Application filed November 28, 1913. Serial No. 803,587.

To all whomit may concern Be it, known that I, EUGENE GASSMANN, a citizen of Germany, and a resident of the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Distributers for Electrical Ignition Systems for Internal-Combustion Engines, of which the following is a full, clear, and exact specification. 1

This invention relates to electrical ignition systems for internal combustion engines, and consists of the herein shown and described improvement in the construction of distributers which constitute an essential part of such ignition devices employed for multi-cylindrical engines. It is well known that the ignitiondevices for such engines are employed on automobiles, trucks, and other similar vehicles, and are almost continually exposed to atmospheric conditions, dampness and' rain; it is also well known, that if moisture or water penetrate into the electrical connections, or in the contacts, short circuiting of the'apparatus and breakdowns of the engine result. Many attempts were made, indifferent ways, to water proof the connections, etc., but theobstacle v to success of these attempts was always found in the connections of the electrical conduits, entering fromthe outside into the distributing device, and which were thus exposed, 0r rendered accessible to dampness, rain, etc.

The object of my invention is to arrange the parts of the distributer, and to provide means for connecting its parts with their respective conduits, whereby this source of danger is entirely avoided.

In the accompanying drawing a distributer, constructed according to my invention, is shown Figure 1 being a front elevation; Fig. 2, a longitudinal sectional view thereof, on lines 22 indicated in Fig. 1, some parts being shown in elevation to aid in a clearer representation of the device; Fig. 3 is a view similar to Fig. 2, showing the arrangement of the connection from the collector brush to the distributer contact.

The operative parts of the distributer are located in the casing a. The rotating disk 0 is secured to the driven cog-wheel b, rotatably mounted on shaft d, and driven by cogwheel I), set on the armature of the magneto, whereon also the collector ring e is fixed. The contact segments for effecting intermittent electrical connections between the central brush f and the brushes 9, g, 9 etc., are aflixed to the disk 0, and the brushes 9, g, 9 etc., as well as the central brush 7, and the collector brush it, are mounted in the cover a of the distributer casing. Brushes f and g, g, 9 etc, must be electrically connected with the metallic cores q of cables 0, 0, 0 0 etc, and to effect their connections to be safely protected from atmospheric influence, dampness, etc., I make the cover a of the distributer casing of substantial thickness, and arrange the connections within, in the manner shown, and hereinafter described. For this purpose the interiorly screw-threaded recesses i are made in the ,cover, in the points where the brushes are to be located. The tubular metallic lin ings 7c, screw-threaded exteriorly and interiorly, are screwed into these interiorly screw-threaded recesses 2'. These tubular metallic linings 7c are closed at their inner ends and transversely perforated at p to admit the metallic cores of the cables. The interior termini of the linings 7c are concaved, and conically pointed screws 1' are screwed in, to clamp the cores of the cables to obtain a close contact of the metallic cores 9 with the linings 7c and safely permanent connections. Metallic springs Z are then set in the tubular linings is against the heads of the screws 7", and then the brushes 9, g, g-,etc.,are inserted against the springs Z, which then serve to yieldingly press the brushes against the distributer disk 0, and to hold them in close contact with the distributer segments.

Radial bores 25 are drilled frompoints on the periphery of the cover a of the distributer casing, one to each of the terminals of the recesses z, in which the brushes 9, g, 9 etc, are set. The radial bores are made just sufiiciently large to admit the insulations of cables 0, 0, 0 etc., which are then snugly fitting therein, and the bared ends of the cable cores are electrically connected by screws 0* to the tubular metallic linings 7c, in which the brushes 9, g, 9 etc., are set as hereinbefore explained.

The collector brush it is set in a similarly the radial recess 71 in the base of the cover a. The lining is is connected by the metallic strip u to the lining if, an intermediate device, connected by the cable m with the central brush. f in the same way as explained with reference to the brushes 9, g, 9 etc. The intermediate device k and its connection, the metallic strip u while convenient and desirable, are not essential, and the connection of the collector brush it with the brush f may be made directly, by extending the cable m to the metallic lining is of the collector brush.

The radial bores tare preferably made to fit snugly upon the exterior insulations o, 0, 0 etc., of the cables, but their ends may also be closed air tightly with cement. This prevents moisture, or oil penetrating into the connections of the metallic cores 9 of the cables with the linings k, and as the cover a is tightly fitted upon the distributer casing, no part of the metallic connections, or of the apparatus, is exposed, and the danger of dampness, or rain, or oil penetrating into the connections, or into any part of the apparatus, is safely avoided.

I claim as my invention:

1. A connector for electrical conductors, comprising a casing of insulating material, having a recess and a bore communicating therewith; a metallic lining, perforated in line with the bore in the casing, set in the recess; means for securing an electrical conductor inserted in the metallic lining through the bore in the casing, in electrical contact therewith, and an electrical contact set in, and electrically connected with, the metallic lining; substantially as herein shown and described.

2. A connectonfor an electrical contact and an electrical conduit, comprising a casing of insulating material having an interiorly screw-threaded recess and a bore from its periphery to the recess, a tubular exteriorly screw-threaded metallic lining set in the recess; an insulated cable snugly fitted into the bore, and means for securing it therein and in electrical contact with the metallic lining; a carbon brush and means for yieldingly supporting it therein, set in the lining and electrically connected therewith; substantially as herein shown and described.

3. A distributer casing, having interiorly screw-threaded recesses and radial bores running parallel to the exterior surface of the casing from its periphery to the termini of the recesses; a tubular, exteriorly screwthreaded metallic linings set in the recesses; carbon brushes set in the linings and means for pressing the brushes in contact with the distributer disk; insulated cables, snugly fitted into the bores, and means for securing the cables therein and in electrical contact with the metallic linings; substantially as herein shown and described.
