Application July 17, 1958, serial No. 149,182

1 claim. (ci. 24o-12s) This invention relates toa lamp, and more particularly to a lamp which includes a novel means for turning the l light bulb on or of. l

d The object of the invention is to provide a lamp which includes a movable stem, whereby when a person desires {to actuate the light bulb or turn the light bulb on or off, it is only necessary to manually grip a portion` of the stem and move the stem downwardly so as to cause a switch to be engaged or actuated.

A still further object of the invention is to provide a lamp which is constructed so that a light bulb may be turned on or oii without the necessity of manually pulling a chain, or turning a switch, wherein the present invention facilitates the actuation of a lamp as for example when the lamp is located in a darkroom or other locality, since the present invention permits the lamp to be more readily actuated.

A further object of the invention is to provide a lamp which is extremelysimple and inexpensive to manufacture.

Other objects and advantages will be apparent vin the course of the following description.

In the accompanying drawing, forming a part of this application, and in which like numerals are used to indicate like parts throughout the same:

Figure 1 is an elevational view illustrating the lamp of the present invention.

Figure 2 is an enlarged sectional view taken on line 2-2 of Figure l.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Referring in detail to the drawing, the numeral indicates the lamp of the present invention, and the lamp 10 includes a base which is indicated generally by the numeral 11. The base 11 is provided with an outer section 12 so that the base 11 has a suitable formation. The base 11 is provided with a recess 13 in its lower portion, and the basell is also provided with a vertically disposed bore 14 which communicates with the recess 13. The numeral 1S indicates a horizontally disposed plate which is 'positioned inthe recess 13, and the plate 15 may be secured in place by means of suitable securing elements 1 6. The numeral 17 indicates wires which extend through a central aperture 18 in the plate 15.

The numeral 19 indicates a switch which is connected to the plate 15, and the switch 19 is provided with a push button 20 for a purpose to be later described. v

There is further provided a vertically disposed sleeve or guide 21 which is seated in the bore 14, and the sleeve 21 is provided with a cutout 22, in the lower portion thereof,

and this cutout 22 denes a stop shoulder 230 in the lower portion of the sleeve 21. The numeral 24 indicates a` lamp shade which is connected to the stem 23 in any suitable manner.

The stem 23 is provided with a longitudinally extending passageway 25 which includes an upper section 26 of a reduced diameter, and a lower section 27 of increased diameter. The numeral 28 indicates a cutoff spring which has its upper portion fitted inthe section 27, and the lower will not become disconnected from the sleeve 21, as forlee ,bracket 33 further includes a horizontally disposed lower iinger32 which is movably mounted in the cutoli 22. The finger 32 is mounted to move into and-out of engagement with the push button 20, and the finger 32 is also mounted to, move into and out of engagement with the stop shoulder 230 of the sleeve 21.

From the foregoing, it is apparent that there has been provided a lamp that includes a manual means for actuat- Aing the light bulb of the lamp. According to the present invention, with the parts arranged as shown in the drawing, it will be seen that by gripping the stem 23 and moving the stem 23 downwardly, the bracket 33 will be moved downwardly and the bracket 33 is connected to the stem 32 as at 31. As the bracket 33 moves downwardly, the linger 32 will move down into engagement with the push button 20 so as to actuate the switch 19. Since the switch 19 is connected to the light bulbthrough the wires 17, it will be seen that the light bulb can be turned on or oli by the downward movement of the stem 23; When pressure is released on the stem 23 the, cutoff spring 28 will return the stem Z3 to a raised position. Then, when the user desires to again actuate the light bulb or turn the light bulb on or oli, it is only necessary to repeat the cycle and again move the stem 23 downwardly. It is to be noted that when pressure is released on the stem 23, upward travel of the stem 23 will be limited by the finger 32 which moves in the cutoii 22, since the finger 32 will engage the shoulder 230 on the lower portion of the sleeve 21, and this inter-engagement between the linger 32 and the shoulder 230 provides a stop means for limiting upward travel of the stem 23.

While the present invention has been described in connection with the turning on or off of a light, it is to be understood that the switch 19 may be of a type which selectively controls actuation of one or more filaments or bulbs so that such lights can be turned on or oli otherwise actuated by the downward movement of the stem 23.

The parts can be made of anysuitable material and in .different shapes and sizes.

The sleeve 21 is secured to the base in any'suitable manner, as for example by means of securing elements, or by means of an adhesive or the like. The lamp of the present invention consists of a minimum number of parts and is simple and inexpensive to make whereby the lamp can be produced and sold at a very minimum cost. Also, the construction of the lamp permits the lamp to be readily and conveniently assembled or disassembled.

The lamp is constructed so that a light can be turned on or oii by the manual downward pressure on .the stem 23. Furthermore, this mechanism can be used for changing from one bulb being on or oil to two or more bulbs being on or oli.

The brackets 33 also serves to insure that the stem 23 stem 23 and this is due to the fact that the nger 32 will engage the stop shoulder 230.

,l It is to be noted that the lamp of the present invention is constructed so that a person does not have to hunt for a button to push or a knob to turnror a chain to pull and to actuate the lamp it is only necessary to push down on the stem and any portion of the stem may be gripped to push down.' Similarly when a person wishes to put out the light the same downward pressure will turn oi the light orchange from one bulb being on to others being on by the proper wiring applied thereto. All of the working parts are strong and are safely enclosed as shown Vinv the drawing. Y y

The base can have any suitable or desired formation since it may be square or of any other design or shape.

The above description of the invention is for illustrative purposes only and it is understood that modifications may be made in the construction Within the scope and spirit of Vthe following claim.

I claim: A lamp of the class described, having a base, a recess in the lower portion of said base, said base having in itsr l said plate, wires extended through said aperture and connected to said switch, a sleeve seated in said bore and having a lower end abutting said plate, there being a cutout in the lower portion of said sleeve providing a stop shoulder, a movable stem seated in said sleeve, there being a longitudinally extended passageway in said stem for the passage therethrough of said wires, said passageway including an upper section of reduced diameter and a lower section of increased diameter, and a coil spring having its upper end projecting into the lower section of the passageway, said coil spring having the lower end abutting said plate, a bracket including a vertically disposed leg positioned in said cutaway portion and secured to said stem, said bracket further including a horizontally disposed ingery which is provided to` move into and out of engagement with said switch, said nger being mounted to move in said cutout and being mounted to move into and out of engagement with said shoulder.
