- Application August 4, 1950;. Serial No. l'7-7','630- 2 Claims.
My invention relates. toa new and useful improvement in a lamp switch adapted for use. on lamps of various types such. as. floor lamps, table lamps, etc. From the: description. it will also appear that. the. switch is: adapted for other purposes. although it. is; intended. primarily for use on lamps.
An. object. of the invention. is the provision of a lamp switch which. will. be economical of structune... durable, compact and highly" efficient in use.
Another object of the invention is the; provision a-"lamp switchof a. longitudinally movable plunger adapted for actuating theswitchtoclosing; position on one movement and. on the next movement actuating theswitch' to open position.
Another. object of the invention,v is. the provision. of; a lamp; switch of. this class which may be mounted. in. lamp; socket;
Other. objects will: appear hereinafter.
It. is recognized that various modifications and changes may bev made;- in. the detail of structure illustrated and itis. intended that the present disclosure shall. be considered but the preferred embodiment. v V
Forming: apart. of this application. are drawings. in; which, I

Fig. '7 is. a sectional view taken. on line 1-1 of Fig. 6.. v
Fig; 8. i'sQa diagrammatic. view illustrating the use of the invention as a wall switch.
In the drawings I haveillustrated. the inventionused by the lamp haying 1a supporting: pedestall l5; extending upwardlyfrom which is; apipe l6 connected to and projecting outwardly from which are the tubes H and I8 through which the wires l9 and 20 are led. Tubes IT and I8 are rigidly connected to a housing 2| on which is mounted a cap 22 having a neck 23. A shade 6| is supported by a frame 62 extending outwardly from a hub 63 which rests upon the neck 23.
As shown in Fig. 2 there is threaded into the neck 23, a tubular fitting 24, to which is attached the bracket arm 25 having the downwardly projecting plate 26 which serves as a support for 2. the block: 21: of insulating material on whiclr'a switch is mounted.
Mounted on. the: block 21. is a metallic. bar 28 having the angularly turned portion 3|]? whichis connected in. contact. with the threaded. metallic shell. 3|: intov which the threaded: portion. 32 of alight bulb 33 is threaded. This bar 28 is connected on the block 2.1 by means. of a. bolt 29 which serves as aterminalv and. to which the wire. 20 is. attached so that the shell 3| is thus electrically connected to the wire 20. The. light bulb is also connected to this. wire. through the connections already described, the: threaded terminal portions 3| being metallic. constituting one of the. terminals of the lightbulb. The other terminal. 34 of; the light bulb is in contact with the metallic. plate 35 which is' mounted on the block 21 by means of thBrbOlt 35a, which also connects 35. tothe metallic. plate 3 which. constitutes one of the. terminals of. the; switch.
Mounted. on the block 21 projecting outwardly therefrom is a. shaft 38,. carrying; at its outer end ahead 39 towhich is attached one end of a spring 40 which. embraces the shaft 38. Rotatively mounted. on this shaft 3811s a disk 4| to which. the other end 42. of. the shaft, havingfa tongue. 42. projecting; outwardly therefrom and through which is attached the other end 43-of the spring 40. Formed in this disk 4i is a plurality of spaced. apart openings 44.
Rotatably mounted on the. shaft38 is a metallic disk 45, disk 4| beingformed from suitable insulating material. This metallic disk. 45 is provided, at diametrically opposite points, with a leg 46. These legs 46 extend. outwardly from the disk. 43 and. are inclined downwardly for engaging the upwardly extending tongues 41 and 48 on the. plates 31; and 49.. This. plate. 49 being a metallic plate. secured. to the block 2"! by the screw 50...
The rod' 5| is connected to the tongue 42 and also the plunger 52 which slidably projects through the fitting 2.4. and which is provided at its. outer end. withv the. knob 5.3.v Projecting outwardly from the. base. of. the metallic. disk 45 are the tongues 54 which are. inclined-towards their free end. to extend outwardly from the. face of the disk, 45'. Construction. is such. that upon pressingjthe plunger 52 downwardly the. disk 4| of insulating material will. be. rocked downwardly against the. tension of the spring 40. 'Asthe rocking movement continues downwardly the tongues 54 will engage in the opening 44 formed in the disk 4| and thus the disk 45 will be rotated. Upon pressing the plunger downwardly this disk 45 will be rotated to a position where the members 46 engage the inclined portion 41 and 48 and thus connect the wire l9 electrically to the terminal 34 of the lamp bulb so as to close the circuit to the light bulb.
OFFICE 1 As the legs 46 ride upwardly on the inclined tongues 41 and 48 disk 45 will move outwardly that is to the left of Fig. 3 against the compression of the spring 40. This spring 40 will serve to restore the plunger to its normal position upon release of pressure on the plunger and in moving to its normal position the disk 4| will rotate and the inclined members 54 are disengaged from the opening 44 and in this movement the disk will move to the left of Fig. 3 against the compression of the spring 40. When the disk 4| returns to its former position, the openings 44 will again be in registration with the tongues 54 and these tongues 54 will engage in the openings 44 so that upon the next downward movement of the plunger 52 the metallic disk 44 will again be moved to move the members 46 out of engagement with the members Al and 48, thus opening the switch.
In this way when the lamp is constructedin this manner and provided with a switch of this type, it is obvious that a downward pressing on the knob 53 will effect a closing of the switch and a lighting of the lamp and a spaced second downward pressure of the member 53 will open the switch.
The structure is one which lends itself admirably for installation in a lamp whether it be a table lamp orfioor lamp and is one which is compact and can be easily operated while at the same time it ispossessed of a minimum number of parts thus avoiding the likelihood of disarrangement of various parts.
In Fig. 18 I have shown a diagrammatic view in which the switch is used as a wall switch and I have illustrated a switch housing 56 mounted in the wall 55. A red 53 is actuated by the plunger 57 and rod 58 corresponding to the rod of Fig; 2 serves to actuate a disk lia. which corresponds to the disk 4|, the remaining parts being the same. Leading into the switch housing are the conduits 59 and 60 through which the electric wires are led.
What I claim is 1. In combination, a switch housing; an in sulating supporting block on said housing; a pair of spaced apart terminals mounted on said block; a shaft extending outwardly from said block; a rotatable metallic contact member rotatably mounted on said shaft; legs projecting outwardly from said contact member adapted upon rotation of said contact member for moving into and out of engagement with said terminals for making and breaking a circuit therethrough; a rotatable actuating disk, rockably mounted on said shaft; a pluralityv of spaced apart openings formed in said actuating disk; a pair vof spaced apart lugs extending outwardly from one face of said metallic member andengageable in said openings; a spring on said shaft normally urging said actuating disk into position for receiving said lugs in said openings, said actuating disk, upon rocking inj'one direction, effecting a rotating of said metallic disk a predetermined distance and 'upon rocking in the opposite direction for riding over said lugs against the compression of said 4 spring; a tongue projecting outwardly from said actuating disk; a plunger extending outwardly from said housing; a rod connecting said tongue with said plunger and adapted upon inward movement of said plunger for rocking said actuating disk in a direction to move said metallic disk, one end of said spring being connected to said tongue and normally maintaining said actuated disk rocked to a position for retaining said plunger in outwardly moved position, said rod fbein'g inclined to the axis of said plunger.
2. In combination, a switch housing; an insulating supporting block mounted in said housing; a pair of spaced apart terminals mounted on said block; a shaft extending outwardly from said block; a rotatable metallic contact member rotatably mounted on said shaft; legs projecting outwardly from said contact member adapted upon rotation of said contact member for movement into and out of engagement with said terminals for making and breaking a circuit therethrough; a rotatable actuating disk, rockably mounted on said shaft; a plurality of spaced apart openings formed in said actuating disk; a pair of spaced apart lugs extending outwardly from one face of said metallic member and engageable in said openings a pring on said shaft normally urging said actuating disk into position for receiving said lugs in said openings, said actuating disk, upon rocking in one direction, effecting a rotation of said metallic disk a predetermined distance and upon rocking in the opposite direction for riding over said lugs against the compression' of said spring; a tongue projecting outwardly from said actuating disk; a tubular fitting mounted on one end of said housing and projecting inwardly and outwardly thereof and having a recess in its inner end; a plunger slidably projecting through said fitting; a head on the inner end of said plunger engageable in said recess; a rod pivotally connected atone end to the head bearing end of said plunger and pivotally connected at its opposite end to said tongue for, upon inward movement of said plunger, rocking said actuating disk in a direction to move said metallic disk, said rod being inclined to the axis of said plunger.
