WRITING-MACHIN E Specification of Letters Patent.

Patented Aug. 17, 1909.

To all whom it may concern:

lc it known that l, Eowino B. Hass, a

citizen of the United States of America, residing in the borough ot' Brooklyn, city and citate ot New York, have invented certain new and useful improvements in lWriting-iiiachiiies,ot which the following'is a specitioation.

This in i'cntion comprises an organization wherein are employed stops adapted to act either as margin stops or as tabular stops according vto their adjustment. Coperating with them is another stop which may be located upon the niaiirfianie of the machine when the combined tabular and marginal stops are carried upon the carriage or upon the carriage when the combined mai-0in or tabular stops are carried upon the traine. its usual, the margin stop' has cooperating with it line-lock devices.

In the machine disclosed in this application, the line-lock devices are thrown into operation whenever the carriage is arrested either for tabulation or for margin. vThe combined stops are, in the construction sliownherein, mounted to be turned about a center oi motion. li'hen turned to one position their projection is such that they serve as margin stops and when turned to another.

'position their projection is such that they serve as tabular stops.` In addition to these general iicaturcs there may be provided one such combined margin and tabular stop for each letter space ot' the machine and associated with them lor the `guidance of the operator is a scale bar which may also serve as the locking device by which the stops are held in their normal position or in the positions to which they are adjusted. Each coinbiued margin and tabular stop is adjusted by hand, the adjustment consisting in its partial rotation merely- :'idjustuicnt of the stops*longitudinally o'l thc carriage not. being-` required. Ol" course special adjustable margin stop;-A ot suitable character (-niany styles ot' which are wcll known) may be einployed, and thc stops above referred to be used as tabular stops only. They are lixed with=rctercucc to their corresponding letterspaces and their number may be whatever is desired. either one for each letter-space, o1' any less iiiinibcr--prefcralily equally spaced.

They are independently operated directly by the hand ot the operator and when set or adjusted'so remain until returned to nornial inactive position by the hand of the operator.

-So far as l am aware, it is new to provide a combined stop for both iiiarggjin and tabular use and a cooperating or center stop. It is also novel so far' as l ain aware to provide a seriesl oit stops that may be or are capable of use only as tabulator stops there being one such stop for each 'of la. series of line spaces: and by making such stops serve also as n-iargin stops, the utmost, range of adjustinent of printed niatter upon the sheetis feasible.

axis ot shaft 7. A. coiled spring 71 applied to one of these arms tends by its reaction to hold the sha'it't T against an adjustable stop T2 mounted in the right hand side. plate oi the inain traine.

lihen one of the adjustable stops is engaged by the carriage stop, the action that occurs is analogous to that which happens when the pivoted plate 2f) is struck by one oi' the stops illustrated in Fig. 1,-that is to say, the verti-ally disposed arms 51 rook slightly carryingl shaft 7 toward the lett hand side olt the machine until arrested by an :nljusiahle stop Til mounted in the lett hand side plate ot the niain itralne. Arm 5i attached to sha't't 7 at its lett hand end has at its bottom a horizontal crank projection 'It to which is attached a downwardly eX- teuding link 75 connected at its lower end to the short horizontally disposed end 76 ot' a bell crank lever the downwardly eX- tending arm 7T ot' which has attached to it a torwardly extending` link TS that is conneeted with one ot the rocker arms 37 so that the line-lock plate 4() is carried under the jn'ojections 41 on the under edges of the printing` levers whenever the cooperating stop 5t contacts with any one ot the car riaee, stops.

Ot course, the arms 5l. are pivotally connected with the shatt. The construction that is preferred as to this detail is that indicated in Figs. 11 and i12 in which the upper ends ot the arms 51 are bitnrcated as at 51, 51,the pivotal connection beingl alorded by screw pivot bolt 512 seen in Fig. 8 but omitted in Figs. 1l and 12 for clearness of illustration of the parts shown in those figures.

In the constructimi shown in Fips. 9 and l() there is a link 57 running' directly from the extension 56 ot' the rocking frame 52 to the tabnlator key ttt) and a link 59 extending` upwardly from that key to the rocking;V arm 58. 'l`he operation, however, is the same as th: t already described in respect.- to the disenagementY ot the rack trom the escapement pinion.

lln the wnstruetion shown in Figs. 7 and H. the link 57 is threaded at its lower end and passes through an aperture in a lateral plate58 on the side ot the arm AdjustingrV nuts are applied to the threaded end ot the link above and below this plate.

in the construction shown in Figs. 8 and t), the link 59- has a threaded end which passes upwardly throupjl'i an aperture in the plate or Bange 58 and has applied to its upper end suitable nuts; but in the construction shown in Figs. 9 and 1() there is also a nu`t or collar 59 applied to the thrviaded end ot the link below the plate 5S in order to maintain in normal elevated position the rocking?r arm 5S. lt desired. and as shown in Fig. 10, the normal upper position ot arm 58 may be determined by an adjustable ec centric stop 79 mounted in the end of an arm projecting inwardly from the side plate of the frame.

In the construction shown in Fig. 7, provision is made as usual for shifting the carriage. lVhen, however, the carriage is elevated, roller G8. mounted on the arm 5S, prevents the teeth ot the rack from bottoming in the grooves between the teeth of the escape wheel, and the adjustment of parts is preferably such that the relation of the rock teeth'to the teeth ot the escape pinion shall be the saine whether the carriage is in normal or in elevated position.

Above the keyboard and in line above the tabulator key t3() is a horizontally disposed key or push pin St) connected iat its inner end vwith a lever S1 pivoted intermediate its ends and carrying' at its lower free end a roller S2 adapted to bear upon and depress the tabulator key (it). Referring to Fig. 14, by ray of illustration, two margin stops are shownffsone, set at- O, the other at 80; and intermediate them, set at 10, is a tabular stop to be used for paragraphing. By Operating the paragraphing key 80, the tabular key may be depressed to such extent as not to disengage the rack trom the escapement pinion but su'l'liciently to bring the tabulator stop set at into position to be engaged by the center stop 54. By using the ordinary space lever, the carriage may be run step by step (so long as the finger ot the ope lator is held on the paragraph key) until arrested by the tabulator stop at 10, that being the position selected tor commencing the para- `graph. Vtthen the cooperating or center stop is moved with the carriage and the adjustable combined stops are mounted on the main frame, the scale as indicated in Fig. 13 should read from right to lett'.

As shown in Fig. 8, the escape wheel 83 is connected to turn in one direction with the pinion (33 and the 4pinion is free to revolve in the other direction without movement of the escapement wheel. This is an operation lcommon in typewritine machines. ln the present instance, however, the pinion G?) is locked to escape wheel` in one direction of movement by pivoted spring controlled dogs SLL having teeth 85 that are drawn into the spaces between the teeth of the pinion "the teeth S5 being;` rounded or beveled upon one tace and nat upon the other. This construetion is believed to be more positive in action and moresubstantial in construction than the devices that have heretofore been used tor this purpose.

While there has been described a series of stops one tor each letter space,vor one for each olE a series ot consecutive letter spaces, it is. otl course, obvious that there might be a stop t'or every other or alternate letter space; or one tor every third letter space;

and that these stops may be mounted in lined relation to their corresponding letter spaces. Such an arrangement would afford a suitable range fortabular Work and also for margin arrest of the carriage. In the special. torni of the invention shown in the drawings, the rotatable stops may each readily be mounted upon the shatt 7 so as to rotate thereon but be prevented from moving endwise.

While rotarjr stops having each parts oi' diierent. radius or elevation one to act as a tabular stop and the other as a-margin stop are preferred on account of the simplicity of construction and facility of adjustment and are therefore dfmned mostpracticable, t-he invention is no in its broader aspects limited to rotatable es Se far as I am aware, provide a stop capabley of dilferent degrees of projection from a normal position of inaction, so as to serve in one position or extent of projection as a tabular stop and in another position or extent ot' projection as a margin stop. Thus broadly considered the invention is not limited to the special. style and mounting of stops herein disclosed. Also, so far as l am aware, l am the first to provide a plurality et stops occupying fixed positions with respect to corresponding letter spaces of the machine and capable of use as tabular stopsTy irrespective of their use as margin stops and whether or not such plurality or series ol stops contains one stop t'or each letter space., or stops corresponding with consecutive letter spaces. ilnder practical condition of working it is feasible to dispense with some o'i the tabular stops at each end of the serirsfethat is to say, with respect both to the beginning und cnil ot the line oi print.
