HARRY NORTHWOOD, OF WHEELING, WEST VIRGINIA.

SOCKET-COVER.

Specification of Letters Patent.

Patented Feb. 2'7, 1917.

' Application filed September 19, 1916. Serial No. 120,945.

To all whom it may concern:

Be it known that I, HARRY Non'rrrwoon, a citizen of the United States of America, and resident of Wheeling, countyof Ohio, and State of West Virginia, have invented certain new and useful Improvements in Socket-Covers, of which the following is a specification.

This invention relates to socket covers, and. it has for its primary object to provide a simple and inexpensive shade or globesupporting cover for electric light sockets, which may be readily-attached Without removal of the socket from its suspension cord or other support.

A further object is to provide a combined socket cover and shade support or holder involving parts which are telescopically nested or assembled, eliminating the necessity for providing screw threadstherein.

With these and other objectsin view, theinvention resides in the features of construcflector 3 through the neck of which said shell tion, arrangement of parts and combination ner shell B of approximately conoidal form. Said shell B comprises a substantially cylindrical body portion 7 an integral dome portion 8 and the intermediate shoulder portron 6 above mentioned, said body portion being adapted for introduction in close-fitting, or telescoped, relation to the body 1 of the outer shell with the dome portion 8 projecting upward above the flange 5.

The inner shell B is composed of two com- S plemental members or sections which are preferably of identical form, as shown, said of elements which :will hereinafter be exemplified, reference being had to the acc0m- V panying drawings, in which- Figure 1 is a vertical section'of a preferred form of the invention employed as a shade support; v

Fig. 2 is a similar section of a slightly modified form;

Fig. 3 is an enlarged section on the line 3-3, Fig. 2; and

Fig. 4 is a vertical section of a support for a heavy globe, also embodying my in vention. I

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views- A indicates a tubular outer shell composed of sheet-metal and comprisinga cylindrical body portion 1 having its lower end flared outward to form a supporting flange 2 adapted for receiving thereon in seated position the upper portionof a shade orirehas been introduced. Located at a suitable distance above said flange 2 is a series of annularly disposed, ventilation openings 4, a'sshown. The upper minates in an inturned flange 5 which is adaptedto overlie in seated relation an annular externalshoulder' 6 formed in an in- -their assembled relation.

sections having their meeting edges connected at one side, as by a hinge, to permit of said sections being opened and closed with respect to each other without destroying While any appropriate form of hinge connection may be employed, I prefer to use a wire loop 9 received 1n apertures 10 provided therefor in the adjacent vertical edges of the shell sections, as shown, said apertures being preferably slightly elongated horizontally to permit of increased freedom of opening movement of said sections with respect to each other. A central or axial opening 11 is provided. in the dome portion 8 in which the .socket suspension member or wire is re- "ceived while said dome portion rests directly upon the light socket (not shown).

To accommodate the hinge and thus prevent the latter from interfering with the introduction of the shell B within the shell A, the body 7 of said shell B may be provided with an inwardly pressed circumferential rib 12 whereby is end of said shell'terformed an external annular channel 13, in

which the hinge is located, as shown in Fig. 1; or, if preferred, slight-horizontal-indentations 13 may be substituted for said channel, as shown in Figs, 2 and 3, said indentations being of proper length and depth. In addition to serving the purpose mentloned, the rib 12 or the indentations 13, as the case may be, act to prevent the unhinged edges of the sections composing the shell B from passing each other, or assuming overlapped relation while beingintroduced within the outer shell A.

For concealing the collar or neck of the shade or reflector 3, a short flared apronlike ring loosely embracing relation to the body of the outer part of the i or shield 14 may be disposed'in I shell A, the same being adapted to have its lower end or edge rest upon said shade or reflector. Said shield is provided with a series of suitably located ventilation openings 15, as shown.

In the modification shown in Fig. 4, which illustrates a combination socket cover and support for heavy globes and the like, the outer shell A hasitslowerend flared outward to form a bell-mouth skirt 16 designed to encircle the neck or collar of the globe, as 17, to be supported, said skirt having clamping screws 18 directed therethrough for assuming impinging relation to said neck or col-' lar. In this form of device not only is the lower outwardly flared supporting flange 2 omitted, but the ring or shield 14 is also dispensed with.

In applying the invention, the shell A is first introduced upward through the neck of the shade which is to be supported, and the shield 14: is then slipped downward over said shell. Said parts are then together elevated to a position on the suspension cord a suitable distance above the socket. The sections of shell B are then spread apart at the side opposite the hinge for the introduction of said cord to a central or axial position, whereupon said sections are again closed upon each other to embrace said cord at a point between the socket and the parts previously applied, as aforesaid. Said shell B is then slipped upward along said cord and is telescoped to seating position within shell A; and, finally, the parts so assembled are permitted to drop to a position wherein the dome portion of shell B seats upon the, socket.

What is claimed is- 1.A combined socket cover and shade support comprising an outer shell having its lower end adapted for assuming supporting relation to a shade and having an inturned flange at its upper end, and a second shell adapted for introduction in telescoped relation to said outer shell, said second shell comprising a body portion and an apertured dome portion with an intermediate shoulder, said shoulder being designed to assume underlying relation to said flange, said second shell being composed of two similar complemental connected sections adapted for axial opening andclosing movement with respect to each other.

2. A combined socket cover and shade support comprising a tubular supporting shell, and a second shell telescoped within said'supporting shell and having an apertured dome portion projected upward from the latter, said shells having interengaging means for limiting the extent of upward telescopic movement of said second shell, said second shell being composed of two connected complemental sections adapted for axial opening and closing movement with respect to each other.

3. A combined socket cover and shade support comprising a tubular supporting shell, and a second shell telescoped within said supporting shell and having an apertured dome portion projected upward from the latter, said shells having interengaging means for limiting the extent of upward telescopic movement of said second shell, said second shell being composed of two complemental sections having a hinged connection which permits axial opening and closing movement of said sections with re spect to each other.

4. A combined socket cover and shade support comprising a tubular supporting shell, a second shell telescoped within said supporting shell and having an apertured dome portion projected upward from the latter, said shells having interengaging means for limiting the extent of upward telescopic movement of said second shell, said second shell being composed of two complemental sections, and means hingedly connecting said sections at one side only so as to permit axial opening and closing of said sections with respect to each other.

5. A combined socket cover and shade support comprising a tubular supporting shell, a second shell telescoped within said supporting shell and having an apertured dome portion projected upward from the latter, said shells having interengaging means for limiting the extent of upward telescopic movement of said second shell, said second shell being composed of two complemental sections, and means hingedly connecting said sections at one side, only so as to permit lateral separation of said sections at the opposite side for the introduction of a socket suspension member, said sections having means provided therein for receiving said connecting means in non-engaging relation with the tubular shell and for preventing the abutting free edges of said sections from assuming overlapped relation.

6. A combined socket cover and shade support comprising a tubular supporting shell, 2. second shell telescoped within said supporting shell and having an apertured dome portion projected upward from the latter, said shells having interengaging means for limiting the extent of upward telescopic movement of said second shell, said second shell being composed of two connected complemental sections, and an apron-like shield loosely embracing the lower part of the tubular shell.
