6 Claims.

This invention relates to portable fountains, and more particularly to fountains of the character which are adapted to be .placed upon tables or the like for decorative and air conditioning purposes.

The principal object of the present invention is to provide a fountain having a multiplicity of jets of fluid projected upwardly with collecting structure interposed between the jet and a vessel above which the collecting means is supported.

The present invention contemplates, in a portable fountain, improved means for supporting the spray head, the pump and motor, and the collecting structure.

The present invention contemplates, in a portable fountain, improved means for protecting the electric motor employed therewith.

The present invention further contemplates the provision of an improved shield, which conceals the mechanism from the eye, but aflords an enlarged chamber for the air required for cooling the motor.

The present invention further contemplates the provision of improved mounting means for the jet head in a portable fountain.

The invention further contemplates improved structure which is also ornamental in character for catching the falling water and reducing the likelihood of splashing.

The present invention further contemplates an improved spray head with which a more attractive fountain or spray is obtained.

The present invention further contemplates the provision of a bushing, which permits an improved regulation of the spray height.

Referring to the drawing which illustrates, merely by way of example, a suitable embodiment of the invention,

Figure 1 is a vertical section;

Figure 2 is a plan view with part broken away;

Figure 3 is an underside plan view of the pump, part of the casing being broken away to show the interior;

Figure 4 is a fragmentary vertical section on an enlarged scale showing the spray head and associated structure; and

Figure 5 is a horizontal section on the line 55 of Figure 4.

Similar numerals refer to similar parts throughout the several views.

In the example illustrated, the fountain includes a large lower bowl 9 supported on suitable feet l0 projecting downwardly from the lower side and provided near the central portion thereof with a vertically extending pipe H secured 2 thereto in fluid-tight relationship. The pipe II serves to form a passage for the lead wires I2 for the motor, as hereinafter explained.

A fountain assembly I3 is provided which is adapted to be positioned at the central of the bowl 9 and be supported thereby. The fountain assembly l3 includes a lower plate l4 having a plurality of feet It of rubber or similar material secured thereto and below the plate M a rotary pump casing I6 is mounted. A pump rotor I8 is provided within the casing I6. The plate 14 has a pump inlet I! through which a pump rotor shaft 19 extends, and also has a fluid delivery pipe 20 extending upwardly, as hereinafter explained.

A cylindrical screen 2| is provided which is adapted to surround the lower part of the fountain; assembly l3 and rest on the bowl 9 for preventing access of solid material to the pump inlet ll.

A pair of vertical posts 22 are secured to the plate I l and support an electric motor 23, to which the lead Wires l2 are connected, for operating the pump rotor shaft 59. The top of the motor 23 has a bracket 24 secured thereto and held in position by means of nuts 25. The bracket 24 has a bushing 26 secured thereto and extending therethrough, and the fluid delivery pipe 20 is connected to the interior of the lower portion of the bushing 25. The portion of the bushing 26 extending above the bracket 24 is threaded on the exterior thereof as at 21. The bushing 26 has a metallic washer 28 mounted thereon immediately above the bracket 24, and above the washer 28, one or more rubber washers 29. A downwardly extending substantially semi spherical casing 30, preferably of metal or other opaque material, is provided for protecting the motor 23 and preventing the access of water thereto. The casing 30 is mounted on the bushing 26 which extends upwardly through the central part of the casing 39. The casing 30 and the pipe H are preferably proportioned so that the lower edge of the casing 30 is a short distance below the upper extremity of the pipe II.

A skirt 3| is provided and is also carried on the bushing 26 and may, if desired, be of transparent synthetic plastic material. The skirt 3i preferably has a depressed portion 32, for collecting falling water, surrounded by a rim 33 over which the water is adapted to flow for return to the bowl 9. The bushing 26, also has mounted thereon, above the skirt 3i, one or more petallike assemblies 34 and 35 for reducing the tendency to splashing, The outer assembly 34, as

illustrated, includes the provision of a plurality of upwardly extending petals 36 with the interiors concaved, the petals 35 being separated by cutaway portions 37 to permit of fluid discharge. The inner assembly 35 is similar to the outer assembly 34, but the petals 38 are disposed in a position more closely approaching the vertical and with the petals 38 in overlapped relationship at their base portions. The openings between the petals 3'8 permit of the discharge of fluid.

On the upper end of the bushing 26 and in contact with the upper face of the interior petal assembly 35, a rubber washer 39 is provided with which a metal washer (it is in engagement, .and a nut 4| in engagement with the threads 21 on the bushing 26 is provided for holding the washer ii} in engagement with the washer 39 so that the casing 30, the skirt BI and the petal assemblies 34 and 35 are held in assembled relationship.

The nut ll is provided on the exterior thereof The spray head d4 preferably ways are available, between the flattened portions 62 and the threaded interior of the spray headid, for the discharge of apart of the water delivered to the interior "of the 'spray head dd. The height of the spray may thus be regulated by :adjustment of the spray head to vary the size of these discharge passageways.

Upon the rotation of the motor 23 the Water delivered by the pump rotor 58 to the discharge pipe 29 and therefrom to the bushing 23 is directed through and by the openings 45 in the spray head The inner row oi petals 33 serves to confine the spray from the openings 45 and prevent sidewise delivery thereof. As the water falls from the spray, it is caught in part by the inner ring of petals 38 and in part by the outer ring of petals 35 which collect the down flowing or falling fluid for delivery to the skirt 3 l. The-skirt 31 also acts as a collector and the water collected in the depressed portion 32, as well as the water delivered thereto, flows over the rim 33 and is returned to the bowl 9 .for re-circulation.

The screen 25 prevents the access of any vegetable or other material which might tend to interfere with the proper action of the pump 18, so that, if desired, the fountain may also be used with living floral displays.

The interior space within the casing 38 and above the level or" the pipe I l provides an air space for the cooling of the motor '23, and the air confined between the skirt '3! and the casing 313 and cooled b the passage of fluid downwardly on the exterior of the skirt 3! also aids in the cooling of the motor 23. The supporting or" the entire fountain assembly 53 on the feet l greatly facilitates the setting up of the fountain and eliminates the necessity for making any separate leveling or other adjustments.
