Most of the apparatus of the above kind are provided with code controller discs having a cer tain number of teeth which are grouped together and which cooperate with electric contacts. 10 Such apparatus require the use of discs having a relatively large diameter in view of the fact that the discs should be provided along their pe riphery with the number of teeth which is neces to each other. The moving member has no in?uence upon the transmission of impulses except on a portion of its pro?le and this portion may vary. The length of this portion is determined-by the posi tion of a. feeler which cooperates with a code 10 member. Use is made preferably as a moving member of a rotating member effecting a complete rev olution for each of the digits of the number which is to be formed. sary for producing generally at least six or seven 15 series of ten impulses, separated by hollows cor However, use may be made of a moving mem responding to the periods of rest. In order to avoid the above drawback it has ber having a profile consisting of several identi cal shapes, of which one complete shape is used been proposed among others to use apparatus capable of transmitting a large series of impulses of which a few only are really transmitted by 20 means of code controller discs which short-cir cuit certain impulses in order to compose the de sired series. In these devices, the members which emit the for each digit which is to be formed. In this case the moving member will effect for each digit a fraction only of a revolution. The moving member may be a cylinder, or a cam, etc. It may form an element independent of the make and break device acting upon the contacts of im pulses or it may act itself as a make and break 25 device. An alternating motion or an oscillating motion may be imparted to the feeler. The latter is dis '_ impulses and those which effect the short-cir cuits must operate in perfect agreement with each other. As however, one revolution of the code controller disc corresponds to about a hun dred revolutions of the transmitting member, the code controller discs should be made with great precision, and this can be obtained with di?iculty only in the practice; their manufacture and ‘more particularly their ?tting makes them very placed towards the code members which may be costly and fragile. The code members may be arranged on a plate or on a ring or they may be distributed in groups upon several ?ttings. The latter may be ?xed either parts of a circle or sectors, or rectilineal toothed members or cam members and may act 0 along their height and not along their length, as was hitherto the case. , The present invention does away with the above drawbacks and allows of obtaining a device for transmitting impulses which has smaller di~ or they may be displaced by saccades underneath mensions, whilst reducing to a large extent the the feeler. ' ~ precision required in the manufacture. In order to make the invention well under The apparatus for transmitting impulses ac stood, an example of its carrying into effect 40 cording to the present invention is characterized will be given hereinafter, which is more particu— in that the formation of the impulses, trans larly applicable to the automatic telephone sys mitted by any suitable device, is- in?uenced by terns. a movable member having a pro?le or outline, Figs. 1 to 4 relate to an impulse transmitter the motion of the movable member being such that after a pro?le has acted to form a series for predetermined calls. of impulses, the movable member is placed again the axis of an impulse transmitter comprising in a position similar to that at the beginning, for the formation of a new series of impulses. a rotating member having the shape of a cylin der and acting also as a make and break device The moving member'is constructed so as to have a pro?le consisting of one shape or of several identical shapes, the length of each shape being such as to correspond for a given speed to the duration of ten impulses followed by a cer 55 tain period of rest. ‘ Figure 1 is a horizontal section made along with contacts of impulses. . Figure 2 is a vertical section made along the line X—-X of Figure 1. Figure 3 is a development of the rotating cyl ' inder. ‘ 55 2 2,107,988 Figure 4 is a section along the plane Z-Z of Figure 3. Figure 5 shows , movable member having a pro?le with two identical shapes. Figures 1 to 4 show an impulse transmitter in which the movable member consists of a rotat ing cylinder acting as a make and break device coacting with contacts of impulses. The said movable member effects a complete revolution for each ?gure of the number to be formed. 5|] are maintained inside supports 8| which are integral with the outer cylinder I. Impulse con tacts 52 and 53 are mounted on a support 54 (Fig. 2) which is integral with the member 29. The device is completed by a speed regulator and by starting and stopping means, not shown in‘ the drawings. The apparatus works as follows: When a number is to connected, the corre sponding name marked on the cylinder I is 1O The apparatus comprises a cylinder I adapted brought opposite the pointer 4 by rotating the to rotate around its axis and on which are placed _ cylinder. This rotation brings the correspond the names corresponding to predetermined num ing code-member 50 within reach of the feeler 49. The cylinder l rotates When the cylinder I has occupied the desired 15 between a rear plate 2 and a front plate 3, the hers of telephone calls. position, a pressure is exerted on the handle I6, which has for its effect to tension the spring latter being provided with a pointer 4 opposite which may be brought any of the names marked along the generating lines of the cylinder I. Between the plates 2 and 3 is ?tted, along the 20 axis of the apparatus. a shaft 5 which carries toothed wheels 6 and 1 which gear respectively with other toothed wheels 8 and 9, the wheel 8 being secured upon an intermediary shaft l0 whilst the wheel 8 is integral with a sleeve H capable of rotating freely around the shaft ID. The wheel 8 is integral with a ratchet wheel l2 coacting with a pawl l3 which is integral with a box l4 containing a spring l5 secured on the one hand to the box and on the other hand to 30 the shaft l0. At the end of the shaft I0 is ar ranged a, handle [6 adapted to place the spring l5 under tension. On the other hand, the sleeve 1 l adapted to rotate freely around the shaft [0 is integral with a toothed wheel I‘! gearing with another toothed wheel I 8 mounted at the end of a sleeve l9 adapt ed to rotate freely around the shaft 5 and integral with a movable member 20 having the shape of a cylinder and provided at its periphery with ten 40 teeth 2| made of an insulating material and an gularly displaced relatively to each other and spaced by intervals 22 (see Fig. 3). A portion 23 without teeth connects the tenth tooth to the ?rst tooth. The cylinder 20 comprises also a path 25 hav 45 ing a certain number of horizontal portions 2‘ connected with each other by means of inclined planes 21 (Fig. 3). The path 25 acts as a guide to an arm 28 carried by a member 29 adapted 50 to slide along an axis 30 secured to the rear plate 2. The member 29 is connected by means of arms 3| to a sliding block 32 which may be displaced along an axis 33 parallel to theaxis 20 and also mounted on the rear plate 2. The 55 member 29 and the sliding block 32 are subjected to the action of springs 34 and 35. Along the arms 3| are adapted to slide two supporting members 36 made integral with one another by means of a connecting piece 31 en gaging between the arms ll of a double fork 22 (see Fig. 2) of which the other end is provided with arms 40 coacting with a projection 41 in tegral with a sleeve 42 mounted on a fixed shaft 43. The sleeve 42, and therefore the projection 4|, are capable of an angular displacement around the shaft 41, due to the action of an arm 44, the end 45_ of which bears against a cam 48 mounted on the shaft 5. The said cam has a certain number of straight portions 41 con 70 nected with each other by means of inclined planes» 48. One of the supporting members 24 carries a feeler 49 coacting with code members ‘I having the shape of toothed blades arranged around 75 the movable member 2|. The said oode members l5. Whilst the pressure is exerted, the pawl l3 slides on the ratchet wheel 12. When the handle 16 has been released, the spring l5 which expands, carries with it the box [4 in a move 20 ment of rotation and the pawl I3 presses the ratchet wheel [2 and the toothed wheel 8 which is integral with it, thus causing a motion of the toothed wheel 6 and consequently of the shaft 5 and cam 46. On the other hand, the toothed wheel 1 causes a rotation of the cylinder 20 which may be made of an insulating material, through the inter mediary of the toothed wheels 9, l1 and II. The rotation of the cylinder or movable member 20 30 has for its effect to free the arm 28 which at rest is situated upon the highest portion of the path 25. Under the effect of. the springs 34 and 35 the feeler 49 rests against the ?rst tooth of the code-member chosen. The height of the teeth 35 of the code members 50 is such that the feeler 49 allows the impulse contacts 52 and 53 to be in?uenced only by a given number of teeth of the movable member 20 corresponding to the num ber which‘is to be formed. As soon as the teeth 40. of the movable member act upon the impulse con tacts, the arm 26 rests_ upon the path 25 and follows the horizontal portions 28 and the in clined portions 21 of the path until it is brought back to the starting position. 45 Whilst the movable member 20 has e?ected a complete revolution, the cam 46 has been dis placed through a fraction of a revolution only. The end 45 of thevarm 44 has followed the hori zontal portion 41 and the inclined plane 48 and 50 is brought to the next horizontal portion. The displacement of the arm 44 acts through the projection 4| .upon the fork 30 which displaces the supports II by sliding them along the arms il. The feeler 49 comes thus opposite the next tooth of the code member ‘I and the device‘ works in a similar manner for the next revolu tions of the movable member 24. It is obvious that the modes of construction shown in the accompanying drawing have been given only by way of example. Concerning more particularly the movable member which effects a complete stroke for each digit to be formed, it is clear that use may be made of other devices, for instance of a rack or other member having an alternating motion. On the other hand. it is powble by means of a few small modi?cations, to interchange the movable members shown by way of example in 70 the mode of construction, or even to make them rotate in a direction opposite to that shown in the drawingifthespacecomprisedbetweentne first and the last horisontal portion has made inclined. . 3 2,107,988 What I claim is: 1.
