LIGHTING FIXTURE.

Application filed. May 25,

This invention relates to light fixtures.

Objects of this invention are to provide a novel'type of light fixture adapted to receive a globe or similar shade for a hght, and so constructed that the globe may be attached without the use of screws or other fasteners, but through the medium of supporting members and a cooperating canopy with the canopy cooperating with the sus pension link to lock the globe in place and freely movable to release the globe when desired.

Further objects are to provide a device which may be produced with the utmost facility, which is inexpensive to construct, and which may be readily handled even by an unskilled operator.

An embodiment of the invention is shown in the accompanying drawings in which:

Figure 1 is a sectional View taken on the line 11 of Figure 2 showing the fixture;

Figure 2 is a sectional view on the line 2-2 of Figure 1;

Figure 3 is a detail fragmentary view of a portion of the head and a portion of the end link and canopy.

Referring to the drawings, it'will be seen that the device comprises a lamp receiving socket 1 which is secured to an upwardly projecting head 2 by any suitable means as, for example, by means of the screws 3. These screws pass through the horizontal portion 4 of a relatively heavy spring-like supporting strap 5 provided with outwardly projecting arms 6 adapted to fit beneath the inturned flange 7 of the light globe, a portion of which is shown in Figure 1.

The head is provided with diametrically opposed apertures, one of which is indicated in Figure 3 by the reference character 8, and these apertures receive the inturned ends 9 of an end link 10, the end link being suspended in any suitable manner as by means of the successive links 11. A canopy 12 is provided with aebeaded lower edge 13 adapted to bear against the flange 7 of the globe when it is positioned. This canopy is provided with a central aperture through which the head 2 passes. This central aperture is (provided with a pair of diametrically oppose notches 14 as may be seen from Figures 2 and 3. These notches are adapted the link 10.

1928. Serial No. 280,629.

to pass the inturned ends of the link 10 so that the canopy may be freely slippeddown over the link 10. After the canopy is in place, it is given a quarter turn to the position shown in Figure 2, for instance, so as to lock the upper flat face 12' of the .canopy beneath the shoulders formed by the bottom parts of the inturned portions 9 of Figure 3 shows the position of the parts when the canopy is turned so as to pass the link. Figure 2 shows the position of the parts when in locked relation.

In using the device, it is merely necessary to turn the canopy so that the notches 14 register with the link and thereafter raise the canopy slightly. The globe may be positioned upon the supports 5 and its flange may rest upon the arm 6. This is easily accomplished bytilting the globe during the insertion of the supports 5. Thereafter, the canopy is dropped down into place with its bottom edge contacting with the flange 7 of the bowl and is subsequently given a partial rotation, for example, to the position shown in Figure 2. This moves the notches 14: out of registry with the link and locks the flat upper portion 12' of the canopy beneath the shoulders of the link formed by the inturned portions, thus precluding any possible detachment of the canopyand holding the canopy locked down upon the globe.

It will be seen that an extremely simple lighting fixture has been provided which is very cheap to manufacture, and which may be manipulated even by an unskilled operator to readily secure a globe in place.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

I claim:

A lighting fixture comprising a lamp socket having a head projecting upwardly therefrom and provided with a.pair of diametrically opposed apertures, a suspension link having an open end provided with a pair of inturned ends promoting into said apertures and providing shoulders on their undersides, means secured to said lamp tially rotated and locked beneath the said socket for supporting a globe, and a canopy shoulders of the inturned ends of said link. adapted to bear against said globe when in In testimony that I claim the foregoing supported position, said canopy having a I have hereunto set my hand at Milwaukee, central aperture to receive said head and in the county of Milwaukee and State of having a pair of diametrically opposed Wisconsin.

notches through which the inturned ends may pass, whereby said canopy may be par- PETER W. SPRECHER.
