LIQUID CONTACT CONNECTER.
Application led January 27, 1927. Serial No. 164,048.
-The genera-1 object of this invention is to provide means for making an electrical connection between a stationary part and a rotary part without the use o f brushes or the like.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims..
In describing my invention in detail, reference will bev had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a longitudinal sectional view through the invention.
Figure 2 is asection on line 2-2 of Figure 1.
Figure 3 is a perspective view of the ring attached to' one of the rotary connecters.;
In'. these views, 1 indicates a casing which forms a. stationary part`of Athe device and 2 indicates the cover therefor which is rotatably mounted on the casing. Both ofthese parts are formed of insulating material and a tube 3, also of `insulating material, is formed with or connected to the bottom of the casing 1 and projects a considerable dis-y tance above the top thereof.- The cover 2 is provided with a socket 4 for receiving the upper end of the tube 3. Mercury or the like is adapted to be placedl in the casing 1 and in the tube, as shown at 5. A conductor 6 extends through the bottom of the casing 1 and projects into'the mercury in the tube 3 and a conductor 6 .has its bent end extending through the side .o f the casing 1 adjacent the bottom thereof; and projects into the mercury in the 'said casing.l A conductor'7 extends through the cover and projects into the tube'3 and contacts with the mercury therein while a conductor 7 passes throu h the cap into the casing and extends into t e mercury in the said casing. A ring 8 is connected with the lower end of the conductor 7 -andis immersed in vthe mercury in the casing 1. This ring' surrounds the tube 3.. Suitable packin material 9 is placed 1n the upper end o the tube and in the upper end of the casing 1 to prevent the mercury from leaking from the device, this case, the cover 2, with the conductors 7 and 7 would be attached to the rotary part of the fan, while the part 1 would be stationary wit-h the base of the fan.
It will, of course, be understood that the device can be used in other situations.
It is thought from the foregoing descrip- I tion that the advantages and novel features of my invention will be readily apparent.
'I desire it to be understood that I may make changes in the construction and in vthe combination and arrangement of the several parts, Vprovided that such changes fall with- 1n the scope of the appended claims.
