LIGHT EXTENSION.

Application filed June 4, 1924. Serial No. 1113861.

This invention relates to an electric light extension, and it consists in the novel featnres hereinafter described and claimed.

An object of the invention 1s to prov de means for extending the wire, which connects with the electric light fixture or other electric fixture, so that the wire may be wound up when it is desired to set the light or fixture back, whereby. the slack in the wires will be takenup, and they will not be in the way.

With the above object in view, the extension includes a spring actuated drum ournalled for rotation in a casing, with the wires arranged to wind thereon, there'being provided a brake mechanism for holding the drum against rotation, and means for releasing'the brake mechanism, in order that the wires may rewind upon the drum.

1n the accompanying drawings:

Figure 1 is an elevation with the casing in section of the light extension.

Figure 2 is a horizontal longitudinal section of the same.

Figure 3 is a transverse sectional View thereof, out on the line 3-3 of Figure 1.

Figure 1 is a transverse sectional view, at the end portion of the casing of the light extension.

Figure 5 is a detail perspective view of a lever used in the light extension.

The light extension comprises a casing 1, which is mounted upon a plate 2. Brackets 3 are housed within the casing 1, and are attachedto the main plate 2. Wires 4 lead into the intermediate portion of the plate 2, and pass transversely through the brackets 3. The wires are connected with binding posts 4. which are carried by levers 5, fulcrumed upon lugs 6, mounted upon the brackets 3. Springs 7 hear at their inner ends against the brackets 3, and at their outer ends against the inner edges of the levers 5, and serve to resiliently hold the lower portions of the levers toward the brackets 3. One bracket 3 carries a bearing 8* and a bolt 9 is journaled in the bearing.

11 bushing 30 is mounted in the member 8 carried in the other bracket 3. A. bolt 9 projects through the bushing 30. The inner ends of the binding post 1, bear against the outer ends of the bolts 9 and 9*. Wires 10 are connected with the inner ends of the bolts 9 and 9 and brought together and passed through the side of a drum 11, which is mounted upon the bolts 9 and 9*. 1he periphery of the drum 11 is provided with a spirally disposed groove 12. Brackets 13 are also mounted upon the plate2, and a shaft ltis carried by the brackets 13. A disc 15 is loosely journalled upon the shaft 1 1: andv may move longitudinally thereof. The disc 15 is provided with a convex end portion 16, which enters the groove 12 of the drum' 1'1, and a concaved end portion 17, which is adapted to bear against the convolutions of the wires 10 as they are wound upon the drum 11, and seated in the groove 12 thereof. The casing 1 is provided with alongitudinally disposed slot 18, through which the wires 10 pass after they leave the drum 11. A. spring 19 is connected at one end with one of the brackets 3, and connected at its other end through screw. 8' and bolt 9 with the drum, whereby the wire 10 may be rewound upon the drum, when the drum is released, as hereinafter explained. A disc 20 is fixed to one end of the drum, and a shoe 21 bears upon theperiphery of the disc 20. The shoe 21 is carried by a spring arm 22, which is pivoted to a bracket 21' on the plate 2, and a helical spring 23 is connected at one end with the arm 22, and at its other end with the side of the casing 1. The spring 23 is under tension with a tendency to normally hold the shoe 21 in frictional contact with the periphery of the disc 20. A chain 24 is connected at one end with the free end portion of the arm-22 and is passed through one ofthe brackets 3, and passes through the bottom of the casing 1, as best shown in Figure 1 of the drawings. When the chain 21 is pulled, the free end of the arm 22 is raised, whereby the shoe 21 is lifted above the disc 20, and the drum 11 is released and may rotate under the influence of the spring 19, whereby the wires 10 are wound upon the drum and are guided in'positien in the groove thereof, by Y the disc 15.

When the chain 24 is released, the arm 22 descends. and the shoe 21 is brought into frictional contact with the periphery of the disc 20, whereby the drum 11 is held against rotation, and the wires 10 are maintained in wound condition upon the drum.

When the wires 10 are pulled, they are unwound from the drum. 11, and the disc 20 slipped upon the shoe ,21. The light or the electric fixture is connected withthewire 10, and consequently it will be seen that an extension device of simple and durable structure has been provided for taking up the slack in the Wire and for providing an efiicient electric connection between the source of electric supply and the electric fixture.

Having described the invention, What is claimed is:

1. A light extension device of the class described including, in combination, a plate, a casing mounted on the plate to depend therefrom, a pair of brackets housed Within the casing in spaced relation to each other, a pair of levers, one pivoted on each bracket to the outer side thereof, terminals carried by the levers, bearings mounted in the brackets, bolts journaled in the bearings, springs engaged with the levers to normally hold the terminals engaged with the bolts, a drum rotatable on the bolts, and means insulating the drum from the bolts.

2. A light extension device of the class described including, in combination, a plate, a casing mounted on the plate to depend therefrom, a pair of brackets housed within the casing in spaced relation to each other, a pair of levers, one pivoted on each bracket to the outer side thereof, terminals carried by the levers, bearings mounted in the brackets, bolts journaled in the bearings,

springs engaged with the levers to normally hold the terminals engaged with the bolts, a drum rotatable on the bolts, and means insulating the drum from the bolts, said drum being provided with a spiral groove, brackets depending from the plate, a shaft carried by the last mentioned brackets, a disk loosely journaled upon the shaft for rotary and sliding longitudinal movement thereon, said disk being provided with a convex edge portion for entering the groove of the drum, and a concave edge portion for bearing against the convolutions of a Wire windable on the drum.

3. A light extension device of the class described including, in combination, :1 casing, a drum journaled in the casing and provided with a spiral groove, a shaft mounted in the casing and parallel to the axis of the drum, a disk slidable and rotatable on the shaft, said disk being provided With a convex edge portion adapted to project into the groove of the drum, and a concave portion for bearing against the convolutions of a Wire windable on the drum.

In testimony whereof I aflix my si nature.
