COMBINED TYFE-WRITING AND COMPUTING. MACHINE.

Specification of Letters Patent.

Application filed December'30, 1913. Serial No. 809,475.

To all whomit may concern:

Be it known that I. BURNHAM' (l. STIoK- xizv. a cltlzen of the United States, residing in .llliiabeth. in the county of union and State of New Jersey, have invented certain new and useful Improvements in Combined chines and is especially directed to computing machines having -a traveling carriage and a set of dial or computing wheels in which numbers are'r'egistered in a manner determined by said traveling'carriage, said wheels being fixed relatively to the travel of said-carriage; In said machines, which are best represented by combinedtypewrit mg andcomputin'g machines, the carriage position, but when in effective position are adaptedto be caught by the general oper- Patented Jan. 4,1916.

ato'r which'through said pins moves the computation members.

To enable the tappet on the typewriter carriage to first move the left-hand computation member to efi'ective'position, I have provided a transposition device "comprising arms adjacent the path of said tappet and arms adjacent the computation members, which arms are'so connected that when the right-hand tappet-engaging arm is actuated by the tappet, the left-hand computation member is correspondingly moved by the left-hand arm.

'mounted at the extremities of a single shaft normally travels to the left so that the numbers when written will be writtenbeginning with the left-hand digit, and then the right-hand digits will be'written one after another, while the numbers so written are registered on the computing or dial wheels, beginning with the left-hand dial wheel, and later on those to the right. "It is necessary therefore to provide means whereby a carriage which travels to the left may cause numbers first to be registered in',a left-hand dial wheel and then seriatim'in the dial wheels to the right of said left-hand "wheel. Devices for accomplishing this are called transposition devices. and my invention is disclosed as a transposition device adapted to be used in an'Underwood-Hanson combined typewriting and computing machine. in such machines. the carriage of the ordinary l nderwood typewriter travels to the left and carries a tappet which, as the carriage travels along, moves into effective p0- sition seriatim one after another computatii in i'i'lembers beginning with the left-hand computation member, so that a digit is set up on each computation member correponding to the number written at the moment on the typewriter carriage. After a number has thus been set up so that all its digits are registered on the computation members. said number may be carried into the dial or con'lputing wheels by means of a geme ral operator which drives said computation members to turn the dial wheels each to an extent determined by the digit set up thereon. The digits are set up by depressing' pins which are normally inineffcctive which serves as a bearing for all of said arms, and said arms may swing in horizontal planes and be connected by bails, said bails being of varying sizes so that a set of bails forms a compact nest adjacent the frame of the typewriting machine. Said transposition device forms a compact,

easily constructedand easily assembled de-' vice which is adapted to be readily attached to existing types of machines, and said bails may be formed of integral stamped metal shapedin such a way that each bail forms a girder in effechthus giving each 'member of the transposition device a light but extremely rigid structure.

Said arms maybe Other features and advantages will here Hanson combined typewriting and comput ing machine, showing so much thereof as is convenient for the illustration of my inven-v tion. Fig. 2 is a rear view of the same. Fig. 3 is a plan view on a larger scale showing the tap'pet effective on one transposition arm. Fig. 4 is a similar view showing the tappet ineffective during the return movement of the typewriter carriage. Fig. 5 is a view of a single transposition member of my device. Fig. 6 is a perspective view of my device assembled, in which the member shown in Fig. 5 appears with one arm at the top ofithe arms appearing in the bottom of said Fig. Fig. 7 is a fragmentary side view of Fig. 1, showing theta ppet holding a computation member in effective position.

bars 4 by means of bell cranks 5 upwardly andrearwardly against a platen 6 causing type 7 to print on said platen. Said platen is rotatable and forms part of acarriage 8 Which is normally tensioned to the left by means of the usual spring-barrel 8*, and is fed along under the tension of said springbarrel at every key stroke by means of an escapement wheel 9, said escapement wheel being attached to a pinion 10 which meshes with a rack bar 11 on said carriage. Said escapement wheel 9 is givena letter-feeding movement by dogs 12 and 13 which alternately engage it, and are connected to a frame 14 which comprises a universal bar 15, said bar beingstruck and vibratedby a heel 16 on each type-bar as the type-bar approaches the platen: Said carriage may be rapidly positioned by means of tabulating keys 17 which may form part of a decimal tabulator. Whenever a tabulating key 17 is depressed, it swings down its lever 18 to raise to effective position a plunger 19, said plunger when so raised carrying its upper end 20 into the path of a stop 21 settable on the usual rack bar 22 on the typewriter carriage. pressed, it releases the typewriter. carriage from the escapement mechanism by the usual connections, and thus permits said carriage to be drawn, along by its spring-barrel until arrested by the column stop 21 which is intercepted by the upper end 20 of the plunger 19, which upper end forms a counter-stop. The connections for releasing said carriage include a short universal bar 170, which overlies heels 171 on the plungers 19, so that every time a plunger 19 is raised said universal bar'170 is lifted. This lifting of said universal bar 170 frees the typewriter carriage from the escapement wheel 9 by lifting the rack 11 out of mesh with the pinion 10. The connections for doing this include an idle roll 172 which is journaled on a stub shaft 173, said stub shaft being swung upwardly around its pivot 174 by a link 175 which is connected to an extension 176 of said shaft and to an extension 177 of the universal bar 170. Saidcombined machine also includes dial or computing wheels 23 for computing the numbers printed in an adding column by the numeral keys 2 To provide for such computing, said wheels 23 are adapted to be turned by computation members 24: to an extent determined by the numeral keys of the typewriter. The numbers while being written are set up on the computation members 2 1 by depressing pins 25 thereon from their normal ineffective position to effective position, and then a general operator comprising a crossbar 26 comes forward and intercepts any depressed pins 25 so that said operator drives the computation bars 24 by the depressed pins to an extent determined Whenever a key 17' is de-' themes in each case by the pin depressed, and turns the computing wheels 23 by means of racks 27, said racks being formed at the front ends of the computation members 24.

The pins'25 on the computation members. or bars 24: are depressed into their effective" positions where they will be intercepted by the cross bar 26, by pin-setting linkages 28 under the control of the numeral keys of the typewriter. Said pins 25 normally stand- 1n such'staggered position to the linkages 28 that said linkages will be ineffective thereon, as best shown in Fig. l, where the pins are seen out of alinement with the linkages 28. In the adding zone, however,

the computation members 24 are shifted seriatim to bring their pins 25 into alinement with the pin-setting linkages 28, where, as best shown in Fig. 7, the pins are-directly under the linkages 28 so that when any linkage is de ressed, as is shown for one linkage in said ig. 7 ,"it depresses the pin-beneath it on the particular computation 'member which has been shifted so that the lower end of the depressed pin is in the path of the cross-bar 26. The connections for this moving the computation members-24 to bring their pins'under the linkages'28 include my transposition device, which device is operated by atappet or dog 29 mounted on the column stop 21. Said dog is provided with a cam face 30 which as "the; dog travels along with the typewriter carriage inletterextensions 35 and 36, said extensions form-.

ing integral parts of the arms aaand Each bail 34 is pivoted on the fixed shaft 37 by means of its aforesaid extensions, the latter having journals formed therein. To prevent friction, the adjacent extensions of the bails are slightly separated from each other, and for this purpose the upper extensions 36 have-washers 38 placed between them, and the whole group of extensions 36 is held in position by collars 39 fast on said shaft one on each side of the group of extensions 36. Said shaft 37 is firmly mounted in fixed brackets 40 and 41 fast in the tabulator stop casing.

v The bails 3% are divided into two groups I whereof the outer group has its upper arms thereof form a sharp angle at the journals so that the extensions proper 35 and 36 of a single bail occupy approximately the same vertical plane. The--other group of bails is arranged with its extensions reversed, so

that in said second group the lower arms 33.are nearly straight.

To makeup for the vertical spacing apart of the extensions 35 and 36, the arms formingv the ends of said extensions are (except for the arms of the central. bail) provided the setting of a column stop 21 will auto-- matically cause the transposition arms 32 and 33 to bring the computation members 24 into effective positions at points corresppnding to the columns in which writing is being done, thereby causing computation to be performed in'the proper wheels.

The computation members 24 are normally held in their rearward ineffective position by spring arms 45 which bear against shoulders 46 on the computation members, but the arms 45 are of such length that when the computation members 24 are moved forward by the cross-bar 26, the arms 45 will ride. up on the flat rearward extensions 44 of said members, and thus have no retarding effect on the operation of the machine.

The returning of the cross-bar2 6 brings back with it the computation members 24 so they will stand at their normal ineffective positions, and at the same time automatically causes a pin-restoring plate 47 to restore to ineffective position all the set pins 25. The general operator is moved for" ':rd and backward by the usualhan'dle 48 which is fixed to the usual segment 49, said segment meshing with an idle pinion 50, which pinion meshes with a rack 51on the side bar of the general operator.

Means are provided whereby the tappet 29 of the tabulatin'g stop 21 will swing idly during the return movement of the typewriter carriage. For this purpose'said tappet ispi\'oted at onthe stop 21, and during the letter-feeding movement of the carriage is held in effective position by a lug 54 against which it is normally pressed by a spring 56. said' lug bearing against the side of said tappef and keeping it from swinging out of effective position. During the return n'ioi'feiiieut of the carriage, said 1111mm s swung cnfl s pivot 753,218 seen best ii: i: lg. l, l the f'l'zifsirlls 55 (if the Can 1S 31, and so passes idly by them;

The pin-settingflinkages 28' enonnepted .to be operated b the numeral keys by the usual pendents 5 of which there is one for each numeral key, which pendent, as its key descends, strikes a wrist 58 fast on a shaft 59.. This shaft 59 carries a rock arm 60, said rock arm having fast thereon another member 61 of the linkage 28, the result, being that when any numeral key descends, it swings its linkage from the position shown in l to the position shown in Fig. 7, just above the arrow therein, thus depressing the pin 25 on any computation member 24 which is at the moment holding its pins alined with the linkages 28.

In my pending application 685,652 are contained relatively broad. claims to the construction of the bail-like or one-piece transpositionmembers, each engaging atone end the carriage or carriage-dog, and at the other end engaging its associated indexing member. The claims in this application are restricted to features not disclosed in said application 685,652.

Variations may be resorted to Within the scope of the invention, and portions of the improvements may be used without others.
