' My ,invention relates to a means 'for operatingelectric lamp switches and it has for its object to provide a rotary lamp switch member with a 'stud mounted on .a leaf spring and movable in a slot in a casing by a cam mounted on a collarso that the switch member' may be rotated a distance by the` collar and the cam when the collar is rotated in one direction, the leaf spring permitting the stud to move inwardly out of the way when the collar is rotated in the opposite direction. When the switch member is rotated by the engagement of the stud by a cam on the collar, the cam moves the switch member a predetermined distance and with, a further rotary movement of the c ollar, the cam will push the switch into a rece its at the end of the slot which permits the fram to pass the stud. The switchmember will then be moved back to normal position by a spring provided for this purpose. The rotary switch member having the stud is connected `with an electric switch of a well ltnqwn type. l

Additional objects" ofthe invention will iin the foll` wing specification in which tlie preferred form of my invention is disclosed. li i 1n the drawings similar reference characters refer to similar parts 'in all the views in which- Figure 1 is aside elevation of a lamp provided with my i1nprovement;-Fig. Q is an enlarged sectional 'view showing miyj improved means for operatingrthe electric 6 which leads tothe lamp 7 and a second conductor with which the switch is connected. -The switch is constructed with an insulating member 8 rotatably mounted on the conductor 6, a conducting member 9 being securedto one side ofl the insulating member 8 this conducting member 9 having portio-ns bent over the periphery of the insulating member 8 at 10 and 11. It will be seeiithatthe insulating member 8 is ratchet vshaped and that it is ngagedv-gby asprin'g conducting member 12 so that with the--r0fv Y tary movement of the insulating-'member 8" the conducting member 12 may be brought into contact with the conducting member 9 at 1.0 or 11 and that with another movement of the insulating member S the conducting member 12 will be brought into contact with a surface of the insulating member 8 to open the switch. This is all of a well known construction in which the conducting member 9 is connected with the conducting member 13 to which a binding post 14 is secured.

The conducting member 9 is secured at one side of the insulating ratchet member S. At the other side ofthe insulating ratchet niem- -ber 8 there is secured a plate 15 with ratchet teeth which are engaged by theratchet plate 16 the ratchet plate 1G being held yieidingly in engagement with the ratchet plate by the spring 17, this spring 1 7 having an eX- tending terminal 18 secured to the arm 19 mounted on the plate 16. This arm 19 is provided with bifurcated ends 2O between which there is secured an end 21 of vthe leaf spring 22, a stud 23 being mounted at the outer end of the said leaf spring 22. As

will be bestiseen by referring to Fig. 3 of the drawings, this stud 23 is beveled at 24,

so that while the plate 16 may be rotated by the engagement of one ofthe cams, which will shortly be described, with one side of the stud 23, the cam'may engage the other side of the stud 23 to press the saidstud inwardly 'against the resiliency of 'the spring to permit the cam to pass the stud. The stud 23 is movably disposed in a slot 25 in the casing 5, this slot 25 having a recessI 26 4adjacent its end. 27. -It will be understood that bymoving the stud 23, theplate 1"; will inwardly against the resiliency ofthe spring name to this speciiicazion and thereby pass the stud, switch means opthe two subscribing wizneseea. erable by the first mentioned member7 and AFTHU un means for returning the rotary member and f "N 5 the stud to normal position after rotation by Witnesses:

the movement of the said cam. Geenen Kiwee@ In testimony whereof I have signed my HENRY A. Hannie.
