IGNITION DISTRIBUTOR DRIVE FOR ATTACHMENT TO INTERNAL-COMBUSTION ENGINE CAMSHAFTS Filed Nov. 30, 1951 Inuantmr 1 ET. ELPIIR L. JERUME'.

Patented Nov. 18, 1952 IGNITION DISTRIBUTOR DRIVE FOR AT- TACHMENT TO INTERNAL-COMBUSTION ENGINE CAMSHAFTS St. Clair Le Roy Jerome, Ancaster, Ontario, Canada Application November 30, 1951, Serial No. 259,027

1 Claim.

My invention relates to an ignition distributor drive for attachment to internal combustion engine cam shafts and the object of the invention is to provide a drive gear connection assembly for fitment between the end of the horizontal cam shaft of an engine and the vertical drive shaft of .a vertically positioned ignition distributor.

The invention is particularly designed for use upon the engines of certain types of tractors wherein the distributor drive housing is horizontally arranged and attached to the end of the cam shaft and wherein it has been found that such arrangement is not altogether satisfactory as moisture is apt to seep into the distributor due to its horizontal position, and also that it is diflicult to open the distributor for adjustment and cleaning due to its location.

The desired object of my invention is to provide a driving connection fitment which may be secured to the engine block and coupled to the end of the cam shaft and upon which the distributor is mounted in a vertical position.

With the foregoing and other objects in view as shall appear, my invention consists of an ignition distributor drive for attachement to internal combustion engine cam shafts, constructed and arranged all as hereinafter more particularly described and illustrated in the accompanying drawing in which:

Fig. 1 is a side elevational view of the drive housing.

Fig. 2 is a vertical cross sectional view taken through the line 2-2, Fig. 1, and showing the distributor in dotted lines carried thereon, and

Fig. 3 is a horizontal cross sectional view taken through the line 33, Fig. 2.

Like characters of reference indicate corresponding parts in the different views of the drawing.

The driving connection is contained within a housing which comprises a horizontal cylindrical portion 2 open at one end 3 and closed at the other end 4. A second housing portion 5 is positioned vertically and is integrally attached to the housing portion 2 and opens thereinto through a communicating orifice 6 located in the vicinity of the closed end 4 of the housing portion 2.

The housing portion 5 is formed with a closed lower end I and an open upper end 8 formed with a flange 9 upon which the distributor assembly is supported. A distributor shaft It extends downwardly through the bore of the housing portion 5 and ha its lower end contained within a foot bearing II.

The open end of the housing portion 2 contains a bearing sleeve I2 which extends thereinto to the vicinity of the orifice 6, such sleeve containing a bearing bushing l3 extending along its length and within which a drive shaft I4 is journalled. The drive shaft 14 carries a coupling tongue [5 upon its outer end whereby the shaft is connected to the cam shaft of the engine. A helical gear 16 is secured to the inner end of the shaft and meshes with a helical gear l1 secured upon the distributor shaft [8, the gears meshing through the communicating orifice 6. The gears run in oil and for filling purposes an oil plug it is located in the end 4 of the housing portion 2.

The open end 3 of the housing portion 2 is formed with a flange [9 whereby the drive connection is secured to the engine block with the outer end of the shaft l4 coupled to the end of the cam shaft.

In fitting the drive connection in place it is only necessary to remove the standard horizontally positioned distributor assembly, and to attach my drive connection to the end of the engine block in place of the distributor assembly, with the end of the shaft M coupled to the end of the cam shaft. The distributor assembly is then positioned upon the top of the flange 9 of the housing portion 5 with the gears I6 and l l intermeshing, the drive then being ready for operation.

What I claim as my invention is:

A gear drive connection for fitment between the end. of a horizontal cam shaft of an internal combustion engine and the vertically positioned drive shaft of an ignition distributor, and comprising a horizontal cylindrical gear housing portion open at one end, a second gear housing portion open at its top and positioned vertically and integrally attached to and opening into the first gear housing portion in the vicinity of the closed end of such portion, the upper end of the second gear housing portion constituting a support for an ignition distributor, a shaft bearing sleeve contained within the open end of the first gear housing portion and extending to the vicinity of the opening into the second gear housing portion, a. shaft for connection to the cam shaft of the engine ahd contained within the bearing sleeve, a helical gear wheel secured upon the inner end of the shaft and positioned adjacent to the opening into the second gear housing portion, a distributor drive shaft contained within the second gear housing portion and supported within a bearing in the bottom of such portion, and a helical gear secured upon the distributor drive shaft and meshing with the other helical gear.
