JOSEPH W. TURNER, OF DES MOINES, IOWA.

ELEGTROLIER.

Specification of Letters Patent.

Patented Sept. 27, 1910.

Application filed August 4, 1909. Serial No. 511,228.

To all whom it may concern:

Be it known that l, Josnrn WV. TURNER, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Electrolier, of which the following is a specification.

The object of my invention is to provide a main supporting pole and lateral arms of simple and inexpensive construction that may be readily and easily manufactured by a casting process, and in which the arms are detachable from the central pole without the use of bolts, screws or similar fastening devices.

A further object is to provide a device of this class which may be used with any desired number of lateral arms, and the arm supports on the main pole that are not used may be covered and concealed and the openings therein protected so that the pole will present a finished and ornamental appearance regardless of the number of arms attached thereto.

My invention consists in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows a vertical, central, sectional view of an electrolier embodying my invention. Fig. 2 shows a perspective view of the top of the post portion. Fig. 3 shows an enlarged, horizontal, sectional view through the top of the post portion and through two of the lateral arms and two of the protecting and finishing plates applied to the post. Fig. 4 shows a sectional view illustrating the upper portion of the post and the lower portion of the upper lamp supporting device. Fig. 5 shows an en larged, detail end view of the inner end of one of the lateral arms, and Fig. 6 shows a detail, vertical, sectional view of the top of the post and one of the lateral arms applied thereto.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate the base portion of the post which is preferably formed hollow and of cast metal.

I 11 indicates the upper portion of the post which is also formed hollow and of cast metal, and which has a rectangular opening at its upper end. The upper portion of the post is made of rectangular shape to provide four flat faces 12 arranged vertically. On each of these faces, I have formed a lug 13 to be used in connecting the lateral arms to the main post. Each of these lugs is tapered from its lower toward its upper end, and the sides of the lugs are beveled or inclined inwardly toward each other so that the lug is of less thickness at its inner edge adjacent to the flat face 12 than at its outer end. The top of each lug is spaced apart below the top of the flat surface 12 and is preferably inclined upwardly toward the outer end of the lug, as clearly shown in Fig. 6. At the center of the lug there is an opening let that extends through the lug into the interior of the post.

I have provided a lamp bracket for the top of the post, which lamp bracket may be made of cast metal and comprises a body portion 15 having a rectangular lower end 16 designed to fit into the rectangular upper end of the post. It is also provided with a flange 17 to overlap the top of the post. A globe 18 is fitted to said bracket in the ordinary way and a pipe 19 is screwed into the body portion of the bracket, the said pipe being open at both ends so that electric wires may be readily passed through it, and the upper portion of said pipe being provided with a lamp socket 20 of the ordinary kind, as shown in Fig. l. I have also provided a number of lateral arms for the device, each of which is designed to be made of cast metal and comprises a hollow body portion 21 having at its inner end two inclined side portions 22, and a top portion 23 so arranged as to be readily and easily placed on the lugs 13 from the top and then moved downwardly so that said side pieces 22 will accurately lit-against the top of said lug. The said top 23 has its under surface inclined downwardly toward the end of the arm 21, as shown in Fig. 6, and the said sides 22 have their inner surfaces inclined toward each other and toward the end of the arm, as clearly shown in Fig. 3, to thereby fit against the sides of the said lug 13.

At the outer end of the arm 21 is a threaded pipe at seated in the arm 21 and extended downwardly and having a lamp bracket 25 attached thereto. The lower end of said pipe is designed to receive a lamp socket 26, as shown in Fig. 1. In many instances, it is desired to use the electroliersfor less than four lateral arms, and assuming that it is desired to have only two of the lateral arms extended in opposite directions, I have provided two detachable plates 27 each of which is shaped at its inner end exactly like the inner end of one of the lateral arms, as shown in Figs. 3 and 5, and the outer surface of said plate is arranged substantially flat and may be ornamented by any suitable design such, for instance, as that shown at 28 in Fig. 3.

In practical use, it is only necessary to provide one set of patterns for making electroliers having any desired number of lateral arms. I then proceed to erect the base portion of the electrolier in the ordinary manner and then I place thereon the desired number of lateral arms. This is done by simply placing said arms in proper position relative to the lugs 13, and then forcing them downwardly until they firmly engage with said lugs. Then the lugs that are not provided with arms are covered by means of the detachable plates 27 which are placed thereon in the same way as the arms. By means of this detachable feature of the arms, it is obvious that said arms may be made to extend in any desired direction from the post, provided there is less than the full number of arms for which the post is constructed, and if any of the lugs 13 are not provided with arms, the openings therein may be c mpletely covered to make them water tight and at the same time the post may be given a finished and ornamental appearance by simply applying the plates 27 All the various parts of the post may obviously be assembled and firmly held in position without the use of bolts, screws, and the like.

I claim as my invention:

1. In a device of the class described, the combination of a post having a number of openings near its upper end, an arm detachably connected with the post to cover one of said openings, and a plate detachably connected with the post to cover another of said openings.

2. In a device of the class described, the combination of a. post having a number of openings near its upper end, an arm detach ably connected with the post to cover one of said openings, and a plate detachably connected with the post to cover another of said openings, said arm and plate being interchangeable and capable of being secured over any of said openings.

3. In a device of the class described, the combination of a hollow post body portion having at its upper end a number of lugs at the sides thereof, said lugs being widest at their lower ends, and the sides thereof being tapered on divergent lines away from the post, each of said lugs being provided with an opening extending through the lug and through the post, an arm designed to support a lamp at its outer end and having its inner end provided with side pieces spaced apart and tapered to fit the sides of said lug, and a plate having its inner surface designed to fit one of said lugs, and its outer surface substantially fiat, for the purposes stated.

4:. In a device of the class described, the combination of a post body having a fiat face on one side of its upper end, a lug at the central portion of said fiat face, said lug being tapered toward its upper end, and the sides of said lug being arranged on divergent lines away from the post, and said lug being provided with an opening extending through it to the interior of the post, and a lateral arm having means at its outer end for supporting a lamp and having, at its inner end, sides spaced apart from each other and inclined toward each other at their upper ends, said sides being also beveled to fit against the sides of said lug.

5. In a device of the class described, the combination of a post body having a fiat face on one side of its upper end, a lug at the central portion of said fiat face, said lug being tapered toward its upper end, and the sides of said lug being arranged on divergent lines away from the post, and said lug being provided with an opening extending through it to the interior of the post, and a lateral arm having means at its outer end for supporting a lamp and having, at its inner end, sides spaced apart from each other and inclined toward each other at their upper ends, said sides being also beveled to fit against the sides of said lug, the top of said lug and the top portion of said sides being both inclined outwardly and upwardly away from the post, for the purposes stated.

6. A device of the class described, comprising a post body portion made of cast metal and formed hollow and having a rectangular opening at its upper end, a lamp support fitted into the rectangular upper end of the post, said upper end of the post being provided with a number of flat faces, a lug formed on each of said fiat faces having its upper end spaced below the upper portion of said flat face and its sides tapered toward the upper end, and said sides being also arranged on divergent lines away from the post, said lug being also provided with an opening extending through it into the interior of the post, a number of lateral arms, each being provided With a lamp supporting means at its outer end, and each having at its inner end, two sides spaced apart, and a top portion above said sides designed to fit against the sides and top of one of said lugs, and a plate having its inner surface shaped similar to that of said arm and fitted to one of the lugs on the post, the

outer surface of said plate being substantially flat.
