I claim: 1. An apparatus for lowering a wireline into a well, the apparatus comprising: a sleeve having a first end and a second end, wherein said first end contains a first plurality of wedges and the second end contains a second plurality of wedges; an upper mandrel having a third plurality of wedges that are configured to engage the first plurality of wedges; a first cap configured to engage the upper mandrel, wherein said first cap contains a first passage and a second passage, and wherein said first passage is configured to receive the wireline; a lower mandrel having a fourth plurality of wedges that engage with the second plurality of wedges; a second cap configured to engage the lower mandrel, wherein said second cap contains an opening, wherein said opening has the lower mandrel disposed there through; thread means on an inner portion of the first cap; thread means on an outer portion of the sleeve which cooperates with the thread means on the inner portion of the first cap. 2. The apparatus of claim 1 further comprising: thread means on an inner portion of the second cap; thread means on the outer portion of the sleeve which cooperate with the thread means on the inner portion of the second cap. 3. The apparatus of claim 2 further comprising: first seal means on an inner portion of the sleeve; a first cooperating seal bore on the upper mandrel for sealingly engaging the first seal means; second seal means on the inner portion of the sleeve; a second cooperating seal bore on the lower mandrel for sealingly engaging the second seal means. 4. The apparatus of claim 3 wherein said second passage is configured to receive a kill line means for pumping a fluid into the well. 5. An apparatus for lowering a wireline into a well, the apparatus comprising: a sleeve having a first end and a second end, wherein said first end contains a first plurality of wedges and said second end contains a second plurality of wedges, said sleeve containing a bore having a center axis; an upper mandrel having a third plurality of wedges that are configured to engage the first plurality of wedges, and wherein said upper mandrel has a center axis aligned with the center axis of said sleeve bore; a first cap configured to engage the upper mandrel, wherein said first cap contains a first passage in communication with said bore and wherein said first passage is adapted to receive the wireline; a lower mandrel having a fourth plurality of wedges that engage with the second plurality of wedges; a second cap configured to engage the lower mandrel, wherein said second cap contains an opening, wherein said opening has the lower mandrel disposed there through; first thread means on an inner portion of the first cap; second thread means on an outer portion of the of sleeve which cooperates with the first thread means. 6. The apparatus of claim 5 further comprising: third thread means on an inner portion of the second cap; fourth thread means on the outer portion of the sleeve which cooperate with the third thread means. 7. The apparatus of claim 6 wherein said first cap contains a second passage in communication with said bore, and wherein said second passage is configured to receive a second wireline lowered into the well. 8. The apparatus of claim 7 further comprising: first seal means on an inner portion of the sleeve; a first cooperating seal bore on the upper mandrel for engaging with the first seal means. 9. The apparatus of claim 8 further comprising: second seal means on the inner portion of the sleeve; a second cooperating seal bore on the lower mandrel for engaging with the second seal means. 10. The apparatus of claim 7 wherein a center axis of said upper mandrel is aligned with the center axis of said sleeve so that said upper mandrel provides a center of pull for the apparatus. 11. An apparatus for lowering a wireline into a well, the apparatus comprising: a sleeve having a first end and a second end, wherein said first end contains a first torque shoulder and the second end contains a second torque shoulder; an upper mandrel having a third torque shoulder that is configured to engage the first torque shoulder; a first cap configured to engage the upper mandrel, wherein said first cap contains a first passage and a second passage, and wherein said first passage is configured to receive the wireline; a lower mandrel having a fourth torque shoulder that is configured to engage the second torque shoulder; a second cap configured to engage the lower mandrel, wherein said second cap contains an opening, wherein said opening has the lower mandrel disposed there through; first thread means on an inner portion of the first cap; second thread means on an outer portion of the sleeve which cooperate with the first thread means on the inner portion of the first cap. 12. The apparatus of claim 11 wherein said second passage is configured to receive a kill line means for pumping a kill fluid into the well. 13. A method of performing wireline work on a rig, wherein a well extends from the rig, and wherein the method comprises: providing an apparatus comprising: a sleeve having a first end and a second end, wherein said first end contains a first plurality of wedges and the second end contains a second plurality of wedges; an upper mandrel having a third plurality of wedges that are configured to engage the first plurality of wedges; a first cap configured to engage the upper mandrel, wherein said first cap contains a first passage and a second passage, and wherein said first passage is configured to receive the wireline; a lower mandrel having a fourth plurality of wedges that engage with the second plurality of wedges; a second cap configured to engage the lower mandrel, wherein said second cap contains an opening, wherein said opening has the lower mandrel disposed there through; providing a wireline through said first passage and into a central bore of said sleeve, and wherein said wireline has a down hole tool attached at a first end, wherein the down hole tool is in the well; lowering the down hole tool on the wireline into the well, transmitting a torque to the upper mandrel; transmitting the torque to the third plurality of wedges; transferring the torque to the first plurality of wedges. 14. The method of claim 13 further comprising: terminating the torque to the upper mandrel; transmitting the torque to the lower mandrel; transmitting the torque to the fourth plurality of wedges; transferring the torque to the second plurality of wedges; pumping a fill fluid through the second passage and into the well.
