Claims. (Cl. IS7-552.5)

This invention relates to distributing valves and more particularly to a permutation valve for serving fluid to ports of differing assigned value or identity.

The invention herein contemplates the use of apertured slides for separating a uid supply manifold from independent valued ports and for communicating any particular one of suchports therewith upon predetermined setting of a selected one or group of such apertured slides. In this connection the invention broadly embraces a port selection valve based upon the permutation bar principle.

It is aV further object of this invention to provide in a port selection valve a plurality of slides apertured in accordance with a pattern based upon binary numbers and correlated for serving fluid to a preselected column or passage.y In this connection each binary slide is provided with bi-pass or valueless apertures as well as valued aperturesL serving a particular column with which it is associated only when selectively registered with such column. This object further contemplates the provision of correlated series of binary valued apertures on adjacent` slides for serving a column having a value corresponding to the compound value of all binary slides selected.

Briefly stated, this invention contemplates the provision of a selection valve including a plurality of adjoining memberseach movable between two positions to serve one or another independent porteither alone or when moved conjointly with one or more of the other adjoining members..

Y lt is another. object of` this invention to provide a port selectiony valvein which each binary slide presents a valued aperture to a column` in which such binary Value is essential either alone or when compounded with one or more other binary values tomake up a'valve opening at a column corresponding in number to the total value of such single or compounded binary values.

These and other objectsV and advantages of thev present invention will become more apparent from aV reading of the followingdescription inthe light of the drawings in which:

Fig. 1 `is a fragmentary view, partly in plan view and partly in horizontal. section through a valve embodying the present invention, a limit stop member being broken away;

Fig. 2. is a sectional view taken substantially alongy line 2-.2 of Fig. 1, the limit stop member being shown.

Fig. 3 is atransverse sectionthrough Fig. 1 taken along line 33 thereof (as well as of Figs. 4 and 5).

Fig 4 isan exploded perspective view of a plurality of permutated binary slides embodied in the illustrations of Figs. l through 3. l

Fig. 5` isa rschematic chart in which a plurality of permutation slides are laid out inplan position relative to each other to illustrate the cooperation thereof with each other VforV selecting a port or column of predetermined value.

Fig. 6 is a modified arrangement of relatively movable members embodying the present invention.

2,904,070 Patented Sept. 15, 1959 ICC Fig. 7 is another form of structure embodying the principle of this invention.

The valve structure is generally designated l0 in the drawings. It includes a casing 11 providing a manifold 12 and a guideway 13 separated by one side wall 14 of the casing. The guideway 13 has a plate 15 in spaced parallel relation with respect to the side wall 14 of the casing. Both the wall 14 and the plate 15 are provided with sets of aligned outlet ports 17-17 each set being equally spaced from the next successive set thereof.

Each outlet port 17 on the outer plate 15 is preferably in the form of a nipple suitable for sealed connection to a conduit or tube 18 in turn communicating with some instrumentality (not shown) to be operated by fluid under pressure; Each set of outlet ports 17-17 constitutes the upper and lower end respectively of a column C bearing a particular numerical value, begin-ning adjacent one end of the casing and increasing digitally, i.e., by ones in succession toward the other end of the casing. Thus the first set of outlet ports 17-17 comprise the upper and lower ends of column No. l, the next set of ports 17-17 are in column No. 2 and so on upward. By column in this specification and in the claims is meant the passage which becomes formed by the ports 17-17 through the intervening passages of the interposed valve members, hereinafter to be described.

From the foregoing it will be seen that the manifold 12. is adapted to serve independent consecutively numbered columnar ports, In this manner fluid under pressure flowing from the manifold 12 through any one column C will effect operation of a preselected pressure sensitive instrument at the other end of the tube 18 communicated with such column. However, flow of fluid under pressure from the manifold to the outlet port or nipple 17 of all of the columns C is normally' blocked by a valve arrangement 19 embodying the present invention now to be explained.

The valve arrangement 19 as illustrated in the drawings comprises -a plurality of independent valve members, here shown as slides 20 each arranged for sliding movement either independently of the others, in bank with the others, or with preselected ones of the others, between an In and an Out position within the guideway 13 and relative to the casing 11. The valve arrangement 19 thus comprises a block of independently movable laminar slides 20. Each separate slide 20 is a at metal plate in which vapertures are formed in a position to register with one or another of the columns C defined bythe sets of outlet ports17-17' formed in the casing and outer plate 15, respectively.

It should here be noted that the present invention can be embodied in various structural arrangements as for example the coaxially arranged components as illustrated in Fig. 6 or in the alternative, the bar type slides as depicted in Fig. 7.

In accordance with the presentk invention, the apertured` slides 20 may be represented by numbers increasing in accordance with the binary system, for example, 0, 1, 2, 4, 8, 16, etc. The first slide, represented as Zero (0) in the drawings, is a gate or master slide. In this connection it `will be noted that the first or gate slide 0 has apertures 21 corresponding in number and spacing with the outlet ports 17 in Wall 14 so as to register with all columns C when slide 0 is in Out position. Contrariwise, when gate slide 0 is at In position, all of its apertures 21 are out of register with all columns C, Le., offset relative to their respective columns C. Thus it will be seen that no fluid can flow from the manifold 12 to the balance of the binary numbered slides until the gate slide 20 is moved to Out position.

The balance' of the slides 20 are considered binary slides, the first of which is represented as binary slide number one (1); the second as binary slide number two (2); the third as binary slide number four (4); the fourth as binary slide number eight (8) and so on up the binary scale. See for example the diagram Fi 5.

gEach binary numbered slide 20 has two different series of apertures formed therethrough, one series consisting of valued apertures 22 and the other series consisting of passage apertures 23. All passage apertures 2:3 on all binary slides 20 are disposed to align with their respective column C when such slides are in ineffective or In position. The valued apertures 22 in all binary slides 20 are offset relative to their respective column C when such slides are in normal or In position but so disposed as to become aligned with their respective column C when the slide in which they are formed is shifted to Out position.

For purposes of this explanation, the In position will be considered the ineffective position or that in which any valued aperture is offset or out of registration with its related column C. Alternatively, the Out position will be considered the effective position or that in which any slide is positioned for operatively registering each valued aperture therein with its related column C. In this connection it will be noted that all passage apertures 23 become misaligned or offset relative to their related columns when the slide on which they are formed is shifted to effective or Out position.

Each binary slide has its passage apertures 23 and its valued apertures 22 arranged in a pattern peculiar to its status in the binary system. Considering iirst the disposition of the valued apertures, each binary slide has its iirst valued aperture registerable with the column C corresponding in value with the number of such binary slide. In addition thereto each such slide has successive valued apertures related to successive columns up to but not including the next column corresponding in value to the next binary number, for example, binary slide No. 1 has its first valued aperture related to column No. 1 but none related to column No. 2. Binary slide No. 2 has its first valued aperture related to column No. 2 and a successive valued aperture related to column No. 3 but none related to column No. 4. Binary slide No. 4 has its rst valued aperture related to column No. 4 and its next successive valued apertures related to columns Nos. 5, 6 and 7, respectively, but none at column No. 8. Binary slide No. 8 has its rst valued aperture related to column No. 8 and its next successive valued apertures related to columns Nos. 9, 10, 11, 12, 13, 14 and l5 but none at column No. 16. This same pattern is repeated on each successive binary slide as illustrated diagrammatically in Fig. of the accompanying drawings.

In addition to the foregoing each binary slide has successive sets of valued apertures, the iii-st of each said additional set commencing with the second half of the preceding series of valued apertures` on the next higher numbered binary slide. In other words, binary slide No. 1 has the first of its next series of valued apertures adapted to register with the second valued aperture in the first series thereof on binary slide No. 2 as follows:

Binary slide No. 1 1

1 Binary slide N o` 2 2 2 Column number= 1 2 3 Binary slide No. 1 1 1 Binary Slide N o. 2 2 2 Binary Slide No. 4 4 4 4 4 Columnnumber= 4 5 6 7 Binary slide No. 4 has the first of its next series of valued apertures adapted to register with the fth valued Co1umnnumber= 8 9 10 11 l2 13 14 The foregoing spacing of each successive series of valued apertures repeats on each binary slide for compounding its binary value with that of another binary slide or slides. Thus it will be seen that binary slide No. 1 has a valued aperture worth 1 associated with every odd numbered column C. Binary slide No. 2 has a valued aperture worth 2 associated with all columns C where the value 2 is necessary to the making up of a valve opening at such columns. In other words, binary slide No, 2 has valued apertures in sets of two, first at columns 2 and 3, skipping the next two columns (4 and 5), then adjacent the next two columns (6 and 7) and so on. Binary slide No. 4 has valued apertures in sets of four one at each of columns 4, 5, 6 and 7, skipping the next four columns (8, 9, 10 and 11) then at the next four columns (12, 13, 14 and l5) and so on. Binary slide No. 8 has valued apertures in sets of eight, one at each of columns 8 to 15 inclusive, skipping the next eight columns (16 to 23 inclusive) then -at the next eight columns (24 to 31) and so on.

From the foregoing, and from the schematic chart comprising Fig. 5, it will be seen that the arrangement of the valued passages of each valve member (slide) relative to the columns is related to the binary designation of that member as follows: a member whose binary designation is x, when moved into the actuated position, i.e., the effective or Out position in the illustrated embodiments of the invention has valued passages so positioned and located as to be in alignment only with columns designated by the series x through (2x-l); 3x through (4x-1); 5x through (6x-1); 7x through (8x-1) etc. Thus, for example, considering the member having the binary designation 8, which is shown in Fig. 4 in the actuated, effective or Out position, it will be observed from Fig. 5 that the valued passages 23 of this member -will be aligned only with the columns designated 8 through 15, i.e., x through 2x-1, 24 through l, i.e., 3x through 4x-1; 40 through 47, i.e., 5x through xetc.

Briefly stated, it may be said that each binary slide presents a valued aperture 22 to a column C in which such binary value is essential either `alone or when compounded with one or more other binary values to make up a valve opening at a column corresponding in number wailth the total value of such single or compounded binary v ues.

From the foregoing it will be appreciated that with but four binary slides provided with valued apertures as explained above, it is possible to serve any one of fteen of the columns C. A fth slide, binary slide No. 16, provided with valued apertures in accordance with the foregoing pattern, and in conjunction with the preceding binary slides extended will serve up to 31 columns C and so on up the binary scale as is well illustrated diagrammatically in Fig. 5.

For purposes of clarity and to distingush all valued apertures from the passage apertures in Fig. 5, only the valued apertures 22 are shown as circles while each passage aperture 23, although identical to a valued aperture, 1s represented by a dot. In this connection it will be noted that no passage aperture 23 (dot in Fig. 5) is provided on any one slide at a column adapted to be served by any one valued aperture in such slide. Thus it will be appreciated that all columns C are normally closed when all binary slides 20 are in ineffective or In position. However, when any particular binary slide is shifted to Out position all of its valued apertures become registered with those columns with which they are associated.

Thus it will be seen that if only one binary slide is shifted only that column C corresponding to the binary value of such slide will be opened to serve fluid under pressure to its tube 18'. By the same token, should any other binary slide also be shifted to Out position the column corresponding to the binary value of said one slide Will be closed, and a valued aperture corresponding to the value of such other slide wdll be registered with a column C which already has registered with it a valued aperture corresponding to the value of the first named slide. The column thus served by these two valued apertures corresponds` in number to the sum of lthe binary value of the two slides shifted to Out position.

Referring now more particularly to Figs. 1 and 2 it will ber noted that each slide 20 has associated'with it a means 50 by which such slide can be shifted from ineffective (Im-position to effective (Out) position. This means 50` for all punposes and intent may be a straight forward push against a particular binary slide 20 or as illustrated in Fig. l, ak leverage 51.

It will be appreciated that the several lbinary slides 20 t snugly adjacent each other within the guiideway 13. If desired each slide 20 may have a return spring 52 connected thereto tending to return the slide to normal, ineffective or In position when aided by manual or mechanical force, as for instance by way of the leverage 51.

Each leverage 51 is identical so that a description of one will suffice. The leverage 51 comprises a lever arm fulcrumed as at 53 somewhere between its ends. One end 54 is a tab or push button while the opposite end 55 is a yoke adapted for operative connection to its associated slide 20. In this connection each slide 20 has a block or offset portion 56 adapted to fit within the yoke kend 55 of its associated lever arm 51. Consequently,

upon manipulation of the lever 4arm 51 (counter-clockwise Fig. 1)` the slide 20- associated therewith is shifted from ineffective to effective or Out position thus registering each valued aperture 22 on such slide with its related column C.

It should here be noted that once a slide is shifted to Out position its first binary valued aperture would immediately open up the column C associated therewith. Consequently, in order to serve only a column requiring several binary values, for example 2, 4 and 8 to serve column 14, it would be necessary to shift all of such binary slides (2, 4 and 8) simultaneously. While this simultaneous operation of the slides is contemplated, the present disclosure also includes the gate -slide No. 0, previously explained, which has the function of cutting off flow of fluid through any of the columns C until the selected binary slides have been shifted from In to Out position.

With the foregoing in mind it will now be assumed that uid under pressure is being supplied to the manifold chamber 12. In order to serve tube 18 associated with the column C valued nine, binary slides No. l and No. 8 are shifted to Out position as illustrated in Fig. 4. In this connection it will be noted that column No. 9 is already open at binary slides No. 2, 4, 16, etc. for the reason that the passage apertures 23 on such slides are already or normally registered with that particular column (9). Once these slides No. l and No. 8 are properly shifted to Out position all of their passage apertures are m-isaligned with respect to the columns with which they |were previously associated thus assuring that none of such columns will be opened. Simultaneously therewith column 9 is now conditioned for sewing fluid. In the present disclosure when the gate or master slide No. is shifted to Out position, fluid under pressure will discharge from the manifold 12 via column No. 9 into the tube 18 communicated therewith.

For the purposes of pointing out the magnitude of the present invention, Fig. has been elaborated upon along its left hand margin. It will there be noted that the addition of each binary slide doubles the number of columns 6 C whichcan be served. For example, it will be appreciated that lwhen 20 slides are used such 20th slide would be identified as binary slide No. 524,288 which would serve up to column No. 1,048,375, the next (21st) binary slide numbered 1,048,376 servingrup to` 2,096,751 and so on.

K In addition to the foregoing it will now be appreciated that the same results can be obtained with the structure illustratedy in Fig. 7 in which shiftable bars 20 are substituted for laminar slides 20. In this arrangement fluid is supplied from the manifold 12 as before into independent columnar ports. These ports are normally blockedby the shiftable bars 20 guided in bores '13" extending parallel to the manifold to traverse the columnar ports. These shiftablebars 20" have annular grooves 21" in lieu of apertures which grooves are either valued ones 22" or passage' grooves 23" for the same reasons as explained in connection with the preferred embodiment of this invention.

The same results are obtained in an arrangement such as that depicted in Fig. 6 showing a plurality of coaxial tubes or sleeves 20. In this arrangement the innermost tube` 14' constitutes the manifold 12 which has a plurality of radially arrayed apertures or ports as does the outermost tube 16. The intermediate coaxial tubes 20 which are comparable to the slides 20 are provided with ports or apertures adapted to register or become offset relative tothe radially arrayed apertures in the manifold wall 14' and the plate or outermost wall 1=6 of this arrangement. Each intermediate coaxial tube 20 is provided with valued apertures 22 and passage apertures 23 in a pattern corresponding to that previously mentioned in the preferred embodiment so that when one or more of the coaxial tubes 20' are rotated or turned relativeto the others and the manifold, a columnar port is` established at a preselected one of the radially arrayed apertures in the manifold. In this arrangement the intermediate coaxial members are also adapted for sliding movement lengthwise the manifold. To this end then the radially arrayed apertures in the manifold wall 14 can be grouped in accordance with digital values so that one group thereof -will serve ports from 0 to 9 and by shifting lengthwise the manifold 12' another group of ports valued from l0 to 19 can be served if desired.

In any event it will be appreciated that the present invention embraces a series of collective, independently movable ported members adapted to assume one of two positions for serving a preselected identifiable columnar port to effect operation or transmit intelligence to some other instrumentality.

While the device herein has been described in specific detail it will be appreciated that it is susceptible to modification, alteration and/ or variation without departing from the spirit of the invention it contains. I therefore desire to avail myself of all modifications, alterations, and/or variations as fairly come within the purview of the appended claims.
