Abstract
Abstract An externally-mounted strain-gage transducer for sensing aircraft weight components in response to load-induced deformations of a support such as an axle, truck beam, or the like, is of an elongated form with end lugs designed for bolting to cooperating horizontally-spaced lugs integral with the support, the transducer end lugs each being provided with an adjustably-deformable hole-and-slot type symmetrical flexural connection by which the transducer ends may be raised or lowered wholly in the desired vertical direction to offset effects such as those of otherwise-unavoidable installation zero shift.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
On-board vehicle weight transducer apparatus responsive to elastic deformation of a support such as a truck beam or axle for the vehicle, comprising an elongated transducer including a relatively deformable strain-gaged element and relatively rigid connectors at the ends of said element, means for securing said connectors with such a support at different longitudinally-spaced positions therealong, at least one of sadi connectors including an integral bifurcated portion the branches of which are separated from one another and means for adjusting the spacing between said branches, the junction of said bifurcated portion and one of the branches of said portion being fixed in relation to different ones of the support and an end of said element, whereby adjustment of said spacing between said branches results in displacement of said end and the support in substantially one direction.
Claim 2
Dependent Claim
136 words
On-board vehicle weight transducer apparatus responsive to elastic deformation of a support such as a truck beam or axle for the vehicle, comprising an elongated transducer including a relatively deformable strain-gaged element and relatively rigid connectors at the ends of said element, means for securing said connectors with such a support at different longitudinally-spaced positions therealong, at least one of sadi connectors including an integral bifurcated portion the branches of which are separated from one another and means for adjusting the spacing between said branches, the junction of said bifurcated portion and one of the branches of said portion being fixed in relation to different ones of the support and an end of said element, whereby adjustment of said spacing between said branches results in displacement of said end and the support in substantially one direction.
Claim 3
Dependent Claim
60 words
On-board vehicle weight transducer apparatus as set forth in claim 1 wherein said bifurcated portion is formed by a slot and an enlarged hole at the closed end of the slot, material between the hole and nearby external surfaces of said connector being of reduced cross-section and thereby forming two relatively deformable flexures one on each side of the slot.
Claim 4
Dependent Claim
47 words
On-board vehicle weight transducer apparatus as set forth in claim 1 wherein siad junction is fixed in relation to an end of said element, and wherein said securing means mounts one of said branches in fixed relation to the support at one of the longitudinally-spaced positions therealong.
Claim 5
Dependent Claim
63 words
On-board vehicle weight transducer apparatus as set forth in claim 3 wherein said junction is integrally united with said end of said element, wherein said means for adjusting the spacing between said branches comprises a nut and bolt for adjustably drawing said branches closer together, and wherein said bolt further mounts said one of said branches in said fixed relation to the support.
Claim 6
Dependent Claim
46 words
On-board vehicle weight transducer apparatus as set forth in claim 1 wherein said one of said branches is fixed in relation to an end of said element, and wherein said securing means mounts said junction in fixed relation to the support at one of said positions.
Claim 7
Dependent Claim
69 words
On-board vehicle weight transducer apparatus as set forth in claim 5 wherein said one of said branches in integrally united with said end of said element, and wherein said means for adjusting said spacing between said branches comprises a set screw threadedly engaged with one of said branches and having an end abutting the other of said branches, whereby adjustment of said set screw adjustably spreads said branches apart.
Claim 8
Dependent Claim
78 words
On-board vehicle weight transducer apparatus as set forth in claim 1 for use with such a support which includes a pair of lugs externally thereof and integrally therewith, one at each of the spaced positions and in substantially horizontal alignment, and wherein said securing means secures said connectors to the external lugs of the support, the one of said junction and branches which is fixed in relation to the said end of said element being integrally united therewith.
Claim 9
Dependent Claim
51 words
On-board vehicle weight transducer apparatus as set forth in claim 7 for use with such a support in which the lugs are substantially aligned with a horizontal plane including the neutral axis of the support, and wherein both of said connectors include an integral bifurcated portion and are substantially the same.
