A lamp construction, in combination ma pass. said pins 17 extending inwardly with a casing member, and a. closu're memand radially from the lamp closure or lens her for said casing, of means for securing said closure member thereon, including a pin on one of said members, a lever fulcrumed substantially midway between its ends to the other member, said lever being provided with a notch in one end thereof adapted to engage and hold said a compression spring mounted between the opposite end of said lever and the member upon which it is mounted for normally maintaining the notched end thereof in engagement with said pin, whereby said pin maybe moved out of engagement with said lever upon the compression of said spring.

2, A lamp construction, in combination with a casing member, and a closure member for said casing, of means for securing said closure member thereon, including a.

passageway in one of said members, a pin on the other member adapted to extend into said passageway, a substantially straight lever'fulcrumed between its ends to the passageway bearing member having one end thereof in position to engage said pin, and yielding means mounted at the other end of said lever on the opposite side of said fulcrum from the engaging end thereof for yieldingly maintaining it in engagement with'said pin.

3. A lamp construction, in combination with a casing member, and a closure, memher for said casing, of means for securing said closure member thereon, including a passageway in one of said members, a pin on the other member adapted to extend into said passageway, a lever fulcrumed to the passageway bearing member having one end thereof in position to engage and retain said pin, yielding means mounted at the other end of said lever for yieldingly maintaining it in engagement with said pin, and a bearing plate adjacent the fulcrum point of said lever adapted to extend through a pin, and

suitable opening in said last mentioned member.

4. A lamp construction, in combination with a casing member, and a. closure member for said casing, f means for securing said closure member thereon, including a passageway in one of said members, a pin on the other member adapted to extend into said passageway, a lever fulcrumed to said passageway bearing member having a notch in one end thereof adapted to engage and hold said pin, and a spiral compression spring mounted between the opposite endof said lever and said passageway bearing member for normally maintaining the notched end of said lever in engagement with said pin, whereby said I pin may be moved out of engagement with said lever and out of passageway upon the comp-ression of said spring. 7 p v 5. A lamp construction, in combination with a casing member, and a closure member for said casing, of means for securing said closure member thereon, including a passageway in one of said members, a pin on the other member adapted to extend into said passageway, alever having a notched end adapted to engage said pin, means near the center of said lever for pivotally securing it to said passageway bearing member, and a compression spring positioned between the otherend of said lever and said passageway bearing member for normally forcing the notched end thereof into engagement with said pin, the spring engaged end of said lever extending through an opening in said last mentioned member to the opposite side thereof so as to provide a guide for the movement ofsaid lever.

In witness whereof, I" have hereunto aflixed my signature.
