Patent number: 9422674Abstract: An improved in-track welder eliminates conduction path force members and employs separate bridging current path conductors for DC welding of rail ends. The enhancement allows for an increased closure distance, thus improving cold-weather operations. An increased allowable distance between conduction contacts allows for the incorporation of an internal shear member for more efficient finishing of welds. The force members may be optimized for strength rather than electrical properties, and are comprised of relatively small diameter alloy steel rods.Type: GrantFiled: July 15, 2008Date of Patent: August 23, 2016Assignee: Chemetron-Railway Products, Inc.Inventors: Charles R. Battisti, Gary Barnhart

Patent number: 8658935Abstract: An improved welding head for creating an in-track weld between a first rail segment and a second rail segment includes a controller having computer-readable instructions read by the controller. The computer-readable instructions include instructions for compensating for rail jerk during in-track welding. The welding head includes a closing force actuator, such as a hydraulic cylinder, for moving the rail segments toward one another. A pressure transducer is monitored during welding to determine a closing force. An impending jerk of the rail movement is detected if an abnormal closing force change is observed, and in response the flow of hydraulic fluid into or out of the hydraulic cylinder is restricted to prevent or minimize the jerk. In addition, when an impending jerk is detected the weld current may be temporarily increased to burn or prevent the formation of short circuit paths between the rails.Type: GrantFiled: November 10, 2009Date of Patent: February 25, 2014Assignee: Chemetron-Railway Products, Inc.Inventors: Charles R.

Publication number: 20130284705Abstract: An improved method for executing a flash butt weld to join first and second rail segments includes applying a voltage to the first rail segment and the second rail segment to establish a voltage difference between the first and second rail segments. The rail end faces are brought into contact, resulting in an electrical current between the first rail end face and the second rail end face, resistively heating material at the interface. As material burns off at the interface, the power consumed at the rail end interface as a function of rail displacement is periodically sampled. If the comparison indicates that the power per unit of rail displacement is not increasing from sample to sample, the burn-off process is terminated. In a further aspect, if the power per unit of rail displacement exceeds a predetermined threshold, the burn-off process is terminated.Type: ApplicationFiled: June 24, 2013Publication date: October 31, 2013Inventors: Charles R. Battisti, Gary Barnhart

Patent number: 6481540Abstract: A brake controlling mechanism for a cart having a conventional handle mounting bracket defining a handle mounting axis. A core is shiftably coupled to the handle mounting bracket and rotatable about the handle mounting axis. An elongated handle is coupled to the core offset relative to the handle mounting axis.Type: GrantFiled: July 12, 2001Date of Patent: November 19, 2002Inventors: Herman F. Nolting, Jr., Robert E. Doughty, Gary A. Barnhart

Patent number: 6123343Abstract: A braking mechanism (20) for a grocery cart or the like is disclosed as including a braking assembly (50) that is selectively shiftable between braking and non-braking positions and a handle assembly (52) interconnected to the braking assembly (50) for effecting the selective brake assembly shifting. The braking assembly (50) includes a chock element (60) shiftably mounted adjacent at least one of the cart wheels (26) and configured for wedging engagement between the periphery (65) of the wheel (26) and the support surface (66) to impede forward movement of the cart (22). The handle assembly (52) includes a tubular body (112) for fitting over the existing cart handle (28) and a pair of rotor cup assemblies (118, 120) supporting the tubular body (112) on the cart body (24, for selective pivotal movement substantially about the longitudinal axis of the cart handle (28).Type: GrantFiled: December 9, 1997Date of Patent: September 26, 2000Inventors: Herman F.

Patent number: 5988889Abstract: A motor fan bracket is molded of a fiber reinforced thermoset polyester. The motor/fan bracket has an annular frame and an annular bearing housing concentric with the frame and supported by inwardly extending arms. The annular bearing housing has a bearing-receiving cavity configured in cross section as an equilateral polygon such that each face of that cavity is tangential to a bearing received therein.Type: GrantFiled: May 7, 1998Date of Patent: November 23, 1999Assignee: Ametek, Inc.Inventors: Gary A.

Patent number: 5569017Abstract: An improved end bracket is provided for a high velocity low pressure blower assembly. The end bracket includes a pair of members, each heat sink having several vanes. The bracket further includes a bearing boss having heat dissipating vanes radiating from it. The heat sink members and vanes serve to dissipate heat from a bearing which is mounted in the bearing boss. The bracket also includes a tangential exhaust horn having a threaded hose coupling. The exhaust horn communicates with a tapered scroll passage which serves to direct air to the exhaust horn. The scroll passage is tapered to allow the high velocity air to expand as it becomes hotter, thereby reducing turbulence at the exhaust.Type: GrantFiled: December 22, 1994Date of Patent: October 29, 1996Assignee: Ametek, Inc.Inventors: Gary A. Barnhart, David P. Gill

Patent number: 4789290Abstract: A machine for orienting and stacking receptacles, such as cups having a base end and a mouth end, which machine includes a receiving area wherein the cups are initially received and are then fed to an upright, angularly disposed conveyor, the cups being received between bars presented by the conveyor. As the cups are moved upwardly by the conveyor, they come into engagement with an angularly disposed orienting roller which spans the width of the conveyor and contacts the cups to shift them into a common, oriented relationship with the mouths all facing in one direction and the bases in another. After orientation, the cups pass over the top of the conveyor and are removed therefrom and carried to a delivery location. The removal of the cups from the conveyor is accomplished by a vacuum which is drawn adjacent the top end of the conveyor.Type: GrantFiled: January 4, 1988Date of Patent: December 6, 1988Assignee: Carson/Burger/Weekly, Inc.Inventors: Gary A.
