Powered Nail Extractor

View page

US Patent:

40787664, Mar 14, 1978

Filed:

Apr 11, 1977

Appl. No.:

5/786237

Inventors:

Albert C. Saurwein - Seattle WA

International Classification:

B25C 1100

US Classification:

254 18

Abstract:

A fluid actuated nail extractor includes a pair of jaws pivotally mounted on a reciprocable rod. An impact piston impacting a second rod coupled to the jaws closes the jaws about a nail embedded in a workpiece when the extractor is positioned adjacent the nail. Thereafter, a second piston actuates the reciprocable rod to extract the nail from the workpiece. Pressurized fluid, controlled by a plurality of poppet valves, drives the pistons through a predetermined sequence of operations. The entire sequence of operations is dependent upon the position of a safety valve that is actuated by a push rod having an end located adjacent the jaws. The push rod is actuated only when the nail extractor is positioned adjacent the workpiece, and hence actuating the safety trigger valve so that the operational sequence of the pistons can be initiated.

US Patent:

48486710, Jul 18, 1989

Filed:

Oct 13, 1987

Appl. No.:

7/107414

Inventors:

Albert C. Saurwein - Auburn WA

International Classification:

B05B 1508
B05B 100
F16L 5500
E04B 200

US Classification:

239587

Abstract:

A high pressure water/abrasive jet cutting nozzle has a pair of centering rings that act through body-mounted balls to position a nozzle element-holding collet. The interior surfaces of the centering rings are eccentric with respect to the longitudinal axis of the nozzle assembly so that rotation of a centering ring will cause the nozzle element collet to shift transversely. By rotating one or the other, or both, centering rings the axis of the nozzle element can be adjusted relative to the nozzle jet-forming element so as to align the nozzle element with the water jet.

US Patent:

42655811, May 5, 1981

Filed:

Jul 16, 1979

Appl. No.:

6/057814

Inventors:

Frank E. Ives - Kent WA
Albert C. Saurwein - Seattle WA

Assignee:

Venus Products, Inc. - Kent WA

International Classification:

F04H 622

US Classification:

414228

Abstract:

An automated parking system includes a multi-story tower having a central elevator shaft. The building is substantially circular in cross section and contains a plurality of parking stalls that radiate from the elevator shaft on each of the stories. An elevator mechanism elevates a turntable, rotatably mounted on the elevator mechanism for rotation about a substantially vertical axis, between the several floors of the building. A shuttle travels from the turntable to an entrance ramp on the ground level of the building, moves a vehicle to be parked from the entrance ramp to the turntable, whereupon the elevator and turntable cooperate to deposit the vehicle in a parking stall on one of the several floors. The elevator and turntable mechanism operate in reverse to carry the vehicle from a parking stall to an exit ramp on the ground floor of the building.

US Patent:

48181943, Apr 4, 1989

Filed:

Jun 11, 1987

Appl. No.:

7/060521

Inventors:

Albert C. Saurwein - Auburn WA

International Classification:

F04B 2102

US Classification:

417567

Abstract:

A check valve assembly for fluid pressure-intensifying apparatus of the double-acting type is provided. The assembly has an inner low pressure poppet valve member communicable with the high pressure chamber of fluid pressure-intensifying apparatus, and an outer high pressure poppet valve member communicable with a high pressure fluid outlet line. The check valve assembly is designed for service accessibility without having to dismantle the intensifier.

International Classification:

F04B 910
F15B 1522

US Classification:

Athletic Shoe Sole

US Patent:

40966496, Jun 27, 1978

Filed:

Dec 3, 1976

Appl. No.:

5/747353

Inventors:

Albert C. Saurwein - Seattle WA

International Classification:

A43B 1304

US Classification:

36 32R

Abstract:

An athletic shoe sole has a heel section and a toe section bearing flange-shaped, turf-gripping members. The first gripping member is a generally downwardly and outwardly extending flange that runs around the entire periphery of the sole. The second gripping member is an ovoid-shaped, generally downwardly and outwardly extending toe flange positioned in the toe section of the sole and spaced inwardly from the portion of the peripheral flange on the toe section. The third gripping member is a heel flange extending downwardly and outwardly from the heel section of the shoe and spaced inwardly from the portion of the peripheral flange on the heel section. The rearward portion of the heel flange is arcuate and merges into two generally forwardly extending flange portions that flare outwardly and join with the peripheral flange adjacent the forward end of the heel section. All of the flanges are downwardly convergent and have a bottom edge. The bottom edge of the heel and toe section flanges extends downwardly from the sole a greater distance than does the bottom edge of the peripheral flange.

US Patent:

45260001, Jul 2, 1985

Filed:

Oct 18, 1983

Appl. No.:

6/541827

Inventors:

Albert C. Saurwein - Auburn WA

Assignee:

McCartney Manufacturing Co., Inc. - Baxter Springs KS

International Classification:

F04B 3500
F01L 2504

US Classification:

60540

Abstract:

A first pressure-intensifying apparatus includes a working cylinder having a working piston mounted within it and reciprocally movable by the application of working fluid alternately to opposite sides of the working piston. The working piston in turn drives a high-pressure piston movably mounted within a high-pressure cylinder. The flow of pressurized working fluid to the working cylinder is controlled by a control valve. The control valve receives pressurized fluid from a source of working fluid and directs the fluid to the working cylinder and then back to a working fluid reservoir or tank. The control valve includes a valve body and has a spool movably mounted therein that is movable between a first position in which fluid is directed to one side of the working piston and a second position in which fluid is directed to the other side of the working piston. The spool is designed to maintain a constant volumetric flow of fluid from the source to the tank at the first and second positions and all positions in between. In order to accomplish this, a series of slots are formed in the surface of the spool to divide the flow of fluid between the source and the working cylinder and the source and the tank at the intermediate positions of the spool in a predetermined fashion.
