Hole bisected four-bolt split flange connector

Claim 1

An improved split flange connector for assembling highpressure fluid couplings on associated hydraulic components comprising: a flat disc-shaped flange of uniform thickness having a central aperture and four attaching bolt holes circumferentially disposed about said aperture in its central portion, said bolt holes located so that diametrically opposite bolt holes have their axes located on one or the other of two intersecting diametric lines passing through the center of said disc-shaped flange, said disc-shaped flange also bisected along one of said diametric lines dividing said disc-shaped flange into two identical arcuate sectors, each of said sectors having a central bolt hole and two half holes at its opposite ends whereby assembly of like sectors will form a flange with four bolt holes, said diametric lines being within 40* of being perpendicular and located so said central bolt holes are asymmetric to the other bolt holes, a counter bore milled in said disc-shaped flange forming in each sector a central internal stepped arcuate wall for cooperating with a bearing surface of a head of a high-pressure fluid coupling to be secured, and four attaching bolts having a head portion larger than its associated bolt hole for attaching each of said sectors with three of the four bolts when assembled on a component structure to which said high-pressure coupling is to be secured, said attaching bolts sized closely to said bolt holeS to limit motion of said sectors when assembled on said component structure.
