JEWEL MOUNTING FOR LAMPS.
Application filed December 26, 1925. Serial No. 77,734.
My invention relates to means for simultaneously securing a lens to a lens-holder and securing the lens-holder to a perforated support, such as the casing of a lamp. Ve-
hicle lamps are often provided not only with a relatively large main lens, but also with a smaller lens, usually of a faceted or socalled jewel type, facing in another direction.
In mounting a small lens of this type, it has heretofore been customary to secure the lens permanently to a tubular holder or collar,
after which the collar is inserted in a suitable perforation in the casing or body of the lamp and is secured to this casing or body. In proceeding after this manner, the holder usually has a portion behind the lens spun to a contracted diameter after the lens has been inserted in the holder; and if the lenses vary in thickness, thick lenses are apt to be 2 cracked during the spinning operation while thin lenses are left loose and free to rattle in the holder. So also, the subsequent fastening of the holder to the lamp casing, when the lens is already mounted in the holder, must be carefully done to avoid breaking the lens. Moreover, a broken lens cannot readily be replaced.
My present invention aims to overcome these objections by providing an arrangement in which a single fastening or retaining member not only secures the lens-holder to the lamp casing but also retains the lens in the holder, in which this fastening member can readily be detached to permit a replacing of the lens if desired, and in which different parts of the fastening member automaticallycompensate for variations in the thickness of the lens and in the dimensions of the holder or thickness of the casing wall. Moreover, my invention provides a construction for this purpose in which the fastening member can be cheaply constructed and in which this member is securely latched to the holder without requiring any auxiliary fastening elements.
Illustrative of my invention, Fig. l is a plan view of a portion of a lamp casing, showing a lens of the jewel type mounted on it.
Fig. 2 is a vertical section through the same, taken centrally of the lens-along the line 22 of Fig. 1.
Fig. 3 is a vertical section'taken at right angles to Fig. 2 "and also central of the lens, the holder and the retaining member.
Fig. 4 is a vertical section taken along the line 4-4 of Fig. 1.
Fig. 5 is a horizontal section taken from the line 5-5 of Fig. 4 and looking upward.
Fig. 6 is a perspective view of the holder alone.
Fig. 7 is a central and vertical section through the retaining member alone, taken along the longitudinal medial plans of the arms of this member.
In employing my invention after the manner of the drawing for mounting a faceted lens 1 on a casing wall 2, I provide a holder having a tubular main portion 3 into which the lens may be slidably inserted from the inner end of the holder, and provide the wall 2 with a perforation 4 slidably fitting the exterior of this tubular holder portion. The outer end of the holder is spun into an annular head 5 of larger diameter than the said perforation and has its extreme end contracted to a bore smaller than the diameter of the lens, this end being desirably recurved so as to engage the lens at some distance radially inward of its periphery, as shown in Fig. 2.
To hold the lens against this recurved holder end and to secure the holder to the supporting wall 2, I provide a retaining member which desirably is made of a single piece of resilient metal. This retaining member comprises outer portions 6 adapted to engage the inner face of the wall 2, inner portions 7 adapted to engage the inner face of the lens and resiliently independent of the outer portions 6, and arms which connect the said inner and outer portions and which interlock with parts of the holder.
To provide for such interlocking, I form bayonet slots in the holder, each slot comprising an entrance portion 9 opening at the rear end of the holder and extending longitudinally of the holder, and a second portion 10 extending circumferentially of the holder from the inner end of the en- 1 trance slot portion 9. The circumferential slot portion has a part 10 of increased height spaced from the entrance slot 9 by a finger 11, both this taller slot part 10 and the entrance slot portion 9 being somewhat 105 wider than one of the arms 8 of the retain ing member.
The slots in the holder are preferably two in number and diametrically opposite, and the arms 8 of the retaining member being I10 also two in number and in alinement diametrically of this member, so that each of the resilient retaining member portions 6 and 7 is arcuate and extends nearly half way around the axis of this member. The
In using such a combination, the tubular portion 3 of the holder is inserted through the wall 20f the lamp casing or other support from the exterior thereof until stopped by the engagement of that wall with the larger diametered head 5. Then the lens is inserted into the holder from the inner end of the latter and the retaining member is attached to the holder from the inner end of the latter also. During this attaching, the arms 8 of the retaining member slide into the entrance slot portions until these arms pass the tips of the fingers 9, after which the retaining member is rotated with respect to the holder to bring the arms into alinement with the taller circumferential slot portions 10. Owing to the above described heights of the bowing of the resilient parts 6 and 7, these will respectively engage "the support wall 2 and the inner face of the lens before the arms 8 can clear the fingers or projections 11, but the resiliency of the parts 6 and 7 permits these to be flexed by forcibly pressing the retaining member towards the support wall 2 so as to allow the said rotating of the retaining member for alining its arm 8 with the taller slot portion 10*. As soon as the arms reach this latter position, the resiliency of the parts 6 and 7 flexes them back to a greater height, thereby seating each arm 8 alongside one of the fingers 11 as shown in Fig. 5.
lVhen thus attached, the resiliency of the outer arcuate portions 6 of the retaining member clamps the bead 5 of the holder against the supporting wall 2, while the inner arcuate portions 8 clamp the lens against the contracted forward end of the holder, and in each case the resiliency of these arcuate portions compensates for variations in the sizes or spacings of adjacent parts. Moreover, by pressing the retainin member toward the supporting wall unti its arms 8 clear the fingers 11 and then ro tating this member until these arms aline "with the entrance slot portions 9, the restruction and arrangement above described,
as many changes might obviously be made without departing either from the spirit of my invention or from the appended claims.
I claim as my invention: 1. The combination with a wall provided with a perforation, of a tubular holder extending through the perforation and having a portion engaging the outer face of the wall, a lens having a part thereof disposed within the holder, the holder having a stop formation engaging the lens to limit the outward movement of the lens, and a retaining member detachably secured to the holder and having resilient portions respectively engaging the inner faces ofthe lens and of the wall for holding the lens against the said stop formation and for holding the said holder portion against the wall.
2. The combination with a wall provided with a perforation, of a tubular holder extending through the perforation and having a peripheral bead enga ing the outer face of the wall, the holder having its forward end contracted, a lens inserted in the holder from the inner end thereof and having a portion engaging the contracted forward end of the holder, the holder having oppositely disposed perforations disposed beyond the inner face of the wall, and a retaining member. extending through the said perforations and having separate resilient portions respectively engaging the inner face of the lens and the inner face of the wall.
3. The combination with a wall provided with a perforation, of a tubular holder extending through the perforation and having a portion engaging the outer face of the wall, a lens havin a part thereof disposed within the holder, the holder havlng a stop formation engaging the lens to limit the outward movement of the lens, the holder having bayonet slots with entrances at the inner end of the holder, and a retaining member comprising two locking arms extending through the sald slots and two resilimember comprises a pair of concentric and resilient rings respectively disposed inside and outside the holder member, and a air of arms connecting the rings and exten ing respectively through the said bayonet slots. 5. A combination as per claim 1, in which the holder is provided at its rear ends with bayonet slots; and in which the retaining member comprises a pair of concentric an resilient rings respectively disposed inside and outside the holder member, and a air of arms connecting the rings and extending respectively through the said bayonet slots,
each ring having the portions between the toward the wall.
6. In a lamp, the combination with a casin wall having a perforation therein, of a tu ular holder having'its main portion slid ably inserted throu h the wall from the outside thereof, the 4 older having its outer two arms bowed out of the plane of the arms end provided with a peripheral bead of lar er diameter than its said main rtion amfenga ing the outer faceof the said wall, the said ead being contracted at its forward end to a bore smaller than that of the main holder ortion; a lens slidably inserted in the older from the other end of the holder and engaging the said contracted forward end of the bead; the said main rtion of the holder being provided with b yonet slots opening at the inner end of the holder and providing catch portions spaced inwardly from the said wall; and a retaining member comprising two arms extending respectively through the said catch portions of the bayonet slots and two resilient portions respectively engaging the inner face of the said wall and the inner face of the lens. 7
