Referring more particularly to the drawings, number 1 generally designates a bag for liquid and 2 designates a supporting assembly comprised of an elongated bracket 3 and a pair of corresponding generally U-shaped flexible hooks 4. v V

The bag is substantially of a one-piece-conshuction andis preferably made by folding a length of'a fabric .to provide a fold at its upper edge. The fabric is impregnated with a suitable plastic material so as to render ;the bag waterproof and at the same time-afford a means whereby, the lapped portions of the material can be bonded or united by the application of heat and pressure to form. a bottom grooveS, parallel side grooves. 6,]and top grooves 7. The bag is provided with side wing portions and longitudinal edge portions of the wings are bonded together to provide grooves 8 which are disposed in parallel relation to the side grooves 6. -The outer upper and outer lower corners of the wings are preferably bonded together over a greater area as indicated at 9 and 10 so as to reinforce the wings. Theside grooves and the grooves in the wings are spaced apart so as .to provide a pair of parallel pockets 11 which are adapted to detachably receive leg portions of the hooks. above referred to.

The :bracket is preferably elongated and provided with offset end extremities which carry the hooks. The supvehicle such as the fire wall as stated above in any manner desired, but as herein shown an intermediate fiat portion 12 of the bracket is provided with a pair of holes 13 through which fastening means may be extended for securing the assembly in place.

, Each offset extremity of the bracket is provided with wardly extending shorter corrugation 15 which in combination serve'to provide receiving or attaching means through which a'rear leg 16 of a' hook extends to support the hook for pivotal movement with respect to the bracket. Each extre'mity of the bracket is preferably provided with a rearwar'dly extending depression which forms a recess 17 'lo'cated adjacent'the upper end of the front corrugation as clearly shown in Figure 3. As a result'of providing the depression a shoulder is formed on eachiofiset to provide a stop 18. Each hook also includes a front leg 19 which is of a greater length than the rear leg so that the upper end of the front leg will The front legs of of the bag as clearly illustrated and the upper end of each front leg is preferably provided with a loop 20 so as to prevent said 'ends frompoking or wearing holes through the upper folded edge portions .of the bag.

The hooks are connected vto the bracket by merely insertingithe rear short legs through the corrugations constimtin'g the receiving or attaching means and then bending their free ends to provide offsets 21 which are adapted to respectively normally nest in the recesses 17 and engage the base portions thereof as clearly illustrated to limit inward movement of the front legs of the hooks to substantially right angular positions with respect to the bracket so that the bag when supported on the hooks will be maintained in a stabilized position in spacedapart relation to the inner legs of the hooks including the offset end extremities of the bracket to prevent the bag from chafing or otherwise rubbing thereagainst. It

will be noted that theoflset ends 21 of the rear legs of the hooks normally point toward one another and rest upon the stops 18 to prevent downward movement of ,the hooks with respect to the'bracket. Pivoting the hooks 'as described facilitates insertion of their front legs into sary to push upwardly on the hooks so that the oflsets 21 on the upper ends of the rear legs of the hooks are moved out of the recesses and above the upper edge of the bracket whereupon the hooks are pivoted so that the front legs thereof engage the bracket as shown in Figure 8. If desired, the hooks may be pivoted so that the front legs will engage the rear side of the bracket to place the supporting assembly in a different collapsed condition.

It will be noted that when the bag is properly supported as illustrated in Figure 1 it is held in a stabilized balanced position due to the location of the hooks and their points of connection with the bracket. The hooks, as pointed out above, serve to resiliently support the bag and due to the operative relationship between the hooks and the pockets of the bag the hooks and pockets will serve to alleviate any excessive torsional strains produced by the weight of the liquid in the bag and at the same time afford means whereby the bag is suspended against excessive side play or wobble. that the lower extremity of the bag extends below the lower ends of the hooks and as a consequence the lower extremity is held in a more relaxed state or condition than that portion of the bag located between the front legs of the hooks. The purpose of this will be subsequently described.

7 The bag is preferably provided with a tubular neck 22 which is permanently secured and sealed within a tubular portion 23 of the bag as illustrated in Figures 1 and 2. A closure or cap 24 is detachably secured to the neck and this. is preferably accomplished by providing the upper end of the neck with a. lip 25 and the cap with a tapered flange 26 of a size whereby the cap may be pressed onto the neck so that the lip will engage the inner cover surface of the cap and the free edge of the flange will intimately circumferentially engage the exterior surface of the neck at a location spaced longitudinally from the lip to provide a fluid-type connection between the neck and lip.

The cap is preferably provided with an integral upper tubular extension 27 and a lower tubular extension 28. A conduit 29 is adapted to be fastened to the upper extension 27 for communicatively connecting the bag with components of a washer system. A flexible tube 30 is connected to the lower extension28 as clearly illustrated and the lower end of the tube supports a combined valve and filter assembly.

The valve and filter assembly, as clearly exemplified, includes a tubular fitting 31 which extends into the lower end of the flexible tube, a tubular element 32 secured about the fitting and a tubular member 33 which serves as a valve seat for a ball valve 34 which is movable between this seat and the lower end of, the fitting 31. A cup 35 is secured to the lower end of the tubular element 32 and a filter 36 in the form of a fine meshed screen is detachably retained in. the cup by a flanged ring 37 functionally held in the cup. When the washer system, not

It will-also be noted shown, is operated one way liquid will be drawn up through the filter and unseat the valve to allow the liquid to flow through notch 38 in the fitting 31 and up through the fitting and tube. The size of the cup 35 is such that the lower portion of the bag will be slightly expanded and this expansion is permitted due to the relaxed condition of the lower portion of the bag as indicated above.

Having thus described my invention, it is obvious that various modifications may be made in the same without departing from the spirit of the invention; and, therefore, I do not wish to be understood as limiting myself to the exact form, construction, arrangement, and combination of parts herein shown and described and defined in the claims.

I claim:

1. An assembly of the kind described comprising a bracket and a hook, said bracket being constructed of sheet material and having a substantially planar portion deformed to provide an open-ended groove, said bracket being further deformed to provide offsets spaced from the planar portion and disposed at the ends of the groove, one of said ofisets in combination with the planar portion defining a recess disposed substantially transverse to the length of the groove, said hook comprising an inner leg and an outer leg joined to the inner leg and disposed in a plane substantially parallel thereto, said inner leg being mounted in and held in said groove by said offsets and having a lateral projection disposed in the recess and bearing against the adjacent offset for limiting downward movement of the hook and normally locating the outer leg in a predetermined substantially parallel relation to the said planar portion of the bracket for supporting an article.

2. The assembly defined in claim 1, in which the hook may be adjusted lengthwise of the groove to release the lateral projection on the inner leg from the recess so,

that the hook may be pivoted to cause the outer leg to overlie the bracket and thereby eflect collapse of the assembly.

3. An assembly comprising an elongated bracket, a pair of spaced hooks, each of said hooks having an inner leg pivotally connected to the bracket and an outer upright leg, means on the inner legs cooperating with the bracket for limiting pivotal movement of the upright 1 legs toward one another, and a container having a pair of substantially parallel inverted side pockets within which the upright legs are disposed for supporting the container and so the container serves to hold the upright legs against pivotal movement away from one another.

4. The assembly defined in claim 3, in which the bracket is offset intermediate the hooks so that the bag is spaced from the ofiset to prevent contact therewith.
