To all whom 'it may concern: Be it known that I, GEORGE W. CAMPBELL, a citizen vof the United States, residingin the borough of Manhattan, city, county, and State of New York, have invented certain new and useful-Improvements in Tabulating Devices for 'lype-llf'riters, of which the following is a specification. My invention refers to a tabulating device for typewriters having the purpose of freeing the carriage from the regular escapement mechanism .andarresting it on certain corresponding and previously determined places of each line, and my invention comprisestwo stop members, one mounted on the machine frame, and the other on the paper carriage, one oi Said stop members having a series of stops individually adjustable on their support so as to be variedin position according to the location desired for the columns, and means includ ing an oscillatory and sliding iin ger lever for shifting the stops to denominational'position so that each number may be written with its digits in proper relation to those of other numbers of the same column by merely shifting a single tabnlating lever, and the other stop member having a dog for engaging the aforesaid tabulating stops, vibrating between fixed stops and held and returned automatically to normal position to enable the carriage to be fed past the tabulating'stops by merely operatingthe tabulating lever..

The invention consists in certain combinations oi mechanism of the above-described character which Will be more particularly set forth in lthe following specific description, and will be then pointedout in the claims.

In the drawings the typewriter itself is Shown only as far as it is necessary to make clear the arrangement of the new device.

Figure 1 is a vertical section-through the device; Fig. 2 is a view of the device seen from the key board, the carriage frame being shown in longitudinal section;

and Fig. 3 is a top view of the device.

. Writers (not hown in Fig. l), engages in carriage rackbar 12 pivotally mounted within lthe carriage frame S by the pivot 15. Rack-bar v12 is held in its engaged position by spring 1.6, inserted between the rack-bar and a plate 20 screwed to carriage frame 8 (Figs. l and 3), and checked in its angular motion by pin 18 and nut 17 screwed into the rack-bar-aud guided in the slot 19 of plate 20 Underneath the rack-bar 12 is arranged the leveri21 bearing on `its lower end roller '23 and iulcrumed on stud 22, which is preferably integral with main frame part 3. The relation of lever 21 to' the rack-bar l2 is shown in two views in Figs. l. and 2. Near roller 23 is arranged the shaft 25 journaled and sliding in the main frame parts 4, 5, 6, and having near roller 23 cone 24. It will be seen that, ii shaft 25 with its cone 24 is pushed in toward roller 23, the latter will bel forced to roll up the incline of the cone and leve1'2l will be brought from its normal position, shown in Fig. 2, and marked by the dotted middleline'A into the position marked' by dotted middle line B. This will cause the upper end of lever 21 to lift rack bar 12 up and disengage its rack from pinion l0, thus freeing the actionoi its propelling mechanism from the escapement control and enabling it to run freely, or under such control as may be provided in wellknown manner, until stopped by the special or tabulating 4stops now to be described.v Sufilcient loose motion is ,provided between the parts 23, 24, so that the carriage y is not freed from the escapeinent control until the tabulating stops are properly set to arrest the carriage. The position of the cone 24 can be so varied as either t0 merely lift the rack-bar from its'pinion allowing the carriageto lrun free under control oi its 'propelling spring and the operators hand, or as to lift the rack Vso above it-in which case the operator, by varying his up against the part of the carriage frame' immediately inward 4pressureupon the finger lever can cause the upper end of lever'21 to press with greater or less iorce upon the bar 12 as the latter slides along, thus acting as a brake.

Shaft 25 is axially-held in its normal position, shown thus limits th'e axial motion ofshait 25 in that direction.

On the right end of shaft 25 (Fig. 1.), is fixed a linger lever 32 with knob 33 and with segment 36 on its upper end, which latter is provided with notches 34 (Fig. 2)

adapted to engage stop finger 35 secured to frame piece 5, when lever 32 by means of knob 33 is pushed inward. The outer end oi stop-finger 35 is eut away at its under side to allow the segment 3Q to play freely within the limits set by the stop-projections 36"-which at the extreme positions of the lever 32 engage'the outer end of linger 35.-

In bracket 40, preferably made integral with frame part l, is journaled column stop-bar 41 bypins 42 which can revolve and move axially as well in-l bracket 40. On bar 4l are removably and adjustably fastened by means of its teeth 37 the collmn stops 43 by which in writing the space between the columns is determined. On the underside of bar`41 is secured lever arm 44 in a suitable place (Figs.1, 2), the lever vend of which is pivotally connected to the upwardly bent I. rear end of shaft 25 (Fig. l) by pin 45 and gently pressed against the head 47 o shaft 25 by spring 46.

The pivot 45 engages loosely in arm 44 to allow theA center, as well as to make an angular motion around pivot 42 ,from the normal position shown in Fig. 1 to that marked by dotted line C when shaft 25 is pushed rearward by pressing knob 33. The arm 44 is of fiat spring metal to allow the shaft or rod 25 to continue its -rearwardmotion for reasons to be explained later on after it has, byshiiting the arm 44 to'or toward the dotted portion shown in Fig. 1, shifted the stop bar 43 angularly sufficiently to bring the tabulating stops into engagement as vhereafter explained. lt will be seen that bar 41 can be tilted on its pivot 42 romits normal position marked by dotted line N into that marked by dotted line D (Fig. 1). On frame part 1 (Fig. 1) is secured in a suitable place stop 50 shown in full view in Fig. 2 provided with teeth (probably twoor more in number) on its upper end adapted to engagev in recesses 51, forming a locking rack on the underside of column stop bar 41, when the latter` is tilted down as described above and keeping thus bar 41 in this position from moving axially in either direction, thus transmitting the shock oi impact of the carriage direct to the machine frame, and preventing rebound of the carriage. The form o recesses 51 is shown by a dotted line in Fig. l.

On top of carriage 8 Fig. 3 a single stop 52 is pivotally mounted in a suitable place by pivot screw 53 limited in its angular motion by stop- screws 54, 55 and pressed in its normal posit-ion shown in Fig. 3 against stop 54' by spring 56. Brackets 57 and 58 holding stop screws 54 and 55 respectively may be preferably integral with carriage frame 8.V The 6nd of stop 52 issuitably shaped as shown in Fig. 3.

The manner in which the tabulating device-is operated is as follows: Aiter the desired space between the columns has been set by inserting column stops 43 (Fig. 3) in their proper places on bar 41 the device is ready for column writing. It will be seen that the carriage 8, Fig. l, held in place by rack 12 and pinion 10 connected by shaft 11 with an escapenient of the well known kind cor'n'monly used in typewriters, will be released from pinion lOwhe'n knob 33 is pressed to the' left and cone 24 moving lever 23 as already described. At the same movement, but slightly earlier in time,

the inward movement of the shaft 25 will tilt column' bar 41 into the position shown by dotted line l) as also described before and. thus cause the nose on the right side of the several column stops 43, Fig. 1, 'to come into the path of stop 52, engaging the toothed under surface of the bar 41 at the saine time with fixed dog 50. For reason of the two successive operations above mentioned performed by the shifting motion of shaft 25, arm 44 is made of dat spring metal to allow the shaft to continue the shifting motion, las already described. During the iii-st part of this motion shaft 25'tilts bar 47 until it abufsagainst lock rack-50, described before, cone 24 being hereby so disposed on shaft 25 that it does not operate lever23 yet. During the last part oi the shifting motion of shaft 25, spring arm 44 yields enough to allow cone 24 to operate The carriage when released is movedin the well known manner in the direction of the arrow, Fig. 3, to corne to a stop as soon as stop 52 strikes one o the column stops 43 tilted in' its path. When knob 33 is released shaft 25 will return to its noi'- inal position shown in Fig. l, thereby first releasing lever '23 from its cone 24 and causing carriage rack 12 to rengage in its pinion by pressure of spring 1G and the tilting bar 4l'arid stops 43 back to their normal position shown in Fig..1. This will cause carriage 8` to stop on each line on these predetermined places when knob 33 is pressed. As the spaces between the column stop 43, Fig. 3, are equal to the distances apart the writer wishes to have the decimal points of the different numbers-in one line, the carriage will stop when knob 33 is pressed for each column on the place on which the decimal point has to come, provided the segment 36 in Fig. 2 has been set so that the decimal point notch stands opposite finger 35. Aterknob 33 is released each numeral written in the column will then be behind the decimal point. If now, for instance as shown in Fig. 2, segment 36 is turned so that notch 3 will stand opposite iinger' 35 bar 4l is moved` at the saine time by means of arm 44 to the right and stop 54 will strike column stop 43 three places-before the decimal point, so that after Areleasing knob 33 any number written in this column will have three places before -the decimal point.

The device shown in vthe drawings is provided with seven notches on segment 36 before the decimal notch showing that numbers with severi places before the decimal point, can be written, but it can be readily seen that the device may be arranged for any desired number of places before the decimal point.

In Fig. 3 it will be seen that stop 52 in striking column stop 43m-will be pressed against stop 55 and as soon as column bar 41 is tilted back into its normal position in which column stops 43 are clear o the path of stop 52, the latter will jump back by pressure of spring 5G ,l

to its stop 54, and be orithe left side of stop 43m. This enables the carriage to be fed along past the successivo tabulating stopsfuntil the desired strip is reached, by successive pressures upon lever l32, without necessitating the striking of a type or space key to carry the carriage stop past the column stops.

Having thus described my invention what l claim as new and desire to secure by Letters Patent is:
