ELECTRIC LAMP HOLDER v Filed Feb. 19, 1955 INVENTOR Patented Oct. 29, 1935 UNITED STATES PATENT OFFICE Elliott Clemence, Millburn, N. r. Application February 19, 1935, Serial No. 1,211

8 Claims.

This invention relates to a holder or support that is especially adapted for supporting the individual lamps of a string of Christmas tree lamps upon the limbs of trees or the like.

In carrying out the invention a resilient support is attached to the husk of each lamp in such a way that the support is very rigidly and securely attached to the husk. The supports are adapted for attaching the lamp to limbs or other objects of diflerent sizes and will hold the lamps in upright or other positions on the limbs as desired.

The invention will be understood from the description in connection with the accompanying drawing in which Fig. 1 is a side view.of an illustrative embodiment of the invention Fig. 2 is a similar view taken at-rlght angles to Fig. 1; Fig. 3 is a plan view looking at the lower end of the device and Fig. 4 is a side view of a modification oi the supporting member.

In the drawing-reference character I indicates a husk for an. electric light socket, this husk being made of insulating material, such, for example, as phenol-formaldehyde condensation product, well known as bakelite. The husk I is approximately cylindrical in shape, but tapers slightly in a downward direction. It is open at its upper end I to receive a lamp bulb and contains a screw shell and center contact (not shown) of the well known sort for receiving and making electrical connection to the lamp bulb. The center contact and screw shell are in turn connected to contacts at the bottomof the husk I, to which contacts opposite wires 8 and 4 of line wires may be soldered after stripping oil the insulation 6 for short distances along the wires. The cap I is forced on to the lower reduced end of the husk I to aid in keeping the wires 8 and 4 in place, slots 8 being provided on opposite sides of the flange oi the cap I for this purpose. The parts thus far described are old and well known.

The enlarged lug or extension I II is provided on the outside of the husk I near its open end. A longitudinally extending slot II is provided in the lug It with its lower end open and its upper end closed. The bottom of the slot I I is substantially flush with the outside surface of the husk I and the sides of this slot are dove-tail shaped with the wider part nearest the surface of the liusk, as most clearly shown in Fig. 3. 1

YA clip or holder I2 has a central fastening extension I 8 which is inserted into the slot II from the lower open end. Teeth I4 are provided on opposite edges of the extension I8. These teeth slope downwardly and the extension I3 is of such 9, width that the teeth I4 cut grooves along the sides of the slot II. As the holder is forced into place from below into the slot II It will be securely retained in place due tolthe fact that any attempt to withdraw the holder in the other direc- 8 tion causes the ends of the sloping teeth I4 to dig into the sides of the slot II and prevent withdrawal. The dove-tail shaped edges of this slot prevent withdrawal perpendicularly to the husk.

Acircumferentially extending portion I of the holder I2 lies snugly against the outside surface of the husk I. Arms I6 01' the holder I2 extend at right angles to the portion I! from the ends thereof and also rest against the husk I. Goose neck bends I? are provided at the upper ends of is the arms I8, and spring arms I8 extend from the goose neck bends I1 and are preferably made of zig-zag or angular shape in a longitudinal direction. An integral extension It extends from the cen- 2o ter .of the lower edge of the portion ii of the 'holder I2 parallel to the axis of the husk and therefore diverges slightly therefrom, as shown in Fig. 2. The end of the extension I 9 may be bent inwardly under the end of the husk.

With a row of lights, such as Christmas tree lights, for example, connected to a pair of wires in the usual way, the individual lights can be attached to limbs of different sizes simply by hooking the arms I8 over the limbs and exerting slight pressure, whereupon the limb will enter between the arms I8 and the extensions I9 the proper distance to cause the lamps to be held in whatever positions they are placed.

The holder 2| shown in Fig. 4 has a toothed 85 fastening extension 22 corresponding to the extension I3 in the other figures. A single spring arm or clip 23 is connected to the extension 22 by means of a gradual or goose neck bend 24 so as to avoid the danger of the same being broken by fiexure. A reverse bend 25 is provided near the end of the arm 23 to enable the lights to be readily fastened upon or hooked over a limb of a tree in an upside-down position when desired. while retaining the possibility of hanging the 4 lights upon limbs in upright positions with the limb between the portions 28 and the husk to which the holder is attached.

I claim:

1. In an electriclight holder, -a husk of insulating material, an integral lug along one side thereof having a slot with an open side therein substantially parallel to the axis of said husk and a support having an extension frictionally secured in said slot.

121 11; an electric light holder, a husk oi. in- 'sulating material, an integral lug along one side thereof having a slot therein substantially parallel to the axis oi said husk anda support having an extension frictionally secured in said slot, said extension having teeth engaging the side walls oi said slot.

3. In an electric light holder, a husk 01' insulating material, an integral lug along one side thereof having a dove-tail slot therein substantially parallel to the axis of said husk and a support having] an extension projectinginto said slot and secured therein by friction;

4. In an electric light holder, 8. husk of insulating material, an integral lug along one sidethereof having a slot therein substantially paral-.

lel to the axis of said husk and a support having an extension irictionally secured in said slot, said support being provided with a spring arm.

theredi; having a' slot therein substantially parallel-to the axis of said husk and asupport having an extension frictionally secured in said slot, said support being provided with a pair oi. spring arms on opposite sides of said extension.

ELLIOTT CLEMENCE.
