a headed screw \Vhen the screw is loosened and the member 94 is moved to the right a disconnection of the link 93 from its pivot 9% may be effected. When, however, the parts are in the positions shown in Fig. 6 the member 94' bears against the outer face of the link 93 and retains it on its pivot 94. The arm 95 is pivoted at 96 to a bracket 97 riveted at 97 to a cross-bar 98 secured by screws 95) to the frame of the machine and extending from side to side thereof. There are two of the arms 95 one pivoted near each side of the machine but only one of said arms is directly connected with the lever 69. A locking bar 100 is connected to and supported by the pivoted arms 95. This locking bar extends transversely beneath the key levers and is adapted to lock them against printing movement when the locking bar is in the opera-' tive position, as will hereinafter more clearly appear. Rearwardly extending arms 101 project from the locking bar and carry weights 102 at the rear ends thereof. The relation of the parts is such that when the locking bar is in the normal position shown in Fig. 1 the-printing key levers arefree to be depressed. When, however, the locking bar ismoved to the operative position shown in Fig. 7 it is brought beneath depending projections 104 on the printing key levers to prevent a depression of them suflicient to actuate the printing instrumentalities. From an inspection of Fig. 7. it will be seen that when the locking bar is moved to the operative position it will be brought into a position where the pressure exerted thereon by the key levers is on adead center against the pivots 96 of the pivoted arms 95. The lever 89 has a depending portion 105 connected to one end of a contractile spring 106, the oppositeend of said spring being connected to a pin 107 which projects inwardly from the frame of the machine. The counterweights 102 and the spring 106 restore the locking bar and the parts connected therewith to normal position.

From the foregoing description it will be understood that as the carriage moves from right to left and the depending engaging projection 108 on the line lock stop engages and moves the cooperative stop 71 the rock shaft 70 will bemoved longitudinally with the carriage toward the left, thus rocking the bell crank 85 to effect a movement of the locking bar 100 to the locking position, as

. shown in F ig. 7. The parts are limited in this movement by the stop 71 contacting with the end wall 74 of the slot 72.

The righthand end of the shaft has a collar 109 secured thereto by a pin 110. A crank arm 111 projects from the "collar and is connected at its free end to a depending link 112. The lower end of the link 112 is connected to the rear end of a lever 113 arranged beside the lever 89 and pivoted on a shouldered nut 114 secured in place by the screw 91. The lever 113 is a lever of the first order and is provided with a release key 115 at the forward end thereof, the key being arranged'in the keyboard of the machine. A contractile spring 106 is connected to the lever 113 in the same manner that the spring 106 is connected to its companion lever 89 and is also connected to the inwardly projecting pin 107. It will be understood that a depression of the release key 115 is effective to rock the lever 113 to effect a turning movement of the rock shaft. The joint between the rock shaft and the bell crank shown in Fig. 10 affords a rocking movement of the shaft independently of the bell crankand the parts eontrolled, thereby. This turning movement of the rock shaft is effective to move the stop 71 out of the path of the depending projection 108 on the line lock stop 50 so as to free the stop 71 from the cooperation with the line lock stop 50 and thus release the line lock mechanism to enable one or more characters to be written after the line lock mechanism has been actuated to lock the machine'against operation. The stop 71 has a beveled face 110 and the depending projection 108 is also beveled on its right-hand side at 117 so that when the line lock stop on the carriage has passed to the left of the stop 71 the carriage may be returned to the right without being obstructed in this movement by the stop 71. and the cooperating line lock stop on the carriage. During the movement of the carriage to the right the two beveled contact faces will come into cooperation toetl'ect a turning movement of the stop 71 around the axis of the rock shaft and out of the path of the cooperating line lock stop on the carriage.

The margin stop 19 hereinbefore referred to is adapted to engage the stop 71 in the movement of the carriage to the right and thus limit it in such movement. It will be understood that during-the movement of the carriage to the right the margin stop 4%) effects no movement of the stop 71 since this last mentioned stop is normally in engagement with the end wall 75 of the slot so that the top plate resists the impact of the margin stop 19 against the stop 71. A depression of the release key 115 is effective to move the stop 71 out of the path of the margin stop as well as out of the path of the line lock stop 50 so that the writing may be effected within the margin.

In addition'to the line lock and margin stops I have also provided final line lock and margin stops on the carriage. The final margin stop 118 (Fig. 3) has a hub secured by pins 120 to a cross rod 121 which extends between the end plates of the carriage truck. The final-stop is split at 122 and is tapped transversely through the split portion to re ceive a screw 123, the inner projecting end of which constitutes the stop proper and is adapted to contact with an abutment 124 formed on the top plate 73 of the machine. Near the right-hand end of the bar 121 is a final line lock step 125, which is similar in construction to the final margin stop 178. The contact screw 126 of the final line lock stop is adapted to contact with the contact face 81, hereinbefore referred to, 71 and to effect a longitudinal movement of the shaft 70 in order to actuate the line lock mechanism. From an inspection of Fig. 9

it will be seen that the final line lock stop,

125 has a fiat locking face 127 adapted to match the locking face 82 on the stop 71, the said lockingfaces constituting controlling means for purposes which will hereinafter appear. When the stop 125 and the mechanism can be released.

contact face 81 are brou ht into (:06 eration the effect of this engagement of the flat locking faces 82 and 12? is to prevent a rocking movement being given to the shaft at this time. It will thereforebe understood that when the locking faces 127 and S2 come into operation and the line lock mechanism has been actuated to lock the machine out of operation, that the line lock mechanism cannot at. this time be released by the release key; and that it isnecessary to move the carriage to the right before the line lock This is in order to prevent a release of the line lock mechanism by the release key after the final stop has been brought into operation and no further movement of the carriage can take place. If the line lock mechanism were released at this time it would merely enable the characters to be printed one on top of the other since the carriage can receive no further line feed movement. It will be understood that if the inner end of the screw 126 is projected sutlicient-ly far to the left of the final line lock stop 125 as to contact with the bearing face 81 of the stop 71 without enabling the locking faces 127 and 82 to come imo cooperation, then the means for automatically locking the releasing mechanism out of operation cannot be rendered effective. If, however, the screw 126 be withdrawn sufficiently far in its tapped opening to enable the locking face 127 on the final line lock stop to engage the locking face 82. then the release key is automatically rendered ineffective to release the line lock mechanism when the final stop is brought into cooperation with the stop 71.
