Application March 28, 1936, Serial No. 71,528

9 Claims. (CL 101-35) Garnish moldings or frames such as are commonly used in automobiles are largely furnished in wood grained designs or an imitation of the wood grain and owing to the irregular shape of 5 these and the cross section, care must be exercised where the entire finish is of a wood grain design in order to avoid overlaps or in order to secure a matchingof the grain applied to different surfaces or zones of the frame by succeed:

in ing steps.

It is the main objects of this invention,

First, to provide a garnish molding or the like with an attractive finish which can be economi cally anduniformly produced.

15 Second, to provide a method of finishing garnish moldings and the like in which adjacent surfaces may be finished with different designs without blurring oroverlapping of either design and giving the appearance of two strips or pieces 9 of material brought edge to edge.

Third, to provide a method of finishing garnish moldings and likeframes which may be practiced by relatively .unskilled workmen with uniformity of results.

25 Fourth, to provide an apparatus for use in the applying of ornamental coatings to garnish moldings and the like which enables high production with desirable and very uniform results.

Objects relating to details. will appear from 30 the description to follow. The invention is defined and pointed out in the claims.

A structure which is a preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

In the accompanying drawing, no attempt has been made to show the parts in their relative dimensions andcertain of the views are largely of diagrammatic character.

Referring to thedrawing, the frame or garnish 10 molding I is of channel cross section having an inner surface 2, a face surface 3 and an inner side flange 4. Commonly, the surface of the flange 4 is not exposed, so that its finish is not important.

It is now quite common practice to finish the

surfaces

2 and 3 with wood grain coatings or wood grain designs and owing to the angular relation of these surfaces it is difiicult to apply the coatings so that they do not overlap, thus resulting in a smudgy appearance, or so that they meet completely-in either, case requiring hand work or retouching to secure an acceptable finish.

The grain design coating is applied by means of a transfer roller 5 formed of suitable resilient composition such as printing roll composition,. the roller having handles 6 at each end for manipulation. The design is picked up from a suitably inked printing plate, the design being indicated on the roller at I. This'grain design coating is applied to the inner surface 2 of the molding by passing the roller around the inner surface, resulting in a grain design coating 8 on the frame as indicated in Figs. 1, 5 and 6.

In applying the grain design coating to the surface 2, it is quite impossible to-maintain a straight line or edge for the coating adjacent the surface 3. Necessarily, portions of the irregular margin of the grain 'design will overlap onto surface 3 as designated by reference numeral 80 in 40 Fig. 9. Therefore, as a second step of my method, I-wipe the surface3 by pass ng thereover a resiiient cleaning roller equipped th means for keeping it clean, a resilient roller of the composition used for applying the coating being suitable for the purpose, such roller being indicated at 9 in Fig; 3. The roller 5, suitably cleaned, may be used as the wiping roller, but I have, for convenience, designated the roller by another numeral. To accomplish this step, the'work or molding I is laid upon a suitable bed or table I0 and the roller 9 translated across the same with uniform pressure, the roller with itscleaning mechanism being preferably carried in a carriage H by traveling on rails I2 at the side of the table. rigs cleans the surface I and picks up any ink that overlaps thereon, bringing the edge of the coating 0 to a straight edge It-see Figs. 5 and 6, Fig. 5 being intended to show the molding after the wiping operation. I

r I then apply to the surface 3 a coating or symmetrical pattern indicated at llin Figs. 1 and 6, this pattern being approximately symmetrical throughout. This surface 3 is coated by passing the roller across a suitably inked plate, then passing the roller across the surface 3 in Fig. 5. This may be accomplished by placing the roller in the carriage H and by holding the carriage down upon the tracks. Uniform pressure is applied to the roller so that its design is applied to the surface 3 and brought to the meeting line It with the previously applied coating 8 so that the two coatingsare brought edge to edge without substantial overlap and retouching is unnecessary or substantially eliminated with reasonable care in the following of the successive steps.

The design or pattern of the coatings ll being approximately symmetrical-that is, a two-way pattem-it may be applied by passing the transfer roller across the frame or molding as indicated in Fig. 7, the applied design being approximately symmetrical "throughout as well as beingbrought into edge to edge relation to the grain design.

This produces a very attractive finish and one having the appearance of two materials brought edge to edge, one having a grain design and the other a formal or symmetrical design. This results in a substantial reduction in the cost of applying the ornamental finish and enables the obtaining of uniform results with relatively unskilled workmen.

cle is highly attractive in appearance.

In the embodiment shown in Fig. 8, the molding or work is laid upon a conveyor l5, being secured thereon by the clips or clamps l6 and is translated or carried past a pair of wiping rollers i1 equipped with cleaning mechanisms or doctors l'lll which wipe the surface 3 and brin the previously applied coating to a straight edge. It is then brought into contact with the transfer roller i8 coacting with the cylinder plate lflwhich in turn coacts with the ink transfer roller 20 to which ink is applied by the ink roller 2!. In this embodiment, the wiping and printing or coating operations for the surface 3 are entirely automatic, the work being clamped upon the conveyor i5 and thereby translated through the wiping and printing or transfer rollers.

I have illustrated certain apparatus for prac- As stated, the finished arti-.

ticingmy method partially in conventional form, but it is believed that this disclosure will enable the construction of a suitable apparatus either in automatic or hand operated machines or apparatus. I have not attempted to illustrate and describe the various modifications and adaptations which I contemplate as it is believed that this disclosure will enable those skilled in the art to practice not only the methodbut to provide suitable apparatus for the practice thereof.
