Filed:

May 22, 1991

Appl. No.:

7/703897

Inventors:

Wilson V. Cochran - Riverside CA

Stephen L. Tyler - Diamond Bar CA

Assignee:

The Toro Company - Minneapolis MN

International Classification:

B05B 130

US Classification:

239583

Abstract:

An adjustable arc sprinkler nozzle comprises a nozzle body which has a plurality of radial channels for forming radial streams out of water flowing into the nozzle from a sprinkler body to which the nozzle is joined. A crown shaped deflector member includes a plurality of vertically extending fingers which operatively coact with the radial nozzle channels to restrict the amount of water flowing therethrough. A selectively operable adjusting member is cooperatively engaged with the deflecting member for moving the deflecting member vertically relative to the nozzle body to vary the position of the fingers relative to the channels to change the amount of water restriction imposed by the fingers on the water flowing through the channels, whereby the throw radius is selectively adjusted by vertical movement of the deflecting member.

Assignee:

The Toro Company - Minneapolis MN

International Classification:

B05B 1510

US Classification:

239205

Abstract:

An improved adjustable arc sprinkler head (2) includes a pop-up riser (20). Riser (20) comprises a housing (26) having a rotatable nozzle assembly (28) carried adjacent the top thereof. A driven gear (50) is fixed to nozzle assembly (28) and cooperates with a drive train contained inside a motor compartment (30) in riser housing (26). An adjustment member (58) is normally rotatably locked to driven gear (50) by matching serrations (69) and (70). Nozzle assembly (28) is moveable downwardly relative to riser housing (26) sufficiently far to disengage serrations (69) and (70) and allow driven gear (50) to be rotated relative to adjustment member (58). This rotation varies the circumferential distance between two stops (56) and (64) carried on driven gear (50) and adjustment member (58) to vary the angular extent of the arc segment being watered by sprinkler head (2).

Appl. No.:

6/873122

Inventors:

Jon A. Bivens - Upland CA
Stephen L. Tyler - Diamond Bar CA

Assignee:

The Toro Company - Minneapolis MN

International Classification:

B05B 1510

US Classification:

239204

Abstract:

An improved sprinkler head (2) having a hollow housing (4) has a fluid inlet (5) for admitting water into housing (2). A drain valve (40) comprises an elongated flexible nipple (34) having an open upper end (35) and a closed lower end (36) having a normally closed drain passage (42). Nipple (34) is mounted in any drain port in housing (4). Whenever fluid pressures inside housing (4) increase above a first level, nipple (34) will have its walls bowed outwardly until the drain passage (42) is opened. Preferably, drain valve (40) is part of a check valve (30) which incorporates into it the structure of nipple (34).

Appl. No.:

7/537916

Glendale Grizzle - Corona CA
Stephen L. Tyler - Diamond Bar CA

James W. Zimmerman - Walnut CA

Assignee:

The Toro Company - Minneapolis MN

International Classification:

F16K 2500
F16K 31126

US Classification:

251 611

Abstract:

A fluid flow control valve has a resilient diaphragm that engages a valve seat. A line contact is formed between the diaphragm and the valve seat at or closely adjacent the outer diameter of the valve seat. This enhances the ability of the valve to seal under low fluid pressures. The diaphragm is reinforced by a plastic reinforcing member which is formed separately from the diaphragm. The reinforcing member and the diaphragm are inserted together in a press fit, and barbed posts on the reinforcing member hold the two together.
