Abstract
A replacement hasp for a railroad sliding door lock mechanism, a kit for making the hasp, and method for making the replacement using the kit are disclosed in two embodiments. The kit includes a member which partially defines an eye, sized to fit loosely about the existing hasp-retaining link on the car, and an eye-completion member arrayed to mate with the first member and form a replacement hasp when affixed thereto, as by welding with shear welds. In the first embodiment, the first member is generally U-shaped and the second member includes a tongue portion which mates between the ends of the partial-eye-defining member such that the two can be 'telescoped' together to form a replacement hasp of different lengths to accommodate changes in the door or door jamb of the railroad car. The two main members include furrows extending along the parting lines between them so as to aid in welding the main members together and to form a stronger affixture than is possible under the prior commercial practice. The second embodiment is similar to the first but includes a keyway formed through the members and a key which may be inserted when they are mated together in their usual intended position to affix the members together.
