SPECIFICATION forming part of Letters Patent No. 672,185, dated April 16, 190l. Application filed March 8, 1900. berial No. 7,914. (No model.)

To all whom, it may concern:

Be it known that I, ISAAC S. DEMENT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Counters, of which the following is a specification.

This invention relates to improvements in counters such as are used in connection with registers or other devices to count and indicate the number of times a certain operation has been performed.

My invention relates particularly to the improved construction of the mechanism for enabling accumulation of the count from each wheel to the next higher wheel of the counter, and the invention also comprises improvements in the resetting means.

The improved counter comprises, in connection with the actuator or count and a series of numeral-Wheels, connecting or accumulating devices between the successive wheels normally inoperative, but brought into operation in a definite position of the preceding members of the counter to cause the counting motion of such preceding members to be transmitted to the next higher member. In connection with such normally inoperative connections between the several numeral-wheels the invention comprises resetting means consisting of parts which are in engagement with the numeral-wheels and are normally disengaged from one another, so as to enable free relative movement of the wheels in counting, but are capable of being brought into engagement with one another and with a resetting device to enable resetting of the numeral-wheels.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is an end view of a counter embodying my invention, partly broken away to show an interior part. Fig. 2 is a side elevation of same. Fig. 3 is a section on the line A A in Fig. 2 looking toward the left. Fig. 4 is a section on the line A A in Fig. 2 looking toward the right. Fig. 5 is a longitudinal section of the counter on the line B B in Fig. 1. Fig. 6 is a detail sectional view of portions of two numeral-wheels, the actuating device, and the connecting mechanism on the line 6 6, Fig. 3.

The mechanism of the counter is supported in a. suitable frame ct, carrying a shaft or spindle b, on which the several numeralwheels 0 c c c are supported in such manner as to be free to move rotatively, but are restrained froin longitudinal movement, sleeves d d d (1 being interposed between the spindle b and the several 11 umeral-wheels, as hereinafter described. Each numeral-wheel c c, &c., is provided on its periphery with a series of facets numbered from 0 to 9 and with notches e between said facets engaging with wedgesf on leaf-springs f, which hold the respective numeral-wheels in exact angular position and prevent accidental displacement. The digits on the respective facets of the numeral-wheel appear through a suitable opening in the inclosing case (indicated at g in Fig. 3) in the usual manner when in register with said hole, so as to give a sight-reading of the amount indicated by the counter.

At one end of the series of numeral-wheels is the count or actuator h, here represented as a disk rotatably mounted on the spindle b and provided with an arm 77., the vibrations or strokes of which are to be counted. This arm may be connected to a register or to any other device the number of Whose operations is to be counted. Surrounding the disk It is a disk i, also loosely mounted in the spindle b and having a peripheral laterally-projecting tlange t", with an opening at 11 where the arm h projects through, this opening being suflioiently wide to permit the said arm to have a certain amount of lost motion or free relative rotative movement within said opening. A leaf-spring 70, hearing on the periphery of disk t, opposes a slight frictional resistance to the rotative movement of the said disk i, so that as the actuator-arm h is moved in one direction or the other it does not begin to move the disk 1) until the said arm strikes the end of the slot or opening 2 The disk '1; is held in place longitudinally by a collarj, interposed between it and the first or units wheel 0. The rotating movement of the disk t' may be limited by a pin 2' thereon engaging in a slot in the frame a.

A notch 77. in the disk 71 engages with one arm Z of a bent lever pivoted at Z to a lug m, extending inwardly from flange t", the other arm I? of said lever having a nose, pin, or pawl 77, extending toward the units-wheel and adapted when pressed toward the units-wheel to engage in any one of a series of ten pockets or catch-depressions 0 in the side of said wheel. One of these depressions has a centralholep, extending clear through the units numeral'wheel, and in this hole slides a pin q, provided with a rounded head (1, which occupies a countersink r in the opposite side of the numeral-wheel and is adapted when the said pin is pressed toward the tens-wheel c to engage in one of a series of ten depressions in the side of said tens-wheel. Similarly the tens-wheel has a sliding pin (1 in one of its depressions provided with a rounded head adapted to engage the hundreds-wheel, and so on for the successive wheels until the last wheel in the case a is reached, this last wheel having only the pockets 2) without any sliding pin. The totallength of each pin (1, with its head q, is just equal to the thickness of the corresponding numeral-wheel, so that each pin-head when pushed fully in is completely within the wheel, and the wheels are thus free of one another, and the heads and de pressions being rounded it is apparent that any relative movement of the wheels will tend to push the heads inward and release the wheels from one another unless the corresponding pin is held from endwise movement. It is preferable, however, to make the forward faces of the depressions in the unitswheel straight, as shown in Fig. 6, so as to enable the lever pin or pawl n to more easily retain its engagement therewith.

The resetting mechanism comprises the sleeves d d d d aforesaid, the last of which carries a head or flange s, by which it may be turned. The adjacent ends or faces of these sleeves have corresponding ratchetshaped teeth 3 and depressions s inclined on one face and abrupt on the other, so that any movement of the main resetting-sleeve d in the direction for resetting will carry the others with it. Each sleeve d d, &c., carries a pin t, engaging in a slot or slit it, extending longitudinally through the corresponding numeral-wheel, so that the rotation of any one of the said sleeves causes rotation of the cor responding numerabwheel, while longitudinal movement of the sleeve relatively to the wheel is permitted.

The operation of the counter is as follows: Each movement of the count or arm h in the direction of the arrow in Figs. 1 and 4: will first, by the engagement of notch lbs with the lever-arm lyengage the pawl n of said lever in that one of the depressions in the unitswheel which is for the time being opposite said pawl, the lost motion or limited amount of free relative movement between the arm 7t and the disk ilenabling such operation of the pawl-lever H n to be effected before the arm h, by striking the end of slot 4?, causes the disk 6, with the pawl-lever and the actuator, to turn as a whole in the further rotation of the actuator. In such further rotation the units-wheel will participate on account of waist the engagement of the pawl n in a depression 0 of said wheel, and the units-wheel will thereby be advanced one notch. In the return movement of the actuator h 72, the first effect will be to withdraw the pawl 11 from the units-wheel, and then the actuator, together with the disk 2' and the leverZZ' n, carried thereby, will move back to the initial position. Successive operations of the actuator will produce similar progressive movements of the units-wheel, without, however, affecting the other numeral-wheels until the numeral 9 on the units-wheel comes into register, at which time the accumulating or connecting pin (1 in the units-wheel comes opposite the pawl 92, when the actuator is retracted. Then 011 the nextstroke ol the actuator the lateral movement of the pin or pawl n will drive the pin q end wise and cause its head q to project from the other side of the unitswheel and engage in the depression in the tenswheel that happens to be opposite it, thus locking the tens and the units wheels together, so that the completion of the actuators stroke will cause progression of both units and tens wheels one step. On the retracting movement of the actuator the pawl 12v is disengaged, before, and in its next stroke it strikes the depression next to the one with a pin and leaves the pin free, so that as the units-wheel is turned and movement of the tens-wheel is resisted by its snap-springf the pin is forced back to its original position by the engagement of its rounded head with the rounded depression, leaving the wheels free, as before. Each wheel thus accumulates from the next lower wheel in similar manner, the highest wheel of course needing no connecting-pin.

To reset the counter, the resetting-head s is turned in the direction ot the arrow in Figs 1 and t and the head is pressed gently inward at the same time, so as to cause engagement of the toothed and notched endsof the sleeves (Z (Z d d. The sleeve (i will then successively gathefl the several sleeves d d (Z and the connected numeral-wheels c c c, and as the numeral-wheel e is always in direct rotative connection with the sleeve (1 it follows that after a certain rotative movement of the head s the nu moral-wheels will all be in connection with the said head and they will all be brought to rest at a zero-reading through the right opening, it being understood that the several pins /,on the respective sleeves are so arranged with respect to the teeth or notches on said sleeves that when all the nu moral-wheels are caught or gathered, as described, they will all present the same numerals through the register-opening.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

1. In a counter, the combination with an actuating device and a plurality of numeral wheels, of means for actuating each wheel accumulatively from the preceding wheels and from the actuating device, consisting of a IIO pawl device carried by the actuator and operating the first numeral-Wheel, and connecting means carried by succeeding numeralwheels, normally in disengaged relation, but adapted, by engagement with the said pawl device and with one another, to be brought into engagement with the next higher wheel.
