WIRING DEVICE Filed Oct. 1, 1936 INVENTO Patented Mar. 1, 1938 UNITED STATES PATENT OFFICE Application October 1,

4 Claims.

My invention relates to wiring devices. The usual convenience outlets provided in homes and other buildings to supply current for the operation of portable electric appliances and equipment are commonly built into the walls where their use is attended by considerable inconvenience when it is desired to operate equipment at a distance from the walls. Moreover, such outlets are ordinarily placed in the base boards adjacent the floor where they are poorly located for supplying current to appliances intended to be oprated on tables or other platforms at table height, such aselectric cooking appliances, sad irons, etc. However located, there is commonly an inadequate number of such outlets provided.

It is a principal object of my invention, therefore, to provide as a new article of manufacture an improved portable extension device of sturdy construction and light weight having a plurality of auxiliary convenience outlets supported at table height.

Another object is to provide a compact device of this character, the parts of which are proportioned and arranged to form an ornamental symmetrical column occupying a minimum of floor space and adapted to be conveniently stored away when not in use. Other and further objects will appear from the following specification.

Referring to the drawing which forms a part of this specification:

Figure 1 is a front elevation of my improved device, and

Figure 2 is a side elevation thereof.

Figure 3 is a vertical sectional view taken on line 33 of Figure 1, and

Figure 4 is a cross sectional view taken on line 44 of Figure 1 to show the arrangement of the outlets in the head or capital of the device.

As shown in the drawing, my improved extension device forms a symmetrical column having a pedestal base ID of cast metal and a vertical shaft II. The shaft is tubular and extends upwardly to support a casing l2 at table height, the casing forming the oblong capital or head of the column and housing a plurality of convenience outlets l8--l8 etc., each adapted to receive an attachment plug of the type commonly provided on the ends of the extension cords of electrically operated appliances.

The casing comprises a cast metal frame l4 having top, bottom and side walls and an upwardly extending handle l5 integral with its top wall, whereby the device may be conveniently and safely carried. The bottom wall of the frame is provided with a central boss I2 having an 1936, Serial No. 103,580

opening therethru threaded to receive the threaded upper end of the shaft. Similar panels IS- IS form the front and back walls of the casing and are secured to the frame in removable relation by screws llll etc., each of the panels carrying an approved duplex convenience outlet l8.

Adjacent the lower end of the column just above the base, an opening I9 is formed in the shaft wall to receive an extension cord 20, the margins of the opening being covered by a circular guard or escutcheon l9 of rubber or other suitable material calculated to protect the extension cord from abrasion against sharp margins of the opening.

The extension cord is of well insulated construction and its outer end is provided with an attachment plug 2| for coupling the wires of the cord in a standard current supply outlet. The inner portion of the cord extends upwardly through the hollow shaft into the casing where it is connected to the outlets l8, substantially as indi-- cated in Figures 3 and 4.

A pair of opposed hooks 25-25 are attached to the shaft intermediate its length in spaced rela- 1.;

tion to each other and serve handily for carrying the outwardly extending portion of the cord when the device is not in use, the cord being looped about the hooks as illustrated. When the device is in use, the hooks serve to carry any portion of z.

the outwardly extending part of the cord not required to reach the source of current supply.

In use, my improved extension device is located intermediate a current supply outlet and .the apparatus it is desired to operate. The plug :1.

is then coupled in the supply outlet, a sufficient length of the cord being unwound from the hooks, and the appliances to be operated are coupled in respective outlets l8, thereby effecting a connection between the appliances and the source of current supply.

Constructed and used as above, the device will be found to have a wide field of utility in the kitchens and laundries and on the porches of iomes, in the sick room, in factories and offices, particularly the offices of dentists and physicians, and in display rooms and display windows. In fact, wherever portable electrical equipment and appliances are used the device can be employed to excellent advantage, providing a plurality of auxiliary outlets at convenient table height and affording improved extension means for operating appliances at a distance from the usual builtin supply sources.

Having thus described my invention, I claim:

1. As an article of manufacture, a portable wiring device comprising a column having a pedestal base, a vertical hollow shaft supported by the base, and a hollow head supported on the upper end of the shaft at approximate table height, a plurality of convenience outlets housed in the head, and an extension cord extending through the shaft into the head, the wires of said cord being connected to the terminals of said outlets.

2. As an article of manufacture, a portable wiring device comprising a column having a pedestal base, a vertical hollow shaft supported by the base, and a hollow head carried on the upper end of the shaft and supported by the shaft at approximate table height, a handle for the device carried by said head, a plurality of convenience outlets housed in the head, and an extension cord extending through the shaft into the head, the wires of said cord being connected to the terminals of said outlets.

3. As an article of manufacture, a portable wiring device comprising a column having a pedestal base, a tubular shaft supported by the base, and a casing carried on the upper end of said shaft and supported thereby at approximate table height, said casing forming the capital of the column, a plurality of convenience outlets housed in the casing, said shaft having an opening in the wall thereof above and adjacent the base, insulated wires connected to said outlets within the casing and extending downwardly through the shaft and outwardly through said opening, an attachment plug carried on the outer ends of said wires for coupling the device with a source of current supply, and means carried by the shaft for supporting outwardly extending portions of the Wires.

4. As an article of manufacture, a portable wiring device comprising a column having a pedestal base, a vertical hollow shaft supported by the base, and a hollow head supported on the upper end of the shaft at approximate table height, a handle for the device carried by the head, a plurality of convenience outlets housed in the head and supported by opposite walls thereof, said shaft having an opening in the wall thereof above and adjacent the base, an extension cord connected to said outlets within the casing and extending downwardly through the shaft and outwardly through said opening, an attachment plug carried on the outer end of said cord for coupling the outlets of the device with a source of current supply, and a pair of opposed hooks carried by the shaft in spaced relation to each other for supporting outwardly extending portions of the cord.
