9 Claims.

The present invention relates to inlaying and particularly to the inlaying of ornaments into articles so as to enhance the appearance thereof.

Numerous articles or parts thereof are manufactured at the present time from plastic molding or synthetic resin materials such as hard rubber, pyroxylin, cellulose acetate, phenol-formaldehyde, urea formaldehyde, casein, et cetera. The appearance f articles such as clock dials, radio panels, automobile instrument panels, fountain pens, signs, boxes and the like is greatly enhanced when inlaid with initials, numbers or other ornamentation.

The present invention aims to `provide a new and improved type of ornament which may be rapidly and inexpensively inlaid into articles, particularly those made of plastic molding materials, and to give a raised or relief eilect not present in ordinary inlaid articles. The invention also contemplates the provision of means for securely holding the ornament in position in an article at all times, and inaddition the provision of an improved method of inlaying the ornament.

An object of the present invention is to provide a new and improved type of inlaid article.

Another object of the invention is to provide an inlaid article having a new and improvedV outwardly projecting inlay secured thereto.

Another object of the invention is to provide a new and improved type of ornament adapted Ato be readily inlaid into an article.

Fig. 11 is a sectional view similar to Fig. 10, but including a base guiding means.

Referring again to the drawing and more particularly to Figs. l to 3 thereof, there is shown a fragment I of an article inlaid with the present and preferred type of ornament 2. The showing of a fragment of an article in Fig. 1 is intended to illustrate the application of the invention to articles generally and to bring out the fact that it is not limited to any particular article. While the invention may be embodied -in an article or a panel thereof made of wood, linoleum and other such substances, it will be described chiefly with reference to an article or panel made of a plasti molding material.

The plastic molding material or base member I which is to be inlaid with an ornament preferably has a main recess, slot or groove 4 adapted to receive the lower part 5 of an ornament 2 and this main recess or groove 4 in turn preferablyhas a plurality of spaced sub-recesses 'l therein at its lower part. The main recess is of substantially the same shape and size as the article which is to be inlaid. In Figs. 1 and 2 a recess is illustrated which is adapted to receive a strip like ornament, but it will be understood that an ornament and the recess are notlimited to strip shape but may be square, round, triangular, or any other desired shape. The main recess 4 and sub-recess I may be molded, cut or otherwise formed in the base member I.

The ornamental member 2, shown as a striplike member herein, is preferably stamped and formed from ilat metal stock into a channel of U-shape. That is, the member is formed so as to have a cover portion 3 in the shape of the desired ornamentation, with a depending flange or skirt 8. Depending downwardly from the flange -or skirt 8 is a plurality of tab-like portions I0. The flange and tab portions 8 and I0 llt, respectively, into the main recess 4 and into the subrecesses 'l formed inthe member I to be decorated.

At the lower part of each of the sub-recesses 'I there is preferably placed a substantially flat metal tab guiding member lIl against which rest the tab portions I of the ornament 2.

Pressure applied against an ornament 2 (Fig. 4) causes the tab portions III to spread outwardly and engage with or embed themselves in the sides of the sub-recesses, the substantially flat metal t'ab guiding member II at the lower `cart of the sub-recesses being effective to guide the tab portions outwardly and prevent their digging into the bottom of the sub-recesses. Preferably a pressure member I3 is utilized to force the ornament 2 downwardly and this pressure member I3 may, if desired, be heated by means of a heating coil I4, the heat generated thereby being transmitted to the pressure member I3 and to ornament 2 so as to cause a localized heating and softening of the plastic member I with which the ornament is being secured.

If desired, the pressure member I3 may be formed with a recess therein, as shown by the dotted lines of Fig. 4, adapted to receive the upper portions of a channel shaped ornament 2.

With this type of pressure member, sldewise movement of an ornament will be minimized and also the lower portion I6 will act to limit excessive inward movement due to the lower portions I6 contactingthe article I and acting as a stop. Also, if desired, the pressure member I3 may be caused to reciprocate rapidly and tap an ornament into position instead of using straight pressure.

In inlaid position the tabs I0, which have been guided outwardly by the plate or flat member I I, are embedded in the sides of the sub-recesses l. The lower edges II of the ornamental me i-- ber 2 intermediate the tab portions I0 preferably rest against the bottom of the main recess 4 intermediate the sub-recess 1. These intermediate edges I1 may be forced into the article I but preferably the portions IIJ are relied upon to hold the inlay in place. The spreading or outward flaring-of the tab portions I0 tends to also pull outwardly of the portions of the depending flanges 8 intermediate the tabs I0. Thus the intermediate flange or skirt portions of an ernamental member are moved firmly into contact with the sides of the main recess 4 so as to further lock and hold an ornament in the recess.

If desired, the main recess 4 need not be utilzed and instead the article to be ornamented may be provided only with the spaced sub-re cesses 'I (Fig. '1). In such a construction the tab portions III are adapted to fltlinto the subrecesses and engage the sides thereof in the same manner as above described. The edges I'I on the flange or skirt portions of an ornament intermediate the tab portions I0 will, in such event, rest against the surface of the article instead of within a main recess.

The substantially flat guiding members or plates Il may be omitted from the lower parts of the sub-recesses 1 but in such event the tabs I0 of an ornament should preferably be flared outwardly slightly so that upon the application of pressure to the ornament, the tabs I0 will be more readily guided outwardly into engagement with the sides of the sub-recesses.

n Since the present type of ornament is not flush with the surface thereof, the inlaid ornament or decoration stands out in relief and provides a three dimensional effect not present in ordinary inlaid articles.

In Figs. 8 to l0 there is illustrated a form of the invention wherein no tabs are utilized on the ornament. This modified type of ornament la is adapted to fit into a main recess 4a similar to the main recess 4 shown and described in connection with the preferred embodiment; no sub-recesses 1 are necessary with this modification. The skirt or flange 8a of the modified ornament Zw is flared outwardly slightly, as shown in exaggerated form in Figs. 9 and 10, so that when it is seated in a recess and pressure is applied to the upper part thereof, the edges I8 and flange 8a will spread outwardly into engagement with the side walls of a main recess 4a. The, ornament 2a may be pressed or tapped into position and heated as described in connection with the preferred embodiment. Like the preferred embodiment the ornament may have a square, circular, triangular or other shape.

Fig. 11 illustrates the modified form of ornament shown in Figs. 8, 9 and 10 utilized with a substantially flat guiding member or plate I9 at the lower part of the recess 4a. The guiding member I9 preferably covers the entire bottom of a main recess 4a so as to more effectively guide the edges I8 and flange 8a of the modified article outwardly into engagement with the walls of a recess. The application of the ornament to an article is similar to that described hereinabove.

It will be seen that the present invention provides a new and improved type of inlaid articles. Ornaments are adapted to be rapidly and securely inlaid into articles, thus facilitating mass production and resulting in consequent lower manufacturing. costs. An article inlaid with the present ornament and by the present method gives a pleasing raised or relief effect not embodied in usual types of ornamentated articles.

As various changes may be made in the form, construction and arrangement of the parts herein without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interrupted as illustrative and not in a, limiting sense.
