- SIGNORS BY MESNE ASSIGNMENTS, TO SAID JAMES L. PERRY AND CHARLES A. MATHER, OF SAME PLACE.
- Ourinvention relates to machines for fi-nishing or polishing wood; and it consists in the construction and novel arrangement of the several parts, whereby this object'may be accomplished, as more specifically described hereinafter, and pointed out in the claims, and whereby smooth and even work will be produced, whether the board to be operated upon be straight, serpentine,or circular.
- the letterA designates the frame of the machine, which should have a convenient'rectangular form and. be provided with suitable bearings for the gearing and mechanism hereinafter described.
- Bis the feed table' or platform having a transverse opening for the feed-rolls, guards, and sand-paper cylinder.
- J 0 represent the feed-rolls, arranged in pairs, one pair on each side of the central opening, D, of the-feed-table and extending across the same parallel with the axis of the sandpaper cylinder.
- the journals of the feed-rolls O 0 turn in hearings in the lower portion of the arc-shaped ends of swinging arms E, of which latter thereare four in number, a pair being pivoted to the spindle b of the gearwheels F on each side 01'' the machine.
- Each of the feed-rolls U is provided with a gearwheel, a, on each of its ends, and these gearwheels mesh with cogs on the periphery of wheels F, which (the cogs) extend down along the inner faces of the wheels to form bevelgearing, by which they (the wheels F) are turned through the medium of a pair of shafts,
- h h are branches that extend obliquely upbearings f f on each side of the frame of the 7 machine, and the'lower ends of the rods L are connected by a transverse rod-bearing, k, with which the bifurcated inner ends of the weigh tlevers N engage, the weight-levers having a constant tendency to throw the rods-Lop and cause them tolift the outer ends of the arms E, that are connected with rods L by the branches h, to carry the peripheries of the feed-rolls C out above the top of the tableB, so that when the stuff is fed into the machine it will be car ried away from the sand-paper cylinder, unless a sufficient pressure is brought upon it from above'by mechanism such as we will describe further on to cause it to depress the feed-rolls.
- presser-roll R Intermediate between the presser-rollsG we journal a large presser-roll, R, in bearings 9, that slide up and down in slotted standards h, and are adjustable vertically by means of screw-bolts g.
- the axis of presser-roll R is parallel to and on a direct vertical line with that of the sand-paper cylinder H, and the pressure of the stuff upon the sand-paper cylinder is determined by adjusting this roll up and down to cause it to overcome the lifting force of the lever N, acting through the arms a ward from vertical rods L, that reciprocate in E and feed-rollers C.
- a shaft, k is transversely arranged in bearings at the side of the rod It, and forms the fulcrum of the weight-levers. It is provided with arms I, which engage under the long arms of said weight-levers when its handle l is raised and serve to raise the same, allowing the feed-rolls to fall, and thus the feed-rolls may be simultaneously adjusted thereby as well as independently by means of the adjustin g-screws, hereinbet'ore described.
- the sand-paper cylinder H is provided with spiral grooves m, in which are seated wedges to,-
- feed-'rolls' U having stationary hearings in swinging arms
- presser-rolls having yielding and adjustable hearings in said arms above the bearings of the feed-rollers, as setforth.
