COMBINED TYPEYBITING AND COMPUTING MACHINE.

To all whom it may concern Be it known that I, Jorm WALDHEIM, a at Elizabeth inthe county of Union and ate of New erse have invented certain new and useful m rovements in Combined Computing Machines, of

oh the following is a specification.

This invention relates to improvements in combined typewriting and computing machines, and especially to the kind known as the Underwood Addendagra ih disclosed in the application of Henry L. itman, Serial hlo. 24,390,1ild April 28, 1915, (now Patent "No. 1,308,506, dated July 1, 1919), in which one or more totalizers traverse a relatively' fixed master wheel; the totalizers being arranged to travel with the typewriter carnage; suitable tabulating mechanism, comprising column-stops, being also pro vid (1.

, More particularly the invention relates to punctuatimi space skipping devices for such machines.

In carrying out this invention, key-set column-stops are preferably used, and provision is made to set the column-stops to effective positions by a key in the keyboard of the machine, so that they may in one of said positions control the escapement for double spacing by engaging with an inter:

mediate actuating member to shift a dogarresting element forthe loose dog of the usualcarriage escapement; each of the column-stops being adapted to be engaged in either one of its effective positions by co 'ope'rative stops of the tabulating mecha- Toset the column-stops to a plurality of variable movements, the extentof said movements being limited by a shlftable stop pression' of said ey. When, however, the 5,

c in a-eom cally' shi when thestop-setting key is actuated while effective positions, the stop-se'ttmg key has normally ermits the minimum 'decarriage is moved to the decimal'position uting zone, said stop is automatited relatively to said key, so that the carriage is in said decimal position, it is moved' through a' greater extent, thus transferring a proportional amount of movement to the column-stop being set to bring. 1t into range of the intermediate actuating member.

Application filed November 22, 1918. Serial No. 263,667.

The shifting of the stop for the stop-setkey may be controlled by the carriage referably by the totalizers carried there y, so that only the stops corresponding to the decimal positions of the totalizers may be set to an esca'pement controlling position. To 'do this, each totalizer may be provided with a cam to engage with a suitable lever connected with the shiftable stop for the stop set key; the engagement between said cam and said lever taking place when the decimal position of the totalizer is moved to a letter-space position correspond-- ing to the printing point i The intermediate actuating member, which controls the arresting element for the loose dog of the escapement, is so positioned that it will be engaged only by the columnstops when they are set in their lowermost eifective position, said actuatin member being provided with a series oi? tappets or cams corresponding in number to the number of punctuation positions in each total izer, so that it may be actuated at said positions and thus move the loose dog-controlling sto 3, so as to permit a greater movement 0 the loose dog and consequently cause a double space movement of the typewriter carriage. Means are provided to move the intermediate. member to an ineffective position when the computing mechanism is silenced, or, in other words, rendered thereto, parts being in their normalTpositions.

Numeral keys 10 and alphabet keys 11 swing key levers 12 to rock bell-cranks 13 about a fulcrum 14 to swing type-bars 15 upwardly and rearwardly to cause types 16 to strike against the 'front side of the platen 18, the platen 18 being mounted on a carria 19 which is adapted to be fed from rig t to left of the machine under the influence of a spring-drum 21.

i To feed the carriage 19 step by step durlng printing operations, each type-bar 15 is provided with a heel 22, which, during the latter part of the upward swinging movement of the type-bar, engages with a universal bar 23 to move the latter rearwardly a ainst the tension of a return spring 24,

i 4, said universal bar being provided wit a cross-bar 25, which, durin its rearward movement, engages with a ogrocker 26 to move a loose dog 27 and a fixed dog 28 thereon between teeth 30 of an escape ment wheel 31, thereby permitting step-bystep movement of said carriage 19, which is geared to said escapement wheel 31 by means of a rack 32 supported on said carriage, said rack meshing with a pinion 33 having the usual one-way connection withsaid escapement wheel 31. During the rearward movement of the u per V rocker 26, the loose 0g 2 is moved out of engagement with the escapement wheel, and

i is swung leftwardly about its pivot 34 to the position indicated in 'Fi 5 by means of a spring 35, said dog27 being arrested in this position by means of a stud 36 projecting rearwardly therefromwhich engages with a stop 37 of a stop member 38, The escapement wheel 31 is at this time retained by the fixed dog 28 which has been moved into the path of the tooth 30 previously engaged by the loose dog 27. As soon as the universal bar returnsto itsnormal position the upper end of the do :rocker is moved forwardly by the spring 5, thus moving the fixed dog out of eng out with the esca andtheoose dog into the pat of thetnext part of the dog so t at it niay I This may be done as disclosed in a said Pitman app ic ment wheel L. Pitman, Serial No. 24,390. The numeral keys 10 are adapted to rotate a master wheel 41 through digit distances equal from 1 to 9, inclusive. These movements of the master wheel may be transferred to dial wheels 42 by intermediate pinions 43, which are contained within the totalizer 44, adapted to travel with the typewriter carriage, so as to bring the intermediate pinions 43 seriatz'm into engagement with the master wheel when the carriage passes through a computing zone. The totalizer mav be adjustably supported on a bar 45 which may run on a rail 46 and may be connected to the typewriter carriage by means of one or more arms 47 extending from the typewriter carrla e.

o variably rotate the master wheel, the numeral keys are provided with plates 48 having cam slots 50 therein which var (in shape, so as to rock a universal bai 51 through different angular distances according to the value of the numeral key; said universal bail forming part of a differential rocking frame 52 having a rock-shaft 53, which serves as a fulcrum for said frame. Said frame has connected thereto a vertical link 54 which is pulled downwardly, when said differential frame is rocked, to rock a bell-crank 50 about its pivot 56 to drive a rack 57 forwardly by meansof a link 58, said rack 57 meshing with a pinion .60 to rotate a shaft 61 having secured thereto a gear wheel 62, which ma mesh with any one of two pinions 63 an 64, 120 rotate the master wheel 41. for addition and subtraction, respectively,

When the driving rack 57 has been'moved forward an amount equal to the value of the actuated numeral key, it is ermitted to dro out of en agement with t e pinion 60,

be returned to its normal position.

ation. It will be seen by inspection of Figl that the totalizer 44 is provided with t punctuation places, one between millionsand hundreds bf thousands, one between V thousands and hundreds, and place between units'and cents. Instead of a decimal causing the operator to write these punctua-' tion marks at these places "while. t ingj a number, rovisi riage to eed' t letter-space distances thus skipping the pi hctuation places and leiiving n' is made to cause t e can.

.- 4, 12o rec blank spaces on the work-sheet where punctuation marks might have been written.

This may be done by devices on the carriage and preferably column-stops 65, which engage with a bail 66 having cams or tappets 67, one'for each punctuation position.

These tappets may be engaged when the carriage passes through a computing zone by the column-stops 65 to swing the bail about its pivot 68 against the tension of a suitable return spnng 70. A forwardly projectingarm 71 of said bail 66 pulls upwardly on a link 7 2 connected to a rearwardly projecting arm ?3 of the stop member 38, to swing the latter about its pivot 74 and bring a second stop 7 5 into effective relation with the loose dog 27, while the first-mentioned' stop 37 is taken out of elfective relation therewith. Thus the stop member 38 is shifted and held in its shifted position in the millions position thousands position and units position. pon typing the mini her in .either one of these three positions, the universal bar 23 is again moved rearwardly to release the loose dog 27, which is at this time permitted to move leftwardly a greater distance to the Fig. 6 position where it is arrested by the rounded pertion 76 of said loose dog which strikes the second stop 7 5 of said stop member.- 1t

will be seen by an inspection of Fig. 6 that set type, in which there is one stop for each letter-space position of the carriage. the stops being supported on a stop-bar 79 secured to the typewriter carriage. The column-stops 65 normally occupy their upper- 4 termediary of a IinkBlbOimected most or ineffective positions. When it is desired to set the column-stops" to an effective position, the carriage 19 is moved to 'the various columnar positions and ma be positioned'in each column b imeans o the usual; scale and pointer, not s own. A stopset ,key 77 is thenactuated to swing a key ilever 78 and rock a shaft 80 throufirthe in- M #3 1 am 82 extending from said shaft, theroclr-shaft :being rovided :with another arm 83, which pulls ownwardly on'a bar 84;, having at its an effective position. moves the carriage to the next columnar position and proceeds to set another columnstop in the'same manner. After all of the column-stops have been set, the carriage may be rapidly positioned in any denomina tional osition of a column, by means of a denominational tabulator having cooperativc stops in the form of plungers 86 which may be moved upwardly into the path of the effectively set column stops by key levers 87 depressibleby tabulating keys 88. When a tabulator key 88, is depressed, the plunger 86 actuatedthereby engages a universal bar 90 to rock a shaft 91 and'cause a downward pull of the link 92 connected thereto, thus's'winging a release lever 93 about its pivot 94' to raise the. rack 32"out of engagement with the escapement pinion 33, thus setting,' the carriage- 19 freetgf drawn leftwardly by the spring-drumY til one of the column sto'psn65 ,strikes 'the actuated plunger or cooperative sto'p' ,8Q6 gl' As hereinbefore described, the column stops 65 control the double,spacing, or in other words, the punctuation spaces .ek p;

ping of the carriage. The column-s t'ops are also used to position the carriage rapidly in places other than columns of fi ures as, for example, in columns where artlc es are tem:

ized. It will be seen that in the. latter case G there would be no need 'of skipping lette r space positions, and consequently proyisioi} is made in the present invention to permit the column-stops to be set in tw'o efiective positions, so that they may .,iie en aged either effective position by the cooperative p it.

To setthe column'sto'ps in either of their effective positions,there maybe a stophieiiiher 89 for limiting the depressions .of the stop-set key 7?. I, be controlled by adjustable ti-ave mg with the typewriter canri'age'andprej'f This stoprmemher 89 n? er-ably the totalizers 44, each totalizer provided with a tappet 88fjwhichlisefieg tive, when the totalizer ismoved'withits decimal place to a position corresponding to the printing point, to yengage with a roller 90 on a horizontal-arm 91"project inglaterally from the left hand side of the frame of the machine, said and forming part of a swingable frame ,92, pivoted at 93 and 94"; the lower en'rlfot saidfframe having a forwardly projecting, arm: 95., which engages, by, means of atpin anfl silot connection 96, with the pivotedstop'uiemher 89 toswing a stop 98' thereon out of the path'of said, key 77, so that it may befdelpres'sed through greater 'extentto move thecolumn-stop 65 to its lowermost efiectire position, and into efi'ectiverelation with the tappeted. hail or carriage-iced control- 1mg member as.

It should understood thatthc stop j98 is normally under the stop-setting key lever, and thus by the normal operation of said iio secured toa'rock-shaft -105 extendin key the column-stops are set to their uppermost efl'ective positions.

It is sometimes desirable to render the computing mechanism ineffective, or, in other words, silence the same sothat the numeral keys 10 may be used to type numbers without actuatin the computing mechanism. To do this, t ere is provided a non-compute/ky 100, which, when swungforwardly about its pivot 101, moves rearwardly'a link 102 connected to the lower end 103 thereof, to actuate a silencing devicg 104 mm side to side of the machine. Said si encing device 104 comprises an arm 106 which engages with an interponent107 forming part of the diflerential frame 52, so as to break the connection between the bail 51 and said difierential frame proper; this connection comprising a pin 108 on said bail 51 which projects laterally therefrom and lies in 11 notch 110 of said interponent; a spring 111- being provided to normally maintain said connection. ,It should be understood that the bail 51'is loosely mounted on the rock shaft 53 and that it moves idly about the shaft 53, during numeral key actuations when the inter onent'107 is outof engagement with, sai pin 108. The non-compute key may be retained in any one of its positions by the usual'detent or any. other suitable mea It is desirable to render the tappeted bail or letter-feedfvar ing means 66 ineffective also and. prefera ly when the computing mechanism is silenced. To do this, there is provided ,an upwardly extending arm 112 on the rock-shaft 105 to which the silencing member is secured. This arm 112 has conjaected thereto a link 113 which is drawn forwardly thereby to swing a frame 114 pivotally supported at 115 on the tabulator bracket. Theupper end of said frame haspivotally mounted thereon the tappetetl bail 66, which is carried rearwardly and out 'of efiective relation with the column-stops 65, Fig-3. The bail 66 is guided in its movements from and to its ineffective position by the link 72 which swings about its point of connection with the rearwardly projecting arm 73-01: the stop member 38.

A modified form of this invention may be used as illustrated in Fig. 7, which shows the stopsetting key lever.78 provided at its forward end with a pivoted stop member 116; Said stop member is provided with two keys 117 and 118. The stop member 116 is normally held against a stud 120 by means of a spring 121. The key 117. nearest to the front of the machine is ordinarily actuated, and is arrested in its do wn ward mo cut by a stop engagi with a stop 123; this movement 0 the ikey being suflicient to set the column-stop in .key 118 is actuated which rotates the stop member 116 about its pivot 124 until it strikes a stop 125. The key lever 78 is then moved downwardly until it is arrested b a stop 126 which strikes the fixed stop 123.

It. will be seen that with this arrangement the operator may selectively set the sto to any one of the effective positions at will.

ariations may be resorted to within the scope of the invention, and portions of the im rovements may be used without others.
