Application iled December 15, 1916. Serial No. 137,092.

"To aZZ w/Lom z't may concern:

.lo gmes, and declare the following to be a full, *clear-, and exact `description of the saine, Such'as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specication.

his invention relates' to rotary internal combustion engines. It comprises a battery lof cylinders having a cylinder which approach each other together and withdraw from each other at the same The -members of adjoining pairs of pistons are connected up to move together,

`as will more fully appear hereinafter'.

2 is a plan view partly broken away.

a designates a cylindrical housing in which cylinder here shown as having two longitudinal bores or cylinders o for the reciprocating pistons al. The pistons in each bore together and move out together.

cams a portion of the rectilinear forcev is converted into a rotary motion of the rotor b.-

The rotor 6 is keyedto the shaft g, whose ends are journaled in the ends of the houslng a. On the left hand end of this shaft is a beveled pinion meshing with a beveled On the shaft of the beveled gear t are two cams y' engaging with the terminals ofl the rock arms Z which connect with the rock shafts m that in turn are fast to the rock levers n. rThese rocklevers n engage the ends of the valve stems o and serve to (not pair of pistons in each cross section on the line D-D push the valves oli from their seats as against the force of the springs p.

It will be noted that the housing a or the casting that forms this housing is cored out at q to form a wate1`-jacket to cool the parts adjacent the combus ion chambers. It will also be noted that the rotor is provided with two semi-annular grooves r at its mid portion, and that each semiannulargroove connects through the port s with thel combustion chamber. At opposite sides'of the hous` ing are ports t, the intake and the exhaust ports respectively, and these connect with suitable piping leading from the carbureter shown) and to the muiier (not shown). Only. one spark plug u is'requircd. and this can be set in a port at the top of the engine which will connect with the semi-annular aust port valve time. The ene points vof the timer -sending the current through the plug at that time. As the rotor continues around .the forward end of the semi-annular groove passes the exhaust port and the exhaust valve is opened by 'the valve mechanism and the burned gases allowed to escape.

rihe valve timing mechanism is the cams j second revolution of the rotor.

It will be noticed that4 'the pistons are coni nected up in pairs, one of the pair from one bore and the other of the pair from the other bore at the opposite en This is aecomplisned by the guide rods e', running longito govern the strokes of the pistons in con'- tudinally through the battery of cylinders nection with the action of the valves. i 55 and the arms y.
