Application filed January 5, 1917. Serial No. 140,818.

To all whom it may concern:

Be it known that I, LESTER A. VVERNERY, a citizen of the United States, residing in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Typewriting-Machines, of which the followin" is a specification.

My invention relates to typewriting machines and more particularly to tabulating devices for such machines. It isherein disclosed as applied to a combined columnselecting and decimal tabulating device, forming part of an Underwood typewriting machine. In such column-selecting and decimal tabulating devices, it is advantageous to have a decimal tabulating device which will be effective even if no column-selecting key is depressed, and yet to provide con nections such that if a column-selecting key is depressed, the decimal tabulating mechanism will bring the carriage to rest by the depression of a single other key. It is also an advantage to many people to be able to set the column-selecting key and thenlater depress the decimal tabulating key. It is also desirable to have a mechanism for col- ,umn-selecting which can be easily incorporated with the standard types of machine manufactured on the large scale, thus reducing to a minimum the necessary special work in producing a s ecial machine adapted to special needs. esides this, it is advantageous to have the connections in the machine such, that if the keys are depressed in the wrong order, the operative can correct the position of the carriage by a second operation of the keys in proper order without having the attention distracted by having to push back the carriage and reposition it etc.

It is further advantageous to have the settable parts, such as the tabulating stops, either convenient to the front of the machine themselves or to have them settable by some keyboard,said latter be held 1n place when depressed until the keys being adapted to carriage substantially reaches its position to be arrested and then thecarriage may release the key practically in the act of bein brought to rest. The key itself while de pressed, bemg numbered on the front, serves as an lndlcator to indicate at what column the machlne has been set to come to rest. Other features and advantages will herelnafter appear.

In the accompanying drawings, Figure 1 1s a skeleton perspective view showing an Underwood typewriting machine haying my invention applied thereto.

F 1g. 2 1s a schematic View of my invention showing the carriage and a few cooperating parts. 7

Fig. 3 is a sectional side view of the machine seen 1n Fig. 1, the parts being in normal position.

Flg. 4 is a View similar to Fig. 3, butshowmg the position of parts the instant before the column-selecting mechanism is released to arrest the carriage at the second column.

In the usual Underwood typewriting machine, type-keys 1, depress key levers 2 to swing type-bars 3, by means of sub-levers 4, upwardly and rearwardly against the usual revoluble platen 5,'so that types 6 and 7 will print against the front side of said platen. As each type-bar approaches the platen, a heel 8 thereon strikes a universal bar 9, moving it rearwardly to vibrate the usual detent and feeding dogs 10 and 11. These dogs form part of the escapement mechanism and cooperate with the escapement wheel 12, to permit the typewriter carriage including the platen to be drawn along by the spring barrel 13, a step at a time; the escapement wheel 12, for this purpose being connected to a pinion 14, which meshes with a. rack bar 15, the latter connected to the typewriter carriage 16. The carriage runs on rails 17 and 18, in the frame of the machine.

In order to enable the carriage to be rapidly positioned at any desired point, a decimal tabulating key 19, on the front end of a key lever 20, may be depressed to raise or project a plunger 21, at the rear of the machine into the path of a carriage stop 22 on a rack bar 23. Any stop 22 which is able to be effective projects some distance below the rack bar 23, and when in that position, strikes against any fully elevated Patented July 20,1920.

plunger or counter stop 21, thus arresting the carriage. For the purpose of releasing the carriage from the escapement mechanism to bring it automatically and rapidly to the position where it may be arrested by the projected stop 21, the rack bar 15 1s adaptedto be lifted out of engagement with the pinion 14. To -thus lift it, each plunger on a smooth part 31, of the rack bar 15.

The connectionsare such that the rising of the plunger stop draws down the link 28,

. bar 15 clear of the pinion 14, with the result lifting the roll 30, and thereby lifts the rack that the spring barrel 13 will draw the carriage along until the carriage is arrested by some fully projected stop 21, when that stop intercepts the downwardly projecting stop 22 on the typewriter carriage.

In the machine herein disclosed, the stops 22 are of the key-settable type, and 'for this purpose, there'is provided at the front of the machine a stop setting key 32, which is adapted to draw down a stop setting lug 33, which overlies the settable stops 22, and is of such width and so positioned, that when the key 32 is depressed, the lug 33 will depress one and only one of the stops 22 from the normal position seen in full lines in Fig. 3 into the position seen for the farther stop in said figure. To thus draw down the setting lug 33, said lug is formed at the upper end of a link 34, extending to the bottom of the machine, where it is pix'oted to a rock arm 35, fast on a rock shaft 36. Also fast on said rock shaft is a second rock arm 37, connected by a link 38 to the lever 39, of the stop setting key 32. The connections are 'such, that the depression of the key draws down the lug 33, against the tension of its spring 40, thereby setting a stop. The relationship of parts is, such, that if the typewriter carriage is positioned according to its scale 41, at any given point, the stop 22 depressed with the carriage so positioned, is the stop which will arrest the typewriter carriage at that point if the decimal (i. (5., period) decimal-tabulating key 19 is depressed. The stops 22 may be returned from their set position to their normal position by actuating an ordinary stop resetting bar 42, provided with slanting cam slots 43 engaging pins 44 to enable the sliding of the resetting bar 42 to lift the stop 22 upwardly. Within the rack bar 23 are staggered detents 45, cooperating with detent notches 46 in their various stops. The parts so far described rack bar 49 is suitably graduated to correspond with the scale bar 41, and is provided with notches 50, at letter-space intervals on opposite sides of the bar, so that the stops 48 when inserted, straddle the bar and engage the bar into both of their legs. The rack bar 49 is fast to brackets 51, which in turn are fast to the front of the frame 52 of the typewriter carriage. The brackets 51 extend over the scale plate 41 of the typewriter, thus bringing the rack bar 49 to a point where it is convenient to set the stops, and they are far enough below the surface of said scale to enable the scale numerals to be easily read, and in addition are so positioned as to enable the ordinary margin stops to be easily accessible to the fingers of the operator.

In order to enable the column stop keys 47, to select columns for the purpose of arresting the carriage, each key is mounted on the front and lower end of a key lever 53, these keys being arranged in a substan tially horizontal line with the key faces vertical, to enable them to be easily read. The key-levers, except the central one which is substantially straight, are bent in toward the center of the machine, so that the terminal extensions 54 of said key levers which cotiperate with the stops 48 are in a single vertical line. 7

The column key levers 53, are journaled on a transverse rod 55, which is rigid with and forms part of a decimal key controlling frame 56, said frame also including the vertical links 57, and a horizontal bar 58, which normally lies just out of range of the decimal key levers 20, when said key-levers are depressed. The depression of a column-- selecting key 47 lifts the rod 55 together with the frame of which it forms a part,. thus raising the decimal key controlling rod 58 almost, but not quite, into contact with the decimal tabulating key-levers 20. To do this, each column-selecting key-lever 53 is provided with a cam 59, which the depression of the key carries against a fixed rigid horizontal rod '60, fast in the frame of the typewriting machine. A continued depression of the key causes the cam 59 to raise the key lever, and therewith the frame until a latch or hook extension 61 of the cam 59 engages the rod 60 and acts as a de- 4, but cannot go down far enough to raise tent, thus locking said key iniig depressed position, thereby holding the decimal key controlling rod 58 in its elevated position.

If any decimal tabulatin key 19 is then de- 1 pressed, it will go down far enough to operate the short universal bar and release the escapement rack bar 15,- as seen in Fig.

its plunger 21 into the. path of any depressed rack' stop 22. In other words, the decimal tabulating key will release the car riage and allow the carriage to be drawn along, but it is unable to arrest the carriage.

Means are provided, however, whereby the decimal tabulating key can descend and raise its counter stop 21, to arrest the car- .riage. For this purpose, the column stops 48, at the front of the machine, are each provided with a trip or cam lug 62, the lug on each stop being at a different height from the lug on any other stop, so that the lugs may have a selective action. .As the typewriter carriage travels along, when released as above described, one of the lugs 62 will lie in the path of a cam extension 63, on the terminal extension 54, of the depressed column-selecting key 47, with the result that when said lug strikes said cam, it will cam the terminal extension 54 rearwardly, thus freeing the key 47 from the rod 60 and allowing-the frame 57 to drop carrying with it the decimal key control'bar 58. This takes place about. two letterspaces before the stop 22 comes to the partly elevated plunger (see Fig. 2 in which only the set decimal column-stops are shown),

" and allows the depressed decimal key 19 which has released the carriage to go down fartherrunder the pressure of the operatives finger, thus raising the counter stop 21 at the rear end thereof into the path of the stop 22, thereby arresting the carriage at the desired point.

The rising of the decimal tabulating key 19, under the influence of its spring 64, when it is released, allows the rack bar 15 to mesh with the pinion 14, thus putting the carriage of the typewriter again under the control of the escapement wheel 12.

In order to make the terminal extensions of the column-selecting keys 47 coiiperate with the proper lugs 62, the cams .63 are normally somewhat .out of alinement with.

with a light flat spring 67 which bears against the rod 60. The frame 57 may be held in its downward normal position by means of a light spring 68, which serves to tiake up any looseness and thus prevents ratt ing.

In order to keep the terminal extensions 54 of the column-selecting key levers 53, out of the wayof catching on the clothing of the operative or on papers, etc., saidextensions rise behind the rack bar 49 and the stops 48 are so positioned that the lugs 62 that cooperate therewith are also placed on the rear side of the rack bar.

Variations may be resorted to within the scope of the invention, and portions of the lmprovements may be used without others.-
