Application filed January, 3, 1920. Serial No. 349,192.

To all wham'i t may concern lie it known that I, ()SC.\R oonwzi in. citizen of the l nited States. and'rcsident of Babylon, in the county of Siifiolk and State tion. 7

My invention relates to typewriting machines and more particularly to'tabnlating mechanism therefor.

Heretofore in certain characters ofcolumn selectingmechanisms, the constructions were such that any desired column could be selected at will, but where the operator desiredmcrely to use the tabulator' to jump the carriageto successive columns, or from one columntothe nextthroughout successive fields, it was necessary to operate the selecting keys successively, say, first, the No. l selectin key for the first'column, then the No. 2 selecting key for the next column, and soon. This entailed on the operator remembering what selecting key was last 0 crated, or an inspection of the work in eac instance to determine the position of the next column to be selected, and then a selection and operation of the corresponding tabulator key. This resulted in confusing! the o )er'ator, diverting the operators attention from other aspects of the work in hand,

and the loss of't me that might advantageously be used in the production of more work, and sometimes in mistakes which caused furtherconfusion and delay The main purpose of the present invention, generally stated. is to provide simple.

and effective means by which these difficultics maybe overcome anda single one of the selecting keys preferably key Number 1'. may be used continuously to jump the carriage successively from one column to the next, without. howcvcr. dcstroying the availability of the selecting incclianisii'i to bc used as such.

To the above and othcr ends which will licreinaftcr appear my invention consists in the features of construction. ariiingcincnts of parts and. combinations of devices to be set. forth in the, following specification and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters designate corresponding parts in the various views.

Fig. 7 IS a view corresponding to Fig. 6

but showing another modified form of stop construction. .I have shown my invention in the present instanceembodied in a X0. 11) Remington machine which includes column selecting mechanism ofthe character disclosed in the patents to G. A.- Seib, Nos. 1132,286 and 1.273.545, dated respectively Men. 16, 1015 and July 23, 1918.

While the present invention is susceptible of embodiment in No. 10 Remington machines with but few and inexpensive changes it should be understood that the invention may be incorporated in other styles of typewriting and like machines.

I have shown in the drawings only so much of. the No. 10 Remington machine as may be necessary to arrive at an understanding of my invention in its inclusion therein.

The frame of the machine includes a top plate 1 on which a carriage 2 is mounted to travel from side to side of the machine, the carriage carrying the usual cylindrical platen 3. Rearwardly projecting arms 4 are sccured to the carriage near the ends thereo' #1011 and support ii column stop bar 5 formed The tabu ator ume 7 is secured by sci s- 8 to the toff late of the machine and sup- 20ig'nated as a ports pivoted selecting levers 9 each of which terminates at its upper end in a forwardly extending finger 10 which co-acts only wit 7 its particular pivoted column selecting stop 11. It follows therefore that each column selecting key is operative to actuate the companion lever 9, and to prOJect forwardl "the particular s'elect n sto 11 with whlcl; saidleverco-acts. The se ectlng stops 1 are arranged in different horizontal lanes and each is adapted to swing forwar y on a pivot 11" in a-fixed path or invariable plane, which difie'rs from t planes of movement of 'all of the otherjstops 11.

1 1.5 This is efi'ective'to bring'the projected stop 1 V 11 -into cooperative relation only with the ';particular stop projection on the particular counter stopzor column etc with which it is -to co-act. achof the co umn stopsis deswhole by the reference numeral These column stops areconstructed d ihfis t Thus each s p 1 12. somewhat like the" column etc the up lic-ation of Elbert S.) filed cc. 26, 11918. formed with a central 1" urcated toreceive and strad e the column stop bar.- Two sheet metal side plates 14 are riveted at 15- on opposite sides of the body portion 1330f the stop. Each sheet metal late 14 is bifurcated to -straddle;the Stop Ear, but the inner parallel walls 11' of the plates extend inwardly farther, than. the body portion 13 of the stop, so that they may be received inthe interdental s aces between the teeth 6 on the stop bar. ach sto is-provicled with a finger piece 16 and wit a suitabledetent to retain the stop against -aiccidental displacement from the bar. .In the present instance this detent is in the mfnature of a ball 17 which is received in a '1 socket or aperture 18 formed inth'e .body portion 13 of the stop, either at the forward side thereof as shown in F ig. 2,.or at the rear side thereof as shown in Fig. 6. Each to ball is ressed toward the column sto bar 5 by a col ed expansions ring 19 which ears at one end against the all and at its .optpo siteend against a set screw 19" threa ed into a tapped portionof the opening18. 50 Each sprm'g.19 thus exerts a force on the ball to cause it to bear against the lower corners of the adjacent teeth 6 on the column stop bar and thus prevent an accidental displacement of the stops from the bar. The efigstops may, however, be readily ,detached from the bar and reversed thereon or adjusted to different points along the bar. It will be understood that the inner end of each recess or opening 18 which receives a '60; ball 17- is slightly contracted in order to limit inward movement ofthe ball contained therein. 7

Projecting from the body portion of each 1; stop 12 atone side thereof. is an engaging 1 5 member or arresting projection, portion or operate the select .stop with an additional step Figs. '1 to 4, inclusive, the stop projection key, which contro contact. These projections or contacts are arranged in diflerent horizontal planes, each havin a different path of movement correspon ing to the fixed plane of movement of its coacting selecting stop 11. In order that these contacts or projections on the cphunn stops may be clearly distinguished 1n the drawin I have designated them by separate re erence characters 20, 20, 20", 20,an d 20". It will be seen from the foregoing that an operation of the highest selectmg stop 11, by its associated key (not shown), results in moving said selecting stop into the path of the projection 20 on the right-hand cplumnstop, as the partsappear 1n Eig. 3, said selecting stop 11 being ineffective on all the other column stops. So it Is with cache-f the other columnselectmg stops, each bei'n cooperative only with the parumn stop with which it is supticular co posed to coact. With this arrangement 1t lflnry, should the operator desire to move successively from one column to the next, ingkeygsuccessively 1n the out. y In order toavoid the confusion which may result in. using the tabulatortp ump the carriage to successive columns in the man ner describedJ have provided each column pn'ojectron engaging member or contact 21 which pro ects in the opposite direction from the stop rojections hereinbefore described or from the opposite side of the body port1on13 of the etc member. These sto rejections orcontaci s 21 are all arrimgesin the same plane,

orin one ine all having the same path of movement. Iii the construction shown in 21 is arranged at the top of the stop, at a height corresponding to the stop pro ection 20 solthat when the column stops are detached and reversed on the stop bar 6 all of the projections 21 will be arranged so that they may coact with the uppermost selectin "stop 11.- It follows therefore, that re ate. operations of a, sin le key, say the o. 1 the ulppermost select ing stop 11,- will result in t e-carriage mov ing successively from one column field to the next'with the aid; of this single key. I I

In the construction shown in Figs. 5 and 6 it is unnecessa to detach the. column stops and reverse t em in order to bring th'e 120 alined projections into use. In this modified formof construction parts which corres end to those previously described will be esignated by the same reference characters. The column stop bar-5, as shown in Fig. 5, is pivoted at one end, as at 22, to its supporting member or section 23, which in turn 18 supported by one of the arms 4 of the carriage. A locking flange. 24 is secured to the stop bar and is provided with two no one, two, three order as hereinbeforeipointed 9 on opphsitie sides thereof. Aflocking latch 26 ispivotecl 5115 27 on the supporting member and has alocking projection 28 atoneendthereof which adapted.

'tion the additional projection-or arresting portion 21 on each of the-column stops is situated at'the' lower'cnd of the stop, i n- {stead of at the upper end thereof-as m the 1 previously described.constructron all of the projections 21" being in the same-line. By releasing the. locking-latchifi and giving the bar a hailf turn from the position shown in Fig. mall-of the stop projectionsdlflwill be bronghtto'a position corresponding to 2-5 that previously occupied by the projection 20. All of the pro ections: 21 will thereforqb positioned to; enact with theulppermost" selecting sto 11 cofitrollethhy the WXo. 1,selectingjey. Theadvantage of 301 this modified formofconstruction is that it is'unnecessary to detach thecolumn'stops .fromj the bar in'order to b'rin either one set or the other set of stop pro ections into From the foregoing descript on itijvill be seen thatench efthe key controlled stops 11 is moved in-an' nnvhriable fixed path;'

that the contacts Q theregn are so nt-ranged that eftch contact cu planes. thate'xtcnd transversely thefim'v-z rhino or in thejgen'eral direction, of the travel ofwthecarrmge; and that-the selectable stepped contacts 2(), ;2(J, 2(l!-, Around 20' on tlu-. -rcyersil ile duplex colnmn stops are arranged to move in parallel paths and in awcordnnce with the 'azran ement of the a-on'tucts on the key w'o ntrollet 'stops'll, It

will also he observed that each contact 20,

whereas the other series of contacts 21 are f'nniformly arranged on their stops in a single line and travel only in a single path.

While l have shown "five selecting sto )S 5-5 and five coacting column sto is, it will 1e lunlcrstooll that the number of such stops jolnploycd may he varied.
