Letters Patent No. 188,063, dated March 23, 1869; anteelctcd March-10,1869.

To whom it may concern.-

Know all men, that I, ISAAC H. NEWTON, of Grand Rapids, in the county Kent, and State of Michigan, have invented a new and useful Improvement in the Apparatus Used for Handling Lgs in Saw-Mills; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, and being a part of this specification.

Figure 1 is a sectional View of one side ,of my apparatus, with beam removed to -show the mechanical construction of the cants.

Figure 2 is a plan View of that part of my`apparatus which is beneath the oor of the mill, and fastened to the same.

The saine letters indicate similar' parts in each ligure.

I obtained a patent for an apparatus for handling logs in saw-mills, March 19, 1867, and my present application is for an improvement on that apparatus; and

Its nature consists in the operation of the cantinglever, and the mechanism to attain this operation.'

To enable others to better understand my improvement, I willv describe the whole apparatus and its operation, confining myself, in the claims, to what I actually have improved, and not desiring to claim the whole apparatus.`

The nature of my invention consists, specially- First, in the reciprocating rod F, provided with shoulder G, operated by the hook-lever E, and actuating thc canting-lever H, as will be more fully described hereafter.

Second, in the combination with the above of the cant I, when constructed and operating as will be described.

Third, in the device for lowering the cant I, consisting of lever K, trippers L, and pins M, as will be described.

Fourth, in the. combination of the cants I, cantingdrum A, fastened around which is the cord D, passing over and along the upper timbers of the mill to a point over the carriage, descending over a proper pulley, and terminating in a proper hook.

Near each end of the shaft B, are the cams E E, fixed to and rotating with the shaft. p

F F are connecting-rods, provided with shoulder G, and engaging withv the canting-levers H.

I is the -cant which turns the log upon the carriafre.

is a shaft under the iloor of the mill, upon one end of which is a lever, K. Upon this shaft, and under the ends of the connecting-rods F F, are the trippers-L L, which, when` not in use, rest upon the pins M M.

Having thus designated the various parts of my apparatus, I will now proceed to describe the method of using the same, promising, however, that Ythe clutch C is out of gear.

The log to be turned being on the log-way, immediately over the cant I, the point of the cant-hook being inserted into the side of the log next the saw, the drum A is thrown into gear with the clutch G, revolving with the shaft B, which winds the rope D around the drum A, causing the log to make onefourth of a revolution, the toe of the cam E engaging with the shoulder G ofthe connecting-rod F, carrying it back, and causing it to raise the cant I, by means of thecanting-lever H, to an angle of about forty-five degrees, thus causing the log to slide forward upon the carriage after being turned. The cants are then lowered to their horizontal position, by raising the lever K, which causes the trippers L L to disengage the shoulders G of the connecting-rods F F from the toes of the cams E E, thus causing the connecting-- rods F F to slide forward, and thereby lowering the y canting-levers H and the' auts I to their proper positions.

What I claim as my invention, and desire to secure I
