To all whom it may concern: conveyingthe exhaust water away. from the Bc it known that I, Lewis C. Lewis, eitimotor, it being' understood that the llexibil zen of the United States, residing at Columity of the hose permits it to conform to the bus, in the county of Franklin and State of movement of the sleeve. l Ohio, have invented certain new and useful A horizontal wal 24 which is a portion of 60 Improvements in Water-Motors, of which the Hfshapcd mem 10, divides thepiston the following is a s lcciication. ntotwo c iambers, an u per chamber ..5 and M invention relates to water motors and a lower chamber 26., he plate 12, the leftA has fbr its object the provision of a device of hand cup leather 14' and the H-shaped niemthis character constructed in such manner ber is cut throu h to bring the passageway c5 that it may be very simply and consequently 22 into communication with 'the chamber 25 very cheaply manufactured, while operating and to bring the chamber 26 into communifully as well as devices of more expensive cation with the exhaust passage 27 which construction. -lies below the horizontal wall 20. If desired, Further ob'ects and advantag of the inthe wall 24 may be recessed as at 2S for the 70 volition will e set forth in the detailed dereccption of a gasket 29 andthe fmntedge of cri tion which now follows. the wall 20 may be reduced as at-'30, so that f 'l'lhe figure shown in the v'accompanying when the plate 18 is forced up aga-inst the" drawing ls a vertical section of a water motor plate 12 by the screws 13I this reduced vnd of constructed in accordance with the inventhe wall 20 will bear ergamst and expand the 75 tion. Easket 29 ,to form a water-tight connection 'Referring to the drawing, tlie numeral 5 etween the walls 20 and 24. Valve. seats 31 designates the cylinder of the water motor, and 32 are formed in the H-shsped member said cylinder being made from a length of and "elves 33 and 34 are adapted to engage z5 tubing. Heads 6 are screwed upon this cylthese seats.v These valves are mounted upon so' in'der as at 7 and these heads carry stullng. a valve .stem 35 which extends entirely xcs 8' and 9 of the usual and well known through the piston and is connected at its construction. Slidably dis )osed within the' outer ends to yokes 36 and 37 bv nuts 38; linder 5 is a piston whic 1 is composed of Openin s 39 and 40 are formed inthes'e so t e central substantially H-.sha ed member yokes, t le yoke-36 sliding upon thesleeve 19 ss 10 and plates 1l and l2, said p stes l1 and and the yokel 37`sliding upon the piston.. 12 beingsecured to the plates of the H-shaped rod 15. l member by screws 13 and said plates 11 and Ports 41 and 42 lead through the opposlte -12 serving to clamp cup leathers 14 between lsides of the piston from the "alveseats 31 themselves and the plates of thc H-shaped 'and 32, while ports 43 and 44 les-.l from the 9o member. .A piston rod -15 is threaded into a interior of the piston to valve seats -15 and 46. boss 16 of the )late'll asat 17. This iston These valve seats 45 and 46 are adapted to' f rod 16 exten through the' stullng x 9 be engaged by valves 47 and 4S, these latter and maybe connected ln any desired manner valves being mounted upon a stem 49, this also bolt a plate 18 to the plate- 12 and a to the yokes 36 and 37 b nuts 50- Spr' 0s .sleeve 19 is threaded into this plate. The 5l and 52 are supported om the faces of t e sleeve 19 extends through the stullng box 8 yokcs by recessed members 53.

and a horizontal wall 20 separates the upper The operation of the device is as follows:

thereof. the drawing, water enters thro "h the nip- -A nipple 2l sthreaded for the reception of ple 21 and passage 22 to the c mbe- 25, the coupling member of a. hose, not-shown, it passing from said-chamber through the rt being understood that a rubberor like'exi 42 to the ri rht hand end of the pasten w \ere ble hose is connected to this ni ple for the --it acts to drive the, piston toward the left. 105

. plrnose of conveying water un er pressure At this time the water from the lefthand'end the upper chamber or passageway 22 of of the iston is being exhausted through the the sleeve 19. A nozzle 23 is adapted to rt 4 chamber 26, passage 27 and nipple .A have thp coupling memberof a hose, not 3. When dur' the movement of the pis- '66 shown, connected thereto for the purpose of ton toward the le t, the spring 5l strikes'th'e 110 1 left bend head of the cylinder said spring `will be first slightly eom resse to store up powr. and then :ift-er tie 'compression of this sprin" has reached, a given point. the spring`will` act to throw the -valves and the yokvs quickly toward the iight. This will sont the valve. 3-1 and unseat tlie valve 33 and will sont the valve 47 and will unseat the' valve 4S. Water will then pass from the chamber 25 to the left hand end of the piston to drive the piston toward the rightandthe water ,at the right hand end of the piston will pass through the. peilt 44 to the chamber 26,A

then out of the passage 27 and the nip )le 23. The outlet through the nipple 23 is of s ightly greater area than the inlet tliwugh the nip'- ple 21, to prevent back pressure.

I am aware of the fact that valves of this -eharacter have been mounted in a movable piston and I do not bioadlclaim this struc; tui-e, but I a'm not aware t iat a; sleeve 1.9 divided by a horizontal wall inta two se arate passages in the manner shown, where y the water may both be conducted 'to the motor -and from the motor through a single tube,

has everbeen employed.

I therefore claim:

In a water motor, the combination with a piston having a transversew all which divides said piston into two chambers, 'said piston having ports formed throuvh the-walls thereof, of valves controlling the tlowof liquid through said ports, a ey inderiiiwhich said in said i piston is slidably disposed, a,tubnlar member which passes throng i one end of said e ilinder and is uonneeted tosnid piston a wal which divides said tubular member longitudmally mto an inlet passage an( exhaust passage,

said tubuhiijmembvr beingcloscd at its outer end, a nipple adapted t0 have aflexible con# duc-tor connected thereto, said nipple sei-vin 'to conduct- Iluid to the inlet passage, a secon nipple also adapted to have a flexible con-- ductor secured thereto, there being a port formed through the second nip le for the com ducting of fluid from the ex aust lissage, the outlet throughsaid second iiippl3 of greater area than the inlet 'through .the

first named nipple, the iilet pessageeoniiu.-

nicatinv with one of the chambers of the piston and the outlet assa, c conuiun'ieatmg with the other clianiier o the piston, there being a groove formed in the edge of the transverse wall, a conducting member seated wall of t e tubular member being reduced to 4enter said groove, and means for binding e 'being oove, the free edge of the'divided' said tubular member tightlyagainst said piston.. l In testimony whereof I alli): niysignatm'e in presence of two witnesses.
