Abstract
Abstract A substantially flat, resilient plate positioned over a treadle scale with its lower surface overlying and engaging the upper load-receiving platform of the scale is secured along opposed longitudinal end surfaces of the plate to the framework in which the treadle scale is supported for transmitting loading forces in the normal loading direction only to the scale platform, while simultaneously preventing the application to the platform of adverse side loads which might damage the scale.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
In combination, a treadle scale mounted within a framework, said scale having a substantially flat and rectangular upper load-receiving platform; a protection structure for preventing said scale from being damaged by side loading comprising at least one substantially flat and rectangular resilient plate having a lower surface overlying and engaging said flat upper loadreceiving platform of said scale and an upper surface adapted to receive load applied thereto by tires of vehicles passing thereacross in a travel direction, said structure having opposed longitudinal edges substantially transverse to said travel direction and overlying said framework; and means securing said edges of said structure to said framework, the other edges of said structure being substantially coextensive with said platform and being spaced from said framework to promote deflection of said other edges with said platform.
Claim 2
Dependent Claim
133 words
In combination, a treadle scale mounted within a framework, said scale having a substantially flat and rectangular upper load-receiving platform; a protection structure for preventing said scale from being damaged by side loading comprising at least one substantially flat and rectangular resilient plate having a lower surface overlying and engaging said flat upper loadreceiving platform of said scale and an upper surface adapted to receive load applied thereto by tires of vehicles passing thereacross in a travel direction, said structure having opposed longitudinal edges substantially transverse to said travel direction and overlying said framework; and means securing said edges of said structure to said framework, the other edges of said structure being substantially coextensive with said platform and being spaced from said framework to promote deflection of said other edges with said platform.
Claim 3
Dependent Claim
81 words
The combination of claim 1, wherein said protective structure comprises at least two substantially flat resilient plates mounted oNe upon the other in substantially coextensive relationship, said plates being of substantially the same thickness, the lower surface of the bottom plate overlying and engaging said upper load-receiving platform and the upper surface of the top plate receiving said load applied thereto by tires of vehicles, and wherein said means securing said edges secures said edges of said plates to said framework.
Claim 4
Dependent Claim
52 words
The combination of claim 1, wherein said means securing said edges comprises means fastening each of said edges of said structure to said framework at points lying outside the peripheral limits of said load-receiving platform underlying said structure, and wherein said structure has a thickness substantially between one-sixteenth inch and one-eighth inch.
