To all whom it may concem:

in it l-znown that l, llonnn'r E'xCAnn, :1

citizen off'tho llnilod B'rales residing at (lxford, Ohio havo invonled a new and useful lin1 roveu1cnt in Valvc-Operating lllechan; ism, ol which lhc following is 21- Spooii'icalion.

My invenlion relates to valve operating mechanism adaplod lo hydraulic motors and lhc oli iecls of my i1111n'ove11'1on'ls are to pro vide 1111111119 for utilizing lhe pressuro oi. tho w nter shifting; for the valve after it is 1111 sealed; lo provide 111021115 for closing tho inlet port during lhc unsoaling of lhe valve; l'o providcnioai'ls for simultaneously closinglho inlet port and unseat-h1g the valve; to provido 1110:1115 .lor nnneating and for shifting; lhe valves of a hydraulic motor without lhc noeossiiy of using a spring or olhor elastic or resilient rueniher, and to provide such fOlll'l of construction and assemhlago of lho respootivo inletand disehar 1: p:

In ope ration, she cup packings are H1OV ahlc with the lovers allernalcly into contact with the corresponding ends of the valves. The elosnreo contact with the bosses on the inlet valve and the longer lower-portion of tho lOVOlS wii'lr the, ends of l-hodisehargo valvo as shown in Fig. 2. -'lhc greater cxerl-ion of tho shifting lever on the inlet valve nnsoats it from the left-hand port, as shown in F 3 but the, flow of Water lherounder and through thosaid lcfoliand port or chamber momentarily preventod by the closure, The further shifting of the valve to eloso the right-hand port 4 apparently due to the suction effect of the, valor acting upon the leiohand portion oi. the valve, during the remainder of the period of flow through the right-hand port. Upon the seating of lho valve abtho right. hand port, the water isuos through the lefl hand port and forces l-ho closure with the top of the lover in an outward direction for both unseating ind shifting the discharge valve with the lower end of the lovoryas shown in F l. he direl'wl ion of movcment oi. lho piston lJeLi 1g lhnrovoseel, the.
