TABULATING ATTACHIMENT FOR TYPE-WRITING MACHINES.

Patented June 30, 1908.

Application filed August 7, 1903. Serial No. 168,621.

Be it known that I, HUBERT K. HENRY, a citizen of the United States of America, add a resident of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in 'lahulating Attachments for Type-W riting i\lach ines, of which the following is a specification.

The main objects of my invention are to provide simplified and improved tabulating mechanism for typewritmg machines; to provide such construction for said tabulatsame may be IPitdll? applied to machines already in use, witi little modification to the parts of such machines; to provide means whereby the car- 'i'iage of a typewriter may be shifted for printing columns of matter in any one of a plurality of positions by a single. movement of a key by the operator; and to provide simplified means for stopping the carriage at positions corresponding to units, tens, hundreds, etc., for any setting of the column 1 accomplish these objects by the device shown in the accompanying drawings, in which:

Figure. 1 is a transverse vertical section of a typewriting machine fitted with a tabulating device constructed according to my invention, some of the parts of the machine being omitted for the sake of clearness; Fig. 2 is a rear elevation of the same. Fig. 3 is a top plan of the tabulating device and such parts of the machine-as coact or are connected directly therewith, the other parts of the. machine being removed. Fig. 4 is an enlarged top plan of the spacing mechanism and the adjacent parts. of the tabulating de- Fig, 5-is a rear elevation of the parts shown. in Fig. Fig. 6 is a perspective view of the clip which serves as a stop for the carriage in connection with the tabulating device. p

In theconstruction shown the frame 2 of the typewriter has slidably mounted thereon the usual carriage 20' which carries the platen roll Extending along the rear side ;oi the carriage 20 and secured thereto in the usualmanner is a feed-rack 19, having a series of rack-teeth along its lower edge. A

pinion 18 meshes with the teeth on the rack 19 and is rigidly secured to theshaft 17 1 I l I 19 a ratchet-wheel 16. The teeth on the ratclwt-wheel 16 are so )laoed that a rotation of said ratchet-wheel through one tooth space corresponds to the advance of the carriage through one type space. The carriage 20 is urged along the frame 'by the usual spiral spring 30 and ta )e 31, shown in Fig. 2. A dog 15 is pivotally mounted on the bar 32 of the frame 2 and is normally urged into engagement with the ratchet wheel 16 by means of a spring 33. The advanee ol' the carriage 20 is ell'eeted by moving the dog 15 out ofcengagcment with the ratchet xheel 16. A lever 1.; is pivotall mounted on the bar 32 on the same axis with the dog 15 and has a rearwardly extending arm 13. A lug 14 on the lower side of the lever 13 engages the dog 15 and moves same out of engagement with the ratchetwlicel 16 when the lever 13 is moved forward.

The keys 1 which control the operation of the tabulatiug device described, are located in front of the lower part of the frame 2, in convenient position to be pressed by the thumbs of the operator. The keys 1 are'carried by the rods 3 which are slidably mounted in the. bars 2 and 2 of t frame; and each has rigidly secured thereto a flat bar 4, whichbars extend upwardly and rearwardly as shown in Fig. 1. The rods 3, together with their connections are normally urged forward by means of spiral springs 6. The rear ends 5 of the bars 4 are brought into vertical alinement and each is constructed to engage a downwardly projecting arm 8; the latter being in the path of the side portions 7 of the ends of the bars. The arm 8 is pivotally mounted in the frame that is, it swings on a horizontally disposed arbor 9. A vertically disposed lever 10 extends along the arm 8 and is pivotally mounted at 11 on the arbor 9. It will be seen that the lever 10 and the arm 8 together have a limited rotar movement around the arbor 9, while the ever 10 is also laterally rotatable around the fulcrum 11. The upper arm of the lever 10 is forked to form two horizontally disposed parts 10' and 10. The lower arm 21 of the lever 10 is provided with a plurality of shoulders 22, (2?, 22, etc.) each respectively arranged to engage one of the ends 5 ofthe bars 4, when such bar is pushed rearwardlv as will be 8 is adapted to engage the shoulders 34 on the lever 16. and thereby limit the movement of said arm about its fulcrum '1-1. The end portions '7" are so located as to ermit each bar 4 to be moved lengthto be posed tothe part 13 of" the lever 13 throu out the entire ra e of movement of the ever 10 about the fu crum 11.

Rigidly secured along the rear side of the carriage, 20 and movab e with said carriage,-

is a horizontally disposed bar 25. The bar 125 is graduated to correspond with the scale of the machine and has a series of notches extending along its entire length and adapted for securing a removable stop 26 to the bar 25.as indicated in the drawing. The arm 8 and the lever 10 are urged into, their normal spring 28 which is coiled around the arbor 9 and bea s on an adjacent part of the -frame 2. The end 27 of the part 10 of the lever 10 is located immediate y-in the rear of the bar 25 and sufficientlyl far from the bar 25 to ermit' free passage of the stop 26 when the ever 10 is in its normal position, as shown in The'operation of the device shown is as follows Suppose that the operator desires to write a column of numbers and assume, for

example, that it is desired to print the Idecimal point at the part of the 'sheetlcorresponding to number 57 of the scale. Then the stop 26 would be placed u on the bar 25-at the notch 57 as shown in- 'g 3. If now the first of the keys 1 (that-is, the one indicated by the letter a in Fig. 3) is pressed inwardly by the operator, the',bar 4 which corresponds to the key a, will be pushed rearwardly a ains't the-action of the spring 6, the end 5 othe bar 4* will move across the'path of the lever 10, and the shoulder 7, bearing upon the arm 8, will cause the lever 10 to rotate about the fulcrum 9 in the direction of the the part 10 to push the lever 13 forward and release the dog 15 from engagement with the ratchet-wheel 16, thus freeing the carriage 20'. The spring 30 will now advance the car- 1 riage until-the step 26 strikesthe end 27 of;

the lever 10. The carriage now tends to cause' the lever 10' to rotate on its pivot 11, against the ull' bf the spring 23, until such rotation is c ecked throu h the engagement ofthe bar 4 with the shou der 22 which cor responds to such bar. -Whenthe pressure is now released-from the key a, the spring 6 seaoto' return said key, together with the bar 4, to their normal position and the sprin s 23 and 28will sim taneously return -the ever 10 to its normal position. of the extension'12 upon the lever 13 is thus also released, the spring 33 will now return 'thedog 15 into engagement with the ratchetwheel-16, and hold the carriage in readiness for receiving an impression. The stop 26 projects rearwardly from the bar 25-sufii ciently to remain in contact with the end 27 'of the lever 10' and hold the carriageuntil waiter Since the pressure the dog 15 has been returned to a position of.

engagement with the ratchet-wheel 16., It will be noticed that thelever '10 forms a yieldin detent, adapted tolimit the move-' ment 0 the. carriage and at the same time, through the action of the spring 23, absorb the'momentum of the carriage and avoid a shock due to the sudden stopping of'same. Further the ends 5 of the bar 4 o rm stops for limiting the movement of the lever 10 on ria e.

a will be understood that the fulcrum 11 and the lever lOare so located with respect its pivot 11, after same is struck by'the car-. position, shown in Fig. 1, by means of a is pressed, t e carriage 20 will be stopped in such position that the paper on the platen roll'willreceive an impression at a point corresponding to the location of the stop 26 on the bar 25. The remaining shoulders 22', 22, etc. on the lever 10 are so arranged that each will permit a correspondingly less move ment of. the lever 10 ,and wil cause the stopping of the carriage at 1, 2, etc., type spaces in front of the space corresponding to the position of the stop 26.

t will now be understood that, if the stop 26 is placed at the oint corresponding to the type space in whic it is desired to print the decimal point of the column of figures, then by presslng the key a, the carriage will be sto ped in suitable position for printing such decimal point. Similarly by pressing the key I) the carriage will be stopped in suitable position for printing figures 1n the units col umn; and in like manner the keys 0, (Z, c, and f correspond respectively to the figures in the columns of 10s, 100s, 1000s and 10,000s. Since upon the release of the tabulating key the lever 10 is released from engagement with the sto 26 and the carriage 1s free to continue a ong the frame, any number of such stops may beplaced along the bar25 for the urpose of successively stopping the carriage in positions for printing a series of rows -of columns.

It will be seen that numerous details of the construction shown may be altered without (lleplarting from the spirit of my invention.
