for ch the apparatus has been regulated. Th automatically restores the current at t 1e end of one or several minutes and comprises an induction coil the plunger core of which is kept outside the coil by a spring the tension of which can be regulated according to the maximum intensity of the electric current authorized for the plant in question, and a pole piece intended to close or an-ea; the circuit of an automatic time Enh .Eljjidl' of known type placed in such a position with regard to the plunger core that it may be attracted by the latter, when in its position at the end of its movement under i action.
The accompanying drawings show a constrncticnai form of the invention, by way of example.
l is a front view of the apparatus.

,1 o gives separately and viewed from the interrupter device.
-fl is aplan view of the pole piece p. 3 is an axial section of the apparatus given in Fig 1.
Fig. 6 is a side elevation.
Fig. 7 shows in side elevation a known constructional form of automatic time interrupter combined with the apparatus shown in Figs. 1 to 6.
Fig. 8 is a diagram showing the main and shunt circuits and the clock-work mechanism for restoring the circuit conventionally.
In the form of construction shown, the apparatus comprises a coil a (Fig. I) wound with a thick short insulated wire, in series with the circuit to be controlled.
This coil a is wound around the lower part of a tube Z) (Fig. 1). In this tube Z) a soft iron plunger (Fig. can move Serial No. 431,214.
freely. This plunger 0 is hung on a chain cl running on a grooved pulley e. The axis of this pulley revolves directly at one end in the frame f (Fig. 2) and, at the other end in the axis 70 of the movable dial g. The movable dial g revolves on its axis is (Fig. in the wall of an upright of the-frame It is maintained inside the frame by the pin it. A flat spring 2' supported between the frame and the dial 9, prevents the latter from turning too freely. A spiral spring (Fig. 2) is fixed at one end to the axis k and at the other to the pulley 6 (Fig. 2) so that in turning the dial 9, the spring 7' is more or less set which spring acts by torsion on the pulley e. A similar spring j, fixed on the other side of the pulley e, is secured at the other end in the frame 7 and serves to counterbalance by torsion, the weight of the chain (Z and of the plunger 0.
In turning the dial 9 by hand the tension of the spiral spring j is decreased or increased. This tension acting by the agency of the pulley c and of the chain d on the plunger 0 keeps it with more or less force in the top part of the tube b, passing beyond the coil a Fig. The dial 9 bears indications corresponding to the intensity to be allowed in the plant. As soon as this permitted intensity is exceeded by addition of supplemental lamps or apparatus the magnetic field developed in the coil a is sufficient to cause descent of the plunger 0 as far as the centre of the coil a where it is stopped by an insulating plug m Fig. 5. IVhe-n the current is cut off, the plunger 0 being no longer subjected to the influence of the magnetic field of the coil a, is sharply drawn out of the coil by the tension of the spring j as far as the stop plate 01..
The tube 7) at its exit from the coil (4 is provided with a transverse opening 0 Fig. 5, through which a soft iron pole piece 7) (Fig. 4) can pass. The pole piece p is fixed to the end of a rod Q (Fig. 1) secured at the other end on the axis 1', by aid of screw 3. The axis 1 turns between the two uprights of the frame 7.
The stop piece t 5) limiting the travel of the rod in stopping its part passing beyond the axis a", keeps the pole piece 7) at a specified distance from the opening 0 of the tube 1). There is a metal ferrule 10 on the rod A ring made of insulating material separates this ferrule u from the rod g. The plunger 0 reaching the centre of the coil a is at its maximum magnetization. This magnetization is then sufficient to attract the pole piece p. WV hen the pole piece 12 is attracted by the plunger 0, the rod 9 -follows its movement by the agency of the aXis r revolving in the frame This movement has for eflect to engage the ring to betweenthe two contacts c Fig. 3, which thereby are connected. The two contacts c are fixed on a block of insulating material 11) (Fig. 8). On this block 10 the stop plate a is also fixed, its object being to pr vent the plunger coming out 01 the tube 6 under the influence or the spring j.
The insulated metal ring a of the rod g connecting the two contacts 1) puts into circuit an electromagnet a in a shunt circuit 5 the object of which is to cut off the total current of the plant by breaking the main circuit at c and then restore it automatically in a given time by means of a clockwork mechanism or any other slowing down system shown conventionally in Fig. 8.
7 represents, as an example, an automatic time interrupter of known type comprising an electromagnet with clockwork mechanism restoring the current after a moments interruption.
in Fig. 1 :0 is an interrupter by aid of which the apparatus can be put into circuit or out of circuit and y indicates the current entrance and exit terminals.
The whole device described is enclosed in a box, which may be locked, not shown in the drawings.
T he interrupter a; is intended for use when required to temporarily allow a greater intensity of current than that for which the plant is regulated.
