Application filed June 20, 1925. Serial No. 38,594.
also creates a series of strong current impulses of momentary intensity in the spark lug in order to prevent the weak currents 10m passin throughthe plug. The converter functions in the beginning of every sparking by the coo eration of the large gap and the plurality 0 small gaps in that while between the current impulses which follow during every sparking period the large gap remains ionized so that the high speed interruptions of the converter remains in operation.
It is a further object of this invention to construct a device which will contain the large gap in series with the series of small gaps. A still further object resides in the -specific construction of the electrodes which form the gaps, in that they are constructed.
so as to present convex surfaces between which the gaps are arranged.
Other objects -will be apparent from the following specificatiomta en in connection with the accompanying drawing in which like parts are indicated by the same reference niunerals and in which I Figure 1 is a cross-section of the current converter, havin the large gap. and the small gaps contained therein.
Fig. 2 is a similar view of a preferred form of the invention.
Fig. 3 shows a wiring diagram and a cross-section of a converter inserted therein.
Fig. 4 is a front view of one of the electrodes, and w Fig. 5 is a part sectional view on a greatly enlarged scale showing the construction of the electrode. I
The device can be so arranged that a large gap 1 can be inserted in series in a circuit in which the source of current is indicated at 2, the grounds at 3 and the spark plug at 4. The current converter 5 is here shown as containing a casing 6 of any suitable insulating material in ,which is arranged a plurality of electrodes 7' which are separated by small mica discs. The electrodes in this arrangement form the series of narrow gaps 8 and by means of screws 9 the converter is secured in the circuit as clearlyv shown in Fig. 3.
Figs. 1 and 2 show the large gap enclosed in the casing together with the small gaps, and in Fig. 1 the large gap is indicated at 10 and the small gaps at 11. Fig. 2 shows the preferred form in which a casing 12 of any suit-able insulating material is provided near one end with an annular shoulder 13 against which an electrode 7 is placed and at the other side the large gap electrode 14 is placed. The large gap electrode is thus spaced at its correct distance 26 from the electrode 7 due to the shoulder 15 thereon which abuts against the shoulder 13. In order to fasten the converter on the spark plug a pair of sprin arms 16 are provided integral with the e ectrode 14 which are place. A series of electrodes 7 are arranged in the casing in order to form three gaps 8, the'electrodes being spaced by means of thin discs of mica 18 having a perforation-19 in the center. i A spring 20 forces the electrodes together and the end connection 21 is secured in the casing by means of a pin 22. This end connection is provided with a screw 23 having large threads 24 which is adapted to be secured by rotating the device on a wire, the side 25 of the casing thus forming a tight fit for the wire since it will be forced from the center outwardly, due to the diameter of the screw. This construction thus shows a large gap 26 and a plurality of small gaps, all of which are arranged in series as clearly shown.
The electrode 7 is preferably made of aluminum or any other suitable metal or alloy by stamping and is shaped as shown in Figs. 4 and 5. The surfaces are slightly conyex and are provided with an annular flange 27. This construction is necessary in order to prevent the current, which always rounded surfaces 28 will force the discharge to take place near the center of the electrode, which is approximately through the perforation 19 of the mica disc 18. The distance between the flanges is therefore man times greater than the distance between tie convex surfaces and therefore the electric current will not chip off the edges of the electrodes. The current will jump the gap at 29 for example, and as the mica is gradually decomposed the distance between the electrodes remains unchanged. Mica is used for the discs, since it is but slowly atfected by the heat and sparks of the current and when it decomposes it forms a mass which maintains its non-conductive properties and will also preserve the spaced relation of the electrodes.
The form of the electrode 14 at the sparking point can be sharp, flat or spherical and it can be made of any suitable material.
The construction shown in Fig. 1 can be suitably made by inserting a thick disc of mica in the gap 10 and thin discs at 11, the discs of course having perforations in the center.
