My invention relates to typewriti'ng machines and more particularly to means whereby tabulating operations may be automatically effected as the writing proceeds, and without the exercise of any care .or

judgment on the part o1"V the operator, and

without the actuation of special tabulating To the above and other ends whichiwill hereinafter appear,rmy invention conslsts `in the features of construction, arrangements of parts and combinations of devices to be set forth in the following specification and particularly pointed out in the ap,- pended claims.

rails 6 on the carriage bar v5. End bars or projecting brackets 8 extend forwardly from the slide bar 5 at the ends thereof and support a platen shaft 9 on which a cylindrical platen l0 is mounted. The carriage is 60 propelled by the usual spring drum 1l connected to the carriage by a strap or band'12, which latter is connected at one end to the drum and at its opposite end to a depending pin 13 on the carriage. The carriage is thus 65 mounted for movement across the top lplate from-side to side of the machine and is funder control of the usual stepby-step letter feed or escapement mechanism. In the present instance this escapement mechanism com- ,prises arms 14 pivoted to the carriage at 15 and connected at their rear endsv to a feed rack 16. This feed rack meshes with a feed pinion 17 fixed to the forward end of a shaft 18 mounted to turn in a bearing supported 75 anlsln contained within a drum 21. `Feed

dogs

22 and 23 are carried by a dog rocker 24 controlled 4in the usual .manner by the finger keys; the dogseoperating with the 'escapement wheel to afford a step-by-step,

movement ofthe carriage during the printing operations. A carriage scale 25 is mounted inthe usual manner adj acenttothe platen.

,The parts thus far described are or may be of the usual construction employed in the Monarch machine. the present instance to provide the feedrack 16 with a scale on the rear side thereof, the scale comprising numerical indices 26 spaced apart to correspond-to the spacing However, I prefer in on the carriage scaleA for purposes which will hereinafter. more clearly appear.

The upper edge of the feed rack is pref erably provided with recesses or indentures 27 eaeharranged opposite a space 28 between two adjacent teeth 29 on the feed rack. 100

I have provided a series of diseugaging or closing devices each represented as a whole by the reference'numeral 30. These devices as illustrated in FigsQl, 2, 3, 4 and 5 are each made of a strip of Wire bent on itself to form aA finger piece or projection 31, an engaging member 32 on one end, and a sec, ond engaging member '33,at the other end.` l The engaging member adapted to be seated in a recess 27 in the upper edge of 119 30 therein.

the feed rack, whereas, the lower engaging member -33 is adapted to be received in a space 28 between two adjacent teeth of the feed rack, which'space is diametrically op- 5 posite the depression 27 in which theV upper end of the disengaging device is received. There is sufficient resiliency between the tw`o engaging members or

arms

32 and 33 to cause them to spring slightly toward each other and then preyent the disengaging device from being accidentally displaced rearwardly from the feed rack. Each of the devices 30, however, may, be detached fom the rack and adjusted along it to different setv positions.

10 scale. The disengaging devices in the present instance are such that each of them is adapted to close a single space between two adjacent teeth 29 of the feed rack, and the closing in the present instance is effected by the member 33, being received in one of the spaces 28 on the rack and substantially tilling said space as indicated in the drawings. Inthis manner the space is closed against the admission ofthe teeth ofthe feed pinion The effect of this construction is to temporarily bring about a disengagement between the feed rack and pinion during the letter-space feed of the carriage, and to af# ford a skipping movement of the carriage ,until the disengaging device passes to a point where it is no longer effective to maintain a disengagement between the rack and pinion'. Then the feed rack drops down and rengages the pinion after a predetermined 40 extent of skipping movement of the carriage has taken place. This will be clearly understood from a comparison of Figs. 3, 4 and 5. Fig. 3 illustrates the parts as they appear at the instant'when an engaging device 30 is brought into coperation with the feed pinion. Thus, it will be seen that as the carriage and feed rack move in the direction of the arrow under a step-by-step feed movement of the escapement mechanism, thepart 33 of the engaging device 30 will be brought into contact with the tooth a on the feed pinion 17. Atv the next actuation of a finger key the feedpinion 17 will be rotated'in the' direction -of' the arrow from the position shown in Fig. 3 to that indicated in Fig. V4. "-'g'Ihis movementis effective to raise the rack ,against the weight thereof and the usual spring (not shown) employed to depress it, thereby disengaging the rack from the teeth O of the feed pinion. The carriage spring is jthen effective to move the carriage'and rack in the direction of the arrow unt1l` the engaging device 30 has passed over the tooth b of the feed pinion, and thefeed rack may then be Edepressed to` effect a .rengagernent with the teeth a, b, of the feedpinion. This skipping movement of the carriage is effec-- tive to move the tooth d of the feed rack from the position shown in Fig. 4 to. that indicated in Fig. 5 and to bring the tooth e of the feed rack into engagement with the tooth b offthe feed pinionas illustrated in Fig. 5. In other words, the free movementl of the carriage effected by the disengagement described, in the present instance corresponds to two letter spaces of the carriage,

or to the distance of two teeth of the feed.

rack; although the extent of this free skipa. single space 28 as a unit, this may be multi- Y plied at will by adjusting theclosing devices adjacent to oneanother. If, for instance, it is desired to aiford a three letter-space skipping movement of the carriage, two of the disengaging devices 30 maybe employed in adjacent rack spaces 28, and so on.

In Figs. 6 and 7 I have illustrated a modified form of disengagin or closing device `preferably struck up vrom spring sheet metal and comprising a bodyportion 34, an engaging arm 35 terminating in a slight bend 36 and an'angular portion 37 formed on a second arm 38 at the lower end of the strip 34; the said arm 38l and the angular portion 37 being received in the space 28 of the feed rack and closing the same against the admission of the teeth of the feed pinion.

In .order that a clear understandlng of the use of the automatically operating tabulating mechanism may be arrived at 1t may be assumed, for example, that a work sheet or blank, in the nature of a freight or way bill, is to be filled in and that such work sheet.is ruled throughout the width thereof to divide the sheet in various vertical columns, each of which has printed headings or inscriptions. placed in the machine and an inspection of the carriage scale indicates the positions in the travel of the carriagewhere the various columns are divided. VIfx the'present instance it maybe assumed that hedistance from the last character inscihc ne column to the first character to be inscribed in the next column is a distance of twoletter spaces; and.

this distance maintains between the columns throughout the sheet. In work sheets of this character the number of characters contained in eaclrcplumn isgenerally the same,

so thatthe perator roceeds to write, say, four characters on t e machine under the first heading. After the last character in This work 'sheet I this column is written thecarriage will au- 'lao lumn may be written.

tomatically skip to bring the next column to a position Where the first letter in said colpleted the carriage will automatically skip to the next column where the first character under the heading of that column may be4 written and so on through each successive column. It will be understood that theoperator thus proceeds`in the ordinary maiiner to ll in the items in the respective colL unins and that the carriage is automatically moved from column to column without actuating Athe special tabulating key or keys, and without the exercise of any special precautionto determine-the columnar position of the sheet, this'latter being automatically takencare of as the work proceeds.

It will be seen therefore that I haveA pro-v vided simple and eftiient means for filling an tabulated reports, f reight, or way bills and the like and by which much time andA annoyance may be vsaved 4the operator. Moreover, it will vbe 'understood that the e'ect may be Aaccomplished by the' simple employmentof the disengaging devices on existing stylcs'of typewriting machines, such as the Monarch machine, without l changing vor materially changing the phys-` ical characteristics of said machines as they 'now exist. It will alsobe observed that the disengaging devices 30 may be adjusted to to increase the number of spaces desired for' various positions to operate at any point on the line of travel of the carriage and may be multiplied at any given point in orde` the-free travel of the carriage between columns. It will be seen that in each of the fol-ms shown the disengaging device constitutes means for closing certain of the spaces.

28 of theA rack against the admission therein of the carriage feed device which coper- -ates with the feed rack and which, inthe A present instance, is the feed pinion.

While I have described one form of typewriting machine embodying rmy invention, it should. be understood that various changes may bc made Without departing from-fthe spirit and scope of my invention. Thus, from certain aspects `of my invention I contemplate covering broadly the provision of moans closing the spaces between 4certain nation of a power drive After this is com-4 ment mechanism therefor includingaI feed rack; and means for closing the space betweencertain of the teeth of said rack.
