Hammer H Hob/APB 4 men/9% 1 l SWIMMING POOL SKIMMER WITII VACUUM AND SWEEPING CONTROLS BACKGROUND or THE INVENTION Swimming pool skimmers of a type-embodying an inlet throat having a floating weir and leadinginto an upper chamber from whichwater is drawn downwardly through a leaf basketsupported by its rim in a lower prevent air from being drawn into the pump line which applies suction to the bottom of the chamber; and with an equalizer line'leading from the pool into the bottom of the lower chamber and controlled by a restricting check valve where it discharges into the chamber, for
regulating and limiting the negative pressure developed in the lower chamber.
SUMMARY'OF THE INVENTION The present invention provides a skimmer of the type outlined above, except that itdoes not have a float valve in the lower chamber of the skimmer, and in addition, it provides a lateral valve chamber to which the main drain line (leading from the bottom of the pool) is connected; a plug valve which is rotatably operably to selectively cut off the main drain connection (e.g., for vacuuming operation); and a diaphragm valve which covers the lower chamber and is rotatably operable to regulate the volume of flow from the upper to the lower chamber, and which has a closed position in which it provides for communication between a vacuum cleaner hose and the lower chamber beneath it and cuts off communication between the skimming inlet and the lower chamber, so that the full suction of the pump inlet line can be applied to the vacuum hose.
OBJECTS OF THE INVENTION The general object of this invention is to provide a skimmer having self-contained valve means for cycling a swimming pool circulatory system from normal filtering operation to sweeping operation or to vacuuming operation and back to normal filtering operation.
This and other objects will become apparent in the following specification and appended drawings, wherein:
FIG. 1 is a vertical transverse sectional view of a skimmer embodying the invention;
FIG. 2 is a horizontal sectional view thereof, taken on line 2-2 of FIG. 1;
FIG. 3 is a plan view of the equalizer valve;
FIG. 4 is a sectional view thereof; and
FIG. 5 is a sectional perspective view of the skimmer.
Referring now to the drawing in detail, I have shown therein, as an example of one form in which the invention may be embodied, a skimmer having an inletduct A leading into an upper chamberB; a lower chamber C containing a leaf basket L, a connection to a main drain line D leading to the bottom of the pool; a lateral chamber F communicating with the upper chamber B and with the drain connection; another connection (at 2 the bottom of lower chamber C) to a line P leading to the poolcirculation systempump; a diaphragm valve V covering the top. of lower chamber C, to control the" flow from the upper to the lower chamber; a plug valve 7 VI disposed in the lateral chamber F, to control flow from the main drain D into lower chamber C; and an equalizer valve V2. (FIGS. 3, and 4) controlling flow from equalizer line E into the lower chamber C.
Chambers B, C and F- are defined within a housing comprising upper and lower sections 10 and 11 secured together at"12. Inlet duct A is integral with upper section 10. A removable lid 13 normally closes the top of section 10 and cooperates therewith to define upper chamber B. Lid 13 is of transparent material, providing a see-through function for inspection of the internal condition of chamber B. Lateral extensions 14 and 15 on housing sections 10 and, 11 respectively cooperate tion 1 l at the upper end of inlet member 18.
The skimmer is installed in the deck 20 of a pool having a'sidewall 21 and an inlet port 22 with which the duct A communicates. A conventional floating weir 23 controls the inflowthrough duct A. Equalizer line E communicates with the pool through wall 21. The circulation pump (not shown) has it inlet connected to line P to apply suction to lower chamber C. Chamber F communicates with upper chamber B through a top opening in housingextension 14, and with lower chamber C through a lateral opening in lower housing section 1 1.
A separator plate 25 (FIG. 2) has a circular flange26 fitted into an enlarged rim portion 27 of lower housing section 11 and resting on an annular offset shoulder 28 joining such rim portion to the main body of section 1 l.
Valve V is of inverted pan form, comprising a flat disc 35 and a cylindrical rim 36. Disc 35 is seated on the top wall 32 and its rim 36 is rotatably fitted around lateral wall 31. The valve is held down against the valve seat disc 35 by a rivet or bolt 37 located at its center and allowing the valve to be rotated relative to the valve seat. In the valve rim 36 are a plurality of circumferential slot openings 38 corresponding to valve seat slots 33 and adapted to be registered therewith, either fully orpartially by selective rotation of the valve, thereby to define ports for skimming flow from upper chamber B into lower chamber C as indicated by arrows. The rim webs separating the :slots in the valve and valve seat members are somewhat longer in circumferential extent than the slots themselves, whereby the valve V may be rotated to a position in which the slots of one member are completely closed by the rim webs of the other member and vice versa, thus cutting off flow from upper chamber B to a lower chamber C. Valve V may be provided with diametrially opposed wings 39 for engagement by an operators fingers to rotate the valve.
For vacuuming, the valve disc 35 is provided with an opening 41 which, in a closed position of valve V will register with a vacuum coupling fitting in the form of an integral depending open sleeve 42 on valve seat 32, whereby the end nipple of a vacuum hose (not shown) may be inserted through the opening 4Iand wedged into the sleeve 42 for a vacuuming operation. The preferable'type of hose for such use is one having an end nipple of soft, resilient rubber or elastomer material.
Plug valve V1 comprises a cup-shaped valve body 45 loosely projecting through an opening 46 in separator plate extension 29 and having a pair of diametrically opposite lugs 47 integral with its lateral wall and projecting outwardly for resting on a pair of diametrically opposed lands 48 integral with and projecting upwardly from extension 29 along the edge of opening 46. Lands 48 have ramp ends 49 communicating with arcuate slots 50 in extension 29. At their opposite ends, lands 48 have upwardly projecting stop lugs 51. In a normal position of valve V1, the lugs 47 rest on lands 48 to support the valve cup 45 in an elevated position in which its bottom is spaced from the upper end of main drain boss 16 to provide for free flow from drain line D into lower chamber C for a bottom sweeping operation.
For the sweeping operation, the valve V is rotated to a closed position in which the ports through slots 38, 33 are completely closed. In this position, the opening 41 will be in closed relation to the opening in sleeve 42 to maintain a satisfactory vacuum in chamber C sufficiently to draw water from the bottom of the pool.
On the underside of separator plate extension 29 are diametrically opposed downwardly projecting lands 55 having ramp ends and stops 49 and 51 corresponding to those of lands 48. By rotating valve cup 45 until lugs 47 drop through slots 50, and then continuing the rotation until lugs 47 are engaged beneath lower lands 55, the cup 45 will be locked in a closed position in which its bottom is rested against the upper end of main drain boss 16, thus effectively closing off the main drain connection for a vacuuming operation in which the suction in lower chamber C is concentrated and applied to the vacuum hose coupled to sleeve 42.
For normal filtering operation, the valve V is adjusted to an open position in which an adequate flow through skimming inlet duct A may pass through ports 33, 38 into lower chamber C and thence be drawn through suction line P into the circulation pump. In travelling through chamber C the flow passes through leaf basket L which retains the leaves and other floating debris.
' The equalizer valve V2 comprises a valve poppet 60 .mounted by a compression spring 61 to a bracket arm 62, normally seated over the mouth of equalizer fitting l8 and adapted to be unseated when insufficient water enters duct A to maintain a primed condition, such as when the water level in the pool is below inlet duct A. For vacuuming and sweeping operations, the valve can be locked in'closed position by means of a lockout arm 63 mounted for swinging movement on a post (e.g., screw) 64 which also mounts the bracket arm 62 on top of arm 63. Lockout is effected by swinging the arm 63 1 to a position beneath arm 62, in which arm 63 will engage above the hub boss of poppet 60 to hold it down against the equalizer inlet 18.
