James Jr. - Web page: https://patentgrep.com/patent/US4393439A ## CPC - F21L 19/00: Lanterns, e.g. hurricane lamps or candle lamps - F21L: LIGHTING DEVICES OR SYSTEMS THEREOF, BEING PORTABLE OR SPECIALLY ADAPTED FOR TRANSPORTATION ## Abstract A hydrocarbon-burning lantern is convertible from a broadcast configuration to a spotlight configuration. The cover, glass housing, and bail of a conventional lantern are removed and replaced with a semi-spherical reflector having a glass-covered opening and a handle. A ring clamps the glass window against the open face of the reflector. A number of vent openings are provided in the reflector to cool the lantern and permit the lantern to be lighted. The handle permits the lantern to be maneuvered effectively. ## Claims ### Claim 1 A reflector for use with a portable lantern having a base portion, a light-emitting element positioned above the base portion, and a translucent housing surrounding the light-emitting element, the reflector adapted to replace the housing and enable the lantern to operate as a spotlight, comprising: (a) a shell disposed about the light-emitting element, the shell having a light-reflective inner surface; (b) openings in the shell to permit the ingress and egress of cooling air; (c) a window secured to the open side of the shell; and (d) a handle attached to the lantern by which the lantern can be readily maneuvered, the handle being positioned on that side of the shell opposite the window. ### Claim 2 (depends on 1) The reflector of claim 1, wherein the shell is semi-spherical. ### Claim 3 (depends on 1) The reflector of claim 1, wherein: (a) the lantern includes at least one vertically extending member to support the light-emitting element; (b) the shell includes an opening at its bottom portion to enable the shell to be fitted about the vertically extending member; and (c) the light-emitting element includes a support near its upper end, the support being attached to the shell to secure the shell in place atop the lantern base. ### Claim 4 (depends on 3) The reflector of claim 3, wherein the handle is attached to the lantern at the connection between the shell and the base portion, and also is attached to the lantern at or near the connection between the support and the shell. ### Claim 5 (depends on 1) The reflector of claim 1, wherein the shell is comprised of aluminum of a thickness suitable for shaping in a stamping operation. ### Claim 6 A hydrocarbon burning lantern suitable for use in one mode as a broadcast lantern and in another mode as a spotlight, the spotlight configuration of the lantern comprising: (a) a base portion for supporting the lantern; (b) a vertically extending spacer projecting from the upper part of the base portion; (c) at least one light-emitting element positioned above the spacer and held in position there by a member extending vertically upwardly from the spacer; (d) a support connected to the vertically extending member and disposed above the upper end of the light-emitting element; (e) a shell having a light-reflective inner surface disposed about the light-emitting element, the shell including a bottom portion adapted to tightly mate with the top of the spacer, the shell including an opening near its upper portion by which the shell can be secured to the support; (f) a window fitted to the open side of the shell; and (g) a handle positioned on the opposite side of the shell from the window and secured to the lantern at the interface between the spacer and the shell, the handle also being secured to the lantern at the interface between the support and the opening in the upper portion of the shell. ### Claim 7 (depends on 6) The lantern of claim 6, wherein the shell is semi-spherical. ### Claim 8 (depends on 6) The lantern of claim 6, wherein the shell includes openings near its lower portion for admitting cooling air and for permitting the lantern to be lighted, the shell also including openings located near the window to permit heated air to be exhausted from the shell. ### Claim 9 (depends on 6) The lantern of claim 6, wherein the handle comprises: (a) a vertically oriented member having an enlarged upper portion; (b) a first brace connecting the enlarged upper portion of the handle to the support; and (c) a second brace connecting the lower portion of the vertically oriented member to the lantern at the interface between the shell and the spacer. ### Claim 10 (depends on 6) The lantern of claim 6, wherein the window is held in place by a band extending circumferentially about the periphery of the shell. ### Claim 11 A reflector for use with a portable lantern having a base portion, a light-emitting element positioned above the base portion, a translucent housing surrounding the light-emitting element, a vertically extending member projecting upwardly from the base portion, the vertically extending member supporting the light-emitting element, and a support connected to the vertically extending member and disposed above the upper end of the light-emitting element, the reflector adapted to replace the housing and enable the lantern to operate as a spotlight, comprising: a semi-spherical shell having a light-reflective inner surface disposed about the light-emitting element, the shell including a bottom portion adapted to mate with the top of the base portion, the shell including an opening near its upper portion by which the shell can be secured to the support, the shell also including openings near its lower portion for admitting cooling air and for permitting the lantern to be lighted, the shell additionally including openings located near the open side of the shell to permit heated air to be exhausted from the shell; a window fitted to the open side of the shell, the window being held in place by a band extending circumferentially about the periphery of the shell; and a handle positioned on the opposite side of the shell from the window and secured to the lantern at the interface between the spacer and shell, the handle also being secured to the lantern at the interface between the support and the upper portion of the shell, the handle including: a vertically oriented member having an enlarged upper portion; a first brace connecting the enlarged upper portion of the vertically oriented member to the support; and, a second brace connecting the lower portion of the vertically oriented member to the lantern at the interface between the shell and the base portion.
