i and in line, withV those `on the shaft aroundthesechain wheels on thetwo shafts (B, D,) are two endless chains (19), to which the logs are `attached by suitable dogs (la) suspended in the links thereof.
(m) is alever and (n), aconnecting rod, for operating the brake (d) when it is desired to stop the saws. l
The back of the framing (A) between the :bluff andthe saws, is planked up to` form a bearing for the logs" to slide against in their descent; between the frame and the saws aty oneside, is a guide or gage (lo) to guide the log 1n a direct line to the saws, and against which `the logs incline, by a slight inclination of the chains toward that side, or they may be borne against it by a spring and friction rollers, on` the opposite side.` If found in practice that a single `driving wheel would have to be inconveniently large, to. give suiicientspeed to the saws, a countershaftI may be used, with a pulley and `wheel on it of such size as may be found necessary, to give the required speed.
In operating this Imill theV log must be first slightly slabbed on one side to prevent its rolling on the ways, it is then lowered down in any' convenient manner, till the top 4end of it is about level with the upper chain wheels, it is then'secured to the endless chains by the dog (la), near the top, its
weight now being borne by the endless chains (p, 79,) puts the saws in motion, in `descending, the upper saws (7L, z) take a slab off each side; when the dog byV which it is held comes nearly do-wn to the saws, an#
other dog is attached below, and the weighttaken off the upper one, so that it may be removed; as soon as the log is clear of the Vupper saws the mill isstopped by the friction brake (CZ)` applied to the wheel; the log is then turned on lits side, and secured `When the saws areabout halfwaythrough the log, it maybe supported by running a l straight bar of iron through Athe links of the chains, beneath the log, and thedog above the saws removed, so that the weight of the boards remains on the chains, to assist in ldriving the saws `until they reach the lowerl chain wheels, whenthe carrying bar is drawn them on endless chains, Working around chain Wheels, which drive the saws, substantially as set forth.
In testimony whereof, I have hereunto subscribed my name this 15th day of J anuary 1855.
