The object of this invention is to providean engine either an internal combustion engine or a steam engine or a pump which. has but I haust pipe is shown on the outer side of the cylinder and an exhaust port 21 of each cylinder communicates from theinside of the cylinder to this exhaust pipe.

low main shaft of the engine. The invention will be more fully understood from an inspection of the accompanythe bases of the bearings aratus for converting reciprocating-motion into rotary motion. I 1

The object-of this invention is, further, to

10 provide a piston'in a cylinder which when it 20 ast the inlet manifold to heat the incoming el. Thisexhaust passage and intake manifold are preferably located within the holing' drawingsin which Figure 1 is a section throu h the cylinders of an engine of my improve type and also showing the main shaft n section. Figure 2 is an end view of an en- 80 gine such as shown in Figure 1 and consisting of four units, the upper one beingshown in full lines and partly broken away to show the interior construction. I

The cylinders are shown at 10 and 11 and are opposed and axially aligned. Each cyl-' inder contains a piston 12 and these pistons are connected by a shaft 13/which may have a central support such as the bearing 14 in which the shaft both 'rotates and slides...

Abutments 15 are placed where the rear cam 'faces 16 of the pistons bear on them t9 cause the rotation of the piston when the "piston is reciprocated toward the abutment. In the form shown these abutme'nts are provided by I 14. The main shaft is shown at 17 and is rotated bya gear17' in mesh with a pinion 18 on the shaft 13, the shaft 13 being 'arra'n ed so that it can rotate the pinion 18 but slide therein, and I show I a feather 19 for such function. A main exits power stroke the other piston is operating on its compression stroke or its scavenging stroke. The ports 21 are opened by reason of the piston moving far-enough to uncover the I port 21'. A k

The engine I illustrate is an internal coinbustion engine and I/ show spark plugs 22 to indicate the power end of the pistons.

At the inner side of each piston is ,a port 23' and within the shaft is an exhaust passage 24 and aninlet manifold 25, the latter carrying the fuel mixture. This exhaust passage and the intake manifold rotate with the shaft so that the exhaust'opening 26 of the exhaust passage 24 and the inlet passage 27 of the intake manifold functionally register with the -port 23 in a cylinder.

In the case of four units,-each consisting of two cylinders as shown in Figure 2, they main shaft 16 is" rotated at halfthe speed of the rotation of'the shaft 13 and this operates r j these cylinders in their proper sequence so that theymay successively operate to rotate the main shaft. As these cylinders can be arranged to have their operation overlapping and in the absence of unbalanced valves and crank shafts, vibration is eliminated.

A manually operated control member 1s interposed between the passages in the shaft i and the port 23 of the cylinder. This is illustrated as a sleeve 28 which has a flange 29 regulated by a pinion 30 which the teeth 31- on the flange.

The pinion 30is on a shaft ates a similar pinion on the other end ofthe engine. The sleeve 28 has the, port or passage 33, one for each cyl1nder, and as the sleeve is advanced or retreated the duratlon of the exhaust and, more particularly, the 95 point of cut-off of the fuel can be controlled. In this engine the exhaust at first is through the major opening 21 and when this is closed by the return of the pistonlthe' gases are forced out through the ports 23, 26 and 33 m9 ,7

meshes with A 32 which operand thus through the exhaust passage 24. This insures a complete scavenging and also heats the intake manifold 25 and thus heats the incoming fuel. As the shaft turns it x presents the intake manifold, the port 27 comes around to port 23, the piston is on its suction stroke and the cylinder is changed.

' The sleeve 28 by its adjpstment varies the reciprocation.
