Definitions

  • This invention relates to electric switches of the kind used to control the motor that drives the compressor of a mechanical refrigerator, and the principal object is to provide a simple, ineiipensive article that can be easily installed and aci-- justed, and will endure a long period of service.
  • Fig. 2 is a vertical Section on the line 2-2 of Fig. 1;
  • Fig. 3 is a plan section on the line 3 3 of Fig. 2.
  • Fig. i is arperspective View of a displacer for ⁇ the mercury
  • Fig. 5 is a perspective view of the bracket which forms the base and support, and
  • Fig. 6 is a perspective view of a yoke forming part of the agnet.
  • the mercury tube switch includes the glass tube or envelope I0 sealed o at the top, ⁇ forming a sort of conical tip II and pinch sealed at the bottom forming a flattened projection I2.
  • Conductors I3 and I Q are sealed through the bottom and Il extends well up into the tube where it is bent over and doubled back on itself to form an electrode I5 for contact with the mercury I 6.
  • the displacer is a hollow cylinder I'I of glass, lava, Alundum, or the like, around which is an armature Iii-made of Some ferrous material.
  • cylinder I'I is provided with ribs or flanges I9 to prevent accidental displacement of the armature
  • the armature has ⁇ fingers 2U at each end bent outwardly to form guides for contact with the inner surface of the tube I8. Their tips ZI are ened and will have sufficient resilience to gripy the cylinder I1 While the fingers 20 will be hard the switch, and means to enough'tc endure a long period of service. Carbon steel can also be used.
  • the amature has a vertical slit 22 to prevent eddy currents when the switch is used with alternating current. 5
  • a flange 2B on the yokev 29 has holes 21 for screws, or bolts, to secure the device in place.
  • the coil 28 is inserted between the arms of the yoke and the mercury tube switch passed through those arms and the coil.
  • the magnet can be easily adjusted by loosening the screw 33, and slipping the yoke up or down, as the case may be, and tightening the screw.
  • a coil In a device of the class described, a coil, an iron yoke having aligned openings in its arms, a mercury tube switch in the coil and projecting through the openings, a bracket having arms engaging the ends of the switch and means for se- 2.
  • a bracket In a device of the class described, a bracket having upper and lower arms, a mercury tube switch between the arms and resting on the lower one, a coil encircling the switch, a yokehaving open pole arms spanning the coi-l land receiving fasten the yoke to the bracket. 50
  • a bracket having upper and lower forked arrns, a mercury tube switch received at its ends between the forks of the respective arms, a coil surrounding the switch, a yoke spanning the coil and grasping the 55 swit and means to fasten/the yoke to the bravenet.
