Abstract

146,737. Jenkins, H. C. Aug. 7, 1919. Cramps.-In valve-spring lifters and compressors of the type comprising two parallel bars such as 1, 5, Fig. 2, connected by crossed links 7, 8 pivoted together at 15, to fixed trunnions 11, 12, and to movable trunnions 13, 14, one of which is actuated by a nut engaging a thread on one of the bars so that the bars have a parallel opening movement, the nut 20 is provided with a flange 19, and the movable trunnion 13 is mounted in a groove between the flange and the head of the nut 20, whereby the nut 20 may be operated to give the bars a. parallel closing movement in addition to the opening movement. In compressing a valve spring prior to removal of the cotter, the end 6 of the lower bar 5, having a U-shaped slot, engages a part of the engine surrounding the valve tappet, and the end 2 of the upper bar 1, having a similar slot, engages the spring stop 3, the bars being given an opening movement. To compress a spring prior to replacing it, the end 6 engages the spring stop 3 and the end 2 engages the spring as shown, the bars being given a closing movement. The bar 1 is cranked at 21 to facilitate replacing the spring where there. is a depending ridge below the valve pocket.
