REGISTERING DEVICE Fgled June 28, 1937 lnvenio 's Patented Apr. 23, 1940 UNITED STATES PATENT OFFICE assignors to Societe veloppement DIndustries Mecaniques Auxiliaire pour le De- D. I. M.), a corporation of Switzerland Application June 28, In France 4 Claims.
This invention relates to computing or registering machines.
It is the object of the present invention to provide an improved registering device which is characterized by its extreme simplicity, the certainty of its operation, and the very small number of strong and simple parts of which it is composed. A meritorious feature of the invention is the novel manner of returning the machine to zero by a simple backward turn of the register shaft.
The following specification and accompanying drawing represent one embodiment of the invention. It is understood that the principle of the invention is applicable to other forms of registering machines.
Various other objects, advantages and meritorious features will appear more fully from the following specification, appended claims, and accompanying drawing, wherein:

The spring 2 has a bent end engaged in notch 4 of a'disc 5 fixed upon the shaft l by a key engaged in the groove 6 of this shaft.
1937, Serial No. 150,818
July 4, 1936 The device whose movements it is desired to count is connected to the first drum of the register by any suitable means, such as a worm gear.
In the embodiment of the invention shown in Fig. 1, the movement is transmitted to the regis- 5 ter by a gear wheel I mounted for free rotation on the hollow shaft 8, which is slidably fitted over shaft I and keyed thereto for joint rotation therewith. A one way drive mechanism couples the gear wheel I to the first drum on the shaft. 10 As shown in Fig. 4, it comprises cooperating crown ratchet bosses on the gear wheel and'a sleeve H fixed to the first drum, the teeth 9 and H) of which are shaped to provide a one-way drive between the gear wheel and the drum.
The calculating machine has as many drums mounted in succeeding order as necessary. Each drum, except the first, is provided on one face with a ratchet wheel I3 (Fig. 2) having ten teeth, for example, and on its oppositeface (Fig. 20 3) with a hub l4 and a boss l5 on the inner side of its rim. Means for connecting two drums together for joint rotation comprises a spring support IS on the hub 14, the two elements being secured to the drum by a screw I1. Spring support l6 carries a flexible metal blade l8 bent at its extremity Hi, this metal blade being of a width sufficient to rest a part of its elbow 20 on the boss 15, its middle part will climb the'incline of the cam 2i interposed between two adjacent drums and its other side will extend into the plane of the ratchet wheel so that as it nears the end of its passage over this cam it will enter in engagement with the teeth on the ratchet wheel of the next succeeding drum and cause its rotation as will be explained more fully hereinafter. The boss l5 on which rests the elbow 20 of the flexible metal blade 16, is for the purpose of avoiding contact of the spring with the inner surface of the rim of the next drum. 40
The cams 2| (Figs. 5, 6, and 7 are formed of thin plates, such as steel for example. They are interposed between the drums, and have a contour like that shown between the points A and A. These cams, identical in form and dimension, are positioned in the embodiment of the invention illustrated herein by the rod 22 and their support on the base 3. They are provided as shown with straight bottom edges bearing on the flat top surface of the base 3. They are mounted on the rod 22 for bodily movement lengthwise thereof and follow any axial shifting movement of the drums during the operation of the device. The engagement between the straight bottom edges of the plates and the base portion prevent the plates from turning on the rod or following the rotative movement of the drums.
Several steel washers 23 (Fig. 1) furnished with keys engaged in grooves 6 of the axle l are interposed between the registering drums.
The springs 24 and 25 compressed between the end Walls of the machine and the opposite ends of the drum series cause a certain frictional cohesion of the drums and the washers 23. The springs also yieldingly force the drum assembly and the gear wheel 1 toward one another and operatively engage the teeth 9 and ID of the drive mechanism. If the gear wheel I should be rotated in the direction opposite to the direction in which it drives the drums the teeth 9 will ride out of the teeth l0 and either 01 both the drum assembly and the gear wheel will retract back against the springs 24 and 25 to accomplish the disengagement. The operation of the registering device is as follows:
At first, when all the drums are at zero, the springs occupy the position shown in Figs. 5 and 8, that is to say, the elbows 20 of the flexible blades rest on the boss l5 and the bent extremity of the springs are adjacent to the edge 28 at the point A on cam 2|.
Movements which it is desired to count are transmitted to the toothed wheel I to rotate the latter in any suitable way. The teeth 9 associated with the wheel 1 engage with the teeth ID on sleeve H and impart rotation to the first drum l2. The teeth 9 and H) are shaped so that rotation of the wheel I in a counting or adding direction is transmitted to the first drum of the series but reverse rotation of the wheel 1 is ineffective upon the drums.
The first drum in turning causes the numbers 1, 2, 3, 4 to appear successively on the dial corresponding to this drum. At a certain moment, the elbow 20 of the metal blade of the spring [6 encounters the cam 2| at the point A (Figs. 6 and 9). The spring then commences to climb the incline of the cam 2|. When it occupies the position shown in Fig. 7 (and in the front view in Fig. 10), that is to say, when it is exactly in vertical alignment with the axis of the drum, the numeral 9 of the dial of the first drum appears in view. The bent extremity IQ of the spring then comes into contact with the radial side of one of the ratchet teeth of the next drum (Fig. '7) and will carry the same just past the point A of the slope at which time the extremity I 9 returns to the boss l5- after an exact turn at 36. It will then retract from the ratchet teeth with which it has just made a tenth of a rotation, that is to say, the distance of one tooth, which causes the number 1 to appear on the dial of the second drum at the moment when the first drum reaches Zero. The washers 23 which are keyed in the groove 6 of the shaft I, are immovable during the operation of the registering device, and frictionally act to prevent the rotation of one drum from being transmitted to the next succeeding drum. Each of the drums are thus isolated and are not able to be turned except by action on its ratchet wheel by the flexible blade of the preceding drum. The first drum then commences a new turn about the shaft I which upon completion will cause the second drum to rotate one tenth of a revolution or the distance of one tooth. This will cause the numeral 2 to appear on the dial, and so on.
Each complete turn of the second drum corresponds to ten turns of the first drum, and each complete turn of the third drum corresponds to ten turns of the second drum or to one hundred turns of the first drum, and so forth.
Return of the registering wheels to zero is effected by turning the hollow shaft 8 and its associated shaft I in the direction opposite to their operating or computing direction of rotation. This will be in a clockwise direction as viewed in Figs. 5 to 7 and will at the same time rotate backwardly the friction washers 23 and the drums l2 compressed into frictional engagement therewith. The drums will thus be rotated in a direction reverse to their normal counting direction of rotation.
Each drum is separately prevented from further reverse rotation as soon as the bent extremity I9 of the flexible blades encounter the stop 26 on the high side of the cam plates 2|. When all the drums have returned to this position, all the zeros of the graduations will appear on the dial. Then the hollow shaft 8 is freed from control. The bent end of the spring 2, fixed on the support, returns into a notch 4 of the disc 5 which is keyed to shaft I. This will yieidingly hold the shaft in such position during the computing operations of the drums.
The collars 21 and 28 (Fig. 1) are for the purpose of preventing longitudinal displacement of the shaft I during operation.
If movements are transmitted to the registering device in the opposite or subtractive direction, these movements will not be registered because the teeth 9 of wheel I, if turned in a reverse direction, will not impart movement to the teeth H1 and as a result the drums are not rotated.
