' Application filed December 17. ms. Serial no. 137.2111.
Be it known that we, Jams Gnvasoo, a subject of the King of Italy, and Nroironas J.- GnvAoNAno, a citizen of the United States, residing at Brooklyn, inv the county ofKing's and State of New York, and ConnAn Anions-m, asulrject of the King of Italy, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Valve echanisms; and we do herehy' declare the following to he a full, clear,
and enact description or the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin s, and to characters of referenoe marked t ereon, which form a part or" this specification.
This invention has reference to improvements in valve-mechanism, and the present invention relates, more particularly, to a novel construction of three-way valve having means providing automatically for a return circulation of thefluid passed therethrough. The said valve-mechanism is adapted for many uses, but is particularly applicable for use in controlling the circulationof fluid in hydraulic presses, jacks, lifting devices and similar hydraulic mecha- .nisrns.
r The present invention has for its principal object to provide a very simple, cheap, effective and easily operated valve-mechanism adapted to control the alternate pas sage of a fluid through. the valve in one of I two directions with automatic means pe hitting the return circulation of the fluid through the valve to the source of supply, and also adapted to permit the direct passage of the fluid through the valve independently of the circulation means.
Other objects of this invention not at this time more especially mentioned will be clearly understood from the following detailed description of the invention.
The invention consists, primarily, in the novel valve-mechanism hereinafter more fully set forth; and, furthermore, this invention consists in the various arrangements and combinations of the parts, all of which will be more particularly described in the following embodied in t e clauses of the claim which are appendedto and which form an essential part off-his specification.
The lnvc'ntlon is clearly illustrated in the accompanyingdrawings, in which F e l is a view of a hydraulic press, the cylinder of which is shown in vertical section, and 'towhich is shown the applicationpf the novel valve-mechanism made according to and embodying the principles of the present invention, said valve-mechanism being shown in side elevation. Fig. 2 is a vertical longitudinal section of the novel valve rnechsnism'; Fig. 3 is a transverse section of the same, taken on line 3-3 in said Fig. 2, looking in thedirection of the arrow at; Fig. 4 is a view similar to said Fig. 3 showing the valve-mechanism arranged to control the flow of fluid in, one direction with a return circulation through the valve-mechanism; Fig. 5 is also a view similar to said Figs. 3 and 4 but showing the valve-mechanism arranged to control the flow of fluid in another direction also with a return circulation through the valvemechani'smj and Fig. 6 is a detail perspective view or a novel rotary valve-member employed in said novel valve mechanism.

The inner face of said cap-plateis provided with a centrally disposed cylindrical chamber or receiving socket 1), saidcap-plate be, ing further provided with a centrally disposed opening 11 communicating with the rear end of said chamber or receiving socket 10. Secured upon the outer face of said cap-plate in registration with said central opening 11 is an internally screw-threaded stuifing box member 12 connected with which is the externally screw-threaded stufling-box. cap 13. Connected with the side-walls of said valve casin 6 is a projection or exteng with a tubular passage 15 which provides an inlet opening communicating with said cylindrical chamber 7. Extending downwardlyfrom the rear wall 8 of said valve-casing is a projection or extension 16 provided with a tubular passage 17 which continues through said rear-wall 8 being so turned as to present its inlet mouth 18 in the inner face-of said rear wall in communication with said cylindrical chamber 7. Extending outwardly from one side of the rear wall 8 of said valve-casing is a projection or extension 19 provided with a tubular passage 20 which contlnues through said rear-wall 8 being so turned as to present its inlet mouth 21 in the inner face of said rear wall in communication with said cylindrical chamber 7. In like manner, extending outwardly from the other side of the rear wall 8 of said valve-casing is another projection or extension 22 provided with a tubular passage 23 which continues through said rear wall being so turnedas to present its inlet mouth 24 in the inner face of said rear wall in communication with said cylindrical'cham ber 7. A suitable pipe connection .25 is secured to said projection or extension 14, and the same being connected with a pump or suitable device which supplies the fluid, the latter is thereby delivered so as to be distributed and controlled by the Valve-mechanism. Connected with said projection or extension 16 is a pipe 26 which serves'to provide a return conduit for connecting said valve-mechanism with the source of supply from which the pump draws the fluid; Connected with the mice- .tion or extension 19 is a pipe 27 whic leads whi leads the fluid from another 0 said outlet parts of said valve-mechanism to thg cylinder 2 of the hydraulic press, the same being so connected with said cylinder as to introduce the fluid beneath said press-piston 3.

Said valve-memher is capable of rotary movements upon its central axis, as thus journaled, against the walls of said chamber. Centrallydisposed in the exposed face of said movable valvemember 29 is a receiving socket 30, the same being preferably of polygonal shape ,and serving to receive the engagement of the the projection or extension 22 is a pi e 28 coupling-head 310i .a spindle 32 by means of whichthe proper movements ofsaid valve-memberare produced, said couplinghead 31 having a polygonal shape corresponding to the shape of said receiving socket 30. Extending transversely through the body of said movable valve-member are a series of outlet ports comprising, an outlet port 33 which, upon a pro er movement of said valve-member, may e caused to register with said inlet mouth 21 of said passage 20- to provide an outlet-communication in one direction for the fluid passed into said chamber 7 through the inlet opening or passage 15; another outlet 'port 34 which, upon a proper movement of said valve-member, may be caused to register with said inlet mouth 2 1 of said passage 23 to provide an outlet communicatlon in another direction for the fluid passed into said chamber 7 through the inlet opening or passage 15;

Formed in the inner face of said rotary or movable valve-member 29 is a by-pass depression or cut-away portion 36, the same new 3 1': prevents communication between said by pass depression and said port 35. The said outlet ports 33, 34 and 35 are separated trom each other, as positioned with relation said cap-plate, is a holding collar 39. This holding collar 39 fits snugly and slidably within said cylindrical chamber or receiving socket 10 of said cap-plate 9. Formed in said cap-plate 9 is a duct or groove 40 which spindle 32 between said valve-member and conveys fluid from: the interior; of said chamher 7 into saidchamber or receiving socket l0 in back of said holding collar 39, and the fluid being under pressure as it is forced through the valve-mechanism transmits some of its pressure to said holding collar thereby forcing the same forward so as to cause the same to bear a ainst the exposed face of said valve-mom er 29 with sud:- cient pressure to hold the latter in proper bearing relation against the rear wall 8 of the valve-casing and thus preventing the fluid from flowing between such parts and causing their separation whereby a proper operation of the valvc mechanism would be prevented. Connected with the exterior end of said spindle 32 is a suitable handle or I lever member 41 whereby said spindle may beturncd to operate said-rotary valve-member 29.
The fluid enters the chamber 7 through f the inlet passage which is connected tof the pump for supplying said fluid. turning the valve-member 29 so as to register said directreturn port 35 with said inlet mouth 18 of the passage 17, the fluid may 5 he conducted directly back to the pump, or source of the supply, or elsewhere, since in this position the outlet ports 33 and3'4 are out of'registration with said passages 20: and 23, the latter being closed from communication with said chamber 7 by the inl terpos-ition of the body of said valve-member 29. By a further manipulation of said 5 valve-member 29 in onedirection said outlet 1 port 33 may be registered with the inlet mouth 21 of the passage 20, whereby the fluid is caused to enter said pipe 27 and is thereby delivered to said cylinder 2 above i the piston 3, the fluid so entering the cylinder causing a downward movement 03? said piston 3 and the parts connected therewith. 5
When said valve-member is in this position the said direct return port 35 is moved.

port 3d may be registered with the inlet mouth 24: of the passage 23, whereby the fluid trom said chamber 7 is caused to enter said pipe 28 and is thereby delivered to said cylinder 2 beneath said piston 3, the fluid so entering the cylinder causing an upward movement of said piston 3 and the parts connected therewith. When said valve is in this position said lay-pass depression 36 is so disposed as to straddle said inlet mouth 21 and said inlet mouth 18 so as to establish communication between the passages 20 and 1'27. This arra permits the fluid with the cylinder 2 above piston 3 to be driven out, by the ascending movement of said piston, through the pip .27., and through said passage 20, bypass depression and passage 1-7 into the return pipe 26, whereby the-fluid is returned to the source of supply. All of which is illustrated in Fig. 4: of the drawings. hi it is desired the said a crating handle or lever- ;41 may be connects by the link or connect,-
ing rod d2 to a pivoted lever d3 which is operated by contact with the push-piece id or press fioot 5 of the press to automatically turnsaid spindle 32, andthereby automatically operate said valve-member to altermtely cause the dew of fluid to be directed into the cylinder 2 upon opposite sides of the piston 3, all in a manner clearly to be understood irom an inspection of Fig. l of the drawings.
We are aware that some changes may be made in the arrangements and combinations f of the parts, as well as in the details of the construction of the same, without departing from the scope of this invention. Hence, we do not limit our invention to the exact arrangements and combinations of the parts as described in the foregoing specification and as illustrated in the accompanying drawings, nor do we confine ourselves tot-he exact details of the construction of the said parts.
