Application filed September 30, 1908. Serial No. 455,421.

To all whom 'it may concern.'

Beit known that l, EDOUARD DENIPORT, a citizen or" the French Republic, and resident of Paris, France, have invented certain new anduseful Improvements in Spark-Distributers, of which the following is a specification.

This invention relates to spark distributers, for internal combustion engines, and has for its object, to provide a device Vof this kind which will occupy the minimum space, which can be easily and quickly takenl apart and assembled, and which can be readily attached to a motor.

In the accompanying drawing wherein is illustrated a preferred embodiment of my invention, Figure l is a central longitudinal sectional view thereof. Fig. 2 is a view from the bottom of the same. Fig. 8 is a top plan view. Fig. 4 is a sectional view on line A-B of Fig. l, and, Figs. 5 and 6 show respectively a side elevation and a top plan View of the member carrying the primary contacts.

In the drawing, a designates a shaft designed to be connected with, and actuated byl the internal combustion engine with which the spark distributor is to be used. Secured to this shaft and preferably keyed thereon as shown, is a rotary member comprising a metal hub 5', having an arm b2 provided With a cylindrical openin or recess b3 and a plate or block b4 of suita le insulating material partially surrounding the hub,- and provided with a cylindrical recess b5, provided with a metal lining b as shown. Within the opening or recess b3 is disposed a contact element c, which is spring pressed against a contact plate la., of suitable insulating material supported upon a metal ring la. having symmetrically disposed integral upstanding contact elements g (Figs. 5 and 6), with upper flat surfaces Hush with the upper surface of the insulating material, as shown in Fig. l. This insulating material serves to effectively insulate the ring h from the hub b', and the surrounding metal casing to be hereinafter referred t0. The ring k carries an arm h2, provided with openings h4 and h5 adapted to respectively receive abinding post (not shown) to be connected with a wire leading from a primary battery and any suitable means (not shown) as a rod or link, for shifting or moving the plate.

The contact carrying plate h is adapted to be rotated or shlfted around the shaft a through the limits of a certain angle alpha (Fig. 3) which is ordinarily equal to about 28o, to advance or retard the time of the spark in the motor cylinders.

It will be evident that, in the operation of the device, the rotation of the springpressed contact element c will cause it to contact successively with each of the contact elements g thereby successively closing a primary battery circuit through a suitable mduction coil (not shown), the oppositel `poles of the battery being in electrical conimunication with the arm 7L and the shaft a as indicated in Fig. l.-

It will be noted that the cylindrical recess lf* is disposed diametrically opposite the cylindrical recess b3, and that the metal lining of the formerl recess is in electrical coins inunication through metal strip Zi? with a metal button or knob, its which is engaged by a spring pressed metal rod or plunger z', mounted within the cylindrical casing z" to which is connected the binding post 2, to which one side of the secondary circuit of an induction coil (not shown) is in cornmunication. The rod or plunger z' serves not only to convey the ignition current :troni the binding post 2 'to the button or knob bs, but it also serves as an abutment to prevent ,any undesired displacement of the head or block .b,'as from the action of the spring associated with contact element c;

Disposed within the cylindrical recess bf" is a brush d, spring pressed against the cap or cover f, within which are secured a plurality of symmetrically vdisposed contact plugs e, having their surfaces l'ush with the lower surface of the cap or cover f, and

adapted to be successively engaged by the brush d in its rotation. The plugs e are connected with binding posts c', each of which is adapted to be electrically connected with a different spark plug of a tour cylinder internal combustion engine.

It will be understood that, in the rotation of the heador block l), the primary circuit being alternately kopened and closed, as described, the current induced in the secondary circuit of the induction coil, will pass from one end of such secondary circuit through the rod or plunger c', button be, metal strip e7, brush d, contact plug e, to and through the spark plug selected to receive it and back to the opposite end of the secondary circuit,` this current passing` successively through the spark plugs connected with the binding posts'e and being periodically interrupted uslorush ci moves out or nient with. Contact plugs e? es will lee readily understood.

A, suitable housingfor the deyiee is provided as shown. rllnis is to be readily secured in position as by clamping to a bearing Within Wluicn the she-ift a revolves2 by ineens of bolt While ,l have illustrated u orin of: my invention designed for use Witlrn four cylinder motor, it Wiil evident by changing the number of Contact elements e und g, the device cen-be used in connection with engines lia-Ning enynurnber olf cylinders. i
