Specification of Letters Patent.

Patented J unc 2, 1914.

Application filed Getober 25, 1913. Serial No. 797,322.

To all whom it may concern Be it known that I, WILLIAM EDWARD LANE, a citizen of the United States, residing at Kansas City, in the county of Jackson 1 and State of Missouri, have invented certain a device of this general character wherein 1 the efficiency of the illumination is materially increased.

The invention consists in the details of construction and in the combination and arrangement of the several parts whereby cer tain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advan tageous'for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a sectional View taken through a lamp fixture constructed in accordance with an embodiment of my invention; and Fig. 2 is a view in elevation, partly in sec tion, of a part of my improved lamp fixture, as herein contained.

As disclosed in the accompanying drawings, 1 denotes a base of. cylindrical form and produced from suitable insulating ma terial and being provided on one end portion with the metallic screw shell 2, whereby the same may be caused to properly engage a conventional socket and being provided at substantially its axial center with the conducting element 3 adapted to be properly engaged with the usual contacts of the socket member to afford the requisite flow of electrical energy for illuminating the lamp to be hereinafter referred to. The opposite end portion of the body 1 is provided with a metallic screw shell disposed in sub stantial continuation of the shell 2 with the threads thereof in reverse relation and adapted to be engaged by the threads 5 produced interiorly on the annular flange or collar 6 depending from a metallic plate member 7 provided at substantiall its axial center with a threaded opening 8 adapted to aline with the conducting element 3, hereinbefore referred to, such conducting element terminating a distance slightly below the end of the base 1 adjacent the plate and thereby affording a supplemental socket 9 int-eriorly threaded and such opening 8 and socket 9 are adapted to receive the lamp base 10 of conventional form and adapted to contact with the conducting element 3, whereby the lamp 11 carried by such base 10 may be caused to illuminate.

The lamp 11 is of a miniature type and it will therefore be observed that the base 1 and its concomitant parts serve as an adapter whereby a miniature lamp may be applied with convenience and facility to a standard lamp socket.

In order to increase the eilicicncy of the illumination afforded by the lamp 11, l have the same projected through the smaller end of a frusto-conical body 12 possessing the requisite reflective qualities, such smaller end being provided with the annular flange 14: of requisite diameter adapted to bear against the outer face of the plate 7 and adapted to be suitably engaged whereby the body 12 is held against displacement. I also find it of advantage to inclose the lamp ll and the body 12 within an outer casing or globe 15 of suitable transparent material which is also adapted to be maintained in operative position relative to the plate 7 and, as herein disclosed, the periphery of such plate has detachably engaged therewith a ring 16 provided with an inwardly directed flange 11" adapted to overlap an outwardly directed annular flange 18 formed at the lower or open end of the'globe or casing 15 whereby the same will be effectively held against displacement and, as herein disclosed. it will be observed that the flange 14 is of such a diameter as to project between the plate 7 and the flange 18, whereby the ring 16 together with its flange 17 serves as an effective means for holding the same in proper operative position. I wish to state, however, that other means for maintaining the cas ing or globe 15 and the body 19 may be employed if the requirements of practice should so dictate.

From the foregoing it is thought to be ob vious that a lamp fixture constructed in aw the increased efliciency afforded by its illu-' mination, and it will also be obviousthat my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. A device of the character described insignature in the presence of two witnesses.

v eluding a base formed of insulating material, a metallic screw shell disposed there around, a metallic plate adapted to bear against an end of the base and provided with means adapted to engage the shelL'a con- Copies of this patent may be obtained for five cents ,each, by addressing the Commissioner of Patents,

ducting element extendedthrough the base,

vinclosing the lamp and reflector and provided with an annular outwardly directed flangein-contact with the flange of the ref flector, andremovable means carried by the base overlying the flange of the globe, wherey such globe and reflector are maintained in assembled relation.

Intestimony whereof I hereunto aflix my WILLIAM EDWARD LAN E Witnesses:

D. E. Omar; ARTHUR JOHNSON.
