centers, there are preferably a greater number of pistons? carried by the drum than chambers 8 in the shell, and in the present instance our pistons and 55 three chambers are provided. A spring pressed-partil tion 10 is mounted upon theshell l'between 'each pair -oi the chambers 8 and normally bearsvagainst thepe.-l
ripheryof the d rum 5 Boas to prevent the steam from passing from one chamber to the next adjacent cham- 60 berl i if A A pair of recesses 1 1' and 12 is formed inthe between each of the p istos, the saidrecesses being. i
spaced radially from each other, and .theseveralinner recesses 12 beingarranged in one'concentric'circle--ti while the outer recesses 11 are arranged vin a second con-` centric circle.' The outer 11,9f each pair coml municates upon one side'withone `of the openings by 'meansof the duct 13 while the inner recess 12 comf municates with the. opening 6 by means of a' similar 70 duct-14. Channelsl 15 and 16 are formed in oppositefaes of the pistons 7, one of th'echannels 15 beingdesigned'toeetablish communication with the inner recess12through the medium of the duct- 14 ivl 1il e vthe opposite channel 75 16 communicates with the outer recess. 11 fthroiigh the duct 13. Owing to the fact that the vchannels 15 and 16 have their mouths located upon opposite sides; oith'e' pistons itwi-ll be readily apparent that when livesteam 1 Ais admitted to the recessesllthe recesses l2 are thrown 8.0 into communication with the exhaust, .the live steam will pass into the chambers 8 through the channels 15 and will expand against one sident the .pistons-7 while r the dead steam upon the opposite side of the pistons `will pass into the exhaust through the channels 16. By 85 reversing this condition and usingthe outer recesses 11 as exhausts and delivering live steam to the inner recesses it will be readily apparent that the drum will he caused to rotate in the opposite direction.
lhe end 3 of the shell 1 is in the nature gf a valve 970,
ing and is shown as comprising the t w o sections l 7. and 18 in closing a steam space 1 9 to which theeteam or other fluid utilized for motive power is admitted through the inlet 20. The section 17 o f the valve casingiits closely against one end of the drum 5 so as to close the recesses 95 Il and l2. This section l7 is provided with a plurality of puirs of openings', the inner openings 2l being disposed in a concentric `circle corresponding to the inner i recesses l2 in the drum 5 while the outer lopenings22 are disposed in a second concentric circle correspon I to the outer recesses l l. The central portion of tlition l7 of the valvo'casing is formed with an annularex haust chamber 23 communicating with thelexhaust passage 24 and also provided with a plurality of slots 25,
I there being one of the said slots for each set of openings 5 of the casing while it is held spaced from the section 18 by means of a collar or annular rib 27. A plurality of openings 21,and22 in the 17 of the vnlve casing is formed in thel valve member 26. and radially elongated depressions 29 nre located intermedite of the slots 28. The rotary' movement of the valve 'member 26 is limited by means of o-,lug 30 operating within a cut away portion 31 of the vulveV casing and the said valve member is designed to be operated through the medium 'of a. rod 32 passingthrough a suitable stuiing box 33 and loosely connected to the said Avalve member by any suitable means, although it is preferred that the inner end oi therod 32 be formed with a laternlly elongated eye loosely receiving'a stud 34 upon the valve 26V.
I, The openings 28 and depressions 29 in the valve member are so arranged that when the valve has been moved to one of `its limits the openings 28 communicate with the inner openings 21 sind the depressions 29 communicate with the outer openings 22, while this condition is exactly reversed'nt the opposite limit oi `the movement of the valve member. It may be here mentioned that the depressions 29 are nl wziysincommunicetion with the annular exhaust chamber 23 through the medium of their respective slots 25- end serve to receive the exi 8:0 haust from either the openings 2O or the openings 22 according to the position of the valve. From the foregoing description it will be readily apparent that when the valve member 26 is `in such a'position thatthe outer openings 22 oi the section 17 oi the 85 valve casing receive live steo'm through the 'openings 28 and the inner openings 21 communicate with 'the exhaust, the said live steam will be delivered into the outer-recesses 11 ofthe drum 5 and will pass through the ducts 13 and channels 15 so :is to expand against one 40 side of the pistons 7', the dead steam upon the opposite side ofthe said. pistons being exhausted through the inner recesses 12 ond depressions i8 in the volvo member. -Upon moving the valve to its opposite position the in# 'ner recesses l2 in the drum receive live stcmn through the. openings 28 while thc outer recesses ilV communicote with the exhoustthrough the depressions 29, und
the motion of the drum is reversed in direction.
