FIXTURE HANGER.

Application filed August 18, 1925.` Serial No. 51,056.

My inventionv relates to fixture hangers and particularly to a novel type of fixture hanger which is adapted to support electric light fixtures.

t is 'the' object of my invention to provide a hanger which may be suitablymounted in the ceilingof a display room and in which an electric light fixture may be supported.

In such a fixture hanger, it is my object to provide parts which will, with the hanging of an electric fixture, provide electrical contact with a source of current so that the lights in the fixture may be lighted by operating a switch in the hanger.

The construction which it is my object to provide is particularly adapted for use in display rooms and it furnishes a means of lighting the fixtures independently so that each may be displayed by itself, and each be lighted with a minimum wastage of electrical power.

It will further be found that where al display room is equipped with hangers made in accordance with my invention the installation of new fixtures and the interchanging of fixtures with relation to each other will be greatly facilitated.

Referring to the drawing in which I'have illustrated a preferred construction:

Figure 1 is a perspective view of a hanger hook.

Figure 2 is a side elevation of the hook without the connecting wires.

Figure 3 is a section along the line 3, 3 in Figure 2.

Figure 4 is a longitudinal vertical section of my preferred type of insulation bar.

Figure 5 is a perspective view of the hanger assembly.

Generally indicated at 1 is the hook member to which a fixturefmafy be secured. The hook has a lower shank portion 2 which preferably is both internally and externally' threaded so that more than one type of fixture may be supported in the hook member without the necessity of using additional bushings and couplings for each different type of fixture. The hook member has a hook portion 3 with fiat sides on which are disposed strips of insulation 4 and contact plates Screws 6 may be utilized to retain the insulating and contact plates on the sides of the hook portion. All screws in the hook member are insulated from each other, (as indicated at 7) so that they will not short circuit in the hook member. Electric wires vthe ring wit-h screws, projecting through 8 are connectedto the conta-ct plates as shown vby the heads 9 of the screws.

Fixtures of any desired types which are not illustrated as they form no part of my ,60 invention, may be suitably assembled on the hook members prior to hanging. The convenience of being able to connect the xtures with contact plates which connect with an outlet box forming part of the supporting structure will bel apparent when it is considered that the old wa'y Ofhanging fixtures required the connecting of the wires from the lights in the fixtures with sources of current in the ceiling while the person connecting the fixture was standing on a ladder. With my type of hook no ladders are required excepting in so far as the hanger may be sufficiently high up to require a ladder to elevate the fixture to a properly suspended position.

The construction of the parts which make up the supporting structure comprises a member which may be attached in the ceiling, and a rigid member on which spring clips in a circuit are mounted, vwhich is sufficiently strong to support a desired fixture.

` In the illustration l have shown the ceiling engaging member in the form of a ring 10 with a fianged lower portion 11 in which a hole 12 provides space for inserting the hook member. The ring is provided with a cross member 13 suitably mounted in the sides of holes in the ring, and is provided with one round hole 14 in the center of the cross member and an oblong hole 14a on each side of the round hole. The round hole in this member is adapted to be used when the hanger is installed where attachment is made to an outlet box already in the ceiling or wall, and the oblong holes are adapted to be used with screws when the hanger is attached to the ceiling or wall. VExtending' across the ring is a rod 15 of insulating material which may ne suitably mounted in the sides of the ring with screws, projecting through the holes in the ring. The rod has disposed on its outer surface a pair of conductive spring clips 16 which are secured to the rod and extend toward opposite sides of the rod and the clips have their adjacent ends 17 bent over and sufficiently interspaced from each other so that the Contact plates on the hook member will engage theends and establish electric contact with the clips. One of the clips is connected with the negative, neutral or ground lead line of an electric circuit as indicated and the other is connected With a switch 18 which is provided in the hanger. 'lhe switch may be suitably secured to the sides of the ring, and as Will be readily understood, the switch is connected With a positive or live lead line by Which current may be supplied to the fixture.

Modifications otl structure ivill readilyoccur to those skilled in the art Without departing from the principle ofl my invention herein disclosed.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent, is: y

l. A fixture hanger comprising in combination with a mounting; member having a rod vof insulating material mounted on the member, spring contacts disposed on the rod, the spring contacts connected with a source of current, and a fixture engaging member with insulated hook shaped conductive plates thereon adapted t0 be connected with lights in the iixture, and the engaging member adapted to hook on the rod With the conductive plates in contact with the spring contacts.

2. A separable outlet for electric fixtures embodying a hooked fixture engaging member with conductive plates on the outer sides of the member adapted to be connected With lights in a fixture, a supporting member adapted to be retained on a Wall, interspaced spring contacts and arod of insulationniaterial in the supporting member Vsupporting the spring contacts, and the plates adapted to engage the contacts with the hook member suspended from the rod.
