UNITED STATES MARION H. DICKSON, OF LEWISTQWNJILLINOIS.

VIBRATOR STRUCTURE FOR SPARK COILS.

Application filed August 3, 1925.

To all whom it may concern:

Be it known that I, MARION H. DIGKSON, a citizen of the United States, residing at Lewistown, in the county of Fulton and State of Illinois, have invented certain new and useful Improvements in a Vibrator Structure for Spark Coils, of which the following is a specification.

This invention relates to spark or ignition coils for the ignition circuits of internal combustion engines, and particularly to improvements in the vibrator mechanism thereof.

An object of the invention resides in providing a vibrator mechanism for ignition coils wherein a plurality of contact points are carried by both the vibrating and stationary elements of the vibrator structure, which are adapted for cooperation so that any two points can be brought into engagement for control of the sparking circuit .through the coil, thus providing for the change of contact points tobring new contact points into cooperation without changing the vibrator or stationary elements of the vibrator structure.

The in ention comprehends other objects directed to the specific structural relation of parts which are more particularly pointed out in the following detailed description and in the claims directed to a preferred form of the invention, it being understood however that various changes in the size, shape and arrangement of these parts may be made without departing from the spirit and scope of the invention as hereinafter set forth.

In the drawing forming part of this application:

Figure 1 is a plan view of a coil unit showing the vibrator structure thereon.

Figure 2 is a side elevation of the vibrator structure and the upper portion of the coils shown in Figure 1 with the im' proved invention applied thereto.

Figure 3 is a detail view of the vibrator element.

Figure 4 is a detail elevational view of the stationary element of the vibrator structure.

While this invention is illustrated and designed more particularly for use in conjunction with the spark coils of ignition systerms used on the Ford type of automobiles, it is to be understood that it may be used with any similar type of sparking coils with of the housing 1.

closure made.

Figure 1 illustrates the housing for the main portion of the spark coil structure in which is mounted the laminated core 2, projecting slightly beyond the upper end The usual vibrator structure of the type of coil above mentioned includes a pair of supporting posts 3, on which is rigidly mounted the stationary element 4 in the form of a plate member which carries the stationary contacts for cooperation with the vibrator contacts as will be described. The forward end of the plate member 4 is formed with an opening to receive the threaded rod 5 which receives the adjusting nut .6 forthe purpose of changing the position of the stationary contacts relative to the vibrator contacts for adjusting the stroke of vibration of the vibratingelement. A fitting 7 is mounted on the upper end of the casing 1 of the coil, and supports the resilient strip vibrator element 8 having one end secured to the fitting by suitable screws 9. This fitting forms one terminal of the electric circuit through the vibrator structure, while the posts 3 form the other terminals thereof, which are both connected to the coil in a predetermined well known manner within the housing 1.

The present invention resides in a resilient strip 10, secured by suitable rivets or the like 11, at one end to the, end portion of the plate member 4, between the posts The opposite end of the resilient strip 10 rotatably mounts the disc 12 by the stud connection 13 extending through the disc and the resilient strip 10. This disc 12 is provided adjacent its periphery in spaced relation about the same with a plurality of contact points 14 which are adapted for sparking cooperation with contact points carried by the vibrator element 8 which will be presently described.

A disc member 15 is rotatably mounted on the free end of the vibrator element 8 through the medium of the rivet or stud 16 extending through the central portion of the disc and the end of the vibrator element. This disc is directly over the end of the pole piece 2 of the coil, and carries in spaced circumferential relation adjacent its periphery, a plurality of contact polnts 17 These points are arranged in such a manner that upon the securing of the vibrator element 8 to the fitting 7, one of the points may be properly positioned under one of the points 14 on the disc member carried by the stationary element for controlling the electric circuit through the vibrator mechanism. In the construction illustrated all of the points on one disc member will be positioned for overlying all of the contact points on the other disc member, but due to the angularityof the resilient member 10 with respect to the vibratory element 8 only the forward contacts on each disc member indicates that 18 will engage in the deenergized position. of therstructure for controlling the circuit therethrough. There will always be a small space between the other contacts on the disc member which may be moved by rotation of the disc members on the respective partsfor positioning in the position of the contact points as indicated at" 18 so that any contact point on any one of the disc members may be brought into circuit controlling relation with any contact on the other disc member. These disc mem bers may be provided with protections 19 from the periphery thereof for providing suitable handles bywhich the discsv may be grasped for manualrotationto change the engaging contacts of the vibrator structure.

From the above description it will thus be clearly understood that a plurality of con tact points are provided on the respective elements of a vibrator structure for spark coilswherein any one of the contactpoints carried by, eithermember may be brought into, engagement, with any one of the contact points on the other element in order that new and smooth contact points may be used for controlling the circuit through the vibrator structure without removing or replacing either of the vibrator elements,

merely by rotating the disc members 15 and 12 to position the desired contact points in the positionindicated by the numeral 18 for cooperative engagement in circuit controlling relation,

Having thus described the invention, what I, claim, is:-

1. A spark coil for ignition systems of an internal combustion engine having a vibratormechanism; comprising a stationary element, a vibratory element, rotatable members, one of said rotatable members being mounted on each element, and a plurality of contact points mounted in spaced relation on said rotatable members, any one contact member being adapted for positioning to engage any one contact on the other member for circuit controlling cooperation.

2. A spark coil for ignition systems of an internal combustion engine having a vibrator mechanism; con'lprising a stationary element, a vibrator element, disc members rotatably mounted on each of said elements in opposed relation, and a plurality of contact points mounted in spaced relation on each disc member, one contact point on one member being adapted for sparking cooperation with any one contact on the other member;

3. A spark coil for ignition systems of an internal combustion engine having a vibrator mechanism; comprising a stationary ele ment', a vibrator element, disc members rotatably mounted on each of said elements in opposed relation, and a plurality of contact points mounted in spaced relation on each disc member, one contact'point on one member being adapted for'sparking cooperation with any one contact on the other member, and members on said disc members engageable'for manual rotationof the members to change cooperating contact points.

4. A spark coil for ignition systems of an internal combustion engine having a vibrator mechanism,comprising a stationary element, a vibratory element, movable members, one of said members-being mounted on eachelement, and a plurality of contact points mounted in spaced relation on said members, any one. contact member being adapted for positioning to engage any one contact on the other member for circuit controlling cooperation.

In testimony whereof I afiix my signature.
