AUTOMOBILE LA MP Filed Dec. 9, 1935 'INVENTOR BENJAMIN PwrnwA/v Patented Feb. 8, 1938 UNITED STATES PATENT OFFICE AUTOMOBILE LAMP Application December 9, 1935, Serial No. 53,501
3 Claims.
This invention relates to new and useful improvements in lamps, especially tail and stop lamps for automobiles.
In many of the lamps of this type heretofore proposed it is necessary to use'special tools such as wrenches, pliers, screw drivers, or the like, in order to disassemble and assemble the lamp to replace a lamp bulb.
7 It is an object of the present invention to provide a lamp in which use of tools may in large part be dispensed with.
To this end the present invention provides a lens which may be merely snapped into or out of place without the use of tools of any kind.
iii In many of the previously proposed lamps several parts (e. g. bezel ring, screws, nuts, washers, lens) had to be removed before a lamp bulb could be replaced, with the attendant and considerable likelihood that certain parts would be lost, es-
20 pecially at night when bulb changes are usually effected.
It is a further object of the present invention to provide a lamp wherein there is little danger of losing important parts when the bulb is changed.
A feature resulting from the attainment of this object is the provision of a lamp wherein only a single unit need be removed from the casing when a change or repair is made, and since this unit is a large one, there is no danger of losing it.
It is a highly important object of the present invention to provide a lamp with a thoroughly enclosed light chamber so that dust, dirt, moisture, and rain cannot adversely enter the same and impair the etficiency of the lamp, as can occur in those lamps having a split casing or some similar structure.
In meeting this object the present invention provides a lamp wherein the casing is not split and the lamp is thoroughly dust and moisture proof at all times while in use, even though gaskets and other like conventional sealing means are not used. A supplementary feature is the provision of resilient means adapted to draw a flange on the lens snugly against the casing so that undesirable matter cannot enter the casing.
Another advantageous feature of the present invention is the provision of a lamp with a lens and holding ring, in which the lens alone may 50 be replaced if broken without also replacing the holding ring.
Other objects, features, and advantages will be apparent or described hereinafter.

Fig. 9A is a fragmentary section of the lens ring.
Fig. 10 is a fragmentary detail of a modified form of lens unit.
Fig. 11 is a modified form of casing for use with the preferred form of lens unit.
Referring now in detail to the drawing which shows the present preferred embodiments of the invention, and to Figs. 1-4 first, the lamp comprises a casing I4 of cup like or any other desired shape, which may be secured to a license plate bracket or the like by any of the now well known and conventional securing means. Also, in the conventional manner the casing supports a socket l5 for a lamp bulb l6 within a light chamber ll. A license plate illuminating opening l8 may be provided on any side of the casing and enclosed with a glass l9 and gasket 20 held in place by screws 2|.
According to the present invention, the casing I4 is at its front provided with an inwardly projecting flange 22 defining a light passage opening 23. The flange 22 is provided with front,
inner, and back walls 24, 25, and 26 respectively '5 adapted to receive and hold a lens unit 21.
The lens unit 21 in its present preferred form comprises a metal ring 28 having a main channelled flange 29 adapted to receive a peripheral flange 30 of a red or other suitably colored lens 3| (Fig. 4). The channelled flange 29 is provided with a curled in top edge 32, by spinning or other deforming, to hold the lens in the metal ring, as may be seen best in Figs. 1-4, inclusive. The flange 29 is provided with a. rear wall 33 adapted to flt snugly against the front wall 24' of the flange 22 on the casing [4.
A thimble 34, projecting rearwardly of the flange 28 is provided on the lens unit 21 and preferably integral with the flange 29 of a diameter snugly fitting the opening 23 and adapted to project therethrough. A bevel 35 may be provided to facilitate inserting the lens unit into the opening of the casing.
Projections 3'! provided on the thimble 34 to form a connection 35 capable of holding the lens unit 2'! to the casing i l. Preferably these projections are struck up from the. thimble so that they will be resilient and pressed inwardly oi the thimble by the inner wall 25, and are spaced from the rear wall 33 of the channelled flange 29 just enough to snap in back of the wall 26 of the casing flange 22 and thereby draw the rear wall of the lens unit securely against the front wall 26 of the casing flange, to make a dust and moisture proof connection at this point and to securely hold the lens unit 2!? to the casing i l.
To make this assembly of the lens unit- 2? to the casing, it is merely necessary to press the thimble 34 of the lens unit 2? into the opening 23 of the lamp casing No special tools are required. Similarly, when it is desired to remove the lens unit to replace a burnt out bulb, it is merely necessary to grasp the exposed channelled flange 29 with ones fingers and pull the lens unit from the casing. Or, if preferred, any kind of a prying tool may be inserted between the walls 24 and 33 to effect the disconnection, although such tools are really not required.
. For economy in manufacturing cost the thimble 34 may be formed with a continuous annular projection rather than with the separate projections 3'! shown. However, this does not give very much resiliency to the snap connection and makes it harder to remove the lens unit with ones fingers.
A preferred form of snap connection 362) is shown in Fig. 3 in which the thimble 3-1 is provided with a plurality of short longitudinal slots v 33 forming a plurality of resilient fingers 39, one
or more of which may be provided with a projection 31. This form is easy to snap into and out of place in the lamp casing l4, yet holds the lens unit in place very eifectively.
The metal ring 28 may be given various finishes, different than the exterior of the casing 14, thereby improving the general appearance and esthetic appeal of the lamp.
The snap connections 36 and 36b may be used equally well to snap into a female flange 22a in a modified casing Ma, as will be quickly apparent by viewing Fig. 11.
Figs. through show some forms of the present invention basically similar to the forms just described in detail, differing mainly in the provision of a split metal ring 28a whereby it is possible to replace broken lens Si or change a lens of one color to that of another color without replacing a complete lens unit. With the split ring form of the present invention, as with the forms already described, it is not necessary to use tools of any kind when replacing a lamp bulb, or the like. The casing M need not be changed in any way.
Figs. 5, 6, and '7 show a lens unit Zia, with a snap connection 360 of a modified form comprising a split metal ring 280, with flange 29a having a preformed channel 40 adapted to receive the peripheral flange of the lens 3! and to thoroughly hold the same when the ring is closed in.
A rearwardly projecting thimble 35a with a peripheral groove 4| is provided on the ring. This thimble, because of a split 42, is resilient and may be pushed through the opening 23, the wall 25 serving to squeeze in the thimble until the groove ti aligns with the flange 22 where upon the groove Ell grips the end wall and holds the unit in place and draws the flange 2% thereof against the front wall 25 of the casing.
The advantages of the split ring structure may, if desired, be embodied in the structures disclosed in Figs. 1-4 and described in detail by providing a split in the metal ring 28 similar to the split 42 disclosed in the modified construction of Figs. 5 and 6.
A modifled snap connection 3 5d may be provided on the lens unit 21a by providing longitudinal slots 53 as disclosed in Fig. 8.
If it is desired to dispense with the peripheral groove ii, a snap connection 35c may be provided on a metal ring 281) by having a thimble B ll) of smaller diameter as it approaches the flange 29%; as disclosed in Fig. 10.
Other variations and modifications may be made within the scope of this invention, and portions of the improvements may be used without others. I
Having thus described the invention, what is claimed as new is:
l. A lamp, comprising in combination a casing; an inwardly projecting flange on said casing de fining a light opening; a lens; a metal ring havmg a forwardly projecting channelled flange for holding said lens and having a rearwardly projecting thimble insertable in said light opening; and projections on said thimble spaced circumferentially thereof, cooperable directly with said casing flange to draw the channelled flange against the latter to thereby lock the casing flange between the channelled flange and the projections.
2. A lamp, comprising in combination a casing; an inwardly projecting flange on said casing deflning a light opening; a lens; a metal ring having a forwardly projecting and continuous channelled flange for alone holding said lens and having a rearwardly projecting thimble insertable in said light opening; and portions on said thimble projecting outwardly a distance greater than the diameter of said light opening, adapted to be snapped under said casing flange when the thinible is inserted in the light opening to thereby lock the casing flange beween the channelled flange and the outwardly projecting portions.
, A lamp, comprising in combination a casing; an inwardly projecting flange on said casing deflnin a light opening; a lens; a metal ring having a forwardly projecting and continuous channelled flange for alone holding said lens and having a rearwardly projecting thirnble with rearwardly extending slots therein spaced circumferentially thereof; and portions on said thimble between said slots projecting outwardly a distance greater than the diameter of said light opening, adapted to be snapped under said casing flange when the thimble is inserted in the light opening to thereby lock the casing flange between the channelled flange and the outwardly projecting portions.
