Abstract
An adjustable timing gear arrangement having an output shaft and a camshaft operable in timed relationship with the output shaft comprises a first rotatable drive member driven by the output shaft with a second rotatable drive member mounted on the camshaft and operably connected with the first drive member for rotation in timed relation therewith. The second drive member is mounted on the camshaft for rotation on a common axis with the second drive member and the camshaft and is secured thereto to fix the angular relationship of the members. The mounting permits limited relative angular rotation of the members when the members are not so secured. For adjusting the relative angular positions of the second drive member and the camshaft there is an assembly including an unthreaded, cylindrical stud extending from the camshaft into a radially extending slotted opening through the second drive member. The opening includes angularly spaced, parallel sides. An eccentric cam is freely rotatable on the cylindrical stud and closely fits between the parallel sides of the slotted opening. A tool receiving portion on the cam is arranged for permitting selected rotation of the cam to cause relative angular adjustment of the second drive member relative to the camshaft. The slotted opening and the eccentric cam have cooperating interengaging portions lying in a plane perpendicular to the axis of rotation of the camshaft for retaining the cam in the slotted opening while permitting free rotation of the cam relative to the second drive member.
