This invention relates to a remote control for short circuiting spark plugs and means for cating troubles within internal combustion engines of the type equipped. with spark plugs and 5 used on automobiles, air-planes, tractors, marine engines, and the like.

The objects of the invention are to provide a trouble detector for internal combustion engines.

I accomplish the objects of my invention as 10 shown in the accompanying drawings which form a part of this specification and in which similar letters of reference refer to similar parts throughout the various views.

Referring to the drawings, Figure 1 is descriptive of the device and shows the hook up.

Figure 2 shows a sectional end view on the righthand unit shown in Figure 3, and of that portion of my device which in use is normally placed beneath the hood of an automobile or elsewhere. Figure 3 shows a sectional side view of that portion of my device shown in Figure 2, two units only being shown, it being understood that any required number may be had. Figure 4 shows a partial plan View of the'switch with which my device is equipped for the purposes of remote control. In use this switch is conveniently positioned at the steering wheel, or elsewhere. Figure 5 shows a sectional end View of said switch. Fig. 6 is a top plan view of the magnet.

Referring again to Figure 1, T shows the battery used for ignition. M shows a spark coil. N shows the distributor, and-S the spark plugs. These parts are all common on internal combustion engines with which my device is intended for use. My device can be made for any number of cylinders, but for illustration I use only two of the complete circuits, showing one in open position and one in closed position, open position meaning that the device is not in working position, and closed position meaning that my device is in working position. The wire B connects battery T with contact points B which are a part of the gang switch, this connection to the battery being connected on the same pole as the spark coil and distributor. I another contact point of the switch, is not in contact with B while in open position therefore no current can pass through the switch. I is connected by means of the wire I to the coil I thus completing one side of the circuit to the coil I The other side of the circuit follows wire C direct to the other side of the plurality of coils including the coil I and at a point designated 5 by K a wire C is connected to the. wire 0 and wire C is connected'on the other end tothe permanent magnet G of the horse-shoe type and through the bearingsto the swing arm G which has a tail piece G which is acted upon by an electromagnet, the operation of which is controlled by the. switch I (detail of the electromagnet explained later). It will be understood that the permanent magnet G functions when the unit is in any position by returning the arm G and its tail piece G to its normal open position shown in the left unitof Figure 3 when the current is disconnected. The object of this arm G is explained in the next circuit which is similar to the one just explained, except that it is shown in closed position. When the device is in open position, the operation of the spark plugs S is not interfered with. In the closed position wire B connects the battery T. with a contact point B as explained previously. In this circuit, the switch is closed and contact point I is electrically connected to contact point B thus allowing the current to flow through wire I to coil I, through the coil I-to wire C and back to the battery T. This causes the electromagnetto attract the tail piece G (see also Figure 3-) and rotate the same in the bearings G and G towards the magnetized core. H (Figure 3). G being affixed to G Figures 1 and 3, and pivoted on the same arm, will swing up into contact with D in the position as shown by G, see also Figures 1 and 3.

The operation is as follows: When the switch 133 and I? is open, current flows fromthebattery through the primary winding of the ignition coil M and back to the battery. 7 Flow of current through the primary winding of the ignition coil M induces a high tension current in the secondary winding of the ignition coil M, which normally, or when the switches B I and D G are open, flows from the coil M through the distributor N, wires S spark plugs S, to ground on the engine and so back to the coil which is grounded. When a switch B I is closed and its coil I is energized to operate the armature G to close the electromagnet switch D G the spark plug is shorted out and the high tension or spark plug current flows from the coil M through the distributor wires S wire F, switch D' (3: wire C wire 0' back to coil M.

In the open position first above explained, it will be noted that arm G does not come in contact with contact point D and therefore wire F has no effect on the spark plugs S All the circuits in my device act in a similar manner, and any number of spark plugs may be likewise short circuited by closing the switch which is on the line with said spark plugs. When dual ignition is used, contact with the two points D, Figure 2, is made simultaneously, so that an electrical connection may be made to each spark plug.

Figures 2, 3, 4, and 5, show more particularly the details of my device which embodies two parts, a switch box, and a unit box. The unit boX which carries the main mechanism or parts comprises the casing A, Figure 2, which has two exterior binding posts B and C, from which wires B and C connect my unit with the battery, wire B corresponding to B on the wiring diagram, which correspondence applies to wire C and other parts similarly designated. From the binding post B a wire B (not shown in the wiring diagram) conveys the current to plate B Figures 4 and 5, on the switch. The plate B acts as one of the contact points of my switch and is so designed that one of a series of finger projections thereon projects under each-button n the series of buttons. When the button 15 pressed, the respective finger thereunder contacts with another contact in the switch. The buttons designated as B and B Figure 5, operate the two sections shown. Button 38 shown in Figure 5, when pressed, forces a finger projection on plate B against a contact point I which is part of plate 1 and said plate, through wire I is electrically connected to the coil 1, Figures 1 and 2. This closes the circuit, allowing the current to flow through the coil I to the wire C Figures 1 and -2, which connects with the binding post C, through wire C in Figure 3, and thence back to the battery by means of wire C Figures 1 and '2. The current passing through the coil I causes the core H which is within the insulated spool'I-I to become magnetized, which attracts the tail piece G (see Figure 3') and forces the arm G, Figures 2 and 3, into contact with D. Wire C coming from the battery as heretofore explained, is always in contact with the artificial permanent magnet G within which is one of the pivot bearings for G and G and these parts being of electrically conductive materials, when arm G contacts with D, the electric current passes from D to the :battery, through the arm G to the bearing block in G", through the wire C back 'to the battery "T as heretofore explained. The current travels from the spark plugs S, through the wire F, Figures '1 and 2, to the binding post E Figure 2, and D is the contact part of said binding "post, Figures -1 and 2.

The coils I and '1 are optionally made with an inner winding, designated by "the character I Thecore H comprises strips of wire, passing through the center of spool I-l. Any one of the coils I, with the corresponding core H when electrically connected with a source of energy, constitutes 'and functions "as 'an electric magnet. G designates the second 'pivot ,point for the arm G. The arm G and tail piece G in Figure '3, are operated the same .as arm G and finger "G in Figure 2. The switch button B5, Figure 5, is shown not pressed in this case, and therefore the :circuit is open. I .Figures 1 and 5, .show the contact point with which plate B would register if pressure was applied to the button B Contact point 1 Figures land 5, is attached 5 plate 1 Figure 5, and is electrically connected to 15, Figures 1 and :3, by means of the wire 1 Figures 1 and 3. The other end of the coil is connected to the binding post c, Figure 3, by:

the wire C thence to the battery by wire C Figures 1 and 2. D, Figures 1 and 3, shows the contact with which the arm G registers when current flows through the coil I. This coil I and wire C Figures 1 and 3, are electrically connected at K, Figures 1 and 2. 0*, Figure 3, shows a wire which extends the full length of my unit, and with this wire, connections are made similar to that made by P, Figure 3. I, Figure 3, shows a conduit used to shield the wires between switch and the other portion of my device. E and E Figure 3, show binding posts to which the wires F and F Figures 1 and 2, are connected, the said wires being also connected to the spark plugs. There are two contacts D, Figure 2, shown and two binding posts E to allow connection to a cylinder in which dual ignition is "used. When single ignition is used, only one of these binding posts and contact points are required. J shows the casing of my switch, Figures 4 and 5. The number of buttons on the switch should correspond to the number of the coilsor pairs of binding posts designated by the characters E and E Figure 3.- L, in Figure 3, shows :a hanger means by which my unit may be suspended in convenient position while in use, a similar hanging means on the opposite end of my device is provided.
