oonnnoron son woon To METAL nomme.

To all whom 'it may concern? Be it known that I, HENRY R. GLsoN, residing at Baden, inthe 'county of Beaver and State of Penn'sylva-nia,A a citizen of the United States, have invented or discovered certain new and useful improvements in Connectors for Wood to Metal Molding, of which improvements the following is a,

specileation. y y

ln buildings provided with electrical conductors for lighting, etc., it is frequently desii-able to extend the circuit to various points, as for additional lights. The modern. practice both for economy and safety, is to carry the conductors of the extended circuits ythrough surface ine-tal moldingregardless et the itind of conduits used in the original installation; and, since a large part ot the surface conduits formerly used is wood molding, the circuits are then extended. from Wood to metal molding.

The object ot my invention, which relates to installations of the character described, is to provide a connector adaptt-:d to extend romthe end of a section of metal molding to an adjoining section of Wood molding,

Iand to carry the conductors from one tothe other in a manner complying with all the rconditions of such installation.

lt is a further object oi? my invention to provide a connector that he used to extend circuits both from the end and side of wood moldings to metal moldings. Y

In the accompanying ksheet ci drawings, which forms part of my specifica-tion, l have illustrated the preferred embodiment of my invention, and its application to circuits ex'- tended hoth from the side and ends ot Wood molding.

Figure l is a plan view of a complete installation; Fig. 2 is a longitudinal sectional view takenl on the line II-IL Fig. l; Fig. 3 is a perspective view, to enlarged scale, of connector block alone, showing the top and the end adjacent 1to ythe Wood molding; and Fig. is a similar View of the same block, but showing its betteln and the end adjacent to the metal molding. y

ln the several figures like numerals are used ,to designate like parts.

The Wood molding illustrated herein is of the usual' type comprising a hody portion 1 and a cover 2. The body portion is provided with separated grooves 8, 3 adapted to rey Specification of Letters Patent.

cured to the body portion after the conduc-y tors have been laid in position. TheA metal molding consists of base and cover portions 5 and 6, each semi-elliptical in form, the cover being adapted to snap upon the hase. However, it will be understood that Various other forms of metal molding maybe emA ployed in the same manner as that shown.

In extending a circuit from the wood molding, wherein the conductors are required to be carried in separate grooves, to metal molding, iylxerein the conductors may he side by side. it is nee iry in the completed installation that a partition extend between the conductors until thej,Y enter he metal molding, and in making the installation it is required that the conductors he laidl in placeT rather than drown through any part of the conduit, The connector which l provideis applied after the conductors have been laid in place; it aiords a converging separate. and inclosed path tor each conductor; and protects their 1nsuletion against abrasion by the end edges of the metal molding.

The connector is illustrated particularly inFigs. v3 and 4, and consists oit' aan arch shaped block of insulating material, prefer- Patented Apr. 6, 1915. Application tiled December 12, 1913. Serial No. 806,295. I

iolding to the metal moldingvside of the 'f block. A slot 11, open aty both ends, is 'formed within the tongue, and is provided with a bead -or shoulder 25. The metalmolding end of the block, 'as shown particularly in Fig. 4, is provided with a seat 1'3 against `which the end of the metal molding abuts, thereby preventing the abrasion;

of the conductor insulation by the endedgesI of such molding.

Referring now to the metal molding may be secured, by means of installations wherein 'l theconnector is employed, the hase 5 of the v a. screw 14, to a plate 15, which in turn isat-A tached to a Wall or support by means of a 1 screw 16; and the branch conductors,. '17 and 17, electrically connected to thef.;co;if

dnctors 3 and 3a, may loe laid, in the position 'particularly illustrated in the lowrgleft' hand portion of Fig. 1, that is, converging y from their point of connection to such eon-` ductors. The connectorblock may thenbe secred Vto the plate 15 by means of screws 18 extending one through each hole 26 of the When the connector is placed in position, the conductors 17 and 17 will lie one within each groove of the block, and the metal molding will extend into the 'seat 13. The complete installation of the connector,

legs 8.

` when applied to a circuit extended from the side ofV a Wood molding, is illustrated in the upper left hand portion of Fig. 1; and, inv

addition to the above detailed description,.is

effected bysecuring-'the porcelain cap 19 to vthe c'onnector block' by means of a screw 12 provided with'a nut 28 which engages the shoulder or bead 250i the slot 11,'as seen in Fig. 2. -The capl19 and the splicing block 20,beneath it arel suchas have' been ordinarily used when branch circuits have been carried in Wood molding. They are detailsof construction usually required by the underwriters for splices and similar connections and therefore need not be .described herein. g

When 1t is desired to extend the circuit from 'the end of Wood molding, rather than from the side thereof, the arrangement may be such as is illustrated in the` right hand portion of Fig. 1. The same connector is used in the same manner and for the same purpose in each instance, the only-difference being that in aside yconnection to the` plane-faced .ends of the connector,V legs 8 i (seen particularly in Fig. 3) areadjacent .to

the side of the Wood molding, while inthe endconnection they are adjacent to the end thereof. In the end extension, the cap 19 and splicing `block 20aL are the saine as used heretofore in eifecting a splice in conductors carried in continuous Wood molding, the cap 19a. being attaizhed to .the connector ,by the Shrew, 12 and-to the Wood molding, 2 by a `screw 21, thereby indirectlydattaching the 'connector to the molding.

I claim as my invention: 1'. The combination with `adjoining secfrom the roof thereo legs of said blocka the connector through 'extending to the .ing the connector through tions of woodand metal moldings-carrying electrical' conductors in c1rcuit, of a connector between said sections and at the end of said metal molding, said connector consisting of an arch-shaped`block of insulating material hav` a tongue extending.`

and forming with the pair of conductorre=\ ceiving grooves diverging freni the end of the meta molding, and -mea-ns for attaching said tongue tothe Wood molding. v .i t i 2. Thecombination with adjoining sections of wood and metal moldings carrying i 3. The /combmation with adjoining secv .Il tions of wood and metal moldings carrying electrical conductors in circuit, of a connectorl between said sections and. at the end `of said'` metal molding, 'said .connector consistng of an arch-shaped block 'cat insulat* ing material having a tongue extendingv from the roof thereof `and forming with the legs of .said block a pair Aof conductor-receiving grooves communicating With the end of the metal molding, and means for attachsaid tongue to the Wood molding.
