In 212) present invention the essential features lie in fihe peculiar correlation with the Working and pumping cylinders; in a novel construction of a combined valve and regulator mechanism, whereby by means of two sets of Working. and pumping cylinders, with a. sir valve mechanism, connnon bo all of the pumping and Working cylinders, I am encoleel. in a con'ipact and positive manner,

(l -C" designate the piston rods of the two working cylinders, both of which are connected. in a like manner with the crank shaft 100, the crank members 100 of which are set on quarters.

Each pump cylinder B-B has a port 5-5 at each end which ports alternately serve as inlets for a new ci'iargc from the feed pipe or valve, and as outlets for leading the charge from the puma cylinders to the ex iosicn ends of the worlringcylinders.

llhe piston rods D-D of the pumps are coupled up with the actuating mechanism that joins with the working piston in such manner that the pun] and working pistons at certain times trave in unison in the same direction, and at other times have differential movement, the reason for the latter being as follows; in the complete arrangement of one working cylinder and its co-acting pumping devices, the relation of the Workmg cylinder and its pump 1S such that the charge is forced out of the pump cylinder in ahead of its piston into the working cylinder back of the working piston under a low pressure. The pump piston is also'arranged to force the new charge into the working cylinder in the rear of the working piston under a pressure barely in excess of atmos'here so that the burned in iluum in tlv working cylinder will be allowed to escape to atmosphere, and dan-' ger of of charge in blowing out such rcsiluuin as might remain back ofthe pis ton is reduced to the minimum. The final pressure or force of the charge in front of the moving pump piston is exerted after the burn mixture permitted to escape through the exii, it port ot the working cylnider and the piston therein begins to recover the said exhaust. To provide for the unitary action, as also for the differential action of the two working and pumping pistons carried by the rods C-C, D-D', I join the piston rods C each to a cross head E,

slidablc on theirame section 0 and fulcrum a bell crank lever 20 to each cross head E and connect the short arm 20 of the respictive bell crank lever to the outer end of the respective pump piston rod D D, as the case may be, and connect the long arm of the respective lever 20 to the-respective crank member 1.00 of the crank shaft 100,

shown in the drawings, it being understood that the connection between the short arms 2i? and. the respective pump rods DD is made in such manner that the arc of movement of the arm 20 will not interfere with the movement of the respective pump rod TI -DZ as for example, by having the pivot pin carried hy the respective rod D ll" operate in a slot or elongated hole in respective ltior arm as shown in shaft I will make one revolution.

of i'nainifueiu're thc'valve designated generally by the reference character F, is disposed about centrally of the two sets of cylinders and 1S suitably supported so that the drive pinion f, on the pendent axle stem thereof will be in a plane with the crank shaft whereby to bring such pinion 7' into mesh. with a drive pinion g of the same size on a counter-shaft G, suitably mounted on and geared with unddcriving motion from the main or crank shaft through g and 100 so that the valve F is brought into direct connection with the crank shaft. The gears 100 and g are prcferabl Y of the same size it being understood that the size of the gears f, g' and 100 need not be the same but they should be, in practice, so proportioned that the s need of rotation of the valve shaft 7" will e the same as that of the crank shaft 100. In other words, after each revolution of the crank shaft 100 the valve The valve F comprises a fixedl held base portion 10 having four sets 0 ports arranged in the manner best shown in Figs. 6

the four sets of ports are disposed 90 :1 art and are designated respectively by the CRHI'. actors 1"1 Q Q 3"3 P -4, two of which, l1 and 3--3 are arranged to cooperate with one set of cylinders. and the other two, 2"--2 and 4 9, cooperate with the other set of cylinders.

Surrounding the member 13 and fixedly '90 and 7, by reference to which it will be seen held ,on the base 10 is a cap or housing 14 which projects over and. above the member- 13 and forms the mixing chamber into which the mixed and air discharge and from which the working agent escapes into the opening 13* of the rotary valve"mem'ber 13.
