Abstract: A universal vise jaw cover comprising an elongated flat panel of resilient material, such as leather, of predetermined length, width, and thickness with a system of self-attachment applied to the backside of the vise jaw cover. The system or systems of self-attachment can be of differing forms. One form is when an adhesive material is applied to the backside of the vise jaw cover and the exposed adhesive material is then applied to the front side of the vise jaw. Another form is when a flexible magnetic material is glued with epoxy or adhesive material to the backside of the vise jaw cover and when the vise jaw cover is applied to a vise jaw of ferrous material, the magnetic material will hold the vise jaw cover in place while the vise is not in use.

Abstract: A shoe or clamp assembly for securing a buffer stop or bumping post to railroad track with a predetermined magnitude of retardation against sliding movement of the buffer stop when the same is engaged by a moving railcar to be stopped. The shoe assembly which clamps against opposite sides of a buffer stop wall, and also clamps against opposite sides of a rail, is secured by at least one bolt and nut and also a spring stack so that a torque wrench is not required in order to effect such securement.

Abstract: A rail length and rail joint is described which avoids the use of bolts, the rail length comprising basically a fastening element secured at each rail end to be joined, the element being provided with a through bore extending parallel to the longitudinal axis of the associated rail length and a projection located in a position in which it intersects the bore and being radially displaceable to a location in which it lies clear of the bore. The rail length may be provided at each end with such a fastening element, one constituting a male element and the other a female element, the rail joint incorporating abutting male and female elements and a necked connecting pin.
