LAMP BELL FOR GLOBES AND SHADES. it

Application filed April 20, 1926. Serial 110. 102323.

,rom'mon toaprovide a shank or stem whereon' is mounted a bell proper within which are provided globe supporting fingers the rim or neck of the globe being grasped between these, fingers and the edge or rim of the bell, the finger supporting the weight while the bell rim holds the globe from slipp ng. Owing to inequalities in the thickness ofthe globe neck and imperfections in the for mation of the bell and fingers an equal grip off the fingers on the globe is freqnent-ly not obtainable with the ordinary construction.

One important object of the invention is to so improve the general construction of devices of this kind that the fingers will grip the globe equally under all the usual variations found in thickness and shape of the several parts.

A second important object of the inven- 'tion is to provide-improved means, in such devices, for rockingly supporting the fingers, a third important object of the lnvention is to provide an improved globe support having a bell slidably nounted on the supporting shank to move lnto and out of cooperative relation with certain tilting fingers' so that the globe may be readily placed on or removed from the device.

W'ith the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations 'of parts hereinafter fully described, illustrated in the accompanying drawings and specifi-- cally claimed.

In the accompanying drawings like char acters of reference indicate like parts in the several views, and

line 3 3 of e line In theembodiment of the invention herein disclosed there is employed a tubular shank or stem 10 having secured to its lower end a lamp s0cketi11 of ordinary construction. Above the socket 11 the stem passes through an elongated opening 12 formed in the honzontal portion 13 ot' a finger bar having downwardly and divergingly extending armslal terminating at their lower ends with vertical portions from which extend globe gripping fingers 15. The horizontal portion 13 rests on a cross bar 16 which extends diametrically through the stem and lies transversely of the finger bar, being provided at its ends with rebent portions 17 gripping the edges of the fingenbar so that the vlatter 1a, in efleet, pivoted to-the stem.

Slidable and rotatable on the stem 10 is a sleeve having a threaded body 18 provided at its lower end with a hexagonal head or flange 19 i'or'engagen entby a wrench or the like. On this sleeve is screwed a lock nut 20 and on top of this lock nut rests the central part of a bell 21' of suitable ornamental form and preferably made from stamp-ed or spun metal, a suitable opening being provided for the passage of the stem 10. The lower edge of this 'bell is in the form of a depending skirt 22 provide .with head 23 and the lingers 15 extend outwardly somewhat beyond the bead so that the globe,

and fingers 15. At the upper part this bell is provided with ventilating openings 24 and on top of the bell restsa'cap 25 having an internally channeled edge 26 spaced from the bell and covering the openings 24, the spacing of the channel permitting escape of the air which may enter the channel through the-openings 2 1. To hold .the cap and bell firmly in position asuitable nut 27, having an internal flange 28 at itsupper end, is screwed on thethreaded sleeve 18 until the flange 28, fitting closely on the stem, engages the end of the sleeve where upon the-nut 20 is adjusted to clamp said cap'and bell against thedowerend of the nut 27. Both thesleeve 18 and flange 28 are provided internally with grooves 29 alined With each other upon the nut 27 being properly positioned. 011 the stem 10 is a pair of vertically spaced

studs

30 and 31,

the lower stud 30 engaging the flange 28 when the bell is in globe engaging position. These studs are of such size as to pass through the grooves 29 upon the latter being brought into vertical a'linement with \r p v a stud and thus by sopositioning the'g-rooves raised the globe may be placed in position by first inserting one arm of the fingerv bar through (the opening in the top to a considerable extent and. then 'moving the globe until the other finger passes through the opening.

The globe is then straightened and centered on the fingers after which the bell is moved to lowered position, the fingers tilting on the bar 16 to give an equal grip for each finger. I

As a means'of suspending the device a cap 32 having a ring 33 may be screwed on top of the stem 10. A modified form permitting the sleeve to passoif the stem is shown in Figure 6.

eiiicient device of the, the purpose specified;

It is obvious that minor changes may be made in the form and construction of the invention .without departing from the material spirit thereof.- It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

1. A lamp shade support including a vertical stem, a cross bar extending diametrically of the stem and a finger bar having a centrally dispose elongated opening through kind described and for which. the stem passes, said finger bar resting on the cross bar with the latter extending transversely of the finger bar, the said finger-bar being fixed to the cross bar for' transverse tilting therewith.

2.1 Alampshade support including a vertical stem, a cross bar extending diametricallyof'the stem, and a finger bar having a centrall disposed elongated opening through which t e stem passes, said finger bar resting on the crossbar with the latter'extending transversely of the finger bar, said cross bar having 'rebent end portions gripping the edges of the finger bar and extending over the topthereof to prevent disengagement of the fingerbar from the cross bar, the said finger cross bar. v

3. A lamp shade support includingavertical stem, a finger bar having a central portion provided ,with an o ening through which the stem passes, sai opening being larger than the stem to permit tilting move-. ment of the finger bar on the stem, said finger bar having a plurality of arms extending outwardly from. the central portion v and provided. with terminal shade engaging a-r being tiltahle transversely of the port-ions engageableunder the neck portion and a linger bar-extending on opposite sides of saidstein and havingpivotal connection centrallyof the bar with said stem; in combination with a bell slidable" vertically on thestem between lowered shade. engaging :and raised "Shade freeing positions, and
