HENRY A. TORREY, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE PLUIIE 6: ATWOOD (30., OF WATERBURY, GONNECTICUT, A CORPORATION OF CONNECTICUT.

SHADE-HOLDER FOR ELECTROLIEBS.

To all whom it may concern:

Specification of Letters Patent.

Application filed March 25, 1909. Serial No. 485,642.

Be it known that I, HENRY A. Tonnnr, a

citizen of the United States, residing at ater-bury, in the county of New Haven and State of Connecticut, have invented an improvement in Shade-Holders for Electroliers, of which the following is tion.

My invention relates to a shade holder for electroliers regardless of the character of the electrolier and regardless of the characa specifica- .ter of the incandescent lamp connected therc- I with, for the electrolier may be suspended from the ceiling, connected to a side wall, or portable to stand upon a desk or table; the special object of my invention being to adjust the position of the globe or shade with reference to the center of the incandescent lamp so that the lamp may not only be protected but so that the rays of the lamp will be thrown as equally as possible in all directions. 7 In the device of my invention, the shade holder is made of two parts axially-mo "able with reference to one another and adapted for connection in any one of several axial positions; it being understood that one of these parts is at one end connected in a fixed relation to the sleeve or the lamp socket, or more properly speaking, between said parts and to the union that connects them. The free end of one of these members or shells is cylindrical and threaded and the other memher is in the form of a sleeve or annulus, a

part of which is threaded to screw over the threaded portion of the other member, with the free end of the exterior member adapted to receive the flanged portion ofthe globe or shade which is clamped thereto by the usual clamping screws, and as a connecting device in the adjustable relation of these parts, I prefer to provide a wire spring having a projecting or looped part passing through a hole in the threads of the shell member and adapted to engage any one of, a number of spaced holes in the sleeveor annulus as the parts are screwed together or unscrewed axially, and in this manner the position of the globe or shade with refer: ence to the incandescent lamp is adjusted, all of which is hereinafter more particularly described.

In the drawings Figure 1 is a vertical section and partial elevation representing, the device of my improvement. Fig. 2 is a switch of usual construction.

Referring particularly to 1, a represents the lamp socket and a. theswitch body of the lamp socket. 2 represents a pull Z) is a sleeve member to which the lamp socket is secured and c an arm or part ofanelcbt-rolier com nected to the sleeve. d represents a conoidal shell connected at the smaller closed end between the lamp socket and the sleeve 6 and forming a substantial unit with said socket. This conoidal shell is preferably of open-work sheet metal for lightness and appearance as shown in Fig. 1. thereof however, is in the form of a cylindrical member a circumferentially thereinand continued to the very edge. 1

The member (Z is provided with an opening adjacent to the lower edge and within said member I provide a spring wire about the form shown particularly in Fig. 2, in which one end is secured by solder to the sheet metal and the free end provided. with z loop or projection 5 adapted to pass through the opening in the said member al Surrounding the threaded portional is a closely fitting sleeve or iug a screw-thread pressed intothe and the thread of this sleeve or Mifii meshes with the screw-thread of the part ti is' zi tlapted to be turned about the part thus imp ing to the sleeve or annulus c a longitudinal motion or 'illOilOIl axially on the part CP. The lower portion 0 of the part c is of slightly greater lia"n1eter and without screw-thread but provided with clamping screws 3a-t spaced intervals and preferably with a rolled lower edge to stiffen the same. This lower portion 0 is adapted to receive the curvedflange at the upper end of the shade or globe and the screws 8 serve to support the same in position. The annulus or. sleeve 6 is provided with spaced apart holes 4 cut through the raised ortio'ns of the convolutions of the screw thread and any one of these holes is adapted to receive the loop part 5 of the spring g according to the position of tlie' Fig. 4; is vertical The free end with a screw thread pressed annulus :2 also ha-vportion secure springs 7 with loop portions 2.0

into any of the oppositely placed openings v, equally for the longitudinal movement of socket and an integral cylindrical part, and

may with equal advantage be placed as the upper edge and the portion 03* with a sleeve 6 in its relation to the member (P; Fig. 3 shows these holes 4: and the preferable spaced relation thereof.

In Fig. 1 I have shown parts of globes 'diflering in shape and Configuration, the globe 1 being circular in vertical section and the shade f being flaring. I do not limit myself to the shape or kind of globe or shade.

In the form of my invention shown in Fig. at, I dispense with connecting screw threads for the cylindrical portion of the conoidal shell and annulus sleeve and make both'the cylindrical portion (Z and the an-. nulus sleeve 0 plain and telescoping and provide spaced apart openings 6-in the annulus sleeve? on opposite sides, and upon opposite inner surfaces of the cylindrical passing through openings in the portion (Z of the annulus sleeve'e While the springs 7 connect the parts (Z and 6 it is obvious that the annulus sleeve 6 may be readily inoved vertically of the cylindrical base (Z and while I havev shown the springs 7 placed vertically it is also obvious that they shown in Figs. 1 and 2, and be operative by a turning action of the part 6 prior to the longitudinal movement thereof.

In the form of my invention shown in Fig. 5 I havevaried the means of connecting the annulus sleeve 6 to the cylindrical portion (i by providing the sleeve with an inclined slot 8 with semi-circular notches in pin 9 adapted to move through the said slot and restifor' be support of the sleeve 6 and shade or g obe in any one of the said notches. I

All these forms'of my invention provide the; sleeve upon the cylindrical portion of the shell and its adjustable connection therewith according to the desired position thereof.

I claim as my invention:

1. The combination with the socket of an incandescent electric lamp and a support therefor, of 'a holder fora shade or globe comprising two members one of which is adapted for connection withthe said socket and the other ofwhich is adapted together with the shade or globe for an axial and telescoping movement upon and with reference to the-first aforesaid part.

The combination with the socket of an incandescent; electric lamp and a support therefor, of a holder for a shade or globe comprising a, member having a conoidal p'art adapted for connection with the said a member adapted to surround said cylindrical part and to be axially movable therel on and means for connecting said members together in a rigid but adjustable relation.

3. The combination with the socket of an incandescent electric lamp and a support therefor, of a holder for a shade or globe threaded part and to be axially mo able thereon and i ueans for connecting said members together in a rigid but adjustable relation.
