FEED MECHANISM FOR SAW-MILL CA RRIAGES.
SPECIFICATION forming part of Letters Patent No. 307,348, dated October 28, 1884.
Application filed June 9, 1883. (No model.)
To all whom it may concern,
Be it known that I, JOHN W. Sronon, of Manistee, in the county of Manistee and State of Michigan, have invented new and useful Improvements in Saw-Mill-Oarriage "Feeds; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to certain new and useful improvements in devices for giving the necessary reciprocating motions to saw-mill carriages; and the invention consists in the peculiar construction, combination, and operation of the various part-s, as more fully hereinafter described.
Figure 1 is a side elevation showing the engines situated upon the ground-floor of the mill and the carriage upon the operating-floor. Fig. 2 is an end view of the same.
In the accompanying drawings, A A represent a pair of vertical engines, both of the same dimensions and capacity, suitably secured below the operating-floor of the mill.
Bis a shaft running in suitable bearings, which may be supported from the operatingfloor of the mill or from below, as circumstances or discretion may dictate. This shaft is situated immediately above the two engines,
'and at each end it is provided with a crank and pin, 0, the one at one end being set quartering to the one at the opposite end, and these cranks are connected by suitable rods, D, to the pistons of their respective engines. Centrally secured upon this shaft is a spur-wheel, E, preferably made of steel, on account of the lesser liability to accident, although it may be made of cast-iron, if preferred. This wheel meshes into and engages with a rack, F, secured by a central longitudinal rack-stick, G, to the carriage H.
I represents the timbers of the operatingfloor of the mill, upon which the carriage travels upon a suitable track, in the usual manner.
gines, and arrangements such as are usually employed forthe purpose are made for reversing by the sawyer on the operating-floor of the mill.
I am aware that it has been proposed to move a sawcarriage by means of two vertical shafts carrying pinions which mesh with a rack on the under part of the carriage; but in motion has been derived from a single engine, and I therefore make no claim to such construction.
I am also aware of Patent No. 176,409, and
therein.
gines, fortheir use allows of the crank-connections being set quartering, thereby making and having centrally secured thereon the rackwheel E, constructed and arranged to engage with the rack F, substantially as and for the purpose specified.
