increase the eiiiciency of snc-h machines.
According to -this open at both ends carries tween which the duced, each piston of a connecting rod to a cra enables the explosion crank of one of the most suitable position ing impulse, namely7 the connecting end.
yl"he invention is panying drawings.
Figs. l and 1I show points in the cycle. Fig. Hl shows action.
1 represents a cylinder open at both ends and 2 and 3 are two pistons working; therein. Piston 2 is connected to a crank 4f byv a coni piston 3 is connected to neet-ing rod 5 and invention two pistons beexplosive mixture or7 in the case of an air compressor, air', is introted by means This to take place when the 'crank shafts is at its for receiving the drivat or near the position with being connec makes an angle ot 90o rod. This is impossible with the ordinary cylinder which is closed at one a cylin nk shaft.
illustratedA in the accomdiagrainmatic View of the cylinder and piston at two separate one example of a valve a crank 7 by a connecting rod o.
The vtwo cranks 4 and 7 are geared together by gear wheels as indicated at 11, 8, 9-
and 10 Fig.
the pistons 2 and usual way. t will'be 4 when the said crank is at effective position for impuise of the piston 2. in the direct-ion shown Fig. 1".
l' shows the engine on the\ point of been introduced between 3 and compressed in the seen that the edect of the explosion lis transmitted to the crank or about its most receiving the driving The cranks revolve by the arrows in 'procating eni combustion engines and compressors and its object is to der `759,191, and in the' Union of South Africa November 12,
tien strokes are .completed'the cranks hai/ing turned through 4x70". The engine is now at the end et the suction stroke. 1s then compressed while the engine again arrives at the position shown in Fig. I.
lt will be seen' that the tiring and exhaust strokes occupy one revolution andY the snction and compression strokes likewise occupy one revolution. The engine therefore gives one explosion for every two revolutions o the crank si ft.
Fig. III shows in diagrammatic'orm one -to the invention. l
Eccentrics 12 and 13 are mounted respectively on the gear wheel shafts 9 and 8 and carry rods 14 and 15 which actuate exhaust valve 20 and inlet valve 1 9 through rockers 18 and 17.
The invention isnot limited to the particular example of valve gear shown; any suitable valve gear may be employed, the inven tion residing in the use of two pistons Iin an 4open ended cylinder as indicated.
I claim: In a reciprocating engine, two pistons adapted to reciprocate in opposite directions,
nearest t-oeach other.
in testimony whereof l'. aix my signature. i
