HALCOLM ELLIS, OF EAST ORANGE, NEW J'E'BSEY.

TOTAL-S16E11. DEVICE.

To all wlwm z't may concern:

Be it known that I, HAIJOOLM ELLIS, a citizen-of the United States, residing in the city of East Orange, in the State of New Jersey, have invented certain new and useful Improvements in Total-Signal Devices for Use on Adding and Listing Machines, of which the followingis a sufficiently exact description to enable one versed in the art to full understand and construct, reference bein ad to the accompanying drawings, whicdi form part of this specification.

The/object of this invention isto provide a suitable total signal for use on an adding and listing machine, having a plurality of accumulators, and for causing the device to.

print one s' al when the total from one accumulator s taken and a different signal when a total from a different accumulator Another object of this invention is to providethe mechanism for indicating whether theaccumulators are clear, and for causing a separate sign to indicate this conditionfor each of the different sets of accumulators in the machine- Beterring to the drawings in the different figures of which the same letters of reference apply and refer tov the same parts-- Figure 1 is a side elevation of this device. Fig. --2 is a side elevation ofa small detail showing the O rihting trigger. 3 is a vertical, longitudinal section through the main portionof an adding and listing machine having two sets ofaccumulators, the part shown indicating the wheels,keyboard and parts for bperating this type of a machine, both -for the addin and listing of figures and the printing 0 totals after the figures have been added.

This device is shown in connection with the printing mechanism of the addin and listingtypewriting machines, for which I have obtained Letters Patent of Great Britain, No. 28,253, December 28, 1908, and for which I have filed application for patent, the same bearing SerialNo. 470108.

The scheme for adding and listing of numbers and the printing of the totals is most clearly shown in Fig. 3the machine being provided with a keyboard having a series of keys K 51, to K 59, for each de Patented June 25;;913.

nomination, which keys'operate stops K 23, for limiting the travel backward (If a suitable rack R 50, which rack is provided with teeth on its upper and lower edges near its rear end. The rack B 50, slides insuitable grooves on the bar K 3, near its front end and past the bar R 92, also in suitable grooves, at its rear end. The rack R 50, is

provided on its lower side with a vertical slot in which a pin R 14, connected to the link P 53, extends upward and is pivoted at its upper end in the type sector -P 54,

which type sector is pivoted at its forward end to the arm 52 P, so that .when the rack R 50, moves to the rear the piece R 45, will elevate the link P 53, and so swing the type sector P 54, about its pivot in the arm52 P.

The-type on the face of the y e sector P 54, are so arranged that whenever a stop K 23, intercepts the rack R 50, the type on the sector P 54, will correspond in number to the number on the key K 51, to K 59. If

'the rack R 50, has thus moved to the rear until arrested .by the stop K 23, one or both of the adding wheels A 50, may be brought into engagement with the rack R 50, b

means of the cams A 59, or 59 A, which cams are mounted on the shafts A 1, and l A, respectively, and the partial rotation of these shafts A 1, and 1 A, will cause the adding wheels A 50, to engage or disengage the teeth of the rack R 50. It is evident, however, that if the rack R 50, is .first moved to the rear and the wheels A 50, are brought into an agement with the rack and left there while t e rack R 50, is restored to the osition shown in Fig. 3, the adding wiieels A 50, will be rotated about their pivots a number of teeth, exactly equal to the number of teeth that the racks R 50, have moved to the rear, and inasmuch as the type on the type sectors P 54, moves a distance also in proportion to the travel of the rack R60, the type on the sector P 54, will print a number corresponding to the number of teeth the wheels A 50, have been rotated.

To cause the type on the sector P 50, to print, it is necessar that the arm 52 P, be swung about its pivot P 1, so as to propel the type sector against the platen S. To do this the piece P 58, is rotated about the shaft 1, and extends the spring P 85. The movement of the piece R 45, causes the pin R 15, to release the hook P 57, from its engagement with the retaining device for the piece 52 P, and the subsequent release of the hook 57 P, will release the piece 52 P, and so permit the type sector P 54, to strike the platen S. When the racks R 50,'are restored to their normal position, as shown in Fi 3, the cams A 59, and 59 A, are restore to the position shown in the same figure, and the addingwheels A 50, are conse quently removed from engagement with the teeth of .the rack R 50. In taking a total of what has been previously added upon the wheels A 50, it is only necessary to operate the cams A 59, and 59 A, to cause the adding wheels A 50, to engage the rack R 50, prior to the movement of the rack R 50, to the rear-this being done and the rack R 50, being moved to the rear, it will travel a distance exactly equal to the number of teeth the wheels A 50, have been rotated from their zero position in adding, a suitable stop being provided to prevent the wheels A 50, from ever rotatin a distanceoeyond their starting point in axis direction; thus, if the wheels A 50, had been rotated five teeth in adding, it would rotate backward five teeth to the starting point, which would permit the rack R 50,. to move to the rear a distance of five teeth and so elevate the type sector P 54, until the figure 5 comes to the printing position. 5

On the side of the arm P 52, there is pivoted a rearward extending arm 65 P, which has at its rear end a plurality of type 'of any desired characters. In the drawing,

the upper one is marked 0 .and the lower one ismarked d. A link 64 P, connects the arm 65 P, to a lever 61 P, pivoted at 17 P, to the plate P 50, of the printing section of the machine. Mounted on this same pivot 17 P, there extends in a downward direction an arm 60 P, which extends into the path of travel of two studs 19 A, and 20 A, mounted on the side of the adding cams A 59, and 59 A. This arm 60 P, has a forward extending member, and a spring 81 P, (ex tending between suitable fastenings on its Side and on the side of thelever 61 P, holding the extension of 60 P, in contact with a pin 19 P, on the side of the lever 61 P. These parts are so proportioned that when the cam A 59, swings from the position shown in Fig. 1 to its extreme left-hand position, as is done in the case of adding, the pin 19 A, will swing the arm 60 P, to the left, and this, through the spring 81 P, will cause the lever 61 P, to move the arm 65 P,

in an upward direction until the type d on the end thereof comes to the printing position. Inasmuch as the arm 65 P, is pivot ed on the printing arm P 52, it is evident that whenever the printing arm P 52, is moved toward the platen S to print, it will carry the arm 65 P, with it, and thus cause either the type 0 or the type d to print in case they are raised to the printing position. The cam 59 A, being at a greater distance from the pivot 17 P, than the cam A 59, the movement imparted by the stud 20 A, on the movement of the cam 59 A, will not swing the arm 60 P, so far to the left as when the upper cam A 59, is operated, and this movement is just sufiicient to bring the type c on the arm 65 P, to the printing line. Pivoted on the side of the plate P 50, there is a hook 62 P, the upper end of which may engage the pin 19 P, on the side of the lever 61 P. A tail on the lower end of the hook 62 P comes into the path of a stud 21 P, on the side of the piece P 74, mounted on the shaft P 1. When the piece P 74, is in its normal position, the stud 21 P, holds the hook 62 P, out of engagement with the pin 19 P, but whenever the piece P 74, is turned to the right, the stud 21 vP, moves to the left and so permits the hook 62 P, to move toward the pin 19 P, through the effect of the spring 80 P. The left-hand endvof the lever 61 P, terminates in a cam which engages the small roller on the upper end of a bent lever 63 P. This lever 63 P, has a pin 18 P, extending through an opening in the plate P 50, and into the ath of travel of the O printing trigger 57, (see Fig. 2.) Whenever the lever 61 P, is raised, the cam on its end causes the lever 63 P, to be movedvto the left and the pin 18 P, causes the O printing trigger 57 P, to disengage the printing arm P 52. In this machine, the operation of taking a total causes the cams A 59, or 59 A, to be moved prior to the time when the lever P 74, has made any considerable movement; but in addition the lever P 74, completes the maior portion of its travel before the cams A 59, and 59 A, begin their-movement. From this it will be evident that in the process of addition, the lever P 74, moving before the cam A 59, or..59 A, permits the book 62 P, to engage the pin 19 P, on the lever 61 P, and thus lock the lever 61 P, from any upward travel, the movement of the cam A 59, and 59 A, causing only an extension of the spring '81 P. When the arm P 52, is released and the type P 54, strikes the paper, the type on the end of the arm 65 P, will reach a position considerably below the printing line, and therefore not in contact with the paper on the platen S. On the other hand, when a total is taken, the cams A 59, or 59 A, is moved before the lever P 74, and this causes the movement of the arm 60 P,and raises the lever 61 P, so that thepin 19F, is too high for the hook 62 P, to engage. The lever 61 P, is raised a' suflicient distance to cause I either the type c or. the ,ype d on the total would be printed thus, 12345 d, and

a total for the lower accumulator would be printed thus 54321 cthe letters d or c indicating that these figures are totals and that they are totals from different accumulators .and also distinguishing them from added figures, which have no letters or other sign followin them.

Now in case themachine 1s clear, the small bent arm 63 P, through the pin 18 P, will cause the O printing trigger to release the printing arm P 52, and this will permit the printing of an 0, followed by the character c or d thus OD, or OC.

Reference is to be had to my Letters Patent of Great Britain, No. -28,253, dated December 28, 1908, for a fuller disclosure of parts cooperating with the present invention. I

It is not my intention to limit tbi device to these specific arrangements of .parts shown, or to the printing of only two signals for indicating the total of two sets of adding mechanisms, as it is evident that the number may increase Without departing from the principles here shown.

Having described my invention, I claim 1.
