Electrical heater for a beverage

Claim 2

An electrical heater comprising enclosing means having a body section and a cover section, both provided with walls made of material having both heat and electrical insulating properties, said sections having a fitting relation in closed position, each section being provided with an electrical heating coil having contacts at its opposite terminal ends, means to hold the coils attached to said walls, the fitting relation of said sections causing said contacts of the coil in one section to engage the contacts of the coil in the other section to place said section coils in series and an insulated electrical cord extending from one of said coils to a source of electrical energy for causing current to pass through both coils when the sections are in fitted closed relation, said current flow beinG interrupted when said body and cover sections are separated, a tray is located beneath said heater, mounting means securing said body section to said tray to provide a better support therefor.

Claim 3

An electrical heater as recited in claim 1 said tray having means to attach it to an automobile seat.

Claim 4

An electrical heater comprising a body section and a cover section each in the form of a hollow shell whereby a completely enclosed storage chamber is formed therewithin when the sections are fitted together, both have walls made of material having both heat and electrical insulating properties, said sections having a fitting relation in closed position, each section being provided with an electrical heating coil having contacts at its opposite terminal ends, means to hold the coils attached to said walls comprising substantially vertically oriented inwardly opening channels, the fitting relation of said sections causing said contacts of the coil in one section to engage the contacts of the coil in the other section to place said section coils in series, said contacts in each section being substantially circular so that they pass around the mouths of the respective cover and body sections and being of an arched cross section whereby a closed circuit is formed no matter at which position the top and bottom sections are fitted together and an insulated electrical cord extending from one of said coils to a source of electrical energy for causing current to pass through both coils when the sections are in fitted closed relation, said current flow being interrupted when said body and cover sections are separated.

Claim 5

An electrical heater comprising a body section and a cover section each in the form of a hollow shell whereby a completely enclosed storage chamber is formed therewithin when the sections are fitted together, both have walls made of material having both heat and electrical insulating properties, said sections having a fitting relation in closed position, each section being provided with an electrical heating coil having contacts at its opposite terminal ends, means to hold the coils attached to said walls comprising substantially vertically oriented inwardly opening channels, the fitting relation of said sections causing said contacts of the coil in one section to engage the contacts of the coil in the other section to place said section coils in series, said contacts in each section being substantially circular so that they pass around the mouths of the respective cover and body sections and being of an arched cross section whereby a closed circuit is formed no matter at which position the top and bottom sections are fitted together and an insulated electrical cord extending from one of said coils to a source of electrical energy for causing current to pass through both coils when the sections are in fitted closed relation, said current flow being interrupted when said body and cover sections are separated.

Claim 6

An electrical heater comprising a body section and a cover section each in the form of a hollow shell whereby a completely enclosed storage chamber is formed therewithin when the sections are fitted together, both have walls made of material having both heat and electrical insulating properties, said sections having a fitting relation in closed position, each section being provided with an electrical heating coil having contacts at its opposite terminal ends, means to hold the coils attached to said walls, the fitting relation of said sections causing said contacts of the coil in one section to engage the contacts of the coil in the other section to place said section coils in series and an insulated electrical cord extending from one of said coils to a source of electrical energy for causing current to pass through both coils when the sections are in fitted closed relation, said current flow being interrupted when said body and cover sections are separated, a light bulb viewably mounted in an aperture in said cover section, thermostatically operated means mounted within said cover section to shunt a portion of the current running through the coil in the cover section through said light bulb upon the chamber reaching a predetermined temperature.

Claim 7

An electrical heater comprising a body section and a cover section each in the form of a hollow shell whereby a completely enclosed storage chamber is formed therewithin when the sections are fitted together, both have walls made of material having both heat and electrical insulating properties, said sections having a fitting relation in closed position, each section being provided with an electrical heating coil having contacts at its opposite terminal ends, means to hold the coils attached to said walls, the fitting relation of said sections causing said contacts of the coil in one section to engage the contacts of the coil in the other section to place said section coils in series and an insulated electrical cord extending from one of said coils to a source of electrical energy for causing current to pass through both coils when the sections are in fitted closed relation, said current flow being interrupted when said body and cover sections are separated, a light bulb viewably mounted in an aperture in said cover section, thermostatically operated means mounted within said cover section to shunt a portion of the current running through the coil in the cover section through said light bulb upon the chamber reaching a predetermined temperature.
