V l V I The Schedule referred to in these Letters Patsnt and making part of the same.

To all whom it may concern `Be it known that we, BELA. L. CHURCHILL and GEORGE Z. VANDERSLICE, of Philipsbnrg, in the county of Centre, and State of Pennsylvania, have invented certain new and useful Improvements in Sawf Mills; and we do hereby declare that'the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, making part ofthis specification, and `to the letters of reference marked thereon, like letters indicating like parts wherever they occur. A To enable others skilled in the art to construct and use our invention, we will proceed to describe it.

Our invention relates to saw-mills; and It consists in a novel arrangement of devices wheref bythe action of the carriage, in its backward or return movement, is caused to turn the log, for slahbing and similar'operations.

In the drawings- `Figure lis a side elevation of our device in opera- .tion, and Figure 2 is a top plan view 'of the same.

A is the carriage, constructed in the ordinary manner, and provided with the usual dogs or head-blocks B.

C is the saw-log in position on the carriage. D is an overheadcross-beam, forming part of the r frame-work of the mill, andhaving pivoted to or above it, auarm'or lever, E, extending parallel withthe line oftravel of the carriage, as shown in bothigures.

. F is along depending arm or push-bar, attached to the bar E near its 1niddle,`and the lower end of which .may be engaged in teeth` or notches e, made in the carriage forthat puipose, so that as the carriage is moved backward, the push-bar will raise the lever E. As ,the push-bar does not push squarely under the lever E, but a little from one side, a rope or chain, 1',

"is secured from the end of' the lever to the end of the cross-beam, as shown iniigs. 1 and 2 to prevent any lateral movement ofthe lever G is a long rope or chain, attached to the free end of the lever E, and provided, on its lower end, with a rope or chain' passed around the back end ot the log, and 'the hook driven firmly into it, as shown in igs.'

l and 2. The carriage is then moved backward, causl,ing the, push-bar to operate the lever E, which, draw'- ing upon the'rope G, turns the log over.

log is turned' the required amount, the push-bar and` the hook are disengaged, allowing` the log toremain When the stationary on the carriage, while it finishes its movement.

To the cross-beam we attach a bar, H, having an arm, J, at its end, on which the push-bar is rested f when not in operation, so as to be out of the way.

backward movement of the carriage, in connection with the lever E, rope or chain G, and push-bar F, `as Set forth. l
