DOUBLE-ENDED ELECTRIC LAMP AND ASSOCIATED U-SHAPED METAL CLIP Filed Oct. 25, 1959 ITWQTWTOTS: lQe gi naLd d. Agres, Paul, Vargo United States Patent 3,326,466 DOUBLE-ENDED ELETRIC LAMP AND ASSOCI- ATED ill-SHAPED METAL (CLIP Reginald J. Ayres, Shakers Heights, and Paul Vargo,
Lyndhurst, Ohio, assignors to General Electric Company, a corporation of New York Filed Oct. 23, 1959, Ser. No. 848,282 1 Claim. (Cl. 313F618) This invention relates to electrical devices such as incandescent lamps and gaseous discharge devices, and more particularly to electrical devices of the double-ended type having a tubular or otherwise elongated envelope or bulb provided with terminal contacts at its opposite ends. The invention is particularly adapted to relatively small size or miniature type lamps and devices such as are used, for instance, in automobile dome or dash lighting, or for tail lamps.
The production of a satisfactory inexpensive doubleended miniature incandescent lamp of simple construction and adapted for use with simple and inexpensive sockets such as the clip-type sockets commonly used for cartridge fuses, for example, has been a continuing problem in the lamp-making art. Prior proposed lamp constructions of this general type have not been entirely satisfactory for various reasons such as their unadaptability to machine manufacture, or their requirement for production methods which resulted in a high percentage of rejects due to faulty seals, etc., or the formation of socalled gassy lamps. Also, such prior proposed doubleeuded lamps were generally provided with separate metal base members sealed to each end of the lamp which therefore added to the number of parts as well as the number of manufacturing operations required to fabricate the lamp, in addition to adding to the manufacturing cost thereof.
It is an object of our invention, therefore, to provide a double-ended electric lamp or similar device of very simple and inexpensive construction and easy to make, and which is readily adaptable to machine manufacture.
Another object of our invention is to provide a doubleended electric lamp or similar device of the baseless type having its terminal contacts constituted by the leadin wires of the lamp.
Briefly stated, in accordance with one aspect of the invention, the two lead-in wires of an incandescent lamp are sealed into opposite ends of an elongated glass bulb or envelope, through protruding fiat external stem press portions on the envelope at its opposite ends, with the said lead-in wires protruding endwise from and bent around the end of the respective stern press portion to extend back therealong and lie more or less fiat against one of the fiat side faces of the stern press within a gen erally U or V-shaped longitudinal groove therein the depth of which is sufficient to entirely conceal the lead-in wire beneath the surface of the fiat side of the stem press so as to be protected against accidental displacement or bending out of shape during the handling of the lamp and its insertion in and removal from a lamp socket.
Further objects and advantages of our invention will appear from the following detailed description of species thereof and from the accompanying drawing.
In the drawing,
FIG. 1 is an elevation of an electric incandescent lamp comprising our invention.
FIG. 2 is a longitudinal section of the lamp comprising our invention on the line 22 of FIG. 1.
FIG. 3 is a transverse section through the lamp on the line 3-3 of FIG. 1.
FIG. 4 is a perspective view showing a lamp according to our invention inserted in place in a socket.
3,320,455 Patented May 16, 1967 FIG. 5 is a view showing one of the stem press ends of the lamp in section and inserted in place in one of the contact clips of the lamp socket.
FIG. 6 is a fragmentary longitudinal sectional view of one end of a modified form of electric incandescent lamp comprising our invention.
FIG. 7 is a fragmentary perspective view of one end of the modified lamp shown in FIG. 6, and
FIG. 8 is a transverse sectional view, on the line 88 of FIG. 6, of one of the stem press ends of the modified lamp shown in FIGS. 6 and 7.
Referring to the drawing, the electric incandescent lamp there shown comprises a sealed elongated glass bulb or envelope 1 preferably of tubular shape and provided at its opposite ends with reduced diameter neck portions 2 terminating in flat stern press portions 3 through which lead-in wires or conductors 4 are sealed so as to protrude endwise therefrom. Interiorly of the bulb 1 the lead-in wires 4 are connected to the opposite ends of an electrical energy translation element or filament 5 of a suitable refractory metal and preferably in the form of a straight length of coiled tungsten wire supported by the lead-in Wires 4- in a position extending more or less axially of the tubular envelope 1. The envelope 1 contains a suitable inert gas filling such as argon, for example, at a pressure below atmospheric.
As shown in FIG. 2, the protruding flat stem press portions 3 at the opposite ends of the envelope 1 are disposed in the same axial plane of the lamp envelope and are formed with shallow grooves or channelways 6 of generally U or V-shape on one or both of their flat side faces '7. The said grooves 6 extend generally longitudinally of the envelope 1 and they are located more or less centrally of the stem press portions 3 between their side edges. The lead-in wires 4 project outwardly from the outer ends 3 of the stem press portions 4 at points likewise located more or less centrally of the stern press portions, and they are bent back around the said ends 8 of the stem press portions to lie fiat against one or the other of the sides 7 thereof within the respective groove 6 therein so as to be concealed beneath the fiat surface 7 of that side of the stern press along which the lead-in Wire extends. The portions 9 of the lead-in wires 4 thus bent around the stem press portions and lying with- 45 .in the grooves 6 serve as the terminal contacts for the lamp, and because of their concealment within the grooves 6 so as to lie below the flat surfaces 7 of the stem press portions 4, they are thereby protected against distortion by becoming caught on objects and bent out of shape during the handling of the lamp or its insertion and removal from the lamp socket. To permit the concealment of the exposed terminal contact portions 9 of the lead-in wires 4 below the flat surfaces '7 of the stern press ortions 3, the grooves 6 in the said stem press portions are made of a depth slightly greater than the diameter of the said terminal contact wire portions 9.
Because of its particular structural conformation characterized by flat base ends 3 provided with flush-type terminal contacts 9 concealed below the flat surfaces 7 of the base ends 3, the lamp according to the invention is therefore readily adapted for use with exceedingly simple type lamp sockets 10 (FIG. 4) similar to the clip type sockets customarily employed for cartridge type fuses and comprising a pair of spaced U-shaped metal clip contacts 11 mounted on an insulating base 12 and adapted to receive the lamp therebetween and yieldably grip its fiat base ends or stem press portions 3 so as to hold the lamp firmly in place in the socket.
The lamp 1 is inserted in the socket 10 by simply pushing its flat base ends or stem press portions 3 straight down between the two spring arms 13 of the respective contact clip 11 until opposed inward V-shaped indents or portions 14 of the spring arms 13 snap into the grooves 6 in the flat base ends or stem press portions 3 of the lamp to thereby lock the lamp in place in the socket, with the V-shaped indents 14 of one of the spring arms 13 of each clip 11 in spring pressure engagement with the exposed portion 9 of the lead-in wire lying within the bottom of the groove 6 in the stem press 3 so as to make effective electrical contact therewith. As shown in FIGS. 3-5, the stem press portions 3 of the lamp are preferably formed with double beveled side edges 3 to provide V-shaped wedge surfaces for facilitating the insertion of the stem press portions of the lamp between the spring arms 13 of the socket clips 11.
Instead of the terminal contacts of the lamp being constituted by portions 9 of the lead-in wires bent back into the locating grooves 6 in the stern press portions 3 of the lamp, the said terminal contacts may comprise U-shaped metal clip members 15 straddling and suitably secured to the respective stem press portions 3 over the outer ends 8 and the flat sides 7 thereof, as shown in FIGS. 6 to 8. The clip members 15 may be formed of sheet metal strips bent into U-sha-pe to provide two parallel leg or arm portions 16 which fit snugly into channelways or passageways 17 in the opposite fiat sides 7 of the stem press portions 3 so as to lie flush with or below the fiat surfaces thereof, as shown in FIG. 8. The channelways 17 are deepened at their innermost ends to form cavities 18 which provide inwardly facing abutment shoulders 19, and the arms 16 of the clip 15 are formed with in-turned right-angled extremities 20 which extend into the cavities 18 of the channelways 17 and engage with the abutment shoulders 19 to thereby lock the clip in place on the stem press against unwarranted endwise withdrawal therefrom. The metal clips 15 may be made out of springy material so that they will function in the manner of a spring clip to cause the in turned lip ends 20 thereof to snap into place in the deepened portions 18 of the channelways 1'7, and lock the clip in place on the stem press 3, when the clip is pushed the full distance home into the channelways 17. Instead of being formed out of springy material, the metal clips 15 may be made of metal strip material which is merely flexible or bendable, and the metal strip material bent or deformed into place within the channelways 17 and into the deepened inner end portions or cavities 18 thereof.
In order to function as the terminal contacts of the lamp, the metal clips 15 are electrically connected in a suitable manner to the respective lead-in wire 4 to form composite electrical conductors therewith. To this end, the metal clips may be each provided with a central aperture 21 in that portion of the clip which lies opposite and straddles the outer end of the stem press, and the lead-in wire 4 is threaded through the said aperture 21 and suitably secured to the outer side of the metal clip as by soldering or welding it thereto, as indicated at 22.
The manufacture of a lamp constructed according to the invention may be accomplished in a very simple manner by first sealing a lamp mount, comprising the filament 5 and lead-in wires 4 connected thereto, into one end of a glass lamp envelope 1. The atmosphere within the envelope 1 is then flushed out, and replaced by a filling of an inert gas such as argon, by directing a stream of the inert gas into the envelope through its remaining open end. While the inert gas is thus being continuously directed into the open end of the envelope, the open neck end of the envelope is then heated and softened, and compressed around the lead-in wire 4 of the mount, to thereby complete the sealing of the mount into the envelope. The protruding portions 9 of the lead-in wires 4 are then bent around the ends 8 of the stem press portions 3 to lie fiat within the bottoms of the respective grooves 6 in the stem press portions 3, or else are soldered or otherwise connected to the U-shaped contact clips 15 which are applied to the opposite ends of the envelope in the case of the modified form of lamp shown in FIGS. 63.
Although preferred embodiments of our invention have been disclosed, it will be understood that the invention is not to be limited to the specific construction and arrange ment of parts shown, but that they may be widely modified within the spirit and scope of our invention as defined by the appended claim.
What we claim as new and desire to secure by Letters Patent of the United States is:
An electrical device comprising a double-ended sealed glass envelope provided at its opposite ends with protruding flattened external stem press portions disposed in a common plane, each of said flattened stem press portions having parallel channelways in its flat sides extending longitudinally of said envelope and disposed opposite one another, lead-in wires sealed through respective ones of said stem press portions and extending into said envelope, and U-shaped metal clip members straddling the ends of and secured to said stem press portions with their arm portions snugly received within the said channelways in said stem press portions and lying flush with the surfaces of the fiat sides thereof, said metal clip members being electrically connected to respective ones of said lead-in wires to form terminal contacts for the device.
