TYPEWRITING-MACHINE.

To aZZ whom t may concern.'

Be it known that I, JOHN WALDHEIM, a

citizen of the United States, residing in Elizabeth, in the county of Union and Sutate of New Jersey, have invented certain new and useful Improvements in Typewritlng'- Machines, of which the following is a specification. This invention relates'to an improvement in typewriting machines, and more espe- 'cially toI key-set tabulating mechanism.

The purpose of the invention is to enable tabulating mechanism for a typewriter carriage to be rapidly and accurately set, so as to determine subsequently tabulated positions for the carriage. The carriage is provided with settable stops, Ione for each letter-space, and when the carriage is selectively positioned and a lever operatedin one direction, a stop corresponding tothat positionfof the carriage is s'et. Al number of stops can be set in thisl way 'to determine a plurality of major columns or Zones at which the typewriter carriage must thereafter stop. The decimal-tabulating mechanism is, 'usedto coperate WQiththese carriage-carried stops `to position the carriage according to the pre-arranged lan;

The set stops can be unset y operating the same leverI at the keyboard but in the opposite direction from setting any selected stop, after the carriage has been positioned to bring the stop into register with the setting and unsetting plate. 'The shiftinglever for the stop-setting m ans is-normally held in intermediate neutral positionbymeans of a pair of spring-actuated counterbalanced arms.

Other features and advantages will helgeinafter appear.

In the accompanying drawings, Figure 1 is a vertical section, taken from front to rear, with parts omitted to simplify the showing, and illustrating the stop-setting and clearing lever in a neutral position. Fig. 2is a detail section, taken from front to rear,J of the stop-setting mechanism, .showing the stop-carrying bar as raised in 4 the act of setting oneof the stops.

, Fig. 5 is ali-vertical, detail section of a modified form of stop-carrying bar, which can be operated from the carriage instead of from the keyboard, as inthe case of the form shown in the remaining gures.

Numeral keys 1 and alphabet keys 2 depress key levers 3, torrock bell-cranks 4 so as to swing type-bars 5 up rearwardly against the front side of a platen 6 mounted to rotate on a carriage 7. The carriage 7 .has the usual step-by-step movements when the numeral keys and character keys 1 and 2 are actuated, under the control of an escapement mechanism indicated .in general at 8. .'This escapement mechanism -includes a rack bar 9 supported by the carriage 7 by means of arms 10. "The rack bar 9 normally .engages a pinion 11 connected by a one-way pawl-and-ratchet mechanism noto shown)l to an escapement wheel 12. `The wheel 12 is controlled by a pair of iiXed and loose dogs 13 and ,14, which are operated by a universal frame 15. The universal frame 15 is connected to a universal bar 16, which llies in the path of heels 17 carried by the type-bars 5. This esca ement' mechanism is the usual Underwoo typewriter escapement mechanism, and acts at the striking of the character keys to control the advancing step-by-step movements of the carriage 7 as it is drawn by the usual spring Vbarrel ,18.

In addition to the step-by-step movements, sthe carriage 7 may have major or .jump movements under the control of a tabulating mechanism. This tabulating mechanism includes a plurality of decimaltabulating keys 19, one for each decimal column within the capacity of a Zone or major column.. The tabulating keys 19,

.when depressed, rock key levers 2O to raise at theirrear ends plungers 21. The plungers 21', when thrust individually in this` way, come into the path of the set stops of a series 22 carried by the carriage 7.

The typewriter carriage 7 is released by the tabulating keys 19 as they are depressed, so as to-permit the spring barrel 18 to draw the carriageuntl the next one of the stops .22, which happens to be set, is obstructed in its movement by the particular plunger 21 lprojected.` Todo this, each of the plungers v 21 is provided with a ledge or shoulder 23 formed by a notch cut out of the associated plunger. These shoulders .underlie an arm lil@ 24, universal to all of the plungers 21 and forming part of a lever 25. When any of the tabulating keys 19 is depressed to move its lplunger 21 to an obstructing position, the lever 25 is rocked so as to draw down on a link 26, and thus rock a lever 27 pivoted intermediate its ends. The lever 27 carries at its forward end a roller 28 under-O lying the rack 9 and acting to raise the rack 9 out of mesh with the pinion 11. In this way, the carriage is released to permit it to jump forward until obstructed by an engagement of the next carriage-carried stop capacity of the carriage 7, and only such stops as are to be used are set at any particular time. The stops 22 extend vertically through slots 30 provided in the rail 29, and have projections 31 and 32 extending over and under the bar 29, so as to limit the upand-down movement of the stops 22 relative to the bar 29. The stops 22 have two positions, one raised and inactive, and `the other depressed and active. The stops are locked in these positions by spring-pressed 'balls 33.

The rail 29 is mounted on a swinging frame 34, which is pivoted on theV carriage 7, and may move from an intermediateposition to either a depressed position, shown in Fig. 3, or a raised position, shown in Fig. 2. In the raisedposition shown in Fig. 2,

the particular stop 22, corresponding to thel position of the carriage 7, will be set.y In

the depressedposition illustrated in Fig. 3,

a previously-set stop, corresponding to the position of the carriage, will be unset'. The setting and unsetting of the stops 22 are accomplished by a fixed plate 35, which is provided with an upper arm 36 extending above the row of stops 22, and a lower arm 37 eX- tending below the row of stops 22. The plate 35 is locatedl just lto the left (Fig. 4) of the series of plunger-s 21, or, in other words, just to the left. of the plunger which determines the decimal-point position of the carriage for any particular zone.

The-shifting of the frame 34 and thus of the rail 29, is controlled, in the form shown.

in Figs. 1 to 4, by a hand-lever 38 located at the front of the machine adjacent the bank of character keys 1 and 2. Normally, 'the hand-lever 38 occupies the neutral posiagainst movement, being tion shown in full lines in Fig. 1, but it may Abe shifted alternatively to either the setting position or the clearing position, indicated in dotted lines in Fig. 1. When shifted to the setting position, the hand-lever 38 draws on a link 39 to rock a bell-crank 40. The bell-crank 40 draws on a link 41, so as to rock downwardly and forwardly a shifter 42. This shifter 42 is provided with a cam slot 43 having several cam surfaces, one set 75 46a serving to normally lock the stop-bar 22 for this purpose formed as arcs struck om the pivot 42a of the yshifter 42, and therefore being dwells. Another pair of these cam surfaces, indi- `cated particularly at 44, act, when the shifter 42 is swung downwardly and forwardly in this manner, to thrust upwardly and forwardly on a rod 45 extending through the cam slot 43 and located on the swinging frame 34. This swings the rail 29 `upwardly to force th'e particular stop 22, located in register' with the setting plate 35, against the upper arm v3G thereof. As this arm is stationary, it will cause the particular stop in question to be depressedbelow its fellows.

The shifter 42 is also providedwith a pair of opposed cam surfaces 46 bordering the slot 46, which, when the lever 38 is forced to the position marked clear in Fig. 1, swings the frame 34 downwardly (Fig. 3), so as to bring'a previously-set stop, which corresponds to the position of the carriage, against the lower arm 37' of the plate 35. This will cause-the stop to move up relatively to the rail 29, and, when the rail 29 is returned to a normal position, it will be in an unset position. The lever 38 and the parts shifted thereby are held in a normally intermediate position by means of counteracting spring-actuated mechanism. This includes a block 47 secured to the link 3-9 and engaged on opposite sides by a pair of arms 48 and 49 pivoted at 50 land 51. The inward movement of the arms 48 and 49 toward each other is limited by a stop 52. The arms 48 and 49 are held against the stop 52 by means of springs 53 and 54.

The operation of thisY form of the device 115 so far described will be readily understood when taken in connection with the abovedescription. or the purpose of illustration, the series of stops 22 may all beassumed to be unset. The carriage 7 may then be po'- 120 sitioned by the usual scale and pointer to the particular location desired for the first major column or zone and for the decimalpoint column in that zone. This will bring the stop 22 for that zonein register with the 125 setting and unsetting plate 35. The lever 38 may be shifted to `the set position illustrated in dotted lines in Fig. 1, whereby the frame 34 will be rocked forwardly and upwardly, so as to raise the rail 29. and carry 130 the particular stop 22, corresponding to the zone or major column selected, up against the overhanging arm 36'. The further movement of the stop 22 is obstructed while the rail 2-9 continues its movement, thus" causing the stop to be displaced downwardly relatively to the rail .29 to a set position. The handdever 38 is then shifted to' an intermediate neutral position by the spring 54, and the cariiage 7 advanced to the decimal point in -thenext major column or zone desired. Then the lever 38 is again shifted to the set position to adjust the selected stop 22 to a set position. The operation is repeated for eachzone or major column within the range or capacity of the carriage 7. When the carriagelcarried stops 22 have been -set according yto the desired plan, the parti-cular work' for-'which same were set can be done. l y

For each line of writing, the carriage starts at the right and one of the decimaltabulating keys 19 is depressed according to what particular decimal column in the qirst Zone is desired. The depression of this decimal-tabulating key releases the carriage,

'j so that it starts to jump forward untilthe associated plunger 21, which has been projected, obstructsthe movement of the first set stop 22 on the carriage 7 At 'the rise of the tabulating key, the carriage, as isusual, steps forward a letter space, or nearly a letter-space, until it is arrested at the desired point by the loose dog 14. It is to allow for this stepforward nthat the setting plate 35 is set to the left ofthe decimal plunger 21. This is repeated for each zone or major column, selecting, if desired, different decimal columns in each zone by operating the proper tabulating key 19.

For a change in the setting of the stops 22 for some other kind of work, .the carriage 7 is positioned, by the assistance of the decimal key 'of the tabulator keys 19, to bring each set stop individually into register with the plate.'35, and the` lever 38 is shifted to the clear7 positionillustrated in l, so as to rock the stop-carryingbar 29 downwardly,thus forcing the set stop to an unset position. A

A modified form of device is shown in Fig. 5, in which the stop-carrying rail 29 is more directly operated from a'point adjacent the carriage 7. In this case, the stopcarrying rail 29 is mounted on a, frame 55,

which, 1n turn, ispivotally mounted at 56 on the carriage 7. This frame is provided with an arm 57 extendin upwardly to a projecting position above t e carriage 7 and located at one side thereof The arm 57 is normally held in a neutral position by means of a pair of springs 58 extending on opposite sides of pins. 60 and 61, located, respectively;

` on the arm 57 and the carria e 7.

The arm 57 is provided with a handle 62,

stop rail 29 can be shifted either up or down to set or unset the stops 22.c A plate 63, similar to the plate 35, is provided with an overhanging arm 64 and an underlying arm 65, so as to set or unset the stops 22 laccordin to the manner in which the rail 29 is shifted. The operation of this form is the same in a general way as the .form illustrated in the other figures, and the stops 202 are set in a similar manner, the only difference being that the operating handle is carried by the typewriter carriage, and, therefore, the rail 29 is more directlyoperated.
