CASH REGISTER AND lNDlCATOR.

SPECIFICATION forming part of Letters Patent No. 480,615, dated August 9, 1892.

Application filed October 31, 1891. Serial No. 410,515. (No model.)

To all whom it may concern.-

Be it known that I, HENRY G. ONEILL, a subject of the Queen of Great Britain, and a resident of Louisville, in the county of J eiferson and State of Kentucky, have invented certain new and useful Improvements in Cash- Registers; and I do declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

I 5 Figure 1 of the drawings is a vertical transverse section. Fig. 2 is a detail view of the roll. Fig. 3 is a longitudinal section on line 00 as, Fig. 1. Fig. i is a detail view of ratchetwheel. Fig. 5 is a top plan View, partly in section, on line a .2, Fig. 3. Fig. 6isasimilar view with an increase in number of key-levers.

This invention has relation to adding-machines; andit consists in the construction and novel combination of parts whereby it is es- 2 5 pecially adapted to provide an adding attachment to cash-registering machines in which the items are registered and indicated seriat'im, its special function being to show the total of all the transactions at a glance.

0 In the annexed drawings, the letters A A designate a series of key-levers provided with finger-pieces containing such figures or symbols as are generally in use in cash-registers. At the end of each lever it is provided with 3 5 an arc-shaped ratchet-arm A, having on its outer or inner edge, the latter being preferred,

teeth corresponding in number to the denomination of the key. At right angles to said series of key-levers and above the same, resting thereon, is a transverse bar Z, which is provided at its ends with springs Z, whereby it is made to exert downward traction on the inner branches of said key-levers to cause any key to assume its normal position of rest after 5 action. This spring pressure-bar is provided with arms Z which are pivoted to the frame or to the bar upon which the key-levers are pivoted, as shown, thus giving them sufficient length to insure the uniform movement of the bar and equalize its spring action.

Above the key-levers and in proper relation to the arc-shaped toothed arms A thereof is located a transverse fluted roll, toothed cylinder, or shaft B, which turns in bearings at its ends and is common to all of said key-levers. At one extremity of said fluted roll B is a toothed wheel B, having a ratchet-and-pawl connection with the fluted shaft, in order that the fluted shaft may turn in either direction, while operating the toothed wheel in one direction only. Near said fluted shaft and arranged in approximate position parallel therewith 1s the series of adding-wheels, which are pivoted in suitable supports V. The toothed wheel B is a bevel-wheel,preferably, and is in gear with the pinion c of the first adding-wheel C, which maybe marked with the figures O and 5 alternately. This adding-wheel is provided with a carrying arm or projection 0, extending outward between each 0 and 5 mark of the wheel sufficiently to engage the next wheel C of the series when the 5-mark has moved past its reading position. The other adding-wheels of the series are numbered from 0 to 9, inclusive,the figures being arranged on their peripheries, respectively, at regular intervals, and each of these wheels has a carrying arm or spur c", projecting outward sufficiently to engage the teeth of the next wheel when the 9-mark of the wheel being operated has passed the reading position.

For larger machines, wherein it may be found desirable to have keys ranging from the five-cent limit in multiples of five up to ninety-five cents, nineteen keys will be re- 5 quired for transactions involving less than one dollar, the highest in value of these keys being marked 95. The arc-racks of the keys will have the proper number of teeth to correspond with the values of the keys; but the 9 first adding-wheel C of this series may be marked to indicate the operation of any one of these nineteen keys, and to that end may be of larger diameter than those hereinbefore described and have upon its periphery the marks 00, O5, 10, 15, &c., up to 95. On this wheel, however, there will be but one carrying arm or projection 0', designed to e11- gage the next wheel when the ninety-five-cents mark has passed its reading position. The I00 other adding-wheels of this series may also be of larger diameter and have two sets of marks ranging from O to 9 on their peripheries and two carryingarms, whereof each one comes into action when the 9-mark has passed its reading position.

In connection with the journal portion of the fluted shaft is a ratchet-wheel D, which is fixed on said journal, and in engagement with said ratchet-wheel is a pawl (l, which is connected to the beveled wheel B, which is otherwise loosely mounted on said shaft. WVhen the fluted shaft is turned by any one of the keys, its ratchet D through its engagement with the pawl 01 of the bevel-wheel B turns the latter to actuate the adding mechanism. When, however, the pressure on the key is released and it returns to its normal position, the fluted shaft is by the arc rack of the key turned backward, but the wheel B retains its position, as its pawl becomes disengaged from the ratchet-wheel D, the holding spring or pawl (1 being sometimes em ployed to keep the bevel-wheel from moving backward. This holding spring or pawl is not regarded as always essential, as the triotional engagement of the bevel-wheel with the gearing of the adding mechanism will usually be sufficient to prevent any backward movement of the bevelwheel.

The operation of the machine is as follows: Vhen any key-lever is depressed, its arc rack, engaging the fluted shaft, moves the bevelpinion through an arc comprising the number of teeth correspondingto the denomination of the key struck, and this movement is conveyed by said bevel-pinion to the addingwheels.

Mechanism for insuring the full stroke of each key may be provided in connection with this adding-machine very easily, as indicated at Z. So, also, indicators may be readily applied, as represented at Z or otherwise, and devices for preventing the operation of more than one key at one time, as at Z but it is unnecessary to enter into a detailed description of these parts, as they have been made the subject of other applications for patent, and for the further reason that the adding mechanism herein described may be used for other indicating devices, key-arresters, and auxiliary mechanism found necessary or desirable in machines of this class.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

1. In an accounting-machine, the combination,with a series of key-levers, their are racks, and a transverse fluted shaft operated upon by said racks and common to all the keylevers, of a series of adding-wheels turning in planes at right angles to that of said shaft and.normally disconnected therefrom and a bevel toothed wheel loosely mounted upon one endof saidshaftandhavingaratchet-and-pawl connection therewith, whereby said wheel is carried with the shaft upon the forward revolution or movement of the latter, but is disconnected therefrom during its backward revolution or movement, said bevel-wheel gearing with a toothed wheel of the addinggear, substantially as specified.

2. In an accounting-machine, the combination, with the key-1evers,their arc racks having teeth corresponding in number, respectively, to the value of the respective keys, of a revoluble fluted shaft common to all of the keys and engaging said are racks, a bevel toothed wheel loosely journaled at one end of said shaft, its ratchet-and-pawl connection therewith, a series of adding-wheels turning in planes at right angles to that of said shaft and carrying gear actuated by said bevel toothed wheel, the spring-actuated bail-lever for returning the key-levers to their normal position, means for insuring the full stroke of each key, and suitable indicating mechanism, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY G. ONEILL.
