Application filed March 31, 1913. Serial No. 757,304.`-

Be it known that I, HARRISON D. MoFAD- DIN, a citizen of the 'United States, residing in the city 0f East Orange, county .of Essex, and State of New Jersey, have 1nvti'a certain new and useful Lamp-Fixture, of which the' following is a specifica-` tion.' a

`Tghis'invention is a lamp bracket intended, more particularly, for use with bed lamps, its function being that of securing a lamp to a bed-post, or analogous supporting means, in a simple, efficient and secure manner.

The invention embodies, I also, -improvements wherein the lamp may be mounted on either a vertically or. horizontally extending portion of the bed and securely locked against displacement.4

From a more specific standpoint, the invention is particularly designedI for supporting a lamp on metallic bedsteads, and, as the posts of such beds vary in shape, the

present invention embodies means whereby the bracket or fixture readily adapts itself to all such shapes ordinarily employed.l

Other Vfeatures and advantages w1ll be apparent from the following detailed de-4 scription read in conjunction with the accompanying drawings. In said drawings, one practical embodiment of the invention and the application thereof to` supports of different shapes, is shown, but these drawings are to be understood as illustrative,

only, and not as dening the scope or limits of the invention.

Figure l is a perspective view showing a lamp fixture of the present invention in place upon averticallyiextending circular post of a metallic bedstead. Fig. 2 isa cen- Vtral, horizontal section through the fixture. Fig. 3 is a central vertical section thereof. Fig'fv'llis a plan viewshowing the applicationoftlie rfixture to a horizontally disposed supporting member. Figs. 5 and 6 are fragmental sections,similar to the section' shown in Fig. 2, illustrating theapplitation of the'lixture to bed-posts, or other supporting means, of varying shapes. Fig. 7 Ais. a perspectiveview of a threaded nut In said drawings, A denotes a casing which, although shown rectangular in crosssection, may, in some cases, be varied as will hereinafterV be more fully described. The casing-'is made open at both ends, and

into its'forward end is adapted to be fitted.

Vthe shank ,b2 of a plug B, which plug carrles the illuminating means.

As the embodiment of the invention shown is more specifically adapted for use in combination with electric fixtures employing my well- Vknown Emeraiitellsliadea and, since these shades .areof elongated shape," as shown in dotted lines in Fig. 1,1 the plug B is provided with laterally extending varms C, C, to which the lamp shade is. secured by any well-known means. l l

The electric la'mp (not shown) which furlnishes the light is supported in the usual socket which screws onto the nipple c', at the outer end of' the arm C, and the elec tric wires w, for furnishing the power to said lamp are led through a hole a, in the casing, forwardly therethrough, and from thence to the lamp through a duct c, provided for'this purpose within the plug B, and the arm C.

The casing A, is enlarged at the rear end thereof, as at D, so as to give additional thickness of material and consequent increase of. strength at this point. Two opposite sides of this enlarged portion D,.are cut away, at d', leaving the portion D composed of merely two rearwardly extending parallel flanges ci, d. A flexible strap E, substantially equal to, or less in width than, the inner dimension of the casing B', is

adapted to lie intermediate its length, be2;

tween the flanges d, in such a manner as to lie flat across the open end of said casing.

Moreover, the strap is provided with an aperture e, at such intermediate point, so that, when positioned as aforesaid, said apcrture will lie in the medial line of the casing.

The plug B, which closes the front end of the casing, is, like the strap E, aperture'd in the central medial line of the casing. A bolt plug B, longitudinallv through the casing A, through the aperture e, in the strap, be-

yond which it threads into a nut G. This nut is cut away, as at g, so as not to interfere in its operation with the wires w which supply the electric current to the lamp. Thus, if the bolt is turned to draw the nut into the casing, the strap will. be drawn I" is passed through thev aperture in the rio strap are passed about a bed-post, or other support, the ends thereof being secured t0- gether by the catch member e. While the bolt F is being turned to draw Vthe nut G into the casing A, this nut is carrying a portion of the strap with it, thereby causing the remaining portion thereof to be tightly wrapped about the supporting post, and the enlarged end of the casing to be brought into gripping engagement with said support. In other words, the casing is drawn tightly against the support as a result of the pull exerted upon the strap by the bolt, whereby said pull operates to securely retain the fix` ture on the support.

A salient feature of the invention is its adaptability for application on supports of various shapes. Figs. 2, 5 and 6 illustrate its application to the cross-sections most generally employed in bedstead construction, said figures clearly showing how the flexible strap adapts itself to the shapes illustrated. Moreover, certain details of construction are provided to insure proper engagement Abetween the fixture and its support. More specifically speaking, the fixture is very `well adapted to engage with a round section X, Fig. 2,by virtue of a pair of clamping jaws I, I, which are disposed in 'parallel relation to one another, on a pair of pivoting pins z', i', fixed between the fianges d. d of the enlarged portion of the casing. Looking at Fig. 2, it will be seen that, when the strap is drawn into the casing, it is just stiff enough to lend itself to an easy curve which engages with the clamping members I, I, and forces said members into engagement with the support. Thus, when the bolt is screwed up tightly, the pull on the strap will be sharedby the pins z', z", and said strap. j

While the clamping means, just described, is highly meritorious in providing engaging means which will not scratch or dent the support, I wish it understood that 'its use is not compulsory to the satisfactory operation of the fixture and that, if desired, it maybe dispensed with.

The application of the bracket to a support presenting a fiat face is clearly illustratedin Fig: 6, which shows how the fiat ends of flanges d, d on the enlarged portion D of the casing furnish a maximum bearing surface against the side of the square section 'X2 In Fig. 5, it is clearly evident that the ends of the flanges d may be notched,

as at d3, to coperate with a support pre-l senting a corner, as the diamond-shaped section X. In the two last described applications of the device, the clamping members I, I, do not play so important a part as in the first application, but, if the fixture embodies the clamping members, the flat ends Vand the notches z', z", therein, it is obviously adapted for engagement with almost every `conceivable shape. VFurthermore, as the with it, and thus loosen the bracket from its support. Accordingly,jin practice, the/bolt head f, is preferably made polyhedral and -is adjusted by means of a key or wrench (not shown) similar to a bed wrench. Moreover, the operation of the device is greatly facilitated if the bolt is fixed against longitudinal movement, so that, when unscrewed, the strap E will be loosened and pushed out of the casing instead o f the bolt backing out, as it would be apt to do. To this end, the head of saidbolt is provided with a circumferential iange f at -the base of its polyhedral portion, and a pin or set screw f2 is tapped intol the plug in such a. manner 4as to engage the outer face of said flange, thereby holding the bolt against withy drawal.

As before stated, and clearly shown in dotted lines in Fig. 1, the lamp shade which I prefer t0 employ has an elongated horizontal axis. Accordingly, it is requisite to the proper mounting of this shade that the arms C, C', onrthe plug B, are, when the bracket is fixed to its support, in a substantially horizontal plane. In view of this requirement and the further fact that I` desire to provide a fixture which may be secured to.

either a vertically or horizontally disposed portion of a bedst/ead, the fixture allows of the adjustments next to'be described.

If the fixture is in the position shown in Fig. l of the drawings, .e., on a vertical post of a bedstead, and it is desired to transfer itV to a horizontally disposed portion of said bedstead, the bolt F is loosened, and the catch members e disengaged from one another to detach the fixture from' the bedpost. The shank b2, of the plug, whichis loosely fitted into the forward end of the casing B, may now be withdrawn therefrom and out of engagement therewith (see dotted lines in Fig. 3), after which said plug may be given a quarter turn and then insertedagain into the end of said casing. The fixture may now be secured to the horizontal support, as shown in Fig. 4, in the manner hereinbefore described. The foregoing adjustment is, because of the rectangularcrosssection of the casing shown, limited tothe variations of ninety degrees. It will be manifest, however, that,.if the forward end of said casing were made polyhedral and the stem of the plug correspondingly formed, the scope of adjustment would be increased things., the. specific mounting of a shade of` particular form is pointed out. Itfis not intended, however, to limit'the -invention to this embodiment, a's, obviously, this detail ofconstruction might be varied. I may, if desired, mount a lamp directly upon the plug and,'moreover, dispense with the shade. These features are immaterial, Therefore, for these and other obvious reasons, I do not wish to be understood as limiting myself any further than the stategof the art may require. y l While the invention has been particularly described with reference to its employment as a lam'p bracket, it will be understood of course, that certain parts thereof areequally adapted for use in analogous relations..-
