A platform weighing scale and loading adapter therefor

Claim 2

In a weighing scale having a platform and a balance beam or other means of weight indication a top surface on said platform extending lengthwise beyond the length of said platform in a direction away from said balance beam, tracks on said top surface, said tracks bracketing opposite sides of said platform and extending in the direction of the length thereof to guide the wheels of a vehicle from the entrance thereof for movement toward said balance beam, each of said tracks depending from said top surface a distance spaced from the surface on which the scale is supported, and means at the entrance of each track to define a ramp inclined from the supporting surface to its respective track.

Claim 3

In a weighing scale as in claim 1, stop means at one end of each of said tracks opposite said ramp means to stop the movement of a vehicle along said tracks, and said ramp means being pivotable on and relative to their respective tracks from an inclined position to afford entry to and egress from said tracks and a substantially upward position to stop egress from said tracks.

Claim 4

In a weighing scale as in claim 2, means on said top surface conforming to preselected portions of the configuration of said platform to prevent relative horizontal movement between said top surface and platform.

Claim 5

In a weighing scale as in claim 1, a counterbalance on said balance beam including means to releasably secure the same to said balance beam to counterbalance the weight of said top surface, tracks and ramp means on said platform.

Claim 6

In a weighing scale as in claim 4, and a handrail on and extending upward for a selected height of said scale adjacent said balance beam and between said top surface and balance beam.

Claim 7

A removable adapter for a weighing scale comprising a substantially planar top surface of a size and shape for placement astride the platform of a weighing scale, a pair of tracks one each depending from said top surface along opposite sides thereof and each track having a horizontal riding surface disposed along a substantially horizontal plane lower than said top surface, a ramp pivotally mounted on each of said tracks for movement to a position inclined downward with respect to its track and to a position inclined upward with respect to its track, and means on said top surface to position the same on a platform of a weighing scale to prevent relative horizontal movement therebetween and permit relative vertical movement therebetween.

Claim 8

A removable adapter for a weighing scale comprising a substantially planar top surface of a size and shape for placement astride the platform of a weighing scale, a pair of tracks one each depending from said top surface along opposite sides thereof and each track having a horizontal riding surface disposed along a substantially horizontal plane lower than said top surface, a ramp pivotally mounted on each of said tracks for movement to a position inclined downward with respect to its track and to a position inclined upward with respect to its track, and means on said top surface to position the same on a platform of a weighing scale to prevent relative horizontal movement therebetween and permit relative vertical movement therebetween.

Claim 9

A removable adapter as in claim 6, a handrail connected to said top surface and extending upward therefrom to a selected height.

Claim 10

A removable adapter as in claim 7, said handrail being an inverted substantially U-shape defining an upstanding abutment at one end of said top surface opposite that of said ramps.

Claim 11

A removable adapter as in claim 8, stop means at the ends of each of said tracks opposite said ramps to terminate the extent of each said ramp.
