Specification of Letters Patent.

Patented Jan. 4, 1910.

Application filed September 28, 1906. Serial No. 336,580.

T 0 all whom 'it may concern: Be it known that I, VICTOR BAGLEY, citizen of the United States, residing at Topsham, in the county of Sagadahoc and State of Maine, have invented certain new and useful Improvements in Hangers for Electric Fixtures and the Like, of which the following is a specification.

My invention relates to hangers for electric fixtures such as lights, ceiling fans and the like, and has for its object the provision of means whereby the fixture is readily and effectively secured in a plumb position despite any irregularities in the ceiling at the point of support.

The invention, as hereinafter more'fully described and as particularly setout in the claims, will be readily understood from an inspection of the accompanying drawing, in which a preferred embodiment of the same is shown.

In these drawings Figure 1 is a side elevation of thehanger with a portion of the fixture arranged therein; Fig. 2 is a top plan view of the hanger and its parts; Fig. 8 is a bottom plan View with the fixture in section Fig. 4 is a vertical sectional view through thecoinponent parts of the hanger showing the fixture in position; and Fig. 5 is a detail, showing certain portions of the hanger in aosition on the fixture,

Great diiliculty is experienced in hanging electric ceilin fixtures by reason of the fact that it not infrequently occurs that the ceiling is not level at the point of support or does nbt occupy an exactly horizontal position. '-l,;t becomes necessary in such cases to block up or otherwise modify the relation of the crow foot to the ceiling so as to bring the fixture to a plumb position, a sleeve or collar being used to hide, so far as possible, the inaccuracy of fit and minimize the imperfectionsin the job. Such unsightly mountings of electric fixturcs'are familiar and have been considered aspractically unavoidable. By the present intention these difficulties are entirely obviated.

Referring to the drawings in detail, a crow foot A has the usual upper surface. whether plane or studded. for contact with the ceiling. while the lower projecting portion is coneavoconvex, preferably concave,

on the inside and convex on'the outside. It

is provided with the usual central opening.

a for the retention of the fixture and with a lateral slot (1 to permit the insertion of the fixture B. p

The fixture B is threaded in the usual manner, and bearing nuts I) and b are fitted thereon in threaded engagement. The hearing members or nuts I) I) are provided with opposed -bearing faces. the one being convex to fit the concave surface of the crow foot, and the other being concave to fit the convex surface of the crow foot. The nut 72 might be made integral with the fixture B, the nut I) being adjustable onthe fixture B, a wing I) being provided for turning the same.

The concaveand convex surfaces of the crow foot and the convex and concave bearingsurfaces of the nuts b 7) are in cross section the arcs ofcircles having a common center, whereby the bearing nuts and concave-convex crow foot together form a universal joint for the fixture B and the fit between the parts is perfect ,whatever angle be assumed by the fixture 13 relative to the crow foot A within a wide range.

The manner of applying the hanger is obvious. The crow foot having been secured in any suitable manner to the ceiling, the bearing nut Z) is retracted on the fixture B and the fixture passed through the slot a into the central opening a, and allowed to swing freely with the bearing nut b resting within the concave surface of the crow foot.

'By its own weight the fixture is caused to assume a plumb position, whereupon the bearing nut 72 screwed into position to firmly engage with its concave surface the convex surface of the crow foot A, clamping the crow foot between the two nuts, the bearing nut 7) serving as a check nut.

It is obvious that the concave andconvex bearing surfaces may be reversed and that other minor changes in detail may be made without. departing from the invention as described. is also clear that this hanger is adapted for use in connection with wall brackets as well as ceiling fixtures.

Having'now fully described my invention, what ll claim as new and desire to secure 1) Letters-Patent of the United States is:

' 1. A hanger for electric fixtures and the like. comprising aconcavo-convex crowfoot concave on the inside and convex on the outside and provided with a lateral opening to receive the fixture rod and 'a central opening to retain the same. in combination with an integral fixture rod, a. downwardly con- Ice vex bearin member secured to the end of the rod an fitting within the concave surface of the crowfoot, and an upwardly concave nut threaded upon the same rod as the bearing member and at a distance therefrom and arranged" to fit the convex outer surface of the crowfoot and to clamp the crowfoot between the nut and bearing member.

2. A hanger for plumbing electric fixtures and the like, comprising a concavo-convex crowfoot concave on the inside and convex on the outside and provided with a lateral opening to receive the fixture rod and a central opening to retain the same, the concave and convex surfaces being formed as arcs of circles having substantially the same center, an integral fixture rod, a downwardly convex bearingmembersecured to the end of the integral fixture rod and fitting within the concave surface of the crow foot, and an upwardly concave nut threaded jipon the fixture at a distance from the convex bearing member and arranged to fit the convex sur-' face of thecrowfoot and to clamp the crowe foot between the nut and the bearing member.

In testimony whereof I afiix my signature
