rlhe object ol the invention is to provide e io new sind improved ges, gnsolenc, or the like explosion-engine :irrenged to utilize the expensive power oi the ens to the 'lnllest adventngc :ind to nllow running,` the engine with thc n'reetest econorny.

rlhe invention consists in the novel construction end combination of the severel pan-ts, ns will lhe hereiinilter fully set Vforth, end pointed ont in the cleinis.

ik practical embodiment of Iny invention is 2o represented in the nccoinpnnying drnwings, 'torinii'ig n part otl this specification, in which siniiler clinrncters el reference indicate corresponding parts in ell the views.

lhe explosion engine illustrated in the 30 drziwings is of the four-cycle type :ind is pro vided with three peirs of cylinders it A', ll lil', :nid C o1" which the cylinders fili, ll, end (l nre the hin'lnprcssnrc cylinijlers end the cylindifxrs ik', l, end (fl :tre the low-pressure cylinders. ln the peir of cylinders itY A reciprocnte the connected pistons l) ll, end siiniler pistons E E' reciprocate in the priiro'l cylinders ll ll, :ind like pistons l1` h" operai/tifa in the pnir of cylinders C il.

.lhe higlrpressure cylinders il, B, end U ere provided et their upper or working` ends with inletwelvos l l li, respectively, sind :ilse with citiieivist-mlves il il' JI, respectively, olil which the vzilite il is connected hy n, pipe li 50 with the upper or wnrltingl end ol the lowpressnre cylinder fly, the cxhenst-rnlve il ot the higlnprcssnrc :ylinder B is connected ley e pipe fici with the working,l end ol" the lowpressnre cylinder U', :ind the exhnnst-inilve 55 J2 et the high-pressure cylinder (l is connect* ed hy e pipe l(2 with the workinnl end of the low-pressure cyliinler il.

Freni the Vlforeggoinp,l it will he seen that the exlninst-relve ol'f the high-pressure cylinder 60 oi one pnir el cylinders is connected with the 'win'kiing end of the low-pressure cylinder ol another pair eli cylinders, se thnt the exhnnst ges Vlronn the high pressure cylinder ol one pnir oi cylinders cnn pnss into the low--pres- 65 snre cylinder of another peill et cylinders to work expninsively therein nnd press on the corresponding' low-pressnre-cylinder pistons D E liv, respectively, sind et the sinne time thc corresponding' l1ig'l1-pressnre piston is nt 7O the downward snction-strokelvhc workingI or npper ends of the low-pressure cylinders Ad, H, :ind C nre provided with exhenstwnlycs L, L', end if, respectively, end the inlet-velves l l l. l'or the several hinh- 75 pressn re cylinders nre controlleil hy snitnhle niechzinisin freni :i cn|n-slmllt N, :ind the c2-;- hnnstelves .l JA .lll L l] ,lf nre controlled hy snitnhle inechnnisrn lroin e cern-shaft 0, both fznn-shzifts lil and beingl driven hy n snit- SO nihle le'enrinn' l) 'from the mein crznik-shnlt l l.

, rlhe workinpfends oi the high-pressurecylinders rl, li, :ind (l :lire provided nlth the usuel igrnitinn' derice (llot shown.)

'lhc operation is ns `ollows: Then the seiYM 85 erel pnrts nre in the positioli :is ii'ii'liiiznted in the drnwiinirs, then the explosion hns leken pince in the npper end ot the highqiiri isere cylinder it, so thai-t the piston ll therein is forced downward hy the iorce oi" the explo 90 sion. ,lhe piston lil in the high-pressure cylinder il is now on its return orexhznist stroke, while the piston lll in the cylinder U is on its downwind er suction stroke, end the ,grises iroin the ijirevions explosion in the highpres- 95 sure cylinder .li now pnss troni this cylinder, by wey olE the fnlve il" :ind pipe li", into the cylindin il' to press en the piston l*V to nid the latter in its downward stroke, so that the eX- haust-gases from the high-pressure cylinder B are utilized in the low-pressure cylinder C' at the time the pistons F F are on the downward stroke, the piston F in addition being on its suction-stroke. Now when the piston I) is on its return or upward stroke the valve J opens and the gases from the previous explosion pass through the pipe K into the cylinder I3 to press on the piston E', so as to aid the latter in its downward stroke, as the piston E is now on its downward or suction stroke. At the time this takes place an eX- plosion occurs in the upper end of the cylinder C, so that the piston F is forced downward by the force or' the explosion, and when this piston is on the return stroke then the valve J:l opens to allow the gases to pass from the high-pressure cylinder (l, by way of the pipe K2, into the low-pressure cylinder A' to act on the piston F] therein when the latter is on the downstroke and its companion piston D is on the suction-stroke. Frein the foregoing it will be seen that while the piston in a highpressure cylinder is on the suction-stroke to draw in a fresh supply of gas its companion piston in the low-pressure cylinder is actuated on by the expansive force ot' the gases delivered into this low-pressure cylinder from the high-pressure cylinder ot' another pair of cylinders, and consequently the expansive Yforce or' the gases is utilized without requiring explosions in the low-pressure cylinders.

Itis understood that I do not limit myselt` to the number of pairs of cylinders shown and described, as the same may be varied and two or more than three pairs of cylinders may be used and connected with each other in the manner above described for producing the desired result.

It is understood that when the pistons D, E, and F' are on the return stroke during the compression period the corresponding eX- haust-valves L L L2 open to allow free exhaust of the gases from the working ends of the low-pressure cylinders A B C.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. An explosion-engine having pairs of cylinders, each pair consisting of a high-pressure cylinder and a low-pressure cylinder, the exhaust of the high-pressure cylinder in one pair of cylinders being connected with the lowpressure cylinder of another pair of cylinders at the time the high-pressure cylinder or' this last-mentioned pair of cylinders is on the suction-stroke.

2. An explosion-engine having pairs of cylinders, each pair consisting of a high-pressure cylinder and a low-pressure cylinder, the exhaust or' the high-pressure cylinder of one pair or' cylinders being connected with the pressure side of the low-pressure cylinder ot another pair of cylinders, the connections being such that the high-pressure cylinder of one pair of cylinders is connected with the low-pressure cylinder of another pair at the time the highpressure cylinder for the last-mentioned pair of cylinders is on the suction-stroke.

3. An explosion-engine having pairs of cylinders, each pair consisting of a high-pressure cylinder and a low-pressure cylinder, the exhaust of the high-pressure cylinder in one pair ol cylinders being connected with the pressure side ot' the low-pressure cylinder of another pair of cylinders, connected pistons 'for each pair or' cylinders, a crank-shaft having its cranks set at angles one to the other and connected with the said connected pistons, and valves controlled from the said crank-shaft and controlling the fiow of the gas from the high-pressure cylinders to the low-pressure cylinders.

et. An explosion-engine having pairs of cylinders, each pair consisting of a high-pressure cylinder and a low-pressure cylinder, the exhaust of the high-pressure cylinder in one pair of cylinders being connected with the pressure side of the low-pressure cylinder of another pair of cylinders, connected pistons for each pair of cylinders, a crank-shaft having its cranks set at angles one to the other and connected with the said connected pistons, valves controlled from the said crank-shaft and controlling the low of the gas from the highpressure cylinders to the low-pressure cylinders, and exhaust-valves for the low-pressure cylinders and controlled from the said crankshaft.

In testimony whereo't` I have signed my name to this specification in the presence of two subscribing witnesses.
