Title: Improvements in or connected with Eccentric Valve Gear for Engines.
IPC: F01L31/14
Filed: 1917-10-23
Abstract: 119,721. Mavor & Coulson, and Moore, M. S. Oct. 23, 1917. Eccentrics.-In a coal-cutting machine having four single-acting cylinders on opposite sides of the crank-shaft, the valves are driven from eccentrics B arranged on sleeves loose on the main shaft C. The sleeves carry toothed wheels B', A<1> in mesh with wheels B<2>, A<2> on a countershaft D which is movable axially. A wheel E<1> fixed on the main shaft engages a wheel E coaxial with the countershaft and held against axial movement. The wheel A<2> carries a projection G which engages a recess G<1> in the wheel E, Figs. 4 and 5, or a number of projections may be provided engaging a number of recesses. The eccentrics are adjusted by withdrawing the wheel A<2> out of engagement with the wheel E and rotating it. Re-engagement is effected by a spring H<1>. Stops are provided on the wheels E<1>, A<1> to limit their movement. In a modification, sprocket wheels connected by chains are mounted on the main shaft and the countershaft. The adjacent sprockets on the countershaft are connected by a cone clutch, or one is mounted on a toothed part of the shaft which engages recesses in the other sprocket.

Title: Driving system for a plurality of rotary piston internal combustion engines
IPC: F02B53/00
Filed: 1963-04-22
Abstract: 1,007,193. Rotary-piston internal combustion engines. NSU MOTORWERKE A.G. April 22, 1963 [April 21, 1962], No. 15748/63. Heading F1F. [Also in Division B7] A drive system for at least two rotary-piston I.C. engines whose output shafts are coupled together to drive a single load and whose intake passages are supplied from a common manifold equipped with a throttle valve, comprises in the case of three engines M 1 , M 2 , M 3 , Fig. 3, having output shafts 1, 2, 8 respectively, a 2:1 reduction gearing Z 4 , Z 3  and a free wheel F 2  between the shafts 8, 1 and a 2:1 reduction gearing Z 2 , Z 1  and a freewheel F 1  between the shafts 1, 2. The freewheel F 2  disengages the engine M 3  and the freewheel F 1  the engines M 3 , M 1 . A belt drive from the output shaft 2 which is connected to the load to be driven is connected to a speed governor R which controls throttle valves K 1 , K 2 , K 3  in the intake lines 5, 6 and 9 respectively to the engines M 1 , M 2 , M 3  and a further throttle valve K 3 <SP>1</SP> in the line 5. In the rest position of the engines, the valves K 3 , K 3 <SP>1</SP> are open and the valves K 1 , K 2  closed. To start the engine after the operation of the main throttle valve HK from the "gas" pedal of a motor vehicle, the engine  M 3  is started by a starter St. This engine drives the output shaft 2 through the engines M 1 , M 2  which are both idling since the valves K 1 , K 2  are closed and remain closed up to a speed of 500 R.P.M. of the output shaft (2000 R.P.M. of the engine M3). At this speed the governor R opens the valve K 1  to bring in the engine M 1  which is rotating at 1000 R.P.M. to add its output to the shaft 2. On the output shaft speed reaching 1000 R.P.M. (M 1  speed 2000 R.P.M. and M 3  speed 4000 R.P.M.), the throttle valve K 2  is opened to bring in the engine M 2 . On a further rise in speed of the output shaft to 1500 R.P.M., the speed of the engine M 3  rises to 6000 R.P.M. its maximum permissible, at which the speed the valve K 3  is closed by the governor R to cut out this engine. At an output shaft speed of 3000 R.P.M., the speed of the engine M 1  reaches its maximum permissible 6000 R.P.M., whence the valve K 3 <SP>1</SP> is closed to cut out this engine; In the event of the output speed diminishing, the valves are operated to first bring in the engine M 1  at 1500 R.P.M. and then the engine M 3  at 1000 R.P.M. The invention is also described to control two engines, i.e., with the engine M 3  entirely omitted. The starter St then being mounted on the engine M 1  and the gearing Z 3 , Z 4 , the freewheel F 2 , output shaft 8, line 9 and throttle valves K 3 , K 3 <SP>1</SP> omitted.
