CEILING-FAN.

Specification of Letters Patent. Patented Nov. 24, 1908.

Application filed November 20, 1907. Serial No. $03,025.

Fans; and I do hereby declare the following 7 to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

V The object of this invention is to so locate the switch of an electrically-operated overhead or ceiling fanas to make it impossible or extremely difficult to effect the unauthorized closing of thecircuit and actuation of the fan. i

Another object is to avoid having the switch appear as a separate element from the fan and its motor.

The invention will be hereinafter fully set forth and particularly pointed out in the -Cl&l111.

In the accompanying drawings, Figure 1 is avertical longitudinal sectionalview of a ceiling fan equipped with my improvements, parts being shown inside elevation and other parts broken away. Fig. 2 is a sectional view of the key-end of the switch rod. Fig. 3 shows such end in perspective with the key or handle detached.

Referring to the drawings, 1. designates the motor in its entirety, all the parts of which may be of any suitableor preferred form of construction except as modified to carry out the purposes of my invention.

The armature shaft 2 is made hollow, and

to its lower end is secured the hub 3 of. the fan blades 4. Within this armatureshaft is located a tube 5 which extends beyond the fan hub 3 and supports at its lower end the tubular casing 6 carrying the ordinary electric light sockets.

7 designates the switch which is located within a globular casing 8 secured to the lower end of a supporting tube 9, while to its lower end is secured the upper hood 10 of the motor casing. The switch, as usual, comprises two laterally extended arms which are designed to have make and-break contact with terminal posts 12 to which the service wires 13 are connected, such posts being mounted in an ordinary porcelain base.

made apparent.

'd'ifiicult, if not impossible.

The switch arms are mounted on the upper end of a rod 14 depending from the switch base and extended Eongitudinally through the armature shaft a 1d inclosed supporting tube 5. This rod projects through and beyond the bottom casing 6, and at its lower material, held thereonby a pin 16. This sleeve 15 is desi ed to receive the reduced end of a handle 17, which is secured bya pin 18 or other suitable means. When this key is attached to the switchrod the latter may be readily turned axially to' open or closethe switch, but by removing the key,

as .by withdrawing the retaining pin 18, it

is practically impossible a, effect the actuation of the switch withoutfithe use: of special tools.

The advantages of m' invention are thus It wi llfalso be seen-that by locating the switch above the fan and its motor, it is out of the way, and its casing instead of being unsightlytends to add to the attractiveness of thelian in its entirety.

of the switch is readilyfeifected w en the key is secured to this sw h rod,= such key being within easy and convenient reach. The key'may, be readily removed, and thus'lnterference with the fan or switch rendered I claim as my invention! 7 'c In combination, an electric. motor having a tubular shaft, a casing for the motor, a fan located beneath such motor. and designed to be actuated thereb a switch. for the m0- tor located above the atter, a casing for such switch from which the motor casing depends, a depending switch rod extended ongitudiend carries a sleev e 15, of suitable insulating nally through and beyond the motor shaft,

a sleeve of insulating material on the-lower end of said rod, and a key for actuating the rod detachably secured to said sleeve.

In-testimony whereof, I have slgned this specification in the presence of two subscrib ing witnesses.
