No. 858,369 8 Claims. (Cl. 240-112) This invention relates to a novel lamp for providing illumination, and more particularly to a lamp of unique ornamental appearance which is so constructed that all light rays emitted therefrom are reflected.

Another object of the invention is to provide a lamp structure wherein the light source is completely concealed.

Still another object of the invention is toprovide a lamp composed of sections capable of being readily separated for replacement of the light source.

Another object of the invention is to provide a lamp having a plurality of sides each provided with an opening through which the reflected light rays from the concealed light source of the lamp are emitted.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, illustrating a presently preferred embodiment thereof, and wherein:

FIGURE 1 is a side elevational view of the lamp;

FIGURE 2 is an enlarged fragmentary side elevational view of a portion of the lamp;

FIGURE 3 is a horizontal sectional view through the lamp, taken substantially along a plane as indicated by the lines 33 of FIGURES 2 and 4;

FIGURE 4 is a fragmentary vertical sectional view taken substantially along a plane as indicated by the lines 44 of FIGURES 3 and 5;

FIGURE 5 is a top plan view of the intermediate section of the lamp, with the top section removed, and

FIGURE 6 is a horizontal sectional view taken substantially along a plane as indicated by the line 66 of FIGURE 4, partly broken away.

Referring more specifically to the drawings, the ornamental lamp in its entirety is designated generally 8 and is composed of a lower section 9, an intermediate section 10 and an upper section 11. The lamp 8 is pentagon shaped, as viewed from above, but could have more or less than five sides.

The bottom section 9 includes a substantially flat five sided top wall 12 which is supported by five corresponding depending walls 13 which are suitably secured to or formed integral with the five straight edges of the top wall 12 and which extend downwardly and inwardly therefrom. Said depending walls 13 taper in width toward their lower ends and are joined to one another along their downwardly converging side edges, so that the five walls 13 form an inverted truncated pyramid. A flat rigid plate 1-4 has the central portion of one face thereof suitably secured, as by welding, as seen at 15, to the truncated end of said inverted pyramid portion. The plate 14 forms the base for the lamp and is likewise preferably pentagon shaped and somewhat smaller than the top plate 12. A plurality, preferably five pins 16 are secured in and extend upwardly from the wall 12 and a spacing sleeve 17 is mounted on each pin 16. The pins 16 are spaced from the corners and edges of the plate 12.

The intermediate lamp section 10 includes a pentagon shaped substantially flat bottom plate 18 and a corresponding top plate '19. The plate 18 has a short depending wall which is likewise pentagon shaped and Patented July 25, 19 1 ICC extends downwardly from the five edge portions thereof, and the top plate 19 has an upstanding wall 21, corresponding to the wall 20. The plates 18 and 19 are each provided with a central opening 22 and pin receiving openings 23. The pin receiving openings 23 of the bottom plate 18 are positioned to receive the upper ends of the pins 16 when the plate 18 is located directly above and in alignment with the plate 12. The intermediate section 10 is connected to the bottom section 9 by the pins 16 and the intermediate section is supported by its bottom plate 18 resting on the spacing sleeves 17. When thus disposed, the wall 20 extends between the edges of the plates '12 and 18. The plates 18 and 19 are also provided with a plurality of vent openings 24, which are spaced from the

openings

22 and 23 thereof and which are preferably somewhat smaller than the central opening 22, as best seen in FIGURE 5.

The intermediate section 10 includes an inner bottom plate 25 and an inner top plate 26. The inner bottom plate 25 has a central portion spaced substantially from the plane of the plate 18 which is provided with an opening 27 which aligns with the opening 22. The

plates

25 and 26 are also pentagon shaped and the marginal portion 28 of the plate 25 rests upon and is secured to the marginal portion of the plate 18, in any suitable manner, as by welding, as seen at 15 in FIGURE 4. The plate 25 has five portions 29 which slope downwardly and outwardly from the central opening 27 of said-plate to its marginal portion 28, and which sloping portions 29 coincide with the five straight edge portions of the plates 18 and 25. The plate 26 corresponds with the plate 25 except that it is inverted so that the portions 29 thereof slope downwardly and inwardly from the marginal portion 28 to the central opening 27, and the inner top plate 26 is secured to the top plate 19 in the same manner that the plate 25 is secured to the plate 18.

The intermediate lamp section 10 includes five corresponding vertical partition walls 30 which are equally spaced from one another, as seen in FIGURE 3, and which have downwardly and inwardly inclined upper edges secured to the inner top wall 26 and upwardly and inwardly inclined bottom edges which are secured to the inner bottom wall 25. The inner edges of the walls 30 terminate adjacent the openings 27, as seen in FIGURES 3 and 4. Each of the walls 30 extends toward one of the five corners of the pentagon shaped lamp, as seen in FIGURE 3, from its inner edge, and each of said walls or partitions is preferably formed of two plies having outer portions 31 which are flared away from one another and inner portions 32 which are secured together in abutting engagement.

The intermediate section 10 includes five corresponding upright corner posts 33 of angular cross section, as seen in FIGURE 3, corresponding to the angles formed by the adjacent sides of the lamp. The lower ends of the corner posts 33 are secured, as by welding, to the corners of the wall 20 and the upper ends of said corner posts are similarly secured to the corners of the wall 21. The flared outer edges of the ply portions 31 of each wall 30 are secured to the vertical side edges of the corner post 33 with which said wall 30 aligns, as clearly illustrated in FIGURE 3.

The intermediate section 10 also includes five upright opaque shields 34 each of which is disposed between two adjacent partition walls 30 and spaced therefrom. Each shield 34 has pins or studs 35 projecting from its upper and lower ends. The upwardly extending studs 35 engage in and are secured to the wall 26 and the downwardly extending studs 35 engage in and are secured to the wall 25 for mounting the shields 34 between and spaced from

said walls

25 and 26 and also between and spaced from the partition walls 30, as seen in FIGURES 3 and 4. The shields 34 are spaced equal distances from the center openings 27 and are located between and spaced from the center openings 27 and the openings 36 of the five sides of the intermediate lamp section 10. Each of said openings 86 is formed by complementary portions of the walls 20 and 21 and two adjacent corner posts 33, as best illustrated in FIG- URE 2.

A conventional double lamp bulb socket 37 is mounted between and secured to the inner edges of the walls 30 and may be secured to the inner edges of said walls by a press fit engagement or by additional solder connections 15. The socket 37 is disposed between and spaced from the

walls

25 and 26. Lamp bulbs 38 are mounted in and project from the opposite upper and lower sides of the socket 37 and are disposed between said socket and the openings 27. The openings 27 are of a larger diameter than the lamp bulbs 38 and are of the same diameter as the openings 22, so that the lamp bulbs 38 can be removed and replaced through the

openings

22 and 27 when the lamp sections are disconnected, as will hereinafter be described. The inner edges of the partition walls 30 combine with inner ends of the sloping wall portions 29 to form inner openings between the shields 34 and the light bulbs 38.

The upper section 11 comprises a bottom Wall 39, corresponding to the wall 12 and five upwardly and inwardly converging walls 40, corresponding to the walls 13. The walls 40 form a truncated pyramid, as seen in FIGURE 1. The wall 39 is provided with pins 16, arranged in the same manner as the pins 16 of the wall 12, and which last mentioned pins extend downwardly from and are secured to said wall 39 and have spacing sleeves 17 mounted thereon and secured to the pins, beneath the wall 39. Said last mentioned pins 16 engage detachably in the openings 23 of the wall 19 and the last mentioned sleeves 17 rest on the wall 19 for detachably connecting the top section 11 to the intermediate section and for mounting said top section thereon. The wall 21 coincides with the edge portions of the wall 39, in the same manner that the wall coincides with the edge portions of the wall 12.

Electric current can be supplied to the lamp socket 37 in any desired manner, as by an electric cord 41 which can extend into the base section 9 through an opening 42 in one of the walls 13 and thence upwardly through an opening 43 in the wall 12 and thence through the opening 22 in the wall 18 and opening 27 of wall 25 to the socket 37. The cord 41 can be positioned to extend along the inner edge of one of the walls 30.

It will be readily apparent that light rays from the light bulbs 38 will pass outwardly around the opaque shields 34 between the side edges thereof and the walls and between the top and bottom edges thereof and the

walls

26 and 25. The

walls

30, 25 and 26 are formed of a light reflecting material so that the light rays from the light bulbs 38 will be reflected from said walls and outwardly through the openings 36. Thus, none of the light rays will be emitted directly from the lamp 8 and all emitted light rays will be reflected. Furthermore, the light bulbs 38 are completely concealed within the intermediate section 10, as clearly illustrated in FIG- URES l and 2, so that the light source of the lamp is not visible.

The upper light bulb 38 can be replaced by merely lifting off the upper section 11, after which the upper light bulb is removed and replaced through the opening 22 of the wall 19 and the opening 27 of wall 26. The lower light bulb 38 is removed and replaced by lifting the intermediate and top section all of the base section 9 so that said bulb can be removed and replaced through the opening 22 in wall 18 and opening 27 of wall 25. Sufiicient slack in the electric cord 39 can be retained in the base section 9 for this purpose.

Various modifications and changes are contemplated and may be resorted to, without departing from the function or scope of the invention as hereinafter defined by the appended claims.
