To all whom it. may concern:

Be it known that l, Riemann W. UHLIG,

a citizen of the United States, residing in Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements .in Type- ,of. which the following is a specification;

This invention relates to tabulating mechanisms forltypewriting and other machines. One objector the invention is to provide simplified and improved means for selecting the stop, (preferably the column stop) by which the carriage 1s to be arrested at the tabulating operation. To this end, the stops are constructed to engage successively the teeth of a pinion to rotate the same intermittently; and a disk is connected to said pinion and provided with a volute series of stops; key-operated selecti devices being provideclto determine by which of the volute stops, and hence by which of the column stops, the carriage is to be arrested; thus enabling the operator to move the carriage at once to position for Writing in the desired column, skipping the intervening columns. The device which arrests said set of .volute stops is preferably inthe form of a single stop, wh1ch is variably movable by the tabulating keys, .so that it may beprojected into the path of any desired volute stop by simply depressing the corresponding key. 1

Another object of the invention is to simplify the construction of the machine particularly with a view, to reducing the number of keys. Usually the tabulator keys form a set separate from the type-operating keys; and it is usually found inconvenient toarrange this extra set of keys upon the na-' chine. I have contrived to dispense with the extra set of keys, and to employ the figure keys for tabulating, that is to say, the keys on the. keyboard which are usually employed to throwthe figure types aaainst' the platen. In carryin outrthis feature of the inventiomjI provi e tabulating devices which are normally inoperable by the figure keys, so that the latter may perform" their function in the usual manner, of throwing}; the figure types against the platen, without regard to the tabulating mechanism. When,

however, it is desired to operate the tabn lating mechanism, a special. key is depressed which shifts-the tabulating devices to po vices.

sition to be actuated by said figure keys; so that for instance when the key 4 is depressed, the carriage is immediately shifted to position for writing in the fourth column on the page.

Preferably the tabulator stop devices are controlled by a set of arms, which-are shiftable into and out of positionto be operated, by the type-operating figure keys. They are preferably shifted as a set by means of a single key-bar which extends along behind the usual row or. fi e keys at the :back of the he heard but c ose to said keys, so that both t e key-bar and any figure key may be depressed by a single strokeotv the finger.

Hence when the operator wishes to write instead of tabulating, he simply depresses a figure key in the usual'manner' but when he wishes to tabulate instead of 'writing, he,

ing the carriage at the tabulating operation there is employed a universal bar directly engageable by the figure key levers and movable the same distance by all of said levers;

provision being made for preventing the universal bar from releasing the carriage 'eizcept at the tabulating operation.

Other features and advantages will-here inafter appear.

In the accompanying drawings, Figure l is a ;-perspective front view partly broken away, of sufiicient of an Underwood front strike writing machine, to illustrate the principal features of the present-improve meats. Fig. 2 1s a bottom View. of the machine.- Fig! 3 is a sectional ldngitudinal elevation taken. about centrally thereof.

Fig. i is a front elevation of the carriage stop devices and certain ofthe relasing de- Fig. 5 is a front sectiomfl view show ing more clearly the check for the stop pinion which is here illustrated in its normal position. 6 is a view similar-to Fig. .4, but illustrating the carriage as arrested by the tabulating devices. Fig 7" shows a c set of the shiftable arms, whereby the figure keys may .eperate the tabulating stop devices; these arms being shown out of line to illustrate their gradually increasing lengths or heights. Fig. 8 is an enlargeddiagram to illustrate the manner in which the -coluinn stop rotates the stop pinion. Fig. l) is a view to illustrate the cam action, whereby the key bar is enabled to shift the stopoperating arms into andout of the paths of the figure key levers.

At the keyboard otthe typewritena row of keys 11, usually placed in the rear bank, is shown, said keys mounted on levers 12 pivoted at 13 and having'wrists or projec tions 14; to engage slots formed in bell cranks 15, the latter engaging typejbars 16 to throw the figure types 17 against a platen 18; the

usual springs 19 serving to turn the parts to normal positions.

The type bars operate bar 20 to effect the. feeding of a carriage 21 upon which thev platen 18 is mounted; the carriage having a rack 22 mounted on said carriage by means of arms 23, and engaging a pinion 24, to which is connected the usual escapement wheel (not shown), Whose movements-are controlled by dogs (not shown) connected to said universal bar 20., whereby the carriage is fed step by step every time that a type bar isswung to and from the platen.

Upon the carriage is mounted a rack bar 25, into which are set, at any desired intervals, similar column stops 26, which maybe for instance ten in number, to permit the writing of ten columns on the page. These column stops project below the bar in position to engage the teeth of a pinion 27 to rotate the same intermittently as the carriage advances in letter-feeding direction or to the left at Figs. 4 and 6. To said wheel is fixed a plate 28, carrying ten stops or facets 29 having volute arrangement, the first stop being nearest the axis of revolution, the next stop farther from said axis, the next still farther, and so on, the last stop in the series being the mostremote from said axis. disk turn upon a shaft 30 journaled in the framework of the machine. There is provided a key operated stop 31, normally be-.

low all of the volute stops 2%), as at Fig. 4,

so as not to interfere with the rotation of said pinion by said column stops 26, during the ordinary letter-feeding and return movements of the carriage21; but by means presently to be described said stop 31 may be elevated to any desired extent, so as to bring it into the path of any one of the volute stops 29, thereby to arrest the stop disk 28, the pinion 27 and the column stop 26, which is at the moment in engagement with the pinion, said column stop being the" onewhich corresponds to the-volute stop 29 that is arrested by the stop 31. When the stop 31 is thrust up to its highest position,-

the usual. universal.

Said pinion and its stop it will be in position to engage the first volute stop 25) in the series, and hence to arrest the disk 28, the pinion 27, and the carriage 21, upon the engagement of the first column stop 26 with said pinion. Or it said stop is thrust up only enough to get into the path of the last volute stop 29, then all the column stops'itl except the last one in the serie'swill turn said pinion 28 idly, and when the last column stop engages-said pinion the last volute stop 29 engages the stop 31, thereby arresting the carriage in position to begin writing-in thelast column on the page. It will also be understood thatby thrusting said stop 31 up to any desired intervening point, the carriage will be ar rested by the co-action of the corresponding column stop with the pinion 28. Thus the operator may determine at which column he desires the carriagetobe arrested.

There is shown herein one means of effecting variable movements of the stop 31 for the purposes just described;'but it will be understood that said stop may be set by other means, and also that the herein described key-operated devices may be used in connection with other stops than sto 31, or

with other systems of stops, for eit er column-skipping or decimal-tabulatinp, as may be desired. Said stop 31' is in the 0 plate mounted for vertical slidin movement and rigidly connected by amem r 32 to a lower rod 33; and the latter is engaged by the rear end of an arm 34 extendin from a rock shaft 35, journaled at its en 5 in the o posite base portions 36 of the framework 0? the machine. Means will now be described whereby said figure keys are enabled to rock said shaft 35 variably for the pur pose of elevating the stop 31 to different positions, whereby the carriage may variably arrested as already set forth. 1 Fixed upon said rock shaft and extending forwardly therefrom are arms 37 at intervals agreeing with the intervals between the figure key levers 12, but normally lying to one side of said levers as at Fig. 2, so as hot to be operable thereby. Hence during the ordinary operation of the figure types, the tabulating mechanism is notfafiected. Said rock 1 shaft 35 is movable en wise in its bearings to bring all of the-ar s 37 simultaneously beneath their associated re key levers 12, so that upon depression 0 any-figure ke its lever 12 will bear down that arm 37 w ich is directly beneath the same, and hence rock the shaft 35 and liftthe stop-operating arm 34 fixed thereon. In order to secure t e dermofa best'at Fig. 7, the longest arm v $4,314 i V a 31 will be thrown up into position to' engage the first volute stop .29, so as to arrest the i carriage when the first column sto 26 is in engagement with the pinion 27L Ihe arms are progressively shorter beginning with said first arm; and if there are ten of said; arms the shortest one will be beueaththe key marked 0 at the, right hand end of the row of fi ure keys, and,. depression of said he woul cause the carriage to be ar rested m .position to begin writing m the,

tenth column on the page, since the rock shaft would be given the greatest extent of movement, and the stop 31" would be lifted only far enough tb engage the last volute stop 29 of the set, andhence all of the' first column stops would pass-idly-by the pinfihe'shi'ftingef thestop-operating arms 3? to etfectivedpositions is efiectedby a keybar 38, exten keys '11, and I upon apair-o arms 40 extending forwardly.

I mg al'ong'v the row of figure ivoted by a pair of stems 39 from aroek shaft' il parallel with the rock shaft35.- Anarm '4;2- is fixed on the rock shaft 41' and carries at its'rear end a finger 43' normally lying below a camblock or col? 1ar-44' fixed u'ponthe main rock 'shaft 35. Said cam block'l finormally"overlies said-finressionof the-key 138', shaft 41 is rocke and the 411-11142 lifted; Said' finger 43 en'ga esv a cam or inclined" surface 45 upon's'aid lock 44;, and cams the shaft 35 to' the right-together with the'arins 37 fixedithereon. This movement; occurs during the initial portion of-:the depression.

of the key-bar 38. During the final portion of said depression the fingerl43, engages a "ertical-fape or dwell portion 46 provided upon said'cam block'44, to lock or detain said rock shaft 35 inits shifted position, as at Fig.1. A stop 47 may be'provided for the arm 42. The key-bar 38 is placed very close to the keys 11, so that both the keybar and any selectedk ey may be depressed by a single downward. stroke of the finger, which mayengage both the key-bar and the key at the same time, owing to their proximity. The first portion of thestroke of the key-bar occurs before the finger strikesthe For releasing the carriage, which as usual 1s power-driven, from the control of its as l capement devices, there is provided a umversal bar 50 extending beneath all of the key levers 12 and always operable thereby, although such operation is idle, unless the stop devices have been shifted to effective positions. This universal bar 50 is provided at its ends with. arms 51,.whereby it is loosely hung upon the rock shaft 35.- From one of said arms projects hackwardly an extension ,or arm 52, the rear end of which engages andlifts a vertical bar 53 intended to reprovidedwith a lug 54 to lift latter connected by arm 57'and vertical link. 58 with a lever 59, carrying the usual roll 60 :pinion 24, to permit the advance-run of the provided with a brake barrel 61 operating in the usual manner. i

provided for returning the universal ar 50 to normal elevated position. w

Referring again to the inion 27, it will be seen that the same is loc red against backward movement by a pawl "68 pivoted to the framework at 69 and having a spring 70, whereby it is normally pressed into engage- :nent with the pinionteeth. Formed upon i said pawl is an arm 71 having a double cam arm 51 is provided with a tongue 62, which peripheral groove 63'- (Fig-2),? permitting independent rocking of the arm" 51, But causing the latter to shift withthe riage-releasing mechanism. iwhensaid rock arm 52 is brought into position to engage" accurate positioning of the stop31, and another purpose being to arrest the levers '12 before the types 17 reach the piatem-sg that When the t a ulatingthe arm '64 plays idly up through a notch 66 in the stop or ledge 65.- A spiin 'tliiis" to one slde of the vertical releasing bar 53,
