JOHN K. RIDDLE, or TOLEDO, OHIO, ASSIGNOB TO THE EDWARD u. RIDDLE COMPANY, or TOLEDO, OHIO. A

-MOUNTING DEVICE FOR LIGHTING FIXTURES.

f A cation flled October 17, 1923. Serial No. 669,084.

To all whom it may concern: p

Be it known that I, JOHN K. RIDDLE, a citizen of the United States, residin at T0- ledo, in the county of Lucas and tate of Ohio, have invented a certain new and useful Improvement in Mounting Devices for Lighting Fixtures, of which the following is the specification.

My invention relates to the lighting fixture art and particularly to the means applied for securing lighting fixtures to a ceiling, wall, or the like. j i

It is well known that when an outlet box is used, the box is usually provided with a central stud which is externally threaded. A coupling is enerally secured to this stud and then a bio ey also would be employed. On the other hand, Where there is no outlet box, a crowfoot, then a close nipple and then a hickey are sometimes used and unless a slotted hickey is provided, the wires must be threaded through the inside of these fittings. The assembly of such a device requires much time and the manufacture is expensive.

My invention has for its object to completely overcome these objections and provide a device which will be capable of use in whatever condition is presented, so that when a fixture goes out equipped with my improvement, it can be attached to either the outlet box stud or directly to the wall and that without the interposition of conling, nipples, crowfoot or hickeys, and has or its further object to accomplish this result by actual decrease in the expense, besides materially reducin the amount of labor required to install xtures.

My means of accomplishing the foregoing objects are readily seen in t e accompanying drawing which is hereunto annexed and is a part of this specification.

Fig. 1 shows a side elevation partially in section of my device, where it is attached directly to the ceiling and there is no outlet box.

Fig. 2 shows a similar view where an outlet box is mounted in the ceiling.

Fig. 3 is a side elevation; Fig. 4. is a vertical section and Fig. 5 is a plan View.

Figs. 6 and 7 show the use of the device for the mounting of a bracket back on the side wall under both conditions.

The same reference numerals refer to similar parts throughout the entire description.

A SfSIIOWII in the drawings in Fig. 1, my improved mounting device 111 comprises a cylindrical sleeve 9, which is'provid'edwith a plurality of radially extending lugs 11. These lugs are provided with opening 17, through which pass screws 8, when the fixture is to be attached directly to the ceiling or wall, as shown in Figs. 1 and 6. Internal threads 7 are formed in the sleeve 9, adjacent one end and are fitted to threads cut upon the central stud 16 of the outlet box 15. Internal threads 5 are formed adjacent the other end of the cylindrical sleeve 9 and these threads are adapted to receive the fixture supporting rod 13 or the rod 13, which is employed to hold the bracket back 14 to the wall. A canopy 1 1, of the usual construction, surrounds the device when se cured to the ceiling.

A slot 1:2 which extends entirely through the wall of the cylindrical portion 9 is cast or formed in the mounting device adjacent one end and affords a convenient means of insertion of electrical conductors 10. \Vhen the device is to mount a bracket back 011 the side wall, a button 18 is employed on the end of the rod 13 and serves to secure the bracket firmly to the wall.

From the foregoing description, it will be seen that if a fixture is provided with my improved mounting device, if the condition presented is one where an outlet box is provided, the mounting device will fit on to the stud 16 and the fixture can be supported from the rod 13. On. the other hand, if there is no outlet box, then the opening 17 in the lugs 11 furnish means for the insertion of the screws 8, which are screwed into the ceiling or side wall and the fixture can be supported from the supporting rod 13 or attached in the case of bracket back between rod 13' and the button 18. It will also be apparent that there is no necessity for a crowfoot or a coupling or a slotted hickey, since my mounting device provides a combination of all three, thus avoiding the necessity of purchasing these additional 7 parts and also minimizing the expense for vantageous way, as it greatly facilitates the threading of the wires to the fixture.

Having described my invention What I regard as new and Wish to secure by Letters Patent is:

1. An article of manufacture comprising a fixture mounting, a hickey having a central cylindrical tube, a plurality of lugs extending radially from one end of said tube there being a hole through each of said lugs, internal threads in one end of said tube and internal threads in the other end of the tube, two of the lugs being spaced apart and an open slot extending through the Wall of said cylindrical tube between the spaced lugs.

2. The combination with an outlet box of a fixture mounting hickey comprising a central cylindrical tube, having a plurality of lugs extending radially from one end thereof, there being a hole in each of the said lugs; internal threads in each end of said tube adapted to engage threads on an outlet box stud; and two of the lugs being spaced apart and a U shaped slot extending through the Wall of the said tube between the spaced lugs and means for securing the hickey to the outlet box, the said box closing the end of the slot.

Dated Oct. 6, 1923.

JOHN K. RIDDLE.
