Application filed Junel 6, 1914. Serial No. 843,538.

1'0 atl whom it may concern Be it known that I, ALFRED C. ABRAMsoN, a citizen of the United States, residing at Robkford, in the county of Winnebago and State of illinois, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

This invention relates to lamps adapted to be equipped with shades, more particularly to those used for ornamental lighting.

My invention aims primarily to provide an improved construction of lamp and shade, for producing a pleasing and ornamental design, and for permitting the lamp and shade to be manufactured at a low cost.

Another object is to provide a lamp with means for receiving different types of illuminating means, such as a candle, an oil light, or an electric globe, interchangeably, according to the lighting facilities aty hand and the use to which the lamp is to be put.

I also provide in my improved lamp, a construction for retaining a candle-socket, oil-receptacle, or electric light socket in position whereby either' of said illuminatingmember carrying-means is covered from view.; for it is desirable in lcarrying out a pleasing design of lam and pedestal, to inclose such metallic par s from view.

Another object of my invention is to provide a shade of novel construction and means for attachingthe shade to the lamp in such a manner that the shade will be held fixed in position, yet will be easily detachable; and further, to provide attaching means for the shade such that the shade may be inverted to permit the lamp and shade to occupy but a minimum space when being transported or shipped.

The nature of my invention, its mode of use, and the advantages inhering therein will be readily understood from a consideration of the accompanying drawings wherein I have illustrated preferred and modified mechanical embodiments of the invention, and wherein- Figure 1 is a vertical sectional view centrally through the top portion of a lamp holder of the preferred embodiment of the invention, showing an electric globe as the illuminating means. Fig. 2 is a vertical sectional viiew through a lamp and shade embodying my improvements, showing a modified form of means for holding the shade in position. Fig. 3 is a view partly in'elevation and section of the lamp and shade,

showing a candle as the illuminating means. Fig. 4 is an elevation of the holder and shade, showing the shade reversed adapted -for shipping. Fig. 5 is a perspective view -lamp body being shown in section; and Fig.

8 is a perspective of the upper end of the lamp receptacle. t

Referring to the drawings, reference numeral 9 designates a lamp base or pedestal preferably of wood turned to an ornamental design. The upper end of the basa is enlarged `at 11 and formed with a circular axially alined socket 12 open at its top end, providing a receptacle for illuminating means, and al central bore 13 extends throughout the Abase to permit electric wires or gas-pipe to enter the socket 1l. The upper end of the receptacle portion 11. is provided with an annular raised Piange 14E, Figs. 1 and 8, which has formed therein a plurality .of vertically disposed slots 15 open at theirupper ends for the reception of shade supporting-means, and a vertically disposed slot 16 for the reception of an electric-socket switch-chain. A

A lamp-shade frame is constructed of upper and lower hoop-

menibers

17 and 18 re spectively, connected by a plurality of relatively narrow-strip metallic supports 19, each xedly connected to the hoop-members without the use of auxiliary attaching means,A as clearly shown in Figs. 2 and 5. The'lower portions of said supporting-members are extended inwardly from the lower hoop-member and terminated short of the center thereof to leave an open center, these inwardly extended members providing shade-supporting means 21. Each supporting-member 21 is adapted to be received in a slot-.15 whereby the shade is mounted centrally relatively to the receptacle llyin a positive manner, but free to be detached. The shader-frame will, of course, be provided with an appropriate covering preferably fabric, attached to the hoop-members 17 and means which may be ot diilierent torres. l;

have illustrated a preferred form in Fig. l, in. which an electric-socket 23 has a threaded shank il received screw-threaded into the apertured plate 22, the switch-chain of said electric-socket extending through the slot 16. Suitable wiring is provided for the electric-socket. i cover' or cap 26 is shaped to i-nclose the top of the socket 1l and the electric-socket 23. rThe cap is provided with a central aperture 27 for the reception of the globe-receiving end of the electricsocket and with an annular groove 28 in its lower face adaptedto fittingly receive the annular flange l5. It will be manifest, nith the shade mounted upon the receptacle ll, that when the cover 26 is moved downwardly its lower face will impinge the top of the supports 2l, and that by screwing the electric-globe 28 into the socket 23, the globe will engage the cover at 29 and force the saine downwardly upon the supports 2l, thus .locking the shade in position. it is necessary that the electric-socket 23 be properly adjusted vertically so that when globe is screwed thereinto, the globe will have contacted the terminal of the electricsocket at approximately the same time the cover 26 is moved to its support-holding position. rlhe above described means 'for holding the shade in set position is the preferred form where electric illuminating means is used.

In ligs. 2 and 7 l have illustrated a mo lied foi-in oi means ceperating,` with the illuminating-means for holding the shade in position. Upon inspection of these nresit will be observed that the top receptacle ll is devoid. ot the annular il 14 shown in Fig. l, that the electric l? socket 22) is screwed into a. plate as the 'former case, but that the covcrli i'ixedly attached to the electric-soc through the agency oi brackets and under face of the cover is provided with ccsses 33, clearly shown in Fig. 7, for tl reception the supporting-members 2i. Jy this construction the cover, electric-socket, and globe may be screwed as a unit into position with the base, to hold the sli supports in a locked set position. .tt be evident though, that the electric wires connected to the socket are loose at the bottoni end of the pedestal, as shown in Fig. 2,

' they will be twisted by screwing the electricsocket to position; and when the 'wires are fixed at said opposite end, as to a terminal at the base of the pedestal, the screw-connection between the electricssoc'ket shank and the plate 22 must be comparatively short. Other forms of illuminating-member carrying-means may be used in place ot that for carying an electric-globe, this beine de: sira'ol Afor obvious reasons. in Fig.

rasata/i Lof' this nature, it is manifestly desirable that the several parts be as compact as possible. By detaching the shade fastening-means of any or the above described structures, the shade may be inverted as shown in Fig. d, and the fastening-means again attached to hold the shade fixed in its inverted position. rl-he type of fastening-means shown in said Fig. 4. is that in which the cap is Xedly at- .'tached to the electric-socket.

Heretofore, with a lamp adapted for interchangeable illuminating-means, that is, for such as candle, oil, gas, or electric light-- ing, to change from one means of lighting` to another as from a. candle light to an electric light, the electric globe-socket, which is metallic, is entirely exposed to view. This detracts from the ornamentation of the lamp holder, which preferably is of wood finished with stain or polish.

lt will be manifest that my above described improvements permit interchangeability of various lighting means, and provide for inclosingl` the illuminating-member carrying-means of whatsoever shape is inherently necessary7 while still retaining the lpleasing design of the lamp.
