4 Claims. (Cl

The invention relatestovalve, actuation.' and isdesigned primarilyfor the operation of. the now-reversing valve of a dye vat or the like, to alternately direct the dye liquor from theoutside in, and from the inside'out, and the principal object is to provide a rather simpleyet` 'reliable mechanism for automatically attaining this en d. In'this connection," aV further aim is to make novely provision'for showing at a glance inwhich direction the dyeliquor isrflowing e u d Y The actuatingr mechanism for the reversing valve isl operated-by-,a pressure uid (prefer ably compressed air) acting against a piston in al cylinder, and. another object is to providefor easily mountingsaid actuating. mechanismY and.

The above mentionedpressure lluidmust, be

directed rstto one end ofl thepressure cylinder and then to the, other, and astill further., aim is ltof make novel. provisionvior accomplishing thisend. f, With the foregoing in view,A the ,invention resides in the novel subject matter hereinafter described and claimed, description being accom` plished by reference to theaccompanying draw-v ings.

.Figure- 1 is afront Vention.

Figs. 2, 3 and 4 are sectional; views as; indicated by theelines 2-2, 3c--3 and 4-4 of Fig..1. A preferred construction has` been illustrated and. will; be. rather specifically described, with the understanding, however, that .within the scopeof the invention `as claimed, variations may be made. Moreover, whileV the invention is intended primarily for use in connection with dyeing equipmena'it` isto` be..understood that it is not* restricted to this rparticular iie'ld of iuse. Liquid-conducting means; is. shown including two laterally spaced 4parallel reaches :5 and E, rigidly connected by a lbra'nch 1. The reach 5 includes a valve body 8 in which there is an oscillatory valve member 9, this reference character 9 being applied to the operating or shaft portion of the Valve member as it is the only portion shown in the drawings. One end of the branch 1 is, in the present disclosure, formed by an elbow I secured by a anged coupling II to the upper end of the valve body 8, the bolts which secure the anges of this coupling together, being shown at I2 for further reference. The reach 6 and the branch 'I are preferably elevation showing.v the in.-

formed from a T coupled at I3 to the elbow I0.

Thus, the uid-conducting means formed by the 5137-78): demente s,l I1, is, io, ujizfena a., is,` ef. inherently rigid nature.

A rigid .bracket I4 is, secured .to thev reach 15. and projects forwardly therefrom said bracket d beingin the present disclosure. providedA with a forked inner end l5 Which- Straddles. the lower.

end of Vthe `elbow IIJ and is. secured to theflangedl coupling I I by a. number of its. bolts. l2.4 The. outer end of this bracket VL4 hasjari integrali head I6 projecting downwardly therefrom, the lower. side of said head being formed with a horizontal T-.slot II. Immediately above the-head I6, a 1ug,I8 projects'. upwardly frornfthev bracket Il, and, a reinforcingl web I9 may well' be. integral. with said lug and bracket, ask shown.

'clamping .bolt 24.. The outer or forwardjend of.' thelbracket 22. rigidly` supports `a pressure `cylinder 2.5 whichijs. secured thereto by cap screws or thellkel. Cylinder 25. contains` a piston 21, the piston rod 281v of which. is secured to thev rack 20v above. described.; the, rack. being thus operable. by means. of the piston.V u

Y l

It will be observed that the bracket I 4 is so anchored to the anged coupling II that there is Yno danger Whatever of said bracket swinging to trolling a plurality of die vats or other machines I since in order to do that it is only necessary to mally raised. Let it be assumed that when both plungers are in raised position, they open both ends of the cylinder to the atmosphere; and that when either plunger is depressedf-,it cuts off communication between ,one end ofthe cylinder and the atmosphere and simultaneously directs the pressure fluid into said end. Thus, the piston will be driven toward'the other end of the cylinder and this end will, at thesame time, exhaust to thevatmosphere.. A, v

'I provide two cams 38` for depressinghrst one andthen the other of the -plungers 31, said'cams beingsecured tov V'a 'cam shaft 39 mounted' in appropriate 'bearings' 40. These bearings are'securedupon abase'Al located Wherever desirable, and' jthe't wo valves 35" are also' secured'to said base. suitable ratchet mechanism 4 21is operativelyrf connected with the cam shaft 39 for turning it in al step-by-step manner, and said ratchet mechanism may`be .driven by means oi an electric motor, 'for' instance, mounted` on `the base"4l. "The motor may well drive a, crankor the like (notf'shown) and motion may be transuse larger valves and feed lines. AI claim:

1. A hand mechanism of the class described comprising fluid-conducting means including two laterally spaced unidirectional reaches and a branch rigidly connecting said reaches, one of @said reaches having an oscillatory valve member at right angles to said branch. one bracket se- "cured to said one of lsaid reaches, a second bracket v secured to the other of said reaches, said brackets mitted to 'the ratchet,mechanism 42 from said crankor .the `like by meansjof Ya klink 42.

'QWith respect tf j operation, Atheratchet mechanislni 4'2 slowly'turns the camshaft 39 andwhen one. of the"` cams'j38 depresses the subjacent plunger' 31 fthe pressureviluid is admitted into one endi'of'the `A`cylinder 2 5A to` force theY piston 2 1 in irection causes the rack 20 and ,seg-

'Thevalve menivber :and .associated parts remainin this' position until the other cam 38 ldepresses the plunger 31 with 'which it is cooperable, whereupon the positionsof. parts are reversed with the result that thelflow of dye' liquor is reversed. These operations continue automatically as long as the mechariism is in operation`.` l 1 'i From the foregoing, taken in connection with the' 'accompanying drawings, it will be seen that novel and advantageous provision has been made for carrying out the objects of the invention, and while'preferred'features havebeen illustrated and described, attentionfis again invited `to the possibility of,V making` ,variations` within' the scopeA ofthe inventionasclaimem"1'. i
