UNITED STATES PATENT OFFICE WALTER WRIGHT, OF NEW YORK, N. Y., ASSIGNOB TO UNDERWOOD COMPUTING MACHINE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

COMBINED TYPE-WRITING AND COMPUTING MACHINE.

Specification of Letters Patent.

Patented June 25, 1918.

Application filed December 24, 1910. Serial No. 599,188.

To all whom it may concern:

Be it known that I. WAL ER WRIGHT, a citizen of the United States, residing in New York in the county of New York and State of New York, have invented certain new and useful Improvements in Combined TypelVritin and Computing Machines, of which the fol owing is a specification.

Thisinvent-ion relates to combined typewriting and computing machines, and particularly to that class in which writing alone is done at one portion of the line, and both writing and computing at another portion of the line of writing.

In my former applications, I have illustrated a gang of computing wheels of extraordinary length, so that there was one computing wheel for every letter-feeding movement of the carriage. This permitted the placin of the columns at any desired portions 0 the work sheet, and the comput- 3d letter-feeding ing of all the numbers as they were written. he object of the present invention is to improve the machine, especially, with a view to adapting it for paper carriages of extraordinary widths, such as accommodate paper twenty inches or more in width for instance, in which machines it would not be desirable to provide a computing wheel for every movement of the carriage, especially since, in such machines, it is generally desired to add only at a few points along the line of writing.

To accomplish this object, I provide a gang of computing wheels of substantial length, but not so long as the length of run of the carriage, and preferably equal in number to only a. small fraction of the number of letter-feeding movements of the curriuge, but still having the computing wheels sutliciently' numerous to accommodate separate footingls of each of several columns of figures, eac column running into the millions, an to permit such columns to be placed at difierent positions along the computing gang or head.

I also providea master wheel for turning the computing wheels, and arrange for relative travelin movement between the master wheel and is ie. gang of computing wheels; in the present instance the master wheel becarriage to continue to the end of the line of Writing. I also arrange for the typewriter carriage, when returning, to pick up the master wheel and to return the latter to its initial position; and preferably, I provide means to enable the typewriter carriage to drop the master wheel again, so that the typewriter carriage can complete its return to begin a new line of writing. Other features and udvanta es will hereinafter appear; and certain eatures of the invention ma be used inother connections.

In t e Underwood typewriting machine, numeral keys 1 and alphabet keys 2 o erate through levers 3 and 4. to swing type ups 5 upwardly to strike against the frmf'of a platen 6 upon a carriage 7, which is driven y a spring barrel 8 and is controlled through said here by escapemen t mechanism, including a melt J on the carriage. and also including a pinion 10 meshin \vithsaid rack and connected to an escapement pinion 11. Key-controlled .dogs (not shown) cooperate with said wheel 11 to feed the curriege.

The tabulator in said Underwood machine comprises keys 12 mounted on levers 13, the rear ends of which thrust up rods ll. having at their upper ends stops 15 to be projected up into the path of an adjustable column stop 16 mounted on a rack 17 supported on the carriage 7; the rack being toothed on its to and bottom faces. and the eoluum stop being of forked construction to embrace the rack bar. As each tabulat-ing rod ll rises. it swings a universal bar '18 about a pl\'ot 1!) and pulls down a link 20 which is connected to a lever 21, the latter pivoted at :22 and carrying on its forward end a. roll to lift the carriage feeding rack 9 about its hinge 24, so that the carriage may run freely independently of the letter-feeding mechanism until arrested by the coiiperation of the column stop 16 and the selected counter-stop 15.

As the numeral keys 1 are operated. a vertical drive shaft 25 (Fig. 3) of the computing mechanism is rotated through varying distances, depending upon the key depressed. This shaft carries a pinion 26 in mesh with a pinion 27, which is fixed upon the end of a shaft 28, towhich is splined a master wheel 29, having opposite teeth 30 to engage internal teeth 31 formed on a series of computing wheels 32, said wheels mounted in a casing 33 and meshing with gears 31 formed on number bearing wheels Saidmaster wheel 29 is caused to travel stepby-step so that it may be presented to the computing wheels in succession, beginning with the left hand wheel at Fig. 3, that is, the wheel of highest denomination. For this purpose, the master wheel is swiveled or joined at 36 to a hollow arbor 37:

which is fixed rigidly upon a standard 38 forming art of a computing carriage forward of t e typewriter carriage; said stand ard erected upon a tube 39. which slides upon a rail 40, and also having a bearing 41 .to slide upon a parallel rail 42; said rails extending from a block 43 secured upon a bracket 44 which is attached to rods 45, 46. usually forming part of the typewriter framework. The opposite end of the tube or sleeve 39 is secured to a, head 47 also sliding upon the rail 42 and carrying an index 48 to indicate the number wheels 35.

Upon this computing carriage is fixed, by its ends, a rack 49, which forms part of the means for connecting said carriage 38, 39 to the typewriter carriage 7. This rack 49 is driven by a gear 50 fixed upon the forward end of a shaft 51, the rear end of said shaft carrying a gear 52, and the latter being connected by a gear 53 to a rack 51 formed on a sliding bar or carriage 55; the latter having means for attachment to the paper carriage 7, so as to move in letter feeding direction therewith; and the rack 49 moving in the opposite direction, together with the master wheel 2 so that numbers of higher denominations are tirst written and computed, then numbers of lower denominations. The bar 55 runs upon grooved guiding rolls 56 pivoted on the framework back of the typewriter carriage; other grooved rolls 57 being provided to engage the top of the bar' whereby the latter is prevented from displacement, laterally or vertically.

Pivotcd at 58 to the rack-bar 55 is the arm 59 of a hook 60, the latter having a catch or lug 61 for engagement with the column stop 62 at a point forward of the counter-stops 15. At Fig. 2, the hook is shown in full lines as held up by a spring fin er 63 (hearing in a notch 64 in the bar 55 and in engagement with said column stop 62, the latter anay pull the hook to the right at Fig. 2, or in letter-feeding direction when the carriage is fed by the operation of the keys 1 and 2, or any of the decimal tabulator keys 12. The column stop, or other carrier upon the carriage 7, pulls the hook 60 and the rack 55 to the right, rotating gear 53 and effecting a reverse rotation of the gears 52 and 50, thereby driving the computing carriage rack 49 in the opposite direction. This movement continues until a releaser 65, pivoted at 66 upon the bar 55, encounters a stop or abutment 67 fixed upon the framework. Continued mov'ementof the carriage 7 and bar 55 causes said releaser to turn about its pivot 66 to the dotted line position seen at F 1g. '2, thereby depressin the, hook 60 to disengage the catch or toofii 61 from the carrier or lug 62, and permitting the carriage 7 to continue in letter feeding direction, so that the line of writing may be completed.

As soon as the tooth 6'1 escapes from the column-stop or lug 62, the spring 63, which has been put under tension by the releaser 65. reacts and lifts the hook 60, turning the releaser 65 back to normal position against stop 65 and incidentally thrusting back the bar 55 to ermit the. return movement of the releaser it out its pivot 66. The hook 60 is supported against displacement by a headed screw 68 threaded into the bar 55 and passing through a slot 69 in the hook. 1

It will be understood that in traveling from the full line to the dotted line position at Fig. 2, the hook 60 has moved the master wheel 29 past all of the computing wheels at Fig. 3, stopping at each wheel, and that the master wheel has turned the successive wheels to an extent determined by the keys 1 as aforesaid.

\Vhen the carriage 7 is run back to begin a new line of writing, the c'olumn-sto or lug 62 engages the tooth or lug 61 on te opposite side thereof (the right hand side at Fig. "2) and thrusts the hook toward the left at. Fig. 2. that is, in the direction in which the paper carriage 7 is returned. This so that drives back the rack bar 55 and turns the gears 53, 5:2, 50, and moves the computing rack *9 toward the right at Fig. 5 to begin a new computation. T his movement continues until an inclined edge 70 upon the hook strikes an interceptor or roll 71, which cams down the hook to release it from the column stop or member 62; whereupon the carriage 7 may be driven still farther toward the left at Fig. 2 until it is in position to begin a new line of writing.

Upon writing the new line, the typewriter carriage will travel independently of the computing carriage until said column stop 62' strikes the upper portion 70 of the inclined edge of the hook 60, thereby forcing the book down until the spring 63 snaps said hook up, with a notch 72 therein fitting over the bottom edge of the column stop 62. Said stop may be so placed that upon depressing any tabular key 12, the paper carriage and the computing carriage will be brought to the desired decimal position for beginning writing the numbers to be computed. The numbers will then be autostrikes a pin 73, Fig. 3, adjustably secured by a screw 74 in a plunger or buffer 75, and presses said plunger toward the left at Fig. 3, until the disengagement of the catch 60 from the carrier or lug 62 occurs. Thereupon a spring 76, coiled about the stem 77 of said plunger, projects the latter to normal position, and forces the carriage 38 to the right at Fig. 3, and the bar 55 to the right at Fig. 2 sufficiently to enable the hook or catch 60 to rise to normal position; the' paper carriage 7 in the meantime completing its return to begin a new line of writing. The pressure of the/spring 76 may be regulatedby a screw 78. This spring serves to move the carriage 38 until the latter is arrested in initial or normal position by a snap-tooth 79 held upon a spring 80 secured to the framework; said tooth being beveled and' engaging a beveled notch 81 in theend of the rack 49. When the carriage is in this position, the index pointer 48 ma stand ust to the left of the computing w eels, as seen at Fig. 3; and upon the paper carria e being released by the decimal key 12, t e

matically computed while they are being adjustable column stop or lug 16 on the typewritten.

The work for which this machine is designed is that of making out railway reports which vary greatly in character, both in widths of columns to be computed and in the position of said columns with reference to the descriptive or narrptive matter to be written in connection with them, because said descriptive matter sometimes comes at the right of several computed columns, and sometimes at the left of several such columns. The dial or number bearing wheels 35 are herein shown as covering a range of upward of forty letter-spaces of the type writer carriage, thus permitting the separate footing of four or more adjacent columns of figures each running to the millions. Further, owing to the fact-that the dial wheels 35"are connected in a continuous carry-over train, said columns may begin and end at an points within the range of said dial whee s, and adjacent columns may vary inwidth' to any extent so long as they do not overlap. As set forth earlier in this specification, said columns can be located at any point along the travel of thetypewriter carriage, apd said point 18 determined by the stop or big 1' The only limitation therefore on the numbelgposition and character of columns which thisiuachine will compute is that the printed digits in the .columns shall all completely lie within the range of the dial wheels 35,

and that said columns shall not overlap onto each other.

It should be explained that when the hook or catch 60 is being depressed by the stationary roll 71, the computing carriage 3B carriage will engage the tooth 61 on the hook 60 and be caught in 'the notch 72, so

that when the paper carriage 7 is arreste by the projected decimal or other stop 15, the computing carriage is also arrested in position to compute the number written in the proper column or place on the worlg sheet.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others. as for instance, the releaser 65 may be used whether or not the hook 60 is returned by the carriage when the latter is run back to begin a new' line.

The tens-carryin mechanism, as set forth in certain of my ormer applications, may

-said roll serving to assist the three-part member to com plete the tens-carrying operation; a detent 87 seating between the lobes on the member 85 to complete the final ortion of their movement, to hold them against jarring. This rubber roll 86 is on a shaft 88 on which is a pinion 89 meshing with a pinion 90 forming a part of a train of gear;

ing to a constantly revolving motor (not shown). As set forth in said applications,

said motor rotates the master wheel through distances controlled by the keys, but the mechanism which accomplishes this result is omitted for the sake of clearness.
