Abstract
Abstract A fluid transfer piping comprising a swinging rigid pipe section fulcrumed to and connected by means of a swivel joint onto a stand pipe, a supplementary pipe section connected by a swivel joint to the free end of said swinging pipe section, a counterpoise pivotably supported eccentrically on a cantilever arm extending from said stand pipe, and connecting members connecting said counterpoise and said swinging pipe sections so that by swinging the swiveling pipe sections with respect to the stand pipe and to one another, the counterpoise is rotated so as to always substantially balance the varying momentum of the swiveling rigid pipe sections.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
223 words
A device for transferring fluid from a relatively stationary stand pipe to a remote intake pipe which is unstable and subject to movement, said device comprising a main pipe section pivotally connected with the stand pipe and communicating therewith in all adjusted positions and projecting beyond one side of the stand pipe, a rigid arm extension on the main pipe section projecting beyond the other side of the stand pipe, an auxiliary pipe section pivoted to the main pipe section near the free end of the latter and communicating with the main pipe section in all adjusted position, said auxiliary pipe section projecting beyond one side of the pivot thereof, a rigid arm extension on the auxiliary pipe section projecting beyond the other side of the pivot thereof, a counterpoise weight pivoted eccentrically to the rigid arm extension of the main pipe section, and a connecting rod extending between the counterpoise weight and the rigid arm extension of the auxiliary pipe section and being pivoted to the rigid arm extension of the auxiliary pipe section and also being pivotally connected to the counterpoise weight at a point substantially diametrically opposite the pivotal connection of the weight with the rigid arm extension of the main pipe section, to thereby form a parallelogram linkage with the counterpoise weight itself constituting one arm of the linkage.
