In this embodiment the necessary additional buoyancy force to acheive objects of the present invention, is attributed to the fact that the air, being trapped, becomes an air cushion having the qualities of a spring, and will, accordingly, due to compression of this air cushion, offer resistance to dropping of the float by action of the pump. However, as the float proper submerges, the air chambers 39 then begin to submerge and add to the prevailing buoyancy force exerted upon the float, thereby reducing the ability of the pump to drop the float to the position which it would normally occupy in a conventional or prior art weir assembly, with the result that a thinner sheet of water will flow over the weir and with greater velocity, which is what the present invention seeks and what is desired in a weir assembly. Application filed by Jacuzzi Brothers Inc. When the dimensions of the wall opening are so related to the length of the flanges bordering the mouth of the tunnel, the skimmer assembly can be installed from the rear side of the pool wall by first inserting one of the flanges 69 of less length than the corresponding dimension of the wall opening (See FIG. Extend Machine Life Timely replacement of accessories is conducive to the extension of the service life of the machine, this skimmer gate weir baffle is suitable forPENTAIR. The combined effect of the pump and the weight of the layer of water flowing over the weir results in a relatively thick layer of water flowing over the weir, thereby cutting down velocity of flow and impairing effecienty of skimming. The entire skimmer assembly is then retracted to bring three of the flanges into contact with the metal panel 65 of the wall, following which, the skimmer assembly may be mounted to the metal panel by bolts through the metal panel and contacting flanges. 6 is a front view partly broken away of the skimmer assembly installed in a pool wall; FIGS. It will fill up to the level of the water in the pool, with the pool pump in a quiescent state, and the weir assembly will float with its upper portion slightly above the level of the surrounding water. Then by starting the pump, the vacuum sweeper can be moved along the bottom of the pool to vacuum the same, and any debris picked up by the vacuum sweeper, will be strained through the strainer basket which will remove the larger items, it being important to note in this connection, that the strainer basket need not be removed when vacuuming, as is necessary in prior skimmer assemblies of this type. With this simplified design of the second embodiment, the float characteristic is primarily attributed to the fact that when installed in the weir assembly housing, air will be trapped within the inverted channel to create an air chamber, thus providing the necessary buoyancy. While the mode of operation of the embodiment described above is not too clear, it is believed that, by reason of the clearance existing between the skirt and the proximate wall of the weir assembly housing, the buoyancy force against the bottom 33 of the float of the weir assembly will always be that exerted by the water at the level of the water in the tunnel, and that this buoyancy force will be opposed by the suction force of the pump when the pump is functioning, plus the weight of the layer of water flowing over the weir. Such additional buoyancy may take the form of additional sections of foam plastic affixed to the upper surface of the float housing, or may take the form of air chambers molded into the float housing as illustrated. 204g/7.2oz Package List: 2 xSkimmer Assembly Note: Manual measurement, please allow 0.40.7in error.

When it becomes necessary to drain the pool itself, then all that is necesary to do is to plug up the neck opening of the vacuum by means of an appropriate cap and then exposing the main drain line 11 from the pool, to the pump suction opening 7 by swinging the valve to a midpoint between the two. The surface water of a pool is cause to enter the skimmer and flow over a weir carrying such debris with it, following which, the larger bits of debris are removed by a basket through which the water flows on its way to the pool pump. Toward this end, the tunnel 9, at its entrance end, is of rectangular configuration, bordered along both dimensions by mounting flanges 67, 69. Assignors: JACUZZI BROS., INC., JACUZZI WHIRLPOOL BATH, INC. Upon starting up of the pump, water will be withdrawn from the weir assembly housing to the point that the weir assembly will now be somewhat submerged below the level of the water in the tunnel, thereby causing a flow of water over the weir into the weir assembly housing and to the pump, via the strainer basket which will remove any debris such as leaves and the like. Aggravating this situation, is the fact that the thickness of such layer of water flowing over the weir will fluctuate in response to wave motion imparted to the incoming water by prevailing conditions in the pool, and such fluctuations will cause the float to respond and oscillate vertically in what may be termed bouncing, which, in turn, will further aggrevate the situation. 1 is a view in section through a skimmer assembly embodying the features of the present invention, illustrated installed in a pool of the liner type; FIG. Unable to add item to List. The method of installing a skimmer assembly in a swimming pool wall comprising forming in said wall, a rectangular skimmer opening of predetermined length and width dimensions, fabricating a skimmer assembly having a tunnel terminating in a rectangular opening at its intake end, bordered by a flange, said tunnel opening plus its flanges having one of its dimensions exceeding the corresponding dimension of said wall opening and its other dimension slightly less than the corresponding dimension of said wall opening, inserting said intake end of said tunnel through said wall opening from the rear side thereof by first inserting one of the sides of less dimension than said opening, through said opening, followed by the opposite side, then backing up the skimmer assembly to bring the flanges of said opposite sides plus one flange of a connecting side, into engagement with the front side of said wall, leaving a slim opening along the remaining flange, affixing said skimmer assembly via its wall engaging flanges, to said wall, closing said slim opening with a closure, and then covering said wall and closure with a liner. 8), which results in the entire flanged end of the tunnel appearing on the pool side of the wall (See FIG. By installing the skimmer assembly in this manner, the entire skimmer assembly may be preassembled and then installed in a very simple and direct manner to the pool wall.

Thus, wave motion stimulates such chain of events, each stage of which produces an additional adverse effect on the skimming ability of the skimmer assembly. The inertia thus imparted to the float will cause it to bounce or oscillate, whereby the efficiency of the float as a weir becomes impaired because, for one thing, the thickness of the layer of water flowing over the float will fluctuate accordingly. Conventional type skimmers utilizing hinged weirs, oscillate freely with wave motion and consequently are not conducive toward causing a thin layer of water to flow over the weir, still less a thin layer which is more or less stable.

In the second embodiment of the invention as depicted in FIGS. This leaves a slim opening along the remaining flange, which opening is then closed by a backing plate 77 applied against the rear of this flange and the proximate edge of the metal panel opening, to which the backing plate is affixed by mounting bolts. 1996-2022, Amazon.com, Inc. or its affiliates, Learn more how customers reviews work on Amazon. Circular type weirs respond to a differential force attributable for the most part to bouyancy of the water within the tunnel as opposed by suction of the pool pump when operating, and any changes in the level of water entering the tunnel attributable, for example, to wave motion, will cause changes in position of the float within the float housing. In the preferred embodiment, the longer flanges exceed in length, the longer dimension of the opening. Referring to the drawings for details of my invention in its preferred form, the embodiment illustrated is designed primarily for installation in a pool of the liner type. Available skimmer assemblies present additional problems which the present invention seeks to remedy. Installed just above the strainer basket is a floating weir assembly 27. 4; FIG.
