To all whom it may concern:

Be it known that I, RICHARD Ktjcrr, a sub;

ject c t-the German Emperor, and resident of Heniru-on the=Main, Germany,- have invented certain new and useful Improvements in Connection with Shunt-Circuit 'filting' Devices for Mercury-Vapor Lamps, of which the" following is a specificartio Certain types of mercury vapor lumps are started eye shunt magnet which sets inmotion an armature connected-with thelamp so Sir to give tothe lfamp the tilting motion required for starting it. When, in consequence of the are established by this tilting motion, the main current passes through the lamp,- u switch electromagnetically operated by the said main current, opens the shunt circuit, the shunt magnet is deener'giued and the lamp returns to its normal position. Oh the main current being cut off from the lamp, the said switch is again closed. If for any reason the main current should failto' pass through the lamp, the shunt remains switched in and the lamp remains in the" tilted position. The tilting back and therepetition of the tilting motion only hitherto been capable of being doneby' switching: in v end out by hand.

While, with direct currentleinps, only one .tilting motion is required, when the lamps .sre operated by alternating current, failures in starting the lamps mustbe expected and this renders an automatic repetition of the tilting motion desirable.

invention provides a device which effects-an automatic repetition of the tilting motion until the lamp becomes lighted, by which device the interruption o-fthe shunt circuit is not alone caused electromagneticaHy by the flow of the main current, but

the up and down'motion of the tilting mechanism isutilized to open the shunt circuit a'fthe end .of the upward motion, and to close it again at the end of the downward motion.

According to this invention there is provided, in addition to the switch electromagnetically; operated by the main current, a

second switch which is in series with the first switch and is-ineluded in the shunt circuit which is opened and closed by the tilting mechanism.

One of thejvh'rbis forms in which the invention mu'y be embodied is illustrated diagrammatically by Figures 1 and 2 of the accompany'i'ng drawing.

Fig. 1 shows the whole arrangement at the instant when the tilting motion has been effected without the lighting of the lamp having taken place and before the lamp commences to return to its normal position. Fig. 2 shows the device back In normal position with no current passing through the lamp between the main electrodes. The him is on the point of being again tilted by t "e shunt magnet to the position shown in Fig. 1.

:When the lamp is in the initial or normal position shown in Fig.- 2, with ut current ipuss'mg through the lamp froxngene main :electrode to the other, current car! new from the binding post at the left of the 1am for example, through'the closed switch the shunt magnet, and the switch S to the binding post at the right hand of the lamp, energizing the shunt magnet, which lifts the armature N, to the position shown in Fig. 1. This upward movement of the armature 'N. tilts the lamp B to the position shown in Fig. 1. The switch S which is illustra-ted as a; mercury switch, hes bsniiafignru the upward movement of the armature'N, of the shunt magnet into the open circuit position by the rod S which 15 rigidly conmeted with the shunt armature N, The switch S to'be o erated by the main current has remained closed, because the main current failed to pass through the lamp.- 0 ening of the shunt circuitby the action 0 the armature N on the switch S permits the lamp to return to its normal position, the rod S (Fig. 2) returns the switch- S to the closed circuit position and the tilting motion 'is repeated. If the main current come into action and pass through the lamp between the main electrodes the switch S is energized by the flow of the main current through the lamp and switches out the shunt current electromagnetically and the lamp returns automatically to' its normal position.

The mechanism may be varied in its de tails, and the switches S and 8,, can be combined in one and can be switched in and out electro-magnetically by the main current, or mechanically by the tilting mechanism.

I claim:
