Abstract
Abstract An electric gaslight simulative for installation in an existing candelabra-type light fixture by merely removing the existing bulb and installing the simulative and placing a cylindrical bulb in the socket thereby converting the light fixture into a light which produces a glow or illumination quite similar to that produced by an actual gaslight and having external physical appearance characteristics simulative of an actual gaslight. The simulative includes an adapter body constructed of insulative material positioned on an existing candelabra-type light bulb socket mount and held in place by the generally cylindrical light bulb that telescopes into a generally cylindrical, closed end mantle of glass cloth or similar material with the mantle being supported removably from the adapter body and being supported by a wire frame with both the mantle and wire frame being removable to enable replacement of the elongated cylindrical light bulb. The open end of the mantle is provided with a reinforcing metallic foil tape bonded thereto with the open end of the mantle and tape being received telescopically into a peripheral groove formed in the body of the adapter.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
An assembly to enable an electric light fixture to be converted to a simulated gaslight comprising an adapter having means engaged with the light socket mount on the light fixture and having a bore for a light bulb to extend therethrough and into a socket of said light socket mount, a flexible glass cloth mantle supported from the adapter in a distended position in enclosing relation to a generally cylindrical light bulb whereby illumination of the light bulb will produce a light glow similar to that produced by a gaslight, and means disposed externally of the mantle detachable supporting the mantle from the adapter to enable removal and replacement of the light bulb.
Claim 2
Dependent Claim
113 words
An assembly to enable an electric light fixture to be converted to a simulated gaslight comprising an adapter having means engaged with the light socket mount on the light fixture and having a bore for a light bulb to extend therethrough and into a socket of said light socket mount, a flexible glass cloth mantle supported from the adapter in a distended position in enclosing relation to a generally cylindrical light bulb whereby illumination of the light bulb will produce a light glow similar to that produced by a gaslight, and means disposed externally of the mantle detachable supporting the mantle from the adapter to enable removal and replacement of the light bulb.
Claim 3
Dependent Claim
57 words
The assembly as defined in claim 1 wherein said adapter includes a body of insulative material, and said means supporting said mantle including a supporting wire frame connected to the body and extending alongside the mantle and supporting the outer end of the mantle to simulate a gaslight when the light bulb within the mantle is energized.
Claim 4
Dependent Claim
52 words
The assembly of claim 2 wherein said body includes a pair of laterally extending ears having a socket therein, said wire frame including spaced legs having terminal ends frictionally and detachably secured in the sockets in the ears to enable removal of the wire frame and mantle for replacement of the bulb.
Claim 5
Dependent Claim
57 words
The assembly as defined in claim 3 wherein said mantle is constructed of flexible glass cloth having a closed outer end, means securing the closed outer end of the mantle to the wire frame, the inner end of the mantle being open and provided with a peripheral reinforcing member to stabilize the open end of the mantle.
Claim 6
Dependent Claim
49 words
The assembly as defined in claim 4 wherein the means stablizing the open end of the mantle includes a tape extending peripherally of the open end of the mantle and constructed of metallic foil having a reflective outer surface and an adhesive inner surface for mounting on the mantle.
Claim 7
Dependent Claim
51 words
The assembly as defined in claim 5 wherein said body includes a peripheral channel forming an outwardly opening groove telescopically receiving the open end of the mantle with the metallic foil tape being on the outside of the mantle and forming a telescopic friction engagement with the groove in the body.
Claim 8
Dependent Claim
50 words
The assembly as defined in claim 6 wherein said light bulb is an elongated generally cylindrical bulb having a filament adjacent the outer end thereof for positioning the source of light adjacent the outer end of the filament thereby closely simulating the glow produced by a gaslight with a mantle.
Claim 9
Dependent Claim
92 words
The assembly as defined in claim 1 wherein said adapter comprising a body having said bore therethrough for telescopically receiving the outer end of a plastic tube forming a portion of a candelabra light socket, said cylindrical light bulb including a rigid transparent envelope having a filament therein and a base for mounting in the candelabra light socket, said body including an outwardly facing seat for engagement with the inner end of the envelope of the bulb when it is mounted in the socket for securely mounting the body from the socket.
Claim 10
Dependent Claim
25 words
The assembly as defined in claim 8 wherein said bore through the body includes a shoulder limiting insertion of the plastic tube into the body.
Claim 11
Dependent Claim
39 words
The assembly as defined in claim 9 wherein said body includes an outwardly facing groove coaxial with the bore for receiving the inner end of the mantle when positioned in enclosing relation to the envelope of the light bulb.
Claim 12
Dependent Claim
33 words
The assembly as defined in claim 10 wherein said mantle includes a reinforcing member around the open end thereof for reception in the groove for stabilizing the inner open end of the mantle.
Claim 13
Dependent Claim
38 words
The assembly as defined in claim 11 wherein said means supporting said mantle includes a frame mounted on said body and extending outwardly therefrom, means on said frame engaged with and supporting the outer end of said mantle.
Claim 14
Dependent Claim
40 words
The assembly as defined in claim 12 wherein said frame is a U-shaped wire frame, said body including a pair of sockets detachably receiving the ends of the legs of the frame to enable replacement of the bulb and mantle.
