Abstract
A pipe bell-end ring flare device for use with a mandrel to form bell ends with a flared outer edge in plastic pipe sections either as part of the pipe manufacturing process or subsequent to the manufacturing process. The flared edge creating a wider bell end opening to make it easier to insert a non-bell end of another pipe into the flared bell end.
Claims23
A device comprising:
- an upper section including an inner circumferential surface being coaxially aligned with and parallel and opposite to an outer circumferential surface, a top surface orthogonal to both of the inner circumferential surface and the outer circumferential surface and connected at an inner end of the top surface to a top edge of the inner circumferential surface and connected at an outer end of the top surface to a top edge of the outer circumferential surface, the outer circumferential surface depending downwardly away from the top surface and terminating at a bottom edge of the outer circumferential surface, the bottom edge of the outer circumferential surface being connected to an outer bottom edge of a bottom surface of the outer circumferential surface, the bottom surface of the outer circumferential surface extending orthogonally and radially inwardly toward the inner circumferential surface, a plurality of equidistantly spaced recessed fastener openings formed around and through the upper section with a recessed fastener head receiving opening portion of each recessed fastener opening being formed in the outer circumferential surface and a coaxially aligned fastener body receiving opening portion of each recessed fastener opening being formed in the inner circumferential surface;
- and
- a lower section including a bottom portion of the inner circumferential surface forming a continuous and axially aligned extension of the inner circumferential surface of the upper section, the lower section terminating with a bottom edge of the inner circumferential surface, the bottom edge of the inner circumferential surface being connected to a bottom edge of an upwardly and outwardly extending angled outer circumferential lower surface, a top edge of the upwardly and outwardly extending angled outer circumferential lower surface connected to an inner edge of the bottom surface of the upper section.
An apparatus comprising:
- a pipe bell-end ring flare device including:
- an upper section including an inner circumferential surface being coaxially aligned with and parallel and opposite to an outer circumferential surface, a top surface orthogonal to each of the inner circumferential surface and the outer circumferential surface and connected at an inner end of the top surface to a top edge of the inner circumferential surface and connected at an outer end of the top surface to a top edge of the outer circumferential surface, the outer circumferential surface depending downwardly away from the top surface and terminating at a bottom edge, the bottom edge of the outer circumferential surface being connected to an outer bottom edge of a bottom surface, the bottom surface extending orthogonally and radially inwardly toward the inner circumferential surface, a plurality of equidistantly spaced recessed fastener openings formed around and through the upper section, each of the plurality of equidistantly spaced recessed fastener openings including a recessed fastener head receiving opening portion of each recessed fastener opening being formed in the outer circumferential surface and connected to a coaxially aligned fastener body receiving opening portion formed in the inner circumferential surface;
- and
- a lower section including a bottom portion of the inner circumferential surface forming a continuous and coaxially aligned extension of the inner circumferential surface of the upper section, the lower section terminating with a bottom edge of the inner circumferential surface, the bottom edge of the inner circumferential surface being connected to a bottom edge of an upwardly and outwardly extending angled outer circumferential lower surface, a top edge of the upwardly and outwardly extending angled outer circumferential lower surface connected to an inner edge of the bottom surface of the upper section;
- and
- a mandrel including a proximal end having a first surface with a first circumference and a plurality of separate, recessed, and threaded openings formed in the first surface of the proximal end and to which the pipe bell-end ring flare device is fixedly and removably attached, a distal end including an end portion having a second surface with a second circumference, and a body portion having a body surface with the first circumference and connected at a first end to the proximal end and at a second end to the distal end.
