Abstract
Abstract The invention covers an improved rail scale having a live rail and at least two weight measuring means adapted to be mounted and secured onto the fixed railsupport system. The improvement comprises the use of a single unitary U-shaped rail hanger having a length that is substantially co-extensive with the length of the live rail. Another improvement comprises the use of load cells as the weight measuring means wherein the load cells are mounted with their cylindrical axis at right angles to the lateral axis of the live rail.

Claim 1
Independent Claim
87 words
An improved rail scale having a live rail and at least two weight measuring means adapted to be fixedly connected to a rail support system, said improvement comprising a single unitary U-shaped rail hanger having a length that is substantially co-extensive with the length of the live rail, said U-shaped rail hanger having a first leg adapted for connection to the live rail, a second leg adapted for connection to the weight measuring means, and a vertical member connecting said legs and parallel to the live rail.
Claim 2
Dependent Claim
87 words
An improved rail scale having a live rail and at least two weight measuring means adapted to be fixedly connected to a rail support system, said improvement comprising a single unitary U-shaped rail hanger having a length that is substantially co-extensive with the length of the live rail, said U-shaped rail hanger having a first leg adapted for connection to the live rail, a second leg adapted for connection to the weight measuring means, and a vertical member connecting said legs and parallel to the live rail.
Claim 3
Dependent Claim
31 words
An improved rail scale as set forth in claim 1 wherein said legs are substantially parallel to each other and are disposed to said vertical member at approximate right angles thereto.
Claim 4
Dependent Claim
33 words
An improved rail scale as set forth in claim 1 wherein said weight measuring means comprise load cells having their cylindrical axes at right angles to the lateral axis of the live rail.
Claim 5
Dependent Claim
42 words
An improved rail scale as set forth in claim 1 wherein said scale is enclosed in a rectangular box which provides a visual indication of when the live rail is loaded with a weight by the relative downward movement of said box.
