Controller For A Compacting Vehicle Wetting System

US Patent:
6827524, Dec 7, 2004
Filed:
Jul 26, 2002
Appl. No.:
10/205872
Inventors:
Kenneth E. Gasper - Chambersburg PA
Steve Kunkel Yates - Scotland PA
Chad L. Fluent - St. Thomas PA
Assignee:
Ingersoll-Rand Company - Montvale NJ
International Classification:
E01D 1926
US Classification:
404129, 404122
Abstract:
A controller is for a vehicle wetting system including a fluid supply and a delivery line having an inlet connected with the supply and an outlet located to direct fluid onto a compacting drum. The controller includes a regulator configured to adjust a fluid flow rate through the outlet. A speed sensor connected with the vehicle senses vehicle speed. Further, a logic circuit connected with the sensor and the regulator automatically operates the regulator such that the regulator adjusts the flow rate to be generally proportional to the vehicle speed. Alternatively, the logic circuit permits flow through the outlet for a predetermined drum displacement and alternately interrupts flow for a predetermined period of time. The regulator is either a shunt line and a valve adjusting flow through the shunt line to adjust flow through the outlet or a pump regulator controlling flow from a pump in the delivery line.

Speed Controlled Eccentric Assembly

US Patent:
6585450, Jul 1, 2003
Filed:
Jul 10, 2001
Appl. No.:
09/901840
Inventors:
Kent Meyers - Chambersburg PA
Steve K. Yates - Scotland PA
Assignee:
Ingersoll-Rand Company
International Classification:
E01C 1926
US Classification:
404117, 404122, 404130
Abstract:
The eccentric assembly includes a tubular section, an eccentric weight, and a counterweight. The eccentric weight is mounted within the tubular section such that as a motor rotates the eccentric assembly, the eccentric weight generates vibrations that are transferred to the drum assembly of the vibration compacting machine. The counterweight is slidably coupled to the eccentric weight and moves between a first position where the counterweight contacts the eccentric weight and a second position where the counterweight contacts the tubular section.

Eccentric Assembly With Eccentric Weights That Have A Speed Dependent Phased Relationship

US Patent:
6516679, Feb 11, 2003
Filed:
Jan 29, 2001
Appl. No.:
09/771824
Inventors:
Steve K. Yates - Scotland PA
Vern E. Martin - Shippensburg PA
Assignee:
Ingersoll-Rand Company - Woodcliff Lake NJ
International Classification:
F16H 3300
US Classification:
74 87, 74 61, 404117
Abstract:
The eccentric assembly includes a shaft, first and second eccentric weights, and a member. The first and second eccentric weights are rotatably coupled to the shaft such that they generate vibrations which are transferred to the drum assembly of the vibration compacting machine when the shaft is rotated by a motor. The eccentric weights are also coupled to the shaft by the member which moves the eccentric weights between a first position where the eccentric weights are in phase and a second position where the eccentric weights are out-of-phase. When the eccentric weights are in phase the eccentric assembly generates a maximum moment of eccentricity about the shaft. As the rotational speed of the shaft increases to generate higher frequency vibrations, the eccentric weights move more out of phase reducing the moment of eccentricity generated by the rotating shaft.

Eccentric-Weight Subassembly, And In Combination With An Earth Compactor Drum

US Patent:
4749305, Jun 7, 1988
Filed:
Aug 31, 1987
Appl. No.:
7/090910
Inventors:
Samuel K. Brown - Greencastle PA
Steve K. Yates - Scotland PA
Assignee:
Ingersoll-Rand Company - Woodcliff Lake NJ
International Classification:
E01C 1938
US Classification:
404117
Abstract:
The subassembly comprises a shaft having an eccentrically-weighted portion journalled in a tube which also has an eccentrically-weighted portion. The tube has an abutment therein which prevents full rotation of the tube relative to the shaft. With rotation of the tube in one direction, its abutment, at one side, comes into engagement with the eccentrically-weighted portion of the shaft and, consequently, both portions are in proximity and radially aligned to produce a maximum, oscillatory vibration. Tube rotation in the opposite direction causes the shaft portion to engage the other side of the abutment and, consequently, the portions are in opposite, radial dispositions, and produce a minimum, oscillatory vibration.

Support For A Portable Instrument Control Box

US Patent:
D364796, Dec 5, 1995
Filed:
Nov 9, 1994

Axle Stabilization System

US Patent:
2002009, Jul 18, 2002
Filed:
Jan 15, 2001
Appl. No.:
09/760177
Inventors:
Michael Scotese - Carlisle PA, US
Steve Yates - Scotland PA, US
Stanley Simpson - San Antonio TX, US
International Classification:
B60G009/02
US Classification:
280/006153, 280/124112
Abstract:
A stabilization and leveling system for an industrial vehicle of a type comprising a frame and at least one axle which is pivotally connected to the frame. The system comprises a linear actuator pivotally connected between the frame and the axle. The linear actuator includes a lock mechanism and a lock override system. The linear actuator is freely extendable and retractable when the lock mechanism is in a non-actuated condition, such that the axle is freely tiltable relative to the frame, and locked against free extension and retraction upon actuation of the lock mechanism, thereby preventing free movement of the linear actuator and resultant free tilting of the axle relative to the frame. The lock override system is actuable to override the lock mechanism to extend or retract the linear actuator to permit controlled tilt of the axle when it is locked.

Method And Apparatus For Maintaining A Load Raising Linkage In A Rasied Position

US Patent:
4947705, Aug 14, 1990
Filed:
Mar 5, 1990
Appl. No.:
7/488502
Inventors:
Steve K. Yates - Scotland PA
Tracy M. Darland - Cheshire, GB2
Assignee:
Ingersoll-Rand Company - Woodcliff Lake NJ
International Classification:
B66C 2388
US Classification:
74529
Abstract:
A device for maintianing a load raising linkage in a raised position. A power member is provided for raising and lowering the linkage. A locking member is pivotally connected to the load raising linkage. The locking member is movable between a lock position and an unlock position. An anchor is connected to the linkage. A releasable member is carried by the locking member. The releasable member engages the anchor and maintains the locking member in the unlock position. Upon pivoting the locking member to the lock position, the releasable member can also engage the power member and maintain the locking member in the lock position.

Soil Compactor And Traction Control System Thereon

US Patent:
5915492, Jun 29, 1999
Filed:
May 26, 1998
Appl. No.:
9/085315
Inventors:
Steve K. Yates - Scotland PA
Edward D. Magalski - York PA
Keith Williams - Minnetonka MN
Assignee:
Ingersoll-Rand Company - Woodcliff Lake NJ
International Classification:
B60K 2816
US Classification:
180197
Abstract:
An earth compactor is propelled by a hydraulic circuit that includes a first hydraulic motor to drive a drum member and a second hydraulic motor to drive a tractor member mounted on tires, with a traction control system that includes a motor speed sensing device on each hydraulic motor. The speed sensing devices transmit electrical signals to a microcontroller, which compares the speeds and varies the speed of the tires or drum to maintain a preselected ratio between the two, thereby maintaining traction of both members. The compactor includes a ground slope sensing device which generates electrical signals and transmits the signals to the microcontroller such that, whenever the tires become elevated above the drum, the microcontroller lowers the speed of the tires and the drum to prevent tire hop.
