EUGENE A. KUEN, 'or ciivor vne'ri, OHIO, Assrenoa TO THE 'srros. QT. oon-conaiv LAMP COMPANY, or oincinlverr, OHIO, A CORPORATION or HIO,

VEHICLE L MP] Application filed June 5,

To all whom it may concern:

Be it known that I, EUGENE A. KUEN, a

icitizen of the United States, residing at .mittin Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in VelncleLamps,

lamps, especially such as are used as headlights on automobiles and other vehicles,

as so-called spot-lights for vehicles, and for other purposes.

It is the object of my invention to provide new and improved means'whereby to-locate the reflector in an electric lamp of the charactermentioned; further, to provide new and improved means whereby to cause pressure upon the reflector; further, to provide novel means whereby to secure a closure in position in a lamp; of the character mentioned; further, to provide new and improved means whereby to relatively position the body, the reflector and the closure,- and to cause pressure between the same; further, to provide new and improved means whereby to locate the light transg plate in the ringmember of the closure; and, further, to providenewand. improved means to seal the space between the light transmitting plates and the re flector and to cushion the light transmitting plate and reflector. 7

The invention will be further readily un- A derstood from thefollowing description and claims, and from the drawings, ii -which latter: Fig. 1 is'aperspective view ofthe body of myimproved device.

My present invention is an improvement upon the device shown, described and claimed in Patent NO.T1,334:,762, issued to me under date of March 23, 1920, for tas toning oevice for automobile lamp closuref The invention is exemplified as applied to an electric lamp having a parobolic reflect: tor 21. The body 22 of the lamp is pretenably of usual parobolic form. Its front end is preferably provided with an annular wall 23, shown as a cylindrical'flange. An annular bead 2-1 is preferably located at the rear end of this annular wall. Aclosure 25 I is provided, exemplified .as comprising a' ring-member 26 having an annular wall 27', shown as a cylindrical fiange and a light transmitting plate 28. v i I Closing meansior the lamp are located between the body and the closure, these I closing means. comprising'springs and complemental contact-members, with which the vided, the body in thepresent exempliit cation being provided with the springs and 'erting pressure in theadirection of its width,

and torsionally. k L The respective ends of the spring are received

insockets

35, 36, which are struck placed on the body but not the closure with the complemental contactthe pin to permit the pin to outwardly from the body of the wall 23,

forming bulges 37 38. The sockets are provided with

slots

39, 40, projecting toward each other, through which tongues41, 452, formed at the respective ends ofthe spring, are received. The sockets are preferably wider than thetongues so as to permit -pivotal shifting of the ends of the tongues in the direction' of width -of the-spring when the spring is flexed. The front walls of the slots form fulcrums on which the ends of the spring are fulcrumed during the flexing :movement of the middle portion of the spring by the movement of the pin along the spring while rotating the closure'for look ing the. closure to thefbody. Shoulders 43,

44, onthe spring coact with the walls of the sock'ets' to position thespring end-wise.

"The middle portion'of the spring normally tween the closure, thereflector and the body.

' The rear edge of the spring is also provided with theforwardly projecting recess 49,

forming a shoulder 50 at the. end of the wedge face of the spring, behind which the.

pin is adaptedto be received when the closure, the reflectorland the body are securely clamped together. The shoulder has a comparatively abrupt incline acting to hold the pin in place during ordinary usage, but per- Initting reverse rotation of the closure by,

forceful action when it is desired to'remove the closure. 7 V

The striking of the

bulges

37, 38, outwardly form friction-relieving riding spots for the wall of the closure for relieving friction when rotating the closure, and the location of the/ends of the springsoutside the annular wall of the body leaves-the inner face of the-annularwall free of obstruction for the ready reception and rotation of the reflector. V V The body is providedwith inwardly extending lips 53 wh ch are'shown struck 1nwardly from therear walls of therecesses 31, Preferably large-r lips 54 are also shown struck inwardly-from the rear walls of said recesses. There is apair of these

lips

53, 54, at-each' of the recesses for locating the reflec tor. The-

lips

53 and 54"are formed out of material between the ends of the recesses-31, which would otherwise be cut away to form "the recesses,*-and are bent inwardly from the rear walls of the recesses, making an exceptionally compact and economical structure. The lips 53 arelocated in axial direction slightly forward of the lips 54; the distance between them in lines parallel'to th'e ai'ris of the lamp being slightly less than the thick-v -ness-of the flange 55 of the reflector. The relative positions of the-lips of therespective pairs of lips is such as to engage the respective forward and rear faces of this fl-ange'and hold the same firmly between them for locating the reflector in" the body.

The reflector is-formed with said flange which, in the form shown, is bent outwardly from a rearwardly eXtendmg flange 56, which extends rearwardlyfrom the front edge "of the'reflector for forming arevers'elybent" front end 57 on the reflector.

The flange 550f the reflector is provided with recesses 58. @ne'ofthe 'c'ornersof'each of these recesses, namely, the "'cori'ier' "59,

which'rnoves toward the llps 53 when ro-v tating the reflector for positioning. of the 're flector in the body, is bent "slightly rearwardly, as shown in Figs. 4 and 7 so as to cause said wallsto be readily receivedrum der' the' lips 53,"when rotatin'gthe reflector.

When the reflector isi-pla'c'ed into thebody of the-lamp, its recesses 58 "are 'broughtinto.

line with the inwardbends 46 of the springs,

' being also "in line with the lips 53 whic lrarein'rear of said bends. :The lips 54 preferably extend inwardly further than the lips "53.

When the reflector is received in the body in the relation started, the flange-0f thereflect-or rests on the lips 54, which fornrlimits for the: inward movement of the reflector. Upon rotation of the reflector, thereflector'rotat'es on the lips 54, and-the corners 59 of'thefrecesses 58 are received under the lips'53, the

'rearwardly bent cornersforming forwardly extending wedge faces for "wedging the flange of the reflector hetween t'he lips "53 and 54.

The lighttransmit-ting plate 28, eXemplie fled as of glass, islocated int-he ring-1nem-" ber preferably against the rear'end' of a I 'rearwardly extending flange 61, which, in the 'QXGIDIOl'lfiCfl-EIOII, forms an inner annular channel 62 in the ring-member. Acushion "64"is at the inner face of the light trans- This cushion is exemplified mitting plate. asa flat annular cush on"and"mayfor instance be a. strip or ring of"car d*board,"or

have fingers 66 which extend rearwardl'y and have inwardly bent ends forming'l ips' '67 111 rear of the cushion,"with the cushion located between the light transmitting plate and the lips, so as to cushion thedipsfanfd thereby avoid "fracture-or da-ma'geto the clips 65 are located in the-ring-memberarid 7 Gil edge of the light transmitting plate. The cushion also acts as a cushioning means between the light transmitting plate and the forward end of the reflector, movable with the closure. I

The clip is preferably formed of a single piece of sheet metal and. comprises a body-portion 68, provided with a bend 69, extending into the channel 62 of the closure, and with the fingers 66, The clip is provided with a hole 70, the annular wall of the closure being provided with a mating hole 7]. A rivet is received through these holes, the head 72 of the rivet being at the outside of the closure. The inner end of the rivet is thereupon upset upon the clip to form the inner shoulder 73, for rigidly securing the wall, the clip and the rivet together, the inner end of the rivet forming the pin 83 of the closure which coacts with the spring 32.

When the closure is applied to the body, and the pins have passed through the recesses formed by the bends 4:6 in the springs, as hereinbefore explained, the reflector havingbeen placed in the body, a relative rotation between the closure and the body will cause movement of the pins alongthe rear edges or wedge faces of the springs, thereby drawing the closure andthe body toward one another, and causing pressure upon the cushion 64, located between the light trans- -mitting plate and the forward end of the reflector. The outwardly struck bulges 37,- 38, which form the

sockets

35, 36, receiving the ends of the springs, form centering means for the ring-member of the closure, the inner face of the annular wall of the closure riding on these bulges and thereby centering the ring-member withrelation to the body and reducing friction between the body and the ring-member during rotation.

The relative rotation between the closure and the body, by action of the pins, causes flexing of the springs in the plane of the widths of the springs, and also radial flexure of the springs with relation to the body and reflector, for causing torsional movement of the springs to exert radial pressures by the springs upon the closure to aid in centering the closure on the body, and exert lateral pressure between the annular wall of the body and the annular Wall of the closure to aid in firmly securing the closure to the body and the reflector in the body and avoid vibration or rattling of the parts.

The present invention also provides means, by coaction between the closure and reflece tor, and between the reflector and the body, for firmly securing the reflector in the body,

and, by means of the cushion, sealing the space between the light transmitting plate and the reflector, for preventing the entrance of dust and moisture into said space.

The annular bead at the inner end of the annular wall of the body is arranged to coact with the rear edge of the annular wall of the closure to close the space between the rear end of the closure and the body.

A suitable electric lamp bulb may be provided in the rear end of the reflector, and may be suitably held in place or adjusted,-and have suitableelectrical connections therewith in any suitable or ,wellknown manner.

Having thus fully described my invention,
