Abstract: An improved design that would allow one workman to easily elevate a heavy concrete tie to the base of the rail and hold it in position while tie is connected to the rail with retainer clips. Improvements are made in the handle design that allow the workman to remain in a more upright position at the time the tie comes in contact with the rail. Also added is a safety grip ring near the upper end of the handle. Design improvements are also made at the foot end of the handle unit. At this point the improved tool design will allow more leverage to be applyed to the tie and a varity of hook devises to be used on lower end of tool, depending on what type of concrete tie is to be used.

Abstract: A device for adjusting the butt-ends of two rails to be connected has a fixed frame for enclosing one of the two rails and two integral bars, parallel to the rails, and extending from the fixed frame toward the other rail. Two movable frames are slidable over a limited portion of the parallel bars in the vicinity of the other rail and can be selectively secured to the other rail so that only one of these two frames is slidably movable. Jacks are provided to effect relative movement between the two movable frames. Actuation of the jacks effects movement of the two movable frames relative to each other and, depending upon which of these frames is secured to the parallel bars, the gap between the two butt-ends will be either increased or decreased.

Abstract: A method and a system for correcting the misalignment of a railroad track is provided which corrects the track by the steps of applying a force laterally of the track to move it in the direction of its correct position, sensing the track position relative to a datum, automatically reducing the force in response to the sensing step, permitting the track to react to the reduction of the force and automatically rapidly repeating the force application, sensing, and reduction steps to set up a vibratory cycle of force application until the desired track condition has been achieved. The system provides a valve which has a rail position feeler in the hydraulic connection between pump and jack, which feeler upon sensing the rail operates to close the valve to terminate a jacking action. Pressure sensitive switch is provided in the hydraulic connections between the valve and the pump that operates to exhaust the jack when a pre-determined pressure has been built up in the connections between the pump and the valve.
