Another type of marine drag-saw used at some plants is shownin Fig. 18. In this type, the equipment is mounted on a float, moorednear the foot of the incline. Power for driving the saw is derived fromthe steam cylinder A. The latter is supported on trunnions at B, sothat the saw may be raised or lowered by means of the pulleys andweight shown in the diagram. The logs are held firmly against thefloat by the vertical dogging arm C, the base of which can be movedaway from or toward the float by the piston in the cylinder D. Spikeson the end of the dogging arm C prevent the log from slipping whileit is being sawed. 38 SAWMILL EQUIPMENT. By permission Hill-Curtis Co. Fig. 18.—A Marine Drag Saw. A.
