OIL ARRESTER FOR SPARK PLUGS. i
Application filed August 14, 1920. Serial No.
To all whom itonaq concern Be it known that I, Gannon l NUss, citizen of'the United States, residing at Chicago, in the county of Cook Ld State of Illinois, have invented certain new and useful Improvements in Oil Arresters for Spark Plugs, of which the following is a specification.
This invention relates to an improved oil arr-ester for spark plugs and 'has as one of its principal objects to provide a device which will prevent showering of the terminals of a plug by oil thrown up by an engine piston, thus overcoming fouling of the plug and consequent short circuiting.
A further object of the invention is to provide an arrestcr having baitles for preventing access of oil to the plug terminals but wherein a free flow of gas within the device to the plug will be permitted, thereby insuring ignition.
And the invention has as a still further object to provide a device which may be readily employed in connection with substantially any conventional design of spark plug or engine cylinder.
Other and incidental hereinafter.
In the drawings: Figure 1 is a sectional view showing my improved arrester engaged with an engine cylinder of conventional design, an ordinary spark plug being illustrated upon the device,
Figure 2 is a View similar to Figure 1, showing a modification of the invention, and
Figure 3 is a transverse sectional view taken oii the line 33 of Figure 2, looking,
in the direction of the arrows.
. Peferring now more particularly to Figure 1 or" the drawings, I have shown my improved device in connection with an internal combustion engine cylinder 10 of conventional design. The piston of the cylinder is indicated at 11. In carrying the invention into effect, my improved arrester is formed with a tubular body 12 open at its ends and having meeting upper and lower portions lying atan obtuse angle with respect to each other and of substantially equal length so that the body is, will be observed, elbow shaped. Through the lower vertical portion of the body is a passage 13 opening at its inner end into a somewhat larger passage 14 through the upper angular-1y disposed portion of the body. Formed on the body at Specification of Letters Patent.
objects will appear Patented Apr. 4, 1922. 403,473.
and at the base of said nipple is an annular stop shoulder disposed to abut the wall of the cylinder. At its upper end the body is formed with a circumscribing enlargement having external wrench receiving faces and is internally threaded to receive a spark plug conventionally shown at 16. c
As will now be readily. appreciated, the arrester will firmly connect the spark plug with the cylinder and will support the plug in an inclined position with respect to the cylinder substantially in a plane at one side of the passage 13. Consequently, oil thrown up by the piston cannot, under ordinary cirstances, strike the electrodes of the plug to cause fouling thereof with consequent short circuiting. Furthermore, any oil which should, by chance, find its way into the arrester, will immediately drain back into the cylinder. I accordingly provide a device which will tend to insure proper firing of a spark plug. As the walls of a cylinder be come worn, oil, in increasing quantity, is thrown up by the piston of the cylinder, making it very difficult, due to quick fouling of the cylinder spark plug, to maintain the plug in proper working order. To cure this trouble cylinders are, at present, very often rebored and not infrequently, a whole new engine block is installed. By using the present device, either of the remedies indicated may be considerably delayed since the arrester will protect the plug from being showered: I
by oil pumped up by the engine piston.
n Figures 2 and 3 of the drawing, I have illustrated a slight modification of the invention. In this modification,'an engine cylinder is conventionally shown at 17 and the piston of the cylinder at 18, A tubular body 19 is employed as in the preferred construction, this tubular body being formed of angularly disposed portions the lowermost of which is provided with a reduced nipple 20 threaded into the spark plug orifice of the cylinder. Through the lower vertical portion of the body is a passage 21 opening into a somewhat larger passage 22 through the upper inclined portion of the body, all of this structure being, identical with the pre ferred form of the invention. Threaded into conventionally shown at 23. In this moditied structure. vertically spaced baffles 24 and are employed, the battle it being horizontally disposed and arranged at one side of the passage :21 at its junction with the passsage 22, while the battle 25 is inclined downwardly toward'the bafile 24 and is disposed at the opposite side of the passage .21 at its junction with the passage 22. As particu larly brought out in Figure 2 of the drawing, the battles overlap while, as shown in Figure 3. said baflles are respectively formed with straight free end edges being each substantially semi-circular. As will be seen,
the battles will tend to positivelv prevent the entrance of oil into the passage 22 of the arrester so as to effectually protect the plug against fouling.
Having thus described the inventiomwhat is claimed as new is:
In a device of the character described, the combination of an individual elbow-shaped body having angularly disposed portions and provided with a passage therethrough, the body being formed at one end for engagement with an engine cylinder and at its opposite end to receive a spark plug. a battle projecting into said passage substantially at the plane of the inside angle between the angular portions of the body, and a second batlle projecting into the passage substantially at the plane of the outside angle between said angular portions.
In testimony whereof I attix my signature;
GEORGE F. NUss'. t. 3.]
