Application filed February 23, 1893. Serial No. 468,447. (No model.)

To aZZ whom it may concern: extending horizontally through the platform Be it known that we, CHARLES BATEMAN on which the skidways are mounted to the and WILLIAM H.

The skids, as seen in Fig. 4, have lonhaving been turned off the skidways or platgitudinal grooves g along their bottom edges form onto the carriage conveying the same to adapted to permit the rods eto operate therethe saw. It is our object to combine such in in rotating or throwing the cams a. In the 65 contrivanoe with the usual stationary skiddrawings such groove is shown as extended ways on the platform, and to place the operalong the entire length of said bottom edges ating of the same under the control of the of the skids and the lifting-arms 0, provided sawyer, so as to economize labor.
