Only so much of a typewriting machine is illustrated in the present case asis necessary to disclose the invention and its operation and the location of the various elements with respect to the other parts of the typewriting machine. In my co-pending application Serial N o. 243,063, tiled December 28, 1927, I disclose a. motor for returning the carriage and a key lever controlled mechanism for the motor.

In my co-pending application Serial No. 239,493, filed December 12, 1927, I disclose a power operated mechanism for effecting a line spacing movement and also a. carriage return movement. In this copending application, however, the'carriage can be returned by the power operated mechanism from any point in its travel, and the line spacing movement effected at any point in the carriage travel, exceptwhen the carriage is within a predetermined number of letter spaces from the center stop.

' My present invention provides for a key lever controlled power operated mechanism for returning the carriage from any position 1n its travel, as well as eifecting a line spac- .ing operation even when the carriage is usual construction and further description is deemed to be unnecessary. Associated with the carriage 1s the usual escapeinent mechanism which'includes the escapeinent pinion 1 adapted to engage the letter spacing feed rack 2 which is supported on the carriage B. The carriage as in most all typewriting machines is moved from right to left in its letter spacing movement through the medium of a spring motor G and the escapement mechanism above described. The feed rack 2 is supported on the main frame A by arms 3 which are pivoted as at -4 to said main frame, whereby the rack may be swung upwardly and thereby disengaged from the escapement pinion 1. A spring 5 is connected to one of the arms 3 and to the main frame A for`yieldably retaining the feed rack in engagement with the pinion.

The line spacing mechanism D includes a bell crank lverf which is pivoted at its angle on a vertical-'post 7' mounted on the carriage B. Oney arm 8 of this bell crank lever is pivotally connected as at '9 to one end of a link '10, the other end of said link being pivotallyconnected as at 11 to an arm 12 pivoted as at 13 to the carriage. pawl 14 is pivotally mounted on the link for engagement with a ratchet l5 lixed to one end of the platen C. The otherarm 16 of the bell crank lever 6 is connected to one end of a draw band 17, the other end of the band being connected to a winding drum 18 journaled on a shaft 19 mounted on the rear wall of the main frame. The band 17 is trained over a roller 20 which is located intermedi- -ate the bell crank lever 6 and the drum 18.

From the foregoing, it will be observed that whenever the drum is rotated in a clockwise direction to wind the band therearound, the bell crank lever will be first actuated to effect aline spacing movement and upon the completion of this line spacing movement the continued winding of the band on the drum will effect a carriage return movement.

The power mechanism employed for line spacing movement and for carriage return movement is constructed as follows:

yA motor H is mounted lon thebase 2l of the machine frame A and this motor drives an axially alined shaft 22 through the medium` of a friction clutch I, the details of which are fully disclosed in my co-pending a plication Serial No. 243,063 referred to a v e. Fixed to the shaft 22 is a worm 23 which' drives a worm wheel 24 fixed on a clutch .shaft 25. Loosely mounted on the shaft 25 isla driving pinion 26 which meshes with a gear 26a fixed to the drum shaft 19 so as to rotate saidl drum in a clockwise direction when the pinion -26 is connected to the shaft 25. In order to connect the pinion 26 with the shaft 25 there is provided a twoart clutch, one of the members 27 being xed to rotate with the pinion 26 and the other member 28 being mounted on the shaft 25 to rotate therewith and to also move 1ongitudinally thereof. These members 27 and28 are provided with clutch faces. The meinber 28 is provided with a peripheral groove 29 for receiving one end of a clutch lever 30 which is fulcrumed upon a horizontal stud 31 carried by a bearing lug 32 which is mounted on the base 21 of the main frame A. A spring 33 has one end connected to the upper arm of the lever and has its other end fixedly connected to the main frame of the machine. This spring functions to normally urge the clutch member 28 rearwardly into engagement with the clutch member 27. A bell crank lever 34 is pivotally connected at its angle as at 35 to the base 21 of the main frame and one arm 36 of this lever cooperates with the lower end of the clutch lever 30 to move the same against the tension of the spring 33 and thereby disconnect-the clutch members. The'other yarm 37 yof the bell crank lever is pivotally connected as at 38 to an ear 39 which extends forwardly from one end of a slide arm 40. The arm`40 is provided with an elongated and longitudinally extending slot 41 and a guide screw 42 extends through the slot 41 and is threaded into the rear wall of the machine frame, as shown in Figure 7. When the parts are in the position shown in Figure 7, the clutch is disconnected but when the slide arm is moved to the right as shown in Figure 11, the clutch is connected. In order to provide means for holding the clutch disconnected, I have provided a latch 43 which-is pivoted as at 44 to the rear wall of the machine frame. One free end 45 of the latch constitutes a stop shoulder and is adapted to normally engage a forwardly extending ear 46 fixed to the slide arm 40 and thereby retain said slide arm against movement towards the rightpand consequently retain the clutch disconnected. The latch 43 is provided with an extension 47 which is ada ted to engage the base 21 of the machine rameA and thereby limit the upward movement of the free end 45 thereof. A spring 48 has one end connected to the .latch 43 and the other end connected to the machine frame. This spring 48 functions to yieldablylretain the latch in its normalA latching position as shown in Figure 7. It will be observed that when the latch 43 is swung downwardly against the tension of the. spring 48 so as to lower the free end 45 from' engagement with the ear 46, the slideyarm 40 will be moved to the right under the influence of the spring 33 and consequently the clutch members will be 'thereby connected.

For the purpose of releasing the latch 43 and thereby connect the clutch` members, I have provided a key lever controlled mechanism therefor which may be either'power operated or manually operated. In Figures 1 and 3, I have shown a power operated key lever mechanism, whereas in Figure 2 I have shown a manually operable key lever for this purpose. Referring particularly to Figures 1 and 3, the power operated key lever mechanism includes a key lever 49 which is fulcrumed on the main frame of the machine and is adapted to trip a power actuated lever 50 to cause a star wheel 51 to contact with a power shaft 52 which isdriven from the motor H. The power lever 50 is provided with an arm 53 which is moved forwardly when the power shaft 52 is engaged by the star wheel 51, the engagement between the star.

interme "ate its ends upon a stud 62 supported on the rear wall of the machine frame, and the free end of the lever 61 is provided with a forwardly extending ear 63 which is vdisposed above and in contact with the latch 43, as shown in Fi re 7.

Thus when t e carriage return key lever 49 is depressed, the power shaft 52 will through the medium of the star wheel 51 and the power lever50 rock the crank lever 56 which is fixed to the supporting shaft 58 and thereby rock the lever 61 and cause the ear 63 thereof to move downwardly against the latch 43 to disengage the nose 45 thereof from contact with the ear 46 of the slide arm 40. This will rmit the slide arm 40 to be moved to the rig t by means of the spring 33 to effect a coupling of the clutch, as previously described. p

In the presentinvention the letter spacing feed rack 2 is elevated and thereby disengaged from the escapement pinion 1 during every operation' of the carriage return key lever 49. The lifting of this rack releases the carriage and causes said carriage to leave the starting position of the writing line under the influence of the spring motor G, and after the carriage has been moved about an inch or so the carriage return clutch is automatically connected and the carriage is then again returned to its starting position immediately subsequent to the actuation of the line spacing mechanism D. If the operator should desire to line space the paper with the car-v riage in its starting position, this is accomplished by depressing the carriage return keyJ lever which lifts the rack 2 and-causes the carriage to move away from the center stop 88 for a distance of about an inch or so.. The clutch yis then automatically connected and the line spacing .mechanism D is then actuated after which the carriage 1s returned to its initial position. Thus any number of line spacing movements may be effected by the power` mechanism when the carriage is in its starting position. The advantage of this operation is that the heavy jar of the carriage against the marginal stop is considerably reduced by increasing the distance for the carriage to travel. The depression of the carriage return key lever 49 causes the spacing rack 2 to be lifted and also latched in its disconnected position and remain in such disconnected position until the motor drive clutch I has exerted a considerable pull on the carriage return draw band 17 which force releases the latch'that is holding the carriage rack in its disconnected position. Fixed to the shaft 58 is an arm 64 having sliding contact at its free end with an ear 65 fixed to one end of a rack lifting lever l66 which is fulcrunied at 67 to the carriage B. The lever 66 is provided with an arm 68 for contact with the rack 2. Thus when the shaft 58 is oscillated upon depression of the carriage return key lever 49, the arm 64 will be moved forwardly, and this arm will in turn rock the rack lifting lever 66 and elevate said rack to disengage the same from the escapement pinion 1|.- The free end lof a lever 64a which is also fixed to the shaft 58, is provided with a radially extending tooth 69 which is adapted for engagement with a spring latch 70 pivoted as at' 71 to a bracket 72 fixed to the rear wall of the machine frame. The bracket 72 is provided with a forwardly extending lug 73 and a coil spring 74 is connected at one end to the free end of the latch 70 and at its other end to the lug 73. This spring 74 serves to yieldably retain the latch 70 in engagement with the tooth 69 of the rock arm 64a and thereby retain said rock arm in its operative position. Therefore while the latch 70 remains in engagement with the rock arm 64a the feed rack 2 is held in its upwardly adjusted position out of engagement withv the escapement pinion l. This of course permits the carriage to be moved freely under the influence of the spring motor G in a direction away from the center stop 88.

As soon as the carriage has been moved a predetermined short distance, say for a distance of approximately ten spaces or about' an inch, the latch 7 D is automatically disconnected from its engagement with the rock arm 64a and consequently the feed rack 2 is lowered into engagement with the escapement pinion 1, and power mechanism through the medium ofthe draw band 17 returns the carriage to its initial position a ainst the marginal stop. For this purpose, have provided a lever 75 which is pivoted at its lower end to the pivot screw 62 of the latch releasing lever 61. The upper end of the lever is provided with a roller 76 which engages the draw band 17. The roller 76 is located between the roller 20 and the Winding drum 18. The lever 75 is provided with a linger 77 which contacts withthe free end of the latch 70 and is adapted upon movement of the lever 7 5 in one direction to release said latch 70 from engagement with the rock arm 64a. The spring 74 serves to yieldably urge the lever 75 to the right as viewed in Figure 9 whereby the roller 76 will normally cause the band 17 to be bowed outwardly. Thus when the clutch is connected upon the depression of the carriage return key lever 49, the feed rack 2 will be elevated and held in such elevated position by the pawl 70, thereby permitting the carriage to be moved under the influence of the spring motor G for a predetermined distance such as ten spaces or the like. By this time the winding druml 18 has been brought into action and a pull exerted on the draw band 17. This initial pullstraightens the bowed portion between the roller 20 and the winding drum 18 and consequently the lever 75 is swung to the left against the tension ofthe spring 74, as viewed in Figure 9, whereupon the latch is released and the feed rack 2 is consequently lowered into cooperative engagement with the escapement pinion l. As above explained the continued rotation of the winding drum 18 will eifect first a line spacing movement and secondly a return movement of the carriage. p

It is of course desirable to disconnect the clutch members 27 and 28 as soon as the car'- riage is returned to its initial or writing position at the beginning of a line, and for this purpose the following mechanism is employed. I

At the rear of the machine there is mounted a vertical clutch disengaginglever 78 which is supported to turn about a transverse axis 79 in a bracket 80 which is supported on the main frame A for pivotal movement about a fore and aft axis 81. The Jlower end of the lever 78- is provided with a forwardly extendingl foot 82 which extends through an opening 83 in the rear wall of the main frame at a point immediately to the right of the sllde arm 40, as viewed in Figures 7, 11, l2 and 13 particularly. The marginal stop F is previded with va rearwardly extending cam 84 which is ada ted, when the carriage is being returned to its initial position, lto engage a shoe 85 xed to the upper end of the lever 78 and thereby cause said lever to rock on its transverse axis 79 to project the foot 82 there-- of forwardly to the position shown in Figure 12.

The cam 84 is provided with anadjustable set screw 86 adapted to engage a forwardly extending arm 87 carried b the shoe 85 and thereby cause the clutch isengaging lever 78 to swing on its fore and aft axis'81. In other words, the upper end of the lever 7 8-is moved towardsthe ri ht, and the lower end of said lever is moved towards the left as viewed in Fi re 7. This movement of the lever causes t e-slide arm 40 to be moved y towards the left from its Figure 11 position to the position shown in Figure 7, thereby disconnecting the clutch members 27 and 28, and permitting the latch 43 to be so as to retain the slide arm 40 against movement towards the right. Consequently the clutch is held in its disconnectedy relation until the carriage return key lever 49 is'again depressed. During said movement of the lever 78, the upper end thereof is swung to the.

right until the arm 87 contacts with the fixed lcenter stop 88 in'which position the carriage lis brought to a state of rest at the beginning y of a line.

Secured to and depending from the foot 82 of the clutch disengaging lever 78 is a Vstop pin 89 which is normally disposed in rear of a stop lever 90 which is pivoted as at 91 to the base 21 of the machine frame. This stop lever includes an arm 92 to which one end of a coil spring 93 is connected, `the other end of the spring being connected to the base moved upwardly under the influence of the spring 48 21. The lever is also provided with a rearwardly extending stop shoulder 94 adapted'` for engagement with the rear wall of the machine frame and yieldably held in such enga ement by the spring 93. When the clutc disengaging lever 78 is rocked on its transverse axis 79, the stop pin 89 is moved.

forwardly and thismovement swings the stop lever 90 on its pivot 91 against the tension of the spring 93. During the last-part of the carriage return movement Ithe lever 78 is rocked on its fore and aft axis 8l, by engagement with the marginal stop F and con- The stop pin 89 is retained in this position while the carriage is 1n its extreme position against the center stop, and also during the period the carriage is moved under the inline position shown in iluence of the spring motor G for a distance equal to the width of the shoe 85. In other words, as soon as the carriage return key lever 49 is depressed, when the carriage is in its extreme position against the center stop 88, the spacing rack 2 will be lifted from operative engagement with the escapement pinion 1 and latched in said elevatedposition, thus permitting the sprin motor G to move the carriage a distance su cient to withdraw the cam 84 from engagement with the shoe 85. Immediately thereafter the drum will begin its rotationin a clockwise directionv and wind the draw band 17 therearound. As

a result of the slack being first taken out of this band, the lever 75 is moved and the latch 70 disengaged from the lever64a thus permitting the feedv rack 2 to automaticall return to engage the escapement pinion "1. mmediately following the return lof the rack, the continued winding of the band 17 on the drum first elects a line spacing operation and after the completion of this line spacing operation the carriage is returned to its initial or stopping position. During the time the carriage is moving away from the center stop. and until the cam 84 has left the shoe 85, the clutch members 27 and 28 are held in their disconnected relation for the reason that the clutch disengaging lever 78 can not swing on its fore and aft axis 81, because of the stop lever 90 being at this time disposed in the path of movement of the stop pin 89. It is evident, however, that just as soon as the cam 84 breaks contact with the shoe 85 the clutch lever 78 will be free to swing on its transverse axis 79, thereby moving the stop pin 89 rearwardly out of the path of the stop lever 90 to permit the slide arm 40 to be moved towards the right and the clutch members 27 and 28 to connect.

From the foregoing, it will be observed that I have provided a power operated mechanism controlled b a key lever which will effeet a return of the carria've from any point in its travel; which will eect a line spacing( movement of the platen at' any position of the carriage in its travel, and which will effect a line spacing movement ofthe platenand a return movement of the carriage in any position of the carriage in its travel, upon the depression of a single control key lever.

Instead of employing .a power operated key lever, I may employ a manually operable key lever 95, as shown in Figure 2, this lever being connected to the link as will be readily understood.

It is obvious that changes may be made in the precise form and arrangement of the parts without in any way departing from. the spirit of the invention which is to be regarded as limited only by the scope of the appended claims.
