The Denmnore Saw-Gummer is shown in Fig. 8. At A are the driving-pulleys, journaled between arms on a lower cross-piece, in which is also socketed the lower extremity f the elevating screw B. On the upper cross-head is swiveled a yoke, to which is journaled a shaft C, carrying pulleys D. These transmit motion from the driving-pulleys A to the pulley £, on tho emery-wheel shaft. The shaft C passes through a metallic block F, which fits loosely upon it, and which is ground off to a point on its under side, to form a bearing for an adjusting screw. This block is also bored to receive the arm G, which supports the grinding-wheel. The arm O is movable in the block, and can be fastened in any desired position by the set screw H. I is a counterbalance for the wheel. J' is a stock, secured in place as desired, by a set screw not shown, and supported from below by the hand-wheel, by which it can be elevated and depressed. The stock has ways for a saw-bar. or a carriage with clamps for the blade. The saw-disk, in case a circular saw is to be gummed, is attached to the end K of the saw-bar, and the latter is properly adjusted and fastened to the stock, in such position as to bring the saw-teeth properly under the emery-wheel. The stock is then adjusted so as to bring it to a proper height by means of the elevating screw, and the arm O is depressed in front until the wheel is in proper position. The wheel is previously adjusted to the proper angle of the tooth by partially rotating the arm in the block F, and securing it when the wheel is at suitable inclination. When the apparatus is to be used to gum a straight-edged saw, the blade is confined in a carriage, and the wheel is set in relation thereto, as already described. The saw is gradually carried forward by the carriage as each tooth is gummed. |
