These brackets are removably secui‘ëdto 'the body f?îeinber I by means of bolts 2,408,562 3 4 I3 affording the mounting thereof on a suitable support (not shown). This arrangement of the port 8 and the brackets 3 makes possiblea ready the end of the stem 23 and opens the valve I5 maintaining it open while the crank arm 33 en gages the stem 22 and opens the valve I4. _Both and eñcacious coupling or stacking of two or more valve units as shown in Fig. 4 and as will be hereinafter more fully described. Valves I4 and I5 have stems of uniform diame ter mounted in the bores 2 and 3 for controlling the flow of iiuid from said bores into the outlet ports 4 and 5. These valves are urged by springs I3 to seat against the inner ends of tubular valve seat member Il snugly fitted in the bores 2 and 3 and having marginal flanges I8 abutting annu lar shoulders I9 in said bores. Ports 2B are pro vided in the seat members I'I to afford commu nication of the diametrically enlarged inner por tions of the bores of said seat members with the outlet ports 4 and 5 respectively. Stems 22 and 23 for the valve members I4 and valves are now open and ñuid will flow through Cil the bores 2 and 3 andout through the two outlet ports 4 and 5 thereby delivering a greater amount of fluid for an emergency servicing of parts or part to be de-iced. The emergency operation requires that the operator hold the handle in its uppermost or emergency iiow position as shown in dotted lines in Fig. 2 and upon release of the handle the spring for the valve I4 will push the handle back to normal flow position thereby mov ing the cam 32 olf the stem 23 and disposing the cam 3| in position to hold the valve I5 open while the valve I4 is closed. A feature important in this valve unit is that the intercommunicating port 8 serves the pur pose of connecting the bores 2 and 3 with one I5 respectively, extend through the seat members 20 another and facilitates the coupling or stacking I l and openings 24 in a plate 25 secured by 'screws ‘of two or more units together in an efficient man >25 to one side of the body member I. This plate ner as shown in Fig. 4. To do this the angular closes the adjacent ends of the bores 2 and 3. Ex brackets 9 on the valve units are removed and pansible sealing rings 2l surround the valve stems the units then placedfside by side with their ports between the outer end-s of the seat members Il 8 in registration. Two of the plates 9 are then put and the plate 25 there being crowding rings 28v back on the outer sides of the >units to cover the between the seat members and said sealing rings. outer ends of the connected ports 8, and longer Each of the valves I4 and l5 as here shown bolts are inserted through the body members, the -comprises a flanged head 23 formed integrally bolt holes thereof being also aligned, and the 'with and being of larger diameter than its stem, two units are thus coupled for independent op and a cup-like valve member 33 of yieldable ma eration except that the supply of pressure fluid terial such as rubber or synthetic rubber which 'encompasses said head so as to present an annu lar supplementary seal» against the associated seat member Il' while surrounding the head 25 which i.. also engages the seat member. .The head 29 iits snugly in the socket afforded by the member 33 land securely holds said member on the head. A boss 35a on the member 3!) acts as keeper for the vassociated spring I6. In accordance with this invention the outer 'ends of the valve stems 22 and 23 project beyond -the plate 25 so that they may be engaged by valve operating means including cam surfaces 3I and passes from one to the other of the units through the connecting ports 8 and but one supply line connected to one of the units need be used. With 'the plurality of valve units thus stacked, different portions of the aircraft maybe serviced at will and the units are compactly mounted and take up but little room, it being unnecessary to run more than two fluid lines from each unit except the one to which the fluid supply line is connected. Fur thermore, a distinct advantage results from the u-se of the particular type of intercommunicat ing ports 8 in a series of valve bodies stacked as v32 and a crank arm 33. These cam surfaces andi 45 aforesaid, because the aligned ports 8 provide a„ straight unobstructed passage through the inter "the crank arm are provided on the inner end of a handle 34 pivoted on a pin 35 carried by flanges 38 on the plate '25. The handle 34 is held in proper position on the pin 35 by means of a spacer `sleeve 37 and a spring 38 as shown in Figs. 1 and> 50 3, said spring holding the parts against rattling. .In its neutral or off position the handle 34 ex .tends downwardly andA outwardly from the pivot end 35 as_shown in full lines in Fig. 2, and the >cam surface 3l which is planar, is disposed angle to the outer end of the stem 23 of the I5 and close thereto while the crank arm >‘spaced well outwardly from the valve stem at an valve 33 is 22 of -the valve I4, both said valves being then closed. mediate units of the series. This advantage re -sults from the fact that only opposite side por tions of said port 8 communicate with the pas sages to which they deliver the incoming fluid. Fig. 5 shows a diagram of a typical anti-icing system as used in aircraft as when operating to "supply a normal ñow of fluid, and which includes a reservoir A, and a pump B for delivering fluid vthrough a supply line C to a control valve unit D embodying my invention. Line E leads from the normal flow outlet port 5 of the unit D and line vF leads from the emergency outlet port 4 of said unit and said lines have a common outlet G where In order to set the valve unit for a normal iiow 60 it is desired to apply the fluid.

In a ñow control valve unit, a body member having a pair. of valve-receiving bores extending ing handle is designated45 and is pivoted on a pin 46 on the valve body in the same manner as shown in Figs. 1,2 and v3, and has a planar >cam surface 41, and a crank arm 48 for engaging f the stems of the two valves. When the handle 45 is in neutral or off position it extends sub stantially at right angles to the major axis of the body member of the unit. The planar cam transversely therethrough in spaced relation to one another, means for intaking fluid under pres sure -into vone of said bores, an intercommunicat ing port extending transversely through said> body member from one outer surface thereof to an opposite outer `surface thereof and having between its ends an intermediate portion which surface 41 is then disposed close to the stern 23 and substantially ¿at right angles to the axis of 20 bridges the space between said two valve-receiv ing bores whereby pressure fluid will flow from the stem while the crank arm is spaced from surface 41 engages the stem 23 and unseats the said one bore to the other bore, outlet ports ex»r tending longitudinally in said body member from said bores through opposite outer surfaces'of said body member, valves in said bores for controlling the flow of fluid therefrom into said outlet ports, valve l5 and when the corner 49 of this cam sur valve operating means mounted on f said body face is centered on the stem the operating means will remain in normal flow position maintaining member, and closure means mounted on said body for closing the ends of said intercommuni eating ports subject to removal to permit of cou stem 22. The spring of the pin 46 operates tok hold the handle in this neutral position. Upon depressing ther handle 45 into the lower ' most dotted position as shown in Fig. 6 the' cam` the valve l5 Vopen while the valve I4 is closed. „v To effect an emergency or full iiowA operation pling together the body members of at least two of the valve units with the intercommunicating ports thereof vin‘registration with one another. of the unit, both valves are opened by raising the handle 45 into the uppermost dotted position shown in Fig. 6 whereupon the corner 56 of cam~ surface 41 will center on the stem 23 for the valve l5 and maintain said valve open while the crankl arm 48 engages the stem 22 and moves it to un 3.

I claim: ` ‘ 1. In a ñuid control valve unit, a body member Y having a pair of valve-receiving bores therein in a parallel adjacent relation to each other, means bodies having through it a horizontal intercom- , municating port consisting of a bore the width of which spans the space between the aforesaid ad jacent enlarged end portions of said valve-con taining bores and thereby affords communication between the latter bores, said intercommunicat ing ports alining with each other to form a . passage within the assembled valve units extend ing in the direction of their alinement, closure means for the opposite ends of said valve-receiv ing bores, said valve stems projecting slidably through said closure means at one side of each . valve body, means operatively related to'the pro jecting portions of said valve stems to operate for intaking fluid under pressure into one of said the valves, inlet means for atleast one of said bores, an intercommunicating port extending valve bodies communicating with at least one of through said body member and so positioned that its width bridges the space between said bores at its said diametrically enlarged bore portions, and ` a point intermediate of its ends to afford the pas- 1 sage of pressure fluid from one to the other of said communicating ports at each end of the assem- n bores, closure means to overlie a side of said body member for closing either of the ends of said in- l closure means forthe outer ends of said inter Ab_led valve units.
