PORTABLE ELECTRICAL DEVICE.

2 all where it may concern:

-Be it known that we, ELBERT R. WINS- LOW and flame A. Jonns, citizens of the United States, residing at Kearney, in the county of Buffalo and State of Nebraska, have invented certain. new and useful Improvements in Portable Electrical Devices, of which the following is a specification.

This lnvention relates to new and useful improvements in a ortable electrical device for use in offices, omes and by travelers and comprises an electrical fan and an electric incandescent light mounted on the same frame and provided with a socket'by which' the device may be attached to a bracket, electrolier, drop cord or wherever an incandescent light bulb can be made to glow.

The primary object of the invention is to combine in a single article which is both small and light and may be transported readily in an ordinary 'valise, an electric motor driven fan and an electric light, each included in an independent circuit connected to contacts in thesocket, and a key adapted to operate a movable member in connection with. or adapted to be connected to lead wires carrying current, said member when moved by the ke in different directionsand at difierent distances cutting in either the fan motor alone, the light alone, or both simultaneously. Both may also be cut out of circuit when desired.

' Another object resides in the'provision of a unitary device embodyin an electrically driven fan which is inclose within a frame and on which frame an-electric lighting device is supported.

Other objects of the inventi'onwill be set forth in the following description and pointed out in. the appendedclaims, reference being had to the accompanying drawings in which: 7

ing the switch in osition to render both the electric lighting evice and the fan active.

Referring to the drawings in which similar reference characters denote like parts throughout the several views, 10 designates an electric motor of any improved type on the shaft 11 of which is mounted a fan 12 adapted to rotate with the motor. Inclosing the motor 10 is a casing 13 of any suitable .form, but as shown formed in two parts 14 and 15, the upper part 15 having a flange 16 on its lower end to fit over the part 14, a set screw 17 securing the two parts together.

At the bottom of the casing 13 on opposite sides thereof are outwardly 'pro1ecting' bosses 18 in which are fastened the ends of two tubes 19, said tubes extending horizontally from the casing a shortdistance beyond the wings of the fan 12, then turning downwardly as at 20 to a point below the :fan, turning inwardly once more as at 21 to a point near the axis of the motor where they are attached to a lamp socket 22.-

Con ducting wires

23 and 24 lead froma lamp 25 mounted in said socket through the

bent tubes

19, 20, 21 into the motor casing 13, to I a socket 26 on the top ofthe casing 13.

Projecting from the motor casing at the center thereof is a threaded hollow neck 27 upon which the enlarged lower end 28 of the socket 26 is screwed.

The socket 26, as shown is made of some insulating material such as porcelain, on

the upper end of which is fastened a sleeve 29 made of metal. A metal stud 30 is fas tened to the socket at the center thereof and these two metal parts serve to make and 37 are formed in the plate 33. The. I

upper ends of the

plates

32 and 33 are connected by suitable wires with the

contacts

29 and 30 on the outside of the socket. A

block 38 made of insulating material conextends transversely through the socket and through a horizontal slot 40 in the block, I

said key having a bit 41 in the form of a crank bend lying within the slot in such position that when the key is turned by the thumb piece 42 the

plates

32 and 33 may be raised or lowered. It is to be understood that the

plates

32 and 33 will be provided with suitable guides to direct them in their upward and downward movement. Such guides have been omitted in the drawings for the sake of clearness.

Within the cavity 31 of the socket 26 are above the former contacts, their free ends projecting into the offsets 34, 36 of the sliding plates in position to make contact therewith when said plates are moved upwardly. These upper contaot plates form theterm1-

nal oit wires

47, 43 that connect with the commutator oi themotor 10.

The device as, shown and. described is simple, compact and convenient, readily transportable and may be connected for use to any socket capable of holding an incandescent light. When in position with the key 40, placed as in Fig. 3, the current w ll be cut out from both the fan and theelectrm light. lit it be desired to set the fan in motion, the key is turned sufiiciently far to move the

sliding plates

32, 33 upward untll the offsets 34 vand 36 in said plates come in contact with the terminals 45, 46, as shown in l ig. 4. To cut out the fan and cut in the light the key is turned in an opposite direction to lower the sliding plate, see Fig. 5, thereby breaking contact with the terminals and 46 and connecting them with the

terminals

43 and 44, the current;

passing thence by way of Wires-23, 24 to the electric light 25. W hen it is desired to use the light and tan simultaneously, an extreme movement of the key in either direction will. move the odsets 34 to 37 on thetwo sliding plates in contact with both sets ,of terminals 43, 46, thus switching both light and fan in circuit.

A simple portable device such as ole-- scribed is easily carried about and applied to a socket over or one side of a desk or table and either lit "l ian or both usedas desired.

h n 9 t When traveling the fan may be packed in a valise and used wherever the traveler stops it the place be wired for electric lighting.

The tubular frame incloses the tan, supports the electric lighting device and receives and conceals the circuit from the lighting device to themotor casing. A frame member 50 connects the portions 20 of tubes 19 of the tubular frame.
