LAMP AND LAMP MOUNTING Filed Nov. 13, 1930 I INVENTOR PHIL/P d. KENT AND 7 EELATTORNEY Patented Apr. 25, 1933 UNITED STATES PATENT OFFICE PHILIP J. KENT, OF BIRMINGHAM, AND IAN C. MCKECHNIE, 013 DETROIT, MICHIGAN, ASSIGNORS TO CHRYSLER CORPORATION, 013 DETROIT, MICHIGAN, .A-CORPORATION OI DELAWARE LAMP AND LAMP MOUNTING Application filed November 13, 1930. Serial No. 495,461.
This invention relates to an improved lamp and lamp mounting, particularly for instrumerit boards of vehicles, radios and the like.
' The main objects of the invention are to provide means for securing a lamp of this kind to a support; to provide integral bayonet joint elements on a lamp mounting which are adapted to secure the lamp to a support without the aid of separate attaching members such as screws, bolts and rivets; and to provide a lamp mounting of lmproved construction in which the joint between the mounting and a support is completely obsoured from viewwhen the lamp is installed.
Further objects of the invention are to provide yielding means which bear between the lamp mounting and one side of its support for frictionally resisting turning of the lamp; to provide resilient means of this kind which are placed under compression during installation of a lamp on a support and which remain under compression thereafter retaining the lamp in a position substantially normal to the surface of its support; and to provide an improved lamp of this character which is of simple and inexpensive construction.
An illustrative embodiment of the invention is shown in the accompanying drawing, in which: i
Fig. 1 is a central vertical section of the lamp and lamp mounting which embodies our invention.
Fig. 2 is a transverse vertical section taken on the line 22 of Fig. 1.
Fig. 3 is a central vertical section of a lamp and lamp mounting embodying a modified form of the invention.
Fig. 4 is a transverse vertical section taken "on the line 44 of Fig. 3.
In the form shown in Figs. 1 and 2, our improved lamp mounting includes a cylindrical tubular member 1 comprising sheet metal material-and having an unrestricted open end 2 for receiving the base portion 3 of an electric light bulb 4. The open end portion of the tube 1 is provided with diametrically'opposite, L shaped slots 5 for receiving pins 6 on the periphery of the base 3 of the bulb.
Extending into the opposite ends of the tube 1 is a contact member or bar 7 on the inner end of which is mounted a disc 8 which is formed ofinsulating material, such as fiber, rubber or bakelite. Spaced sections of the left end portions of the tube 1 are bent in disc 11 has a central aperture 13 which is larger in diameter than the rod 7 and which permits free and unobstructed movement of the rod and the disc 8 is held against displacement from the right end of the rod 7 by an enlarged head or contact element 14 which engages a contact element 15 of the light bulb and yieldably urges the latter outwardly so as to firmly hold the pins 6 of the light bulb against the circumferential edge 16 of the L shaped slot 5.
Those portions of the sides of the tube 1 which are located between the extremities of the inwardly extending flanges 9 and 10, are bent outwardly so as to provide outwardly extending, radial lugs or bayonet joint elements 17 and 18 at diametrically opposite lo cations on the tube 1. Mounted on the outer periphery of the tube 1, between the opposite ends thereof, is an annular ring 19 having an inner cylindrical portion 20 in which the tube 1 is received, and an outwardly offset cylindrical portion 21 forming an annular channel around the periphery of the tube. A ieldable cushion element 22 comprising resilient material, such as rubber, located in the channel formed by the ring 19, has an exposed end which extends through the open side of the channel and terminates in close proximity to the bayonet joint elements 17 and 18. r
In installing a lamp and mounting of this kind on a support 23, such as an instrument I board of a vehicle or a panel of a radio, the .support is provided with a circular "opening 24 of a diameter slightly larger than the outer diameter of the tube 1 and having communicating radial slots 25 for receivin the lugs 17 and. 18 of the tube. The 10 tated to a locked position.
endoii the tube .1 and the lugs 17 and 18 are inserted throu h the opening 24 and slots 25, respective y and the tube is then rotated through substantially 90 so as to move the lugs out of registration with the slots 25. As the exposed end of the yieldable member 22 is normally spaced from the lugs 17 and 18 an amount less than the thickness of the support 23, it is necessary to compress this yieldable element in order to move the lugs beyond the inner surface 26 of the support so as to permit the tube 1 to be ro- This compression of the yieldable member 22 causes the support to be clamped between the lugs 17 and 18 and the exposed end of the yieldable element. Unintentional rotation of the bulb from its locked position is frictionally prevented by the exposedend of the yieldable member 22 which bears upon the outer surface 27 of the support. V
The entire mounting including the tube 1, bulb 4, ring 21 and yieldable element 22 is enclosed by a casing 28 having a flared end portion 29 which is seated upon and piloted y the periphery of the ofiset' cylindrical portion 21 of the ring 19. This casing has a sightly contour and it completely obstructs all elements of the lamp mounting from view. The casing 28 has a light emitting slot 30 which is covered by a transparent member 31 located in the interior of the cas-' %n the form shown in Figs. '3 and 4, the lamp mounting includes a tubular member 1' having'an open end 2' for receiving the base portion 3' of a light bulb .4. The tube 1' has a pair of L shaped slots 5. for accommodating ins 6 on the outer periphery of the base 3 Extending into the other end of the tube 1 is a contact bar-7 having a head 14 on its inner end which engages the contact element 15 of the light bulb. .The bar 7" is urged inwardly by a spring 12' which bears between an insulating disc 8' mounted on the inner end of the rod 7 and an insulating disc 11' which is seated against the inwardly extending flanges '10 on the opposite sides of the left end 'portion' of the tube 1.
Formed on the left end of the tube 1', as viewed in Fig. 3, are diametrically opposite, outwardly extending radial lugs 17 and 18' which serve as bayonet joint elements and which extend through slots in a support 23 that communicate with a circular opening 24' of the support. A ring 19 having an in ner cylindrical portion 20 in which the tube 1 is received and an offset cylindrical portion 21, is welded orotherwise secured to the outer periphery of the tube 1 at 32. The olfset cylindrlcal portion 2150f the ring 19 has an inwardly extending flange 33 from which arms 34 are struck out. These arms extend outwardly fromthe flange 33 to within close proximity of the lugs 17' and 18. When the flanged end of the tube 1 is inserted through the opening 24 of the support 23', the arms 34 resiliently bear upon the outer surface 27 of the support and firmly hold the lugs 17 and 18' against the inner surface.
26 of the support. These arms frictionally resist unintentional turningof the tube 1' from its locked position and they hold the lamp mounting substantially normal to the support.
The lamp mounting shown in Figs. 3 and 4 is also provided with a casing 28 having a flared portion 29 which is seated upon the outer periphery of the oflset cylindrical part 21' of the ring 19. Formed in the easing 28 is a light emitting slot 30' which is covered by a transparent element 31 located in the casin A lamp 0 either of the above constructions may be conveniently mounted on a support by simply pressing the left end portion of the tube through an aperture in the support against the resistance of the yieldable elements and then turning the tube until the lugs thereof are out of registration with the slots of the support in which they are received during insertion of the mounting and the lamp may be as easily removed from the support by turning the tube until the lugs thereof register with their slots.
Although but several specific embodiment of this invention have herein been shown and described, it will be understood that various changes in the size, shapeand arrangement of parts may be made without departing from the spirit of our invention and it is not our intention toelimit its scope other than by the terms of the appended claims.
