Abstract

An attachment assembly for each end of an ultraviolet light lamp positioned in a quartz sleeve protruding through a mounting nipple on opposite ends of an apparatus such as a water treatment unit. A compression nut is threadly mounted on each of the mounting nipples and has an internal cylindrical bore with an O-ring for receiving and positioning the end of the quartz sleeve. An elastic electrical socket assembly is operably connected to each end of the ultraviolet light lamp. A retainer is detachably mounted on the compression nut and has means for retaining the electrical socket assembly in position. A compression spring is provided in one of the retainers to resiliently urge the electrical socket assemblies into engagement with the ends of the lamp continuously and securely.

Claims

1. An attachment assembly for the end of an ultraviolet light lamp positioned in and movable relative to a quartz sleeve protruding through and movable relative to a nipple fixedly mounted on and extending from an enclosed apparatus subject to internal pressure, comprising:

a compression nut for detachably mounting on the nipple in sealing relationship and having an internal cylindrical bore smaller than an internal bore of the nipple for receiving and positioning the end of the quartz sleeve;

an electrical socket assembly for operably receiving and electrically connecting to the end of the ultraviolet light lamp; and

a retainer for detachably mounting on the compression nut and having means for retaining the electrical socket assembly in position.

2. The attachment assembly of claim 1, wherein said compression nut has a groove for receiving an O-ring, said O-ring sealably engaging and supporting the quartz sleeve.

3. The attachment assembly of claim 1, wherein said compression nut includes an inwardly extending flange for axially retaining the quartz sleeve in the apparatus.

4. The attachment assembly of claim 1, wherein said electrical socket assembly has a neck portion for inserting into the quartz sleeve in fitting relationship.

5. The attachment assembly of claim 1, wherein said retainer has a chamber for closely confining said electrical socket assembly.

6. The attachment assembly of claim 5, wherein said chamber is of slightly larger axial and radial size than said electrical socket assembly for allowing limited movement of said electrical socket assembly within said compression nut.

7. The attachment assembly of claim 1, wherein said retainer has a chamber for receiving said electrical socket assembly, said chamber having an axial length substantially longer than said electrical socket assembly, and resilient means in said chamber urging said electrical socket assembly toward the lamp.

8. The attachment assembly of claim 7, wherein said electrical socket assembly is axially slidable within said chamber.

9. The attachment assembly of claim 1, wherein said retainer is threadly connected to said compression nut.

10. The attachment assembly of claim 1, wherein said electrical socket assembly has an elastic neck portion for resiliently engaging and gripping the lamp.

11. The attachment assembly of claim 1, wherein said retainer has a knob portion extending away from the apparatus, said knob portion being of a smaller diameter than the rest of the retainer for ease of manual gripping.

12. An attachment assembly for the end of an ultraviolet light lamp positioned in a quartz sleeve protruding through a nipple on an apparatus, comprising:

a compression nut for detachably mounting on the nipple and having an internal cylindrical bore for receiving and positioning the end of the quartz sleeve;

an electrical socket assembly for operably receiving the end of the ultraviolet light lamp; and

a retainer for detachably mounting on the compression nut and having means for retaining the electrical socket assembly in position;

wherein said electrical socket assembly has an electrical wire extending axially from the center of an end of the electrical socket assembly away from the lamp for supplying electricity to the lamp, and said retainer has a radial slot for allowing the retainer to be installed on and removed from the wire laterally without disconnecting the wire from an electrical source.

13. The attachment assembly of claim 12, wherein said compression nut has a groove for receiving an O-ring, said O-ring sealably engaging and supporting the quartz sleeve.

14. The attachment assembly of claim 12, wherein said compression nut includes an inwardly extending flange for axially retaining the quartz sleeve in the apparatus.

15. The attachment assembly of claim 12, wherein said electrical socket assembly has a neck portion for inserting into the quartz sleeve in fitting relationship.

16. The attachment assembly of claim 12, wherein said retainer has a chamber for closely confining said electrical socket assembly.

17. The attachment assembly of claim 16, wherein said chamber is of slightly larger axial and radial size than said electrical socket assembly for allowing limited movement of said electrical socket assembly within said compression nut.

18. The attachment assembly of claim 12, wherein said retainer has a chamber for receiving said electrical socket assembly, said chamber having an axial length substantially longer than said electrical socket assembly, and resilient means in said chamber urging said electrical socket assembly toward the lamp.

19. The attachment assembly of claim 18, wherein said electrical socket assembly is axially slidable within said chamber.

20. The attachment assembly of claim 12, wherein said retainer is threadedly connected to said compression nut.

21. The attachment assembly of claim 12, wherein said electrical socket assembly has an elastic neck portion for resiliently engaging and gripping the lamp.

22. The attachment assembly of claim 12, wherein said retainer has a knob portion extending away from the apparatus, said knob portion being of a smaller diameter than the rest of the retainer for ease of manual gripping.

23. An attachment assembly for the ends of an ultraviolet light lamp positioned in and movable relative to a quartz sleeve protruding through and movable relative to nipples fixedly mounted and extending from opposite ends of an enclosed apparatus subject to internal pressure, comprising:

a nut means for detachably mounting on each of the nipples in sealing relationship and having an internal cylindrical bore smaller than the internal bore of the nipple for receiving and positioning the end of the quartz sleeve;

an electrical socket means for each end of the lamp and having means for operably receiving and electrically connecting to the end of the lamp;

a retainer means for detachably mounting on each of the nut means and having means for retaining the electrical socket means in position therein; and

a resilient means mounted in at least one of said retainer means for urging the electrical socket means therein in an axial direction toward the lamp for maintaining said electrical connection.

24. The attachment assembly of claim 23, wherein said electrical socket means are axially movable within each said retainer means and said resilient means maintains said electrical socket means connected to the ends of the lamp.

25. The attachment assembly of claim 23, wherein one of said retainer means is axially longer than the other, and said resilient means comprises a compression spring positioned in said longer retainer means and engaging an axial end of a said electrical socket means.

26. The attachment assembly of claim 23, wherein the apparatus, lamp, quartz sleeve, nipples, nut means, positioning electrical socket means and retainer means have respective axial lengths for providing axial spaces for allowing axial movement of said assembled lamp and electrical socket assemblies resiliently urged in one direction by said resilient means.

27. The attachment assembly of claim 26, wherein said quartz sleeve is axially movable for a small distance limited, by said nut means.

28. An attachment assembly for the end of a lamp positioned in and movable relative to a sleeve protruding through and movable relative to a mounting nipple fixedly mounted on an enclosed apparatus subject to internal pressure, comprising:

an electrical means having a socket for operably receiving and electrically connecting to the end of the lamp; and

means for detachably mounting on the mounting nipple in sealing relationship and having means for retaining said electrical means electrically connected to the lamp and retaining the sleeve in position in the apparatus.

29. The attachment assembly of claim 28, wherein said means for detachably mounting on the mounting nipple includes resilient means for continually and resiliently urging said electrical means into engagement with the lamp for maintaining said electrical connection.
