' IGNITION DEVICE.
tion Devices, of which the following is a specification, reference being had therein to the accompanying drawing. This invention relates to an ignition device especially adapted to befmounted directly upon the spark plug of a hydrocarbon engine, and the object of the invention is to provide an extremely small and compact yet highly efficient device comprising a coil' carrying casing having a" central recess whereby it may be readily mounted upon a spark plug and a coil having a hollow center 7 portion mounted in said casing and surrounding said receiving recess, said casing being also provided with simple and effective means whereby the device'may be detzichably connected to the ordinary spark further object of the invention is that by mounting this device directly upon the spark plug it serves as an insulating hood or cap to; inclose, cover and protect the otherwise exposed conducting parts of the Then again, it eliminates all spark plug. high tension wiring thereby obviating the necessity of heavy insul'ationagainstmoisture or other external influences.
With these and other objects in View, the invention consists of certain novel features of construction, as will be-more fully' described and particularly pointed out in the appended claims. v
Of the accompanyin drawings: Figure 1is a sectional view 0 the casing and coil showing the same applied to a spark plug of "standard construction. .Figl 2'is a modified construction of casingshowing the same as being adapted to be filled from the bottom instead of from the top as that illustrated in Fig. 1. Fig. 3-shows the upper portion of a spark plug with the'spring wire contact connected thereto. Fig. 4-is a sectional plan view of the-clamp for attaching the device to the spark plug. Fig. 5is a wiring diagram of my improved ignition device.
Iteferring to the drawings, 10 designates a cylindrical casing formed preferably by the molding of insulating material, the same Specification of Letters Patent. Application filed August a, 1911.
Patented Dec. 12, 191 1.
Serial No. 642,208.
' being provided with a bottom portion 11 and a central tubular member 12 forming a central longitudinally disposed recess 20 for the reception of the upper end 13 of the ordinary spark plug 14;, an outer annular chamber 27 being formed around the inner central recess for the reception of the coil.
hereinafter described. A contact member 15 ismolded or otherwise secured into the base portion of the casing to which the lead wire, not shown, may be connected. Into this base portion is also molded or otherwise fixed a metal clamping member 16 which is preferably made to conform to the nut portion of the standard spark plug and is split as at 17 and provided with a binding screw 18 for the purpose of being set up-firrnly to secure the casing rigidly onto the spark plug of an engine. A cap 19, alsdof insulating material, maybe threaded or otherwise socured into the ;upper end of the casing. A contact plate 21 is preferably secured to the inner side of said cap and projects out therefrom into the upper end of the coil chamber.
In this device I preferably use a high frequency coil, that is, a coil which depends for its excitation upon the oscillatory dis charge of a condenser. This coil consists of an outer primary and inner secondary winding and is particularly well adapted for my present purpose as it is provided with a hollow middle portion and is adapted to be inserted into the annular chamber 27 and about the spark. plug receiving recess 20. Oneend of the secondary winding 23 of this coil may-be connected at its upper end to the contactplate 21' by the wire 22, the other end of said coil-being grounded on the engine through the wire 24, clamp 16 and spark plug and when the coil is placed in position over the spark plug this contact spring engagesv the plate 21 thereby completing the circuit through the plug.
In the modified form of easing illustrated in Fig. 2 the same is also made in a cylindrical form, the top portion being provided with a fixed head or cap 28 thereover into which is molded or otherwise fixed the contact member 15. After the coil 29 has been placed in the coil chamber 27 from the bottom end of the casing, a head'30 having a inductance 36 thence through wire 37 to one applied to a four cylinder engine in which.
34 designates the source of energy of comparatively low voltage which is comlected to one wire 35 which passes through the point 38 of the interrupter through to the other interrupter point- 39 and wire 40 back to the source of energy. In other words, the inductance and interrupter are in scries. The terminal 38 of the interrupter is ber 44 which is insulated at 44.
connected to ground through the. wire 45. One terminal 41 of the condenser 42 is con nected to the point 39 of the interrupter. The other terminal 43 of said condenser is connected to the rotating distributing mem- The distributer contact points 46,. 47, 48 and 49 are adapted to receive the current from the rotating distributing arm 50 to conduct the same to their respective ignition devices 51 and through its spark plugs 14 to ground, in other words, the condenser connected in series with the primary winding of the respective ignition devicesacross the contact points of the interrupter. It will be understood from the above that the condenser discharges through the primary winding of the high frequency coil, mounted upon the spark plug. I In the operation of this device the con tact members 38 and .39 are closed by the mechanical action of a rotating cam illustrated and described in my copending application Serial No. 625,075. Immediatel upon the completion of the circuit throug said interrupter the points 38 and 39 are instantly separated by the mechanism described in said co-pending application. The inductance coil 36 charges the condenser 42 which instantly discharges through the distributer and the proper coil. This discharge through the primary winding of said coil induces the high. frequency spark in the gap 52 in the spark plug 14 serving to ignite the mixture in the englne.
I claim:
1. In an ignition device, a coil provided witha hollow center portion for the reception of a spark plug, and a contact to complete the circuit through said spark plug when the device is applied thereto.
2. In an ignition device, acoil provided with a hollow center portion for the reception of a spark. plug, a contact to complete the circuit through said spark plug when the device is applied thereto and an insulating casing inc-losing said coil.
3. In an ignition device a coil carrying casing rovided with a central longitudinal recess or the reception of 'a spark plug, a coil provided with a hollow center portion mounted in said casing and surrounding said spark plug receiving recess and a contact in said recess to complete the circuit through the spark plug when the device is applied thereto.
4. In an ignition device a coil provided with a hollow center portion for the reception of a spark plug, and "a contact to com' plete the circuit through said spark plug when the device is applied thereto, and means for securing said device in position.
5. In an ignition device, a coil provided with a hollow center portion for the reception of a spark plug, and a contact to complete the circuit throu b said spark plug when the device isapp ied thereto and an insulating casing inclosing said coil'and means for removably securing said casing to its spark plug.
In testimony whereof I afiix my signature in presence of two witnesses.
