2 Claims.
This invention relates to breaker point mountings for distributors of internal combustion engines, and in particular includes a mounting wherein the position of a distributor point is adjusted while the engine is in operation.
The purpose of this invention is to provide an adjustable mounting for the normally stationary breaker point of a distributor wherein the position of the point may readily be adjusted without stopping the engine so that the engine may be tuned up to the highest possible efficiency.
Various types of mountings have been provided for breaker points of distributors but it is necessary to stop the engine or turn the engine slowly with the starter or by hand in order to set the distributor points, and after the points are set it is necessary to start the engine in order to determine whether or not the points are correctly positioned. With this thought in mind this invention contemplates a mounting wherein the position of the stationary point is adjusted by a screw driver or the like while the engine is running.
The object of this invention is, therefore, to provide means for mounting the normally stationary point of a distributor whereby the position of the point in relation to the movable contact points may be adjusted while the engine is running.
Another object of the invention is to provide an adjustable mounting for a breaker point of a distributor that may be incorporated in distributors now in use.
A further object of the invention is to provide an adjustable mounting for the normally stationary point of a distributor that provides means for adjusting the position of the point with the engine running which is of a simple and economical construction.
With these and other objects and advantages in view the invention embodies a clip mounted on the base of the distributor with an adjusting screw mounted in the clip with one end extended through the wall of the distributor and with the opposite end extended through and threaded into a breaker point mounting in the distributor.
Other features and advantages of the invention will appear from the following description taken in connecti n with the drawings wherein:
Figure 1 is a plan view showing a distributor with the improved breaker point mounting therein, with the distributor cap omitted and with part of the wall at one side of the distributor broken away.
Figure 2 is a cross section through one side of the distributor taken on line 2-2 of Figure 1.
Figure 3 is a detail showing a section on line 3-3 of Figure 2 showing the bearing stand for supporting a screw in the distributor.
Figure 4 is a detail showing a section taken on line 4--4' of Figure 1 illustrating an improved clamping screw whereby the stationary point of the distributor is held by friction.
Referring now to the drawings wherein like reference characters denote corresponding parts the improved breaker point mounting of this invention includes a base ii an adjusting screw I I that is pivotally mounted in a bearing stand l2, and a screw [3 that extends through a slot [4 in the base l0, which with the spring l5 frictionally holds the breaker point on the base 10 in adjusted positions.
The base ii], which is pivotally mounted on a post I6 is provided with a flange ll on which a breaker point 18 is carried and the flange is provided with an extension or nut I9.
The screw l i is threaded through the flange I1 and nut is and the intermediate part thereof is provided with an annular recess 20 that is positioned in a slot 2! in the bearing stand l2 whereby as the screw is rotated by a screwdriver or the like in a slot 22 in the outer end the flange I! and nut 19 on the inner end travel lengthwise of the screw, thereby adjusting the position of the breaker point 18 in relation to the breaker point 23 which is carried by the arm 24 that is also journaled on. the post It through an insulating bushing 25.
A sleeve 26 extends from the outer surface of the bearing stand l2 and a lock nut 21 threaded on the outer end of the adjusting screw clamps against the flange 28 on the outer end of the sleeve to lock the breaker point l8 in adjusted positions.
In the design illustrated in Figures 1 and 2 the sleeve 26 extends through an opening 29 in the wall 30 of the distributor 3| and with the outer end of the sleeve and adjusting screw extended through the wall of the distributor it is not necessary to remove the distributor cap to adjust the position of the breaker point. It will be understood that other means may be provided for turning the screw in the distributor through the wall of the distributor whereby the breaker point may be adjusted without the distributor cap being removed.
The bearing stand I2 is mounted on a distributor disc 32 by a screw 33 and the screw I3 that extends through the slot I4 of the base i0 is also threaded in the disc 32.
With the parts arranged in this manner the look nut 21 may be loosened and with a screwdriver extended into the slot 22 in the outer end of the adjusting screw the screw may be rotated, being held in the bearing stand 12, so that the flange ii on which the breaker point 8 is carried may be moved away from or toward the position of the breaker point 23 and with an instrument on the ignition system of the engine the breaker point 18 may be adjusted to obtain the most eflicient operation of the engine.
With such an instrument the average layman may adjust the position of the breaker point of a distributor without opening the distributor and without stopping the engine and the breaker point may be moved backwardly and forwardly until the engine runs smoothly.
It will be appreciated that the installation illustrated in the drawing is typical and the parts may be changed to compensate for distributors of diflerent designs.
It will be understood that other modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention.
What is claimed is:
1. In a distributor for ignition systems of internal combustion engines, the combination which comprises a distributor having an outer casing, a horizontally disposed disc positioned in said casing, a cam positioned above the disc, at post mounted on the disc, a breaker point base pivotally mounted on the post and having an upwardly extended flange on the outer end with a breaker point on the flange, said breaker point base having a slot therein positioned on a radius from the center of the post, a stud extended through the slot and threaded into the said disc, a spring on the stud frictionally holding the said breaker point base, a bearing stand positioned on said disc, a screw extended through the wall of the distributor journaled in said bearing stand and threaded into the upwardly extended flange of the breaker point base, a coasting breaker point arm pivotally mounted on said post and insulated therefrom, breaker points positioned on the said arm and flange of the breaker point base, a follower carried by the said arm and positioned to bear against the cam, and means resiliently urging the follower against the cam.
2. In a distributor for ignition systems of internal combustion engines, the combination which comprises a distributor having an outer casing, a. horizontally disposed disc positioned in said casing, a cam positioned above the disc, a post mounted on the disc, at breaker point base pivotally mounted on the post, and having an upwardly extended flange on the outer end with a breaker point on th flange, said breaker point base having a slot therein positioned on a radius from the center of the post, a stud extended through the slot and threaded into the said disc,
