These rubbers were adjustable within 5 In the accompanying drawings, Arepresents an arc of a circle or within the slots of the a frame, preferably of rectangular form, and arches, and also were vertically adjustable by supported by suitable legs a. The frame A screws and nuts; but the function or purpose has secured to it, near one end thereof, a la of the rubbers was not analogous to that of 50 ble, B, of metal or other suitable material, the elastic rollers E, the same, as previously we stated, being to guide and keep the molding in proper position and in contact with the feedrollers N.

Secured to the frameA forward of the table B are the boxes for containing the composition, of the kind usually employed for coating wood moldings. Thesecomposition-boxesconsist of two sides, F G, supported by brackets H, being laterally adjustable upon the frame; or, if desired, one only of the brackets may be adjustable by a set-screw, e, passing through the elongated slot f in the base of the bracket, for adjusting the sides F G to or from each other, for the purpose of adapting the width of the boxes to the varying widths of the molding. Upon the outer faces of the sides F G are lugs g, with screw-threaded openings therein to receive tension thumb-screws h, the lower ends of which engage with similar lugs '5 on the sides of the brackets H. A coil-springflt, passes around each of the thumb-screws h, and is disposed between the lugs g i, for the purpose of relieving the molding as it passes through the composition-boxes from the weight of the sides F G, and thereby insuring the desired quantity of composition to be deposited on the surface of the molding both evenly and smoothly, which would not be the case were the sides of the composition box or boxes not properly supported. The tension of the springs k is regulated by the screws h to elevate or depress the sides F G, as circumstances may require.

shoulders and lugs are rubber or other suitable springs m, so as to render the boxes or sides thereof yielding in a vertical direction, so as to accommodate them to the increased thickness of the molding caused by the several coatings or layers of composition thereon as it enters the boxes, thereby insuring a better and more uniform coating, which is indispensable in a perfect operating machine.

The sides F G are independentof the brackets H, and are provided upon their outer faces with vertical grooves 11, which engage with shoulders 0 of the brackets H, to steady and guide the sides in their vertical adjustment. The sides are slotted, as shown at p, to receive templets I, held therein by suitable set-screws q. These templets are in form and shape to correspond with the form and shape of the molding, and they may be removed, and others of different patterns secured in their place, as required. The interior surfaces of the sides F G are provided with longitudinal shoulders 1, which serve to guide the molding through the boxes, so that the molding forms a traveling bottom for the boxes, an d receives its coatin g therefrom.

Secured to the frame A, and upon each side thereof, are scrapers K, of steel or other suitable metal, and which may be adjustable to suit or adapt them to moldings of different widths, and may also be detachable from the frame, and replaced by others of difierent shape, as required by the special design of the molding that is being coated.

The scrapers K have sufficient elasticity to perform their office in scraping or removing the composition from that portion of the molding where it is not required.

To the under side of the frame A, and across the same, are secured bridges L, which support tracks Mat right angles thereto, orlen gthwise of the frame A, to support the molding within the composition-boxes and while pass ing through the same. These tracks M have screw -threaded rods upon their under side, which pass through elongated slots in the bridges L, by which arrangement the tracks are adjustable to or from each other and held at the desired distance apart by suitable nuts upon the screw-rods bearin g against the under side of the bridges, and also elevated orlowered by the addition of a nut upon the upper side of the bridge, as shown in Fig. 6. This lateral or horizontal adjustment is for the purpose of increasing the width between the tracks to accommodate them to the width of the molding being coated.

The vertical adjustment of the tracks M is to compensate for the wearing away of the peripheries or faces of the feed-rollers.

The feed-rollers N, upon the under side of the table B, are composed of rubber, having their shafts t in suitable hearings in the sides of the frame A, and the rollers are rotated by suitable gear-wheels P Q, attached to the ends of the shafts t and communicating motion to each other by a pinion, a, motion being imparted by a drive or other suitable wheel, B. Any well-known means, however, may be employed to impart the desired rotary motion to the rollers N, either by hand or other suitable power. The rollers N pass up through openings in the table B, so as to have their periphery above the upper surface thereof, to bring the rollers in contact with the under side of the molding, thereby causing the molding to be forced or carried along to the compositionboxes toreceive its coating. The rubber rollers N, by continued contact with the under surface of the wood molding, wear away to such extent that the periphery of said rollers will no longer come above the table B, and the consequence would be that the rollers would not act to feed along the molding to the composition-boxes. Provision, however, is made for this wearing away of the feed-rollers by the vertical adjustment of the table, which is accomplished by set-screws w. fore be seen that as the feed-rollers N wear away, the table B, with its gages O, is lowered sufficiently to have the rollers come above the surface of the table to operate upon the molding.

It should be noticed that the tracks M are also vertically adjustable to bring them on the same plane as the table B, and the rollers E are directly over the feed-rollers N, so that It will therethe molding upon its upper surface is pressed down with sufficient force to insure the perfect operation of the rollers N upon the moldmg.

When a special form of molding is to be coated the templets I are replaced by others of the required form, and secured by the setscrews q within the slotted ends of the sides F G, the sides being first adjusted to conform to the width of the molding, as are also the gages O and tracks M- The molding is 'now placed between the gages G, and is fed along by the rollers N to the boxes, which are filled with any of the well-known compounds usu-' ally employed for preparing moldings for gildmg.

The manner of supporting or connecting the sides of the composition. boxes to the brackets H, and at their forward ends only, admits of their rising automatically to allow of the molding passing under the templets I.

In order "to give the required evenness or smoothness to the surface of the composition and have it of the requisite thickness upon the molding, the latter is passed through the machine a number of times until it receives a sufficient number of layers or coatings of the composition to produce the effect desired, the scrapers K, as the molding passes along, removing therefrom the surplus composition.

The composition-boxes, slotted arches, and the pressure-rollers connected thereto, also the feed-rollers, may be multiplied or increased in number, as found desirable.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for enameling or preparing moldings for gilding, the combination, with the feed-rollers N, having their journals in the stationary frame A, of the table B, having openings through which pass the peripheries of the rollers, said table being vertically adjustable with relation to the position of the rollers, substantially as and for the purpose set forth.

' 2. The frame A, having journaled therein feed-rollers N, in combination with the table B, having openings to receive the peripheries of the rollers, said table being vertically adjustable with relation thereto, and carrying laterally-adjustable gages 0, substantially as and for the purpose set forth.

3. The slotted arches D, having adjustably secured thereto boxes I), in combination with the holders 0, carrying rollers E, and the screwrod d, for adjusting the holders, substantially as and for the purpose specified.

4. The combination, with the laterally-adjustable brackets H, of the movable sides F G and templets I, substantially as and for the purpose described.

5. The sides F G of the composition-box, secured by a vertically-yieldin g attachment, substantiall y as described, to the adjustable brackets H at one of their ends only, so as to admit of their tipping or rising at their free ends to accommodate the templets to the varying thickness or irregular surface of the molding, substantially as and for the purpose specified.

6. The combination, with the brackets H and sides F G of the composition-box, of the tension screw-rods h and the springs k m, for rendering the box yielding to the inequalities of the surface of the molding, substantially as and for the purpose specified.

7 The combination, with the vertically-adjustable table B, of the vertically and laterally adjustable tracks M, arranged under the composition-boxes, substantially as and for the purpose described.

8. The composition-boxes composed of the laterallyadjustable sides F G and the templets I, in combination with the vertically and laterally adjustable tracks M, substantially as and for the purpose specified.

9. The frame A, having journaled thereto the feed-rollers N, and the independent vertically-adjustable table B, carrying adjustable gages O, in combination with the adjustable rollers E, adjustable tracks M, and adjustable sides F G of the composition-boxes, substantially as and for the purpose set forth.

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

WILLIAM GLASGOW.
