.COHPUTING- HAGHINEfCmA-NY, Olli' NEW YORK, N'. Y., A CORPORATION AOF `Naw-ironic.

To all it may comm.'

Be it known'that I ',BURNHAM C. STICK- NEY a citizen-fof the United States, residing in lizabeth, in the vcounty of* Union and State of New Jersey, have invented certain new and useful Im rovements in Combined 'Typrewriting and omputing Machines, of

w ich the following is-'a specification.

`This invention relates generally to combined vadding and typewritlng machines, and

which indexing pins or devices are' set up at the operation of-the vnumeral keys and the numbers, so indexed are subsequently carried into a totalizer o'r register; an example of this classv of lmachine beingthe wellknow'n Underwood bookkeeping machinev which is illustrated in the patent to Minton,

1,280,065, and other patents.

Thev indexing pins are usually arranged nine in a row, each row representing a` diiferent denomination. Independently operable in-setting bars` are arranged transverse aboveL the index pins, one bar connecteto each numeral key, so that any key can 'set a pin in any row-` All of these pins are normall' outof range of these setting bars; but t rough suitable mechanism the typewriter carriage operates to project the pin rows one at a time into the paths of thesetting bars. Hence,l the selection of an indexing pin depends partly upon the position of the typewriter carriage, and partly upon the selection of the key. Springs return the setting bars and the pin bars after thepin-setting operation. When all of 'the' pins have been set up for a number, a gen-4 eral operator is usually employed to advance all of the dial wheels simultaneously, each to an extent determined by the described settin of the pin in its associated row.

practice, it is important to guard against erroneous setting of the index pins, since errors of this kind are diliicult, if not impossible, to detect. One source of possible error is found in the lia-bility of the obstruction of the movement of one or two of the bars which carry the rows of index pins. The return of the bar upon which a pin has just been set may-be delayed, or the advance of the train of mechanism which connects f rxPEwmrIn-G am, conrrme vMacallan it -to the typewriter marriage,- may be hindered Inveither case .an' error is liable to occur, since all of .the pins must be in their" ferries;

intended places at the operation of the se'ttirg bar, as otherwise a wrong pin may be The return ofthe pin-carrying bar, after the pin-setting operation, is liable to be slow,

owing partly to the 4weakness of the returning-spring usually employed, and partly to l A clogging of the bar, or of the parts that must return with the bar. The bar-returning Aspring 1s not usually'of great'tension, be-

cause ltmust be overcome by. the power of the typewriter carriage in moving from one y step to'the next, and it is not desirable to retard the actlon of the carriage. Hence,`in

rapid key operation, this sluggishness of return of the pin-carrying bar will sometimes result in the next operated numeral key set# ting a p1n upon the first bar before it 'can reach normal positiqn; this resulting in faulty act1on, which it is diflicult, if not im-v possi le, to detect, so that an unnoticed error creeps into vthe computation.

To overcome this diiculty, there'is provlded a device which, at the down stroke of the numeral key, forces back to normal'posif t1on any pln-carrying bar that may have -been displaced. This is preferably'done be-.

fore the pin-setting bar descends far enough to engage an index pin, and hence there is avoided the liability of false setting ot a pin upon the returning pin bar. This clear ing device for the pin-carrying bars may be in the form of a transverse bar which is movable downwardly to engage projections on the bars, to cam the bars back. Atthe same time, this clearing or justifying device may operate to cam forward the pin-carryrying bar which is just being-advanced, so as to insure that the selected pin thereon may be properly engaged by the descending setting bar. l

' Said clearing bar is preferably operable any of the pin-setting bars orl linkages.

b y Ficr this purpose, said pinsetting bars may said carriage-'feeding mechanism, upon its return stro e, may act through said special universal bar to return promptly to `normal position the actuated pin-setting bar; and

of the typewriter carriage is controlled by the numeral keys, as well as by the alphabet keys of the typewriter. In the Underwood machine, all of the type-bars are provided with heels which operate a curved universal bar, which controls the feeding dogs that cop operate with the' escapement wheel of the 4 ated by its type-ke carriagegfbut preferably theI heels of the numeral type-bars 1 to 9 are omitted, so that said type-'bars cannot operate the uni.-

versal bar, and hence cannot feed the carriage. The typewriter universal bar cannot return to normal position withoutsimultaneously restoring the special universal bar to normal position, together with the pinsetting linkage which hasjust been actu- The adding mec anism is silenced by effecting a disconnection between the typewriter-carriage and the denomination trains which advance or displace one by one the rows of index pins', so that all of the index pins remain stationary out of range of any ofthe pin-setting bars, the special un1ver l sal bar and the clearing bar vibrating idly at the numeral key strokes. Certain features disclosed herein are disclosed in my pending application No. 260,626, tiled November 1, 1918.

Other features and advantages will hereinafter appear.

In the vaccompanying drawings,

Figure 1 is a sectional side elevation from front to rear of a combined typewriting'and computing machine of the Underwoodanson type, showing the present improvements in one form. The parts are in normal positions.

Figure 2 shows some of the parts seen at Figure 1, with one of the numeral keys depressed to cause its type to print, and also to set an index pin.

Figure 3 is a perspective rear view to illustrate the operative connections between a numeral type-key and the typewriter .universalbar mechanism, also the clearing mechanism for the bars which carry the index pins.

Figure 4 is an enlarged fragmentary perspective ofthe clearing bar andthe rear end of an index-pin bar.

, rocker is Figure .5,is an enlarged sectional fragmentary slde elevation showing the clearingbar at the end of its down stroke.

he typewriting mechanism usually comrises numeral keys 10, alphabet keys 11, ey-levers- 12, sublevers 13, and t pe-bars 14, which swing up against a platen 15 ywhich is mounted u n a carriage 16. The alphabet type-bars ave heels 17 to operate a universal bar or frame 18, which is usually 'carried at its rear portion upon rock-arms 19, and has means 20 to engage a dog-rocker 21, comprisin a pair of dogs 22, 23, which move into an out of engagement with the teeth 24 of the escapement wheel 25, the latter connected by a pinion 26 and rack 27 to the typewriter carriage 16. The dogrovided with a returning sprin 28, and tlge universal bar is also provid withr a returnin' spring29. The numeral type-bars 14, with the exception of the 40 type-bar, are illustrated as havin no means to operate the universal bar 18, t e heels 17 being cut away from these bars.

The adding or com utin mechanism comprises stems 30 pen ent om the numeral keys 1 to 9, in position to descend and engage at their lower ends rock-arms 31 mounted upon the forward ends of shafts 32,

lwhich extend `forwardly and rearwardly,

said shafts carrying a set of driving arms 33 which operate pin-setting linkages, of which there are nine, one for each numeral or digit key. These linkages comprise upper sets o Itransverse horizontal bars 34, having pins 35 which are `engaged by said driving arms 33, and also compriselower sets o horizontal transverse arms or bars 36, which are the inf-setting bars above referred to. These ars 34, 36 are connected by bell-cranks 37, 38 at their left-hand and right-hand ends, to form parallel motions or linkages. Whenever a key is depressed, the linkage is moved thereby in a direction to depress the bottom bar 36, whose function is to engage the corresponding index pin 39 in any of the rows into which the set of index pins is divided. Each row'of index pins is carried upon a separate bar 40, which extends forwardly and rearwardly of the machine, there being nine pins upon each bar, one for each digit. The pins in each row are separated suiciently to permit the t en ged oneafter another by 'said dog. AEach-A f jac is vibrated by the dog, andthereby sets forward the associated pin-bar 40,l tcv which it is usually connected by. means of a link 43, a lever 44, a transposition device and l a bell-crank 46. V

It has been the practice to restore'ithe numeral keys to'normal positions by means. of springs 47, and the pin bars-40 Vby means of s prin s 48, .these springs-bein in practice of re atively light tension.` here isprovided a returning device for-the pin setting linka es, consisting of a universal bar exten ing'fore and .aft of the machine, and

operable by any of the pin-setting bars 36.

lThis bar 49 is used in-connection with the are mounted on a shaft 51, thereby forming a bail or rocking frameg'and an arm 52 may l extend from said framefin position to drive upwardly athrust-link 53, which, at its upper end, is pivotally connected to a lever 54v which is usuallyfound in the typewriting lmachine, andhas a driving connection by meansof an -arm155l with the rock-arm or frame 19 which -carries the typewriter uni- Y versal bar, so that at thefoperation of any said typewriter universal bar or frame is- 'ven' its customary ba ckward movement. spring 50 tends tohold universal bar 49 in raised position. f

At lthe release of the numeral key, the typewriter universal bar. or frame 18 reacts upon the special universal bar frame 49, vand thereby upon the pin-setting bar 36 which at the moment is in engagement with said special universal bar. Through these .various instrumentalities, the pin-setting -bar may be restored promptly and with cernumeral key,

tainty, and hence proper clearance' between said vbar and the index pins39 is assured, so thatvthere-will be no interference either with the return of one pin-carrying bar 40 to normal position, or with the yadvance of the s ucceeding pin-carrying bar to setting osition.

The arm 52' and the link 53 may e omitted if desired, in employing certain features of the invention, and in that case the heels 17 meg7 be restored to the numeral type-bars.

om an arm of the special universal bar frame extends an elbow 55. which is connected by a link 56 to one of the arms of a bail 57, the cross-bar 58 whereof is employed as a clearance-bar for justifying the pin-carrying bars 40. This clearance-bar comprises preferably a set of beveled teethv 59, one for each of the pin-carrying bars. Each of the latter may have a lateral projection 60, which may be beveled on its forward side at 61, to operate as a cam, whereby when engaged by a tooth of the clearing bar, it will be' oammed back to normal position; the clearing bar teeth normally vibrating up and down just infront of the row of projections r v'60. Each tooth lof the clearing-bar is prefy the carriage through the described train Aof connections. The clearance-bar 58- may A thus operate to complete the -movement of l the advancing tooth-carryingbar promptly,

so that it will present the selected pin 1n bar 36. bar will .also serve to lock the selected toothcarrying bar in advanced position` and the l others in .their normal positions.

When it is desired to silence` the Vadding mechanism, the usual non-addkey'v''may y be pressed rearwardly, its rod-164 'operating' a leverorarm 65, which is usuallypivoted to the machine, and is provided with a short arm 66 vwhich engages a' cam 67 todepress ing osition. the -denomination-selecting dog ence, when said non-add key is pushed in, these dogs 41 are silenced, and hence none ofthepin-carrying bars 40 is displaced, and

a cam-roll 68 .which usually serves'the purvpose of elevating or holding up to its work- 1 l the operations of the pin-setting linkages t are idle. However, the pin-setting linkagesy all operate the special universal bar 49, and' thereby thetypewriter universal Abar 18, so

that typewriting proceeds the same as if the numeral type-bars had'heels 17 tooperatethe universal bar 18. The movement of the clearance-bar will be idle.
