Abstract
Abstract An improved weight sensing apparatus wherein the output signal of a transducer and, therefore, the reading on a weight meter is rendered accurate regardless of the location of the load. The invention includes providing a set of stabilizing flexures forming a parallelogram with the flexures interconnecting a fixed base and a movable outrider which is adapted to receive the load. A beam balance lever has one end secured to the outrider, and the other end is mass balanced and is built into the parallelogram so that the reduced section of the transducer which interconnects the beam and the fixed base is in alignment with either the top or bottom flexures of the parallelogram. The load end of the lever is secured to the outrider by means of a vertical flexure, loaded in tension, so as to carry the force created by the load into the lever from the outrider; and, in this fashion, avoids rendering the device sensitive to the precise placement of the load on the outrider. Also disclosed is an improved hydraulic damper with the well of the damper attached to the outrider so that it moves with the outrider in response to the force created by the load while the plunger is fixed against inadvertent movement and is externally adjustable to control the damping factor.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A weight sensing assembly comprising: (A) a fixed vertically extending support; (B) a movable vertically extending outrider; (C) a plurality of horizontally disposed stabilizing flexure members (1) interconnecting said support and said outrider, and (2) forming a parallelogram therewith; (D) an elongate lever having first and second ends; (E) said first end of said lever being secured to said outrider for movement therewith; (F) a counter balance secured to said second end of said lever (G) a transducer interconnecting said fixed support with said lever intermediate said first and second ends and disposed in a plane parallel to the plane of said fixed support and adjacent the point of interconnection of said stabilizing flexures and said fixed support; and (H) means connected to said transducer for measuring the movement of said outrider.
Claim 2
Dependent Claim
132 words
A weight sensing assembly comprising: (A) a fixed vertically extending support; (B) a movable vertically extending outrider; (C) a plurality of horizontally disposed stabilizing flexure members (1) interconnecting said support and said outrider, and (2) forming a parallelogram therewith; (D) an elongate lever having first and second ends; (E) said first end of said lever being secured to said outrider for movement therewith; (F) a counter balance secured to said second end of said lever (G) a transducer interconnecting said fixed support with said lever intermediate said first and second ends and disposed in a plane parallel to the plane of said fixed support and adjacent the point of interconnection of said stabilizing flexures and said fixed support; and (H) means connected to said transducer for measuring the movement of said outrider.
Claim 3
Dependent Claim
33 words
