Various other objects of the present invention will be apparent from the following description taken in connection with the accompanying drawings wherein:Y
Fig. l is a vsomewhat diagrammatic View showing a device of the invention in the environment in which it will-normally be employed: r
Fig; 2 is an enlarged View of the control device showing the control unit in longitudinal section; i
Fig. 3, is a view of part ofan engine circuit showing in 'schematic form the deviceof .the present invention connected in vthe circuit.. l v f Referring to. Fig. 1,'the `automobile mechanic M is shown at'the front end of a truck which has the hood H raisedntov -facilitate work on the engine. The automobile mechanic vM is shown in the processof testing the engine ,withthe aid of-a device of the present invention. In one hand, the mechanic holds thecontrolunit `11 of such device, ,the; devce'ineluding a leadassembly 13 extending from the control unit to the electrical circuits of the engine.
Referring to Fig. 2, the unit 11 includes a tubular housing 15 closed at its opposite ends by elastomer inserts 17 and 19. The lead assembly 13 includes three leads 21, 23 and 25 which extend through a central hole in the insert 19. The free or exposed ends of the leads are provided with clips 27 partially surrounded by exible shields 31 which are of different colors for purposes of identification of the leads. The left-hand or opposite ends of the leads 21, 23 and 25 are connected to switch means, generally indicated by the reference numeral 29, in a manner to be explainedA presently.
The switch means 29 includes a case of rectangular cross section comprising a channel-shaped piece 37 and a strip of insulation 38 which is secured between the free margins of the channel-shaped piece by screws 39. The channel-shaped piece is fastened by screws 40 to the housing 15. The strip of insulation is provided with three spaced fixed contacts 41, 43 and 45 having depending terminal lugs 47. The inner ends of the leads 21, 23 and 25 are connected to the terminal lugs of the fixed contacts 41, 43 and 45, respectively.
The switch means 29 has a movable switch member including a movable Contact 51 having a leading portion 53 fitting in a notch 55 formed in the insulating strip 38 and a trailing portion 57 which slidably engages the fixed contact 45. The movable contact 51 is in the form of a spring leaf and thus the leading and trailing portions of the movable contact yieldingly press against the strip 38 and the contact 45, respectively.
The movable contact 51 is connected by a screw 59 or other suitable metallic securing means to a button 61, of inverted T-shape. The button has a finger engaging portion 62 projecting through registering'slots 63 and 65 formed in back of the channel-shaped piece 37 and in the tubular housing 15, respectively. The button also includes a base portion 67 which, in the position shown, will not pass through the slots 63 and 65 and which is yieldingly pressed by the movable contact 51 against the underside of the back of the channel piece 37, as is clearly shown in Fig. 2.
A lamp 71 is connected between the terminals 47 of the fixed contacts 41 and 43. The lamp is positioned next to a lens 75 which fits within a suitable groove formed in the elastomer insert 17. As clearly shown in Fig. 2, the insert 17 has a radical fiange 77 which projects outwardly beyond the confines of the tubular housing 15, and the insert 19 has a similar ange 79 so that the control unit may be placed on a metal surface without danger of scratching the same.
Fig. 3 illustrates the control unit connected in one desired way into the electrical circuit of an automobile. The particular circuit shown is intended to illustrate one conventional form of ignition and starter circuit and is not intended to limit the invention. As shown, the circuit includes a battery 81 having its negative side grounded and its positive side connected by a conductor 83 to a double pole single throw switch 85, which is conventionally located on the dashboard of the vehicle and is of the key-operated type. One pole of the switch is connected by a conductor 87 to one terminal of the operating coil 89 of a solenoid switch in the starter circuit, the other terminal of the coil being connected to ground at 91. The movable element 93 of the solenoid Vswitch will engage spaced contacts 95 and 97 when the the distributor head 109. e ignition coil primary is conventionally connected by a conductor 111 to one side of the breaker points 113 of the distributor. A conductor 115 connects a condenser 117 in parallel with the oints. p Als shown in Fig. 3, the lead 25 has its clip connected to conductor 83 at any suitable place, such a-s a terminal box or the like. For convenience, the clip is shown attached directly to the conductor. The clip of the lead 23 is shown attached to the conductor 87 and the clip of the lead 21 is shown .attached to the conductor 103.
In use, with the engine may be turned over with the switch in the Fig. 2 off position by simply depressing the switch button 61 to bring the screw 59 into engagement with the fixed contact 43. This will serve toenergize the solenoid coil 89` to complete the circuit through the contacts 95and 97 and thus cause the starter motor 101 to turn over the engine. Itis apparent by comparing the Fig. 2 and Fig. 3 positions of the button 61 and of the movable contact 51,
that the trailing end of the movable contact 57 never 1 leaves the fixed contact 45 and the head of screw 59 is always disposed in a position above fixed contact 43.
It is normally desired not only to have the engine 4turn over, but also to start. To accomplish this the switch button 61 is shoved to the left to the Fig. 3 on position. This servesl to energize the lamp 71 and also the ignition system. Thuis, when the button 61 is subsequently depressed to bring the screwhead of screw 59 into engagement with fixed contact 43, the engine will be turned over with the ignition system energized to f start the engine.
When the switch button 61 is depressed in the Fig. 2 position of the button, the ignition circuit will be connected to the fixed contact 43 through the lamp 71. How,-
this arrangement the horn may be conveniently tuned the control unit connected as shown,
ever, the resistance of the lampi is of a magnitude to prevent the development of an operative voltage drop across theA ignition circuit. Thus the engine will not fireV until the button is moved to its Fig. 3 position, in which position the battery is connected directly to the ignition circuit through the fixed contact 41. Furthermore,when
the button is moved to its Fig. 3 position, without being depressed, the starter circuit is connected to the battery through the lamp 71. However, the lamp' resistance Will prevent the operation of the solenoid 89 until the button is depressed to by-pass the lamp circuit.
While the above-described use of the invention is the principal use,` the device has many other uses. For instance, not infrequently the automobile mechanic would like both hands free and would like to have the engine turning over without the ignition on. To do this, he will attach the clip of the lead 21 to the conductor 87 and the clip of the lead 25 to the conductor 8 3 and then shove the button Y61 from the left to right to `dispose the leading portionl of the movable contact 51 in engagement with the fixed contact 41. This will energize the starting motor, and the mechanic may ,simply place the control unit on any convenient portion of the vehicle leaving both hands free for work on the engine.
or otherwise adjusted without long blasts from the horn.
Obviously, the device may also be used as a flashlight and for all types of tests to test heater indicators, gas gauges and the like. Also, the device may be used to test the generators of various cars by either supplying current to the field of the generator, in which case either of the leads 21 and 23'may Vbe employed, or to ground the field in which case either `of suchleads maybe employed.
