UNITED STATES PATENT- OFFICE.
TOOL.
ap lication filed October 19, 1926. serial in. 142,772."
This invention relates to new and useful improvements in electrical appliances, and particularly to devices for manipulating screw plugs.
The principal object of the invention is to provide a tool by means of which a screw plug may be easily'screwed into the socket of a light fixture on which fixture'is mounted a shade of such diameter that the operator cannot insert the hand to. manipulate the plug into or out of the socket.
Another object is to provide a device of this character which is adapted to remain applied to the plug, so that application or removal of the plug, ,with relation to the socket is facilitated and danger ofthe tool bein lost obviated.
Ot er objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.
In the drawing:
Figure 1 is an elevation of the device applied to a plug, the plug beingengaged in a socket, and the shade being shown in section.
Figure 2 is a perspective view of the tool, removed from the plug, and the parts of the plug shown in position to be engaged with,
the tOOl.
Figure 3 is a horizontal sectional view on the line 3-3 of Figure 1.
Referring particularly to the accompanying drawing, 10 represents an electric light socket, and 11 the narrow, elongated shade attached thereto. Screwed into'the socket is the two-part plug 12, the lower part 12 of which is provided with the prongs 13 for engagement in the usual apertures in the upper part of the plug, such apertures being well known, and not illustrated. Connected to the removable part 12, of the plug, is the electric cord 14.
The'tool is formed from a single piece of stiff fiber, or other suitable insulation material, and comprises the tapering stem 15, on
the wider end of which is formed the right angularly extending circular portion 16, said portion being formed with an elongated 50 opening 17 through which protrude the before-mentioned prongs 13, of the removable section of the plug, said prongs .being so fitted into said opening that relative iotary movement of the plug part and the tool are prevented. on the lower, or narrower end of the stem there is formed a smaller elongated portion 18, which extends at right angles to said end, and is arranged in parallel relation to the portion 16. This smaller portion 18 is formed with a key-holev opening 19 through whichthe electric cord 14 passes. It will be noted that the circular portion 16 is of greater diameter than the screw plug, so that it projects a sufficient distance therebeyond to prevent breakage of the plug should the latter be dropped, by contacting with a floor ,before the body of the plug will strike the same.
In the use of the tool, the operator inserts the ends of the electric cord through the opening 19, and then properly connects the ends of the wires of the cord to the lower part 12, of the plug. The tool is then slipped upwardly on the cord into such position that it may be moved down and the prongs 13 engage through the opening 17. The prongs are then inserted in the apertures of the upper partof the plug, so that the circular portion 16 is clamped betweenthe portions of the plug. The operator then grasps the smaller end of the tool, inserts the tool and plug upwardly into the shade, and screws the 'pluginto the socket. The walls of the opening 17 engage with the prongs so that when the tool is turned the entire plug is forced to rotate, thereby fa-' cilitating the screwing or unscrewing of the plug. Furthermore, the stem of the tool is of such length that the operator can readily maintain the proper grip on the smaller end tllie'reof while applying or removing the p ug. 1
What is claimed is:
1. A tool, for manipulating a two-part electric screw plug, one part of the plug having prongs, comprising a stem having a disk extending angularly from one end thereof and adapted to be disposed between the parts of the plug and having an angular opening snugly receiving the said prongs therethrough to permit rotation of the plug upon rotation of the tool, and an apertured handle on the other end of the stem receiving an electric cord therein.
2. As'an article of manufacture, a twopart electric screw plugmanipulator comprising a stem, an apertured disk on one end of the stem extending at right angles therefrom, and a, handle portion on the other end ofthe stem extending in parallel relation'to the disk and-having a. notch opening through one side thereof.
In testimony whereof, I eflixmy signa'-- ture.
