VALVE MECHANISM son INTERNAL-COMBUSTION ENGINES.

To all wlwmfe't may concern; Be it known that 1, ERNnsT FUCHS, .c1t1- zen of the French Republic, residing at Paris, Department of the Seine, in France; and whose post-office address is 111 Boulevard Exelmans, in the said city, have'in vented certain new and useful Improvements in or Relating to Valve Mechanism for Internal-Combustion Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its ob cct an arrangement of valve control mechanism forinternal combustion engines and consists principally in placing the shaft on which the valve tappet mechanism for controlling the drawings, which show diagrammatically and by way of example, two constructional forms I of valve control mechanism for internal com bustion engines withthe cam shaft above the cylinder.

Figure 1 is a plan view of an arrangement controlling four valves and employing two cams for the exhaust-with two separate tappet levers and a single cam for the admission and one double tappet lever.

Figure 2 is a vertical cross section on the line A. B., Figure 1.

Figure 3 shows a modification partly in section of an arrangement for controlling four valves but employing one cam for fuel admission and exhaust and a double tappet lever for the fuel admission and a double tappet lever for the escape.

' Figure 4; is a vertical cross section on. the line C. 1)., Fig. 3, and Fig. 5 is a sectional detail view of the tappet lever bearings.

The arrangement Figures 1 and 2 is shown as applied to the control of four valves; two, 1. and 2, serving for the admission of fuel, and two, 3' and 4, acting as exhaust valves,

Specification of Letters Patent.

two cams 5 and 6being employed for the exhaust with two separate tappet levers-T and 8 and a single cam 9 for the admission in Figures 3 and lis also arranged to con trol four valves, two 1, 2 acting as admission valves and two, 3, ,4: as escape valves by 'utilizingonly one cam for the admission of fuel and the exhaust with one double tappet lever 16 for the admission and a double tappet lever 17 for the exhaust. 7

The shaft 11 on which the fuel admission and exhaust tappet levers oscillate and the cam shaft 12 are parallel and they are situ- 'ated in the vertical. plane passing through the axes of the cylinders and placed between the ends of the tappet rods.

The tappet levers carry friction rollers 13 which are permanently in contact with the remand the said friction rollers are one end, the other end bearing onthe valve tappet rod 14:.

Further, the height of the tappet lever shaft above the cam shaft is adjustable by means of the keys blocks or wedges 19 orin any other convenient manner, the journals 20 for the shaft 11 carrying the tappet levers being guided in the bearings 21 rigid with the cam shaft bearings.

The arrangement hereinbefore described permits of the space occupied by the valve controlling mechanism being reduced to a minimum, of being able to easily dismount the tappet levers and even the cam, of modifying the regulation of the distribution'by varying the distance between the tappet lever shaft and the cam shaft, and finally of easily. enclosing the distributing or controlling mechanism in a casing 18 thereby avoiding all projection of oil above the cylinders.

I claim:

An overhead valve operating mechanism for internal combustion engines, comprising ER vEs'r scans, on rears, FRANCE, ASSIGNOR To LOUIS RENAULT, or BILLANCOURT,

plane pass Patented May 9, 1 922. Application filed March 21, 1919. Serial N0. 286,563. r

"a pair of tappet levers of U-shape adapted to control onerpair of valves, a pair of tappet levers of .inverted \/-shape for controlling another pair of valves oppositely arranged to said first mentioned pair of valves, a com mon shaft for pivotally supporting said tap said shaft, cam-engaging rollers carried by said extensions, and means for mounting said levers on their supporting shaft ln sueh relation to' each other that said rollers can be engaged by the same cam on the cam shaft, the tappet lever shaft and. the eam'lever shaft being positioned in a plane passing vertically through the axis of the; ngine cylinders.

' In testimony whereof I aflix my signature, I in presence of two witnesses.
