LAMB.

Application filed August 29, 1925. Serial No. 53,436.

vide great rigidity and strength, and per` mit the use of a'cement and metal lath base material, which in turn forms a suitable surface on which blocks of tile of various attractive designs and shapes, may be properly mounted to forni the exterior surface of the lamp stem and base.

The aforesaid interior construction of the lamp is of an ingenious character and design, means being provided (and by using a comparatively small number of parts), for carrying the cement and metal lath shell on angle-iron upriglits or supports; and aremovable conduit is also provided which runs through the center of the lamp base and stein, for carrying` the necessary electric wires, or gas required for lighting purposes.

ln the drawings forming partof the present speciiication, I have shown a complete example, and a modification of the subject of the present invention, constructed according to the best mode so far devised for the purpose in hand.

ln the drawings, Figure 1 is a vertical side elevation, partly in section of the inveiition.

Figure 2 is an enlarged vertical and cene tral section of the lamp base, taken kon line 2-2 of Figure 3.

Figure 3 is a horizontal section of the lamp base on line13-3 of Figure 2.

Figure 1l; is an enlarged vertical section of the upper portion of the lamp stem, taken on line l-ii of Figure 5.

Figure 5 is a horizontal section through the stem of the lamp on line 5 5 of Figure 4.

Figure 6 is a horizontal section of a lamp stem and base, showing a modified form of same.

Figure 7 is a plan view of the -inetal capplate used with my invention.

Figure 8 is a front side elevation of Figure 7.

Figure 9 is a transverse sectional view of a metal base-plate, taken on line 9 9 of Figure 3. Y

ln the drawings the numeral 1 indicates the base ofthe lamp 2, saine being coinposed of a wooden blockB, through which Y is preferably a central perforation Ll; a metal base plate 5, having a number of outoutportions '6, 7 forming tongues which "project upwardly as shown in Figures 2 and Castors 10, 10 are mounted in the bottom of the wooden block 3 in the usual fashe ion as shown, for moving the lamp around the room readily.

The stem 11 of the lamp 2 is composed of preferably four angle- iron upriglits 8, 9, etc. and placed to form a tapered steiii of considerable height as shown Yin Figure 1 of the drawings.

The upriglits 8, 9 are riveted or bolted at points 12, 12, to the upstaiiding ends or metal tongues, 6, 7, of the aforesaid metal plate 5. At their upper ends the angle-iroii upriglits are fitted within a bent met-al capplate 13, which has a central perforation 14, and two depending iianges 15, 15 as shown in Figure l clearly. Two perforations `33, 33, are also made in the cap-plate 13 to permit lag-screws to pass therethrough for a purpose explainedhereinafter. The angleiroii uprights 8, 9, are attached at points 16, 16 to the flanges 15, 15 of the cap-plate 13, by bolts or rivets as desired.

Upon the cap-plate 13 is mounted a wooden block 17, having a central perforation 18 formed complementary to that of the caps plate 13, both of which provide a passage for the conduit 19 which passes through the vertical center of the lamp stem 11, to a point 20 at its base, Where said conduit makes preferably an abrupt turn as shown iii Figures 2 and 3, to the exterior of the lamp base 1, at the point 21.

At its upper end the conduit 19 connects with the short upper support 22 of the lamp asV shown. It is evident that the conduit 19, may be used eithervfor electric wires 23, 23, or if gas is used simply as a conduit for sam-e. It is also seen that the conduit 19 can be disjointed at point 20, and withdrawn verticallyand upwardly, through the perforations 14 and 18 of the cap-plate 13 and block 17 respectively; While the horizontal portion of the conduit 19 can be vwithdrawn at point 21 from the base of the lamp. This removable feature of the conduit is a very desirable one for repairing. the lamp, as is at once understood. The short upper support 22 of the lamp, is provided With a 'langed bottom 24C, usually for ornamental purposes, and said bottom flange can then be attached to the upper Wooden block 17 by means ot'- lag- screws 25, 25 as seen in the Figure l of the drawings.

The. lamp is provided with the usual `lamp shade 26, Within which are the usual electric lamp bulbs, or gas burners (not shown), according to the system of lighting used.

The lamp stem 1l, and base l, is further composed of an inner' layer, 27 of Cement mounted on metal lath, and said Cement layer forms a proper base material on Which is mounted a number of tiles 28, 29, preferably glazed, and ot various colors, and designs as shown in Figure l; said tiles being adapted to cover all the exterior faces of.

the lamp stem and base. It will be noted that the corner tiles at points 80, 3l, 32 are.

suitably Curved or roundedY for ornamental purposes, and that a variety of colors, shapes,

and designs may be used 'for these ,tiles7 all of which lends beauty and attractiveness to the lamp a Whole, and making the lamp a very desirable, use'lluhand ornamental feafture otl club rooms, hotel, and the like.

slight modification be made ot' a circularV cross-section such as illustrated by the Fig ure 6 ot the drawings, in which oase the terior tiles and Cement base must be arranged to suit the roundness of the curved outline, as is at once understood.V

I claim:-

n a lamp, a number of upstanding angleirons forming a support for the stem ofthe lamp, a inetal base-plate having a series of tip-.turned tongues formed thereon, eaeh'one ot which connects with oneoit the angleirons, for holding the latter inrigid relation to each other, a bent-metal cap-plate rigidly connecting the upper ends ot the angle-irons to each other, anenolosing shell of cement and tile, covering the lamp stem andbase, and a removable conduit passing through the .Stein and base of the. lamp.

ln testimony whereof I aiiix my signature.

CHARLES XV. MEEHAN.
