Abstract
Abstract A collapsible scale having hydraulic pressure responsive cells in support of an animal weighing platform. Ramp components are detachable from the main portion of the scale as is an instrument stand facilitating the collapsing of the scale for pick-up truck transport to a remote livestock weighing site. Conduit means communicating the cells with a pressure indicator on the instrument stand includes a flexible component allowing detachment and repositioning of the stand without conduit separation. Adjustable pre-loading means for the cells and conduit means permit pressurizing of same prior to start of a weighing operation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
186 words
A collapsible hydraulic scale conveniently transportable to remote locations for the weighing of livestock, said scale comprising, a base of rectangular configuration, ramps attachable to opposite ends of said base, a weighing platform on sAid base, means confining said platform in place on said base, pressure cells intermediate said platform and the base each including a flexible disc component deformable upon preloading of the pressure cells with a fluid charge, an instrument stand removably attached to one side of said base, conduit means including a flexible hose segment located adjacent said instrument stand permitting detachment of the stand from the base and horizontal repositioning of the stand during collapsing of the scale for travel without disconnecting said conduit means, pressure indicating means located on said stand for viewing by a scale operator and in fluid communication with said conduit means for indicating fluid pressure resulting from a weighed load on the platform, and pressurizing means located on said stand for pre-loading said pressure cells and said conduit means, said pressurizing means additionally adapted to store a quantity of fluid for replenishment of the scales fluid supply.
Claim 2
Dependent Claim
186 words
A collapsible hydraulic scale conveniently transportable to remote locations for the weighing of livestock, said scale comprising, a base of rectangular configuration, ramps attachable to opposite ends of said base, a weighing platform on sAid base, means confining said platform in place on said base, pressure cells intermediate said platform and the base each including a flexible disc component deformable upon preloading of the pressure cells with a fluid charge, an instrument stand removably attached to one side of said base, conduit means including a flexible hose segment located adjacent said instrument stand permitting detachment of the stand from the base and horizontal repositioning of the stand during collapsing of the scale for travel without disconnecting said conduit means, pressure indicating means located on said stand for viewing by a scale operator and in fluid communication with said conduit means for indicating fluid pressure resulting from a weighed load on the platform, and pressurizing means located on said stand for pre-loading said pressure cells and said conduit means, said pressurizing means additionally adapted to store a quantity of fluid for replenishment of the scales fluid supply.
Claim 3
Dependent Claim
34 words
The scale as claimed in claim 1 wherein said platform confining means includes ramp supporting sockets secured to the base of the scale and extending upwardly therefrom additionally serving to receive insertable ramp components.
Claim 4
Dependent Claim
51 words
The scale as claimed in claim 2 wherein said insertable ramp components comprise swingably mounted connectors carried at the upper ends of said ramps, said connectors upon disengagement from their base carried sockets during collapsing of the scale being upwardly positionable against their respective ramps for purposes of compact ramp stowage.
Claim 5
Dependent Claim
47 words
The scale as claimed in claim 3 wherein said conduit means includes a flexible hose segment located adjacent said instrument stand permitting detachment of the stand from the base and horizontal repositioning of the stand during collapsing of the scale for travel without disconnecting said conduit means.
