LAMP CATCH.

Application ledseptember 30, 1925. Serial No. 59,659.

The invention relates to vehicle lamps and has more particular reference to the means for holding the lens ring in closed position and the invention consists in the novel construction of such retaining means as hereinafter rset forth. v

.In the drawings:

Figure 1 isa longitudinal section through a portion of a lamp housing and ring showing my improved catch applied thereto.

Figure 2 is a perspective view of one of the loops.

Figure 3 is a bottom plan view of a portion of Figure 1.

Avis a -lamp housing of any suitable construction which is provided with a reinforcement B to which the securing shank C is attached. D is a lens holding ring containing the lens D having suitable engagement with the forward edge of the housing A, such as the shoulder bearing E, forwardly extending flange F and inwardly extending flange G on the housing, with which parts the ring is telescopically engaged. His a sealing gasket which is arranged between the flange G formed on the reector G and the lens D forming a yielding bearing for the latter, the flange G having a bearing on the flange Gr formed on the housing.

The lens ring is preferably provided with a yieldable hinge engagement with the housing which, as shown, comprises a. loop spring member I having at one end a hook I for engaging an aperture in the flange G. The opposite end Iz'of this spring passes through a slotted aperture J in the'member F and engages a slotted bearing K in the ring member,- while the intermediate portion of the spring has a bearing on a portion of the housing whereby outward movement of the loop is prevented. Thus, when the ring is angularly inclined, the slotted bearing K may be engaged with the projecting end I2 of the spring which latter will yield as the lens D enga-ges the sealing ring H.

, To retain the opposite side .of the lens ring I have provided a loop spring L having one end anchored to the housing and its opposite end extending outward through a slot therein and pivotally connected t0 a hook member M. This hook member is engageable with an aperture in the ring D and because of the resiliency of the loop, is yieldably adjustable. Thus the rin D is free to seat itself against the gasket and ing having a slot and a lens ring engagen able with the casing, of means for yieldably retaining said lens ring in position on the casing, said means including a loop spring having one end detachably anchored to the casing and its other end extending through the slot in the casing for engagement with the said lens ring, said loop 'spring being provided With means for `bracing the end extendingl through the slot against movement in any direction except a direction parallel to the axis of the said lamp. y, i
