Abstract
Abstract The flexing of the rocker arm studs of an internal combustion engine is prevented by use of an apertured restraint bar rigidly mounted on the cylinder head casting by means of brackets. The apertures in the restraint bar circumscribe but do not rigidly structurally interconnect the rocker arm stud nuts which define extensions of the studs. The position of the stud nuts on the studs may be varied to adjust valve clearance without removing or repositioning the restraint bar.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
Apparatus for preventing undesired movements of internal combustion engine valve operating members comprising: rocker arm stud extension means, said extension means adjustably engaging each of a plurality of linearly aligned rocker arm studs, engine valve clearance adjustments resulting from movement of said extension means on the studs; locking means for preventing vibration induced rotational movement of said extension means on the studs; elongated bar means, said bar means defining a plurality of spaced apertures, said bar means apertures circumscribing each of said stud extension means of a linearly aligned array of rocker arm studs for preventing defLectional motion of the studs, said bar means apertures being sized so as to define a clearance between said stud extension means and the walls of said apertures whereby rotational movement of said extension means is not impeded by said bar means; and bracket means, said bracket means comprising a pair of opposed brackets adapted to respectively engage opposite ends of and solely support said bar means on an engine.

Dependent Claim
166 words
Apparatus for preventing undesired movements of internal combustion engine valve operating members comprising: rocker arm stud extension means, said extension means adjustably engaging each of a plurality of linearly aligned rocker arm studs, engine valve clearance adjustments resulting from movement of said extension means on the studs; locking means for preventing vibration induced rotational movement of said extension means on the studs; elongated bar means, said bar means defining a plurality of spaced apertures, said bar means apertures circumscribing each of said stud extension means of a linearly aligned array of rocker arm studs for preventing defLectional motion of the studs, said bar means apertures being sized so as to define a clearance between said stud extension means and the walls of said apertures whereby rotational movement of said extension means is not impeded by said bar means; and bracket means, said bracket means comprising a pair of opposed brackets adapted to respectively engage opposite ends of and solely support said bar means on an engine.
Claim 5
Dependent Claim
17 words
The apparatus of claim 1 wherein said extension means each comprise: an elongated rocker arm stud nut.
Claim 6
Dependent Claim
83 words
The apparatus of claim 2 wherein said locking means comprises: set screws associated with each of said stud nuts, each of said set screws being provided with a tool engaging socket in one end thereof, said set screws having an external thread complementary to said stud nut internal thread whereby said set screws may be located within said stud nuts and adjustably positioned with respect to the ends of the rocker arm studs by means of a tool inserted into said stud nuts.
Claim 7
Dependent Claim
23 words
