-character, embodying novel means whereby the same may be adjustably secured for swinging movement on the outlet box to permit the switch to be properly positioned with respect to the ceiling fixture should the outlet box be disposed slightly out of horizontal position.

Another important object of the invention is to provide a switch of thecharacter described, having adjustable means on the lower end for connection with the ceiling fixture, whereby the device may be expeditiously secured to various types of fixtures.

Other objects of the invention are to provide a fixture switch which will be simple in construction, strong, durable, efficient in its use, and which may be manufactured at low cost.

All of the foregoing'and still further obiects and advantages of the invention may become apparent from a study of the follow ing specification, taken in connection with the accompanyingv drawings, wherein like characters of reference designate corresponding parts throughout the several views, and wherein: I

Figure 1 is a view in vertical section, showing a switch constructed in accordance with this invention, connected to an outlet box and disposed in position in a ceiling fixture, and connected to said ceilingfixture.

Figure 2 is a top plan view of .the device per se.

Figure 3 is a detail sectional view of the upper portion of the switch housing, showing the means for adjustable connection with oint is provided,

upper portion of the switch housing, which is connected with the outlet box.

Referring to the drawings in detail, it will be seen that the reference numeral 1 designates a conventional outlet box that is se cured to the studs in a ceiling, in the usual manner, and has formed centrally thereon the depending externally threaded neck 2.

The reference numeral 3 designates a conventional ceiling fixture having a plurality of sockets i for the reception of electric light bulbs, thefixture 3 being further provided with a centrally disposed opening in substantially vertical alignment with the neck 2 of the outlet ing this invention comprises a housing desig nated generally by the reference numeral 5 and comprising the threadedly connected up per and lower sections 6 and 7 respectively.

The upper section 6 has formed integrally thereon an upstanding flange 7 having an an cuate inner periphery in which is seated the internally threaded annulus 8, which is adapted to be threaded on the neck 2 of the outlet box 1. The outer periphery of the annulus 8 is, of course, curved to conform to the curvature of the inner periphery of the flange 7. In this manner a universal which permits the housing 5 to be swung to tive to the outlet box 1. The annulus 8 fits tightly in the flange 7 to frictionally prevent idle swinging movement of the housing 5, relative to the outlet box 1. The lower end of the section 7 of the housing 5 therefrom the internally threaded neck 9, havingthe internal flange 10 in its upper end portion. An internally and externally threaded nipple 11 is threaded for adjustment vertically in the neck 9, and is provided with an internal flange 12 at its upper end. An externally threaded nipple 13 is threaded for adjustment in the nipple 11 and is adapted to project through an opening 95 box 1. The switch constitut- 65 any desired position rela- 30 has depending with an opening in registry with the bore of m the outlet box.

the nipple 13. A pull switch 15 is secured Figure 4 is a detail view in elevation of the in a suitable manner in the housing 5 and has connected there to the pull chain 16, which passes through the neck 9, the nipples 11 and 13 and the nut 14, in the manner clearly illustrated in Figure 1 of the drawings. The upper section 6 of the housing 5 has formed therein a plurality of openings 17 for the passage of conductor wires.

It will thus be seen that I have provided a switch construction which may be expeditiously positioned in a ceiling fixture and connected to an outlet box.

The frictional contact between the annulus 8 and the flanges 7 is strong enough to prevent rotation of the annulus relative to the housing, when it is desired to attach the housing to the neck 2 of the outlet box 1. As before explained, the universal joint provided by the annulus S and flange 7, will permit the housing 5 to be constructed as desired, relative to the outlet box 1, and to position the switch properly relative to the fixture 3 and the opening therein through which the nipple 13 projects. The nut 9 and the member 11 and 13 adapt the device for use on ceiling fixtures of different depths. The nut 14 is threaded onto the nipple 13 until the flange 18 on said neck abuts the lower end of the nipple 13 and said nipple 13 will then be caused to rotate and move upwardly into the nipple 11 until the nut 14 engages the fixture 3. If the fixture 3 is of less depth than that illustrated in Figure 3 of the drawings, the nipple 13 may be threaded upwardly in the nipple 11 until the upper end of said nipple 13 abuts the flange 12 on the interior of the nipple l1 and rotary movement will thus be imparted to the nipple 11, in unison with the nipple 13. The nipple 11 is thus threaded upwardly in the nut 9 for engaging the nut 14 with the fixture. The flange 1O limits the upward movement of the nipple 11 in the neck 9.

It will thus be seen that the device constituting this invention provides means for expeditiously clamping the fixture 3 tightly against the ceiling. It will further be seen that the device is adapted, as before ex plained, for use on fixtures of various depths.

It is believed that the many advantages of a switch constructed in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction may be had, which will fall within the scope of the invention as claimed.
