Referring in detail to the drawing, the embodiment of the invention therein shown comprises a cylindrical tube 11 composed of any substantially hard material such as Bakelite or a fire resistant plastic, such material being either plain white or any other desired color and, where so desired, having candle drippings molded thereon so as r 2,782,296 Patented Feb- 1 5 to impart a realistic appearance. Aifixed upon the said cylindrical tube 11 is a'candle socket 12 having two connecting receptacles 13, 14in itslower portion adapted to receive a pair of prongs 15 16 and hold them firmly in position. It is also to be noted, as shown in Figur'e'4, that the said candle socket 12 fully encases the said receptacles 13, 14, and also receives the lower portion of the aforementioned cylindrical tube 11 so as to provide a rigid support therefor. At the base of the said candle socket 12, there is also located two oppositely positioned

cutouts

17, 18 through which wires 19, carrying suitable insulation 20 may be passed so as to bring a source of electric current within the said socket 12, and to allow an ou le r h i e e the Pu o e o Pretecting these wires 19 against wear at the points where they en er nd le e oc e he e s loc t d a Pai of short, tapered rubber sleeves 21, 22, as illustrated in Figure 6. v

The candle socket 12 hereinabove referred to is also adapted to receive and retain a manually operable clamp 23 having serrated faces 24 engageable with a branch 25 of a Qhristmas tree. The upper portion of the said clamp 23) consists of a short cylinder 25 receivable and retainabie within the base of the candle socket 12 and having cutouts 2d, 27 to match those contained Within the said candle socket 12. The assembly of the aforementioned clamp 23 and candle socket 12 is illustrated in Figures 3 and 40f the drawing.

There also contained within the upper portion 9f the cylindrical tube 11 a bulb socket 218 of conventional screw type design adapted for reception of a candle type bulb 29 with a standard screw type connection 30, As an alternative to this arrangement, a push-pull type of bulb can be manufactured and used in conjunction with a plug-in type socket, this being a more convenient bulb reception arrangement.

The wiring from the said bulb socket 28 may consist of buss wire such as is commonly used in the manufacture of electronic equipment and will comprise a

pair ofwires

31, 32 leading from the bulb socket 28 to the lugs on the soldering disc 33 where they will connect with the above-mentioned

prongs

15, 16. It is to be noted that buss wire is used in this arrangement of the invention so as to impart a substantial degree of rigidity to the unit and thereby prevent any undesirable buckling of the wiring. It would also be well to point out here that where the plug-in type of socket is used, as mentioned above, the wires may be soldered directly to the connections thereon.

Suitable insulation, such as spaghetti should be used to cover the bare buss Wires 31, 32. Moreover, all exposed connections are to be covered with a good fireproof cement. The soldering disc 33 is also to be composed of a nonsconductive material so as to substantially reduce the risk of fire in the vicinity of the Christmas tree.

The electrical connections within the above described unit also include the wiring to and from the receptacles 13, 14 which receive the

prongs

15, 16. These receptacles 13, 14 may consist of a tubing of very small diameter wherein the four wires 19, two of which enter and two of which leave the socket 12, may be tightly clamped instead of soldered, said clamping being efi'ected by a pair of

screws

34, 35. One alternative to this clamping unit consists in using split receptacles to receive the

prongs

15, 16 and in utilizing only two Wires to connect to the

screws

34, 35, as illustrated in Figure 6, these wires having their insulation removed in the vicinity of the said

screws

34, 35 and accomplishing a substantially neater arrangement.

The wiring within the upper portion of the cylindrical tube 11 and its connections with the wire entering and leaving the candle socket 12 are diagrammatically illustrated in Figure 5. In practice, it has been found convenient to use a number of the above described units in conjunction with an outlet cord 56, having a conventional type plug 37, a switch 38, and a plug-in socket 39, as illustrated in Figure 7. Thus a plurality of units may be connected together as shown in Figure and as illustrated diagrammatically in Figures 8 and 9. In Figure 8 the outlet cord 36 is connected by its plug-in socket 39 to a suitable plug 40 which leads to one candle unit and also to a similar plug-in type socket 41 which may be utilized to connect to additional candle units as desired, said additional connections being effected in the same manner. It is to be noted that the candle sockets 12,and the lower portion of the cylindrical tube 11 containing the

prongs

15, 16 are indicated diagrammatically in Figures 8 and 9. Figure 9, however is designed to illustrate more clearly the wiring connections to the various candle units. Thus each individual unit employs a series connection but is arranged in a parallel connection with respect to the main source of current as carried in wires 19.

All of the wiring employed in this invention may be of the conventional variety of wire used in the manufacture of Christmas tree lights, with the exception, however, of the buss wires, as hereinabove described. Miniature or standard size plugs may be used as desired, suitable plug-in type sockets being provided therefor. Where miniature plugs are used, however, an extension cord having one standard size plug and one miniature plugin socket should be used.

With the wiring arrangement described above, it is to be emphasized that, unlike conventional Christmas tree lighting sets, the polarity of the connections of the candle units is immaterial, the units being operable regardless of the polarity of their connections.

The candle units may be manually clamped to branches at various points on the Christmas tree, as illustrated in Figure 1. With the arrangement described hereinabove, it is clear that the risk of damage to light bulbs is materially decreased since the bulbs may be left in their sockets; and due to the convenient arrangement for connecting the various units, entanglement of wires is avoided and the possibility of tripping over portions thereof is minimized. The lights may be mounted quickly and more easily than with conventional type Christmas tree lights and involve no undesirable injury to the appearance of the tree. Moreover, since the unit is away from the inflammable foliage of the Christmas tree, it is substantially safer than conventional units.

Due to the wiring used, damage to one light will not affect the lighting in the remaining units. Furthermore, since the individual units are separable, and operable in any desired number, they may be purchased in any desired quantity and more conveniently stored when not in use. Of course, the utility of the units which are the subject of this invention is not limited to Christmas decoration purposes but may also be used for other types of decoration as well.

The embodiment of the invention illustrated and described hereinabove have been selected for the purpose of clearly setting forth the principles involved. It will be apparent, however, that the present invention is susceptible of being modified in respect to details of construction, combination and arrangement of parts which may be resorted to without departure from the spirit and scope of the invention as claimed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States:
