2 108;
branches cominnicating with the water
chamber 13 at various points throughout
the length of the cylinder 11.
Each of the two pistons 14 is formed with
5 an internal water chamber 38, which com-
municates at one side of the piston with a
water inlet pipe 39, which is slid ably 1e-
ceived within one leg of a substamiially U-
shaped water pipe 40 conmuniati n g with
10 the adjacent end of the inlet manifold $6,
whereby water is conducted to the piston
during reciprocation thereof. A water outlet
pipe 39 is secured to the piston 14 and com-
minicates with the chamber 38 at i. point
15 diametrically opposite the pipe 39 and is slid-
ably and telescopically reeeived I one leg
of a substantially U-shaped pipe 40a having
connection with the water outlet mani-
fold 35.
20 In operation, the explosion of the mixture
occurs in the explosion chamber 14a, and act-
ing upon the opposed pistons 14 drive the lat-
ter outwardly, thus moving the crank shafts
16 in opposite directions. The movement of
25 one crank shaft is transmitted to the'other by
the rods 20 and the shafts are thus caused to
rotate in synchronism. The inlet andexhaust
valves 24 are-operated by the cams 25 of the
cam shaft 26, which latter is driven from
so the crank shaft 16 through the bevel gear
wheels 28, and the movement of the cam
shaft is transmitted to the shaft 3 of the
pump 34 by the bevel gear wheels 31 and
32, thus. causing the water to circulate
35 through the water chamber i3 in the cylin-
der, and also maintaining a thorough circu-
lation of water through the chambers 38
in the pistons 14.
What I claim is:
40 1. An engine comprising a base, a hori-zontal cylinder secured to said base, crank
shafts journaled to the ends of said base,
intermediate and outer cranks formed on
said shafts, bars connecting the outer cranks
of one shaft to the outer cranks of the 45
other shaft to cause said shafts to rotate
in synchronism, pistons movable in the cyl-
inder in opposite directions, and forming
a combustion chamber therebetween, means
connecting the pistons to the intermediate 5b
cranks, a double chamber secured to'the cyl-
inder and in communication with the in
terror by a pair of ports at a point between
the pistons, valves normally closing the
ports, a cam shaft driven by one of the s
crank shafts and journaled in the double
chamber, and a pair of cams on said cam
shaft within the double chamber to unseat
the valves.
2. An engine including a horizontal cylih= 66
der having a crank shaft at each end, pistons
movable in said cylinder in opposite direc-
tions, chambers formed in the iiterior of said
pistons, miahs connecting the pistils with
the crank shaft, a water' jacket surrounding 65
the cylinder, a pump associated with the
cylinder and driven by one of the crank
shafts, inlet and outlet pipes connecting the
pump with the water jacket, inlet and out-
let pipes connected to the chambers, of. the 70
pistons, and substantially U-shaped pipes
connecting the first and second naiiied inlet
and outlet pipes and adapted to telescopi-
cally receive the same.
In testimony whereof I affix my signature 75
in presence of two witnesses.
