US Patent:

58604464, Jan 19, 1999

Filed:

Mar 12, 1996

Appl. No.:

8/614277

Inventors:

Christopher C. Hunt - Newberg OR

Assignee:

Climax Portable Machine Tools, Inc. - Newberg OR

International Classification:

F16K 17164

US Classification:

137464

Abstract:

A method and apparatus for safely controlling fluid flow comprises a safety control valve that automatically stops fluid flow upon a fluid pressure failure, requires two-handed manual operation to open the valve, and the valve being biased to prevent being left in the open position in the absence of fluid pressure. The safety control valve comprises a valve body that coaxially receives therein a slidable spool manually operable in an axial direction between a closed valve position and an open valve position. The valve further comprises a spring and a spring biased coaxial safety piston capable of axial movement along the spool and being pneumatically connected to a fluid supply line. In the absence of fluid pressure, the spring biases a safety piston against a contact surface of the spool so as to bias the spool into the closed position thereby preventing fluid flow through the valve. In the presence of a sufficient fluid pressure in the fluid supply line, the fluid pressure biases the safety piston against the spring and away from the contact surface of the spool so as to prevent movement of the spool between the open and closed positions.

Christopher Hunt - Newberg OR

Assignee:

Climax Portable Machine Tools, Inc. - Newberg OR

International Classification:

B23B 324

US Classification:

82113

Abstract:

A portable flange facer may be used to machine flange faces without removing the pipe from its installation thereby avoiding extensive disassembly and downtime. A stationary spindle, mounted centrally within the pipe bore, provides a structure about which a main body rotates. A motor, mounted upon the main body, and a gear means, coupling the motor to the stationary spindle, are used to rotate the main body about the spindle. A cutting element, mounted upon a turning bar slidable within the main body, may be moved radially inwardly and outwardly by manual or automatic means. The flange facer may be used to resurface a flange face or to form circular grooves therein.

Christopher C. Hunt - Newberg OR
Paul M. Strait - Newberg OR

Assignee:

Climax Manufacturing Company - Newberg OR

International Classification:

B23B 516

US Classification:

82 4R

Abstract:

A portable lathe device is modular in character and can be employed for flange facing, line boring or other purposes. The spindle carrying the tool means is readily axially adjustable, and the radial feed rate for a facing head tool carrier is infinitely variable and reversable.

Climax Portable Machine Tools, Inc. - Newberg OR

International Classification:

B23C 120

US Classification:

409178

Abstract:

A portable machine tool includes a bed and a cantilevered ram mounted for movement in a longitudinal direction along the ways thereof. A dovetail slide on a side of the ram movably supports a rotatable spindle unit capable of machining in the transverse direction completely crossways of the bed.

International Classification:

B60C 23/12
B60B 3/10
B60B 21/12

Abstract:

A wheel for an air maintenance tire system is provided. The air maintenance tire system includes at least one pump and a regulator. The wheel includes a body that is formed with an axially-extending wall, a pair of flanges, and a pair of bead mounting areas. Each bead mounting area is disposed axially inwardly proximate a respective one of the flanges. The axially-extending wall is formed with an AMT mounting channel. The AMT mounting channel extends circumferentially about the wheel approximately mid-way between the flanges and is defined by a first adjacent wall, a second adjacent wall, and a base. Mounting surfaces are formed in or adjacent the AMT mounting channel, so that the at least one pump is mounted in the AMT mounting channel radially inwardly of the bead mounting areas.

Abstract:

An air maintenance tire system and method in accordance with the present invention includes an air pumping mechanism configured to maintain air pressure within a first tire and a second tire in a dual tire arrangement. The system includes a control valve assembly attached to an elongate valve stem projecting from a rim of a first tandem tire, and a one-way valve carrying connecting tube from a sidewall air pumping passageway within a sidewall of the first tire. The control valve assembly further includes first and second outlet tubes connected to the elongate valve stem to selectively pass pressurized air into the tire cavities of both tandem mounted tires on an as-needed basis.
