- HIGH TENSION D15 SYSTEMS OF INTE Filed Patented Mar. 13, 1934 PATENT OFFICE HIGH TENSION DISTRIBUTOR FOR THE IGNITION SYSTEMS OF INTERNAL COM- BUSTION ENGINES Gottlieb Steiner, Solothurn, Switzerland, assignor to Switzerland Scintilla Aktiengesellschaft,

Application November 18, 1931, Serial No. 575,979 In Germany November 22, 1930 3 Claims.

This invention relates to high tension distributors for the ignition systems of internal combustion engines. In distributors of this kind as hitherto known the distributor segments are I moulded in the distributor body made of insulating material.- Such designs have the disadvantages that the whole high tension distributor has to be replaced after the ends of the distributor segments have been used up under the influence of the high tension current passing from these segments unto the electrodes in the distributor blocks. Apart from this, the segments are moulded under pressure into the insulating material of this distributor, thereby being deformed to a certain extent making the condition of the insulating material worse.

According to the present invention, these disadvantages are overcome by the distributor segment being arranged interchangeably on the outside of the distributor body and the distributor body, made of insulating material, being moulded by itself without any metal segments inside.

Referring to the drawing Fig. 1 is a vertical section through the high a tension distributor device, and

Fig. 2 a vertical section turned through 90 with respect to Fig. 1.

Fig. 3 is a plan view of the distributor.

The preferred form of the device is the only an embodiment of the invention illustrated and will now be described in detail, but without implication of limitation beyond the scope of the invention as set forth in the claims.

a is the distributor body made of insulating :5 material, 12 the fastening flange of same for fixing the distributor body on the large distributor gear, not shown in the drawing, and c is a boss arranged in the axis d--e at the end of the body a. 1 represents the distributor segment mounted on the outside of the distributor body. Fig. 1 shows how the end g of this segment is fixed to the fastening flange b by means of the screw it and the insert 1' the latter being cast integrally with the distributor body. Fig. 2 shows in the same way the other end of the distributor segment which is turned through 90 with regard to the end g of the segment; it is fixed to the support I of the distributor body by means of the screw h and the insert 1, the latter being again cast into the insulating material. The boss c of the distributor body has an opening m (see Fig. 1) and an opening n (see Fig. 2) in which the distributor segment is guided thereby preventing the same from turning. To the distributor segment I is riveted a metal bushing o in the axial hole of which the high tension carbon brush is housed; the carbon brush is not shown on the drawing. Said carbon brush transmits the high tension current to the distributor segment 7; the current passes across the air gap p (see Fig. l) and after the distributor has turned through 90, across the air gap 11 (see Fig. 2) to the electrodes 1* and s respectively.

After the ends g and is of the distributor segment have been used up under the influence of the high tension current, the distributor segment ,1 can be taken oif by loosening both screws h and the old segment can now be replaced by a new one, but the distributor body itself can be used over again. On the other hand it is quite clear that an insulating body moulded by itself without any metal strips inside will give the best guarantee for an excellent insulating quality.

What I claim is:

1. In a high tension distributor for magneto electric ignition systems of internal combustion engines the combination of a distributor body of conical shape, having at one end a fastening flange for fixing the distributor body to the large distributor gear, a distributor segment of same shape as the distributor body in its vertical sec tion, fixing means for said distributor segment and metal inserts for said fixing means cast into the insulating material of said distributor body.

2. In a high tension distributor body for magneto electric ignition systems of internal combustion engines the combination of a distributor body of conical shape having at one end a fastening flange for fixing the distributor body to the large distributor gear, a distributor segment of same shape as the distributor body in its vertical section, one end of said distributor segment being fixed to said fastening flange of the distributor, the other end being fixed to an arm of the distributor body situated remote from said fastening flange, both ends bent aproximately 90 from the main portion, fixing screws for said distributor segment and fixing inserts for said fixing screws cast into the insulating material of said distributor body.

3. In a high tension distributor body for magneto electric ignition systems of internal combustion engines the combination of a distributor body of conical shape having at one end a fastening flange for fixing the distributor body to the large distributor gear, a distributor segment of same shape as the distributor body in its vertical section, one end of said distributor segment being fixed to said fastening flange of the distributor, the other end being fixed to an arm of the disbut located in its axis having two slots for guiding the distributor segments, thereby preventing the latter from turning and having a central hole to house a metal bushing, which is fixed to the distributor segment, this bushing containing the high tension carbon brush.

GOTTLIEB STEINER.
