Glove-mounting apparatus for explosion-proof lighting devices

Claim 1

A globe mounting apparatus for explosion-proof devices comprising a lighting body which holds an electric light inside, a globe member and a hinge which joins the lighting body and the globe member, said lighting body containing, at the periphery of the opening thereof, a circular flat body containing a circular groove formed on the outside of the flat surface and towards the inside of the lighting body, said circular body being provided with cuts and projections at the periphery thereof, said projections having bolts fastened to the surface thereof which protrude slightly into said circular groove, said globe member made up essentially of a globe holder and a globe, said globe holder containing, at the periphery thereof, a circular flat body provided with clamps located below the circular flat body in a number corresponding with the number of cuts provided at the opening of the lighting body and being shorter than said cuts, said globe holder containing packing underneath said circular flat body and wherein the globe member is secured to the lighting body by inserting the clamps on the globe holder into the cuts in the opening of the lighting body and twisting it clockwise so that the clamps fit into the grooves located on the upper part of said projections and the bolts on said projections are tightened from the underside to hold the clamps securely in the said grooves on the lighting body, whereby the circular flat body located on the lighting body is held firmly against the circular flat body located on the globe member to form a substantially airtight seal between the globe member and lighting body.
