Fluid dispensing device

Claim 3

The device of claim 1 in which the sleeve is divided longitudinally to define adjacent end portions adapted to be overlapped for compressible receipt of the sleeve internally of the tubular member and alternatively separated for tensioned receipt exteriorly of said member remote from the compressible end portion.

Claim 4

The device of claim 2 in which the compressible end portion of the tubular member has a longitudinal slot therein to accommodate compressible insertion of said member in the passage of the mounting plate.

Claim 5

The improvement of claim 2 in which a plug is selectively adapted to be inserted in the upper end of said tube to preclude discharge of fluid from the riser.

Claim 6

In a fluid dispensing device for an irrigation system, the device having a riser with a lower end in communication with the system, an opposite upper open end and an orifice extending laterally through the riser intermediate the upper and lower ends adapted to release the fluid received by the riser from the system, an improvement comprising an elongated, substantially cylindrical tube having upper and lower ends and a slot in the tube extending from the lower end thereof longitudinally of the tube to a point in spaced relation to the lower end; a substantially cylindrical control sleeve, having a diameter substantially equal to that of the tube, divided longitudinally to form a pair of adjacent end portions adapted for overlapping engagement for compressed insertion of the sleeve in the tube at its upper end and alternatively separation for tensioned mounting exteriorly of said tube; and a mounting plate borne by the riser internally thereof intermediate the lower end and the orifice and having a substantially cylindrical passage with aN internal diameter smaller than the exterior diameter of the tube and adapted to receive the lower end of said tube in compressibly locking relation thereto in upright relation in the riser with the sleeve disposed above the mounting plate for endward adjustment in the tube to regulate the hydrostatic head of fluid pressure required in the system to discharge from the riser.

Claim 7

In a fluid dispensing device for an irrigation system, the device having a riser with a lower end in communication with the system, an opposite upper open end and an orifice extending laterally through the riser intermediate the upper and lower ends adapted to release the fluid received by the riser from the system, an improvement comprising an elongated, substantially cylindrical tube having upper and lower ends and a slot in the tube extending from the lower end thereof longitudinally of the tube to a point in spaced relation to the lower end; a substantially cylindrical control sleeve, having a diameter substantially equal to that of the tube, divided longitudinally to form a pair of adjacent end portions adapted for overlapping engagement for compressed insertion of the sleeve in the tube at its upper end and alternatively separation for tensioned mounting exteriorly of said tube; and a mounting plate borne by the riser internally thereof intermediate the lower end and the orifice and having a substantially cylindrical passage with aN internal diameter smaller than the exterior diameter of the tube and adapted to receive the lower end of said tube in compressibly locking relation thereto in upright relation in the riser with the sleeve disposed above the mounting plate for endward adjustment in the tube to regulate the hydrostatic head of fluid pressure required in the system to discharge from the riser.

Claim 8

A fluid flow regulating device comprising a substantially erect riser; a partition disposed transversely in the riser having a passage therethrough of rigidly limited dimensions; a tubular member extended through the passage having an intake end below the partition, an outlet end above the partition, and an intermediate portion shaped to correspond to the passage and of slightly greater dimensions than the passage, said tubular member being slotted longitudinally from its intake end to a position adjacent to the partition for resilient constriction and being wedged tightly downwardly into the passage; and a sleeve slidably telescopically mounted on the outlet end of the tubular member.

Claim 9

A fluid flow regulating device comprising a substantially erect riser; a partition disposed transversely in the riser having a passage therethrough of rigidly limited dimensions; a tubular member extended through the passage having an intake end below the partition, an outlet end above the partition, and an intermediate portion shaped to correspond to the passage and of slightly greater dimensions than the passage, said tubular member being slotted longitudinally from its intake end to a position adjacent to the partition for resilient constriction and being wedged tightly downwardly into the passage; and a sleeve slidably telescopically mounted on the outlet end of the tubular member.

Claim 10

The device of claim 6 in which the tubular member and the sleeve are of substantially the same diameter when unstressed and one thereof is longitudinally slotted, resiliently deformed and frictionally engaged in telescopic association with the other.

Claim 11

A fluid flow regulating device for connection to a source of fluid comprising means having a passage therethrough of fixed transverse dimensions adapted to be connected to said source with the passage in fluid communication therewith; a tubular member having a longitudinally slotted end portion compressed into the passage to mount said member in a substantially erect attitude in said means; and fluid conducting means having an upper discharge end and telescopically mounted by the tubular member at a position remote from said slotted end portion for endward adjustment therein to regulate the height of the discharge end of the conducting means.

Claim 12

A fluid flow regulating device for connection to a source of fluid comprising means having a passage therethrough of fixed transverse dimensions adapted to be connected to said source with the passage in fluid communication therewith; a tubular member having a longitudinally slotted end portion compressed into the passage to mount said member in a substantially erect attitude in said means; and fluid conducting means having an upper discharge end and telescopically mounted by the tubular member at a position remote from said slotted end portion for endward adjustment therein to regulate the height of the discharge end of the conducting means.

Claim 13

The device of claim 8 in which said fluid conducting means includes a sleeve telescopically mounted on the tubular member and upwardly endwardly extended therefrom.

Claim 14

The device of claim 8 including a plug adapted for insertion in the upper end of said tubular member to preclude the discharge of fluid through said member from the source.
