Abstract
A guide-rail assembly has an anchor plate having an upstanding flange with a transversely directed face and formed below the face with at least one transversely throughgoing hole and a guide rail above the hole and having a transversely directed outer face bearing transversely on the flange face and an inner face directed transversely oppositely. A J-bolt has a bearing face directed transversely toward and bearing on the guide-rail inner face and a shank extending through the hole below the guide rail. A nut threaded on the shank and engaging an outer surface of the plate presses the J-bolt bearing face against the guide-rail inner face and clamps the guide rail against the anchor-plate face.
Claims15
A guide-rail assembly comprising:
- an anchor plate having an upstanding flange with a transversely directed face and formed below the face with at least one transversely throughgoing hole;
- a guide rail above the hole and having a transversely directed outer face bearing transversely on the flange face and an inner face directed transversely oppositely;
- a J-bolt having
- a bearing face directed transversely toward and bearing on the guide-rail inner face and
- a shank extending through the hole below the guide rail;
- and
- a nut threaded on the shank, engaging an outer surface of the plate, pressing the J-bolt bearing face against the guide-rail inner face, and clamping the guide rail against the anchor-plate face, the hole and shank being centered on a common axis, the plate and J-bolt being formed with complementary generally planar surfaces extending generally parallel to the axis and engaging one another, whereby rotation of the J-bolt about the axis is inhibited by engagement of the planar surfaces, the plate planar surface being formed in the hole and the J-bolt planar surface being formed on the shank, the plate planar surface being directed downward and the J-bolt planar surface being directed upward.
The guide-rail assembly defined in claim wherein the J-bolt bearing face carries a compressible bumper.
A guide-rail assembly comprising:

- a guide rail above the hole and having a transversely directed outer face bearing transversely on the flange face and an inner face directed transversely oppositely;
- a J-bolt having
- a bearing face directed transversely toward and bearing on the guide-rail inner face and
- a shank extending through the hole below the guide rail;
- and
- a nut threaded on the shank, engaging an outer surface of the plate, pressing the J-bolt bearing face against the guide-rail inner face, the anchor-plate face carrying a compressible bumper, the anchor-plate bumper being recessed in the anchor-plate face.
