Abstract
A wheel chock assembly for chocking the wheel of a railroad car including a chock having at least one inclined ramp surface, a bottom surface, and opposite side surfaces. Each one of the opposite side surfaces of the chock contains a bore. A positioner presents an elongate arm with a retriever at one end thereof. The retriever has a projection which is receivable within a selected one of the bores in the opposite side surfaces. When the projection engages a selected one of the bores, the positioner can carry the chock for the selective positioning of the chock.
Claims10
A wheel chock assembly for chocking the wheel of a railroad car by an operator wherein the railroad car rides on a rail, the assembly comprising:
- a discrete chock having a pair of inclined ramp surfaces that intersect at an apex, the chock having a bottom surface, and opposite side surfaces, each one of the opposite side surfaces of the chock containing a bore, and each one of the bores is inclined upwardly toward the apex;
- and
- a discrete positioner comprising an elongate arm having a retriever at one end thereof, the retriever having a projection which is receivable within the bore in a selected one of the opposite side surfaces, when the projection engages the bore in the selected one of the side surfaces the positioner projects away from the selected side surface so that the positioner can carry the chock for the selective positioning of the chock in such a fashion that the elongate arm is generally perpendicular to the rail on which the railroad car rides.
A wheel chock assembly for the chocking by an operator of the wheel of a railroad car which rides on a rail, the assembly comprising:
- a chock having at least one inclined ramp surface, the chock having a bottom surface, and opposite side surfaces, each one of the opposite side surfaces of the chock containing a bore, each one of the bores inclining upwardly away from the bottom surface;
- and
- a positioner comprising an elongate arm having a retriever at one end thereof, the retriever having a projection which is receivable within the bore of a selected one of the opposite side surfaces, when the projection engages the bore in the selected side surface the elongate arm of the positioner projects away from the selected side surface so that during the positioning of the chock on the rail the elongate arm extends away from the rail, and wherein when the projection engages the bore in the selected side surface the elongate arm of the positioner projects away from the selected side surface so as to be generally perpendicular to the selected side surface.
