WALL MOUNTED ELECTRIC OUTLET Filed March 3, 1950 Inventor! Attorneys Patented Oct. 7, 1952 WALL MOUNTED ELECTRIC OUTLET V Irenee Brouillette, Montreal, Quebec, Application March 3, 1950, Serial No, 147,550

v"I'hepresen-t invention relates to an electric outlet and more particularly to an electric outlet of the type which is removable aifixable to a wall, partition and the like as an electrical extension from a stationary wall receptacle.

It; is known that breakage of electrical appliances, such as lamps and the, like, is a commonoccurrence in homes and other living quarters: due to the fact that such electrical ap pliances are very often directly connected to a wall receptacle resulting in accidental tripping and pulling of their electric cords and landing of the electrical appliances on the floor. is especially true when such appliances are This placed ontables, desks and like pieces of furniture.

Accordingly, the general object of the present, invention is the provision of an electric outlet which is designed to overcome the above mentioned defects.

'More particularly the main object, according to the present invention, is the provision of an electric outlet which is readily and removably amxable to a partition or a piece of furniture without in any way aifecting the esthetic value of the same.

Another important object, according to the present invention, is the-provision of an electric outlet which is readily and removably afiixable to a partition, wall andthe like, and yet will not be accidentally removed.

Another important object, according to the present invention, is the provision of an elec-- tric outlet of the character described, the outside face of which will project only slightly from the outside face of the partition to which it is afiixed.

Still another important object, according to the present invention, is the provision of an electric outlet which is affixable to partitions of various thicknesses. I

' The foregoing and other important objects according to the present invention will become more apparent during the following disclosure and by referring to the drawings in which:

Figure 1 is a perspective view of a desk provided with electric outlets according to the present invention;

Figure 2 is an elevation of the electric outlet aifixed to a partition shown in cross-section;

Figure 3 is an exploded cross-section along line 3-3 of Figure 2;

Figure 4 is a detailed cross-section of one of the elements shown in Figure 3;

Figure 5 is a cross-section along line 5--5 of Figure 3; and

4 Claims. (01. 173-4330) Figure 6 is a fractional, perspective view of the rear portioncf the main body according to theinvention.

Referring now moreparticularly to the drawings in which like reference characters indicate like elements throughout, the Figure 1 shows an application of the electric outlet according to the invention, in which a desk A is provided with the outlets of the invention indicated at B, s aid outlet being electrically connected by means of the cord C to a wall receptable D. A lamp E is shown directly connected to one of the outlets B according to the invention.

The outlet 3 comprises a cylindrical main body l made of insulating material and provided at one end with a flange 2 and at the other end with an extension 3 of smaller diameter.

The main body 1 and extension 3 are threaded on the-outside to' receive respectively a hexagonal'nut 4 and the coupling 5 retaining the cap housing 6.

The main body I is provided with two spaced bores 1 of rectangular cross-section and opening at the outside face of the flange 2 and being in communication at their inner end with circular holes 8 which open at the outer face of the extension 3.

The bores 1 house two contact prongs 9 of standard construction, said prongs being secured to the main body I by means of bolts I0 and nuts II, the former extending through holes8. i

The bolts 10 also secure to the outer face of the extension 3 the resilient contacts l2 which are separated by means of the elongated integral projection l3 formed diametrallyat said outer face.

The coupling 5 has" inner threads M for screwing tothe extension 3 to enclose the same and press the screw contacts l5 mounted on the flange I6 of the cap housing 6 against the resilient contacts I2. I i

It is to be'noted that the cap housing 6 is provided with a diametral recess 11 formed in the flange l6 to engage the projection [3 of the extension 3 for positioning the cap housing in such a manner that each screw contact l5 will be opposite a resilient contact H2. The cap housing 6 is rotatively inserted into the central aperture 8 of the coupling 5.

The cap housing 6 is apertured at [9 on one side thereof to receive the electrical conductor C, the two strands 20 of which are individually connected to the screw contacts l5. Each of said screw contacts l5 engages a suitable metallic insert 2| embedded into the flange I8.

It is to be noted that the conductor C will not.

be twisted during the attachment of the housing cap 6 to the main body I, because-said'housin cap 6 will be retained in position byrneans of th projection I3 of the extension 3 during the screwing-on operation of the coupling-5.

Because the extension 3 is of a smaller .diameter than the main body I, there is defined at the intersection of the two,,an inclined abutting portion 22 adapted to act as a stop for the coupling 5. Thus said coupling5 maybe screwed on tight in. order to prevent its accidental. re-

moval without causing the screw' contacts l5, to

exercise an undue pressure on the resilient contacts l2. g

It' is .seen that the device, according'tothe present invention, will benearly flush witllthe side wall or partitionv to which it isafllxed' and will not affect the esthetic value of the same; it is readily and securely affixed to a wall and nevertheless will not be-removed accidentally by children.

While a preferred embodiment. accordingto the present invention'has beenv illustrated .and

described, it is understood that-various modificaand .abutting said shoulders, resilient contacts K disposed at the other end of said body, electrical connectors extendingwithin said restrictedportion of said bores and securing saidjprongs and resilient contacts together and tosaidbody, a cap housing,'e1ectrical contacts mounted on'said housing, a threaded coupling affixable to said body in threadedengagement, said last mentionedelectrical contacts abutting said resilient contacts when said housing is'secured to said body bymeans of said coupling."

2. An electric outlet as claimed 'in claim 1 wherein said housing is adapted to come into abutting contact with said body, an integral outwardly projecting diametral bar extending at said end of said body, said housing having a diametral recess formed at its contact end and adapted to engage said bar, said housing so constructed and arranged so as to be positioned thereby upon screwing said coupling.

3.. An. electric outlet. comprising a solid cylindrical body threaded on the outside, said body made of insulating material and adapted to be inserted into a hole of a partition, an outwardly extending flange at one end of said body, a nut engaging said threads for securing said body to said partition, a cylindrical extension integrally and axially dependent from said body of smaller diameter than the latter and threaded on the outside, a peripheral shoulder formed at the intersection of said body and said extension, said body having axially extending spaced bores of rectangularcross-section, opening at said end, said extension having axially extending circular holes opening at the outer 'end thereof and respectivelycommunicating with said bores, con tact prongs disposed entirely within said bores, resilient contacts disposed at the outer end of said extension, bolts extending through said holes and respectively securing said prongs to said resilient contacts, a cap housing, electric contacts secured to said housing on one face thereof and adapted to be electrically connected to a source of electric power, a coupling member adapted to threadedly engage said extension, said 'cap housing rotativ'ely inserted in said coupling, the last mentioned electrical contacts adapted to abut said resilient contacts, said shoulder acting'as a stop-for said coupling member whereby the latter may be screwed tight without causingan undue pressure on .said resilient contacts.

4'. An electric-outlet asclaimed in claim 3, an integral outwardly projecting diametral bar extending at said outer end face of said extension, said housing having a diametral recess formed at its contact end and adapted to engage said bar, whereby said housing will be positioned by said bar upon screwing said coupling member.
