BOWL-SUPPORTING MEANS FOR LIGHTING FIXTURES.

Application filed October 10, 1925. serial No. 61,637.

My invention relates to the art-of illumination, and particularly to means for supporting bowls used in connection with fixtures, principally electrically operated fixtures, and has for its object to produce such aineans in a simple, strong, durable, and practically inexpensive, construction, which may be easily and quickly operated to secure the bowl to, or release it from, theiixture.

A further object is to produce such a means as will be practically concealed from view, and will not detractfrom the graceful, symmetrical, and beautifying, character of the fixture.

My invention consists of the details of construction hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Fig. l shows a side elevation view of a fixture equipped with my in'iproved bowlsupporting. means; 1

Fig. II shows a vertical sectional view, taken on the line 2-2 of Fig.1;

Fig. III shows a detail view of my supporting rod or wire; and v .Fig. IV shows a detail view of afragment of a bowl, disclosing'the recess formation I place therein.

Referring to the accompanying drawings, the reference numeral 10 is used to indicate a bowl designed to be secured to a lighting ,fixture, 11 tho'lamp. bulb, 12 the cone, or

shell, surrounding the socket which supports the lamp, 13. the reflector which is sometimes used in ligl'iting fixtures, and 1d the .rod, or wire, supports, by means of which the bowl 10 is secured to the fixture. These supports, lei, and; their novel formation, together with the recess formations in the bowl, and the slot and orifice, or recess, formation in the .cone, constitute my invention.

The howl 10, which is 'ireferably formed ofglass, is provided. with two, or more, grooves, slots or recesses, 15, pressed into the upper portion (commonly called the lip), the base of said groove 15 having a relatively sharp angle at its outer extremity. Obviously, these grooves are evenly spaced and arranged around the bowl, and when only two are used they are spaced at directly opposite points in the lip of the bowl.

The support 14 is, preferably, formednof a stilf strand of wire, and a hook, 16, is formed at its base, and this hook is off-set at a desirable angle from the main body portion of the support. In advance of the hooklfi .l have formed a depending shoulder 17, the inturned end of the hook and the end of the shoulder being designed to beon a substantially horizontal plane in relation to each other when the support is functioning to securethe bowl to the fixture. The hook end and shoulder of the support let are designed to be received by, and countersunk in, the groove 15..

The upper end of the support l l also terminates in a hook, 18, which enters cone 12 through a slot,or orifice, 19, ofsubstantially the same width asthe wire l i, and is anchored in an orifice, 20, directly below, and in a vertical plane with, the orifice 19.

The grooveslo in the bowl 10 function to keep the supporting wires 1 1- in proper, and permanent, spaced relation around the bowl, and, as will be hereinafter explained, to form walls extending upwardly from the" lip to which the hook'16 is clamped when the support is drawn toward the center for attaching to the fixture; Also, the grooves provide for practically concealing the sup porting wires from view, so as not to mar the appearance of the regular upper surface of the bowl.

-In practical operation, the lower hook 16 is placed in itsgroove 15, the inturned end of the hook seating itself below the material formingthe base of the groove. The support 1a is-then moved inwardly from this seating until the shoulder 17 abuts against the material forn'iing the base ofthe groove-(but on the upper side thereof). The walls of the groove (the hook being, as stated, countersul'ik in the groove), serve to anchor the support, firmly, against sidewise movement. I

The hook 18 is inserted through the slo 19 in the cone 12, then drops downwardly, its inturned end entering, and being anchored in,lthe orifice '20. As the" orifices 19 and 2d are in: a substantially vertical line,

and are each of only such diameter as to per mit the hook to pass there-through, it is apparent the support 1% must remain in a vertical posit on in one direction though i extending outwardly from the cone to the bowl to which it 1s secured, as described.

This construction supportsthe bowl in a true horizontal plane and functions perfectly for that purpose, even though only two supports may be employed.

tend entirely through the lip of the bowl, although I have chosen this means of illustration. It would be suflicient if a groove, 0r slot, were formed in the bowl to receive the hook 16, in such manner that the inturned end of the hook would engage and overlap material in the bowl, and an angle in the base of the groove be formed to receive the shoulder 17, the construction being such that when the shoulder is engaging the material of the bowl, the inturned end of the hook is firmly seated below material forming the base of the slot.

It is also not essential to have orifices in the cone, as the formation of a recess in the cone to receive the hook member 18, and to firmly anchor it to the cone, would be sufiicient, if the groove were so formed, and would so receive the hook member 18, as'to provide against lateral movement of the support l+l, and thus hold the support in a true vertical position.

The principal function of the recesses and grooves in the bowl, and in the cone, in addition to providing anchoring means for their respective books, is to provide walls, spaced just sutliciently to receive the supporting hooks, thereby causing these walls to function to provide against lateral movement of the support, when the support has been placed therein, thereby insuring the true horizontal positioning of the bowl with relation to the fixture.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:

1. A bowl supporting means for lighting fixtures, comprising a plurality of supporting members formed with hooks on each end; a shoulder on the lower hook, faced toward the inturned end of the hook;

grooves in the bowl to receive the lower' hooked members of the supports; means to attach the upper hooks to the fixture.

2. A bowl supporting means for lighting fixtures, comprising a plurality of support members formed with hooks on each end; a shoulder on the lower hook, faced toward the inturned end of the hook; grooves in the bowl to receive the lower hooked members of the supports; means to attach the upper hooks to the fixture, this means providing against lateral movement of the support.

3. A supporting means for bowls for lighting fixtures, comprising recesses formed in the bowl in its upper surface, there being spaced walls 'to such recesses; means in said recesses to receive a hook; a support with a hook formed on each end thereof, the lower hook being designed to enter one of said recesses in the bowl; a shoulder on the support, facing the inturned end of the hook, and so arranged as to engage the material in the bowl when the hook is seated in the recess; a hook on the upper end of the support; means to secure the upper hook to the lighting fixture.

4-. A supporting means for bowls for lighting fixtures, comprising recesses formed in the bowl in its upper surface, there bein spaced walls to such recesses; means in sai recesses to receive ahook; it support with a hook formed on each end thereof, the lower hook being designed to enter one of said recesses in the bowl; a shoulder on the support, facing the inturned end of the lower hook, and so arranged as to engage the mate rial in the bowl when the hook is seated in the rece s; a hook on the upper end ol the support, means to secure the upper hook to the lighting fixture, said means providing against lateral movement of the support when the hook has been seated in the fixture.

A howl supporting means for lighting fixtures, comprising recesses formed in the bowl in its lip, said recesses being formed with spaced walls, and adapted to receive and anchor a supporting member; means to secure supporting members in said recesses, and means to attach the opposite ends of the supporting members to the lighting fixture, suistantially as shown and described.

6. A bowl supporting means for lighting fixtures, comprising recesses formed in the bowl evenly spaced and arranged around the lip of the bowl, said rcces.:es being formed with spaced walls, and adapted to receive and anchor a supporting member; meansto secure supporting members in said recesses, and means to attach the opposite ends oi the supporting members to the lighting fixture, substantially as shown and described.
