TERMINAL FOR ELECTRICAL IVIOLDINGS.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed. May 9, 1906. Serial No. 315,948.

To aZZ whom/ it may concern.-

Be it known that I, REUBEN SIMON, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Terminal for Electrical Moldings, of which the following is a full, clear, and exact description.

My invention relates to electric moldings, my more particular object being to produce an improved terminal for use in connection with moldings employed in buildings.

Among the several objects sought to be attained by the use of my improved terminal are the following: first, to eliminate all chance of abrasion in the wiring coverings when in the act of being threaded through the molding or of being removed from the same; second, to secure the capping of a molding more firmly in' position, thus virtually conferring upon this capping a greater degree of strength; third, to improve the insulation afiorded by the molding, and more particularly by its terminal portions; fourth, to improve the appearance of the moldings.

In many instances the capping of a molding is not built to stand the slightest strain, and when displaced or torn away from its fastening the capping allows the wires to come out of the molding. This frequently causes danger to life and property, owing to I the liability of the current making its escape.

In swinging fixtures the abrasion of the wires is exceedingly difficult to prevent, even if the wire coverings be of the best quality that is to say, when a swinging fixture moves back and forth the wires as they come out of the molding are also moved back and forth by the movement of the fixtures, and thus the wires rub against the edges of the molding. Inasmuch as this molding usually presents a ragged edge, the wire coverings are unduly abraded, and the liability of a short circuit is greatly increased. Again, by the swinging movement of the fixture the strain upon the capping is frequently increased, and this sometimes results in causing the wires to fall. Even in cases where the actual increase in danger is not very great patrons raise objection to the use of moldings which might possibly let the wires fall or which might cause a short circuit, and the objections of such patrons are of material detriment to the progress in this art.

In my invention the terminal constitutes within itself a retainer for the cappings, an

insulator for the wire, and also serves as a bushing for the molding, thus preventing abrasion. The terminals may be made of any suitable 'substanceflsucli as glazed porcelain, and are therefore so constructed as to exclude moisture.

Reference is to be had to l-the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts inall the figures.

Figure 1 is a fragmentary side elevation of a molding provided with my improved terminal, certain portions of the molding and terminal being broken away. Fig. 2 is a vertical section upon thelline 2 2 of' Fig. l1,'showing the manner of securing the terminal in position upon the molding. Fig. 3 is a vertical section upon the line 3 3 of Fig. 1, showing the construction of the main body portion of the terminal. Fig. 4 is a horizontalsection upon the line 4. 4 of Fig. 1 looking in the direction of the arrow and showing generally how the terminal is fitted relatively to the molding; and Fig. 5 is a fragmentary section showing a slightly different form of terminal, in which the nozzle is turned substantially to a right angle relatively to the general plane through the terminal.

The molding 6 may be of wood and is provided with channels 7, separated from each other by a partition 8, the latter'being preferably integral with the molding 6, as indicated in Figs. 2 and 4. The molding 6 is provided with bevels 9. The terminal is shown at 10 and is provided with channels 11, ada ted to register with the channels 7 when tfie terminal is brought into registry with the molding, as indicated in Fig. 4. The channels 11 are separated by a partition 12, which is rounded off at 12" and which does not extend quite to the end of the terminal 10. The latter is provided with a constricted and rounded portion 10 or, in other words, is slightly contracted? This is for the purpose of causing the wires to bear off a little relatively to the general inner surface of the terminal. This arrangement and the concave rounding of the part 12 (see Fig. 1) greatly lessens the chance for the wire covering to be abraded as the wire is threaded through or as the wire may be caused to move relatively to the terminal. The body portion of the terminal 10 is provided with a backwardly-projecting tongue 10 which is sunken into the lower surface of the molding 6, as indicated in Fig. 1, and is flush with the bottom of the channels 7, so as to present a smooth unbroken surface along which the wires may glide. The terminal is provided with bevels 13, which register with the bevels 9 of the molding.

In the form shown. in Fig. 5 the terminal 14: is provided with a rearwardly-projecting tongue 15, integral. therewith, and is also provided with two channels 16, one of which is shown, each bent at a right angle, as indicated. These channels are separated by a partition 17, which is rounded and slightly eoncaved, as indicated in the lower portion of Fig. 5. The tip 14 of the terminal 14 is rounded. also like the edge of a drinking-cup. By having the ti. 1.0 or 14 contracted as compared with tie general diameter of the channels and by having the partition 12 rounded at 12 and somewhat shorter than the main body of the terminal the maximum of freedom is allowed for movement of the wires without drawing the same into engage ment with any surface which might prove injurious to them. A screw 18 passes through the tongue 10 or and secures the terminal firmly in position on the molding.

Having thus described my invention, 1: claim as new and desire to secure by Letters Patent- 1. The combination of a molding provided with channels, a body portion of insulating material having channels adapted to register with said channels of said molding, said body portion being further provided with a con.- stricted edge, the latter being rounded for preventing abrasion of wires, and means tor connecting said body portion with said molding.

2. The combination of a molding provided with a plurality of channels separated by a partition, said molding being partly cut away, and a body member of insulating material provided with channels registering with those of said'molding, and further provided with a tongue fitting against said molding where the latter'is cut away,

The combination. of a molding provided with channels and with a partition, and a body portion of insulating material provided with a tongue integral therewith and fitting said molding and said partition, said body portion being further provided with channels registering with those of said molding, and also provided with a partition registering with said partition of said molding.

4. As an article of manufacture, a terminal for electrical moldings, comprising a body portion of insulating material provided with channels separated by a partition, said partition being comparatively short, so as to retreat lrom one edge of said body portion, said edge of said body portion being constricted and also being rounded to prevent the abrasion of wires.

5. The combination of a molding which is cut away for a little distance, and a body portion oi insulating material fitting against said molding and provided with a tongue iitting into the mutilation thus formed by cutting away said molding, said body portion of insulating material and said molding being provided with channels in registry with each other.

6. The combination of a molding pro vidcd with channels and with a mutilation, a body portion provided with. channels registering with said channels of said molding and further provided with a tongue entering said mutilation, and means for securing said body portion and said molding rigidly together.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

REUBEN SIMON.
