Battle Creek, Mich., assignors to H & H Engineering Division, Barker Manufacturing Co., Battle Creek, Mich., a corporation of Michigan Filed Jan. 10, 1967, Ser. No. 608,393 U.S. Cl. 103--178 Int. Cl. F041 21/04; B67d 5 42 4 Claims ABSTRACT OF THE DISCLOSURE Background of the invention The invention lies in the teld of art pertaining to manually operated pumps utilizing a cylinder having a reciprocal piston and piston rod located therein. Spout means communicate with the discharge portion of the cylinder, and the mount for the pump, spout and operating handle are closely related, constituting the only visible portion of the pump when installed.

Countertop pumps of the type of the invention have usually been constructed of brass or zinc. The pump of the invention is primarily constructed of noncorrosive A.B.S. plastic material and high strength, wear resistant synthetic plastic material such as Delrin, and one of the features of the invention arises from the fact that the pump components will not corrode or seize even after long periods of nonuse. While prior art pumps of the countermounted type have included spouts which could be removed during shipping, the interconnection between the spout and the spout mounting portion of the invention is unique and provides an economical manner by which the spout may be quickly and firmly attached to the spout support, and is particularly advantageous as used in conjunction with the nonmetallic construction of the invention. In prior countermounted puimps, a single mode of installation was required, and it was not possible to vary the height or profile of the pump, as in accord with the invention. The invention provides a versatility of installation not previously available.

Summary of the invention The packaging and handling of a countermounted galley pump is complicated due to the requirement for a relatively long spout. '111e spout normally extends from the pump structure a suicient distance to discharge directly into a sink or similar receptacle present in the galley of a boat, house trailer, camper, or the like, With metallic pump structures, the spout is often threaded into the spout support. However, a threaded connection will not permit rotation of the spout about its own axis without affecting the connection. Basic components of the galley pump in accord with the invention are formed of a non-corrosive plastic material, and a lightweight, economical and high strength interconnection is desired to connect the spout to the spout support which will permit limited rotation about its own axis without affecting the eiliciency of the connection. Rotation of the spout from an inoperative position to an operative position locks the spout to the spout support by a key and slot arrangement and inadvertent removal of a spout from its support is prevented once the pump is installed.

As the galley pump of the invention is adaptable for use in a wide variety of installations, such as in boats, trailers and campers, the dimensions, clearances, and positioning of the pump upon its supporting counter or horizontal panel may vary considerably in various installations. In some installations, it is desirable that the exposed or visible portion of the pump have as low a silhouette or prole as possible with respect to its supporting countertop. In other installations, it may be desirable for the visible portions of the pump to be vertically spaced above the countertop a higher distance to permit the spout to be placed in an optimum relationship relative to the sink, or for other reasons. As the spout support is mounted as a swivel upon the pump-mounting body, such extra clearance of the spout above the counter has advantage.

It is, therefore, an object of the invention to provide a noncorrosive countermounted manual galley pump including a spout which maybe readily removed from the pump structure, or attached thereto, and wherein the pump may be mounted in at least two different installations whereby the vertical relationships of the pump to its supporting counter may be selectively determined.

Description ofthe preferred embodiment intersects the peripheral edge 14 and extends inwardly of 3 the periphery a distance which will be appreciated from FIGS. 1 and 5.

The body 10 is also provided with a circular opening 18 which intersects the upper surface 12 and the opening is reinforced by a circular, raised embossment 20. A piston rod opening 22 is defined through the mounting body intersecting the upper surface and spaced from the openin 18.

gi chamber-defining wall 24 extends downwardly from the undersurface 16 and is set inwardly from the peripheral edge 14. The wall 24 terminates at its lowest portion in a bottom edge 26 and its configuration will be appreciated from FIG. 2, wherein the wall outer edge appears in dotted lines. The wall 24 will define a chamber 28 within the mounting body, FIG. 1, which communicates with the opening 18 and the piston rod opening 22.

The chamber 28 is closed at its bottom by the chamber plate 30 which is of a dish-shaped configuration, including the horizontal portion 32 and upwardly extending peripheral ange 34. The configuration of the plate 30 is complementary to the wall 24 wherein the flange 34 may intimately engage the inner surface of the wall and be bonded thereto to provide a sealed connection. An annular, cylindrical stem 36 extends downwardly from the plate portion 32 and is in turn provided with a bore and outer surface concentrically related to the piston rod opening 22.

A pump cylinder 38 is mounted upon the cylindrical stem 36 and sealed thereto. The lower end of the cylinder 38 is provided with a molded fitting 40 which seals the end of the cylinder and includes a bore 42 extending through the reduced diameter portion 44 having annular serrations formed thereon whereby a rubber or plastic tube, or the like, may be inserted over the portion 44. The fitting 40 includes a conical seat 46, and a check valve ball 48 is mounted within the fitting to control the fiow of fiuid through the fitting limiting fiuid fiow through the fitting into the cylinder wherein the fitting 40 comprises the cylinder inlet.

A metallic piston rod 50, which may be formed of aluminum, extends through the opening 22 and is provided with an upper end upon which the handle 52 is afiixed. The lower end of the piston rod is provided with spaced annular grooves which receive

snap rings

54 and 56. The snap rings axially position a piston retainer 58 upon the piston rod which is formed with openings 60 through which the pumped fiuid may flow. A cup-shaped piston 62, which may be formed of a synthetic material, if desired, is slidably mounted on the piston rod above the retainer 58 and a piston movement limiting ring 64 is maintained upon the piston rod within a groove in spaced axial relationship to the ring 56. The piston cup 62 s provided with a clearance 66 around the piston rod whereby the fiuid may fiow through the clearance when the piston rod is being moved downwardly during the retracting stroke, as well as flow around the piston lip. When the piston rod is pulled upwardly, the piston will seat upon the retainer 58, sealing the clearance 66, and permitting the fiuid within the cylinder to be lifted to the chamber 28. Thus, the lost motion connection of the piston upon the piston rod permits the piston and retainer to function as a unidirectional valve to permit low resistance recharging of the cylinder and lifting of the liuid therein, and also renders the piston self-aligning with the cylinder.

A hollow spout support 68 is rotatably received within the opening 18 defined in the mounting body 10. The spout support is of a generally cylindrical configuration, including cylindrical sides in which a groove is defined for receiving an O-ring 70.

The spout support 68 is received within the opening with such clearance as to permit the spout support to be rotatably or swivelably located within the opening, and the O-ring 70 produces a sealing relationship between the mounting body and the spout support at all positions of rotation. The support is formed with a shoulder 72 which cooperates with an annular shoulder 74 defined in the mounting body to limit upward movement of the spout support. The lower edge 76 of the spout support engages a portion of the end of the chamber plate fiange 34, FIG. l, and this relationship prevents downward movement of the spout support within the mounting body.

A passage 78 is defined in the spout support which is in communication with the chamber 28. Perpendicularly related to this passage, a cylindrical bore 80 is formed which intersects the passage and constitutes the spout receiving means. It will be noted that the bore 80 has an axial length greater than its diameter.

A key 82 is defined within the cylindrical bore 80 at the lower region thereof. In the disclosed embodiment, the key 82 consists of a metallic screw positioned within the support having an end 84 which radially projects into the bore 80 adjacent the passage 78. It is possible that key 82 be defined by other means than the disclosed screw. For instance, the key could be molded into the bore or bonded therein.

The spout 86 is preferably formed from a cylindrical tube of noncorrosive, synthetic plastic material and includes an inner end 88 and an outlet end 90. The spout is formed in an offset relationship whereby the operative position of the spout positions the discharge opening end 90 substantially above the elevation of the mounting body 10. The exterior portion of the spout at the inner end 88 is of a cylindrical configuration and of such diameter as to be closely received within the spout support bore 80. This fit is such that the spout is capable of being rotated therein. An annular groove 92 is defined about the spout cylindrical surface for receiving an O-ring 94 to establish a sealing connection with the spout support bore. A second annular groove 96 is defined about the spout end portion in a spaced relationship to the spout end, and is of an axial dimension slightly larger than the axial dimension of the key end 84. An axially extending slot 98 is formed in the spout end portion 88, FIG .4, which is of such a peripheral dimension as to readily receive the key end 84. The relationship of the slot 98 to the configuration of the spout 86 will be later described.

In many installations of a pump in accord with the invention, it is desirable to use a spacer on the mounting body to permit the mounting body to be mounted upon its supporting countertop or panel at an elevated position thereto. For this purpose, an annular spacer 100 is afiixed to the body undersurface 16. The spacer 100 is of a configuration substantially corresponding to the peripheral configuration of the mounting body 10 and includes an inwardly disposed portion 102 defining a planar top surface 104 which is adapted to underlie the undersurface 16. A skirt portion 106 depends downwardly from the portion 102 and terminates in a planar lower edge 108. The vertical dimension of the skirt portion 106 is such that the plane of the lower edge 108 is substantially coincident with the plane of the chamber-defining wall terminating edge 26, or extends therebelow. This relationship is of significance as the spacer edge 108 will constitute the supporting edge for the mounting body when the spacer is employed.

As a feature of the invention lies in the resistance of the pump to corrosion, it is preferred that the basic components, wherever desired, are formed of noncorrosive, synthetic plastic materials. For instance, the mounting body 10, spacer 100, chamber plate 30, fitting 40 and cylinder 38 can be formed of noncorrosive A.B.S. plastic material. The handle 52, spout 86, piston 62 and spout support 68 may be formed of a high strength, easily moldable plastic having excellent wear resistance qualities such as Delrin, manufactured by the Du Pont Company, for instance. Of course, a number of plastic materials may be employed and the above description is not intended to limit the particular material of a specific component. The fixed or sealed plastic components of the pump are, preferably, axed together by solvents to produce watertight and rigid connections where desired. For instance, when it is desired to use spacer 100, the spacer upper surface 104 will be bonded to the body undersurface 16. As previously mentioned, the piston rod 50 will normally be formed of a noncorrosive metal such as aluminum or a stainless alloy. The check valve ball 48 may be of a synthetic plastic or of a stainless metal.

Afiixing of the mounting body to the supporting countertop or panel is accomplished by means of fasteners, suchas screws, extending through countersunk holes 110 defined in the mounting body, FIG. 2. The holes 110 are set inwardly of the peripheral edge 14 and outwardly of the chamber-defining wall portion 24.

Normally, la purchaser of the pump in accord with the invention indicates whether he desires to mount the pump for maximum spout clearance above t'he countertop, as in FIG. 1, or whether he desires the pump to have its minimum vertical height or low silhouette when mounted as shown in FIG. 5. If the first type of installation is requested, the customer is usually supplied with a pump having the spacer 100 afixed to the body undersurface 16, as in FIG. l. If t'he second mode of installation is requested, the spacer 100 is not aixed to the body 10 andthe pump will be installed as in FIG. 5.

When installing the pump utilizing the spacer, it is only necessary to form a cylindrical opening 112 in the countertop or panel 114 of sufficient diameter to receive the cylinder 38. When installing the pump to have its minimum ver-tical height, the opening 116 defined in the countertop or panel 118, FIG. 5, must be of suicient dimension and configuration to permit the chamberdefining wall 24 to be received therein.

The pump is shipped to the customer with the spout 86 removed from the spout support 68. In this manner a concise shipping container may be utilized and by rotating the piston such that the handle 52 engages the spout support 68, the configuration of the container required to package the pump will substantially correspond to the cross-sectional area of the mounting body 10 and spacer 100.

Prior to installing the pump, the assembler inserts the spout end 88 into the bore 80 in such a manner that the axial slot 98 is in alignment with the key end 84, as in FIG. 3. The spout is inserted into bore 80 to the depth wherein the key end is received within the groove 96. This relationship will be indicated by the key end 84 bearing against the wall of the groove 96 furthest from Ithe spout inner end. Thereupon, the operator rotates the spout 180 to its operative position as indicated in full lines in FIG. l. Preferably, the axial slot 98 is located upon the spout end 88, and is related to the-axis of the cylindrical portion -adjacent -the spout .inner end such that the spout must be turned 180 from its operative position, such as represented in the full lines of FIG. 1, to the dotted line position 120 to align the slot 98 with key end 84. Thus, it will be appreciated that the outlet 90 is related to the slot 98 in such a manner that the outlet is not disposed in its normal operative position until a firm locking interconnection between the spout and the spout support is achieved. During nonuse of the pump, it may be desired to minimize the elevation of the spout and, in such instance, the spout may be rotated 90 from the full-lined position of FIG. 1 to the dotted line position 122.

A plastic or rubber hose supply line, not shown, is affixed to the fitting portion 44 which communicates with a water supply tank. Upon reciprocation of the piston rod 50 within the cylinder 38, the water will be drawn from the supply tank into the cylinder, chamber 28, and through the spout support into the spout 86. The fact that the spout support 68 is swivelably mounted upon the body 10 permits the spout to be swung through more than of rotation.
