Be it known that I, BELA GEREBEN, a sub- 1 the main frame andS is a coiled spring the ject of the King of Austria-I-Iungary, residing ends of which are secured respectivelyto-the at Budapest, in the Kingdom of Austrial spindle l and the adjacent bracket 2: 011 Hungary, have invented certain new and l' the spindle 1 is secured a?si1iglc'piece graduuseful Improvements in 'labulators for l i Type-'Writers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a tabulator device for typewriters.

The essential feature of my invention consists in providing a rotating graduated stop cooperating with the tabular stops, means being provided for turning and fixing the said rotating stop in its different positions and means being provided to actuate the cardial steps 5.' The distance from each step to the next corresponds with the space of the letters of the typewriter, and with the carriage-feeding movements. On thespind'le 1 a sleeve'6 is loosely mounted to turn freely relatively to said spindle. From the said sleeve a lever 7extends (lownwardly the end of which is bent outwardly at a right angle. A substantiallyhorizontal thumb 8 projects backward from sleeve 6 and rests on the well ward projecting arm'lO of the sleeve 6 bears the brake plate 11 covered with leather or the like and acting against the flat brake-bar 12 mounted on the carriage.

Further means may be provided to allow the tabular stops to yield in the direction permitting to turn the rotating stop when adjacent to one of said tabular stops.

My invention aims also to improve the brake acting on the carriage, when this latter is released on the working of the tabulator.

The scope of my invention will be more fully described and claimed hereinafter.

In the accompanying drawing, which illus trates an embodiment of my invention applied on the machine-type known under the name Underwood, Figure 1 is a rear elevation of the upper part of the machine provided with the tabulator. For the sake of clearness several details of the typewriter are omitted. Fig. 2 is aside elevation of the tabulator device with the adjacent parts of the typewriter. Fig. 3 shows the cross section of the oscillating stop rod with the tabular stop when yielding on the action of the rotating graduated stop. Fig. 4 is the front View of the tabular knob with the dial or tabular scale. Fig. 5'shows diagrammatically the improved wedge shaped brake bar in plan view. Fig. 6 shows a modified form of the rotating graduated stop. Fig. 7 shows the preferred form of finger piece for setting the wedge shaped so that the acting face of said bar is slightly divergent to thepathofthe carriage, the braking effect increasiiigE thus toward the end of the travel of the carriage.

B and supporting-the toothed taliul'ar'stop rod 14, the. ends of which are pivoted in said bracketslB. l A spring fastenedwith its ends respectively to the tabular stop rod 14 and to the left bracket 13 acts to return the .rod 14 in its normal position shown in Fig. 2 when it was turned in the'position Fig. 3. On the brackets 13 abutments 16 may be. formed (see also Fig. 3) fixing the normal position (Fig. 2) of the stop bar. I

The spindle 1 supports near its left end a bevel mien 17 fixed thereto and meshing with the pinion 18 supported by a vertical shaft 19 journaled in

bearings

20,21. secured to the main frame A. Tothe lower end of the shaft 19 is fixed the bevel pinion 22 meshing with a pinion 23. The bevel pinion 23 is secured by means of its hub 24, on a horizontal spindle 27 to rotate together with said spindle but to allow a longitudinal shifting of the spindle in the hub of the pinion. The spindle 27 is journaled in the bearings 25 and denomination stops. Y

A is the main frame of the machine and B is the carriage. Both are oi the well known construction.

bracket 26 to the bearing 2]. and. the latter secured to the main frame A. The frontend ated stop 4 provided with a plurality of raknown carriage releasing lever fi. f Aii up'-.

As shown in Fig. 5, the bar 12 is slightly 7 13, 13 are brackets secured to the carriage 28, the former attached by means-oi the of the spindle 27 is provided with a knob 29 having a recess with roughened surface adapted to receive the thumb of the operator when turning the knob. Y

On the main frame A is secured a dial 31 and on the part of the spindle 27 between the frame and the knob a pointer 32.

A rin'g'33 forming a shoulder is fixed to the spindle 27 and a spring 34 is located between the bearing 25 and the shoulder 33 secured respectively to said bearing and shoulder. When the knob 29 is turned or pushed the spring 34 is stretched or compressed and will return after the knob is. released this latter together with the spindle 27 in the initial position.

The spindle 27 is fitted with a disk toothed on its periphery, the teeth corresponding withthe scale of the dial 31. On a support secured to the main frame a pin 36 extending toward the toothed disk 35 is arranged to enter the corresponding recess betweenthe teeth of the disk 35 when this latter is approached to the pin 36 by pushing the knob 29.

The device operates in the following manner: When a number of four figures for instance shouldbe written, theknob 29 is' turned until the pointer reaches number 1000 on the dial. The knob is then pressed in, whereby the position of the knob and the spindle 27 is secured from rotation by the pin 36 entering the recess of the disk 35 being in front of the pin 36. The pin 36 and the recesses of the disk 35 may be wedge shaped or tapered to facilitate the operation. By turning the knob 29, the spindle 27 is rotated and the movement of this spindle is transmitted by means of-the bevel pinions 23, 22, the shaft 19 and the

pinions

18, 17 to the spindle 1, turning thus the graduated stop 4 with an angle corresponding to five steps on the stop 4, because 1,000 corresponds to the fifth degree of the scale of the dial. By ushing the knob inwardly, the spindle is shifted longitudinally in the hub of the pinion 23 without altering the position of this latter fixed by the pin 36 engaging the disk 35.

The end of the spindle 27 is disposed in front of the bent end ofthe arm 7 so that on shifting the spindle 27, the lever 7 and the sleeve 6 is slightly turned-on the spindle 1..

Thereby on the one hand the thumb 8 depresses the carriage releasing lever 9 and is pressing on the other hand by means of the arm 10 the brake plate 11 against the brake bar 12. The carriage thus released will jump until the stop 37 mounted adjustably on the tabular stop rod 14 willabut against the fifth step 5 of thegraduated stop 4 brought by having turned, the knob 29 into the path of the tabular stops 37, 38. The movementof the carriage is lgpverned by the action of the brake 11, 12 w ch increases toward the and of the travel of the carriage owing to the wedge shape of the bar 12. The knob 29 is then released by the operator, whereupon the parts are brought by means of the

springs

3 and 34 in their original position. The pressure exerted on the carriage release lever 9 ceasing, the escapement of the carriage, which is designated by C is put in action and stops the carriage in the position determined by the stop 37 and by the fifth step of the rotary stop 4.

If a number of five figures should be written, the rotary stop willbe moved so far, that the sixth step is turned into the path of the tabular stop 37 of the carriage and if a number of three figures must be written in the column of numbers, the rotary stop 4 will'be turned so that the fourth step may extend into the path of thestop 37, and so on.

It will be understood that the operator must maintain pressure upon the finger-piece 30 until the carriage is arrested by the stops, and that the tooth 36 is intended merely to lock the shaft 27 against rotation.

When the carriage is stopped by the mutual action of the stops 4 and 38, the operator releases. the knob 29, and the stop 4 rotates to normal position. immediately turned again without first Writing anything, the rotary stop 4 can easily be turned by said knob, to any desired point, in spite of the fact that stop 38 is in front of the stop 4 (see Fig. 2). '1 he stop 4 abutting against the stop 38 tilts the stop and the pivoted rod 14- (Fig. 3) until 4 can pass by 38-. In other words, by the rotation of the stop 4, the column stop 38 can be turned out of the way, effecting a rotation of the bar upon which the stop 38 is mounted. The carriage may then be released and then arrested by the engagement of the next column stop with the selected stepped shoulder on stop 4.

It will be seen, that the

stops

37, 38 limit the travel of the carriage, but do not hinder the rotationof the graduated stop 4.

It will be understood, that the details of myinvention may be varied in different ways without departing from the scope of my invention. Thus the helicoidal graduated stop 4 need not always be provided with steps but can be formed as a continuous helical surface, as shown in Fig. 6 and the tabu lar stops arran ed 'on the rod 14 may be fitted with similarly formed oblique faces. Instead of the knob shown in Fig. 4 the-knob shown in Fig. 7 may be used, which is provided with a wing 39- for turning the knob by means of the index, while the thumb resting If now the knob 29 is on the knob 40 seryes for pushing in this lat?
