Thermal Contraction Control Apparatus For Hydraulic Cylinders

US Patent:
6634172, Oct 21, 2003
Filed:
Feb 26, 2002
Appl. No.:
10/082217
Inventors:
Stephen J. Schoonmaker - Chambersburg PA
Jeffrey L. Addleman - Chambersburg PA
Assignee:
Grove U.S. LLC - Shady Grove PA
International Classification:
F15B 1520
US Classification:
60329, 60399, 60442, 91361
Abstract:
A method and apparatus for operating a load lifting device to move a load and hold the load steady is disclosed. In the conventional arts, a lifted or lowered suspended load had a tendency to move from its desired position, as hydraulic fluid in the lifting system cooled, e. g. a stick slip condition. The present invention monitors a fluid pressure in the lifting system and compensates the fluid pressure to accommodate any pressure drop due to fluid cooling. Thereby, the load can be effectively held steady at a desired position, and the stick slip condition can be avoided.

Tow Truck With Underlift Control

US Patent:
2011017, Jul 14, 2011
Filed:
Mar 21, 2011
Appl. No.:
13/053068

414563, 701 36
Abstract:
A vehicle includes a chassis and an underlift supported by the chassis. The underlift has a boom and a vehicle engaging device coupled to the boom. The vehicle also includes an operator control coupled to the underlift that allows the operator to command the boom to lift and tilt to various positions and a control system that restricts movement of the boom when the boom reaches a predetermined position as the boom is being lowered to a loading position. The control system allows the operator to move the boom after the predetermined position is reached such that the boom may continue movement in a downward direction.

2012012, May 17, 2012
Filed:
Nov 17, 2010
Appl. No.:
12/948076
Inventors:
Sanjeev T. Kuriakose - Shippensburg PA, US
Jeffrey L. Addleman - Chambersburg PA, US
International Classification:
B60P 1/16, B60P 1/04
US Classification:
414477
Abstract:
A rollback carrier includes a vehicle chassis, a truck bed assembly supported on the vehicle chassis and displaceable between a transport position and a loading position, and a front actuating arm acting between the truck bed assembly and the vehicle chassis. The front actuating arm dampens a tilt position of the truck bed relative to the vehicle chassis.

Forklift Variable Reach Mechanism

US Patent:
4718814, Jan 12, 1988
Filed:
Dec 11, 1986
Appl. No.:
6/940734
Inventors:
Jeffrey L. Addleman - Chambersburg PA
Assignee:
Kidde, Inc. - Saddle Brook NJ
International Classification:
B66F 914
US Classification:
414705
Abstract:
A mechanism for use on a boom-type vehicle includes load lifting forks carried by a low profile twist-resistant carriage which is one link in a low profile parallelogram linkage attached to a fly section of the boom and maintained level in all positions of the boom by a slave cylinder connected between the boom and a slave link which constitutes a member of the parallelogram linkage. The mechanism can be adjusted to many positions while automatically maintaining the relative position of the forks with respect to the vehicle frame for any boom angle. The mechanism can be adjusted to provide a long reach over or under obstructions in order to remove or place a load. It may also engage loads below ground level. Load pick-up or placement can be performed in confined areas which are unreachable by conventional forklift trucks.

Vibratory Mechanism

US Patent:
4454780, Jun 19, 1984
Filed:
Jul 6, 1981
Appl. No.:
6/280939
Inventors:
Robert F. Goehler - Greencastle PA
Jeffrey L. Addleman - Chambersburg PA
Dana R. Rotz - Shippensburg PA
Assignee:
Ingersoll-Rand Company - Woodcliff Lake NJ
International Classification:
E01C 1938, F16H 3310
US Classification:
74 87
Abstract:
The mechanism, designed especially for use in an earth compacting drum, comprises a pair of concentrically-arranged, eccentrically-weighted elements, which are rotated in unison by means of a hydraulic motor. The mechanism is housed within an earth compacting drum, and the one eccentrically-weighted element is translatable, axially, and disengageable from a splined coupling, in order that it may be indexed to different rotary positions relative to the other eccentrically-weighted element. In this manner, vibratory amplitudes may be increased or decreased.
