Definitions
- a means forming a part of the device prevents and limits the adjustment beyond a predetermined angular movement.
- FIG. 1 is an elevational view of an ignition distributor to which the invention has been applied
- FIG. 2 is a plan view partly in section taken along line 2-2 of FIG. 1, with the locking means removed,
- FIG. 3 is similar to FIG. 2 showing the range of movement of the cam adjusting portion and FIGS. 4 and 5 are plan and elevational views of a modification of the invention.
- an engine block is shown on which is mounted in vertical position in a box 10A an ignition distributor 12 of conventional ignition system for the engine on which it is mounted, and may be provided with a rotatable breaker cam 14 mounted on the vertical distributor shaft 16 rotatably mounted in the distributor housing 10 in a conventional manner.
- the cam 14 may actuate breaker points 20 or cooperate with an electronic timing device depending on the type of ignition system to be utilized for the engine.
- a conventional centrifugal advance govenor 22 and a conventional vacuum advance device 24 can also be provided if desired for controlling the ignition timing advance or retard depending on load and/or speed of operation of the engine.
- the distributor is conventional.
- the neck portion of the distributor housing is provided with a shoulder 12A, which rests on the upper surface of the block 10 as shown, the shoulder also forming a seat to which is affixed a horizontallyextending arm 26 which may be welded or brazed thereto or it may be clampled thereon as shown in the modification in FIGS. 4 and 5.
- the outer end of the arm 26 is bifurcated to form an opened slot 26A, which loosely embraces an eccentric cam 28 so that the cam is readily rotatable therein.
- the cam 28 is permanently affixed as by brazing or welding to a vertical threaded stud 30, which is fitted vertically into a threaded bore 30A in the block 10 a suitable distance from the vertical axis of the distributor housing 12 as best seen in FIGS.
- the threaded stud 30 is screwed into the bore 30A, a sufficient distance to position the cam 28 within the thickness dimension of the arm 26, so that the cam may be rotated about by the turning of the stud 30 without displacing it from the slot 26A in the arm.
- a hexagonal slot 303 is provided in its upper end as shown in FIGS. 2, 3 and 4, to cooperate with a conventional Allen wrench W as is well-known in the art.
- the rotation of the cam 28 is limited by the cam contacting the bottom wall 268 as shown in FIG. 3 which will maintain the cam within the vertical thickness dimension of the arm 26.
- the arm 26 is locked in position on the upper surface of the block 20 by drawing down a hexagonal nut 32 against washer 34 and spring washer 36 to clamp against the upper surface of the arm 26 by the use of a conventional wrench of suitable size. This is best seen in FIG. 1, where the parts are shown in assembled loose relation before the ignition timing adjustment has been made.
- FIGS. 4 and 5 a modification of the affixing means for the arm 26 is shown, wherein the portion of the arm locked to the shoulder 12A is bifurcated to provide a pair of spaced portions 40 and 42 which are thickened and fitted with a bore, one portion of which is threaded to cooperate with a clamping bolt 44. This allows the portions 40 and 42 to be drawn together to clamp against the shoulder 12A of the distributor 12.
- a bifurcated arm affixed to the distributor adjacent the engine block, a stud rotatably mounted on the engine block including a cam affixed thereto to cooperate with the bifurcated portion of the arm to move the arm angularly through a predetermined angular movement, means on the stud to cooperate with a hand tool to control the angular movement of the arm, and means cooperating with the stud to lock the parts in a fixed position.
- the device defined in claim 1 further characterized by providing a resilient means for locking the parts in fixed position.
- the device defined in claim 1 further characterized by providing an adjustable means for affixing the arm to the distributor.
