WILLIAM P. QUENTELL, OF NEW YORK, N. Y.

ADDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 756,706, dated April 5, 1904.

Application filed December 22, 1903. Serial No. 186,212- (No model.)

To aZZ whom it may concern.-

Be it known that'I, WILLIAM P. QUENTELL, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Adding-Machines, of which the following is a specification.

This invention relates to adding-machines; and the invention resides in novel features of construction set forth in the following specification and claims and illustrate din the annexed drawings, in which Figure 1 is a plan view of a machine embodying this invention. Fig 2 is a section along m m, Fig. 1. Fig. 3 is an inverted plan view of Fig. 1. Fig. 1 is a section alongyy, Fig. 5 shows a form of stylus. Fig. 6 is a plan View of a portion of a disk-on a larger scale than the preceding figures. Fig. 7 is a section along 2 2, Fig. 6. Fig. 8 is a section along a .2, Fig. 6.

The machine comprises a number-disk a, which carries numbers up to any desired denomination. have been found to be a practical arrangement. A frame or support is shown at Z). This support can be of any suitable shape or construction, such as box or open-work. A plate, as

shown in the drawings, will answer. The buttons or legs 0 for the supporting-plate when made of rubber will not be apt to slip when the device is manipulated. This frame 5 has a sight-opening at d, through which one or another of the figures of disk (0 is exposed as the latter rotates. The pivot e of the rotary disk is supported by a strip or bridge-piece f. The

opening 9 in the frame I) has lip or part g, forming a zero-stop, as presently explained. The disk is partly exposed through this opening g. The disk has a perforation or seat at h for the insertion of a stylus or like instrument, Fig. 5, by which the disk can be rotated or set to Zero. When the stylus is arrested by stop g, the figure 0 shows at sight d. About the circumferential portion of disk a are holes or catches i. The frame or support has a slot at is. This slot is shown running along or exposing a number of said holes a. The holes shown are a cheap construction;

The figures from O to 99 but other means, such as corrugations or shoulders or other catch portions for a stylus to take hold, can be employed.

Guides m are shown leading into slot 10. These guides/might be called branch slots of the trunk or main slot is. These guides are shown numbered from 1 to 9. For spacing and convenience of selection the oddnumbered guides can be placed on one side of the slot and the even numbers on the op posite side. The guide numbered 9, for example, is at such distance from the stopping-point of the slotthat is, the end of the slot just past guide 1 -that when a stylus or the like is inserted into the hole 71 at such guide 9 and the disk is rotated, as shown by the arrow, by moving the stylus to rotate the disk until the stylus is stopped at such stopping end of the slot such disk has advanced nine numbersthat is, the number now showing through the sight d is nine higher than the number last preceding at the sight. Similarly by starting at another guide, as 8 or 5, the disk is rotated or advanced a corresponding number in each case.

The stylus can be a rod of metal or a pencil, or other instruments might be made to answer.

The guides-m are of such size or enlarged at their ends that the stylus can be readily inserted therein and then run along to slot is to engage into the required seat or hole 2'. As these holes are small and close together, mistakes are liable to occur when inserting the stylus into these holes direct; but errors can be easily avoided by previously inserting the stylus in a guide.

In addition to guides k the disk may have guides or grooves 0 branching from holes a, so that a stylus will be guidedboth by guide m and by groove or channel-guide 0 to enter the required one of the holes 2'. The guides or grooves 0 are readily formed by depressions in the top or face of the disk, giving the under side or face of the disk a wavy or corrugated appearance. The sheet metal forming the disk is sufliciently thin or flexible to allow this deflection or corrugation.

The under side of disk 64 is held from bending or supported at an edge portion by a plate 01, having an offset or portion which while allowing the entry of the stylus into a hole a certain distance at the same time suitably limits such insertions.

A stop or under plate 7) at perforation it limits the entry of the stylus at this point, so that when rotating the disk to the zero-stop the stylus cannot project and strike the bridge f, whereby mistakes or'premature stoppage might be caused.

A counter is shown at q in form of a hand pointing to a series of figures or a dial-say 0 to 7. 1n the example shown this counter is a lmndreds-counter. If, for example, the disk should show a figure, say S0, at the sight (Z and the hand q point to 2, a total of 280 would be thus indicated.

The hand 9 is connected to a gear or segment 1' by pivot s, which is a shoulder-screw. A spring 25 gives a friction to prevent accidental shift or rotation of the hand. A pin a connects the hand and gear, so that they swing together. This pin a projects into a slot in plate 5, whereby its movement or swing can be limited between certain points-for example, O and 7 in the example shown. In moving its figure 99 along past sight (Z plate a by tooth 4; moves gear w one step to set the hand (1 along one figure. WVhen the disk a is set to zero, the tooth e is in such position that the gear 1' can be moved back to Zero, which is done by the operator moving hand 9 to zero.

' Suppose three columns of figures are to be added up. The first or right-hand column or units are first added by successively inserting the stylus into the guides respectively corresponding to the successive figures in the column and rotating the disk the required or corresponding extent by moving the stylus each time to the lower terminal of the slot. If such first or unit column should add up to 103, the hundreds-counter stands at 1 and the disk shows the figure 3 at sight (Z. The figure 3 is then noted or put down by pencil or the like with a memorandum of ten to carry. The disk and counter are then both set to zero. To the next column is then first added the amount carried, say ten, which is made to appear at sight (Z by moving plate a by successively actuating from guide 9 and guide 1. Then the figures in said next column are successively noted. Suppose the total of the second column is a8. Such sum will now appear at sight (Z. Putting down the 8 leaves four to carry to the third column. The parts a and g are then again set to zero. Noting the next or third column of figures plus four, or the amount earriedgiving, for example, 56 the grand total will be a 5683.

A stylus 11 is shown with a cap or pencil engaging part to be adaptedfor application to a pencil; but the invention is not limited to any special form of stylus.
