A tool has an adjustable lie angle, face angle, weight, and shaft length and is used by a golfer to adjust a putter to the optimal lie angle, face angle, weight and shaft length for that golfer. The tool head has a face plate and a sole disposed normal to one another. An angle member has a vertical wall disposed parallel to the face plate and a horizontal wall that overlies the sole. A hosel is pivotally mounted to the vertical wall and a first protractor is fixedly secured to the vertical wall. A marker on the hosel indicates the lie angle on the first protractor. A second protractor secured to the sole indicates a face angle when the shaft of the club is rotated about its axis. Weights are selectively added to the toe, heel, or mid-point of the putter head to determine an optimal weight and weight distribution.

Rotary lobe pump and circumferential piston pump designs are disclosed where the drive and driven shafts are detachably connected to their respective rotors. The rotors are disposed in a pump or rotor casing, which is sandwiched between a head cover and a gearbox. The drive and driven shafts pass through mechanical seal assemblies, which are sandwiched between the first and second rotors and the gear box respectively. The seal assemblies can be serviced or replaced by simply removing the head cover and removing the rotors from the drive and driven shafts. The pump casing does not need to be removed to replace or service the seal assemblies. Further, the capacities of the disclosed rotary lobe and circumferential piston pumps can be modified without changing the gearboxes or shaft length. To modify a pump capacity, all that needs to be changed are the rotors, the pump or rotor casing and, in some designs, the head cover or cover plate. In some designs, the cover plate is universal to the gearbox so that only the rotors and pump casing need to be changed to modify the pump capacity.

The present invention relates to a utility iron which is characterized in that it has a lie angle of 58 to 64°, a loft angle of 20 to 28°, a head weight of 270 to 300g, and a shaft length of 35 to 38 inches. Thus, the loft angle is relatively reduced so as to prevent a golf ball from being hit high and increasing flight distance. Also, because the lie angle is relatively increased, the possibility of a hook or a slice occurring is reduced. Because the weight of the head is increased, repulsive force is augmented by the striking of the golf ball, which relatively increases the flight distance of the golf ball. Because the length of the shaft is relatively shortened, swing trajectory is reduced, and accurate striking is made easier so as to also increase flight distance.
