QLAMP-SHAZDE-FRAME, CENTER minimum,

Original No.11,695,223, aaieaf This invention relates, to lamp-i shade frames, and refers more particularly to an improved center element, constituting means for mounting lamp Sha de ,1 me on a pp rter holder. r l r present invention aims fortits; principalob1ect to prov de 'an-lmproved center element for a lampshade frame which is adapted tobeincorporated in and to become a substantially integral partthereof so that'a last- 1 "ing and rigid connection between the shade frame and center element is obtained, without resorting to welding or soldering processes.

. vThe invention more specifically contemplates a lamp shade frame center element which is spun, stamped or otherwise formed from sheet materialto provide a hub definmg a central opening and a sectlon extending outwardly from said hub, which section The invention furthermore residesin theimproved means for anchoring the inner termlnal ofeach arm or W1re between the outwardly extending section of the center element and the inwardly bent portion of, said section whereby to prevent radial displacement or relative movement between the element and arm in any direction.

Other objects reside the comparative simplicity of construction of the device, the economy with which the same may be produced and the general eificiency derived therefrom. a 7

With the above recited and other obj ectsfin View, reference is had to the following description and accompanying drawings, in which there is exhibited one example or embodiment of the invention, while the append ed claims define the actual scope Z In the drawings Figure 1 is a perspective view of the center element connected to the arms of a lamp shade frame.

Figure 2 is taken approximately on the line indicated at 2-2 in Figure 1.

Referring to reference, A designates the armswhich project radially inward from a lamp shade frame, not shown,and B refers generally to the centhereof.

= UNITED STATES ATEN' E the presentinventiom .which element is designed to serveas'a' means for mounting a lampshade frame on a suitable support such asthe' threaded end of the shell of an electric lamp socket or any other equivalent orholder, 1 v i The center element comprises a substan; tially cylindrical or tubular hub 10 having .an outwardly projecting annular flange or sec tion 11 atone of its ends,,,thesa idfiange or section 11 having a portion 12 bent" inwardly into a position substantially parallelto and underlying, the flange. The structure de scribed is spun, stamped or otherwise formed from sheet material and is provided at the uncture or connecting bight of the portion 12 with the section or flange 11, with the circnmferentially spaced openings 13 corresponding in number to the number of arms A. The hub 10 may be internally threaded as at 15 to engage over the shell of an electric isprovided with means to form a projection 18 on the inner surface of the flan e portion 12 and at the same time to forma epression in each arm terminal within which the projection 18 is received for the purpose of preventing radial outward movement of the arms. It thus follows that a centerelement has been devised which when incorporated in the shade frame forms a substantially integral and rigid part thereof so that a firm and lasting connection between the centerelement and theframe is obtained; It, therefore, follows that when the shade is properly mounted on a support, relative movement between the shade frame "arms and the center element is precluded, and this withoutthe necessity of welding, soldering or employing similar means of establishing a connection between the arms and the center element What is claimed is: s I a 1. A center element for mounting a lamp shade frame on a: support comprising a substantially cylindrical hub, a radially project ing Ushaped portion having an apertured bight, a radial arm extending through the apertured bight betweenthe leaves of the U- from one of the leaves recessed in the inner end of the arm for anchoring the same against radial outward and lateral relative movement with respect to the center element.

2. A center element for a lamp shade frame comprising a sheet metal member having a substantially cylindrical hub, an outwardly projecting section at one end thereof having an inwardly bent portion underlying said section, said section and portion at their juncture having an opening through which the lamp shade frame arm extends radially inward and means for anchoring the arm against radial outward and lateral movements comprising a recess in said arm and an inward projection of said portion engaging the recess of the arm.

3. A center element for a lamp shade frame comprising a hub defining a central opening and a section extending outwardly from said hub, said outwardly extending section having an inwardly bent portion apertured at its juncture With the section for receiving and gripping a lamp shade frame arm and an instruck projection from said inwardly bent portion, recessed in the inner end of the arm whereby said arm is anchored against radial outward and lateral movements.

4. A center element for a lamp shade frame comprising an annular member defining a central opening and a portion bent inwardly from the outer periphery of said annular member, said portion being formed with an aperture at the juncture thereof with the annular member for receiving therethrough, the arm of the lamp shade, said inwardly bent portion having an in-st-ruck projection recessed in the inner end of the arm whereby said arm 1s anchored against radial outward I movement.

Signed at New York, in the county of New York and State of New York, this 24th day of April, A. D. 1929.
