Pre-Load Adjustment For Span Lock System

US Patent:
6588041, Jul 8, 2003
Filed:
Feb 11, 2002
Appl. No.:
10/073510
Inventors:
Robert L. Cragg - Maple Glen PA
Assignee:
Steward Machine Co., Inc. - North Birmingham AL
International Classification:
E01D 1508
US Classification:
14 46, 14 41
Abstract:
A drawbridge span lock system in which a locking bar longitudinally slides between wear shoes in each of guide and socket assemblies. The wear shoes are pre-loaded to a selected level by springs within the assemblies to maintain continuous contact of the shoes with the locking bar under no-load operating conditions of the bridge. Threaded adjusting carriers externally accessible in each assembly enable the springs to be precisely pre-loaded to any level within a design range.

Static Stabilizers For Bridges

US Patent:
7020924, Apr 4, 2006
Filed:
Mar 29, 2004
Appl. No.:
10/812120
Inventors:
Robert L. Cragg - Maple Glen PA, US
Assignee:
Steward Machine Co., Inc. - Birmingham AL
International Classification:
E01D 15/06
US Classification:
14 35, 14 31, 14 36
Abstract:
An adjustable static stabilizer used to ameliorate shock loading. The static stabilizer has a housing forming a chamber and an upwardly-open cylindrical carrier moveably mounted in the chamber. A plurality of spring washers are mounted in the carrier, and a shoe cap extends transverse to the carrier for engaging the spring washers therein. A tie rod interconnects the shoe cap and the carrier for displacement of the shoe cap relative to the housing, and a threaded means is disposed between the housing and the carrier for rotatably mounting the carrier in the housing which is operable upon rotation of the shoe cap relative to the housing to enable the overall height of the stabilizer to be adjusted.

Wear Resisting Span Lock System

US Patent:
8590086, Nov 26, 2013
Filed:
Apr 11, 2013
Appl. No.:
13/860636
Inventors:
Robert L. Cragg - Maple Glen PA, US
Assignee:
Steward Machine Co., Inc. - Birmingham AL
International Classification:
E01D 15/06
US Classification:
14 41, 14 46
Abstract:
A wear resisting span lock system for bascule bridges includes a normally-inactive hydraulic lockbar shoe expander operable to minimize sliding engagement of the lockbar with its guiding and receiving shoes only during bridge opening and closing operations.

Energy-Absorbing Span Lock System For Drawbridges

US Patent:
5327605, Jul 12, 1994
Filed:
Mar 31, 1993
Appl. No.:
8/040420
Inventors:
Robert L. Cragg - Maple Glen PA
Assignee:
Steward Machine Co., Inc. - Birmingham AL
International Classification:
E01D 1508
US Classification:
14 41
Abstract:
An energy absorbing span lock system for drawbridges, such as a double-leaf bascule leaf span. A retractable and extendible connector mounted on one leaf of the span engages a receiver on the other leaf. Resilient energy absorbing shoes in the receiver accept the connector and allow relative deflection between the leaf ends caused by vehicular traffic.
