Application lei .Tune 11, 1910. SerialNo. 566,361.

To all whom it may concern:

Be it known that I, GEORGE BROOKE, a subject of the King of Grreat Britain, residing at the city of New York, borough of Manhattan, in the county and State of New York, have invented certain new and useful Improvements in Molding Sockets and Plugs, of which the following is a full, clear, and exact specification.

My invention relates to improvements 1n electrical cut-outs, and the same has for its object more particularly to provide a simple, eiticient and reliable receptacle and plug which may bereadily connected to electric conductors disposed within a molding.

Further, said invention has ,for its object to provide a device which may be secured in position, and connected to the conductors without necessitating the cutting or severing of said conductors.

Further, said invention has for its object to 'provide a device which may be readily secured in place between the adjacent or separated ends of molding sections in such manner that the device shall be substantially flush with said molding.

Further, said invention has for its object to provide a socket and plug, and means for completely inclosing the same, which inclosing means shall also serve to secure the plug in position within the socket member of the device.

To the attainment of the aforesaid objects and ends, my invention consists in the novel details of construction, and in the combina- `tion, connection and arrangement of parts hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings forming part of this specification, wherein like numerals of reference indicate like parts, Figure 1 is a side view showing a separated section of electrical molding with a socket and plug constructed according to and embodying my invention applied thereto; Fig. 2 is a face view thereof showing the movable cover portions of the housing separated to disclose the detachable plug 1n position within the socket member; Fig. 3 is a view similar to Fig. 2 with the housing Aand detachable plug removed to show the interior construction of the socket member, and its position relatively to the adjacent ends of the molding sections; Fig. 4 is an inverted plan view of the plug; Fig. 5 is a transverse section taken On the line 5-5 of Fig. 2 looking in the direction of the arrow, and Flg. 6 is a detail longitudinal section oi the plug taken on the line 6-6 of Fig. 4.

In said drawings 10 designates a ceiling or other suitable support to which is secured, in the usual manner, an electric molding comprising two separated

sections

11, 11, provided with the

usual capping strips

12, 12a. Intermediate the separated ends of said molding sections is disposed a socket member 13 made of porcelain, 0r other suitable insulating-material, and corresponding incross-sectional area with the molding sections 11, 11a and the capping strips 12, 122l thereon. The socket member 13 consists of a fiatbase 14 provided along its opposite longitudinalr edges with upwardly extending walls or

side members

15, 15, and at the opposite ends of the base 14 intermediate said side walls or members 15, 1.5 are provided

integral supports

16, 16 having their upper edges flush with the upper edges of the

side walls

15, 15. At the inner edges of the

supports

16, 16 are provided inwardly extending

projections

17, 17

which have their upper edges partly cut away. The intermediate portions of the said walls or members 15, between the

supports

16, 16, are slightly curved longitudinally while their ends are straight and arranged parallel with the longitudinal sides of the

supports

16, 16.

18, 18 denote contact members secured adjacent to the inner ends of the

supports

16, 16. Each of said contact members comprises a base 19 having a vertical transverse side 2O arranged upon the inner transverse side of one of the supports 16,l 16 while the longitudinal vertical side 21, is arranged at at right angles thereto and parallel with the

projections

17, 17 extending from the inner edges of

supports

16, 16. The

contact members

19, 19 are secured in position uponthe base 14 of the socket member by

screws

22, 22 extending. from below, through the base 14 of the socket members and into the

base portions

19, 19 of said contact members. Each contact member 18 is provided at its base with an integral laterally projecting portion 23 having its outer end 24 turned upwardly and arranged in close proximity to the inner side of one of the

walls

13, 13 of the socket member.

24, 24a denote electrical conductors disposed within the longitudinal grooves of the molding and extending through the socket member 13 intermediate the

walls

15, 15 and supports 16, 16 thereof. vThe conductors '24, 24a each have a portion of the insulating' covering removed therefrom at a point directly above one of the transversely extending portions 22, of the Contact members 18, 18, which bared portion is secured to said projection by a screw 25. The

supports

16, 16 are provided with vertical apertures to receive

screws

26, 26 whereby said socket member maybe secured in posi? -adapted to lievintermediate the supports 16, `16, and upon the projections, 17 17 extending therefrom. rlhe plug 27 is 'provided upon its under side with depending longi tudinal projections 29` 29, and adjacent to the opposite ends of said plug are arranged

lugs

30, 30 and extending intermediate the depending longitudinal project-ions and upon

saidlugs

30, 30 are secured

metallic contact members

31, 31, each comprising a top portion 32 from which extend side members 34. The

contact members

31, 31 are 4secured upon the

lugs

30, 30 by screws-33,

33 extendingthrough the top plate 28.

34, 35 denote flexible conductors which are twisted together, and have their inner ends extending through an opening 36 in the center of the plug 27, and secured by

screws

37, 37 to the

contact members

31, 31. The

contact members

31, 31 arranged upon the under side of the plug 27 are slightly staggered in order to conform to and fit intermediate the longitudinal sides of the contact members 18, 18 upon the base 14, and the

projections

17, 17 extending inwardly from the supports 16` 16 on said base.

38 denotes a housing comprising a pair of

longitudinal members

39, 39 adapted for contact with the vertical edges of the

molding sections

11, 11, and the outer side of the

walls

13, 13 of the socket member 13. The upper edges of said longitudinal members are bent outwardly and united at the opposite ends by separated

transverse sections

40, 40. The

longitudinal members

39, 39 are of such height as to fit upon the

molding sections

11, 11, and permit the transverse connecting

sections

40, 40 to contact with the outer sides of the

capping pieces

12, 12, and be secured in position upon said molding sections by

screws

41, 41a. Upon the opposite ends of the housing 38 are arranged

slidable cover plates

41, 41, which have their ends bent over the projecting edges of the

side members

39, 39. The opposing edges ofthe

cover plates

41, 41 are provided with

semi-circular recesses

42, 42 which jointly form a circular opening when the

cover plates

41, 41 are brought together to receive the central boss 43, provided upon the outer side of the plug 27, and through 'which the opening 36 1n the plug 27 also extends.

In order to attach the plug-27, it merely becomes necessary to insert the same within the socket member 13, whereby the

contact members

31, 31 on the side of the plug 27 are -caused to 'engage with the Contact members 18, 18 arranged upon the base of the socket 14, and form electric connections therewith. Thereupon the

cover plates

41, 41 are moved inwardly toward each other until their opposite edges are brought into contact and thereby confine the plug 27 in position within its socket 14.

It will be noted that by means of my improved socket and plug, it merely becomes necessary to cut away a portion of the molding sufiicient to accommodate the socket member 13, and then remove a small portion of the insulating covering of each conductor in order that an electric contact may be established between the conductor and the projections v25, 25 extending from the contact members 18, 18 on the base of the receptacle. Hereupon the

cover plates

41, 41 of the housing 38 are brought together to close the opening in said housing and confine the plug properly in position within its socket member. The opening intermediate the

transverse portions

40, 40 of the housing 38 is of suiticient size to permit of the plug 27 being readily passed therethrough and inserted into the socket member.

It will thu's be obvious by means of my receptacle and plug, connections may bemade at any desired point in the line, and as the socket and plug correspond in cross-sectional area with that ofr the molding and its capping piece, the same will not project beyond the outlines thereof, thus producing substantially flush attachment which is not subject to be disturbed after it has been properly adjusted and securedin place.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

1. The combination of a molding comprising two separated sections, with a socket member disposed intermediate the separated ends of said molding sections, a detachable plug adapted to be fitted into said socketmember, and means on said molding sections adapted to inclose said plug and positively secure the same in positlon within saii socket member, substantially as speci- 2.
