Title: Improvements in or relating to sparking plug testing or indicating apparatus for multiple-cylinder internal combustion engines
IPC: F02P17/00
Filed: 1929-01-29
Abstract: 332,895. Mattia, L. L., and Mattia, M. A. Jan. 29, 1929. No Patent granted (Sealing fee not paid). Testing and indicating; external spark-gaps.-Spark-gaps offering larger resistance than the gaps between the plug terminals are placed in shunt with each sparking plug. They may be formed between pointed terminals 16, 19 in radial grooves 15 in a plate of insulating material 10. An apertured plate permits observation of the actual gaps. In a modification arms 83 project from a plate 82 secured to a base plate 81. By means of a crank-handle 109 and eccentric 107 the arms 83 may be adjusted relatively to the terminal 68 connected to the sparking plugs. An arm 85 loosely pivoted about the shaft 56 may be brought with its end in contact with the earthing terminal by rotating the shaft 60 to which is secured a crank 88 having a pin working in a slot 87 in the arm 85. A lead 91 connects the arm to the plate 82. In these circumstances the presence of a spark at any of the gaps 68-83 indicates that the corresponding plug is unable to pass the current. Should, however, defective ignition be due to short circuiting, further rotation of the shaft 60 brings a short arm 126 against a pin 127 projecting from an arm 125 loosely mounted on the shaft 60. A cord fastened to the outer end of the arm 125 encircles the spindle 56 which is thus rotated during the further movement of the shaft 60, and an arm 121 on the spindle 56 moved within a short distance of the terminals 68, passing rapidly round the whole set. The underside of the arm 121 projects into contact with the plate 82 and, through it, is in circuit with the earthing terminal 76. During this second movement of the shaft 60, the arm 85 remains in contact with the terminal 76 since the portions of the slot 87 then engaged is concentric with the shaft.
