Chile Application September 29, 1947, Serial No.'776,845

An object of the invention is to provide an electric lamp of simple construction in which a switch is incorporated in the lamp structure for turning the power off and on, and which switch is operated by movement of the body portion of the lamp itself. 7

Another object of the invention'is to provide a lamp construction which eliminates localizing at a given point the operating switch to be separately operated and thus makes it possible for the body itself or a part of the body when being moved to operate the switch.

Other and further features and objects will be apparent from the following description of a preferred embodiment of the invention with reference to the accompanying drawings in which:

Fig. 1 is a side elevational view of a lamp, parts thereof being broken away for clarity;

Fig. 2 is a cross sectional view taken on the line 2-2 of Fig. 1 looking in the direction of the arrows, and

Fig. 3 is an enlarged fragmentary view of the switch actuating mea is.

The lamp structure, as shown in the drawings, comprises two main body portions I and 3. The portion I has an electric lamp socket of a usual type construction therein for holding an incandescent bulb 2. The socket is shown in dotted lines in Fig. 1. The body portion 3 is a wall bracket type of fixture and is shown as being mounted on a wall. It is to be understood that the drawing is only one preferred embodiment and that the principle of this invention may be applied to table lamps, floor lamps, ceiling lamps, etc.

The body portion 3 is secured to the wall and supports the body portion I by means of the arms 4 and 4 which are pivoted on members 5 and 5'. The arms 4 and 4' enter the body portion 3 through small openings 9 which permit a small horizontal rotation of the body I in relation to the body 3 around the pivots 5 and 5'.

The arm 5' is extended and has secured to the end 6 thereof a toothed sector 6. This toothed sector 6' swings about the pivot 5' upon a movement of the body portion I. The toothed sector 6 engages a toothed pinion I and causes the pinion to rotate. The pinion 'I has a triangular projection IE] on the underneath surface for engaging with a notch I I in the operating member 5 Claims. (Cl. 240-43) 2 of the switch 8 secured in the body 3. By means of the projection Ill and the notch II,'the switch canonly operate in one direction upon movement of the body portion I. Upon a return movement of body portion I the pinion I will not engage the switch operating member but will freely rotate. A spring I3 for urging the projection I0 into engagement with the notch I I is provided which will also allow the pinion I to rise when the" direction of movement of the body portion I is reversed. A spring I2 is secured to the body portion 3 and to the toothed sector 6' to return the body p ortion I to a center posi-v tion after the lamp has been lighted.

If desiredthe switch can be so arranged that the light will operate when the body portion I is moved to either right or left of center. Also if desired the switch can be arranged to operate only in a central position of the body portion I and have off positions to the right or left.

To operate the lamp any portion of body I is pressed so as to turn the body I around pivots 5 and 5' from position m to position n. The arm 6 and the sector 6' will thus be moved in a counter-clockwise direction and the pinion 'I rotated in a clockwise direction thereby actuating the switch 8 and turning on the bulb 2. The spring I2 will then operate to return the body portion I to the central position m. In order to turn the light off the identical procedure is followed and the light is thus always ready for action at a slight pressure against the body portion I.

Various changes may be made in the present device in order to adapt the invention for different circumstances without departing from the scope thereof.

I claim:

1. An electric lighting device comprising a stationary part, an electric switch in said stationary .part, a movable part horizontally removed from said stationary part, an electric lamp socket in said movable part, upper and lower vertically spaced pivoting means in said stationary part, horizontally extending arm members secured to said movable part and rotatably supported by said pivot means to pivotally connect said movable part to said stationary part, a toothed pinion operatively connected to said switch, a toothed sector on one said arm member forming an extension thereof in contact with said toothed pinion on said switch for actuating said switch when said movable part is moved in a horizontal direction.

2. In an electric lighting device as claimed in claim 1, said switch being a rotary switch, an

Operating member in said switch, a triangular notch in the upper surface of said operating memfber, a triangular projection on the underside of said toothed pinion, a spring normally maintaining engagement between said pinion and said operating member through said projection and said notch whereby upon movement in one direction of said movable member said notch and projection will engage and operate said switch and whereas when moved in an opposite direction said toothed pinion will rise aginst the action of said spring and cause disengagement of said projection and said notch.

3. In an electric lighting device as claimed in claim 1, a spring secured to said stationary part at one end thereof, the other end of said spring being attached to said toothed sector on said arm for returning said movable part to a central position after movement thereof to actuate said switch.

4. An electric lighting device comprising a hollow stationary part, upper and lower pivoting means secured to said stationary part, a, rotary switch in said stationary part, horizontally extending arms pivotally mounted on said pivoting means, a hollow movable body secured to said arms and horizontally displaced from said stationary body, an electric lamp socket in said movable body, an operating member on said switch, a, toothed pinion superimposed on said operating member, a spring normally urging engagement between said operating member and said pinion, an extension on one said arm, a

toothed sector on the free end of said extension in contact with said pinion, and engagement means between said operating member and said pinion operable in only one direction of movement by said pinion upon horizontal movement of said movable body.

5. In an electric lighting device as claimed in claim 4, said operating member having a right angle shaped notch in the upper surface thereof, said pinion having a right .angle shaped projection on the lower surface thereof, said spring normally urging said projection into said notch on rotation of said pinion in one direction and allow disengagement thereof upon rotation in an opposite direction, said notch and said projection comprising said engagement means.
