  1. 1
    I claim as my invention:1. The combination of a member having two oppositely-extending targets and a central part 45 connecting said targets and having a slot traversing said part and extending lengthwise between said targets, and a shaft extending through said slot and freely supporting said member, said member being rotatable on the shaft and being movable thereon longitudinally of the slot to bring either end wall of the slot into contact with 5 the shaft, and the center of gravity of said member being substantially coincident with the center of the slot.
  2. 2
    The combination of a member having two oppositely-extending targets and a central part 10 connecting said targets and having a slot traversing said part and extending lengthwise between said targets, and a continuous, stiff wire forming a centrally arranged shaft, stops extending upwardly from the ends of the shaft, and support- 15 ing standards extending downwardly from the stops, said shaft extending through said slot and freely supporting said member, said member being rotatable on the shaft and being movable thereon longitudinally of the slot to bring either end wall 20 of the slot into contact with the shaft, and the center of gravity of said member being substantially coincident with the center of the slot.
  3. 3
    A member comprising two oppositely-extending targets and a central part connecting said 25 targets and having a slot traversing said part and extending. lengthwise between said targets, the center of gravity of the member being substantially coincident with the center of the slot.
  4. 4
    The combination of a member having two 30 oppositely-extending targets and a central part connecting said targets and having a slot traversing said part and extending lengthwise between said targets, and a shaft extending through said slot and freely supporting said member, said 35 member being rotatable on the shaft and being movable thereon longitudinally of the slot to bring either end wall of the slot into contact with the shaft, the center of gravity of said member being substantially coincident with the center of the .40 slot, and each target having a forward surface visually distinguishable from the forward surface of the other when the member is in an upright position with either target above the shaft.
