JAMES L. PERRY, OF BERLIN, WISCONSIN, ASSIGNOR OF ONE-HALF TO CHARLES A. MATHER, OF SAME PLACE.

WOOD-POLISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 240,179, dated April 12, 1881.

Application filed October 2, 1880.

To all whom it may concern:

Be it known that I, JAMES L. PERRY, of Berlin, in the county of Green Lake and State of Wisconsin, have invented a new and valuable Improvement in Wood-Polishing Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a longitudinal section of the device. Fig. 2 is a' plan view. Fig. 3 is an enlarged view of the brush. Figs. 4 and 5 are enlarged sectional details of the rollers.

This invention relates to wood-polishin g machines. It has for its object the construction of a device whereby plane surfaces of wood maybe polished and deprived of all superficial fibers in such a manner as to effect an exact and perfect finish.

The invention consists in the combination of rotary reducers, consisting of polishingrollers and a finishing-brush, the construction of the rollers, the relative position and adj ustability of the brush, and other details, all as hereinafter specified.

In the annexed drawings, A is a frame suitably constructed to accommodate the machinery.

B is the top, consisting of the receiving-table M, depositing-table N, and the cross-barb and bearing b, and having the openings D E F. To each end of the openings D E is located a standard, D E, having a slot, d e, in which slots are seated the journal ends of the presserrolls D E", adjustable therein by blocks and screws. Pivoted near the bottom of each of said standards D E is a pair of sector-hangers, D E, having near their outer edges the grooves d e. Seated in said grooves d e are the feed-rollers d d e e, the rollers 61' 0 being adjustably held by spring presser-blocks and screws.

Immediately under opening D, with its peripheryprojectingabove the face of said opening, is hung a roller, H, upon shaft H. In a similar position with regard to opening E is hung, upon shaft 1, a roller, I. Below said (No model.)

rollers are located troughs K K, having bottom outlets, k k.

Below opening F is hung, upon shaft L, a brush, L.

The construction and operation of the rollers and brush is this:

The body of roller H has in its surface longitudinal oblique grooves h, and between said grooves, and extending to the edges thereof, are sections of carpet h and paper felting h. Covering such sections and surrounding the roller is a covering, first, of rubber h, and then sand-paper h, said rubber and paper being held in place by strips H, which press them into the grooves h. This kind of roller operates very well where a high degree of pol-.

of rubber and sand-paper; but the sections inside are differently made up. In said Fig. 5, I is the body of the roller, having grooves 1'. Between said grooves, and reaching to edges thereof, are the sections, which are made ofthe following material: Next the body portion 1 is a layer of Brussels carpet, i, with the face outward, then a layer of paper felting, f, and outside this a layer of Brussels carpet, g, with the face inward. Outside these are fastened the rubber 7c and sand-paper l by the strips P, secured in grooves "6. By this construction the loops of the carpet are turned toward each other, with the paper felting between, whereby a line degree of elasticity is given to roller, and the edges l I meet the work with a smooth, gradual yielding pressure, and the fibers are neatly reduced and an exact polish given to the surface.

The finishing-brush L is attached to the table N by hangers R, the journals of the brush being inserted in blocks 1", which slide up and down in slots 1" of hangers R, and are ad justed therein by screw r. The position of this brush in relation to the frame is such that the periphery of the brush is on a line with the tops of bearings b and n, which said bearings act to support the work as it comes fromthe rollers, by which construction the tips of the bristles alone act upon the work and remove the fine fibers which may have been left by the rollers. It will be seen that this whipping action of the tips of the bristles produces this result, for if the sides of the bristles struck they would merely sweep off the dust, but would not affect the fiberswith the same precision and consequent finish as the tips.

The depositing-table N swings upon the pin 0, which enters slots *r" in curved arms B. By this arrangement table N and brush L can be swung aside and the roller I readily reached.

The work is presented to the machine upon table M, and is fed throughthe feed-rollers to roller H, from thence to roller I, and from this to L, and is then received upon the table N. The two rollers H and I and the brush L are run each independent of the others and at different rates of speed, the roller H and brush L moving in one direction, meeting the work, and roller I moving in the opposite direction, moving with the work. By this device the board is first caught by roller H, and the fibers are dressed off one way, and then the roller I cuts them the other way, and the brush L, by its whipping action, removes any fine fibers or filaments which may have been left by the rollers. It will thus be seen that the action of these reducers, moving successively in opposite directions and at different rates of speed,

is such that each succeeding reducer operates to remedy inaccuracy in the preceding one, by which construction and arrangement work presented to the machine has all superficial fibers removed and receives a high degree of polish.

I claim 1. In a wood-polishing machine, the combination of the two polishing-rollers, the finishing-brush, and means, substantially as described, for adjusting the brush with its tips just in contact with the object to be polished, as set forth.

2. A roller having a body portion, fillingsections composed of two pieces of Brussels carpet, and an intermediate layer of paper felting, the faces of the two pieces of carpet being turned toward each other, with their loops bearing against the paper felting and the cox'erings of rubber and sand-paper.

3. The frame carrying the polishing-rollers, in combination with the table carrying the brush and hinged to the frame.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JAMES L. PERRY.
