Abstract:
1. A compression generator, including the combination of: a first pipe member having at least one threaded aperture and an internal cavity accessible from said at least one threaded aperture to install and displace a compression shoe in said internal cavity into frictional contact with a second pipe member in a confronting relation to said at least one threaded aperture; at least one externally threaded carrier affixed by said at least one threaded aperture for retained support by said first pipe member; a plurality of jackbolts each received in one of a plurality of threaded holes at spaced-apart locations about an outer peripheral part of said carrier for extending from said carrier into confronting engagement with said compression shoe residing in said internal cavity and for generating a pushing force against said second pipe member for forming a mechanical connection of said first pipe member with said second pipe member by torque applied to said jackbolts for said connecting said first pipe member to said second pipe member, and a spindle extending from said compression shoe and through a bore in said externally threaded carrier, and a nut on said spindle to limit linear movement of said compression shoe, said nut being dimensioned to seat in a counter bore in said externally threaded carrier to provide guided movement of said spindle throughout a desired range in said internal cavity of said first pipe member.
