摘要： A new plaster cutting device for cutting grooves into cracked portions of ceilings and walls. The inventive device includes a housing having a hollow interior. The hollow interior has a forward chamber and a rearward chamber. An elongated handle extends angularly upward from the housing. The elongated handle has a hollow interior. A motor is secured within the rearward chamber of the housing. The motor has a rotatable gear disposed on an end thereof. A cylindrical wheel is rotatably disposed within the forward chamber of the housing. The cylindrical wheel has a plurality of cutting teeth disposed thereon. The cylindrical wheel has a gear disposed on an end thereof. A belt extends around the rotatable gear of the motor and the gear of the cylindrical wheel whereby activation of the motor will facilitate rotation of the cylindrical wheel.

摘要： The control rod includes an upper absorber section and a lower velocity limiter comprised of a socket, a vane, a transition piece and a set of fins. To adjust the weight of the control rod, lighter and heavier sets of fins, as well as lighter and heavier transition pieces are provided. By suitable selection of the lighter and heavier sets of fins and the lighter and heavier transition pieces, the weight of the velocity limiter can be selectively adjusted in accordance with the weights of differently designed sections to obtain a predetermined control rod weight. Additionally, the heavier transition piece may have material removed therefrom to decrease its weight to provide an infinite adjustment of weight within a predetermined range of weights for the velocity limiter.
