MEANS FOR ACTUATING ELECTRICAL SWITCHES Filed April 14, 1948 Patented Jan. 25, 1949 UNITED STATES PATENT OFFICE/V,

MEANS FOR ACTUATING ELECTRICAL SWITCHES 1 Claims. I

This invention relates to means for actuating electrical switches and has particular application to fioor lamps, table lamps, electric fans and other electrical operating devices supported on standards and the like.

One of the objects of this invention is to provide an improved means for manually operating an electric switch by remote control.

While this invention has application to any number of electrically operated devices, one of its specific applications is in its use with electrical floor lamps, as shown in the appended drawings. The disadvantages inherent in operating the switches on standard lamps are readily apparent. The switch is either located at the top or bottom of. the lamp and the switch button or chain must be engaged directly by the fingers or hands in turning it on and off. This necessitates the fumbling around and searching for the switch button or chain if the room is dark and also the getting up or elevating the hand above the person's head in turning on the switch if seated, all of which is an inconvenience to the person. With my invention this is eliminated as the switch may be remotely operated by a slight manipulation of the lamp standard, thus providing a large surface area which can be grasped by the hand and in any position.

The construction of my invention is simple, has few parts, is inexpensive and economical to construct, and is sturdy in construction. Other objects will become apparent as this description progresses.

In the drawings the invention is shown specifically applied to an electric floor lamp, although it will be understood that it may be similarly used in table lamps, electric fans and other devices wherein a switch is actuated.

In the drawings:

Fig. 1 is a cross sectional view showing the lamp standard and base with my invention;

Fig. 2 is a cross sectional view taken on line 2-2 of Fig. 1;

Fig. 3 is a cross sectional view taken on line 3-3 of Fig. 1;

Fig. 4 is a side elevational view of the lamp with my invention, and

Fig. 5 is a cross sectional view of a modified form of accessory construction of my invention.

The lamp comprises a, hollow base l0 into which is threaded as at l2 a pipe l4 which forms the support for the lamp standard, generally desig- The column It has an integrally formed collar 24 extending upwardly of. the column and which 'forms a well or sleeve space 26.

Secured in the base adjacent the pipe is an open bottom shell or cap 28 internally threaded as at 30 to receive the threaded neck 32 of the conventional push button switch 34 and to secure the switch in position. The depressible switch button 35 extends upwardly of the neck and is adapted to be engaged by a plunger 38, the lower end of which is supported in the reduced neck of the shell. The upper portion of the plunger extends through an opening 42 in the top of the column and is secured by means of a disc 43 to a. slidable sleeve 44; presently to be described.

The plunger 38 has a transverse pin 45 and a coil spring 43 surrounds the plunger and is interposed between the top of the shell and the pin to normally urge and maintain the plunger and sleeve upwardly in its elevated position, as shown in Fig. 1.

Snugly surrounding the major length of the pipe [4 is a supporting column or spacing tube 50, the lower end of which rests inside the well 26 and on top of the column Ill.

The upper ornamental column 52 is positioned on the pipe and engages the top of the spacing tube 50. The column has fixed thereto an internally threaded washer 54 which engages the threaded end 15 of the pipe i4. The column 52 has an integrally formed collar 53 which defines a sleeve space 55 within which is contained the upper end of the spacing tube 50, as well as the slidable sleeve 44. Rotating of the column 52 will take up any slack or looseness between the tube [4, spacing tube and the upper and lower columns 52 and [8 respectively as is well understood, but will not effect the movement of the slidable sleeve 44.

Surrounding the major length of the pipe l4 and spacing tube 50 is the slidable sleeve 44, previously referred to, which is spaced from the tube 50 and vertically movable with respect thereto. The sliding sleeve 44 is slightly shorter than the length of the spacing tube 50 to permit for a slight vertical movement within the sleeve spaces.

threaded end I5 of the pipe i 4 as is Well understood in the art.

The push button switch 34' is of conventional construction and the push button 36 alternately opens and closes the circuit when successively 3 depressed. The conducting wires 33 from the switch are connected to wires 31 leading to the electrical outlet, as well as to wires 39 passing up through the inside of the pipe I4 and connected to the conventional sockets in the upper part of the lamp, as is well understood.

When it is desired to operate-the switch, the sliding sleeve ll may be grasped anywhere along its length and pushed down slightly to that shown in dotted lines in Fig. 1. The plunger 38 will be simultaneously depressed against the tension of the spring 48 to depress the push button 36 of the switch. When the push button is depressed the circuit will be closed and the lights illuminated. The spring 48 will urge the sleeve 44 back to its raised position, as shown in full lines in Fig. 1, when the hand is removed from the sleeve. When the sleeve is next manually slid downwardly, the

' push button will operate to open the circuit in the lamp, and so on.

In Fig. 5 is shown a modified form of construction permitting attachment as an accessory to lamps already assembled. Thepipe Ila (corresponding to pipe It in Fig. 1) has a threaded end llb extending below the top of the hollow base It. Threadedly secured to the threaded end b is a bracket 56 which supports the push button switch 34a, The threaded neck 32a of the switch is screwed into the bracket and supported thereby. A shell or cap 58 is secured to the neck of the switch and the shell has an opening 59 through which the plunger 38a extends to engage the depressible button 36a of the switch. The plunger is operated precisely as that described in connection with the construction of Fig. 1.

The lamp as constructed with my invention is firmly secured and held together as efiectively as the best lamps now constructed in the art, and the introduction of my invention to such lamps does not weaken or in any way impair the sturdiness of the lamp.

It will be understood that various changes and modifications can be made with respect to the above without departing from the spirit and scope of my invention.

What I desire to secure by Letters Patent is:

1. In a lamp including a base and a stationary vertical support secured thereto, a switch secured to said lamp exteriorly of said vertical support, collars secured at the upper and lower portions of said support, a vertically slidable sleeve surrounding said support and vertically movable with respect to and independently of said base with the opposite ends of the sleeve slidably confined within said collars, and so constructed and arranged that when moved vertically it will operate said switch.
