GLOBE-HOLDER FOR ELECTRIC LIGHTS.

' Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed. December 13, 1915. Serial No. 66,437.

To all whom it may concern:

Be it known that I, WILLIAM R. TOMP- KINS, a citizen of the United States, residing at Seattle, in the county of King and State of \Vashington, have invented certain new and useful Improvements in Globe-Holders for Electric Lights, of which the following is a specification.

This invention relates to globe holders, and is intended, more particularly, for use on lamp-posts or the like.

The object of the invention is the provision of an efficient holder for a globe and one in which the latter may be conveniently and rapidly applied to the holder or removed therefrom.

The inventionconsists in the novel construction, adaptation and combination of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a view partly in side elevation and partly in vertical section, of my devices attached to a bracket-arm and supporting a globe. Fig. 2 is a sectional view taken substantially through 22 of Fig. 1. Fig. 3 is a fragmentary sectional view of the globe and the attached clamping collar therefor removed from the holder. Fig. 4 is a detail elevational view of a portion of the clamping collar.

The reference numeral 5 designates part of an arm which may extend from a post and, as illustrated, is arranged to sustain a depending light. Secured, as by a nut 6 threaded on an extension 7 of said arm, is a casting 8 having, desirably,concentrically arranged flanges 9 and 10 to afford an annular groove 11 therebetween to accommodate the flange portion 12 of a light globe 13 and also the clamping collar which is detachably secured to such globe flange. Said clamping collar is formed with a substantially horizontal flange 14 which extends inwardly from a peripheral flange 15 which is inclined inwardly from its juncture with the horizontal flange 14c. Said clamping collar is adjustable to fit various sizes of globes by the provision of outwardly directed ears 16 at opposite sides of a gap in the collar and an adjusting screw 17 which passes through an aperture in one of said ears to engage a screw-threaded aperture provided in the other car. Formed integral with said collar are a number of spaced hooks 18 which are adapted to be inserted through slots '19 of the holder and engaged with the latter by imparting a rotary movement to the clamping collar.

20 is a tapered key engageable in one of the slots 19 to the rear of a hook to secure the collar in hooked engagement with the holder. Ridges or projections 21 may advantageously be provided on the holder at each of the slots 18 to divert rain water from draining into the slots.

The aforesaid globe-holder is not only used to support a depending globe, but is also employed in an inverted position to that shown in Fig. 1 with the holder supporting the globe from below.

To apply the device, the collar is first clamped through the instrumentality of the screw 17 to the rim or flange 12 of the globe. Being thus coupled, they are introduced into the groove 11 of the holder so that the hooks 18 will pass through the respective slots 19, whereupon the coupled globe and collar are turned to cause the hooks to engage the holder and finally the key 20 is inserted in a slot to the rear of a hook to prevent the disengagement of the hooks.

l/Vhat I claim, is

1. A device of the character described, comprising a holder provided with spaced slots, a collar formed with angularly disposed flanges, means to contract said collar for clamping the same to a globe so that the rim-flange of the latter will seat in the recess aflorded by the collar flanges, and means provided on the collarand arranged to extend through the slots of said holder whereby the collar is detachably secured to said holder when the collar is suitably turned.

2. A device of the character described, comprising a holder provided with spaced slots, a collar terminating in outwardly directed ears, a screw engaging said ears to clamp the collar to a globe, and hooks provided upon said collar and arranged to pass through the respective slots to engage the holder when the collar is rotated.

3. 'A device of the character described, comprising a holder provided with spaced slots, a collar adapted to be detachably connected to a globe, hooks provided upon said collar and arranged to pass through the re- Signed at Seattle, Washington, this 23rd spective slots to engage the holder When the day of November, 1915. collar is rotated, and means insertible in one WILLIAM R TOMPKINS.

A of said slots and in juxtaposition With the 5 respective hook for releasably securing all Witnesses of said hooks in engagement With said PIERRE BARNES, holder. E. PETERSON.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. Washington, D. C.
