Patent number: 6539640Abstract: A plumb bob system for allowing an individual to easily utilize a plumb bob in determining whether a wall is plumb. The plumb bob system includes a pole, an engaging structure attached to an upper end of the pole, a pulley rotatably positioned within the engaging structure, a spool containing a length of string passing about the pulley, and a plumb bob attached to the end of the string opposite of the spool. The engaging structure is comprised of a first member and a second member having a first edge and a second edge respectively. The first edge and second edge have a common length of radius from a center point of the pulley to provide an average upper distance (Z) of the string from the wall. The center of the plumb bob has a distance from the lower portion of the wall (X) that is compared to the upper distance (Z). If the upper distance (Z) and the lower distance (X) are equal then the wall is being constructed plumb and no modifications are required in the construction of the wall.Type: GrantFiled: October 30, 2000Date of Patent: April 1, 2003Inventor: Raymond L.

Patent number: 5392522Abstract: A plumb bob having a central body portion and at least three substantially identical webs extending outwardly from the body portion along respective radial axes. The angles separating each successive web must be equal to maintain vertical symmetry, and an even distribution of weight, with respect to a longitudinal axis extending centrally through the body portion. In addition, the webs uniformly and linearly taper in a decreasing manner from the top end to the bottom end of the body portion. This geometry permits a worker standing in vertically aligned position above the plumb bob to be able to clearly see both the bottom end of the plumb bob and the preexisting datum from which alignments are being made.Type: GrantFiled: May 3, 1993Date of Patent: February 28, 1995Inventor: Michael J.

Patent number: 4934060Abstract: A golfer's aid for helping a golfer determine the contour of a putting green and a method of assembling the golfer's aid are disclosed. The aid includes a plumb bob and a plumb line having a first end secured to the plumb bob and a second end secured to a cylindrical shaft which is mounted in a golf ball shaped casing. The casing has a first hemispherical half and a second hemispherical half which are snapped together to form the casing. When snapped together, the first and second hemispherical halves define a chamber for housing the plumb bob. The walls of the chamber, in turn, define an inner bore for receiving the plumb line and an outer bore for receiving the plumb bob. The first half of the casing also defines a round hole for rotatably receiving a first end of the shaft. The second half of the casing is provided with a shaft retaining ring for rotatably receiving the other end of the shaft.Type: GrantFiled: August 8, 1989Date of Patent: June 19, 1990Inventor: Paul L.

Patent number: 4920657Abstract: The assembly includes the plumb bob and line, and a cylindrical rotor mounted eccentrically for eccentric rotation about an axis of rotation. The line is connected at one end to the rotor and at the other end to the plumb bob. The rotor may be rotated to pay out and retract or wind in the line. The plumb bob may be stored within the casing. Side walls of the casing perpendicular to the axis of rotation closely confine the space beyond the rotor ends to confine the line as it is winding in.Other features include a conical sheath to receive the point of the plumb bob and arms to hold the cylindrical body of the bob; also a dentent cooperating with the casing and the folded handle may be used to hold the handle and the rotor fixed.Type: GrantFiled: October 23, 1987Date of Patent: May 1, 1990Inventor: Richard A.
