- TIME METER Filed may 22, 1931 s Sheets-Sheet 2 1 N VEN TOR. (o/7s fan 7 fiaffegay A TTORNEY.
- My invention has for its object a time meter chiefly for telephonic conversations.
- a meter working at least partly elec- 6 tll'akally and combined if desired with a printing 'It consists chiefly on one hand in the electric control of the time indicating part of the meter through its connection with a time distributor and on the other in disposing between the meter itself and this time indicating part a clutch which is controlled either mechanically or electrically from a distance.
- Fig. 1 is a front view of a time meter executed according to my invention, the dial being removed.
- Fig. 2 is a cross section of the same time meter.
- Fig. 3 is a wiring diagram for use with the time meter in combination with a printing clock.
- Fig. 4 shows'hand operated means for controlling certain of the circuits shown as electrically controlled in the preceding figures.
- Fig. 5 is'a vertical section through the structure of Figure 4, the section being taken on the line 5-5 of Figure 4 and the shaft being shown in elevation.
- the time meter is carried between a bottom plate 1 of iron and a front plate 2.
- the electromagnet 3 drives the time keepin part of the meter. To this end, its armature 5 is provided with a driving catch 9 engaging, when the electromagnet 3 is excited, the ratchet wheel 10 canied by the shaft 11. A pinion 12 rotating integrally with the ratchet wheel 10 is held stationary by the detent 13.
- the second electromagnet 4 serves to control the clutch or carrier controlling the movable part of the meter.
- Thismovable part is carried by the pivot 8 and moves integrally with the armature 6 of the electromagnet 4.
- the clutch or carrier comprises two-armed levers 14 and 15 between which the main shaft 16 of the meter and the transmission shaft 1'1 may rock.
- a transmission wheel 21 is keyed to the overhung part of this shaft which, when the clutch is in,
- the wheel 19 isadaptedtomeshwiththepinionflofthe clockwork. Round the hub 22 of the wheel 19 is. wound a return spring 23 the free end of which is secured to the lever 15. I
- the wheel 19 carries a stop 24 which for the inoperative position of the wheel is urged against the stop 24a on the lever 14 by the spring 23.
- the wheel 19 carries also four pins 25, 26, 2'7 and 28 adapted to engage in succession the shoe 29 carried by a spring contact blade 30 with the interposition of insulating material. When the spring blade'is raised it comes into contact with the cooperating contact 31, insulated with reference to the casing. 7
- the carrier comprising levers 14 and 15, carries an insulating cleat 32 which, when in its in-. operative position, moves the contact strip 33 away from the contact 34 which, together with the strip 33, is mounted on the casing of the device. 7
- the hand 18 moves over a dial 35 divided into say twelve minutes and protected by a glass pane.
- the connections are provided by means of contact pins 36 engaging sockets not shown.
- the connections are illustrated in Fig. 3, assuming the time meter works in combination with a printing clock.
- the electromagnet 3 is provided with a single windin whereas the electr c-magnet 4 carries two, one 37 for attracting its armature and the other 38 for 35 keeping it attracted, one terminal common to both windings being permanently in electric connection with one terminal of a storage battery, the positive terminal for instance.
- the contact spring 30 To the same pole is connected the. contact spring 30 whereas the contact 31 is connected through a lamp 39 to the negative pole.
- the other end of the winding .38 is connected with the contact 33.
- the distance control of the time meter is ensured through a key 40 adapted to enter three different positions, of whichtwo 41 and 42 are stable and the third 43 is not stable.
- the position 42 is that of inoper'ativeness.
- the key closes two contacts 44 and 45.
- the former 44 closes the connection between one end of the electromagnet winding 3 and the negative pole ofthe battery whereas the other end of the electromagnet winding is connected with a time distribution system illustrated diagrammatically by the contact 46 periodically closed over the positive pole by a masterclock.
- a time distributing system is a system whereby timed the contact 44 now open.
- the clutch electro-- inbringingthekeyminto its ve position 41 where it remains in stable Pig. 3 shows the connections corre to this position.
- the time controlling 3 is energized each time the contact 46. i. e.,
- cmtrolling et 4 The latter attracts itaarmaturedwhichraises at the same time-the carrier and the parts carried thereby.
- the attendant stopsthemeterbyreturningthekeyminto its inoperative position 42 where it remains in stable oonditim. This causes the time-indicating part olthemetertostopworkingtheoircuitotthe electro-magnet 3 being energized through magnet remains however energized owing to its armature-retaining or maintaining coil 38.
- the on wheel 21 disengages the pinion 12 and the wheel 19. under the action oiitsspring23,returnsintoitsoriginalangular position with the stops 24 and 24a in engagement.
- the shoe 29 can-- not prevent the e 0! the studs 25-25-47 or 28 as the levers 14 and 15 and parts carried thereby are lowered together with the armature 6 of the electromagnet 4 whereby the path or these studs is brought well below this shoe.
- Figures 4 and 5 show a modification oi the meter allowing the clutch to be controlled by hand.
- the electromagnet 4 is omitted and so is the key 40. and the control is provided by a lever 49 secured to a shaft 50 pivotally borne by the front plate of the meter.
- the cam 51 may raise the levers l4 and 15 by engaging the lever 15. For this position of the movable part, the transmission'wheel 21 meshes with the pinion 12 and the gearwork oi the meter is driven by the clockwork.
- the lever 49 may occupy three distinct positions, the left hand position corresponding to inoperativeness, the middle position and the right hand position or operative position. For this last position the two cams are operative whereas oniy cam 51 is operativeior the mean posi- .tion and neither cam is operative for the lefthand position.
- my invention may be used for measuring other durations than the duration of telephone conversations.
- the clockwork may be also different from the device disclosed; in particular this clockwork may be constituted by a small synchronous motor fed with alternating current from the mains.
