Abstract
ABSTRACT
A pail mounted pump system having dual reciprocal pumps and pail cover in an integral design. The pump and pail cover are constructed in a single unit with a built-in intake siphon tubes. This arrangement provides dual pumps pumping the same fluid which keeps the system pumping should one of the pumps fail. The pail cover is formed with a recess and mounting holes for mounting a pump. A skirt on the cover has a flange on its inner surface forming an annulus which seats securely on the pail rim. A recirculation/agitation system is provided by a hose connected through a valve to the pump outlet recirculating fluid back to the pail through an aperture in the cover.

FIELD OF THE I~VENTION
.
4This invention relates to pumps and more particularly relates to a low profile integrally formed pump and pail cover.
7 l ¦ Often, for portability, pumps are mounted directly on 8 ¦ ~aint containers or pails. It simplifies and eliminates the ¦ need for trans~erring the paint or other liquid from the pail to another container. Such procedures are generally messy and time 12~ consuming and are unnecessary where there are relatively small ~ ~obs involved.
13 To solve these problems purnps have been mounted directly I on the pail for delivering the fluid from the pail to the joh 15¦ site. The usual procedure is simply to have a lid, very similar 17~ to the normal flat lid pressed on the pail, with the pump simply l bolted to the lid with its intake tube immersed in the fluid.
I81 problem with such an arlangement is that the pump is heavy and 20~ has a high center of gravity making the combination of pump and ¦ pail unwieldly and as well as unstable. ~ further problem is 22 that pump failure completely shuts down the system. Often in 23 trying to move the pump and pail the system can easily be tipped 24 over causing spillage as well as damage to the pump. It would 251 be advantageous if the pump and pail cover arrangement could be made to be compact, stable minimize shut-downs and have as low a profile as possible ¦ Thus the present invention in one aspect seeks ¦; to provide an integral pump and pail cover having a very low proiile.
31 Further the present invention seeks to p:rovide 32 a pump and pail cover arrangement which is compact in design and easy to use.

7 More particularly -the present invention seeks 8 to provide a pail mounted pump having a pail cover which 9 provides a low profile to prevent tipping of the pail~
1~ The pail cover is constructed with a skirt which will 11 fit around the periphery of the pail. Beneath the skirt 12 is a flange having an annulus to :Eit around the rim of 13 the pail to seal and minimize spilling of fluids in the 14 pail and stabilize the purnp and pail cover. Preferably threaded apertures in the skirt receive thumb screws to 16 firmly secure the pail cover and pump to the pail. The 17 thumb screws allow the pump and pail cover to be easily 18 and conveniently removed and transported to another 19 pail. The pail cover is constructed with a recess for receiving the pump housing to maintain the pump and pail Z1 cover to provide very low profile. In a preferred 23 aspect, the pail cover receives a return tube diverted 24 from a manifold on the pumping system which allows fluid to be recirculated back to the pall from the pump. A
26 return tube extension is connected to the aperture to 27 return recirculated fluid to the bottom of the pail 28 thereby preventing air from entering the system and 29 agitating fluid at the bottom of the pail to keep the fluid well mixed.

DETAILED DESCRIPTION OF THE INVENTION
_ 16 This invention is for use with pumps such as 17 that disclosed and described in United States Patent No.
18 4,516,725 and the patents cited therein. The pump is 19 constructed to be very efficient and pump effectively, a variety of high viscosity and abrasive fluids.
21 Referring to Figure 1, pump 10 is comprised of a pair of 22 alternating reciprocal pumps 12 and 14, driven by a 23 double acting reciprocal air motor 16. Air motor 16 is 24 driven by an adjustable valve 18 from a source ~not shown) which is regulated by pressure gage 19. Outlets 26 20 and 22 of alternating reciprocal pumps connect to 27 manifold 24, 25 for delivery to quick connect/
28 disconnect hose fitting 26. The quick connect fitting 29 is normally closed when no hose is connected. This 2a IL~0057:~L
1 fitting allows the pumping system to be easily and quickly 2 connected to a delivery system (not shown) such as a spray head 3 or gun.
4 The pumps 12, 14 draw fluid from pail or container 28 through intake or pickup tubes 30 and 32 which alternately draw 6 the fluid and deliver it through manifold 24, 25 to fitting 26.
7 The dual alternately reciprocal pumps have an added advantage 8 over prior pail mounted pumps in that one pump will continue to 9 deliver fluid should the other stop pumping. This provides the distinct advantage of two pumps for the same fluid in which one l1 ¦ would keep pumping should the other fa~l.
12 ¦ Pail cover 34 is formed to securely mount on the pail 28 13 and is designed to be integral with pump 10. The cover 34 has a l4 ¦ skirt 36, mounting holes 38 for securing the pump, and a well or 15¦ recess 40 for receiving the air motor housing at 42 (~ig.2).
16¦ The purnp 10 is secured to pail cover 34 by bolting through bolt 171 holes 44 into hosses 46 and 48 mounting intake tubes 30 and 32 181 on the pumping system.
l9¦ Skirt 36 has a circumferential flange 50 on its interior surface forming an annulus 52 which seats on the rim of pall 28 21l with thumb screws or wing nuts 5~ adjustably mount~d in threaded 22~ holes. The integral pump and pail cover assembly is mounted by 23 seating the rim of pail 28 in annulus 52 and tightening thumb 241 screws 54 tightly against the outside surface of the pail.
25l A recirculation and agitation mode is provided by 261 recirculating hose 58 secured to hole 56 in the cover by lock 27 i1 nut 59. Valve 60 opens and closes flow from coupling 26 and 28 ! rnanifold 24, 25 to hose 58 diverting flow back to the pail 58 29~ diverting flow back to the pail for continuous recirculation.
30l During .spraying operations when the delivery system is 31¦ ternporarily off the fluid is kept agitated ~nd recirculated by 32 op~ning valve G0 allowing continuous flow of fluid throu-~h the ~ s~
1 pump back to the pail to keep the paint or other fluid fully 2 mixed. As an alternative, a return pipe 62 (Fig. 2) could be 3 pxovided to be sure fluid return is beneath the surface of the 4 fluid in the pail. This prevents air frorn entering the system.
S It also assures that material at the bottom of the pail will be 6 stirred to prevent it from thickening. Lid 64 is secured by a 7¦ thumb screw 66 covers a port in pail cover 34 permitting the 81 user to view the fluid contents in pail 28 or to act as a vent.
9¦ Thus there has been described a unique pump system and 10¦ pail cover assembly for use on paint pails or the like which ¦ provides an inteqral compact assembly which is both stable and 2¦ low in ~rofile when mounted on a pail. The system provides the 131 added features of a recirculating system to keep the fluid in 14~ the pail constantly recirculating or agitating when the system 151 i5 not in use. The pump system when mounted on the pail is very 16¦ portable, easy to carry and ideal for hard to reach jobs.
17 This invention is not to be limited by the embodiment 18 shown in the drawings and descrihed in the description which is 19 given by w~y of example and not of limitation but only in accordance with the scope of the appended claims.
