-March 15, 1949. w. J. PARSONS PLUG REMOVER AND THE LIKE Filed Sept. 28, 1945 IN VEN TOR. WAYNE J. PARSONS A TTOR/VEY Patented Mar. 15, 1949 u'mreo PLUG Removers LIKE Wayne iv. rashes, his Kettles, cant. apparent semester 2s, f9245-,-se'iia1N6.'s1e;2rs r calms. (c1. it'sist) This invention relates to means and ways for easily removing electrical plug attachments from wall socketsand the like. So far as known, there is no easy and convenient means available "in which to remove electrical plugs unless the plug is yanked out by grabbing its connected electrical cord or wires. Some attachment plugs are provided with extensions, grab hooks, etc., but such means make the plug more awkward to handle and also make it much too large and bulky for some uses. This invention does not inake any change whatever in the attachment plug itself, but rather combines with the wall receptacle'a means for easily removing the attachment :plug by merely pressing upon a simple push button. Such animprovement in the art, would be a great help to ironers, cleaners, "cook's 'arid'others who must during numerous times during theday disconnect tlie attachment plug from the wall or lamp receptacle.

One of the principal objects of this invention is to present a new and novel attachment plug remover that is simple and sturdy in construction, and which is economical to make and manufacture.

Another object is to provide wall and other types of attachment plug receptacles with a convenient and easy operable push button means for removing attachment plugs and the like.

Other objects, advantages and features of my invention will appear from the accompanying drawings, the subjoined detailed description, the preamble of these specifications and the appended claims.

Applicant is about to illustrate and describe one of the forms of his invention in order to teach one how to make and use the same, but it is to be understood that the drawings and description thereof are not to limit the invention in any sense whatsoever, except as limited by the appended claims.

In the drawings:

Fig. l is a front elevational view of a wall receptacle adapted to receive and make electrical connection with the typical and common two pin attachment plug,

Fig. 2 is a sectional view taken substantially along the line 2-2 of Fig. 1,

Fig. 3 is a view similar to that shown in Fig. but showing the attachment plug raised and ready for easy manual removal,

Fig. 4 is a sectional view taken substantially along the line 4--4 of Fig. 3,

Fig. 5 is a horizontal view taken substantially along line 55 of Fig. 3.

The reference numeral I indicates a wall plate of the typical siz'eand configuration which is pro-'- vided with oval shaped screw holes 2 that receive suitablescrews for firmly fixing the plate directly onto a wall section "of a building and the like, and this plate also has attachment plug pin openings I "and l. The plate carries upon the rear side thereof 'a box '3 having the -five sides 4, 5, 6, 1 and '8, *as shown, which provide a chamber 9 that houses the working parts of the device. The rec'eptacle plate I and the walls 4 to '8 of the box may be one integral piece with a removable back portion, but in this particular showing, the box is attached to the plate in any suitable manner. Cement may be used when the box and plate made of some ceramic 'or plastic material, or soldered or spot welded when some metallic material is employed.

Within the boxel'iamber 9,-there is a receptacle it) having the screws to receive the wires and which is of the usual construction for such purposes, that is, constructed to receive the two pin type attachment plug II that is electrically connected to the two wire cord indicated at l2 in Fig. 2, but a slight change is made in the typical receptacle between its pin attachment parts, which change is to provide a passage or tunnel portion [3 to accommodate the push arm I4 which is reciprocable at the end of the rockable beam IS. The bottom end of the arm being connected to the beam by a pin l6 which rides in a slotted portion ll of the beam. The top of the push arm is rigidly connected to a cross arm 18 which works between the two pins of the attachment plug so as to push the plug upwardly when the beam i5 is tilted in a certain manner.

The beam is pivoted at I9, as by a pin, to a depending bracket 20 that is rigidly fixed to the underside of the plate I, and to continually urge the beam end at H downwardly, a wire type spring 2| is provided and arranged as shown. A button 22 passes through an opening 23 in the plate and has its button portion provided with a bracket that supports a pivot pin 24 that rides in the slot 25 of the beam l5.

From the foregoing construction, it should be clear that the attachment plug ll, regardless of the number of pins fixed thereto, is easily removed entirely from the receptacle ill or just enough so that the plug can be easily lifted therefrom by merely pressing upon the button 22.

It is, of course, understood that various changes and modifications may be made in the details of form, style, design and construction of the whole or any part of the specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the limitations clearly expressed in the following claims.

Having thus described my invention, what is claimed as new and desired to be secured by Letters Patent is:

1. In an electrical device adapted to receive removable attachment plugs and the like, a casing having a plate means at one side thereof, a receptacle for receiving male attachment plugs having the major body portion thereof Within the casing and a portion thereof passing through the plate means to present an exposed face, a pair of spaced apart electrical connections means in the receptacle adapted to receive a pair of pins from an attachment plug, a reciprocable arm passing through the receptacle with means at the exterior end thereof for engaging an attachment plug, a push button passing through the plate means, and a pivoted beam within the easing having one end connected with the arm and the other end connected with the push button.

2. The device recited in claim 1 wherein the arm is positioned between the pair of pin re ceiving connection means and has a bar fixed to the exposed end thereof, and spring means attached to the beam to urge the button in a protruded exposed position when not forceably pressed.

3. In a wall type flush electrical receptacle comprising a casing with an opening at one side thereof covered by a removable plate, a pin type receiving socket fixed to the underside of the plate beneath an opening means therein and another opening means in the plate with a reciprocable button therein, a bore in the socket which opens through the plate, a slot in the socket at right angles to the bore, a lever pivoted at its central point and within the casing and having the button pivoted to one end thereof and a push rod pivoted at the other end thereof which is reciprocable in the bore of the socket, and spring means for constantly urging the button end of the lever toward the plate.

4. In a flush wall type electrical receptacle adapted to make connection with a removable cord type attachment plug, the receptable including a cover plate having opening means at one portion thereof adapted to pass the pins of an attachment plug and for accommodating a push rod and another opening means at another portion thereof for accommodating a push button, an electrical socket fixed to the underside of the plate and having opening means in registration with the first mentioned opening means in the plate with one of these openings having a push rod therein, a push button in said another opening means, a lever having its central portion pivoted to the underside of the plate with one end thereof pivoted to the push rod and the other end thereof pivoted to the push button, and spring means for constantly urging the push button end of the lever toward the plate.
