Be it known that I, JAMES A. ARNOLD, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Valves, of which the following is a specification, reference being had therein to the accon'ipanying drawings, forming part of this specification, in which- Figure l is a view in side elevation of a glasshlowing machine adapted to be operated by fluid actuated mechanism and illustrating the application thereto of my improved controlling-valve. Fig. 2 is a similar view of the machine from the opposite side, showing the controlling-valve and its connections. Figs. 3, t, and are diagrammatic plan views of the controlling-valve, illustrating the handle of the same in the three successive positions of the pressing and lifting cylinders, respectively. Figs. 3, at, and 5 are cross-sectional diagrammatic views of the controlling-valve and connections therefrom to the pressingcylinder, showing the circulation thereto and the position of the valve and piston of such cylinder, respectively, corresponding to the positions of the valve-handle illustrated in Figs. 3, 4, and 5.

Fig. 7 is a transverse vertical section of the controllingvalve on an enlarged scale, the section being indicated by the line VII VII of Fig. 3 and in a position corresponding to the first position of the valve, as shown in Fig. 3. Fig. 8 is a similar View at right angles to Fig. '7, indicated by the line VIII VIII of Fig. 3, the position of the valve being the same. Fig. 9 is a similar view, indicated by the line IX IX of Fig. 3, the valve being still in the same position, the section illustrating the supply and exhaust connections, respectively. Fig. 10 is a detail perspective view of the valveplug. Fig. 11 is a sectional detail view of a portion of the valve, showing the bushing provided with a continuous common port. Fig.
12 is a similar view showing the valve-shell without the bushing, the port being made through the shell of the valve and the plug bearing directly therein.
My invention relates to the class of valves for controlling the flow of fluidas, for instance, to and from fluid-actuated mechanism, as steam, air, hydraulic, or other cylindersand is particularly designed for the pn rpose of controlling the supply and exhaust from two independentcylinders adapted to operate independently of but in relation to the operation of each other.
\Vhile the valve is adapted to be used with differentmechanisms and under varying conditions, I have, illustrated it as applied to a machine or apparatus for forming glass articles wherein the operations necessary in such work,\vhich has heretofore been accomplished manually or through various mechanical operations, are performed by means of compressed air or other suitable fluid-pressure.
Referring to the drawings, wherein such a machine is illustrated, 2 is the main frame or base, with which base is incorporated a central mast or column 4, around which rotates the blow-mold-supporting table 5, resting upon suitable bearings, preferably rolling bearings, supported upon the base 2,.suitable devices for rotating and locking the table in position being provided. The table is adapted to be rotated at fixed proportions of one revolution-as, for instance, one-third so that the blow-molds 47, mounted thereon, may be brought successively into position for the various steps of the operation.
Vertically arranged in alinement with each other in a suitable position upon the machine, preferably in front, are the blank molds 11 below and the plunger 12 above, both of which are vertically reciprocating and actuated by the lifting-cylinder 15 and the pressing-cylinder 20, respectively, and such blank-mold and plunger are so connected with the pistonrods of these cylinders as to be raised or lowered by them, so as to project the pressingmold upwardly through a suitable openingin the main frame and through the rotating table to receive the charge of moltenglass and also to lower the plunger 12, through the neckmolds in the press-mold, performing the pressing action within such molds and forcing the blank into the neck-mold in the usual way.
A represents my i mproved controlling-valve 5 for the purpose of regulating the supply of air to or the exhaust from cylinders and 20, the valve being located in convenient position on the side of the machine for operation by the workman. Such valve consists of an outer shell 23, provided with an interior bushing 24, within which is rotatably mounted a tapered plug 25, the stem 26 of which extends upwardly through a suitable stuffing-box and is provided with a handle 27. The plug is adjustably held in rotatable position within the bushing by means of any suitable supporting or bearing device, as a set-screw 28, against which a terminal stem 29 bears, leaving an annular space 30 around the lower end of the valve-plug, and other convenient or suitable mechanism for providing a bearing for the lower end of the plug may be substituted for the stem and set-screw and I do not wish to be confined to such device, as other substitution is obvious. Above the valveplug and within the bushing is a similar annular space 31, and by means of such annular space at each end free circulation of the supply and exhaust currents of air or other fluid around the entire inner area within the bushing is provided.
Regularly arranged at equal distances from each other around the shell or case 23 of the valve are inlet and outlet connections 32, 33, 34, and 35, while midway between the connections 32 and 35 are located a common supply-passage 36 and a common exhaustpassage 37, respectively. The supply-passage 36 communicates through the port 38 with the upper annular chamber 31, wherein a constant supply-pressure is maintained. The common exhaust-passage 37 communicates by port 39 with the annular exhaustohamber 30,from which exhaust-pressure may be taken at all times and preferably discharged through passage 37 to the atmosphere or by a pipe connection to any other suitable point of discharge. Each of the inlet and outlet passages 32, 33, 34, and 35, which are located about midway of the valveshell, communicates with the upper and lower ports 40 and 41 through the bushing and through such of the ports of the valve-plug 25 as are brought into register therewith with g; the annular chamber 31 and the lower annular exhaust-chamber 30. The plug 25 is provided at its upper peripheral portion with a recessed port 42, which covers one-quarter of its circumference and which is capable of io communication with any two of the adjacent supply-ports 40, while on the opposite side is a similarly-recessed port 43 of only sufficient width to communicate with any one of such ports. The lower peripheral surface of 5 the valve-plug 25 is provided with similar recessed ports 44 and 44, oppositely located to each other and of sufficient width to be maintained in independent register with two only of the exhaust-ports 41 and to maintain communication with such ports and throughout a one-eighth revolution of the plug, as indicated in the diagrammatic views on Sheet No. 2 of the drawings. As thus constructed this portion of the valve constitutes a doubleended plug by means of which communication may be had from the general supply to the particular supply-pipe leading from the valve-chamber, as desired, or from a particular exhaust-port leading from such particular pipe or others to the common exhaust-chamber 30 and from there to the atmosphere, as desired. By reason of such construction and arrangement of the various parts I am enabled to provide supply and exhaustcirculation for accomplishing the different operations of the machine, and it will be understood that the valve as so constructed is capable of all such combinations and arrangements as are clearly illustrated in the drawings, and the valve, while in its integrity is a single valve, is capable of performing the functions of both a supply and exhaust valve for the two cylinders within the scope of the single operation of it.
In the operation of pressing the glass in the press-mold 11 the glass is first placed in such pressing mold in its lowered position, as shown in Fig. 3, during which operation the mold is maintained in a lowered position by gravity, the valve A being in its normal initial position, as illustrated in Figs. 3, 3, and 3 of Sheet 2 of the drawings. The piston and connected plunger of the pressing-cylinder 20 are likewise maintained in a normally raised position, as shown, by air-pressure, and such positions of the two cylinders are maintained continuously until the valve is changed to the position shown in Figs. 4, 4, and 4". For the purpose of supplying pressure to and of exhausting air from the bottom cylinder 15 a pipe B B leads from valve connection 33 to the bottom of the bottom cylinder, while from connection 34 of the valve pipe T B leads to the top of the bottom cylinder. From connection 32 of the valve a pipe B T leads to the bottom of the top cylinder 20 and from connection 35 a pipe T T leads to the top of the top cylinder. When the valve is in the normal position (shown in Fig. 3) pressure will be established through such connections by way of ports 43 and 40 to the top of the piston 15, keeping the mold ll lowered and opening free exhaust from underneath the piston through connection 33, ports 41 and 44, chamber 30 and port 39, and the general exhaust-port 37. In a similar manner pressure is supplied by way of ports 42 and 40 through connection 32 and pipe B T to the lower side of the piston 19, keeping such piston and plunger raised, while exhaust from the upper side passes through pipe T T, ports 41 and 44 to the atmosphere. In the second operation of the valve, as illustrated in Figs. 4, 4, and 4", the mold 11 is raised by admitting pressure IIO through ports 42 and 40, connections 33, and pipe B B, exhaust being established through pipe T 13, connections 34, ports l1 and -il-l to annular chamber 30, and therefrom to the common outlet 37; but during such raising action of the mold 11 the plunger is still maintainedraised, such one-eighth movement of the valve continuing to maintain the original communication already described through the same ports by reason of the width of recessed ports 42 and 4%.
In the third position of the valve (shown in Figs. 5, 5, and 5 the mold-cylinder is still maintained in a raised position by reason of the continuation of the pressure com munication already established through ports l2 and 40, connections 33, and pipe 13 B, such movement of the valve, however, reversing the condition as to the top cylinder and admit ting pressure through ports 13 and 40, connections 35, and pipe T 'l to the top of piston 19, exhaust from underneath the piston passing outwardly from pipe B 'l, connec tions 32, ports 41 and 44: annular chamber and ports 39, and general exhaust-passage 37 to the atmosphere, by which operation the plunger 12 is lowered in the mold l1, perform ing the pressing action within such mold, l'orcing the blank into the neck-mold in the usual way. The valve is then reversed to the middle position, raising plunger 12, and upon further movement of the valve back to the first position the press-mold ll is lowered, leaving the blank suspended from the neckmold, or such operations may he performed simultaneously by at once turning the valve back or to the first position.
In Fig. 11 I have shown a modified construction in which the ports 40 and ii are merged into a common port of the same length as the inner vertical elongated openings of the pipe-openings 32, 34:, and 35, the solid portion of the plug between the upper ports 42 and 4:3 and the lower ports 44: and 44: providinga dividingabutment. In Fig. 12 I have shown a construction wherein the bushing is eliminated and the plug seated upon the inner faces of the valve-shell, which is of course turned or ground to a proper fitting seat. Such construction without the bushing will give good results and is less expensive, aud I do not desire, therefore, to limit the invention to either form exclusively.
It will be understood that the valve may be utilized to establish communication to and from cylinders adapted to operate in different relation as to time to each other by varying the location and proportions of the various ports or that other changes or variations may be made in the construction, design, proportions, or other details of construction by the skilled mechanic without departing from my invention, and I do not, therefore, wish to be limited to the exact construction shown and described, but to include as within the scope of the following claims all such changes, &c.
