Patent number: 4474088Abstract: Tongs are provided for screwing together or unscrewing sucker rods for deep oil wells. A slotted ring gear is placed into a slotted annular housing plate and driven by conventional means. Heads on cage plates are moved by cam on the internal surface of the slotted ring gear. Relative movement between the cage plates carrying the head and the ring gear is governed by the position of a reversible ratchet stop which includes a beveled pin. The beveled pin is mounted in a hole through one of the cage plates and works on a slot in the ring plate. When the bevel is faced in one direction, it permits rotation of the ring gear to the cage plates in that direction, but holds the ring gear and cage plates in the matched position rotation in the other direction. The matched position is when the cams are in a neutral or withdrawn position and when the slots are aligned.Type: GrantFiled: September 2, 1982Date of Patent: October 2, 1984Inventor: Kenneth W. Lee

Patent number: 4471576Abstract: An expandable abrasive tool is provided with an axially-extending slot receiving a single abrasive element and multiple axially aligned and axially spaced apart pockets located circumferentially from the slot with each pocket fixedly receiving an individual centering element for properly positioning and supporting the abrasive element in the hole. The axially spaced apart pockets space the centering elements apart in end-to-end relation and thereby allow torsional flexing of the tool body during hole machining without damaging the brittle centering elements. In an alternative version, multiple centering elements are received in spaced apart end-to-end relation in a single axially elongated slot instead of in individual pockets.Type: GrantFiled: November 15, 1982Date of Patent: September 18, 1984Assignee: Ex-Cell-O CorporationInventor: William G.

The balls prevent the jaws from sliding out of the carriage and from rotating in the carriage. The carriage is driven by a driven head which is connected to the driving means. The carriage and driven head are held in an uncomplicated hollow cylinder which is the body. Grooves in the faces of the jaws cooperate with the balls and allow a limited amount of reciprocation of the jaws within the carriage. Movement of the carriage within the body is not essential, so that the body serves to hold the balls in the carriage and to provide structural support.Type: GrantFiled: March 24, 1982Date of Patent: September 11, 1984Assignee: Titan Tool CompanyInventor: John A.
