LIGHT FIXTURE FOR BEDSTEADS AND OTHER ARTICLES.

Application filed May 14, 1926. Serial No. 109,023.

My invention is a fixture for bedst'eads and other objects, designed to ai'iord illuminating means for the convenience of a reader while resting at ease. Although the fixture is useful, more particularly, in connection with a bedstead to meet the requirements for illumination of a reader while lying in bed, still it .is apparent that the fixture may be used in connection with other articles of furniture, and, further, that it may be used in other relations.

In a fixture of the character under consideration, it is desirable that provision be Broadly stated, my invention is embodied.

in a reflector-supporting member engageable frictionally with parts of the reflector for retaining the latter in either of a plurality of operative positions. a

Other functions and advantages of the in,- vention will appear from the following description taken in connection with the drawings, wherein V V Figure 1 is a View partly in side elevation and partly in longitudinal section of a bed light fixture embodying the invent-ion.

- Figure 2 is a cross section, on the line 2-2 of Figure 1.

Figures 3 and 4 are longitudinalsectional elevations of other embodiments of the invention in bed light fixtures.

A is a hood constituting a reflector mounted to encase, at least partially, a source of light afforded by an incandescent lamp B. The reflector is a casing substantially arcuate in cross section, see Figure 2, said casing being closed at the ends by heads, a, and open on one side by the provision of a wide aperture or slot 7). The reflector is rotatable on a longitudinal axis afforded by journals entering the heads, a, whereby the reflector is mounted in a manner to permit it to be rocked or turned for changing the opening I) directing the rays of light in a desired dircction. Preferablygthe hood is composed of metal, and the innersurfaces of the hood, including the heads a, are coated with a suitable light refiecting medium, the coating being of any desired material or substance.

For rotatably supporting the "hood, I employastirrup-or. yoke,lC, the same being shown as comprising a straight longitudinal member, 0, and a plurality of arms, 0', extending at an angle to member 0, at the opposite ends thereof. 'I'he hood, A, and yoke or stirrup, C, may be arrangedin various ways, as e. .g. the yoke maybe positioned within the; hood as in Figures 1, 2 and ,4;

. or said yoke maybe arranged exteriorly relatively to the hood, asin Figure 3; but-whatever the relative arrangement may be, the

hood is rotatably supported by, and frictionally engaged with, said yoke. The frictional engagement. is obtained by the spring" or elasticity inherent in the arms, 0, of the yoke, and such frictional relation and pivotal connection is useful in obtaining the rotatable movement'of the hood, and in retaining said hood inthe diflerent positions to which said hood maybe moved or shifted. In the particular example offrictional and pivotal relation of hood to yoke shown, I employ disks, D, having trunnions, d, 03, each disk being interposed between one arm, a, of the yoke and one head, a, of the hood, Whereas the trunnions (Z, d, are fitted loosely in apertures provided in the yoke arms cand the hood headsa, respectively. The elasticity of the yoke arms 0 presses the disks D into frictional. contact with the. closed ends or heads a of the hood,'whereas the trunnions d, d, aflo'rd the axis on which the hood may be turned as required. Obviously, the attendant is required to apply some pressure to the hood for turning it to overcome the frictional contact due to the elasticity of the arms 0 in' pressing the disks D against the hood heads a; but when the hood shall have been shifted, and the pressure is removed, then the yoke coacts with the friction disks in holding said hood in the position to which The yoke or stirrup functions" as the primary support for the rotatable hood, but for fixedly attaching the yoke or stirrup on the bedstead or other article, I may employ 5 various forms of attaching devices, examples of which are depicted in the drawings.

In one form,-shown in Figures 1 and 3, the yoke is fixedly attached at two points, but in Figure 4. a single attaching 'means is used centrally of the yoke. The two part attaching means for Figures 1 and 3 embodies a short post, E, with a screw, engageable near one end of the yoke and fixedly attached to the article, and it embodies, also, a longer post, F, with provision for the accommodation of the electric cable, G, and a lamp socket, H. The longer post, F, is hollow and provided with a col lar, f, and is threaded at f, for the reception of a-sleeve nut, g, flanged at g. Cooperating with the tubular'post F is a spac ing sleeve or collar, I, fitted loosely on the tubular post, with one end contacting the stirrup, C, and the other end engageable with the bedstead, see Figure 1, whereby the operation of tightening the sleeve nut g on the threaded post 7 draws the collars f, g, and the ends of the spacing sleeve or collar I into engagei'nent tightly with the bedstead and the yoke C for fixedly holding said 'yoke C and the lamp fixture as a whole in firm connection with the bedstead or other article to which the fixture is applied. The posts E, F, pass from the out side of the hood to the interiorly positioned yoke or stirrup C within the hood, and to allow for the turning or rotating move ment of the hood relatively to the yoke, I provide slots 2', 2", in the curved part of the hood, said slots being at or near the ends of said hood and accommodating the posts E, F, so that said posts act to support the yoke G'fixedly in place, whereas the slots 2,2", allow for the pivotal movement of the hood with respect to the posts E, F.

With the yoke C arranged 'exteriorly to the'hood, it is necessary to-provide a single slot, as i in the hood for the accommodation of the longer tubular post F. It will be noted that in Figure 2 a short post E and screw 0 are used near one end for the outside yoke, whereas the longer tubular post F passes through the slot 2' and through the yokeC, in'order that it may afford the support for the lamp socket H.

Again, the yoke or stirrup may be supported centrally and at a single point, as in Figure 3, but inthis form of construction, the hood is slotted centrally and at a single place, as at. i to accommodate the fixture post F and the parts associated therewith, whereby the slot 2' in the hood allows said hood to turn on the axis afforded by the trunnions d, 62, such turning of the hood by reason of its slot 2'? taking place relatively to the tubular fixture post F. In this form, the lamp socket II should be attached fixedly to the yoke or stirrup, and for this purpose I provide a short member .H which carries the lamp socket II and is attachedina "0 desirable manner to the yoke C, suitable provision being made as a slot, j, for leading the cable, G, from post, F, to membcr H, and thence to the, usual terminals of the lamp socket H.

It is apparent that the lamp socket H may be of any desired kind, such as the pull chain socket shown, andthat various details of the form and constructions shown may be changed by a skilled constructor within the limits of my invention.

Having thus fully described the invert tion what I claim as new and desire to secure by Letters Patent is:
