GEORGE H. BICKE, 0F GIhTCINNATI, 0M0.
SPARK PLUGa Application filed December 18, 1927. serial No. $40,589.
The object of my invention is to produce a spark plug for automobile engines which shall be very simple in construction and highly efiicient in use, which will not foul by reason of the engine pumping oil or from any other reason.
In carrying out my invention I arrange the electrodes in such position that sediment, oil, carbon, gas and the like from the ignited charge will not reach the oints of said electrodes, and thus their polnts will always be clean, insuring perfect sparking.
Another feature consists in employing an extra electrode which can be used when the electrode in use is burned out or destroyed. It is not in the way and when needed for use it can be bent over to a proper spacing point.
The features and advantages of my invention will readily become apparent from roadin the following specification: I
* Tn the accompanying drawing forming .part of this specification:
Fig. 1, is a'view in elevation of my spark plug, showing one side of said glug,
Fig. 2, is a similar view ta en at right angles to Fig. l, i
Fig. 3, is a sectional view of the lower end of the-plu to show the relative position of the electro es and other parts, taken on line 3-3 of Fig. 2, part of the plug being broken away, and
Fig. 4 is a sectional view, taken on the line 4-4 of Fig. 1.
Referring to the drawing, the spark plug itself or body or shell thereof is marked 1, a cylinder skirt is marked 2, provided at its mouth with a baffle disk 3, having arms 4, which joih it to the skirt 2.' Thus apertures as 5 are formed. By screw threads 6, the
lug is connected in the'engine cylinders.
he usual positive electrode 7 is employed and'in connection therewith a ground electrode 14. is used, connected to the baiHe 3 at 13,- so that when the electrode current is applied in connection with the timer, an electric spark is produced between them. In carryin out my invention, I arrange these electro es or wires differently and to better advantage by positioning them in connection with other parts, so that the s ark ends of the electrodes will be above the ottom of the skirt, so that when an explosion takes place, none of the exploding elements or oil will reach the points of said electrodes, and consequently they will always be kept clean and 111 good working order.
If the electrode 14 should burn out, as
sometimes occurs, I provide an auxiliary electrode 15, which is in an abnormal posit'on and when the electrode 14 is destroyed, the electrode 15 can be bent over to the roper sparking positionwith the electrode thus saving time and money and insuring great convenience.
A spark plug. of this character will last loner than the ordinary spark plug and wil do better work.
I do not wish a) be limited to the ma and pro ecting downwardly from the lower edge of the same, arms projecting downwardly from the lower edge of the skirt, an imperforate disk-shaped bafie connected to the lower ends of the arms and spaced from the lower edge of the skirt, a central electrode extending into the shell and skirt, insulated from the shell and skirt, and having its lower end terminating within the skirt, but in close proximity to the lower edge of the latter, and a second electrode connected to the disk and projecting upwardly into the skirt and terminating in close proximity to the lower end of the central electrode, the opening between the bafile and the lower edge of the skirt permitting access 'to the points of the electrodes for cleaning purposes.
2. A spark plug, including a metallic shell having a depending skirt, arms dependin, from the skirt, an imperforate disk-shapes. bafile carried by the arms in spaced relation to the lower edge of the skirt, a central electrode extending into the skirt and terminating within the latter and a pair of malleable electrodes attached to said diskshaped heme and projecting upwardlg and terminating within the skirt, one 01 said malleable electrodes having its upper end arranged in close proximity to the lower end of the central electrode.
3. A. spark plug, including a metallic shell having external threads adapted to engage the threads of a spark lu aperture of an engine cylinder, a cy in rical metallic at I claim as new and my invention external threads to engage the threads of an engine cylinder, a skirt united with the shell skirt integral with the shell and depending from the latter, metallic arms depending from the skirt and merging into the lower of'the latter, a metallic disk-shapeded e badle of substantiallythe same diameter as the external diameter of the skirt, integral with said arms, the baffle being spaced from the lower edge of the disk to provide an opening, a central electrode extending into the shell and skirt, and having its lower end terminating within the skirt, and a pair of electrodes projecting apwardly from the baflle and terminating within the skirt, one electrodeof the pair having its upper end arranged in close proximity to the lower end of the central electrode, and the other electrode of the pair being formed of malleable material to permit the same to be bent toward and away from said central electrode.
In testimony whereof,'I aflix my si nature at the city of Cincinnati, county of llamilton, and State of Ohio, this 15th day of December, 1927.
' GEORGE H. RICKE.
