Definitions

  • This invention relates to internal combustion engines 5 wherever used, as in motor vehicles and stationary installations.
  • Patent No. 2,075,431 issued to F.M. Du Laney on March 30, 1937 (Cl. 123-148).
  • This patent shows two methods of providing an ignition jumper system, one utilizing an auxiliary dry cell battery, the other providing a low resistance path through only part of the ignition coil.
  • the invention differs from the prior art in that it is universally applicable to all known makes and models 30 of internal combustion engines, including all known makes and forms of storage batteries and ignition coils.
  • the invention also differs from the prior art in that it assures direct contact with the battery terminal (as distinguished from the existing battery terminal clamp or nut) and it assures direct contact with the coil terminal or lead.
  • the invention is also applicable to insulator-enclosed battery terminals which are inaccessible to conventional spring-urged clamps.
  • the present invention does not exclude the concurrent use of conventional jumper cables connected to an auxiliary external power source, e.g., the storage fixturery of another motor vehicle.
  • the jumper cable system herein claimed cannot start the engine with the existing battery alone, it may be used in conjunction with conventional jumper cable means and an auxiliary power supply.
  • the conventional jumper means would operate through and benefit by the claimed jumper cable system, bypassing the ignition circuit elements and resistances which the claimed system bypasses.
  • the object of the present invention is to reduce the resistance between the battery and the ignition coil to a minimum, thereby delivering maximum battery voltage to the coil and, through the coil, to the spark plugs. This object is achieved by excluding from the ignition circuit all unnecessary circuit elements and connections and bypassing all possible resistances.
  • Fig. 1 is a simplified circuit diagram showing the principle of an internal jumper cable system, as herein claimed, incorporated into a conventional ignition circuit for a conventional internal combustion engine.
  • Fig. 2 is a fragmentary perspective view showing one preferred form of the jumper cable herein claimed, connected between a storage battery and an ignition coil, one of the connectors comprising a V-notched contact blade.
  • Fig. 2A is a fragmentary view showing the V-notched contact blade in engagement with the positive terminal of the battery.
  • Fig. 3 is another fragmentary perspective view showing a second preferred form of the invention in which the V-notched contact blade is mounted on a spring-biased clamp.
  • Fig. 4 is a fragmentary perspective view showing the details of the V-notched contact blade as mounted on a spring-biased clamp.
  • Fig. 5 is a fragmentary side view showing the V- notched contact blade held in engagement with the positive terminal of a battery.
  • Fig. 6 is an enlarged fragmentary view, partly broken away and in section, showing the details of a conventional tee tap connector which may be used to connect the claimed jumper cable to the positive terminal of an ignition coil through the lead connected -'to said terminal.
  • Fig. 7 is still another fragmentary perspective view showing a third preferred form of the invention, wherein plug-in connectors are used at both ends of the jumper cable to connect the cable to the positive terminals of a storage battery and ignition coil.
  • simplified, representative ignition circuit 10 for a conventional motor vehicle having an internal combustion engine comprises a storage battery 12 as the power source, an ignition coil 14, a distributor 16, spark plugs 18, and interconnecting conductors.
  • Bypassing the ballast resistor is a fourth conductor 28a which connects the ignition switch to conductor 32.
  • Bypass conductor 28a is in the starting circuit (usually 12 volts) as distinguished from conductor 28 which is in the operating circuit (usually 9 volts) .
  • These elements and the connections among them comprise a series of cumulative electrical resistances which produce a substantial voltage drop in the system and a weakened spark.
  • a bypass circuit 34 in the form of a jumper cable 36 between the positive terminals of the battery and ignition coil.
  • jumper cable 36 is fitted with insulated connectors at both ends, connector 40 for contact with positive terminal 20 of the " battery, and connector 42 for connection with positive terminal 22 of the coil through lead 32.
  • Connector 42 comprises two interconnecting elements, a tee tap element 44 and a plug element 46.
  • Tee tap 44 comprises a plastic body 44a which is adapted to snap around lead 32.
  • the plastic body encases a blade 44b having two bifurcated ends: one end 44c cuts through insulation 32a of lead 32 and makes contact with wire 32b thereof; the other end 44d defines a socket for a blade 46a in plastic body 46b of plug element 46.
  • Blade 46a is connected by crimping 46c or other conventional means to one end of jumper cable 34.
  • connector 42 is not herein claimed per se; it is merely representative of various conventional connectors that may be used to tap lead 32. Referring to Figs.
  • connector 40 comprises a V-notched blade which is connected by crimping 40a or riveting or any other conventional means to jumper cable 34.
  • a plastic body or sleeve 40b on the closed end of the V-notched blade and on the crimping 40a thereof provides suitable electrical insulation as well as a handle for gripping and applying said V-notched blade to the positive terminal 20 of the battery.
  • the manner of applying the blade to the terminal is simply to slide it onto the terminal, either below or above the standard clamp 48, until the edges 40d which define the V-notch 40c securely engage the terminal.
  • V-notch edges are preferrably serrated and that the serrations are capable of scraping corrosion or other oxidized scale or foreign deposit from the surface of the terminal and biting into the terminal, thereby forming and retaining an effective electrical connection therewith.
  • the jumper cable apparatus of Figs. 3, 4 and 5 is similar to that of Figs. 2 and 2A except that the V- notched connector blade is mounted on a spring-biased clamp 50.
  • the handles of the clamp are enclosed in insulating sleeves 52 so there is no need for insulating body or sleeve 40b. As appears in Fig. 4,
  • V-notched blade 40 is attached to one jaw of the spring- biased clamp by means of rivet 54 or other conventional fastening means.
  • the clamp itself forms no part of the jumper cable circuit.
  • the clamp is used as a handle to slide the V-notched blade into secure engagement with the terminal, and it thereafter functions as the means of retaining the V-notched blade in secure engagement with the terminal.
  • the clamp is utilized as the means of disengaging the V-notched blade from the battery terminal.
  • Fig. 7 shows another preferred embodiment of the invention wherein connector elements 60 and 62 are attached to the positive terminals of the battery and ignition coil, and insulated cooperative connector elements 64 and 66 are attached to the ends of jumper cable 68, whereby said jumper cable may be connected or disconnected relative to said terminals by means of said connector elements.
  • connector element 60 comprises a shank 60a having a hole 60b formed therein and a socket formation 60c extending from said shank. As shown in Fig. 7, shank 60a is secured to the positive terminal 70 of battery 72 by the same nut 74 which secures conventional cable 76 to said terminal.
  • Connector element 64 is provided with a tongue which plugs into socket 60c of connector element 60.
  • Connector element 62 corresponds to connector element 60 except for size, and it is secured to positive terminal 80 of the ignition coil by means of the same nut 82 which secures lead 32 to said terminal.
  • Connector element 66 is like connector element 64 except that it corresponds to the dimensions of the socket formation 62a of connector element 62.
  • Connector elements 64 and 66 may be secured to the respective ends of jumper cable 68 by crimping, swaging or other conventional means.
  • the jumper cable may be connected to the battery and coil terminals by simply plugging its connector elements 64 and 66 into connector elements 60 and 62; it may be disconnected from said terminals by simply disconnecting the respective connector elements.
  • V-notched connector 40 may have any functional V-shape which enables it to make and retain good electrical contact with a battery terminal when pushed onto the terminal.
  • the V-shape of the notch accommodates terminals of different diameter, but for the purposes of the claims "V-notch" is intended to include "U-notch”.
  • V-notch is intended to include "U-notch”.
  • its features, including the V-shaped connector are applicable to standard jumper cables.

Abstract

Système de câble de pontage intérieur permettant le démarrage par pontage d'un moteur à combustion interne sans source d'énergie extérieure auxiliaire. Ce système utilise la batterie existante (12) du moteur que l'on fait démarrer en tant que source unique d'énergie pour les circuits de démarrage et d'allumage, mais il ponte tous les éléments et toutes les résistances du circuit possibles dans le système d'allumage au moyen d'un câble de pontage (34) de manière à fournir une quantité maximum d'énergie à la bobine d'allumage (14). Le système s'applique de manière universelle à toutes les marques et à tous les modèles connus de moteurs à combustion interne. Il peut être utilisé, dans des conditions difficiles de démarrage, en combinaison avec un système de pontage conventionnel relié à une source d'énergie extérieure auxiliaire, chaque système augmentant l'énergie de démarrage fournie par l'autre système.
