Abstract
775,471. Extracting rail spikes, KENRITA CO., Ltd., and PANNELL, E. J. Oct. 22, 1954 [Nov. 25, 1953], No. 32763/53. Class 61 A device for extracting spring steel rail spikes having hooked heads from sleepers comprises a working head 10 slidable on a guide pillar 12 which is pivoted at 16 to an operating lever 15 having weights 17 fixed to each end. A link 23 is provided at 24 to the head 10 and is connected through a lost motion coupling 21, 22 to another link 18 which is pivoted at 20 to the lever 15. The end 27 of the pillar 12 is slightly convex to allow the pillar 12 to be located in a groove 28 in the baseplate 29 and held upright. The head 10 has a spike receiving recess 30 having upper and lower surfaces 31, 32 conforming to the contours of the head of the spike. To operate the device, the lever 15 is swung in a clockwise direction to take up the lost motion in the coupling before the extracting force is exerted.
