UNITED STATES PATENT QFFICE LUMINAIRE Henry E. Butler, Scotia, N. Y., assignor to GengrralkElectric Company, a corporation of New Application December 1, 1936, Serial No. 113,636
3 Claims. (01. 240-128) My invention relates to luminaires, particularthat of the collar 1. When the globe and canopy ly to luminaires in which the light source is surare assembled, the canopy is merely placed over rounded bya translucent enclosure consisting of the neck portion 6 of the globe, and moves downseveral parts, and more'particularly to a device wardly until the ring I! engages the magnets 9.
for holding these parts in juxtaposed position. The magnets 9 attract the ring and,. when the 5 One object of my invention is to provide an imring contacts the ends of the vertical pole memproved fastening device between parts of lumibers H and I2, exert sufficient force to hold the naire enclosures, whereby the parts are normally canopy in place against any normal force exertheld together with a sufliciently large force to ed by wind pressures on he other d, if

In accordance with my illustrates an application of my improved device invention, this eak s completely eliminated,

A second ring II The globe 5 is closed by a canopy l3, which of a magnetic material such as soft steel, for excarries a magnetic ring I, sprung into a groove ample, is cemented to the inner surface of the II on the inside of the canopy and above a vercanopy is at the juncture of its annular flange tlcal flange l6, having a diameter greater than 26 and the body portion of the canopy. When 56 netized ring I], the flange 20 covers the neck portion of the globe, and the canopy is inits proper relation to the globe. The advantage of this modified form of my improved device is that it eliminates the use of the supporting ring I, and thereby interferes less with the projection of light through the globe than the device of Fig.1.
In Fig. 4 I have illustrated an application or my invention to a modified form of luminaire in a which a metal canopy 22 is suspended from a ceiling. Canopies of this type are usually made of a non-magnetic metal, such as brass, and
screws are provided projecting radially from the flange to engage a groove, or holes, in the globes. In applying my invention to this type of luminaire, I substitute a magnetized ring 23 similar to the ring ii, for the above mentioned screws and attach a magnetic ring 24, preferably made of soft steel, to the edge of a globe 25. When the magnetic ring 24 is brought into contact with the permanently magnetized member 23 which may be a ring such as ring ll or a series of magnets, such as magnets 9, attached to the canopy, the globe 25 is held in position just as securely as though the well-known screw type of globe holder were used. The removal of the globe 25 and its replacement, are however greatly facilitated since no time is consumed in turning screws. Although I have illustrated my invention as applied to glass enclosures of two different types of luminaires, it will be apparent to those skilled in the art that it is equally adaptable to other forms of luminaires and is also adaptable to any receptacle provided with a cover, which it is desired to hold in closed position by a force greater than that of gravity.
The magnetized member such as the ring I I of Fig. 3 or the magnets 9 of Figs. 1 and 2 may vhe readily built into, and made a part of the cover, or of the receptacle itself. The receptacle and cover need not necessarily be made of glass, but may be made oi other materials such as, for example, any of the synthetic resin materials sold under the trade-marks of Glyptal" or Bake- I 9,147,482 the ring I8 is brought into contact with the ma lite" or others. The magnetic and magnetized member need not necessarily be separate elements of the cover or of the receptacle, since the entire cover, or the receptacle itself may be made of a magnetic material, and may constitute the magnetic element of thedevice. It may not be practical to make the magnetized part of the device as a cover or as a receptacle, but such construction' is not outside of the scope of my invention.
What I claim as new and desire to secure by Letters Patent of the United States is:
1. In a luminaire, the combination of a globe and canopy therefor, a plurality of magnetized elements attached to one of said members and a magnetic element attached to the other of said members, said magnetic element being contiguous to said permanently magnetized elements when said globe and canopy are in assembled relation with each other.
2. In a street lighting luminaire, the combination of a globe and canopy therefor, and means for holding said canopy to said globe comprising a metal ring attached to said globe, a plurality of magnets attached to said ring, and a magnetic ring attached to said canopy and placed contiguous to said magnets when said canopy is in assembled relation with said globe.
3. In a luminaire the combination of a globe provided with an opening at the top, said opening being surrounded by a collar projecting upwardly from the globe surface, a canopy for said globe provided with a flange extending downv said magnetic ring into engagement with said permanently magnetized member and when said ring and member are in juxtaposed position forms a cover therefor.
