ment in Calculating-Machines, of which the` following is a speciication.

This invention relates to apparatus for use in calculating wages of workmen at given rates per hour or other unit of time, for computing the price of goods by weight or other measure-as, for example, at given rates per pound`-and for similar urposes', the improved apparatus being esigned to exhibit when a suitable key is operated a single amount of wages or price of goods.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a plan of part of the computing apparatus. Fig. 2 is a cross-section as at t e line 2 2 of Fig. 1.- Fig. 3 is a cross-section as at the line 3 3 of Fig. 1. part longitudinal vertical section as at the ine 4 4 of Fig. 3. Fig. 5 is a sectional view of the operating-handle and spindle of the apparatus. Fig. 6 is a longitudinal section thereof and-of part ofthe casing. Figs. 7, 8, and 9 are cross-sections showing various modifications of the apparatus. Fig. 10 is a plan of part of the top of the apparatus as shown adapted for use as a wage-calculator. Fig. 11 is a part longitudinal vertical section of the apparatus, the flaps or shutters being removed. Fig. 11a is asectional detail view hereinafter referred to. Fig. 12 is a crosssection as at the line 12 12, Fig. 11. Fig. 13 is a cross-section showing one of the flaps or shutters and relative parts. Fig. 14 is a cross-sectional view as taken at the line 14 14, Fig. 11, showing means for preventing overwinding of the rollers after the materia carried by`same has been fully unwound. Figs. l5 and 16 are somewhat similar views to Figs. 12 and 13, respectively, of another modiiication, but differ in that the operatingle'vers are replaced by plungers.

As represented at Figs. 1 to 6, the improved apparatus comprises a long rectanguar of rollers B B carrying a band C of suitable fabric wound partly on each, the band having rows of figures printed or otherwise impressed thereon representing summation of weekly wages at given rates per hour or the` price at given rates of given weights of goods.

Fig. 4 is a or other casing A, in which is fitted a pairl For example, at one endy of each row the and on the same horizontal line are exhibited in succession the prices for that weight of goods at one, two, three, four,&c., pence or shillings per unit of weight. A glazed slit D in the casing exposes onl a single row of price-iigures along with t e weight of the goods, which -is seen through a smaller opening D but such price-figures are concealed by shutters or flaps E, of which one is provided for each price-figure, the said shutter being carried or formed on lever-arms E and operated by finger-keys F to uncover a single price-figure at a time. 1

A keyboard resembling that of a typewriting machine is provided, the keys being preferably in the form of plungers F', passing down through orifices in the top of the casing A and being for convenience arranged in double rows. One key is provided for each shutter or flap E, covering a price-figure, and each key-plunger F is pivoted at its lower end to a corresponding pivoted lever-arm E', which is normally maintained in the position indicated at Fig. 2 by means of a spring E2, having one end secured to a stationary bar E3 and the other to a snug on the arm E. By depressing the key and plunger F F the corresponding lever-arm E is rocked on its pivot e and the shuftter or flap E drawn back to expose the price-iigure under it on the band C. The depression of the lever-arm E brings a catch e thereon under a pawl e2, extending the length ofthe casing and actuated by a spring e3, and the lever-arm is thereby held down. If another key be pressed down, the correspondin lever-arm Eis depressed and the catch e t ereon in clearing the pawl e2 prior to being en aged presses it aside, and

By this means when any key is acted on to expose a fresh figure on the band O the figure previously exposed is immediately covered up, so that one summation only is exhibited at a time. l p

In order that the weight-figure may be exhibited prior to operating the keys to expose a summation-iigure and that the said weightfigure may not' be involuntarily changed, a special key f and plunger f are provided to Fig.' 3. The plunger f when depressed forces down against the action of a s ring g a lever G, which by contact with a pm h on a weight in pounds or other unit is engravedl thereby releases t e catch e of the firstmentioned lever-arm, which thereupon r1ses. A

IOO

actuate a locking device, as represented at IIO lIO

divided lever H H de resses a series of spring-actuated catches Vwhich normally engage the teeth of a gear-wheel I on the spindle of the operating-handle J On the end of a lever 'G a catch g is formed to engage with the pawl e2 and retain said lever in its depressed position. The catch g on the lever G by displacing the pawl e2 in clearing it frees from engagement with the pawl any one of the plungers'F and lever-arms E which may for the time being be depressed, so that on changing from one rate-figure to another the summation-figures are all covered.

When the key f has been depressed and the gear-wheel I unlocked, the handle J may be turned round to bring into view through the glazed opening D any weight-figure or timefigure of the row on the band C, as also to bring the corresponding summation-figures under the flaps E. A key F may now be depressed to expose the desired summation, and its action on the pawl e2 serves to release the locking-key f, which thereupon rises.

In order to insure that the band C may be kept taut, the drums B B are driven by gearing, as shown at Fig. 3, the gear-wheel I eing in mesh with a pinion K on the axle of the drum B, while a gear-Wheel I (shown at' Fig. 6) drives the pinion K on the drum-axle B through an intermediate gear-wheel I2. To compensate for variations of diameter in transferring the band from one drum to the other, the coiling and uncoiling of a spring L is used, said sprin bein preferably fitted within the handle whic, as shown at Fig. 6, is made up oftwo disks, one end of the spring being secured to one disk and the other end to the other disk.

One disk J is fast on the spindle j, von which the gear-Wheel I is keyed, and the other, J is on a sleeve j', on which is fitted the gear- Wheel I', and While the gear-Wheels I and I are arranged to drive the drums B B at equal speed inequality of s eed of Winding and unwinding of the han is compensated for by the spring yielding or ,taking up slack.

- To revent overwinding of the drums, y a Worm on the spindle j is itted to gear with a Worm-wheel M', carrying arm N, which on full winding in one directionstrikes a sto N', and in the other direction the end o the worm M brings the drums to rest.

In thel modification shown' at Fig. 7 the ilaps E and lever-arms E are made in the form of bell-cranks, to which the plungers F are pivoted, and notches f are formed in the latter with which engage pawls e', which are coupled together, as shown, so that When one key F is depressed that previously engaged is released and forced up to its normal position by'a spring e4.

In thel modification represented at Fig. 8 the flaps E are in the form of sliding plates whose ends are engaged by pivoted bellcranks E', connected to the key-plungers F.

In this case the pivoted pawl e2 is adapted to engage a catch-piece e3 on the plate E, which is drawn back to uncover a summation-ligure by the action of depressing a key, and on a second key being depressed the catch e3 on the late E thereby actuated by tilting the paw e2 releases the plate E previously withdrawn.

In the example shown at Fig. 9 the keys F are replaced by hooked ends on sliding coverplates E, which are pulled down by hand against the action of springs et. ing pawl devices are similar to those shown at Fig. 8. l Y

Figs. 10 to 14illustrate a modified construction of the apparatus as shown adapted for wage-calculating purposes. The card O under the glazed slit 1n Figs. 10 and 13 is marked with figures representing in shillings the rate per Week of fifty-four hours. The band C on the rollers B B is figured with the amounts earned at corresponding rates for the total of hours for which wages are payable.

As an example of the operation of the apparatus and as show'n at Fig.` 10, seventy-one and one-half hours have been chosen as at the total number of hours for which Wages are payable, the rate selected being forty shillings per week. The total wage, 252/1135, is given on the band C on withdrawing the corresponding flap or shutter E. The flaps or shutters E are in this case formed integral with the arms E and keys or finger-levers F, which are pivoted at e and held inthe normal position by springs e4; A spring-actuated pawl e2 is provided to engage with catches e3 on the levers E', and, as in the examples already described, the depression of any one key acts to release the previously-depressed key-lever from engagement with the pawl. The form of locking device used in this modiication in order to exhibit the hour-figure prior to operating the keys to expose a summation-figure and that the said hour `or weight figure may not be involuntarily changed consists of a linger-lever f, pivoted at f 2 and having an arm 3, attached at j'4 to a sliding plate I-I, adapte on depression ofthe iinger-leverf to engage with a series of springactuated catches h', which normally engage the teeth of the gear-wheel I on the spind e of the operating-handle J. On the lever f 1s a catch g to engage with the pawl e" and retain said lever in its depressed position. The catch g by displacing the pawl e2 in clearing it frees from engagement with the pawl any one of the iinger-levers F and lever-arms E which may for the time being be de ressed, so that on changing from one ratee to The engag- IOO IIO

another the summation-figures are al cov- 12 5 ered.

When the key f has been depressed and the gear-Wheel I unlocked, the handle J may be turned round to bring into view through the glazed opening D any hour-figure or weight- 13o figure, as the case may be, of the row on the` band C, as also to bring the corresponding summation-figures under the fla s or shutters E. On depression of a key' to expose a desired summation it, through its action on the awl e2, serves to release the'locking-key f, W -ch, thereupon rises.

The gear-wheels I I are arranged to drive the drums B B through pinions K K the wheel I being fast on the spindle j of the handle J, while the wheel I is loosely mounted on said spindle. To compensate for variations of diameter in transferring the band from one drum to the other, the spring L is, as shown particularly at Fig. 11, located between the gear-wheels I I but may be placed at any other convenient part of the mechanism connecting the drums.

To prevent overwinding of the rollers, apparatus such as is represented at Figsll and 14 may be used, and comprises spring-actuated pivoted levers L, the roller of either being adapted, as shown, to engage with the slot l in the roller B or B when the band C has been fully unwound from either roller, a catch Z on each lever also engaging with either of two ratchet-wheels l2 (having teeth arranged in opposite directions to each other) on the spindle j'of the handle J, so that further rotation in an unwinding direction is prevented. l

The mechanism illustratedat Figs. 16 and 17 is somewhat similar to that shown at Figs. 12 and 13, respectively, but differs therefrom in that the finger-keys and forked plungers F F and f f replace the finger-levers F and f, Figs. 12 and 13.

Having now described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. Calculating or computing apparatus comprising a casing having fitted within it rotatable drums carrying a band on which are rows of figures any of which may be eX- posed through a slit in the casing, a series of movable fiaps or shutters normally covering the figure on the band, and a series of keys so connected to said iaps or shutters that when one is depressed and locked to Withdraw a shutter and expose a figure the others are freed to cover the remaining figures so that only one summation is exposed at each action.

2. In calculating or computing apparatus the combination with a casing having fitted therein drums carrying a band showing rate and summation figures, a slit in said casing for viewing the figures on said band, a series of flaps normally interposed to cover said figures manually-operated keys for withdrawing any of said flaps, and interconnecting deviccs whereby any single Hap when opened to expose a figure is retained and the others of the flaps'released and closed as described.

3. "In calculating or computing apparatus the combination with a casing and drums carrying a figured band of flaps covering said band, spring-actuated locking devices for holding the drum and manually-operated means for releasing the drum as described.

4. In a calculating or computing apparatus the combination with a casing of a pair of drums carrying a band and arranged so that either drum unwinds said band from the other of said drums, a handle comprising two parts connected by a spring, and ear-wheels serving to positively operate one rum and to operate the other of said drums through the intervention of said spring, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of .two subscribing witnesses.
