SCOTT I. PHELPS, OF CINCINNATI, OHIO.

MOLDING-POLISHER.

EIECIPICATION forming part of Letters Patent No. 337,515, dated March 9, 1856.

Application filed February 18, 1.?5.

To a/ZZ whom, it may concern:

Be it known that I, SCOTT I. PHELPS, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Molding or Cornice Polishers, which in'iprovement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a top or plan view of my molding'or cornice polisher. Fig. 2 is an end elevation of the same, showing a piece of molding in position to be polished. Fig. 3 is a cross vertical section of the wh el for. holding the sand-paper; and Figs. 4, 5, 6, and 7 are sectional views of the different conformations of the guidepieces used in the machine, against which the cornice or molding rests as it approaches the polishing-wheel.

The object of my invention is to construct a machine for polishing molding for cornices; and it consists of a table having thereon at one side a vertical shaft or mandrel, which carries on its upper end ahorizontal wheel which rotates on a plane directly above the top of the table. The rim of this wheel is removable in sections, so as to provide for placing therein rims of different shapes and conforma- This rim receives the sandpaper, to which it is clamped, and the whole is rotated at a high rate of speed, the molding or cornice beingmoved along the edge of the wheel against guides of suitable eonformation, all of which will now be set forth in detail.

In the accompanying drawings, A represents a table mounted on a suitable t1 ame, B. J ournaled to this table, midway between the ends and at one side of the center, is a vertical shaft or mandrel, 0. Near the lower end is a pulley, D, by means of which it is rotated, and the upper end carries a Wheel having a solid rim, E, and four or more spokes, E. On the under side of the rim E, and projecting beyond the rim E, is a flat ring, G, and directly on top of the rim E is a ring, II, similar to the ring G, except that it does not project ever the rim E as far as the ring G.

I is a removable rim, ofeither metal or wood, and made entire in one piece or in sections, and this rim is designed to be of that conformation in cross-section which corresponds Serial No. 156,202. (No model.)

with the kind of molding or cornice that is to be polished. Before this rim I is placed on the ring G around the rimEitis covered with sand-paper or emery-paper, and alter it is placed on the, ring G the ring H is placed on the rim E, and bolts J passing down through the ring H, rim E, and also ring G, clamp the rim I and sand-paper firmly in position. In addition to the clamping-rings H G, and particularly when the rim I is made in sections, I place a disk, K, on the upper end of the shaft 0. I provide the hub of the wheel with aseries of holes, L, and place a pin, M, through a similar hole, M, in the rotatable disk K.

N represents loops designed to be placed around the rim I in a suitable groove, so that the said loops will not project beyond thet'are of the rim I.

0 represents connecting-rods, which extend from the disk K to these loops, so that when the disk K is turned and the pin M placed in the holes M L the sect-ions ol' the rim will be held lirnilyin place and prevented from being thrown oil by the great velocity imparted to the wheel. The table at one side of the wheel is provided with removable guide-pieces. These guide-pieces P in cross'sectiou are designed to conform with the shape of the mold ing to be polished, and are also to be of the same conformation in cross-section as the rim I,\vhich holds the sandpaper. Thus, Figs. 4-, 5, 6, and 7 show the different kinds of guidepieees that may be employed, and corresponding wdt h'each of the. conformations shown in these figures is the rim I, so that the rim I and the guides ,I? alike may be removable and changed at, ,will, thereby greatly increasing the efficiency of the machine by adapting it for various kinds of molding.

S is a piece of molding which is in position to be polished.
