J. Application May 4, 1944, Serial No. 534,138 2 Claims. 1 (Cl. 240-123) 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 look ing or feeling for the usual lamp switch, particu larly when in the dark, the intensity of the light 10 being readily controlled simultaneously when turning on the light. Another object of the invention is the pro vision 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 pro vision of a control of this character, which is frame l5 of the shade B, the hub I 4 being ?xed 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 ?tted at 23 to the base IS, the pivot 22 being threadedly re ceived in the sleeve or hub 24' of the disc 24 in the cover l2, the disc 24 being of a smaller di ameter than the central opening 12' forms an annular space 25 for accommodating the in sulated L-shaped member 26 attached to con tact 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 clock wise the contact 2l which has one end thereof simple in its construction, thoroughly reliable and 20 engaging the resistance coil 20 will be similarly e?icient in operation, neat in appearance, thus moved. will not detract from the pleasing appearance of The coil 20‘ and the contact 2| are terminally the lamp when a part thereof strong, durable, possessing few parts, susceptible of being easily connected electrically in a current supply circuit 21 of a house wiring line (not shown) which repaired should the control get out of order, and 25 delivers current to the bulb sockets l I for illumi inexpensive to manufacture and install. nation of the lamp bulbs 28 as usual, the coil With these and other objects in view the in and contact, 20 and 2| intercept the circuit to vention consists in the features of construction, the sockets II, for the turning on and off of the combination and arrangement of parts as will bulbs 28. The base I9 is provided with stops 29 be hereinafter described in detail, illustrated in the accompanying drawing, and pointed out in 30 and 30, respectively, and when the contact 2! engages the stop 29 the circuit 21 is open, yet the claims hereunto appended. when the said contact 2‘! engages the stop 30 the In the accompanying drawing: Figure 1 is an elevation partly in section of an . circuit remains closed, the latter being constantly closed while the contact 2| traverses the coil 20, electric lamp with the control constructed in 35 and according to the position of such contact 2| accordance with the invention applied. thereon the intensity of the light is increased or Figure 2 is a top plan view thereof. decreased. When the contact 2| is moved coun Figure 3 is a horizontal sectional view through the rheostat of the control. ter clockwise the same engages the stop 29 and Figure 4 is an enlarged vertical sectional view on moving the contact 2| clockwise the stop 30 is 40 engaged thereby. through the control. Similar reference characters indicate corre The shade B completes the movement of the sponding parts throughout the several views in contact 2! and it should be obvious from the the drawing. foregoing taken in connection with the drawing Referring to the drawing in detail A designates that the bulbs 28 are lighted and extinguished generally the lamp standard of the electric ?oor 45 by turning the said shade B, and also the in type, and B the shade therefor. tensity of the light is regulated thereby. The standard A at its upper end is formed with a cylindrical shaped hollow head In in the What is claimed is: 1. In an electric lamp including a pedestal, an form of a crown and this head is ?tted with bulb 60 enlarged upper end on said pedestal, a lamp shade sockets ll, while the removable cover l2 for the having a rotating frame on said pedestal, a re said head is provided with a central opening [2’ sistance coil mounted on a circular insulating to receive the ?at insulating disc 24 which is pro base secured to occupy a stationary position vided with an upstanding journal stud l3 for in the enlarged upper end of the pedestal of the the turning axis for a hub I 4 of a lamp shade lamp, a contact rotatably mounted in the upper 2,408,669 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 cur rent connected to said resistance, a lamp bulb connected to said contact, and an L-shaped in sulated member secured to said contact having the upper end thereof forked to provide an oper ative connection between said contact and the frame of said shade. 2. The invention as described in claim 1 where~ in stops are provided at one end of the resistance coil for limiting the movement of the contact in _ both directions. LESLIE N. MATTSON.
