2 Claims. 1

The invention relates to an electric lamp, and more especially to a combination switch and light control for floor lamps.

The primary object of the invention is the provision of a control of this character, wherein it is only necessary to turn the shade of the lamp of the electric lamp for turning on or off the same, thereby eliminating the necessity of looking or feeling for the usual lamp switch, particularly when in the dark, the intensity of the light being readily controlled simultaneously when turning on the light.

Another object of the invention is the provision of a control of this character, wherein the same is unique and compact, and avoids the use of a button or snap-lever switch for service in turning on or off the light.

A further object of the invention is the provision of a control of this character, which is simple in its construction, thoroughly reliable and eflicient in operation, neat in appearance, thus will not detract from the pleasing appearance of the lamp when a part thereof strong, durable, possessing few parts, susceptible of being easily repaired should the control get out of order, and inexpensive to manufacture and install.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter described in detail, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation partly in section of an electric lamp with the control constructed in accordance with the invention applied.

Figure 2 is a top plan view thereof.

Figure 3 is a horizontal sectional view through the rheostat of the control.

Figure 4 is an enlarged vertical sectional view through the control.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail A designates generally the lamp standard of the electric floor type, and B the shade therefor.

The standard A at its upper end is formed with a cylindrical shaped hollow head In in the form of a crown and this head is fitted with bulb sockets ll, while the removable cover l2 for the said head is provided with a central opening [2 to receive the fiat insulating disc 24 which is provided with an upstanding journal stud l3 for the turning axis for a hub I 4 of a lamp shade frame l5 of the shade B, the hub I 4 being fixed to the arms l6 of the said frame 15. The hub I4 is retained on the stud l3 by a screw l1 and washer l8, respectively.

Stationarily mounted within the head I0 is an insulating base IQ for the resistance coil 20 with which contact is made by a flat rotatable contact 2| engaged on a pivot 22 centrally fitted at 23 to the base IS, the pivot 22 being threadedly received in the sleeve or hub 24' of the disc 24 in the cover l2, the disc 24 being of a smaller diameter than the central opening 12' forms an annular space 25 for accommodating the insulated L-shaped member 26 attached to contact 2|. The member 26 travels in the annular space 25 and its forked upper end saddles an arm l6 of the frame [5 of the shade B, so that when the latter is turned clockwise or counter clockwise the contact 2l which has one end thereof engaging the resistance coil 20 will be similarly moved.

The coil 20 and the contact 2| are terminally connected electrically in a current supply circuit 21 of a house wiring line (not shown) which delivers current to the bulb sockets l I for illumination of the lamp bulbs 28 as usual, the coil and contact, 20 and 2| intercept the circuit to the sockets II, for the turning on and off of the bulbs 28. The base I9 is provided with

stops

29 and 30, respectively, and when the contact 2! engages the stop 29 the circuit 21 is open, yet when the said contact 2! engages the stop 30 the circuit remains closed, the latter being constantly closed while the contact 2| traverses the coil 20, and according to the position of such contact 2| thereon the intensity of the light is increased or decreased. When the contact 2| is moved counter clockwise the same engages the stop 29 and on moving the contact 2| clockwise the stop 30 is engaged thereby.

The shade B completes the movement of the contact 2! and it should be obvious from the foregoing taken in connection with the drawing that the bulbs 28 are lighted and extinguished by turning the said shade B, and also the intensity of the light is regulated thereby.

What is claimed is:

1. In an electric lamp including a pedestal, an enlarged upper end on said pedestal, a lamp shade having a rotating frame on said pedestal, a resistance coil mounted on a circular insulating base secured to occupy a stationary position in the enlarged upper end of the pedestal of the lamp, a contact rotatably mounted in the upper 3 end of the pedestal contacting said resistance and adapted for operation through the medium of the frame of the lamp shade, a source of current connected to said resistance, a lamp bulb connected to said contact, and an L-shaped insulated member secured to said contact having the upper end thereof forked to provide an operboth directions.
