Definitions
- This invention relates to a filament mounting structure for an electric incandescent lamp and has for its principle object to overcome the possibility of vaporized filament material deposited on the film carrier from short circuiting or otherwise causing a defect in the lamp.
- an incandescent lamp in which a pair of spaced vertical carriers are mounted on a support and a pair of transverse insulated carriers are secured to the vertical carriers. is suspended within the space defined by said carriers by securing means spaced from said transverse carriers and connected at one end to said filament and connected at the other end at a point on one of said transverse carriers located in a position remote from said filament.
- the securing means for attaching the transverse carrier to the vertical carriers are connected at one end to the vertical carrier and at the other to a point on the transverse carrier remote from said filament.
- the cross-section of the said carrier may be shaped in many different forms. If the cross-section is circular it will in certain cases be preferable for this transverse carrier to have a groove recessed in it at its side more remote from the filament, in which groove the points at which the supporting wires emerge are arranged.
- Fig. 1 is a front elevational view of a projection lamp in which the filament is stretched in a plane;
- Fig. 2 is a side view of the filament according to the invention partially in section and partially in elevation;
- Figs. 3 and 4 are modifications of the device shown in Fig. 2, and
- Fig. 5 shows the connection of the carriers according to the invention.
- a lamp bulb 1 has vertically extending longitudinal carriers 2 with a U-shaped profile which at 3 terminates in current supply pins 4 which extends so as to project beyond the lamp. These current supply pins are sealed to a dish-shaped glass 5 to which the glass bulb 1 itself is sealed at the zone 6.
- the dish-shaped part 5 includes an exhaust tube at 7.
- transverse carriers 8 and 9 are arranged consisting of porcelain rods of circular cross-section.
- Metal wires 10 projecting from the end faces of transverse rods 8 and 9 are secured to the longitudinal carriers 2 by soldering.
- This filament shown in the embodiment of Fig. 1 consists of six members with its ends secured to the longitudinal carriers 2.
- the filament is maintained in the position shown by means of the securing means such as supporting hooks 12, 13, 14, 15 and 16.
- the supporting hooks 12 and 13 are secured to the transverse carrier 8, the supporting hooks 14, 15 and 2,916,650 F at enter!
- the cross-section of the carrier Fig. 3 shows an embodiment comprising a carrier 17 of triangular cross-section, the apex being turned down.
- Fig. 4 shows a carrier 18 of circular cross-section. It has a groove 19 recessed in it, in the base of which the supporting wires 21 are inserted.
- Fig. 5 which is a perspective view of a modified construction
- a triangular transverse carrier 22 in the upper surface of which not only the supporting hooks 23 and 24 but also the wire 25 joining the transverse carrier 22 to the longitudinal carrier 26 are inserted.
- a conductive layer is not likely to form between the points at which the wires 25 joining the transverse and longitudinal carrier are inserted.
- the points at which the supporting books 23 and 24 are inserted in the upper surface of the carrier 22, are staggered.
- An electric incandescent lamp comprising a support, a pair of spaced longitudinal carriers mounted on said support, a pair of insulated, spaced, transverse carriers secured to said longitudinal carriers, a filament arranged 2.
- Anel tric. incandescentlamp comprising .a supnort apair of spaced longitudinal carriers mounted on saidllsupport, a pair of insulated, spaced, inverted triangular transverse carriers secured to said longitudinal carr iers a filament arranged within the space defined by said carriers, wire securing ,means for maintaining said filament taut and connected at one end to said filament and at the other endvt o one of said transverse carriers atva -point on the base of said triangular transverse vcarrier,
- each of said wire securing means being vfiired to. a surface of saidtransverse carrier on the side thereof opposite to sidethereof racing said filament, said vvire securing ineans approaching said transverse, carrier from the side opposite to the side of securement of said wire securing means to said transverse carrier andbent around said carrier to the point of said securement.
