Abstract

An improved saddle tee for branching a conduit from a main line is disclosed. The saddle tee includes a base unit that defines an opening for receiving a tap and interlocking jaws for securing the base unit to a main line. The tap may include a shaped portion for receiving a tool interface to rotate the tap to drive the tap into the main line. The tool interface could be secured to a power tool to enable rapid driving of the saddle tee into the main line. The saddle tee may also include offset arcuate interlocking jaws to enable the jaws to interlock around the main line with ease. Optional interface surfaces on the tap and base unit enable the tap and base unit to interlock to limit rotation of the tap relative to the base unit when the tap is fully inserted into the base unit.

Claims

1. A saddle tee for use in branching a conduit from a main line using a tool interface, the saddle tee comprising:

a base unit defining an opening for receiving a tap, said base unit comprising interlocking jaws for securing the base unit to the main line, said base unit further comprising;

a body;

a first arcuate interlocking jaw comprising a first contact end, a first contact surface proximate the first end, a first interlocking end, and a first pivot disposed between the first contact end and the first interlocking end;

a second arcuate interlocking jaw comprising a second contact end, a second contact surface proximate the second contact end, a second interlocking end, and a second pivot disposed between the second contact end and the second interlocking end; and

in an open state, the first and second arcuate interlocking jaws defining a receiving cavity for receiving the main line, the first contact surface being positioned more remote from the body of the base unit than the second contact surface so that positioning the main line within the receiving cavity causes the first arcuate interlocking jaw to rotate and position about the main line before the second arcuate interlocking moves into position about the main line for interlocking engagement with the first arcuate interlocking jaw; and

a tap defining a passageway, the tap comprising;

a tapered end having an aperture in fluid communication with the passageway;

a fitting opposite the tapered end; and

a shaped portion for receiving the tool interface for rotating the tap to drive the tap into penetrating engagement with the main line, the shaped portion being separate and distinct from any wing that may be present on the tap.

2. The saddle tee of claim 1, wherein the tap further comprises at least one wing.

3. The saddle tee of claim 1, wherein the shaped portion comprises a throat defining a portion of the passageway.

4. The saddle tee of claim 1, wherein the tap comprises a first end generally opposite the tapered end, the shaped portion comprising a shaped protrusion on the first end adapted to be positioned within the tool interface.

5. The saddle tee of claim 4, wherein the first and second arcuate jaws are shaped to deform the main line into a generally elliptical cross-sectional shape when the first and second arcuate jaws are positioned about the main line in a locked state.

6. The saddle tee of claim 1, wherein the base unit further comprises a first interface surface having a series of linearly aligned ridges, and wherein the tap further comprises a shoulder having a second interface surface that aligns and seats on the first interface surface to limit rotation of the tap relative to the base unit when the tap is fully inserted into the base unit.

7. The saddle tee of claim 1, wherein the fitting comprises a gripping mechanism that grasps an end of a conduit without annular grooves, annular flanges, or annular beads to secure the end of the conduit within the fitting.

8. The saddle tee of claim 1, wherein the base unit further comprises raised text identifying a size of the main line with which the base is capable of interfacing.

9. The saddle tee of claim 1, wherein the tap further comprises raised text identifying a size of the conduit with which the tap is capable of interfacing, the raised text further comprising a reinforcement rib.

10. A saddle tee for use in branching a conduit from a main line, the saddle tee comprising:

a base unit having a body defining an opening for receiving a tap and further comprising;

a first arcuate interlocking jaw comprising a first contact end, a first contact surface proximate the first contact end, a first interlocking end, and a first pivot disposed between the first contact end and the first interlocking end;

a second arcuate interlocking jaw comprising a second contact end, a second contact surface proximate the second contact end, a second interlocking end, and a second pivot disposed between the second contact end and the second interlocking end; and

in an open state, the first and second arcuate interlocking jaws defining a receiving cavity for receiving the main line, the first contact surface being positioned more remote from the body of the base unit than the second contact surface so that positioning the main line within the receiving cavity causes the first arcuate interlocking jaw to rotate and position about the main line before the second arcuate interlocking moves into position about the main line for interlocking engagement with the first arcuate interlocking jaw; and

a tap defining a passageway, the tap comprising a tapered end having an aperture in fluid communication with the passageway.

11. The saddle tee of claim 10, wherein as the first and second arcuate interlocking jaws are moveable between an open state and a locked state in response to positioning the main line within the receiving cavity, the first interlocking end is positioned closer to the main line than the second interlocking end to enable the first and second interlocking ends to properly mate without manually adjusting the first and second interlocking ends.

12. The saddle tee of claim 10, wherein as the main line is partially positioned within the receiving cavity, the first arcuate interlocking jaw pivots to position about the main line before the second arcuate interlocking jaw pivots to position about the main line in response to the main line contacting the first contact surface before the main line contacts the second contact surface.

13. The saddle tee of claim 10, wherein when a main line is fully positioned within the receiving cavity, the first arcuate interlocking jaw and second arcuate interlocking jaw are positioned about the main line, the first and second interlocking ends being in a locked state with the first interlocking end being positioned closer to the main line than the second interlocking end without manually adjusting the first and second interlocking ends.

14. The saddle tee of claim 10, wherein the first and second arcuate jaws are shaped to deform the main line into a generally elliptical shape when the first and second arcuate jaws are in a locked state.

15. The saddle tee of claim 10, wherein the body defines female threads surrounding the opening for interfacing with male threads on the tap.

16. The saddle tee of claim 10, wherein the tap comprises a fitting with a gripping mechanism that grasps an end of a conduit without annular grooves, annular flanges, or annular beads to secure the end of the conduit within the fitting.

17. The saddle tee of claim 10, wherein the tap comprises a fitting with female threads for receiving a conduit.

18. A saddle tee for use in branching a conduit from a main line, the saddle tee comprising:

a base unit defining an opening for receiving a tap, the base unit comprising a first interface surface having a first series of linearly aligned ridges and further comprising interlocking jaws for securing the base unit to the main line; and

a tap defining a passageway, the tap comprising;

a first end having a shoulder including a second interface surface having a second series of linearly aligned ridges that aligns and seats with the first interface surface to limit rotation of the tap relative to the base unit when the tap is fully inserted into the base unit such that a threshold level of torque is required to rotate the tap relative to the base unit, the threshold level of torque being in excess of that which is likely to be reached without human intervention; and

a tapered end having an aperture in fluid communication with the passageway.

19. The saddle tee of claim 18, wherein the tap comprises a fitting with a gripping mechanism that grasps an end of a conduit without annular grooves, annular flanges, or annular beads to secure the end of the conduit within the fitting.
