Specification of Letters Patent. Patented Nov, 1917.

Application 113-211 January 27, 1917. Serial Nd; 144,892.

722 all whom c't may concern:

Be it known that I, Grocer. B. Tum/res, a citizen of the United States oi. America, and residing at Bridgeport, in. the county of Fai'rfield end State of Connecticut, have invented certain new and useful Inrprovefollowing is specification.

- My invention relates to electrical receptacles: and aricularly to molding recephides, the ojcct of my invention being to provide a compact, readily manufactured and efficient molding receptacle adapted to plates receive attachment plugs of the jack blade t" e. i

l eferring to the accompanying drawings,

Fi e l is e perspective of a receptacle in-w ich my inventiiiin is embodied in one form;

F'g. 2 is a perspective of the receptacle with its base and cover plate detached;

Fig. 3 is en. inverted plan of the receptacle showing it associated with molding;

F ig. 4 is a longitudinal section on the line k -4, Fig. 3;

F ig. 5 is a transverse section on the line 5-5, Fig. 4; and

Fig. 6 is a partial section showing a detail.

In the form here shown the present receptacle comprises a base 16, and cover plate 11, both of insulating material and of generally rectangular shape. The base 10 is longitudinally channeled on its lower face at 12 to receive the wires 13 and 1% leading to the terminals 15 and 16 mounted upon the base- The latter is pierced at 17' and 18 to permit the bored loopsof the wires to be carried up from the channel 12 to the binding screws 19 and 20 which are accessible from the outer face of the bas after the latter has been installed. The terminal 15 and 16 lie on depressed ledgesi21 and 22 in the outer face of the base, to which the holes 17'ahd 18 open and from "which lead channels 23 and 24; openingthrough one "side of the receptacle;

Within thesechainnels lie plug recei ing terminalsfldiand 26,

the oflset bases of which are riy'eted to upstanding flanges 27 end 28 it the terminal.

plates 15 and 16 respectively. The cover plate 11 i which o i' erlies and: incloses these,- ponductors on the outer face, of the base is rovided, with corresponding channels 29 and 30 which register with the channels 23 and 24 on the base end afiford guidaways 'for J the entering jacks of an attuchment plug. In order to reinforce the cover at this point and afford a seat for the plug, a boss til may be provided against which portion of the plug body abuts in the insertedposition of the jacks.

The installation shown in Figs. 3, 4 and 5 represents the position of the receptacle W en the latter is arranged in a line which ntends beyond the receptacle. If the line terminates at the receptacle the wires would be brought in through the channel 32 which lies at right angles to the channel 12 and communicates therewith. At each end of the channel 12 and at the outer end of channel 32, an inset shoulder 33 is formed to afford an abutment for theend of the molding 34. The wires are thus completely housed and there is no danger of their exposure to accidental injury or, contact.

The base 10' is secured to its support by screws passing through the diagonally opposite corners of the base and with their heads seated against the ledges 35 surrouncL ing the screw holes 36. so

The cover is secured n on the base by means of screw bolts 37 whlch take into nuts permanently fastened in the base inregister with the holes 38. .Thi s .may be acc0m lished in the manner indicated in Fig. 6.

he hole 38 for the screw bolt 37 communicates with a well 39 of greater diameter opening from the lower face of the base and having at its bottom a rectangular recess in which the square nut 40 is held against rotation and in alinemcnt with the hole 38, The retaining guardthimble which holds the nut'in its recess has a tubular body 41 closed at one end 42 and provideduat its otherend with a flange 43 which overlies the margins of the nut and is seated in the bottom of thewell 40. On filling the well 39*.with wax, the latter holds the guard in position while the thimble in turn not only revents the wax from entering the threaded liole in the nut but affords withinits tubular body 41 a clearance forthe end of the bolt- 37 which screws through the nut. In orderrois into the lower face of the body lfland havminals connected screws 19 and 20 the plug-receiving terminails 25 and 26 are broughtinto the wire circuit and it is only necessary to insert the plug jacks-"into contact with these terminals to ta 3 the current therefrom through the plug an its associated conductors to the point of utilization;

Various modifications of shape and construction will readily occur to those skilled in the art which do not depart from what I claim as my invention.
