Description

June 23,1949. E. w. HARRIS v 2,474,356
ELECTRICAL DISTRIBUTION JACK Filed Aug. 19, 1946 Inventor Erizesi 11V. Harrisa Patented June 28, 1949 'OFFlCE'I This invention relates to electric connectors" andimore particularly to connector'r'attachmentsr for I usefin' connection withr the illumination of Christmas trees.
The invention has for its main object to provide a simple and effective attachment, which may serve as a distributing connector for many electric connections and which may be fixed to the tree without specific fixation means.
A further object of the invention consists in providing a connector attachment which effects a substantially radial distribution of the connection wires leading to the lamp bulb and which permits concealment of the attachment and of the wires radiating therefrom.
A further object of the invention consists in providing a connector attachment which is easy to manufacture and which has to be provided only in a limited number of sizes to fit all the trees to be decorated.
Further objects are explained below in connection with a more detailed description of the invention.
One embodiment of the invention is illustrated in the accompanying drawing. It is however, to be understood that this embodiment is to be regarded as an example serving as a base for the explanation and description of the invention. With the aid of this specific embodiment the invention is described in such terms as to enable the expert skilled in this art to construct or design other desired modifications of the same. Such modifications as foreshadowed in the specification and covered by the annexed claim are therefore not to be regarded as departure from the invention.
In the drawing:
Figure l is a plan view,
Figure 2 is an elevational side view, partly in section of the tree illuminating outfit,
Figure 3 is a section through the connector on an enlarged scale, and
Figure 4 is a part of a side view showing an extension receptacle.
The illumination of a tree, such as a Christmas tree, by means of a large number of light bulbs presents certain difiiculties on account of the large number of connections which have to be made with the main lines or the power circuits of the house. As such an illumination serves decorative purposes and as the outline or appearance of the tree should not be impaired, the electrical connections have to be concealed as far as possible. While it is easily possible to conceal the radially running wires and a few isolated plug 1 Claim. (01. ire-seer connections, @transver'se wires, boxes forj "large numberiof connections andother equipment are conspicudus and are cifii'cu1t to mcunt ona =tr'e of relatively smalusizi Moreover; "tn e brancriing off of a large number of wires or cords from a single point causes a congestion which is unsightly.
The invention therefore, provides a multiple connector which distributes the connections radially along a stretch of sufficient length and facilitates mounting without the use of fixation means which are damaging, such as nails or screws, permits easy change of the location, and concealment of the connector attachment, and allows an essentially radial spreading of the connecting wires or cables so that these wires may not interfere with the decorative appearance.
To achieve these results the attachment consists of a rubber connector 5 of horseshoe form of a substantially rectangular cross-section (Fig. 3) which encircles the trunk of the tree and which adapts itself automatically to every size of the trunk, within certain limits attaching itself firmly to the trunk in any position which may be selected without special attachment or fixation means. The attachment may be easily concealed below a branching point for the branches of a tree or below some other decoration.
The outer or radially directed face l2 of the connector attachment is formed by a rubber strip provided with two rows 6, 1 of connection jacks 8, 9 each jack arranged for making connection with a single wire plug IE or it. Preferably one supply or feed wire H], II respectively, connects all the jacks 8 or 9 respectively, of a row, so that the two plugs l 5, I 6 of a connecting wire I8 leading to a bulb 20 or to a series of bulbs have to be inserted into adjacent jacks of the two rows. If desired, the distance of the two rows 6, 1 may be so chosen that double plugs may be used for connection wires bridging the two rows, but single plugs seen to be preferable as connections are more flexible and are more easily concealed. A feed plug and cord I3 is arranged which supplies the two feed wires I0, I i with current. Moreover, an extension receptacle I4 is arranged which is preferably of the usual double plug type so that an extension cord IQ of the usual type may be plugged in. This receptacle l4 may be used in connection with the feed plug of another connector attachment of the same or another type, to be used in the event that further lamp circuits have to be fed.
In order to facilitate the mounting of the electrical connections the outer or radially directed face 12 of the rubber connector may consist of a carrier body holding in a detachable manner a separate sheet 2| carrying all the electrical connections. For this purpose the sheet may be inserted behind suitable ears 22 and edges 23 of the main body of the attachment.
It will be noted that the horseshoe connector attachment permits a perfect radial distribution of the connections either all around the tree or around that portion of the entire periphery which is usually decorated and presents itself to the spectator.
By using two or more attachments clamped to the tree at diiferent heights, all the connection wires may be placed radially along branches and twigs thus permitting to secure the desired decorative effect.
Minor changes of the details will not change the basic idea of the invention as claimed.
I claim:
A connector attachment for electric light bulbs to be attached to a tree, comprising a hollow horseshoe shaped body of rubber, a separate rubber sheet forming the outer side of said horseshoe REFERENCES CITED The following references are of record in the file of this patent:
