I rod 37 and the ears 38 as will be readily" 42, this belng rendered Mounted preferabl in the upper or supporting section 8 oft e crank case is a valve operating shaft 29, shown. in Fig. 1 as turning in the bearings 3O. This shift may be rotated by the .crank shaft at half the speed of said crankshaft, by any suitable.

gearing which gives it. one revolution for ever two revolutions o In t 'e'present instance this gearing includes the s rocket 31 on the shaft 29 and the sproc et 32 on the crank shaft, the former sprocket having twice as many teeth as the' latter, and a chain 33 operatively connects the sprockets. .A forward extension34bn the supporting section of the crank case forms-a housing for the sprockets and chain, and the front end of this housing is closed by a'removable cover 35 as will be clearly understood. l i I I The valves ofthe separate cylinders are operated successively by means of eccentrics on the valve shaft through connecting rods 37. The method of actuating the eight sleeves from six eccentrics is illustrated in Figs. 1 and 2 of the drawings and by referring thereto it will be seen that the cocentric 36 reciprbcates the inner sleeve 23 of cylinder No. 1 through the connecting rod 37 which extends between said eccentric 36 and the cars 38 on the enlarged lower end 39 of said sleeve 23, the'pin 4-0 passing through the upper end or" said connecting understood. The eccentric 41-1'eciprocates the outer sleeve 26 of cylinder No. 1 and the inner sleeve 230i 0 linder No. 2 through the connecting rod The eccentric 42 reciprocates, the outer sleeve, 26 of cylinder No. 2 through its connecting-rod 37. Thus the four sleeves of cylinders 1 and'2 are actuated by the three eccentrics'36, 41' and ossihle by the fact that the outer sleeve 2t? of cylinder No. 1 'and the inner sleeve 23 of cylinder No. 2

i move coincidently. Also it will be'noticed that the cars 38 on the outer sleeves of cyl-" inders l and 2 are dropped down slightly below the lower edge of the sleeves, and this.

is necessary in the case of the outer sleeve of cylinder No. 1 to provide forits conne'ction with the connecting rod 37 by the same pin 40 that connects said rod with the inner sleehe 23 of. cylinder No. 2. In the case of cylinder No. 2.it is desirable since it makes it possible to have all of the connecting rods 37 of'th'e same .length, which of course is a distinct advantage in manufacturing.-

The arrangement of "the eccentrics and sleeves of cylinders 3 and 4 is identica'lwith that of cylinders 1 and 2 except that the parts are shown in opposite phase with cylinder Ed 4 leading. Thus the outer sleeve 26 of cylinder N0. 3-is reciprocated through its connecting rod 37 by the eccentric 43;

motor. vehicle construction at the present time are designed to' be startedby hand, that'is, the first turn of the crank shaft is given by the operator to start the motor on its proper c. ole-of operation. ,In the largermotors of "t 's character some diflioul'ty is thus turning the crank shaft by ha'n variogsf' devices llila've lll eretoforl-p been designe' or partia y re e E g t e compression stroke of the pistongpl n a four-stroke "cycle motor it is of course desirable that the.

cylindehr be open to the atmosphere'to relieve t e pressure during a part of the compression stroke of the piston and not during the entire period "of this stroke even in' cranking, and during all .of the other strokes of the piston it should be closed, Ifya pet cock is employed in the head of the cylinder for the purpose of relieving the compres-' 'sion, this pet cock must also remain open ,duringthe intake of the motor and thus considerable air is drawn into the cylinder 1 which rarefies the mixture and increases the difliculty of starting. Moreover, the com pression istoo much relieved for the reason that the pet-cock remains open during the entire compressionstroke. The ideal situa- 1 tion'therefore is the provision of a separate experienced in compressing the charge by valve which shall be opened during a partonly ofthe compressionsstroke of the piston, and in the present invention such a device is embodied, which device will nowbede- 1 scribed. I a.

Referring particularly to'Figs. 1 and 2, it will be noted that the inner sleeve '23 is provided i'none side with a port 46 and that the outer. sleeve 26 has a'similar .port 1 47, and these ports are so arranged that they will overlap or be in ,re 'ster during a part of the compression stro e of the piston. -They. are shown so in register in Fig.

cylinder and adapted v 3. In the side of the to register with the ports 46 and 47,-.;when

This is 2 early siown in F 6. Referring to Figs. '7 end 8. -which show i v another term of motor and in which the closed simultaneous section shown in Figs. 7 and 8 is taken at "I i-i. The valves 1 9 may niso an angle of to acenter line running of a shifting rod along the cylinders; the cylinder, the valve sleeves and the cylinder head 17 and its inwardly extendii a central portion 19 are o the some eon motion and are indicated by the smno reference characters as in Figs. l'to 5 inclusive. Each of the cylindei' Wells is provided with a port 53 which is eonnested branch pipe 80 to a main motive fluid supply pipe or conduit 81 in eominnnication with it motive fluid tank 60, pipe 81 having; therein a Yaive 61. The head is pro videcl with port or passage 82 registering the period with the port 53, anti with 21 passage 83 in owei' dead communication with the interior of the cyl- "101.- wheie incler. The passages 82 and 83 extend I ntei' of the longitudinally oi the head and are connecth'esents the ed to a valveveosing 84-, the valve easing ton is o he next lower heing serene 7 directly into the cylinder gi'esents the head at the passage 83, While the connec- 30 i the impel? {lead oi) e line tion to the passage. 82 is made by means of suitable pipe connections 85. The valve casing 84 isprovided with a ground valve 86 which is arranged to connect and close the passages 82 and 83. Each of the valves 86 is preferably provided with an arm 87, which is connected to a shifting rod 63.

' The valve sleees are provided with 'ports 51 and 52 which are arranged to register with the ports or passages 53and 82 in the cylinder wall and head respectively.

- being screwed into the cylinder head directly above the passage 91, while the contending along the cylindersand similar to nection between the valve casing and the ,passage 90 is-made by suitable pipe connections 93. The valve casing is provided with a ground three-way valve 94: which is arranged to connect and close the passages 90 and- 91. Each of'the valves 94- is provided with an arm 95 which may be suitably connected with the single shifting rod exthat shown at 65, Fig. 5. The valve sleeves are provided with suitable ports 46 and 47 which are arranged at certaintimes to register with the ports'lS. and 90, in the cylinder wall and head respectively. The

' valve casing 92 extends upwardly so as to form a cup 96 and is bored as shown at 97, :so that when the three-way valve is moved through 90 from the position shown in Fig. 9, a continuous passage will be formed by the passage 91, the valve, and the pas sage 97.

The operation of the starting arrange ment and. the compression relief is similar to that shown ni the firstforim This construction in which the ports are located Too above the lower edge of the downwardly projecting portion 19 of the "cylinder head has, however many advantages over the first construction, shown in Figs. 1 to 5 inclusive. In the first construction; where'the ports are located below the cylinder head, it is found th'at' leakage takes place in view of the fact thatthe cylinder and valve ports will be exposed to the interior of the cylinder. B y means of the construction shown.

in Figs. 7, 8, and 9, however, the starting and compression ports, both in'the cylinder waills'and valve sleeves,-are located above the lower edge of the downwardly extending portion 19 and above the piston ring 98, and between this piston ring 98 and a series The cylinder head is and resulting in cheapness of manu trolled by the shifting rod 63.

of other piston rings 99. A tight joint will therefore be formed, preventing leakage. The communication between the passages in the cylinder head is made by means of valves 86 and 92 which can be accurately ground and therefore a close fit can be obtained whereby leakage is prevented. It will thus be seen that all the passages from and to the interior of the cylinder are closed either by packing rings, or by ground joints, and therefore an air and gas tight construc tion is obtained.

In the construction shown in Figs. 1 to 5 inclusive, the connections are necessarily made in the sides of the cylinder walls, where they are inaccessible but in the con: struction shown in Figs. 8, and 9, the manually controlled valves are placed on the cylinder heads and thegreater part of the connections in case of the starting mechanism, and all of the connections in case of the compression relief mechanism,'are made in the cylinder head and its downwardly extending portion, permitting easy inslpection acture.

The m otor may be primed by pouring some gasolene into the cup 96 and moving the three-way valve so as to connect passages 91 and 97 Another advantage of this arrangement is that a wire or rod may be inserted through the passages 91 and 97, when they are placed in communication, so

that the cated.

The invention may be used to advantage in connection with multicylinder engines as in this type of engine, since there are a number of impulses during a revolution. In a position of the piston may be lomulticylinder engine the valves act as dis tributers to distribute the starting fluid to the cylinders in succession;

The motive fluid in the tank may be re-' plenished by an .air pump driven from the engine or operated in anyv other suitable manner; or the'valves 61' and 62 in Fig. 5, and 61 and 86 in Fig. 7, may be opened for a short time when the engine is in operation, so that a part of the exploded gases in the cylinders will be compressed in the tank.

In the latter case the gases, although .inert, are not detrimental to the operation of the motor, since the compressed gases are admitted during the explosion stroke only and are subsequentl exhausted, before a fresh .co'mbustibleis rawn in during the suction stroke. lVhere a motor is used in motor vehicles, the handles 63 and 64 preferably extend up to the vehicle dash so that they may be readily operated by the driver. The valve 61 is merely used-to permanently cut off the connection between the tank 60 and the pipe 58, but ordinarily this valve will be open and the connection1between the ports 53 and 53 and the tank will. be .con-
