Abstract
Abstract Apparatus is provided for introducing a force to be measured from a force transfer element into the free end of a bending rod held rigidly at one end. The apparatus comprises means, e.g. two knife-edges for guiding the force transfer element in the direction of the bending rod, a first rounded contact surface on the force transfer element, a second rounded contact surface on the bending rod, a coupling element having first and second flat parallel spaced substantially horizontal surfaces and interposed between the first and second contact points with its first surface bearing against the first contact surface and its second surface bearing against the second contact surface, and means for holding the coupling element substantially centrally and resiliently relative to the first and second contact surfaces.

Claim 2
Dependent Claim
122 words
Apparatus for introducing a force to be measured from a force transfer element into the free end of a bending rod held rigidly at one end, said apparatus comprising means for guiding the force transfer element in the direction of said bending rod, a first rounded contact surface on the force transfer element, a second rounded contact surface on the bending rod, a coupling element having first and second flat parallel spaced substantially horizontal surfaces and interposed between the first and second contact surfaces with its first surface bearing against the first contact surface and its second surface bearing against the second surface, and means for holding the coupling element substantially centrally and resiliently relative to the first and second contact surfaces.
Claim 3
Dependent Claim
27 words
Apparatus as claimed in claim 1, wherein the rounded contact surfaces are formed by balls supported by bushes carried by the transfer element and bending rod respectively.
Claim 4
Dependent Claim
12 words
Apparatus as claimed in claim 2, wherein each bush is right cylindrical.
Claim 5
Dependent Claim
17 words
Apparatus as claimed in claim 1, wherein the coupling element is a rod with plane-parallel end faces.
Claim 6
Dependent Claim
12 words
Apparatus as claimed in claim 4, wherein the rod is right cylindrical.
Claim 7
Dependent Claim
25 words
Apparatus as claimed in claim 1, wherein the coupling element is held only on the transfer element by means of a collar of resilient material.
Claim 8
Dependent Claim
25 words
Apparatus as claimed in claim 1, wherein the coupling element is held only on the bending rod by means of a collar of resilient material.
Claim 9
Dependent Claim
29 words
Apparatus as claimed in claim 1, wherein the coupling element is held on both the transfer lever and the bending rod by means of a collar of resilient material.
