inFigs. 7 and 8 of the'drnwings. This'fl valve 16 is mounted fol rotating on the pis-"j ton 6, the valve 16 being sevured 0111 stud 17, which is join-milled in a bearing lSfi'nflj the "piston 7. To this stilil 1 there-isse f! eu'redn ratchet wheel 19,,whieh is engugbil i by 1. pawl 20, pi\"oted tothe under side of the piston, and held in.operativeposition There is also secured to this sti d jl'Tn'I-be ele(1 ge:i'1' ,wl1eel 22, with which meshes v bevel'ed" gear wheel 23, nonntml looselyen :1 pin .24 'mountedin the piston.

.Fig. 2 of the drawings shows the position of the valve at the firing stroke. Fig. 7 shows the position of thevalve at the'end of the firing stroke, andthe' commencement of the scavenger stroke. Fig. 8 shows the position of the valve at the end if the scavenger stroke and the commencement of the inlet stroke, and Fig. 9 shows the position of the valve at the commencement of the compression stroke. r

-It will be seen that the'valve 16- makes a one-quarter revolution with each coui-, plete rotation of the shaft 34, which is con nected with the piston rod 25, by means of the crank 35. This rotary movement of the piston 16 is obtained by means of the relative sizes of the

beveled gear wheels

22 and 23. The'piston rod'25 on the firing stroke shown in Fig. 2 of thedrawings rotates, by the means described, the beveled gear 23, sufiiciently far for this beveled gear 23 through the beveled gear 22, to rotate the stud 17, a distance sufficient to move the valve to the position shown in Fig. 7, at

which point the scavenger ports 33 in the valves 116 are in communication with the scavenger ports 7 and 8 in the pistons 6, these scavenger ports 7 and Sbeing elongated as'shown' in Figs. 7, 8 and 9 of the drawings. \Vith the pward movement of the piston 6 the dale 316 55 moved by the means described to the position shown in Fig. 8 0f the dra\vings',and with the downward or inlet stroke'of the engine, the valve 16 is moved from the position shown-in Fig. 8 of the drawings to this position shown in Fig. 9 of the drawings, at which point one .of the inlet ports 32- has been brought into engagement with the inlet port valve 30, permitting the explosive mixture to fiow therethrough, and into the cylinder, so that with the upwardmovement of the piston 0n the compression stroke the combustible mixture will be compressed to be fired in a manner readily understood. 1

In the two-cycle typeof engine, shown in Fig. 10 of the drawings, the pistorl 36 corresponds with the piston 6 shown in Fig.

1 of the drawings, and the inlet port 37 in the cylinder. the scavenger ports 38 and 39 in the cylinder and the scavenger ports 40 and in the piston eorrespondirig wit the simila inlet and ports shown in Fig. ,of, the drawings. The valve 45 has a rim 42, with a valve port, 45'. Thetwq-cycle ena'stud 43, which is jo r aled in the bear-- ing 44, in the piston 36, t e valYe 45 being secured to the upper end 'of the stud 43 and a beveled gear wheel 46 being secured to the lower end of the stud 43. This beveled gear wheel 46 is in mesh with a beveled ear wheel 47 secured for rotating at all times with the upper terminal .48 of the piston rod 49, which is articulated to the piston 36 in the customary manner. It will, therefore, be seen that with this construction the valve 41 will rock with the rotation of the shaft 50, and that it will not rotate in the gi'ne shown in Fig. 10 otxthe drhi'wings has 'w ,same direction intermittently, as is the case 45 will rotate to the position shown in Fig.-

12 of the drawings, when the scavenger ports 51 in the valve 45 will be in communication with the scavenger-ports40 and .41 III the piston 36", to permit a blast of air to flow through the ports 38, the port 40, one of the ports 5.1, through the cylinder to the port 51, through a. port 41, andv out ofthe ports 39. vThis will carry the "alve 45 as far asit will travel in one direction, and with the movement of the valve in the opposite direction it will be pawed to the po sition shown in Fig. 13 of the drawings, at which point the piston is at its lowermost position, to permit the admission of an explosive mixture through the port 37, and the valve port 45,-the valve 45 continuing to rotate in the last-mentioneddirection with the upward movement of the piston and with the compression of the combustible mixture so that when the piston has moved to its uppermost position the-ports 51 in the valve 45 will disposed as shown in Fig.- 11 of the drawings at which point the explosive mixture will be fired.
