7 vice of the above character in either a water OIIQII cooled engine, and tor mount ng the device so that the coolingeilect of the water will not reduce the temperature of the ignition device. 7 I 7 lVith the above and other objects in view, the invention further includes the following novel features and'details of construction, to be hereinafter more fully described, illustrated in the,accompanying drawings and pointed out in the appended claims. a In the.draw1ngs: Y
Figural is a fragmentarysectional view showing a portion of an engine cylinder with the invention appl ed.
Flgure 2 1s a fragmentary plan view looking at the under face 'ot thecylinder head. 1 7 Figure 315 an enlarged iragmentary sectional view illustrating the manner of mounting the ignition devices.
Referring to the drawings in detail Wherein like characters of referencedenote corresponding parts, the-reference character 10 indicates the cylinder of an internal combustion engine which is water jacketed as shown at 11; after the manner of the usual water cooled engine A portion of the pistonwhich operates within the cylinder is indicatedat drawings comprises a porcelain body 13.
This body is tapered as indicated "at 1 4; to
' provide a pointed outer end and a relatively wide base. The body is provided with a concentrically arrangedfopening 15 whose outer end is counterbored as shown at 16. A. fasteningdevice in the formof a screw 17 extends through theopening 15 and is secure'd to the wall of the engine cylinder, while the head 18 ofthe screw is located within" the counterbore an appreciable dis-f tance from the end of the body 13. As shown in Figure 3 of the drawings, the taper of the body 13 togetherwith the wall of the bore 16' provides a relatively narrow annular heating point or flange 19 A metal plate 20'is interposed between the I porcelain body 13 and the adjacentwallo'f the engine cylinder. This plate is prefere ably formed of copper which possesses high heat-absorbing qualities.
, Preferably, the engine is started through the use of the ordinary spark plug, and when. sufficient temperature has been ob tained, current to the plug iscut off in any well known manner. Anynumber of heating elements may be utilized andtheseheating elements may be spaced upon the inside of the engine cylinder so that'when properly-' heated they will ignite a maximum amount of the gases'compressed Within theengine cylinder. 1 By reason ofthe formation of theend of the porcelain body 13, this point or end will become highly heated so that when the gases are compressed they will be promptly fired. By reason of the heat absorbing qualitiesofthe plate 20, water circulating through the jacket 11 will be prevented from changes in its forimcproportions and minor C details of construction and the right is here- "in reserved to make such changes as properly fall'within claims. I c
.Having describedthe invention what is claimed is: c 1. In an ignition device for internal com. bustion engines, a porcelain body adapted the scope of the appended to be secured to the inner face oft-he engine v cylinder headfa nd a metallic memberof high heat absorbing quality interposed between the device'and the wall of the cylinder.
2111 an ignition device for internal com bustion engines, a vporcelain'body adapted to be secured tofthe inner face ofthe engine let og'linder and having an opening theret rough and a counterbore at the outer end of the opening, a headed attaching device positioned within the counterbore and extending through the opening into the wall of the cylinder, and a tapered outer surface for the ignition device, said taper defining with the walls of the counter-bore, a narrow annular heating point.
3. In combination, an internal combustion engine having a water cooled cylinder, an ignition device comprising a porcelain body, means to secure the body to the inner wall of the cylinder head, and a metallic 15 member of high heat absorbing quality interposed between the ignition device and the wall of thecylinder.
4. In an ignition device for internal combustion englnes, a tapered porcelain body having a relatively Wide base and an open: ing extending through the body for the passage of anattaching member, said opening having a counterbore at the pointed end of V the base and defining a narrow annular heating point.
In testimony whereof We ,aflix our signatures.
