Filed:

Dec 20, 2004

Appl. No.:

11/025321

Inventors:

David J. McLeod - Auburn WA, US

International Classification:

F04B 17/00
F01C 1/10

US Classification:

417360, 418 48

Abstract:

A knockdown pump containment assembly for supporting a stator that employs a rotor therein. The pump containment assembly comprises a removable pump housing that defines a containment chamber for receiving, containing and directing the flow of a liquid material. The pump housing also includes an inlet port disposed for directing the flow of liquid material into the containment chamber, and an exit port for directing the flow of liquid material out of the containment chamber, into a stator. The pump containment assembly also includes a pump housing base provided for releasably receiving and supporting portions of the pump housing, and a pump housing retainer designed to releasably engage with the pump housing base to releasably secure the pump housing to the pump housing base.

International Classification:

B05B 9/043

US Classification:

239379, 239602, 417234, 464161

Abstract:

A connecting rod for coupling to a mating socket or to a coupler that includes a shaft having a longitudinal axis, a first end, and a second end, at least one of the first and second ends of the shaft having a substantially convex end face that is preferably arcuate or hemispherical in shape; and a spline formed on at least one of the first and second ends of the shaft, the spline having at least two projections that extend from the shaft to be substantially parallel to the longitudinal axis of the shaft, the projections contoured to accommodate universal movement of the shaft relative to the socket. The spline projections may be contoured to taper into the convex or hemispherical end face of the shaft.

Appl. No.:

9/032255

Inventors:

David J. McLeod - Redmond WA

International Classification:

A01C 2300
B05B 900

US Classification:

239662

Abstract:

The invention is a compact, self-contained, portable, electrically powered, knockdown spray application machine/system for spraying liquid material on to surfaces. The spray system comprises a frame with wheels for supporting and transporting the components thereof. The spray system is powered by an electrically activated motor which includes a motor drive shaft disposed about a motor drive shaft axis. Attached to the motor is a gear reducer having a driven end and a drive end wherein the driven end is configured to receive and engage the motor drive shaft. The drive end includes a gear reducer drive shaft that rotates responsive to electrical activation of the motor. Coupled directly to the drive end of the gear reducer is a pump comprising a pump housing. The pump housing is shaped to define a containment chamber for receiving and containing liquid material therein. The pump housing also defines an inlet port for receiving and directing liquid material into the containment chamber.
