Filed:

Feb 1, 1991

Appl. No.:

7/649597

Inventors:

John H. Wheeler - Dallas TX
Jimmy P. Frentzos - Plantation FL

Assignee:

Texacone, Inc. - Mesquite TX

International Classification:

F16L 5502

US Classification:

181233

Abstract:

A muffler for reducing fluid flow noise in a hydraulic system comprises a cylindrical elastomer insert having multiple reinforced flow ports with different diameter porting, internal air chambers, and cast from an elastomer mixed with hollow glass spheres to form an insert of 40 percent air by volume. The insert is placed within a housing and connected to the hydraulic pipe assembly for receiving fluid under pressure and diverting it through the multiple flow ports of the insert wherein flow sounds, pump surges, and flushing noises of the hydraulic system are muffled by the disruption of the flow through the flow ports, the absorption by the internal air chambers, and the absorption by microspheres created by the hollow glass spheres in the elastomer insert.

John H. Wheeler - Dallas TX

Assignee:

Texacone Company - Mesquite TX

International Classification:

B32B 702

US Classification:

428217

Abstract:

A polymer seal and method of making same consisting of a combination of pre-polymers cured and bonded together to form a single multi-layered seal of varying hardness with at least one pre-polymer being a polyester-based pre-polymer and at least one pre-polymer being a polyether-based pre-polymer. The different pre-polymers, upon curing, yield 80 to 90 shore A and 80 to 90 shore D hardness urethanes respectively.

Appl. No.:

6/185205

Inventors:

John H. Wheeler - Dallas TX

Assignee:

The Texacone Company - Dallas TX

International Classification:

F16J 1524
F16J 1532

US Classification:

277211

Abstract:

An elastomeric O-ring seal (10) for sealing between a housing (20) and a shaft (22). The seal (10) defines an inner sealing surface (12) and an outer sealing surface (14) having a generally uniform non-deformed radius of curvature in cross section. An upper protrusion (16) and a lower protrusion (18) extend outward of a circle defined by this radius in cross section to prevent the seal (10) from rolling when placed in sealing engagement with the housing (20) and shaft (22). This reduces the wear on the seal (10) and permits a longer surface life.

Appl. No.:

5/858640

Inventors:

John H. Wheeler - Dallas TX

Assignee:

The Texacone Company - Dallas TX

International Classification:

B66B 712

US Classification:

187 1R

Abstract:

An apparatus is provided for continuously cleaning rust and other corrosion from elevator guide rails and for filling pits, joints and other irregular areas in the rails. A plurality of guide brackets are mounted on the car for contact with the rail. Each guide bracket includes a bushing insert for contact with surfaces of the guide rail. In one embodiment, the insert is made from an elastomeric material with particles of bronze or brass embedded therein. In a second embodiment, the insert has lead embedded therein. Where the insert has bronze or brass embedded therein, the sliding of the insert relative to the walls of the guide rails acts as an abrasive cleaner to remove rust, corrosion and dirt particles from the surface of the rails. Where the insert has lead embedded therein, contact between the insert and the rail results in the transfer of lead to the rails to fill pits, joint areas and irregularities in the rails. The inserts are formed with a plurality of ribs in which some are inclined upwardly while others are inclined downwardly from the longitudinal axis of the rail.

International Classification:

B24B 100

US Classification:

51289R

Abstract:

A sleeve assembly for sanding, rust removing, and pit filling on a piston rod of a hydraulic cylinder or the like includes a sanding component, a rust removing component and a pit filling component. The sanding component comprises a rigid annular outer member, a resilient annular intermediate member adhesively secured to the inner surface of the outer member, and an abrasive annular inner member adhesively secured to the inner surface of the intermediate member and in interference contact with the piston rod. The rust removing component comprises an annular upper ring member composed of a rigid material and an elastomeric annular lower C-ring member having brass or bronze particles imbedded therein. The pit filling component comprises an annular upper ring member composed of a rigid material and an elastomeric annular lower C-ring member having lead particles imbedded therein. Clamp means releasably engages the members of each of the components about the piston rod.

International Classification:

F16J 1532

US Classification:

277205

Abstract:

A seal for use in the gear housing (52) of an elevator hoist drive mechanism (10) is provided. The first embodiment, seal (98), is generally formed of an annular body of elastomeric material having an outer sealing section (102) with first sealing surface (104) for engagement with the inner rim (86 and 88) of gear housing (52), an inner sealing section (106) with second sealing surface (108) for engagement with cylindrical connecting drive shaft (69) and a bonding wall (100) for securing seal (98) on gear housing (52). Sections (102 and 106) are separated by a V-shape groove (124) to insure independent resilence of the sections. Seal (98) is split to form ends (112 and 114) to simplify installation. The second embodiment, seal (132), is generally formed of an annular body of elastomeric material having a fabric coating. Seal (132) has a compression surface (140) deformably securing the seal to gear housing (52), and a shaft sealing surface (142) with shaft sealing lip (144) for sealing engagement with cylindrical connecting drive shaft (69).

Abstract:

A sleeve assembly for sanding a piston rod of a hydraulic cylinder or the like comprises a rigid annular outer member, a resilient annular intermediate member adhesively secured to the inner surface of the outer member, and an abrasive annular inner member adhesively secured to the inner surface of the intermediate member for interference contact with the piston rod. The sections of the annular members each have complementary nonaxial end configurations to prevent scoring of the piston rod during axial movement. Clamp means releasably engages the members around the piston rod. In some embodiments, bracket or angle bar means are utilized to releasably secure the sleeve assembly to structure at the end of the cylinder. In another embodiment, the sleeve assembly is releasably clamped directly around the end of the hydraulic cylinder.
