BOWL HOLDING MEANS FOR LIGHTING FIXTURES April 8, 1930.

My invention relate to the art of illumination and particularly to lighting fixtures employing a reflector and diffusion bowl, and has for its object to provide a simple, strong,

;, durable, inexpensive and adequate, means for holding the bowl in proper position to the re-- fiector.

A further object is to provide such a means in a construction that will permitof the bowl in being easily and quickly attached or detached from the fixture. I

This invention is a modification of the invention disclosed in my Patent No. 1,663,653, issued to me by the United States on the 27th 15 day of March, 1928.

My invention consists of certain details of construction hereinafter set forth, pointed out in my claim and illustrated in the accompanying drawings in which,

reflector adapted for use in my construction;

Fig. 2 shows a side elevation View, partially in section, of a reflector, bowl, and my bowl holding means; and.

end elevation of the spring-actuated bowlholding clip.

Referring to the accompanying drawings the reference numeral 10 is'used to indicate a reflector, preferably substantially flat on its reflecting surface, and the numeral 11 indicates a bowl to be attached to the reflector; The bowl I employ is of the usual type with a lip 12 moulded on its upper extremity, the lip flaring outwardly asshown. Obviously the openingat the upper part of the bowl is circular in conformation. The numerals 13, 1e and 15 indicate bowl holding clips or lugs, the clips 13 and 1a being rigidlyaflixed to the 49 under surface of reflector and having downwardly and 'nwardly projecting body portions as shown. i r

The clip 15 is preferably U -shaped'in conformation and spring-actuated, and: extends from a yieldable contact with the globe 11,

outwardly to the side of the reflector 10, thence curves upwardly and rearwardly, passing through the orifice 17 in the reflector 10 and terminating in a shaft 18, provided with a pin 20, the shaft passing through an orifice in a bracket 22 rigidly afiixed to the upper surface of the reflector 10. 'A coil spring 21 surrounds the shaft 18, its outer end abutting against the inner surface o-f-the bracket 22', and-its other end abutting against 4 a pin 20 secured to the shaft 18, as shown.

The construction of the clip 15, and its mounting as described, is such that the clip is normally held at its inner position by the tension of the spring 21, but can be forced, in a slidable motion, longitudinally, outwardly, against the compression of the spring.

In practical operation a bowl 11 being deto the reflector 10, the lip of the bowl is inserted between the lower surface of the reflector and the clip 15. Pressure is then put upon the bowl to force the clip 15 outwardly until the bowl has reached a position where the lip will be permitted to come in complete contact with the lower surface of the reflector, it having passed the points where the lugs 13 and 1 1 would interfere with this. The bowl is then moved until the lip is flush with the reflector and the pressure on V the bowl is then removed, the tension of the spring being sufficient to force the clip'15 inwardly thereby seating the lip of the bowl between the clips 13 and 14: and the under surface of the reflector.

tion, and I except as limiting the scope of my invention, by the appended claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is In a device of the character described, the 5 combination, with a reflector and a bowl having a lip formed thereon, of a plurality of fixed lugs secured to the reflector to engage the lip of said bowl, there being an opening in the side of said reflector, a spring-actuated 1o shaft mounted on the upper side of the reflector, the end of said shaft extending outwardl'y through said opening, thence downwardly and inwardly and forming a retaining clip, and having a spring mounted to hold said clip 15 normally in engagement with said lip.
