Among the principalobjectswhichthepresent invention has in view are: To provide a simple and eicient corner connection for moldings of the character mentioned; to facilitate the operation of'installing said moldings; and to unify the construction elements employed in said molding. l
Figure l -is la vertical elevation partly in section to show the corner connection constructed and employed in the present invention, and a movable connector plug.
Figure 2 is a sectiontaken as on the line 2-2 in Figure 1.
f Figure 3 is a section taken as on the lineY 3-3 in Figure 1. Y
Figure 4 is a section taken as on the line\ 4--4-in Figure 3.
Figure 5 is a'bottom plan view showing a horizontal corner connection constructed and arranged in accordance with the present invention.
F-igurel 6 is a section taken as on theline 6-6 in Figure 5.' The present invention is more especnly an improvement of the construction disclosed in an application for patent iled by me under date of May 29, 1930, and bearing Serial No. .456,941, forA improvement which application cross reference is made.
In the drawing, a wall molding is permanently installed. The purpose as discl in former applications of form of molding, is to install the molding permanently on all of the walls of a room, preferablyadjacent the baseboard thereof, and to provide in connection therewith, extension members ada ted to receive in service, connecting plugs oft e usual construction for supplying current to lighting bulbs or operating motors.
With'the above stated purpose in mind, the permanent mol ing consists of a metal channel member 11. The member- 1 1 is preferably rectangular in shape and the channel formed thereby preferably opens downward. The channels are partially iilled with strips of insulating material forming a base 12 in which4 is sunk in open metal electric conductors 13`plus and 13 minus. At suitable locations, fasteners such as screws 14 are inserted in moldings, to posi V20 to any Ywithdrawn from the channel by pulling the into the standing structure passing through the channel and the base 12. The conductors 13 plus and 13 minus are electrically connected at the corners of `the structure by means of metal jumpers 15, the one registering with .the conductors 13 plus and the other with the conductors 13 minus, through the medium of yielding contact members 16. The jumpers 15 are embedded in channels 17 as is shown best in Fig. Llof the'drawing, andthe connectors 16 are electrically connected with the jumpers 15 through the compression springs 18. The springs.18 normally eX- tend the contact members so that when in line with the conductors 13 plus and 13 minus they are forced into firm metallic contact therewith. The channels 18 are cut in the face of solid corner blocks 19 which are constructed of any suitable insulating material. The blocks 19 are shaped to suit the installation in which they are to be used, forming sh guIar obtuse or rounded corners,
' rectan the channels 17 and the jumpers 15 being shaped accordingly.v
It will'be noted by reference to Figure 1 of the drawing that on verticalcorners, it is found expedient to have the opening of the channelmembers'll open'outwardly. Inthis 'tion the molding will accommodate the movable plug receivers 20 as is shown by Vbroken in said Figure 1.
The receivers 20 are preferably constructed of insulating material and have installed therein contact members 16 and com rsion springs 18 and blade receptacles 21 w ich are connected by wire laid in the receivers, Awith the springs 18 or in etal b ases 22 therefor.
When provided with a construction such as described, it is desired to move the receiver point in the molding,`the receiver is receivers downward, the contact members 16 being drawn out of contact with the conduc-` tors 13 plus and 13 minus, the springs 18 yielding to permit this; The receiver being thus disengaged from one position is installed in any position at the desire of the operator. l The installation of the receiver 20 in service is accomplished by forcing the said receiver upward into the channel until-the contact members 16 contact with the conductors 13 plus and 13 minus.
I claim: 1. A molding as characterized comprising a relatively fiat elongated insulator base, electrical conductors longitudinally dlsposed with respect to said base and exposed at the front thereof, and a metallic covering for said base and insulators, said covering having its n longitudinal front wall spaced from the said conductors roviding therewith a continuous channel andJ said channel being downwardly open with the opening of constant width for receiving and holding'removable connectors ,s at any desired longitudinal position.
2. A molding as characterized comprising a relatively flat elongated insulatory base, electrical conductors longitudinally disposed with respect to said base and exposed at the 20 front thereof, and a metallic covering for said base and insulators, said covering having its longitudinal front wall spaced from the said conductors providing therewith a continuous channel and said channel being downwardly open with the opening of constant width for receivin and holding removable conductors at any esired longitudinal position, and a connector havin a reduced end portion insertable upwardlggf into said channel and havin spring contact members projecting lateral y from the connector and engageable with said conductors automatically upon insertion of the connector into the channel.
