Specicaton-of Letters Patent. Patented Dec. 18, 191 'l'.

Application led June 9, 1914. Serial No. 848,963.

Be it known that I, RONALD MoNAn, British subject, and resident of Asnires, Seine, France, have invented certain new an useful Improvements in Combined Type-Writing and Computing Machines, of which the following is a specification.

My invention relates to writing and computing machines, and it has for its prin cipal object to provide improved means whereby numbers written in a plurality of columns can be registered 0n a single register.' In the speci c form of the invention sliown in the drawings, I have provided means whereby the Wahl adding maclune can, by the additipn of a simple and inexpensive attachment, be adapted for crossof course be underfooting, though it will stood that my invention is applicable or readily adaptable to other adding machines than the one mentioned. To the above and other ends my inveiition consists in certain features of construction and combinations and arrangements of be fully setforth pointed out in the claims.

v One embodiment of my invention is illustrated in the accompanying drawings, in Which- Figure 1 is a side elevation, partly in section, of so much of a Remington-Wahl typewriting and computing machine as is necessary. to illustrate the embodiment of my in! vention therein. l

Fig. 2 is a front elevation of the same. Fig. 3 is an enlarged detail view in fore and aft vertical section through a certain The main frame of the Remington No. 11

typewriter comprises a base part 1, corner posts supported the stationary rails 4 for the truck 5 of the typewriter carriage 1n which is mounted the platen 6. Said carriage is drawn across the machine by a spring drum `7 and strap 8, which strap isconnected with a bracket 9 of the carriage truck 5. Said truck has hinged thereto at 10 a feed rack 11 which meshes with a feed pinion 12 on the front end of a shaft, which shaft at its rea-r end has a duplex escapement wheel 13' mounted thereon for cooperation with a dog 2 and va top plate 3 on which last arey being the only ones shown. These are mounted on key levers 18 connected with type bars 20. by links 21, sub-levers 22 and links 23. Said type bars are pivoted on a t pe bar segment 24 and carry types ada te to strike against the front face of the p aten (i.

.Tabulator mechanism is provided forthe;

usual purposes of such mechanism, including that of writing numbers in columns. This mechanism, as shown in the pres-ent instance, comprises denominational push keys 25 mounted on the forward ends of push rods 26, which near their forward ends, pass through a guide 27 and -have restoring springs 28 connected therewith. Each of the vpush rods 26 at its rear end is pivoted to the lower'end of. a lever 30, all of said levers being pivoted at 31 ina frame 32, and each of them having its upper end 33 constituting a denominational stop for cooperation with one or any suitable number of column stops 34, which column sto s are mounted on a transverse toothed rac bar 35 supported by brackets 36v .from the carriage truck 5.

In order to release the-carriage when any of the tabulator keys is operated, each of the push rods 26 has fixed thereon a collar 37, which collar, when tne key is operated, is adapted to move toward the rear a transverse universal bar38 mounted on a rock shaft 40 by means of arms 41 depending from'said rock is connected by means of a push link 42 with an arm 43 extending downward from a rock shaft 44 to which itis fixed. Said rock shaft 44 has also fixed thereon an arm 45 4to which is connected a restoring spring 46. Said rock shaft also has iixed thereon an arm 47 which `is connected by a link 48 with a release lever 49 pivotedat 50 to a bracket mounted on the top plate 3, and having its shaft.V Each ofsaid arms 4l forward end formed into a shoe that under- The construction 1s riage is thus released from itsV escapement l slots cut in itsfront and rear edges a letter mechanism and is left free to run until ar- 'rested by the tabulator stops.

The Nahl adding attachment comprises a stationary frame piece or support 51 which is mounted on the top plate 3 of the typewriter by means of two brackets 52 to whichsaid frame piece 51 is secured by screws or bolts 53 (I `ig.`2), said bolts passing through perforations in the brackets 52 and being secured in place by nuts 54. An

actuator 55 is mounted on the-lower part of the frame piece 51 or, rather, said frame iece constitutes a part of the stationary ramework ofthe actuator. It is not deemed necessary to go into a description of said actuator further than to say that it'includes certain. mechanism operated b` links 56 extending upward from the key evers 180i' the numeral keys and connected at their upper ends with levers 57 'of the actjiator.

. One of the effects of the depression of one of the numeral keys, and with it one of the .'links 56, is to cause an oscillation of a rock shaft 58 and a partial rotation of a master Wheel 60. The carriage truck 61 of the Wahl adder consists essentially of a bar extending across the front of the machine and having its upper and lower parts `formed into su1table trackways for coperation with antifriction wheels or rollers 62 journaled in various ways on the frame piece 51 at. the

- middle of ythe machine; and the ends of said truck are supported and propelled by means of arms 63 extending to the right and left, f

respectively, of said truck and having slots 64 therein for coperation with screws 65 threaded into the forward ends of arms 66 rigidly mounted, as by screws 67, on the carriage truck 5 of the typewriter.

The forward part of the carriage bar 61 is formed with a dove-tail cross section as shown at 68 and on this dove-tail there is adjustably mounted an adding head 70 of the ordinary Wahl type. This adding head, register or totalizer is provided with a handoperated latch 71 adapted to coperate with teeth 72 in the upper edge of a rack bar 73 secured to the forward face of the carriage bar 6l. The teeth 72 are spaced apart in conformity tothe letter :pacing of the typewriter and the construction is such that the totalizer can be set along the carriage to any desired letter space position and there secured, and it can be moved along the carriage by hand and set to some new. letter space position by first depressing the finger piece or latch 7l.

The mechanism thus far-described is or may be that of the Remington-Vahl typewriting and computing machine, as heretofore constructed.

Inthe form of my invention shown in the'drawings I mount upon the computer carriage' 61a rackbar 74 having vertical being constructed in substantiall space distance apart, said bar, as here shown, the same way as .the column stop bar of a orin tabulator, such, for example, as thebar 35. Said bar 74 is mounted at its ends on brackets 75 secured by screws 76 to the carriage 6. The

bar 74 is fastened to the brackets 75 by means of screws 77 passing through slots 78 in the brackets 75, said slots being provided in order to permit ofthe necessary adjustment oi' the bar lengthwise of the carriage.

stops of the Gerin tabulatoigand after the general fashion of the stops 34 shown in. the present instance, except that the 'devices 80 are here shown as being set on lfrom the top of the bar 74 instead of being pushed on from the rear as the stops 34 are represented as being. The forward part of the device 80 has a hole 81 extending vertically through it, said hole being reduced near the bottomto form an annular' shoulder.` A

pin 82 has its upper end of a size adapted to play up and down in the large part of the hole 81 and its lower reduced part adapted to move up and down in the reduced part of said hole, and a light spring 83 is coiled about the reduced stem of the pin 82 and .compressed-between ,the shoulder in the lower part of the hole and the shoulder formed by the enlarged part of the pin. The motion of said pin under the influence of said spring is" limited by a collar 84 ixed on' the lower extremity of said pin where it projects below the device 80. -This collar -84 constitutes ai sort of an enlargement ofthe lower end of the pin and it also consti-y tutes al stop for the totalizer 70, as will presently be seen. The spring 83 normally holds the stop 84 at an elevation such as to allow the totalizer 70 to move freely underneath said stop so that under normal conditions the stop or stops 84would not interfere with the totalizer being adjusted from one end of the carriage' to the other. Said stops are,

however, adapted to be, depressed into the path of the upper part ofthe totalizer. Any desired one of these stops caribe pressed down to operative position by hand, and in case that mode of operation is adopted, cross-footing can be done with the device already described. I prefer, however, to depress the stops automatically as an incident to some otherope'ration. In the mechanism shown 1n the drawings, these stops arederessed upon the operation of a tabulator ey. -To this end a depressor 85 is mounted on the upper-end of a stiff rod 86 which can be suitably guided for up and down motion bracket 52 by means 88 to a lever arm integral with arms Y stops 101.

in any convenient way. As'here shown it passes through a bracket 87 which consists of a piece of sheet metal having a perforation through which the rightdiand one f the bolts 53 passes and the bracket is ses cured to the rear facev of the right-hand of the nut 54, and having its left-hand end bent around the rod 86. At its lower end said rod is pivoted at 90 which is rigidly mounted on the same hub 91 (Fig: 2),as the righthand one of the arms 41. he primary purpose of this arm 90 in the Remington machine is to operate the key-lock forming part of the line-lock mechanism. Said arm 90 is arranged to depress a fiat sprin arm 92 which is secured upon the upper e ge of a sheet metal bar 93 which at its ends is 94 pivoted in the base 1 of the machine on pivot pins 95. The lower edge of this line locking bar 93 is bent toward the rear to constitute a {iange 96 adapt ed to coperate with undercut brackets 97 on the printing key levers to lock the same whenever one of the tabulating keys is operated. This line locking bar 93 is also adapted to be operated by the typewriter carriage at the end of a line of writing through certain intermediate mechanism, none of which is shown except the lower end s of a link 98, which link is connected with one oi the lever arms 94. The construction is such that when one of the tabulator keys is operated and the arm 90 is thereby moved downward, the rod or bar 86 is also moved downward, depressing the member 85 to the position shown in dotted lines in Fig. 2 Thismember at its two ends is Jormed with bevel's 100. The construction is such that when the carriage moves at a time when one of the tabulator keys is pushed in, then lany of the pins` 82 that moves under'the device 85 will be depressed, asshown in dotted lines in Fig. 2, bringing position to arrest the totalizer 70. The depressor 85 will be restored to normal position by the spring 46, but an additional spring acting more directly on said depressor, can be added if desired.

The two. eXtreme positions of the -totalizer on` the carriage can, if desired, be defined by another form of stop which does not require to be depressed, and I have shown two such These are of the sort that are the Wahl machine, each already in use on.

of two parts slidably conof them consisting nected together and controlled by a spring 102, tending to cause stop device to tol shorten the tion of said stop the two parts of the move toward each other so as said device. The lower secdevice comprises a hook the part 84 into 103 adapted to catch under the lower flange of the dove-tail 68 and the other section comprises a similar hook adapted to catch over the upper dove-tail 68. Said upper sec` tion also comprises a tooth 104 adapted to engage spaces between the teeth 72 of the rack 7 3. These stop devices are so constructed that one of them can. be located at any letter space position along the carriage 61 by catching the hook 103 ,under the lower dovevtail and stretching the device against the pressure of the spring 102 until the upper hook is caught over the upper dove-tail 68 when said spring'will draw the tooth 10i into engagement with the rack 73. In Fig. the totalizer is shown against the lefthand one of these stops 101, which thus defines the extreme left-'hand position of said totalizer and another one of said stops is shown to define the extreme right-hand position of said totalizer. As was said above, these stops have heretofore been used on the Vilahl machine. l have shown three stop devices 80 and two of the stops 101, the whole combination defining live adding columns. ln practive five column stops 31 would be mounted on the column stop bar 35 in the rear oi" the machine in positions harmonizing with those of the stops 80 and 101.

The operation of the machine is as fol? lows :-The totalizer 7() is set against the left-hand stop 101 as shown in Fig. 2 and the tabulator is' operated, bringing the typewriter and computer carriages into position to write anumber in the first adding column and to add it on the totalizer. When this number has been written and registered, the appropriate one oi'ftbe tabulator keys is again operated`r causing" the typewriter and computer carriages to-move down to position for the next adding column. `The operation of this key not only works the typel writer tabulator in the ordinary way but it also moves the depressing device 85 to its dotted line position, Fig. 2, with the result that the left-hand one of the three stop devices moves under said depressor and has its pin 82 moved downward to position to control the manual setting of the totalizer. The operator does not instantly release the Y tabulator key 25 but while holding it in its operated position manipulates the latch 71 and moves the totalizer 70 toward the right until it is arrested by the part 8i of the lefthand stop device. The operator then lets go of the latch 71 which is instantly moved to latching position under the impulse of' the spring provided for the purpose. The operator then releases the tabulator key, allowing the depressor 85 to move back to its normal position and this also allows the pin 82 to be elevated to its normal position by its spring 83. The second number isI then written and added in the ordinary way, after which the tabulator is again operated,

ll() Y causing the second pin 82 to lmove under and to be depressed by the depressor 85. The first pin 89. has by this time moved away from said depressor and is no longer in the path of the totalizer. The operator can therefore, While maintaining pressureon the tabulato'r key 25, move the totalizer to the right until it is arrested by the second pin 82. The third number is then wrltten, after which the typewriter tabulator 1s again operated andthe totalizer is again moved, this time until arrested by the third pin 82.; the fourth number is then written after which the tabulator is again. operated, and the totalizer moved over agalnst the right-hand stop 101, whereupon the last number in the list can be written and registered. tow ard the left past the stops 85 and against the left-hand-stop 101, the springs 83 which elevate said stops 84 being included in the means whereby this can be freely done. The carriage is returned to the right and the paper is line-spaced, whereupon the machine,

1s ready forl writing another line of numbers and adding them into the register. Means are provided, including the depressor l85, whereby, in the -course of the writing and adding of said line of numbers, the totalizer can be set back toward the right against the stops, one after the other.

.It will be perceived that I have provlded very simple and easily added means for adapting the -Wahl adding machine for cross footing. It will also be readily understood that means working on the same principle can be applied to machines which in some respects diier quite widely from the Wahl machine. In a machine in which an adjustable totalizer is mounted not -on the carriage but on the stationary framework, the stop devices provided for guiding the setting of the totalizer would of course also be mounted on the stationary framework and in case it was some other part of the computing machine than the totalizer that required to be adjusted, the corresponding changes would of course be made. lSome ofV the devices shown are'applicable to machines in which the re-adjustment or're-setting of the settable part of the com uting machine is done automatically. arious other changes can bemade in the details of construction and arrangement without departing from my invention.
