3 Claims.

This invention relates to an improvement in electric light fixtures, and, more particularly, to an improvement in the ornamental guard lantern style of light fixture.

The ornamental guard lantern style of fixture is frequently used for porch lights, gate-post lights, recreation room fixtures, and the like, in order that the incandescent electric light may be in keeping with present popular architectural styles. Such ornamental fixtures were generally moderately priced; however, as a result of this invention the manufacturing costs of such prior art fixtures were unnecessarily increased by employing screw clamps, relatively expensive guard cages,- and other elements which are now known to be unnecessary. However, the principal objection to prior guard lantern fixtures was the difficulty encountered when it became necessary to replace a burned-out light bulb or a broken globe or chimney; these fixtures are often placed in inconvenient locations where the disassembling and reassembling operations exceeded the mechanical capabilities of the ordinary householder and required a juggling of fixture parts which often resulted in dropping and breaking of the glass globe. Further, exposure of the fixture to weather frequently caused corrosion of the screw clamp, so that the fixture could be disassembled It is an object and advantage of this invention that a fixture made according to this invention is inexpensive and, though strong and secure when assembled, is readily manufactured and assembled in mass production with a minimum of-- operations. Because the fixture is so simple in construction, it is simply and easily taken apart and reassembled by the user. It is another object of this invention to provide a guard lantern in which the guard is an inexpensive, easily manufactured Wire cage. vention is to provide a light fixture avoiding the use of screws or clamps which become stuck when corroded by exposure to weather. Another advantage of this invention is that it is neat and attractive in appearance, and, in the preferred embodiment, the spot welds and split spring rings of the inexpensive cage are concealed from view.

Still another advantage of this invention is that the guard cage, in addition to its apparent function of protecting the lamp globe or chimney and serving as an ornament also serves as an essential structural element holding the fixture together.

.Further objects and advantages of this inven- A further object of this intion will be apparent from the following specification, claims, and drawings in which:

Fig. l is a vertical section through a fixture made according to this invention.

Fig. 2 is an isometric View of the wire cage illustrated in section in Fig. 1.

In the selected embodiment disclosed in the drawings, the fixture I0 is comprised of a top or hood portion 20 having a flattened apex 2| from which the fixture, in this'instance, i suspended by a suitable ornamental wall bracket I l. The fixture It is secured to the bracket l l by an ornamentally headed bolt I; which passes through an opening in the outstanding arm of the bracket l I, the ornamental spacing washer I 3 and thence through the flattened apex 2| and socket bracket 14 to a half-nut l5. Depending from the socket bracket I4 is the light socket l6 carrying the conventional incandescent light bulb IT, The wiring l8 for the socket i6 is led in through an opening 19 in the shank 23 of the hood 2!). Thus, in the preferred embodiment, the single bolt l2 and nut l 5 hold the fixture l0, supporting bracket H, and socket H3 in an assembly which, for all practical purposes, may be regarded as substantially permanent, since neither the fixture, socket nor bracket are likely to be removed or replaced in normal use. It is to be understood, of course, that the fixture ill may be supported by any other suitable means and the manner of supporting or wiring the socket 16 may be varied as desired without affecting the novel construction of the fixture I0. I

The hood 2B of the fixture I6 is a metal spinning contoured, in this instance, to provide a conical portion 22 depending from the flattened apex 2!, the portions 22 and 2| closing the integral cylindrical shank 23. shank 23 is a lower outwardly flaring skirt por tion 24, the outer edge of which is spun in to pro vide an internally-opening annular groove or recess 25 in which the upper split spring ring 4| of the guard cage 40 is received.

The base 3!! of the fixture Ill is' comprised of anornamentally contoured shank portion 33 having an upper outwardly flaring skirt portion 34, the

Thebulb H is easily inserted or removed through the open and the lower split spring ring 42, the pair of in round by the groove. the ring is under compression or merely holds its normal set when received in its corresponding groove, the diameter of the'ring must be such that the ring must be compressed (b pressing together the guard wires adjacent the split) in order to remove the ring from the groove.

25 and are exteriorly opening instead of interiorly opening, then the guard wires should be spot-welded to the outside of the ring received in the exteriorly opening groove. An advantage of 5 providing interiorly opening grooves .in which the 10 its corresponding groove when the ring is held Regardless of whether To complete the fixture, a glass globe or chime ney is provided. The globe 59 when shown in the drawings has a cylindrical body portion 5! which may obviously be molded to provide annular corrugations or otherwise contoured to provide simulated lenses or other surface ornamentations. The upper and lower ends of the globe terminate in inset portions to provide

upper andlower shoulders

52 and 53 which at least approximately mate with the shoulders provided by the junction of the upper shank 23 and skirt 2:; and the lower shank 33 and skirt 3%, so that the shouldered globe 50 is retained in the fixture by the shoulders provided in the base and hood.

The lower split ring 42 is then compressed To disassemble the fixture to permit a broken globe to to be replaced, the cage is simple comorAZ can bottom of the base 313 in the embodiment shown,

though innfodels having a closed base, it is sim- "pie to disassemble and then reassemble the fiX- ture in order to replace a burned-out bulb.

The operations, for manufacturing the fixture it are obviously simple and inexpensive. The

' hood 28 and base 39 may be readily formed from 'sheet'metal'or tubing by spinning or stamping.

The cage it-is assembled and spot-welded together on a jig. In this connection, it is to be noted that, in the preferred embodiment disclosed,'the guard wires 43 are spot-welded to the inside of the split rings 4! and Q2 so that the ,guard wires do not interfere with the reception r of the spring rings 6! and 42 in their respec-

split rings are received is that the spot-welded junction between the guard wires and the split rings, as well as the split in the rings, is concealed. It should also be noted that an advantage the fixture. It should also be apparent that this fixture is not limited to the use of a shouldered globe; instead of providing a shoulder in the ends of the globe, the shanks of thebase and hood may ,be externally shouldered to receive the ends of a straight-walled cylindrical globe, for example.

From the foregoing, it should be apparent that this invention is not limited to the specific emvaried as desired'within the scope of the following claims.

What is claimed is: I
