Abstract

295,828. Gallagher, J. Aug. 15, 1927. Bush extractors. - A. device for extracting valve seatings, bushes &c. comprises a normally expanded member consisting of a number of pivoted claws adapted to be passed down in contracted condition within the seating &c. and then to expand automatically into engagement with its inner edge. The claws 6 are pivoted at 5 on a spider 4 sliding on a threaded rod 1 fitted at its lower end with a nut 2 and washer 3. To insert the device within the valve seating 11 the claws 6 are pressed inwards and maintained in this position by screwing down a nut 10 which presses the lower ends of the claws into contact with the washer 3. After inserting the device in the valve seating the nut 10 is slackened to enable a spring-pressed disc 7 engaging the heels of the claws to expand them into the position shown with the toes 6<a> ta.king under the lower rim of the seating. A lever is then connected to the screw for removing the seating, or a bridge device 12, 14 may be mounted against the valve casing 13 and the extraction effected by a nut 15.
