Serial No. 689,474.

To alt 'tv/mnt t may concern.'

Bc it known that I, JOHN YVALnnmn, citizen ot' the United States, and resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in 'l`ype-l`V1-iting Machines, of which the following is a specitication.

vMy invention relates to key set tabulatimzI mechanism for typewriting machines and its general object is to provide improvedA mechanism of the character specified.

More particularly my invention relates to key set tabulating mechanism ,of the stop magazine style and has for one of its objects to provide devices for preventing the blocking or arresting of the carriage and of other parts-by reason of faulty or incomplete ejection of the stops from the magazine to the stop bar or retraction from the stop bar to the magazine.

Another object is to provide improved devices fer retracting the stops and 'clearing the stop bar through the operation of a single key which operatesto release the carriage and position the stops for retraction and also to retract the stops within the magazine after such position.

Key'set tabulating mechanism of the stop magazine style is disclosed in my prior Patent No. 971,318, granted November 1st, 1910 and also in the application of Herbert H, Steele, Serial No. 686,575, filed March 27th, 1912, and my presentl invention is an improv'ement in various 'respects on the prior constructions "aforesaid To the above and other ends my invention consists in the features of construction, combinations of devicesand arrangements of parts hereinafter described and particuvlarly pointed out in the claims.

One form ot my invention is illustrated in the accompanying drawings as embodied in a No. 3 wide carriage Monarch typewriting machine but. said invention may be adapted in whole or in part to other styles of writ.- ing machines.

ln the drawings, Figure 1 is a fragmentary side elevation, partly in section, of a Monarch typevvriting machine embodying my invention, parts of the'machine being omittedand parts broken away. Fig. 2 is a fragmentary plan view of therrear upper portion ot said machine. Fig'. 3 is a vertical sectional view, taken on planes indicated by the broken dotted line 2/ in Fig. 2 and looking in the direction of the arrows at said line. -Fig. st is a fragmentary trent elevation of the denominational stops, the mounting thereof and associate parts. Figs. and G are operating `views corresponding 1n part to Fig. 1 but showing various elements in ditlerent relationships. Figs. 7, S and 9 are fragmentsry plan views illustrating various stages of stop positioning and retracting operations. Fig. 10 is a horizontal sectional view taken on the planes indicated by the broken dotted line in Fig. 1.

As appears from Fig. 1 the main frame comprises a base 1, posts 2 and a top plate 3, the latter supporting goose-neck standartis 4 to which are secured fixed rails or grooved trackways 5 and t3, said trackways cooperating through anti-friction rollers T withthe slide or rear bar 8 of a platen carrier or carriage which further includes torwardly extending end bars 9.' Said end bars provide bearingsfor the axle 10 ot a rotary platen 11 with the front fare whereof eooperate printing instrumental itiesnot shown herein but which may be of the usual'or other suitable description. The carriage is constantly urged leftward by .a spring drum or motor 12 which is connected by 'a strap 13 with an arm 11 depending from the carriage. Pivoted to the end bars 9 are arms 15 which support a carriage iced rack 16 that is normally maintained in springpressed engagement with a feed pinion 1T mounted on a stationary bracket 1S and, as is common in the Monarch machine, opera tively connected to an escapement wheel which cooperates with escapement dogs mounted on a dog rocker pivotally supported on a bracket 20' depending from the top plate, said rocker being actuated from a universal bar which underlies the printing key levers and spacing levers lotl the machine.

The 'drawings illustrate denominational tabulating mechanism of the style common to the Monarch typewriter, said mechanism comprising a set of upright denominational stop levers 21 pivot-ally supported at Q2 1n an upright trame 23 rigidly secured to the esV rear portion of the main frame of the machine. The upper end port-ions of the levers 21 are curved forward, terminating in denominational stops proper 24, said stops being maintained a letter space distance apart scribed. Tlv, actuating devices for the stop levers 21 comprise slide bars 2i' which'bear at their rear end portions upon the lower part of theframe 23 and are adapted to push against the lower arms of the levers 21 (Fig. 1). The forward ends of the arms 2T bear slidably in a detachable supporting frame 28 and are adapted to be actuated by arms 2S) which are secured to and depend from short rock shafts 30 bearing in upright portions of the frame 2S. Fixed to the rock shaft 30 are denominational key levers 31 provided at their forward ends with keys 32. lVhen a denominational key is actuated it rocks the associate shaft 30, causing the arni 29 to slide the bar 2T rearward, swinging the associate lever 21 on the pivot 22 and projecting the stop 24 into the path of the column stop. The actuation of any one of the stop levers 21 operates carriage releasing devices. said devices comprising a universal bar or ba il 33 pivoted on the frame 23 and having an extension 33 which is pivotally connected to the lower end of an upright link 34. the upper end of said link being connected to one arm of a lever pivoted at 36 to a stationary bracket 37, the other arm of the lever being connected to a lifter 38 which, at its upper end, has horizontal portions or shoes 38a underlying the feed racklG. The construction is such that 4when the universal bail 33 is swung rearward it operates through the train of connecting devices to raise the lifter 3S and swing the feed rack 16 upward, separating' it f rom the feed pinion `17 and permitting' the carriage `to be drawn rapidly leftwa rd by the springimotor 12. The usual restoring springs are provided for restoring the releasing devices and the denominational stop levers and their actuating devices to normal position when the keys 32 are released after actuation. The lifter 38 is provided with a leftwardly extending arm 38b which is slotted at its end to embrace a pin or short shaft 39 on which is mounted a pinion 40 comprised in a retarding mechanism of the Monarch style y'liich'further includes a box-like frame 41 pivotally supported at 42 in a bracket 43 screwed to the top plate Fig. 2). Reta-rding devices proper contained in the box 41 andconnected to the pinion 4() need not be further described. TheQpinion 40 underlies a toothed rack 44 which is Xedly secured by screws 45 t-o lugs 4G projecting rearward from the carriage. When the lifter 38 is raised the arm 3S" thereof acts on the shaft 39 to swing the retarder box or container 4l on its pivot and lifts the pinion 40 into mesh with the rack 44 fixed to the arriage Thus the carriage when freed for a tabulating run is connected through the\ rack 44 and pinion 40 .with the retarding mechanism, and the tabnlating run is thereby regulated.

Projecting rearward from the slide bar S are arms 47 which provide a support for a column stop bar 1S. said bar being toothed at its front and rear faces. the notches 49 between the teeth being a letter space distance apart and being adapted to receive the column stops when projected from an over hanging stop magazine or container 50 secured to a bracket 51 which is fixed tothe upper guide rail 5. At its right-hand end the magazine is provided with a cylindrical extension or barrel 52 (Figs. 2 and 3) through which extends a stop support or rod 53 secured rigidly in place by 'a cross pin 54 passing through the closedy end `of the barrel. The lefthand end of the rod carries a spring plunger 55, the outer end of which is beveled or coned. Stored in the magazine 50 is a setor series of plate-like column stops 5G notched as indicated at 57 to it over the rod 53 by which they are supported, the top and bottom edges of each stop being beveled as shown. The column stops are strung together face to face on the rod 53 and are forced aloner said rod toward the end of the magazine by a follower 58 which is slidably mounted on the rod and is passed bya coiled spring 59 surrounding the rod and contained within the barrel 52. The right-hand end of the magazine is closed by an upright guide member (30 suitably secured in place and which is provided with vertical grooves or guide ways to accommodate slidable blocks 61 and G2. the former being the stop ejector and the latter the stop ,ret"actor. The ejector is slidable downward to force the column stops successively downward past the plunger and through a slot-way (33 on to the stop bar 4S, while the retractor which extends down below the stop bar and terminates in a head (`4- operates when lifted to push column stops when in retracting position upward through the 'slot 63 and into the magazine from which they previously had been ejected by the ciector 61.

Key controlled devices for operating he ejector and retractor comprise an angular link 65 which is pivotally connected at (V5 to the eiector G1, the lower end of said link being pivotally connected with a crank arm 67 which, as shown in Fig. 10, has a hub 68 pinned to the right-hand end of a rock shaft,v 69 bearing in stationary brackets T0 and 71. Secured tn the left-hand end e" end to a stud 7 6 on a stationary post 77,

operates to restore the parts to normal position after an ejecting operation. The retractor 62 is operated by a similar train of mechanisml comprising an angular link 78 pivotally connected at 79 'to the retractor and extending downward alongside of the link .65, the-lower end 'of said link 78 beingv pivotally connected at 80 with a crank arm 81 which, as shown in Fig. 10, has av hub port-ion 82 which is fixed to the righthand end voit a sleeve 83 surrounding and bearing on the shaft 69 and confined between the crank arms 67 and'72. The lett-hand end of the sleeve has mounted on it a down,-

wardly extending crank arm S4 which is operated by a forwardly extending push rod 85, theulatter underlying the rod 73y and 'bea-ring near-its forward end in the leftha-nd frontjpostp2, said rod 85 being pro'- Vided .withbakeyjf which is operative to i i lift the retractor -62 for stop retraeting purposes. The retracting devices are provided Witha-restoring spring 87 secured at one 38h and parts controlled thereby, the stop magazine, setting and retracting mechanism as thus far` described corresponds with the construction disclosed in the Steele applica- A tion aforesaid. l i

ln tlie'stop ejccting operation, if the key 74 be 'only part-way pressed in, the stopV will -be only partially ejected, the lower partengaging with the stop bar 4S on the carriage Aao while the niiper party still remains in the magazine. Under such conditions, if vthe carriage lie released its movement will be obstructed by the partially ejected stop and the carriage will he jammed or wedged, thus preventing' movement until the partially ejected stop can be either wholly ejected 0r else pushed back entirely intothe magazine. Also the stop, which is thrown out of a vertical plane and engaged with both the stop bar and magazine, may become distorted. Under an incomplete operation of the retracting key 8G the same troubles and defects may arise due to a partially retracted stop. VEven when full stroke devices are associated with the key operated stop ejeet ing and reti'acting mechanism, the same defects may arise since the full-stroke devices do not insure that the operator must fully actuate the keys but only that the keys cannot be actuated a second time before the completion of the rst actuation.

One of the objects ot my present invention is to overcome the specified detects and I accomplish this result by providing` locking devices which coperate with the carriage to lock it against movement at the beginning` of an ejecting or retraeting operation and to maintain it thus locked until the operation is lso far completed that the stop that isbeing shifted has been entirely separated from the part from which it is being moved. Con- 'sequently if, when the operation, in therespect just stated, is only partially completed,

.the .operator should attempt to releasethe carriage for an additional leftward move ment either by a tabulating operation or by operating the usual release key, or should actuate the space bar, the carriage would not respond since it would be held by thelocking or restraining devices. Said locking devices `in the present instance are designed for eooperation with the retarder rack 44 and comprise a U-shaped frame or member 88 which, as 'shown in Figs. 2 and 4, 'has parallel ears 89 pivoted on a shoulder screw 90 which is secured to an ear 26a bent rearward tromV the left-hand side of the guide plate 26 and projecting laterally leftward there'- from. The right-hand ear S9 has a forward extension or finger 91 which terminates in an upwardly directed portion or locking tooth92 which is beveled or sharpened to eooperate with the notches between the teeth of the rack 44 which the tooth or. pawl 92 underlies and from which it is normally separated as shown in Figs. l and 4, owing to the act-ion of gravity on the member 88. Secured to the base of the member or loeking device 88 by screws 93 is a spring linger or arm 94 which is bent to extend downward behind the member 88 and in front ot the links 6o` and 78, said member near its lower end being provided with a bend orbight 95 which constitutes/a roundednose for -cooperation with lugs or cam pieces 9G and-97 connected to and preferably integral with the respective links 65 and 7S and designed toi.' coperation with the nose The cam 9G is comparatively longand terminates at the ytop and bottom in cam edges which are inclined to 'the front edge, the latter being substantially vertical and parallel with the front edge of the link G5 and acting somewhat like a dwell. Normally the cam 9G is above the nose 95 but so situated that as soon as the downward movement of the link G5 begins the cam will begin to cooperate with tlie nose 95 to swing the member 8S on its pivot 90 and bring the-locking tooth 92 into engagement with the rack 411-. The member 8S and the springarm 94, together constitute a lever member of the first of the ,stop ejecting mechanism in each instance by the provision of locking means which hold the carriage against movement from the beginning of the ejecting operation until the ejection is completed by the removal of the stop from the magazine; also it will be observed that the locking devices are combined in such a way with the full stroke devices that they constitute indicating mechanism for the latter, bringing to the notice of the operator, when he fails to properly actuate the key, that the full-stroke devices are in operation. On the other hand, the full-stroke devices operate toA maintain the locking device or tooth 92 in operative position until the column stop has been properly ejected, so that they vcannot act as a drag or detent to prevent free movement of the carriage.

The column stop having been properly ejected from the magazine and -pushed down in place on the stop bar, the ejector 61 will return to normal position and all of the remaining column stops will be forced together outward along the supporting rod 53 by the spring pressed follower 58 until the outermost stop is brought into contact with the adjacent facefof the member 60. It will be found-.that the ejected stop has thus been set on the stop bar at a point corresponding with the pointindicated by the usual scale andpointei-` at the front of the platen, this setting beingdue to the fact that the magazine slot-way 63 is in substantial alinement with the'left-hand or denominational stop 24, thus obviating the need of mental calculation in the proper positioning of the carriage prior to the ejectment and setting of the column stops. After the rst column stop has thus been setthe carriage is released and moved leftward until the neXt column on the work sheet or blank is brought in register with the printing point, whereupon the key 74 isagam operated` to eject and setthe next column stop, this operation being repeated until a column stop has been prop erly adjusted on the stop bar for each column on-the work sheet.

After the columnstops have been adjusted as described the tabulating operations in the course of filling in the blank may proceed as usual, the tabulator keys 32 being operated to project the denomination stops 24 horizontally forward into the path of the column stops, which will co-act to arrest the carriage in the usualfway` at the desired .tabulator positions, the lprinting keys being operated to`v fill in ,the items inA the various columns las is common. K j

' -Prior to Aresettingthe .column'stops for a different character*of'gtabulator work or for any other purposefitY is necessary as apreliminary to remove the column stops from the stop bar or clear it, as.l the expression is. Heretofore in stop clearing,operationsv itis to be understood that if preferable the i arm 110 may be formed integral with said decimal lever. rThe arm 110 extends forward and downward, being off-set toward the left as shown in Fig. 10, and at its forward end curves upward, terminating in an inclined face 112 which underlies and is adapted to cooperate with a pin or stud 113 which extends? laterally from the forward end of an arm 81a which is an extension of the arm 81 and is preferably formed integral with said arm and with the hub 82, the armA 81a extending forward from said hub and being secured .through it to the sleeve 83 so that when the sleeve 83 is turned as a result of the actuation of the key 86, the arm 81a will swing downward, causing the stud 113, acting Vagainst the face 112, to actuate the arm 110 and swing the decimal lever 21 upon its pivot, projecting `the decimal stop 24 and releasing the carriage. It will be understood that the projection of the stop and-the release of the carria e occur concurrently with the lifting of tie retractor 62; and also that the actuation of the decimal lever 21 by the key 32 is independent of the slide bar 27 associated with the lever 21, said slide bar, togetherwith the arm 29 and key lever 31 remaining una'ected by such operation of the lever 21.

' As a'preliminary to Athe stop retracting or clearing operation the carriage is first pushed to the extreme rightward limit of its-A travel. Let it'be assumed that this brings the irstror 'proximate column stop 56 on the stop bar 48 to the position shown in Fig. 7. .Thereupon the operator actuates the key 86, projecting the decimal stop 24 and releasing the carriage so that it will run leftward until the proximate column stop 56 engages with the' projected decimal sto-p 24 as shown in F ig. 8. The actuation of the key 86 isalso effected to lift the retracting head (34 but as shown in Fig. 8 the head is slightly to the left of the projected decimal stop 24 so that the column stop may co-act with said decimal stop without interference from the head 64. During the irst stage of the actuation of the key 86 the carriage will be locked against traveling movement'by reason of the action of the cam 97 and the nose 95; but the cam is short and passes upward out of engagement with said nose during the latter part of the key actuation so that the carriage is free from the control of the locking tooth. This tetu ture will be more fully discussed later on. After the two stops 5G and 2l co-act to arrest the carriage the operator releases the key 8G, permitting it and the connected parts to return to normal position and rotracting the decimal stop 24 so that the carriage as usual may move slightly lettward, bringing the proximate column stop 56 to the position shown in Fig. t), which lofates said stop 5G over the ret-racting head (Sln and in position to be retracted thereby. lf\'ext the operator again actuates the key 8G and during this actuation the link 78 as it rises, eiiectively operates the slide or retractor (32, causing the head (ist to engage.

with the column stop 56, lifting the same, disconnecting it from the .stop bar l-S and forcing it within the stop magazine.

During the lifting or retracting operation the cam 97 acts against the nose 95 to swing the locking tooth 92 into engagement with the rack lst to lock the carriage againsttraveling movement and the parts are so proportioned and related that said cam remains effective until the stop 56 has been entirely discoimected from the'stop bar. This will be understood by reference to Fig. 5 which shows the stop lifted oftn the stop bar and also shows the nose 95 at this time at the lower end of the cam 97 and just about to ride oit thesame and into the notch or depression 98. This latter step occurs during the further actuation of the key SG. As soon as the nose 95 leaves the cam 97, the locking tooth 92 releases the rack tat as shown in Fig. 6, permitting the carriage to run leftward during the further upward movement of the column stop 56 and the lifting action of the retracting head 64. This leftward movement of the carriage continues until it is arrested by the co-action of the next succeeding or second column stop 5G with the decimal stop 24 which, it will be recalled, is inoperative position at this time. Consequently if on the completion oit' the ietracting operation the operator releases the key 86, the parts will be restored to normal posit-ion and said second column stop will be brought to the Fig. 9 position ready to be retracted when the key 86 is again actuated. The operations above outlined are continued until the stop bar 4S has been entirely cleared. It will be understood that this clearing operation is caused by a series of successive actuations of a single key SG; that during the first stage of any key actuation the carriage is locked against movement and continues locked until the column stop that is being retracted is entirel removed from the column stop bar, omg away with all danger ot jamming the carriagc and bending the stop; that thereafter during the succeeding stage of the same key actuation the stop will be further retracted until it is entirely within the magazine; that during this further retraction the carriage will be automatically released and will run ireely leftward until arrested by the co action of the decimal stop with the next succeeding column stop; that at a single actuation of the key 86 a concurrent action results in the projection of the decimal deiiominational stop, the locking of the carriage, the retraction of a. column stop, the unlocking of the carriage and the free run thereof until it is arrested by the cro-action of the next succeeding column stop with the projected denoniinational stop; that the invention provides in combination, a traveling element, a carriage, a stationaryelement, trame or fixed part on which the magazine for the column or tabulator stops is mount ed, means for shifting the tabulator stop from either one of these elements to the other, and means for locking the traveling element against movement until the stop has been shifted or completely removed from the element b v which it was first supported, whetherthat element be the traveling one or the one that is relatively fixed or stationary; that the means for shifting a tabulator stop from one element to the, other is cont-rolled by a key, which same key also controls means for locking the traveling element against movement; that in the present instance said ke f is at the front oi. the machine in the vicinity oit the keylioard; that the carriage locking means is connected with the stop shifting means; that the locking devices are brought into use or rendered cflective automatically and when a tabulator stop is shifted; that the tabulatoi stop is shifted or ejected from the stationary ele;Ik ment on to a traveling stop bar or stop receiving element provided with a series ol: teeth ou stop receiving means; that. said stop bar travels in unison with the carriage, and in the present instance is rigid thereon; that said stop may be retracted or moved from said stop bar back to its support on the stationary part or frame; that the shittable tabnlator stop or column stop when on the traveling carriage adapted to engage with a key controlled cooperating stop mounted permanently on the iti-ame of the machine; that 'the two stops cooperate, when the carriage is released, to arrest it at a. predetermined point; that locking devices including nthe locking tooth 92 are provided, which devices are independent of said two stops and may be actuated to lock the carriage at said predetermined point; that locking devices are provided which constitute means tor preventing relative movement between the stop bar or stop receiving element and a stop support container or magazine, said stop bar andisaid sto support or container constitilting two re atively movable parts either of Losse@ which is adapted to. receive and support one .f

or more tabulator or column stops; and that means are provided controlled by a Single key for shifting the tabulator stop.' from the stop bar to a stop support or container an 'for positioning a second `tabulator stop relatively to said support in position to be subsequently shifted from said stop bar tosaid. support. t
