OF SAME PLACE.

Letters Patent No. 97,254, dated November 23, 1869.

IMPROVEMENT MACHINE FOR. POLISHING- WOOD.

, The Schedule referred to in these Letters Patent and making part of the same To all whomtt may concern:

Be it known that I, DANIEL WESTLEY, of Corry,

Erie county, Pennsylvania, have invented certain new and useful Improvements in the Construction of Mamanent floor, as maybe expedient. They are also connected with each other at, their upper ends by cross-picces,-not shown in the drawing.

To these jambs are bolted, or otherwise fastened, rehatcd guide-pieces a, forming channels or ways, or. if preferred, the ways may be provided by grooving the inner faces of the jambs.

O is a carrying-frame or gate, reciprocating in the ways just named.

In this frame are placed one or more blocks 0, covered upon their outer face with sandpaper, 0, or other substance suitable for polishing-purposes.

These blocks have their edges bevelled, and fit closely into' perforations having similarly bevelled sides, in frame 0, as shown at M), fig. 2.

They are held in place by a cap, 0', upon the rear side of the gate, as is also shown in fig. 2.

When sand-paper is used, it can be conveniently secured to block c, by pressing the paper around the edges of said block before it is placed in frame 0, and then pressing both block and paper firmly in place, by means of the cap 0, .the inclined edges of the block and corresponding inclined edges of the perforations in frame 0, affording the means of securing the sand-paper in proper position, and also of adjusting the distance which the block projects through the gate.

D is a shaft, mounted in suitable bearings, at the upper endofjambs A.

D is a crank-wheel, keyed rigidly to shaft D; and d is a pitman, connecting wheel 1) with gate 0.

D is a belt-pulley, keyed to shaft D in such position that motion may be imparted to it from some convenient point.

A supporting-frame, on which to slide the doors or other articles to be operated upon, is formed of slotted arms E, sliding in gains in posts A, the uprights E, and transverse bars E.

This frame not only serves to support the door at a proper height, with reference to the gate 0, but also keeps said door in contact with the polishingblocks 0, the slots e, and bolts c, providing for such adjustment as may be rendered necessary by the variation in the'thickness of the doors.

.If it is found to be desirable, the outer face of the block 0 may be padded or otherwise rendered slightly elastic, for the purpose of fitting with more accuracy any inequalities in the surface of the doors, or the transverse bars E may be so constructed as to present a yielding surface, and thus accomplish the same purpose.

From the foregoing description, it. will be readily .seen that if I give the gate or carrying-frame G a rapid reciprocating motion, by means of the crank D' and pitmau (Z, operated by any suitable power, a door or other artiole passed through the supporting-frame, and subjected to the operation of the sand or other polishing-substance, upon the outer face of block 0,

. will be effectually and rapidly polished and finished.

Among the advantages possessed by my machine are its cheapness and durability.

From the fact that the reciprocation of the gate is vertical, the tendency to rack and shake the machine apart is largely reduced, while at the same time the doors can be handled more easily than they could if the polishing-surfaces had a horizontal reciprocation, although, ii'in some cases and under some circumstances, a horizontal reciprocation he preferred. it may be employed. v

What I 012M111 as new, and desire to secure by Letters Patent, is-

1. The reciprocating gate O,- constructed and arranged to operate substantially as shown and described, and for the purpose set forth.

2. The supporting-frame EE E, constructed substantially as shown, in combiuationlwith the carryingframe or gate DANIEL \VESTLEY.
