' 4 Claims. (01. 2404s) This invention relates to light fixtures and more particularly to a direct lighting fixture of the hanging or suspension type.

The object of the invention is to provide a direct lighting fixture of simple and inexpensive construction capable of being readily attached to the ceiling of a room or other enclosure and which will diffuse light in soft mellow rays free from glare and dazzling radiance and thus insure maximum illumination and visibility with miniseat in the adjacent offset portion of the retaining ring whereby positively to prevent accidental displacement of said bowl under all conditions of service. i

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efiiciency.

In the accompanying drawings forming a part of this specification and in which similar numerals of reference indicate corresponding parts in all the figures of the drawings:

Figure 1 is a front elevation of an electric light fixture embodying the present invention,

Figure 2 is an enlarged vertical sectional view taken on the line 2-2 of Figure 1, the hanger and its associated parts being shown in elevation,

Figure 3 is a transverse sectional view taken on the line 3-3 of Figure 2 with the upper globe and light socket removed, and

Figure 4 is an enlarged detail vertical sectional view showing the manner of clamping the lower bowl or globe to its seat.

The improved electric light fixture forming the subject-matter of the present invention comprises a tubular hanger 5 of any desired length having its upper end provided with a canopy 6 for attachment to a ceiling or other suitable support and its lower end fitting with a socket l for the reception of an electric light bulb, indicated at 8. Surrounding the socket I is a casing 9 having one or more lateral fingers Ill riveted or otherwise rigidly secured thereto and adapted to fit beneath a head or flange I l formed on an annular member or ring 12.

Spaced from the annular member 12 and rigidly connected thereto by inclined braces I3 is a retaining ring I4 of greater diameter than the ring I2 and provided withcircumferential steps or oiiset portions l5- defining seats l6 and Il adapted to receive the upper and lower bowls l8 and I9, respectively, of the light fixture. The upper seat 16 is disposed in a horizontal plane so as to permit the peripheral edge of the bowl l8 to rest flat against the seat while the lower seat I1 is inclined downwardly to conform to the. shape of the lower bowl I9. The opposite ends of the inclined braces l3 are given a half twist to provide terminal lugs 20 for the reception of bolts or similar fastening devices 2| and 22 whereby to connect the upper and lower rings together and form a strong rigid supporting frame for the glass bowls of the fixture. The lower fastening devices -22-extend through the retaining ring l4 and adjacent lugs 20 of the inclined braces and are threaded for engagement with clamping nuts 23. 'By' reference to Figure 4 of the drawings, it will be seen that the nuts 23 by engagement with. the peripheral edge of the lower bowl I9-serve to hold the bowlfirmly to its seat I! and thereby effectually prevent accidental displacement thereof. The fastening devices 22 thus perform the dual function of securing the lower ends of the inclined braces to the retaining ring and locking the lower bowl to its seat. A finishing ring 24 preferably surrounds the beaded portion of the upper ring I2 so as to give the fixture a neat attractive appearance. The upper globe I8 is preferably formed of white translucent glass While the lower bowl I9 is constructed of pale blue glass with an inner white translucent face so that, when the bulb 8 is lighted, the light will be difiused in soft mellow rays free from glare and dazzling radiance and thereby insure maximum illumination and visibility without danger of straining or otherwise injuring the eyes. The threaded ends of the bolts 22 are preferably of sufiicient length to form auxiliary stops so that in case the lower globe l9 does not contact the clamping nuts 23, the edge of the bowl will engage the threaded ends of said bolts and thus hold the lower bowl to its seat.

In assembling the different parts of the fixture, the lower bowl I9 is first positioned on its seat l1, after which the lower ends of the inclined braces l3 are fastened to the retaining ring by means of the threaded bolts 2'2 and in which positon the nuts 23 will bear against the peripheral edge of the lower bowl and lock it to its seat in the manner before stated. The upper bowl I8 is then fitted over the hanger 5 and allowed to rest on the fiat seat I6 of said ring with its upper end resting on the flared lower portion 25 of the annular member l2, as best shown in Figure 2 of the drawings. The socket casing 9 is then positioned on the annular ring l2 by introducing the ears ll] within said ring and causing them to engage beneath the bed I I, after which the finishing ring 24 is positioned over the bead I I and the hanger and canopy are attached to the ceiling in any desired manner. In order to remove or replace the electric light 8, it is merely necessary to elevate the upper bowl or globe I8 when access maybe readily had to the socket II], as will be readily understood.

An electric light fixture constructed in accordance with the present invention is strong and durable and will effectually support the glass globes of the fixture against accidental displacement and breakage under all conditions of service.

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

l. A lighting fixture including a supporting frame having upper and lower rings, one of which is provided with circumferentially stepped portions defining a horizontal seat and an inclined seat connected by an intermediate fiat vertical portion, inclined braces connecting said rings and having their lower ends bearing against said intermediate fiat portion, a lower bowl resting on the inclined seat, an upper bowl resting on the horizontal seat, and fastening devices extending through the stepped ring and the adjacent braces and bearing against the peripheral edge of the lower bowl for preventing accidental displacement thereof.

2. A lighting fixture including a supporting frame having upper and lower rings, one of which is provided with circumferentially stepped portions defining a horizontal seat and a downwardly and inwardly inclined seat connected by an intermediate flat vertical portion, inclined braces connecting said rings and having their opposite ends twisted to form attaching ears for engagement with the adjacent rings, a lower bowl resting on the inclined seat and an upper bowl engaging the horizontal seat, threaded bolts extending through the stepped ring and the attaching ears of the adjacent braces, and nuts threaded on said bolts and bearing against the peripheral edge of the lower bowl for holding said bowl to its seat.

3. A lighting fixture comprising a supporting frame including upper and lower rings, one of which is provided with an inclined flange and the other with circumferentially stepped portions defining an upper horizontal seat and a lower inclined seat connected by an intermediate fiat vertical portion, braces forming a connection between the rings, an upper bowl having its lower edge resting on the horizontal seat and its upper end bearing against the inclined flange of the adjacent ring, a lower bowl resting on the inclined seat, and fastening devices extending through the stepped ring and the adjacent braces and bearing against the lower bowl for holding said lower bowl in engagement with said inclined seat.

4. A lighting fixture comprising a supporting frame having an upper ring formed with a terminal laterally extending flange and a lower retaining ring circumferentially offset to form a horizontal upper seat and a downwardly and inwardly inclined lower seat connected by an intermediate vertically disposed fiat portion, spaced braces forming a, connection between said rings and provided with terminal attaching ears, an upper bowl engaging the horizontal seat and flange of the upper ring respectively, a lower bowl resting on the inclined seat, threaded bolts extending through the fiat intermediate portion of the retaining ring and having their inner threaded ends projecting over the peripheral edge of the lower bowl, nuts engaging the threads on the bolts, said nuts engaging the edge of the lower bowl and serving to hold said bowl to its seat, and a hanger operatively connected with the u per ring for attachment to a support.
