SPECIFICATION forming part of Letters Patent No. 548,79 4, dated October 29, 1895.

Application filed February 4, 1895.

To all whom it rnwy concern.-

Be it known that I, SOLOMON O. IVOOD, a citizen of the United States, residing at WVest Orange, in the county of Essex and State of New Jersey, have invented an Improvement in Counting Apparatus, of which the following is a specification.

Counting devices have been made for indicating the rotations of printing-presses, en gines, cash-registers, 850.; but when the wheel or disk having the tens upon it is turned at the same time that the Wheel or disk is that contains the units more power is consumed in turning the two than in turning the one, and so on the power required to turn three disks or number-wheels is greater than that required for two, and when the thousands number-wheel is turned still greater power is required.

Where the power is given by a machine or by hand there is little difficulty in turning these number-wheels, even where there are four or five of such wheels that are periodically turned together; but in apparatus that is worked electrically difficulty is experienced in obtaining the necessary power from an electromagnet and the required range of movement without the expenditure of a heavy battery power or current.

The present numbering-machine is especially available in connection with an electromagnet for actuating the same, and it is adapted to use in the counting apparatus shown in Patent No. 526,140, granted September 18, 1894, to Henry J. Bang; but the improvement is not necessarily limited to such a counting apparatus.

In the present improvement the units-wheel is turned by a direct application of power, and in its rotation a spring is strained by a grad ual movement, and when the units-wheel is turned from 9 to O the spring is allowed to exert its force to move the tens-wheel one notch, thus distributing the force required to turn the tens-wheel one notch over the entire or nearly entire rotation of the unitswheel, and in like manner the gradual rotation of the tens wheel strains another spring, and when the tens-wheel is turned from 9 to 50 0 the spring is liberated that turns the hundreds-wheel one notch, and so on, thus unify- Serial No. 537,211. (No model.)

ing the power required for actuating the counting apparatus and adapting such counting apparatus especially to an electromagnetic device for giving motion to the counting apparatus.

In the drawings, Figurel is a'plan view with portions of the frame in section. Fig. 2 is an elevation with the side plate removed. Fig. 3 is a section through the number-wheels and their tubular axes. Fig. 4: is an elevation of the central disk and one number-wheel. Fig. 5 is a plan of the pawls and disk, and Fig. 6 is an elevation of one of the number-wheels and the pawl thereon.

The side plates A are connected together by cross bars or columns B, and at O is rep resented an electromagnet with an armature D upon the pivot 01, and the lever or arm E extends to the device that actuates the unitswheel, and there is a spring F to raise the armature D and lever-arm E, and the electric current to the magnet is to be pulsated in any desired manner to actuate such electromagnet, and I remark that while this improvement is especially adapted to an electromagnet as the motor I do not limit myself thereto.

The cross-shaft I is supported in holes or bearings upon the side plates or frames A, and it is provided with a thumb-wheel i, by which such shaft I may be rotated by hand, and upon this shaft I is a tube 6, receiving at its inner end the tens-wheel G, and around this tube 6 is a shorter tube n, carrying at its end the units-wheel H, and separate from but inline with the tube 6 is tube 0, carrying at its inner end the hundreds-wheel K, and around this tube 0 is a tube 0, carrying at its inner end the thousands-wheel L. By this arrangement the number-wheels G H K L are closely-adjacent, and the numbers upon their peripheries are to be in regular order from O to 9.

Upon the tubenis a ratchet-wheel n, which is engaged by an actuating-paw16 upon the lever-arm E, which pawl is advantageously made as a spring, and there is a stop-block 7 on the other side of the lever E, adapted to come down upon the ratchet-teeth n in succession and prevent the inertia from carrying the units-wheel H more than one space ICO at a time, and by this means the units-wheel will be moved around progressively as the electromagnet is energized or the power otherwise applied.

Upon the tube at is a cam 72*, which is in the form of a regular progressive volute, and this cam 7?? acts upon a lever Gr, pivoted upon a rod 8, and having a lever-arm G and actuating-pawl 9, which is adjacent to and acts on the ratchel-wheel 6 upon the tube 6, and upon this lever-arm G is a stop for the ratchetwhe'el e to prevent the same turning too far, and the spring G that is connected to the lever-arm G is strained by the cam 72 acting upon the lever G and raising the same, the spring G being strained as the pawl 9 is lifted preparatory to taking another tooth, and the movement given by the cam n is sufficient to cause the pawl 9 to engage another tooth in the wheel 2 before the lever G is liberated by the end of the cam 12 separating from the same, and when this separation takes place as the units-wheel is turned from 9 to O the spring G acts through the lever G and pawl 9 to turn the ratchet-wheel c and move the tens-wheel one space.

Upon the tube 6 is a cam 9 similar to the cam 12 and this in turn acts progressively upon the lever K, which is pivoted upon a rod 10 and is provided with an arm K with a pawl 11 to engage the ratchet-wheel 0 upon the tube 0 of the hundreds-wheels K, and there is a spring K acted upon by the lever K, which spring is strained by the action of the cam 6 as such cam draws the pawl 11 back to engage another tooth, and when the cam c separates from the lever K and allows the latter to be drawn down by the spring K the ratchet-wheel o is turned and with it the tube 0, and the hundreds-wheel K is moved one space.

Upon the tube 0 there is a cam 0 which acts upon the lever L, pivoted upon a rod 12, and provided with an arm or lever L having a pawl 13, that engages the ratchet-wheel 0" upon the tube 0" of the thousands-wheel L, and the spring L that is connected with the lever L is strained by the cam 0 as such cam draws back the pawl 13, and when the cam 0 clears the lever L the spring L acts upon the lever L and pawl 13, turning the thousands wheel one space. By this arrangement the .number-wheels are turned progressively, and

in the movements of the respective numberwheels the springs are strained gradually by the scroll-cams and furnish the power for turning the successively higher numberwheels when the cams separate from their respective levers, thus distributing the power required in rotating the respective number wheels, so that but little more power is required from the electromagnet or other actuating device at one time than at another time and the movements of the number-wheels are reliable, and each pawl-lever is provided with a stop to prevent the inertia of the ratchet- Wheel and number-wheel causing the parts to turn too far, and there are springs or pawls 14: 15 16 17 to the respe ivc ratchet-wheels e n o r.

In counting devices, especially those adapted to keep tally of barrels, boxes, or other articles passing along an incline or skid, it is desirable to return the counting device to zero after tally has been copied off, so as to start afresh. WVith this object in view the crossshaftI and the thumb-wheel & can be turned to carry with them the number-wheels and bring the ciphers in line, and to effect this a dish or plate u is permanently fastened to the shaft I and is interposed between the tons and hundreds wheels, and the ends of this plate are bent outwardly in opposite directions, as at 18 19, forming fingers or plates closely adjacent to the surfaces of the number-wheels G K, and extending across to the units and thousands wheels H and L, as shown in Figs. 1 and 3, and upon the respective units and thousands wheels are pawls v, that are engaged by the plate to and its fingers 1S and 19. These pawls v are advantageously made of thin metal in the form of curved springs, with the ends beveled, as latches, and the springpawls 12 of the thousands and units wheels are bent, so that the points project between such wheels and the adjacent ones, so as to be engaged by the fingers 18 and 19, respectively, and the pawls for the tens and hundreds wheels may be similarly made or preferably they are upon the plate a, as shown at v, to engage projections 42 on the insides of the tens and hundreds wheels. Hence when the cross-shaft I and the plate u are rotated by the thumb-wheel i and the plates 18 and 19 engage the pawls and turn the number-wheels in the direction of their ordinary rotation such number-wheels are carried around, together with their ratchet-wheels, beneath the respective pawls until all the eipers are brought into line and brought to the place where they are observed through any suitable opening, and there is a spring 75, the end of which is sufiiciently close to the surface of one of the number-wheels to arrest one of the fingers 18 or 19 to prevent the plate a and the crossshaft being rotated by the friction of either of the tubes carrying the number-wheels, but which spring tyields when the shaft is rotated by hand; and it will be observed that the spring-pawls u yield and run under the fingers 18 19 or the projections 71 pass the pawls u when being rotated along with the respective number-wheels, so that such pawls are not arrested by either the plate u or the fingers 18 19 while the number-wheels are being rotated progressively.
